Causality and logical fallacieis in old wives' tales and old farmer's Essay

Causality and logical fallacieis in old wives' tales and old farmer's tales (tales are given) - Essay Example y arise because of observing some instances where they became true, so people shared these stories as facts, and these beliefs are subsequently passed on to others. The flaws in the logical reasoning behind these tales are: first, non sequitur because conclusions about these superstitions do not necessarily follow from the premises; second, hasty generalization because anecdotal evidence does not support the external validity of superstitions; third, confusing cause and effect because factors that happen together are not always related as cause and effect; and fourth, appeal to fear because black cats are related to witchcraft and demons. The old wives’ tale about pregnant women shows non sequitur because the effect of having a child who becomes a musician does not always follow from the practice of listening to music while pregnant. The exact source of this superstition is not well-documented, although some of these stories are likely to come from European countries that are fond of listening to classical music in the past. These mothers might have been incidentally listening to music while pregnant, so when their children became musicians, they immediately attributed the latter’s musician skills to their pregnancy habits. Nevertheless, even if it was true for some mothers, it does not follow, which is non sequitur, that every mother who follows the same practice will also have children with musical skills. Believing in this relationship results to another fallacy called hasty generalization. Even if some pregnant mothers attest that they listened to music regularly while pregnant, and that this practi ce provided musical skills to their children, their small sampling cannot be applied to the entire population of mothers who follow the same habit. It will be hasty generalization to assume that the practice of a small group generates effects that are applicable for the whole population. Anecdotal evidence is not enough to prove the external validity of the

Environmental Problems, Mitigation Measures and Effectiveness Essay

Environmental Problems, Mitigation Measures and Effectiveness - Essay Example The other anthropogenic activity is destruction of the natural environment by unsustainable use of resources, a factor that has also resulted in world climate changes (Dalby, 2002: 44). Atmospheric pollution is the main cause of global warming; it results from the accumulation of carbon IV oxide and other greenhouse gases in the atmosphere, trapping heat from the sun in the earth’s atmosphere. Greenhouse gases are by-products of industrial combustion, which means that the extent to which a country contributes to global warming by these gases depends on the level of industrialization; a high level of industrialisation causes increased consumption of fossil fossils. Fossil fuels like natural gas, oil and its products have a high carbon content that is released in huge quantities and at a faster rate than can be sequestered by natural carbon sinks like forests and oceans. In this case, first world nations and rapidly developing third world nations are the main contributing agents to environmental degradation by industrial pollution. On the other hand, environmental degradation can occur due to unsustainable use of natural resources like forests and water bodies; this is a serious problem in developing countries (Adil, 2005: 315). The economies of these countries are primarily agricultural based; the high rate of population growth necessitates high agricultural production for food security. However, deteriorating climatic conditions have reduced the productivity of land in these areas, forcing people to clear more forests for agricultural purposes. Consequently, forests that play a role in precipitation are destroyed, and the areas receive less rainfall; this has a negative effect on agricultural productivity, which forces further clearance of forested areas. This cycle goes on and on until many of productive lands have become barren, especially due to poor farming practices and the dependence on rains for agriculture in these countries. Some of the effects of environmental degradation include loss of biodiversity; decreasing ice coverage on mountain tops and poles that pose a threat to sustenance of the hydrological cycle; and desertification by loss of vegetation cover. Moreover, it causes climatic changes like extreme weather conditions whereby dry areas get drier, hot areas hotter, and wet areas wetter; and a rise in sea level that destroys sceneries and property (Barry and Eckersley, 2005: 255). Based on the economic implications of these changes and their threat to survival of life in the planet, governments and international organisations have taken measures to mitigate the effects of the environmental problems that result from these changes (Carter, 2001: 282). These measures target the two main aspects of environmental degradation including pollution and unsustainable use of resources; there have been some level of success though with some limitations too. This paper discusses the measures taken by governments and internationa l organisations; the extent of success of these interventions; the limitations facing effective implementation of interventions; and the consequences of these measures. Intervention Measures Governments have come up with environmental policies that aim at encouraging adoption of environmentally sustainable approaches by their citizens. For instance,

Advantages of Composite Construction

Advantages of Composite Construction With regards to Civil and Structural Engineering, composite construction typically refers to the use of steel and concrete formed together so that the resulting component behaves as a single element. The aim of composite construction is to utilise the best properties of the different materials and to deliver performance that is greater than had the individual components been used together but not unified. In the case of steel and concrete, the best properties would be the tensile capacity of the steel and the compressive capacity of the concrete. (Nethercot, 2004) Composite construction is an effective method of construction and delivers good performance. The methodology for designing composite structures has been researched in great detail. For these reasons, composite construction is a very popular method of construction around the world. In order for the materials to behave as one element, it is necessary for some method of connecting the two materials. A shear connection between two materials will enable composite action between them. (The Institution of Structural Engineers) 2.1.1 Benefits of Composite Construction The benefits of composite construction include speed of construction, performance and value. Steel framing for a structure can be erected quickly and the pre-fabricated steel floor decks can be put in place immediately. When cured, the concrete provides additional stiffness to the structure. Additionally, the concrete encasement protects the steel from buckling, corrosion and fire. Service integration within the channels on the composite decks is another advantage to composite construction. Building quality standards can be adhered to easily by the use of pre-fabricated decks. Excessive deflections can be controlled by cambering the beams or by shoring the metal decks to limit deflection when concrete is poured. 2.1.2 Codes for the Design of Composite Structures The design of composite structures was governed by the British Standards. BS 5950-3-1 dealt with the design of beams whilst slabs were governed by BS 5950-4. Pre-fabricated decking used with composite structures was governed by BS 5950-6. Since the introduction of the Eurocode set of standards for the European Union, the design of composite structures is standardised by Eurocode 4. (BS EN 1994-1-2) (BCSA; TATA Steel; Steel Construction Institute) 2.1.3 The Principle of Composite Action The principle of Composite Action underpins the use of composite materials in construction. It relates to the interaction of two or more separate elements acting together and contributing together rather than separately. By physically connecting them, the strength of the beams and the resistance to bending, shear and torsion are significantly increased. The Principle of Composite Action is best illustrated as an example. The diagrams below shows two uniform concrete beams placed on top of each other and loaded with a uniformly distributed load. Both beams will resist the load independently and there will be relative movement between them. The bending strength will be the sum of the individual beams contribution. If the beams have width w and height h, the bending strength M will be: However, if the two beams are connected rigidly together by shear connectors and the relative movement between them is eliminated, the width remains w whilst the height becomes 2h. The bending strength M will be: This represents a doubling of the bending strength through the use of composite action. This is the principle behind the use of steel beams with reinforced concrete floor decks. The two are connected by shear connectors. The increase in strength due to composite action can be as much as 20%, resulting in lighter and thinner sections. (TATA Steel) Figure : The differences between identical beams when composite action is utilised. The beam on the left is comprised of two concrete beams that are not connected compositely. When loaded, there is relative slip between the beams. The component beams on the right are rigidly connected together by means of shear connectors. When loaded, there is no slip between the beams and the assemblage behaves as one large beam. Image from TATA Steel. 2.2 Composite Floor Deck Slabs Composite floor decks are comprised of either steel beams or concrete embedded steel beams together with a reinforced concrete slab. The profiled steel formwork that supports the concrete floor during casting is of vital importance as it also provides the shear bond to enable the materials to work compositely. The role that the profiled decking plays in fire resistance will be discussed in more detail in Section 3.3. Composite action is achieved between the beams and slab by the use of shear connectors that will be discussed in Section 2.4 in more detail. (Metal Cladding and Roofing Manufacturers Association, 2003) The profiled steel decking used in the construction of composite floor systems contributes significantly to the ease and speed at which the structure is construction. It acts as both the permanent formwork and contributes to the overall requirement of reinforcement. The performance of the steel decking when exposed to fire needs careful consideration and is dealt with in Section 3.2. Additional reinforcement is positioned in the troughs of the decking to ensure adequate performance in fire. Benefits associated with using profiled steel decking are reduced dimensions and weight of the overall structure. They also provide satisfactory performance in the areas of strength and economic constraints during construction. (Michel Crisinel, 2004) 2.2.1 Types of Composite Slabs The classification of composite slabs depends primarily on the geometry of the steel deck profile used. Shallow decks are classified by depths in the range of 120-200mm whilst deep decks are classified by depths in the range of 200-350mm. (Aida Rodera Garcia) The most common composite slab consists of the profiled steel decking and concrete cast in-situ. Once cured the concrete and decking act compositely. Sufficient interaction between the concrete is achieved by a chemical bond and a mechanical bond facilitated by the shape of the decking. In design, it is common to neglect the contribution from the chemical bond as it is unreliable. There are many different types of profiled decking available and contribute to the classification of the slab. (Nawy, 2008) Pre-cast concrete slabs can also be used to form a composite floor deck system. The slabs must be designed specifically so that they can interact with the beam system in place. The composite action in this case can be achieved by welded shear studs and transverse reinforcement across the floor deck. By utilising pre-cast concrete decks, hollow core slabs can be used. These can reduce the weight of the whole building whilst offering similar performance to solid slabs. Pre-Cast slabs are usually covered by a layer of concrete after installation to produce a more finished and aesthetic result. Figure : Examples of Hollow-Core Slabs The final type of composite floor slab is the Slim Floor. This consists of the supporting steel beam being encased in the concrete with the lower flange of the beam supporting the floor. Diagrams depicting the various composite slab types in use today are shown below. Figure 4: Proprietary Slim Floor System Slimdek- TATA Steel Figure 3: Example of Solid Slab with Topping and Encasement cast In-Situ Proprietary Slim Floor System Slimdek- TATA Steel http://ars.els-cdn.com/content/image/1-s2.0-S0143974X99000759-gr5.gif 2.2.2 Design Composite floor decks are comprised of permanent formworks of profiled steel decking. The decking serves to support the concrete during casting and before it has cured sufficiently to support itself. It is important to ensure that after curing sufficient interaction between the concrete and steel has developed so that the assembly behave compositely. The rebar is placed in the steel decking prior to pouring as is a steel mesh that serves to minimise cracking over supports and to increase the fire resistance of the floor deck. Most decks achieve a satisfactory degree of shear connection with the concrete by the presence of embossments and indentations along the profile of the decking. This type of shear connection is known as a shear bond. (Steel Construciton Institute, 1994) The decking also contributes to the stabilisation of the structure against lateral torsional buckling of the steel supporting sections and transfers wind loading forces to the walls and columns. The decking also serves to minimise cracking of the concrete slab during expansion and contraction such as during curing and fire. This will be further discussed in Section 3. (Aida Rodera Garcia) The steel decking is normally in the range of 0.9-1.5mm thick and has a yield strength of 280-350 N/mm2. Higher strength steels may be used if the spans are longer than the norm. Typical spans for a composite floor deck are between 2.7 and 3.6m although longer spans may be achieved by shoring the deck during construction. Galvanisation of the faces of the decking is done to prevent damage to the steel during pouring and in service. 2.2.2.1 Concrete Type Strength Both Normal Weight Concrete (NWC) and Light Weight Concrete (LWC) may be used in composite floor slab construction. The most convenient method for concrete placement is by pump. The concrete type and grade is an important design consideration as it affects the final stiffness of the deck system and the strength of the shear connection. 2.2.2.2 Steel Decking Resistance The elastic moment resistance of the steel decking may be calculated from the effective breadth of the steel elements in compression. Stiffeners are present in the deck design and contribute to increasing the effectiveness of the section. In designing a deck system, moment redistribution is not allowed. This results in an underestimate of the critical load for the decking. (ECCS, 1993) 2.2.2.3 Deflection Deflection limits for a composite slab are generally the span/180. However, by shoring the composite slabs during casting, this can effectively be reduced to zero. Increased deflection limits of span/130 are allowed if pooling of the concrete occurs in the middle of the span after pouring. (ECCS, 1993) 2.2.2.4 Transverse Reinforcement The strength of the concrete should be checked to ensure it is capable of receiving the force transferred from the shear connectors. Where the concrete may be susceptible to cracking, the provision of transverse reinforcement perpendicular to the beam is required. (Aida Rodera Garcia) 2.2.3 Failure The ultimate moment resistance of a composite slab is defined as the point at which less than 2mm of longitudinal slip has occurred between the concrete and the decking. Failure of a composite deck is deemed to have occurred when slip of more than 2mm occurs. Failure most commonly occurs during curing before the concrete has reached its design strength. 2.2.4 Fire Resistance of Composite Sections The minimum slab depth will be determined by the fire insulation requirements and the amount of reinforcement that is necessary to withstand loading at the fire limit state. This will be dealt with in more detail in Chapter 3. 2.3 Composite Beams A composite beam can be structurally described as a T-Beam, with the top flange composed of concrete in compression and the steel section in tension. Forces between the two materials are transferred by shear connectors. The principle of composite action with regards to beams leads to increased strength and stiffness of the system whilst using a smaller steel section. The two main variants of composite beams used today are shown in Figure 6. Beams are usually composed of a UKB or UKC section, partially or fully encased in concrete for strength and fire resistance purposes. (ECCS, 1993) 2.3.1 Design In composite beam design, the steel section is first sized to adequately support all the loads acting on it. No contribution is taken into account from the concrete as it has not gained adequate strength for composite action. A common value for the load applied to the beam from the concrete slab is 0.75kN/m2. Once the loading has been calculated, the beam is designed according to Eurocode 3. The presence of steel decking normal to the steel section provides lateral restraint to the beam. In this case, the beam can reach its full plastic moment. In cases where the presence of steel decking is parallel to the beam, the beam is only laterally restrained at the connections at either end and the buckling resistance of the beam must be calculated based on its effective length. The effective breadth of the concrete flange, taken from the supported slab, is approximated as the span/8 on both sides of the beam. This results in an effective breadth of span/4 for simply supported internal beams. 2.4 Shear Connectors Shear connectors are an essential element of composite construction if it is to perform adequately. The main purpose of the shear connector is to provide longitudinal shear resistance between the materials so that they act compositely and to facilitate the interaction between the different materials and to allow them to act as one. (MCRMA, 2003) The shear connection between steel beams and concrete slabs is typically achieved by headed steel studs, welded to the top flange of the steel beam and subsequently encased in concrete. The performance of the studs depends on their dimensions and the spacing along the flange of the beam. Near supports, where the shear forces are greatest, the spacing is reduced. Shear studs can be welded through steel decking. Welding shear studs to the steel beams has a number of limitations and guidelines. The flange of the steel beam has to be bare and can not contain any contaminants such as intumescient paint used as fire protection or moisture. This method also works best when the thickness of the steel decking is less than 1.25mm. Weather conditions will also affect the use of this method of connection. Excess moisture in the air can result in the finished weld being brittle and prone to sudden failure. Shear connectors can also be placed during production although mistakes in placement can be difficult and costly to correct. The purpose of a shear connector is to primarily resist lateral shear forces and displacement between the beam and concrete slab. However, they are also designed to prevent upward displacement of the slab from the beam as it has a tendency to do. For this reason, the studs are headed to provide vertical resistance to seperation. 2.4.1 Types of Shear Connectors In the past, the most common method of shear connection was a headed stud. As welding is only suitable for decking with a minimum thickness, where the decking is too thin, nailed studs are used instead. The choice of which shear connector is used ultimately depends on the shear resistance required and the grade and strength of concrete used. There are four main types of shear connector in use today. The most common is the headed stud. However, with the advent of thinner composite decks, the use of headed studs is not practical. This had led to the introduction of nailed sheets of shear connectors. The dimensions of the most common stud are 19mm x 125mm and the method of connection to the steel beam is ceramic disk welding. (Aida Rodera Garcia) 2.4.1.1 Headed Studs The most common form of connecting materials compositely is with the use of headed shear studs. The behaviour of headed studs does not vary significantly when concrete properties are changed. Resistance to shear depends on the number of studs used and performance is less that that achieved by more modern shear connectors such as the Perfobondstrip or a welded T-Section. (Zingoni, 2001) The advantages of stud connectors is that the welding process is quick and simple, the placement of the studs does not interfere with the placement of reinforcement within the slab and they provide uniform resistance to shear in all directions normal to the axis of the stud. (Johnson, 2004) 2.4.1.2 Oscillating Perfobondstrip The curved form of an oscillating perfobondstrip provides better force transfer between steel and concrete than a continuous strip. The load capacity of this connector is larger than a headed stud or welded T-Section. This form of connector is most suited to light weight concrete or high strength normal weight concrete. Problems with this form of connection are difficulties in welding the section to the steel beam. (Zingoni, 2001) 2.4.1.3 Continuous Perfobondstrip The continuous perfobondstrip is similar to the oscillating perfobondstrip but achieves lower resistance values in all categories of concrete type and grade used. For this reason it is not as widely used as the oscillating form although welding is easier. 3.3.1.4 Welded T-Section Welded T-Section connectors perform very well in comparison to headed studs and achieve the same load resistance as oscillating perfobondstrip. Load capacity increases when Light Weight Concrete or high strength concrete is used. The strength comparisons of the shear connectors described above are shown in Table 1 below. The results were obtained from Galjaard and Walraven (2001) from tests carried out to Eurocode 4 standards for push-out resistance. It can be seen that large differences in resistance and ductility were observed. (Aida Rodera Garcia) 2.4.2 Shear Connector Design The choice of which shear connector design is open so long as it possesses the ductility and provides the necessary shear and separation resistance to the composite system. Headed studs are the most common form of connection and the design of such will be dealt with in this section. The design of shear connectors and composite slabs is given in Eurocode 4. Partial safety factors (ÃŽÂ ³v) of 1.25 for ultimate, 1.0 for serviceability and 1.0 for fire are specified in the codes. (Steel Construciton Institute, 1994) 2.4.2.1 Spacing The correct placement of studs along the upper flange of the beam is of great importance. It is important that the flange of the beam be clean, dry and free of contaminants such as paint or fire protection material. A number of conditions for the placement of studs are described below. The upper flange thickness may not be less than 40% of the diameter of the headed stud. After pouring, the head of the stud should have a minimum of 20mm cover. The minimum edge spacing of the headed studs is 20mm, to facilitate welding. Transverse spacing of headed studs must be greater than or equal to four times the diameter of the headed stud. Longitudinal spacing of the headed studs must lie between the minimum of five times the diameter of the headed stud and the maximum of 800mm or six times the overall depth of the slab, whichever is smaller. (ECCS, 1993) 2.4.2.2 Resistance of Shear Connectors The failure of a composite floor deck slab and the failure of shear connectors occurs due to either the strength of the concrete being surpassed or the strength of the weld connecting the studs to the flange of the beam failing. Shear connection design resistances are taken as the minimum of either the concrete or the headed stud. The equations for the design resistance of the concrete and the headed stud are given below. Where: d is the diameter of the headed stud. The ultimate tensile strength (fu) is most commonly 450N/mm2 and should not exceed 500N/mm2. The characteristic cylinder strength of the concrete is given by fck. Ec is the mean value of the secant modulus of the concrete. The values for different concrete strengths are given in the Annex Table 4. The value for ÃŽÂ ± is governed by the ratio of the height of the slab to the depth. The values of ÃŽÂ ± are given below. For 3 à ¢Ã¢â‚¬ °Ã‚ ¤ h/d à ¢Ã¢â‚¬ °Ã‚ ¤ 4, ÃŽÂ ± = 0.2(h/d +1) For h/d > 4, ÃŽÂ ± = 1.0 The partial safety factor () given by 1.25 in the ultimate limit state. (ECCS, 1993) Figure 10: Bearing stress on the shaft of a Headed Stud Connector (Johnson, 2004) 2.4.2.3 Degree of Shear Connection The degree of shear connection is based on whether the required numbers of shear connectors necessary for the composite beam to develop its full plastic moment have been installed. If fewer than the required amount necessary have been installed, the moment resistance of the composite system will be less than the maximum. The degree of shear connection is given by the equations below. Where Rc denotes the compressive resistance of the concrete slab and Rs denote the tensile resistance of the steel section. Both values are given by the equations below. Where hc is the depth of the concrete slab above the profiled decking. Eurocode 4 also provides provision for the minimum for the degree of shear connection based on the span (L) of the composite beam. These ratios are given below. For: L à ¢Ã¢â‚¬ °Ã‚ ¤ 5m, N/Nf à ¢Ã¢â‚¬ °Ã‚ ¥ 0.4 5m à ¢Ã¢â‚¬ °Ã‚ ¤ L à ¢Ã¢â‚¬ °Ã‚ ¤ 25m, N/Nf à ¢Ã¢â‚¬ °Ã‚ ¥ 0.25 + 0.03L L > 25m, N/Nf à ¢Ã¢â‚¬ °Ã‚ ¥ 1.0 (ECCS, 1993) Chapter 3 Composite Steel Deck Floors in Fire 3.1 Background The performance of composite steel deck floors in fire has been much studied to assess the design considerations that must be implemented and for designing the rules for reinforcement placement. In general, composites perform well in fire due to the insulating properties of concrete and the role of correctly placed mesh reinforcement and metal decking. (BCSA, Corus, SCI, 2007) Research conducted in the UK has concluded that previous methods of designing composite floor decks for fire scenarios was over conservative and that composite floor performance in many common fire scenarios was satisfactory. (Steel Conctruction Institute, 1991) Composite steel deck floor systems are typically not provided any fire protection material although the supporting beam to which the floor is connected is fire protected. The profiled decking of a composite floor acts as some of the tensile reinforcement of the system. For this reason, it is important to account for the effects that elevated temperatures will have on the decking. (Steel Conctruction Institute, 1991) The main contributor to the fire resistance of a composite slab is the embedded rebar mesh in the slab. As the temperature of the profiled decking increases in a fire scenario, the resistance that it provides is neglected. Additional reinforcement in placed in the slab to compensate for the loss of strength of the decking at elevated temperatures. The embedded reinforcement mesh is insulated by concrete and maintains a temperature sufficient for load bearing at the fire limit state. The positioning of rebar within composite floors typically results in higher concrete cover compared to normal reinforced concrete slabs. This results in good fire performance as the temperature of the reinforcement will rarely approach critical levels. The positioning of the reinforcement in the upper of the slab also contributes to controlling spalling in fire. The decking of a composite does play an important role however in maintaining the integrity of the concrete slab during fire. It limits the passage of flame and hot gases into direct contact with the concrete and controls spalling. 3.2 Load Resistance in Fire Design of composite slabs in fire conditions is based on the ultimate limit state properties. A composite floor slab is assumed to behave in bending as either a simply supported or continuous element. The load resistance of a composite floor deck system is due to the floor behaving as a reinforced concrete slab with loads being resisted by the bending action of the slab. Failure of a slab in fire occurs as a result of reinforcement failure. (Corus Construction Industrial, 2006) 3.2.1 Methodology There are two main methods for calculating the fire resistance efficiency of a composite floor deck system, referred to as the fire engineering method and the simplified method. 3.2.1.1 Fire Engineering Method The fire engineering method is based on the assumption that in the fire limit state, the plastic moment capacity of the floor is reached at higher temperatures and that redistribution of moments occurs where the slab is continuous. Temperature gradient experiments have produced temperature profiles such as those present in the Eurocodes. These profiles can be used to calculate the capacities of the beam in both hogging and sagging bending. The capabilities of the beams in the fire limit state can then be assessed. 3.2.1.2 Simplified Method The simplified method involves little or no calculation and relies on test data of actual fires to design the reinforcement in the composite slab. The density of the mesh can be adjusted to account for point loads and increased moment around supports. In general, the simplified method will deliver a result that demands less reinforcement in the design whilst the fire engineering method will allow greater flexibility in positioning the reinforcement and customising fire resistance time periods. The use of different grades of concrete will affect the dimensions and composition of a composite slab. Light Weight Concrete (LWC) has better insulating properties versus Normal Weight Concrete and its use will result in thinner slabs. 3.2.1.3 Design Period Deflection Limits The fire resistance of a composite floor deck system is measured as the time that a floor system can maintain sufficient load-carrying ability, maintain its integrity or by limiting heat transfer through the slab. The load-carrying ability of the composite floor system is measured by the amount of deflection that the system undergoes during fire exposure. Deflection greater than the span/30 is deemed critical as is a deflection rate greater than span2/9000d mm/min between deflections equalling span/30 and span/20. The integrity of the composite floor is deemed satisfactory for fire resistance if it can limit the passage of flame and hot gases. The insulating properties of concrete are deemed sufficient for fire resistance if after fire exposure, the upper surface temperature of the concrete slab remains below 140 °C. (Steel Conctruction Institute, 1991) 3.2.1.4 Reinforcement Fire resistance of a composite deck is attributed to the positioning of reinforcement in a mesh configuration within the slab. The most common forms of mesh are A142 mesh (6mm wires at 200mm c/c) and A193 mesh (7mm wires at 200mm c/c), the numbers referring to the cross-sectional area of steel per metre run, although larger gauges may be used if necessary. The tensile strength of the reinforcement is typically 450-500N/mm2. The positioning of the mesh is in the upper portion of the slab with a minimum cover and can be arranged to resist hogging or sagging bending or a combination thereof. (Aida Rodera Garcia) 3.3 The Fire Engineering Method The fire engineering method for composite slab design is discussed in this section. The partial safety factors at the fire limit state for materials and loads are outlined below. Materials: Steel: ÃŽÂ ³mr = 1.0 Concrete: ÃŽÂ ³mc = 1.3 Loads: Dead: ÃŽÂ ³fd = 1.0 Imposed ÃŽÂ ³fi = 1.0 3.3.1 Materials In conjunction with a suitable design fire scenario, it is possible to account for the reduction in strength of both the reinforcement and the concrete in fire conditions. With elevated temperatures, a reduction factor K may be used to account for the loss of strength associated with the increase in temperature. The table of reduction factors is given in Annex Table 5. The equations used for assessing the design strengths of the reinforcement and concrete at elevated temperatures including the reduction factor (K) are given below. Reinforcement: Concrete (Steel Conctruction Institute, 1991) 3.3.2 Depth The minimum depth of the concrete slab is taken from the tables below. Different values are obtained depending on the type of decking used, such as trapezoidal or re-entrant, and the concrete grade. This minimum depth satisfies the insulation requirement for composite slabs during fire exposure. Alternatively, the minimum depth may be taken from experimental test results from buildings of a similar design. (Steel Conctruction Institute, 1991) (Aida Rodera Garcia) 3.4 The Simplified Method The simplified method consists of installing a layer of mesh (A142, A193 or similar) in the upper layer of the concrete. One of the main differences between the Fire Engineering Method and the Simplified Method is that relatively few calculations are required for the Simplified. An outline of the Simplified Method is a follows: Imposed loads on a composite floor deck slab should not exceed 6.7kN/m2. The mesh size is chosen based on the required fire resistance period and the span of the slab. The minimum cover to any part of the mesh must be at least 15mm and not greater than 45mm. The span of a composite floor slab designed using the Simplified Method is typically 3.6m although spans greater than this may be used if adequate calculation is carried out. 3.5 Comparison of Methods While no method is definitively better than the other, they both have advantages over the other. The Simplified Method is more economical and is based directly on test results and not on theoretical calculation, which has a tendency to under-estimate the strength of materials. The Simplified Method also takes into account the contribution from the profiled steel deck even though the contribution may be small compared to that from the reinforcement mesh. The Fire Engineering Method however allows great flexibility in the customisation of the reinforcement and fire resistance periods. It is generally more expensive to design using this method as opposed to the Simplified Method though will result in thinner slabs that utilise more reinforcement. 3.6 Shear Connectors in Fire The performance of shear connectors in fire has not been widely studied. One of the major research projects on shear connectors in fire was The Restrained Beam Test conducted by British Steel as part of the Cardington Fire Tests in January 1995. The test consisted of the heating of a secondary beam and an area of the surrounding slab on the seventh-floor of the test structure. The steel section tested was a 305165 UB40 that was heated along 8m of its 9m length. Only the top 70mm of the concrete slab was taken into account. This was the maximum height of the slab above the troughs of the profiled decking. (Huang, Burgess, Plank, 1999) The temperature distributions in the steel beam and concrete slab were taken as averages of the test results recorded across the cross-sections of the components. The temperature of headed studs exposed to fire was approximated as 75% of the temperature reached by the top flange of the steel section. (Huang, Burgess, Plank, 1999) The degree of shear connection in the heated beam was assumed to be partial whilst the rest of the composite floor deck systems in the surrounding area were modelled as having full shear interaction. Analysis of the test results showed that the deflection at the mid-span of the heated beam increased with temperature. It was concluded from this that the assumption that partial interaction was corre

WHITE BLOOD CELLS Essay -- essays research papers fc

White Blood Cells Bacteria exist everywhere in the environment and have continuous access to the body through the mouth, nose and pores of skin. Further more, many cells age and die daily and their remains must be removed, this is where the white blood cell plays its role.   Ã‚  Ã‚  Ã‚  Ã‚  According to this quotation, without white blood cells, also known as leukocytes, we would not be able to survive. White blood cells are our body’s number one defense against infections. They help keep us clean from foreign bacteria that enter our bodies. Statistics show that there are five to ten thousand white blood cells per micro liter of blood, however this number will increase during an illness. White blood cells can differ in many ways, such as, size, shape and staining traits. There are five different kinds of white blood cells that fall into two separate categories. One category is called, granular leukocytes, and the other is called agranular white cells.   Ã‚  Ã‚  Ã‚  Ã‚  There are three different types of granular leukocytes. Neutrophil is a phagocyte, produced in the bone marrow that ingests and destroys bacteria extremely fast. Neutrophil has a diameter, which is, about ten to twelve micrometers long. They make up about 60-70 percent of the total number of white blood cells in our body. Eosinphil is a type of white blood cell that secretes poisonous materials in order to kill parasites, allergies and phagocytosis of bacteria, which is when the...

Polyhydroxybutyrate Phb

Polyhydroxybutyrate PHB Polyhydroxybutyrate (PHB) is a polyhydroxyalkanoate (PHA), a polymer belonging to the polyesters class. Progress Analysis: – Bacteria first used to make PHB in 1925 at Pastuer Institute in Paris. – In 1970’s adopted by Imperial Chemical Industries (ICI) – Alcaligenes Eutrophus grown in fermentation vats with Molasses – The bacteria is then starved of nutrients (glucose and nitrogen) – PHB is produced as an energy store for the bacteria. In 1980’s Maddison University (Virgina) successfully cloned the 3 genes of A. Eutrophus that control PHB production and transferred them to Escherichia coli – an easier bacteria to work with allowing easier manipulation of the polymer depended on the need. – In 1990’s the 3 genes were cloned into sugar beets and turnips – much larger scale production of polymer. Work continuing (with Monsanto – company bought patent) into cloning genes to corn. Production: The manufacturing process of PHB begins with sunlight.Through photosynthesis carbon dioxide from the atmosphere is converted to carbohydrates via sugar beets or sugar cane. These carbohydrates (like Lactose, Fructose and Glucose) are the raw material for the manufacturing of PHB. Uses: †¢In medicine, PHB is compatible with the blood and tissues of mammals. The monomer of PHB is a normal metabolic in the human blood. As the body reabsorbs PHB it might be used as a surgical implant, in surgery, as seam threads for the healing of wounds and blood vessels. In pharmacology, PHB can be used as microcapsules in therapy or as materials for cell and tablet packaging. †¢In packaging for deep drawing articles in the food industry, for example, bottles, laminated foils, fishnets, potted flower, hygiene, fast food, one-way cups, agricultural foils and fibres in textile. Advantages of PHB: †¢Good mechanical properties, especially when low density and price are taken int o account. †¢Recyclable, renewable and non-abrasive to manufacturing equipment. †¢PHB is hydrophobic, therefore protects natural ? res from moisture sensitivity. †¢Mechanical properties are comparable to other polymers used (e. g. PP). †¢PHB has a fast degradation rate compared to other plastics. (months in sewage and years in sea water) yet ultra violet light can speed up this process. †¢The main advantage in the medical field is that PHB is a biodegradable plastic which can be inserted into the human body and does not have to be removed again. †¢Can be manipulated genically therefore can be used for many things Disadvantages of PHB: †¢It has a tendency to be brittle. Costs four times as much as polyethylene (it’s major competitor) †¢Cheaper to produce necessary materials from petrochemical industry. †¢Large scale production in early stages. †¢Uses sugarcane which can decrease biodiversity such as in Brazil. Evaluative Conclu sion: PHB has huge potetial as polymer for future,this is due to its main advantages such as being biodegradable and it has an ease of manipulation. This is good although work must be done to make it cheaper. Also work must be done to reduce the very large scale production in the early stages of production.There needs to be a way to make this plastic from cellulose in plant cell walls rather than from sugarcane alone. As the petrochemical industry supplies become scarce the price of PHB will go down, which is good for future use.

South AFrican anthem essays

South AFrican anthem essays Choose one song that for you that epitomizes South African Music. Nkosi sikelela, thina lusapho lwayo. O se boloke, O se boloke setjhaba sa heso, Setjhaba sa South Afrika - South Afrika. Nkosi Sikelel' iAfrika was composed in 1897 by Enoch Mankayi Sontonga , a teacher at a Methodist mission school in Johannesburg. It was one of many songs he composed, and he was apparently a keen singer who composed the songs for his pupils. The words of the first stanza were originally written in Xhosa as a hymn. In 1927 Samuel Mqhayi, a poet, later added seven additional Xhosa stanzas. Most of Sontonga 's songs were sad, witnessing the suffering of African people in Johannesburg, but they were popular and after his death in 1905 choirs used to borrow them from his wife. Solomon Plaatje, one of South Africa's greatest writers and a founding member of the ANC, was the first to have the song recorded. This was in London in 1923. A Sesotho version was published in 1942 by Moses Mphahlele.The Rev J L Dube's Ohlange Zulu Choir popularised Nkosi Sikelel' iAfrika at concerts in Johannesburg, and it became a popular church hymn that was also adopted as the anthem at political meetings. For decades it was regarded as the national anthem of South Afrika by the oppressed and it was always sung as an act of defiance against the apartheid regime. A proclamation issued by the State President on 20 April 1994 stipulated that both Nkosi Sikelel' iAfrika and Die Stem, The Call of South Africa, would be the national anthems of South Africa. In 1996 a shortened, combined version of the two anthems was released as the new National Anthem, Official Version.There are no standard versions or translations of Nkosi Sikelel' iAfrika so the words vary from place to place and from occasion to occasion. Generally the f ...

Bodily-Kinesthetic Intelligence Profile

Bodily-Kinesthetic Intelligence Profile Bodily-kinesthetic intelligence is one of Howard Gardners nine multiple intelligences. This intelligence involves how well an individual controls her body in terms of physical activity and/or fine motor skills. People who excel in this intelligence typically learn best by doing something physically as opposed to just reading and answering questions. Dancers, gymnasts, and athletes are among those that Gardner sees as having high kinesthetic intelligence. Background Gardner, a developmental psychologist  and Harvard University education professor, decades ago developed a theory that intelligence can be measured in many ways other than simple IQ tests. In his seminal 1983 book, Frames of Mind: The Theory of Multiple Intelligences  and his update, Multiple Intelligences: New Horizons, Gardner laid out the theory that paper-and-pencil IQ tests are not the best ways to measure intelligence, which can include spatial, interpersonal, existential, musical and, of course, bodily-kinesthetic intelligence.  Many students, however, do not perform to their best ability during pen and paper tests. While there are some students who function well in this environment, there are those who do not. Gardners theory unleashed a firestorm of controversy, with many in the scientific - and specifically psychological -community arguing that he was merely describing talents. Nevertheless, in the decades since he published his first book on the subject, Gardner has become a rock star in the education field, with literally thousands of schools taking up his theories. These theories are taught in nearly every education and teacher-certification program in the country. His theories have gained acceptance and popularity in education because they argue that all students can be smart or intelligent but in different ways. The Babe Ruth Theory Gardner  explained bodily-kinesthetic intelligence by describing the story of a young Babe Ruth. Ruth was playing catcher, although some accounts say he was just a spectator standing to the side, at St. Marys Industrial School for Boys in Baltimore. He was only 15 and laughing at a bumbling pitcher.  Brother Matthias Boutlier, a true mentor to Ruth, handed him the ball and asked if he thought he could do better. Of course, Ruth did. I felt a strange relationship between myself and that pitchers mound, Ruth later described in his autobiography. I felt, somehow, as if I had been born out there. Ruth, of course, went on to become one of sports historys greatest baseball players, and indeed, perhaps historys top athlete. Gardner argues that this kind of skill is not so much a talent as it is an intelligence. Control of bodily movement is localized in the motor cortex, Gardner says in Frames of Mind: The Theory of Multiple Intelligences, and  with each hemisphere dominant or controlling bodily movements. The evolution of body movements is an obvious advantage in the human species, suggested Gardner. This evolution follows a clear developmental schedule in children, is universal across cultures and thus satisfies the requirements of being considered an intelligence, he says. People Who Have  Kinesthetic Intelligence Gardners theory can be connected to differentiation in the classroom. In differentiation, teachers are encouraged to use different methods (audio, visual, tactile, etc)  to teach a concept. Using a variety of strategies is a challenge for educators who use different exercises and activities in order to find ways a student will learning a topic. Gardner defines intelligence as an ability to solve problems.  But, whatever you call it, certain types of people have a great intelligence or ability in the bodily-kinesthetic area, such as athletes, dancers, gymnasts, surgeons, sculptors, and carpenters. Furthermore, famous people who have displayed a high level of this kind of intelligence include former NBA player Michael Jordan, the late pop singer Michael Jackson, professional golfer Tiger Woods, former NHL hockey star Wayne Gretzky and Olympic gymnast Mary Lou Retton. These are clearly individuals who have been able to do extraordinary physical feats. Educational Applications   Gardner and many educators and proponents of his theories say there are ways to foster the growth of kinesthetic intelligence in students by offering the following in the classroom: including role-play activitiesusing manipulativescreating learning centers having students create models when appropriateacting out literature or readingsmaking a video presentation for the class All of these things require movement, rather than sitting at a desk and writing notes or taking paper-and-pencil tests. Conclusion Gardners bodily-kinesthetic intelligence theory says that even students who do not ace paper-and-pencil tests can still be considered intelligent. Athletes, dancers, football players, artists, and others can learn effectively in the classroom if teachers recognize their physical intelligence. Differentiating instruction for bodily-kinesthetic learners offers an effective means to reach these students who may well have bright futures in professions that require a talent for controlling body movements. Other students will benefit from the use of movement as well.

English - Essay Example They were forced to stop all import and export of armament and to relinquish land resources. The economical ramifications were harsh. The war reparations were excessively high and would have been to the equivalent of $385 billion dollars in today's economy. They were only paid off last year but the final payment was supposed to have been paid in 1988. Politically, Germany was forced to relinquish its colonies and European provinces. The treaty was not accepted as it was considered as a "Diktat" of a sign of Guilt. It was eventually signed in 1919. The existing government resigned and the Weimer Republic was established. Nationalistic tendencies were alight as "those who had not supported the war had agreed to the signing of the treaty" (members of the Weimer Republic, Jews, Communists, and Socialists) Having been the most impacted by the Treaty, the Germans did not like the results because they felt it dealt too harshly with Germany and they had expected leniency thanks to Woodrow Wi lson's Fourteen Points. The treaty forced them to give up some of their most valued land resources, people, and money. Since German leaders were not allowed to participate in the treaty conference, and because they refused to sign and new leaders were put into place that would sign the treaty, Germans felt as if the treaty was imposed upon them. There were also many German's who refused to believe that the German military had actually been defeated. They saw no sign of an invasion of Germany so in turn believed that Germany had not lost the war.

History of Management Coursework Example | Topics and Well Written Essays - 1250 words

History of Management - Coursework Example Some of the known theorists whose theory’s themes are still in use now are Fredrick Taylor, Henri Fayol and Max Weber. They developed scientific management theory, modern operational-management theory and bureaucratic theory respectively. Managers use the ideas in the theories to run their duties and perform the organizations' activities to achieve their objectives. For example, many managers use the ideas to coordinate their workers, organize their plans, administer worker’s payments and employ skilled workers to achieve the company objectives. Frederick Taylor developed the scientific management theory in the 1880s and 1890s in the manufacturing industries. Scientific management is a management theory that synthesis and analyzes workflows. Its major objective is improving the efficiency of economics, mostly the labour productivity. It among the earliest attempts to use science in management and engineering processes. It needs a high-level managerial control of employe e practices on their work and entails a high managerial workers ratio to labourers than the prior management periods (Frederick, 2007). The theory evolved in an era when automation and mechanization were infancies. The methods and ideas of the theory extended to the American manufacturing system in the craft transformation in automation and mechanization. Therefore, the over labour-displacing technologies concerns rose with the increase of automation and mechanization (Frederick, 2007). Hence, the theory influences some of the management strategies in today’s industries. The theory guide on the worker’s payment. Fredrick studied that some employees were more talented compared to others, and the smart ones were mostly unmotivated. He also observed that many employees that got forced to work repetitive jobs tend to work at a slower rate that is unpunished.

To what extent can a measure of national income (GDP) Essay

To what extent can a measure of national income (GDP) - Essay Example Keywords: GDP, welfare, happiness, economy, wealth. GDP as a Measure of Happiness and Welfare Gross Domestic Product is a value of all the final goods and services that are produced in domestic territory of an economy, within a single accounting year. This is used as a measurement for finding out the different levels of growth in an economy. Not only that, but the GDP is used to compare the growth and development of one economy with another as well. However, with time, many economists have begun trying to find out the happiness index faced by the citizens of a country, with the help of the GDP. However, they fail to pose the following questions; what is the relationship between GDP and welfare? Can GDP be regarded as a good index of welfare among the people of a country? Or is it simply a measure for finding out the kind of growth and development the economy has undergone, not taking into account the actual distribution of wealth? While looking at the figures of per capita income and national income of a country on the whole, one may find that the country is prospering very well and has achieved growing levels of independency when it comes to its market segments and trade related areas. The country might be doing really well in almost all fields – right from the primary to the tertiary sector. But just because something looks good from the outside, it cannot be judged inside as well, can it? In simple terms, the capacity to purchase goods and services is what makes people feel satisfied. However, this capacity or purchasing power is available to the people of a nation on the basis of their incomes. If they have low incomes, then they are able to afford lesser and vice versa. The happiness index of a person thus, depends on the kind of satisfaction he is able to achieve, which in turn, as discussed above, is a direct reaction to the level of income earned by him. In this case, the GDP cannot be measured in terms of the number of goods and services sold in an economy in a year, but by the level of distribution of income within the country which in turn affects the number of goods and services purchased by different sections of society within a year. Therefore, the use of goods and services by different people in an economy is what contributes to their well being, and not just the GDP alone. The greater the magnitude of the GDP, the greater the welfare of the people, was what was earlier believed by most economists. However, with more development and consumerism all around the world, with people having higher power and choices in order to utilize resources to satisfy their needs and wants, the GDP itself poses very stark limitations to the kind of measurement it can hope to provide to measuring an index of welfare of the nation. (Osberg, Lars and Sharpe, Andrew) In order to understand this argument better, one needs to delve into the levels of distribution of income within a nation or an economy. The distribution of wealth is not unif orm in most economies, may they be developed or developing ones. There is always a clear demarcation between the haves and the have not’

Deconstruction Essay Example | Topics and Well Written Essays - 1250 words

Deconstruction - Essay Example Allan Poe was born in in 1809, in Boston. His father was called David Poe while the mother was Elizabeth Arnold Hopkins. He lost his parents before he was three, and he had to move to Virginia to live with a wealthy tradesman called John Allan. John took Poe as one of his sons. Poe went to private school and conflicts occurred between him and his guardians when he decided to pursue literary works. He attended university of Virginia, but his dropped after the first year. He had gambling debts and his guardians refused to settle the debts. He joined the army and became sergeant major. He later quit the army. He wrote many literary works. He wrote many poems when he was in West point. His life became miserable when he became a heavy drinker and smoker. He went through many problems in his live that helped him write many poems. His nature of being a heavy drinker is even realized in â€Å"The Cask of Amontillado†. His literary talent would not have been that interesting if were no t the way his behavior and character influenced his writing. His love for alcohol helped him incorporating the abuse of alcohol in his work. A clear evidenced in â€Å"The Cask of Amontillado†, where he used Fortunato show the effects of heavy drinking in the society. The names that have been used in Poe’s work have some hidden meaning. ... The name sherry could be used to mean a titular amontillado. Therefore, in Italian, it represents a Montilla wine. Therefore, there is a â€Å"relationship between the way amontillado is produced and the way Montresor is using Fortunato† (Lewis, 179). Theory of deconstruction is further illustrated trough names used on the Poe’s work and some activities that are taking place. Meanings of the names that are used are related to the activities that take place in this literary work. One of the related activities includes the way Montresor is treating Fortunato and the process that is involved during the production of Montilla wine. â€Å"Montilla wine is manufactured by allowing yeast to grow in a pipe. This yeast can only grow under certain conditions. These conditions include leaving two spaces open on the cask that is used. The wine should be protected from oxygen in order to allow fermentation to take place. If oxygen is allowed to have contact with the yeast, the wine will not be produced with the required standards. This entire process should result in production of sweet wine† (Lewis, 181). This process of manufacturing mantilla wine is directly related to the process that Montresor uses in revenging on Fortunato. Montresor views Fortunato as his sweet pretender who has been induced by alcohol. Montresor’s behavior seems to be sweet to Fortunato. This is because his behavior has been induced with alcohol and he not able to realize Montresor’s intention. Montresor enjoys the alcohol effect on Fortunato since he knows he (Montresor) is going to achieve his goal. The alcohol content in Fortunato’s body prevents him from refining himself. Another contradiction in the story comes out when the

A survey of student attitudes to university fees Essay

A survey of student attitudes to university fees - Essay Example Example include Market Research Surveys Government Surveys Public Health Surveys Public Opinion Polls Censuses may be another example of quantative research. Although a census does not include a sample/portion of the community, it surely does include many others modern survey methodological aspects such as interviewers and questionnaires. Surveys are an important tool for research. With the help of surveys we may be able to gather precious information not only for research purposes but also for public information. Surveys are not restricted to one field or line of information. Information may be gathered for marketing, sociological, psychological and many other aspects and fields of study (Advanced Research Seminar On Cognitive Aspects Of Survey Methodology & Jabine, 1984). A survey was conducted regarding tuition fees and related issues. Most of the respondents were international which were paying a comparatively high tuition fees. As expected, all of them were of the idea that the tuition fees were high and should be cut down. A few students were happy with their fees but it is believed this was due to the fact that they were either UK home students or EU students. Furthermore, it was highlighted that most of the international students relied on their parents to pay their tuitions fees while a few were dependent on student loans. 80% of the respondents believed that the tuitions fees of UK was considerably higher than their home countries. This may have been said to be due to different economic conditions and foreign exchange risk between the two countries but with 65% respondents claiming the tuitions fees to be considerably more, is a matter to be looked into. Respondents also claimed that such huge tuitions fees is a cause of distress for their parents back home. Few even went on saying that their family could not afford the tuition fees but still managed sending them abroad to study and obtain a degree. The students responding were usually from developing nations which have a bad economic condition as compared to that of UK. They also higlighted that if a parent is to spend so much on one siblings the rest may have to suffer and sacrifice their standard of education. The main reason cited for getting a degree was for the purposes of a job with some respondents thought to be confused of their basis of studying at a university. Nearly all of the students were of the view that the government should be paying for their tuitions fees and ensure that no financial stress and constraint should take place while studying. Respondents also were of the idea that at least some part of the fees if not all should be paid by the government. The recent floating idea of an increase in tuition fees is a prime ongoing debate. It was believed that tuition fees shall be increase further (BBC News, 2012.) After the previous tuition fees rise Parents believe that supporting one of the children had been financially tough and an increase shall only and only increase their burden. Furthermore, parents feared that their children shall be facing huge debts if they plan to obtain a degree. Many students were also of the view that they shall be put off with higher tuition fees (BBC News, 2010). Ttihe increase in tuition fees also witnessed many protests and strikes with students even been arrested (the Guardian,

Deconstruction Essay Example | Topics and Well Written Essays - 1250 words

Deconstruction - Essay Example Allan Poe was born in in 1809, in Boston. His father was called David Poe while the mother was Elizabeth Arnold Hopkins. He lost his parents before he was three, and he had to move to Virginia to live with a wealthy tradesman called John Allan. John took Poe as one of his sons. Poe went to private school and conflicts occurred between him and his guardians when he decided to pursue literary works. He attended university of Virginia, but his dropped after the first year. He had gambling debts and his guardians refused to settle the debts. He joined the army and became sergeant major. He later quit the army. He wrote many literary works. He wrote many poems when he was in West point. His life became miserable when he became a heavy drinker and smoker. He went through many problems in his live that helped him write many poems. His nature of being a heavy drinker is even realized in â€Å"The Cask of Amontillado†. His literary talent would not have been that interesting if were no t the way his behavior and character influenced his writing. His love for alcohol helped him incorporating the abuse of alcohol in his work. A clear evidenced in â€Å"The Cask of Amontillado†, where he used Fortunato show the effects of heavy drinking in the society. The names that have been used in Poe’s work have some hidden meaning. ... The name sherry could be used to mean a titular amontillado. Therefore, in Italian, it represents a Montilla wine. Therefore, there is a â€Å"relationship between the way amontillado is produced and the way Montresor is using Fortunato† (Lewis, 179). Theory of deconstruction is further illustrated trough names used on the Poe’s work and some activities that are taking place. Meanings of the names that are used are related to the activities that take place in this literary work. One of the related activities includes the way Montresor is treating Fortunato and the process that is involved during the production of Montilla wine. â€Å"Montilla wine is manufactured by allowing yeast to grow in a pipe. This yeast can only grow under certain conditions. These conditions include leaving two spaces open on the cask that is used. The wine should be protected from oxygen in order to allow fermentation to take place. If oxygen is allowed to have contact with the yeast, the wine will not be produced with the required standards. This entire process should result in production of sweet wine† (Lewis, 181). This process of manufacturing mantilla wine is directly related to the process that Montresor uses in revenging on Fortunato. Montresor views Fortunato as his sweet pretender who has been induced by alcohol. Montresor’s behavior seems to be sweet to Fortunato. This is because his behavior has been induced with alcohol and he not able to realize Montresor’s intention. Montresor enjoys the alcohol effect on Fortunato since he knows he (Montresor) is going to achieve his goal. The alcohol content in Fortunato’s body prevents him from refining himself. Another contradiction in the story comes out when the

The NASCAR Market Essay Example for Free

The NASCAR Market Essay I love to watch NASCAR (National Association of Stock Car Racing) races on television.  Ã‚   The action is fast paced and the thrill and anticipation, the waiting for the next crash is addictive.   Although sporting events are great venues for advertising, NASCAR events are pure marketing heaven. If you ever watch one and analyze the production, you can not miss the fact that even the cars themselves are commercials that compel you to stare at brand names of products every second. Car related industries profit greatly by paid commercial breaks in television programming and â€Å"on car† endorsements.    This type of on car advertising is ideal for the racing circuit, effectively presenting a product advertisement that is clearly seen and focused upon throughout the entire racing event. In his article, Dale Zooms to the front of the endorsements, Bruce Horovitz writes that since the drivers themselves are the stars, driver endorsements actually pay them more than winning the races.   He also says that marketing sales jumped from $50 million in 1990 to $2 billion in 2003.   With these statistics in mind, marketing research is essential in order to present a product, at a sellable price to a demographically correct market. Chris Jones states in his article, NASCAR Sponsors: Drive-By Marketing that â€Å"on car† advertising is viewed as a sure thing with guaranteed return of investment since 189 million households viewed televised NASCAR Winston Cup series races in 2003, advertisers can count on both high exposure as well as a wide geographic range of that exposure. Since these racing are so saturated with advertising and marketing, right down to cars being identified by their sponsors (i.e. the NAPA car), and the target audience is usually the male American blue collar worker, scheduling of the race days are usually planned and televised on weekends, with the sponsors in mind. With over $50 million in marketing sales being seen per year due to NASCAR sporting events, it is a certainty that the four P’s (product, pricing, place and promotion) are being utilized better in the NASCAR arena better than just any other venue today.

Contrasting And Comparing Mass Society With Popular Culture Media Essay

Contrasting And Comparing Mass Society With Popular Culture Media Essay When studying mass society and popular culture it is evident that there is a connection between the two theories. Yet, both also consist of two different perspectives in the relationship between media and its audiences. Popular culture, also known as pop culture, is a modern day standard of living life and items that are well recognized and usually accepted by our society today. On the other hand mass society is a society which possesses a mass culture and large-scale, distant, social institutions. The theories of mass society and popular culture provide two distinct perspectives on the relationship between media and the audience. However, in modern civilization it is mass society that dominates and is more applicable in todays society. Sub Topics: What is mass society? What is popular culture? Mass society and the audience. Popular culture and the audience. Proof that mass society is more applicable in todays society. Conclusion. Paragraph 1: When attempting to grasp the theory of mass society it is important to know that mass society is a theoretical perspective which is most popularly defined as a passive and manipulative form which possesses a mass culture and a number of people in modern day society. In other words mass society is a theory that draws together the work of various classical social theorists, as well as behavior scientists. Unlike popular culture, in a mass society people are manipulated into feeling the need to buy what there being sold, by the media, for personal needs. Individuals are seen as rootless not treated or valued on the basis of their individual qualities but bound together by needs rather than tradition (Kevin Williams Pg.25). Overall it is the mass society theory that has encouraged a view of the effects of the media on peoples lives and behaviors as straight forward and unmistakable. Paragraph 2: Similar to the majority of things that form a big part of our daily lives, popular culture is familiar and obvious. Popular culture, also referred to as pop culture, by definition consists of the traditional practices and beliefs or way of living life. It is in fact a collection of practices society follows in their everyday life. Popular culture consists of two very important words that help define its purpose and meaning a little better; the words popular and culture. Popular is the word used to define something that is liked by many individuals and the majority. An example of this would be the show The Jersey Shore. A television program that has been ranked by its viewers and MTV live, as the number one show that teenagers watched when it was aired. Making the show what is defined as something popular. The word culture on the other hand, has two definitions to it. One being the artistically perspective and cultural sense, and the other definition is an understanding that culture i s a form of living life and what can differentiate between our social and ethnic groups. Although these two definitions are the most common to culture, there are still other definitions applied to it. Another for example is; the social production and reproduction of sense, meaning and consciousness, the sphere of meaning which unifies the spheres of production (economics) and social relations (politics). (OBrian. p.5). This is merely an example, because of the many definitions that can be given to culture, of how diverse even the term culture itself is. From the two terms popular and culture springs the theory of Popular Culture, which is an acceptable way of consuming and producing and living life freely. Paragraph 3: As stated previously, the mass society theory is known to have a way with its audience. Threw the theory of mass media, the media is known to be passive and manipulative with the audience. The media manipulates its audience to desire and consume whatever it is they are attempting to sell and produce. Although many sociologists would go against this belief that the media does has a direct effect and sense of control on their audience, the constant growth rate and vast amount of money that corporations gain today says the contrary. In modern times, society is filled with constant advertisements that corporations produce so that their products will be purchased and used by individuals. Aside from the vast amount of advertisements on television society is also surrounded by more advertisements outside of the television, such as magazines and billboards. The question still arises; if the media does not have an influence on its audience why is it that so much money is being put into advert ising? (Kevin Williams, Pg. 165). It is evident that the media does in fact have a huge impact on society today. Paragraph 4: When looking at popular culture and the audience it can be argued that unlike mass society, popular culture is not primarily about consuming and production. Popular culture is not just a business it is also a lifestyle and unlike mass society it gives society the choice and freedom to choose what they do and do not want to consume. For example; when different trends are born individuals are given the option to follow these trends or to chose a different trend that they feel will show there personality better. Even with foods and life styles pop culture will vary. It is a choice and a way of living that is constantly changing throughout time. Paragraph 5: In todays culture it is obvious that mass society does dominate. The purpose to sell and suck the audience into the products is becoming harder to resist. Individuals are being manipulated from a very young age by the numerous amounts of corporations and advertisements surrounding them in their everyday lives. James Steyer, the author of the book The Other Parent, writes the following in his book; Its pretty clear that the goal of this multinational, sophisticated marketing scheme is not to benefit young children who shouldnt be watching a lot of TV anyways but to sell and enrich the network, manufacturers, and producers. (Steyer, Pg.98). This is the case in present times as mass society has their way with its victims. James Steyer later states that the target of these huge, manipulative campaigns are children of all ages, like his two year old daughter Carly. The aim was to encourage her attachment to the TV characters so that shed ask for the licensed products(Steyer. Pg.98). Pro ving just how the theory of mass society is dominating more and more each day. Once children gain the emotional attachment to the TV persona, companies will use that attachment to sell and produce products that the audience feels a connection with so that they can sell through them. Conclusion and Restate Thesis: Overall, the when comparing and contrasting the two theories of mass society and popular culture one can acknowledge that although both are two businesses, they are two different perspectives on mass media and society. Attempting to grasp an understanding of how the mass society works and has come to be known as passive and manipulative requires a lot of over viewing. The theories of mass society and popular culture provide two distinct perspectives on the relationship between media and the audience. However, in modern civilization it is mass society that dominates and is more applicable in todays society.

Walt Disney :: essays research papers

Walt Disney   Ã‚  Ã‚  Ã‚  Ã‚  Walt Disney was one of the famous motion-picture producers in history. He first became known in the 1920's and 1930's for creating such cartoon film characters as Mickey Mouse and Donald Duck. He later produced feature length cartoon films, movies about wild animals in their natural surroundings, and films starring human actors. Disney won 32 Academy Awards for his movies and for scientific and technical contributions to filmmaking. He also gained fame for his development of theme parks.   Ã‚  Ã‚  Ã‚  Ã‚  Walter Elias Disney was born on Dec. 5, 1901, in Chicago, Illinois. His family moved to Missouri, and he spent much of his boyhood on a farm near Marceline. At the age of 16, Disney studied art in Chicago. In 1920, he joined the Kansas City Film Ad Company, where he helped make cartoon advertisements to be shown in movie theaters.   Ã‚  Ã‚  Ã‚  Ã‚  In 1923, Disney moved to Los Angeles to become a film producer or director. When he failed to find a job, he returned to producing cartoons. He set up his first studio in the back half of a real estate office. For several years, Disney stuggled to pay his expenses. He gained success in 1928, when he released the first short cartoons that featured Mickey Mouse. Earlier filmmakers had found that animals were easier to animate than people. Mickey Mouse, drawn with a series of circles, proved ideal for animation.   Ã‚  Ã‚  Ã‚  Ã‚  In 1927, sound that had been added to motion pictures, and a process for making movies in color was developed a few years later. Disney and his staff made imaginative use of sound and color. Disney himself provided Mickey Mouse's voice for Steamboat Willie (1928), the first cartoon to use synchronized sound. His cartoon Flowers and Trees (1932) was the first cartoon in full Technicolor.   Ã‚  Ã‚  Ã‚  Ã‚  From 1929 to 1939, Disney produced a cartoon series called Silly Symphonies, which played in theaters along with other animated films featuring Mickey Mouse and other characters, like Donald Duck, Goofy, and Pluto. After 1924, Disney actually did more of the drawing necessary for his animated films. His genius lay in creating, organizing, and directing the films.   Ã‚  Ã‚  Ã‚  Ã‚  In 1937, Disney issued the first full-length animated feature film to be produced by a studio, Snow White and the Seven Dwarfs. It became one of the most popular movies in history. Disney's later full-length animated films included Pinocchio (1940), Fantasia (1940), Dumbo (1941), Bambi (1942), Cinderella (1950), Alice in Wonderland (1951), Peter Pan (1953), Lady and the Tramp (1955), Sleeping Beauty (1959), 101 Dalmations (1961), and the Jungle Book (released in 1967, after his death). In 1950, Disney released Treasure Island, his first full-length movie to use only human actors.

Dairy Products :: Nutrition, Proteins, Vitamins, Minerals

Milk is an excellent dietary source of high-quality protein vitamins and minerals. Dairy products like cheese also are an important part of a well balanced diet Cheese is contain of the same basic materials found in milk, but in the form concentration. Include casein, fat, some vitamins , soluble and insoluble salts. Soy bean protein is a popular food ingredient used throughout the world for its nutritional and functional properties, especially after the FDA in the United States allowed a soy health claim in 1999(Fukushima, 2001). This claim has sparked the development of new soy foods (Zhong, Wang, Xu, & Shoemaker, 2007).The traditional product coagulation of soy proteins has also been considered a way of producing soy protein gels, The milky white floid obtained from soybean by soaking ,grinding and filtering is called soymilk.(A.A. Gatade, and, & Sahoo, 2009)Soymilk contains some major and minor components like protein ,fat, carbohydrate ,calcium ,iron, sodium, carotene, vitam in-E, and riboflavin(A.A. Gatade, et al., 2009). The soymilk is used in many products like yogurt, cheese, etc.(Wang, Xiong, & Wang, 2001). Uses of animal rennet became limited for religious reasons .Most of Muslim people consider that cheese is produced by an enzyme which comes from an animal and slaughtered on the non Islamic way no halaal. And also soybean cheese for vegetarian people who did not eat animal product .. Calf rennet which prepared and obtained from the fourth stomach of calves sucking (Nagodawithana & Reed, 1993) one of the important enzymes is traditionally used for cheese making all over the world . Since 1960s. the production of cheese increase considerably and number of cattle decrease this caused lessen in rennin. Owing to the rapid growth and the relative inexpensive growth substrate the microbial rennet like milk-clotting enzyme (MCE) proteinase is very important in dairy technology has become a popular rennet substitute.(Pei, Yu, & Chou, 2005).Proteinase is capable of cleaving protein into peptides and amino acids, they are characterized by their optimal pH (acid, neutral or alkaline), their temperature, their ability to hydrolyze specific proteins (Law,1999). Milk coagulation is the basic step in cheese manufacturing. Milk clotting enzymes are the primary active agents in cheese making, which involves the enzyme-mediated cleavage of kappa-casein which covering the protein micelles at the peptide bond Phe 105-Met 106 that renders the casein micelles unstable and eventually causes aggregation that yields a clot or a gel.

Nathaniel Hawthorne’s as Anti-Transcendentalist Essay

Nathaniel Hawthorne an American romantic writer, whose literature is known for its Anti-Transcendentalism, wrote Young Goodman Brown and The Scarlet Letter. Nathaniel Hawthorne is a writer during the American Romantics, where the majority of writing is focused on nature, supernatural elements; one’s psychology and the criticism of society’s â€Å"norm†. Nathaniel is Hawthorne known for his notorious Anti-Transcendentalist literature. Anti-Transcendentalism ideals are about one’s evil and inner and sinful nature, where everyone is born evil and no matter what, and that humanity is evil and destructive. Hawthorne is not able to accept the optimism of the Transcendentalists and through his writing he tries to look for truths in one’s heart and mind. Hawthorne’s use of symbols, characters, and themes in his literature classify his writings as Anti-Transcendentalist.Through the use of character development Hawthorne’s literature can be clas sified as Anti-Transcendentalist. In both pieces of literature Hawthorne uses characters who act as the epitome of Anti-Transcendentalism. The Scarlet Letter has two imperative characters that exemplify Anti-Transcendentalist. First we have Dimmesdale; he is a minister in the town and is one of the most highly respected men in Boston. In reality Dimmesdale is a sinner and an adulterer as he slept with Hester, another man’s wife and got her pregnant. Hester’s punishment for her actions are; public humiliation, and the Scarlet Letter. Though Dimmesdale is not revealed as her accomplice over time he himself grows a Scarlet Letter of his own. â€Å"Most of the spectators testified to having seen, on the breast of the unhappy minister, a Scarlet Letter†¦Mr. Dimmesdale, on the very day when Hester Prynne first wore her ignominious badge, had begun a course of penance†(SL 211). When Hawthorne reveals Dimmesdale having a Scarlet Letter it expresses the ideals of Anti-Transcendentalism where his own Scarlet Letter is the example of one’s inner darkness and evil that is inside of him. In Young Goodman Brown after Goodman Brown witnesses all of the townspeople participating in a witchcraft ceremony and comes back to his home he sees the world in a new perspective. â€Å"The next morning Goodman Brown came slowly into the streets of Salem staring around him like a bewildered man†(YGB 7). He is never the same and trusts no one, including his wife. It says that he snatched away the children that Goody Cloyse was talking to and when his wife embraced him he just walked away.(YGB 7 )Hawthorne uses Goodman Brown to show that everyone is evil inside and that he human spirit is destructive. Character development acknowledges a role in how Hawthorne’s literature should be classified as Anti-Transcendentalist.Character Development is not the only factor that classifies Hawthorne’s literature as Anti-Transcendentalist; symbols take on an enormous role as well. In the Scarlet Letter two symbols are Pearl, and the actual Scarlet Letter. Pearl is not only a peculiar child for her age she has a much deeper meaning. Pearl is Hester’s living example of her sin. Pearl’s purpose in the Scarlet Letter is to represent sin, but not only to Hester but in the world as well. The Actual Scarlet Letter is also a symbol which represents not only sin, but the Anti-Transcendentalist idea that your sins will never go away, sin will remain evident inside you and around you. These two examples could not exemplify Anti-Transcendentalist beliefs any more as its primary focus is about sinfulness and how people view sin. In Young Goodman Brown a few symbols that embody Anti-Transcendentalism are the forest and the old man who is meant to be the devil. The forest in both of Hawthorne’s literature has a dark meaning towards it and also is a place where no good can happen Goodman Brown believes that the devil could be present in the forest, and when he sees a woman from his town he hides as he is ashamed to be walking in the forest. The forest is characterized as devilish, frightening, and dark. The old man is also a symbol which is portrayed as the devil. He is used to represent the destructiveness of the human spirit and to show the evil within humanity. All of these characteristics contribute to classify Hawthorne’s writing as Anti-Transcendentalist. Aside from characters and symbols Hawthorne uses themes in his literature which contribute to classifying his writings as Anti-Transcendentalist. The most prominent theme in both pieces of his literature is the, nature of evil in humanity. The Scarlet Letter uses the â€Å"Black Man† as an alter ego to Chillingworth who is a representation for the Devil. On the outside Chillingworth is a doctor who is supposed to help people when they are sick but inside he is evil. Instead of giving Dimmesdale life he is making him sick, as he is taking life and making it miserable. â€Å"‘Come away, or yonder old black man will catch you! He hath got hold of the minister already. Come away, mother or he will catch you!’†(SL 61) The quote is from Pearl who understands Chillingworth is the devil and has already captured and made Dimmesdale’s life horrible. Another instance of the evil in humanity partakes in the Story of Young Goodman Brown where it contains a greate r depth of evil in humanity. The Scarlet Letter is only one man consumed by the devil but in Young Goodman Brown the whole town appears to be taking part in a witchcraft ceremony. When he is taken into the forest he sees the minister, a deacon and many more respected men of his town are evil. â€Å"He recognized a score of church members of Salem†¦Good old Deacon Gookin had arrived, his reserved pastor†(YGB 6) These men and women who are highly respected are taking part in English witchcraft. Hawthorne is expressing that humans are capable of inner darkness and evil, which enable his literature to be classified as Anti-Transcendentalist. Symbols, characters, and themes are the elements that Hawthorne uses to show how his literature can be classified as Anti-Transcendentalist. The symbols in both pieces of Hawthorne’s literature represent sin, and evil, both which are qualities of Anti-Transcendentalism. All the characters in Hawthorne’s literature contain evidence of sinful nature, inner darkness and the destructiveness of the human spirit. These qualities are most prominent in Chillingworth and Dimmesdale and especially with Goodman Brown. Lastly Hawthorne’s primary theme in all his literature is the nature of evil in humanity. Chillingworth exemplifies this theme greatly as well as the towns’ people in Young Goodman Brown. The way Hawthorne writes and his use of symbols, themes, and characters classify his writing as Anti-Transcendentalist.
