Computer benefits Essay

In today’s modern world, computers are needed everyday. Around the world, children use computers from the time they are little. It’s true that children should have fun when they are young; however, in my opinion, a child who knows how to use the computer will be more successful in the future. My reasons for this view are personal, academic and professional. From a personal point of view, computers can help young people to learn more about the world. For example, some children use the Internet to find information on different subjects. In this way, they learn to find answers by themselves. By using the computer when they are little, children feel more comfortable around computers. They also know how to use the computer for different reasons. From an academic viewpoint, children have to learn how to use this new invention. For instance, when I was in college, many students used to bring their laptops to class. They used to take notes, do research and share information. They wrote their essays, made presentations and created useful lists. Children who can use the computer when they are young have more confidence than other children. From a professional perspective, the computer is found in every kind of office. Today, employers will still hire people who cannot use computers and give them computer training. But tomorrow, companies will expect people to have these skills already. As a result, by encouraging children to use the computer for a short time every day, parents are preparing their children for future jobs. In conclusion, it is clear that computers are now a part of our regular life. Children who can use computers easily and confidently will do better in the future.

Temperature (Celsius and Fahrenheit)

is equal to . Similarly,   is equal to . Therefore, conversion of Celsius to Fahrenheit Formula can be written as: F = mC + a Since at   the value is , therefore a = 32. and 212 = m100+32à   m = 180/100 = 9/5 Therefore, formula to convert Celsius to Fahrenheit is: F = (C x 9/5) + 32 Rearranging F and C give formula to convert Fahrenheit to Celsius: C = (F – 32) x 5/9 Both equations are useful for conversion of Celsius to Fahrenheit and Fahrenheit to Celsius. If we know the value of temperature in degree Fahrenheit and want to calculate value in degree Celsius than equation C = (F – 32) x 5/9 can be used. Similarly, if we know the value of temperature in degree Celsius and want to calculate value in degree Fahrenheit than equation C = (F – 32) x 5/9 can be used F = (C x 9/5) + 32. The city picked for finding its record high temperature and record low temperature is London. The record high temperature ((June, July and August)) and record low temperature (December) is given below in degree Celsius. Record High Temperature: 32 Record Low Temperature:   -17 Converting, record high temperature and record low temperature from degree Celsius to degree Fahrenheit. Record High Temperature: F = (C x 9/5) + 32 = (32 x 9/5) + 32 = 89.6 Record Low Temperature:   F = (C x 9/5) + 32 = (-17 x 9/5) + 32 = 1.4 Reference: http://www.fordhamprep.org/gcurran/sho/sho/lessons/lesson29.htm   Accessed on November 22, 2007 http://www.myforecast.com/bin/climate.m?city=60876&metric=true Accessed on November 22, 2007

CONCLUSION CHAPTER-1 INTRODUCTIONThe Diagrids are perimeter structural configurations characterized by a narrow grid of diagonal members which are involved both in gravity and in lateral load resistance. Diagonalized applications of structural steel members for providing efficient solutions both in terms of strength and stiffness are not   new ,however nowadays a renewed interest in and a widespread application of diagrid is registered with reference to large span and high rise buildings, particularly when they are characterized by complex geometries and curved shapes, sometimes by completely free forms.Compared to conventional orthogonal structures for tall buildings such as framed tubes, diagrid structures carry lateral wind loads much more efficiently by their diagonal members’ axial action. ;   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Among the large-span buildings some examples are represented by the Seatlle Library, the London City Hall, the One Shelley Street in Sydney, and more recently by several outstanding Pavilions realized at the Shanghai 2010 Expo, (e. g. France, UAE) as well as by some dazzling projects like the Astana National library.Among tall buildings, noteworthy examples are the Swiss Re building in London, the Hearst tower in New York, the CCTV headquarters building in Beijing, the Mode Gakuen Spiral Tower in Aichi, the Cyclone Tower in Asan, the West tower in Guangzhou, the Lotte super tower in Seoul, the Capital Gate in Abu Dhabi, the Bow project in Calgary, the Building of Qatar Ministry of Foreign Affairs in Doha. .  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     The diagrid systems are the evolution of braced tube structures, since the erimeter configuration sti ll holds for preserving the maximum bending resistance and rigidity, while, with respect to the braced tube, the mega-diagonal members are diffusely spread over the facade, giving rise to closely spaced diagonal elements and allowing for the complete elimination of the conventional vertical columns. Therefore the diagonal members in diagrid structures act both as inclined columns and as bracing elements, and carry gravity loads as well as lateral forces due to their triangulated configuration, mainly internal axial forces arise in the members, thus minimizing shear racking effects.To begin with the behavior of basic Diagrid   Ã‚  module is   Ã‚  discussed, followed by construction process. Then the merits and demerits of   Diagrids are listed. CHAPTER-2 THE TRIANGULAR DIAGRID MODULE 2. 1  Ã‚  Ã‚  INTRODUCTION Diagrid structure is modeled as a beam, and subdivided longitudinally into modules according to this repetitive diagonal pattern. Each Diagrid module is defined by a si ngle level of diagonals that extend over ‘n’ stories. | Figure 1: 8 storey Diagrid with 60 degree diagonal angle| 2. 2 MODULE GEOMETRYDiagrid structures, like all the tubular configurations, utilize the overall building plan dimension for counteracting overturning moment and providing flexural rigidity through axial action in the diagonals, which acts as inclined columns; however, this potential bending efficiency of tubular configuration is never fully achievable, due to shear deformations that arise in the building â€Å"webs†; with this regard, diagrid systems, which provide shear resistance and rigidity by means of axial action in the diagonal members, rather than bending moment in beams and columns, allows for a nearly full exploitation of the theoretical bending resistance. Being the diagrid a triangulated configuration of structural members, the geometry of the single module plays a major role in the internal axial force distribution, as well as in conferr ing global shear and bending rigidity to the building structure. While a module angle equal to 35 ° ensures the maximum shear rigidity to the diagrid system, the maximum engagement of diagonal members for bending stiffness corresponds to an angle value of 90 °, i. e. vertical columns.Thus in diagrid systems, where vertical columns are completely eliminated and both shear and bending stiffness must be provided by diagonals, a balance between this two conflicting requirements should be searched for defining the optimal angle of the diagrid module. Usually Isosceles triangular geometry is used. i. OPTIMAL ANGLE: As in the diagrids, diagonals carry both  shear and moment. Thus, the optimal angle of diagonals  is highly dependent upon the building height. Since the  optimal angle of the columns for maximum bending  rigidity is 90 degrees and that of the diagonals for  maximum shear rigidity is about 35 degrees, it is  expected that the optimal angle of diagonal members fo rdiagrid structures will fall between these angles and as  the building height increases, the optimal angle also  increases. Usually adopted range is 60 -70 degree. i. MODULE DIMENSIONS: ?  Ã‚  Ã‚  Height of the module:  Ã‚  It depends on the number of stories stacked per module. Usually 2 – 6 stories are stacked per diagrid with average floor height varying from 3. 5 -4. 15 m on an average. ?  Ã‚  Ã‚  Base of the module:  Ã‚  It depends on the height and optimal angle (apex angle) of the diagrid. CHAPTER-3 STRUCTURAL  Ã‚   ACTION OF A DIAGRID MODULE 3. 1  Ã‚  EFFECT OF GRAVITY LOADING The diagrid module under gravity loads G is subjected to a downward vertical force, NG,mod, causes the two diagonals being both in compression and the horizontal chord in tension. | Figure 2: Effect of Gravity Loading. | 3. 2  Ã‚  Ã‚  Ã‚  EFFECT OF LATERAL LOADINGUnder horizontal load W, the overturning moment MW causes vertical forces in the apex joint of The diagrid modules, NW,mod, with direction and intensity of this force depending on the position of the Diagrid module, with upward / downward direction and maximum intensity in modules located on the Windward / leeward facades, respectively, and gradually decreasing values in modules located on the Web sides . | Figure 3: Effect of Lateral Loading. | 3. 3  Ã‚  EFFECT OF SHEAR LOADING The global shear VW causes a horizontal force in the apex joint of the diagrid modules, Vw,mod, which intensity depends on the position of the module with respect to the direction of wind load, i. e. the shear force VW is mainly absorbed by the modules located on the web facades, i. e. parallel to the load direction  . | Figure 4: Effect of Shear Loading| 3. 4  Ã‚  EFFECT OF NON-APEX LOADINGFor deriving internal forces in the diagrid elements, it has been implicitly assumed that the external load is transferred to the diagrid module only at the apex node of the module itself. However, since the triangle module usua lly expands over a certain number of stories, transfer of loads to the module occurs at every floor level, thus also concentrated loads along the diagonal length are present ; as a consequence, bending moment and shear force are expected due to this load condition. However the introduction of a horizontal member at each floor girder to diagonal intersection allows for the absorption of the force component orthogonal to the diagonal direction, thus preserving the prevailing axial force condition. | Figure  5: Effect of non-apex loading. | 3.    EFFECT OF HORIZONTAL AND VERTICAL CURVATURE UNDER VERTICAL LOADING   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚   The above simplified analysis of the diagrid module has been carried out implicitly assuming that the plane of the triangular module coincides with the vertical plane; however, recent Applications often concern buildings characterized by curvilinear, non prismatic forms, which require the study of the diagrid curvature effect on the internal force distribution. In particular, by considering that the single module may be inclined of an angle  Ã‚  with respect to the vertical direction, the effect of   Ã‚  both gravity loads and overturning moment gives rise to an additional horizontal force, in the direction Orthogonal to the module plane.Therefore the chords of the diagrid modules, continuously connected Each other along the building perimeter at the diagonal intersections, also act as hopping elements or Ring beams, for absorbing these horizontal forces. | Figure  6: Effect o f vertical and horizontal curvature. | 3. 6  Ã‚  EFFECT OF HORIZONTAL CURVATURE UNDER HORIZONTAL LOADING When the building has a nonrectangular, rounded plans, similar effects due to this horizontal curvature develop under the action of Lateral shear, and the ring beams also collect these outward forces arising in the horizontal plane. | Figure  7: Effect of horizontal curvature. | 4. 1  Ã‚  Ã‚  Ã‚  MATERIALS   USED FOR DIAGRIDDS: Material selection for a Diagrid construction is based on the following factors . They are: a)  Ã‚  Ã‚  Unit weight of the material. b)  Ã‚  Ã‚  Availability of the material. )  Ã‚  Ã‚  Lead Time. d)  Ã‚  Ã‚  Erection Time. e)  Ã‚  Ã‚  Flexibility. f)  Ã‚  Durability. g)  Ã‚  Ã‚  Labor cost. h)  Ã‚  Fire resistance. The basic materials used in Diagrid construction are Steel, Concrete and Wood. The relative merits and demerits of using them are discussed below. I. STEEL : Steel is by far the most popular material for Diagrid construc tions. The typical steel sections used are Wide flanges, Rectangular HSS and Round HSS. ?  Steel Wide Flanges: Advantages-  The weight and Size of wide flanges are optimized to resist the high bending loads many of the members experience. Thus use of wide flanges results in reduced structure weight and flexibility of size.The sections can be prefabricated in multi-panel sections, allowing quick erection by crane, reducing labor costs in the field. Disadvantages-  Pre-fabrication of the Diagrid sections takes a longer lead time. ?  Rectangular and Round HSS: Advantages- As with wide flanges, HSS sections can be prefabricated in multi-panel sections, allowing quick erection time, also reducing labor costs in the field. Disadvantages- Use of HSS sections will need a change in floor layouts as the beams will need to frame into the node points. This reduces the floor flexibility and efficiency. II. CONCRETE: Concrete is another widespread material for Diagrid constructions.It is used both in Precast and Cast-in-situ forms. ?  Precast concrete: Advantages-The flexibility of precast sections allows them to fit to the complex building geometries. Concrete also offers extreme safety against structural fire damage. Disadvantages-  The use of Concrete increases the dead load on the foundations, deflections of long spans, etc. Creep in concrete is also an issue. ?  Cast-in-situ Concrete: Under an Efficient material management system, cast-in-situ concrete is the best material in terms of material cost. Lead time is virtually nothing as cast-in-situ is available on demand. III. TIMBER: Timber is the least popular material for Diagrid constructions.Advantages- Multi-panel sections can reduce erection time and labor cost. Disadvantages  Ã¢â‚¬â€œ Timber cost, both for material and connection, are much higher than the traditional structural materials of steel and concrete. Owing to its lesser material strength, the member sizes would be very large and hence is not preferred for major construction works. Durability and weathering of timber are other major issues. 4. 2  DIAGRID NODE DESIGN | Figure 8: Load path at Node| The diagrid segments are planned to minimize onsite butt welding and the welding locations illustrated in Figure 9. The load path can be divided into two main scenarios, vertical load and horizontal shear their combination), as shown in Figure 8.The vertical load will be transferred in the form of an axial load from the diagrid members above the node to the gusset plate and stiffeners, then to the diagrid members below the nodes as shown. The horizontal shear will be in the form of axial loads in the diagrid members above the node with one in compression and one in tension to the gusset plate and stiffeners. The force will then be transferred as shear force in the gusset plate and then to the other pair of tensile and compressive forces on the diagrid members below the node. From this load path, the shear force at the loca tion of bolt connections is high under lateral loads. Because this may create weak points at the node particularly during earthquakes, the strength of the bolts should be designed carefully. | Figure  9: Node Design Plan| 4.   Ã‚  Ã‚  NODE CONSTRUCTION FOR DIAGRID STRUCTURES Constructability is a serious issue in diagrid structures because the joints of diagrid structures are  more complicated and tend to be more expensive than those of conventional orthogonal structures. In order to reduce jobsite work, prefabrication of nodal elements is essential. Due to the triangular configuration of the diagrid structural system, rigid connections are not necessary at the nodes, and pin connections using bolts can be made more conveniently at the jobsite. If considerately designed using appropriate prefabrication strategy, constructability will not be such a limiting factor of the diagrid structures.Prefabrication of diagrid nodes for conventional rectangular shape buildings can be done relatively easily and economically because many nodes of the same configuration are required in this case. The Hearst Headquarters in New York is the typical case. | Figure  10: Node detail for the Hearst Tower  | The prefabricated nodes are connected to the large built-up diagonal members by bolts at the jobsite. As building form becomes more irregular, generating appropriate construction modules is critical for better constructability. Though it is possible to produce any complex shape construction module using today’s CAD/CAM technology, it is not the most economical solution. Extracting regularity from an irregular building form, and then adjusting the building form following the extracted regularity could be one approach.Another approach could be to make the construction modules relatively regular and design universal connections so that they can accommodate any irregularity. | Figure  11: A Diagrid node after fabrication| 4. 4ERECTION OF DIAGRID NODES During const ruction, the stability in the in-plane direction can be provided by the modules themselves and in the out-of-plane direction can be provided by the tie beams at the node. The temporary restraint to the diagrid and the construction may be minimized. The various steps in the Diagrid erection process include : ? In-place steel shop welding ?  Ã‚  Lifting up piece by piece. ?  Ã‚  Trial shop assembly of parts with high strength bolts. ?  Ã‚  Ã‚  In-place welding. ?  Ã‚  Ã‚  High strength bolts assembly. ?  Ã‚  Ã‚  Setting up perimeter girders |Figure  12:  Construction Plan of Diagrid  | | Figure  13: Diagrid Erection Process| CHAPTER-5 CASE STUDIES 5. 1  Ã‚  SWISS RE BUILDING | Figure  14: Swiss Re Building, London| 30 St. Mary Axe – also known as the Swiss Re Building – in London, is the first modern application and the most representative example of diagrid structure. Designed by Sir Norman Foster, with 40 stories   and an inter-story height of 4 . 15 m, the tower is 180 meters tall. The building is circular in plan with diameter changing along elevation, equal to 56 m at its widest point, at the 20 story, reducing to 49 m at ground level, and to 30 m at the 38 level, where a steel and glass dome tops off the building.The diagrid structure is generated by a pattern of intersecting diagonals which follow the helical path of the so called light wells, created for enforcing natural light and air circulation. It is formed by a series of steel triangles, two-story high and 9 m wide, with an intermediate tie connecting the two diagonals, which gives to the module the aspect of a â€Å"A-shape frame†. The diagonals are CHS members, with cross section between 508 x 40 mm at the lowest floors and 273 x 12. 5 mm at the top, while the chord members have RHS, 250 x 300 mm with wall thickness of 25mm. The circular central core, which has constant diameter along elevation, does not contribute to the lateral resistance and rigidity, being a simple frame structure. 5. 2  HEARST  TOWERThe Hearst Tower in New York was designed by Sir Norman Foster; the building, 46 stories and 183 meters tall, has a prismatic form and a rectangular floor plan, 48 x 37m and is built on an existent 6 storey building. The diagrid structure, creating the characteristic â€Å"diamond effect† in the facade, rises from 12 composite columns, which reach the tenth floor starting from the ground level. The diagrid module is 12. 25 m wide and 16. 54 m high, and covers four stories. The diagonal cross section are I shape, with maximum size W14x370 at the base of the diagrid (tenth level),   while the megacolumns between the tenth and the ground level are concrete filled box section 1100 x 1100 x 10m. | Figure  15: The Hearst Tower, New York. | 5. 3  GUANGZHOU WEST TOWERThe Guangzhou West Tower, designed by Wilkinson Eyre architects, London with 103 stories and a height of 440m, is the tallest building in China and one of the tallest in the world. The building has a curvilinear shape along elevation and the floor plate is an equilateral triangle with round-corners, with side 65 m at the base, increasing to a maximum value of   65 m at approximately 1/3 of the way up the building, at which point the side begins to reduce, up to 43. 5 m at the top. It has a composite structure, made by a central concrete core and perimeter diagrid structure, with the diagrid module expanding on six stories, 12. 4 m wide and 24. 8 m high. The diagonals are steel tubular members filled by concrete (CFST), with size ranging between 1080 x 55 mm at the first floor and 700 x 20mm at the top.The concrete core has a triangle shape with chamfered corners and fully participates to the lateral resistance up to the seventh floor, where it is eliminated, leaving place to a central giant atrium for the hotel which occupies the upper floors. | Figure  16:   Guangzhou West Tower, China| CHAPTER-6 MERITS AND DEMERITS OF DIAGRIDS 6. 1  Ã‚  Ã‚  Ã‚  Ã‚  MERITS OF DIAGRIDS: Some major benefits of using Diagrids in structures are discussed below. 1)  Ã‚  Ã‚  The Diagrid structures besides the service core have mostly column free exterior and interior, hence  Ã‚   free and clear, unique floor plans are Possible. 2)  Ã‚  The Glass facades and dearth of interior columns allow generous amounts of day lighting into the structure. 3)  Ã‚  Ã‚  The use of Diagrids results in roughly 1/5th(20%) reduction in steel as compared to Braced frame structures. )  Ã‚  Ã‚  The construction techniques involved are simple, yet they need to be perfect. 5)  Ã‚  Ã‚  The Diagrids makes maximum exploitation of the structural Material. 6)  Ã‚  The diagrid Structures are aesthetically dominant and expressive. 7)  Ã‚  Redundancy in the DiaGrid design is obvious. It is this redundancy then that can transfer load from a failed portion of the structure to another. Skyscraper structural failure, as it is such an important/ promi nent topic, can be minimized in a DiaGrid design A DiaGrid has better ability to redistribute load than a Moment Frame skyscraper. Thus creating a deserved appeal for the DiaGrid in today’s landscape of building. 6.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  DEMERITS OF DIAGRIDS: Some demerits of using Diagrids are mentioned below: 1)  Ã‚  As of yet, the Diagrid Construction techniques are not   thoroughly explored. 2)  Ã‚  Lack of availability of skilled workers . Construction crews   have little or no experience    creating a DiaGrid skyscraper. 3)  Ã‚  Ã‚  The DiaGrid can dominate aesthetically, which can be an issue depending upon design intent. 4)  Ã‚  It is hard to design windows that create a regular language from floor to floor. 5)  Ã‚  The DiaGrid is heavy-handed ( can be clumsy or unstable) if not executed properly. CHAPTER -7 CONCLUSION We are at a time when the global population is inching the 7 billion mark.Around the globe we witness frequent recurrence of natural calamities, depletion and degradation of vital life supporting systems, all presumed to be the impacts of Global warming, making life miserable on earth. It is high time for humanity to switch to sustainable and eco-friendly lines of infrastructure development. The construction industry, the greatest contributor to green house emissions, has the moral obligation to play the lead. The most stable and sustainable of ecosystems is the natural ecosystems. Attainment of sustainability goals would require sound knowledge and understanding of nature’s mechanisms and modeling of all artificial infrastructure in close resemblance to it.Owing to the complexity due to size and geometry of the natural systems, development of artificial infrastructure on the lines of biomimicking principles, is in fact the greatest challenge the modern day builder would have to confront with. Thus a modern day structural system should have extreme efficiency in terms of strength, expression, and geometric versatility. Most of the present structural systems are highly advanced in terms of structural efficiency and aesthetic quality, but lacks the much needed geometric versatility. As we have seen, the diagrids, the latest mutation of tubular structures, has in addition to strength and aesthetics, that extra quality of geometric versatility, making it the most suited structural system to this respect.Thus the diagrid, with an optimal combination of qualities of aesthetic expression, structural efficiency and geometric versatility is indeed the language of the modern day builder.

Diagonalized applications of structural steel members for providing efficient solutions both in terms of strength and stiffness are not   new ,however nowadays a renewed interest in and a widespread application of diagrid is registered with reference to large span and high rise buildings, particularly when they are characterized by complex geometries and curved shapes, sometimes by completely free forms.Compared to conventional orthogonal structures for tall buildings such as framed tubes, diagrid structures carry lateral wind loads much more efficiently by their diagonal members’ axial action. ;   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Among the large-span buildings some examples are represented by the Seatlle Library, the London City Hall, the One Shelley Street in Sydney, and more recently by several outstanding Pavilions realized at the Shanghai 2010 Expo, (e. g. France, UAE) as well as by some dazzling projects like the Astana National library.Among tall buildings, noteworthy examples are the Swiss Re building in London, the Hearst tower in New York, the CCTV headquarters building in Beijing, the Mode Gakuen Spiral Tower in Aichi, the Cyclone Tower in Asan, the West tower in Guangzhou, the Lotte super tower in Seoul, the Capital Gate in Abu Dhabi, the Bow project in Calgary, the Building of Qatar Ministry of Foreign Affairs in Doha. .  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     The diagrid systems are the evolution of braced tube structures, since the erimeter configuration sti ll holds for preserving the maximum bending resistance and rigidity, while, with respect to the braced tube, the mega-diagonal members are diffusely spread over the facade, giving rise to closely spaced diagonal elements and allowing for the complete elimination of the conventional vertical columns. Therefore the diagonal members in diagrid structures act both as inclined columns and as bracing elements, and carry gravity loads as well as lateral forces due to their triangulated configuration, mainly internal axial forces arise in the members, thus minimizing shear racking effects.To begin with the behavior of basic Diagrid   Ã‚  module is   Ã‚  discussed, followed by construction process. Then the merits and demerits of   Diagrids are listed. CHAPTER-2 THE TRIANGULAR DIAGRID MODULE 2. 1  Ã‚  Ã‚  INTRODUCTION Diagrid structure is modeled as a beam, and subdivided longitudinally into modules according to this repetitive diagonal pattern. Each Diagrid module is defined by a si ngle level of diagonals that extend over ‘n’ stories. | Figure 1: 8 storey Diagrid with 60 degree diagonal angle| 2. 2 MODULE GEOMETRYDiagrid structures, like all the tubular configurations, utilize the overall building plan dimension for counteracting overturning moment and providing flexural rigidity through axial action in the diagonals, which acts as inclined columns; however, this potential bending efficiency of tubular configuration is never fully achievable, due to shear deformations that arise in the building â€Å"webs†; with this regard, diagrid systems, which provide shear resistance and rigidity by means of axial action in the diagonal members, rather than bending moment in beams and columns, allows for a nearly full exploitation of the theoretical bending resistance. Being the diagrid a triangulated configuration of structural members, the geometry of the single module plays a major role in the internal axial force distribution, as well as in conferr ing global shear and bending rigidity to the building structure. While a module angle equal to 35 ° ensures the maximum shear rigidity to the diagrid system, the maximum engagement of diagonal members for bending stiffness corresponds to an angle value of 90 °, i. e. vertical columns.Thus in diagrid systems, where vertical columns are completely eliminated and both shear and bending stiffness must be provided by diagonals, a balance between this two conflicting requirements should be searched for defining the optimal angle of the diagrid module. Usually Isosceles triangular geometry is used. i. OPTIMAL ANGLE: As in the diagrids, diagonals carry both  shear and moment. Thus, the optimal angle of diagonals  is highly dependent upon the building height. Since the  optimal angle of the columns for maximum bending  rigidity is 90 degrees and that of the diagonals for  maximum shear rigidity is about 35 degrees, it is  expected that the optimal angle of diagonal members fo rdiagrid structures will fall between these angles and as  the building height increases, the optimal angle also  increases. Usually adopted range is 60 -70 degree. i. MODULE DIMENSIONS: ?  Ã‚  Ã‚  Height of the module:  Ã‚  It depends on the number of stories stacked per module. Usually 2 – 6 stories are stacked per diagrid with average floor height varying from 3. 5 -4. 15 m on an average. ?  Ã‚  Ã‚  Base of the module:  Ã‚  It depends on the height and optimal angle (apex angle) of the diagrid. CHAPTER-3 STRUCTURAL  Ã‚   ACTION OF A DIAGRID MODULE 3. 1  Ã‚  EFFECT OF GRAVITY LOADING The diagrid module under gravity loads G is subjected to a downward vertical force, NG,mod, causes the two diagonals being both in compression and the horizontal chord in tension. | Figure 2: Effect of Gravity Loading. | 3. 2  Ã‚  Ã‚  Ã‚  EFFECT OF LATERAL LOADINGUnder horizontal load W, the overturning moment MW causes vertical forces in the apex joint of The diagrid modules, NW,mod, with direction and intensity of this force depending on the position of the Diagrid module, with upward / downward direction and maximum intensity in modules located on the Windward / leeward facades, respectively, and gradually decreasing values in modules located on the Web sides . | Figure 3: Effect of Lateral Loading. | 3. 3  Ã‚  EFFECT OF SHEAR LOADING The global shear VW causes a horizontal force in the apex joint of the diagrid modules, Vw,mod, which intensity depends on the position of the module with respect to the direction of wind load, i. e. the shear force VW is mainly absorbed by the modules located on the web facades, i. e. parallel to the load direction  . | Figure 4: Effect of Shear Loading| 3. 4  Ã‚  EFFECT OF NON-APEX LOADINGFor deriving internal forces in the diagrid elements, it has been implicitly assumed that the external load is transferred to the diagrid module only at the apex node of the module itself. However, since the triangle module usua lly expands over a certain number of stories, transfer of loads to the module occurs at every floor level, thus also concentrated loads along the diagonal length are present ; as a consequence, bending moment and shear force are expected due to this load condition. However the introduction of a horizontal member at each floor girder to diagonal intersection allows for the absorption of the force component orthogonal to the diagonal direction, thus preserving the prevailing axial force condition. | Figure  5: Effect of non-apex loading. | 3.    EFFECT OF HORIZONTAL AND VERTICAL CURVATURE UNDER VERTICAL LOADING   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚   The above simplified analysis of the diagrid module has been carried out implicitly assuming that the plane of the triangular module coincides with the vertical plane; however, recent Applications often concern buildings characterized by curvilinear, non prismatic forms, which require the study of the diagrid curvature effect on the internal force distribution. In particular, by considering that the single module may be inclined of an angle  Ã‚  with respect to the vertical direction, the effect of   Ã‚  both gravity loads and overturning moment gives rise to an additional horizontal force, in the direction Orthogonal to the module plane.Therefore the chords of the diagrid modules, continuously connected Each other along the building perimeter at the diagonal intersections, also act as hopping elements or Ring beams, for absorbing these horizontal forces. | Figure  6: Effect o f vertical and horizontal curvature. | 3. 6  Ã‚  EFFECT OF HORIZONTAL CURVATURE UNDER HORIZONTAL LOADING When the building has a nonrectangular, rounded plans, similar effects due to this horizontal curvature develop under the action of Lateral shear, and the ring beams also collect these outward forces arising in the horizontal plane. | Figure  7: Effect of horizontal curvature. | 4. 1  Ã‚  Ã‚  Ã‚  MATERIALS   USED FOR DIAGRIDDS: Material selection for a Diagrid construction is based on the following factors . They are: a)  Ã‚  Ã‚  Unit weight of the material. b)  Ã‚  Ã‚  Availability of the material. )  Ã‚  Ã‚  Lead Time. d)  Ã‚  Ã‚  Erection Time. e)  Ã‚  Ã‚  Flexibility. f)  Ã‚  Durability. g)  Ã‚  Ã‚  Labor cost. h)  Ã‚  Fire resistance. The basic materials used in Diagrid construction are Steel, Concrete and Wood. The relative merits and demerits of using them are discussed below. I. STEEL : Steel is by far the most popular material for Diagrid construc tions. The typical steel sections used are Wide flanges, Rectangular HSS and Round HSS. ?  Steel Wide Flanges: Advantages-  The weight and Size of wide flanges are optimized to resist the high bending loads many of the members experience. Thus use of wide flanges results in reduced structure weight and flexibility of size.The sections can be prefabricated in multi-panel sections, allowing quick erection by crane, reducing labor costs in the field. Disadvantages-  Pre-fabrication of the Diagrid sections takes a longer lead time. ?  Rectangular and Round HSS: Advantages- As with wide flanges, HSS sections can be prefabricated in multi-panel sections, allowing quick erection time, also reducing labor costs in the field. Disadvantages- Use of HSS sections will need a change in floor layouts as the beams will need to frame into the node points. This reduces the floor flexibility and efficiency. II. CONCRETE: Concrete is another widespread material for Diagrid constructions.It is used both in Precast and Cast-in-situ forms. ?  Precast concrete: Advantages-The flexibility of precast sections allows them to fit to the complex building geometries. Concrete also offers extreme safety against structural fire damage. Disadvantages-  The use of Concrete increases the dead load on the foundations, deflections of long spans, etc. Creep in concrete is also an issue. ?  Cast-in-situ Concrete: Under an Efficient material management system, cast-in-situ concrete is the best material in terms of material cost. Lead time is virtually nothing as cast-in-situ is available on demand. III. TIMBER: Timber is the least popular material for Diagrid constructions.Advantages- Multi-panel sections can reduce erection time and labor cost. Disadvantages  Ã¢â‚¬â€œ Timber cost, both for material and connection, are much higher than the traditional structural materials of steel and concrete. Owing to its lesser material strength, the member sizes would be very large and hence is not preferred for major construction works. Durability and weathering of timber are other major issues. 4. 2  DIAGRID NODE DESIGN | Figure 8: Load path at Node| The diagrid segments are planned to minimize onsite butt welding and the welding locations illustrated in Figure 9. The load path can be divided into two main scenarios, vertical load and horizontal shear their combination), as shown in Figure 8.The vertical load will be transferred in the form of an axial load from the diagrid members above the node to the gusset plate and stiffeners, then to the diagrid members below the nodes as shown. The horizontal shear will be in the form of axial loads in the diagrid members above the node with one in compression and one in tension to the gusset plate and stiffeners. The force will then be transferred as shear force in the gusset plate and then to the other pair of tensile and compressive forces on the diagrid members below the node. From this load path, the shear force at the loca tion of bolt connections is high under lateral loads. Because this may create weak points at the node particularly during earthquakes, the strength of the bolts should be designed carefully. | Figure  9: Node Design Plan| 4.   Ã‚  Ã‚  NODE CONSTRUCTION FOR DIAGRID STRUCTURES Constructability is a serious issue in diagrid structures because the joints of diagrid structures are  more complicated and tend to be more expensive than those of conventional orthogonal structures. In order to reduce jobsite work, prefabrication of nodal elements is essential. Due to the triangular configuration of the diagrid structural system, rigid connections are not necessary at the nodes, and pin connections using bolts can be made more conveniently at the jobsite. If considerately designed using appropriate prefabrication strategy, constructability will not be such a limiting factor of the diagrid structures.Prefabrication of diagrid nodes for conventional rectangular shape buildings can be done relatively easily and economically because many nodes of the same configuration are required in this case. The Hearst Headquarters in New York is the typical case. | Figure  10: Node detail for the Hearst Tower  | The prefabricated nodes are connected to the large built-up diagonal members by bolts at the jobsite. As building form becomes more irregular, generating appropriate construction modules is critical for better constructability. Though it is possible to produce any complex shape construction module using today’s CAD/CAM technology, it is not the most economical solution. Extracting regularity from an irregular building form, and then adjusting the building form following the extracted regularity could be one approach.Another approach could be to make the construction modules relatively regular and design universal connections so that they can accommodate any irregularity. | Figure  11: A Diagrid node after fabrication| 4. 4ERECTION OF DIAGRID NODES During const ruction, the stability in the in-plane direction can be provided by the modules themselves and in the out-of-plane direction can be provided by the tie beams at the node. The temporary restraint to the diagrid and the construction may be minimized. The various steps in the Diagrid erection process include : ? In-place steel shop welding ?  Ã‚  Lifting up piece by piece. ?  Ã‚  Trial shop assembly of parts with high strength bolts. ?  Ã‚  Ã‚  In-place welding. ?  Ã‚  Ã‚  High strength bolts assembly. ?  Ã‚  Ã‚  Setting up perimeter girders |Figure  12:  Construction Plan of Diagrid  | | Figure  13: Diagrid Erection Process| CHAPTER-5 CASE STUDIES 5. 1  Ã‚  SWISS RE BUILDING | Figure  14: Swiss Re Building, London| 30 St. Mary Axe – also known as the Swiss Re Building – in London, is the first modern application and the most representative example of diagrid structure. Designed by Sir Norman Foster, with 40 stories   and an inter-story height of 4 . 15 m, the tower is 180 meters tall. The building is circular in plan with diameter changing along elevation, equal to 56 m at its widest point, at the 20 story, reducing to 49 m at ground level, and to 30 m at the 38 level, where a steel and glass dome tops off the building.The diagrid structure is generated by a pattern of intersecting diagonals which follow the helical path of the so called light wells, created for enforcing natural light and air circulation. It is formed by a series of steel triangles, two-story high and 9 m wide, with an intermediate tie connecting the two diagonals, which gives to the module the aspect of a â€Å"A-shape frame†. The diagonals are CHS members, with cross section between 508 x 40 mm at the lowest floors and 273 x 12. 5 mm at the top, while the chord members have RHS, 250 x 300 mm with wall thickness of 25mm. The circular central core, which has constant diameter along elevation, does not contribute to the lateral resistance and rigidity, being a simple frame structure. 5. 2  HEARST  TOWERThe Hearst Tower in New York was designed by Sir Norman Foster; the building, 46 stories and 183 meters tall, has a prismatic form and a rectangular floor plan, 48 x 37m and is built on an existent 6 storey building. The diagrid structure, creating the characteristic â€Å"diamond effect† in the facade, rises from 12 composite columns, which reach the tenth floor starting from the ground level. The diagrid module is 12. 25 m wide and 16. 54 m high, and covers four stories. The diagonal cross section are I shape, with maximum size W14x370 at the base of the diagrid (tenth level),   while the megacolumns between the tenth and the ground level are concrete filled box section 1100 x 1100 x 10m. | Figure  15: The Hearst Tower, New York. | 5. 3  GUANGZHOU WEST TOWERThe Guangzhou West Tower, designed by Wilkinson Eyre architects, London with 103 stories and a height of 440m, is the tallest building in China and one of the tallest in the world. The building has a curvilinear shape along elevation and the floor plate is an equilateral triangle with round-corners, with side 65 m at the base, increasing to a maximum value of   65 m at approximately 1/3 of the way up the building, at which point the side begins to reduce, up to 43. 5 m at the top. It has a composite structure, made by a central concrete core and perimeter diagrid structure, with the diagrid module expanding on six stories, 12. 4 m wide and 24. 8 m high. The diagonals are steel tubular members filled by concrete (CFST), with size ranging between 1080 x 55 mm at the first floor and 700 x 20mm at the top.The concrete core has a triangle shape with chamfered corners and fully participates to the lateral resistance up to the seventh floor, where it is eliminated, leaving place to a central giant atrium for the hotel which occupies the upper floors. | Figure  16:   Guangzhou West Tower, China| CHAPTER-6 MERITS AND DEMERITS OF DIAGRIDS 6. 1  Ã‚  Ã‚  Ã‚  Ã‚  MERITS OF DIAGRIDS: Some major benefits of using Diagrids in structures are discussed below. 1)  Ã‚  Ã‚  The Diagrid structures besides the service core have mostly column free exterior and interior, hence  Ã‚   free and clear, unique floor plans are Possible. 2)  Ã‚  The Glass facades and dearth of interior columns allow generous amounts of day lighting into the structure. 3)  Ã‚  Ã‚  The use of Diagrids results in roughly 1/5th(20%) reduction in steel as compared to Braced frame structures. )  Ã‚  Ã‚  The construction techniques involved are simple, yet they need to be perfect. 5)  Ã‚  Ã‚  The Diagrids makes maximum exploitation of the structural Material. 6)  Ã‚  The diagrid Structures are aesthetically dominant and expressive. 7)  Ã‚  Redundancy in the DiaGrid design is obvious. It is this redundancy then that can transfer load from a failed portion of the structure to another. Skyscraper structural failure, as it is such an important/ promi nent topic, can be minimized in a DiaGrid design A DiaGrid has better ability to redistribute load than a Moment Frame skyscraper. Thus creating a deserved appeal for the DiaGrid in today’s landscape of building. 6.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  DEMERITS OF DIAGRIDS: Some demerits of using Diagrids are mentioned below: 1)  Ã‚  As of yet, the Diagrid Construction techniques are not   thoroughly explored. 2)  Ã‚  Lack of availability of skilled workers . Construction crews   have little or no experience    creating a DiaGrid skyscraper. 3)  Ã‚  Ã‚  The DiaGrid can dominate aesthetically, which can be an issue depending upon design intent. 4)  Ã‚  It is hard to design windows that create a regular language from floor to floor. 5)  Ã‚  The DiaGrid is heavy-handed ( can be clumsy or unstable) if not executed properly. CHAPTER -7 CONCLUSION We are at a time when the global population is inching the 7 billion mark.Around the globe we witness frequent recurrence of natural calamities, depletion and degradation of vital life supporting systems, all presumed to be the impacts of Global warming, making life miserable on earth. It is high time for humanity to switch to sustainable and eco-friendly lines of infrastructure development. The construction industry, the greatest contributor to green house emissions, has the moral obligation to play the lead. The most stable and sustainable of ecosystems is the natural ecosystems. Attainment of sustainability goals would require sound knowledge and understanding of nature’s mechanisms and modeling of all artificial infrastructure in close resemblance to it.Owing to the complexity due to size and geometry of the natural systems, development of artificial infrastructure on the lines of biomimicking principles, is in fact the greatest challenge the modern day builder would have to confront with. Thus a modern day structural system should have extreme efficiency in terms of strength, expression, and geometric versatility. Most of the present structural systems are highly advanced in terms of structural efficiency and aesthetic quality, but lacks the much needed geometric versatility. As we have seen, the diagrids, the latest mutation of tubular structures, has in addition to strength and aesthetics, that extra quality of geometric versatility, making it the most suited structural system to this respect.Thus the diagrid, with an optimal combination of qualities of aesthetic expression, structural efficiency and geometric versatility is indeed the language of the modern day builder.

Is college worth the cost(investment) to attend Essay

Is college worth the cost(investment) to attend - Essay Example People believe that their investments would be returned to them in spite of high price for education. People dream about numerous chances and opportunities of having higher returns after their investments into education. At the same time, there are different political parties, which, on the one hand, promote their social shifts through educational institutions, but, on the other hand, do not want to make reliable investments in education. Argument 1 Different prospects of higher returns are often misunderstood by people and they are often concerned about financial side of education and its high financial returns. Quality of education and personal striving in this process is often omitted. Education requires a high emotional and mind contribution. Different studies of the past years summarize the following assumptions about education: â€Å"the idea that college is an excellent investment paying a high return in terms of lifetime income has been buttressed by numerous studies over the years purporting to show that college graduates earn a large premium over a lifetime in comparison to individuals who earn only a high school diploma or who attend some college without completing a four-year degree† (Wood 210). Again the matter is about financial and material side of the education. There is no word about qualitative and emotional load of education. A high intellectual attainment is very much required from the stud ents in the process of education. Educational institutions are on the way of improvement of their potential goals. A marketplace credential and a diploma of higher education are two different things. There is no way to compare them. A student’s wholeness and intellectual attainment are proved by the diploma. Intellectual maturity and mind’s ability to produce emotional and creative power should be the main points for confirmation in the process of higher education. Argument 2 The University has often been

Management - Service Package Essay Example | Topics and Well Written Essays - 1250 words

Management - Service Package - Essay Example An elderly care center is a specialized place designed to take care of elderly people in the society. Therefore, a number of supporting facilities must be taken care of before elderly people are admitted into the elderly care center. In some states, it is a requirement that all elderly care centers comply with state regulations concerning the nursing home reform act. Supporting facilities Supporting facilities refer to physical resources that must be in place before a service can be given out. A key component of facilitating goods encompasses architectural appropriateness, which means that the structures should be tailored according to the needs of the elderly people. In terms of architecture, the houses should be constructed in line with the prevailing climatic conditions of the place where the elderly care centre will be located (White & Duncan 263). The houses should encompass various rooms with washrooms, which are well maintained to cater for the needs of the elderly. The archit ectural design should provide for facilities such as places where the elderly can rest whenever they want to relax. The interior decor should consist of quality furniture and the house should be well decorated. The tables, sofas, and other furniture should be made with appropriate designs and from quality timber. The layout of the facility should be placed in a location with a good flow of traffic to avoid any unnecessary disturbance to the elderly. Other essential supporting facilities include facilities to ensure safety against fire, grab bars in bathrooms and toilets, private toilets and bathrooms, safes, and locked drawers. The houses should also be equipped with supporting facilities such as temperature controls and heating facilities. Other supporting facilities include fitness rooms, libraries, activity rooms, theatres, open grounds for exercises, and walking facilities for persons with walking problems (White & Duncan 268). To improve on security within the housing facility, wander alert systems, alarmed exits, automated fire sprinkler systems, and enclosed yards should be considered. Facilitating goods Facilitating goods refer to goods consumed by buyer or goods as well as materials purchased and consumed by the providers of services. The facilitating goods necessary in an elderly care centre include quality mattresses and warm blankets. Quality will ensure that the elderly feel comfortable when they sleep while the warm blankets will significantly reduce the chances of them to feel cold. Sleeping in a comfortable place can reduce the chances of conditions such as backaches and flu. The caregivers should also be provided with mattresses of high quality as well as warm blankets. This will ensure that they do not have any hindrance while providing services to the elderly (Johnston & Clark 32). Other essential facilitating goods, which should be made available in the elderly care centre, include toothpaste, shampoo, as well as uniforms for the elders and caregivers. Toothpaste and shampoo are essential goods, which ensure the general well being and hygiene in the elderly care centre. Uniforms should be provided as they play an essential role in identifying both the caregivers and the elders. This helps in differentiating between the elderly and caregivers. Service explicit The explicit services refer to benefits, which can be observed and felt with the use of the senses. The achievement of explicit services calls for the employment of qualified caregivers who can treat

Health and Safety at work course work Coursework

Health and Safety at work course work - Coursework Example Thus Planning-I consists of five separate entities that are deeply interlinked. VISION OF PLANNING 1:- Keeping house in efficient and productive order, set timelines for every project, pursue relentlessly, while onus of every project is with a specific person. To be a success story, Planning – I Wing will work on the motto of ‘Reach out to all, net and tune well domestically within ERRA and beyond in the sister Organizations, Institutions and Ministries for the collective well being of the Earthquake (EQ) affected people and good reputation of ERRA’. Achievements have no limits, efforts have no bounds. Field is vast open. Let everyone see and judge, who runs the fastest and for how long. CHANNELS FOR COMMUNICATION: - The channels that are used in the wing are mainly the documentation accompanied by the verbal communication. The following are the modes of communications. 1) DOCUMENTATION AND APPROVALS: - Any new project to be implemented or any alteration or advanc ements in the projects conducted by the ERRA are documented properly. And the approvals for all the activities are approved by bottom approach. 2) STAFF AND EMPLOYEE MEETINGS: - All the staff meetings and employee meetings are being conducted in a regular manner depending upon the sensitivity of the projects. These meetings are conducted in the same departments or rather with collaborative department of choice as per the requirements. 3) INTERNET AND EMAIL NOTIFICATION:- Most of the notifications are given to the department via email notifications and phone calls directly. So there is a strictness to check the emails notifications daily so that every person must be updated with the current situation regularly. 4) FAX: - If there is a meeting or any negotiations or problems that need the communication with other department, then there is a three way communication procedure that includes fax along with telephone and email notification. 5) VERBAL: - Also there is a way communication by the direct boss to the employee verbally if he or she has to notify something or there is any important issue that needs discussion. HASAWA IMPLEMENTATION:- Health and Safety at Work etc. Act 1974 promotes the safety and health at workplace and it is very effective in promoting the good health. It involves the duties imposed on employers, employees, contractors, suppliers of goods and substances for use at work, persons that are in control of work premises, and those who has a charge to manage and maintain them, and persons in general. So the duties of the HASAWA are applied on all of the employees and all other important persons that can contribute even a pinch towards promoting good health or violating health regulations. BEST CHANNEL TO PROMOTE HASAWA IN THE DEPARTMENT:- The best way to aware people and to implement HASAWA is through telecommunication and workshops. The reason for this channel is due to the reason that in Pakistan, there is shortage of electricity and there is m uch obvious that the electricity is not a reliable source for notification for any activity or information. So emails could be unreliable in this case which could be a big problem. And also the telecommunication is not much expensive in Pakistan and here there is lot of networks giving many cost effective packages. As

Introduction to Psychology Essay Example | Topics and Well Written Essays - 2000 words

Introduction to Psychology - Essay Example Having said that one must understand that it is basically not easy to have management between a demanding job and taming children, not to forget the successful completion of household responsibilities as well. When one speaks to his colleagues or neighbors about the same, the result is that nearly everyone is passing through the same phase, it is just a matter of how much pressure and stress a particular individual can take, at a particular moment of time. Stress is indeed a very common problem. Just as all the good things in life, the comfort of modern living cannot be have on the part of the people without paying a cost for it. Among other things that have come hand in hand with the same, it has brought about the phenomenon of stress alongside it nonetheless. This problem seems to emanate all the same from the sort of commercialization that we are witnessing in the present times and not to forget the ruthless market economies and a senseless notion of consumerism attached with this. Especially true is the fact that spending money has become the sole criterion for success and achievement in the modern times. For a number of people, the rat race for acquiring money and material possessions is a symbol of success that they have achieved and it given more importance by the society in which we live in that aims to signify people by the standards as laid down by material possessions and the amount of money that one has. This rat race brin gs with it heaps of stress and tension and anxious living conditions are a manifestation of what can bring a person down every now and then. This kind of intensity was studied by a number of different research studies which stated that stress forms up as the most basic cause of nearly 80 percent of all human illnesses – which accounts for a huge statement if not a huge figure so to speak. One must understand that stress and anxiety are in all essence mental problems and that they develop as the mind chases as

An HIV Symptom Management Intervention for African-American mothers Essay

An HIV Symptom Management Intervention for African-American mothers - Essay Example The main purpose of this study was to "determine the efficacy of an HIV self-care symptom management intervention in reducing emotional distress and improving health among low income African American mothers with HIV." The study was based on the Maternal HIV Self-Care Symptom Management framework. The framework was adapted from the University of California-San Francisco model for symptom management as well as the current literature and studies on African-American women with HIV. As in most studies, a control and an intervention group were formed. In both groups, the HIV infected African-American women reported low income and were mothers of at least one child under the age of 9. 17 grandmothers were also involved in this study, 8 of which were placed in the intervention group. In the intervention group, the implemented procedures regarding the Maternal HIV Self-Care Symptom Management framework were the same for all subjects. The procedures regarding data collection were also the same. Data was collected during 3 data collection points: once during the enrollment of the patients in the clinics, and twice primarily in their homes. Between data collection points, the mothers were telephoned twice, in order to help with retention.

'Stalin blundered into the Cold War.' Discuss Essay

'Stalin blundered into the Cold War.' Discuss - Essay Example Indeed, there are facets of the Cold War debate over which many of the contemporary scholars are in agreement, particularly with reference to Stalin’s paranoid personality. The focus of this study, however, is a matter of contention amongst eminent Cold War historians. Whether Stalin blundered into the Cold War out of a confusion and misjudgment of his adversaries’ intentions that derived from his suspicious personality, or whether the reality of an aggressive US foreign policy nurtured Stalin’s existing paranoia, thus forcing him into an unavoidable conflict will be one of the central themes of discussion. Taking into account and critiquing the work of prominent Cold War historians, this essay will serve to evaluate the origins of the Cold War with particular reference to Stalin. The study aims to demonstrate that Stalin greatly overestimated the US desire for war, and blundered into the Cold War as a result of his paranoia and obsession with personal and domest ic security. Looking at the Cold War through the lens of Gaddis, Matsny, Zubok and Pleshakov, a conclusion can be drawn towards how the Cold War originated from miscalculation and lack of judgment on part of Stalin. John Lewis Gaddis is one of the most influential post revisionist historians of the Cold War. In his book titled We Now Know, he clearly does not see Stalin as blundering into the Cold War. In fact, he is seen as a conscious initiator of the events that led to it, while the US is represented as merely reacting to the threatening desire Stalin held for world domination. Influenced by â€Å"Marxist Internationalism† and â€Å"Czarist Imperialism†1, Stalin had a personality that was conducive to paranoia and insecurity. It is this fusion of ideologies, coupled with an insecure personality that led to the Cold War. Gaddis therefore, sees Stalin’s ideology as a key figure in the Cold War. In its essence, Gaddis sees the Cold War as an ideological war betw een America and the Soviet Union, where American pluralist democracy and capitalism is argued as inherently superior to Soviet communism, and is the cure to the threat of a communist world. American historian Vojtech Matsny offers a distinct insight into the Cold War, and addresses one of the integral issues that Gaddis conveniently overlooks. In The Cold War and Soviet Insecurity, Matsny revolves around the figure and personality of Stalin, and his preoccupation with maintaining his autocratic rule. Stalin’s imperialistic approach towards rule deflects through his paranoia and insecurity that eventually led him into the Cold War. Aware of the lack of popular support his regime had, Stalin intelligently chose to cash in on the 2fundamental Bolshevik belief that â€Å"the outside world remained implacably hostile†. Carefully carving out a sense of â€Å"us† and â€Å"them† through help of the revolutionary communist ideology, Stalin’s prime objectiv e was to preserving his regime and maintaining power within the Soviet Union rather than world domination. As Matsny argues, Stalin did not deliberately wish for a Cold War, but considering his Soviet ideology and insecure imperialism, could not avoid it. For Matsny therefore, â€Å"

Procter and Gamble Company Essay Example for Free

Procter and Gamble Company Essay Background Procter and Gamble was formed by James Gamble William Procter in 1837 by a candle manufacturer Procter and a soap manufacturer Gamble. This consumer product company started with a vision to grow to a $33 billion company and by 1879 it started selling its products directly to the consumers, by 1890 it has gained its legal corporation and ever since it has doubled it sales every ten years. PG growth was driven by innovation not optimization. Radical innovation served as their backbone to success with other factors such as geographic expansion, product line extensions and acquisitions contributing to its growth. Some of its famous and successful acquisitions were, Duncan Hines, Clorox, charmin Paper mills, Folgers Coffee, NorwichEaton, Vicks (NyQuil), Noxell and Max Factor. It also recieves  the credit for developing innovative and advanced technology based products during 1940’s such as Tide, Crest,Pampers, Bounce etc.By the end of 1980’s PG had its operations in 58 countries,its reputation was built with its new product development strategiesÍ ¾ they produced varied range of consumer products such that these products should meet â€Å"basic consumer needs† and create â€Å"superior total value† creating a brand image for the company. As noted in Kevin Kelly’s quote â€Å"Wealth in new regime flows directly from innovation and not optimization†, i.e. wealth is not gained by perfecting the known, but imperfecting the unknown. PG successfully used this strategy to earn its reputation as one of the largest company in Cincinnati in 1895 and in 1995 earned the National Medal of technology, the highest given award in United states. PG was also known for its strong ethics, values and recruiting the best and brightest. RD was a major focus of PG. In 1995 PG spent 1.3billion on RD,and emphasis was laid on combination of multiple RD competencies and there were a lot of cross fertilization of technology. They also had an attractive work culture, employee compensation and had a structure in place which assured employees of growing within the organization with its up through the rank approach which fostered innovation. In the process of growing, PG moved out of their old tradition of new product development and concentrated completely on the global expansion and development of existing products. With structured product  sectors in place, PG had some difficulty fitting some new product idea into any of the available category which led to the rejection on various novel ideas. In 1993, the company started the Strengthening Global Effectiveness (SGE) with the goal of increasing profits through cost reduction which was achieved by reengineering  and reformation of distribution and manufacturing. This led to a successful increase in profits from 10% to 17% in a year. In the same year, CEO John Pepper said that their was an urge for developments of new brands in order to fulfill the companies longtime goals of increasing their sales. Mark Collar, Vice President and General Manager of New Business Development and a part of SGE said that a breakthrough is required to manage and accelerate the company’s innovation process. In addition, the concept of cross fertilization was fading out gradually so their was a requirement of a new innovation team that can incorporate the old traditions followed by the company during the 1960’s. Therefore this lead to the formation of Innovation Leadership Team (ILT) in 1993. The top seven officers of the company were a part of this team: John Pepper(Chairman and CEO)Í ¾ Durk Jager(President and COO)Í ¾ Wolfgang Berndt(Executive VP North America)Í ¾ Gordon Brunner(Senior VP Research and Development)Í ¾ Gary Martin(Senior VP Information Services and Product Supply) and Eric Nelson(Senior VP and CFO)Í ¾ Robert Wehling (Senior VP Advertising and Market Research). The ILT’s responsibility is to investigate the portfolio of the projects under development and projects on shelf, select valuable projects that add value to the firm. Soon Corporate Innovation Fund(CIF) was established for the funding the research on new products developments. The employees can report projects irrespective of their sector and obtain approval at very fast pace on appropriate projects.

What Is Finishing School Marketing Essay

What Is Finishing School Marketing Essay A finishing school is the final polish to your education to make you an all-rounder with a good personality, grooming, excellent personal etiquette and dress sense. A well groomed person with a pleasant personality stands out in a crowd and has a higher chance of ready acceptance in any setting be it the job market, family environment or peer group. Need for a Finishing School None of us can truthfully say that we are perfect and have nothing more to learn. Life is a school with live experiences. At our finishing school we give you the accumulated wisdom of our faculty to help you move up in your life. There are two ways to learn one by making mistakes and the other by learning before you make the mistakes. We believe that we can make a difference in your life by helping you move upward towards your goals and ambitions. Grooming in a Finishing School You learn the art of conversation, the quietly elegant as well as the flamboyant style of dress and grooming, the art of conversation, managing to live within your income, tips on saving and investment, handling aggressive behaviour with calm and poise and to manage your time effectively. This is only an outline of things and each specific need has a program to handle it. The ways of learning in a Finishing School Our programs are FUN and learning has never been so easy. Practical learning always makes for more effective retention and we follow this approach in all areas of our programs. Studies about learning methodology reveal that kinesthetic, visual and auditory learning has a better appeal and makes for better understanding. Our course modules are developed keeping these principles in mind. Age no bar for a Finishing School student A person can enrol in our finishing school at any age between 7 and 70. We believe that there are no barriers to learning. Our primary programmes are aimed at the segment seeking employment immediately or in the near future. These short-term courses help you enhance your basic knowledge and skill and give you additional inputs to make you stand out in the crowd. Programmes for children, teenagers, parents, brides and grooms and the retired person are also available in our finishing school. HISTORY OF FINISHING SCHOOLS: Switzerland is known for its private finishing schools, such as Institut Villa Pierrefeu or Institut Alpin Videmanette (now closed), where Diana, Princess of Wales studied, and Mon Fertile, where Camilla, Duchess of Cornwall was partly educated. The finishing school that made Switzerland renowned for such institutions was the Institut Villa Mont Choisi, founded in the 1870s, which closed in 1995/6. Other notable schools included Institut Chateau Beau-Cedre which closed in 2002. The term finishing school is occasionally used in American parlance to refer to certain small womens colleges, primarily on the East Coast, that were known for serving to prepare their female students for marriage. Since the 1960s, many of these schools have become defunct as a result of financial difficulties stemming from parents decreased interest in paying for such an education for their daughters. FINISHING SCHOOLS IN INDIA: Finishing School is a supplementary training school popular in India that attempts to make-up for deficiencies of low-tier colleges by providing specialized vocational training in technical fields such as computer programming and information technology. The recent boom in the Indian Economy has further enhanced the need for such finishing schools. These IT finishing schools cover technical skills as well as communication and problem solving skills. The biggest advantage of these finishing schools is that these schools cut down the deployable time for a company. Other finishing schools attempt to make up for deficiencies in the Indian secondary education system with regards to math and science education and bring the student up to the level necessary for attending university and gaining admission. For instance, it is not uncommon for Indian students to spend an entire 1 to 2 years studying in a tutorial cram school after secondary education to gain entrance into a top Medical or Engineering school. Western Countries are often flooded by extremely over-prepared and well networked Indian students, to the point of putting their own students at a disadvantage to their own rule and merit based college entrance and scholarship award systems where cram schools are virtually unknown, particular in Engineering and Medicine, areas which the Indian cram school focus on.

The result of our market survey also reflects the same scenario that the majority of the respondents prefer to join the finishing school to get fluency in English. This aspect can be taken as important opportunity for our business. Due to increasing professionalization of corporate enterprises, demand for well groomed professionals is increasing .To survive in such competitive scenario people are moving to such institutes which help them in grooming their personality and also in bringing best in them by giving their personality a complete touch. In Ghaziabad the competition level in this field being low there is a high growth opportunity available for us. We will survive and expand our business by providing best qualitative services to our customers and by maximizing their satisfaction. 1.4 FUTURE EXPANSION: Our Finishing School, Grooming Persona will constantly update its market knowledge so as to cater to the changing aspirations of our customers by providing such services as would become the paradigm of excellence for others in the same industry. In future we would like to expand our business by opening more branches of our school at various locations. And we are also thinking of having tie-ups with corporate. 1.5 FEASIBILITY STUDY: A feasibility study looks at the viability of an idea with an emphasis on identifying potential problems and attempts to answer one main question: Will the idea work and should you proceed with it? Before you begin writing your business plan you need to identify how, where, and to whom you intend to sell a service or product. You also need to assess your competition and figure out how much money you need to start your business and keep it running until it is established. Feasibility studies address things like where and how the business will operate. They provide in-depth details about the business to determine if and how it can succeed, and serve as a valuable tool for developing a winning business plan. WHY ARE FEASIBILITY STUDIES SO IMPORTANT? The information you gather and present in your feasibility study will help you: List in detail all the things you need to make the business work; Identify logistical and other business-related problems and solutions; Develop marketing strategies to convince a bank or investor that your business is worth considering as an investment; and Serve as a solid foundation for developing your business plan. Even if you have a great business idea you still have to find a cost-effective way to market and sell your products and services. This is especially important for store-front retail businesses where location could make or break your business. For example, most commercial space leases place restrictions on businesses that can have a dramatic impact on income. A lease may limit business hours/days, parking spaces, restrict the product or service you can offer, and in some cases, even limit the number of customers a business can receive each day. COMPONENTS OF FEASIBILITY STUDY legal feasibility technical feasibility human resource feasibility market feasibility financial feasibility LEGAL FEASIBILITY To define the legal and corporate structure of the business. A Legal Feasibility Study may also include professional background information about the founders and principals of the business and what skills they can contribute to the business. Legal feasibility study should include: Description of Your Business Structure Description of Your Organizational Structure Internal and External Principles and Practices of the Business TECHNICAL FEASIBILITY The Technical Feasibility Study assesses the details of how you will deliver a product or service (i.e., materials, labour, transportation, where your business will be located, technology needed, etc.). Think of the technical feasibility study as the logistical or tactical plan of how your business will produce, store, deliver, and track its products or services. A technical feasibility study is an excellent tool for trouble-shooting and long-term planning. In some regards it serves as a flow chart of how your products and services evolve and move through your business to physically reach your market. HUMAN RESOURCE FEASIBILITY It deals with the recruitment and selection of the proper kind of personnel in the various departments and also coming up with the ways of training, developing and retaining them by provision of various incentives and perks relevant to their needs and requirements. MARKETING FEASIBILITY All feasibility studies should look at how things work, if they will work, and identify potential problems. Feasibility studies are done on ideas, campaigns, products, processes, and entire businesses. Feasibility studies assess something and consider both pros and cons. They analyze potential business scenarios. A Marketing Plan maps out specific ideas, strategies, and campaigns based on feasibility study investigations that are intended to be implemented. Think of market feasibility studies as a logistical study and a marketing plan as a specific, planned course of action to take. What should be Included in a Market Feasibility Study? Things to Include in a market feasibility study include: Description of the Industry Current Market Analysis Competition Anticipated Future Market Potential Potential Buyers and Sources of Revenues Sales Projections FINANCIAL FEASIBILITY A financial feasibility study projects how much start-up capital is needed, sources of capital, returns on investment, and other financial considerations.

If this case, for starting and running a business. It considers many things including start-up capital, expenses, revenues, and investor income and disbursements.

A financial feasibility study can focus on one particular project or area, or on a group of projects (such as advertising campaigns). 1.6 WHAT IS SERVICE?

Characteristics of Service Outlet Flexibility in Consumption High Flexibility in Production Low Flexibility in consumption: Availability of different timeslots to our customers will make the consumption flexible for them. Flexibility in production: It will be low at the initial level as there are no other branches or franchises of our school so there will be only single place for delivering our services. Once we get established in the market, we are thinking of expanding our business by opening new branches of our school and also by developing web portal to provide our services.
