Hezbollah Research Paper Example | Topics and Well Written Essays - 1500 words

Hezbollah - Research Paper Example de various moves to help the Shi,ite, these measures includes: creation of academic institutes and health care institutes and was even pat of the Lebanese National Movement (Norton, 2007). Later this great leader was abducted, he was replaced by Husayn Husayni during 1979 and later the leadership of improving the conditions of Shi,ites of Lebanon was shifted in the hands of Nabih Berri (Harel, 2008). Nabih Berri ended up being a disaster for the Shi,ite Muslims of Lebanon and he wasted all the efforts made by Amal to help the Shi,ites of Lebanon. Although Musa believed that the state of Lebanon was a legal state, the other supporters of the Shi’ite population never believed that Lebanon was a legal state. The side of Shi’ite supporters which did not believe that Lebanon was a legal state, joined hands together under the control of Ayatollah Muhammad Baqir in Iraq. These individuals decided to create a covert group and named it as Hizb al-Da’wa, this group was cre ated in Lebanon. There are several reasons that led to the creation of Hezbollah, one of the reason of the development of this group was that when Lebanon came into existence during 1943, the Shi’ite Muslim population felt that they were not considered as an important part of the state and they were amongst the minorities, thus they were ready to accept and admit the creation of a group that could protect their rights (Harik, 2004). The Shi’ite population had little say in the government and their weak stand in the government was evident through the lower number of positions awarded to them in the military and the legal and the executive areas of the government. During 1946, the alliance of Christian Maronites and the Sunni Muslims were able to occupy 67% of the civilian positions within the government and the Shi’ite population was able to only occupy 3.2% of the total number of positions (Azani, 2009). During the 80s, Shi’ites population totalled to fourteen hundred tho usand, on the other

Penn State Scandal Essay Example for Free

Penn State Scandal Essay In this paper I will discuss what the ethical issue is, (and) definitions surrounding the allegations of sexual abuse, by the former Defensive Coordinator, Jerry Sandusky, who had the moral and ethical responsibility to report the incident to the proper authorities, and whether the incident was reported in a timely manner. The origin, values, ethics, honesty, and where a person grew up play an important part of an individual’s character. The definition of right and wrong varies from person to person. While I was growing up I believed that criminal justice meant an eye for an eye. As some people grow older his or her definition changed to, if an individual commits a crime, he or she should be held accountable for his or her actions. However; the punishment should fit the crime and be severe enough so the individual will learn from his or her mistake. A Pennsylvania (Penn) state assistant, Mike McQueary, claims to have witnessed Jerry Sandusky raping a ten-year-old boy in the shower (The New York Times, 2012). Sandusky (former Defensive Coordinator) was a wellrespected member of the Penn State community and good friend to Joe Paterno (former Head Coach). McQueary reported the crime immediately to Paterno. In response to the allegation, both McQueary, and Paterno reported the rape to Administrators Tim Curley (former Athletic Director) and Gary Schultz (former Vice President of Business and Finance) (The New York Times, 2012). The issue is at no time was the crime reported to police authorities. The allegation was simply brushed underneath the rug by several individuals. A crime of this magnitude should be have been reported to the proper authorities followed with legal actions. If this happens at such a prestegeous college, then what’s happening in others? I am very concerned that this may be happening somewhere else right now. I shouldn’t have to worry this, this shouldn’t be happening period. Works Cited Joe Paterno. News.

Origin And Applications Of Formwork Construction Essay

Origin And Applications Of Formwork Construction Essay Formwork is the term given to either temporary or permanent moulds into which concrete or similar materials are poured. In the context of concrete construction, the false work supports the shuttering moulds. Most of the buildings which are made to stand for a long time are made of concrete and mortar. These building materials are strongest and most suitable but at the same time they are a bit tedious to deal with. They do not acquire the desired shape and need help of some sort of support or any frame which can be detached as the concrete solidifies. Actually concrete is a material without any shape. For most applications the shape matters, and concrete has to be molded or formed. ORIGIN Concrete has been in use for the thousands of years. The dome of Pantheon in Rome is made of lightweight concrete, and the under face shows the moulding effect of formwork used two millennia ago. But it was only at the end of nineteenth century that the use of concrete became common, with the invention of reinforced concrete. Some of the earliest examples of concrete slabs were built by roman engineers. Because concrete is quite strong in resisting compressive loads, but has relatively poor Tensile strength, these early structures consisted of arches, vaults and domes. To mold these structures, temporary scaffolding and formwork built in the future shape of the structure. These building techniques were not isolated to pouring concrete, but were and are widely used in Masonry. Because of the complexity and the limited production capacity of the building material, concretes rise as a favored building material did not occur until the invention of Portland cement and reinforced concrete. Pantheon Dome SIGNIFICANCE The construction industry forms the largest single sector in any economy. In the USA for example the construction sector is responsible for 14% of the GDP (US National Statistics Bureau). Formwork is the single largest cost component of concrete buildings structural frame. The cost of formwork exceeds the cost of concrete or steel and in some situations the formwork costs more than the concrete and steel combined. For some structures, placing priority on the formwork design for a project can reduce the total frame cost by as much as 25%. This saving includes both direct and indirect costs. Formwork efficiencies accelerate the construction schedule, which can result in reduced interest costs during construction and early occupancy for the structure. Other benefits of formwork efficiency include increased job site productivity, improved safety, and reduced potential for error. Concrete is a material without shape. For most applications the shape maters and the concrete has to be molded or formed. Formwork is one of the integral parts of construction industry. This is the basic of any architectural structures on which the whole building is made. The formwork is basically used to hold the whole structure until the whole building is capable to stand on its own. Even we use some solid iron rods in buildings but the concrete need some time to bind with that for a firm structure to stand as and in the desired shape. CLASSIFICATION OF FORMWORKS Under this section of the study we will get in depth of four aspects of each and every type of the form work. These four aspects would be: Analysis of various components of formwork. Safety aspects of formwork. Economy aspects of formwork. Selection process of the material of formwork. The formworks are broadly divided in four categories based on the material, of which it is made. This categorization is as follows: Timber Formwork. Metal Formwork. Plastic Formwork. Fiber Formwork. TIMBER FORMWORK This is the oldest kind and most basic formwork used in the construction industry. Its moisture resistant property makes it utilizable in this industry. Though it is easy to manufacture the timber formwork but it is time consuming when formwork is to be prepared for big structures. It is relatively cheap and easy to shape as required. It is relatively light in weight for handling, but it is of limited durability. ANALYSIS OF VARIOUS COMPONENTS: Sheathing is supported by horizontal members called joists or runners. Joists are made from dimension lumber spaced at constant intervals that are a function of applied loads and type of lumber. It is a recommended practice to round down the calculated joist spacing to the lower modular value. Joists are supported by another set of horizontal members perpendicular to the joists, called stringers. The stringers are supported by the vertical members called shores. In all wood conventional formwork [ i.e. 4 4 in. or 6 6 in.]. Shores are rested on heavy timbers called mudsills, to transfer the vertical loads to ground. In case where a slab on grade exits, shores are directly rested on them. Once the bottom of the beam is constructed and leveled, one side of the beam is erected first with the holes drilled in it for installing the tie roads. Tie rods are steel rods that hold the two sides of beam together. After the first side of beam form is erected, the reinforcement is placed inside the beam and then the other side of the beam is erected. Tie rods are then inserted into all holes on both side of the beam. The tie rods function is to resist horizontal pressure resulting from the freshly put concrete and thus keep the sides of the beams in their proper location. SAFETY ASPECTS FOR TIMBER FORMWORK: Though Timber formwork is the basic formwork but it has some drawbacks relating to the safety which prove to be harmful for the structure to be build and the laborers. The following safety aspects must be considered while dealing with the Timber Formwork. Care should be taken in presence of Moisture: The biggest disadvantage of Timber Formwork is that the timber get softens when it is wet. If the moist is too much then timber soften up to a extent that it can be poked with the help of nail tip. Though dry timber is hard enough to bear the stress developed by concrete but it is not the same when it get wet. When timber comes in contact with moisture, the methanol molecules get activated and are responsible for weak intermolecular bond and thus softening. This problem is commonly known as Wet Rot. Care should be taken in presence of mini organisms and micro organisms: Biggest threats to any wooden structure and article are Termite and Fungus. Both of these organisms live on almost every type of wood as parasite and cause damage to huge quantity of wood. As far as Timber formwork is considered the damage occurs mainly in damp and dark regions of storage. Termites eat the wood from the inner side making it hollow and weak within. The wood thus left is so weak that it can be broken with bare hands. The damage caused by fungus is known as Dry Rot. Dry-rot fungus is often thought of as a building cancer, rampaging through buildings and rapidly destroying any timber in its path. The fungus, which thrives in moist unventilated conditions, will penetrate brickwork to get to more timber and can cause widespread destruction of structural timbers, skirting boards and door frames, and wood flooring. In short, the fungus can be thought of as living in masonry and eating wood, and because t he fungus thrives in damp, unventilated conditions, it can occur in the areas of a property that are not often seen, such as floor voids, or behind timber paneling, so damage may be extensive before the attack is discovered. Fire Safety: We already know that wood is flammable and porn to fire if considerable precautions are not taken specially for those constructions sites which are near by to a gas station or any such location. Fires on construction sites have, for many years, been recognized as a serious problem for construction companies and insurers, but less of a public safety issue since there are relatively few fire deaths in such incidents. However, the trend for ever-taller buildings, particularly in the Gulf and Far East, has resulted in a number of significant fires during construction which have caused deaths and demonstrated the difficulties facing fire brigades when tackling such incidents. On several occasions, helicopters have had to be used for fire suppression and rescue. Insurers have long had concerns about the potential for loss on tall building projects, and these fires have demonstrated that their concerns are well founded. Causes can involve electrical risks, hot work, smoking, rubbish burning, overheating equipment and escapes of gases or flammable liquids all of which are well recognized and should be amenable to normal fire safety measures. DIFFERENT TYPES OF TIMBER FORMWORK Plywood: plywood has some strength in both directions, but because the outer veneers give greater strength in the direction of their grain, the sheet should always span that way. Plywood is a few millimeters thick used as lining material, which is fully supported from behind. With thickness of 12-19 mm the strength of plywood itself can be used, and the framing members spaced out the economical distances. There are three main types of poly wood: Finnish Birch American Softwood Tropical Hardwood Sheets are normally 8ft by 4ft except for Finnish Birch, the outer grain runs in the length of the board. The first two types are produced to appropriate national standards. Hardwood ply comes from a variety of tropical countries so obtaining reliable data about them is difficult. Block board: Stripes of timber are made into a panel with veneers on both sides. The glue should be of high quality else the surface may not be flat enough as the stripes tend to show through. Block board is made up of a core of softwood strips. These strips may be up to about 25mm wide. The strips are placed edge to edge and sandwiched between veneers of hardwood. The sandwich is then glued under high pressure. Block board is not suitable for outdoor use because the glues used are interior glues. It is important to ensure that the core runs lengthways in order to achieve maximum strength. The core can be joined by hands or by machine. There are only few small core gaps or even no core gaps in machine-made core. But core gaps are common in man-made cores. Machine-made core is much better than man-made core. Block board is sold in sheets of 2440 x 1220mm and are normally 30mm thick. Screws and nails may be used to attach block board but you have to ensure that you make contact with th e strips of softwood and not the gaps between the softwood strips. Chipboard: Small chippings are pressed into sheets. As with all boards depending significantly on plastic as the matrix, the stiffness is poor, and a greater thickness than plywood is frequently needed. It is heavier than plywood but give better finish. Gluing together wood particles with an adhesive, under heat and pressure makes chipboard. This creates a rigid board with a relatively smooth surface. Chipboard is available in a number of densities: -normal, medium and high-density. METAL FORMWORK This kind of Formwork is the most suitable formwork for high rise buildings. This system is eco friendly and proves to be more economical on long run due to good durability. In the conventional metal system, joists and stringers are made of aluminum or steel supported by scaffold-type aluminum or steel shoring. In todays construction practices, joists and stringers are made of aluminum and are supported by scaffold-type movable shoring system. This formwork is built out of prefabricated modules with a metal frame (usually steel or aluminum) and covered on the application side with material having the wanted surface structure (steel, aluminum, timber, etc.). ANALYSIS OF VARIOUS COMPONENTS: In this system, steel joists and stringers have the advantage of supporting greater spans and fewer joists and stringers. The main problem with using steel as joists and stringers for forming concrete slabs is their heavy weight, which makes it difficult for one person to handle. A standard steel W-section is used because its wide flange makes it easy to connect stringers with shore legs. A composite action open-web steel joist, supporting beams and girders, and reinforced concrete slab interconnection. Upper apex portions of the steel joist webbing protrude through the upper chord members of the joist and through apertures provided in the sheet metal formwork placed over such joists prior to the pouring of the concrete slab. The improvement relates to a continuous round rod secured near the apex of each projecting web member parallel to the longitudinal axis of the joist and a reinforcing wire mesh draped between said rods, thus permitting greater spacing between said joists, whereb y said protruding apex portions, said rods and said draped wire mesh will be encased within the slab to act as shear interconnection and reinforcement devices therein, to secure the joist and formwork together, to enhance the locking of the concrete slab to the protruding joist apex portions, and to the supporting beams through the joist end connection welded to the beam or girder, and to reinforce said concrete slab. This improvement makes optional the use of wedge members forced between such protruding joist apex portions. SAFETY ASPECTS OF METAL FORMWORK Though there is no need worry for any fungal or organic decay to the metal formwork but still there are same issues which must be paid attention to, relating to corrosion and careless handling. Now lets discuss these issues one by one. Corrosion: the corrosion problem may occur to any formwork if it is not maintained in proper way. Any part of formwork may be corroded due to direct contact with moisture. This direct contact is either because of lack of proper oiling techniques or due to standing water. If even an inch or even a centimeter is left out of oiling then it proves to be dangerous for the formwork. Many times it happens that water is leaked out and left standing. This tends to corrode the dipped part of formwork. Rusting of formwork also leave stains over the concrete unit. These stains if thick, crystallize later and pose a threat to plater layer. Mishandling while assembling: There have been several cases causing accidents of laborers at the site due to mishandling of the formwork. These accidents occur while lifting, if the load is not properly tied or hydraulic jack is not applied properly. Other reason responsible for on site accidents is loose screws and bolts which lead to collapsing of the erected formwork. Electricity: If the site location is nearby any sort of electric network then the metal formwork should be handled with utmost care. A safe distance should be maintained and if possible any such network or device should be avoided in nearby vicinity of the site. DIFFERENT TYPES OF METAL FORMWORK Extruded Aluminum Joist: The first component of the conventional metal system is the aluminum joist. The extruded aluminum joist takes the shape of a modified beam with a formed channel in the top flange in which a wood nail strip 2 by 3 in. is inserted. Tha plywood deck is then nailed to the nail strip. Aluminum Beams (Stringers):The purpose of stringers is to transfer the loads of the surface panel to scaffold. Extruded aluminum joists can also be used as stringers unless the loading is too excessive, in fact it is good practice to avoid using a mixture different beam types. Aluminum beams are commercially available for the lengths ranging from 4 to 30 ft. Aluminum Scaffolding Shoring: The aluminum scaffolding shoring system has been available for several years as a substitute for the steel scaffolding shoring system. The system consists of several frames connected together by cross bracing. Aluminum shoring is lighter and has load carrying capacity equal to or greater than steel shoring. Load carrying capacity of aluminum shoring can reach up to 36,000 lb. Fig 10 Aluminum Scaffolding Shoring Post share: A Post Shore is a single member made of steel or aluminum and support stringers. Post shores can be used to replace, or in combination with, scaffold shoring. Post shores can also be used re-shoring after striping of formwork elements. ECONOMY OF FORMWORK The concrete subcontractor must achieve 3 goals in his formwork workmanship: Quality formwork must be designed and built so that the resulting cast concrete attains the desired size, shape, position and finish. Safety formwork must be designed built strong enough to support all dead and live loads without blowouts, collapse, danger to workers, and risk of damage to the structure. Economy formwork must be designed, built and re-used in an effort to save time and money for the general contractor and the owner. Now as far as the economical aspect of formwork is concerned let me make you aware of the fact that formwork share a considerable site budget. If we design the formwork intelligently and plan its use, then we can save a lot of money. As metal formwork is more durable and reusable as compared to the wooden formwork, it should be used. There are several advantages which make metal formwork a better option.

The Growing Trend of Sex and Violence in Media Today Essay -- essays r

Modern day society is composed of rules and structures. The general public has become much more sensitive over the years, resulting in a very politically correct atmosphere. Moreover, parents have decided that the opportune way of reaching their ambitions is through the lives of their children. Under this strict lifestyle, one would presume that our values are very conservative. Surprisingly, the opposite is true. Due to the sexual and violent permissiveness in today’s Multi-Media, our society has developed a sordid standard of morals. Sex is often considered to be taboo among families. Parents do not want to believe that their children are aware of it, and vice-versa. While the family is living in a state of denial, the media is embracing sexuality. It is almost impossible to go anywhere without being exposed to sexual media. Virtually all advertisements, regardless of form, use sexuality to sell their product. This ranges from beer commercials using scantily clad women to advertise their product to males, to magazines that draw our attention by writing the word â€Å"sex† in big, bold...

Colon Cancer Treatment and Prevention

As representatives of the citizens of New York State, we have a responsibility to ensure that everyone has access to the highest quality health care possible. As a State Senator. I have worked aggressively to fight for increased funding for cancer education and prevention, and to improve and expand health care coverage and treatment, including legislation we are working hard to approve — the Women†s Health and Wellness Act — which would expand treatment and prevention services and insurance coverage for breast cancer and other illnesses facing women in particular. Colon cancer is currently the second leading cause of cancer deaths, followed only by lung cancer. This year, 130,200 Americans will be diagnosed with colon cancer. Nearly half, 56,300, will die from it. Focusing on expanding treatment and coverage for colon cancer is of critical importance in our continued efforts to provide greater access to preventative health care for all citizens. Because early detection is the key in fighting colon cancer and many other illnesses, it is critically important that we continue to educate people on how they can help to prevent colon cancer – by getting a colon cancer screenings like colonoscopies. Many people are apprehensive about the test itself, which is why we must continue to advocate for quality education and prevention services. One tremendous resource we have here in our region, right here in Rochester, is the University of Rochester†s Institute of Biomedical Sciences where scientists work diligently everyday to help find more effective ways to fight cancer. As the senior member of the Rochester State Legislative Delegation, I worked with my colleagues and Governor Pataki to secure $7 million in State assistance for the Institute and will continue to fight to support these important and life-saving endeavors. Certainly I support providing our health care consumers with greater access to prevention services and more expansive insurance coverage for colon cancer treatments and would encourage everyone interested in this issue to contact their State representatives to share their views and concerns.

teleeducation essays

teleeducation essays Tele-education has a long history beginning with systems like that for teaching children in Australian Outback, the British Open University and other such organizations. These built on the idea of correspondence courses where course materials are sent periodically by post and augmented the experience with broadcasts either on radio or on TV. The problem of student isolation was addressed partially through techniques such as telephone access or two-way radio links with teachers. At the end of 1980s, the vest majority of distance education throughout the worlds was still primarily print-based. Technologies used for distance education are evolving from primarily one-way technologies and applications such as computer aided learning, computer based training and computer aided instruction, to more two-way technologies and applications such as computer mediated communications and computer conferencing systems for education. The significance of two-way technologies is that they allow foe interaction between participant and tutors, and perhaps even more significantly amongst participant themselves. This development has allowed and in some senses force researches to look more closely at the impact of educational environment, on the students learning experience. In the future, it is expected that the telecommunications-based technologies to become the primary means of delivery of distance teaching. The reasons for this are as follows: a much wider range of technologies are becoming more accessible to potential distance education participants the costs of technological delivery are dropping dramatically the technology is becoming easier to use for both tutors and learners the technology is becoming more powerful pedagogically education centers will find it increasingly difficult to resist the political and social pressures of the technological ...
