Argument Analysis 2 - Essay Example And in the third and final part, I shall assess the truth and validity of Aquinas’ argument with the help of logical reasoning. I will conclude that Aquinas’ argument is indeed a valid argument for the existence of God, based on its logical structure, but I shall argue that the entire argument is weak for it is founded upon a mere assumption. To begin with, Aquinas starts his argument by observing that there exists an â€Å"order of efficient causes† (â€Å"Summa Theologiae†). So, all events entail the existence of a prior cause, which causes its occurrence. If something is caused, then it must be caused by something other than itself. It must be caused by something other than itself, for it is logically impossible to be the cause and be caused in the same way and in the same respect. However, if something causes another thing’s occurrence, which causes the occurrence of another thing, which in turn causes another, then an order of efficient causes would entail, an infinite chain of causes. There cannot be an infinite chain of causes, for there would be no first cause. The absence of a first cause would entail the absence of a beginning from which all things began to occur. There must exist a first uncaused cause that initiated the chain of efficient causes, which is God. Therefore God exists. Given the aforementioned reconstruction, I began by claiming premise one by referring to the law of causality, which is a given in Aquinas’ argument. In premise two, the first premise is then applied to the occurrence of X, from which it was inferred, by virtue of â€Å"material implication,† that X was caused by something prior to it, that is, Y, as premise three verifies it (Copi and Cohen 395). Premise four applies the same principle, by virtue of material implication, from which it was inferred that Y was caused by something prior to it, that is, Z. However, premise five shows that this order of efficient causes lead to an infinite regress, from which

Analysis of Earthmoving Equipment

Analysis of Earthmoving Equipment Earthmoving equipment is typically used due to the high efficiency of the construction work. In early era human power has been used to move earth requiring plenty of time and manpower. But with the development of technology earthmoving equipment has been introduced to the construction field and nowadays more advanced and easily maneuverable earthmoving equipment are available. Thus the time consumption and manpower is greatly reduced resulting a more efficient and time saving construction methods. There are number of earthmoving equipment that can be used for the construction and each equipment provides a different purpose. (equipment, 2014) Excavators Figure 1: Excavator Excavators are mainly se to excavate soil. Excavators are very useful in deep excavations as well as it can be used for different applications by changing the bucket to different gadgets. Typically excavators are used in cutting trenches, digging holes and foundation pits, Handling of Material , Construction, General grading or landscaping work, Mining of minerals and gems, River dredging, pile driving, , shafts drilling for footings and blasting of rocks etc.(equipment, 2014) Backhoe Figure 2: Backhoe Backhoe is a versatile equipment which widely used in construction industry. It is a combination of an excavator and bulldozer. It can be used for quick earthmoving work and it can replace both excavator and bulldozer if the scale of the work is low. Also due to its 4 wheel system it can easily move through any rough terrain. Hence backhoe is typically seen on any construction field. The levers are operated by hydraulic pistons and the bucket can be replaced with other useful add-ons accordance to the requirement. (equipment, 2014) Bulldozer Figure 3: Bulldozer Bulldozer is a very powerful equipment which can be used to move earth and prepare surfaces. Due to its high power and belt wheel system it is used to move heavy soil lumps in one go. It has a large plate or blade attached to its front which facilitates pushing mechanism of large soil, rubble, gravel or other materials. By changing the blade to a ripper it can be used for farming or ground loosening work. Skid steer loader Figure 4: Skid Steer Loader Skid steer loader is a small scale equipment which can be used for quick work and for the places where large equipment cannot be accessible. Easily maneuverability is one of the main advantage of the equipment. Also it can be used to load soil into dump trucks. The main characteristic of this equipment is its wheel can be rotated independently allowing it to turn in limited spaces. (equipment, 2014) Trencher Figure 5: Trencher Trencher is another useful equipment that can be used to dig trenches in construction work.trencher has a long arm equipped with rotating belt of blades. The blades dig trenches while the equipment is moving along the required line. This can also be used for digging of irrigation channels, foundation trenches, road drainages etc. trenchers are also used in farming industry as well. (equipment, 2014) Motor Grader Figure 6: Motor Grader Motor grader is another useful earthmoving equipment. This equipment is heavily used in road construction. The main purpose of a motor grader is to prepare surfaces according to required slopes and angles. With the long blade attached to front arm of the equipment it can prepare flat surfaces. The motor grader is also referred to as road grader due to its heavy usage in road construction. This equipment is also used in irrigation construction as well. (History of the Bulldozer. Retrieved 2008-12-17.) For the given project I would use excavators, backhoes and Skid steer loader. The main reason for the excavator the amount of soil needs to be excavated to prepare the basement. Backhoes will be used to small scale work and slope preparation work. Skid steer loaders will be used for the small work where space is limited for big equipment. To ensure the equipment is used efficiently, effectively and economically I will preplan the earth moving process and schedule the work plan with allocating time for each equipment so that every equipment is not used at once wasting time. Also I will allocate specific tie limit for each equipment and the operator should be able to finish the allocated work within the given period of time. With such management mechanisms I can use the provided equipment effectively, efficiently and economically. What methods and resources will you employ to ensure safe and productive operations in deep excavations and trenching for your project? Justify your choice. Support your answer with examples. I will use shoring method to ensure the stability of soil while deep excavating and also a safety officer should be allocated for supervision of excavation work. Excavations will not be done on rainy days. Also the excavations will be done maintaining minimum slope angles for stability. There are several steps that need to be taken in order to assure safe and productive opertaions in deep excavations Preplanning of the work to be done taking following factors into account Traffic Proximity and physical condition of nearby structures Soil classification Surface and ground water Location of the water table Overhead and underground utilities Weather Quantity of shoring or protective systems that may be required Fall protection needs Number of ladders that may be needed Other equipment needs Protective Systems OSHA generally requires that employers protect workers from cave-ins by:   Sloping and benching the sides of the excavation; supporting the sides of the excavation; or Placing a shield between the side of the excavation and the work area. Define types of temporary works required to deal with stability and groundwater problems in the project. Typically during excavation process dewatering has to be done while maintaining stability of slopes. There are several practices used in industry maintain stability. Caissons Caisson is a structure that is developed at area if the   site is ashore, yet in the event that the venture site is seaward, it is built ashore and afterward skimmed to the site seaward. In the caisson technique for development, the unearthing is performed from inside the permanent structure. After the caisson is in position, uncovering from inside the caisson structure starts. As the unearthing is done, the caisson structure begins to sink by its own weight, or if fundamental, by forced burdens. This strategy proceeds until the coveted foundation level is accomplished. Figure demonstrates this procedure schematically. ( Wilson,1873) Figure 7: Caissons Installing Ground Freezing The theory of ground solidifying is to change the water in the soil into a strong mass of ice. This mass of ice is totally impermeable. Ground solidifying is utilized for groundwater cutoff, for earth bolster, for brief supporting, for adjustment of earth for passage removal, to capture landslides and to balance out deserted mineshafts. The principals of ground solidifying are undifferentiated from pumping groundwater from wells. To solidify the ground, a column of stop channels are set vertically in the soil and warmth vitality is expelled through these funnels. Isotherms (an isotherm is a line interfacing areas with equivalent temperature) move out from the stop channels with time like groundwater forms around a well. Once the earth temperature comes to 32  °F (0  °C), water in the soil pores swings to ice. At that point additionally cooling continues. The groundwater in the pores promptly solidifies in granular soils, for example, sands. For example, soaked sand accomplishes magnificent quality at just a couple of degrees underneath the point of solidification. On the off chance that the temperature is brought down further, the quality increments hardly. In strong soils, for example, muds, the ground water is molecularly fortified at any rate to some degree to the soil particles. On the off chance that delicate mud is chilled off to solidifying temperature, a few segments of its pore water to start to stop and it causes the earth to harden. With further decrease in temperature, more pore water solidifies and subsequently more quality pick up is accomplished. When planning for solidified earth structures in firm soils, it might be important to determine generously bring down temperat ures to accomplish the required quality, than in attachment less soils. A temperature of +20  °F might be adequate in sands, though temperatures as low as -20  °F might be required in delicate soils. The outline of a solidified earth obstruction is represented by the warm properties of the fundamental oils and related reaction to the solidifying framework. Arrangement of solidified earth boundary creates at various rates relying upon the warm and water powered properties of every stratum. Ordinarily, shake and coarse-grained soils solidify quicker than muds and sediments. (Jessica Morrison ,2013) Figure 8: Ground freezing method Dewatering Methods Wellpoints The wellpoint comprises of an opened or punctured pipe which is secured with a screen work. At the foot of this pipe is a hole which licenses flying of the pipe into the ground amid foundation. A well-point dewatering framework comprises of a progression of firmly set little distance across wells introduced to shallow profundities. These wells are associated with a pipe or header that encompasses the removal and is joined to a vacuum pump. The development ventures in the well point framework are: 1. The wellpoints are jetted into the ground; 2. The annulars void is filled with filter media; 3. The wellpoints are connected to a header pipe by means of a riser; 4. The header pipe is connected to suction pumps for pumping. Powers, J. Patrick (1992). Figure 9: Well points What types of plant and equipment will you use in substructure and drainage activities in your project? Justify your choice. Support your answer with examples. For the given project first thing that needs to do is providing drainage. While providing proper drainage by means of dewatering pumps and wells. Then to stabilize the earth proper shoring should be needed. Once the shoring is properly established further excavation and substructure work can be commenced. Drainage and dewatering Backhoes Dewatering pumps Drilling machines Hoses Generators etc. Earth stabilizing Shoring machines Cranes Welding plants Backhoes and excavators Substructure work Skid Steer loader Backhoe Excavator Piling machine What techniques of installing piling systems and ground stabilization activities will you use in your project? Justify your choice. Support your answer with examples. The foundation procedure and technique for foundations are similarly critical components as of the outline procedure of heap foundations. Pilefoundation techniques are foundation by heap mallet and exhausting by mechanical auger.In request to evade harms to the piles, amid plan, foundation Methods and foundation hardware ought to be precisely selected.If foundation is to be done utilizing pile pound, then the accompanying components ought to be taken into thought: Size of the pile and the weight of the pile The available head room and space The availability of supporting equipment and machinery The noise pollution and regulations. The driving resistance for the designed drilling Pile driving methods (displacement piles) Methods of pile driving can be categorised as follows: Dropping weight Explosion Vibration Jacking (restricted to micro-pilling) Jetting Drop hammers   Ã‚   A hammer with around the heaviness of the pile is brought a reasonable stature up in a guide and discharged to strike the pile head. This is a straightforward type of mallet utilized as a part of conjunction with light casings and test piling, where it might be uneconomical to bring a steam heater or compressor on to a site to drive extremely set number of piles. There are two main types of drop hammers 1. Single-acting pile hammers which operates using steam or compressed-air comprise a large weight in a cylindrical container. Steam or compressed air rises it up the fixed piston rod. At the top of the blow, or at a reduced height which can be operated by the operator, the steam is cut off and the cylinder falls freely on the pile helmet. 2. Double-acting pile hammers can be run by steam or compressed air. A pilling mount is not mandatory with this mode of hammer which can be fixed to the upperpart of the pile by leg-guides, the pile being directed by a timber structure. When used with a pile mount, back directs are fastened to the hammer to engage with leaders, and only short leg-guides are used to stop the hammer from moving relatively to the top of the pile. These type of hammers are used mainly for sheet pile driving. Pile driving by vibrating Vibratory sledges are normally electrically fueled or using pressurized water controlled and comprises of contra-pivoting unconventional masses inside a lodging connecting to the heap head. The abundancy of the vibration is adequate to separate the skin erosion on the sides of the heap. Vibratory strategies are most appropriate to sandy or gravelly soil. Jetting:to help the entrance of piles into sand or sandy rock, water streaming might be utilized. In any case, the strategy has exceptionally restricted impact in firm to solid muds or any dirt containing much coarse rock, cobbles, or stones. Boring methods (non-displacement piles) Continuous Flight Auger (CFA) Hardware contains a portable base transporter fitted with an empty stemmed flight wood screw which is pivoted into the ground to required profundity of pilling. To shape the heap, cement is put through the flight twist drill as it is pulled back from the beginning. The twist drill is fitted with defensive top on the outlet at the base of the focal tube and is pivoted into the ground by the top mounted turning pressure driven engine which keeps running on a transporter joined to the pole. On achieving the required profundity, profoundly workable cement is pumped through the empty stem of the wood screw, and under the weight of the solid the defensive top is disconnected. While pivoting the wood screw in an indistinguishable bearing from amid the exhausting stage, the ruin is removed vertically as the twist drill is pulled back and the heap is shaped by loading with cement. In this procedure, it is essential that pivot of the wood screw and stream of cement is coordinated that fall of sides of the opening above cement on lower flight of twist drill is evaded. This may prompt to voids in loaded with soil in cement. The strategy is particularly viable on delicate ground and empowers to introduce an assortment of exhausted heaps of different widths that can infiltrate a large number of soil conditions. Still, for fruitful operation of revolving twist drill the dirt must be sensibly free of tree roots, cobbles, and stones, and it must act naturally supporting. Amid operation little soil is brought upwards by the twist drill that horizontal burdens are kept up in the dirt and voiding or extreme slackening of the dirt limit. Be that as it may, if the pivot of the wood screw and the progress of the twist drill are not coordinated, bringing about evacuation of soil amid penetrating perhaps prompting to fall of the side of the gap. Figure 10: Piling and Auguring Underreaming An extraordinary component of wood screw exhausted heaps which is here and there used to empower to misuse the bearing limit of appropriate strata by giving a developed base. The dirt must be fit for standing open unsupported to utilize this method. Firm and to hard muds, for example, the London dirt, are perfect. In its shut position, the underreaming instrument is fitted inside the straight area of a heap shaft, and after that extended at the base of the heap to create the underream appeared in fig. 3.Normally, after establishment and before cement is threw, a man conveying enclosure is brought down and the pole and the underream of the heap is reviewed. (Fleming et al, 1985,) What methods and processes of constructing foundations including will you use in your project? Justify your choice. Describe the resources that you will use for the construction of foundations. Justify your choice. In the event of soils having low bearing limit, overwhelming auxiliary burdens are generally bolstered by giving Raft or tangle establishments. Likewise if the structure is defenseless against subsidence on being situated in mining range or because of questionable conduct of its sub-soil water condition, flatboat or tangle establishments ought to be favored. Raft or Mat Foundations gives an efficient answer for troublesome site conditions, where heap establishment cant be utilized profitably and free section balance gets to be distinctly impracticable. Raft or tangle establishments comprises of thick fortified solid slab covering the whole range of the base of the structure like a story. The piece is strengthened with bars running at right points to each other both close base and top face of the section. Now and again it is important to convey the over the top section stack by a course of action of reversed principle shafts and auxiliary bars, cast solidly with the flatboat piece. The Raftslab for the most part ventures for a separation of 30 cm. to 45cm. on every one of the sides of the external dividers of the structure in that capacity the region of exhuming is marginally more than the range of the structure itself. The unearthing is made to the required profundity and the whole uncovered territory is very much united. This surface, when dry, gives the base whereupon the flatboat or tangle section is laid. Every one of the precautionary measures that are important to be seen amid the strengthened solid development are entirely clung to and promote development is begun simply after the curing of the Raft has been completely done.Halpin, Daniel W.; Senior, Bolivar A. (2010). Describe methods and resources that you will use in processes, undertaking drainage works including culverts and installing services in your project. Culverts and drainage works Excavation The area of the proposed drainage will be set out on the ground by checking with paint and pegs at pit areas. Where works are along edge of existing roadway movement light or stop/go framework might be set up to do works. A trench will then be unearthed between pits utilizing an excavator with material stacked to dump truck. The trench width will differ contingent upon the measure of the pipe. Installation Where drains are being introduced a layer of geotextile material should be put along the framework of the trench and a layer of channel stone might then be put in base of trench to get pipe work. The pipe work should then be laid to the right line and level by utilizing a review laser Backfilling of Ducting The remaining stone might then be put by six ton dumper up to underside of topping where geotextile should be turned out under topping layer. The rest of the depleted might be bested up once surfacing works are done up to wearing course level. Establishment of layer of Geogrid should likewise be done at this stage. All chambers on the deplete lines might be built with pre-thrown solid catch pits and should be put as pipeline continues. (Turner-Fairbank Highway research Center ,1998) Figure 12: Culverts What types of plant and equipment will you use in the construction of superstructure your project? Justify your choice. Support your answer with examples. Construction of superstructure requires lot of machinery and equipment and the uses may vary throughout the different stages of the project. Following are a list of equipment and the uses of each equipment. Equipment Uses Batching plant Concrete Production Concrete pump Concrete pouring to higher levels Tower crane Shifting materials Elevator Shifting materials and laborers Formwork systems Form the structure Scaffolding For higher level work Poker vibrator For compaction of concrete The batching plant will produce concrete required to construction and concrete mixture truck and pump will support to pour concrete to slabs, columns and beams. Tower crane and elevator will help to move goods and laborers respectively. Scaffoldings, formwork systems and poker vibrator will be used for concrete pouring and form the columns, slabs and beams of the building. What methods and resources will you use in undertaking the main forms of structural activities in you project? Include the use of concrete in its various forms as well as the use of structural steelwork. Provide relevant examples. Justify your choices. Mainly concrete will be used together with steel to form the superstructure. Typically formwork will be established first and then concrete together with steel will be used to cast columns, beams and slabs of the building. For the aforementioned task concrete pumps, poker vibrators, laborers and skilled supervisors will be needed. Concrete is typically used for this type of construction work due to its workability. Liquid state of concrete allows us to cast different required shapes and forms of structures with ease. Whereas steel is a pre-fabricated material hence steel does not provide the freedom to use for different shapes. But steel is also a very good construction material which facilitates fast construction. Structural steelwork can be used together with concrete to produce composite structures. Also steel can be used alone for buildings as well. (Concrete Association, 2013) What methods of false work and formwork will you use in the superstructure activities in your project? Provide examples. Justify your choice. What processes of concrete production, delivery and placement will you use in your project? Justify your choice. Formwork implies the surface of the frame and surrounding used to contain and shape wet cement until it is self-supporting. Formwork incorporates the structures on or inside which the solid is poured and the casings and propping which give soundness. Albeit ordinarily alluded to as a component of the formwork get together, the joists, bearers, propping, establishments and footings are actually alluded to as false work. Formwork development may include high hazard exercises like working fueled portable plant like cranes, working at stature and unearthing establishments. The outline of the last solid structure can majorly affect the simplicity of formwork development and the wellbeing and security of individuals amid development. For the most part the more essential and basic the last solid structure, the more secure it is to develop, erect and destroy the formwork. An accomplished formwork creator ought to be counseled amid the plan of in-situ solid structures to empower the wellbeing and dangers amid formwork development and destroying to be considered in the outline. The formwork originator must be equipped in formwork configuration including reporting brief work stages and exceptional gear required for safe formwork development on location. A creator may utilize a specialized standard or a blend of gauges and building standards significant to the plan prerequisites the length of the result is an outline that meets administrative necessities. Concrete production Concrete Batching plant Concrete will be produced in a batching plant to ensure the quality and strength of the concrete. Concrete Delivery Mixture truck Mixture trucks will be used to deliver concrete to the site from the batching plant to prevent loss of workability and quality of concrete Concrete Placement- Concrete pump truck Concrete will be placed to higher levels using a concrete pumping truck. This way we can efficiently pour concrete.   (Concrete Association, 2013) Identify and assess the hazards arising from the substructure activities. Falling of unstabilized soil Falling to deep excavated trenches and pits Hazards associated with excavators Shorings can be weak Damages to underground electrical wires Explain the legal framework of health, safety and welfare and the requirements of the current CDM Regulations. The Construction (Design and Management) Regulations 2015 (CDM 2015) addresses the management of health, safety and welfare of workers in construction projects. CDM 2015 substituted the Construction (Design and Management) Regulations 2007 (CDM 2007) and the Accepted Code of Practice which is providing supporting direction on CDM 2007 was inhibited. CDM 2015 aims to uplift health and safety in the industry by providing guidance to: Rationally plan the work so the risks tangled are succeededthroughout. Have the correct people for the correct job at the correct time collaborate and organize your work have the properinfo about the risks and how they are managed convey information efficiently to those who need to know consult and occupy workers for the risks management activities and educate them how they are being managed The CDM2007 Regulations expect to lessen development mischances and sick wellbeing in Great Britain by empowering the different partners of the development business to enhance in arranging and dealing with their activities contemplating matters of security and wellbeing at an early stage in the venture definition. By beginning concentrating on these basic focuses toward the start of a venture, dangers can be recognized and supervisors can use sound judgment in front of challenges. In this new form of the directions, the HSC concentrates on correspondence and co-appointment between every one of the gatherings required in the development venture and set up a few obligations for each of the distinctive partners. It likewise highlights that the measure of printed material and all the administration brought on by the past rendition of the controls ought to be diminished and the attention put on the arranging and administration. The CDM set up commitments for customers and fashioners. The fundamental commitment forced to the customer is to delegate the primary partners for the arranging and the acknowledgment of development work. By development work, the CDM extensively alludes to the doing of building, structural designing or building development word .Among the dutyholders which take an interest to the doing of the venture are the Client, the Designer, the CDM-Coordinator, the Principal Contractor and the Contractors. (The Construction (Design and Management) Regulations ,2007) Evaluate and justify the role of the planning coordinator who has been appointed to the project. Construction project coordinators plan, organize, and guide the actions of a construction project, under the guidance of a manager. He works on-site most of the time, over looking the day-to-day tasks of the project. He works for residential, commercial and industrial construction companies or for construction departments of companies outside the construction industry. Generally, construction project coordinators: Make contracts and negotiate alterations to contracts with architects, consultants, clients, suppliers, and subcontractors. Suggest and implement QC programs. Make progress reports for clients. Control the acquisition of building materials and land. Hire and supervise subcontractors and staff. During the excavation works the contractor found that the sub-soil in a section of the site to be contaminated. All site activities were halted pending further investigations. Following the investigations it was found that the site was contaminated with caustic soda and from material linked to buried heavy fuel tanks. The client has asked for a design solution to the problem. The contaminated ground can be treated with 5% ferric chloride treat the caustic soda contamination. Proper waterproofing of basement can further ensure that the caustic soda intrusion is completely blocked. Burried heavy fuel tanks should be properly sealed to prevent further leakages. If the contaminated section can be completely removed it should be removed and disposed safely to continue construction work. (Risk Assessment Guidance for Superfund, Human Health Evaluation Manual) Produce a risk assessment for the above problem. Hazard identification Caustic Soda and Heavy fuel Contamination. Laborers and stakeholders can be affected Sub soil needs to be treated or removed

Biosphere 2 :: Papers

Biosphere 2 Biosphere 2 is a supersealed â€Å"greenhouse† enclosing an area of 3.15 acres. Exit and entry is through a double airlock. It consists of several different ecosystems within the â€Å"greenhouse.† It houses a tropical rainforest, savannah, scrub forest, desert, fresh- and salt-water marshes and a miniocean that even contains a coral reef. This biosphere is inhabited by over 4000 species in all. The biosphere is able to preserve it environment because; water vapor from evaporation and transpiration of plants is condensed to produce high amounts of rainfall over the tropical rainforest. From there the water runs back towards the marshes and ocean as is filters through the soil, providing for an ample supply of fresh water for the humans as well as the ecosystems. The carbon dioxide released from respiration is absorbed for photosynthesis and necessary oxygen is replenished. Thus, meeting the necessary requirements for a sustainable biosphere. Biosphere 2 is not completely self-sufficient, it does depend on solar energy, and the energy demands that are created to power the necessary machinery, would require another 30 acres of solar collectors. The conclusion of the â€Å"cycle† is that not everything went exactly as planned. The oxygen level at one point dropped and additional oxygen had to be added to compensate for the underestimated amount of oxygen used by the decomposers in the soil. Larger amounts of carbon dioxide were used because of chemical reactions with exposed concrete. A large number of the species introduced especially insects necessary for pollination, died off, requiring pollination of many plants by hand. Despite these drawbacks the water, soil, and nutrients they started with were the same as when finished, having gone through the cycle a countless number of times. We have learned from this experiment that it is possible to build a biosphere, that integrates humans, and have it function within the tolerable limits of sustainability. Future versions of this experiment may be used in constructing permanent space stations or for long distance space exploration. If we continue mistreating our present biosphere we may end up living in structures similar to Biosphere 2. In my opinion this experiment proved to be very valuable if we wish to set up colonies on the Moon or other planets. This experiment is the beginning of the necessary information that will be needed to construct a completely self-sufficient biosphere.

Disaster Paper Essay

When you deliberate on a disaster, it becomes clear that any such event has three phases to it. Initially, there are antecedents that lead to the disaster. When enough antecedents have accumulated, the disaster occurs at that specific tipping time. Finally after the disaster has happened the final phase of resolutions occurs. The resolutions are steps that the society attempt to implement to revert the effects that the event has produced. Consider the Deepwater Horizon disaster that happened on July 17th 2010. Upon critical review the group have identified series of antecedents that led to the disaster. At the tipping point the disaster occurred, lives were lost and numerous crew members injured. After the initial shock of the disaster and evacuation of the crew engineers and BP staff attempted to close the well with numerous trials. Eventually policy makers were involved in development of the new safety policies. Numerous investigations and trials were performed to better understand the disaster and avoid similar events. At the end numerous antecedents have been identified, the disaster was resolved and the consequences identified. The Deepwater Horizon accident was found to have multiple antecedents that caused this tragedy. Specifically, a sequence of eight safety barriers that were breached led to the explosion which killed eleven people and caused widespread pollution throughout the Gulf of Mexico. At first the annulus cement barrier was installed improperly and did not isolate the hydrocarbons coming from the well. The shoe track barrier did not isolate the hydrocarbons. As a consequence these two events allowed hydrocarbons to rise up the well and aboard the Deepwater Horizon rig. The negative pressure test was incorrectly interpreted. The influx of hydrocarbons was not recognized until it was too late. Well control response actions failed to regain the control of the well. This led the well flow to be diverted to the mud gas separator causing gas to be vented onto the vessel rather than being diverted over board. Safety fire and gas systems did not prevent hydrocarbon ignition from the engine room. Finally, the blowout preventer (BOP) emergency modes did not seal the well due to the accumulation of previous seven events mentioned above. With these eight events leading one to another, it was much more difficult to seize the explosions and fire that damaged the MUX cables and hydraulic lines. This resulted in failure of the emergency disconnect system. To conclude, it is clear that specific and identifiable antecedents can be discovered and that their accumulations to a tipping point lead to the disaster. The second phase of the Deepwater Horizon disaster deals with engineers and BP technical staff trying to close the well so that the oil spill is stopped. To reduce the oil spill the leaking oil is set on fire with the hope that the spill will be reduced. On May 2nd, 2010 PB starts to drill a relief well that should overtake that leaking site. On May 5th one of the leaking sites is capped, however oil continues to leak from the well. On May 7th BP engineers use the containment chambers to close the remaining leaks. The idea fails and is abandoned. On May 9th a â€Å"junk shot† approach is implemented, the following day â€Å"top hat† approach is planned out. The attempt to reduce the leak continues, numerous other approaches and plans are implemented to either reduce the oil spill or completely halt it. On august 4th BP reports that using the latest attempt the â€Å"static kill† appears to be successful and attempts to permanently seal the leak are in the process. On September 19th the Deepwater Horizon leak have been permanently sealed. The nightmare that happened on May 2nd has been halted but not fully resolved. The environmental affect that the disaster caused will hunt the future of Gulf of Mexico waters for decades. For example, seahorse populations in the region decline and the Hippocampus zosterae, dwarf specie of seahorses, is on the verge of extinction. The role of engineers in the Deepwater Horizon disaster is immense. During the accumulation of antecedents there are evidences that engineers knew about chaos that was occurring on the Deepwater Horizon rig. However, due to poor management and lack of communication between companies involved in the project, engineers had little impact in correcting the antecedents. Eventually, when the disaster occurred, the BP engineers tried various attempts and ideas to close the opened well. Lastly environmental engineers are and will be involved in cleaning efforts of the Gulf of Mexico waters. Therefore it is important to consider the engineers as not only the antecedents in a disaster but also as proactive members of society that attempt fixing the environment to pre-disaster state. Therefore, engineering is involved with all disaster phases. As a group, we plan to incorporate each disaster phase into the final report and discuss how engineering process have been aiding the future avoidance of similar disasters. It is important to understand that media reports cover just a few aspects of disasters and news in general. In many cases the scope of media reports is within political and economic spectrums. Therefore further research into documents released by various commissions and investigators that are publicly available will be looked at and analysed by the group and its members. The group process is moving according to the milestones developed and outlined in the proposal paper. Despite this, new opportunities in scheduling allows for the group to have a few extra meetings and perhaps finish the final report ahead of the scheduled time. The comparison chart of milestones is outlined below. Over all there are a few challenges that the group have to work through. As mentioned above the group plans to analyze some reports developed by the investigators of the disaster. The challenging part is to read through pages of technical analysis and to identify related parts for the assignment. Since there are new group meetings, it should be possible to accomplish this task in professional manner. In addition the group will do a presentation on the project therefore these two meeting dates will be allocated towards that time. The final paper will contain a more detailed and chronological outline of the disaster phases. The paper will discuss the causes, antecedents and policy developments that occurred as of the result of the disaster. The general breakdown of the parts has not changed since they were assigned during the composition of the proposal paper.

Impact of Globalisation on Education Essay

The effects of globalisation on education bring rapid developments in technology and communications are foreseeing changes within learning systems across the world as ideas, values and knowledge, changing the roles of students and teachers, and producing a shift in society from industrialisation towards an information-based society. In the research paper an effort is made to highlight the positive and negative implications of Globalisation on education and also remedies to the challenges faced by it. On moving towards its positive aspects it is evident that due to globalization there is explosion of knowledge. Access to knowledge has been made easier through Information Technology, satellites, supersonic travel etc, No country can afford to erect walls around it. A country like India for example, has no reason to discard globalisation because it has a large potential for natural resources, large national market, strong industrial base, a powerful R & D infrastructure and above all a highly knowledgeable and skilled manpower that can stand on its own in global competition and rise to any challenge. Employment based education was the most precious gift of gobalisation. Education can be globalised in three ways: (i) By setting up educational campuses abroad, (ii) By offering educational programmes in foreign countries through tie-ups or collaborations with their educational institution, and (iii) By admitting foreign and NRI students in our educational institutions. On moving towards its darker side, there are many challenges faced by our education system. Due to commercialization of education it creates a divide between ‘haves’ and ‘havenots’. As education came in the reach of privates institutions it is going out of reach of poor. Moreover, the quality of education imparted in private and govt. nstitution have the difference of sky and earth. Quality of education in govt. institution is degrading and private institutions are beyond the reach. What a pity! Many foreign institutions and other private institutions are merely degree delivering machines. The objective of education from knowledge sharing is shifting merely to p rofit maximizing. This is a degradation in the values of Indian education system which has the glory of ‘Vishw Guru’ and where the concept of gurukul and teacher-student relationship exists but today that respect of student towards teacher and even the dedication and care of teacher towards student is missing. Along with all these, the increase craze of medical, engineering and business administration and downfall in plain courses of science, commerce and arts has only resulted in many doctors ,engineers and MBA students not recognized and no longer produces efficient and honest administrators which is a die-heart need in country like India which is in the grip of cancerous corruption. Looking to all its positivity and negativities the attempt in the research paper is to explore the remedies to the challenges faced by education . To make globalization meaningful and productive, we need to design a system of education that is universal, affordable, based on the principles of justice and related to the life of the community. This new universal system of education must incorporate social and moral values in its curriculum and produce world citizens who are free from prejudices and who are the builders of an ever advancing civilisation.

Essay What Causes Love at First Sight

Essay What Causes Love at First Sight Essay: What Causes Love at First Sight? The concept of love at first sight is one that continues to be a debatable topic, because of the many controversial issues about love in the present day. A good source of primary information on factors that cause someone to fall in love at first sight is those who profess to have fallen in love with their significant other upon meeting them for the first time. One of the issues these individuals may state is when they first came into their significant others presence, they felt a tingling effect all over their bodies that made them excited to be at the same place as the person they were attracted to and had fallen in love with. The difference with the excitement of falling in love at first sight is that the sensation is stronger than they had experienced before, when they were infatuated with another individual. The whole feeling of falling in love is highly emotional, because couples that have reported falling in love report having a strong emotional connection with their significant other. These couples also report getting to know more about the person they fell in love with in a shorter amount of time than when they got to know their other friends. Falling in love makes people want to know more about a significant other than those who they have spent a very long time knowing. One other interesting thing about falling in love at first sight is the feeling that one gets makes him or her want to profess their love to that individual the very first time they meet. The unwritten rule of love emphasizes that one should profess one’s loves to the other individual after a couple of dates, as well as after both parties feel they have known the other individual enough to be very comfortable around one another. Love at first sight; however, makes one feel like saying he or she loves the other individual even before really getting to know the other individual. When one falls in love at first sight, one gets preoccupied with the other individual just hours after meeting the individual and always wants to spend a significant amount of time with that individual. One may also feel like telling the other individual everything about themselves. When one falls in love with another individual, the relationship with the other individual seems very easy to pursue and one finds it very easy to put up with the individual’s weaknesses. Those who fall in love quickly usually state they get worried or are deeply concerned about their significant other shortly after they have met that individual for the first time.

spectrophotometery essays

spectrophotometery essays The purpose of this lab experiment is to understand the uses of spectrophotometry. This experiment concentrates on the uses of the spectrophotometer, and using this instrument to specifically determine the absorption spectrum of a cobalt chloride solution, a galactose solution, and to determine an unknown concentration of a galactose solution. Modern biologists frequently use the measurement of light absorption to determine concentration of chemicals. The technique is called spectrophotometry. However, why is light absorbed? Light may be simply scattered by particles, but this is extremely important to the measurement of truly absorbed light. Light is the part of electromagnetic radiation to which the human eye is sensitive. Light is energy, and when absorbed by a chemical it results in a change in energy levels of the chemical. The energy of light depends on its wavelengths. Longer wavelengths, such as infrared, have less energy than shorter wavelengths, such as ultraviolet. A molecule will absorb light energy when a wavelength exactly matches the energy difference between two energy states of the molecule. A spectrophotometer makes use of the transmission of light through a specific solution to determine the concentration of a solute within a solution. It is based on a simple design of passing light of a known wavelength through a sample and measuring the amount of light energy that is transmitted. The design of a single beam spectrophotometer involves a light source, a prism, a sample holder, and a photocell. Connected to each are the appropriate electrical or mechanical to control the illuminating intensity, the wavelengths, and for conversion of energy received to readable data that can be recorded, which is known as a voltage fluctuation. This voltage fluctuation is displayed digitally and recorded for further analysis. The whole idea of spectrophotometery determining the concentration of a compound is ba...
