Analysing Types Of Collection System Engineering Essay

Analysing Types Of Collection System Engineering Essay Based on their mode of operation, collection systems are classified into two categories: hauled-container systems and stationary-container systems. Hauled-Container Systems (HCS): Collection systems in which the containers used for the storage of wastes are hauled to the processing, transfer, or disposal site, emptied, and returned to either their original location or some other location are defined as hauled-container systems. There are two main types of hauled-container systems: (1) tilt-frame container and (2) trash-trailer. The collector is responsible for driving the vehicle, loading full containers and unloading empty containers, and emptying the contents of the container at the disposal site. In some cases, for safety reasons, both a driver and helper are used. Systems that use tilt-frame-loaded vehicles and large containers, often called drop boxes, are ideally suited for the collection of all types of solid waste and rubbish from locations where the generation rate warrants the use of large containers. Open-top containers are used routinely at warehouses and construction sites. Large containers used in conjunction with stationary compactors are common at commercial and industrial services and at transfer stations. Because of the large volume that can be hauled, the use of tilt-frame hauled container systems has become widespread, especially among private collectors servicing industrial accounts. The application of trash-trailers is similar to that of tilt-frame container systems. Trash-trailers are better for the collection of especially heavy rubbish, such as sand, timber, and metal scrap, and often are used for the collection of demolition wastes at construction sites. Stationary-Container Systems (SCS): Collection systems in which the containers used for the storage of wastes remain at the point of waste generation, except when moved for collection are defined as stationary-container systems. Labor requirements for mechanically loaded stationary-container systems are essentially the same as for hauled-container systems. There are two main types of stationary-container systems: (1) those in which self-loading compactors are used and (2) those in which manually loaded vehicles are used. Because a variety of container sizes and types are available, these systems may be used for the collection of all types of wastes. The major application of manual transfer and loading methods is in the collection of residential wastes and litter. Manual methods are used for the collection of industrial wastes where pickup points are inaccessible to the collection vehicle. Collection Routes: Once the equipment labor requirements have been determined, collection routes must be laid out so both the work force equipment are used effectively. In general, the layout of collection routes is a trial-and-error process. There are no fixed rules that can be applied to all situations. Some of the factors that should be taken into consideration when laying out routes are as follows:(1) existing company policies and regulations related to such items as the point of collection and frequency of collection must be identified, (2) existing system conditions such as crew size and vehicle types must be coordinated, (3) wastes generated at traffic-congested locations should be collected as early in the day as possible, (4) sources at which extremely large quantities of wastes are generated should be serviced during the first part of the day, and (5) scattered pickup points where small quantities of solid wastes are generated should, if possible, be serviced during one trip or on the same day, if they receive the same collection frequency. Layout of Routes: The layout of collection routes is a four-step process. First, prepare location maps. On a relatively large-scale map of the area to be serviced, the following data should be plotted for each solid-waste pickup point: location, number of containers, collection frequency, and, if a stationary-container system with self-loading compactors is used, the estimated quantity of wastes to be collected at each pickup location. Second, prepare data summaries. Estimate the quantity of wastes to be collected from pickup location serviced each day that the collection operation is to be conducted. Where a stationary-container system is used, the number of locations that will be serviced during each pickup cycle must also be determined. Third, lay out preliminary collection routes starting from the dispatch station or where the collection vehicles are parked. A route should be laid out that connects all the pickup locations to be serviced during each collection day. The route should be laid out so that the last location is nearest the disposal site. Fourth, develop balanced routes. After the preliminary collection routes have been laid out, the haul distance for each route should be determined. Next, determine the labor requirements per day and check against the available work times per day. In some cases it may be necessary to readjust the collection routes to balance the work load and the distance traveled. After the balanced routes have been established, they should be drawn on the master map. Schedules: A master schedule for each collection route should be prepared for use by the engineering department and the transportation dispatcher. A schedule for each route, on which can be found the location and order of each pickup point to he serviced, should he prepared for the driver. In addition, a route book should be maintained by each truck driver. Transfer and transport: The functional element of transfer and transport refers to the means, facilities, and appurtenances used to effect the transfer of wastes from relatively small collection vehicles to larger vehicles and to transport them over extended distances to either processing centers or disposal sites. Transfer and transport operations become a necessity when haul distances to available disposal sites or processing centers increase to the point that direct hauling is no longer economically feasible. Transfer Station: Important factors that must be considered in the design of transfer stations include: type of transfer operation to be used, (2) capacity requirements, (3) equipment and accessory requirements, and (4) environmental requirements. Type of Transfer Station: Depending on the method used to load the transport vehicles, transfer stations may be classified into three types: direct discharge, storage discharge, and combined direct and storage discharge. Direct Discharge: In a direct-discharge transfer station, wastes from the collection vehicles usually are emptied directly into the vehicle to be used to transport them to a place of final disposition. To accomplish this, these transfer stations usually are constructed in a two-level arrangement. The unloading dock or platform from which wastes from collection vehicles are discharged into the transport trailers is elevated, or the transport trailers are located in a depressed ramp. Direct-discharge transfer stations employing stationary compactors are also popular. Typical direct discharge transfer station Storage Discharge: In the storage-discharge transfer station, wastes are emptied either into a storage pit or onto a platform from which they are loaded into transport vehicles by various types of auxiliary equipment. In a storage-discharge transfer station, the storage volume varies from about one-half to two daysà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢ volume of wastes. Typical storage discharge transfer station Combined Direct and Storage Discharge: In some transfer stations, both direct-discharge and storage-discharge methods are used. Usually, these are multipurpose facilities designed to service a broader range of users than a single-purpose facility. In addition to serving a broader range of users, a multipurpose transfer station can also house a materials-salvage operation. Capacity Requirements: The operational capacity of a transfer station must be such that the collection vehicles do not have to wait too long to unload. In most cases, it will not be cost- effective to design the station to handle the ultimate peak number of hourly loads. An economic trade-off analysis should be made between the annual cost for the time spent by the collection vehicles waiting to unload against the incremental annual cost of a larger transfer station and/or the use of more transport equipment. Because of the increased cost of transport equipment, a trade-off analysis must also be made between the capacity of the transfer station and the cost of the transport operation, including both equipment and labor components. Equipment and Accessory Requirements: The types and amounts of equipment required vary with the capacity of the station and its function in the waste-management system. Specifically, scales should be provided at all medium and large transfer stations both to monitor the operation and to develop meaningful management and engineering data. Environmental Requirements: Most of the large, modern transfer stations are enclosed and are constructed of materials that can be maintained and cleaned easily. For direct-discharge transfer stations with open loading areas, special attention must be given to the problem of blowing papers. Wind screens or other barriers are commonly used. Regardless of the type of station, the design and construction should such that all accessible areas where rubbish or paper can accumulate are eliminated. Location of Transfer Station: Whenever possible, transfer stations should be located (1) as near as possible to the weighted center of the individual solid-waste production areas to be served, (2) within easy access of major arterial highway routes as well as near secondary or supplemental means of transportation, (3) where there will be a minimum of public environmental objection to the transfer operations, and (4) where construction and operation will be most economical. Additionally, if the transfer- station site is to be used for processing operations involving materials recovery and/or energy production, the requirements for those operations must be considered. Transfer Means Methods: Motor vehicles, railroads, and ocean-going vessels are the principal means now used to transport solid wastes. Pneumatic and hydraulic systems have also been used. Motor Vehicle Transport: Motor vehicles used to transport solid wastes on highways should satisfy the following requirements: (1) the vehicles must transport wastes at minimum cost, (2) wastes must be covered during the haul operation, (3) vehicles must be designed for highway traffic, (4) vehicle capacity must be such that allowable weight limits are not exceeded, and (5) methods used for unloading must be simple and dependable; The maximum volume that can be hauled highway transport vehicles depends on the regulations in force in the state in which they are operated. Methods used to unload the transport trailers may be classified according to whether they are self-emptying or require the aid of auxiliary equipment. Self-emptying transport trailers are equipped with mechanisms such as hydraulic dump beds, powered diaphragms or moving floors that are part of the vehicle. Moving-floor trailers are an adaptation of equipment used in the construction industry. An advantage of the moving-floor trailer is the rapid turnaround time (typically 6 to 10 mm) achieved at the disposal site without the need for auxiliary equipment. Unloading systems that require auxiliary equipment are usually of the à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€¦Ã¢â‚¬Å"pull-offà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ã‚  type, in which the wastes are pulled out of the truck by either a movable bulkhead or wire-cable slings placed forward of the load. The disadvantage of requiring auxiliary equipment and work force to unload at the disposal site is relatively minor in view of the simplicity and reliability of these metho ds. Another auxiliary unloading system that has proved very effective and efficient involves the use of movable, hydraulically operated tipping ramps located at the disposal site. Operationally, the semitrailer of a tractor-trailer- trailer combination is backed up onto one of the tipping ramps; the tractor-trailer combination is backed up onto a second tipping ramp. The backs of the trailers are opened, and the units are then liked upward until the wastes fall out by gravity. The time required for the entire unloading operation typically is about 5 mm/trip. Large-capacity containers and container trailers are used in conjunction with stationary compactors at transfer stations. In some cases, the compaction mechanism is an integral part of the container. When containers are equipped with a self-contained compaction mechanism, the movable bulkhead used to compress the wastes is also used to discharge the compacted wastes. Railroad Transport: Although railroads were commonly used for the transport of solid wastes in the past, they are now used by only a few communities. However, renewed interest is again developing in the use of railroads for hauling solid wastes, especially to remote areas where highway travel is difficult and railroad lines now exist. Water Transport: Barges, scows, and special boats have been used in the past to transport solid wastes to processing locations and to seaside and ocean disposal sites, but ocean disposal is no longer practiced by the United States. Although some self-propelled vessels (such as United States Navy garbage scows and other special boats) were once used, the most common practice was to use vessels towed by tugs or other special boats. Pneumatic Transport: Both low-pressure air and vacuum conduit transport systems have been used to transport solid wastes. The most common application is the transport of wastes from high-density apartments or commercial activities to a central location for processing or for loading into transport vehicles. The largest pneumatic system now in use in the United States is at the Walt Disney World amusement park in Orlando, Florida.

A book review on “The Mountain People” by Colin Turnbull Essay

Turnbull has been quoted as a renowned ethnographic on writing about small-scale societies which lead a peaceful life in a trouble-free atmosphere by maintaining the size of their population and enjoyed a pollution-free environment till they are polluted by progress. In this book, Turnbull is describing about Ik tribal people who lived in the northern parts of Uganda and near to the border of Kenya who had to leave their ancestral villages as the area had been declared as a national park later. Due to this, Ik people had to live in non-fertile area which was affected by drought and famine almost several years in a series. [p. 117] and today, it is evident that Ik are facing a total negation of society. The specialty of Turnbull is that the style which the book is presented as he just narrated what he had seen and observed in the Ik province without adding colors or adding his own judgment on the scenery. See more: Experiment on polytropic process Essay Turnbull tries to give an anthropologist’s bird’s view on Ik’s style of living and conditions of their life by establishing close contact with Ik community and with communities lived in the neighborhood. Turnbull while living with Ik’s witnessed continuous cattle raids and how their children had been deserted by the parents even at the age of three and how the youths robbed the food-stuffs from the elders thereby making them to die prematurely. The Mountain People deals with the ethnographic details of the Ik or Teuso people living in northern Uganda. Turnbull in this book tries to expose how society and small-scale societies in general have been pretentious. In this book , Turnbull ties to portray the Rousseauesque picture of gatherers , hunters in general and Pygmies in specific , narrating generosity , kindness , honesty ,affection , charity ,compassion and other virtues available in them [p31]. [Spencer 651]. Due to progress, Ik have been compelled to leave their nomadic life and forced to peruse agriculture and illegal poaching. From 1965 onwards, innocent and gullible Ik have developed qualities like envy, acrimony, suspicion by leaving behind trust and royalty and parental love as the children were sent out of their homes as early as three years to stand on their own legs and elderly peopled died due to absence of caretaking and love. Ik had the qualities of co-operation and control but later they never practiced theses qualities due to famine and hunger. Turnbull commented that he witnessed those vestiges of generosity, kindness and light-heartedness which disappeared by overnight by the occupation of survival instincts that cherish in all of us. [Turnbull 33]. Author had an occasion to live with this Ik population at the time of famine and political unrest in Uganda and witnessed the dying of older people and how Ik population was reduced to bare minimum due to these factors. He felt that Ik population was isolated due to famine from the society and finally the Ik population was completely vanished as it would be the fate of every marginal society. [p 285]. [Spencer 652] Turnbull narrated that Ik had no opportunity to have sumptuousness like sentiment, family and love. Since there was no societal affiliation, both the aged and children were regarded as futile. As long as if society keeps rearing group alive, one can always have more children. Since, in the absence of care, old perished first followed by Ik’s children population. Yet, there existed a ethnic suicide. [p 108 -109]. Further, due to continuous famine and drought, Ik perused basic survival tactics to live. [27]. The deterioration of social bindings does not connote that there is absence of collaboration between individuals. They assisted each other in times of help. [121]. Beating and harassing their wife is a pastime for Ik’s men. [138] . They also followed some rites in their marriage traditions. The bridegroom had to capture the bride in the cover of darkness though it was a prearranged one in advance. [106]. Though, the Ik’s had religious faith like worshipping ‘Didigwari’ name of a sky god in earlier days but later it was absent in the Ik’s society after the collapse of their society. [158]. Turnbull was of the opinion that Ik were enjoyed the best conservationists style of living as long as they were hunter / gatherer. [21]. Turnbull depiction of Ik style of living is almost analogues to Malthusian process where in the absence of epidemic and warfare, the population tends to increase to their ecological limit. However, in Ik model, the population completely vanished due to famine, hunger, neglect of older, younger and weaker dependants. Further, malice represents an unavoidable and sharp quality when some ecological shift revealed overpopulation for what it was. Turnbull is of the view that the effort to resettling down the Ik may have generated a distinct unprecedented turn in their ecology. Ik society won an interstitial position between adjoining karamojong-speaking pastoral tribes like trading, doing black-smith work, escorting them during their cattle raids resulted in intermigration and intermarriage with them. These individual ties namely [nyot] between Ik and pastoralists demonstrated that Ik were prepared to demonstrate longer term self-interest and a degree of trust which is absent elsewhere. [p. 162]. [Spencer 652] The Ik justify a place in the literature of reaction to stress and extreme deprivation. Children were actually taken care of in concentration sites. Besides a passing remark of Treblinka, Turnbull does not place them in this context and makes little comparison of any kind. [236]. Turnbull offered an interesting assumption that Ik’s hunter’s social group engaged in traits like amenability in social grouping and self-reliance and independence which acted as a kind of pre-adaptation for the dissolution of family tie in the light of continued catastrophe. [p. 287]. Turnbull is also of the view that there is still flourishment of artistic tradition among the Ik. [277]. Turnbull also elaborated that most of the Ik girls were disease-prone prostitutes and the young men desired to economize on their energy and wealth by engaging in masturbation and deserting the girls alone. [ 209]. Turnbull warns us as â€Å" this decline in human relationships among the Ik to the individual levels places the Ik one leap ahead of civilization†¦Our society has turning increasingly individualistic. Now, the family values tend to loose its significance and religious practice and belief bind us into communities of shared beliefs. The order in the society is being maintained existence of coercive power which is upholding a rigid law and by an equally harsh penal system. † [182]. In retaliation to a criticism to his book, Turnbull commented that the book has not written for anthropologists but it was fashioned to accomplish the anthropologist’s duty to reveal his findings to the general public. This book detailed â€Å"a varied numbers of anthropological issues and solutionss in such an thoughtless style that it merits both to hold up as a warning and to be sanctioned. † [Barth 100]. According to Henry A. Murray, a psychologist, the human behavior is ruled by a sequence of needs and when a fundamental need like food is unsatisfied, other higher order needs like trust, love must go by the board. This is true in case of Ik’s but Turnbull never aware of it. Turnbull findings was said to be deeply flawed both on ethnographical and ideological grounds. Turnbull love affair with the pygmies largely reflected his colored perception about the Ik. Turnbull acclaimed that the data covered in the book were insufficient for arriving an approaching proof. He frequently goes outside the limits of well accepted ethnographic reporting, interpreting his account with personal judgments and ascribing aims for observed behavior Turnbull is rather right in uttering that man is competent to unleash severe inhumanity to himself and Ik is certainly an extreme example of this. However, it is hilarious to note that Turnbull seems to visualize that he is the first to have discovered this fact and it is his duty to preach the world what he observed. According to Barkow, Collin Turnbull has given a superficial and exaggerated book. [Barkow 155]. The absence of bonding in the society was evident from the fact that when food was distributed by the Ugandan government to famine affected areas like Ik’s province, the younger generation went to the nearest town for collecting the food never cared to carry and supply them to the aged, weak people as they considered it as waste of food and time to feed their starving aged, weaker relatives and neighbors. [232]. Due to poverty, Ik deceived each other’s and Turnbull was not exception to this. Turnbull christened them as people without love and they were uncharitable, unfriendly, mean and inhospitable as any people can be. Turnbull compared the Ik society with that of inhuman conditions prevailed in Nazi death camps where Jews were butchered during the Second World War. Turnbull found the similarity of the extinction of Ik tribe without that of mass butchering of Jews in Nazi death camps and branded it on a global scale and forewarned that an ultimate destruction of mankind in near future. Turnbull in concluding chapter was of the opinion that Ik society had a bleak future. If unattended, their society would vanish in the course of time and it is very arduous to restructure their society. Government should help them to resettle by segregating them into smaller groups else they would miss their identity. However, Turnbull is fully aware that this action would be condemned by human rights organization but it is the need of the hour to preserve the Ik community in this vast universe.

Police Ethics and Deviance Essay

This paper intends to define ethics and briefly discuss its role in policing. It also aims to talk about the ethical standards in policing. Last but not least, it will also cover the deviant behaviors, as well as, its effects. Ethics Defined Ethics is technically defined as â€Å"the practical, normative study of the rightness and wrongness of human conduct† (Dempsey et. al., 2005, p. 292).   It is upon which conduct is based (Dempsey et. al., 2005, p. 292). It determines whether or not an act is morally correct (Dempsey et. al., 2005, p. 292). Nature of Ethics and Its Role in Policing Meanwhile, with regards to the nature of ethics being a standard of moral correctness, it contributes largely in policing (Dempsey et. al., 2005, p. 292).   Explaining further, without ethics, a police officer will not be able to carry out critical thinking; it is only through ethical decision-making that he will arrive with the best solutions to any issue he or she is faced with (Dempsey et. al., 2005, p. 292).   In addition to that, through ethics police officers tend to become honest and when they stay honest they are, as well as, their respected departments are respected which allow their team to â€Å"recognize their full potential† (Dempsey et. al., 2005, p. 292). See, ethics is really important to policing because it helps police officers do â€Å"good† and the carry out the â€Å"right acts† all the time (Dempsey et. al., 2005, p. 293). Ethical Standards in Policing In fact, to keep the police force doing good and the right thing, the department has come up with ethical standards in policing (Dempsey et. al., 2005, p. 293). These include the following: The first one is known as the â€Å"organizational value systems† (Dempsey et. al., 2005, p. 293). This has been produced so that police officers are taught the correct behaviors that they ought to instill in themselves (Dempsey et. al., 2005, p. 293). It serves as a guide as to what behaviors are correct and ethical (Dempsey et. al., 2005, p. 293). The second is technically referred to as the â€Å"oath of office† (Dempsey et. al., 2005, p. 293). This is like a promise made by the police officers that they will act according to the laws/rules/etcetera stipulated in the oath (Dempsey et. al., 2005, p. 293). The third is technically known as the â€Å"Law Enforcement Code of Ethics† (Dempsey et. al., 2005, p. 293). This one is disseminated by the â€Å"International Association of Chiefs of Police† (Dempsey et. al., 2005, p. 293). The last which the police force is obliged to follow also is the â€Å"US Constitution† (US Supreme Court, 2008, n.p.). Of course, the â€Å"Bill of Rights† go along with the aforementioned as well (Dempsey et. al., 2005, p. 293). Both are known to be the basis of police ethics because of its â€Å"lawful† character; lawful indeed, since it is a collection of the â€Å"US Supreme Court, Federal, State Criminal Laws, as well as, Codes of Criminal Procedure† (US Supreme Court, 2008, n.p.). Deviant Behaviors and Its Effects However, it cannot be denied that despite so many ethical standards utilized and implemented by the police force, there are still some who do not accept and follow it (Dempsey et. al., 2005, p. 293). Some of the deviant behaviors committed and its effects are the following: A) Police Corruption â€Å"Police corruption† is technically defined as â€Å"an act involving the misuse of authority by a police officer in a manner designed to produce personal gain for himself or others† (Dempsey et. al., 2005, p. 296). Examples of police corruption are the following: 1) receiving money from â€Å"loan sharks, hijackers, etc†; 2) receiving money, free food, free accommodations, etcetera in exchange for services rendered; 3) accepting money in exchange of classified information provided to â€Å"criminals or private investigation firms†; 4) accepting payment in exchange of not having parking and traffic violators summoned; 5) etcetera (Dempsey et. al., 2005, p. 295). As expected corruption brings about negative effects and these include the following: 1) it only motivates others to practice corruption also especially if police officers realize that there is a slight possibility of getting caught; 2) the police department is affected and the public’s respect for it is lost; and last but not least 3) people will no longer respect the police officers and will not follow the rules implemented by them eventually as well (Dempsey et. al., 2005, p. 300). B) Police Misconduct Police misconduct is also included in the list of deviant behaviors committed by some of the police officers (Dempsey et. al., 2005, p. 303). This entails: â€Å"the use of illegal drugs; alcohol abuse; abuse of authority; sexual violence; as well as, domestic violence† (Dempsey et. al., 2005, p. 303). The effect of this is just like in the first deviant behavior discussed wherein people tend to lose their trust on the police force and eventually carry out deviant behaviors as well (Dempsey et. al., 2005, p. 303). C) Police Brutality Police brutality is also one of the deviant behaviors committed by some of the police officers (Dempsey et. al., 2005, p. 308). This is defined as the unfair and extreme use of force on suspects and other criminals (Mangan, 2000, n.p.). The effects of such include: 1) psychological trauma for the victim; and 2) he or she will later turn out to be rebellious and revengeful (Dempsey et. al., 2005, p. 308).

The very definition of the term Alternative Despute Reselution is not easy, it can be through it indicate more than one way. This report is to Evaluate and learning from types of Alternative Dispute Resolution (ADR). And to look at services provided by the ACAS Introduction Working the concept ADR, it is unusual vision of the law shall not see through†¦show more content†¦Mediation is now carried on by lawyers, psychologists, social workers, the most sought precisely the intimacy they have with family problems.The mediator s job is to get the parties to dialogue with each other, and this dialogue will arise, of course, the solution to the impasse. Often the problem is not the separation itself, more in some act or fact, happened before, stored in the part of the unconscious, which is detected by the meter, certainly will bring the release, causing them to come back to at least to maintain the dialogue and thus have a normal relationship. Conciliation Conciliation is another method of non-adversarial resolution of conflicts, different from mediation, because it seeks immediate solution to a particular dispute. The conciliator in reconciling actively participates in the process suggesting, proposing, giving up solution to the dispute, it is accepted by the parties ends the dispute. In conciliation the conciliator is not tied to anything, he participates in an impartial manner, to steer the parties to make the demand. Conciliation is commonly used in judicial proceedings, both at
