Cellular Respiration and Fermentation - Essay Example nd aerobic respiration (Campebell 141).   Glycolysis produces two ATP and thirty-four more ATPs are produced by aerobic pathways if there is presence of oxygen. In absence of oxygen, fermentation reactions produce alcohol or lactic acid but not ATP (Campebell 142). During vigorous exercises more oxygen is consumed faster than required. More ATP energy is supplied to muscles by the process of glycolysis resulting in build up of lactate in muscles (Campbell Neil A. 304). When lactate builds up blood pH drops and the muscles are fatigued. When at rest lactate gets converted back to pyruvate and oxygen debt is repaid. This is the reason why a person continues to breathe hard even after finishing a race or rapidly climbing fleet of stairs (Campbell Neil A. 304). 3. Oxidative phosphorylation via the electron transport chain is carried out on the inner mitochondrial membrane (Strver 46). In absence of oxygen cellular respiration consists of only two metabolic pathways: glycolysis and fermentation both of which occurs in the cytosol (Strver 46). Glycolysis occurs in the cytosol (cytoplasm) and does not require oxygen. It is a process that includes a number of chemical reactions, each that require special enzymes to make it happen (Campbell Neil A. 147). During the third step of the process glucose gets converted to fructose. Fructose from organism’s food is put into the process and there are other ways to react chemically dietary sugars, lipids and proteins so that their energy can be recovered (Campbell Neil A. 146). All nutrients are used as fuel and act as building blocks. During the process glucose (C6) is broken down to two molecules of pyruvate (C3) (Strver 50).   This change is accompanied by a net gain of 2 ATP molecules and 2 nicotinamide adenine dinucleotide (NADH) molecules. There are ten steps in glycolysis and each is catalyzed by a specific enzyme (Strver 51). Two ATP molecules are then used to phosphorylate and activate some compounds that are

Muhamad Abdel Wahab Essay Example for Free

Muhamad Abdel Wahab Essay Mohammad Abdel Wahab was born in 1907 and died in May 3, 1991. He was a prominent 20th century Egyptian singer and composer born in Bab El Shriyah area of Cairo Egypt. He composed 10 songs for Omm Katherm, the greatest Arab songstress in history. Mohammad Abdel is a legend to the vast majority of Arabic speaking people. Mohammad was a renown singer, composer and actor and who lasted in musical career for spanning seventy four (74) years. He had a captivating voice and his melodies were of the classical poetry from the Arab’s golden age and that of their modern struggle against Western colonialism. Through this composition he instilled in his listener a feeling of pride in their Arabic’s rich culture and heritage. Though Abdul Wahab is known for his music, he composed more that he sang. Exploring the life of Abdul Wahab as a composer without referring to his songs or music and acting is inadequate for all of were a part of him and his many released songs and movies that later became `hits` were as a result of his creativity and talented mind. His enjoyed musical voice and the melodies were no doubt a product of his great composition. His songs were his own compositions and it is said that from his teens Mohammad had composed for himself and other leading Arab singers over 1800 romantic and patriotic songs (Salloum. Habeeb). His composition had the Western taste due to his innovative nature of always thinking of new and better ways to enrich the traditional songs. This is a factor that has contributed to a great extent to the popularity and influence of his compositions among the youth, a reason that has made his compositions to maintain the lead in music industry up to date. In the 1920s Mohammad is said to have become a close friend of a well known poet, Ahmad Shawky who helped him excel well in compositions and boost his talent as a composer. In the following years the world watched Muhammad Abdul Waham climb the ladder to later become a star and earned himself the title ‘singer of princes’ When the Egyptian monarchy was overthrown in 1952 by young nationalist army officers his perception of life changed drastically and radically. His songs which were purely his own compositions became more inspiring and more patriotic. He produced some of his finest works which included ‘The Eternal Nile’, ‘Damascus’, Palestine the musical scores for Egypt’s national anthem and the national anthems of Oman and the United Arab Republic. He composed political, national and Arab national songs; Muhammad also composed more songs after 1933. His compositions underwent different stages of development due to the environment in which he lived. Muhammad as a person accepted the changes and that is why his music in great deals synthesized the two worlds (both Western world and Arab world). (Levinson. M. L, 1995) His music was at first traditional a thing that later changed to westernization after he underwent formal training in both Arabic and Western music. Among his early composition of song was the Goose Consul Operetta, based on a theme of Naguib El Rehani which became a great success. Later his movie composition introduced female artist such as Leila Murad a thing that may have been found awkward during the time. Muhamad Abdul Wahab in his own way was a revolutionary leader in some sort of special way. His compositions featured large orchestras with a Western blend of instruments such as the guitar bass, accordion and later the organ and synthesizer. He also added new rhythmic formulas, including the tango, the mambo, samba and rumba, as well as the Arabic oriental rhythms, maqsoum and baladi in his compositions. (The story behind the stomp) In the 1960s Abdul Wahab composed songs for other singers such Om Koulthom. He released Omri a recording that later became Egypt’s all time best seller. In the 1970s he started fading from the public though his music from his own compositions continued with the same energy and vigor but in 1988 when he was (81), he emerged again to the surprise of many with new composition of his own. Age to him was nothing, infact it gave him more reason to write and consequently more reason to live. In his life time Abdul Wahab was recognized for his work in his great compositions, music and movie industries and hence received a lot of awards. Suprisingly enough his work is still rated as one of the best to have ever come from an Arab world. (Levinson. M. L) He died at the age of ninety and Egypt country honored him with a huge military funeral at the Rabia-al-Aldawiya Mosque in Cairo. After his death, his work was covered in newspapers, radio and television ranging from his compositions of songs and movies. He was accorded the title `The father of modern Arabic songs`. He died in 1991 of heart failure; he left a legacy nobody can afford to forget especially in the world of modern Arabic music and melody. Up to until his death Mohammad sorts peace in his writings, writings that appealed to both the old and the young. He stole many hearts with his music and compositions and became a beloved figure. Although he is gone he speaks to us through his work Works Ci

What Is Capacity Planning?

What Is Capacity Planning? Planning is concerned with thinking ahead, making provision. Capacity can be referred to as the upper limit on the rate of output. Another meaning of capacity can also be to maximum rate at which a transformation system produces or processes inputs. Therefore capacity planning can be defined as the process used to determine how much capacity is needed and when it is needed, in order to manufacture greater product or being production of a new product. According to TeamQuest (www.teamquest.ocm/capacityplanning Date access 12 Feb 2010) the goal of capacity plannings would be to provide satisfactory service levels to users in a cost-effective manner. Capacity planning has become a major issue in a global environment due to the financial benefits of the efficient use of capacity plans within material requirements planning systems and other information systems. Insufficient capacity will lead to insufficient delivery performance, stress on current work-in-process, and frustrate sales personnel and those in manufacturing. However, excess capacity can be costly and unnecessary. The lack of proper capacity planning will become a barrier to the achievement of maximising performance. With regard to Natref refinery they have a constant plan ahead for the next six months where the last three months are fixed. A shortage of supply would definitely influence its ability to provide according to its estimates. The supplies need to be monitored closely due to the fact that capacity is a possible restraint, especially when there is a need for stock building. These problems are closely planned and scheduled to reduce unforeseen capacity problems. The planning is done by the shareholders of Natref namely Sasol, that holds 63.64% of the shares and Total that holds 36.36% shares. The shareholders are very closely involved with Natrefs daily operations. The levels of capacity and production rate is constantly monitored to ensure that the plant is run in an optimized way and to ensure that there are no shortage of raw materials. When doing capacity planning it is important to consider the following three steps as set out by TeamQuest (www.teamquest.ocm/capacityplanning Date access 12 Feb 2010): To follow the above mentioned steps, you can ensure that your organisation will be prepared for the future. You will have the information necessary to purchase only what you need, avoiding over-provisioning while at the same time assuring adequate service. To be able to do capacity planning it is important to understand and determine the market requirements. To be able to determine the requirements you need to understand the workloads. Before setting service/product levels, you need to determine what unit you will use to measure the incoming work. According to TeamQuest (www.teamquest.ocm/capacityplanning Date access 12 Feb 2010) the workload can be explained as a logical classification of work performed. It is useful to analyze the work done on systems in terms that make sense BOTTLENECKS What is a bottleneck? A Bottleneck is the action that occurs and causes the capacity in a certain procedure that is not fully utilized for (Operations Supply Management, Jacobs, Chase, Aquilano, 2009:165) this action, it may be time, how long it takes to complete the task or the facilities that are in process for instance dispatch places of the final product. Business Definition: Bottleneck (http://dictionary.bnet.com/definition/bottleneck.html Date of access 10 Feb 2010) An activity within an organization which has a lower capacity than preceding or subsequent activities, thereby limiting throughput. Bottlenecks are often the cause of a build-up of work in progress and of idle time, A limiting factor on the rate of an operation. A workstation operating at its maximum capacity becomes a bottleneck if the rate of production elsewhere in the plant increases throughput but at that workstation can not be increased to meet demand. An understanding of bottlenecks is important if the efficiency and capacity of an assembly line are to be increased. The techniques of fishbone charts, Pareto charts, and flow charts can be used to identify where and why bottlenecks occur. Identification of bottlenecks (Production and Operations Management, Ray Wild, 1979) There are two ways to identify bottlenecks in a system, first check whether the resource profile is correct for the given capacity and secondly make use of the knowledge of personnel in the specific layout by discussing this and finding out where they see the bottlenecks. In the process to avert and manage bottlenecks, there need to be looked at the following factors: The work that must be done and the work ethics The goal is to establish what the most economic way is, to get the work done. To standardize the method, equipment and material that is used to get the work done. Furthermore there should be established how much time a qualified worker needs to do a job of a given quality standard. It is important that this process be applied for maximum benefit to the organization. The interpretation of the layout Points that need to be looked at are the following: Cost of the handling and moving of crude oil. Utilization of labour, facilities and the space of the plant. Are there initial plans for the maximization or minimization of the layout? If equipment needs to be changed or replaced, does the plant compensate for it? Capacity planning and management thereof Effective capacity management is of utmost importance to Natref. The main goal for capacity planning is to balance the level of manufacturing to the demand of the product being manufactured. Capacity planning comes down to the following two factors: Determining the capacity needed for the manufacturing system. By developing and implementing a strategy that can be used in the existing process by applying resources in such a manner those fluctuations can supply in demand. Scheduling Because Natref is operating on a LEAN process, scheduling is of utmost importance, for example when a shutdown is planned. This means that certain activities will have to be rescheduled, for example, more completed products will have to be stored for the demand thereof during the shutdown. The ships with crude oil that have been ordered, will have to be rescheduled, because there might not be storage available at Natcos. The design and scheduling of the process flow See if the refinery process used by Natref is entailing optimal flow, in other words, is the manufacturing line in balance. All these processes are being used and implemented by Natref. What makes the situation at Natref a slightly different is that bottlenecks can not only arise in the layout, but also in the process of crude oil being provided from Durban by pipe line. Bottlenecks can also arise at the storage facility (Natcos). Refer to Annexure A for the schematic presentation on the potential bottlenecks. All the points marked A, B, C, D and E can be identified as probable bottlenecks. Because Natref itself does not have a lot of storage capacity (LEAN) for crude oil, they should act more pro-active to avoid bottlenecks in the refining and procurement stages. If bottlenecks occur during the refining process, then it should be dealt with the utmost urgency. Note to Natref At present Natrefs biggest points for bottlenecks are the procuring and shipping of ready products, because in both cases they do not have enough storage capacity. The existing shipping facility is too small and therefore a bigger shipping facility is being built to increase the tempo for road- and rail transport. This is a much cheaper option to building a storage facility at Natref, because there would be less risk due to fire hazards when product is kept in storage. Natrefs main goal is procurement of energy resources. Natref should in fact make use of its clients storage facilities and so shipping its ready-made products quicker. Relating to the procurement of crude oil, Natref should manage bottlenecks as follows for minimum risks: Advanced buying of crude oil should be scheduled that there would always be enough ships on its way, so that Natcos (storage farm at Durban) would not run out and that there would always be enough storage space. Maintenance plans for the pipe line from Natcos to Natref should be thoroughly seen through, so that continual flow of crude oil can be maintained. Maintenance should be synchronized during shutdown dates. CAPACITY PLANNING: CHANGES IN DEMAND AND SUPPLY The business environment has never been more challenging than it is right now. The speed of change in the marketplace is creating a stress on corporations to respond quickly and effectively. The foundation that is required to react to dynamic changes in supply and demand is based on understanding your supply chains capacities. Understanding and then building the infrastructure that provides the needed flexibility and speed requires an in-depth understanding of how capacity impacts your business. The impact of capacity management is felt throughout the organization, within every element of the supply chain. Supplier capacity can bring production to a standstill. Production capacity is equally important; if the capacity is not great enough to meet peak demand periods and inventory building is not properly planned, customer demand will go unfilled. Distribution capacity, both storage and throughput, ensures delivery of the right product at the right time. Transportation connects all elements of the supply chain; as such, its capacity issues are key, influencing service levels and on-time delivery performance. Change has become the rule, not the exception. The need for capacity management is measured not in years or quarters but rather in weeks and months. Changes can be brutally fast and without warning. Industry over the past two years has been hit hard with a steep slowdown of their business. Some were managing their capacity to great detail during the late 90s, with state of the art systems in place; however, these systems failed when business conditions began impacting their extended supply chains, including contract manufacturers and suppliers. With these current levels of change, dynamic measurement and planning tools have become a necessity. External as well as internal dynamics create the need for constant monitoring and adjustment of capacity levels and policies. Global economic conditions and competitors cause external pressures that challenge current business practices. From price pressures to raw material availability, organizations must be flexible enough to react quickly to these changes. Internal dynamics can be equally as disruptive. Acquisitions and partnerships as well as moves into new markets create opportunities to leverage current assets and spend capital wisely. However, without proper planning, these opportunities can become large challenges and liabilities if synergies are not exploited. No matter how well capacity planning is conducted, these decisions must periodically be revisited to make sure they are still aligned with the organizations goals. If so, they will provide the foundation to support new initiatives including collaboration throughout the extended supply chain. Management Reality: A subjective issue As every manager knows, capacity is a difficult concept to quantify. Whether its a workstations ability to process jobs or a manufacturing plants capability for a year, the answer is frequently it depends. Because of the dynamic nature of capacity and the interrelationships among different supply chain elements, capacity is forever changing. Product-mix changes, process or equipment engineering improvements, labor availability and new data management systems are only a few reasons capacity can suddenly change. The most available and, therefore, most popular measure of capacity is the past-but the past is not necessarily a good indication of the future. There is an answer. Many tools have been developed to address the dynamic nature of supply chains today. In an effort to empower managers, to allow them to plan rather than react, planning tools evaluate a variety of variables and are superior to educated guessing about where, how much and when capacity should be modified. With a scope ranging from a full view of the supply chain to a subset of the organization to a micro within the box view of a facility, there is a tool to meet any capacity management need. These tools help quantify the differences among alternatives and lead to a greater understanding of the interrelationships within a supply chain. From identifying bottlenecks, to backup suppliers, to available alternate routings, to contingency planning, the true cost and impact of decisions can be evaluated. Because all elements of the system being studied can be represented at once, sub-optimization can be avoided. Alternatives can be objectively evaluated to determine their t rue impact on a variety of performance measures, including throughput capacity, inventory levels, and cycle times, before expensive and disruptive changes are made. According to Baltzan et al. (2009:184) demand planning SCM (Supply Chain Management) software can help an organization determine capacity. An organization must determine the performance capacity level for each of its facilities. If it decides a facility will have a large amount of excess capacity, which provides the flexibility to respond to wide swings in demand, then it is choosing an effectiveness strategy. Excess capacity, however, cost money and can therefore decrease efficiency. Natref does just this, by utilising its software, swinging the throughput of its product albeit Diesel or Petrol, whenever the demand for the one product exceeds that of the other the system can rapidly change the throughput of the product needed. Competitive Advantage: Knowledge is Power Capacitys pervasive influence and the pace of change make the need for accurate knowledge and flexibility a necessity. The ability to quickly react, while making educated and informed decisions, will directly impact the health and success of your organization. It will enable you to rise above your competition, to compete based on your supply chain and the service and flexibility you can provide. In todays dynamic business environment, speed and flexibility are a necessity. From being able to quickly respond to business conditions to reacting to dramatic changes in customer demand, a disproportion of capacity can have devastating results. Too much capacity can result in low return on assets, morale damaging layoffs and expensive facility closures while too little can result in lost sales and eroding customer loyalty. Utilizing a strategic network design tool allows an organization to objectively evaluate its extended supply chain and simultaneously consider all costs and business policies. This understanding can then drive an organizations capital expenditures and strategies as they build a world-class supply chain, built to compete against any organization in the world. It can be said that from the information provided by Natref it is utilising its capacity very successful. In total Natref produces 170 000 m3 of Petrol 170 000m3 of Diesel fuel + 30 000 m3 of Diesel fuel for export markets, 110 000 m3 of Jet-Fuel (kerosene) and 25 000 t Heavy Fuel Oil for industrial use 13 000 t of Bitumen. Thus a total of 480 000m3 and 38 000t of product. The demand fluctuates constantly and Natref has to constantly stay abreast with changes. Natref are fortunate to have shareholders that have a direct input into the market that helps with its planning. TECHNIQUES TO DETERMINE LONG-TERM CAPACITY REQUIREMENTS To achieve real (effective) capacity, you must understand what is produce, need to look at both resource input and product output. As operation manager you have to ensure to view also the dimension of capacity, and that capacity must be stated relative to some period of time. This is evidence in the common distinction draw between long-range, intermediate-range, and short-range capacity planning.(Jacobs, Chase and Aquilano (2009:121-122)) According to Jacobs et al (2009:123-124) the objective of strategic capacity planning is to provide an approach for determining the overall capacity level of capital-intensive resources facilities, equipment, and overall labour force size that best support the companys long-range competitive strategy. To ensure overall capacity level the concept of best operating level must be used and at all time ensure a 100% capacity utilization rate is acquired. Capacity utilization rate is determined by the actual capacity used divided by the actual capacity it has been developing for. The % out of 100 will determined the utilization rate. When determining capacity requirements, you have to require demand for each product line, individual plant capabilities, and allocation from production: Use forecasting techniques to predict sales for individual products within each product line. Calculate equipment and labour requirements to meet product line forecasting. Project labour and equipment available over the planning horizon. (Jacobs et al (2009:121-122)) To evaluate capacity alternatives Jacobs et al (2009:131) suggests the use of a decision tree. A decision tree is a convenient way to evaluate a capacity investment decision; this does not only help to understand the problem but also finds a solution. A decision tree is a schematic model of the sequence of steps in a problem and the conditions and consequences of each step. The way forward is that a square indicates a decision point and the circles represent change events. Branches from decision point show choices available for decision maker, branches from chance events show the probabilities for occurrence. To solve the tree you work back from the end to the start of the tree, you calculate the expected values of each step, by calculating the value of each step the time and money value is important if the planning horizon is long. Example diagram of a decision tree Once the calculation is made you prune the tree by eliminating from each decision point all the branches except the one with the highest pay off. This continues until the first decision point and problems are solved. If no changes are made competitors will move in and would make expansion no longer feasible. According to an International Journal of Production Economics (2001:p215-22) in a manufacturing strategy, capacity is a structural decision category, dealing with dynamic capacity expansion and reduction relative to the long-term changes in demand levels. Sales and operation planning (SOP) is the long-term planning of production levels relative to sales within the frame work of a manufacturing planning and control system. Within the SOP, resources planning are used for determining the appropriate capacity levels in order to support the production plan. Manufacturing strategy and sales operation planning provides two perspectives on long-term capacity management, raising and treating different issues. Note to Natref: regarding best practice techniques to determine long-term capacity requirements Natref needs to: Estimate the capacity of the present facilities 115 000 barrels/day All petrol grades @ 3500 liter/minute 80% of JIA jet fuel requirements @ 2000 l/minute, and Diesel @ 4500 liters/minute With above information Natref need to establish their capacity utilization percentage and relates the actual output to output capacity and actual input use to input capacity. This will determine the efficiency of the current input and output capacity. With this a capacity cushion need to be added on to the capacity demand to allow for: greater than expected demand, demand during peak demand seasons, lower production cost, product and volume flexibility and improve quality of products and services. Forecast the long-range future capacity needs Natref need to consider the life input for the next 5 years and understand the product life cycle as it impacts capacity. Anticipate technology development and competitors action. Forecast the strategy and demand of shareholders. Ask the question what will change to the current month productions in 5 years: 170 000 m3 of Petrol 30 000 m3 of Diesel fuel for export markets 110 000 m3 Jet-fuel 25 000 t heavy fuel oil for industrial use Natref could also expand long-term capacity by: Subcontract with other companies, acquire other companies facilities and resources Expand , update or modify excising facilities When all above is done and the forecast and capacity requirements has been establish. Two approaches could be followed namely expand all at once or expand incrementally. Expand all at once build the ultimate facility now and grow into it Little risk of having to turn down business due to inadequate capacity and less interruption of production One large project cost less than few smaller projects and due to inflation, will construction cost be higher in the future Incrementally build as capacity demand grow Less risky if forecast needs to materialize and funds are not teid up in capacity for other investment possibilities Appropriate for new products May suggestion would be that after Natref has decides what strategy they want to take for the next 5 years regarding long-term capacity requirements they need to analyze more than one suggestion in a decision tree the expected value approach. The decision point would be the 5 year strategy, regarding this Natref need to determine more than one change event that will have an expected value. This will allow Natref to see all choices available for decision making and the probabilities for occurrence. When all the choices available value are calculated, Natref need to work back from the end of the tree to the start of the tree, this will allow Natref to calculated the expected value of each step and the time and money to determine the actual long-term requirements for the next 5 years. WAYS TO COUNTER LACK OF CAPACITY DURING PEAK DEMANDS/SHUTDOWNS If the goal of capacity planning is to provide satisfactory service levels to users in a cost effective manner, then the lack of capacity would be not succeeding in providing satisfactory service levels. And if capacity planning is defined as the process that is used to determine how much capacity is needed and when it is needed, in order to manufacture greater products or production of a new product, then lack of capacity is the situation where a goal is not achieved, due to some or other constraint in the process. According to a study conducted by Sylvester, Lendon and Bevan (2004:1) they prove that to continually add capacity is not a viable solution to counter the lack of capacity. In their study they needed to properly understand and manage patient flow in a hospital. This is removed from the capacity at a refinery, but the basics would still be the same. If one compare this directly to the Natref state of affairs, the assumption would be that to add capacity would not necessarily counter the lack of capacity. Natref is currently in the process of establishing another storage facility. The cost of adding this facility is very high, approximately R300 million. It is therefore not possible to constantly add capacity or storage facilities every time it seems that a lack of capacity will occur. Natref counter a lack of capacity by erecting a new storage facility, by ensuring that their estimates and planning for the given shutdown/peak period is precise. Although the product is stored periodically, to ensure that on the date of the shutdown or when the peak demand starts, it has sufficient stock to continue with the demand or supply in the additional situation, Natref should investigate the possibilities of utilising external sources of capacity. These storage facilities could include the underground tanks of the individual filling stations, and/or determining the product that will most likely be short or that needs to be stored for future use and to expand the storage of that product and less ening the storage of the product that would not be used as frequently. According to TeamQuest (www.teamquest.ocm/capacityplanning Date access 12 Feb 2010): there are five noteworthy reasons why capacity planning fails. It would also be possible to trace these reasons back and make a connection with the lack of capacity. If the planning fails the capacity would most probably fail as well. These five reasons are: 1. Imperfect data; 2. Lack of common goals; 3. Trendy versus modelling; 4. Too narrow view; 5. Flaws in the prediction method. If these five facts are taken into consideration when the capacity planning is done, it would increase the possibility of success for a project. Further there are three important considerations taken into account when adding capacity. They are: 1. Maintaining system balance; 2. Frequency of capacity; and 3. Use of external capacity. When analysing current capacity there are four basic steps that could be used to assist you: TeamQuest (www.teamquest.ocm/capacityplanning Date access 12 Feb 2010) identifies the following four steps: The first step would include comparing the measurements of any items referenced in the service level agreements with their objectives. This will indicate whether the system has adequate capacity. The second step would include checking the usage of resources. This analysis identifies highly used resources that may prove problematic at present or in the future. The third step would include looking at the resource utilisation for each workload. Determine which workloads are the major users of each resource. This will indicate the workloads that are making the greatest demands on the system resources. The fourth step is to determine where each workload is spending its time by analysing the components of response time. Allowing you to determine which system resources are responsible for the greatest portion of the response time for each workload. When measuring capacity you need to consider the following: Design capacity: the maximum output that can possibly be attained. Effective capacity: The maximum possible output given a product mix, scheduling difficulties, machine maintenance, quality factors, and so on. Actual output: the rate of output actually achieved. Measuring of System Effectiveness: Efficiency: the ratio of actual output to effective capacity Utilization the ratio of actual output to design capacity. PLAN FOR THE FUTURE: To ensure that you will be able to meet the requirements of the market in a years time, you need to do capacity planning based on the forecasted processing requirements. You need to know the expected amount of incoming work, by workload. That will allow you to calculate the optimal system configuration for satisfying service levels. Future processing requirements can come from a variety of sources. Input form management may include: Expected growth in the business Requirements for implementing new applications Planned acquisitions or divestitures to name but a few. Additional, future processing requirements may be identified from trends in historical measurements of incoming work such as orders or transactions. After system capacity requirements for the future are identified, a capacity plan should be developed to prepare for it. The first step in doing this is to create a model of the current configuration. From this starting point, the model can be modified to reflect the future capacity requirements. If the results of the model indicate that the current configuration does not provide sufficient capacity for the future requirements, then the model can be used to evaluate configuration alternatives to find the optimal way to provide sufficient capacity. When considering capacity planning there are even more issues to consider. Best practices. Since the late nineties refineries have expanded capacity significantly, production capacity has increased tremendously. As refineries got larger, it was expected that emissions would increase as well. Environmental problems have become a huge issue due to the large expansion in demand for product. Goals to achieve the environmental standards and best practices are a large part of capacity planning and production. Finding newer and better ways of producing more product and faster and cheaper. New modern techniques have challenged organisations to rethink the way they conduct business both internally and externally. To determine how efficiently and effectively their entire supply chain is managed. The petroleum refining industry has effectively embraced the software solutions to optimise the business supply chain to maximise the profit margins and create order in the chaos of numerous opportunities and challenges. The supply chain of a typical petroleum refining company involves a wide spectrum of activities, starting form crude purchase and crude transportation to refineries, refining operations, product transportation and finally delivering the product to the end user. The nature of the value chain is such that its economics are extremely complex and heavily linked. For example the process of selecting the right crude is liked not only to the transportation costs involved in delivering to the refinery, but it must take into consideration the refinery configuration, capabilities and constraints in converting the crude into products, as well as the product volume and price fluctuations. Software solutions based on Linear programming (LP) technique have emerged as leaders among various mathematical optimization techniques available to optimize the entire supply chain form crude evaluation and selection, production planning and product logistic planning Refinery planning form the foundation for the business decisions that have the biggest impact on refinery profitability. The following are plans that should be considered: Annual plans Monthly rolling plans Weekly Plans Strategic Plans Profitability improvement plans LONG TERM CAPACITY PLANNING According to the Encyclopaedia of Business, 2nd ed. The following is explained under long term capacity planning: Over the long term, capacity planning relates primarily to strategic issues. This involves the firms major production facilities. This type of planning also involves location decisions, technology and transferability of the process to other products. Long term capacity planning may evolve when short term changes in capacity are insufficient. Long term considerations relates to overall level of capacity Det

Otto Boudet Ms. Ramirez British Literature 1600 4 December 2013 The Mind of Thomas Nashe: An Enigma Thomas Nashe is thought to be one of the world’s first picaresque writers. Although he is a picaresque writer, critics have a hard time characterizing his works due to his incoherent literary structure. Thomas Nashe has been pinned as an enigma of the literary community as his writing often portrays multiple writing styles all at once. â€Å"The Unfortunate Traveller† is the epitome of this. It is categorized as a picaresque novel, but it is a gruesome and violent story. The story is almost a paradox itself. Thomas Nashe, born in 1567, lived in the small town of Lowestroft, Suffolk. Not much is known of his early life, other than that his father was a curate and that he was baptized at his father’s church. He went on to study at the University of St. Johns at Cambridge where he acquired his bachelors degree. Little is known on whether his time at college influenced his works. After his time at college he moved to London, where he was hired by the ecclesiastical authorities to write pamphlets and essays in an attempt to discredit a man know as â€Å"Martin Marprelate† (Kinney Page 1). This alias was used by a man who was writing colloquial speeches regarding the episcopacy of the Anglican Church. Nashe might have not been one of the main contributors to the counterattack against â€Å"Martin Marprelate,† but he was able to extract a sort of writing style from the experience. After his excursion with the Anglican Church, his writing became more spontaneous and unstudied (Donno Page 1). This spontaneous and unstudied style was more prominent in his early works such as â€Å"The Anatomie of Unsertantie" and the preface of Robert Greene’s â€Å"Menapho... ...e Unfortunate Traveller.† What angered the writers the most, was the accuracy of what Thomas Nashe was saying, even if it was in a sarcastic tone. Not only did he anger authors, poets, and pamphleteers, but he also angered the British government. Although his jeers were not directed towards the government, Nashe’s use of the atrocities throughout the country was thoroughly disliked. The government believed that his rendition of the gross actions of England’s people would tarnish its reputation. Thomas Nashe is coined with being one of the world’s first picaresque writers. It is quite ironic how after centuries of debate concerning his eloquent pamphlets and gruesome narratives that he is now categorized under a satirical genre. Although he did incorporate this satire and sarcasm in many of works, it seems unjust to confine him to the one genre.

A Latin Christmas Essay

In Martin Espada’s â€Å"Latin Night at the Pawnshop,† the poet examines the Latin culture during Christmas time in a young, but still growing community of Latino immigrants. The poem proposes that during some time in America, people of Latino descent could not enjoy themselves during the holidays as they would if they were in their own country. Therefore, the theme of the poem is heavily influenced by the demise of Latin culture in America. Espada augments his poem to make the theme clear by using the following elements of poetry: diction and tone, symbols, and imagery. Diction and tone play a critical role in Espada’s poem. In the first line, Espada uses what I think to be the most important word in the whole poem, â€Å"apparition†, to bring about a vision he has of a salsa band through the window of a pawnshop. The word apparition means a ghostlike image. By evaluating this word and its context, the poem itself has created a tone right away. We can say that the mood of this poem is very gloomy and depressing when all one can see is a ghost and nothing else. The poem then continues with descriptive words to describe other aspects. For instance, the word â€Å"gleaming† is introduced. The word gleaming means to shine brightly. By introducing this word, the poet draws emphasis on how important this salsa band is to him during Christmas. However, locked in the shop are â€Å"gleaming† instruments that can’t play no more and Christmas to him is left in utter silence. Moreover, Espada mentions two distinct colors, a â€Å"golden trumpet† (line 4) and a â€Å"silver trombone† (line 5). Both silver and gold help represent the time of Christmas. Almost all Christmas trees use silver and gold ornaments as a decorative feature. Also, the poem ends with another word worth noting, â€Å"morgue†. A morgue is a place where dead bodies are kept. Ironically, during Christmas, we don’t associate death with such a joyful time. However, in this poem, a connotation for the word morgue could include death. Now, putting all these elements together, we can conclude that Espada is revealing a very dark Christmas he had gone through. A Christmas where there was no trumpet blowing, no trombone playing, no congas drumming, no maracas swinging, no tambourines shaking, and that all present was just the thought of it-no real Christmas. Espada also uses symbols to further develop his point. The three major symbols in this poem are indeed the pawnshop, the instruments, and the price tags. First, the essence of the pawnshop itself is important because it tells a story, beyond itself. Sometimes money gets in the way of a person’s happiness. As a result, we pawn the stuff we really cherish for a quick buck. Espada is trying to explain that on top of the struggles Latinos face, they also must sacrifice the things they love. Second, the instruments tell us a great deal about the demise of Latin culture in America. Instead of being played and making great music during the holidays, they sit there unused. Espada in his poem creates an unwanted feeling. Lastly, the price tags that resemble that of a dead man’s toe are equally important. The tickets symbolize the presence of death where there should be life. The Latin culture in the town of Chelsea is completely dead. Latinos have given up on their culture in place where it’s not truly accepted. These elements create the point Espada is trying to express. Imagery is also an important aspect to this poem. The poet creates imagery that attacks several senses and by doing so, it also helps pinpoint the importance of different ideas. Espada writes, â€Å"gleaming in the Liberty loan pawnshop window,† (line 2). As one reads, you can’t help but imagine seeing this bright light coming out through a window and showing you a salsa band. Furthermore, Espada mentions several instruments. With this inclusion, one can imagine hearing the sounds of these lovely instruments playing coherently and in sync together. However, Espada also writes, â€Å"all the price tags dangling like the city morgue ticket on a dead man’s toe,† (lines 7,8,9). This image develops a kind of chilly and nervous feeling about what’s actually going on in the poem. All in all, by putting these sources of imagery together, you notice what the poet is trying convey. Espada is drawing our attention to a salsa band and all of its instruments, but in the end things aren’t always what we want or expect. The Latino culture is nothing more than an illusion, in a land that does not treat its immigrants well. Thus, in â€Å"Latin Night at the Pawnshop,† Espada creates a poem that expresses  his concerns about Latin culture in Massachusetts in the late 1980’s by using different elements of poetry. The power of diction and tone, symbols, and imagery, enrich the central theme the poet wants to make. Espada does a great job converting one simple moment, into a thousand words and ideas.

Consent to medical treatment medical law Essay

Consent to medical treatment, medical law Introduction   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Medical treatment and law are interrelated, the relationship between the two resulted to medical law which is of greater help for millions of people in the whole world. Medical law varies in different countries. They all serve the same purpose of protecting the interest of patients during the time of medication process. Medical law covers different areas of medication and it contains different sub-laws that define different areas of medication. The issue of consent is one of the critical issues that are addressed by this medical law. This is because there have been many cases where patients have been subjected to medical treatment without their will. Medical law gives patients the right to make decisions of their will without any influence but under certain conditions like capacity of the patient to make decisions. The torts of negligence and battery are also common issues that are addressed under medical law. The two torts register the hi ghest number of cases in courts because they are commonly violated by the medical practitioners. The objective of the paper is to critically analyze the concept of consent, tort of battery and tort of negligence. The analysis will be supported by different case laws under each concept.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Consent is a situation where a patient is given the right to decides what should be done to his or her body. If a medical practitioner touches the patient without this concept, the act is referred to be unlawful. A medical practitioner is said to act lawfully when touching a patient under the following circumstances, but it is good to note that each circumstance depends on the category of the patient. The major categories of patients are; adults who are competence, adults who are incompetence, young people of below 16 years old and patients who require urgent care. For the case of competence adults the medical practitioner must get the concept of the patient before subjecting him or her to medical treatment. The consent should be from the person but not any person because the law views a competence adult as a person who can make right decisions. If the physician touches the patient without his or her concept, the act is completely unlawful .   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In the category of incompetent adult, the medical law defines that the person cannot make right wise decision and thus the physician should not comply with the person’s consent. However, this does not mean that the physician has the right to subject the person to medication. The physician should get the concept of the court of law or close family member of the person and in this case, the physician can touch the person lawfully. The category of Children of below 16 years old can be well explained using the Gillick vs. West Norfolk health facility. In this particular case, the West Norfolk was changed in the court of law because of subjecting girls of below 16 years old to contraceptive treatment without the concept of their parents. This indicates that a medical practitioner should not touch a child of below 16 years without parental or legal consent and thus it is lawful for a medical practitioner to touch a child under the consent of parents. In the category of emergence cases where urgent treatment is required, the physician should first use all the means possible in order to get the patients consent. However, the physician can subject medication to a patient without consent and it becomes lawful under the following situations which are highlighted in the medical law act. If the patient is disabled in search a way that he or she cannot be able to communicate, if there is a language barrier between the patient and the medical practitioner, if the delay would cause dangerous complications to the patient, if all possible ways of getting the patients consent has been exhausted and if there is a good reason that the patient cannot refuse the treatment. The above reasons give the physician the right to touch a patient lawfully.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   There many instances where the medical practitioner acts against the consent of the patient. The medical practitioner commits a tort of negligence. This is a very dangerous tort because it has left many people dead and others disabled, it is mostly caused by lack of proper concentration and seriousness of physicians in their medical operations. There are many cases where the physicians have been sued because of acting against or without the consent of the patient. A good example is the Alexander Baez vs. Sylvester. Alexander was a body builder and he decided to go to a medical practitioner for Pec implants the doctor by operated him implanted him with breast implants instead of pec implants. This is just a representation of millions of cases that involves tort of negligence.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The issue of consent is very critical; this is because the medical practitioner is usually reliable for touching a patient without consent and also treating a patient with consent which is not well informed. The main issues lies on to what extent should the medical practitioner advice the patient when coming up with the consent. Two cases can be of greater help in the process of analyzing this issue.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The first case is the case between Sidaway vs. Bethlem. Sidaway was a patient where she had gone for a surgery in order to remove a trapped nerve. Bethlem was the one who handled the patient. After surgery, the patient paralyzed and he sued the doctor because of negligence. He claimed that the doctor had not disclosed the negative effects of the surgery and thus it was a form of negligence.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The second case is between Chester vs. Afsher. Where Chester was a journalist and she had a problem of back pain and one of her medical practitioner advised her for a surgery. Chester decided to visit Afsher as a private patient and she requested for a spinal surgery. The surgery caused nerves damage and she became paralyzed. As a result of that, she sued the doctor for negligence because she claimed that the doctor had not disclosed all the information about the negative of the surgery.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The two cases were addressed in different ways though they look the same, the judge in the Sidaway case sided with the doctor’s side while in the majority in the Chester case sided with the patient side. The two cases were under the English law that states that the patient must be provided with all information whether positive or negative about the medical operation for the purpose of making balanced decision. In both cases, the patients complained that they had not been well informed about the possible consequences. The first case judgment was against the English law because the doctor had not provided with all the information. In the second case, I strongly agree with the majority in that case who supported Chester. This is because failure to provide the necessary information to the patient is a form of negligence and thus the doctor went against the law.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Self-determination of patients influences the consent making process in a greater way. In the Sidaway case, lord Scarman endorsed therapeutic privileges. This has massive effects to the patients because it raises the self-determination of the patient. If patient’s self-determination is triggered there is a possibility that the patient would make decisions out of excitement. This has resulted to a lot of cases of negligence which are indeed out of patient’s high hopes in making their consents. That is the reason why the medical practitioners should provide the both sides of information in order to give the patient a chance to make balanced decision which are not out of excitement or any influence. This would reduce many cases of negligence which affects both parties depending on the jury addressing the issue. There is no danger of informing the patient about all the information concerning the operation regardless of how simple it is because it is not easy to know the information that will have an impact in the decision making process of the patient.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Operation to correct sticking years is an operation that is carried out by medical practitioners in for prestige because stick ears have no health complications. Many parents prefer to take their children’s for this operation while they are still young. However, anything that might happen to the child during the operation is justified and the medical practitioner cannot be responsible of anything.This is because the consent of parent is enough to legalize the child operation. However, there are some circumstances that can prevent this justification. The medical operator should provide all the necessary information about the operation and failure to do so can result to lack of justification. Beauchamp vs. Childress case is a good explanation for this point because the case addressed the issue where Childress organization sued parents and physician who operated a child and the child developed problems. The jury ruled in favor of paren ts and physicians because the stick year operation was done in consent of parents.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The issue of circumcision is related to the above case but it takes different angles, this is because there is child circumcision and adult circumcision. In the case of child circumcision, the consent must be from the parent and they have the legal right to make the decision. In this case, the circumcision process is justified and thus the doctor has no blame if there is proper application of skills.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The situation can be unjustified if the medical operator shows any kind of unprofessionalism or if the child experiences complications which are as a result of physician’s era. There is a difference between the law of circumcision in males and females. The male law on circumcision is not well established because male circumcision is viewed as a normal process. The male law of circumcision states that parents of a child have the right to circumcise their male child or not. It is good to note that this law does not tackle the issue of circumcision based on cultural or religious believes. When it comes to female circumcision, the law does not support it in any way. It is illegal to operate a female whether in her consent or in the consent of another person. The law prohibits parents form influencing their children for circumcision in any way. The law also prohibits the gentle mutilation whether with the consent of the child or with the consent of the parent. The law further elaborates this issue the tort of battery, the law explains that a medical practitioner should not in any case use any means to persuade a female for genital mutilation. Male circumcision should not be made illegal because it is performed under the consent of parents and also it does not have dangerous complications. Mental capacity Act 2005 section one two contains detailed guidelines on how best interest of a person who lack capacity should be determined. When a person has no capacity to make decision, the best interest of the person is determined. A person can be disabled in a way he or she cannot be in a position of making any decision or there can be a language barrier between the patient and the physician and that is where the concept of best interest is applied.That Act states that the best interest of the person should not be determined according to the age or physical appearance of the person. Best interest of incapacitated patient sh ould be determined by, consultation of any person who is to the patient, any personal interest that might have been written or said by the patient when he or she was in full capacity and the decision of the attorney. The Act further elaborates that all process that should make the patient to give the consent should be exhausted before deciding the best interest of the person. Lastly, the beliefs if any of the person should be used to determine the best interest of the person because the act argues that the beliefs influence the decision of a person in a greater way.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Least restrictive alternative principle mean is applied when determining the best interest for an incapacitated patient. The principle states that when applying the best interest, the less intrusive option should be considered. This means that some options that are suggested as best interest are not the same, there are some which are more convenient to the person and they should be given the first priority. In case of unconscious person in a surgery table and the doctors operating the person notices that they would have an additional operation that they had not explained to me, the following is the best suggested for them that they can proceed with. Since the person is unconscious which means have no capacity of giving his or her views, the best interest evaluation process should be carried out. The doctor should consult the relatives of the person concerning the issue if any. They should also assess the previous agreements in order see wh ether there was any document that the patient had written that could be of any help. The principle of the least restrictive alternative should be taken. The best option should be continuation of the process because it would of benefit to the patient and it would be the only chance for the survival of the person. Conclusion   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In conclusion, it is the right of every patient to give consent before any operation is undertaken although this seems to depend on the condition of the patient at that respective time. This would be for the benefit of both the physician and the patient. Based on the above case study and the English law, physicians are at risk of being sued upon failure of notifying the patient on the side effects of the operations. Many doctors prefer getting information from both the patient and the relatives to ensure balanced decision making that is not as a result of influence. The tort of negligence is also posed to be dangerous because it may lead to disablement or death of a patient if the doctor is careless. Both torts, the tort of negligence and battery are said to be the most violated by physicians References Beauchamp and Childress. The Principles of biomedical ethics, (1979) P. 3 Sidaway v.
