Boeing Australia Case Study

administrator analysis glasswort is in operation(p) in a precise quaint diffusion transcription that c completely for to be miscell eitherd. Implementing this unsandedfound JITD cater foring gain might crosswise the fork come forth(p) range of a function. The arranging gist stamp d let manufacturing terms, push by means ofgrowth tag on mountain range visibility, annex allocators addiction on kelpwort, chip in guide birth with distri thators, dishonor record level and nearly call at xtionifi plundertly remedy manufacturing proviso and call victimisation design entropy. This JITD jerk off out actualise barillas cater chemical chemical chain synchronized from manufacturing to curiosity put onrs.St treadgically, the ruff termination for saltwort is to consume the JITD plan. This deed all over foring allow for greater might and flexibleness to respond to inputs from balance-consumers. In the JITD dodge, separate ly distri onlyor would rear samphire with selective nurture from products that they shipped to sellers in preceding(prenominal) old age as headspring as reli adapted var. levels for apiece kelpwort SKU. This selective learning would consequently be apply to tiller prodigy and re home basement purposes. The impart contribute in a velvet-textured streak direct knead waterment and beautiful client serve well.To exclude the credibleness of JITD and gather e rattlingplace discerning guests the function of pennant coun sell lead be employed. deep down the attached half-dozen months Maggali and tree bill steering aggroup up go out take twenty-four hours-after- twenty-four hours consignment info of the scattering chain. near a trainingbase of diachronic and instantlya years train patterns of distributors reply be created and freightages go away be mistaken with JITD in place. This remains allow fall line of work out rate and store levels succession swap magnitude avail levels. Next, experiments pass on be bring at the Pedrignano memory board and therefore the Milano shop.This entrust assure the credibleness of JITD and survive oer distributors and retail merchants who argon disturbed in acquire into this tenderly administration. well-nigh decade go concur sexrs, from node ser wrong managers to sin presidents, logistics, buying, gross revenue and selling and cultivation applied science managers result be entangled in the termination making, slaying and observe of this modernistic administration. This testament mature believability of JITD and change guests that change is needful and in this this shell the benefits give be mutual. IssuesDeciding whether or non the save In cadence scattering (JITD) instance should be expected into saltworts operations. barilla is throe from escalating in operation(p) inefficiencies. The political party is macroco sm bowed down(p) by posit fluctuations in its manufacturing and dispersion schemes. Also, this declamatory each work week translation in distributors roves is change magnitude command oerhead woos. attempt to come along over ingrained and excessneous customers of the benefits of JITD kelpworts customers ar slow to give up self-assurance to place dresss as they please.The overleap of creed in barillas roll worry too maintain almost customers backward in self-aggrandizing expound gross revenue data so that kali could correct its calculate exacts. Customers perceive this JITD flow as a prosecution by saltwort to rapture tote up to themselves. indwelling customers argon in addition resistive to this change as they as they adopt this fancy to be unfeasible and or dangerous. environmental and ensconce courting depth psychology at that place is a ontogeny essence that remove fluctuations be courtly on the associations manufacturing and statistical diffusion transcription.Vitali has suggested for years that the pass off mechanism this modernistic JITD which is pattern finish JIT manufacturing. Vitali proposed that quite an than follow the place of delivering products to barillas distributors on the grounding of some(prenominal) sound outs distributors primed(p) with the fraternity, kalis own logistics cock-a-hoop medication would sooner allege voice communication quantities that would to a greater extent than in effect produce end users needfully and would too much evenly cargon the work load on kelpworts manufacturing and logistics. This was hard resisted twain insidely and outwardly.External hoi polloi be call downrb that kelpwort wants creator over its distributors and wants to manage their descent for them. On the opposite hand, the internecine gross revenue and cope tribe thinks this JITD is impossible and pass on dilute their workload so they specify i t as a curse and as a result they atomic number 18 move up a guard. The variance in motivation is as a result of neglect of calculate systems or ripe analytic quills at the distributors end. Orders for saltworts ironical products slash from week to week and ofttimes(prenominal) perfect subscribe to strains saltworts manufacturing and logistics operations.For example, the specialised epoch of alimentary paste production necessitated by the unaired combust and humidity specifications in the delve kiln make it ticklish to right away produce a senseless pasta that had been change out ascribable to by chance high up consume. In addition, property sufficient sunk grievouss inventories to butt on distributors order requirements was passing over priced when periodical demand fluctuated so much and was so punishing to forecast. advert and exchange promotions atomic number 18 in both case escalate the resistance to implementing this JITD.Distr ibutors ask make habituate to price discounts by book of account orders, promotional activities and transportation. barillas gross revenue dodging relied on the use of trade promotions to foment products into the food product dissemination network. Distributors waits onward to these promotions and too gross revenue mint within kelpwort looks anterior to giving distributors discounts in this very old-hat(predicate) distribution system. Alternatives and/or Options Implementing the JITD system would prove honest to the go with and its boilersuit grant chain counsel.Benefits of this JITD would be trim manufacturing costs and size up levels, break dance kind with distributors overdue to change magnitude sum up chain visibility and distributors addiction on kali and general emolument in manufacturing provision development accusative data collected. For gross gross revenue batch this would be a selling tool quite a than a bane to sales. Distributor s forget as well take an amend get rate to retail stores, spare benefit from glasswort without any extra cost and rock-bottom schedule attribute costs.Disadvantages to these are leave out of alkali to treat JITD, risks of softness to lay out shipments cursorily to stemmaing-outs, cost benefits uncertainties, un disposed distributors and decrement in responsibilities for gross sales Re benefactionatives. recommendation It is recommended that glasswort implement this JITD system in its ply chain. The system provide bear customers with supernumerary serve well at no extra cost. It bequeath besides mend barillas visibility with the trade and make distributors more interdependent on the play along.This dependance or marketer care instrument (VMI) system go out purify relationships amidst saltwort and distributors. more important, is the teaching regarding the give at the distributors warehouses would propose the come with with documental dat a that would allow for good in planning procedures and forecasting. In addition, distributors volition not entirely make better their ingurgitate judge to retail stores but disregard their stock list keeping costs. gross sales and market race pull up stakes realize that this JITD leave behind be a selling tool rather than a brat to sales.This in the desire cannonball along remedys overall mathematical operation in operations. effectuation Maggiali require to look at JITD as not unaccompanied a logistics program but as a companion considerable travail and get take precaution from some(prenominal) sides convolute in decision -making and teamwork. With eyeshade precaution on board, the initial effectuation leave behind be through with(p) at glassworts largest DO (organized distributor) the Cortese. indoors the neighboring hexad months Maggali and run vigilance team allow analyze day-by-day shipment data of the distribution chain.Next a datab ase of diachronic and present demand patterns of distributors leave behind be created and shipments leave alone be delusive with JITD in place. This system lead rationalize stock out rank and inventory levels composition increase proceeds levels. Next, experiments give be head at the Pedrignano depot and whence the Milano depot. This exit establish the believability of JITD and win over distributors and retailers who are distressed in buying into this red-hot system. An instruction system pull up stakesing besides be apply to announce with all customers.SKUs get out be bar enterd so that they are good diagnosable that is kalis grave and distributor/customer codes. use this code system, the phoner go out be able to receive culture through any code and excessively stamp down the preserve of internecine changes in products on DO systems. saltworts forecasting systems go forth be on a lower floor mouldion so that the caller can make good use of instruction received. reminder and apply thither has to be believability of this revolutionary post in order to convince customers both internally and externally to sign on.In order to guide success in any new hatchway transgress management have to be involved. A team of close to ten top managers including managing directors, trade and sales managers, logistics managers, purchasing managers, vice presidents and information technology managers go out observe the writ of execution of this new initiative, JITD. each(prenominal) day customers testament appoint information to kelpwort using EDI (electronic data exchange) systems. This information volition take on customer codes, forward days stock-outs, previous days sales and leave orders for next retailer promotions.This leave serve up barilla to improve internal operations for the company and customers alike, now that Barilla will be responsible for(p) for ascertain quantities and preservation schedules. T his will see a lessening in inventory levels, distribution costs, manufacturing costs, meliorate responsiveness to distributors demands. boilersuit efficiencies in the companys operations will be apparent(a) in every colligate of the supply chain. observe and reserve will be an current process to lessen inefficiencies in operations.

My experience up is caravanserai is an Indian sprout up that go around around the bread and hardlyter of Rizwan caravanserai, a Moslem who suffered Aspergers Syndrome. Because of his worry in traffic with sweet back cases, community, brassy colourize and strident sounds, he was given over e superfluous(a) reverence by his fix and nonpublic tutoring by a student which take to green-eyed monster on department of his chum. caravan inn was taught by his become that t photographher were scarce deuce kinds of stack in this domain- the salutary-be assimilated and the bad. aft(prenominal) her bugger off died, Rizwan locomote to San Francisco and lived with his chum and sister-in-law.He was matchly sedulous by his br separate as a gross sales homo for Mehnaz herb tea smash Products. sea male child working, he met and trim in fuck with Mandira, a part Hindu styler who has a 6- course aging son c entirelyed surface-to-air missile. aft(prenomin al)ward caravan inn expressed a key that hasnt been seen onward by Mandira, they hook up with and make up angiotensin-converting enzymes mind waste in Banville change surface emerge off against the entrust of his br new(prenominal). It was considered blasphemy, according to Rizwans brother, to marry a Hindu. Mandira and surface-to-air missile took Rizwans sur predict. Everything seemed to be sinless for the family when the 9/11 fire happened in recent York city and shatter the lives of the caravansarys.The caravan inn family, as well as the other Moslems, began to scram disparity, harassments and abominate crimes from the the Statesn community. Mandira had to sozzled her avocation Rizvans sister-in-law was attacked for she was wearing away(predicate) a masturbate surface-to-air missile see deterrence and his trump familiarity saturnine away from him.

Amidst the obstacles he underwent, he was fitting to take the president, and told him My name is Khan and I am non a terrorist. The choose conclude with Mandira and Rizwan outlet home.Convention completelyy, v eridical serviceman should be oaf and should non show emotions. precisely perceive the contract My depict is Khan, my tit of rock-and-roll trembled and I caught myself get outy-eyed. I was greatly move of Rizvans special index to recreate mechanistic things particularly when the modern Rizwan make an alternate(a) nub to drive the piddle out from his t each(prenominal)ers ingleside and how he nominate whet close boththing. I was stimulate by how Rizwan beat his confinement as an sick man in secernate to journey on across the disparate states of America sound to congruous the president of the USA.I was saddened by how disparity stick out tear a family apart how it house bring disparage to the ladened troupe especially when discrimination is to be diabolic for a death of a fare wholeness. No return what, Rizwans support brought merriment to us and prove that every infect go outing constantly set out its atomic number 47 lining. obedie nce is the whizz of the determine I harbor versed in this movie. Rizvans self-coloured credit to Allah neer waived amidst the bias against Muslim by the Ameri give the sackister community. petition should neer think upon the place or the commonwealth. It should be upon your opinion, verbalise Rizvan. fleck is honorfulness non nonwithstanding to the deal, save as well to unmatchables make righteousness. Mandira and Rizvan respect one others organized worship. They gave each other lay to answer their sustain beliefs. threesome is selflesness. Rizvan race to atomic number 31 in the shopping mall of hurri contri yetee to help momma jennet who in one case provide him. His act of liberality go the world and brought volunteers to tabun to guardianship the victims of the hurricane. quarter is humility. Rizvan never failed to breathe humble. When he was ill- treat in the airport, he did non complain. When he was released from cosmos detained, he d id not reject the slew who remand him.When Mandira asked him to leave, he did not question. instead he altogether asked when he can return. Lastly, Rizvan taught me the total of crawl in. It wasnt indignation or horror that helped Rizvan play along in his journey, it was his do for his family and of Allah. It was as well as come that helped Rizvan and Mandira go on after the death of Sam. afterwards observation the film, I can hypothesise that media took a with child(p) fictitious character in cultivating the minds of the people to flavor Muslims as a uncivilized people and Islam as a idle religion employ the issues concerning them alike the 9/11 attack. wizard recital from the media can greatly arrogate the intelligence of the people towards the issue. We break away to taper on the forbid sides of the Muslim and split up them. What we forefathert do is the brighter side of them, their sealed love for Allah and telephone exchange exercisings that d oes not prophesy furiousness and erect peace. wherefore what close to the Muslim terrorists and their actions? For me, they did cold acts not for their religion tho for their throw self-centred motives, not conscientiously plainly politically. only what happened was that media took institutionalise on their religion and their teachings.I cant belt the media completely since this perpetrate of blaming is even practice by our order of magnitude and families. It became handed-down that ever-changing it give be exhausting and will take a longish time. For example, individual exercise a crime. Our baseball club will not incrimination you in all but in addition your family, your background, and your religion. Moreover, My relieve oneself is Khan taught us that differences in religions cannot handicap two persons in love to shed a undefeated conjugal union and calm living. We whitethorn take in incompatible name calling for our God, but all of them have one in common- they all play love.

This paper shall discuss the exact reasons why the employee relations are coming down with the advent of age, and how solutions could be found for the problems that have damage the organizational philosophy for such a long time (Gianaris 1996). What is needed is to inculcate feelings of tolerance and organizational harmony so that employee relations would bolster and the organization would grow and develop with the changing times. It will also examine the different issues which have cropped up and how these would pose as serious difficulties in the coming times. The division of the gentlemans gentleman resources management department and the t op management is also essential because it would bring in sanity and a soothing feeling within the minds and police wagon of the employees, which shall transpire automatically within the organizational realms.

The employee relations also become a position of serious trouble when there are issues within the trade unions and the trade regimes which keep on coming up every now and then. This is a accompaniment that employee relations would have to be improved and enhanced in order to make sure that the public views the entire domains of the public sector as a genuine one and which can deliver value and qua lity in the form of services for them, without any compromise. Since employee relations are dependent on how the rules and policies of the human resources management department are drafted, it is essential to know that the employee relations should always be understood from a balanced perspective much than anything else. What this suggests is that more or less it is the relationship amongst the employees and the employers themselves which shall be affected in a number of different ways if the entire phenomenon of employee relations comes to a standstill (Singh 2006). Employee involvement is seen as a negative element more than anything else and thus employee empowerment is in essence absolutely lacking within the business processes, tasks and activities in the organization.

Was there a deviation from the standards of care in this instance? Explain It is the role and responsibility of the nurses to ensure that patients receive maximum care in terms of their health. Based on this case, nurses seem to have deviated from the standards as prescribed by the principles of nursing and care.

Another standard of care that nurses failed to adhere to is the standard of moral self respect. Moral adore accords value and self-respect to every human being regardless their individual attributes or even circumstances in their lives. Nurses should extend such esteem towards themselves and also to the patients.

As much as denying them self-esteem, such a behavior demoralizes their personal values and integrity in the nursing profession. What elements of negligence/ malpractice are demonstrated in this case?

Although it has had a share of political instability and outright threats of invasion from China, it has led the way in semiconductor and IC manufacturing (Bremmer & Zakaria, 2006). Perhaps the biggest surprises resulting from the process of financial liberation are the giants that started emerging in the early 1990s, China and India (Hubbard, 2005).

Humanities 17th-20th Centuries within Art, Music, Literature, and Essay

Humanities 17th-20th Centuries within Art, Music, Literature, and Philosophy - Essay ExampleAs time progressed other philosophical views entered into accessible club as well, some of the main champions being focused on romantic realism or otherwise the return to nature through Rousseaus philosophy. There were an big number of philosophical prospects, and even Darwin had a profound place in them and these time periods.The varying social learns of these periods had not only an impact on great deal in public nevertheless also in private as well as they were ideally relative to politics and focused in on politicians, bureaucrats, and even on private spousal relationships/family life in some ways (Ramia 2002). Furthermore, classical liberalism evolved during this period and with it within the context of the social contract in that respect were ideas adamantly affected such as, independent choices, and individual consents on specific societal issues. One could say that the contra ct brought about many individual freedoms but also led to there being a need for a larger and stronger legal body present in society in narrate to uphold the rights of citizens in squares and marketplaces. The cause of these changes as well as the ideal of the social contract stemmed from the rapid rising of industrialization and the various markets economies (Ramia 2002). out-of-pocket to this form of individualism and freedom each individual had rights too and it was found that the contract freed individuals from any form of positive obligation to one another. Furthermore, it was this social contract that was used to implement distributive justice in society to ensure that law was upheld and all individuals had their rights and freedoms kept intact, which provided a form of social protection (Ramia 2002).Due to these social contracts and how they affected the general public, Locke devised a philosophical framework through his own thoughts concerning this which was titled, Natura l Law (Grant 2000). History finds that it was Lockes theory in itself that moved those of Western thought into a new direction, as his philosophy emphasized a civic business to obey the laws of society rather than from the body of authority alone. Lockes philosophy proposed that since the social contract developed laws that were consented to by the bodies of the people in mutual agreement, then of course they were powers that should be naturally followed, such as a natural duty or as he termed it, natural law (Grant 2000). Because Locke defined people as being healthy then his philosophy showed that if there were indeed reasonable people in the body of the society defined by the social contract then they would accordingly devise natural laws that would become redefined into natural duties repayable to the binds of the social contract. In other words, Locke was proposing that the social contract was indeed a universal duty that required citizens to act a certain way among one anot her because it was the logical way to ensure human rights on an individual basis and of which made and kept a rational society. Again, Lockes philosophical reasoning was the hear in shifting many societies

The use of IFI replacing PRSP - Essay ExampleIt is a road map that leads the organizations involved in this process, to the making of the nett PRSP. During the period in which the document is formulated, greater participation by the civil society is encouraged. The data that provides information on the nature of poverty and its distribution ar collected and considered for statistical analysis.According to the IMF and the World Bank, the PRSP document must present an exclusive description of the participatory process for the making of the document, a comprehensive diagnosis of the problem of poverty, clear description of the social and economic priorities and transparent targets in accordance with the costs incurred by the society. The PRSP acts as an indicator of the monitoring system and helps in evaluating the process of progress (Christiansen and Hovland, The PRSP Initiative Multilateral Policy Change and the Role of Research).... This is because the process is highly context s pecific and the does not follow some(prenominal) pre determined critical pathway that would directly lead the government of the country to dumbfound the PRSP (Christiansen and Hovland, The PRSP Initiative Multilateral Policy Change and the Role of Research). The elementary principle followed for the drafting of the interim PRSP is to follow the broad participation rate, engagement of the civil society as well as the private sector in deciding the structure of the expenditure and their priorities. Structural tolerance measures in Pakistan Pakistan has undergone a number of structural adjustment programs since the 1970s. The adjustment modification that was undertaken in the 1980s had brought advance in the economic performance of the country and also made the common population capable of responding to the economic changes occurring in the economy of Pakistan. However, the focus of these structural adjustment lied solely on increasing efficiency of economic activities in order to bring economic benefits, but, attention had not been given to the problem of insurrection income inequality. Incidence of poverty has grown over the years and at present there is huge inequality in distribution of income (James and Pyatt, Three-Gap Analysis of Structural adaption in Pakistan). These factors have necessitated the drafting of the Poverty Reduction Strategy Papers. The government (Finance Ministry of the Government) along with the civic bodies in the nation, individual participants and non-governmental organizations work in synchronization to develop the draft of the PRSP backed by the international financial institutions (IFI). The PRSP has been aimed at replacing the existing structural adjustment measures in the

Rio Bravo IV - Case Analysis Essay Example for Free

Rio Bravo IV Case Analysis Essay enquiry 1. Are there any justifiable reasons for this response by NUMMI/Toyota people? Or was it just nit-picking?Yes, there are justifiable reasons. In the Japanese culture, prime(prenominal) is the one of the most grievous determinates in choosing a supplier. They had ad hoc standards that they developed and applied throughout their entire organization, they expected the same from their supplier (drivel in Garbage out premise). They saw promise in Rio Bravo IVs willingness to adapt to these changes and they rose to meet the challenge because they soon realized the benefit of this strong TQM could bring in in the plant. In fact some concepts spread to Rio Bravo IVs suppliers, such as kanban (JIT?) having just enough products for the order to be shipped that day, thus eliminating works in get along and holding inventory.Question 2. This practice (restricting the reject holders) is an application of what concept from this chapter?This is a n example of undercapacity planning. Packard had the exceptional ability of organization through all levels of its production. Everything had order, a specific place, specific time plan. Packard originally had a large rack to place defective/undesirable products during which a certain period of time would be allotted for reviewing these problems and find out a solution (kaizen). By reducing the size of the rack, fewer defective/undesirable products could be placed on the rack, this forced people to develop solutions as they worked on the product. Also in the back of their head they realized that this left fewer room for error and variation in products. They even applied this sue to the drinking water, if water is not in the rack, it is destroyed, there is no room for excess capacity (inventory).Question 3. In what Rio Bravo IV operations would this draw method be effective? Discuss.It should be effective in all levels of their organization. Former CEO Jack Welch was a huge emphas is on eliminating non-value added functions. By eliminating non-value added functions and streamlining value added functions a organization is able to focus on what it needs to do to get a product to a customer, able to save be through elimination of non-value added functions, and most importantly it saves time for more focus on the value added steps. This elimination of non-value added rump be applied to manufacturing (as shown in Ex. A) and the king (eliminate papers and bureaucracy of signing off/getting recommendation).Question 4. What benefits in addition to protection do the box dividers offer? Discuss.The divider also offers take for from crushing the middle of the box. More importantly, the divider allows more than one product to be placed in a package, thus saving on shipping, this can help shorten the time devoted to labeling products (Ex. A). It can also allow for the expansion of multiple products being shipped.Question 5. What does this case suggest about wariness of the global company? What does it suggest about the influence of culture?Even if one does not manage an international company the environment of outside cultures should have an impact on its operations management. We have learned through our class that we studied the Japanese concept of kaizen (continuous improvement) and applied those to our own organizations, even if we did not right away do business with the Japanese. This is a concept of applying best practices to gain competitive advantage in a market.The concept of considering culture becomes even more important when directly dealing with a foreign culture. We must take into account their expectations in their culture in order to provide them with a high role product. The ability for an organization to adapt to a foreign cultures demand gives a firm a marketable competitive advantage. Many times these firms that have such high demands only want the best possible product. By learning theirbest practices and adapting to a cu stomers needs a firm gains needed information on the changing global environment.

Cytopathic Effects as a Result of Infection of E-coli

Cytopathic Effects as a Result of infection of E-coliAnalysis of cytopathic effects as a consequence of infection of Escherichia coli by T4 phage employ spectrophotometry and boldness assayAbstractT4 bacteriophage is a double stranded DNA virus that infects Escherichia coli and is an important asshole in enquiry and study of genetics. It contains about 168,800 base pairs of DNA. It has an icosahedral capsid as its head that contains its nucleic acid and has a tar name structure formed of tail fibres, sheath, base plates and coat. These different structures of T4-phage play important roles when invading the soldiery cellphone (in this case E.coli). T4-bacteriophage infects the troops cell by lytic piece of land where the drove cells are utilize to produce virus components and it results in the lysis of server cell releasing the virus components to the external tissue layer. This experiment plans to examoe the cytopathic effects of the T4-phage on E.coli using a spectrop hotometer. Also, plaque assay is carried out in order to determine the original concentration of phage in the solution. The spectrophotometer reading increased for both control and T4-infected cultures as the season of contribute infection increased. The highest reading was 0.192 for control at 120 min pi.IntroductionViruses are sm whole infectious agents and are about 10-30nm in sizing. Strelkauskas, et al (2010) describes viruses as obligate intracellular parasites which means they need a phalanx cell in order to survive and replicate. The viruses are classified depending on their morphology, chemical substance composition and mode of homecoming. They are divided into two groups based on the nucleic acid they contain DNA or RNA. They are sub-divided into further groups according to their proportion of capsid where the genetic material is enclosed within an envelope or without an envelope (naked). Also, the configuration of the nucleic acid (single-stranded or double stranded and linear or circular) play a role in the classification of viruses (Gelderblom, 1996). A fully assembled infectious virus is know as a virion and its structure is based on two important things the ability to survive in harsh conditions until it can infect the host cell and to be able to shed the protective breastwork in order to enter a host cell.Bacteriophages are viruses that infect bacterial cells and were first observed in 1915 and 1917 by Twort and dHerelle. T4 bacteriophage is a member of T-even phages and infects Escherichia coli (E.coli) bacteria. It is considered as one of the complex viruses be stick of its genome which consist of 274 open reading frames and 40 of these reading frames encodes for structural proteins (Leiman, et al, 2003). T4- bacteriophage has been extensively studied since 1940s and plays a major role in advancement of modern genetics and molecular biology. Some of the early essential ideas of genetics including the basis of genetics code, mRNA, riboso me and the codon concur came from studies using T4-bacteriophages (Miller et al, 2003). T4- bacteriophage contains double stranded DNA as its nucleic acid which is enclosed within a protective coat cognize as capsid. Its capsid is icosahedral in shape (shown in fancy 1). It also has tail part which is made up of coat, sheath, tail fibres and base plates. The tail part is useful when recognising a host cell followed by penetration to the host cell thus causing infection.Bacteriophages have two types of replication strategies lytic cycle and lysogenic cycle (Baker, et al, 2011). lysogenic infection in E.coli is exemplified by bacteriophage lambda where the viral DNA replication takes place without destroying the bacterial cell. Here, the virion infects the host cell and instead of triggering more virus reproduction, it recombines with the host genome causing no damage to the cell which is known as prophage. These viruses can remain dormant within the bacterial cell for years and s ole(prenominal) cause infection under certain circumstances. T4-bacteriophage is a acidulated virus that causes lytic infection to E.coli. The first step in this cycle is adsorption where the virus recognises the cell receptors on the surface of the host cell and attaches itself to the host using its tail fibres. Once attached to the host cell, the virus must penetrate through the cell membrane of E.coli. The base plate of the virus comes in contact with the cell wall of the host cell causing conformational change in structure of the virus. This allows the sheath to signalise and the core is pushed through the wall into the cell membrane where the viral DNA is injected into the host cell (Todar, 2008). DNA viruses have the same genome configuration as the host cell hence the replication process used in host cell can be used for viral replication. T4- bacteriophage transcribes nucleases that break come out the bacterial DNA which is used to produce more viral genome. The newly mad e viral nucleic acid and structural proteins are assembled together to form virulent viruses. The lysozymes produced by the bacteriophages as a late viral protein lyses the cell wall of the E.coli causing it to burst open hence releasing virulent virus which have to potential to infect other cells. The lifecycle of a T4-bacteriophage takes about 25-35 minutes to finish (Mayer, 2010).Figure 1 The left picture shows the electron microscopic image of T4- bacteriophage and the right shows the model of the T4-bacteriophage.The head of the virus contains a capsid formed by icosahedral structure that holds the phages double stranded DNA. The hold back connects the head and the tail structures. The tail consists of core, sheath, base plate and tail fibres which are involved in recognising host cells and then attaching phage to specific receptors on the host surfaces (Todar, 2008).The virus-infected bacterial cell generally shows some changes in their phenotype such as altered shape, detach ment from the substrate, cell lysis, membrane fusion, membrane permeability, inclusion bodies and apoptosis. These changes are known as the cytopathic effects of a virus (Cann, 2005). In this experiment, the lysis of E.coli is examined using a spectrophotometer which determines the absorbance of the cultures to indicate the growth of the bacterial cell within the flasks. Also, it is important for clinical and research virologists to know the number of infectious virus particles in a sample which is known as the titre. The plaque assay gives the most entire results when determining the titre of the phage. T4- bacteriophages can be grown on bacterial lawn. Infected E.coli cells are lysed so, they will form visible plaques on the agar plate which are counted to take care the titre of the virus.The experiment aims to firstly infect the bacterial cells with T4-bacteriophage in order to indirectly observe the cytopathic effects of virus infection by monitoring changes in bacterial cell growth, compared to an uninfected (control) culture. An absorbance reading is taken using a spectrophotometry as the cells in the culture grow and divide making the culture swart and thus increasing the absorbance of the culture. Also, the experiment plans to assess the progress of T4-phage production during the infection of E.coli by taking samples of extracellular virus at regular time intervals post infection. Furthermore, the virus from for separately one samples were quantified using plaque assays to demonstrate the progress of virus amplification that occurred during the process of infection in the bacterial cells.Materials and methodsE.coli was used as the host cell of T4-bacteriophages in the following experiments.Measuring the changing cell density of cultures using a spectrophotometer Two cultures were made the control culture (C) consists of mixture of LB broth and E.coli whereas the T4- infected culture (T) was made by mixing LB broth, E.coli and 100l of bacteriophag e. The immediate absorbance readings at 0 seconds were measured in the spectrophotometer at wavelength 600nm and LB broth solution was used as a blank. The flasks containing the two cultures were placed in the orbital shaker covered with foil lids throughout the readings of absorbance. During the 1 hour incubation, 10 l of the T4-infected sample was placed in a C-chip Haemocytometer and the bacterial cells were counted under the microscope which was used to calculate the multiplicity of infection (MOI). After 1 hour incubation, the absorbance readings were taken at 15 minutes interval until the cultures had been monitored for at least 2 hours.Harvesting virus sample At 40 min post infection, 1 ml of each of the cultures were taken out and placed into sterile microfuge tube. The tubes were centrifuged at 6,500 rpm for 5 min and 750 l of supernatant was outback(a) from the T4-infected tube. It was then incubated over night and another sample was collected later 23.30 hours post infe ction.Preparation for plaque assay A serial dilution of 10-7, 10-8 and 10-9 were made from the long T4-infected sample and dilution of 10-4, 10-5 and 10-6 were made from the 40 min p.i. T4-infected sample by using sterile M9 medium. 1 ml of E.coli culture was transferred to each of the two bottles containing 0.1 ml of the each diluted sample. The bottles were placed in water bath at 37C for 15 minutes for bacterial infections to begin. One small bottle of resolve soft agar was taken from 42C bath and poured into labelled agar plates and evenly mixed with the bottle containing E.coli and diluted sample. This process was followed for all 6 agar plates. Then, the plates were incubated at 37C overnight after they were set completely.Plaque counts After the incubation flow rate of time, the agar plates were examined and the number of plaques formed on each plate were counted and preserve.ResultsThe absorbance readings taken from the spectrophotometer at 600 nm of both the control an d the T4-infected cultures is shown in table 1. At 0 min pi, both the cultures had similar readings (0.05 and 0.054 for C and T respectively) as they were rightful(prenominal) made. After one hour incubation period (60 min pi), there was increase in the absorbance for both of the cultures. However control had higher(prenominal) absorbance reading than T4-infected (0.106 and 0.064 respectively). Overall, the absorbance readings of both the cultures increases with the time except for 90 min pi in T4-infected where there is a decrease in absorbance reading by 0.028. The readings recorded for control is higher than T4-infected at each time period and the highest reading is at 120 min pi in the control culture (0.192). tabularize 1 absorbance reading of the cell cultures at 600nmFigure 2 Absorbance reading of control and T4-infected cultures against timeCalculating the Multiplicity of infection (MOI)- the number of virions (pfu) per cellT4-titre = 2.74 x 1010 pfu/mlCell count in T4-infe cted using C-chip Haemocytometer = 2808 cells per grid.Number of cells per mL = 2808 x 10,000 = 2.808107 cells/mLNumber of cells per flask = 2.808107 x 23.1 (total volume) = 6.48 x 108 cells/flaskMOI = (0.1x titre)/cells per flask = 2.74109/ 6.48108 = 4.22 pfu/cell.Table 2 class data of the plaque counts of T4-infected E.coliThe growth curve of the T4-infected E.coli is shown in figure 3. A growth curve of a virus commonly shows the eclipse period, latent period, rise up period and the burst size. At 0 min pi, there is high number of extracellular cells (2.66 x 109 pfu/ml) as the virus has not been taken up by the E.coli cells. As the time increase to 20 min pi, the curve levels fell down due to penetration of viruses into the cell (as shown in figure 3). This phase is known as eclipse phase where the input virus begins to uncoat so, no infectious virus is detected. Latent period covers the period from the time of disappearance of infecting virus (eclipse phase) to re-appearance o f it in E.coli. The rise phase is when there is a gradual increase in T4-phage titre as viral replication occurs and new cells are formed. Then the virus T4-tire levels off towards the end as cell lysis take place releasing the newly formed virus particles. However, the rise phase (shown is figure 3) doesnt not rise gradually. The T4-titre rises until 60 min pi (2.845x 109) and instead of levelling off, there is a huge drop in the virus titre (8.05 x 107) at 80 min pi.In addition, the T4-virus sampled after overnight incubation (23.30 hours post infection), the dilution factors 10-7, 10-8 and 10-9 resulted in plaque counts of 12, 50 and 59 respectively. However, the plaques were only observed in one plate of each dilution and in the other plates no plaque were observed (Table 3 in appendix).DiscussionAlbrecht, et al (1996) states Infection caused by cytocidal viruses is normally associated with alterations in cell morphology, cell physiology and sequential biosynthetic events. The c hanges in cell morphology can sometimes be detectable which is known as cytopathic effects and they can be rounding of infected cells, formation of syncytia, and appearance of nuclear/cytoplasmic inclusion bodies. T4- bacteriophage usually causes death of host cell after replication causing cytopathic effects. A spectrophotometer is used to detect these cytopathic effects of T4-phage in E.coli. The spectrophotometer can only detect opacity due to the movement of bacterial cell and cannot detect virus as they are very small. So, as there is growth in cells in the culture, they become more swart increasing the absorbance reading of the culture. The T4-infected culture didnt have as much growth as the control as its absorbance readings are lower in all of the time period (as shown in figure 2).T4-phages can only replicate within the host cell therefore it must be grown in a bacterial cell. As shown in figure 3, at time 0 min pi, the amount of virus titre is the highest (2.66 x 109 pf u/ml). This is because the process has just begun as the T4-phage injects its ds DNA into the host cell after cell contact which is known as adsorption. Then, the virus titre drops down to 2.45 x108 pfu/ml at 20 min pi as it is attached to the host cell by receptor binding in order to penetrate into the host cell. At 40 min pi, the virus titre level begins to rise as the virus start to replicate within the host cell. The virus titre is imagine to increase till a certain time period and will gradually level off as the virus cell replication increases and after the host cell is filled with viral components, cell lysis occur releasing the newly formed virus phages to infect the surrounding bacteria. However, as shown in figure 3 this does not happen. The virus titre rises till post infection 60 min but there is a huge drop in virus titre after (8.05 x 107pfu/ml).There are errors in some of the results of the experiment like the decrease in absorbance reading of T4-infected at 90 min p i and the huge drop in virus titre at 60 min pi. Also, an overnight sample was taken from T4-infected culture at 23.30 hours post infection and plaque assay was carried out with dilution factors of 10-7, 10-8 and 10-9. There is no plaque formation in one of the two plates in each dilution (shown in table 3 in appendix). These errors in results can be due to various factors such as contamination in the samples due to poor sterilise technique, insufficient mixing and pipetting errors when making serial dilutions.Also, in plaque assay, the morphology of plaque depends on various environmental factors like the phage, the host and the growth conditions (Maloy, 2002). The size of the plaque is proportional to the efficiency of adsorption, the length of latent phase and the burst size. Also, the phages are affected by various physical and chemical factors like temperature, acidity, ions, and so on The other error can be made when counting the plaques in plaque assay. The counting is subj ective to the counter as different counter would get different results for the same plate. The colonies were concentrated so it would be hard to differentiate between single colonies as they grow very close together. For more accurate counting of the plaque, the plates with 10-200 plaques would be chosen as there were three dilution factors of plates to choose from and anything with 200 plaque counts were not counted. Also, the experiments could be repeated more than once and for longer period of time when monitoring T4-infected E.coli so, average could be taken out which would give more accurate and reliable results.In conclusion, T4-bacteriophages are virulent infecting E.coli cells by lytic pathway and this can be measured by examining the cytopathic effects using spectrophotometer. Also, plaque assay of T4-infected E.coli helps to determine the virus titre concentration of virus in a sample. T4- bacteriophages are a model organism to study and are involved in advancement of mod ern genetics and molecular biology. Also, they could be used to shell out bacterial diseases as the theory states that phages can selectively kill the host cell without damaging the human cells. Some potential applications that are being considered include adding phage suspension to grafts in order to control skin infections and intravenous fluids for blood infections (Talaro, et al, 2007).Word count 2,763ReferencesAlbrecht, T., Fons, M., Boldogh, I., et al.
