One day a small group of hearing teens invited me to try some stuff, and they showed it to me. It was white and powdery. I had no idea what it was, but my intuition told me that it was something bad. Looking back, I believe it was cocaine. Fortunately, at the time I had enough sense to say no. In the 70s, they didnt teach me about drugs and what little I knew came from reading.

Essay on british army Values and standards - 1839 Words

AC 63812 A British Soldier’s Values and Standards V A L U E S A N D S T A N D A R D S O F T H E B R I T I S H A R M Y FOREWORD BY THE HEAD OF THE ARMY Humans are naturally team players, we all seek the company of others and like to share our experiences. The British Army is the ultimate team. It has an excellent reputation across the World, which is built on trust. A lot is expected of you as a British Soldier; you will be required to serve in dangerous places, risk your life for your teammates and put up with uncomfortable conditions. Our Values and Standards are essential to the British Army, they define what the British soldier is. They are more than just words, we must all believe in them and live by them. I expect you to†¦show more content†¦If you lack integrity, your teammates cannot trust what you say or do; they cannot rely on you and your team will suffer. You must look after your integrity as, like trust, once it is lost it takes a long time to earn back, if ever. V A L U E S Loyalty A N D S T A N D A R D S O F T H E B R I T I S H A R M Y SUPPORT THE ARMY AND YOUR TEAMMATES Loyalty is about supporting your teammates, looking after and helping them, putting their needs before your own, not letting them down, even when the going gets tough. In return, they will do the same for you. However, loyalty does not mean you should cover up for illegal or unlawful acts committed by your teammates as that would show a lack of integrity and moral courage. V A L U E S Respect For Others A N D S T A N D A R D S O F T H E B R I T I S H A R M Y TREAT OTHERS AS YOU EXPECT TO BE TREATED Soldiers come in all shapes and sizes and all deserve to be treated fairly. There is no place for any form of harassment or discrimination in an Army that claims to ‘Be the Best’. Discrimination damages teams; it excludes members and does not give them a chance to contribute. The Army recognises the importance of humour, but humour must be inclusive. Humour that insults, ridicules or intimidates people is destructive and damages the team. Respecting others is part of the trust that has to exist between you and your teammates; you must judge people on their abilities and not on their race, religion or sex.

The Mass Murder At The Bath School Disaster Essay

Renaissance Choir Finance Management System Free Essays

I will be making a system for the accounts of Renaissance Choir. Renaissance Choir are based in Emsworth and have 29 members. They sing at many events throughout the year and sometimes in Chichester Cathedral. We will write a custom essay sample on Renaissance Choir Finance Management System or any similar topic only for you Order Now They meet weekly. Statement of Problem Renaissance Choir require a system to manage their finances. It must be flexible and easy to use, so that anyone could come along and use it, without previous knowledge. Schedule of Activities Section Weeks Specification 1.5 Implementation 3 Testing 1.5 Evaluation 1 User Documentation 1 Total 8 Background The current system is based on two books containing input and output for the choir. All entries are written into the book by hand, and the books have to be carried to meetings when necessary and this is not very convenient, and rather slow. A computerised system would be more efficient. The system needs to deal with petty cash, as a constant amount is usually kept as a float or for occasions where cash is required and not a cheque or other method of payment. Overview As the system needs to contain columns of data, a spreadsheet would be most appropriate. I would use Excel, as I am well acquainted with it and it has many useful features that I can use to my advantage. My system would be composed of several sheets- a main sheet with buttons to move between sheets, then other sheets for data entry, listing the entries and making graphs and pivot table reports. Each sheet would have a button to link back to the main menu, and to other relevant sheets. For instance the data entry screen would have a button to submit the data into the spreadsheet, which would activate a macro and move the data. It would also have a button to move to the data-listing screen, which would have a button to link back. The graph page would have a button that would create a graph, and another to clear it. The exit button on the main screen may also clear the graph as well as exiting. Interview and Research Summary I gave a questionnaire to my end user, who filled it in. This has given me much background and other useful information, that can be used to help produce the system. Volume of Data The system will be updated on a weekly basis, so it must be relatively easy to add, delete and change records, as it will be used so frequently. However, cheques need to be paid in at random intervals, and the system will need to recalculate totals and other formulae after each of these events. It must also be able to cope with petty cash, which can fluctuate. Problems with the Current System Problems with the current system are its inability to transfer data easily between the two books and the balance sheet, the fact that it is slow and rather inefficient, due to having two heavy books to carry around. Hardware Full Potential To get good performance from the system, the requirements would be: 200 MHz processor speed 16 MB Ram 16 Bit colour graphics or better Software Full Potential The features of Excel that I will use to create the system are: macros, buttons and controls, formulae, charts, pivot table reports, visual basic, linked workbooks and Input and Output The user will enter data every week. The volume of data entered will depend upon how many events were held in that month, as each event will probably have inputs to the system in income and expenditure. At the end of each month and at the end of the year, the data will be summarised and the summary probably printed. Also, the system will process the lists of data to produce sub-totals and totals over different time spans. User Skill Level My end user is pretty skilled with computers, as she uses them in her work frequently. Therefore the system will not have to explain basic computer functions or other very basic ideas in the user guide, and the technical guide can be pretty complicated. Software Use I will produce the system, but on the main page I will hide the gridlines. I may do this on other pages as well, so that unnecessary gridlines are not shown- if I want gridlines to be shown, then borders can be put around required cells where tables are required. Also, anything that shouldn’t be altered (e.g. integral system parts) will be protected to prevent alteration. There will be macros to do things like moving between sheets and adding records. Objectives to Perform My end user wants the system to be able to: * Hold both income and expenditure in one place * Cope with petty cash that is used for floats at events and other purposes * Be able to transfer data between sections easily * Produce graphs and charts of the data * Produce summaries of the data Performance Indicators * Must be able to open relatively quickly, even on lower spec machines * Must be able to contain a large volume of data while still retaining a file size below 100 kilobytes * It must be relatively easy and quick to enter data or perform other operations * It must be relatively difficult to make mistakes while entering data (using drop-down lists, buttons, macros etc) * It must be easy to get to specific sections * It must be foolproof- e.g. impossible to alter critical system aspects * It must be possible to alter the structure of the database when necessary How to cite Renaissance Choir Finance Management System, Papers

Nak as a rice farmer relies on the earth and his crops but his environment makes this another hardship, the land is stricken with drought, want, disaster and death the fields are completely starved of water cracks of the parched earth this must make it extremely difficult to bring in enough food to feed his family which relies on him. We are shown Naks frustration at this angry at the weather capable of such endless torture Naks poverty makes his living conditions also harsh, the food they eat frogs with morning rice is very basic and must be monotonous and boring. But there is no money for Nak to spend on food, youre poor so they rely on what can be found around his home land snail or razor clam he would take these as well this diet must not be very healthy.

This behaviour from the government Nak must feel is a last hope for him and his family must be extremely de-motivating and must make Nak feel himself like he is born to suffer, youre at the end of your tether and you turn to the authorities only to be put down The final straw for Nak is having to leave is son in a state where he could die any moment, we see the sons good relation ship with his father, Pa, heres another one. Pa and when the snake bit Naks sons hand he carried his child this shows how much Nak loved his son. Nak is then faced with an awful decision to make, to stay with his dieing son and face jail if you dont go, you simply go to jail or leave his son, who could die at any moment. For Nak to make this decision is cruel and extremely unlucky, the timing of the government offering the money for families with five or more children and his son suffering a snake bite can only be seen as anything but lucky. Nak makes the harsh decision to leave his son in a critical condition to receive the money, which itself was very difficult, cant you see my boys gasping out his life? How can I go? He cried this shows Naks desperation and anger at the events. When Nak returns he finds his son dead. one more day and youd be out of two hundred baht although we do not find out Naks reaction to this, we know how much Nak cares for his son, and the final death of his son was surely heartbreaking. In conclusion, there are so many things which make Naks life anything but lucky; the environment he lives in, his poverty, hardship, treatment, living conditions, and most importantly the death of his son. All these reasons could easy make you believe the view that Nak was born to suffer.

Free Essays on Israel

The Palestinian President Yasser Arafat requested Israel’s new government to resume talks involving the Prime Minister Ariel Sharon. Arafat said that they are ready to resume negotiations with the Israel’s government, and immediately if necessary. Ever since Sharon had won a victory over Prime Minister Ehud Barak on Feb. 6, Sharon and Arafat have been undeniable enemies. Both of the leaders have seemed to put aside their difference unwillingly, in order to further negotiate talks. â€Å"Let the negotiations over the permanent status be resumed from the point it had left off,† Arafat said. â€Å"This is the only efficient and logical way to reach a clear security formula and a strong basis for coming agreements.† Sharon said that he would only resume talks with the Palestinians only if they stop the revolt that started after Sharon visited Jerusalem. Arafat must order his people to stop the violence in order to negotiate. Sharon said that once the negotiations begin he will offer the Palestinians only about 42 percent of the West Bank, in which they completely control now. But Arafat wants to resume talks where they left off, in which they would share Jerusalem and the Palestinians would get more than 95 percent of the West Bank and all of the Gaza Strip to compose a Palestinian state. In class we have discussed the issue of the Palestines and the Israelis and the conflict between the two. This is definitely a step in the right direction in order to have peace in this troubled area. With this area having so much valuable history it is a shame seeing it being destroyed the way it is. Fighting has been a reoccurring event in this area and peace talks are in desperate need. At this point in time the talks are in the early stages, but they are in the process of working things out. It’s definitely a shame to see the tragedies that are occurring but it is also good to see that they are atleast talking....

Arafat said that they are ready to resume negotiations with the Israel’s government, and immediately if necessary. Ever since Sharon had won a victory over Prime Minister Ehud Barak on Feb. 6, Sharon and Arafat have been undeniable enemies. Both of the leaders have seemed to put aside their difference unwillingly, in order to further negotiate talks. â€Å"Let the negotiations over the permanent status be resumed from the point it had left off,† Arafat said. â€Å"This is the only efficient and logical way to reach a clear security formula and a strong basis for coming agreements.† Sharon said that he would only resume talks with the Palestinians only if they stop the revolt that started after Sharon visited Jerusalem. Arafat must order his people to stop the violence in order to negotiate. Sharon said that once the negotiations begin he will offer the Palestinians only about 42 percent of the West Bank, in which they completely control now. But Arafat wants to resume talks where they left off, in which they would share Jerusalem and the Palestinians would get more than 95 percent of the West Bank and all of the Gaza Strip to compose a Palestinian state. In class we have discussed the issue of the Palestines and the Israelis and the conflict between the two. This is definitely a step in the right direction in order to have peace in this troubled area. With this area having so much valuable history it is a shame seeing it being destroyed the way it is. Fighting has been a reoccurring event in this area and peace talks are in desperate need. At this point in time the talks are in the early stages, but they are in the process of working things out.

Job Prospects for ESL Teachers in the U.S.

Job Prospects for ESL Teachers in the U.S. If youve ever thought about changing professions to become an ESL teacher, now is the time. Increasing demand for ESL teachers has created a multitude of ESL job opportunities in the US. These ESL jobs are being offered by states which are offering a number of job training opportunities for those not already qualified to teach ESL. There are two principle types of ESL jobs that are in demand; positions which require bilingual teachers (Spanish and English) to teach bilingual classes, and ESL positions for English-only classes for speakers who have a limited ability in English (LEP: limited English proficiency). Recently, the industry has moved away from speaking about ESL and has turned to ELL (English language learners) as the preferred acronym.   ESL Job Demand Facts Here are some statistics that point to the great need: According to the  National Center for Education Statistcs, In school year, 27 percent of all schools with bilingual/ESL teaching vacancies found them very difficult or impossible to fill, more than for many other teaching fields. Since this report, the number of ESL job vacancies has grown rapidly.From the same report: As the number of children with difficulty speaking English has increased (from 1.25 million in 1979 to 2.44 million in 1995), so has the burden on school systems to recruit teachers with the skills necessary to teach these classes. The difficulty schools have in filling such positions is one indication of whether the supply of bilingual and ESL teachers is adequate to meet the demand.The number of LEP speakers grew 104.7%, from 2,154,781 in 1989 to 4,416,580 in 2000 according to a survey performed by the National Clearinghouse for English Language Acquisition. Now for the good news: As a means of meeting the ESL job demand a number of special programs have been implemented around the United States for non-certified teachers. These programs provide an excellent means for teachers who have not taught in the State education system to take advantage of these opportunities. Even more exciting, it provides an opportunity for those from a wide variety of backgrounds to become ESL teachers. Some of these even provide a financial bonus (for example a bonus of up to $20,000 in Massachusetts) for joining their programs! Teachers are needed throughout the country, but principally in large urban centers with high immigrant populations.   Education Required In the U.S., the minimum requirement for programs is a bachelors degree and some sort of ESL qualification. Depending on the school, the qualification required might be as simple as a months certificate such as the CELTA (Certificate in Teaching English to Speakers of Other Languages). The CELTA is accepted around the world. However, there are other institutions that provide training online and in weekend courses. If youd like to teach in a community college or at a university, youll need at least a masters degree preferably with a specialization with ESL.   For those who would like to teach in public schools (where demand is growing), states require additional certification with different requirements for each state. Its best to look into the certification requirements in the state in which you would like to work.   Business English or English for Special Purposes teachers are in high demand outside of the country and are often hired by individual firms to teach staff.  Unfortunately, in the United States, private companies rarely hire in-house teachers.   Pay Despite the need for quality ESL programs, pay remains rather low except at larger accredited institutions such as universities. You can find out about average salaries in each state. Generally speaking, universities pay best followed by public school programs. Private institutions can vary widely from near minimum-wage to much better-paid positions.   To meet the growing demand for ESL teachers, a number of websites have created invaluable resources for the recruitment of teachers. This guide provides some tips on becoming an ESL teacher. Other opportunities are open to those who are in mid-career  or do not have the exact teacher certification required by any individual state for ESL jobs in the public school system. For more information on teaching ESL in the United States, TESOL is the leading association and provides a great deal of information.

Media, culture and society - Essay Example The BBC is a non-commercial and the most well-known public service broadcaster (PSB) in the UK. However, it was with the launch of the first commercial broadcaster ITV in 1955, which made the government formulate certain rules, wherein, the broadcasters were obliged to show a certain level of local news coverage, arts and religious programming. Later, with the launch of other commercial television broadcasters, the government started PSB channels like Channel 4 and S4C. Channel 4 catered to the minorities and arts, whereas, S4C focused on Welch language programs. Later, Channel 4 went through a restructuring under the Broadcasting Act 1990. Even ITV is attempting to restructure its model by reducing unprofitable PSB programming. The major reason for these PSB channels to restructure is due to the increased competition from the digital and the multi-channel television. Recently, even Ofcom has come up with a consulting paper to decide on what direction the PSB channels should take in the near future. The Ofcom in its report assessed the effectiveness of the designated public service broadcasters - BBC, Channel 3, Channel 4, Five, S4C and Teletext - in delivering the public service purposes set out in the Communications Act in the UK. The report also analysed "how the quality of public service broadcasting can be maintained and strengthened in future." Ofcom set a new framework for PSB that would be adaptable to "respond to and reflect changing technologies, markets, and the needs of citizens and consumers." The Ofcom in its report recommended the formation of a new Public Service Publisher, which would be flexible enough to adapt to the constant changes witnessed in the media industry in the contemporary world. The report also addressed the issue of the governance of the BBC. It stated that the governance framework should "support a well-run, strong, independent and properly funded BBC which operates consistently in the public interest." However, Ofcom also demanded to have a greater clarity between the functions of internal governance, the accountability of publicly funded bodies in broadcasting and of regulation for the broadcasting sector as a whole. The BBC, developed under the first Director General of the channel Lord Reith, had the mission to inform, educate and entertain. Although, being funded by the government, the BBC tried to remain independent from the government's interference, which has made the BBC a respected organisation throughout the world. However, the danger of being influenced by the government and the upper-class society always lurks on an organisation funded by the government. Further, BBC has also earned the reputation for 'cultural paternalism' and being 'popular with the upper-middle-class viewers'. This is also being attacked by the left-wing critics of the media time and again. The first challenges to the BBC's monopoly came in the early 1950s in a report by Ronald Coase, an economist with the London School of Economics and Political Science. Coase in his paper "The British Broadcasting Corporation. A Study in Monopoly" (Coase 1950) identified two clusters of arguments supporting the BBC's monopoly i.e. arguments from technical and efficiency considerations and arguments from programming considerations. Later, former Prime Minister Thatcher, set up the Peacock Commission

The Virgin Suicides by Jeffery Eugenides - Thesis Example A handsome young teenager named Trip Fontaine manages to charm Lux and also impress Ronald (the girl’s father). He gets the parent’s permission to take Lux along with other three girls (Bonnie, Mary and Therese) to a homecoming dance. That day on a football ground Trip and Lux have sex. This makes Lux miss the curfew and hence starts a torturous time for all of the sisters. They are taken out of the school and restricted to their house and their liberty is curtailed. In one incident the mother even orders Lux to destroy all the music records she has. After some resistance Lux submits to the demands. From here the lives of the sisters takes a downturn. Smoking and sex on rooftop become common features. A strange smell comes from the house and permeates the neighborhood. All these spectacles create a big interest of the neighborhood in the lives of these girls. It is during this time that the neighborhood boys, who are infatuated by the Lisbon girls, communicate with them by using various methods. For example, they play music records over the phone. All these activities don’t continue for a long time as in the end all the girls kill themselves. When invited by the girls to the house, the boys enter it and find all of them dead. Bonnie is found hanging in the house, Theresa takes overdose of sleeping pills and Lux dies of Carbon Monoxide poisoning. Although Mary doesn’t die immediately she takes overdose of sleeping pills and dies one month after putting her head in the oven. The girl’s parents sell the house and leave the neighborhood. For the senior thesis I would like to explore the relationship between parents and their teenage girls. In the novel parents tried to make their daughters happy by being more lenient in terms of permitting interaction with the opposite sex. But probably what the girls needed was more displays of love and affection. The theme of difference between perception and expectation of parents and teenage

The Modernist Concept Of Urban Design Cultural Studies Essay

The Modernist Concept Of Urban Design Cultural Studies Essay The development of our towns and cities is intrinsically linked to many architectural and cultural patterns and trends of the past. Indeed the Aesthetic and strategic practices of architecture and urban design contribute, through a complex of formal and informal processes, to the creation of urban cultures as well as giving shape to distinctive city image [Stevenson 2003].The social and technological changes which characterised the end of the 19th and start of the 20th centuries, created a momentum of change in the art, design and culture of Western Europe, and precipitated a shift in the ideas behind design and architecture, that laid the foundations for the evolution of the modernist movement. In essence the modernist movement fundamentally altered the way that those who designed the towns and cities we lived in, viewed their role, based upon utopian fancies, standardisation, new industrial materials such as re-enforced concrete, chrome and plate glass, abstraction and a vehement a mbition to make a new world, not just a new art [Hughes 2006]. In Britain, the modernist movement did not really develop until the late 1920s and early 1930s, when the formation of institutions such as the Congres Internationaux dArchitecture Moderne (CIAM), began to formalise and standardise the idea of modernist architecture, not just as a means to design buildings, but to construct a whole new way of living a style which would seek to incorporate the form follows form mantra into the design of our cities and towns [Gibbered 2008]. During this time, continued urban migration, and the idea of using modern technology to exhort profound and positive influences via the design of our surroundings, was embraced by the majority of society, and soon captured by the imaginations of the architects. As the urban populations of the UK continued to grow, a new approach to urban planning was required that would be able to meet with the increased demand for housing and amenities. The modernist concept of urban design, saw the traditional urban model for development in the towns and cities of Britain relatively low-rise streets, squares and urban blocks eschewed in favour of a rational, usually orthogonal, distribution of slab and point blocks set in park land and open space. The idea of this design was that, rather than being enclosed by buildings, urban space would now flow freely around them [Carmona 2003], and that the Le Corbusier view of eliminating the relative disorder of urban areas would be achieved. An important development in the design of our towns and cities was the idea of how we lived. In 1934, the idea of communal living was first truly experimented on the middle classes with the design of the Lawn Road Flats in Hampstead (below). This idea of a more minimalist, functional way of living was fairly revolutionary to these social classes at the time and lay the way for similar residential developments such as the luxurious Highpoint one in 1935. This idea of communal living began to filter down to all social classes in London (such as such Maxwell Frys Kensal House, the first modernist social housing project in Britain, which opened in 1937), and influenced the development of inner city housing, which continued for another four decades. Lawn Road Flats in 1934 Image taken from http://designmuseum.org/ During the post-war years, the devestation that many had endured seemed to re-envigorate the national psyche with an optimism, and to many there was a sense that here seemed to be a growing idea that this was a chance, not only to re-build Britain structurally, but also to take the nation in a new direction [Gibbered 2008]. Of course, the urban areas of our cities and towns had taken most of the fallout, and this opportunity was seized by modernist architects who believed that, by changing the design of how we lived in our cities and towns, they could provide ambitious solutions to solve extensive social problems. This opportunity, and apparent political will to develop and implement modernist was seen in many of the post-war constructions in Europe, and later through slum clearance programmes and subsequent road-building schemes [Carmona 2003]. In Britain, an extensive re-building project began (by the mid-1950s, 2,500 schools had been built and ten entirely new towns were either un der construction or in the early stages of development), and there was a growing need for a town planning policy that could accommodate the needs of these people. This requirement for rapid functionality opened the door for Modernists to begin reshaping the appearance of British towns and cities [Gibbered 2008]. One of the key ideas that developed at this time, and has shaped many of Britains urban landscapes, was the idea that new towns would be designed and built from scratch. Modernist urban space generally appears in its purest forms when built on Greenfield sites [Carmona 2003], and as such this design seemed to be perfect to implement when strategising the development of these new towns a sort of blank canvass for many modernist architects of the time. The idea was to be able to create an urban modern utopia, which would deliver British city dwellers from the dark failures of Victorian housing to a bright new world of clean, functional towns [Gibbered 2008], with there dispersed site planning, brick housing, and homey peoples detailing [Hvattum and Hermansen 2004]. These New Towns†¦examples†¦. Depicted the modernist urban landscapes, presenting idealised sanitised visions of streets, public spaces, and buildings in which the users are little represented [Larkham 1997]. The pattern of modernist development in our towns and cities continued to dominate for the next couple of decades and, by the 1960s modernism had become the lingua franca of British architecture, whether it be schools, office complexes, homes, or even the new towns as above [Gibbered 2008]. Although perceived as successful demonstrations of urban utopia, the modernist ideal in urban development will be forever synonymous with the disastrous implementation of public housing schemes. Modernist urban space had moved away from buildings as consituent elements in urban blocks (i.e. concrete terraced masses) defining streets and squares, to buildings as separate free standing pavillions standing in amorphous space [Carmona 2003]. These planned estates could cope with high densities of population, and would provide the amminities that a community required within segregated blocks. What has since prevailed, and was marked during †¦.. The modern estates instead fostered a sense of isolation and anonymity, and reduced any existing sense of community. The product was fatally flawed; large blocks simplified the land-use pattern, and the nooks and crannies that house economically marginal but socially desirable uses and activities [Carmona 2003]. The rush to build high and fast system-built blocks prefabricated towers which could be assembled on site as a mean of housing in the cities of the UK, and the idea that †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦ [Gibbered 2008]. During the early part of the twentieth century the transformations in terms of population, urban expansion, and a rapid development of communication and infrastructure, resulted in a society and a way of life bent on change and innovation, but also in instability, continual movement, and crisis [Hvattum and Hermansen 2004]. What now seems ill considered is that the visions for ideal cities, in particular those growing out of the modern movement in architecture, were diluted and warped by the messy business of reconstructing actual cities, filled with real people whilst operating within democratic structures [Jones 2004]. Somehow without any conscious intention on anyones part the ideals of free flowing space and pure architecture evolved into our present urban situation of individual buildings isolated in partking lots and highways [Tranick 1986]. Indeed, over the last two decades, the public criticism of this style of development in our towns and cities has resulted in an almost u niversally agreed idea that modernism, as a cogent philosophy of building a better society through architecture has failed [Gibbered 2008].

Cellular Basis of Life

What is Life? This perennial question the answer to which has somehow eluded the most brilliant minds. For while scientists have identified many years ago the right mix of the atoms and molecules that constitute cellular material, they have not succeeded in ‘switching it on’ to make it alive, or ‘breathing life’ into it (Rabago et. al,2006) In this module you will: a.

Articles about CellBBC NEWS-Last Updated : Tuesday, 20 November 2007, 16:42 GMT Stem cells are thought to hold huge potential for treating a wide range of disease and disability. Scientists around the world are working on techniques to Refine stem cell therapy. The latest technique, nuclear reprogramming, promises to solve some of the trickiest practical and ethical issues. What are stem cells? Most adult cells in the body have a particular purpose which cannot be changed. For instance, a liver cell is developed to perform specific functions, and cannot be transformed to suddenly take on the role of a heart cell.Stem cells are different. They are still at an early stage of development, and retain the potential to turn into many different types of cell. Why are they so useful? When a stem cell divides, each new cell has the potential to either remain a stem cell or become another type of cell with a more specialized function. Scientists believe it should be possible to harness this ability to turn stem cells into a super â €Å"repair kit† for the body. Theoretically, it should be possible to use stem cells to generate healthy tissue to replace that either damaged by trauma, or compromised by disease.Among the conditions which scientists believe may eventually be treated by stem cell therapy are Parkinson's disease, Alzheimer's disease, heart disease, stroke, arthritis, diabetes, burns and spinal cord damage. Stem cells may also provide a useful way to test the effects of experimental drugs. It is also hoped that studying stem cells will provide vital clues about how the tissues of the body develop, and how disease takes hold. Are there different types of stem cell? Yes. Scientists believe the most useful stem cells come from the tissue of embryos.This is because they are pluripotent – they have the ability to become virtually any type of cell within the body. Stem cells are also found within adult organs. They have not taken on a fina l role, and have the potential to become any of the m ajor specialized cell types within that organ. Their role is to maintain the organ in a healthy state by repairing any damage it suffers. It is thought their potential to become other types of cell is mo re limited than that of embryonic stem cells. But there is evidence that they are still relatively â€Å"plastic†. Can they be easily grown in the lab?Large numbers of embryonic stem cells can be relatively easily grown in culture. However, adult stem cells are rare in mature tissues and science is still working on ways to grow them in the lab in sufficient numbers. This is an important distinction, as large numbers of cells are needed for stem cell replacement therapies. Is the use of stem cells controversial? Very. Campaigners are vehemently opposed to the use of embryonic stem cells. These cells are typically taken from lab-created embryos that are just four or five days old, and are little more than a microscopic ball of cells.However, opponents argue that all embryos, wh ether created in the lab or not, have the potential to go on to become a fully-fledged human, and as such it is morally wrong to experiment on them. They strongly advocate the use of stem cells from adult tissue. What is nuclear reprogramming? A new technique, in which cells isolated from skin tissue called fibroblasts are modified by inserting gene-controlling proteins. This chemical cocktail causes the cells to be â€Å"reprogrammed† to take on the plastic quality of embryonic stem cells. Why is the nuclear reprogramming an advance?There are two big potential benefits. The current methods derive stem cells from from existing lab lines, but these cells are foreign to the body, and run the risk of rejection if used to repair or replace damaged or diseased tissue. Nuclear reprogramming can potentially produce a supply of stem cells derived from a patient's own tissue – avoiding the issue of rejection of the cells. Secondly, the technique does not require the creation of , or destruction of an embr yo, and so is not ethically contentious. Are there safety concerns? Yes.Some researchers fear that it is possible that stem cell therapy could unwittingly pass viruses and other disease causing agents to people who receive cell transplants. Some research has also raised the possibility that stem cells may turn cancerous. Work also still needs to be done to refine the new technique. Similar results were achieved by two teams using a different combination of gene-controlling proteins. In both cases the success rate in producing new stem cells was also low. Last Updated: Monday, 8 January 2007, 08:58 GMT ‘New stem cell source' discoveredUS scientists say they have discovered a new source of stem cells that could one day repair damaged human organs. Researchers successfully extracted the cells from the fluid that fills the womb in pregnancy and then grew them in lab experiments. The types of stem cell with potentially the most use have so far been deriv ed from specially grown human embryos. But this has created ethical concerns because the embryos are destroyed in the process. Opponents say this is tantamount to cannibalism. Supporters say stem cells offer real hope in treating illnesses like diabetes, Parkinson's and Alzheimer's.Implanted in mice Writing in Nature Biotechnology, the scientists said it should be possible to harness the cells' ability to grow into different tissue to treat disease. â€Å" It shouldn't be seen as a race between embryonic stem cells and other sources † Prof Colin McGuckin Newcastle University However, UK experts had doubts about the feasibility of the technique. They said gathering amniotic fluid from large numbers of women might be difficult. Amniotic fluid contains a large number of cells, many of which come from the developing foetus.The team from Wake Forest University School of Medicine, in North Carolina, extracted these from fluid samples taken as part of unrelated diagnostic tests duri ng pregnancy, then encouraged them to grow in the laboratory. They found that they had the potential to turn into a wide variety of different cells – the hallmark of potentially useful stem cells. They then transplanted them into mice, and carried out further tests to look at how they performed in a living creature. Again, the results were encouraging, with the stem cells spreading and starting to produce key body chemicals in both brain and liver.Bone stem cells introduced onto an artificial ‘scaffold' then implanted into mice also appeared to behave in a similar way to normal bone cells, forming bone even months later. Great interest The conclusion of the researchers was that the amniotic cells were ‘pluripotent' – capable of becoming many different cell types, and that they held the potential for treatment – particularly on the child from whose mother they were taken, for whom they are an exact tissue match. Dr Paolo De Coppi, now of Great Ormond Street Hospital, who worked on the study, said the amniotic stem cells were similar to, but not identical to, embryonic stem cells.He said: â€Å"Our research suggests that for some clinical applications they may work better than embryonic stem cells. â€Å"For example, embryonic stem cells injected into muscle can form teratomas – amniotic stem cells do not do this. â€Å"However, the range of applications for these stem cells may be more narrow than for embryonic stem cells. † Dr De Coppi it might be possible to take amniotic stem cells from a child diagnosed before birth with a problem, and use them to grow new tissue in the laboratory, which would be ready to use to treat the child when it was born.In theory, it might also be possible to genetically modify a foetus' own stem cells and inject them back into the amnioitc fluid to correct gene disorders. Possible limitations Professor Colin McGuckin, from Newcastle University, is researching the use of similar cells taken from the umbilical cord at birth. He welcomed the report, saying that it was ‘thorough' and demonstrated the potential of amniotic stem cells. â€Å"The best thing is to have a variety of stem cell sources to provide the best stem cell for patients. Unless researchers do work to demonstrate there are alternatives to embryonic stem cells, the wider public won't understand that. It shouldn't be seen as a race between embryonic stem cells and other sources. † However, he said that harvesting amniotic fluid presented particular difficulties in many cases. â€Å"If it is a natural birth, the waters break and they are all over the floor, and you've lost them. In this country, the majority of women give birth naturally, which means that fluid could not be collected. â€Å"You could conceivably gather amniotic fluid during a caesarean section, but that process could interfere with the experience of giving birth. † Wednesday, 15 November 2006, 18:00 GMT Stem cells ‘treat muscle disease'A stem cell breakthrough could lead to a treatment For muscular dystrophy (MD), research has revealed. An Italian-French team found transplanting stem cells into dogs with a version of the disease markedly improved their symptoms. Writing in the journal Nature, the team said the work paved the way for future trials in humans. Scientists said it was a major step forward and bolstered the idea that stem cells could be used to treat MD. â€Å" This is the first piece of research that has convinced me that stem cell therapy could play a role in treatment for Duchenne muscular dystrophy † Professor Dominic WellsMuscular dystrophy is a group of genetic disorders that cause the muscles in the body to gradually weaken over time and mobility to be lost. It shortens life span and there is currently no cure. The researchers, led by a team at San Raffaele Scientific Institute, in Milan, Italy, looked at the most common form of the disease, Duchenne muscular d ystrophy. This condition, which usually only affects boys, appears in about one in every 3,500 male births and is caused by mutations in a particular gene that lead to a lack of dystrophin, a protein involved in maintaining the integrity of muscle.The team had previously seen promising results when they injected stem cells into mice with a version of this disease, but turned to dogs for their next trial because they replicate the musclewasting disease more accurately. Mobility returned The researchers used a form of stem cells, gathered from blood vessels, called mesoangioblasts, which are â€Å"programmed† to turn into muscle cells. They isolated the stem cells from both healthy dogs and also from MD dogs, with the latter's stem cells then being modified to â€Å"correct† the mutated gene. The scientists proceeded to inject these different types of stem cells into dogs with MD.They found that transferring the stem cells five times at monthly intervals produced the bes t results. Overall, injections of stem cells taken from healthy dogs showed the most improvement. Four out of the six dogs who received these stem cells saw the return of dystrophin and regained muscle strength. One dog that was injected at an early-stage of the disease retained the ability to walk, and two dogs injected at a late-stage of the disease had their mobility returned. Of the remaining two, one died early and the other, the scientists believe, did not receive enough cells.The experiment to inject MD dogs with their own â€Å"corrected† stem cells proved less successful, although the dytrophin protein returned. This approach was investigated because, should stem cell treatment move into humans, it would mean patients could be injected with their own cells, minimising the chances of rejection and avoiding the need to take immunosuppressant drugs. The researchers wrote: â€Å"The work reported here sets the logical premise for the start of clinical experimentation th at may lead to an efficacious therapy for Duchenne muscular dystrophy. ‘Excellent work' Dr Marita Pohlschmidt, director of research at the Muscular Dystrophy Campaign, UK, said: â€Å"We feel encouraged by the work because the results provide initial evidence that we might be one step closer to a stem cell treatment for Duchenne muscular dystrophy. † Dr Stephen Minger, a stem cell researcher at Kings College London, said: â€Å"This is an excellent piece of work demonstrating significant functional improvement in a naturally occurring disease in dogs that is very similar to that in humans. Although it will likely to be some time before this work can move to humans, it is nevertheless an important study in developing therapies for muscular dystrophies. † Professor Dominic Wells, of the gene targeting group at Imperial College, London, said: â€Å"This is yet another example of the vital contribution animal research makes to the development of treatments for human disease. â€Å"This is the first piece of research that has convinced me that stem cell therapy could play a role in treatment for Duchenne muscular dystrophy. â€Å"Kay Davies of the MRC Functional Genetics Unit, University of Oxford, said: â€Å"The use of stem cells to treat human disease holds great promise, but the actual delivery of such therapy is thought to be many years away. † The data, she said, changed this view. However, she added that the researchers needed to find out why not all dogs responded positively. Wednesday, 8 November 2006, 16:48 GMT Cell transplants ‘restore sight' Cell transplants have successfully restored vision to mice which had lost their sight, leading to hopes people could enefit in the same way. UK scientists treated animals which had eye damage similar to that seen in many human eye diseases. They were able to help them see again by transplanting immature retinal stem cells into their eyes. UK experts welcomed the study, published i n the magazine Nature, saying it was â€Å"stunning† research. â€Å" This is a stunning piece of research that may in the distant future may lead to transplants in humans to relieve blindness † Professor Andrew Dick University of BristolIf the results can be translated into a treatment for human eye disease, it could help the millions of people with conditions ranging from age-related macular degeneration to diabetes. Once the cone and rod photoreceptors in a retina are lost, they cannot be replaced. While treatments are being developed which might prevent or delay the loss of these cells, scientists are also seeking to help those already affected. It is thought the retina is one of the best places to try out cell transplant therapy because photoreceptor loss initially leaves the rest of the wiring to the brain intact.But previous attempts to transplant stem cells, which can turn into any kind of cell in the body, in the hope that they will become photoreceptors have failed because the cells were not developed enough. Harvest In this study, funded by the Medical Research Council, scientists from the University College London Institutes of Ophthalmology and Child Health and Moorfields Eye Hospital transplanted cells which were more advanced, and already programmed to develop into photoreceptors. ? 1 – Early stage retinal cells are taken from a newborn mouse ? 2 – They are transplanted into the retina of a mouse which has lost its sight ? – The cells implant and connect with existing cells in the eye, restoring some sight to the mouse. The team took cells from three to five-day-old mice, a stage when the retina is about to be formed. The cells were then transplanted into animals which had been genetically designed to have conditions which meant they would gradually lose their sight – either mimicking the human disease retinitis pigmentosa or age-related macular degeneration. The transplants were successful; the photorec eptors implanted and made electrical connections to the animals' existing retinal nerve cells – key to allowing them to see again.Tests showed that the mice's pupils responded to light and that there was activity in the optical nerve, showing signals were being sent to the brain. Dr Jane Sowden, one of the study's leaders, said: â€Å"Remarkably, we found that the mature retina, previously believed to have no capacity for repair, is in fact able to support the development of n ew functional photoreceptors. † ‘Not false hope' To get human retinal cells at the same stage of development, however, would involve taking stem cells from a foetus during the second trimester of pregnancy.But Dr Robert MacLaren, a specialist at Moorfields Eye Hospital who worked on the research, said they did not want to go down that route. He said the aim now would be to look at adult stem cells to see if they could be genetically altered to behave like the mouse retinal cells. There are some cells on the margin of adult retinas that have been identified as having stem cell -like properties, which the team says could be suitable. Dr MacLaren stressed it would be some time before patients could benefit from such a treatment, but he said that at least it was now a possibility. Every day, I sit in my clinic and have to tell patients that there's nothing I can do. â€Å"I don't want to give patients false hope. But at least now, if I see a young patient, I can say that there might be something within your lifetime. † Dr Stephen Minger, a stem cell expert at King's College London, said: â€Å"I think this is important, superb research – it clearly shows that the host environment is important in directing the integration of transplanted cells. † But Andrew Dick, professor of ophthalmology at the University of Bristol, added: â€Å"As with any basic research we have to be careful not to overhype.Remove the Jello from the plastic cup onto the paper pla te. We had some problem with this. The students may need to run the knife around the very outside edge of the Jello to loosen it. There are some suggestions that you might spray the cup with Pam or some other non -stick material. We did not get a chance to try this yet. Running warm water over the cup may also loosen the Jello. 3. Cut the Jello/Knox in half and remove the top half. Turn over the top and set it on the plate beside the bottom half 4. Use the spoon to dig out a hole in the bottom half of the Jello/Knox cytoplasm . Just pushing the food pieces into the Jello causes it to crack and come apart, making for a very messy cell.Place the gumball in this hole to represent the nucleus of the cell. 5. Using the spoon to make spaces and your diagram as a guide, place the other cell parts into the cell. Parts can be put into both the top and bottom half of the Jello/Knox cell 6. Take the top part of the cell and carefully place it on the top. If the cell feels soft, you can put the parts back into the plastic cup, then turn it over onto the paper plate. Then carefully remove the plastic cup. 7. After reviewing the parts one final time, those students who wish to can feast on their cell. Please use clean spoons in case the spoon you were working with fell on the floor or the table. It's Alive, Alive.Background: You will be in groups of three, each with your own job. The jobs to choose from are Contractor, Architect, and Surveyor. Your job, as a group, is to build the most realistic life-like plant cell the world has ever seen. Problem: What does a 3-dimensional cell look like? What are the various parts of plant cells? Materials: Play-doe, food coloring or tempera paints (red, purple, green, blue, white), 1 pair of gloves, yarn or undercooked spaghetti, pepper, plastic-bubble packing, aluminum foil, plastic wrap, pencil shavings, scissors, 1 large knife, glue. Procedure: 1.Before we start be aware that on the final day you must present your cell to the class. 2. After you have decided upon your jobs, the Contractor and Architect will collaborate to design the plant cell. The design should be drawn up on a piece of paper that explains what materials will be used for each organelle. It should be colored the same color it will appear when it is built. Take your time and make a good drawing. This should be completed early on day two. Throughout this entire process the Surveyor should be writing down the order in which each organelle was designed and the order in which it will be built. Along with this the Surveyor must make a copy of the design that the group can use when building it.The Surveyor's job is to basically take notes all the way through, so if the final product doesn't come out as planned the Surveyor can look back at their notes and answer why. 3. After you have finished your design, hand it in and your teacher will approve it. If it is approved, you can start to build your cell. 4. Building should be the role of the contractor. Architect's watch the bui lders to make sure they are doing it exactly as planned. Surveyors should take notes on how it is built and also can assist the Architects to make sure it is being built as planned. It's Just a Phase They're Going Through! Problem: What phases do cells undergo during mitosis? What happens at each phase?Materials: Unlined paper (1 sheet), colored pencils, pencil, crayons, light microscope, slides, cover slips, onion (fresh), toothpicks, knife (used by teacher only), iodine stain. Procedure: Procedure Part A: Slide Preparation Onion Skin a. First take a piece of onion skin off the onion. b. Put it flat on a slide. c. Bring the slide to the leader for a drop of iodine stain. Data Sheet d. Carefully put on a cover slip remembering to angle it. e. Examine the cell under low then medium power. 1. Front f. Adjust your microscope to a higher power. 2. Procedure Part B: Data Preparation 3. Back 1. You will take your paper fold and it in half, label each ox created (front + back) numbers 1 – 4 as shown on the right. 4. 2. Create a large box within numbered box, as shown. 3. Within the large area you will draw the stages of mitosis, make them colorful. 4. Within the smaller box you will write the name of each stage shown, and give a full description of what you see happening.Cells Vocabulary Quiz Directions: Match the vocabulary words on the left with the definitions on the right. 1. tissue the central, essential, or highly concentrated part around which other parts are grouped. 2. vacuole a musical instrument consisting of a keyboard attached to a device that forces air through a number of pipes to produce a wide range of sounds; pipe organ. 3. chromosome storage areas of the cell known for storing mostly water and/or food. 4. chlorophyll (chlorophyl) the ground protoplasm of cells that is outside the nucleus. 5. cell membrane Shaped like a bean, this cell organelle helps take food and manuf acture energy from it. 6. chloroplastA struct ure inside the nucleus where RNA is transcribed. 7. cell wall the mass of like cells in an animal or plant body, esp. as they form a specific organ: 8. nucleolus Thin, intertwined pieces of DNA found in the cell's nucleus. 9. organ the green (in color) pigment found in chloroplasts where photosynthesis takes place. 10. cytoplasm Mostly made of cellulose, this is the tough and rigid outer layer of plant cells. 11. nucleus an egg shaped body that appears green from all the chlorophyll they contain.

Mayan Architecture Tulum lies on the coast of Quintana Roo, Mexico, which is on the eastern side of the Yucatan Peninsula. Tulum is different from most of the other Mayan cities because of its location, its defenses, and its time period. The name â€Å"Tulum† means wall, although that was a name given by Mayan descendants much later. The name Zama was most likely the original Mayan name. It comes from a modification of the word â€Å"Zamal† (morning), associated with the dawn (Mureiko). My visit to Tulum in the early morning was quite an experience and an amazing view. It is no wonder they named the city â€Å"morning.† The meaning of â€Å"Tulum† stands true however. The city is surrounded on three sides by a fortified wall that reaches heights of 16 feet at the doorways. The fourth side is a 40-foot high cliff that overlooks the Caribbean reef and ocean. Because the city was constructed on a cliff, Tulum was/is the only large and significant Mayan coastal city. Tulum was constructed during the Post-Classic Period (AD 925 – AD 1540), and was one of the last cities built by the Mayan people. It was constructed around the 12th century AD,Show MoreRelatedHistory, Tradition And Culture, Mexico1673 Words   |  7 Pagesindigenous people whose lifestyles are quite similar to those of their ancestors.
