Analysis of treatment - Diabetic Leg Ulcers Essay

Analysis of treatment - Diabetic Leg Ulcers - Essay Example The literature review has provided information to be used in changing the present tools One of the more novel approaches to advanced treatment of the diabetic ulcer today is light therapy. In this therapy, there is a light emitting diode used (LED) and a super luminous diode (SLD) that will deliver low intensity laser light. This treatment is used in synchrony with conservative sharp debridement, offloading, bioburden management, and advanced dressings. According to Sutterfield (2008), the patients tested resulted in a healed wound in 8 weeks of treatment. During this same time period Blume, Walters, & Payne (2008) compared negative pressure wound therapy using vacuum-assisted closure with advanced moist wound therapy. This was a randomized multicenter controlled trial. There were 342 patients enrolled in this study and the mean age was 58. . Patients were randomly assigned to either the advanced moisture wound therapy or the negative pressure therapy. Evaluation of the ulcers occurred for 112 days and then they were followed for 3 to 9 months. The results showed that complete ulcer closure occurred with vacuum assisted closure 43.2% of the time and 28.9% of the time with dressing and topical. Lavery, Boulton, and Niezgoda et.al. (2007), also completed a study comparing diabetic foot ulcer outcomes from negative pressure wound therapy with historical standard ulcer care. They did this by analyzing Medicare claims data of 1,135 patients with diabetic foot ulcers that were treated with negative pressure and reviewed the results of a controlled wet to moist therapy meta-analysis that was a randomized study. Within 12 weeks, the negative pressure treatment showed significantly better results than the wet to moist dressings Further, Fernandez-Montequin, Betancourt, Leyva-Gonzalez et.al. (2009) studied the use of intralesional administration of epidermal growth factor-based formulation (Heberprot-P) in treatment of ulcers. They found that

Form and Structure Essay Example for Free

Form and Structure Essay As an AS drama group, we carried out certain exercises on narrative structure, to identify ourselves with that used in the play. For instance, we each acted out a scene, illustrating an everyday activity such as waking and getting up. We then narrated these scenes first in the first person narrative, then in the third. This enabled us to identify with how Brecht wished his actors to perform, as by narrating our own actions in the third person narrative, we were detaching ourselves from the parts we were playing, and so were not thinking emotionally what should this character think and feel now, but rather thought, how should this character appear. This also enabled us to understand how the process of taking photographs of scenes and trying to identify what was occurring within that scene, helped Brecht decide if his actors were performing correctly. The Verfremdungseffekte were designed to expose the familiar; Brechts actors were to present things in their concrete reality so that the audience would be encouraged to think about what had given rise to situation depicted, in this case Hitlers, or Uis rise to power, and therefore consider ways to change those conditions in the future. * The Resistible Rise of Arturo Ui is divided into 15 scenes, some of which are subdivided into several sections identified by letters. These 15 scenes are then divided almost equally into 2 acts. This symmetry gives the play a degree of continuity, enabling it to flow smoothly. Scene 8 displays a structure unique from that of other scenes throughout the play. It is the scene in which the innocent fish is on trial for potentially burning down Hooks warehouse. He is being tried before a corrupt judge caused by the manipulation of the judicial system by Ui and his underlings. This scene is divided into seven parts, a to g. Each of these parts is shorter in length than that preceding it, hence quickening the pace of the play and building tension within the scene. The shortening sections also highlight Fishs plunge into a prison sentence, that which he is undeserving of.

Botanical Garden Importance Essay

Botanical Garden Importance Essay The topic for this essay is the role of botanical gardens in plant conservation. The essay will be divided into four main parts. The first part discuss about the botanical garden. This part will include the introduction, history and development, network and function of botanical garden. Second part will explain the importance of plant conservation and the global strategy for plant conservation. The third part is the role of botanical garden in plant conservation. The fourth part will be the example of botanical garden in Malaysia and its roles in plant conservation. The last part will be the conclusion of the essay. 2.0 Botanical Gardens 2.1 Introduction Botanical gardens or botanic gardens are generally well-tended parks displaying a wide range of plants labelled with their botanical names. They may contain specialist plant collections such as cacti and succulent plants, herb gardens, plants from particular parts of the world, and so on; there may be greenhouses, again with special collections such as tropical plants, alpine plants or other exotic plants. Botanical gardens are often run by universities or other scientific research organizations and often have associated herbaria and research programmes in plant taxonomy or some other aspect of botanical science. In principle their role is to maintain documented collections of living plants for the purposes of scientific research, conservation, display and education, although this will depend on the resources available and the special interests pursued at each particular garden. 2.2 History and Development The origin of modern botanical gardens can be traced to European medieval medicinal gardens known as physic gardens, the first of these being founded during the Italian Renaissance in the 16th century. This early concern with medicinal plants changed in the 17th century to an interest in the new plant imports from explorations outside Europe as botany gradually established its independence from medicine. In the 18th century systems of nomenclature and classification were devised by botanists working in the herbaria and universities associated with the gardens, these systems often being displayed in the gardens as educational order beds. With the rapid rise of European imperialism in the late 18th century botanic gardens were established in the tropics and economic botany became a focus with the hub at the Royal Botanic Gardens, Kew, near London. Over the years botanical gardens, as cultural and scientific organisations, have responded to the interests of botany and horticulture. Nowadays most botanical gardens display a mix of the themes mentioned and more: having a strong connection with the general public there is the opportunity to provide visitors with information relating to the environmental issues being faced at the start of the 21st century, especially those relating to plant conservation and sustainability. 2.3 Network Worldwide there are now about 1800 botanical gardens and arboreta in about 150 countries (mostly in temperate regions) of which about 400 are in Europe, 200 in North America, 150 in Russia and an increasing number in East Asia. These gardens attract about 150 million visitors a year so it is hardly surprising that many people gained their first exciting introduction to the wonders of the plant world in a botanical garden. Historically, botanical gardens exchanged plants through the publication of seed lists. This was a means of transferring both plants and information between botanical gardens. This system continues today although the possibility of genetic piracy and the transmission of invasive species have received greater attention in recent times. The International Association of Botanic Gardens was formed in 1954 as a worldwide organisation affiliated to the International Union of Biological Sciences. More recently coordination has also been provided by Botanic Gardens Conservation International (BGCI) which has the mission To mobilise botanic gardens and engage partners in securing plant diversity for the well-being of people and the planet. BGCI has over 700 members- mostly botanic gardens- in 118 countries and strongly supports the Global strategy for plant conservation by producing a range resources and publications, and by organizing international conferences and conservation programs. Communication also happens regionally. In the United States there is the American Public Gardens Association and in Australasia there is the Botanic Gardens of Australia and New Zealand (BGANZ). 2.4 Role and Function Botanic gardens have had a changing role throughout history, beginning often as medicinal gardens for the study and cultivation of plants with healing properties and going through many phases including of course as pleasure gardens. But the fact that their collections are more or less scientific means they are continually adapting and serving the needs of their societies in evolving ways as new challenges face those societies. In current times, they are becoming key players in both the conservation of plants and in the education of the people who come to see them. They are also starting to play a role in the mitigation of the effects of climate change, and could be absolutely vital to the survival of the planet as they are perfectly placed to help move species around and help ecosystems to adapt to new climates in different regions. 3.0 Plant conservation 3.1 Importance Plants are universally recognized as a vital part of the worlds biological diversity and an essential resource for the planet. In addition to the small number of crop plants used for basic food and fibres, many thousands of wild plants have great economic and cultural importance and potential, providing food, medicine, fuel, clothing and shelter for vast numbers of people throughout the world. Plants also play a key role in maintaining the planets basic environmental balance and ecosystem stability, and provide an important component to the habitats for the worlds animal life. At present we do not have a complete inventory of the plants of the world, but it is estimated that the total number may be in the order of 300,000 species. Many of these species are in danger of extinction, threatened by habitat transformation, over-exploitation, alien invasive species, pollution and climate change. The disappearance of such vital and large amounts of biodiversity poses one of the greatest challenges for the world community: to halt the destruction of the plant diversity that is so essential to meet the present and future needs of humankind. Plant conservation, long the poor relation of the conservation world, has started to come into its own since the rise of conservation biology as a recognized discipline in the 1980s. Plant conservation, and the heritage value of exceptional historic landscapes, was treated with a growing sense of urgency. Specialist gardens were sometimes given a separate or adjoining site, to display native and indigenous plants. 3.2 Off-site plant conservation Off-site conservation is the conservation of plants away from their areas of natural occurrence. The term ex situ is frequently used to describe the off-site conservation. Off-site conservation not only include growing the plants in botanic gardens, the concept extends as well to field gene banks, clonal collections, and germ plasma banks where propagating tissues and seeds are preserved for growing in the future. Off-site conservation can involve a range of plant parts-the whole plant, seed, other tissues, or genetic material in culture. Whole, living plants have particular value for conservation and will continue to be a major concern of off-site conservation. But conserving whole plants is not simple. To capture the range of genetic variation, such collections require large number of plants; these are expensive to establish and maintain. If the plants are annuals, they will require seasonal replication. Outside their natural habitat some plants may require hand pollination and special treatment of fruit and seeds to ensure germination. It is fortunate that improving technology is making storage as seeds, seedlings, rhizomes, tissues in culture, and even DNA an option for many plants. 3.3 Global Strategy for Plant Conservation The entry point for the strategy is plant conservation; other aspects such as sustainable use, benefit-sharing and capacity building are also included. The Strategy provides an innovative framework for actions at global, regional, national and local levels. The strategy is supported by a wide range of organizations and institutions governments, intergovernmental organizations, conservation and research organizations (such as protected-area management boards, botanic gardens, and gene banks), universities, research institutes, nongovernmental organizations and their networks, and the private sector. The most innovative element of the Strategy is the inclusion of 16 outcome-orientated targets, aimed at achieving a series of measurable goals by 2010. 3.3.1 Objectives The ultimate and long-term objective of the Global Strategy for Plant Conservation is to halt the current and continuing loss of plant diversity. The Strategy will provide framework to facilitate harmony between existing initiatives aimed at plant conservation, to identify gaps where new initiatives are required, and to promote mobilization of the necessary resources. The Strategy will be a tool to enhance the ecosystem approach to the conservation and sustainable use of biodiversity and focus on the vital role of plants in the structure and functioning of ecological system and assure provision of the goods and services such systems provide. 4.0 Role of Botanical Gardens in Plant Conservation Botanic gardens have collectively accumulated centuries of resources and expertise that now means they play a key role in plant conservation. Many of these activities contribute to ex situHYPERLINK http://www.bgci.org/ourwork/ex_situ/ conservation, but botanic gardens also play an important role in in situHYPERLINK http://www.bgci.org/ourwork/Ecosystems/ conservation Horticulture and cultivation skills allow us to grow plants that might be lost in nature, which means their plants diversity can be conserved in the gardens, but also allows us to consider restoration and rehabilitation of degraded habitats. Living collections of plants collect species under various groupings, to maintain a living store of genetic diversity that can support many activities in conservation and research. Seed banks and collections of living plants allow species to be safeguarded. Plants must be carefully collected stored to ensure maximum genetic diversity is retained, and much research is required to determine the best way of storing each species. This is the conservation of plant diversity in situ, and botanic gardens are key to this strategys capacity and success.. Research and development into plant taxonomy and genetics, phytochemistry, useful properties, informing selection of plants that can withstand degraded and changing environments (especially important in face of the threats posed by climate change). Education is a strength of botanic gardens that allows them to communicate the importance of conserving plants, reaching out to diverse audiences, and also to communicate how this may be achieved. Linking plants with the well-being of people, and also helping conserve indigenous and local knowledge, to encourage the sustainable use of plant resources for the benefit of all, as part of sustainable development. The conservation of plant diversity is critical for sustainable development and botanic gardens are playing a key role as centres of conservation action. Gardens maintain a wide range of species as living plants, in seed banks and tissue culture; according to estimation of BGCI, there are probably over 80,000 species in cultivation in botanic gardens of the current estimate of 270,000 known plant species in the world. Botanic gardens contain collections of plants for education, scientific purposes and display; they can be: Taxonomically-based collections of a particular family, genus or group of cultivars; Collections of native plants; Plants which share a common geographical or ecological origin such as Mediterranean, desert or alpine; Wild relatives or cultivars of useful species such as medicinal, aromatic or textile plants; Shared habit or life form such as an orchard, arboretum or succulent collection. Botanic gardens also have important conservation collections particularly of rare and threatened plants. According to the IUCN Red List of threatened plants 34,000 taxa are considered globally threatened with extinction. Currently, over 10,000 threatened species, approximately a third, are in botanic garden cultivation. These plants contribute to species recovery programmes and provide long-term backup collections. Botanic gardens undertake research from plant taxonomy, ecology to breeding systems. With their expertise in horticulture, botanic gardens develop propagation and cultivation methods for plants which have never been in cultivation. All these areas are essential for species recovery programmes and reintroduction of plants into the wild, such as developing techniques to reintroduce the Dragon Trees into the wild. A major cause of biodiversity loss is the over-collection of wild plants for horticulture, medicine and food. Bringing plants into cultivation can take the pressure off the wild populations, and also support livelihoods by generating income and promote trade Botanic gardens also manage protected areas within and outside their garden to promote biodiversity. These ecosystems such as forests, bush land, catchment areas, and coastal areas provide essential services from the generation of water, cycling of nutrients and replenishment of soil fertility and prevention of erosion which are vital to the livelihoods of all people. One of the major causes of species decline is invasive alien species which threaten plants, plant communities and ecosystems. Botanic gardens with their skills in identification and horticulture monitor invasive species and work locally and nationally to restore habitats that are important for diversity. Botanic gardens work with their local communities and visitors on education and environmental conservation programmes which promote environmental awareness and sustainable living. Globally, botanic gardens receive more than 200 million visitors a year. Further, botanic gardens are key institutions working with their governments and other organisations on key policies, national biodiversity strategies and action plans. 5.0 Botanic Garden in Malaysia Rimba Ilmu 5.1 Introduction Rimba Ilmu is a tropical botanical garden, set up in the University of Malaya campus in Kuala Lumpur, Malaysia. It is modelled after a rain forest garden concept rather than a formal flower garden. It emphasises the flora of the Malaysian and Indonesian region. Together with the living collections of over 1,600 species, the Rimba Ilmu also houses the University of Malaya herbarium (acronym KLU) and has its own Environmental Education Programme. The Rimba Ilmu is a member of the Botanic Gardens Conservation International (BGCI) and the South East Asia Botanic Gardens Network. Rimba Ilmu means The Forest of Knowledge in the Malay language. The garden, established in 1974, occupies an area of 80 hectares. It is partly buffered by old rubber plantings and the living collections, mostly from Malaysia, are one of the most important biological conservatories in Malaysia. There are also plant species from other parts of tropical Asia, the Pacific islands, Australia, South America, Africa and Madagascar. Rimba Ilmus mission is to generate and promote awareness and knowledge of tropical plant life and its environment, ecology and conservation through the development and management of facilities and activities appropriate to its function in a university located within Malaysias most developed and populated landscape. The Herbarium (a reference library of preserved plant specimens) is Malaysias largest university collection containing some 63,000 accessions. In the Garden, there are several main show collections, including medicinal plants, palms, and the citrus and citroid collection. The Conservatory of Rare Plants and Orchids, opened in 2000, and the Fernery, with planting establishments made over several years and commissioned in 2003, are accessible only to special group visits and research contacts, and a new bambusetum (living collection of bamboos) was completed at the end of 2003 and generally accessible to the public. There is also a small research collection of bananas. A highlight in the development of the Rimba Ilmu is the establishment of a special arboretum (living collection of trees) beginning in 2001 as the anchor for our Millenium Forest project, which seeks to engage friends and concerned parties in establishing biologically diverse forest plantings in making a new forest withi n the city of Kuala Lumpur. Besides having a general collection of species from a variety of plant families selected for teaching, Rimba Ilmu is also developing various special collections ranging from those of medicinal plants, wild orchids, palms, pandan, tropical fruit trees, gingers, aquatic plants, wild citrus relatives to rare and endangered plants in need of conservation. 5.2 Role in Plant Conservation Rimba Ilmu is an important repository for many types of plants, including conservation collections of rare and endangered plants, and special collections of the useful plants (such as citruses and starch palms) and their wild relatives. In 2001, two other special collections, bamboos (sponsored by the International Plant Genetic Resources Institute) and bananas (anchored by one of the universitys research groups in banana cytology), were also begun. Over 2004-5, with the assistance of DHL and involving their employees, a special collection of Malaysian forest trees has also been established. Outside of the Rimba Ilmu, it may be very difficult to observe so many different species of some groups, and the habitats of some of these plants may have already been altered or damaged. Conservation also involves public awareness, and visitors are first treated to a permanent exhibition on Rain Forests when they start to get familiar with the Garden. 6.0 Conclusion Botanical gardens maintain a wide range of species as living plants, in seed banks and tissue culture. Thus, botanic gardens contain collections of plants for education, scientific purposes and display. In conclusion, the botanical garden play an important role as the ex situ conservation for plant and also in situ conservation site. The conservation of plant diversity is critical for sustainable development and botanic gardens are playing a key role as centres of conservation action.

The Right Of Autonomy :: essays research papers

The Right of Autonomy   Ã‚  Ã‚  Ã‚  Ã‚  Political philosophy is the philosophy of the state. A state is a group of people who have supreme authority within a given territory or over a certain population, according to Wolf. Authority then, is the right to command and the right to be obeyed which is different from power. Power in Wolff's terms, is the â€Å"ability to compel compliance.† Moral autonomy is â€Å"a submission to laws which one has made for oneself.† Wolf believes that there is a problem between authority and autonomy. Autonomy overrides the importance of authority. He also thinks that classical democracy fails to be a solution to this problem.   Ã‚  Ã‚  Ã‚  Ã‚  An autonomous person is not subject to the will of another. This is thought to be the primary obligation of man. In political philosophy, autonomy is a refusal to be ruled, and authority of the state is the right to rule, there is a conflict. If a man fulfills his obligation to autonomy, then he will go against the claim by the state to have authority over him. Wolf states, â€Å"He will deny that he has a duty to obey the laws of the state simply because they are the laws.† This is the major conflict with political authority. Some philosophers believe that a solution to this problem is the concept of democracy.   Ã‚  Ã‚  Ã‚  Ã‚  This argument says that if men rule themselves then they would be both the law givers and followers, combining autonomy with authority. â€Å"His obligation to submit to the laws stems not from the divine right of the monarch, nor from the hereditary authority of a noble class, but from the fact that he himself is the source of the laws which govern him.†   Ã‚  Ã‚  Ã‚  Ã‚  Wolf doesn't think that it fully solves the problem between authority and autonomy. A unanimous direct democracy is the closest to resolving the conflict, yet in only exists in theory. Representative democracy seems to solve the problems of unanimous direct democracy, but it too, has its problems. Its problems lie in the fact that it is incredibly difficult for everyone to be truly represented. If one is not, then their autonomy is sacrificed. Another possible democratic solution is majoritarian democracy. The problem with this comes with those people who are in the minority. The minority voice is limiting their autonomy because they are obeying something that they do not will. Here Wolf again shows democracy fails to solve the problem between authority and

Online Social Network Bring More Benefits Than Harm for Teens Essay

Social networking is even used to prove the legitimacy or credibility of the individual. From entertainment, information to career improvement, social networking has practically changed the way people communicate and interact online. But social networks still have to face certain challenges especially on the users’ end since these challenges could harm users and the social network’s reputation. It is important for users of social network to consider these issues that surround the social network. By remembering these challenges, users will be able to protect themselves from negative repercussions on some issues on social network. Privacy as the Main Concern The number one problem users as well as social network administrators face everyday is security. It can happen in any given time with or without the user online. Attacks on different social networking website are always a possibility because the data protected by social networks are too precious to be ignored by attackers. Viruses, spywares and worms that aim to crawl through security protocols of social networks are constantly threatening social networks. Considerable time and resources are always spent by social networks in order to maintain privacy of their users. A single attack could make every user vulnerable to security related problems such as identity theft. Information Access Access to social networking websites varies. Some website will allow any user to access information of persons even though they are not part of the user’s network while some social network prohibit access to any form of information without confirmation from the profile owner. Problems regarding information access could be completely controlled by user but unauthorized access could still happen especially for those who are just starting to understand the rules of different social networks. Updated Notification Every social network provides real time notification usually through email if there are any changes in the user’s profile. But most notifications are very limited and they are usually on the positive things that happened on the social network. For example, when a request to connect is asked, the user will automatically be notified through email or any messaging system the user prefers. But social networks will never inform the user if someone willingly removes their connection. This is done to avoid confrontations between users which significantly affect the relationship. Misuse of Social Networks Unfortunately, there are those who use social network for scams and other illegal purposes. There have been reports around the world that social networks are used to spread rumors, lies or degrading messages that could affect the person’s reputation. â€Å"Cyber bullying† or an act of being hostile to another user online has also been observed in some social networks. This type of actions should never be allowed in any social network. Users have to be careful on the veracity of the data they receive and to take actions as soon as possible as soon as something undesirable is found on social networks. Protection for Children Aside from privacy and misuse of social networks, the vulnerability of minors is also a big problem for all social networks. While some social networks are geared towards adults, most social networks are open to everyone – including minors. Unfortunately, minors on social networks could become targets of sexual predators that can cloak their real identity in different social networks. While some legislators have taken steps in preventing these offenders from using social networks these efforts could be easily curtailed especially when the offender is more than familiar with the internet.

Noam chomsky essays

Noam chomsky essays Noam Chomsky asserts that the power elites of society shape public opinion and set the agenda for our society- and that in this way, they maintain their system of control. There are a small number of people that are given permission to use up the Earths resources. The problem is that the people who are not in this small number are led to believe that these issues are not important and so are discouraged from having an opinion. He argues that because of this, that real democracy is subverted and we do not even debate the important issues at hand, such as the depletion of the Earths resources. In my paper, I will discuss why I believe that Chomskys assertion is in fact true. . In many ways Noam Chomskys viewpoint points to factual and relevant information. Large corporations, along with the media control a large part of our daily lives. Each day when we turn on the news, we are getting (in a sense) entertained for 30 minutes. A great deal of important information is diluted for the sake of the viewer. There can be nothing that actually drives them to sit down and think about an issue, for that would depress the viewer and thus lose them as an audience. There is a great lack of real news out in the world today. Shows such as Entertainment Tonight show this phenomenon-where people would rather learn about the glamour and excitement than depleting resources. We as a society are led away from thinking that there even is a problem; and for the people that do believe that there is a problem, we merely label them as overreacting. In order to find the real and important information, one has to dig deep into government files and alternative news stories. It is not that the info is not available; its just that the info that is available is extremely hard to find. This is not done by accident either. Those large corporations hold so much control ove...

An Occurrence at Owl Creek Bridge by Ambrose Bierce Essay Example

An Occurrence at Owl Creek Bridge by Ambrose Bierce Essay Example An Occurrence at Owl Creek Bridge by Ambrose Bierce Paper An Occurrence at Owl Creek Bridge by Ambrose Bierce Paper Ambrose Bierce uses realism to portray the dark reality of the Civil War in his 1890 short story, An Occurrence at Owl Creek Bridge. However, Bierce does not portray the brutality of the Confederates, regarded as the enemies of history. Instead, Bierce makes us sympathize with a Southern slave owner, Peter Farquhar, turning our pre-conceived notions of a just war on its head. Using the positive portrayals of the main characters family, the reader begins to feel for the Southern plantation owner. Even with Farquhar’s support for the Confederacy and slavery, which Bierce does not heavily address, the reader begins to root for him to escape his demise. Through Bierce’s negative representation of the Union, Farquhar himself, and the use of family emphasizes the theme of realism throughout An Occurrence at Owl Creek Bridge. Bierce seems to think that war is a brutal cause with no real reward. â€Å"Many veterans like Bierce wondered why they had fought at all (Hess).† Using his own experience in the Civil War, he portrays war as unnecessary violence through his story An Occurrence at Owl Creek Bridge.The story starts out by showing Peyton Farquhar standing on Owl Creek Bridge and he has a noose around his neck. He is about to be executed for burning down the bridge, which is a crucial supply line for the Union. With this beginning alone, we can see the brutal side of war. A man, who is not dressed like a soldier, but a civilian, is about to be executed. There is no evidence that a trial has occurred that has led to this situation. Instead, it seems like a Union army general has condemned him for death. This thought alone can make one shudder. Not only did he not have a fair trial, Farquhar didn’t have a trial at all. Martial Law, in which the military is in control of the laws and the fun ction of areas such as jail and sentencing, has been thrown upon Farquhar. This is not only prevalent in the Civil War, but in wars thought history.
