The Story of Gilgamesh in Sumerian Versions

Table of Contents Introduction Discussion Conclusion Work Cited Introduction In world literature 1, the story of Gilgamesh is among the oldest narratives around the world. The story was initially an oral tradition story and was later recorded on clay in Mesopotamia. The legendary story comes in different Sumerian versions from around 2700 B.C. The story talks about the powers of Gilgamesh who was the King of Uruk and the influence of other gods in the land.Advertising We will write a custom essay sample on The Story of Gilgamesh in Sumerian Versions specifically for you for only $16.05 $11/page Learn More Later on it was recorded in a Akkadian version and then reserved in King Assurbanipal‘s library. According to the story, Gilgamesh was a super human creature and a powerful king who could destroy and conquer others (Lishtar para.1). This paper seeks to critique the nature and powers of historical gods and their relationship to humanity in the past centuries as depicted by the narrative. Discussion Heroism of the kings is limited. The story describes how Gilgamesh oppressed people and slept with every woman. This made the people plead with other gods to provide security for them. As a result, Enkidu is created to counter Gilgamesh powers. Enkidu is however not as powerful as the superhuman king because he is part man and part animal. The limitation of the king’s powers is further seen when Gilgamesh fails to prevent death of Enkidu. This incident occurred after Enkidu and Gilgamesh collaborated to kill the Bull of Heaven (drought) who wanted to crush Gilgamesh to death (George 2). Drought had been sent by Anu the father of Ishatar who wanted Gilgamesh to marry her. On refusal, Ishtar compelled her father to kill the King of Uruk. But because two thirds of Gilgamesh was a god and the other third human, Enkidu died. The other issue that emerges from the myth is that the gods in Ukur are uncooperative. This can be see n when the council of gods decide to kill Enkidu as a punishment for Gilgamesh’s actions. This exposed the other humans to the exploitive powers of the King of Ukur. This further shows that the people in Babylonia were subjects to the gods and had no voice. Human beings are also depicted as creatures that have no freedom. According to the story, Gilgamesh gods have the power over life and death but Gilgamesh still becomes worried after realizing that she would also die. When the people pleaded with gods to create a god who would match Gilgamesh’s powers, the gods created Enkidu and also brought an end to his life. In the story, Gilgamesh is determined to learn the secrets behind life and death. The story says that Utnapishtim was the only creature who had the power to eternally live. In his search for the secret, he meets Utnapishtim who tells him about the flood story that is also described in Genesis, in the Bible. The floods symbolically represent the end and punish ment for human kind. Utnapishshtim says that they were saved from the floods by other gods and that it would not occur again. However, human beings have to die since they are not immortal.Advertising Looking for essay on literature languages? Let's see if we can help you!

Naturally, drought is known to be catastrophic because it causes human suffering. However, the ‘Bull’ springs from heaven where people believe that there are good things and that it is a beautiful land. The other ironic incident is between King Gilgamesh and Enkidu. Gilgamesh is portrayed as a god and a man whereas Enkidu is illustrated as an animal and a man. This is a clear indicator of the differences in the two divinities who were created to control humanity. Conclusion The floods are symbolically used to show that man is immortal and death is inevitabl e. The narrative describes the birth and death of Babylonian gods’. Gilgamesh is depicted as a remorseless leader who has no responsibility for his people. He is depicted as a womanizer and an oppressor. He forces the city’s inhabitants to build walls for the temple so as gain fame. These are indicators of abuse of power and therefore the need to limit the powers of gods. Work Cited George, Andrew.

Sample Evaluation Essay: Are Medical Ethics the Same Everywhere? There are different standards for medical ethics around the world and in some cases cultural clashes can cause a rift. When people move to America they often keep their cultural practices as a part of who they are, and nowhere was this more prevalent than with the Hmong culture. But this also creates a string of ethical dilemmas for medical practitioners in the West who are legally bound to report certain ethical problems like a parent not following the advice of a doctor after signing to do so. Hmong people often do things in ways unfathomable to Western practitioners because they believe that each condition, its cause, and its potential results, stem from something much different than what western doctors would see. Medicine is seen as a temporary fix among the Hmong, not a permanent thing. This can be an area of ethical concern when a medical condition warrants long term medication such as seizure medication, something parents are not willing to do. In such cases, doctors are legally required to report the parents and have the child taken away even if they know the parents have nothing but the deepest love for their child. Additionally, many Hmong avoid hospitals at all possible costs because they are viewed as charnel houses, where the spirits of dead people linger, not as places of healing like they are viewed by people in the West. This can present additional ethical concerns when people will not seek the medical attention they need or their family needs. One example of this is childbirth. Hmong women who would otherwise not seek medical care, would go to the hospital for delivery incorrectly thinking that if they delivered at home the babies wouldn’t be allowed to be U.S. citizens. They naturally deliver healthy babies most of the time in spite of not receiving any Western prenatal care, due to their culturally nutritious diets, the low rate of smoking, the low rate of drinking, The babies, as a result, are often the right size for birth. There was a high prevalence of new mothers seeking medical attention in the delivery room during the 1980’s and 1990’s but nowhere else. For having such staunch beliefs against much of Western medicine, the love and desire of mothers to ensure the very best of chances for the child overruled any cultural apprehensions in this regard and resulted in mothers bearing their babies in a place they would otherwise have avoided just to give them the citizenship. This is truly an inspir ing perspective if one takes the time to think about it. A great insight into the power of strong cultural values juxtaposed against maternal instincts. The Hmong taught a lot of lessons to the Western culture, many of which are exposed in comparison to medical ethics for Hmong and for Americans. There is a serious problem with the high prevalence of antibiotic use in people and animals, as well as the advertisements for medications on television which inevitably encourage people to incorrectly believe they have symptoms and need medication. What is particularly bothersome though is the idea that Western medicine is always right even though it often treats only the symptoms individually and not the illness, something which results in people taking medication after medication to then treat subsequent symptoms that are the direct result of the previous medication. The Hmong embodied this concept wholly with their disregard to regular medication and the use of only those medicines which were needed. Another aspect of the culture which struck me was how the Hmong people, even those Christian converts, never gave up on their roots no matt er what, always seeking out the traditional medications in tandem with Western medication. Some Hmong patients will explain what treatment they thought would be best and remained optimistic about a particular condition. Many are adamant about Hmong healing and will not follow directions from Western doctors for medications or transfusions, which can represent child abuse and a serious ethical dilemma for western doctors responsible for reporting such behaviors. It seems that with such different beliefs, the treatment of symptoms by the Western medicine will continually conflict with treatment of the entire condition or cause as Eastern medicine generally seeks to do in practice.

Role of Healthcare Information System in Quality Service Provision Essay

Role of Healthcare Information System in Quality Service Provision - Essay Example Quality assurance makes reference to the act of putting in place in all necessary measures to ensure the end product of service successfully achieves its intended purpose. Basically, both the IT and healthcare sectors have set of measures in place to ensure quality standards are observed. Unlike the IT industry though, the presentation and behavior of staff directly represents the quality of service within a healthcare setting. On the contrary, quality assurance in IT is primarily pegged on products usability as well as service provision. Additionally, in healthcare settings, quality is a measure of service while in IT industry it is a measure of product efficiency (Joshi 460). Both however offer products/quality which directly impacts on health and any in appropriate measures could cost human life, or amount to medical malpractice. All players strive to ensure that they not only meet the minimum quality service thresholds or even surpass the same. Both healthcare and IT sectors have an ethical obligation to ensure that quality services/products are availed to patients and clients respectively. However, approach to quality assurance as well as assessable quality dimensions largely differ. While in the health sector quality is defined with regard of care standards and procedures including the technical standard of providers and patients expectation, IT industry defines quality with respect to ability of the product to make healthcare provision much easier and readily available. In essence it focuses on minimizing constraints to healthcare access. It is important to note that these definitions give a shallow but broad illustration of the variations in quality perception between the two sectors. What is however evident is the fact that both sectors view quality assurance as a standard ethical procedure which must be attained at all costs. In general, quality assurance may therefore be said as involving all arrangements and activities which safeguard, maintain and facilitate quality healthcare provisions. It involves measurement of quality, identifying deficiencies, undertaking improvements and evaluating whether such improvements are successful.

I will be highlighting 5 of the most key moments in the history of social media. In my opinion, the first one is obviously the development of e-mail. E-mail is probably the first form of digital message. The next one is development of Genie, which was an online forum that led the foundation of social media. I believe the third milestone was a major shift in terms of development (Freeman, 2010). It came in the form of world’s first social platform where users actually got the opportunity to get in touch with their loved ones. The website was known to as classmates.com. The emergence of Friendster, improved and modern social media platform is the next big thing to have happened. The craze was such that within the first month of its launch, around 3 million people joined in. The last major breakthrough came in the form of modern day n etworking platforms such as Facebook, Twitter, and Pinterest. These networks support online transfer of various types of file and has actually taken communication to the next level. The journey of social media has been an eventful one and it is expected that with a similar rate of development, soon human being will experience a new world through the eyes of social networking platforms. Properties of social media Social media is referred to as a virtual network or community where users gather to communicate among themselves and at the same time create and exchange information about the various topics. Therefore from the above findings I can conclude that social media acts as a mediator between the users. Some of the key properties of social media are quality, reach, frequency, accessibility, usability, immediacy, and permanence. I believe these aforementioned properties create disparities among the different social media forms and are the reason that leads to various types of social media (Kietzmann, Hermkens, McCarthy & Silvestre, 2011). For example, due to differences in the features we come across two terms, namely social media and industrial media. The major difference between social and industrial media is that industrial media is more expensive. It includes television, newspapers and films. In my opinion, it is important to distinguish different forms of media because without distinction new forms will never emerge and can even act as a hindrance. In the context of the difference between the new forms of media with rational forms is its ability to go viral. Due to the presence of a million of registered users a small issue can go viral through social media. Types of social media As seen above, social media has various features that allow users to accomplish crucial tasks. However, when a discussion about social media is going on, it is a necessity to underline the different types of social media present in the virtual world. From my personal experience as well as consultation of the textbooks, I have found there are 6 different types of social media namely collaborative projects, blogs and micro-blogs, content communities, social networking sites, virtual game worlds, and virtual social worlds (Gillgian, 2011). According to me, all of the aforementioned types of social media has their own significance and can be described as unique,

Chemistry of Essential Oils

How essential oils are analysed 5. Discussion 6. Conclusion 7. Bibliography 1. Introduction Essential oils are used as alternative medical treatments, fragrances for perfumes and also as flavours in food and beverages (Djilani Dicko, 2012). They are made up of fragranced mixtures that are found in different parts of plants such as the seeds, stems or flowers. (doTERRA, 2014). In this essay the following topics of essential oils will be discussed; the chemical structure, how they are extracted from plants and how to determine their components through analysis. 2. Basic Chemical Structure Essential oils are extracted from plants as the compounds that make up essential oils are created naturally by chemical reactions that occur in different plants. Essential oils are released when oils are chemically extracted from the herb or when the herb is compressed (EBSCO, 2014).There are two groups of chemicals that are made from nature; they are classified into primary and secondary metabolites. Primary metabolites can be divided further into carbohydrates, lipids, nucleic acids and proteins. Secondary metabolites are divided into alkaloids, polyketides, shikimates and terponiods (Baser Buchbauer, 2010). The secondary metabolism of a plant is responsible for their scent and also plays a role in the defence system of the plant protecting it from pests Essential oils are made up of hydrocarbons and their derivatives oxygentated compounds that are created from plants secondary metabolism (Chamorro et al., 2012). As it can be seen in Figure 1 in the biosysthesis of secondary metabolites, water and carbon dioxide are converted to glucose through photosynthesis. Phosphoenolpyrutave is a main element in the shikimate group of natural products. Decarboxylation of phosphoenolpyrutave produces acetate which is esterified with coenzyme-A to produce acetyl CoA. Acetyl CoA is a starting point for Mevalonic Acid, which is the starting compound for terpenoids. Figure 1 shows the chemical structure of the biosynthesis of secondary metabolites. (Baser Buchbauer, 2010). Figure 1: Biosythesis of secondary metabolites (Baser Buchbauer, 2010). Essential oils molecules are prepared mainly from carbon, hydrogen, and oxygen (essentials, 2014). Essential oils can be divided into two groups hydrocarbons and their derived oxygenated compounds (Martin, 2014). The hydrocarbon group is divided into monoterpenes and sesquiterpenes. Hydrocarbon chains are kept together by carbon atoms that are linked together. At different points in the chains atoms are attached to make up alternative oils (essentials, 2014). The oxygenated compounds can be broken down into smaller compounds such as Phenols, Alcohols, Aldehydes, Ketones, Esters, Lactones, Coumarins, Ethers and Oxides (EsotericOils, 2014). 2.1 Hydrocarbons Terpenes are made up of isoprene units. Isoprenes are five-carbon molecules. Isoprenes are assembled in different formations to make up terpenes (Cyberlipid, 2014). Terpenes are a group of molecules that is based on a number of isoprene units in a head to tail fashion. Figure 2 : Isopene Unit (Cyberlipid, 2014) Modified terpenes (terpenoids) are where methyl groups have been moved or removed or oxygen atoms added to the structure. Terpenes are easily decomposable under different effects such as air light and moisture which can cause spoilage of the oil. Terpenes have a narrow boiling range, making them difficult to purify. (Parry, 1922). Monoterpenes and sesquiterpenes are the main components of essential oils as they are adequately volatile (Cyberlipid, 2014), (Baser Buchbauer, 2010). Monoterpenes Monoterpenes have 2 isoprenes units linked together. Monoterpenes are very volatile due to the molecular structure (Chamorro et al., 2012). Monoterpenes increase the therapeutic functions of other components in the oil and stop the collection of toxins (Martin, 2014). An example of an essential oil that is a monoterpene is menthol which is a cyclic monoterpene. Menthol has cooling properties and has a unique scent of the oil residue that is extracted from it (Kamatoua et al., 2013). There is a difference in the content of methone and menthol detected, as the plant mature there is a higher content of menthol and menthyl acetate content (Baser Buchbauer, 2010). Figure 3: Steoreoisomers of menthol (-) –menthol is the most commonly used synthetic and natural form. Menthol has microbial properties but is not a principal compound in essential oils as it is only a component in of a restricted number of aromatic plants (Kamatoua et al., 2013). Sesquiterpenes Sesquiterpenes have 3 isoprene units linked together. They are common in essential oils and are less volatile than monterpenes so they blend well with volatile oils (Martin, 2014). An example of a sestquiterpene is Zingiberene that is used in the oil. It is acquired by fractional distillation under reduced pressure (Parry, 1922). Figure 4: Structure of Zingiberene (Chemistry, 2014). 2.2 Oxygenated Compounds Oxgenated compounds or terpenoids are derivates of terpenes. They have a stronger aroma and are normally more stable as they do not oxidise as easily under different conditions (Fresholi, 2014). Some examples of oxygentated compounds are alcohol, ketones and esters. Alcohols can further be divided into monoterpene alcohol and sesquiterpene alcohols (EsotericOils, 2014). Alcohols are found in in their free state and in the form of esters in essential oils. Methyl alcohols which are soluble in water which are main components in essential oils are removed during the distillation process so they are not actually found in the essential oil but can be found in the distilled water. But when in ester form methyl alcohols can be found in essential oils such as winter green. (Parry, 1922). Alcohols are beneficial components that have antimicrobial and antiseptic properties. Esters are naturally occurring in plants. Esters such as terpineol attribute to the aroma in essential oils (Pharmacognosy, 2012). They also have calming and sedative properties (Oils, 2007). Linalyl acetate is a naturally occurring ester that is found herbs and flowers. It is used to make Lavender oil (Hermitageoils, 2014).Ketones have skin healing properties and also helps break down fats (Oils, 2007). Verbenone is an example of a natural ketone that is extracted from plants. It is an ingredient in the oil Rosemary Other examples of oxygenated compounds are aldehydes that have anti-inflammatory and anti-infectious agents such as geraniol found in Rose Geranium. Oxides that have anti-inflammatory properties such as eucalyptole are found in Eucalyptus. Phenols have anti-pathogenic properties (Oils, 2007). Thymol is an example of a phenol, it is a compound of thyme and ajowan seed oil (Parry, 1922) and ethers help regulate hormones and the central nervous system such as chavicol found in basil (Oils, 2007). 3. Extraction Methods There are different extraction methods that are used for the extraction of components for essential oils. There are two main types of extraction methods these are distillation and expression. Solvent extraction and CO2 extracts are also other techniques that can be used for the release of essential oils from plants. Different distillation methods that are used are steam distillation, water distillation and steam and water distillation. For distillation process the material from which the material is being extracted is placed on a grid in the still, the steam or/and water depending on which method is being used breaks through the plant material and removes the volatile compounds in it. The volatile compounds rise up into the condenser which cools the vapour into liquid form. This oil liquid will be form a separate layer with water and can be drawn off separately from the water (NAHA, 2014). Expression of essential oils is done through a technique known as ecuelle a piquer. This technique involves placing the rind of a fruit in a container with spikes that puncture the peel while it is being rotated. This technique allows the essential oils that are contained in the fruit to be released when it is punctured. Centrifugal force can then be used to separate the fruit juice from the essential oils (NAHA, 2014). Solvent extraction is used when the plants are too fragile to go through the distillation process. In solvent extraction the odoriferous lipophilic is extracted from the plant along with other tissues in the plant. This causes a thick solution to be extracted that contains waxes, fats and other odoriferous material. This solution is then mixed with alcohol which extracts the aromatic compounds (NAHA, 2014). Hypercritical carbon dioxide (CO2) extraction involves putting C02 under pressure to turn it into a liquid from a gas. This liquid is then used as an inert liquid solvent which can extract aromatic compounds from the plant by diffusing through it. C02 can contain some elements that are not found in the corresponding essential oils. During extraction methods some main considerations must be addressed such as the cost, pesticide residue on the plants and also the safety and therapeutic benefits of the essential oil being produced. These considerations help decide which extraction method is most beneficial (NAHA, 2014). 4. How essential oils are analysed Terpenes are structurally varied therefore the methods used for analyses have to account for a great number of molecular compounds (Baser Buchbauer, 2010). With essential oils there are cheaper versions available on the market. Sensory tests are preformed first to help determine if the oil is poor quality. The clarity, colour, odour and viscosity are looked at to determine the quality. When these sensory tests are completed, physical parameters are measured through refractive index, optical rotation and their specific gravity (Lyth, 2014). Chromatography techniques are then used in the separation and identification of compounds (Baser Buchbauer, 2010).Gas chromatography/Mass Spectrometry is widely used in the separation and identification of compounds in essential oils. In gas chromatography the identification and quantification of the different chemical compounds in essential oils can be detected. Each individual compound can be identified by the retention time of the peaks. The data collected can then be compared against standards to determine the purity. (Lyth, 2014).One of the main objectives in separation is the resolution of the compound with a short retention time. To achieve this, the appropriate parameters must be provided. Chiral stationary phases allow for the separation of compounds with optical isomerism. When identifying essential oils in gas chromatography the temperature must be changed as essential oils contain votaile compounds and less volatile compounds. The temperature must start off low and then be raised every minute until 200C to obtain elution of heavy terpenoids. This allows for shorter elution times, separate and narrow peaks (Baser Buchbauer, 2010) 5. Discussion The chemistry of essential oils is important as they have such diverse effects. The different structures of the compounds is what causes the effects of the essential oil (EBSCO, 2014).It also depends on what part of the plant is being used and also the development stage of the plant. There are also changes in the amount of oil yield and the different compounds that are observed between the process of the bud of a flower forming and full flowering (Baser Buchbauer, 2010). But a plant’s compounds can have different effects depending on the country of origin, the type of soil it was grown in and also the climate conditions of where it was grown. These factors can all effect natural variations in the essential oils that are extracted from the plant (Lyth, 2014). Even though essential oils are known for their healing properties it is difficult to prove that they work because of the unique aroma of essential oils it is also difficult to have a control group. A lot of published studies on essential oil fail to reach accurate and reliable scientific standards (EBSCO, 2014) 6. Conclusion Essential oils are used in a variety of industries, but it is important to know the chemistry behind the process of producing them. This helps produce high quality and pure products that will produce better results. The extraction of them from the plant and also where the plant was growing and the conditions that it grew in are important factors when analysing the product for quality and purity. 7.
