The Scope Of Customary International Law - 1681 Words

Within the scope of customary international law, there are some varying norms that the international law community must deal with, which are broken down into three different categories from most important to least important: 1) norms in which the international community allows no derogation, these are known as peremptory norms or jus cogens, 2) norms that might allow for derogation, and 3) norms that aren’t binding but some might argue should be. To classify these customary norms scholars use both state practice and opinio juris. In order to determine state practice the states may look towards each other and how they react in similar scenarios. One debate surrounding this area is determining how many states need to sign off on an action to determine that sufficient state practice is occurring. Two sides of the argument are the actual number states versus the regionalization of the states. Opinio juris is defined as a state engaging in a certain activity because they believe they are under legal obligation to act. The idea of peremptory norms is older than modern international law itself (113). The idea of peremptory norms stems from the belief that certain actions are so heinous that derogation is not allowed. The Vienna Convention on the Law of Treaties shows the importance of peremptory norms in both Article 53 and 64. Article 53 states that a treaty is void if, at the time of its conclusion, it conflicts with a peremptory norm. Article 64 explains that treaties,Show MoreRelatedV Royal Dutch Petroleum Co.

Practice Experience, Decision-Making and Professional Authority Free Essays

string(70) " offered to attend the HOC centre with her to advocate on her behalf\." Abstract The essay describes a case study from the author’s experience working for a domestic violence agency. The case involves a French woman whose partner is violent towards her. The theoretical background is set out, and theory applied to this particular situation. We will write a custom essay sample on Practice Experience, Decision-Making and Professional Authority or any similar topic only for you Order Now Additionally, the legal framework is discussed. The need to apply professional decision-making skills and communication skills is brought out. 1. Introduction This essay discusses a case study drawn from my experience working for a domestic violence agency in inner London during 2012. I focus upon an incident where I worked alone with a service user suffering domestic violence. There is no legal definition of domestic violence (DV). However, the government describes DV as â€Å"any incident of threatening behaviour, violence or abuse (psychological, physical, sexual, financial or emotional) between adults who are or have been in a relationship together or between family members, regardless of gender and sexuality† (Home Office 2012 [online]). Most reported DV cases are directed by men towards women. DV also occurs in same sex relationships and in a relatively small number of cases, by women against men. The case study is described, and my experiences of decision-making and how I exercised professional authority brought out.I explore the theories surrounding the areas I look at in the case study, particularly the ways theory links with practice. I also look at the legal policy framework which is relevant to the case study. I also bring out personal skills including communication and look at the role they played. 2. Case Study I started my placement with a domestic violence agency in an inner city London borough in March, 2012. The agency works exclusively with service users fleeing domestic violence.The incident I have chosen for this case study involved lone working with a service user who had approached the organisation that I am on placement with for support regarding domestic violence abuse she was suffering at home. The service user will be referred to as SS in accordance with the Data Protection Act 1989.SS is a French national who had relocated to the United Kingdom with her mother at the age of 14. Her relationship with her mother had broken down because she remained in a relationship with the perpetrator (Perp) at her mother’s disapproval. She had been married to the Perp for three years. They have two children, age 14 months and 2 months, her first child is a girl and the new born baby a boy. The perp started to be controlling after she had their first child. After their second child was born the abuse started happening more frequently. On a particular occasion, the perp grabbed SS, threw her against the wall and hit her several times across the face. She approached my placement agency for support after she was advised by another agency. SS attended as a duty. Therefore, the onus was on me as the duty staff to assess her circumstances and offer appropriate advice and support to safeguard SS and her children. As such, I had a role of responsibility, with the future wellbeing of SS partly in my hands.I prepared for the DV2 assessment in line with the agency’s lone working policy. I signed SS in and informed my peers of the room where the assessment was taking place; I also booked her in the duty book. I made sure the assessment room I choose was available, clean, spacious and comfortable as there was a professional from another agency and her children with her also. I also made sure that SS had a private space to discuss her issues and express her feelings without interruptions from her children. I had provided toys to distract her eldest child whilst the assessment was going on. SS informed me during the assessment that some of the documents that she might need to present at the Homeless options Centre (HOC) were at home, she offered to quickly rush home to pick them up whilst the perpetrator (Perp) was still at work. I advised her that the risk associated with such action might be too great for the children and herself, as the perp might walk in on them. I gave her options to either get a police escort or ask a friend who lives near the house to get such documents for her. By so doing I was able to manage the risk to SS and her children. I used the DV2 assessment form to understand her needs, whilst also working together with SS to respond to her crisis situation. I was able to address behaviours that posed a risk to her and the children, I recognised and acknowledged the risk to SS if she returns to the house alone. She agreed that going back to the family house will put the children and her at risk. The risk was assessed and plans were put in place to manage such risk and minimise the risk of further abuse to her and the children in accordance to the GSCC code of practice and Every Child Matters agenda, 2004. Through the DV2 assessment, I also able to identify the need for safe and comfortable accommodation to manage such identified risk to SS and her children. However, my concern was that she might go back to the abusive relationship if appropriate support was not available. SS would still need to pass the habitual residency test (HBT) as an in EEA national to ascertain her rights to public funds in the United Kingdom because of SS’s nationality (French). If she fails this test (HRT), she might not be eligible for benefits, and the stress of managing with two children without an income might be too much for her to cope with alone. Hence, without adequate support available, she might return to the abusive environment from where she is trying to flee. I wrote a housing letter to the HOC to support her claim for domestic violence and also offered to attend the HOC centre with her to advocate on her behalf. You read "Practice Experience, Decision-Making and Professional Authority" in category "Essay examples" By so doing I was able to mitigate the risk to which SS and the children were exposed. I gave her a voice and also considered t he children’s situation and the statutory support that might be available for them. I searched for local refuges to address her housing need, made a referral to children’s social services, provided food vouchers and made arrangements for them to be accommodated away from the perp’s area of influence. 3. Theoretical Context / Legal Policy and Framework, Application to Case Study This case can be seen in the context of a number of theories relevant to the situation, and also in the context of current legal policy and legal framework. This section will look at these connections, first at the theoretical context and next at the legal situation. 3.1 Theoretical Context and Case Study Application The psychologist Maslow suggested that all human beings have a number of needs which need to be satisfied in order for a person to live at his or her full potential. These needs, he also suggested, form a hierarchy, that is, they are ordered. ‘Lower’ needs are required to be satisfied first, before other needs come into play (Maslow 1943). Physiological needs are the most basic, including things we need to do to survive (eating, sleeping etc.). Next come security needs, that is the need for shelter and access to health services. Once these are satisfied, social needs become relevant. These are the needs for feeling part of a group, affection and similar. These are frequently satisfied by work, friends and family.Higher level needs are the need for esteem, that is, for feeling good about oneself and social recognition, and the need for ‘self-actualisation’, the need for personal growth and fulfilling one’s ability to the full (Zastrow et al 2009). In terms of this model, SS was clearly struggling with needs at the lowest level, physiological and security needs. She was finding it difficult to access funds for her children to eat, and given that the perp. lived in the family home, her housing needs were threatened. SS’s health would also be under threat should she return to the family home. As such, the model predicts that SS would be feeling exceptionally insecure and vulnerable: â€Å"partially met or unmet human needs are associated with increasing vulnerability† (De Chesnay and Anderson 2008, p. 489). Another theoretical model is provided by crisis intervention theory’. This is a particularly useful model as it is directed towards practical action (Coady and Lehman 2007). It is based around the idea that a crisis presents both a challenge (in an extreme form) and an opportunity (Roberts 1995). In other words, a crisis can lead to positive change. One leading developer of the idea was Erkison (1950) CITE) who looked at the role played by crisis in the maturation of typical human beings. Eric Lindemann (1944) developed a systematic model to deal with crisis. A model suggested by Golan (1978) is useful for this case study. He suggested four stages: first, the person suffering the crisis develops a subjective response to the situation. Next, this leads to upset or lack of balance, previous ways of dealing with problems don’t apply. At this stage, though it is chaotic, there is some hope for new approaches. Thirdly, this particular crisis can link to unresolved conflic ts in the person. Finally, the first three stages lead to new opportunities to develop new ways of dealing with potentially damaging situations. It is the role of the professional to help the service user see these new ways of responding (Roberts 1995). In terms of the case study, SS seems to be at a crisis point, and one which led to the development of new ways of dealing with her abusive partner.One incident led to SS presenting to the agency, but this crisis incident was the catalyst for realising that her previous attempts to deal with the situation of violence, through staying with her abusive partner, were not working. Though greatly distressed, particularly by the upheaval she and her children were experiencing, SS learnt new ways of dealing with the situation, primarily removing herself from the family home and asking authorities for support in finding a new home. I personally found psychodynamic theory, which aims to uncover the reasons for domestic abuse in early childhood situations, less useful to this particular case study. The ideas about how rage from childhood is visited upon an adult’s current partner (Sanderson 2008) are, I felt, useful as a background, however psychodynamic theory seems to advocate long-term therapeutic treatments which just aren’t possible or appropriate given the immediate emergency of the situation. However, I did find that ideas like this helped me step back and understand that sometimes people’s actions stem from very deeply rooted issues which are hard to tackle. This has helped me overcome an early frustration with some client’s inability, seemingly, to see what is going on clearly. I felt the more practically focussed therapeutic techniques were more useful. These included person-centred and task-centred approaches.Person-, or client-, centred therapy was developed by Rodgers in the 1940’s. It suggests that the client is at the centre of any counselling process, and that it is the task of the counsellor (or, in this case, the social services professional) to understand how the client sees the world. Without this understanding, it is not possible to help the client move forward. The person-centred approach advocates avoiding lecturing, manipulating, bribing, directing or otherwise trying to change the client’s behaviours from outside. Rather, the need is to empower the client to grow (Vincent 2005). There are a number of techniques which can be used, including empathy, congruence (letting the client see you as you are), and positive regard (Jarvis et al 2002).I found this theory particularly useful, as it made me realise the need to abandon judge ment of SS, and get to know how she saw the situation. The idea of congruence helped me see that I need not present an entirely blank, professional face, but could inject something of my own personality into our meetings. The task-centred approach is time-limited, that is (unlike many psychodynamic therapies) it is carried out over a time period fixed in advance. It is therefore useful in situations like this one where only a limited period of time is available. The idea was developed in the USA, but has become widespread elsewhere. It involves client and professional agreeing together some goals to be reached over a clearly defined period of time. It emerged from a background where social work was hampered by a psycho-analytic perspective on client behaviour, and thus offered a much-needed way to focus upon specifics and deliverables. The approach involves mutual agreement about goals, problems which the service user can see for themselves and which they can work on by themselves between sessions. The focus is upon what the user wants to change (Wilson et al 2008). I found this approach a useful one to combine with a person-centred perspective. I was able to agree with SS things she wanted to change (living with her abusive partner) and we agreed tasks to complete to achieve this overall goal, including contacting other agencies for housing advice. Ideas about risk management and risk assessment were also very useful in this particular case, as there was a risk of harm from the perp. for the client, and perhaps also for social service professionals who became involved. Because perceptions of risk are highly subjective, there is a need to objectify the existing risk(s) as far as possible to try and eliminate as much bias as one can. Normative models of risk â€Å"address how to make the best decision when there are a number of possible options or ways forward† are useful: they allow the assessment of how likely certain outcome are (Messer and Jones 1999, p. 90). As this situation involves young children, structured risk assessment models are useful, as they allow the situation to be assessed in terms of children’s needs as well as the mothers (Harne 2011). Many now advocate shifting away from risk assessment looking at single factors to looking at â€Å"the interaction of factors across individual, social and cul tural domains† (Chalk and King 1998, p. 277) 3.2 Legal and Policy Framework, and Case Study Application There are a number of legal and policy documents which are also relevant to the case study. The Domestic Violence, Crime and Victims Act 2004 was designed to extend the protection available to vulnerable adults and children, and included a new offence of ‘causing or allowing the death of a child or vulnerable adult’, designed to address cases where two partners failed to admit responsibility for child injury. It also made common assault an arrestable offence, added new powers to fine offenders, and changed non-molestation orders to allow non-compliance to attract prison sentences of up to 5 years. The circumstances under which a case can be heard without a jury are also extended (Guardian 2009). This Act offers a range of additional protections for the victims of domestic violence, in terms of criminal proceedings which might be brought against the perpetrator. For the case study above, SS has not reached the point of deciding to press charges against her partner. My f irst concern is to make sure she has secure accommodation and is safe from further abuse. However, in time, she will consider the possibility of legal action against her partner, and I feel the Act allows extra protection for her which might make her more likely to consider it. As the situation is a complex one, a number of other legal frameworks and policies are relevant. Because SS is unable to return to the family home because of risk of further abuse, the Housing Act 1996 is also relevant. Under the act SS is likely to be eligible to be housed by her local authority, as it places a duty on authorities to advise and possibly house people if they are under threat of becoming homeless, have a priority need, are not intentionally homeless and have a local connection to the area (amongst other criteria) (Housing Act 1996). These things apply in SS’s case. Additionally, the code of guidance for local authorities in regards to homelessness was published in 2008. This spells out the duty of local authorities more clearly, and also suggests a need for social services and housing bodies to work together more closely (Department for Education and Skills 2008). However, because SS is originally from France, there is a question regarding her access to public funds. In order to benefit from the help she needs, she needs to pass the Habitual Residence Test. The Habitual Residence test was developed as a way to ensure that only those people with a connection to the UK can claim benefit here. The concept is not legally defined, and in practice a number of markers are involved in decision making, including length of stay, continuity of stay, the person’s intentions and the nature of their residence (Currie 2008). It is claimed that the concept of habitual residence is more stringent than the concept of ordinary residence found elsewhere in law. It is likely that the presence of the children, SS’s history and her desire to remain in the country will all count in her favour, however it represents another obstacle to the security of her future (Harris 2000).Additionally, the 2002 Nationality, Asylum and Immigration Act restricts entry and leave to stay in the UK. Finally, I was also influenced by the Data Protection Act 1989, which protects the confidentiality of client data, for example dictating that I refer to clients only by initials or pseudonyms, and by the GSCC Code of Practice. The latter is particularly important, as it provides the framework within which social workers should operate in the UK. Part of the guidelines are concerned with the need to protect and promote the interests of the client, establish their trust and confidence, and promote their independence. These aspects are particularly interesting in the light of the theory discussed above, as they are broadly in line with the aims of client-centred and task-centred approaches. 5. Conclusion This essay has addressed a case study taken from my experience working with victims of domestic violence. I have tried to show how theory is relevant to the situation I describe, and how legal issues are also relevant. It was necessary for me to make a number of decisions throughout the experience I describe, however perhaps the most important skill I brought to play was that of communication. I had to communicate not only with other agency staff about this case, but also with multiple outside agencies (housing, benefits and similar) and, perhaps most importantly, with the client. The section on theory above has pointed out some of the therapeutic perspectives which were useful, and the client-centred approach, with its emphasis upon empathy and understanding, have been particularly helpful to me in the communication process. I have also used feedback from other staff members and reflective feedback processes to understand the impact of how I communicate to clients, and use this fe edback and reflection to make improvements to my skill set. SS’s case history, like all cases of domestic violence I have come across, is complex and requires an equally complex set of skills on the part of the social worker to produce the best possible outcomes. 6.

Oedipus And Antigone Essay Example For Students

Oedipus And Antigone Essay Oedipus and AntigoneSophocles plays Oedipus and Antigone have many parallel themes and conflicts. Certain characters and events are mirrored and go through similar sequences in both plays. One conflict that is prevalent in both plays is the idea of loyalty. In Oedipus, many are loyal to Oedipus, including the city of Thebes itself. In Antigone, there is much strife in the relationships as well, and the idea of loyalty arises. In the play Antigone, there are many situations in which loyalty is involved, and in some, conflicts arise. The first example of this is the relationship between Haimon and his father Creon. This unusual relationship between them is incredibly superficial in that Creon is only proud of him because he is kissing up and says what his father wants to hear. It is blatantly obvious during their conversation where Haimon states; I am your son father. You are my guide. You make things clear for me, and I obey you. No marriage means more to me than you continuing wisdom. This statement is basically what Creon expects to hear out of his son. His reply of, Good. That is the way to behave: subordinate everything else, my son, to your fathers will. Creon is used to having people do everything he wants them to do. The second example is the relationship between Antigone and her dead brother Polyneices. She is incredibly loyal to him and is willing to risk her life in order to preserve his honor as a warrior and bury her against Creons order. It is evident in her statement of, But I will bury him; and if I must die, I say that this crime is holy: I shall die down with him in death, and I shall be as dear to him as he to me. She will do whatever it takes, even if it is death, to bury her violated brother. The third example is the relationship between Haimon and Antigone. Although Haimon was loyal to his father, he later broke away from his grasp and went to the aid of his fiancee Antigone. He felt that he betrayed her by siding with his father when he was obviously wrong and being stubborn. He signifies his loyalty to Antigone with the statement of, But her death will cause another. He will openly defy his father in order to stand by her side. There are numerous examples of loyalty in the play Antigone. There are also many examples of loyalty in the play Oedipus. The first example is the loyalty of the whole entire city of Thebes to Oedipus. He came and saved them from the great Sphinx and became their generous and just ruler. Once it was discovered that he murdered Creon, he was to live up to his word and wanted to be driven from the town. The town, however, did not shun him, and acknowledged him as a great ruler that had brought upon his own demise. The second example is the loyalty of the shepherd that Oedipus was entrusted to, to king Laios. He was relied upon no to reveal the secret of the attempted extermination of Oedipus. That guard then became one of king Laioss most trusted officers and was with him during the attack of Oedipus on him in which he was slain. The third example is that of the loyalty of most people to the Oracle, in that they all have faith and believe in the Oracles prophecies. They are willing to believe in the prophets, such as Tierces because they are spe akers and messengers for what the Oracle says. After Oedipus was born, and his fate was known, Laiou and Iocaste immediately took action. They believed what the Oracle said, but naively tried to change their sons fate by attempting to eradicate him. Of course, as the story goes, their plan was thwarted by the kind heart of the guard and thus the cycle began. There are many examples of loyalty in the play of Oedipus. .uf10dc0c8160104f085b2ab9d9e7fe403 , .uf10dc0c8160104f085b2ab9d9e7fe403 .postImageUrl , .uf10dc0c8160104f085b2ab9d9e7fe403 .centered-text-area { min-height: 80px; position: relative; } .uf10dc0c8160104f085b2ab9d9e7fe403 , .uf10dc0c8160104f085b2ab9d9e7fe403:hover , .uf10dc0c8160104f085b2ab9d9e7fe403:visited , .uf10dc0c8160104f085b2ab9d9e7fe403:active { border:0!important; } .uf10dc0c8160104f085b2ab9d9e7fe403 .clearfix:after { content: ""; display: table; clear: both; } .uf10dc0c8160104f085b2ab9d9e7fe403 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .uf10dc0c8160104f085b2ab9d9e7fe403:active , .uf10dc0c8160104f085b2ab9d9e7fe403:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uf10dc0c8160104f085b2ab9d9e7fe403 .centered-text-area { width: 100%; position: relative ; } .uf10dc0c8160104f085b2ab9d9e7fe403 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uf10dc0c8160104f085b2ab9d9e7fe403 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uf10dc0c8160104f085b2ab9d9e7fe403 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .uf10dc0c8160104f085b2ab9d9e7fe403:hover .ctaButton { background-color: #34495E!important; } .uf10dc0c8160104f085b2ab9d9e7fe403 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uf10dc0c8160104f085b2ab9d9e7fe403 .uf10dc0c8160104f085b2ab9d9e7fe403-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uf10dc0c8160104f085b2ab9d9e7fe403:after { content: ""; display: block; clear: both; } READ: Arab - Israeli Wars EssayWhen someone is loyal to a person, a group, or an idea, it is their intent to do whatever is necessary to support them or it. This principle has been evident in the plays of Oedipus and Antigone. They are similar in many respects, having ideas rolled into the plots such as loyalty, by Sophocles. Whether it is the loyalty of the city of Thebes to Oedipus, or the early brown-nosing relationship between Haimon and Creon, the idea of fealty is the same for all of them.

Extraction of Caffeine from Tea Leaves Essay Example

Extraction of Caffeine from Tea Leaves Essay Extraction of Caffeine from Tealeaves Perez, Albert Solomon K. *; Quiambao, Marie Angela C;. Pascua, Hanna Harriette R. ; Patricio, Maria Roxanne DC. ; 2-Chemistry, Department of Chemistry, College of Science University of Santo Tomas Espana St. , 1015, Manila Abstract Caffeine is soluble in both water and organic solvents, solid-liquid extraction and liquid-liquid extraction were used in the experimentation process. Caffeine was extracted using hot water, however, due to its medium polarity; it was further separated from water soluble compounds using a polar non-protic solvent, dichloromethane (CH2Cl2). Sublimation was then used for the purification of the targeted compound. Based from the data collected, 5. 758g of tea leaves contains 3. 96% caffeine. After the purification process, 0. 2279g of caffeine was obtained from 0. 4948g crude extract with 46. 06% yield. Melting point determination was used to characterize the caffeine yielded. However, the melting point range of the caffeine collected (190Â °C -215 Â °C) was lower than the melting point of the accepted value (238 Â °C) which may be due to experimental errors committed in the extraction and washing process. Introduction Tea has been consumed as a beverage for almost 2,000 years starting in China. It is the most widely consumed beverage after water [1]. Their active participation in trade resulted in its introduction to Europe. The active component in tea is caffeine (C8H10N4O2). Caffeine belongs to an extensive class of compounds known as the alkaloids. Alkaloids are a diverse group of compounds that are found primarily in plants and contain basic nitrogen atom(s). The basic nature of these compounds makes them exists mostly as salts.

Aside from being a mild stimulant, caffeine is one of the most promising organic compounds in medicine, in a study by Miura, T. et al. , green tea extracts showed lowering in blood pressure of a mice with diabetes type 2 and thus a plausible treatment for diabetes[2]. However, caffeine may be associated with serious ventricular arrhythmias in susceptible people. Caffeine may increase beat-to-beat heart rate variability and also QT interval variability during rapid eye movement sleep[3]. Caffeine cannot be obtained directly; every pot of coffee or cup of tea involves solid/liquid extraction, the extraction of organic compounds from solid ground beans or leaves using hot water as the liquid. The lower molecular weight polar molecules such as caffeine dissolve in the hot water and are removed from the high molecular weight water-insoluble cellulose, protein, and lipid materials. Over 200compounds, some in only trace quantities are extracted from the solid into a cup of coffee or tea. Figure 1 shows the chemical structure of caffeine. [pic] Figure1. Caffeine While solid-liquid extraction is the most common technique used to brew beverages and isolate natural products, liquid/liquid extraction is a very common method used in the organic laboratory. Organic reactions often yield a number of by-products, some inorganic, some organic. Also, since they do not go to 100% completion, some starting material is also often present at the end of an organic reaction. Liquid-liquid extraction is often used as the initial step in the work-up of a reaction, before final purification of the product by recrystallization, distillation or sublimation. Varying extracts from various plants have been used as teas, potions, medicines and poisons. However, these extracts can contain a mixture of many different chemicals, often only one or few are responsible for the activity of the extract. The objective of this experiment is to isolate, purify and characterize caffeine from tea leaves. Moreover, to calculate the percent yield of caffeine. Results and Discussion Extraction of caffeine from tea leaves through solid-liquid extraction using water bath would cause the tea leaves to swell and release caffeine and other compounds such as tannins. To further separate caffeine from other soluble compounds, an organic solvent, Dichloromethane (CH2Cl2) was used. Dichloromethane (CH2Cl2) selectively extract caffeine from the tea extract by separating it from the other organic compounds and leaving them suspended in water. Table1. Relative Weights of Products Yield of Products | |Brand of tea leaves |Nature’s Pride | | | | |Extraction | |Weight of beaker |28. 6880g | |Weight of beaker |34. 4460g | |+ tea leaves | | |Weight of tea leaves |5. 58g | |Weight of evaporating dish |115. 7196g | |Weight of evaporating dish |116. 2144g | |+ crude caffeine | | |Weight of crude caffeine |0. 4948g | | | | |Purification | |Weight of empty vial |32. 2127g | |Weight of empty vial |32. 406g | |+ caffeine crystal | | |Weight of caffeine c rystal |0. 2279 | Extraction uses the solubility differences of these molecules to selectively draw the product into the organic layer. Liquid-liquid extractions using 20mL dichloromethane was done three times to ensure the highest percentage of caffeine separation. All portions of dichloromethane was mixed and was washed with 20mL 6M NaOH in the separatory funnel, to remove acidic content from the solution that may have remained after the extraction with dichloromethane. The ‘washed’ dichloromethane solution was filtered through a filter paper containing anhydrous Na2SO4 to further dehydrate the solution, hydrating the Na2SO4 into its hydrated form Na2SO4Â ·H2O. Table 1 shows the different weights of the sample obtained through extraction and purification before its characterization. Crude caffeine, about 0. 4948g was obtained through recrystallization, and was purified. Purification was facilitated by sublimation with an air bath to gather the pure crystalline caffeine. The crystalline caffeine was found to be 0. 276g in weight. The percent recovery and percent caffeine can now be computed through: % recovery = [pic] % caffeine = [pic] % recovery = [pic]% caffeine = [pic] % recovery =46. 06%% caffeine = 3. 96% To characterize the sample, determination of the melting point was used. Table 2 summarizes the results of melting point determination of the sample and standard caffeine subjected to an oil bath consisting of cooking oil at 150 degrees celsius. Table2. Melting Point Determination |Melting Points (? C) | |Sample caffeine |Standard caffeine | | | | |T1 | |190 degrees |225 degrees | | | | |T2 | |215 degrees |228 degrees | | | | |190-215 degrees |225-228 degrees | The accepted value for the melting point of caffeine is 238? C [4]. The experimentally determined temperature for the sample caffeine was very low in comparison to the standard and the accepted value. The standard caffeine had close values and a smaller melting point range. Errors could lie in between the melting process, as the standard underwent some thermal decomposition evident in the slight change in the color of the sample while melting. The temperature obtained explicitly shows the presence of impurities on the sample caffeine, as the presence of non-volatile solutes owers the temperature and increases the melting point range of a sample. Imprecise reading and observations could have been one of the reasons for the slightly lower melting point temperature readings for the standard caffeine. Experimental For the extraction of caffeine, commercialized tea bags (3) were used as a source of tea leaves. Tea leaves were removed from the bags and were weighed. After weighing the tealeaves, solid-liquid extraction was done using 100-mL water and was allowed to boil for 5 minutes. The sides of the flask were then cooled in a running tap water for 2 minutes. An ice cube was mixed in the tea extract to facilitate cooling to room temperature. The tea extract was transferred in a separatory funnel containing 20-mL of dichloromethane to facilitate liquid-liquid extraction of caffeine. The CH2Cl2 was found to be in the lower layer and was drained into a clean flask. The remaining solution in the separatory funnel was again treated with 20-mL CH2Cl2 twice to further extract the remaining caffeine. All CH2Cl2 fractions were combined. All of the CH2Cl2 was returned to the separatory funnel and that was washed with 20-mL 6M NaOH solution. After washing, The CH2Cl2 layer was drained into a flask through a funnel with a fluted filter paper containing half spatula of anhydrous sodium sulphate to remove the remaining water content. The CH2Cl2 was subjected in a water bath to further concentrate the extract. The crude caffeine was weighed and the numerical value was recorded. For the purification process, the crude caffeine was transferred into a filter tube with a fitted inner test tube which served as the ‘cold finger’ and was placed in a hot air bath. The crude caffeine was allowed to sublime to gather crystalline caffeine at the bottom of cold finger tube. The cold finger was constantly refilled with ice water to facilitate sublimation. The crystalline caffeine was scraped off the cold finger tube and was placed into a vial. For the characterization of crystalline caffeine, the caffeine crystals were grinded into a very fine powder. A micro capillary tube was sealed at one end which acted as a micro test tube. The open end of the micro test tube was dipped into the vial containing pulverized caffeine crystal and was dropped inside a long glass tube until the sample reached a height of 0. 5-1cm. The same procedure was done on the standard caffeine sample. For the melting point determination, the two samples were secured in both sides of a thermometer. The thermometer was dipped into a beaker containing cooking oil heated at 150 degrees (oil bath). The temperature range between the first appearance of liquid within the sample until the disappearance of the last traces of solid was recorded. Conclusion The extraction of caffeine is a critical experiment, as it uses different chemistry principles such as solubility rules and a substance’s physical properties. The percent yield of 3. 96% is a reasonable finding since green teas are found to contain only 3-5% of its dry weight. Impurities which caused the melting point lowering of the sample could have resulted from experimental errors and could have occurred during the extraction and washing processes. In addition to experimental errors, the presence of soluble tannins in tea leaves complicates the isolation of caffeine, this could have been fixed in the solid-liquid extraction state through the addition of CaCO3 to separate tannins and keep them suspended in the water.

REAL ESTATE URBAN PLANNING PRACTICES IN EUROPE + GEOGRAPHY Essay

REAL ESTATE URBAN PLANNING PRACTICES IN EUROPE + GEOGRAPHY - Essay Example Therefore, economic efficiency entails producing the right (allocative) amount in the proper manner (productive efficiency). Distributional-justice means the distribution of impacts between known societal cohorts such as the rich or the poor, those owning cars and those without. It focuses on the minimization of the segregation or discrimination of each group based on classes in order to ascertain equity (McIntosh, 2004). In this essay, the researcher seeks to investigate and uncover the reasons behind the contradiction between the conventional economic efficiency frameworks in Europe by argument for and against the proportion that in Europe, economic efficiency calls for expansion of large shopping centres, usually out-of-town, while environmental and distributional-justice considerations often indicate that retailing should remain within the urban area / town centre. Europe’s economic efficiency calls for expansion of large shopping centres, usually out-of-town. Urban planning policy makers in Europe have shifted their attention to advice owners of large shopping centers to diversify off-cities. The urban planners advocate for such a strategy in order to ensure resource efficiency based on the utilization of the limited resources in a more sustainable manner. Such a strategy points towards the EU’s vision pushing for the economic growth while respecting scarcity of resources and planetary boundaries. The proponents of such strategies hold that economic efficiency is only achievable through ensuring both allocative and productive efficiency. Millions of Companies and consumers need to transform their production and consumption frameworks. Such transformation are feasible through a harmonious interactions of policy, investment, financing and innovation. The EU†s 2020 growth strategy projects a smart, sustainable and inclusive economy. A Roadmap to a resource-efficient Europe is the blueprint (Committee on spatial development,
