Physics in The Atmospheric Chemistry Experiment Research Paper

Physics in The Atmospheric Chemistry Experiment - Research Paper Example This paper discusses the physics involved in the experiment and how it is used to understand the effect of changes in the atmospheric layers on the ozone layer over the Arctic pole. Various parameters like temperature, pressure, etc. have been measured by custom made apparatus like the interferometers, spectrometers, spectrophotometers, etc. Launch- ACE used two major instruments in the mission. While the first instrument was a Fourier Transform Spectrometer (FTS), the other instrument was a dual optical spectrometer (Bernath, na). It was launched by NASA on August 12, 2003 using a Pegasus XL rocket at 650km above the Earth. The satellite was launched at an angle of 740 and orbited the Earth to cover tropical, mid-latitude and the Polar regions. The satellite operated in the UV-Visible-NIR region of the spectrum with the ACE-FTS being used in the NIR region while the MAESTRO Spectrophotometer was being used over the UV-VIS-NIR region (ACE, 2009). FTS operated in the range of 2-13 microns with a high resolution of 0.02cm-1 and a vertical resolution of 4km to up to 150km. the MAESTRO spectrophotometer operated in the UV-VIS-NIR spectral region of 285-1030nm with a vertical resolution of 1-2 km. ... Apart from this information, the satellite was also used to provide vertical profile information for temperature, pressure and the various molecules and their mixing ratios present in the atmospheric layers (ACE, 2009). Constituents- The primary instruments in the satellite are the FTS and the MAESTRO. The ACE-FTS is a Michelson interferometer with two corner cubes for producing the path difference with an end mirror which increases the path difference. The interference fringes are produced with a diode laser operating at 1500nm which are further Fourier Transformed to give the spectra. It has two detectors operating below 100K. Two imagers, one a Visible imager and other a near-IR imager at 0.525 and 1.02 microns are used to study the atmospheric absorption of aerosols and the clouds in the region. These two wavelengths are used for study as they are free of any absorption by the molecules present in the two layers, particularly the stratosphere (Bernath, 2005, pp25-26). The altitude profile information is sun tracked by detectors with 256x256 pixel sensors and a field view of 30mrad and a signal-to-noise ratio of more than 1000. The MAESTRO uses two spectrographs in the two overlapping windows which are 280-550nm and 500-1030nm with a resolution of 2nm. It is noted that the use of two spectrographs enhances the stray-light performance and enables the simultaneous measurement of two spectral bands at a narrow resolution. It also consists of photodiode detectors and a concave grating with an entrance slit always held horizontal to the sunset and sunrise. It also has a vertical resolution of 1-2km and a signal-to-noise

Promote The Human Rights Essay Example for Free

Promote The Human Rights Essay Identify legislation and policies that are designed to promote the human rights, inclusion equal life chances and citizenship of individuals with learning disabilities. Legislation and policies are implemented to support and protect the human rights and inclusion of individuals with learning disabilities Some of these Acts and policies include: The Human Rights Act 1998 The Human Rights Act in the United Kingdom came into force on the 2nd October 2000 and underpins many of the core values which we in the care industry must adopt. It ensures the rights of individuals and means that they are entitled to seek help from the courts if they believe that their human rights have been infringed. The Human Rights Act â€Å"guarantees† basic human rights: the right to life; the right to liberty and security of person; the right to freedom of thought, conscience and religion; the right to marry and found a family etc. The care sector has the responsibility to promote and respect human rights as a core part of their day-to-day work, from drafting policies regulations and rules, through internal staff and policy issues, administration, decision making, to implementing policy and working with members of the public. The basic human rights which the care sector has the responsibility to promote are: †¢The right to life (relevant to protection of clients’ physical and mental wellbeing) †¢The right to freedom from torture and inhuman or degrading treatment †¢The right of respect for private and family life, home and correspondence (relevant to confidentiality) †¢The right to freedom of thought, conscience or religion (relevant to respecting equality and diversity) †¢The right of protection from discrimination †¢The right to marry and found a family †¢The right to education †¢Free elections by secret ballot The Equality Act 2010 Brought in to replace the previous anti-discriminatory laws. It identifies nine protected characteristics; age, disability, marriage/civil partnership, pregnancy/maternity, race, religion/belief, gender, sexual orientation and gender reassignment. The Care Standards Act 2000 The Care Standards Act 2000 reforms the regulatory system for care services in England and Wales. It replaces the Registered Homes Act 1984, and associated regulations, which is intended to be repealed from 1 April 2002. The National Minimum Standards for registered care services are issued by the Department of Health as part of the implementation of the Care Standards Act 2000. These standards include requirements about the competence of the work force including their suitability, experience and qualifications. The Care Standards Act sets out a broad range of regulation making powers covering, amongst other matters, the management, staff, premises and conduct of social care and independent healthcare establishments and agencies. The aim is to ensure that the care of vulnerable people, in differing types of supported housing is properly regulated, to improve care standards and introduce consistency in the regulation of services provided. The Protection of Vulnerable Adults (POVA)/Safeguarding Vulnerable Adults (SVA) scheme will act as a workforce ban on those professionals who have harmed vulnerable adults in their care. It will add an extra layer of protection to the pre-employment processes, including Criminal Records Bureau checks, which already take place and prevent known abusers from entering the care workforce. This Care Act 2000 was replaced by the Health Social Care Act 2008 with the aim to primary focus of the Health and Social Care Act 2008 was to create a new regulator whose purpose was to provide registration and inspection of health and adult social care services together for the first time, with the aim of ensuring safety and quality of care for service users. Safeguarding Vulnerable Adults Group Act 2006 The purpose of the Safeguarding Vulnerable Groups Act 2006 is to restrict contact between children and vulnerable adults and those who might do them harm. The Mental Health Act 2007 The law which governs the compulsory treatment of certain people who have a mental disorder is the Mental Health Act 1983. The main purpose of the Mental Health Act 2007 is to amend the 1983 Act. It is also being used to introduce â€Å"deprivation of liberty safeguards† through amending the Mental Capacity Act 2005; and to extend the rights of victims by amending the Domestic Violence, Crime and Victims Act 2004. Mental Capacity Act 2005 The Mental Capacity Act 2005 provides a comprehensive framework for decision making on behalf of adults aged 16 and over who lack capacity to make decisions on their own behalf. The Act applies to England and Wales. Scotland has its own legislation. The Act sets out a number of basic principles that must govern all decisions made and actions taken under its powers. These are rooted in best practice and the common law and are designed to be fully compliant with the relevant sections of the Human Rights Act. Where confusion arises about how aspects of the Act should be implemented, it can be extremely helpful to refer back to them. Actions or decisions that clearly conflict with them are unlikely to be lawful, although there may be occasions on which they are in tension with each other and some balancing will be required. Valuing People Now Valuing People Now is an opportunity to help get better lives for all people with learning disabilities and their families, including those with complex needs, and from black and minority ethnic communities. Valuing People Now says people with a learning disability have the same human rights as everyone else Putting People First Putting People First (PPF) sets out the direction for adult social care. It is a shared commitment by the Government, local councils and service providers to ensuring that people who need care and support have choice, flexibility and control to live their lives the way they wish.

Gender And Gender Norm Communications Essay

Gender And Gender Norm Communications Essay The aim of this essay is to analyse how gender norms shape performances of attractiveness and how physical norms and performances of attractiveness are related to the construction of gender and gender norms. In the first section, definition of gender and gender norms will be provided and reference is made to theories put forward by academics in the field of gender studies. Following this, attractiveness in terms of the body as a form of capital will be evaluated with a particular focus on physical attractiveness. In the third section, this paper will produce some insight into how masculinity and femininity are represented in the media and the impact of media on the construction of gender and gender norms as well as performances of attractiveness. Finally, the concept of â€Å"metrosexual† and â€Å"tomboy† will be presented as a primary example of new tendencies to challenge traditional gender norms in order to support the idea that gender norms are not fixed and subje cted to be changed over time. 1. Gender and gender norm To begin with, it is essential to consider what is meant by gender and gender norms. This section will explore the definition of gender and gender norms and reference is made to the works of academics in the field of gender studies. Gender, in Hermess words, â€Å"is the cultural significance given to biological difference of reproductive organs. It refers to men and women, as well as to appropriate ways to be a man or a woman (masculinity and femininity)† (Hermes,2007,p.190). It can be seen that, in Hermess account, peoples gender are socially constructed , are culturally built upon male or female bodies. This notion of gender is widely accepted in our society and many feminists defined ‘gender in relation to ‘sex. Feminists assume that sex is biological given and gender is cultural or social construction of this given sex (Gauntlett , 2002). When it comes to gender, it not only means that one is man or woman, â€Å"but rather a set of meanings that sexes assume in particular societies. The operation of gender in our society takes up these sets of meaning, organizes them as masculinity or femininity, and matches or line them up with male and female bodies† (Cranny-Francis et al, 2003, p.3). In other words, feminists argued that people will have certain kinds of identity or role due to the fact that they are ‘male or ‘female in terms of biology (Gauntlett, 2002). In 1987, West and Zimmerman conceptualise ‘gender not â€Å"as set of traits, nor variable, nor a role† but as something people ‘do recurrently in their interactions with others in social life. They stated that: â€Å"Doing gender involves a complex of socially guided perceptual, interactional, and micropolitical activities that cast particular pursuits as expression of masculine and feminine ‘natures† (West and Zimmerman,1987,p.14). For instance, when a man hold a womans hand and guide her across the street, he â€Å"does† being masculine and his partner â€Å"does† being feminine when she allows to be guided (West and Zimmerman,1987). In West and Zimmermans account, â€Å"doing gender is unadvoidable† because societys structure is based on the â€Å"essential† differences between male and female. In other words, individuals just can make their activity accountable by performing it as a woman or a man. Butler: â€Å"the binary divide between masculinity and femininity is a social construction built on the binary divide between men and women which is also a social construction (Gauntlett,2002,pp.135)†. No distinction btw sex and gender A person has a masculine gender not really base on he has a male body or not. Gender is socially constructed and is performed by the individual subject through the repetition of à   through the process of social construction(butler) Gender is a performance -> link: the performance of attractiveness is the performance of gender, people express their masculinity or femininity through their performance of attractiveness. So, what is the embodiment of masculinity and femininity? How can we assess the masculinity or femininity of a person? It depends on gender norms. Gender is a performance, therefore, gender norm can be understood as the social expectation of people to perform their gender in everyday life. Gender norm is a set of rules of social order (gender is the repetition of acts -> people everydays actions reinforce and reproduce a set of expectations -> a kind of social structure -> its varied in different context such as history or culture and flexible, can be changed over time) (see Giddens in Gauntlett) In our society, gender norms seem to be established base on how people look in term of physical appearance due to the fact that they are male or female , how they present their self, what kind of activities they take part in. Gender as a social structure: Giddens (1998) notes that: â€Å" Society only has form, and that form only has effect on people, in so far as structure is produced and reproduced in what people do† (quoted in Gauntlett, 2002,p.95). It can be implied that 2. Attractiveness in term of body as a form of capital 3. Attractive men and women and the representation of gender in the media ( Masculine and feminine gender norms) Who can be seen as attractive (discuss about traditional gender norms) Masculinity and femininity in media Media change gender norms In summary, gender is unstable and subject to change in different context and in different time. As Hermes (2007†,p.191) put it: â€Å"Gender does not assume the same cultural significance everywhere, and gender codes have changed significantly over time†. 4. ‘Metrosexual and ‘tomboy: against the traditional norms In an attempt to demonstrate the idea that gender norms are flexible and can be changed, this section will produce some insight into the concept of ‘metrosexual and ‘tomboy which can be seen as against the traditional masculine and feminine norms. â€Å"By understanding gender as the crucially important difference between men and women, heterosexuality maintain itself as absolute norm†. or â€Å"we understand the difference btw men and women as fundamental and as the norm† (Hermes, 2007,p.197) -> masculinity in many ways is defined as how not to appear to be effeminate , femininity is meant not to be masculine -> link to â€Å"metrosexual†and â€Å"tomboy†-> challenge the traditional norms. ‘Metrosexual Conclusion To bring this paper to a close, I summarise the main points here: gender norms shape performances of attractiveness, at the same time are changed and reconstructed by the way individuals perform their gender. Media as a guidance has exerted far reaching influence on peoples perception of gender norms and performances of attractiveness. Moreover, by representing counter-hegemonic images such as ‘metrosexual man, media has played a vital role in the reconstruction of gender and gender norms. This paper set out to examine how gender norms shape performance of attractiveness. Firstly, in order to define gender and gender norms, a literature review was presented. Secondly, this essay produced some insight into how attractiveness in terms of the body as a form of capital and discussed how physical norms and performances of attractiveness are related to the construction of gender and gender norms. In the third section, the effect of the media on peoples performances of attractiveness was considered through the way masculinity and femininity are represented in advertising, magazine, and television. In attempt to demonstrate the idea that gender norms are flexible and can be changed, evidence was presented in relation to the concept of ‘metrosexual and ‘tomboy. In conclusion, this assignment suggested that gender norms remain crucial to performances of attractiveness in our society and varied in different context such as history or culture. It could be argued that by the way people choose to perform their gender as well as perform their attractiveness, they are simultaneously reinforcing and changing gender norms.

Essay on the Downfall of Man in John Miltons Paradise Lost

The classic tragedy Paradise Lost, written by John Milton, demonstrates how the fallen angels lose the paradise they have been given, and how this fall directly effects the downfall of man as well. Before anything ever was, all matter was chaos; utter darkness and filth. A mighty being, God, rose up out of chaos and created the firmament called Heaven, and all the universe (4). The angels, and archangels that populated Heaven, danced in the realms of the magnificent light (8). Lucifer, the highest archangel, stepped fourth and accused God of his power, jealously tying to take it from him. Almighty God cast him, and his followers out of the sublime realm. The fallen angels transcended back into the filth of chaos. This chaos being the exact opposite of paradise, Hell. This establishes how paradise was lost.    "To mortal men, he with his horrid crew Lay vanquished, rolling in the fiery gulf Confounded though immortal. But his doom Reserved him to more wrath; for now the thought Both of lost happiness and lasting pain Torments him; round he throws his baleful eyes, That witnessed huge affliction and dismay Mixed with obdurate pride and steadfast hate" (8).    God gave Lucifer the appearance of a serpent, and called that serpent Satan. Satan, unable to rise from chaos, built a palace that was called Pandemonium (5). Satan gathers a council of his fallen colleagues to further wage war against God in order to take Heaven.    "High on a throne of royal state, which far Outshown the wealth of Ormus and of Ind Or where the gorgeous East with richest hand Showers on her kings barbaric pearl and gold, Satan exalted sat, by merit raised To that bad eminence... ...econd edn.

Analyse Hytners version by comparing and reviewing the play scenes Essay

In this essay I am going to analyse Hytners version by comparing and reviewing the play scenes. My essay is also going to include comments on the language, opening scenes, settings and characters. I think that the stage play is longer than the screen play because the screen play is summarized, this is because in films you don’t have long speech because there are other things around that help you understand, for example when the girls are in court and Abigail pretends to get cold when she see Mary Warren but in the book this is written in a long speech but in the video it is cut down because there is body language used also in the stage play Parris takes books from Hale but in the screenplay John Proctor takes the books because Proctor is the main character, so the main character should welcome Hale at this time Parris is inside with the girls. We are introduced to the one of the main characters when the film begins which is at the night. The first shot we see of the film is Abigail sitting bolt upright in bed because she can’t sleep because of John Proctor. She can’t wait to go cast spells in the woods, which the girls had planned and is looking forward to it. The movement of the girls is very suspicious because you are curious were they are going because they do everything planned, you be asking yourself, why are there so m any and why are they so quiet? I think that the dancing scene brings a lot of excitement to the audience. And when Abigail kills the chicken and licks the blood. I think she is stupid there and heartless because she is killing someone just for her love also the audience is very shocked when they see her doing this. Our attention is on Abigail throughout the opening scene because she’s the first person we see and she takes the lead by drinking chicken blood, she is made to be attractive to the men. Witchcraft starts when Betty falls ill, and everyone thinks she has been witched, also Abigail says they were only dancing but the video shows them conjuring spirits. The main characters in the crucible are John Proctor and Abigail Williams. Abigail is very evil when she pretended that Mary is sending her spirit and making the girl come cold, she acts different at the time, and she is very blue when she is demonstrating this act. John Proctor is powerful in his own way for example when he tells Abigail he don’t lover her and pushes her away, he also is very confident when he confesses the affair he had with Abigail. He is also a risk taker because when he doesn’t sign the paper and has to be hanged But John Proctor is a caring and calm to his children and wife and the village also think that he is an excellent man but the village and his family don’t know that he has been faithful by having an affair behind there back. John Proctor is not a very religious man he had not gone to church throughout the whole play. When Abigail is initially talking to Betty and the girls, the camera is facing Abigail when she speaks the effect this has is that we can see things from Abigail perspective. The lighting is very dim and dreamy the only light we can see is the natural light from the windows. The style of lighting ads to the mood of the scene by then we can realize that this scene is going to be important that the conversation between Abigail and Betty is serious and dull. When the girls are in the woods the lighting is misty, there is a bit of light on the girls mostly on Abigail as there is talking it goes from one person to another. Overall I think that the screen play is better than stage play because in the screen play I could understand what is happening but in the stage play I was confused, because I had to read it and it was quiet confusing but when I watched the video it had people to it so they help me understand more.

10 Silicon Facts (Element Number 14 or Si)

10 Silicon Facts (Element Number 14 or Si) Silicon is element number 14 on the periodic table, with the element symbol Si. Here is a collection of facts about this interesting and useful element: Silicon Fact Sheet Credit for discovering silicon is given to  Swedish chemist Jà ¶ns Jakob Berzelius, who reacted potassium fluorosilicate with potassium to produce amorphous silicon, which he named silicium, a name first proposed by Sir Humphry Davy in 1808. The name derives from the Latin words silex or silicis, which mean flint. Its probable English scientist Humphry Davy may have isolated impure silicon in 1808 and  French chemists Joseph L. Gay-Lussac and Louis Jacques Thà ©nard may have produced impure amorphous silicon in 1811. Berzelius is credited for the elements discovery because his sample was purified by repeatedly washing it, while earlier samples were impure.Scottish chemist Thomas Thomson named the element silicon in 1831, keeping part of the name Berzelius had given, but changing the ending of the name to -on because the element showed more similarities to boron and carbon than to the metals that had -ium names.Silicon is a metalloid, which means it has properties of both metals and nonmetals. Like other metalloids, silicon has different forms or allotropes. Amorphous silicon is usually seen as a gray powder, while crystalline silicon is a gray solid with a shiny, metallic appearance. Silicon conducts electricity better than nonmetals, yet not as well as metals. In other words, its a semiconductor. Silicon has a high thermal conductivity and conducts heat well.  Unlike metals, its brittle, and not malleable or ductile. Like carbon, it usually has a valence of 4 (tetravalent), but unlike carbon, silicon can also form five or six bonds.   Silicon is the second most abundant element on Earth by mass, making up over 27% of the crust. Its commonly encountered in silicate minerals, such as quartz and sand, but only rarely occurs as a free element. Its the 8th most abundant element in the universe, found at levels of about 650 parts per million. Its the principal element in a type of meteorite called aerolites.Silicon is needed for plant and animal life. Some aquatic organisms, such as diatoms, use the element to construct their skeletons. Humans need silicon for healthy skin, hair, nails, and bones, and to synthesize the proteins collagen and elastin. Dietary supplementation with silicon may increase bone density and reduce the risk of osteoporosis.Most silicon is used to produce the alloy ferrosilicon. Its used to produce steel. The element is purified to make semiconductors and other electronics. The compound silicon carbide is an important abrasive. Silicon dioxide is used to make glass. Because silicate minerals are c ommon, silicon oxides form rocks and are used to make glass and ceramics. Like water (and unlike most chemicals), silicon has a higher density as a liquid than as a solid.Natural silicon consists of three stable isotopes: silicon-28, silicon-29, and silicon-30. Silicon-28 is the most abundant, accounting for 92.23% of the natural element. At least twenty radioisotopes are also known, with the most stable being silicon-32, which has a half-life of 170 years.Miners, stone cutters, and people who live in sandy regions may inhale large quantities of silicon compounds and develop a lung disease called silicosis. Exposure to silicon may occur by inhalation, ingestion, skin contact, and eye contact. The Occupational Safety and Health Administration (OSHA) sets the legal limit for workplace exposure to silicon to  15  mg/m3  total exposure and 5  mg/m3  respiratory exposure for an 8-hour workday.Silicon is available at extremely high purity. Molten salt electrolysis of silica (silicon dioxide) or other silicon compounds can be used to obtain the element at 99.9% purity for use in semiconductors. The Siemens process is another method used to produce high purity silicon. This is a form of chemical vapor deposition where gaseous trichlorosilane is blown across a pure silicon rod to grow polycrystalline silicon (polysilicon) with a purity of 99.9999%.   Silicon Atomic Data Element Name: Silicon Element Symbol: Si Atomic Number: 14 Classification: metalloid (semimetal) Appearance: Hard gray  solid with a silver metallic luster.
