Heckerman [ ] , and Bering and Serpinskii [ ] indicate that silica surface consists of siloxane network in the bulk, while the hydroxyl groups are attached onto silicon atoms. However these groups are not equivalent in their adsorption or reaction behavior. Fig 1a represents a general arrangement on a silica surface. Belyakova et al. identifies that the number of hydroxyl (Silanol) group on different type of silica surfaces are same i.e. 4 -5 SiOH groups per nm2. Lange [ ] identifies that water associates
Identifying features and key components of unknown chemical mixtures are an essential part of chemistry. In many cases it is necessary to analyses and understand the chemical makeup of pharmaceuticals. Qualitative analysis is a method of testing a chemical mixture to determine its chemical makeup, such as its functional group. Identifying functional groups of an unknown compound are important, as it helps in understanding how a chemical acts under certain conditions, such as when changing physical
Chitosan is a cationic copolymer of glucosamine and N-acetylglucosamine (Mourya, Inamdar,&Tiwari, 2010).Due toits non-toxicity, biodegradability, biocompatibility, bioadhesivity, antimicrobial activity and physicochemical and biological properties, chitosan can be applied in a variety of fields. However, the poor solubility in water and most common organic solvents limits its applications (Dash, Chiellini, Ottenbrite, &Chiellini, 2011).According to the literature (Du & Hsieh, 2008; Mourya, Inamdar
Anorexia Nervosa (AN) was the first eating disorder to be classified, with some specific diagnostic criteria developed in the 1970s (Fairburn & Brownell, 2002). AN is a serious psychiatric disorder in terms of aetiology and epidemiology. 0.48% of prevalence of AN is estimated in girls who fall under the 15-19 age group (Lock et al., 2012). In AN, pathological thoughts and behaviours concerning food and weight, as well as emotions about appearance, eating and food co-occur (Lock et al., 2012). These
Kripkenstein: Rule and Indeterminacy ABSTRACT: Indeterminacy theories, such as Wittgenstein's and Kripke's indeterminacy principle on rules and language and Quine's indeterminacy of radical translation, raise some fundamental questions on our knowledge and understanding. In this paper we try to outline and interpret Wittgenstein's and Kripke's indeterminacy, and then compare it to some other related theories on indeterminacy of human thinking, such as raised by Hume, Quine, and Goodman. Quine's
The more challenging sceptical arguments do not depend on imposing high standards for knowledge or justification. Rather, the scepticism they imply is radical. It is not just the case that we can have all kinds of good reasons for what we believe, though those reasons do not quite measure up to the standards required by genuine knowledge. The radical sceptic questions whether we ever have the slightest reason for believing one thing rather than another, so we can never even get to the point of justified
Evil and the Possibility of the Conversion into Good According to Kant, radical evil is the deep inherent blemish of our species that does not spare even the best of people. Despite judging the extirpation of such evil as an impossibility, Kant holds out the possibility of converting evil into good by means of human forces. But how can this be given the radical evil of human nature? I articulate various problems that arise from Kant’s conception of conversion while exploring certain resources
Adoption: The Process Adoption is metamorphosing into a radical new process that is both sweeping the nation and changing it. But this process is not an easy one, there are many steps to go through. Through research it is made a lot easier. Adoption is a also a highly visible example of a social institution that has benefits from and been reshaped by both the Internet and the exponential growth of alternative lifestyles, from single to transracial to gay. It is accelerating our transformation into
Question: What means did reformers and radicals use to communicate their messages and how did these means influence their ideologies? Over the first Century and a half of American History, Reformers and Radicals found many innovative and effective ways to communicate their ideas to the country. Today, sending a message across the country can be as easy as writing an e-mail, and mass communication can be achieved as easily as setting up a website or buying a television advertisement. It is hard for
Dostoyevsky’s Notes from Underground has been deemed a strange literary piece (Roberts 2). It is written in two parts, contains a neurotic character that is unsettling to some readers, and addresses the Social Radicalist ideology that was popular during that time (Roberts 2; Frank 2). However, it can be argued that this character is portrayed in such a way that he is self-absorbed, petty, and imprudent for good reason. During the time that this work was written, Social Radicalists were spreading
Review - Revolting Librarians Redux: Radical Librarians Speak Out Who can resist a book with a chapter titled, "Labia Lumps, Chunky Discharge, and Other Things They Never Taught Me in Library School"? Released this past summer, Revolting Librarians Redux: Radical Librarians Speak Out takes no prisoners as its contributors ponder everything from the backtracking of '60s values by ALA's baby boomers to librarian imagery in erotica. This edited volume is a sequel to a 1972 self-published book titled
durante la Dictadura. La postura de Buero defendÃa el posibilismo, es decir, aprovechar cualquier resquicio que permitiera la censura franquista. Sastre, por el contrario, consideraba esta actitud como una claudicación y optó por un teatro radical que encontró grandes dificultades para llevar a los escenarios. Antonio Buero Vallejo falleció en Madrid, el 28 de abril de 2000. 3.ARGUMENTO La historia se desarrolla en la escalera de un edificio, en el cual se encuentran los vecinos
The Radical Period of The French Revolution By the end of 1971, Europe was preparing to witness the end of a seemingly triumphant revolution in France. The country was restructuring its government in a forceful and bloodless manner, while the tyrant King Louis the XVI agreed to the demands of the masses (albeit without much choice). However, due to the fanatical aspirations of men such as Danton, Marat and Robespierre,it would be only a matter of months before the moderate stage of social
Atwood's novel The Handmaid's Tale, a society whose purposes are functional and practical roles is depicted. In Atwood's eyes, a society like Gilead's was perfectly credible, and in many ways I agree with her. The purpose of writing about such a radical society is not for one to panic into thinking that this could happen any time, nor is it for one to completely discard the idea. Instead, it's purpose is solely to warn us of the dangers already present in our own society, such as the uncontrollable
Radical Ideas in Jane Eyre Charlotte Bronte knew what she was doing when she assumed the pseudonym of Currer Bell. In Jane Eyre she wanted to pose radical ideas regarding the role of women in the 19th century, but being a sensible woman, she knew that society would never accept having a woman pose these new views. It would be altogether too logical and self-praising. Though the author was never credited for the published novel it must have been equally fulfilling for her to know that people
the New Left continued to take on thousands of members as it developed a more radical approach in its opposition to racism and the Vietnam War. Practically synonymous with the New Left, Student’s for a Democratic Society (SDS) argued that militant tactics showed young people that actions could make a difference. SDS stated: "we can make a difference, we can hope to change the system, and also that life within the radical movement can be liberated, fulfilling, and meaningful." Student unrest passed
sharing when a variety of thoughts are in conflict, not imposing. They hated conservatives because they like to preserve the system, and for them change had to be very small, and slow, while fascist wanted radical change now. Fascism and communism had a lot in common. They both wanted radical change,...
Opinions of Radical Environmentalism The two articles I am going to look at are Radical Environmentalists vs. the Beavers by Jack Alan Brown Jr. and Environmentalists are Mean Green Joes by F.R. Duplantier. Radical Environmentalism is now a common term in our vocabulary. When you here the term what do you think about? I think about all the things that the environmentalists talk about and all the ideas brought to the table, good and bad. In the two articles I read they are both on the same subject
reactions begins; Cl2 → 2Cl●. A free radical reaction follows. Free radical reactions are reactions that involve free radicals. Free radicals are singular atoms or molecules that have one unbonded electron, which is denoted with a ●, or dot, next to the element or molecule. The second step commences when one of the original radical chlorine atoms combines with methane to create a radical methyl group and hydrochloric acid; CH4 + Cl● → CH3● + H Cl. The radical methyl group then becomes an intermediate
The Yellow Wallpaper as an Attack on Radical Feminism “The Yellow Wallpaper” explores mental illness and, through this exploration, presents a critique of the place of women in a patriarchal society. Interestingly, Charlotte Perkins Gilman never intended the latter. The primary intent of her short story is to criticize of a physician prescribed treatment called rest cure. The treatment, which she underwent, required female patients to “’live as domestic a life as possible’” (Gilman). This oppressive
