Acid Attack
An acid attack, also called acid throwing, vitriol attack, or vitriolage, is a form of violent assault involving the act of throwing acid or a similarly corrosive substance onto the body of another "with the intention to disfigure, maim, torture, or kill". Perpetrators of these attacks throw corrosive liquids at their victims, usually at their faces, burning them, and damaging skin tissue, often exposing and sometimes dissolving the bones. Acid attacks can lead to permanent, partial, or complete blindness. The most common types of acid used in these attacks are sulfuric and nitric acid. Hydrochloric acid is sometimes used but is much less damaging. Aqueous solutions of strongly alkaline materials, such as caustic soda (sodium hydroxide), are used as well, particularly in areas where strong acids are controlled substances. The long-term consequences of these attacks may include blindness, as well as eye burns, with severe permanent scarring of the face and body, along with ...

Alkali
In chemistry, an alkali (; from ar, القلوي, al-qaly, lit=ashes of the saltwort) is a basic, ionic salt of an alkali metal or an alkaline earth metal. An alkali can also be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0. The adjective alkaline, and less often, alkalescent, is commonly used in English as a synonym for basic, especially for bases soluble in water. This broad use of the term is likely to have come about because alkalis were the first bases known to obey the Arrhenius definition of a base, and they are still among the most common bases. Etymology The word "alkali" is derived from Arabic ''al qalīy'' (or ''alkali''), meaning ''the calcined ashes'' (see calcination), referring to the original source of alkaline substances. A water-extract of burned plant ashes, called potash and composed mostly of potassium carbonate, was mildly basic. After heating this substance with calcium hydroxide (''slaked lim ...

Neutralization (chemistry)
In chemistry, neutralization or neutralisation (see spelling differences) is a chemical reaction in which acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution. The pH of the neutralized solution depends on the acid strength of the reactants. Meaning of "neutralization" In the context of a chemical reaction the term neutralization is used for a reaction between an acid and a base or alkali. Historically, this reaction was represented as :acid + base (alkali) → salt + water For example: :HCl + NaOH → NaCl + H2O The statement is still valid as long as it is understood that in an aqueous solution the substances involved are subject to dissociation, which changes the ionization state of the substances. The arrow sign, →, is used because the reaction is complete, that is, neutralization is a quantitative reaction. A more general definition is ...

Concentration
In chemistry, concentration is the abundance of a constituent divided by the total volume of a mixture. Several types of mathematical description can be distinguished: '' mass concentration'', ''molar concentration'', '' number concentration'', and '' volume concentration''. The concentration can refer to any kind of chemical mixture, but most frequently refers to solutes and solvents in solutions. The molar (amount) concentration has variants, such as normal concentration and osmotic concentration. Etymology The term concentration comes from the word concentrate, from the French , from con– + center, meaning “to put at the center”. Qualitative description Often in informal, non-technical language, concentration is described in a qualitative way, through the use of adjectives such as "dilute" for solutions of relatively low concentration and "concentrated" for solutions of relatively high concentration. To concentrate a solution, one must add more solute (for exam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychologist
A psychologist is a professional who practices psychology and studies mental states, perceptual Perception () is the organization, identification, and interpretation of sensory information in order to represent and understand the presented information or environment. All perception involves signals that go through the nervous syste ..., cognitive, emotional, and social processes and behavior. Their work often involves the experimentation, observation, and interpretation of how individuals relate to each other and to their environments. Psychologists usually acquire a bachelor's degree in psychology, followed by a master's degree or doctorate in psychology. Unlike psychiatrist, psychiatric physicians and psychiatric nurse-practitioners, psychologists usually cannot prescribe medication, but depending on the jurisdiction, some psychologists with additional training can be licensed to prescribe medications; qualification requirements may be different from a bachelor's d ...

Acid Survivors Foundation
The Acid Survivors Foundation is a Bangladeshi non-governmental organisation dedicated to raising awareness and preventing acid attacks and providing survivors with medical and legal aid. History The Foundation was founded in Dhaka in 1999 by British physician Dr John Morrison with considerable assistance from British surgeon, Dr Ronald Hiles and subsequently, a group of four concerned citizens namely i) Mr. Kazi Fazlur Rahman, former adviser to the caretaker president. ii) Dr. S. L. Sen, Plastic Surgeon. iii) Advocate Sigma Huda & iv) Mr. Selim Ahmed on 12 May 1999 with substantial support from UNICEF and the Canadian International Development Agency. Nasreen Huq a commanding personality in the field of social reform and human rights in Bangladesh campaigned internationally for ASF. In 2005, Monira Rahman the Ex-Executive Director of ASF was awarded the Human Rights Award by Amnesty International. Bangladesh's ASF has subsequently been used as a model organisation for th ...

Acid Survivors Trust International
Acid Survivors Trust International (ASTI) is a UK-based international non-profit organization aiming to end acid and burns violence at a global level. In addition to public education and awareness campaigns, ASTI supports organizations in Bangladesh, Cambodia, India, Nepal, Pakistan and Uganda that they have helped to form. The organization was founded in 2002 and is a registered charity under English law. Impact Acid Survivors Trust International's work has produced change in challenging acid violence. The organisation has been involved in many campaigns, such as those to introduce acid laws in Cambodia, Pakistan and Bangladesh. In the case of the latter, the incidence of recorded acid violence fell from 500 cases in 2002 to less than 100 in 2012, over a 70% reduction. ASTI are also actively involved in administering medical support for survivors: former ASTI trustee Dr Ron Hiles OBE, has performed over one thousand reconstructive surgery operations and trained hundreds of s ...

Scar
A scar (or scar tissue) is an area of fibrous tissue that replaces normal skin after an injury. Scars result from the biological process of wound repair in the skin, as well as in other organs, and tissues of the body. Thus, scarring is a natural part of the healing process. With the exception of very minor lesions, every wound (e.g., after accident, disease, or surgery) results in some degree of scarring. An exception to this are animals with complete regeneration, which regrow tissue without scar formation. Scar tissue is composed of the same protein ( collagen) as the tissue that it replaces, but the fiber composition of the protein is different; instead of a random basketweave formation of the collagen fibers found in normal tissue, in fibrosis the collagen cross-links and forms a pronounced alignment in a single direction. This collagen scar tissue alignment is usually of inferior functional quality to the normal collagen randomised alignment. For example, scars in ...
