CR Gas

	CR Gas CR gas or dibenzoxazepine (chemical name dibenz 'b'',''f''1,4]oxazepine, is an incapacitating agent and a lachrymatory agent. CR was developed by the British Ministry of Defence as a riot control agent in the late 1950s and early 1960s. A report from the Porton Down laboratories described exposure as "like being thrown blindfolded into a bed of stinging nettles", and it earned the nickname "firegas". In its effects, the CR gas is very similar (but twice as potent) to o-chlorobenzylidene malononitrile CS gas, even though there is little structural resemblance between the two. For example, 2 mg of dry CR cause skin redness in 10 min, 5 mg cause burning and erythremia, 20 mg- strong pain. Water usually amplifies the pain effect of CR on skin. CR aerosols cause irritation as 0.0002 mg/L, which becomes intolerable at 0.003 mg/L. The lethal dose of CR through air inhalation is LD50 = 350 mg·min/L. Physical properties and deployment CR is a pale yellow c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Incapacitating Agent The term incapacitating agent is defined by the United States Department of Defense as: :"An agent that produces temporary physiological or mental effects, or both, which will render individuals incapable of concerted effort in the performance of their assigned duties." It describes an agent which renders a person unable to harm themselves or others, regardless of consciousness. Lethal agents are primarily intended to kill, but incapacitating agents can also kill if administered in a potent enough dose, or in certain scenarios. The term "incapacitation," when used in a general sense, is not equivalent to the term "disability" as used in occupational medicine and denotes the inability to perform a task because of a quantifiable physical or mental impairment. In this sense, any of the chemical warfare agents may incapacitate a victim; however, by the military definition of this type of agent, incapacitation refers to impairments that are temporary and nonlethal. Thus, riot-control ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Carcinogen A carcinogen is any substance, radionuclide, or radiation that promotes carcinogenesis (the formation of cancer). This may be due to the ability to damage the genome or to the disruption of cellular metabolic processes. Several radioactive substances are considered carcinogens, but their carcinogenic activity is attributed to the radiation, for example gamma rays and alpha particles, which they emit. Common examples of non-radioactive carcinogens are inhaled asbestos, certain dioxins, and tobacco smoke. Although the public generally associates carcinogenicity with synthetic chemicals, it is equally likely to arise from both natural and synthetic substances. Carcinogens are not necessarily immediately toxic; thus, their effect can be insidious. Carcinogens, as mentioned, are agents in the environment capable of contributing to cancer growth. Carcinogens can be categorized into two different types: activation-dependent and activation-independent, and each nature impacts their ...

picture info	Tear Gas Tear gas, also known as a lachrymator agent or lachrymator (), sometimes colloquially known as "mace" after the early commercial aerosol, is a chemical weapon that stimulates the nerves of the lacrimal gland in the eye to produce tears. In addition, it can cause severe eye and respiratory pain, skin irritation, bleeding, and blindness. Common lachrymators both currently and formerly used as tear gas include pepper spray (OC gas), PAVA spray ( nonivamide), CS gas, CR gas, CN gas (phenacyl chloride), bromoacetone, xylyl bromide and Mace (a branded mixture). While lachrymatory agents are commonly deployed for riot control by law enforcement and military personnel, its use in warfare is prohibited by various international treaties.E.g. the Geneva Protocol of 1925 prohibited the use of "asphyxiating gas, or any other kind of gas, liquids, substances or similar materials". During World War I, increasingly toxic and deadly lachrymatory agents were used. The short and long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Pepper Spray Pepper spray, oleoresin capsicum spray, OC spray, capsaicin spray, or capsicum spray is a lachrymatory agent (a compound that irritates the eyes to cause a burning sensation, pain, and temporary blindness) used in policing, riot control, crowd control, and self-defense, including defense against dogs and bears. Its inflammatory effects cause the eyes to close, temporarily taking away vision. This temporary blindness allows officers to more easily restrain subjects and permits people in danger to use pepper spray in self-defense for an opportunity to escape. It also causes temporary discomfort and burning of the lungs which causes shortness of breath. Pepper spray was engineered into a spray originally for defense against bears, mountain lions, wolves and other dangerous predators, and is often referred to colloquially as bear spray. Kamran Loghman, the person who developed it for use in riot control, wrote the guide for police departments on how it should be used ...

picture info	2013 Protests In Turkey A wave of demonstrations and civil unrest in Turkey began on 28 May 2013, initially to contest the urban development plan for Istanbul's Taksim Gezi Park. The protests were sparked by outrage at the violent eviction of a sit-in at the park protesting the plan. Subsequently, supporting protests and strikes took place across Turkey, protesting against a wide range of concerns at the core of which were issues of freedom of the press, of expression and of assembly, as well as the alleged political Islamist government's erosion of Turkey's secularism. With no centralised leadership beyond the small assembly that organised the original environmental protest, the protests have been compared to the Occupy movement and the May 1968 events. Social media played a key part in the protests, not least because much of the Turkish media downplayed the protests, particularly in the early stages. Three and a half million people (out of Turkey's population of 80 million) are estimated to have t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	2011 Egyptian Revolution The 2011 Egyptian revolution, also known as the 25 January revolution ( ar, ثورة ٢٥ يناير; ), began on 25 January 2011 and spread across Egypt. The date was set by various youth groups to coincide with the annual Egyptian "Police holiday" as a statement against increasing police brutality during the last few years of Hosni Mubarak's presidency. It consisted of demonstrations, marches, occupations of plazas, non-violent civil resistance, acts of civil disobedience and strikes. Millions of protesters from a range of socio-economic and religious backgrounds demanded the overthrow of Egyptian President Hosni Mubarak. Violent clashes between security forces and protesters resulted in at least 846 people killed and over 6,000 injured. Protesters retaliated by burning over 90 police stations across the country. The Egyptian protesters' grievances focused on legal and political issues, including police brutality, state-of-emergency laws, lack of political freedom, civil l ...

	Palliative Palliative care (derived from the Latin root , or 'to cloak') is an interdisciplinary medical caregiving approach aimed at optimizing quality of life and mitigating suffering among people with serious, complex, and often terminal illnesses. Within the published literature, many definitions of palliative care exist. The World Health Organization (WHO) describes palliative care as "an approach that improves the quality of life of patients and their families facing the problems associated with life-threatening illness, through the prevention and relief of suffering by means of early identification and impeccable assessment and treatment of pain and other problems, physical, psychosocial, and spiritual." In the past, palliative care was a disease specific approach, but today the WHO takes a more broad approach, that the principles of palliative care should be applied as early as possible to any chronic and ultimately fatal illness. Palliative care is appropriate for individuals with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
