Fog Cannon
Security smoke is a thermally generated white fog, aimed at inhibiting intruders from accessing items to steal, much used in the storage of high-value goods, and recommended by police and insurers. It consists of glycol or glycerine mixed with distilled water, which vaporises and then condenses in the air. History The market for using security smoke as a theft prevention tool came about because of an increase in the ability of thieves to circumvent existing physical security measures, often by simply raising the level of violence utilised to gain entry. Burglar alarms often have a delay of several minutes before police or private security are able to respond, meaning a well organised criminal has a period of time in which to enter and take what they like. Closed-circuit television Closed-circuit television (CCTV), also known as video surveillance, is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors.

Ya or Ja (Я я; italics: ) is a letter of the Cyrillic script, the civil script variant of Old Cyrillic Little Yus () or maybe even ' Ꙗ'. Among modern Slavic languages, it is used in the East Slavic languages and Bulgarian. It is also used in the Cyrillic alphabets used by Mongolian and many Uralic, Caucasian and Turkic languages of the former Soviet Union. Pronunciation The iotated vowel is pronounced in initial or post-vocalic positions, like the English pronunciation of in "yard". When follows a soft consonant, no sound occurs between the consonant and the vowel. The exact pronunciation of the vowel sound of depends also on the following sound by allophony in the Slavic languages. Before a soft consonant, it is , like in the English "cat". If a hard consonant follows or none, the result is an open vowel, usually []. In non-stressed positionsm, the vowel reduction depends on the language and the dialect. The standard vowel reduction in Russian, Russ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crime Prevention
Crime prevention is the attempt to reduce and deter crime and criminals. It is applied specifically to efforts made by governments to reduce crime, enforce the law, and maintain criminal justice. Studies Criminologists, commissions, and research bodies such as the World Health Organization, United Nations, the United States National Research Council, the UK Audit Commission have analyzed their and others' research on what lowers rates of interpersonal crime. They agree that governments must go beyond law enforcement and criminal justice to tackle the risk factors that cause crime, because it is more cost effective and leads to greater social benefits than the standard ways of responding to crime. Multiple opinion polls also confirm public support for investment in prevention. Waller uses these materials in '' Less Law, More Order'' to propose specific measures to reduce crime as well as a crime bill. The ''World Health Organization Guide'' (2004) complements the ''World Report on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Footnotes
A note is a string of text placed at the bottom of a page in a book or document or at the end of a chapter, volume, or the whole text. The note can provide an author's comments on the main text or citations of a reference work in support of the text. Footnotes are notes at the foot of the page while endnotes are collected under a separate heading at the end of a chapter, volume, or entire work. Unlike footnotes, endnotes have the advantage of not affecting the layout of the main text, but may cause inconvenience to readers who have to move back and forth between the main text and the endnotes. In some editions of the Bible, notes are placed in a narrow column in the middle of each page between two columns of biblical text. Numbering and symbols In English, a footnote or endnote is normally flagged by a superscripted number immediately following that portion of the text the note references, each such footnote being numbered sequentially. Occasionally, a number between brack ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mantrap (access Control)
A mantrap, security mantrap portal, airlock, sally port or access control vestibule is a physical security access control system comprising a small space with two sets of interlocking doors, such that the first set of doors must close before the second set opens. Airlocks have a very similar design, allowing free ingress and egress while also restricting airflow. In a manual mantrap, a guard locks and unlocks each door in sequence. An intercom and/or video camera are often used to allow the guard to control the trap from a remote location. In an automatic mantrap, identification may be required for each door, sometimes even different measures for each door. For example, a key may open the first door, but a personal identification number entered on a number pad opens the second. Other methods of opening doors include proximity cards or biometric devices such as fingerprint readers or iris recognition scans. Time of Flight sensors are used in high security environments.

European Standard
European Standards (abbreviated EN, from the German name ("European Norm")) are technical standards which have been ratified by one of the three European standards organizations: European Committee for Standardization (CEN), European Committee for Electrotechnical Standardization (CENELEC), or European Telecommunications Standards Institute (ETSI). All ENs are designed and created by all interested parties through a transparent, open, and consensual process. European Standards are a key component of the Single European Market. They are crucial in facilitating trade and have high visibility among manufacturers inside and outside the European territory. A standard represents a model specification, a technical solution against which a market can trade. European Standards must be transposed into a national standard in all EU member states. This guarantees that a manufacturer has easier access to the market of all these European countries when applying European Standards. Member count ...

Micrometre
The micrometre ( international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is a unit of length in the International System of Units (SI) equalling (SI standard prefix "micro-" = ); that is, one millionth of a metre (or one thousandth of a millimetre, , or about ). The nearest smaller common SI unit is the nanometre, equivalent to one thousandth of a micrometre, one millionth of a millimetre or one billionth of a metre (). The micrometre is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cells and bacteria, and for grading wool by the diameter of the fibres. The width of a single human hair ranges from approximately 20 to . The longest human chromosome, chromosome 1, is approximately in length. Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm – width of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glycol
A diol is a chemical compound containing two hydroxyl groups ( groups). An Aliphatic compound, aliphatic diol is also called a glycol. This pairing of functional groups is pervasive, and many subcategories have been identified. The most common industrial diol is ethylene glycol. Examples of diols in which the hydroxyl functional groups are more widely separated include 1,4-butanediol and 1,3-Propanediol, propylene-1,3-diol, or beta propylene glycol, . Synthesis of classes of diols Geminal diols A geminal diol has two hydroxyl groups bonded to the same atom. These species arise by hydration of the carbonyl compounds. The hydration is usually unfavorable, but a notable exception is formaldehyde which, in water, exists in equilibrium with methanediol H2C(OH)2. Another example is (F3C)2C(OH)2, the hydrated form of hexafluoroacetone. Many gem-diols undergo further condensation to give dimeric and oligomeric derivatives. This reaction applies to glyoxal and related aldehydes. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
