Gloves
A glove is a garment covering the hand. Gloves usually have separate sheaths or openings for each finger and the thumb. If there is an opening but no (or a short) covering sheath for each finger they are called fingerless gloves. Fingerless gloves having one small opening rather than individual openings for each finger are sometimes called gauntlets, though gauntlets are not necessarily fingerless. Gloves which cover the entire hand or fist but do not have separate finger openings or sheaths are called mittens. Mittens are warmer than other styles of gloves made of the same material because fingers maintain their warmth better when they are in contact with each other; reduced surface area reduces heat loss. A hybrid of glove and mitten contains open-ended sheaths for the four fingers (as in a fingerless glove, but not the thumb) and an additional compartment encapsulating the four fingers. This compartment can be lifted off the fingers and folded back to allow the individual fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glove Prints
Glove prints, also sometimes described as gloveprints or glove marks, are latent, fingerprint-like impressions that are transferred to a surface or object by an individual who is wearing gloves. Many criminals often wear gloves to avoid leaving fingerprints, which makes the crime investigation more difficult. Although the gloves act as a protective covering for the wearer's prints, the gloves themselves can leave prints that are sometimes unique like human fingerprints, thus betraying the wearer. After collecting glove prints, law enforcement can then match them to gloves that they have collected as evidence as well as glove prints retrieved from other crime scenes. History Since the advent of fingerprint detection, many criminals have resorted to the wearing of gloves during the commission of their crimes in order to avoid leaving their fingerprints as evidence. In the era prior to contemporary advances in forensic science, the simple act of covering the hands often assured crim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cycling Glove
Cycling gloves are gloves designed for cycling. They may provide warmth, comfort and protection. Basic functionality Warmth Gloves are frequently used to keep the hands warm, a function that is particularly necessary when cycling in cold weather. The design of most modern bicycles is such that the rider's hands remain on the handlebars while cycling, a position that leaves them exposed to weather. The hands are also relatively inactive, and do not have a great deal of muscle mass, which also contributes to the possibility of chill. Gloves are therefore vital for insulating the hands from cold, wind, and evaporative cooling while riding a bicycle. Grip In warm weather, sweat from cyclists' hands can cause difficulty maintaining control over the bicycle by making handlebars slippery and difficult to hold without increased hand tension (which can cause further issues and numbness). Cycling gloves, some designed without full finger covering and with ventilation to reduce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gauntlet (glove)
A gauntlet is a variety of glove, particularly one having been constructed of hardened leather or metal plates which protected the hand and wrist of a combatant in Europe between the early fourteenth century and the Early Modern period. Today it can also refer to an extended cuff covering the forearm as part of a woman's garment. Types Armour Beginning in the 11th century, European soldiers and knights relied on chain mail for protection of their bodies, and chain armor "shirts" with wide sleeves that hung to the elbow were common. However, it wasn't until the 12th century that chain mail shirts with longer, narrower sleeves began to be worn, and these on occasion had chain mail mittens or "muffs" resembling fingerless gloves and with a pocket for the thumb (though some of these did have complete fingers as well). These attached at the lower edge of the sleeve, and protected the wearer's hands from cuts and lacerations during combat but offered no protection against cru ...

Inchoate Offense
An inchoate offense, preliminary crime, inchoate crime or incomplete crime is a crime of preparing for or seeking to commit another crime. The most common example of an inchoate offense is "attempt". "Inchoate offense" has been defined as the following: "Conduct deemed criminal without actual harm being done, provided that the harm that would have occurred is one the law tries to prevent."See lists and chapters of texts at McCord and McCord, ''Infra,'' pp. 185-213, and Schmalleger, ''Infra'', pp. 105-161, 404. Intent Every inchoate crime or offense must have the ''mens rea'' of intent or of recklessness, typically intent. Absent a specific law, an inchoate offense requires that the defendant have the specific intent to commit the underlying crime. For example, for a defendant to be guilty of the inchoate crime of solicitation of murder, he or she must have intended for a person to die. Attempt, conspiracy, and solicitation all require ''mens rea''. On the other hand, committ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mail (armour)
Chain mail (properly called mail or maille but usually called chain mail or chainmail) is a type of armour consisting of small metal rings linked together in a pattern to form a mesh. It was in common military use between the 3rd century BC and the 16th century AD in Europe, and longer in Asia and North Africa. A coat of this armour is often called a hauberk, and sometimes a byrnie. History The earliest examples of surviving mail were found in the Carpathian Basin at a burial in Horný Jatov, Slovakia dated at 3rd century BC, and in a chieftain's burial located in Ciumești, Romania. Its invention is commonly credited to the Celts, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cigarette
A cigarette is a narrow cylinder containing a combustible material, typically tobacco, that is rolled into thin paper for smoking. The cigarette is ignited at one end, causing it to smolder; the resulting smoke is orally inhaled via the opposite end. Cigarette smoking is the most common method of tobacco consumption. The term ''cigarette'', as commonly used, refers to a tobacco cigarette, but the word is sometimes used to refer to other substances, such as a cannabis cigarette or an herbal cigarette. A cigarette is distinguished from a cigar by its usually smaller size, use of processed leaf, and paper wrapping, which is typically white. Since the 1920s, scientists and doctors have been able to link smoking with respiratory illness. Researchers have identified negative health effects from smoking cigarettes such as cancer, chronic obstructive pulmonary disease (COPD), heart disease, and other health problems relating to nearly every organ of the body.

Pressure Suit
A pressure suit is a protective suit worn by high-altitude pilots who may fly at altitudes where the air pressure is too low for an unprotected person to survive, even breathing pure oxygen at positive pressure. Such suits may be either full-pressure (e.g., a space suit) or partial-pressure (as used by aircrew). Partial-pressure suits work by providing mechanical counter-pressure to assist breathing at altitude. Background The region from sea level to around is known as the physiological-efficient zone. Oxygen levels are usually high enough for humans to function without supplemental oxygen and decompression sickness is rare. The physiological-deficient zone extends from to about . There is an increased risk of problems such as hypoxia, trapped-gas dysbarism (where gas trapped in the body expands), and evolved-gas dysbarism (where dissolved gases such as nitrogen may form in the tissues, i.e. decompression sickness). Above approximately oxygen-rich breathing mixture is req ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kevlar
Kevlar (para-aramid) is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora. Developed by Stephanie Kwolek at DuPont in 1965, the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires. It is typically spun into ropes or fabric sheets that can be used as such, or as an ingredient in composite material components. Kevlar has many applications, ranging from bicycle tires and racing sails to bulletproof vests, all due to its high tensile strength-to-weight ratio; by this measure it is five times stronger than steel. It is also used to make modern marching drumheads that withstand high impact; and for mooring lines and other underwater applications. A similar fiber called Twaron with the same chemical structure was developed by Akzo in the 1970s; commercial production started in 1986, and Twaron is now manufactured by Teijin.

Neoprene
Neoprene (also polychloroprene) is a family of synthetic rubbers that are produced by polymerization of chloroprene.Werner Obrecht, Jean-Pierre Lambert, Michael Happ, Christiane Oppenheimer-Stix, John Dunn and Ralf Krüger "Rubber, 4. Emulsion Rubbers" in Ullmann's Encyclopedia of Industrial Chemistry, 2012, Wiley-VCH, Weinheim. Neoprene exhibits good chemical stability and maintains flexibility over a wide temperature range. Neoprene is sold either as solid rubber or in latex form and is used in a wide variety of commercial applications, such as laptop sleeves, orthopaedic braces (wrist, knee, etc.), electrical insulation, liquid and sheet-applied elastomeric membranes or flashings, and automotive fan belts. Production Neoprene is produced by free-radical polymerization of chloroprene. In commercial production, this polymer is prepared by free radical emulsion polymerization. Polymerization is initiated using potassium persulfate. Bifunctional nucleophiles, metal oxides (e.g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latex
Latex is an emulsion (stable dispersion) of polymer microparticles in water. Latexes are found in nature, but synthetic latexes are common as well. In nature, latex is found as a milky fluid found in 10% of all flowering plants (angiosperms). It is a complex emulsion that coagulates on exposure to air, consisting of proteins, alkaloids, starches, sugars, oils, tannins, resins, and gums. It is usually exuded after tissue injury. In most plants, latex is white, but some have yellow, orange, or scarlet latex. Since the 17th century, latex has been used as a term for the fluid substance in plants, deriving from the Latin word for "liquid". It serves mainly as defense against herbivorous insects. Latex is not to be confused with plant sap; it is a distinct substance, separately produced, and with different functions. The word latex is also used to refer to natural latex rubber, particularly non-vulcanized rubber. Such is the case in products like latex gloves, latex condoms ...

Felt
Felt is a textile material that is produced by matting, condensing and pressing fibers together. Felt can be made of natural fibers such as wool or animal fur, or from synthetic fibers such as petroleum-based acrylic or acrylonitrile or wood pulp–based rayon. Blended fibers are also common. Natural fibre felt has special properties that allow it to be used for a wide variety of purposes. "It is fire-retardant and self-extinguishing; it dampens vibration and absorbs sound; and it can hold large amounts of fluid without feeling wet..." History Felt from wool is one of the oldest known textiles. Many cultures have legends as to the origins of felt making. Sumerian legend claims that the secret of feltmaking was discovered by Urnamman of Lagash. The story of Saint Clement and Saint Christopher relates that the men packed their sandals with wool to prevent blisters while fleeing from persecution. At the end of their journey, the movement and sweat had turned the wool into f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
