Personal Protective Equipment
Personal protective equipment (PPE) is protective clothing, helmets, goggles, or other garments or equipment designed to protect the wearer's body from injury or infection. The hazards addressed by protective equipment include physical, electrical, heat, chemical, biohazards, and airborne particulate matter. Protective equipment may be worn for job-related occupational safety and health purposes, as well as for sports and other recreational activities. ''Protective clothing'' is applied to traditional categories of clothing, and ''protective gear'' applies to items such as pads, guards, shields, or masks, and others. PPE suits can be similar in appearance to a cleanroom suit. The purpose of personal protective equipment is to reduce employee exposure to hazards when engineering controls and administrative controls are not feasible or effective to reduce these risks to acceptable levels. PPE is needed when there are hazards present. PPE has the serious limitation that it d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palmoplantar Erythema
Many skin conditions affect the human integumentary system—the organ system covering the entire surface of the Human body, body and composed of Human skin, skin, hair, Nail (anatomy), nails, and related muscle and glands. The major function of this system is as a barrier against the external environment. The skin weighs an average of four kilograms, covers an area of two square metres, and is made of three distinct layers: the epidermis (skin), epidermis, dermis, and subcutaneous tissue. The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin.Burns, Tony; ''et al''. (2006) ''Rook's Textbook of Dermatology CD-ROM''. Wiley-Blackwell. . Within the latter type, the hairs occur in structures called pilosebaceous units, each with hair follicle, sebaceous gland, and associated arrector pili muscle. Embryology, In the embryo, the epidermis, hair, and glands form from the ectod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Ensemble
A climate ensemble involves slightly different models of the climate system. The ensemble average is expected to perform better than individual model runs. There are at least five different types, to be described below. Aims The aim of running an ensemble is usually in order to be able to deal with uncertainties in the system. An ultimate aim may be to produce policy relevant information such as a probability distribution function of different outcomes. This is proving to be very difficult due to a number of problems. These include: #The ensemble has to be wide-ranging to ensure it covers the whole range where the climate models may be good. #Measuring what is a good model is difficult. This may need to consider not only errors in the observation but also in the model. #Any prior assumptions about distribution can influence the probability distribution function produced. Multi-model ensemble Multi-model ensembles (MMEs) are widely used in IPCC assessments, and a comprehensive c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyphenyl Ether
Phenyl ether polymers are a class of polymers that contain a phenoxy or a thiophenoxy group as the repeating group in ether linkages. Commercial phenyl ether polymers belong to two chemical classes: polyphenyl ethers (PPEs) and polyphenylene oxides (PPOs). The phenoxy groups in the former class of polymers do not contain any substituents whereas those in the latter class contain 2 to 4 alkyl groups on the phenyl ring. The structure of an oxygen-containing PPE is provided in Figure 1 and that of a 2, 6-xylenol derived PPO is shown in Figure 2. Either class can have the oxygen atoms attached at various positions around the rings. Structure and synthesis The proper name for a phenyl ether polymer is poly(phenyl ether) or polyphenyl polyether, but the name polyphenyl ether is widely accepted. Polyphenyl ethers (PPEs) are obtained by repeated application of the Ullmann Ether Synthesis: reaction of an alkali-metal phenate with a halogenated benzene catalyzed by copper. P ...

Poly(p-phenylene Oxide)
Poly(''p''-phenylene oxide) (PPO), poly(''p''-phenylene ether) (PPE), poly(oxy-2,6-dimethyl-1,4-phenylene), often referred to simply as polyphenylene oxide, is a high-temperature thermoplastic with the general formula (C8H8O)n. It is rarely used in its pure form due to difficulties in processing. It is mainly used as blend with polystyrene, high impact styrene-butadiene copolymer or polyamide. PPO is a registered trademark of SABIC Innovative Plastics B.V. under which various polyphenylene ether resins are sold. History Polyphenylene ether was discovered in 1959 by Allan Hay, and was commercialized by General Electric in 1960. While it was one of the cheapest high-temperature resistant plastics, processing was difficult, while the impact and heat resistance gradually decreased with time. Mixing it with polystyrene in any ratio could compensate for the disadvantages. In the 1960s, modified PPE came into the market under the trademark Noryl. Properties PPE is an amorphous high-p ...

Volkswagen Group Premium Platform Electric
Premium Platform Electric (PPE) is a modular car platform for electric cars developed by Volkswagen Group brands Audi and Porsche. The platform is meant for larger electric vehicles which are not suitable for the Volkswagen Group MEB platform. Details of the platform were first revealed in 2019, with Audi noting that it would have 60% commonality with the MLB Evo platform. The first car officially announced for PPE was the Audi A6 e-tron. Details The car reportedly has a WLTP range, with an 800V electrical architecture that allows DC fast charging at up to 270kW.

PCBoard
PCBoard (PCB) was a bulletin board system (BBS) application first introduced for DOS in 1983 by Fred Clark's Clark Development Company. PCBoard was one of the first commercial BBS packages for DOS systems, and was considered one of the "high end" packages during the rapid expansion of BBS systems in the early 1990s. PCB was used as the basis of some of the largest bulletin board systems of the era, like Canada Remote Systems. PCB was notable for its support of large multi-line BBS systems, which it supported by running multiple copies of the program, either using Computer multitasking, multitasking systems like DESQview or on multiple physical machines using shared storage. The system was licensed by the number of lines it would support; the majority of the systems were the basic two-line license, but it was also offered in 5, 10, 25, 50, 100, 250 and 1000 line systems. A native 32-bit IBM OS/2 version became also available with PCB V15.22 and higher. There were also a few tools ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
