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, chemicals, biological hazard, biohazards, and Atmospheric particulate matter, airborne particulate matter. Protective equipment may be worn for job-related occupational safety and health purposes, as well as for sports and other recreation, 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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palmoplantar Erythema
Chemotherapy-induced acral erythema, also known as palmar-plantar erythrodysesthesia or hand-foot syndrome is reddening, swelling, numbness and desquamation (skin sloughing or peeling) on palms of the hands and soles of the feet (and, occasionally, on the knees, elbows, and elsewhere) that can occur after chemotherapy in patients with cancer. Hand-foot syndrome is also rarely seen in sickle-cell disease. These skin changes usually are well demarcated. Acral erythema typically disappears within a few weeks after discontinuation of the offending drug.James, William; Berger, Timothy; Elston, Dirk (2005). ''Andrews' Diseases of the Skin: Clinical Dermatology''. (10th ed.). Saunders. . Signs and symptoms The symptoms can occur anywhere between days to months after administration of the offending medication, depending on the dose and speed of administration. The patient first experiences tingling and/or numbness of the palms and soles. This is followed 2-4 days later by bright redn ...

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. PPE ...

Poly(p-phenylene Oxide)
Poly(''p''-phenylene oxide) (PPO), poly(''p''-phenylene ether) (PPE), often referred to simply as polyphenylene oxide, is a high-temperature thermoplastic. 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 IP 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-performance plastic. The glass transition temperature is 215 °C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power And Propulsion Element
The Power and Propulsion Element (PPE), previously known as the Asteroid Redirect Vehicle propulsion system, is a planned solar electric ion propulsion module being developed by Maxar Technologies for NASA. It is one of the major components of the Gateway. The PPE will allow access to the entire lunar surface and a wide range of lunar orbits and double as a space tug for visiting craft. The PPE originally started development at the Jet Propulsion Laboratory as a part of the now cancelled Asteroid Redirect Mission, but is now led and managed by the NASA John H. Glenn Research Center, in Cleveland, Ohio. When ARM was cancelled, the solar electric propulsion was repurposed as the PPE for the Gateway. The PPE is designed to be able to transfer the reusable Gateway to lunar orbit. It will also serve as the communications center of the Gateway. The PPE is intended to have a mass of 8–9 tons and the capability to generate 50 kW of solar electric power using Roll Out Sola ...

Volkswagen Group Premium Platform Electric
Premium Platform Electric (PPE) is a modular car platform for electric cars being developed by Volkswagen Group brands Audi and Porsche. The platform will be for larger electric vehicles which are not suitable for the Volkswagen Group MEB platform, although Audi will also build cars with the smaller platform. Details of the platform were first revealed in 2019, with Audi noting that it would have 2/3 assembling 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. In November 2022, it was revealed that the architecture allowed rear or four-wheel drive, with power up to 450kW. The batteries run at 800V, but can split into 2 400V packs for further charging.

PCBoard
PCBoard (PCB) was a bulletin board system (BBS) application first introduced for DOS in 1983 by Clark Development Company. Clark Development was founded by Fred Clark. 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. Like many BBS companies, the rise of the Internet starting around 1994 led to serious downturns in fortunes, and Clark Development went bankrupt in 1997. Most PCB sales were of two-line licenses; additional line licenses (in ranges of 5, 10, 25, 50, 100, 250 and 1000) were also available. A native 32-bit IBM OS/2 version became also available with PCB V15.22 and higher. There were also a few tools available for PCBoard, which were specifically developed for the OS/2 2.0 and OS/2 Warp operating system. Multinode support PCBoard supported the 16C550 UARTs ( universal asynchronous receiver transmitter), such as 16550 UART ("Fifo"), 1655 ...
