Class B (baseball)
Minor League Baseball (MiLB) is a professional baseball organization below Major League Baseball (MLB), constituted of teams affiliated with MLB clubs. It was founded on September 5, 1901, in response to the growing dominance of the National League (baseball), National League and American League, as the National Association of Professional Baseball Leagues (NAPBL or NA). Minor League Baseball originated as simply the organization of lower tiers of professional baseball in the United States, comprising clubs that lacked the financial means to compete with the National League and later the American League. The association of minor leagues remained independent throughout the early 20th century, protected by agreements with the major leagues to ensure they were compensated when minor-league players were signed by major-league clubs. Later, Minor League Baseball evolved to be constituted entirely of farm team, affiliates of larger clubs, giving young prospects a chance to develop the ...

Power Amplifier Classes
In electronics, power amplifier classes are letter symbols applied to different power amplifier types. The class gives a broad indication of an amplifier's efficiency, linearity and other characteristics. Broadly, as you go up the alphabet, the amplifiers become more efficient but less linear, and the reduced linearity is dealt with through other means. The first classes, A, AB, B, and C, are related to the time period that the active amplifier device is passing current, expressed as a fraction of the period of a signal waveform applied to the input. This metric is known as conduction angle (\theta). A class-A amplifier is conducting through the entire period of the signal (\theta=360°); class-B only for one-half the input period (\theta=180°), class-C for much less than half the input period (\theta 180°); each one of the two active elements conducts more than half of the time. Class-AB is widely considered a good compromise for amplifiers, since many types of input signal are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Boat
A boat is a watercraft of a large range of types and sizes, but generally smaller than a ship, which is distinguished by its larger size or capacity, its shape, or its ability to carry boats. Small boats are typically used on inland waterways such as rivers and lakes, or in protected coastal areas. However, some boats (such as whaleboats) were intended for offshore use. In modern Navy, naval terms, a boat is a vessel small enough to be carried aboard a ship. Boats vary in proportion and construction methods with their intended purpose, available materials, or local traditions. Canoes have been used since prehistoric times and remain in use throughout the world for transportation, fishing, and sport. Fishing boats vary widely in style partly to match local conditions. Pleasure boat, Pleasure craft used in boating, recreational boating include ski boats, Pontoon (boat), pontoon boats, and sailboats. House boats may be used for vacationing or long-term residence. Lighter (barge), L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Campervan
A campervan, also referred to as a camper, caravanette, motorhome or Recreational vehicle, RV (recreational vehicle) in North America, is a self-propelled vehicle that provides both transport and sleeping accommodation. The term describes vans that have been fitted out, whereas a motorhome is one with a coachbuilding, coachbuilt body. Ambiguity with motorhome The term motorhome is sometimes used interchangeably with campervan, but the former can also be a larger vehicle than a campervan and intended to be more comfortable, whilst the latter is more concerned with ease of movement and lower cost. For example, some campervans lack built-in toilets and showers, or a divide between the living compartment and the cab. The United States term "recreational vehicle" (RV) is more analogous to motorhome than campervan. Features Campervans may be equipped either with a "pop-up" roof which is raised during camping, or a fixed roof, either shared with the commercial van that forms the ...

Biosolids
Biosolids are solid organic matter recovered from a sewage treatment process and used as fertilizer. In the past, it was common for farmers to use animal manure to improve their soil fertility. In the 1920s, the farming community began also to use sewage sludge from local wastewater treatment plants. Scientific research over many years has confirmed that these biosolids contain similar nutrients to those in animal manures. Biosolids that are used as fertilizer in farming are usually treated to help to prevent disease-causing pathogens from spreading to the public. Some sewage sludge can not qualify as biosolids due to persistent, bioaccumulative and toxic chemicals, radionuclides, and heavy metals at levels sufficient to contaminate soil and water when applied to land. Terminology Biosolids may be defined as organic wastewater solids that can be reused after suitable sewage sludge treatment processes leading to sludge stabilization, such as anaerobic digestion and composti ...

Classful Network
A classful network is an obsolete network addressing architecture used in the Internet from 1981 until the introduction of Classless Inter-Domain Routing (CIDR) in 1993. The method divides the IP address space for Internet Protocol version 4 (IPv4) into five address classes based on the leading four address bits. Classes A, B, and C provide unicast addresses for networks of three different network sizes. Class D is for multicast networking and the class E address range is reserved for future or experimental purposes. Since its discontinuation, remnants of classful network concepts have remained in practice only in limited scope in the default configuration parameters of some network software and hardware components, most notably in the default configuration of subnet masks. Background In the original address definition, the most significant eight bits of the 32-bit IPv4 address was the ''network number'' field which specified the particular network a host was attached to. ...

Fireworks Policy In The United States
Fireworks policy in the United States can be different in each jurisdiction. Classifications The United States government has classified fireworks and similar devices according to their potential hazards. Current explosives classes The U.S. government now uses the United Nations explosives shipping classification system, which is based on hazard in shipping only, while the old US system also covered use hazards. The BATFE and most states performed a direct substitution of Shipping Class 1.3 for Class B, and Shipping Class 1.4 for Class C. This allows some hazardous items that would have previously been classified as Class B and regulated to be classified as Shipping Class 1.4 due to some packaging method that confines any explosion to the package. Being Shipping Class 1.4, they can now be sold to the general public and are unregulated by the BATFE. A code number and suffix (such as 1.3G) is not enough to fully describe a material and how it is regulated, especially in Shi ...
