History of Motorola

Motorola started as Galvin developed Corporation in 1928. The name Motorola was adopted in 1947, but the word had been used as a trademark since the 1930s. Founders Paul Galvin and Joe Galvin came up with the name Motorola when his company started manufacturing car radios. A number of early companies making phonographs, radios, and other audio tackle in the early 20th century used the suffix "-ola," the most famous being Victrola; RCA made a "radiola"; there was also a company that made jukeboxes called Rock-Ola, and a film editing device called a Moviola. The Motorola prefix "motor-" was chosen because the company's first focus was in automotive electronics.

Most of Motorola's crop has been radio-related, starting with a battery eliminator for radios, through the first walkie-talkie in the world, defense electronics, cellular infrastructure equipment, and mobile phone manufacturing. The company was also strong in semiconductor technology, including integrated circuits used in computers. Motorola has been the key supplier for the microprocessors used in Commodore Amiga, Apple Macintosh and Power Macintosh personal computers. The chip used in the latter computers, the PowerPC family, was developed with IBM and in a partnership with Apple. Motorola also has a diverse line of communication products, including satellite systems, digital cable boxes and modems.

Fish food

Fish food is plant or animal material intended for consumption by pet fish kept in aquariums or ponds. Fish foods usually contain macro nutrients, trace elements and vitamins necessary to keep captive fish in good health. Approximately 80% of fishkeeping hobbyists feed their fish exclusively prepared foods that most commonly are produced in flake, pellet or tablet form.Pelleted forms, some of which sink rapidly, are often used for larger fish or bottom feeding species such as loaches or catfish. Some fish foods also contain additives, such as beta carotene or sex hormones, to artifically enhance the color of ornamental fish.

Neem oil

Neem oil is a vegetable oil pressed from the fruits and seeds of Neem, an evergreen tree which is endemic to the Indian sub-continent and has been introduced to many other areas in the tropics. It is perhaps the most significant of the commercially available products of neem.Neem oil is typically light to dark brown, bitter and has a rather strong odour that is said to join the odours of peanut and garlic. It comprises mainly triglycerides and large amounts of triterpenoid compounds, which are in charge for the bitter taste. It is hydrophobic in nature and in order to emulisify it in water for application purposes, it must be formulated with suitable surfactants.Neem oil also contains steroids and a plethora of triterpenoids of which Azadirachtin is the most well known and studied. The Azadirachtin content of Neem Oil varies from 300ppm to over 2000ppm depending on the quality of the neem seeds compressed.

Compiler

A compiler is a computer program or set of programs that converts text written in a computer language (the source language) into another computer language (the target language). The original sequence is frequently called the source code and the output called object code. Commonly the output has a form appropriate for processing by other programs (e.g., a linker), but it may be a human-readable text file.

The most common reason for wanting to translate source code is to make an executable program. The name "compiler" is primarily used for programs that convert source code from a high level language to a lower level language (e.g., assembly language or machine language). A program that translates from a low level language to a higher level one is a decompiler. A program that translates between high-level languages is generally called a language translator, source to source translator, or language converter. A language rewriter is generally a program that translates the form of expressions without a modify language.

Krill fishery

Krill fishery is the commercial fishery of krill, small shrimp-like marine animals that live in the oceans world-wide. Estimates for how much krill there is vary wildly, depending on the methodology used. They range from 125–725 million tonnes of biomass globally. The total global harvest of krill from all fisheries amounts to 150 – 200,000 tonnes annually, mainly Antarctic krill (Euphausia superba) and North Pacific krill (E. pacifica).
Krill are rich in protein (40% or more of dry weight) and lipids (about 20% in E. superba). Their exoskeleton amounts to some 2% of dry weight of chitin. They also contain traces of a wide array of hydrolytic enzymes such as proteases, carbohydrases, nucleases and phospholipases, which are intense in the digestive gland in the cephalothorax of the krill.
Most krill is used as aquaculture feed and fish bait; other uses comprise livestock or pet foods. Only a small percentage is prepared for human consumption. Their enzymes are interesting for medical applications, an expanding sector since the early 1990s.
