Seaport Center
Seaport Centre is a high-tech business park located in Redwood City, California, United States, and as of 2007 is one of the largest biotechnology research complexes in the San Francisco Bay Area. The property consists of of developed building area, and is situated in proximity to the Port of Redwood City. The property is classified as Class A office space and is constructed as a series of separate buildings. The original lands of the Seaport Centre were used as salt evaporation ponds on tidal lands of the San Francisco Bay, a land use that started sometime prior to 1940. As of 2002 leasing rates at Seaport Centre were in the range of $27 per square foot per annum. In 2005, Slough Estates, a United Kingdom-based REIT, purchased the entirety of Seaport Centre to develop it as a biotechnology research center to compete with the existing biotech hubs in Silicon Valley and South San Francisco. The Seaport Centre is located on generally level ground at approximately above mean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Redwood City, California
Redwood City is a city on the San Francisco Peninsula in Northern California's Bay Area, approximately south of San Francisco, and northwest of San Jose. Redwood City's history spans its earliest inhabitation by the Ohlone people to being a port for lumber and other goods. The county seat of San Mateo County in the heart of Silicon Valley, Redwood City is home to several global technology companies including Oracle, Electronic Arts, Evernote, Box, and Informatica.

Surface Runoff
Surface runoff (also known as overland flow) is the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or man-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry man-made contaminants or natural forms of pollution (such as rotting leaves). Man-made contaminants in runoff i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acetone
Acetone (2-propanone or dimethyl ketone), is an organic compound with the formula . It is the simplest and smallest ketone (). It is a colorless, highly volatile and flammable liquid with a characteristic pungent odour. Acetone is miscible with water and serves as an important organic solvent in its own right, in industry, home, and laboratory. About 6.7 million tonnes were produced worldwide in 2010, mainly for use as a solvent and production of methyl methacrylate (and from that PMMA) as well as bisphenol A.Acetone World Petrochemicals report, January 2010Stylianos Sifniades, Alan B.

Organic Chemical
In chemistry, organic compounds are generally any chemical compounds that contain carbon-hydrogen or carbon-carbon bonds. Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. The study of the properties, reactions, and syntheses of organic compounds comprise the discipline known as organic chemistry. For historical reasons, a few classes of carbon-containing compounds (e.g., carbonate salts and cyanide salts), along with a few other exceptions (e.g., carbon dioxide, hydrogen cyanide), are not classified as organic compounds and are considered inorganic. Other than those just named, little consensus exists among chemists on precisely which carbon-containing compounds are excluded, making any rigorous definition of an organic compound elusive. Although organic compounds make up only a small percentage of Earth's crust, they are of central importance because all known life is based on organic compounds. Living thing ...

Solvent
A solvent (s) (from the Latin '' solvō'', "loosen, untie, solve") is a substance that dissolves a solute, resulting in a solution. A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid. Water is a solvent for polar molecules and the most common solvent used by living things; all the ions and proteins in a cell are dissolved in water within the cell. The quantity of solute that can dissolve in a specific volume of solvent varies with temperature. Major uses of solvents are in paints, paint removers, inks, and dry cleaning. Specific uses for organic solvents are in dry cleaning (e.g. tetrachloroethylene); as paint thinners (toluene, turpentine); as nail polish removers and solvents of glue (acetone, methyl acetate, ethyl acetate); in spot removers (hexane, petrol ether); in detergents ( citrus terpenes); and in perfumes (ethanol). Solvents find various applications in chemical, pharmaceutical, oil, and gas industries, including in chemical syn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hazardous Material
Dangerous goods, abbreviated DG, are substances that when transported are a risk to health, safety, property or the environment. Certain dangerous goods that pose risks even when not being transported are known as hazardous materials ( syllabically abbreviated as HAZMAT or hazmat). An example for dangerous goods is hazardous waste which is waste that has substantial or potential threats to public health or the environment. Hazardous materials are often subject to chemical regulations. Hazmat teams are personnel specially trained to handle dangerous goods, which include materials that are radioactive, flammable, explosive, corrosive, oxidizing, asphyxiating, biohazardous, toxic, pathogenic, or allergenic. Also included are physical conditions such as compressed gases and liquids or hot materials, including all goods containing such materials or chemicals, or may have other characteristics that render them hazardous in specific circumstances. Dangerous goods are often indicated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Personics
Personics was the company that invented the music recording retail system with trade name "Personics System" that was introduced in record stores starting in 1987. The system allowed customers to enter a music store, use headphones to preview and select individual songs on a console, then specify a custom list of songs to be recorded to a Compact Cassette tape. The songs available were also listed in magazine format available at the stores. The record stores had a machine from Personics that contained 120 custom Compact discs (2 drives with 60 discs each) recorded in CD Digital Audio Redbook format with custom Dolby AC1 (DP85) tracks which were also pre-encoded with Dolby B Type Noise reduction prior to compression. These two drives each had jukebox disc changing systems and provided access to thousands of songs for fast (8x speed) in-shell cassette recording. Songs and other musical selections could be selected from a variety of artists, record labels, genres, etc. and arranged ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ross Video
Ross Video Ltd is a privately held Canadian company that designs and manufactures equipment for live event and video production. Ross Video's headquarters and manufacturing operations are located in Iroquois, Ontario, Canada, while their R&D labs are in Ottawa, Ontario, Canada. History John Ross, a former engineer with the Canadian Broadcasting Corporation (CBC), founded Ross Video in Iroquois, Ont., in 1974 to make production switchers. Jim Leitch, founder of Leitch Video (acquired by Harris), initially suggested that Ross should start the company. The primary seed funding for the company came from the sale of a Taylorcraft L-2 that John Ross had restored. The company's first generation of switchers was the RVS family. The RVS 16–4, the first switcher made, was followed closely by the RVS 10-4 (a 16–4 with 10 video inputs). The first downstream keyer (DSK) could be added to the 10-4 to allow the addition of more video layers. Ross launched its second generation of swi ...

Cygnus Inc
Cygnus, Inc. was a biotechnology company that dissolved in 2007. At its inception in 1985, Cygnus was engaged in development and manufacturing of transdermal drug delivery systems, including products for contraception, hormone therapy and smoking cessation. The company also developed the GlucoWatch, a non-invasive glucose monitoring devices for manufacture and commercialization. When GlucoWatch was launched in early 2002, the product sales of GlucoWatch were much lower than expected. According to the Company, the reasons for failure included adoption barriers for new technology, need for a paradigm shift in the management of diabetes, lack of widespread medical reimbursement, and performance characteristics of the device. History First, the GlucoWatch faced difficulties in its clinical efficacy and reproducibility of measurements. Cygnus did not resolve these technical feasibility issues and was unable to replace the standard glucose monitoring device that was on the market. Sec ...

Salt
Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in the form of a natural crystalline mineral is known as rock salt or halite. Salt is present in vast quantities in seawater. The open ocean has about of solids per liter of sea water, a salinity of 3.5%. Salt is essential for life in general, and saltiness is one of the basic human tastes. Salt is one of the oldest and most ubiquitous food seasonings, and is known to uniformly improve the taste perception of food, including otherwise unpalatable food. Salting, brining, and pickling are also ancient and important methods of food preservation. Some of the earliest evidence of salt processing dates to around 6,000 BC, when people living in the area of present-day Romania boiled spring water to extract salts; a salt-works in China dates to approximately the same period. Salt was also prized by the ancient Hebrews, Greeks, Romans, Byzantines, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agriculture
Agriculture or farming is the practice of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials (such as rubber). Food classes include cereals (grains), vegetables, fruits, cooking oils, meat, milk, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Salt
Sea salt is salt that is produced by the evaporation of seawater. It is used as a seasoning in foods, cooking, cosmetics and for preserving food. It is also called bay salt, solar salt, or simply salt. Like mined rock salt, production of sea salt has been dated to prehistoric times. Composition Commercially available sea salts on the market today vary widely in their chemical composition. Although the principal component is sodium chloride, the remaining portion can range from less than 0.2 to 10% of other salts. These are mostly calcium, potassium, and magnesium salts of chloride and sulfate with substantially lesser amounts of many trace elements found in natural seawater. Though the composition of commercially available salt may vary, the ionic composition of natural saltwater is relatively constant. Historical production Sea salt is mentioned in the Vinaya Pitaka, a Buddhist scripture compiled in the mid-5th century BC. The principle of production is evaporation of the w ...
