Ambrose Channel Pilot Cable
The Ambrose Channel pilot cable, also called the Ambrose Channel leader cable, was a cable laid in Ambrose Channel at the entrance to the Port of New York and New Jersey that provided an audio tone for guiding ships in and out of port at times of low visibility. The cable was laid during 1919 and 1920; it had been removed from the channel and replaced by wireless technology by the end of the 1920s.

AmBX
AmBX (officially stylised amBX) is a technology (originally developed by Philips) for controlling incandescent and white/coloured LED lighting and other compatible peripherals. This allows lighting designers, and entertainment media providers to generate custom designed lighting environments that are triggered by compatible peripherals (such as lights). The patents for the technology are now owned by a United Kingdom company based in Redhill, amBX UK LTD. AmBX licenses the technology to entertainment producers at no charge.

American Petroleum Institute
The American Petroleum Institute (API) is the largest U.S. trade association for the oil and natural gas industry. It claims to represent about 650 corporations involved in production, refinement, distribution, and many other aspects of the petroleum industry. The association describes its mission as to influence public policy in support of a strong, viable U.S. oil and natural gas industry. API's chief functions on behalf of the industry include advocacy, negotiation and lobbying with governmental, legal, and regulatory agencies; research into economic, toxicological, and environmental effects; establishment and certification of industry standards; and education outreach. API both funds and conducts research related to many aspects of the petroleum industry. The current CEO and president is Mike Sommers.

Amin Beiranvand Pour
My scholarly interests range widely, from mineral exploration to environmental issues such as geo-hazard, structural mapping, geothermal and geomorphic and coastal geology investigations. Subsequently, I have conducted several research projects for geological mapping, disaster management and environmental modeling using a variety of satellite remote sensing data such as the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), Landsat Enhanced Thematic Mapper+ (ETM+), Landsat-8, Advanced Land Imager (ALI), Hyperion and Phased Array type L-band Synthetic Aperture Radar (PALSAR) satellite data in arid and semi-arid terrains, Antarctic, Arctic and tropical environments.

Ammonia Emission in Poultry Facilities
Brazil is the largest broiler meat exporter in the world. This important economic activity generates income in different branches of the production chain. However, the decomposition of residues incorporated in the poultry litter generates several gases, among them ammonia. When emitted from the litter to the air, ammonia can cause several damages to animals and man, in addition to being able to convert into a greenhouse gas.

An Appeal to Reason
An Appeal to Reason: A Cool Look at Global Warming is a 2008 book by Nigel Lawson. In it, Lawson argues that global warming is happening, but that the science is far from settled. He opposes the scientific consensus as summarized by the IPCC. He also argues that warming will bring both benefits and negative consequences, and that the impact of these changes will be relatively moderate rather than apocalyptic. The book has been rejected by climatologists, including IPCC authors Jean Palutikof and Robert Watson as unscientific. The book was published in the UK and the USA in 2008. It appeared in Spanish translation the following year, published by Gota a gota, the imprint of the think tank FAES.

Anaerobic Co-Digestion
The anaerobic mono-digestion treatment of organic waste can be challenging due to nutrient imbalances and a lack of microbial diversity. However, anaerobic co-digestion has been shown to effectively address both challenges without the need for additives.

Anaerobic Co-Digestion of Primary Sludge and Biowastes
Primary sludge is a valuable substrate for anaerobic digestion as it contains a higher percentage of fatty acids and lipids compared to secondary sludge, although its carbon-to-nitrogen ratio is relatively low due to its inherent deficiency of carbon. This limiting factor of C/N ratio can be overwhelmed by the co-digestion of primary sludge with organic fractions such as agricultural byproducts and municipal solid wastes. The operating principle of this practice is based on the fact that organic fractions such as agricultural byproducts contain a high percentage of carbon and a low percentage of nitrogen, so the co-digestion of primary sludge with different organic fractions, such as animal manure, agricultural residues, organic fractions of municipal waste, or vegetable residues, may improve the balance of nutrients, provide buffering capacity, adjust the C/N ratio, reduce the concentration of ammonia, and hence its inhibitory effects, and overall promote the process of methanogenesis.

Analysis Method of Heavy Metals in Organic Fertilizers
Heavy metals in organic fertilizers pose a risk to the agricultural ecosystem. The environmental risk of heavy metals depends not only on the total amount but also on the speciation. Hence, more information on heavy metals speciation in organic fertilizers is needed to avoid adverse effect. The speciation information of heavy metals is usually obtained by the single-extraction method and sequential extraction method. Common heavy metals that have received attention include Cu, Zn, Pb, Cd, Cr, Hg and As.
