GC: n CT: The Global Positioning System (GPS) is a satellite-based system that can be used to locate positions anywhere on the earth. Operated by the U.S. Department of Defense (DoD), NAVSTAR (NAVigation Satellite Timing and Ranging) GPS provides continuous (24 hours/day), real-time, 3-dimensional positioning, navigation and timing worldwide. Any
GC: n CT: Landmark analysis released by Greenpeace USA, European Renewable Energy Council (EREC) and other climate and energy advocates shows that the United States can indeed address global warming without relying on nuclear power or so-called “clean coal” — as some in the ongoing energy debate claim. The new
GC: n CT: In the dual water heat exchanger solution, the useful heat is distributed via a hydraulic circuit (glycol water in the outside loops and water in the coils embedded in the floor).In addition to the compressor and the expansion valve, the generator housing includes two exchangers where the
GC: n CT: The significance of slope or gradient. 17. In simple cases, you can assume that the bottom of the canal will slope downstream. In fact, water will flow in canals as long as the water level is higher at the upstream end than the downstream end. If a
GC: n CT: If you’ve ever drawn with a pencil, you’ve probably made graphene. The world’s thinnest material is set to revolutionise almost every part of everyday life. Fascination with this material stems from its remarkable physical properties and the potential applications these properties offer for the future. Although scientists
GC: n CT: Gravimetry is that branch of applied geophysics dealing with the mass distribution within the earth. Gravity surveys make use of the fact that different geological units posses different densities (weight per unit mass) being the basic physical parameter of this method. The fundamental physical law behind this
GC: n CT: What Are Green Certificates (RECs)? The electricity from all power plants, such as coal, nuclear, natural-gas fired, wind, or solar, and whether in a regulated or competitive market, is mixed together in the transmission and distribution lines that deliver electricity to homes and businesses. Meters measure how
GC: n CT: Buildings constructed today are very different from those built 100 years ago. As interest in protecting the environment grows, “green,” or sustainable, buildings have become more commonplace. At first glance, these buildings might not appear very different from their predecessors, but they feature specialized designs and materials
GC: n CT: What is the green economy? The green economy is defined as a sustainable economy and society with zero carbon emissions and a one-planet footprint where all energy is derived from renewable resources which are naturally replenished. A green economy rigorously applies the triple bottom line of people,
GC: n CT: Green energy is defined as energy generated from renewable resources through licensable and environmentally and socially responsible developments. … Green energy generation results in low or no emissions of greenhouse gases, sulphur oxides and local air pollutants. S: TERMIUMPLUS (BC Hydro – http://www.bchydro.com) N: 1. green (adj):
GC: n CT: These practices include equipment acquisition, use, disposal, and related processes. GAO was asked to (1) determine the extent to which the government has defined policy and guidance on green IT and how selected federal agencies are implementing this policy and guidance, and (2) identify leading green IT
GC: n CT: Green power can be procured several different ways. The main distinction among the options is the type of supplier and where the electricity generation equipment is located: on the electric grid or at the facility. For electricity delivered over the power grid, the status of utility restructuring
GC: n CT: There is evidence to suggest that not all corporate tax teams are fully aware of the landscape of green tax in which they operate and the incentives that may be on offer. For example, in March 2012, Bloomberg BNA surveyed tax accountants and tax lawyers in the
GC: n CT: The concept of green and blue water is relatively new1. When precipitation reaches land, it takes either green or blue water pathways. The water that is stored in the unsaturated soil layer forms the green water resource and the water that is stored in the rivers, streams,
GC: n CT: The greenhouse effect refers to circumstances where the short wavelengths of visible light from the sun pass through a transparent medium and are absorbed, but the longer wavelengths of the infrared re-radiation from the heated objects are unable to pass through that medium. The trapping of the
GC: n CT: A greenhouse gas is any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere. By increasing the heat in the atmosphere, greenhouse gases are responsible for the greenhouse effect, which ultimately leads to global warming. S:
GC: n CT: Grey energy is the energy hidden in a product, i.e. the amount of energy required to extract that product from nature, or to cultivate, manufacture, package and transport it. Objects can conceal very different levels of grey energy: for example an apple that is grown locally or
GC: n CT: How greywater systems work. Unlike a rainwater harvesting system, which relies on rainfall, greywater is in plentiful supply on a daily basis – the more clean water that you use to wash yourself, your food and your dishes, the more greywater you will have to recycle. But
GC: n CT: Grit chambers are basin to remove the inorganic particles to prevent damage to the pumps, and to prevent their accumulation in sludge digestors. Grit chambers are of two types: mechanically cleaned and manually cleaned. In mechanically cleaned grit chamber, scraper blades collect the grit settled on the
CG: n CT: A GFCI is only as good as its installation and inspection. A ground-fault circuit interrupter (GFCI) is the only protection device designed to protect people against electric shock from an electrical system. Because of this, we need to understand what a GFCI is, how it works, and
GC: CT: Grout Hole Drilling: Drill grout holes with standard rotary or percussion drilling equipment. No core recovery will be required and the type bit used shall be optional with the Contractor. The hole shall be of sufficient diameter to allow use of an expansion plug or packer with an
