GC: n CT: Which Energy Source is Best? It depends. Many alternative sources of energy are still being researched and tested. Technologies are continually being developed and enhanced to improve energy sources. Not all energies are ready for mass consumption, so you have to ask the right questions to find
GC: n CT: Energy storage — a key technology for global energy sustainability. The quality of life today is dependent upon access to a bountiful supply of cheap energy. For a sustainable future, the energy should be derived from non-fossil sources; ideally, it should also be reliable and safe, flexible
CG: n CT: Energy transition refers to the global energy sector’s shift from fossil-based systems of energy production and consumption — including oil, natural gas and coal — to renewable energy sources like wind and solar, as well as lithium-ion batteries. The increasing penetration of renewable energy into the energy
GC: n CT: Before its use in a reactor, uranium must undergo four processing steps to convert it from an ore to solid ceramic fuel pellets. These processes are: mining and milling, conversion, enrichment and fabrication. Mining and Milling Uranium miners use several techniques to obtain uranium: surface (open pit),
GC: n CT: Thermodynamics is a branch of physics which deals with the energy and work of a system. Thermodynamics deals only with the large scale response of a system which we can observe and measure in experiments. In aerodynamics, we are most interested in thermodynamics in the study of
GC: n CT: The government is working to protect our environment by reducing pollution, reducing the amount of waste sent to landfill, protecting areas of parkland, wildlife reserves and marine biodiversity, and enforcing regulations that kecep our water and air clean. We also help communities avoid or recover from flooding
GC: n CT: According to some EPA guidelines due to the importance of accurate cost information in making the decisions sketched out above, the term “environmental cost” has been introduced into the vocabulary of environmental managers. Today we are starting a series of posts related to the definition(s) and the
GC: n CT: Environmental Impact Assessment. One of the EPA’s key roles is to provide Government with advice on the environmental acceptability of development proposals and statutory planning schemes. Development proposals include proposals for mining, industry as well as infrastructure such as ports, railways and pipelines. Planning schemes include both
GC: n CT: Although some researchers believe that environmental sensitivities may have strictly psychological origins, a 1994 review of psychological studies found methodological and logical problems in the then current psychological research. Environmental sensitivity reactions to inhalation challenges may mimic panic disorder, which is classified as a psychiatric condition. However,
GC: n CT: Environmental sustainability involves making decisions and taking action that are in the interests of protecting the natural world, with particular emphasis on preserving the capability of the environment to support human life. It is an important topic at the present time, as people are realising the full
GC: n CT: Biotechnological approaches to reduce or modify lignin in biomass crops are predicated on the assumption that it is the principal determinant of the recalcitrance of biomass to enzymatic digestion for biofuels production. We defined quantitative trait loci (QTL) in the Intermated B73 x Mo17 (IBM) recombinant inbred
GC: n CT: Given the multifactorial etiology for MSD and its association with individual and workplace risk factors, their reduction and prevention will require a multidisciplinary effort. The science of ergonomics, biomechanics, epidemiology, and medicine are being used to better understand the interdependence of MSD. Ergonomics (Greek ergon = work
GC: n CT: Ethanol is an alternative fuel produced from starch contained in grains such as corn, grain sorghum, barley and sugarcane through a fermentation and distillation process that converts starch to sugar and then to alcohol (ethanol). Most ethanol in the U.S. is made from corn because it is
GC: n CT: Eutrophication is characterized by excessive plant and algal growth due to the increased availability of one or more limiting growth factors needed for photosynthesis (Schindler 2006), such as sunlight, carbon dioxide, and nutrient fertilizers. Eutrophication occurs naturally over centuries as lakes age and are filled in with
GC: adj CT: The minimum amount of runoff that must be preserved in order to maintain basin salt balance is conceptually calculated. The alternative, the conversion of all runoff into evapotranspiration, is unsustainable, because it will cause salts to accumulate without limit. Nature intended exorheic drainage basins to be in
GC: n CT: Paralyzed from the waist down after a BMX accident, Steven Sanchez rolled into SuitX’s Berkeley, California, office in a wheelchair. A half-hour later he was standing and walking thanks to the Phoenix—a robotic exoskeleton now available for around $40,000. The suit returns movement to wearers’ hips and
GC: n CT: An expansion tank is a metal tank connected to a building’s water heating appliance designed to accommodate fluctuations in the volume of a building’s hot water supply system. These fluctuations occur because water expands in volume as it gets hot and loses volume as it cools. Expanding
GC: n CT: Expert Systems are computer programs that are derived from a branch of computer science research called Artificial Intelligence (AI). AI’s scientific goal is to understand intelligence by building computer programs that exhibit intelligent behavior. It is concerned with the concepts and methods of symbolic inference, or reasoning,
