The Microgravity Science Glovebox (MSG) is a glovebox aboard the International Space Station. It provides a safe contained environment for research with liquids, combustion and hazardous materials in the microgravity conditions of the ISS. Without the MSG, many types of hands-on investigations would be impossible or severely limited on board the Station. The Microgravity Science Glovebox (MSG) occupies a floor-to-ceiling rack inside the Destiny module of the International Space Station (ISS). It is more than twice as large as gloveboxes flown on the Space Shuttle and can hold larger investigations that are about twice the size of an airline carry-on bag.
The Core Facility of MSG occupies the upper half of the overall rack and includes the large work volume (WV), an airlock and electronics for control, housekeeping and investigation resources. The WV holds the experiment and related equipment. The work volume is approximately 3 feet wide (906 mm), 2 feet high (637 mm), and 1.5 feet deep (442 mm) with a usable volume of about 255 litres. This area can be sealed and held at a negative pressure, isolating the crew and the Station from possible hazards associated with the investigations that are taking place inside.
The New Approach to Appraisal (also NATA) was the name given to a multi-criteria decision framework used to appraise transport projects and proposals in the United Kingdom. NATA was built on the well established cost-benefit analysis and environmental impact assessment techniques (such as those contained in the Highways Agency's Design Manual for Roads and Bridges (DMRB)) for assessing transport projects and proposals.
In April 2011 the Coalition Government decided that the term NATA would no longer be used. However, the principles and key elements of the NATA framework remain in the Department for Transport's Webtag Transport Analysis Guidance.
Edinburgh Business School (EBS) is the Graduate School of Business of Heriot-Watt University (est. 1821), Edinburgh, Scotland. Heriot-Watt University is the eighth oldest higher educational institution in the UK, and awards degrees by Royal Charter. There are currently over 10,300 active students studying Edinburgh Business School programmes and more than 14,300 graduates across 150 countries worldwide.
Transport economics is a branch of economics founded in 1959 by American economist John R. Meyer that deals with the allocation of resources within the transport sector. It has strong links to civil engineering. Transport economics differs from some other branches of economics in that the assumption of a spaceless, instantaneous economy does not hold. People and goods flow over networks at certain speeds. Demands peak. Advance ticket purchase is often induced by lower fares. The networks themselves may or may not be competitive. A single trip (the final good, in the consumer's eyes) may require the bundling of services provided by several firms, agencies and modes.
Although transport systems follow the same supply and demand theory as other industries, the complications of network effects and choices between dissimilar goods (e.g. car and bus travel) make estimating the demand for transportation facilities difficult. The development of models to estimate the likely choices between the such goods involved in transport decisions (discrete choice models) led to the development of an important branch of econometrics, as well as a Nobel Prize for Daniel McFadden.
Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells in an effort to produce energy, maintain life, or stimulate growth.
Historically, people secured food through two methods: hunting and gathering, and agriculture. Today, most of the food energy consumed by the world population is supplied by the food industry.
WebTAG refers to the UK Department for Transport's web-based multimodal guidance on appraising transport projects and proposals.
WebTAG reflects the New Approach to Appraisal that was developed in 1998 and initially applied to decisions on trunk road schemes and a series of major multimodal studies. WebTAG was first issued in 2003.
