PUTTING ENVIRONMENTAL ACTORS CENTRE STAGE For Strategic Environmental Management Analysis (SEMA), the most crucial role in change towards sustainability is played by “environmental actors” i.e., those who are moved by specific environmental concerns and urge other actors on to change. The strategies they may use, the contexts and conditions in which they may succeed, are considered here to be t...

Many major airports in the U.S. rely on simultaneous approaches to closely-spaced parallel (CSP) runways to maintain a high airport acceptance rate. During Visual Meteorological Conditions (VMC), aircraft are able to utilize both runways by making side-by-side landings and are able to meet the demands of heavy volume. However, when conditions deteriorate to marginalVMC or Instrument Meteorologi...

During the 1970s the building industry witnessed a focus on energy-conserving building materials sparked by oil-price increases; during the 1980s attention to building materials that reduced or omitted pollutants became important as a result of the "Sick Building Syndrome" or indoor air pollution. Now, in the 1990s, we are engaged with a more comprehensive definition of environmental materials ...

A model has been developed to simulate a fixed-exit porous bleed system for supersonic inlets. The fixed-exit model allows the amount of bleed flow to vary according to local flow conditions and fixedexit characteristics of the bleed system. This variation is important for the control of shock-wave/ boundary-layer interactions within the inlet. The model computes the bleed plenum static pressur...

current standards for indoor comfort are based on studies of adults, but they also apply tochildren, even though children differ in terms of metabolic rates, clothing types, activity levels, and preferences in space arrangement. children are also more sensitive to a range of environmental factors, they are usually unable to interact with their environment, and they accept indoor conditions pass...

Breakwaters are the important and the costly ones of the marine structures. Composite breakwater is one of the common types in the world. Because of the sensitivity of composite breakwaters to environmental conditions, also construction costs, difficulty of repair and maintenance and importance of equipments on and behind the breakwater, design of composite breakwater must be very accurate. Goa...

The paper uses Italian official survey data collected in 2012 from more than 20 thousand households to shed light on the determinants of people’s pro-environmental behavior, specifically differentiation domestic waste disposal. A rich interdisciplinary literature has developed explain why people may make eco-friendly choices, which come at a personal cost and provide benefits accruing largely o...

India has large resources of natural fibres such as Banana, Khus, Sisal, Korai grass,Talipot, Palm leaf, Coconut, Pineapple, Screwpine, Golden grass, Jute and Sabaiamong others. In the past, trade of the village folk depended on harvesting fibresgrown in their villages. Natural fibers have recently gaining attraction of researchersdue to their low cost eco-friendly and biodegradability characte...
