  • Metal foams are a new, as yet imperfectly characterized, class of materials with low densities and novel physical, mechanical, thermal, electrical and acoustic properties. They offer potential for lightweight structures, for energy absorption, and for thermal management; and some of them, at least, are cheap. The current understanding of their production, properties and uses in assembled in this Design Guide.

  • At $13 billion and roughly five percent of the total semiconductor market (2004 data) the power semiconductor market is big and growing fast, typically outgrowing the rest of the semiconductor market. Modern electronic appliances, while exhibiting increasing functionality, are also expected to consume little power, for reasons of portability, thermal performance, and environmental considerations.

  • The inspiration for Building Systems for Interior Designers came when I tried to teach interior design students about all the ways buildings support our activities and physical needs—without an adequate textbook. I needed an approach that supported the special concerns of the interior designer, while connecting those issues to the work of the rest of the building design team.

  • Introduction: Mixed ionic–electronic conductors (MIECs) have been and continue to be of interest for strategic applications related to energy conversion and environmental monitoring including batteries, fuel cells, permeation membranes, and sensors. Within solid oxide fuel cells (SOFCs), for instance, nanostructured ionic and electronic conducting materials can increase the electrochemical performance of the cathode and thus could potentially facilitate lower-temperature operation and thereby provide faster start-up times, improved stability, and less complicated thermal management. ...

  • Ennore Creek becomes the pollution point in Bay of Bengal which influences the marine resources and productivity of the region. This coastal belt in the neighboring areas of the city is viewed as dumping sites for industrial effluents and disposing domestic waste (Arunagiri et al., 1998). The natural wealth of the creek is now being eroded to mere sewage channel (Jayaprakash, 2003). The Ennore Thermal Power Plant uses the river waters as coolant and lets out the warm water, in the Ennore Creek.

  • ADC’s latest addition to its family of outside plant products, the Radiator II Below Ground HDSLx Repeater Housing, is a highly costeffective outside plant enclosure for local loop electronics. With its advanced thermal management capabilities, the Radiator II extends the life of enclosed cards or repeaters and reduces costly truck rolls and maintenance. Radial placement of modular card cages permits efficient and predictable thermal transfer for uniform cooling. In addition, its unique design allows the heat to radiate externally, increasing the reliability of the enclosed electronics....

  • In order to maintain economic development and minimize future regional and international conflicts, the United States will need sustainable supplies of high-quality fresh water. Solutions to local water scarcity issues will likely require a combination of approaches, including demand management, improved water storage capacity, water quality protection, and advancements in supply-enhancing water treatment technologies. Desalination technologies can create new sources of freshwater from otherwise impaired waters such as seawater or brackish water.

  • In some ways, the uncertainty over supply consistency is really a form of risk management. In the future, both petrochemical supply and renewable supply will carry increased risk. For petrochemicals, further supply uncertainty may arise from political changes in other world areas. For plant-derived materials, weather may be an uncertain factor locally, while specialty plants with less commodity type production may result in more trading uncertainty.

  • As network equipment such as routers and switches, continues to evolve, changes in proper cable-management techniques and recommendations must also keep up with the times. Routers and switches are being marketed with higher densities and more capabilities. These higher-density platforms have more cables feeding them and require more power. More powerful equipment gives out more heat, so careful airflow and thermal management is more important than ever. Density within a single cabinet is increasing.

  • Combustion units (process furnaces, steam boilers and gas turbines) give rise to emissions of carbon dioxide, nitrogen oxides, sulphur dioxide and particulates. Nitrogen oxide emissions are most commonly reduced by combustion modifications that reduce temperatures and hence the formation of thermal NOx. The techniques include low NOx burners, flue gas recirculation, and reduced pre-heat. Nitrogen oxides can also be removed after they have formed by reduction to nitrogen using Selective Non Catalytic Reduction (SNCR) or Selective Catalytic Reduction (SCR). Water pollutant control.

  • The specific process employed will depend on factors such as the characteristics and constituents of the potash ore and the market specifications. Generally, the ore is reduced in size using a system of crushing and grinding to liberate the different miner- als from each other. This is usually followed by desliming by intense agitation followed by flotation or hydrocyclones to separate the fines consisting of clays, dolomite and sand from the potash ore.

  • Rapid prototyping is now also seen as an integral part of the even larger but not well defined rapid tooling (RT) market. Concept modeling addresses the early stages of the design process, whereas RT concen- trates on production tooling or mold making. Some concept modeling equipment, also called 3D or office printers, are self-contained desktop or benchtop manufacturing units small enough and inexpensive enough to permit prototype fabrication to be done in an office environment.

  • With an annual human population growth rate of 2.4%, the present 77.4 million Ethiopia’s human population will increase to about 149.3 million by the year 2040 (FAO 2005). The rural to urban ratio will also continue to change and is expected to increase in favour of urban population in the coming 25 years. The current rural and urban distribution of 84.7% and 15.3% will gradually reach 80.1% and 19.9% by the year 2020 (CSA 2008). Vulnerable age groups (up to 14 years) will account for 34% of the population.
