  • 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.

  • East and Southern Europe), India, parts of South America, Southwest U.S./northern Mexico and Australia. The operating characteristics of STPPs are relatively well matched with the intermediate and peak electricity load requirements in these regions. Two types of collectors have been used in STPPs: parabolic trough and central receiver. Electricity is generated by incorporating the solar collectors with a Rankine cycle power plant or as an add-on to a natural gas combined cycle (referred to as an ISCCS).

  • The Rectisol process uses methanol as wash solvent. The methanol has many benefits, is globally available and is a low-cost washing agent. Furthermore, methanol is chemically and thermally stable and will not change its behavior and structure over a long service life. The Rectisol wash unit operates at temperatures below 0°C. To lower the feed gas temperatures, it is cooled against cold-product streams before entering the absorber tower. At the absorber tower, CO2 and H2S/COS are removed.

  • The design and manufacture of transformers is not cutting edge technology, and compared with many fi elds of engineering, progress is slow and change is gradual. The question might therefore be asked as to what is the need for a new and revised edition of The J & P Transformer Book. It is also true that in many branches of the industry the book has become well known and widely respected, and many owners will not consider replacing their trusted old edition. Indeed, many transformer engineers swear by copies handed down to them from older colleagues.

  • The story of metal casting is as glamorous as it is ancient, beginning with the dawn of human civilization and interwoven with legends of fantastic weapons and exquisite artworks made of precious metals. It was and is involved in the two main activities of humans since they began walking the earth: producing and defending wealth. Civilization as we know it would not have been possible without metal casting. Metal casting must have emerged from the darkness of antiquity first as magic, later to evolve as an art, then as a technology, and finally as a complex, interdisciplinary science....
