  • Some reciprocating open-type compressors used with water cooled systems incorporate a cylinder head cooling feature in the form of a water circuit through the compressor head. Supply water enters this before entering the condenser (see Figure 16). A rapid indicating thermometer is recommended for taking water temper- atures because the water regulating valve responds to the operating head pressure and will vary the temperature of the water as it modulates. It is also necessary, when adjusting the water regulator, to be able to take inlet and outlet temperatures quickly.

  • Forests are an integral part of global sustainable development. The World Bank estimates more than 1.6 billion people to be dependent on forests for their livelihoods with some 300 million living in them. The forest product industry is a source of economic growth and employment, with global forest products traded internationally is estimated at $327 billion.

  • Move gates to 10 percent open as measured at the scale on the servomotors and check to see if the gate position needle indicates 10 percent. If the gate position needle does not indicate 10 percent, move the eccentric adjustment in the restoring shaft bell crank to position it correctly (photograph 3). Move it toward the restoring shaft if there is over travel and away from the restoring shaft if there is under travel (figure 7). Move the gates to 90 percent, as measured at the servomotor scale, and check the gate position indicator needle. It may...

  • Although the Standard & Poor's 500 is the most commonly used measure of the performance of the U. S. stock market, it is sometimes argued that, because this index is so heavily populated with high quality, large capitalization stocks, it may not be an appropriate benchmark with which to compare a mutual fund which may be invested in lower quality, smaller capitalization stocks. The obvious refutation: If one can obtain a higher return by investing in...

  • Over the past few years, there has been a fundamental shift in data storage, management, and processing. Companies are storing more data from more sources in more formats than ever before. This isn’t just about being a “data packrat” but rather building products, features, and intelligence predicated on knowing more about the world (where the world can be users, searches, machine logs, or whatever is relevant to an organization).

  • Besides conducting national censuses, the CBS is a primary source of information for multi-sectoral data in the country. It was in the early nineties that the CBS established a separate Household Survey Section (HSS). This section initiated four small-scale surveys with funding from the GoN. Then a comprehensive survey for Nepal was launched by the CBS in 1995/96 through its multi-topic (consumption, income, housing, labor markets, education, health etc.) national household survey called the Nepal Living Standards Survey (NLSS I) with financial assistance from the World Bank.

  • There are four major categories of catastrophic failure which exists in the boiler itself. 1. Melt down. This is a result of the heating surface metal reaching its melting point. It is a result of the boiler operating on very low water conditions. This by itself will not cause an explosion but will do major damage to the boiler and create a dangerous situation which could lead to an explosion.

  • The expansion of agriculture to open access forest lands is a major environmental consequence of poverty, food insecurity, and landlessness in many countries, notably in the tropics. Although nominally managed by the state, forests made accessible by the construction of roads become de facto “open access” in the wake of logging operations by private concessionaires, who often fail to comply with their obligations to manage the forest sustainably after harvest.

  • In addition, the distributions of deaths by age and by cause in Delhi are very different from those in the U.S. In the U.S., over 70 percent of all deaths occur after the age of 65.

  • Whether mode choice yields expected impacts on daily activity level remains an open question. Available research confirms declining activity levels for children (Dietz and Gortmaker, 2001; Trost et al, 2002) and adolescents (Sallis, et al, 2000). However, studies evaluating the role of walking to school have been mixed in finding statistically significant increases in children's daily activity level (Krizek et al, 2004).

  • What is most needed is to adjust the requirements of SEA and EIA directives. The logical order of these assessments should be ensured, as should the respect of the results of SEA in subsequent EIA procedures. Repeated assessment (on the same level of details) shall be avoided, whereas at the same time the availability of information from earlier relevant SEA procedures should be ensured in subsequent EIA procedures.

  • A few studies have provided information on longitudinal trends in VOC concentrations and emissions in new houses (Lindstrom et al., 1995, Hodgson et al., 2002). In four manufactured houses, the area specific emission rates of formaldehyde and hexanal were generally similar at the beginning and end of the 7.5-month study period demonstrating that the sources of these compounds were not depleted rapidly (Hodgson et al., 2000).
