A downscaling method of the microwave surface soil moisture is applied to the PBMR data collected during the Monsoon ’90 experiment. The downscaling method requires (1) the coarse resolution microwave observation (2) the distribution at fine scale of soil temperature and (3) the distribution at fine scale of the surface conditions composed of atmospheric forcing and the parameters involved in t...

of concern about the health and environmental effects of burning fossil fuels such as coal and oil to produce electrical energy in recent years, there has been a resurgence of interest in nuclear power stations as a " carbon-free " method of generating electricity. For example, an interdisciplinary study titled The Future of Nuclear Energy, released by the Massachusetts Institute of Technology ...

The paper presents the main results of the insights to a gas cooled reactor from the perspective of the following notions: probability, uncertainty, entropy and risk. Some results of the ongoing comparisons between the insights obtained from three models are presented. The approaches consider the PBMR nuclear power plant (NPP) as a thermodynamic installation and as a hierarchical system with or...

The Bush Administration has made the expansion of nuclear power generation a centerpiece of its domestic energy policy. However, the White House has not addressed the practical issue of how to overcome the nearly three-decade-long aversion among U.S. electric utilities to investing in new nuclear plants. In today's deregulating market, utilities will not build new nuclear power plants unless th...

Camel calves’ in pastoral production system are constrained by limited milk feeding. Their survival is important for camel herd growth and availability the keepers. A seventy (70) days feeding trial was conducted to determine nutritive value, dry matter intake, weight gain, feed conversion ratio (FCR), apparent digestibility coefficients 15 growing calves with a body of 102.3 ±1.3 Kg (mean ± SE...
