in this paper, productivity of and demand for water throughout eqlid’s sugar beet growers in 1385 were investigated. to address the objective 100 growers were selected using two-stage cluster sampling, then required dataset was obtained by interviewing and completing questionnaire. in order to study factors affecting sugar beet production, cobb-douglas production function was applied. based on ...

Hydrogenotrophic methanogens are an intriguing group of microorganisms from the domain Archaea. Methanogens exhibit extraordinary ecological, biochemical, and physiological characteristics and possess a huge biotechnological potential. Yet, the only possibility to assess the methane (CH4) production potential of hydrogenotrophic methanogens is to apply gas chromatographic quantification of CH4....

Forest harvest residues are important raw materials for bioenergy in regions practicing forestry. Removing these residues from a harvest site reduces the carbon stock of the forest compared with conventional stem-only harvest because less litter in left on the site. The indirect carbon dioxide (CO2) emission from producing bioenergy occur when carbon in the logging residues is emitted into the ...

Twenty-four patients with aplastic anemia or acute leukemia were treated by marrow grafts from HLA-identical donors after conditioning with high doses of cyclophosphamide and/or total body irradiation. They were studied between 4 and 63 mo (median 14.2) after transplantation. Seventeen patients had chronic graft-versus-host disease (C-GVHD) and 7 were healthy. They were studied for defects in t...

Leukotrienes are novel mediators derived from arachidonic acid through the 5-lipoxygenase enzyme system. Leukotriene B4 has potent effects on leukocyte function and in vivo induces leukocyte accumulation and changes in vascular permeability and modulates pain responses. Peptido-lipid leukotrienes are potent smooth muscle--contracting agents. They may have important cardiovascular actions throug...

The importance of ‘‘broader” economic effects of transportation infrastructure has recently become apparent. ‘‘Broader” refers to impacts beyond the geographic boundaries within which the infrastructure investments are undertaken. Approaches to estimate ‘‘broader” impacts in production and cost function models are evaluated. A contribution of this paper is the empirical demonstration with a cro...

Child Labor and Schooling Response to Changes in Coca Production in Rural Peru Coca eradication and interdiction are the most common policies aimed at reducing the production and distribution of cocaine in the Andes, but little is known about their impact on households. This paper uses the shift in the production of coca leaves from Peru to Colombia in 1995 to analyze the indirect effects of th...
