As the living standards of Chinese people have been improving, the energy demand for cooling and heating, mainly in the form of electricity, has also expanded. Since an integrated cooling, heating and power supply system (CCHP) will serve this demand better, the government is now attaching more importance to the application of CCHP energy systems. Based on the characteristics of the combined co...

Approximately 350 million tons of manure is produced annually by agriculture in the U.S. Manure disposal at large concentrated animal feeding operations presents a challenge. Anaerobic digestion of livestock manure to reduce odor and produce biogas for energy generation is a profitable waste management option on farms, but out of reach of most farmers because of high capital costs. For operatio...

Concentrated sources of dairy manure represent significant water pollution potential. The southern United States may be more vulnerable to water quality problems than some other regions because of climate, typical farm size, and cropping practices. Dairy manure can be an effective source of plant nutrients and large quantities of nutrients can be recycled through forage production, especially w...

undoubtly it can be said that climate and how weather conditions effect on building shape including limited architecture elements which has been noticed at the beginning of making shelter by human beings and the principle of this need has not been changed by passing time and changing the styles and movements and definitions of art and beauty and changing needs and attitudes and expanding archit...

Dewes, 1992; Rao Bhamidimarri and Pandey, 1996; Eghball et al., 1997; Tiquia et al., 2002). Swine (Sus scrofa L.) production in deep-bedded hoop structures Field trials comparing composted with fresh dairy is a relatively new swine finishing system in which manure can be applied to fields fresh or after composting. We conducted field-plot manures have shown similar corn yield (Brinton, 1985; tr...

The two-part objective of this study was to determine currently available H2S removal technologies suitable for use with farm biogas systems, and to test the feasibility of utilizing on-farm cow-manure compost as an H2S adsorption medium. Integrated farm energy systems utilize anaerobic digesters to provide a waste treatment solution, improved nutrient recovery, and energy generation potential ...

• Manure application limits impact farmer economic outcomes and probability of runoff. Nitrogen limit takes least amount time, but diminishes value manure. Annual phosphorus costs farmers time money; increases Phosphorus banking maximizes income decreases Three manure – nitrogen limit, annual multiple-year (P Banking) are modeled to compare profitability prior a runoff causing rainfall event. P...
