Run II at the Fermilab Tevatron Collider started in March 2001, and it will continue probing the high energy frontier in particle physics until the start of the LHC at CERN. The CDF collaboration at Fermilab has already stored 260 TB of data and expects to store 1PB of data in the next two years. The HEXCAF computing farm is being set up at Rutgers University to provide the software environment...

The number of farm-based biogas plants in Austria increased rapidly in the recent past, a continuing interest in this technology is expected. A survey was carried out in 2002 to provide information for farmers and the decision makers involved. In most plants slurry and manure is co-digestion with energy crops and/or organic waste. Wet fermentation in mesophilic digesters with post-digesters com...

Two epidemiologic studies of risk factors for transmission of Toxoplasma gondii to swine were conducted for farms in Illinois. The first study was a cross-sectional survey of swine farms from the state of Illinois pseudorabies testing program, in which farm owners or managers were interviewed by telephone regarding presence of risk factors for transmission of T. gondii on the farm. There were 1...

Management practices that reduce greenhouse gas emissions from farms or increase on-farm carbon storage can contribute to climate change mitigation. Farmers, however, are only likely to adopt new management practices if they contribute to farm profitability. We use the Agricultural Production Systems sIMulator (APSIM) to simulate how different cropping practices contribute to greenhouse gas aba...

Manure application increases pasture crop production and minimizes manure storage costs. Excess N not absorbed by pasture vegetation can leach past the root zone and into ground water. A yearlong study was conducted on grazing pastures at 2 dairy farms to monitor potential nitrate (NO3) movement from the surface through the soil profile toward ground water. Precipitation, irrigation, manure app...

The distribution and abundance of black flies (Diptera: Simuliidae) in a small desert stream were influenced by environmental changes caused by recharge of water supply storage basins and an aquaculture operation. Simulium virgatum was the most abundant benthic insect collected in Whitewater Canyon (Riverside County, CA) after April; however, it was never found in trout farm effluent where the ...

BACKGROUND A major global challenge is to provide agricultural production systems that are able to sustain growing demands for food, feed, fibre and renewable raw materials without exacerbating climate change. Detailed and reliable data on the CO(2) balance of different agricultural management activities and inputs as a basis to quantify carbon footprints of agriculture are still lacking. This ...

Energy storage is an important resource that can balance fluctuations in energy generation from renewable energy sources, such as wind, to increase their penetration. Many existing storage control methods require perfect information about probability distribution of uncertainties. In practice, however, the distribution of renewable energy production is difficult to reliably estimate. To resolve...

A beef herd submodel was created for integration with other farm components to form a whole-farm model capable of simulating a wide range of beef production systems. This herd submodel determined the best available feed or feed mix to meet the fiber, energy, and protein requirements for each of up to six animal groups on the farm. The groups comprised any combination of cows, nursing calves, yo...

Making farm decisions is difficult, especially making decisions about selling and pricing wheat in deregulated supply chains. This study, conducted prior to export deregulation, sought to identify which factors were important to northern New South Wales (NSW) wheat growers when they were making decisions about wheat selling and price risk, under production and market uncertainty. Key questions ...
