Anaerobic digestion on a dairy farm: overview


, : Anaerobic digestion on a dairy farm: overview. Energy in Agriculture 4(4): 347-363

The design, implementation and performance of an on-farm plug flow anaerobic digestion system are described. Capital costs for the digester and justifications for certain design decisions are presented. Seasonal variation in the total and volatile solids concentrations, ammonia and organic nitrogen contents, and pH are documented. Biogas outflow of 400-495 msuperscript 3/d was documented for an 180-cow herd.

Coronary artery bypass surgery (CABG) is associated with a significant risk of stroke. Some studies suggest that off-pump CABG (OPCAB) may reduce postoperative stroke rate. We performed this study to evaluate the relationship between postoperative...

In this study, we analyzed the expression of messenger (m)RNAs for laminin B1 chain, alpha 1 (IV) chain of type IV collagen, and 72-kd type IV collagenase in 15 primary lung carcinomas and in two metastatic adenocarcinomas to the lung. The results...
