Bovine respiratory disease complex (BRDC) is an important cause of mortality and morbidity in cattle; costing the dairy and beef industries millions of dollars annually, despite the use of vaccines and antibiotics. BRDC is caused by one or more of several viruses (bovine respiratory syncytial virus, bovine herpes type 1 also known as infectious bovine(More)
In terms of the quantitative causal principle, 3 this paper obtains a new general variational principle, presents the unified expressions of the new general, Hamilton, Voss, Hölder, Maupertuis-Lagrange variational principles of integral style, and finds the intrinsic relations among the different integral variational principles, it is proved that, under the(More)
Oxygenated volatile organic compounds (OVOCs) are important products of the photo-oxidation of hydrocarbons. They influence the oxidizing capacity and the ozone-forming potential of the atmosphere. In the summer of 2008, 2 months of emission restrictions were enforced in Beijing to improve air quality during the Olympic Games. Observational evidence(More)
