Farm animal welfare has been gradually recognized as an important issue in most parts of the world. In China, domestic animals were traditionally raised in backyard and treated as an important component of family wealth. Industrialization of animal production brings forth the farm animal welfare concerns recently in China, yet the modern concept of animal welfare has not been publicized and a c...
This paper evaluates the comparative performance of emission and standards in a one-stage game abatement R&D Cournot duopoly, terms propensity, output social welfare. For each standard, firms simultaneously select levels, given standard’s exogenous constraint. A standard generates higher investments output, but lower profit, than pollution-equivalent emissions standard. The same conclusion exte...
some new water-soluble schiff base complexes of na2[m(5-so3-1,2-salophen)].nh2o; (5-so3-1,2-salophen = n,n’-bis(5-sulphosalicyliden)-1,2-phenylendiamine); na2[m(5-so3-2,3-salpyr)(h2o)n].2h2o; (5-so3-2,3-salpyr = n,n’-bis(5-sulphosalicyliden)-2,3-diaminopyridine); and na2[m(5-so3-3,4-salbenz)(h2o)n].nh2o; (5-so3-3,4-salbenz = n,n’-bis(5-sulphosalicyliden)-3,4-diaminobenzophenon); where m = cu, n...
investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Due to increased awareness of animal welfare issues by consumers, 3 voluntary programs were developed to assess animal welfare on commercial dairies in the United States. These programs include: 1) Humane Farm Animal Care (HFAC), with minimum standards and a third-party audit system; 2) Dairy Quality Assurance Center (DQAC); and 3) University of California-Davis (UCD) program with self-assessme...
