Constrained Differential Renormalization of Yang-Mills Theories

We renormalize QCD to one loop in coordinate space using constrained differential renormalization, and show explicitly that the Slavnov-Taylor identities are preserved by this method.Comment: LaTex, 13 pages with 2 ps figure

Setting up an acupuncture knee clinic under Practice Based Commissioning

Original article can be found at: http://www.acupunctureinmedicine.org.uk/index.shtmlThis paper outlines the setting up of a new service in primary care offering acupuncture to patients with severe osteoarthritis of the knee. The high volume clinic is funded under the Practice Based Commissioning initiative and is the first of its type in the UK. It would appear to offer a model for similar services elsewhere.Peer reviewe

Improved consolidation of silicon carbide

Alpha silicon carbide powder was consolidated by both dry and wet methods. Dry pressing in a double acting steel die yielded sintered test bars with an average flexural strength of 235.6 MPa with a critical flaw size of approximately 100 micro m. An aqueous slurry pressing technique produced sintered test bars with an average flexural strength of 440.8 MPa with a critical flaw size of approximately 25 micro m. Image analysis revealed a reduction in both pore area and pore size distribution in the slurry pressed sintered test bars. The improvements in the slurry pressed material properties are discussed in terms of reduced agglomeration and improved particle packing during consolidation
