The survival rate of 1674 bridges and the influence of several factors on the lifetime of bridges were analysed, based on data from patient records that belonged to a random sample of 40 Dutch general practices. It appears that the 12 year survival rate of the bridges is 87%. There is a significant difference in the survival rate between the bridges that meet and do not meet Ante's law, and onl...
We report results of a search for B → τν in a sample of 9.7 million charged B meson decays. The search uses both πν and lνν̄ decay modes of the τ , and demands exclusive reconstruction of the companion B̄ decay to suppress background. We set an upper limit on the branching fraction B(B → τν) < 8.4 × 10−4 at 90% confidence level. With slight modification to the analysis we also establish B(B → Kνν̄...
introduction: attention to food safety and health at all stages from production to consumption is inevitable. inappropriate sanitary status of the food production, distribution and supply centers caused food-borne diseases. the aim of this study was to evaluate the environmental health indicators of halva and tahini production centers in the city of ardakan in 2013. materials & methods: this is...
abstract in this study, we synthesized a novel template polymer by using methacrylic acid (mma) as functional monomer, ethylene glycol dimethacrylate(egdma) as cross linker, 2,2-azobisisobutyronitrile (aibn) as initiator and olanzapine as targeted molecule in the presence of chloroform and acetonitrile as solvent. the products have been characterized and confirmed by (chn)elemental analysis,...
