Using the SCUBA instrument on the JCMT, we have made a submillimeter mosaic at 850μm of a subarea of the Spitzer First Look Survey (FLS). Our image covers the central 151 arcmin of the northern extragalactic Continuous Viewing Zone (CVZ) field of the FLS to a median 3σ depth of 9.7 mJy. The image contains ten 850μm sources detected at 3.5σ or higher significance, of which five are detected at ≥...

poly(vinyl acetate) is synthesized via solution polymerization, and then it is converted to poly(vinyl alcohol) by alkaline alcoholysis. the aim of the work study was to investigate statistically the  influence of reaction variables in vinyl acetate polymerization, the conversion of this monomer to polymer, degree of branching of acetyl group in poly(vinyl acetate), as well as the molecular wei...

OBJECTIVE To evaluate the relationship between patients' body mass index (BMI) and the degree of radiographic severity of knee osteoarthrosis. METHOD 117 patients with gonarthrosis were evaluated prospectively. The patients' BMI was calculated and their knee arthrosis was classified in accordance with the modified Ahlbäck criteria. Kruskal-Wallis analysis of variance (ANOVA) was used to evalu...
