Diffusion coefficients of a broad range of molécules with molecular weight ranging from 100 to 800 g/mol hâve been measured in polypropylene, by solid/solid contact methods (without liquid contact), at 40°C. The behaviors of thé différent molécules are compared to those of linear alkanes. The diffusion coefficients are correlated to parameters describing size, shape, and flexibility of thé molé...

A cDNA from the putative ovarian tumor (otu) locus of the Drosophila melanoqaster X-chromosome was isolated from a Canton S ovary library using a genomic probe. The otu gene is essential for female fertility, and produces a variety of ovarian phenotypes when mutant (1). The cDNA corresponds tc an abundant 3.2 kb message present in nurse cells and the developing oocyte (2,3). A 2433 b.p. open re...

We present, for both minkowskian and euclidean signatures, short derivations of the diagonal Einstein metrics for Bianchi type II, III and V. For the first two cases we show the integrability of the geodesic flow while for the third case a somewhat unusual bifurcation phenomenon takes place: for minkowskian signature elliptic functions are essential in the metric while for euclidean signature o...

An unwanted signal, known as noise, is added to speech and degrades the quality of signal. There are many speech enhancement techniques used for noise suppression such as spectral subtraction, wiener filtering, decision directed method etc. In this paper, we study some speech enhancem...

OBJECTIVE Store operated calcium channels (SOCCs) and Receptor-operated calcium channels (ROCCs) are important pathways participating in regulation of intracellular Ca(2 +) concentration in various cell types. The purpose of our study is to determine whether genetic variations in key components of SOCCs and ROCCs are associated with lung cancer risk. METHODS We identified 236 tagSNPs in 9 key...

CONTEXT Screening of autoimmune thyroid disease in children and young adults with Type 1 diabetes is important but vary greatly between clinics. OBJECTIVE The aim was to determine the predictive value of thyroid autoantibodies, thyroid function, islet autoantibodies, and HLA- DQ at diagnosis of Type 1 diabetes for autoimmune thyroid disease during subsequent follow-up. SETTING 43 Paediatric...

a symmetrical morphology in which the dorsal and ventral lobes of the tail fin are the same size and project posteriorly beyond the axis of the vertebral column. In contrast, most elasmobranch fishes and some primitive actinopterygian fishes possess a heterocercal caudal fin with an asymmetrical morphology in which the ventral lobe of the fin is smaller than the dorsal lobe and the vertebral co...
