The organometallic tris-cyclopentadienide actinide(III) (AnCp3 ) complexes were first reported about 50 years ago. However, up until now, only the NpCp3 solid state structure has been studied. Here we report on the solid state structures of UCp3 and PuCp3 which are isostructural to the Np analogue. The structural models are supported by theoretical calculations and compared to their lanthanide ...

mehredjan bentonite deposit is located ~33 km southeast of khoor in isfehan province. it includes 15 discrete outcrops and occurs as layered and massive forms within a volcano-clastic sequence. bentonitization process was accompanied with development of minerals such as montmorillonite, quartz, cristobalite, calcite, kaolinite, halite, albite, orthoclase, and muscovite. the collected field and ...

abstract poultry manure contains considerable nutrients and its application to agricultural land may boost soil fertility. in order to study the effects of poultry manure and its incorporation method with soil on soil chemical properties, a field experiment was conducted at the ecological research center of zagroos, 30 kms from northeastern of khorramabad for two consecutive years (2004 and 200...

To compare endogenous cholesterol biosynthesis measured by deuterium incorporation (DI) and mass isotopomer distribution analysis (MIDA), cholesterol fractional and absolute synthetic rates were measured simultaneously by both techniques under identical physiological conditions. Twelve subjects (22 to 39 years of age) underwent a dual stable isotope protocol, involving oral deuterium oxide admi...

Averaged across crop, year and season , residue cover reduction was significantly less for coulter-type applicators than for disk-type applica-tors (P<0.001), disk-type applicators reduced residue cover significantly less than chisel and sweep injectors (P<0.001), and chisel and sweep injec-tors reduced residue cover similar to a tandem disk (P=0.398). Ranges of values to estimate the percentag...

Patients with cirrhosis of the liver can develop gastric or gastroesophageal varices, which can bleed and become life threatening Gastric varices pose unique management challenges, as endoscopic therapies are limited Balloon-occluded retrograde transvenous obliteration (BRTO) is a treatment option for gastric varice at high risk of bleeding The BRTO is recommended for patients with gastrorenal ...
