bstract We investigate four crucial properties for testing and evaluating a moment closure approximation of the FENE dumbbell model for dilute olymer solutions: non-negative configuration distribution function, energy dissipation, accuracy of approximation and computational expense. hrough mathematical analysis, numerical experiments and comparisons with closure model FENE-P and FENE-YDL, we pr...

the high costs of experimental works on the nanocomposites can be reduced through implementation of analytical and numerical studies. to study the effect of impact energy on the nanocomposites, a nanocomposite composedof polyurethane and clay nanoparticles is selected as a case study. the finite element modeling is carried out using the ansys software, and the impact analysis is performed using...

A 76-year-old woman presented with life-limiting claudication in the left leg. Ankle brachial index (ABI) was 1.07/0.63 (right/left). Duplex ultrasound showed a decreased flow pattern of the left popliteal artery with normal flow pattern in the common femoral artery (CFA), and stenosis or occlusion of the left SFA was strongly suspected. Angiography 1 month later showed severe stenosis in the o...

Spectral studies on the interaction of acidic capsular polysaccharide (SPS), isolated from Klebsiella K28, with cationic dye and surfactants have een reported. The polymer induced strong metachromasy (∼100 nm blue shift) in the cyanine dye pinacyanol bromide (PCYB). The SPS consists f d-glucose, d-galactose, d-mannose and d-glucuronic acid (2:1:2:1 molar ratio) in hexasaccharide repeating units...

Biphenyl was successfully degraded by Burkholderia xenovorans LB400, initially described as Pseudomonas sp. LB400, in a solid–liquid wo-phase partitioning bioreactor (TPPB). Solid–liquid TPPBs are comprised of an aqueous, cell containing phase, and a solid polymeric phase hat partitions toxic and/or poorly soluble substrates (in this case biphenyl) based on maintaining a thermodynamic equilibri...
