Polyurethane/zeolite 13X nanocomposite films were fabricated using solution casting method. The synthesized nanocomposite films were structurally characterized using SEM, TGA and tensile analysis. SEM images showed appropriate distribution of nanocrystalline zeolite particles within polyurethane matrix. Better thermal stability of nanocomposite films in comparison to neat polyurethane was shown...

The breaking stress (the maximum of the stress–strain curve) of neutron star crust is important for neutron star physics including pulsar glitches, emission of gravitational waves from static mountains and flares from star quakes. We perform many molecular dynamic simulations of the breaking stress at different coupling parameters (inverse temperatures) and strain rates. We describe our results...

this study was conducted to evaluate the bioavailability of nano and micro sources of manganese in broiler chickens. two hundred and eight, 10-d-old male ross 308 broilers in a completely randomized design with 13 treatments, 4 replications and 4 chicks per replicate were studied for 35 days. during the experimental period, a basal corn-soybean meal diet containing 20 ppm mn (control treatment)...

In this paper, a new camera based lumber strength classification solution using solely knot features is presented. Two alternative classifiers, k-NN and SVM, are applied to classifing pinewood boards based on their breaking strength. Features for classification are formed using knot properties, which are extracted from four sides of the board using machine vision algorithms. Extracted propertie...

The effects of type 2 diabetes mellitus (T2DM) on bone volumetric density, bone geometry, and estimates of bone strength are not well established. We used peripheral quantitative computed tomography (pQCT) to compare tibial and radial bone volumetric density (vBMD, mg/cm(3)), total (ToA, mm(2)) and cortical (CoA, mm(2)) bone area and estimates of bone compressive and bending strength in a subse...

BACKGROUND Skeletal loading and proper nutrition are necessary for optimal bone health. The appropriate amount of dietary protein to maximize skeletal health, however, is under constant debate. OBJECTIVE To determine if 6 months of protein supplementation in conjunction with a strength and conditioning training program improves areal and volumetric bone mineral density (BMD). DESIGN Fifty-t...
