We examined the effects of feeding water-soluble soybean fiber (WSSF), a highly fermentable dietary fiber, on gastrectomy-induced iron malabsorption, anemia and impairment of exercise performance in rats in two separate experiments. The study was designed as a 2 2 factorial arrangement with operation (total gastrectomy) and diet (WSSF) under sedentary (Experiment 1) and exercised (Experiment 2)...

Broadening the absorption bandwidth of polymer solar cells by incorporating multiple absorber donors into the bulk-heterojunction active layer is an attractive means of resolving the narrow absorption of organic semiconductors. However, this leads to a much more complicated system, and previous efforts have met with only limited success. Here, several dual-donor and multi-donor bulk-heterojunct...

a mathematical model of a continuous reheating furnace has been developed to identify the design and operating parameters that significantly affect furnace performance. in this study, the furnace is modeled 3 dimensionally and themonte carlomethod is used to find the overall absorption factor. the overall absorption factor is then used to calculate the energy balance for furnace walls, the gas,...

A dynamic model of a single-effect absorption refrigeration cycle has been developed. Modeling of the cycle performance requires thermodynamic properties which are obtained from equations of state for refrigerant-absorbent mixtures. The transient response of the absorption refrigeration cycle is investigated using mass, momentum and energy balances for the different parts of the system. Some de...

Electro-absorption from GeSi heterostructures is receiving growing attention as a high performance optical modulator for short distance optical interconnects. Ge incorporation with Si allows strong modulation mechanism using the Franz-Keldysh effect and the quantum-confined Stark effect from bulk and quantum well structures at telecommunication wavelengths. In this review, we discuss the curren...

Due to recent breakthroughs, silicon photonics is now the most active discipline within the field of integrated optics and, at the same time, a present reality with commercial products available on the market. Silicon photodiodes are excellent detectors at visible wavelengths, but the development of high-performance photodetectors on silicon CMOS platforms at wavelengths of interest for telecom...

A theoretical method based on mutual radiation impedance is proposed to compute the sound absorption performance of a Helmholtz resonator array in the low-frequency range. Any configuration of resonator arrangement can be allowed in the method, while all the resonators may or may not be identical. Comparisons of the theoretical predictions with those done by the past studies or experiments show...

Monoclinic-scheelite BiVO4 has been widely studied as a promising oxygen evolution reaction (OER) catalyst in artificial photosynthesis. Though significant progress to improve or augment its catalysis performance has been made, fundamental understanding of its relatively poor performance as a bare material is lacking. In this paper, we report the correlation of the surface structure and trap st...

Low nutritive value and suitability of barley as a feedstuff for broilers is mainly due to its non-starch polysaccharides. An experiment was carried out to evaluate if diets high in barley alter the mechanisms responsible for the absorption of nutrients across the intestinal epithelium of broilers, using D-xylose absorption test. Thirty, 14-d old male broiler chicks (Ross 308) with similar body...

Up to now, the production of the cold is undertaking mainly by the classical way of compression refrigerator cycle. The cycle need an electrical power or mechanics expense for the training of the compressor and the C.F.C for their functioning. Most of the C.F.C impoverish the layer of ozone and participate with a considerable manner, to the increase of the sere effect, then to climatic changes....
