Overview Submicron solid particles are dispersed through interstellar gas. These interstellar grains absorb and scatter light, thus shielding some regions from ultraviolet radiation, but also limiting our ability to detect photons which have been emitted by astronomical objects. Dust grains reradiate absorbed energy in the in-frared, thus contributing to the overall emission spectrum of astrono...

Abstract. Mineral dust is a major light-absorbing aerosol, which can significantly reduce snow albedo and accelerate snow/glacier melting via wet dry deposition on snow. In this study, three scenarios of internal mixing in ice grains were analyzed theoretically by combining asymptotic radiative transfer theory (core–shell) Mie to evaluate the effects absorption coefficient semi-infinite snowpac...

Dietary guidance universally supports the importance of grains in the diet. The United States Department of Agriculture pyramid suggests that Americans consume from six to 11 servings of grains per day, with three of these servings being whole grain products. Whole grain contains the bran, germ and endosperm, while refined grain includes only endosperm. Both refined and whole grains can be fort...

An experiment was conducted using male Ross×Ross 708 broiler chicks to determine the effect of oil extraction from corn distillers dried grains with solubles on apparent ileal amino acid digestibility from 23 to 31 d of age. On an as-fed basis, ether extract concentrations were determined as 5.4% (L-distillers dried grains with solubles), 7.9% (M-distillers dried grains with solubles), and 10.5...

Whole grains are rich in nutrients and antioxidants can be fermented to increase their biological functions. This study used two fermentation steps ferment eight whole grains. The bio-functional compounds, ACE inhibition, antioxidant capacity were measured during the second step. results indicate that total phenols content increased by 2605%, flavonoid 1707%, ABTS radical scavenging 239%, DPPH ...

Liu D., Li Y., Zhang G., Zhang P., Wu P., Wang S., Wang X. (2017): Effect of protein secondary structures in mixed feedstuff detected by Fourier transform infrared spectroscopy on ruminal protein degradation kinetics. Czech J. Anim. Sci., 62, 89–97. The objective of this study was to investigate the relationship between the protein secondary structure and the protein rumen degradation kinetics ...

We show that, when a mixture of small and large grains is simply poured in a g̀ranular Hele± Shaw cell’ (two transparent slabs separated by a gap of about 5mm), the grains spontaneously stratify in alternating layers of small and large grains parallel to the surface of the pile. The spontaneous self-strati® cation occurs only when the large grains have a larger angle of repose than the small gra...

OBJECTIVE This experiment was conducted to determine the effects of dietary β-mannanase on the additivity of true metabolizable energy (TME) and nitrogen-corrected true metabolizable energy (TMEn) for broiler diets. METHODS A total of 144 21-day-old broilers were randomly allotted to 12 dietary treatments with 6 replicates. Five treatments consisted of 5 ingredients of corn, wheat, soybean me...
