The objective of this study was to evaluate the efficiency of different types of sealing on the physical losses of dry matter, chemical and fermentation characteristics and in situ digestibility of the dry matter of corn silage stored in the feed out face (ramp) of trench silos. The experimental design used randomized blocks, composed of three treatments, namely: T1 - corn silage preserved with double-sided polyethylene of 110 μm thickness (conventional seal); T2 - corn silage preserved with double-sided polyethylene of 200 μm thickness (double-sided); and T3 - corn silage preserved with oxygen-impermeable film composed of double-sided polyethylene of 80 μm thickness on a translucent vacuum polyamide film of 20 μm thickness (double sealing), with four repetitions each. The use of double-sided polyethylene with 200 μm thickness (double-sided) and oxygen impermeable film composed of double-sided polyethylene and polyamide (double sealing), were effective in preserving the chemical composition, fermentation profile, raw protein composition and fiber quality, in addition, the use of these polymers resulted in greater ruminal digestibility of dry matter and reduced the pH, temperature, temperature gradient and physical losses of corn silage from the feed out face (ramp) of trench silos compared to the conventional sealing.

Abstract Understanding the adsorption of the smoke stream (SR) on cellulose acetate stick as cigarette filter with different temperatures is beneficial for controlling chemical emissions and reducing the toxic effect of smoking on human health. However the investigation of corresponding adsorption properties was missing because the adsorption of smoke stream (SR) on cigarette cellulose acetate stick is sensitive with the three-dimensional temperature gradient. In this work, the adsorption of typical smoke stream substances, such as CO, propylene glycol, formaldehyde, and acetone, on cellulose acetate stick were studied by in-situ diffuse reflectance Fourier transform infrared spectroscopy with different temperatures assisted by the infrared thermal imaging method. The adsorption capacities of cellulose acetate stick to these typical smoke stream substances is dependent on the adsorption time and temperature. The adsorption properties all fitted well with the Freundlich model. By a spectroscopic and mathematical explanation, quantifying contours of adsorption was performed. The 3D model of the normalized CO adsorption of cellulose acetate stick versus the spatial coordinates and time was established. This study gives unparalleled insight into smoking release characteristics of tobacco filtered by cellulose acetate and regulating cellulose acetate stick for reducing the negative effect of smoke on human health.

Abstract. In this study on temperature gradient metamorphism in snow, we investigate the hypothesis that there exists a favorable crystalline orientation relative to the temperature gradient, giving rise to a faster formation of crystallographic facets. We applied in-situ time-lapse Diffraction Contrast Tomography on a snow sample with a density of 476 kg m−3 subject to a temperature gradient of 52 °C m−1 at mean temperatures in the range between −4.1 °C and −2.1 °C for three days. The orientations of about 900 grains along with their microstructural evolution are followed over time. Faceted crystals appear during the evolution and from the analysis of the material fluxes, we indeed observe higher sublimation-deposition rate for grains with their c-axis in the horizontal plane at the beginning of the metamorphism. This remains the case up to the end of the experiment for what concerns sublimation while the differences vanish for deposition. That latter observation is explained in terms of geometrical interactions between grains.
