Radioisotope techniques were used to study kinetics of sucrose, glucose, and fructose accumulation in slices of immature sugar�cane tissue. For all three sugars, accumulation rate was P. hyperbolic function of sugar concentration, suggesting intermediate compound formation between the sugars and some receptor or "carrier" in the cell. Sucrose and glucose interacted competitively, implying that, these two sugars (and probably also fructose, fructose 6-phosphate, and glucose I-phosphate) shared the same carrier.

AbstractThe interaction of Al and W in the Si/SiO2/W-Ti/Al thin film system is studied quantitatively by glancing angle x-ray diffraction. The formation of Al-W compounds due to annealing is monitored by the variation of the integrated intensity from a few x-ray diffraction peaks of the corresponding compounds. The annealing was conducted at 400°C, 450°C and 500°C from 1 hour to 300 hours. The kinetics of compound formation is determined using x-ray diffraction data and verified by TEM observations. We will also show the correlation of the compound formation to the change of the electrical properties of these films.

The kinetics of strontium, 85Sr, and cesium, 134Cs, were evaluated in a mouse experimental model to determine the impact of these radionuclides on a living organism concerning total body irradiation. Our study demonstrates that the elimination rate of 134Cs from the skeleton and teeth is influenced by total body irradiation and the presence of 85Sr. Higher accumulation and faster 134Cs elimination rates were observed in the skeleton and teeth of mice administrated with a mixture of 134Cs + 85Sr radionuclides. Regarding 85Sr, only a minimal effect was observed on its accumulation rate in skeleton, teeth, and muscle in total body irradiation mice. The effect of the 85Sr + 134Cs radionuclide mix on the accumulation of 85Sr was more apparent in teeth, showing a higher retention rate after 10-24 days of administration in non-irradiated mice. The evaluation of the kinetics of these radionuclides provided much-needed insight on their effects during the first two months after exposure, demonstrating that the accumulation rate of 85Sr is greater than that of 134Cs. Further, the elimination rate of the former is slower in comparison to the latter. Interestingly, total body irradiation has a greater effect on the hematological parameters of the mice blood than the radionuclides alone.

The objective this study was to evaluate the effect of maniçoba supplementation in sugar cane silage with respect to chemical-bromatological composition and the in vitro degradation kinetics of the silage. This experiment was conducted in a completely randomized design with four treatments (maniçoba levels: 0, 20, 30, and 40%) and six repetitions. Silage samples were analyzed for their chemical-bromatological composition, digestible energy, metabolizable energy, total digestible nutrients, in vitro gas production and degradability parameters. The silage with higher inclusion level had better bromatological composition (p < 0.05) than the silage without maniçoba for CP, NDF, ADF and MM (6.49, 56.64, 38.66 and 4.52% versus 2.21, 70.96, 49.95 and 2.78%). Higher ME content (2.35 MJ kg-1 MS versus 1.85 MJ kg-1 MS), DE (2.87 Mcal kg-1 MS versus 2.25 Mcal kg-1 MS) and TDN (65.16% versus 51.11%), respectively. The highest values for gas production were also observed in silage with added maniçoba due to higher NFC content (34.87%). With an increase in the proportion of maniçoba, there was an increase in the soluble a fraction, b fraction, and thus a higher effective degradability of dry matter (46.56%). The addition of maniçoba improves the nutritive value of sugarcane silage.

The corrosion behavior of pure aluminum (Al) in 20 v/v% ethanol–gasoline blends has been studied using electrochemical techniques. Ethanol was obtained from different fruits including sugar cane, oranges, apples, or mangos, whereas other techniques included lineal polarization resistance, electrochemical noise, and electrochemical impedance spectroscopy for 90 days. Results have shown that corrosion rates for Al in all the blends were higher than that obtained in gasoline. In addition, the highest corrosion rate was obtained in the blend containing ethanol obtained from sugar cane. The corrosion process was under charge transfer control in all blends; however, for some exposure times, it was under the adsorption/desorption control of an intermediate compound. Al was susceptible to a localized, plotting type of corrosion in all blends, but they were bigger in size and in number in the blend containing ethanol obtained from sugar cane.
