We developed a method for mass production of rice protein isolate (RPI) and evaluated its nutritional quality in rats. To obtain thick slurry, rice flour was mixed with a 0.6% Termamyl 120L-solution (1:2, w/v) at room temperature (~23°C). The slurry was heated at 97°C for 2 hr with stirring. Gelatinization and liquefaction occurred simultaneously. RPI obtained by filtration and washing with boiling water, was more than 90% pure protein (dry matter basis). It also contained 6.4% dietary fiber, 1.3% ash, and 1.1% carbohydrate. RPI diets (40–50%) allowed the maximum growth in rats comparable to that with 25% casein diet. 相似文献

We simultaneously observed both the fast proton generation and terahertz (THz) radiation in the laser pulse interaction with a thin-foil target.The maximum proton energy of ~2.3 MeV and an intense THz radiation were observed at the pulse duration of ~30fs.We also measured the proton beam and UV harmonics from a thin-foil target by changing the laser pulse duration.In the case of the ~500 fs, peaks of UV harmonics up to fourth order appeared.This unique combination of the multiple beams will provide useful applications such as pump-probe experiments. 相似文献

For the purpose of evaluating the fatigue strength of the Japanese railway wheel, fatigue testing was done on the actual size wheel, using a new resonance‐type fatigue‐testing machine. Because the maximum stress under the horizontal and vertical loads occurs at the wheel plate, the fatigue strengths of the wheel plate were measured and the safety factors versus design load were evaluated. Two kinds of typical Japanese railway wheel were tested and the results showed that their safety factors were larger than 2.4. 相似文献
