ケイシャ オリフィス デ ケイセイ サレル キホウ ノ タイセキ

The bubble formation at the inclined orifices is investigated at the constant pressure system (constant pressure supply). It is found that the gas flow rates, the orifice dimensions, the chamber volumes and the physical properties of liquid affect the bubble volume. In the regions of the low gas flow rates and the small chamber volumes, the bubble volume increases with the inclination of the orifice with respect to the horizontal. The values of critical chamber number, up to which the bubble volume do not depend upon the gas flow rates and the chamber volumes is a function of the orifice diameter and the physical properties of liquid. By the application of Newton\u27s second law of motion, the various forces acting on the surface of bubble are related. This model is examined by the experimental data, and the correlation with respect to the bubble volume is obtained

Air Pollution at Mizushima Industrial Area : Simulation of SO_x Consentration

In this study, it is purpose to establish a forecasting method for conditions of air pollution at a seaside industrial area. Using the data in Mizushima industrial area, we investigated the relation between weather conditions and SO_x concentrations on the ground level. The distributions of SO_x concentration were calculated by the plume model at the weather condition in which this area was polluted. And the optimum parameters for the plume model by which the error between measured and calculated SO_x concentration became smallest were obtained. It was found that the optimum parameters could be correlated by the wind velocity

Data on amyloid precursor protein accumulation, spontaneous physical activity, and motor learning after traumatic brain injury in the triple-transgenic mouse model of Alzheimer׳s disease

This data article contains supporting information regarding the research article entitled “Traumatic brain injury accelerates amyloid-β deposition and impairs spatial learning in the triple-transgenic mouse model of Alzheimer׳s disease” (H. Shishido, Y. Kishimoto, N. Kawai, Y. Toyota, M. Ueno, T. Kubota, Y. Kirino, T. Tamiya, 2016) [1]. Triple-transgenic (3×Tg)-Alzheimer׳s disease (AD) model mice exhibited significantly poorer spatial learning than sham-treated 3×Tg-AD mice 28 days after traumatic brain injury (TBI). Correspondingly, amyloid-β (Aβ) deposition within the hippocampus was significantly greater in 3×Tg-AD mice 28 days after TBI. However, data regarding the short-term and long-term influences of TBI on amyloid precursor protein (APP) accumulation in AD model mice remain limited. Furthermore, there is little data showing whether physical activity and motor learning are affected by TBI in AD model mice. Here, we provide immunocytochemistry data confirming that TBI induces significant increases in APP accumulation in 3×Tg-AD mice at both 7 days and 28 days after TBI. Furthermore, 3×Tg-AD model mice exhibit a reduced ability to acquire conditioned responses (CRs) during delay eyeblink conditioning compared to sham-treated 3×Tg-AD model mice 28 days after TBI. However, physical activity and motor performance are not significantly changed in TBI-treated 3×Tg-AD model mice
