사질토의 액상화에 대한 저항 강도는 포화도에 상당히 의존한다. 압축파 속도는 현장에서 쉽게 측정이 가능하고 포화도의 영향을 크게 받기 때문에 현장 지반의 포화도를 예측하고자 할 때 효율적으로 사용될 수 있다. 본 논문에서는 시료의 포화가 가능하고 전단파, 압축파 속도 측정 및 비배수 상태에서 비틂전단 시험을 수행시 유발되는 과잉간극수압을 측정할 수 있는 비틂전단 시험기를 개발하였다. 토요라 모래에 대해 전단파, 압축파 속도 측정이 수행되고, 비배수 비틂전단 시험을 실시하였다. 포화도(B값)에 따른 시료의 전단파... -

the surrounding membranes by fiItrative bulk flow, where the rate of Na+ efflux has a linear relationship with that of water efflux. This is assumed to be carried out through enlarged and newly opened intercellular spaces resulting from increased intraamniotic pressure. 3) Once increasing intraamniotic pressure reaches a point allowing Li+ to pass through during osmotic bulk flow in hypotonic amniotic fIuid, Na+ influx seems to occur by diffusion simultaneously or immediately thereafter, too. -

Carbon fibers (CFs) have a unique combination of properties which allow them to be widely used as reinforcing materials in advanced polymer composites. The mechanical properties of CF-reinforced polymer composites are governed mainly by the quality of interfacial adhesion between the CFs and the polymer matrix. Surface treatments of CFs are generally carried out to introduce chemical functional groups on the fiber surfaces, which provide the ability to control the surface characteristics of CFs.... -

Carbon aerogel is a porous carbon material possessing high porosity and high specific surface area. Nitrogen doping reduced the specific surface area and micropores, but it furnished basic sites to improve the CO2 selectivity. In this work, N-doped carbon aerogels were prepared with different ratios of resorcinol/melamine by using the sol-gel method. The morphological properties were characterized by scanning electron microscopy (SEM). Nitrogen content was studied by X-ray photoelectron...
