Pulmonary arterial hypertension (PAH) is a progressive disease characterized by vascular remodeling of pulmonary arteries (PAs) and increased vascular resistance in the lung. Monocrotaline (MCT), a toxic alkaloid, is widely used for developing rat models of PAH caused by injury to pulmonary endothelial cells; however, characteristics of vascular functions in MCT-induced PAH vary and are not fully understood. Here, we investigated hypoxic pulmonary vasoconstriction (HPV) responses and effects of... -
Effect of the surface modification using MWCNTs with different L/D by two different methods of deposition on the IFSS of single carbon fiber-epoxy resin composite

surface morphology after the MWCNT deposition were analyzed using SEM, which revealed a higher density and uniform coverage for the PAMAM-treated CF and the short MWCNTs. The interfacial adhesion of the composite materials was evaluated using the single fiber fragmentation technique. The results indicated an improvement in the interfacial shear strength with the addition of the short-MWCNTs treated with acid solutions and grafted onto the surface of the CF fiber using electrostatic attraction. -

병렬전단벽시스템은 경제적이고 효율적인 구조시스템이지만, 연결보의 복잡한 철근상세가 요구된다. 이를 보완하고자 ACI-318에서는 개선된 철근상세를 제안하고 있지만 과도한 횡보강근으로 현장 적용에 어려움이 따른다. 이 연구에서는 횡보강 철근량을 감소시킨 대각철근을 갖는 HPFRCC 연결보 상세를 제안하고, 형상비 2.0 실험체를 통해 현행 기준에 만족하는 대각철근을 갖는 철근콘크리트 연결보와 이력거동을 비교 평가하였다. 그 결과, HPFRCC의 횡구속 효과를 확인하였고, 횡구속 철근을 기준의 1/2로 배근하고 HPFRCC로 보강한...
