Blended learning that combines a modular object-oriented dynamic environment (Moodle) with face-to-face teaching was applied to medical statistics course improve outcomes and evaluate the impact factors of students' knowledge, attitudes practices (KAP) relating e-learning. The same real-name questionnaire administered before after intervention. summed scores every part (knowledge, attitude practice) were calculated using entropy method. A mixed linear model fitted SAS PROC MIXED procedure...
This numerical study utilizes a validated Plaxis 3D model calibrated against full-scale field tests to investigate the lateral load-sharing mechanism of pile cap in 3 × group under horizontal loading. Numerical simulations reveal that significantly enhances bearing capacity while reducing displacement by an average 59.5%. The ratio decreases from 62% at low loads 50% higher loads, with corresponding increase contributions. decomposition cap’s resistance identifies passive earth pressure...
Inactivated Enterovirus 71 (EV71) vaccines showed significant efficacy against the diseases associated with EV71 and a neutralizing antibody (NTAb) titer of 1:16-1:32 was suggested as correlates vaccine protection. This paper aims to further estimate immunological surrogate endpoints for protection inactivated effect factors.Pre-vaccination NTAb at baseline (day 0), post-vaccination day 56, occurrence laboratory-confirmed EV71-associated during 24-months follow-up period were collected from...
The existing studies have primarily focused on the effect of cyclic load characteristics (namely, ratio and amplitude ratio) lateral response monopiles in sand, with little attention paid to pile-soil relative stiffness (KR). This paper presents a series 1-g tests aimed at improving understanding responses under different pile—soil systems. These systems are arranged by two model piles stiffness, including four slenderness ratios (pile embedded length, L, normalized diameter, D) medium dense...
Suction caisson foundations are often subjected to vertical uplift loads, but there still no wide and spread engineering specifications on design calculation method for bearing capacity of suction foundation. So it is important establish an failure criterion. In order study the mechanism mode foundation, a series model tests were carried out considering effects aspect ratio, soil permeability loading mode. Test results indicate that residual negative pressure at top beneficial enhance...
Suction caisson foundation derives most of their uplift resistance from passive suction developed during the pullout movement. It was observed that generated in soil at bottom and failure mode subjecting loading behaves as a reverse compression mechanism. The upper bound theorems have been proved to be powerful method find critical mechanism load associated with foundations, buried caissons other geotechnical structures. However, limited attempts reported estimate bearing capacity using...
The mechanical properties of interactive marine-terrestrial (IMT) deposit soils differ from those other deposits as a result the complex sedimentary environments in which they are found. creep behaviors IMT Ningbo, China were studied via triaxial drained testing. theory fractal derivatives was then applied to develop merchant model, dashpot replaces conventional Newtonian dashpot, characterize deposits. model results indicate that Ningbo demonstrate typical nonlinear behaviors. As time and...
Suction caisson foundations can be used to anchor tension leg platforms. The soil at the bottom of undergoes both unloading and cyclic loading under wind wave loads. However, problem cumulative deformation soft clay has rarely been addressed. So, strain softening characteristics are studied by triaxial tests. test results show that low static deviator stress ratios dynamic ratios, a level accumulation softening. As increase, gradually increases, which rapidly develops in early stage tends...
As the anchoring foundation of tension leg platform (TLP), suction caisson is subjected to long-term vertical pullout loads. But there are few studies on mechanism unloading creep soft clay and uplift bearing capacity foundations. To address this problem, tests were carried out analyze strain development with time under different confining pressures. The test results show that curve rapidly develops in early stage tends stabilize later stage. deviator stress higher, deformation greater has...
This paper proposed a simplified calculation method to analyze the cyclic response of large-diameter single piles based on modified strain wedge model. Firstly, pile–soft clay interaction above pile-rotating point is represented by p–y curve, and below rotating an equivalent rotation spring. At same time, stiffness attenuation model describe curve for analyzing bearing characteristics soft clay. Finally, verified two case studies. The results from agree reasonably well with measured results....
An experimental investigation of Isaacs' incompressible unsteady airfoil theory in the context trailing edge flow under an oscillating freestream is presented this work. Elliptical choke vanes were used to generate time-varying velocity Ohio State University Unsteady Transonic Wind Tunnel. Surface pressures on a NACA 0018 integrated provide phase-averaged time history lift coefficient, which compared with theory. The observed effects advance ratio (velocity amplitude) and reduced frequency...
In the process of cyclic loading, strain development not only presents softening phenomenon, but also a hardening depending on different values static deflection stress. The and characteristics soft clay are studied by triaxial tests. test results show that when stress is zero, value cumulative small, phenomenon. When greater than accumulation increases with increasing stress, present Therefore, index were proposed to describe soil. Moreover, an equivalent creep model was established...
