Lower-extremity injury is common in soccer. A number of studies have begun to assess why specific lower-extremity injuries occur. However, currently few studies have examined how footwear affects lower-extremity mechanics. In order to address this question, 14 male (age: 22.1 ± 3.9 years, height: 1.77 ± 0.06 m, and mass: 73.3 ± 11.5 kg) and 14 female (age: 22.8 ± 3.1 years, height: 1.68 ± 0.07 ...
Coal body is a type of fractured rock mass in which lots of cleat fractures developed. Its mechanical properties vary with the parametric variation of coal rock block, face cleat and butt cleat. Based on the linear elastic theory and displacement equivalent principle and simplifying the face cleat and butt cleat as multi-bank penetrating and intermittent cracks, the model was established to cal...
the present study focuses on the performance of precast concrete beam-column dowel connections subjected to cyclic loading by conducting experiments. in this study, one-third scale model of two types of precast and a monolithic beam-column connection were cast and tested under reverse cyclic loading. the precast connections considered for this study is a beam-column connection where beam is con...
The paper presents a methodology for determining the volume of batch conveyed material located before transverse partition certain height and distance over which extends on working surface conveyor belt along its longitudinal axis. Knowing geometric dimensions transported makes it possible to appropriately set spacing cleats thereby optimally determine conveying performance inclined conveyor. W...
AbstractTwo test series were carried out on angle cleat connections between cold-formed channels as beams and rectangular hollow sections support members. The objective of the tests was to deter...
Cold-formed steel (CFS) unlipped channel sections are commonly used as bearers in floor systems while rectangular hollow (RHS) joists. The transverse loads from the joists do not pass through shear centre of due to different joist bearer and column connections. Hence, subjected torsion addition concentrated bending. This study investigated effects two (bolted/welded) connections, (cap plate/ang...
Studies have shown that, coal seam, an un-conventional reservoir, is considered as a promising option for CO2 sequestration because of its large CO2 sequestration capacity, long time CO2 trapping and extra enhanced coal-bed methane (ECBM) production benefits. However, unlike conventional reservoirs, gas flow in the coal seam can cause the cleat permeability and porosity change during the inject...
Many coal seams contain coalbed methane (CBM) yet most of the world’s production comes from the San Juan Basin in the United States. In fact CBM production from this basin of about 0.9 tcf/yr accounts for about 80% of the CBM production in the US (1.2 tcf/yr) and about 60% of world production. Success in the San Juan Basin is not because of increased gas content in the coals compared to coals i...
