A secondary seeding precision double-seed peanut hole seed metering device was designed to improve the performance of planting equipment and provide a solution for problems on high charge that can cause poor cavitation uniformity easily. The main structure operation parameters in terms groove length, height, seed-bed belt speed, rotation speed wheel were determined through theoretical analysis....

Initial strength gains were examined in the context of learning a new skill. Forty female volunteers were randomly assigned to one of four groups: a bench-press training group utilizing heavy loads in its training, a bench-press training group utilizing almost no load, an alternative training group using different exercises, or a control group that did not train. Training period was 6 wk, with ...

The aim of this study was to compare the influence of including dropset exercises in different orders, both in the pre-exhaustion, as in the post-exhaustion method, and to analyze the performance of total work on the bench press and chest flying exercise. Twenty-two male volunteers with a recreational experience in ST were evaluated in six visits in non-consecutive days, at approximately the sa...

Forced precipitation of struvite (MgNH4PO4 . 6H2O) can reduce dissolved reactive phosphorus (DRP) in swine manure slurries. Optimization of this process requires that the swine manure slurry pH be increased, that magnesium be added, and that sufficient reaction time be allowed for struvite precipitation. To gather data that could be used for a full-scale continuous-flow struvite precipitation r...

Previous research has compared the effects of trunk inclination angle on muscle activation using barbells and Smith machines in men. Whether similar effects occur with the use of dumbbells or in women remains unknown. The purpose was to compare upper extremity surface electromyographical (EMG) activity between dumbbell bench, incline, and shoulder presses. Dominate arm EMG data were recorded fo...

This study aimed to clarify the relationship between upper-body strength and bat swing speed in high-school baseball players and to examine the physical characteristics of home run hitters (sluggers). The subjects were 30 male high-school baseball players with national tournament experience at the Koshien Stadium. Bat swing speed exerted by full effort was measured with a microwave-type speed-m...
