The purpose of this study was to describe biomechanical parameters of head, upper and lower body extremities during a straight right punch throw related to performance and injury mechanism. Subjects were eight elite right-handed male (age 20.4 ± 2.1yrs height 177.4 ± 8.5 cm mass 70.4 ± 16.8 kg) amateur boxers. 3D motion analysis was used to assess the kinematics of the right side extremities ...

Cyclin-dependent kinases (CDKs) drive the cell cycle, central to which is the accurate control of chromosome replication. In Saccharomyces cerevisiae, six closely related B-type cyclins (Clb1-6) drive the events of S phase and mitosis. Either Clb5 or Clb6 can activate early-firing replication origins, whereas only Clb5 can activate late origins. Clb1-4 are expressed later in the cell cycle. Whe...

Vehicles such as buses, delivery trucks, mining equipment, and motorsport vehicles often repeat a highly defined pattern, route, or track during normal use. For these vehicles, standard dynamometer drive cycles are of little use. In this paper it is proposed that deriving a vehicle drive cycle from empirical data collected from on-board vehicle sensors would produce more accurate vehicle charac...

Plug-in hybrid electric vehicle (PHEV) technology may reduce fuel consumption and tailpipe emissions in many mediumand heavyduty vehicle vocations, including school buses. The true magnitude of these reductions is best assessed by comparative testing over relevant drive cycles. The National Renewable Energy Laboratory (NREL) collected and analyzed real-world school bus drive cycle data, and sel...

In Caulobacter crescentus, phosphorylation of key regulators is coordinated with the second messenger cyclic di-GMP to drive cell-cycle progression and differentiation. The diguanylate cyclase PleD directs pole morphogenesis, while the c-di-GMP effector PopA initiates degradation of the replication inhibitor CtrA by the AAA+ protease ClpXP to license S phase entry. Here, we establish a direct l...

This study determined the effect of the duration of the intertrain pause on the ventricular effective refractory period (VERP) measured by the extrastimulus technique using conventional eight-beat basic drive trains. In 50 subjects, the VERP was measured using a basic drive train cycle length of 500 msec, 2-msec steps in the extrastimulus coupling interval, and intertrain pauses of 0, 1, 4, 8, ...

Electric vehicle plays a significant role, in the future transportation across world. EV has potential to reduce air pollution and emission of Greenhouse gasses significantly compared existing fossil-fuel-based vehicles. Even though substantial progress can be expected area embarked energy storage technologies, charging infrastructure, customer acceptance Vehicles is still limited due problems ...

In the present study, a model of a large Lithium Polymer (Li-Po) battery for use in the simulation of Hybrid Electric Vehicles (HEVs) is developed. To attain this goal, an Equivalent Circuit (EC) consisting of a series resistor and two RC parallel networks is considered. The accuracy and the response time of the model for use in an HEV simulator are studied. The battery parameters identifica...
