there is a substantial evidence that plyometric training significantly increases muscular strength and vertical jump. due to the vigorous nature of this type of training, however, there is a risk of incurring musculoskeletal injuries. therefore, conducting plyometric exercise programs in an aquatic environment might lead to significant improvements in vertical jump with possibly a lower risk of...

One of the major industry problems is the flow boiling, where reaching to the critical heat flux (CHF) condition can lead to a temperature jump and damage of the systems. In the present study, the effects of a uniform change in tube diameter on subcooled flow boiling and CHF was numerically investigated. The Euler-Euler model was used to investigate the relationship between the two liquid and v...

We consider a conformable fractional Sturm-Liouville problem with the discontinuous(or jump) condition inside interval. The asymptotic formulas for eigenvalues, nodal parameters (nodal points and lengths) of this are calculated by modified Pr?fer substitutions. Also, using these formulas, an explicit formula potential functions is given. After all, we discuss Lipschitz stability considered prob...

In numerical simulations boundary layers can be treated as jump conditions inheriting detailed physical effects that emerge inside the thin layer. The presented approach, first applied by Class et al. [3], is used to determine such in integral form. It an electro-hydrodynamic problem with a Debye-layer direct vicinity charged solid wall.

Hydraulic jump on adverse stilling basin is an unstable phenomenon which causes some complexities in controlling of the   jump. This paper considers the stability of free hydraulic jump on adverse stilling basins from a theoretical point of view. A minimum value of upstream Froude number is needed to produce the free hydraulic jump on adverse stilling basins which was presented by a theoretical...

The purpose of this study was to compare the kinetics, kinematics, and muscle activation patterns of the countermovement jump, the power clean, and the jump squat with the expectation of gaining a better understanding of the mechanism of transfer from the power clean to the vertical jump. Ground reaction forces, electromyography, and joint angle data were collected from 20 trained participants ...
