background: the aim of this study was to investigate muscle damage indicators and electromyography activities of quadriceps muscles at 25° of hip flexion in untrained healthy females after an eccentric exercise induced muscle fiber damage.   methods : a total of 14 healthy females participated in this pre-experimental study. the subjects performed maximal eccentric quadriceps contractions at 25...

numerical study has been carried out for slot air jet impingement cooling of horizontal concentric circular cylinders. the slot air jet is situated at the symmetry line of a horizontal cylinder along the gravity vector and impinges to the bottom of the outer cylinder which is designated as θ=0°. the outer cylinder is partially opened at the top with width of w=30mm and is kept at constant tempe...

This study proposed that attenuated expression of inflammatory factors is an underlying mechanism driving the repeated-bout effect (rapid adaptation to eccentric exercise). We investigated changes in mRNA levels and protein localization of inflammatory genes after two bouts of muscle-lengthening exercise. Seven male subjects performed two bouts of lower body exercise (separated by 4 wk) in whic...

The purpose of this study was to compare 1 repetition maximum (1RM) strength, maximum power (MP), linear momentum (Mp), and the loads of 1RM responsible for maximum power (MP%) and for linear momentum (Mp%) generated in explosive concentric bench press (CBP) motion among athletes from different sports. A total of 56 athletes (13 sprinters, 16 basketball players, 16 handball players, 5 volleybal...

Over the years, working in various roles, I have done quite a lot of work in the area of team facilitation and conflict resolution. Sometimes this has been with groups of doctors like general practitioners (GPs) who are not getting along with each other. These days, a lot of my work is with teams of hospital doctors who are having difficulty in balancing their clinical and training obligations....

In this paper, the geometric relationship between mosaic images for concentric panorama acquired by slit cameras along circular paths is considered. A concentric epipolar constraint is derived for mosaic images. It is shown how the concentric epipolar constraint can be used to calibrate the slit camera using point correspondences in two mosaic images. The concentric epipolar constraint is furth...
