The recent competitive successes of a bilateral, transtibial amputee sprint runner who races with modern running prostheses has triggered an international controversy regarding the relative function provided by his artificial limbs. Here, we conducted three tests of functional similarity between this amputee sprinter and competitive male runners with intact limbs: the metabolic cost of running,...

Various shoes are worn by distance runners throughout a training season. This study measured the differences in ground reaction forces between running shoes, racing flats, and distance spikes in order to provide information about the potential effects of footwear on injury risk in highly competitive runners. Ten male and ten female intercollegiate distance runners ran across a force plate at 6....

Young swimmers are particularly susceptible to the onset of oral diseases. Objective To evaluate the oral health status in young competitive and non-competitive swimmers, involving an assessment of salivary cariogenic bacteria and secretory IgA (S-IgA) concentration. Material and Methods Before training sessions (T1), 54 competitive and 69 non-competitive swimmers had the following parameters a...

The paper studies competitive aerobics athletes body function, after making comprehensive evaluation on one group of competitive aerobics athletes body functions, obtained result is competitive aerobics athletes body function belongs to good level, by making comprehensive evaluation on competitive aerobics athletes body function, it well verifies fuzzy mathematics adaptability and effectiveness...

Global fits to precision cosmological data which show that there is a dark energy component comprising about 2/3 of the total cosmological energy also hint that a dark energy with w = P/ρ < −1 is viable, even favored. Here we discuss implications of such a surprising w, including whether it jeopardizes vacuum stability. It appears to be secure in microscopic processes, but why bulk dark energy ...

recently many researches have studied technological innovation capabilities (tics) and their impacts on firm’s competitive performance in the field of manufacturing industries. this paper pursued yam et al. (2004) framework to study the relevance of tics and firm&apos;s competitive performance in a mainly-service-based industry in iran (ict). empirical data were collected through a questionnaire...

After a short review of the arguments for the existence of Particle Dark Matter in the Universe, I list the most plausible candidates provided by particle physics, i.e. neutrinos, axions, and WIMPs. In each case I briefly describe how to estimate the relic density, and discuss attempts at detecting these particles. At the end I discuss my personal favorite, the lightest supersymmetric particle,...

In July 2014, Sweden’s full crisis response system engaged in a major operation as a small forest fire spun out of control, turning into the largest forest fire in Sweden in modern times. A number of investigations have been undertaken to understand the course of the fire and identify lessons for future crisis management. This paper presents one approach to identifying such lessons, the lessons...
