purpose the aim of this study was to investigate the relation between anthropometric variables and total race time including split times in 184 recreational male ironman triathletes. methods body mass, body height, body mass index, lengths and circumferences of imbs, thicknesses of skin-folds, sum of skin-fold thicknesses, and percent body fat were related to total race time including split tim...

abstract Parallel programs are frequently non-deterministic, meaning they can give diierent results when provided the same input. These diierent results arise because variations in the timing of the multiple threads cause the threads to access shared resources in diierent orders. The phenomena that cause the non-deterministic behavior have been (and continue to be) variously referred to as acce...

This study aimed to investigate the relationship between race horse breed and the frequency of limb injuries through the time of training and racing. The study population consisted of 4042 Thoroughbred and 2553 Arabian horses raced at Warsaw race Track, from 2000 to 2008. Among these horses, 94 Thoroughbreds and 32 Arabians had different limb injuries. Based on the achieved results, it is possi...

purpose many factors influence athletes’ performance including anthropometric, physiological and environmental parameters. high altitude is characterized by adverse environmental conditions that are not found at sea level. we investigated the influence of some anthropometric and physiological factors on performance in the context of the mount cameroon race of hope. methods age, height, weight, ...

The idea of replacing a divergence constraint by a divergence boundary condition is investigated. The connections between the formulations are considered in detail. It is shown that the most common methods of using divergence boundary conditions do not always work properly. Necessary and sufficient conditions for the equivalence of the formulations are given. ∗This work was supported by the Uni...

introduction: rotary nickel-titanium (niti) instruments are thought to allow shaping of narrow, curved root canals more efficiently and more effectively than stainless steel hand instruments. however, the continued search for even more effective and safer instruments has resulted in new rotary systems being introduced on a regular basis. the aim of this study was to compare shaping parameters o...

introduction: the aim of this study was to compare centering ability and dentin removal of three rotary systems in curved root canals of extracted teeth. materials and methods: sixty root canals of mandibular first molars with curvatures ranging between 25-35 o were divided into three groups of 20 teeth each. based on pre-instrumentation radiographs that assessed the angle and the radius of can...
