a 25-year-old afghan male was presented to the emergency department with femoral shaft fracture following fall from the height. the patient was subjected to femoral nerve block and general anesthesia. first try for performing nerve block led to vascular puncture. therefore, the needle was removed and re-inserted 1 cm lateral to first puncture site and dex injected slowly with aspiration check a...

To assess the effects of livestock grazing on soil compaction (density changes), the trampling action of livestock was simulated. The research field was located to the south west of Nazarabad in Savojbolagh district, south west of Tehran Province. Samples were annually collected based on a completely randomized design. From the triple regions (reference, key and critical) 36 cylindrical cores w...

The true value of a high jump is the maximum height that the athlete would have been able to clear cleanly, and its value generally is not known. If the bar is knocked down, the jump is ruled a foul and the athlete receives no credit, although a hypothetical bar set at a lower height would have been cleared successfully. If the bar stays up, the athlete is credited with the height of the bar. T...

We examined changes in P wave height in lead 2 of an ECG obtained during progressive exercise in 23 patients with COPD, and measured both P wave changes and pulmonary hemodynamics during exercise at a constant workload corresponding to approximately 50 to 60 percent of VO2 max in nine patients. The P wave response to exercise (delta P/delta VO2, %/ml/min), estimated by the relationship between ...

Consider a globally hyperbolic cosmological spacetime. Topologically, the spacetime is then a compact 3-manifold in cartesian product with an interval. Assuming that there is an expanding direction, is there any relation between the topology of the 3-manifold and the asymptotics? In fact, there is a result by Michael Anderson, where he obtains relations between the long-time evolution in Genera...

BACKGROUND The aim of this study was to survey minor home help services provided by Swedish municipalities with the main purpose to prevent fall injuries. METHODS If minor home help services were presented on the homepage of a municipality, an initial telephone contact was taken. Thereafter a questionnaire was administered, including questions about target groups, aim with the services, tasks...

We experimentally investigated the packing of wet monodisperse spheres with controlled falling height. The fraction are found to decrease smaller grain size and free fall A model describing effects interparticle force height on is developed by introducing a dimensionless length scale, representing extent particle rearrangement towards denser state due impacts grains. universal law observed for ...
