metabolic alkalosis is characterized by high hco3- as it is seen in chronic respiratory acidosis, but ph differentiates the two disorders. there is no characteristic symptom or sign. orthostatic hypotension may be encountered. weakness and hyporeflexia occur if serum k+ is markerdly low. tetany and neuromuscular irritability occur rarely. we report the results of retrospective data analysis of ...
Loudness of verbal commands affect the Voluntary motor response. It seems the more intensity of verbal command, the more muscle contraction force. The purpose of thisstudy was to investigate the hypothesized effect of verbal command loundness onmagnitude of a resulting voluntary isometric contraction of triceps brachi muscle. Thirthy five female subjectsbetween ages of 18-30 performed f...
We consider smooth maps on compact Riemannian manifolds. We prove that under some mild condition of eventual volume expansion Lebesgue almost everywhere we have uniform backward volume contraction on every pre-orbit for Lebesgue almost every point. 1. Statement of results Let M be a compact Riemannian manifold and let Leb be a volume form on M that we call Lebesgue measure. We take f : M → M an...
In this paper we propose a simple but effective method to modify a BVH based on ray distribution for improved ray tracing performance. Our method starts with an initial BVH generated by any state-of-the-art offline algorithm. Then by traversing a small set of sample rays we collect statistics at each node of the BVH. Finally, a simple but ultra-fast BVH contraction algorithm modifies the initia...
Left atrial function in patients with hypertensive heart disease was compared with that in control subjects. In patients with hypertensive heart disease, the time constant of left ventricular relaxation was significantly greater than that in controls (54 +/- 18 vs 31 +/- 16 msec; p less than 0.01). The ratio of left ventricular filling volume before atrial contraction (left atrial reservoir vol...
