Several recent reports have indicated that catecholamines may act directly on the crossbridge cycle, independent of intracellular calcium concentration changes. The present study investigated the effect of isoproterenol on peak force during twitches at constant sarcomere length and unloaded velocity of sarcomere shortening in isolated right ventricular trabeculae of hearts with V1 or V3 isomyos...

AIMS The aim of this study was to determine whether Subjective Interpretation of paper markings is a reliable method for identifying the relative occlusal force content of tooth contacts. METHODOLOGY 295 clinicians selected the "Most Forceful" and "Least Forceful" occlusal contacts in six occlusal-view photographs of articulating paper marks that were later compared against computerized occlu...

Little information regarding variation of basic preparation guidelines in stress distribution of teeth covered with ceramic crows has been available. The incomplete fit of full crown restorations remains a critical problem for dentists, leading many researchers to study this problem. Finite element analyses have been used for many investigations, because they can reproduce structures of various...

The paper describes the use of an objective method for the quantitative analysis of the relationship between the posterior cross-bite and the occurrence of occlusive interferences and damages to the mandible muscle elevator. Two groups of subjects were selected for the analysis: 10 patients with unilateral cross-bite and 10 students without any symptoms of temporomandibular disorders (TMD). By ...

Techniques for predicting the availability of CPU resources associated with the execution of multiple concurrent Java threads on a multi-core architecture are introduced. Prediction of CPU availability is important in the context of making thread assignment and scheduling decisions. Theoretically derived upper and lower bound formulas for estimating CPU availability are introduced. Input parame...

In this paper, a two-dimensional computational model is proposed for predicting the initiation position and propagation path of subsurface crack of spur gear tooth flank. In order to simulate the contact of teeth, an equivalent model of two contacting cylinders is used. The problem is assumed to be under linear elastic fracture mechanic conditions and finite element method is used for numerical...
