We split 100 porcine flexor tendons into five groups of 20 tendons for repair. Three groups were repaired using the Pennington modified Kessler technique, the cruciate or the Savage technique, one using one new device per tendon and the other with two new devices per tendon. Half of the tendons received supplemental circumferential Silfverskiöld type B cross-stitch. The repairs were loaded to f...

Conductometric gas sensors based on SMO films must be heated to temperatures up 550 °C in order initiate the molecular adsorption process at film's surface. Very often platinum is used as microheater material. The long-term reliability of these devices are primarily associated with mechanical stability micro-electro-mechanical systems (MEMS) structures hold suspended and thermally isolated from...

Continuous force output containing numerous intermittent force pulses is not completely smooth. By characterizing force fluctuation properties and force pulse metrics, this study investigated adaptive changes in trajectory control, both force-generating capacity and force fluctuations, as fatigue progresses. Sixteen healthy subjects (20-24 years old) completed rhythmic isometric gripping with t...

the efficiency and robustness of reliability methods are two important factors in first order reliability method (form). the conjugate choice control (ccc) and directional chaos control method (dcc) were developed to improve the robustness and efficiency of form formula using the stability transformation method. in this paper, the ccc and dcc methods are applied for reliability analysis of a co...

The statistical properties of failure are studied in a fiber bundle model with thermal noise. We show that the macroscopic failure is produced by a thermal activation of microcracks. Most importantly the effective temperature of the system is amplified by the spatial disorder (heterogeneity) of the fiber bundle. The case of a time dependent force and the validity of the Kaiser effects are also ...

background: renal complication of leptospirosis is common and its clinical manifestations vary from urinary sediment changes to acute renal failure. the aim of this study was to determine the final outcome of renal involvement in leptospirosis. methods: this longitudinal prospective study included all serologically confirmed cases of leptospirosis with evidence of renal failure. all patients we...

Abstract Experiments have long shown that zones of near vanishing deformation, so-called “dead zones”, emerge and coexist with strain localization inside deforming granular media. To date, a method can disentangle these dynamically coupled structures from each other, pre- to post- failure, is lacking. Here we develop framework learns new representation the kinematic data, based on complexity gr...

We have carried out a quantitative analysis of the force-interval relationship of the human left ventricle and compared it to previous studies done in both intact subjects as well as isolated muscle. The characteristics of the force-interval relationship of the normal patient resembed those of normal isolated mammalian muscle (except when exposed to high levels of catecholamines). The relations...

By comparing the physiological adjustments that occur when two similar fatiguing contractions are performed to failure, it is possible to identify mechanisms that limit the duration of the more difficult task. This approach has been used to study two fatiguing contractions, referred to as the force and position tasks, which differed in the type of feedback given to the subject and the amount of...

Who now reads Norman Dixon’s The Psychology of Military Incompetence, published 40 years ago, and does it matter ? Historical examples of military incompetence – sometimes referred to as ‘military blunders’ or in the case of Elliot Cohen and John Gooch, 1 as “military misfortunes” or failures – are legion : the failure of the Royal Navy to defeat the German High Seas fleet at Jutland in 1916 – ...
