Opis:
Objective: To assess current literature focused on the influence of functional training with blood flow restriction (BFR) on muscular adaptation in adults below the age of 65 years. Methods: A systematic literature search was performed with the following databases: PubMed, CINAHL Complete EBSCOhost, and ScienceDirect. Two researchers filtered the articles according to the criteria and quality, supported by the Consolidated Standards of Reporting Trials (CONSORT) tool. Studies were limited to those with participants with a mean age between18 and 65 years. Articles were peer-reviewed, available in English, and utilized either multi-joint resistance exercises or functional exercise as the intervention. Results: The search yielded 16 studies on uninjured, older adult, injured and athletic subjects. Regardless of the population, the studies tended to favor BFR training for improvements of strength, but this was highly dependent on cuff pressure and training load. Conclusions: Current literature suggests that BFR with functional and or multi-joint strength training is successful in improving strength, hypertrophy, function and in pain reduction. Favorable results with functional BFR included procedures using relative and well-controlled occlusion pressure. More research is necessary to understand the effect of BFR on self-reported outcomes and hypertrophy in athletic and older adults.

Opis:
We have used an all-optical photoluminescence-imaging technique to measure excitonic transport in three types of GaAs structures in which the excitonic transitions vary from allowed direct-gap excitons to forbidden, doubly-indirect Type-II excitons. We f nd remarkable differences in the transport properties of these excitons. Our studies show that bulk free-exciton transport exhibits an anomalous laser power-dependent diffusivity, whereas quasi-2D interfacial excitons and Type-II cross-interface excitons do not. Additionally, we observe localization of cross-interface excitons at the potential disorder induced by the heterointerface roughness.

Tematy:
plane-flow silo

arch shape
critical arch dimension
Opis:
The paper records some of the results and observations from a pilot scale plane-flow silo with a variable geometry hopper and a fully width slot outlet. The original objectives were simply to study the shape of arches and their failure mechanisms under a range of conditions. However, the behaviour of arches did not conform to the conventional assumptions and neither did other silo behaviour. The paper contains a summary of the main findings of this work, but concentrates on the arches formed under mass-flow and non-mass-flow geometries for the filling condition.
