We developed a biomechanical model to determine the joint torques and loadings during squatting with a backward/forward-inclined Smith machine. The Smith squat allows a large variety of body positioning (trunk tilt, foot placement, combinations of joint angles) and easy control of weight distribution between forefoot and heel. These distinctive aspects of the exercise can be managed concurrentl...

Poly (vinylidene fluoride) (PVDF) is a kind of semicrystalline organic polymer piezoelectric material. Adopting processes such as melting crystallization and solution casting, undergoing post-treatment annealing, stretching, polarization, PVDF films with high crystallinity response level can be realized. As material, shows excellent mechanical properties, chemical stability biocompatibility, li...

Abstract An adaptive low-illumination image enhancement algorithm based on the weighted least squares optimization is proposed to solve difficulty of detailed feature recognition in images that collected by visible light imaging equipment. First, converted from RGB channel LAB channel. Second, we use an edge-preserving smoothing operator coarsen smooth base layer and extract multi-scale details...

Obesity is a growing problem in the United States, and it affects the health care system in a big way. Modern imaging equipment has designated weight limits established in order to ensure patient safety while avoiding damage to the equipment itself, and at most hospitals, there is a lack of equipment that can accommodate the size of obese patients. Obesity is also detrimental to image quality. ...

Photodermatoses are skin conditions that are induced or exacerbated by electromagnetic radiation (including visible light, UV light, and infrared radiation) from the sun or artificial light sources. In Part 1 of this series we review current understanding of the pathophysiology of these processes and their classification. We also discuss technical aspects and the basic physics of photobiology a...

Effects of photoperiod on growth, eating patterns and clearance rate, secretion rate and half-life of growth hormone in serum were assessed in Holstein heifers. Sixty-four prepubertal heifers (avg body wt 102 kg) were blocked by weight into four groups of 16. Within block, each animal was randomly assigned to one of four photoperiod treatments: 16 h of cool-white fluorescent light:8 h dark (CW-...

the effects of different grazing intensities on the above and underground biomass of twospecies festucaovina l. and alopecurustextilisboiss. in the north sabalan rangelands (in shabil) were investigated. sampling on the light, medium and heavy grazing intensities in the flowering stage (the second half of june 2013) were performed. initially, from a 90-meter transects perpendicular to the slope...

 Environmental enrichment is one of the methods for improving fish growth performance. In the present trial, the effects of both light color and music on growth performance and survival of goldfish (Carassius auratus) (initial mean weight: 4.15±0.08 g) were investigated for 2 months. Two light color treatments (red light and white light) and three music treatments (M0: without music, M30:30 min...
