In case of optimization of biochemical networks the best combination of adjustable parameters has to be found keeping low the costs of modification of biochemical network and reducing the risk of unpredicted side effects of processes outside the scope of the model. Dynamic models of biochemical networks usually are in form of system of differential equations and therefore can not be optimized a...
This study presents an evaluation of an adjustable keyboard based on subjective preference and wrist joint motion during typing. Thirty-five computer users used the adjustable split design keyboard for 7-14 days during their usual work and were instructed to adjust the keyboard to the opening angle they preferred. At the end of this period, three-dimensional motion analysis was performed to com...
PURPOSE To identify the specific characteristics making glasses designs, particularly those compatible with adjustable glasses, more or less appealing to Chinese children and their parents. PATIENTS AND METHODS Primary and secondary school children from urban and rural China with < = -1.00 diopters of bilateral myopia and their parents ranked four conventional-style frames identified by local...
PURPOSE To evaluate the success rate of adjustable suture techniques in horizontal eye muscle surgery in children aged 10 years and younger. METHODS A retrospective review of children who had horizontal eye muscle surgery at or before the age of 10 years. Patients were divided into 1 of 2 groups according to whether a nonadjustable or an adjustable technique was used. The preoperative measure...
BACKGROUND Driving has been associated with signs and symptoms caused by vibrations. Sitting causes the pelvis to rotate backwards and the lumbar lordosis to reduce. Lumbar support and armrests reduce disc pressure and electromyographically recorded values. However, the ideal driver's seat and an optimal seated spinal model have not been described. OBJECTIVE To determine an optimal automobile...
PURPOSE To analyze perioperative complications and postoperative explantation rates for selected readjustable male sling systems and the perineal single-cuff artificial urinary sphincter (AUS) in a large, contemporary, multi-institutional patient cohort. METHODS Two hundred eighty-two male patients who underwent implantation between 2010 and 2012 in 13 participating institutions were included...
Nanofibers fabrication nowadays has become unimaginable without mentioning or research involving the technique of electrospinning. Due to vast possibilities that this offers in regard nanofibers morphology, nanofibrous architecture, and application perspective, it main interest many scientists with various expertise profiles. Electrospun are advantageous over conventional fibers due their light...
The United States MEPS (musculoskeletal--eyestrain--psychosocial--stress) study consisted of 1 group of 28 female data entry operators. The intervention was in 3 parts: workstation redesign (including advanced ergonomic chairs, motorized adjustable workstations, advanced adjustable keyboards, adjustable copyholders, adjustable footrests, monitor support surfaces) and ergonomic training/coaching...
PURPOSE To assess the efficacy of an adjustable inspiratory occlusion valve in experimental bronchopleural fistula during mechanical ventilation. METHODS We studied six mechanically ventilated pigs in a surgically created, reproducible model of bronchopleural fistula managed with mechanical ventilation and water-sealed thoracic drainage. An adjustable inspiratory occlusion valve was placed be...
