A stacked type stair-case patch antenna with dielectric substrate (εr= 2.33) has been conceived and is theoretically demonstrated. Unlike conventional microstrip antenna it shows remarkable improvement in bandwidth (around 20%) as well as gain (around 10.5 dBi). The proposed structure is designed with two identical stair-case patches. Thorough investigations of the proposed antenna along with t...

Stair-climbing is an important skill for promoting independence and activities of daily life and is a key component of rehabilitation therapies for physically disabled children. This thesis describes the design and evaluation of an interactive musical stairs system for children engaged in stairclimbing physical therapies. The achievement of a targeted therapeutic goal, namely, use of reciprocal...

Explosive-type strength training may alter kinetics and neuromuscular activity during stair ascent in elderly women. This may improve functional ability. Nineteen women (69.7 ± 3.4 yr) were randomly allocated to strength training (TG; twice per wk, 12 wk) or a control group (CG). Stair ascent was assessed at self-chosen (AFV), standardized (ASV), and maximal velocity (AMV) pre- and posttraining...

ISSUE ADDRESSED This study investigated the effectiveness of positive and negative-themed message prompts encouraging stair use at the point of choice between an elevator and stairwell in a professional workplace. METHODS A simple time series design using two control periods assessed the efficacy of positive and negative messages on the pedestrian choice between stairs and an elevator in a re...

fused deposition modeling (fdm) is a filament based rapid prototyping system provides us to manufacture real parts with multiple production-grade materials, such as abs-m30, pc, ppsf and pc-abs blend. fused deposition modeling technology, essentially perform using layer manufacturing process. more complex 3d physical models can be efficiently fabricated without geometric limitation by this tech...

background: patellofemoral pain (pfp) is a common affliction and complex clinical entity. deficit in neuromotor control of the core may be a remote contributing factor to the development of pfps. comparative evaluation of core and extensor mechanism muscle activation patterns between healthy group and patients involved by patellofemoral pain syndrome(pfps) in a stair stepping task is the aim of...

BACKGROUND Performance tests are important to characterize patient disabilities and functional changes. The Osteoarthritis Research Society International and others recommend the 30-second Chair Stand Test and Stair Climb Test, among others, as core tests that capture two distinct types of disability during activities of daily living. However, these two tests are limited by current protocols of...

background: the goal was to upgrade and/or uprate the traditional non-contact array by producing few modifications in the configuration of this model in order to maximize light receiving of water from the uv lamp and a better disinfection.  methods: an innovative non-contact model was made with a design based on irradiation of water, which was flowing as two thin waterfalls around a uv lamp in ...

Total knee arthroplasty (TKA) is a generally successful surgical procedure to treat end-stage knee osteoarthritis; however, suboptimal outcomes, including difficulty stair climbing, do occur [1]. Clinicians use the stair climbing test (SCT) to track functional status, where a patient ascends and descends a flight of stairs as fast as possible and a faster time suggests better function and incre...
