W heelchairs provide mobility for millions of people with physical impairments. However, prolonged manual wheelchair use can lead to pain and repetitive strain injury (RSI) of the upper extremities. The number of manual wheelchair users experiencing pain tends to increase with the time spent using a wheelchair. Although manual wheelchairs have improved tremendously over the past 15 years, many ...

Continuous flow is one of the main focuses of scheduling repetitive projects. Construction practitioners and researchers have proposed approaches to maintain continuous flows. However, many of these approaches only consider deterministic activity durations or have some other methodological limitations. Accordingly, a continuous flow simulation model is presented in this paper in order to overco...

Femoroacetabular impingement (FAI) is a mechanical process by which the human hip fails due to pathological contact between the skeletal prominences of the acetabulum and the femur. This repetitive pathological contact occurs during normal activities of daily living as well as, more prominently, in an athletic population. This causes a microtraumatic effect and subsequently irreversible chondra...

finding repetitive subsequences in genome is a challengeable problem in bioinformatics research area. a lot of approaches have been proposed to solve the problem, which could be divided to library base and de novo methods. the library base methods use predetermined repetitive genome’s subsequences, where library-less methods attempt to discover repetitive subsequences by analytical approaches. ...

OBJECTIVE This study investigated the immediate effects of repetitive neuromuscular electrical stimulation (NMES)-assisted grasp-and-release activities on the hand of patients with tetraplegia. METHOD Three participants with C-5-C-6 tetraplegia underwent grasp training with sequential application of NMES to wrist extensors, finger flexors, and finger extensors to assist participants in graspi...

The biosorption of lead(II), cadmium(II) and nickel(II) ions from aqueous solution by Spirulina platensis was studied as a function of time, concentration, temperature, repetitive reactivity, and ionic competition. The kinetic results obeyed well the pseudo second-order model. Freundlich, Dubinin Radushkevich and Temkin isotherm models were applied in describing the equilibrium partition of the...

The systemic effects of wearing an industrial back belt for a repetitive asymmetric lifting task between knee and waist height have been investigated. Belt wearing significantly reduced the average heart rate by 5.3 beats per minute, constituting 21% reduction of the metabolic cost due to the exercise. Back belt significantly reduced the average systolic blood pressures by 9 mm of Hg. For manua...

This study dealt with the language disorder of main character in "Please Stand By" movie. The aims this were to describe symptoms and types who suffered from Asperger Syndrome. descriptive qualitative method was used supported by psycholinguistic approach using Carrol's theory describing faced found out that movie experienced two first social communication interaction second one restricted, rep...

BACKGROUND Submaximal eccentric exertions occur occupationally when rapidly rising tool-generated forces exceed the operator's capacity to react against them. The purpose of this study was to investigate the effects of short duration repetitive submaximal eccentric forearm exertions at levels comparable to industrial power hand tool use on dynamic mechanical properties (stiffness, effective mas...
