salinity is a major limitation ecological factor for plant development in arid and semi-arid regions. the ionic imbalance, deficiency of nutrients and degradation of plant metabolites are caused by saline conditions, are affected by the reduction ratio of potassium (k) then sodium (na). in this research foliar applications of humic acid (ha) for improve the absorption of k under salt stress was...

respirators are commonly used to protect workers against workplace airborne contaminants, but this equipment may become a safety hazard by creating discomfort, disorientation and postural instability. although postural stability is critical to workers, especially those working near moving objects or on surfaces where a loss of balance may become life threatening, little attention has been given...

The ability to rise from a chair is a prerequisite for independent ambulation. Difficulty rising from a chair, moreover, is an indicator of balance deficits likely to result in a fall. In this paper we present preliminary work to affordably detect sit to stand strategies associated with balance impairment using web cameras. The long term goal is to create systems that can monitor functional mov...

the concept of imagery is to make an image of successful movement skill or a relaxing image in mind with no body training and external experience. the aim of the present study was to compare the effect of traditional and pettlep mental imagery methods on static and dynamic balance. the statistical population consisted of all female university of tehran students who had general physical educatio...

background the somatotype may influence the balance control ability. the quality of balance performance is an important factor to prevent injuries during sport activities. objectives the purpose of this study was to investigate the influence of somatotype on the static and dynamic balance indices as well as falling risk index. patients and methods a total of 141 university student healthy young...

abstract background: various types of foot orthoses are prescribed for people with flatfoot. it has been reported that orthoses not only improve the biomechanics of the lower limb, but also have good effects on some balance parameters in these subjects. it is hypothesized that the latter effect is dependent on the rigidity of the orthoses. the aim of this study was to evaluate and compare the e...

introduction: falling is a common problem after stroke that occurs following the physical and psychological problems. psychological factors such as reduce of self-efficacy in maintain balance could have an equal or even greater contribution than physical problems in falling. therefore, having a suitable tool with acceptable repeatability seems to be necessary for evaluation of individual confid...
