The Performance of shooting pool, in addition to the quality of the area in which the flow collides with it, depends to the height of the jet drop, the angle of the water flow, the depth of the jet and the concentration of the jet. By increasing the height of the jet drop, the fall velocity increases and subsequently the jetchr('39')s energy will be more intrusive. Different collision area from...
In this work, we first produced microwave plasma ball, then changed the ball into a microwave plasma jet by flowing a working gas through a nozzle. The effect of working gas on the thermal characteristics of the plasma ball and atmospheric pressure microwave plasma jet was investigated. We used resonant absorption scheme by a metallic antenna inside a chamber in which led to the ionization of s...
objectives: falling is a common problem among the elderly. falling indoors and outdoors is highly prevalent among the iranian elderly. therefore, identification of the contributing factors at home and their modification can reduce falls and subsequent injuries inthe elderly. the goal of this study was to identify the elderly at risk of fall, using the ‘home falls and accident screening tool’ (h...
objectives: balance disorder is one of the most common problems after stroke causes falling and fear of falling in some patients. the balance based video games are newly used in people with motor problems. it is very important to use different interventions for balance issues. the aim of this study is to determine the effectiveness of videogame on balance and fear of falling in one participant....
using of nanofluids and ducts with corrugated walls are both supposed to enhance heat transfer, by increasing the heat transfer fluid conductivity and the heat transfer area respectively. use of a diverging duct with a jet at inlet section may further increase heat transfer by creating recirculation zones inside the duct. in this work two-dimensional incompressible laminar flow of a nanofluid e...
Background: Fear of falling is common amongst older adults, especially those who live in nursing homes. This study aimed to determinate factors associated with fear of falling and functional independence in older adults living in nursing homes. Methods: This was a cross-sectional study using a convenience sampling method to enroll 200 older adults living in nursing homes from 25 senior cente...
due to the importance of weed control and the limitations of mechanical methods in some places, in this research the water jet cutting for weed control was investigated. the cutting tests were performed on camel thorn weed in shahid bahonar university of kerman. the water jet pressure of 90 bars was achieved with the aid of a suitable pump. the cutting time was studied in a completely randomize...
background: in this study we investigated the differences of functional gait and balance measures between patients with chronic stroke with different level of concern about falling. methods: fifty-four patients with chronic stroke participated in this observational, cross-sectional study. the level of concern relating to falls was assessed by using the falls efficacy scale-international. thirty...
background : to the best of the authors’ knowledge, to date, no systematic study has been carried out in tabriz city to investigate the extent, frequency, causes, and major outcome(s) of falling accidents in the houses of rural and urban areas of this city. the current study was, therefore, undertaken to address some of these issues. methods: in this cross-sectional retrospective study, 43170 i...
