Hydro-induction sediment discharge technique (HSDT) aims to prevent reservoir sedimentation by withdrawing the discharge water from the reservoir bottom to suck up and discharge sediments, and by inducing vertical vortexes and undercurrents in the reservoir bay to keep sediments agitated and moving. The technique is facilitated with an innovative discharge conduit system having bottom intakes t...

background and objectives: discharge against medical advice (dama) is a significant healthcare problem posing negative impact on effectiveness of patient care and costs of the health system. in order to address this problem, first the potential influencing factor should be identifies. this study followed two major objectives: first, to evaluate the prevalence and potential causes of dama, and s...

the estimation of instantaneous peak discharge is important for watershed management because there is ainsufficient climatic and hydrologic data in countries such as iran. researchers have been forced to link constantparameters (geomorphology) and variable parameters (hydrology) to models with minimum dependence on climaticand hydrologic data for hydrologic estimation. the present study used a ...

side weirs are flow diversion devices that are widely used in irrigation, drainage and urban sewage systems. the present study focuses on the investigation of the effect of oblique side weirs on the discharge coefficient of a side weir under subcritical flow condition in rectangular channels. in this study 106 laboratory tests were conducted and the results were analyzed to find out the influen...

introduction: one of the most important indices of effectiveness and delivery quality of sanitary and medical services is patient satisfaction with hospital services. it is necessary that hospitals pay attention to patient's needs and ensure their satisfaction. therefore the current study was conducted with the aim of identifying the level of patient satisfaction with hospital services delivere...

introduction: discharge against medical advice (dama) can be an important indicator of patient dissatisfaction. this study examined the reasons for the dama in shafa hospital (kerman, iran). methods: this was a descriptive cross-sectional study within august 2010 to march 2011 on patients in this hospital. over 9295 inpatients were discharged, 483 had dama and were assigned 190 contacts and out...

introduction: halitosis is a common and devastating condition, which may affect up to 1/3 of the population. it can be classified either as genuine halitosis, pseudohalitosis, or halitophobia. genuine halitosis is more common and usually related to an organic pathology such as periodontitis. malodour molecules such as sulfur compounds that arise from bacterial interactions generate the basis of...

Environmentally friendly nature and the direct impact of gabion weirs on the quality parameters of rivers as well as simple design and construction of such structures, has putted them under consideration in the recent years. In this research, Hydraulic parameters of gabion crump weirs including water surface profile, discharge coefficient and through flow discharge are investigated numerically ...
