Flow separation at water intake is the main cause of head loss and flow discharge reduction. As a result, study of shape and size of separation is very essential when designing an optimum water intake. Water intake is normally built with a 90 degree angle to the main channel flow direction. However, the flow structure in this type of water intake consists of large separation size along with ...
For managing the discharge of water resource, utilizing high precision measuring instruments and workers is necessary that can be lead to high cost on the governments. The purpose of this paper is to present a new approach that can provide a good estimation of the well water discharge without human intervention and the use of measuring equipment. In this research, 38 wells with suitable conditi...
Abstract Introduction: Bacterial vaginosis (BV) is the most common cause of abnormal vaginal discharge in women during reproductive age. Diagnosis of bacterial vaginosis via clinical Amsel criteria remains widely competent. Objective: The aim of the study was to evaluate the effect of tinidazole tablets via Amsel criteria in Patients diagnosed Bacterial Vaginosis. Methods: In This rand...
Streambank seeps commonly originate from localized heterogeneity or preferential flow pathways (PFPs) in riparian floodplains. However, limited field data have been reported on ground water seep flows and solute transport to seeps from PFPs. The objective of this research was to build upon previous floodplain-scale investigations of PFPs by analyzing seep discharge and transport characteristics...
Introduction: Traumatic Brain Injury (TBI) is one of the most important matters of public health in which people affected often lose their functional abilities and have dependent life and in result these patients a caregiver for care and support. Thus families are at front line of challenges and great stresses. Objective:The aim of this study was to determine needs of caregivers of pati...
background: asphyxia is a perinatal accident with a high mortality rate, therapeutic hypothermia in both head or whole body was suggested as effective therapeutic methods. in this study, we compare these methods in neonates with asphyxia.methods and materials: 16 neonates with asphyxia in two hospitals including alzahra(head hypothermia) and taleghani hospital (total body hypothermia) went unde...
objectives: to determine the epidemiology of injuries of the motorcyclists in road traffic accidents (rtis) between 2008 and 2014 in east azarbayejan province of iran. methods: a cross-sectional study was performed in east azerbaijan province in imam reza hospital on motorcyclists subjected to injuries in rtis between 2008 and 2014. demographic characteristics (age, sex), duration of hospitaliz...
Effects of Fluctuation in Discharge and Head on Flow Parameters and Head Losses in Pipeline Networks
Abstract Discharge, head, flow velocity and Reynolds number are parameters in pipe networks. On the other hand, energy loss is one of factors that affect capacity as a means distributing water flow. Energy caused by several including roughness walls associated with material. Due to lack attention interrelationship these factors, sometimes there piping networks do not work optimally or function ...
