Due to an increasing need of energy, lack of energy resources worldwide, it is very important to optimize energy generation plant to improve efficiency and production rate .One of the most important plant, for production of water and power are dual purpose power plants. In this kind of power plant a desalination system combines with power generation cycle. According to these issues, in this pap...
introduction: world health organization (who) introduced hypertension as an epidemic in developing countries. however, hypertension is adequately controlled in only 12.5% of patients. the aim of this study was to evaluate the relationship between ramadan fasting and mean arterial pressure (map). methods: this clinical, observational study was carried out at medical o.p.d of jinnah medical coll...
background: hypertension is a risk factor for many diseases. nutritional methods are considered as major tools in lifestyle modification for lowering blood pressure. the present study was conducted to determine the level of dietary adherence in hypertensive patients. methods: this descriptive-analytical study was performed in 2015, on hypertensive patients who were referred to heart clinic of s...
in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...
leakage in water distribution networks causes waste of water and economical losses. in this paper a new method is presented to calculate nodal and pipes leakage in water distribution systems using capabilities of epanet2.10 software. the method estimate the total water losses in the system based on iwa methodology using minimum night flow (mnf) measurements. recognising the pressure dependency ...
the narrow operating window between pore pressure and fracture pressure makes drilling difficult in some operations. a feasibility study of managed pressure drilling (mpd) is carried out on iran darquain oil field. the previous wells drilled in this field showed that mud returns were lost during drilling gadvan formation. the present work addresses this problem by means of surface back pressure...
OBJECTIVE To investigate the relation between mortality and treated systolic and diastolic blood pressures. DESIGN Randomised double blind placebo controlled trial. Mortality in the two treatment groups was examined in thirds of treated systolic and diastolic blood pressures. PATIENTS 339 And 352 patients allocated to placebo and active treatment, respectively. The groups were similar at ra...
Background: The risk of cardiovascular diseases increase in diabetic patients. So, it is important for patients to achieve the optimal lipid levels. Nutrition including consumption of anthocyanins plays a primary role in reducing the risk of heart disease and hypertension. In this study, we assessed the effect of concentrated sour cherry juice (SCJ) consumption as a rich source of anthocyanins ...
Introduction: Driving crash is one of major concerns in all countries. Mental workload reflects the level of attention resources required to meet both objec­tive and subjective performance criteria, which may be affected by task demand, external support, and past experience. Mental workload has been commonly cited as a major cause of workplace and transportation accidents. The objectiv...
Background and aims: The application of computer codes and numerical modeling in studies and industry is growing. When using computer codes, the accuracy of these encodings and modelings are big questions. Comparing the results of the software with experimental results is the best method of evaluating these programs. The objective of this study was to experimentally validate a software program ...
