BACKGROUND The aims of this paper are to derive a 10-year coronary risk predictive equation for adult Italian men, and to assess its accuracy in comparison with the Framingham Heart Study (FHS) and PROCAM study equations. METHODS The CUORE study is a prospective fixed-cohort study. Eleven cohorts, from the north and the centre-south of Italy, had been investigated at baseline between 1982 and...
پدیده رسوب واکس در مخازن نفتی در مراحل مختلف عملیات تولید، انتقال و فرآوری مشاهده می شود. تشکیل واکس پدیده ای نامطلوب است زیرا منجر به انسداد خط لوله و تجهیزات عملیاتی می شود که در نتیجه سبب کاهش نرخ جریان و یا افت فشار زیاد می شود و به دلیل زمان وقفه تولید برای حذف آن بسیار پر هزینه است. راه حل های متفاوتی برای کاهش رسوب واکس پیشنهاد شده است که می توان به عایق کردن، تکنولوژی های تزریق مواد شیم...
Abstract Background and objective: Universities act in an environment that is highly dynamic and flexible and Organizational Silence can affect the trust of students to administrators, On the other hand, the effect of students' educational satisfaction will change the dynamism of university. The purpose of this study is to investigate the role of organizational silence in explaining the relatio...
A three-parameter cubic equation of state has been proposed for predicting PVT of pure refrigerantssuch as R236ea, R236fa, R245fa, R245ca, R218, R227ea, and R717, from freezing point up to critical pointtemperature and pressures up 650 atm. We explore the theory of the equation of state from the view pointof Ihm–Song–Mason (ISM) equation of state, which has been derived on the basis of statisti...
In this study, predictive capabilities of apparent viscosity of oil-based drilling fluids which is used in National Iranian South Oilfields Company (NISOC) were evaluated using Newtonian and non-Newtonian models to drive a new suitable equation. The non-Newtonian models include Bingham plastic, Power law, Herschel-Bulkley, Casson, and Robertson-Stiff. To validate the results, the calculated vis...
objective: to evaluate the capability of ascitic fluid dipstick results for ph, glucose, and protein in order to predict a low serum-ascites albumin gradient (saag) at the bedside of the patient in the emergency department (ed). methods: this prospective cross-sectional study was conducted during one year in the ed of afzalipour hospital in kerman, iran. all patients with diagnostic or therapeu...
