Cardiac arrhythmia-an irregular heartbeat-can develop in an instant and then quickly, sometimes fatally, spiral out of control. In the 1960s, physician L. Julian Haywood sought a way to continuously monitor heart for any rhythm changes. He his associates developed this prototype digital monitor, which they began using coronary care unit at what was Los Angeles County General Hospital, 1969. A C...
this paper proposes a method for the prediction of pore size values in hydrocarbon reservoirs using 3d seismic data. to this end, an actual carbonate oil field in the south-western part ofiranwas selected. taking real geological conditions into account, different models of reservoir were constructed for a range of viable pore size values. seismic surveying was performed next on these models. f...
in this paper two different rateless transmissionschemes are developed. in the proposed scheme, relay node candecode and forward the message to the destination if they areable to decode it, or amplify and forward the message to thedestination. based on the analysis and simulation resultsprovided in this paper, the proposed method has bettertransmission time than the scheme which only the relay ...
forward osmosis (fo) has recently drawn attention as a promising membrane based method for seawater and brackish water desalination. in this study, we focus on the use of calciun chloride (cacl2) and potassium bicarbonate (khco3) as inorganic salt draw solution candidates due to their appropriate performance in water flux and reverse salt diffusion as well as reasonable cost. the experiments we...
مقدمه: تصویر برداری مولکولی جهت بررسی تغییرات پاتولوژیک در اندازۀ سلولی و زیر سلولی استفاده می شود. این روش به طور گسترده جهت تشخیص و درمان بیماری های پوستی و عروقی به کار می رود. یکی از انواع تصویر برداری های ملکولی، روش برش نگاری فلورسنت ملکولی است که در آن مادۀ فلورسنت در محل ضایعه تزریق می شود سپس نمونه تحت تابش پرتوی لیزر قرار می گیرد و بافت هدف مبادرت به تابش پرتوی فلورسنت می نماید. شدت ر...
