A NEW INSTRUMENT FOR OBTAINING INDICATOR DILUTION CURVES USING A RADIOACTIVE TRACER, I125

A New Instrument for Obtaining Indicator Dilution Curves Using a Radioactive Tracer, I-125.

The use of indicator dilution curves has now become established as a routine procedure in studies of the circulation. Dyes are the commonly used indicators and the time concentration curve is obtained by intermittent sampling or by a continuous technique with an indwelling needle at a suitable sampling site. More recently radio-iodinated human serum albumin (1125HSA) has been successfully used ...

A New Approach for Obtaining Settling Velocity in a Thickener Using Statistical Regression: A Case Study

In this research work, the parameters affecting the settling velocity within the thickeners were studied by introducing an equivalent shape factor. Several thickener feed samples of different densities including copper, lead and zinc, and coal were prepared. The settling tests were performed on the samples, and the corresponding settling curves were plotted. Using the linear regression analysis...

Indicator dilution curves in atrial septal defect.

The indicator dilution technique has evolved into an invaluable method for the detection and localization of congenital and acquired cardiac shunts. The groundwork for much of the work in this field has been laid by Wood, Swan, and Helmholz (1957); Swan (1959); Hetzel, Swan, and Wood (1959); Braunwald, Tanenbaum, and Morrow (1958) and Braunwald and Morrow (1960). Indocyanine green is the most c...

Arterial Indicator-dilution Curves in Aortic Incompentence.

a new approach to credibility premium for zero-inflated poisson models for panel data

هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...
