Dye Dilution Curve Obtained from the Retinal Artery of Rabbits

Detection of bronchial blood flow from earpiece dye-dilution curve.

In an attempt to detect an increased bronchial blood flow in man from the earpiece dye-dilution curve, the reliability of three indexes was investigated by comparing them with the values of bronchial blood flow measured from the left atrial dye-dilution curve following dye injection into the aortic root. The first index is obtained from the Cp method, in which the ratio of the peak concentratio...

Studies on light reflection of blood in the application of fiber optics for dye-dilution curve.

The mechanism of light reflection in blood, which is the underlying principle for the use of fiber optics in in vivo densitometry or oximetry, was investigated theoretically and experimentally using bovine blood. The results are summarized as follows. 1) Theoretically, the intensity of light reflected, I, was represented by a formula: I=lo•~e-2KC•~[(1-P)•~r•~a, where I, K, C, p, and a were inci...

the effect of traffic density on the accident externality from driving the case study of tehran

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...

A simplified method for calculation of the leftto-right shunt from a single earpiece dye-dilution curve.

In a preceding paper of ours,1 it has been reported that the estimation of shunt magnitudes can be done by using a single earpiece dye-dilution curve with some correction of the build-up time in infants and children with the left-to-right shunt. The present report describes a new, simplified method devised for the calcula tion of the shunt values using a single earpiece dye-dilution curve, beca...
