A simple spectrophotometric method for the determination of blood sugar by phenylhydrazine Hydrochlorlde

Quantitative determination of water in granites by infra-red analysis

Two methods using nujol and hexachloro-butadiene mulls are described to analyse the water content of powdered granite samples. The nujol mull analyses were carried out on a Unicam SP Ioo spectrometer using the silica content of the rock as an internal standard. The hexachlorobutadiene mull analyses were done by a twin-path Unicam SP 2oo spectrometer, using hexachlorobutadiene as the internal st...

Preconcentration based dispersive liquid-liquid microextraction for spectrophotometric determination of zinc in natural water and human blood after multivariate optimization based on Box-Behnken design

A new simple and rapid dispersive liquid-liquid microextraction has been applied to preconcentrate tracelevels of zinc as a prior step to its determination by spectrophotometric method. In the proposed method, 4-(2-pyridylazo) resorcinol (PAR) is used as a chelating agent, and chloroform and ethanol are selected asextraction and dispersive solvent. The optimization strategy is carried out by us...

A System for Continuous Estimating and Monitoring Cardiac Output via Arterial Waveform Analysis

Background: Cardiac output (CO) is the total volume of blood pumped by the heart per minute and is a function of heart rate and stroke volume. CO is one of the most important parameters for monitoring cardiac function, estimating global oxygen delivery and understanding the causes of high blood pressure. Hence, measuring CO has always been a matter of interest to researchers and clinicians. Sev...
