Abstract As a plasma-based method, diaphragm discharge plasma, an underwater discharge, exhibits relatively high production rate and efficiency of hydrogen peroxide (H 2 O ). This study aimed to characterize the energetic state plasma H mechanism by optical emission spectroscopy, evaluating excitation temperature, gas electron density, their temporal variations. The temperature was approximatel...

the total vitamin c content in human plasma is widely accepted as an indicator of the tissue status of vitamin c. a liquid chromatography method with ultraviolet detector (264 nm) for measuring ascorbic acid in human plasma was developed. a c18 reversed-phase column and cetrimide as an ion-pairing agent was employed. ascorbic acid (aa) was measured after reducing l-dehydroascorbic acid to l-asc...

It is often necessary to analyze the time response of a tracer. A common way of analyzing the tracer time response is to use a compartment model and estimate the model parameters. The model parameters are generally physiologically meaningful and called “kinetic parameters”. In this paper, we simultaneously estimate both the kinetic parameters at each voxel and the model-based plasma input funct...

in this experimental work, by using the method of plasma-chemical etching, we have dealtwith the causes of the creation of a distorted layer on the surface of silicon wafers during mechanicalmachining processes, in addition, the elucidation of connections between the structure of this layer andcharacteristic parameters of the mechanical strength of these wafers have been studied. experimentalre...

Background: The aim of this study was to evaluate seminal plasma coenzyme Q10 levels and oxidative stress in patients with different types of male infertility. Materials and Methods: The study took place in the Department of Chemistry and Biochemistry, College of Medicine, Al-Nahrain University- Baghdad-Iraq from the period of November 2004 till July 2006. Sixty patients with male infertility w...

The aim of this study was to characterize the effect of typhoid fever on pharmacokinetic parameters of levofloxacin (LF) and compare the pharmacokinetic parameters of the said antibiotic in healthy human volunteers and patients with typhoid fever. Total of 12 subjects were divided into two groups “A” (healthy volunteers) and “B” (typhoid patients). Single oral dose of LF 500 mg was given and 5 ...

Deposition process for thin insulator used in polysilicon gate dielectric of thin film transistors are optimized. Silane and N2O plasma are used to form SiO2 layers at temperatures below 150 ºC. The deposition conditions as well as system operating parameters such as pressure, temperature, gas flow ratios, total flow rate and plasma power are also studied and their effects are discussed.  The p...

In this study, age-dependent changes of sperm quality parameters in Rutilus frisii were investigated. Also, fertilization capacity of breeders was tested using two age groups of males (3 and 4 year old breeders) and one female group (i.e. 4 year old breeders). For fertilization trials, the breeders were crossed randomly among age classes. Between the two age groups, spermatological parameters d...
