The length and structure of the transitional zone in the tunica media in the renal artery of adult male cats were investigated. In addition, the volume of the lumen and different layers in transitional and nontransitional zones in the right and left sides were also determined. Morphometrical, histological and stereological studies were performed on 16 renal arteries of 8 adult male cats. After ...

Background and objective: Benzene is one of the main pollutants in air and one of the most extensive chemical compound used in both natural and industrial processes. Benzene exposure leads to the most dangerous adverse health effects, particularly blood cancer. The aim of this study was to evaluate the gas station workers’ exposure to benzene by measuring benzene in breathing air and urinary tr...

In this paper a passive Neuro-wavelet on the basis of islanding detection procedure for gridconnected inverter-based distributed generation has been developed. Moreover, the weight parameters of neural network are optimized by Interactive Honey Bee Matting optimization (IHBMO) to increase the efficiency of the capability of suggested procedure in tendered problem. Islanding is the situation whe...

Lactate measurement is vital in clinical diagnostics especially among trauma and sepsis patients. In recent years, it has been shown that saliva samples are an excellent applicable alternative for non-invasive measurement of lactate. In this study, we describe a method for the determination of lactate concentration in saliva samples by using a simple and low-cost cotton fabric-based electrochem...

Because of high penetration of distributed resources in the distribution networks, the analysis of islanding protection in the multiple inverters situation has become of a great importance. In this paper a new method which analyzes the frequency based anti-islanding protection in the multiple inverters situation, is presented. The method has wide domain of applicability and analyzes the operati...

Under constant applied electric field, an analyte band traverses an on-line detection zone in an electrophoretic separation at a velocity inversely proportional to the detection time. Because analyte bands migrate with different velocities, the sensitivity of the detection system to different species can vary significantly. One approach for overcoming this problem is to change the applied elect...

An on-line multichannel Raman spectroscopic detection system for capillary zone electrophoresis using a charge-coupled device as the detector is described. Resonant, near-resonant and non-resonant excitation Raman spectroscopies are employed. The 400 cm-1 spectral window provides adequate information to identify resolved and unresolved compounds. The use of analyte velocity reduction to allow i...
