in this study, a simple and reliable square wave voltammetric (swv) method was developed and validated for determination of diclofenac in pharmaceutical preparations and human serum. the proposed method was based on electrooxidation of diclofenac at platinum electrode in 0.1 m tbaclo4/acetonitrile solution. the well-defined two oxidation peaks were observed at 0.87 and 1.27 v, respectively. cal...

Based on findings primarily in cats, the grouping of spindle activity and fast brain oscillations by slow oscillations during slow-wave sleep (SWS) has been proposed to represent an essential feature in the processing of memories during sleep. We examined whether a comparable grouping of spindle and fast activity coinciding with slow oscillations can be found in human SWS. For negative and posi...

Recommender systems provide personalized suggestions to users and are critical to the success of many e-commerce sites, such as Netflix and Amazon. Outside of e-commerce, recommender systems can be deployed in fields such as intelligence analysis, for recommending high-quality information source to analysts for further examination. In this work, we present the square counting method for rating ...

Objective- The objective of the present study was to define electrocardiographic data following intranasal administration of diazepam, midazolam and xylazine with or without Ketamine in Chough. Design- To determine the heart effects of anesthetics in intranasal administration, an experimental in vivo study was employed. Animals- Ten healthy Choughs were examined in the current study...

Background Asthma is a chronic inflammatory disease in respiratory system and obesity is another inflammatory disease which incidence rate is increasing. Although, many studies have been conducted on severity of asthma and its relationship with obesity, but different results have been obtained. This study aimed to determine a relationship between asthma severity, Body Mass Index (BMI) and pulmo...

A novel configuration for automatic gain control of optical amplifiers is presented. It uses a F–P filter with 26.7 nm free spectral range and two long-period gratings (LPGs) to produce two lasing wavelengths in a single feedback loop. By bending the LPGs, the cavity losses at different wavelengths can be varied independently to achieve single and two oscillating lasers control conditions. The ...

In this study, we report the observation of oscillatory clusters in the photosensitive Belousov–Zhabotinsky reaction switching between excitable and unexcitable states. Numerical studies with a three-variable Oregonator model have been carried out in oneand two-dimensional media. Both non-flux and periodic boundaries have been characterized. Twoand three-phase clusters with standing, breathing,...

This work deals with the configuration interaction method when an N-electron Hamiltonian is projected on Slater determinants which are classified according to their seniority number values. We study the spin features of the wave functions and the size of the matrices required to formulate states of any spin symmetry within this treatment. Correlation energies associated with the wave functions ...

In this paper, we demonstrate a miniature magnetic-force-based, three-axis, AC magnetic sensor with piezoelectric/vibrational energy-harvesting functions. For magnetic sensing, the sensor employs a magnetic-mechanical-piezoelectric configuration (which uses magnetic force and torque, a compact, single, mechanical mechanism, and the piezoelectric effect) to convert x-axis and y-axis in-plane and...
