abstracta novel floatation-spectrophotometric extraction method was developed for the recovery of tin (ii) from aqueous samples prior to determination by uv spectrophotometric detection. the method is based on the formation of a complex between tin (ii) and kalmagyte in ph=8. the complex is floated in the interface of n-hexane and aqueous phases. after removing the aqueous phase, the floated pa...

antibiotic resistance is a public concern, worldwide. the purpose of this study was to survey the antibiotic susceptibility pattern in the microorganisms isolated from the clinical samples in shahid faghihi hospital of shiraz, iran. in this study, the microorganisms were isolated from the blood, bone marrow, pleural fluid, csf and vaginal discharge. antibiotic susceptibility test was performed ...

Antialiasing is a necessary component of any high quality renderer. An antialiased image is produced by convolving the scene with an antialiasing filter and sampling the result, or equivalently by solving the antialiasing integral at each pixel. Though methods for analytically computing this integral exist, they require the continuous two-dimensional result of visible-surface computations. Beca...

Overt exploration or sampling behaviors, such as whisking, sniffing, and saccadic eye movements, are often characterized by a rhythm. In addition, the electrophysiologically recorded theta or alpha phase predicts global detection performance. These two observations raise the intriguing possibility that covert selective attention samples from multiple stimuli rhythmically. To investigate this po...

Amethod wasdeveloped using liquid chromatography linked to atmospheric pressure ionization-tandem mass spectrometry (LC-MS-MS) for the measurement of the opiates, morphine, codeine, 6-monoacetylmorphine (6-MAM), acetylcodeine (AC), and heroin in oralfluid collected from patients attending a substance abuse clinic. Of the513oralfluid samples tested, 297 showed detectable concentrations of1 or mo...

One of the most commonly used statistical techniques is the comparison of two independent samples of measurement data. More specifically, the comparison of the means of two independent samples. This is often the basis for making a decision to go with a particular method, process or supplier. The validity of the procedure hinges on the random selection of items for each sample. The correctness o...
