Modern society strives for the development of sustainable processes that are aimed at meeting human needs while preserving environment. Membrane technologies satisfy all principles sustainability due to their advantages, such as cost-effectiveness, environmental friendliness, absence additional reagents and ease use compared traditional separation methods. In present work, novel green membranes...

staphylococcus aureus carrying pvl gene remain major health problem associated with highly virulent infections. characterization of such gene is important to know the impact and the functional significance of nucleotide variations. pcr and standard sequencing were performed for twelve sudanese strains from different sources. protein structures prediction, modeling and physiochemical analysis we...

We present a 34-year-old patient with recurrent episodes of drug refractory paroxysmal atrial fibrillation referred for pulmonary vein (PV) isolation at our institution. During isolation of the right superior PV, a dissociated escape rhythm was observed on a portion of the PV that was disconnected, while the rest of the PV showed clear left atrium to PV conduction. This report demonstrates the ...

Power-Voltage (P-V) curve and Current-Voltage (I-V) curve determine the performance of the PV system. In this work, the arrangements of the PV module were reconstructed by adding the number of PV module in 3 strings configuration from 5 to 45. This method enhance the performance of the PV system as it able to show the characteristic of the P-V and I-V curve during partial shading and maximum ir...

In relation to some inorganic membranes, polymeric membranes have relatively low separation performance. However, the processing flexibility and low cost of polymers still make them highly attractive for many industrial separation applications. Polymer–inorganic hybrid membranes constitute an emerging research field and have been recently developed to improve the separation properties of polyme...

Two sets of microemulsions, cyclohexane- and water-rich ones, were prepared with the following n-alkanols as cosurfactants: n-propanol, n-butanol, n-pentanol, and n-hexanol. The results showed the influence of the alkyl chain length of the n-alkanol on the permselectivity properties of the pervaporation technique in the breakdown of the microemulsions. The variations of the total flux rate J an...

The globus pallidus (GP) consists of two neuron populations, distinguished according to their immunoreactivity for parvalbumin (PV). The PV-immunoreactive (PV+) neurons project preferentially to "downstream" targets such as the subthalamic and entopeduncular nuclei, whereas neurons lacking PV (PV- neurons) project preferentially to the striatum, suggesting a role for PV- cells in feedback to st...

During segmental isolation of the pulmonary veins (PVs) in a patient with paroxysmal atrial fibrillation, there was a PV bradycardia that was dissociated from the left atrium in a segment of the right superior PV, whereas the remaining segments showed passive activation of a PV fascicle during sinus rhythm. Rapid atrial pacing induced a PV tachycardia in the nonisolated fascicles, and the disso...
