Complications of vascular access are an important cause of morbidity and mortality in hemodialysis patients. 1 It is widely accepted that an arteriovenous fistula (AVF) is the optimal form of vascular access, with better patency and lower infection rates than arteriovenous grafts and central

Academic Data Mining was one of emerging field which comprise procedure of examined students' details by different elements such as earlier semester marks, attendance, assignment, discussion, lab work were of used to improved bachelor academic performance of students, and overcome difficulties of low ranks of bachelor students. It was extracted useful knowledge from bachelor academic students data collected from department of Computing. Subsequently preprocessing data, which was applied data mining techniques to discover classification and clustering. In this study, classification method was described which was based on naïve byes algorithm and used for Academic data mining. It was supportive to students along with to lecturers for evaluation of academic performance. It was cautionary method for student's to progress their performance of study.

Solar energy is directly converted into electrical energy by using photovoltaic (PV) panels. The efficiency of PV panel varies with its orientation and tilt angle with the horizontal plane. In this paper, we investigate the optimum tilt angle of solar panels installed at Sukkur IBA University. The optimum angle for tilted surfaces varying from 0° to 90° in steps of 1° was calculated for the values of which the daily total solar radiation was maximum for a specific period. It was found that the optimum tilt angle changed between 0° and 61.1° throughout the year in Sukkur IBA University, Sindh Pakistan ( latitude = 27.7268 ° N, longitude = 68.8191 ° E). For calculating irradiance, optimal fixed (15 and 29.5 degrees) and variable tilt angles are used for every month of year 2019. The irradiance calculated at 15 degrees tilt angle is compared with the fixed angle of 29.5 and variable angles. It was found that optimal tilt angle for the region of Sukkur located in northern Pakistan is to be 29.5 degrees.

A highly efficient multifunctional polyvinylidene fluoride// carbon-molybdenum disulfide (PVDF//C-MoS 2) interlayer is developed by direct deposition on sulfur cathode through facile slide coating method for LiÀ S batteries. The as-developed PVDF//C-MoS 2 interlayer exhibits the polysulfide adsorption and trapping capabilities, which reduces the shuttling effects and also slows down the self-discharge in LiÀ S batteries. The first composite layer (C-MoS 2) on the cathode maximizes the level of lithium polysulfide adsorption owing to the strong dipolar interaction of MoÀ S on the polarized surface of polysulfide species. Moreover, the PVDF layer physically traps/ capture the remaining polysulfide species with its interconnected microstructure for the reutilization as active material in the cathode. The LiÀ S batteries based on interlayers deliver the discharge capacity of 1086 mAh g À 1 at 1 C with 3.0 mg cm À 2 sulfur loading and show capacity decay of 0.04 % per cycle after 1500 cycles. In contrast, the LiÀ S batteries without interlayer merely maintain the discharge capacities of 423 mAh g À 1 at 1 C with 3.0 mg cm À 2 sulfur loading and show severe capacity decay (0.12 %) after 505 cycles. The LiÀ S batteries also depict the remarkable cyclic performances with as-developed interlayer for high sulfur loading cathodes and efficiently slowdowns the self-discharge even after resting for a long time.
