Micro-hydro-electric power is both an efficient and reliable form of clean source renewable energy. It can be excellent method harnessing energy from small rivers streams. The micro-hydro project designed to a run -of-river type, because it requires very little or no reservoir in order the turbine. water ill straight through turbine back into river stream use for other purposes. This has minimal environmental impact on local ecosystem. design procedure plant was implemented by Matlab...
Iron core loss is the major in electrical machines. It performs up to 25% of total machine losses. The efficiency calculation requires an accurate prediction accuracy losses depends largely on equivalent circuit parameter determination and measurements. In this paper, procedure iron considering variation effect supply voltage, temperature, rotor parameters due skin effect, magnetizing saturation. resistance performed as main component circuit. This a function voltage used calculate part...
Introduction: Dengue virus (DENV) is an arthropod-borne that belonged to the Flaviviridae viral family.Four known serotypes DEN-1 through DEN-4 do exist and circulate in diverse geographical regions of world causing epidemics.The management dengue patients, especially hemorrhagic fever (DHF)/Dengue shock syndrome (DSS) cases, has been a challenge Pakistan now days.Method: We have carried out comprehensive study current outbreaks infection on molecular level with aim find common serotype/s...
Hepatitis C virus (HCV) is one of the most important causes chronic liver diseases, which include inflammation, fibrosis, cirrhosis and hepatocellular carcinoma. Several factors have been proposed to determine clinical outcome HCV infection. The accurate mechanism by damages remains poorly understood. In hepatitis patients, relation between serum biochemical markers, RNA titers histological injury remain controversial.The aim this study was investigate degree damage in patients with...
The micro-hydro-electric power plant is a renewable energy which has many advantages over the same size of wind and solar plants .It high efficiency (up to 90% s), capacity factor 60%) slow rate change (due water flow varies gradually from time time).This paper deals with suitable selection components such as turbine type, main part in generator capacity, second component station.Also procedure developed for calculation transmission line voltage drop during load site, specify transformer its...
The uropathogens is the main cause of urinary tract infection (UTI). aim study was to isolate bacteria from urine samples UTI patients and find out susceptibility isolated bacteria. Bacteria were identified using both conventional molecular methods. Sanger sequence procedure used for 16S ribosomal RNA phylogenetic analysis performed Molecular Evolutionary Genetics Analysis (MEGA-7) software. In this study, Escherichia coli , Klebsiella pneumonia Staphylococcus reported as 58, 28 14.0%...
With the advancement of mobile technologies, pedagogical innovations have been emerging since last two decades. The potential use devices has attracted many educators and researchers to conduct inquiry based learning (IBL) activities in a classroom or fieldwork. In recent years, augmented reality (AR) technology become widespread for conducting using devices. literature related science education, there are limited systems found which AR is used IBL activities. We therefore designed system...
Background We previously developed a logistic regression algorithm that uses AFP, age, gender, ALK and ALT levels to improve the detection of hepatocellular carcinoma (HCC). In 3,158 patients from 5 independent sites, this algorithm, referred as "Doylestown" increased AUROC AFP 4% 12% had equal benefit regardless tumor size or etiology liver disease. Aims Analysis Doylestown using samples individuals taken before their diagnosis HCC. Methods Here, was tested at multiple time points (a) with...
INTRODUCTION: Liver cancer–secreted serine protease inhibitor Kazal (LC-SPIK) is a protein that specifically elevated in cases of hepatocellular carcinoma (HCC). We assessed the performance LC-SPIK detecting HCC, including its early stages, patients with cirrhosis, hepatitis B virus (HBV), and C (HCV). METHODS: enrolled 488 patients, 164 HCC (81 HCC) 324 controls blinded, prospective, case–control study. Serum levels were determined by an enzyme-linked immunosorbent assay-based assay. The...
Abstract Background There are conflicting data regarding the risk of hepatocellular carcinoma (HCC) after direct-acting antiviral agent (DAA) treatment. Risk HCC in HCV genotype-3 infected persons DAA therapy is not well known. Methods We prospectively studied initiated on a regimen between October 2014 and March 2017 at two centers Pakistan. All were free study initiation. was confirmed based characteristic CT scan findings. Patients followed for 12 months completion therapy. Results A...
The three-phase self-excited induction generator (SEIG) plays a basic rule in sources of renewable energy, such as wind turbines (WT). His main defect is poor regulation output voltage and frequency under variable rotor speed load conditions at stand-alone isolated area operation mode. In this paper, complete dynamic model the SEIG-WT system performed to analyze study performance transient steady-state conditions. This considers into account effect saturation magnetizing inductance,...
A 47-year-old female with a history of chronic alcoholism presented nausea, vomiting and mild epigastric tenderness. She reported subjective fever, abdominal fullness loose, watery stools had stable vitals on arrival. Examination was positive for tenderness hepatic enlargement. Computed tomography the abdomen showed circumferential thickening stomach wall, lower esophagus first part duodenum in addition to peritoneal ascites. admitted alcohol-related gastritis, acute alcoholic hepatitis,...
The present study investigates if common missense functional variants p.I148M and p.E167K in PNPLA3 TM6SF2 genes, respectively, associate with development of hepatic fibrosis cirrhosis a geographically novel cohort Pakistani chronic hepatitis C (CHC) patients.In total, 502 CHC patients [242 males, median age 40 years, 220 significant fibrosis, including 114 cirrhosis] were genotyped for using TaqMan genotyping assays. Associations between genotypes, biochemical clinical parameters...
