A sample of 36 male Wistar albino rats was randomly divided into 6 groups (A, B, C, D, E and F). Hyperlipidemia was induced by high fat diet (HFD) (banaspati ghee + coconut oil) mixed in normal chow diet. After six weeks, blood was taken through retro – orbital capillary plexus, centrifuged to get sera, stored at -20°C temperature for biochemical analysis of blood lipids. TAG/HDLc ratio (atherogenic index of plasma) was measured as log TAG/HDLc. Statistical package (SPSS ver. 21.0, IBM, incorporation, USA) analyzed the results by 1- ANOVA and post – Hoc Benforinni test (p≤ 0.05). Cholesterol, TAGs, LDLc, and HDLc shows significant decrease in F. carica and A. sativum treated experimental groups C – F compared to positive controls (P=0.0001). A. sativum shows more potent hypolipidemic potential and more significant reduction in TAG/HDLc ratio compared to F. carica (P=0.0001). The present study concludes Ficus carica and Allium sativum show hypolipidemic potential with significant decrease in TAG/HDLc ratio and they may be used to prevent atherosclerosis and coronary artery disease as simple home remedy.","PeriodicalId":21635,"journal":{"name":"SINDH UNIVERSITY RESEARCH JOURNAL -SCIENCE SERIES","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87148627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Parts of Speech (POS) is considered as one of the well understood problems of Natural Language Processing, in which natural language words and sentence are tagged or assigned grammatical classes, because tagging a single word by human hand is a time consuming and tedious job. To automate the tagging job is the way to automate the lexicons of the text of a language. Many of the languages are enriched with their POS tagging systems. Pakistani regional languages are less developed due to the many reasons and much of the work is needed in POS tagging system. Some of the regional languages have their POS tagging systems but still they need some more attention to refine their system. Some of the languages need to develop from the scratch. Balochi language has no any POS tagging system. This study presents the comparative analysis of POS tagging approaches for the national language (Urdu) and other regional languages of Pakistan.

An experiment was carried out for preparation of banana crop residue based compost enriched with other organic sources and its nutrient analysis. Three recipes of the banana residues for compost making, designed in randomized complete block design (RCBD) were made in piles separately prepared i.e. consisting banana leaves (BL) with sugar cane press mud (SPM), goat manure (GM) and poultry manure (PM). The compost prepared was subjected to laboratory analysis for electrical conductivity, pH, organic matter, organic carbon, total nitrogen, total phosphorus, total potassium, and C/N ratio. The results indicated that the maximum EC (6.12) was recorded for C2 and minimum EC (5.67) was recorded for C1. The results revealed that banana crop residue enriched with other organic sources hastened the composting process and significantly increased the organic matter (OM) (55.6%), organic carbon (36.35%), total nitrogen (TN) (2.77%), P (1.75%) K value (3.05%). Further, results revealed that C1= (Banana leaves with sugar cane press mud) compost blend was optimum and best, because this blend has rich nutrient contents. It was concluded that higher OM%, OC%, TN, P, K were observed for C1= Banana crop residues enriched with sugar cane press mud.","PeriodicalId":21635,"journal":{"name":"SINDH UNIVERSITY RESEARCH JOURNAL -SCIENCE SERIES","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86581184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Variation in load causes a similar change in the amount of current which produces opposite variation in output voltage. Microgrids typically use renewable energy resources to meet varying load demands of the local area. Such sources need power electronic converters for controlling proper voltage level for efficient operation. Hence it becomes essential to design control scheme for the DC-DC converters to stabilize the voltage in DC micro grids under any type of load variations. This research work proposes a DC micro grid structure in which sliding mode controller based DC-DC converters are implemented. Microgrid structure is then simulated using MATLAB SIMULINK where output voltage regulation is achieved efficiently in case of rise as well as fall in the load connected on DC micro gird.","PeriodicalId":21635,"journal":{"name":"SINDH UNIVERSITY RESEARCH JOURNAL -SCIENCE SERIES","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84820006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It also has been reported to acts as a reservoir of microbes that may infect, reinfect, mutate and may cause disease therefore this study was designed for analysis of prevalence, biochemical characteristics and antibiotic susceptibly of microbes isolated from different poultry litters used in Sindh province of Pakistan. A total of (n) =66 litter samples including rice husk (33), wooden bran (21) and sand (12) were collected from different broiler farms. The prevalence of bacteria were recorded as 36(54.54%) samples were positive with rice husk 20(60.60%), wooden bran 10(47.61%) and sand 6 (50.00%).The isolated bacteria were identified as E. coli in 9(45.0%) samples, followed by L.monocytogenin 3(15.0%), S. arizonaein 3(15.0%), S. aureusin 3(15.0) and P.aeroginosain 2(10.0%) samples collected from rice husk litter. Similarly, E. coliin 4(40.0%) samples, S.arizonaein 3(30.0%), S. aureusin 3(30.0%) and P.aeroginosa1(10.0%) were isolated from wooden bran, respectively. However, from sand litter only E. coliin5(83.33%) samples and S.arizonaein 1(16.67%) samples were isolated. The morphological characteristics show that E. coliwere observed as cocco-bacilli, short rods & straight rods, arranged either singly or in pairs, non-motile and gram negative. Similarly, L. monocytogeneswere coccoid rods, arranged singly & in short chains, motile and gram positive. P. aeruginosa were found in short to long cylinder or singly curved rods, arranged in pairs and short chains, motile and gram negative. Similarly, S. arizonaewere observed as rod to cocco bacilli shape, arranged single, pairs, tetrads, short curved chains & in few clusters, G -ve. However, the shape of S. aureus was round and grape like structure, arranged as in pairs, tetrads, short & irregular clusters, non-motile and gram positive. Biochemical analysis revealed that E. coli, L. monocytogen, S. arizonae and S. aureus were urease negative, catalase positive, produced acidic slant and acidic butt whereas P. aeroginosa was urease and catalase positive and produced alkaline slant and butt. Sugar fermentation indicated that E. coli, L. monocytogen, P. aeroginosa, S. arizonae and S. aureus was ferment glucose, mannitol and mannose but failed to ferment dulcitol except S.aureus. Antibiotic sensitivity test shows that E. coli and L. monocytogenwere highly sensitive to chloramphenicol and gentamycin, P. aeruginosa and S.aureus was highly sensitive to sulphamethazole and tetracycline while S. arizonae were sensitive to ampicillin and neomycin. antibiotic sensitivity further revealed multiple drug resistant or moderate sensitivity of E. coli with amoxicillin and sulphamethaoxazole, S. arizonae were particularly resistant to amoxicillin, chloramphenicol, sulphamethaoxazole and tetracycline.
