The condensation or polymerization procedure was used with formaldehyde (HCHO) at temperature 70 to 80 ˚C for 2-3 h. The prepared Schiff base BHNMXD and its respective resinPMBHNMXD were recrystallized from methanol to attain pure resin. After successful synthesis of Schiff base and resin was characterized by different instrumental techniques such as; CHN, elemental microanalysis, thermogravimetric analysis (TGA) studies of Schiff based resin, energy- dispersive x-ray spectroscopy EDS mass spectrometry, E.I-MS (electron impact ionization), 1HNMR spectroscopy and MALDI-TOF mass spectrometry clearly investigated the molecular weight and structural information of synthesized compounds. The FT-IR spectra of resin PMBHNMXD showed stronger absorption band at 1632 cm-1 of azomethine >C=NH confirming the compound formation. The SEM analysis showed the morphology of Schiff base and resin showing, longitudinal spherical rough, inflexible and rigid structure. The structures and components were carefully investigated by X-ray diffraction .The crystallographic evaluation of Schiff base and its resin, aproved the monoclinic sharp crystalline structure. These active materials have shown high efficiency against the antifungal growth of Aspergillus Flavus (G-ve), Candida albicans (G-ve) and Aspergillus Niger (G-ve),by agar well diffusion method.","PeriodicalId":21635,"journal":{"name":"SINDH UNIVERSITY RESEARCH JOURNAL -SCIENCE SERIES","volume":"98 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77341716","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}

All respondents were randomly selected and interviewed. The study revealed that all the vendors were male (100 %). Among the vendors, 95% were literate (at least primary education) and 50% were ≤ 30 years. Food safety related training was not received by any vendor in study area. A significant majority of vendors did not know about good handling practices (GHP) and good manufacturing practices(GMP) i.e. 52.5 and 45%, respectively, while an overwhelming majority (80%) was familiar to food borne illnesses (FBIs). Most vending carts were in poor hygienic condition (72.5%), infested with flies (97.5%)and only 32.5 % vendors were in clean clothes. Some vendors experienced infectious diseases like, hepatitis (5%) and tuberculosis (7.5%). In case of population using street vended foods, only 5% were satisfied with hygienic condition of food vendors, quality of raw material (10%), serving utensils (7.5%) and food freshness and purity (15%), therefore, significant majority (87.5%) of population using street foods experienced FBIs. Meanwhile, main reasons for consuming street food were low food cost (90%), ease (85%) and palatability(75%).Significant associations (p < 0.05) were observed between vendors’ demographics (age and education) and their vending practices, while highly significant associations (p < 0.05) were recorded between street food users’ education and perceptions. In vendors’ self-reported analysis, average valuefor vendors’ knowledge remained 7.75, vendors’ attitude stayed 23.18,while average value for vendors’ food safety practices was recorded as 6.51. Study concludes that venders’ food safety knowledge and practices are poor, therefore, population using street foodsare not seemed satisfied with safety measures in street food vending.","PeriodicalId":21635,"journal":{"name":"SINDH UNIVERSITY RESEARCH JOURNAL -SCIENCE SERIES","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87277638","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}

This study provides information about trichomes of six species add name of species here of genus Solanum. This study will also helpful to produce more information to develop modern nomenclature for trichomes. The plant material was taken from Sindh University Herbarium as well as new plant substance was gathered from the field for the study. During the trichomal analysis the plant components were observed under stereo zoom microscope. Provisional and long-term slides were produced. For the scanning electron microscopic observation, the plant material was treated with ethanol alcohol for 20 minutes, ca 1mm2 piece of specimens were fitted on the stubs made of metal with double-sided cellophane tape and also covered with C-30-50 nm gold by Jeol JFC- 1500 Ion sputter machine. After coating samples were observed as well as pictures were captured on different magnifications by enhancing voltage between 5-15 KV by Scanning Electron Microscope (SEM) Jeol JSM-T200 & Jeol JSM-T6380 at Biological Research Centre and Central Research Laboratory Karachi, University of Karachi.","PeriodicalId":21635,"journal":{"name":"SINDH UNIVERSITY RESEARCH JOURNAL -SCIENCE SERIES","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87312131","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}
