To estimate the individual danger of handling pesticides, the bio-monitoring of effects on agricultural workers is required. There has been no such research previously conducted among Libyan agricultural workers. This research was designed to study the biochemical parameters impacts of the pesticide contamination among Libyan agricultural workers at Aljebal Alakhtar, Libya. 45 blood samples were taken from male agriculture workers at Aljebal Alakhtar who had been exposed to pesticides in crop fields for a long time, while 25 blood samples were taken from a group of people who had not been exposed to pesticides (control). Kits were used to assess plasma ALT, AST, ALP, GST, SOD, total protein, albumin, globulin, total bilirubin, total cholesterol, triglycerides, HDL-C, LDL-C, VLDL-C, urea, and creatinine. The thiobarbituric acid reactive substances (TBARS) assay was used to evaluate lipid peroxidation in serum. Using a gas chromatography-electron capture detector, the blood samples were tested for organochlorine pesticide residues (GC-ECD). In comparison to controls, workers had significantly higher SOD, GST, ALP, AST, and ALT activities, as well as higher levels of lipid profile, total bilirubin, creatinine, and urea, as well as significantly higher TBARS concentrations. Furthermore, long-term pesticide exposure was also related to reduceing total protein, albumin, and globulin, as well as reduced HDL-C levels. Pesticide exposure seems to influence various biochemical markers in general. These biomarkers appear to be indicative of pesticide-related deleterious effects in agricultural workers, indicating that they should be used for routine monitoring of impacts.","PeriodicalId":276609,"journal":{"name":"Al-Mukhtar Journal of Sciences","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127558990","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}

The application allows users to know details of their salaries, including bonuses and deductions according to the salary schedule of each ministry or sector. The application currently contains salary schedules for ten ministries. The implementation consists of the following four steps: data collection of laws and payroll tables for each ministry to use as a local database for the salary application, design of friendly-use application screens using Flutter, integration of the mobile application with Firebase) backend platform by Google), and finally, preparing and deploying an Android and web version of the salary application. The results that were obtained from reviewers in the Google Play Store were satisfactory. There is an increasing local demand to add other ministries to the application. The citizens of the local community encourage providing such a service, which is considered the first of its kind. The application reached more than 100k downloads in less than a year, and the average rating is 4.5 out of 5 in the Google Play Store at the time of writing this paper.","PeriodicalId":276609,"journal":{"name":"Al-Mukhtar Journal of Sciences","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123790340","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 aimed to test some chemical compounds such as bactericides that were applied to control bacterial wilt disease under artificial inoculation conditions and their effects on the yield of potatoes under greenhouse conditions.In vitro, tested chemical compounds (Cefalexin, Gentamycin, and Copper sulphate) inhibit the growth of R. solanacerum compared with control treatment. Copper sulphate was the most effective where the Inhibition zone diameter was 6.0 to7.4mm compared with cefalexin and gentamycin, 3.6 to 5.8mm respectively, but cefalexin was moderately effective 4.2 to 5.8mm and gentamycin was less effective 3.6 to 5.8mm against the pathogen. Inhibition zone diameter was increased with increasing concentrations of tested chemical compounds. Greenhouse experiments showed that the chemical compounds used reduced the severity of potato bacterial wilt disease and increased potato yield compared with control treatment. When using Cefalexin, the mean of wilted shoots was 20.5 and the severity of disease 16.3, while when using Gentamycin as an Abiotic, the mean of wilted shoots was 22.8 and severity of disease 17.6 which was the most effective compared with Copper sulphate treatment were wilted shoot was 31.8 and severity of disease 29.6.

A total of 410 women were selected randomly and data were collected through face-to-face interviews using questionnaire forms. A chi-square test was used for independence. The majority of the participants (41.7%) were between the age of 18 and 25 years. The results showed that the majority of the participants (95.4%) had a good level of food safety knowledge. Also, the results showed a significant association between age and occupation of the participants and food safety knowledge scores (P<0.05). Twenty-four percent of the participants reported that they were exposed to food poisoning after eating dinner in the celebration halls. Only 15% of women always washed their hands before eating the meal in the celebration halls. A significant association was found between hand washing practice and food poisoning exposure (p <0.05). Only 22.4% of participants agreed that the food served inside the celebration hall was safe. It is very clear that the meals served at celebration halls need to be regulated by the repective authorities. In addition, the respective public authorities should be working hard to eliminate the negative perception of individuals about food safety practices in celebration halls.","PeriodicalId":276609,"journal":{"name":"Al-Mukhtar Journal of Sciences","volume":"100 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120877254","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}

Six aqueous extracts were prepared for both species by soaking fresh leaves in cold water, boiling leaves and leaving for 24 hours, and grinding dried leaves. The result suggests that the germination percentage was slightly affected by extract concentration regardless of the type of extraction since F-value and P-value at 0.05 confidence level were 2.93 and 0.043 respectively. However, root length showed a significant response to the type of extraction, extract concentration, and interaction between both factors as F-values reached 6.3, 12.4, and 2.4 respectively. LSD test showed the response of seeds germination was inverse with the increase of concentration. In addition, it showed that the extracts of dried leaves were higher in root inhibition than the extracts of fresh leaves. The interaction effect reached its highest values when comparing the dried leaves’ extract to the freshly soaked ones, even for the same concentrations. In conclusion, seeds of c. siliqua were able to easily start germination because the nutrition compounds needed were available in the endosperm, and the media supported them just by moisture for establishment. While for root length, the root tissue absorbed extra quantities of the inhibiting agents from media leading to failure or weakness in root development.","PeriodicalId":276609,"journal":{"name":"Al-Mukhtar Journal of Sciences","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133328924","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}
