In Africa, they are a main protein source to people living close to streams and rivers; and in Nigeria, fisheries within inland waters contribute about 86% of the domestic fish production. Streams are a major source of fish production to hinterland communities and this depends on the interplay of factors like hydrological regimes, environmental degradation, riparian vegetation/ natural food, fishing pressure; and sediments and pollution. The longitudinal connectivity of the hydrological regime with flooding of lateral plains without undue hindrances from barriers like dams and diversions are important to maintaining and restoring fish population. In addition, riparian vegetation/ natural food, fishing pressure, sediments and pollution have affected fish production in streams. It therefore calls for local communities along streams to deliberate on how to manage their local resources and environment. Government should also execute projects that would provide planned flow regime to mitigate and potentially enhance fish production in fresh water streams.","PeriodicalId":122395,"journal":{"name":"International Journal of Science and Technology Research Archive","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128052452","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 was conducted to determine the prevalence of diabetes mellitus among medical students at Mutah school of medicine in Al-Karak in Jordan. A total of 350 medical students were enrolled in this observational study. The prevalence of diabetes mellitus proved to be 2.3 % (7 students) of participants (14.3% females and 85.7% males, p=0.002). About 85.7% of diabetic student (57.1% type1 and 42.4% type2) and 45.5% of the non-diabetic students show a family history of DM. The present study shows that 34.5% of the students have an over body mass index, 2.0% of them were diabetics. (P = 0, 04). hence there is no significant relationship between BMI and DM. It was found that 28.6% of diabetic students having HbA1c (7-10 gm %) with a p value =0,001. Moreover, it was found that 50% of diabetic students have skin rash, hypertension and eye complications.

Because of this, it is crucial to conduct early screening using technologies that are accessible to the population. Artificial intelligence (AI), particularly deep learning (DL), plays an essential role in this issue. DL may be an efficient approach for glaucoma screenings with the proper training. Objective: Describe the development of AI and DL over time and their use and significance in glaucoma screening. Methods: A literature search was conducted in PUBMED/MEDLINE, EMBASE, and manuscript references in English and Spanish between January 2014 to July 2022 on the role and evolution of AI and DL over the years and the usefulness of deep learning for glaucoma diagnosis. Of the 1914 abstracts reviewed, 105 articles were selected that contained information on the history of AI in medicine and the applicability of this tool for the early diagnosis of glaucoma. Findings and conclusions: We can demonstrate that deep learning can outperform glaucoma specialists in diagnosing the condition through fundus imaging data; DL is an exciting tool in the screening and early diagnosis of glaucoma.","PeriodicalId":122395,"journal":{"name":"International Journal of Science and Technology Research Archive","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131887366","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 investigation was aimed at producing biodiesel from microalgae species isolated from water samples in Keffi, Nasarawa state. Standard microbiological methods were used for isolation and identification of the microalgal isolates. The percentage occurrence of the isolates showed that Chlorella vulgaris had a 100% occurrence with Chlorella lewinii and Stigeoclonium tenue having a 50% occurrence each while Cladophora glomerata having a 25% occurrence. The growth curve showed that the micro algal isolates experienced exponential growth under daily sunlight exposure. The effect of temperature on the biomass and lipid extracted showed that Chlorella vulgaris, Chlorella lewinii and Stigeoclonium tenue had the highest biomass yields of 8.01g/l, 12.17 g/l and 15.10 g/l respectively and lipid production of 3.30 µg/l, 3.11 µg/l and 5.11 µg/l respectively at 32 ℃. Further increase in temperature led to decrease in their biomass yields and lipid production. The effects of pH showed that all the microalgal isolates had its highest biomass yields and lipid production in an alkaline pH of 7.5 but when the pH was reduced up to 4.5, the resultant microalgal biomass yields and lipid production of the microalgal isolates decreased. The fatty acid profiles of the biodiesel derived from the microalgal isolates showed that it was composed mainly of palmitic, oleic, Myristic and Stearic acids which made it a viable fuel source.","PeriodicalId":122395,"journal":{"name":"International Journal of Science and Technology Research Archive","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131326717","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 aim of this work was to study the impact of C. albicans on the resistance of S. typhi to antibiotics and to determine the influence of fungal biofilms on its growth. Reactivated clinical isolates of S. typhi (n = 5) and C. albicans (n = 5) were co-cultured on specific media containing or free of MgCl2. The colonies obtained were analysed by microscopy and an antibiogram was performed from it. The analysis indicated that in case of simultaneous growth of S. typhi and C. albicans, there is improvement in fungal biofilm formation. But when S. typhi infection is posterior to that of C. albicans, fungal biofilms stimulated in vitro are disorganized. Moreover, the sensibility of S. typhi to antibiotherapy in-vitro appeared to decrease in the presence of C. albicans , by approximately 100% with ofloxacin, amoxicillin, doxycycline, ciprofloxacin and ceftriaxone, 87.55% with cefoxitime and 80% with colistin. Altogether, the results of the present study suggest that the co-culture of both pathogens improves the infectious capacity and resistance of S. typhi to antibiotherapy through fungal biofilm.","PeriodicalId":122395,"journal":{"name":"International Journal of Science and Technology Research Archive","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132405368","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}

Different sizes of pots are needed for various tree species. An experiment was set up to investigate the best pot size for Cupressus lusitanica and Grevillea robusta species. The experiment was laid down as a RCBD with 8 treatments replicated 3 times. Treatments comprised of 4 different pot sizes as follows: large, medium, small and smallest as well as two species. Forest soil mixture was used for potting and 10 pots were used per each treatment per replicate while 7 plants were randomly selected for sampling. The experiment was carried out from September 2017 for a period of 8 months. The variables measured included; shoot, foliage and roots. ANOVA was done using Genstat package while the means were separated at P< 0.001 using LSD. The results showed that large pots had significantly (P<0.001) higher values in height, shoot fresh biomass, total fresh plant biomass and seedling stem volume compared with the other pot sizes. Large pots also showed significantly higher root collar diameter (6.23 mm) compared with the medium pot (4.33 mm). For species, Cypress showed significantly superior height (27.84 cm) and number of leaves (24.52) compared with Grevillea (18.73 and 18.27 cm respectively). In conclusion, shoot fresh biomass and total fresh plant biomass were positively correlated with pot size. This study recommends the use of large pots for raising Grevillea and Cypress seedlings in the nursery since they take 8 months to attain planting size.","PeriodicalId":122395,"journal":{"name":"International Journal of Science and Technology Research Archive","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134315308","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}
