A looking-out portal (LOP) approach to enhance qualitative aspects of bandwidth utilisation in academic networks
(Inderscience Publishers, 2011-01-01) Ahmed, Waseem; Ansari, Zahid; Herrmann, Johannes; Abdullah, Matin
Campuses of educational institutions periodically need to increase network bandwidth to keep up with increased demand and this decision is based on the quantitative aspects of the network bandwidth utilisation. The qualitative utilisation of the bandwidth is seldom looked into. Improving the qualitative utilisation of the bandwidth may not even necessitate a network upgrade. Although blacklist-based access control techniques help to a certain degree, the findings of this research indicate otherwise. A multi-tier, whitelist-based, looking-out portal (LOP) approach is presented that promises to improve the qualitative utilisation of the network while positively impacting pertinent resource identification and location of sources on the internet. The authors draw on their years of experience serving as students and staff in various campuses of universities and colleges in various countries while making recommendations.

Background/Objectives: The alternative fuels are expected to satisfy the progressive demand for energy on the wake of the negative effects of fossil fuel on the atmosphere and resultant universal warming. In this study two ethanol fermenting Saccharomyces cerevisae were isolated from Palm juice and Raisins. Method/Statistical Analysis: Both isolates were grown in Yeast extract Peptone Dextrose (YEPD) medium and characterized for alcoholic fermentation using molasses medium and optimized for pH, thermo-, osmo-, ethanol tolerance and sugar concentration. Findings: Results showed for ethanol fermentation, 31°C temperature, 6.01 pH and 6.50% sugar concentration is the prime condition. Raisin-isolate emerged as highly thermophilic and stress tolerant in nature. Under optimized conditions, S. cerevisae isolated from Palmjuice produced 9.85% of ethanol in the medium. Application/Improvements: Creation of ethanol through fermentation appears to be a potential other fossil fuel and can be used as exclusive fuel in vehicles with dedicated engines or in fuel blends.

Objective: Monitoring trends in key population health indicators is important for informing health policies. The aim of this study was to examine population health trends in Canada over the past 30 years in relation to other countries. Methods: We used data on disability-adjusted life years (DALYs), years of life lost (YLL), years lived with disability, life expectancy (LE), and child mortality for Canada and other countries between 1990 and 2019 provided by the Global Burden of Disease Study. Results: Life expectancy, age-standardized YLL, and age-standardized DALYs all improved in Canada between 1990 and 2019, although the rate of improvement has leveled off since 2011. The top five causes of all-age DALYs in Canada in 2019 were neoplasms, cardiovascular diseases, musculoskeletal disorders, neurological disorders, and mental disorders. The greatest increases in all-age DALYs since 1990 were observed for substance use, diabetes and chronic kidney disease, and sense organ disorders. Age-standardized DALYs declined for most conditions, except for substance use, diabetes and chronic kidney disease, and musculoskeletal disorders, which increased by 94.6%, 14.6%, and 7.3% respectively since 1990. Canada’s world ranking for age-standardized DALYs declined from 9th place in 1990 to 24th in 2019. Conclusion: Canadians are healthier today than in 1990, but progress has slowed in Canada in recent years in comparison with other high-income countries. The growing burden of substance abuse, diabetes/chronic kidney disease, and musculoskeletal diseases will require continued action to improve population health. © The Author(s) under exclusive license to The Canadian Public Health Association 2024.
Exploring potato diversity: A comprehensive genetic and phenotypic analysis of quantitative and qualitative traits
(Czech Academy of Agricultural Sciences, 2024-01-01) Samiha, Tasnim Khandaker; Rahman, Md Ataur; Islam, Saiful; Jalal, Nusrat; Islam, Aparna; Nahiyan, Abu Shamim Mohammad; Department of Mathematics and Natural Sciences
For sustainable breeding in potato, a better understanding of genetic diversity within germplasm banks for sustainable breeding is needed. This study comprehensively characterised the molecular and phenotypic traits of 62 potato accessions, including advanced clones and indigenous potato varieties from Advanced Chemical Industries Limited (ACI Ltd.), Bangladesh, and 8 varieties from the Bangladesh Agricultural Research Institute (BARI). By using 9 SSR markers and 13 morphological traits, including both quantitative and qualitative traits, we observed correlation coefficients ranging from –0.3 to 0.7 for 8 quantitative traits, and Pearson's chi-square (χ2 value) ranging from 24.3 to 135.4 for 5 qualitative characteristics. Molecular analyses identified 46 unique alleles, with 93.5% polymorphism. The markers STM0031 and STM1016 had the highest PIC value of 0.9. Genetic parameters for SSR markers included effective number of alleles per locus (Ne) = 5.6, unbiased expected heterozygosity (uh) = 0.8, diversity (h) = 0.8 and Shannon’s information index (I) = 1.8. Jaccard’s similarity coefficients ranged from 0.2 to 0.8, representing significant diversity. Cluster analysis, using unweighted pair-group method with arithmetic average (UPGMA), grouped the accessions into five clusters based on SSR profiles. An association was foud between the marker STM0031 and two traits: the number of tubers per hill and the content of reducing sugars in the tubers. This study provides information on genetic diversity and marker efficacy. It will guide future breeding programmes towards the development of high-yielding and industrially valuable potato varieties. © The authors.
