Clustering Techniques : A solution for e-business

The purpose of this thesis was to provide the best clustering solution for the Archipelago web site project which would have been part of the Central Baltic Intereg IV programme 2007-2013. The entire program is a merger between the central Baltic regions of Finland, including the Åland Islands, Sweden and Estonia. A literature review of articles and research on various clustering techniques for the different sections of the project led to the findings of this document. Clustering was needed for web servers and the underlying database implementation. Additionally, the operating system used for all servers in both sections was required to present the best clustering solution. Implementing OSI layer 7 clustering for the web server cluster, MySQL database clustering and using Linux operating system would have provided the best solution for the Archipelago website. This implementation would have provided unlimited scalability, availability and high performance for the web site. Also, it is the most cost effective solution because it would utilize the commodity hardware

Dolutegravir resistance in sub-Saharan Africa: should resource-limited settings be concerned for future treatment?

In sub-Saharan Africa (SSA) the burden of non-nucleoside reverse transcriptase inhibitor (NNRTI) HIV drug resistance (HIVDR) has been high over the years. Therefore, in 2018 the World Health Organization (WHO) recommended a regimen based on a integrase strand transfer inhibitor (INSTI), dolutegravir, as the default first-line antiretroviral therapy (ART) in countries in SSA. The scale-up of DTG-based regimens in SSA has gained significant momentum since 2018 and has continued to expand across multiple countries in recent years. However, whether or not the DTG robustness experienced in the developed world will also be achieved in SSA settings is still an important question. Evidence generated from in vitro and in vivo studies suggests that the emergence of DTG HIVDR is HIV-1 subtype dependent. These findings demonstrate that the extensive HIV-1 diversity in SSA can influence DTG effectiveness and the emergence of drug resistance. In addition, the programmatic approach to the transition to DTG adopted by many countries in the SSA region potentially exposes individuals to DTG functional monotherapy, which is associated with the emergence of DTG resistance. In this mini review, we describe the current trends of the effectiveness of DTG as reflected by viral suppression and DTG resistance. Furthermore, we explore how HIV-1 diversity and the programmatic approach in SSA could shape DTG effectiveness and DTG HIVDR in the region

Seroprevalence and risk factors of Toxoplasmosis among HIV infected women of child-bearing age attending care and treatment clinics in Dar es Salaam, Tanzania

Background: Toxoplasmosis in HIV-infected women of child-bearing age (HIV-WCB) increases the risk for congenital toxoplasmosis, leading to many complications. However, its magnitude is unknown in this population. Objectives: The study aimed to determine the prevalence and factors associated with toxoplasmosis among HIV-WCB. Methods: This was a cross-sectional study conducted from July to August 2020 among HIV- WCB attending care and treatment clinic (CTC) at Muhimbili National Hospital and Mnazi Mmoja hospital. Questionnaire and TORCH rapid test were used to obtain data and serological testing respectively. Data analysis was done using statistical package for social sciences (SPSS) version 20. Results: Overall, 29.7% of the study participants were positive for anti-T. gondii IgG, whereas none tested positive for IgM. Multivariate analysis showed that the probability of being infected with T. gondii increased by 57.1% for participants who consumed raw vegetables (p=0.005, aOR=0.43, 95%CI = 1.24-8.77). Other common risk factors such as undercooked meat consumption, source of drinking water, and cat ownership at home showed no association. Conclusion: A high number of HIV-WCB have not developed immunity to T. gondii in the study area. Introduction of routine screening during antenatal visits for pregnant women and further epidemiological studies are warranted in the country. Keywords: T. gondii; HIV women

高炉水砕スラグ系担体を用いた難分解性廃水の生物学的処理

金沢大学理工研究域機械工学系A biological treatment process using a biomass carrier of blast-furnace slag was studied to treat waste water from leather industry, which contains refractry organic compounds. Waste water from leather industry contains NH4-N of 150mg·l-1 and refractry organic compounds, which makes longer HRT of an aeration tank and easily generates NO2-N to induce COD.The two step biological treatment process, which consists of an activated sludge process using blast-furnace slag as a biomass carrier and a fixed bed reactor using saddle-type ceramics made from blast-furnace slag, was examined to treat waste water from leather industry efficiently.Nitrifying bacteria of Nitrobacter oxidizing NO2-N to NO3-N could be cultivated on the surface of the ceramics, which protected the accumlation of NO2-N in the effluent and restrained COD originated from NO2-N. And this process could promote the biological oxidation of the organic compounds simultaneously. Thus this process could improve the effluent quality and the treatment efficiency of waste water from leather industry
