Abstract: Due to the increasingly competitive and globalized markets, companies seek to explore new sources of competitiveness by optimizing their supply chains and their relationships with their stakeholders. Studies show that the potential gains expected by a company that is solely interested in its internal management are very limited when compared to the potential gains throughout the supply chain. The Third Party Logistic (3PL) is chosen in this case to take charge of part or all of the logistics of the company. The terminology third party is due to the fact that is not the logistics provider who owns the products but participates in the supply chain at the points between the manufacturer and the user of a given product does. Currently, in a group decision-making context, choosing the most suitable 3PL supplier is a major challenge. In practice, some decision makers (DMs) intervene in the selection of 3PL suppliers, and each has their own perspective and wants to consider criteria that are not generally the same for all DMs. In this case study, we have coupled the Fuzzy SWARA (Step-wise Weight Assessment Ratio Analysis) method with ARAS-H (Hierarchical Additive Ratio Assessment). The main goal is to improve the decision-making process, build more efficient models and meet the needs of DMs. The proposed model is used to solve the 3PL problem of a company selling steel products.

Abstract: This article demonstrates the binomial of risks that threaten the execution phase according to the Brazilian legal system in relation to the interests of the creditor, when an incessant search is created to reach the debtor’s assets, sometimes achieving high percentages of the debtor’s earnings. The study demonstrates the consequences on the impact of business activity, putting at risk the company’s obligations with payments of legal relevance, such as employees and taxes. As part of this study, a brief explanation is made of the principles that guide the execution and assist in its correct application focused on the balance of the creditor-debtor, being presented by the author a summary of the concept and functioning of the implementation process of the executive phase in the Brazilian procedural system, explaining about the weakening of the principles of the social function of enterprises and lower onerity of the debtor until reaching definitions on each term of constriction. Finally, it is demonstrated in practice the attachment of the companies' revenue and its consequences, through real cases where see succeeded in reducing the percentage initially applied, in order to achieve the result to the creditor without seriously injuring the financial health of the debtor undertaking, threatening its bankruptcy.

Abstract: The Southern and Eastern parts of Africa are the most hit by HIV/AIDS in the world and a huge financial commitment is required to control the spread of the disease. Of these countries, Kenya and South Africa have been able to increase prevention and treatment services due to their financial commitment to fighting the epidemic. However, studies have shown that most of the financial commitment comes from private donors and the private sectors are recently becoming reluctant to release funds. It is therefore important to ensure that the available funding is effectively utilised. Studies in 2018 show that infections occurred mostly among the key populations on the Kenyan Northern Corridor highway; such as sex workers and truckers. Moreso, transactional sex which involves cash transfer is the main mode of transmission of HIV/AIDS along the Northern corridor highway in Kenya. In this paper, we study the effect of funding on HIV transmission between truckers and female sex workers. A mathematical model with funding parameters is developed and analysed to determine the effects of funding on the HIV transmission dynamics between truckers and female sex workers. The reproduction number is obtained using the next-generation matrix and the conditions for the stability of the equilibrium points are established. The model is fed into the MATLAB ode45 solver and a numerical simulation is carried out. The results show that increasing circumcision funding reduces the rate of migration from the Susceptible class to the Infected class. Also, increasing treatment funding increases the Treatment class and reduces the overall number of AIDS-related.

Abstract: Natural fiber reinforced composite materials have been gaining popularity because, natural fibers are cheap and biodegradable. Pineapple leaf fiber (PALF) is a natural fiber and an agro waste. This PALF was treated with sodium hydroxide to clean the surface. 10%, 15%, 20%, 25% and 30% PALF based epoxy composites were fabricated by hand-lay-up technique. The mechanical properties such as tensile strength (TS), percentage of elongation at break (%Eb) and impact strength (IM) for composites were found to increase with increasing fiber content. The highest TS, %Eb and IM for 30% PALF based epoxy composite were 51.6 MPa, 15.882% and 14.189 Kg-cm respectively but tensile modulus (TM) was decreased with increasing fiber content. Degradation both in water and soil were done and the mechanical properties during degradation decreased a little bit over time because of the hydrophobic epoxy (matrix) material. 2.5 KGy, 5.0 KGy, 7.5KGy and 10 KGy gamma radiation doses were applied to composites and the effect of these doses were analyzed. For PALF based epoxy composite TS, TM, %Eb and IS values increased for certain value of gamma doses and for 7.5 KGy, these values were the highest while the values decreased in the increasing gamma radiation. Thermogravimetric analyses of PALF, epoxy and PALF based epoxy composite of non-radiated and irradiated composites materials were investigated. The thermogram of composite material was different than matrix materials as well as reinforced materials. The surface morphology of the reinforced, matrix and composite materials were investigated using scanning electron microscope (SEM).

Abstract: Malaria and HIV share common determinants of vulnerability and, HIV/HCV coinfection accelerates the progression to AIDS causing millions of deaths each year worldwide. The aim of the study was to determine epidemiological and immunological profile of HIV in HCV and Plasmodium coinfection context. All adults (≥ 17 years) volunteers for HIV testing and attending the Voluntary Testing Center of Douala Laquintinie Hospital were consecutively recruited over a period of seven months. Anonymous questionnaire was used to explore demographics, circumstances and reasons for testing, knowledge, attitudes, and behaviors. HIV diagnosis were performed using Rapid Diagnostic Test (RDT) and ELISA, whereas RDT were used for HCV and Plasmodium falciparum infection diagnosis. Quantification of HIV-1 specific CD4 and transaminases were based on FACS Count and spectrophotometer respectively. Overall, 25.6%, 6.4% and 24.8% of 125 adults had HIV, HCV and Plasmodium infection respectively. HIV/Plasmodium, HCV/Plasmodium and HIV/HCV coinfection was reported in 9, 2 and 1 consultant(s) respectively. Based on the WHO classification, severe immunosuppression (CD4 count < 200 cells/mm3) was recorded in HIV and Plasmodium monoinfected individuals: 12.5% and 6.6% respectively. For HIV mono-infected consultants, 12.5% were highly immunocompromised and 43.75% had a CD4 count between 500 and 2000 cells/mm3. Severe immunosuppression was more marked in HIV/Plasmodium (22.2%). HIV and Plasmodium mono-infected patients had higher hyperparasitemia compared to non-infected and the same result was observed with HCV/Plasmodium co-infected patients (42.8%) and HCV/Plasmodium co-infected patients. Severe immunosuppression was recorded in both HIV and Plasmodium monoinfected individuals. This severe immunosuppression was more pronounced in HIV/Plasmodium and HIV/HCV/Plasmodium coinfected patients. HIV and Plasmodium mono-infected patients had more pronounced hypertransaminasemia in women than in men.

Abstract: The grain physical, milling process, and technological characteristics of bread wheat are very crucial for the end-use quality of bread. Nowadays, there is an increasing demand among consumers for bread that contains not only traditional nutrients but also provides other compounds that are beneficial to health and well-being. This review was mainly focused on the impact of the wheat milling process on the quality of wheat-based food products. According to some literature reviews, it was indicated that wheat flour particle size is the major thing that can affect the sensory attributes, nutritional value, and functional properties of wheat-based food products. Four Particles size and wheat milling process steps such as cleaning, and tempering were indicated as factors affecting the color, texture, and acceptance of food products. In this review, there was also found a gap in considering the impact of the wheat milling process, and particle size. In the future research area, the researcher should include the effect of the milling process and particle size during new food product development, standardization of Ethiopian traditional food products, food process, and ingredients optimization, and blending of different proportions of cereals to attain better cereals based food products. Therefore, working on wheat milling process including other agronomic and disease resistance activities is very important.
