Analysis of the optimum pH and salinity conditions for the cultivation and biomass production of Chlorella vulgaris from cassava waste

Biofuel serves as an alternative energy to the common fossil fuels currently in use globally and are drawing increasing attention worldwide as substitutes for petroleum-derived transportation fuels to help address challenges associated with petroleum derived fuels. Third generation biofuels, also termed advanced biofuels, are produced from fast growing microalgae and are potential replacements for conventional fuels. The growth and biomass production of these microalgae is dependent on the conditions they are cultivated such as pH and Salinity. Cassava waste mixtures were cultivated on Chlorella vulgaris stock culture at different concentration ratio at ambient temperature, natural light and dark conditions at 670nm absorbance for 14 days. Optimum growth was obtained at 160:40 for cassava peel water to cassava waste water CP:CW. pH variations 6.0, 6.5, 7.0, 7.5, 8.0, 8.5 and 9.0 were checked to determine the optimum pH for the growth and biomass production of Chlorella vulgaris on the optimum cassava waste mixture concentration. It revealed that at pH 6.5, optimal growth and biomass production was achieved, minimal growth was observed at pH 8.0 while minimal biomass was produced at pH 9.0. Salinity variations of 5, 10, 15, 20, 25, 30, 35 and 40 mg/l were used to determine the growth response and biomass production of Chlorella vulgaris. It revealed that salinity variation at 10ppm will be necessary for highest growth on the cassava waste as well as in biomass production. The use of optimal pH and salinity can significantly increase biomass production thus enhancing biofuel production.

Parameters observed were plant height, number of leaves, leaf length, leaf width, root length, fresh weight, root volume and weight fit for consumption. The results showed that the administration of 50% AB mix + 50% LOF of tofu liquid waste and 25% AB mix + 75% LOF of tofu liquid waste showed results that tended to be the same but the results of the combination of 75% AB mix + 25% LOF of tofu liquid waste were higher. On the parameters of the number of leaves is 11.12 strands, fresh weight is 66.40 g and suitable weight for consumption is 58.31 g.

Cytokine storm interference

Viral infections are a natural and inevitable part of life. In healthy individuals, mortality increases when the body’s innate immune system quickly activates, creating a cytokine storm. A rapid and excessive release of cytokines into the bloodstream can cause acute respiratory distress syndrome and death. This communication proposes inhibiting cytokine storm development through forced atopy. Hyper-allergenic skin cream therapy stimulates adaptive immunity to support innate immunity before acute infection.

Medical waste management in healthcare institutions

Studies over the past decade have shown that medical waste generated has increased significantly and will continue to increase with the pandemic. To identify solutions to solve this global issue, the assignment focuses on defining the existing waste management practices followed in developing countries and highlights specific challenges faced. The purpose of this assignment is to identify ways where healthcare organizations can improve the overall medical waste management (MWM) process and create awareness among co-workers. The assignment is divided into three main components where critical analysis of primary research, policy for waste management and use of IT/IS tools were analyzed. Three articles analyzed in this assignment were published in high impact journals/international reports between 2014-2018. Findings from the primary research were obtained using a Likert-scale questionnaire from 156 healthcare institutions, the results indicated that MWM practices followed in healthcare institutions are impacted by three factors, awareness of staff, technological availability and attitudes of top-board management. The three factors had a p-value of 0.00 in the correlation analysis carried out indicating a highly significant relationship between them. Integrated sustainable waste management model following the GWMO (Global Waste Management Outlook) framework was identified to be most adaptable method. The advantage of this model is such that it can be remodeled based on the country’s requirement with the help of digital tools and country-level indicators. The use of IT/IS tools were critically analyzed in the last article with use of GIS integrated real-time waste management system being identified as the most feasible option, where using online tracking systems and smart bins the type of waste and quantities produced can be measured and provide real time updates to local authorities to ensure safe waste management practices are followed. Recommendations from the assignment identifies that countries needs to conduct a preliminary analysis of types of medical waste being generated in healthcare institutions to provide a better understanding of types of hazardous waste exposed to the environment. Additionally, frequent training workshops needs to be conducted to ensure the management and staff understand the importance of MWM.

Physico-chemical and microbiological characteristics of water for domestic use in Cotonou in the republic of Benin

Water is the source of life. It is essential for the survival of all living things. However, its alteration becomes harmful to humans. In Cotonou, the main city of Benin, the quality of drinking water is worrying because of many factors such as environmental pollution and poor hygiene around water sources. In fact, poorly ecological management methods of household waste pose risks of contamination of soil and water resources. This study aims to assess the quality of domestic water for households in the city of Cotonou. The methodology adopted is summed up in a physico-chemical and microbiological analysis of thirty water samples taken from households in the 13 districts of the city of Cotonou. The results obtained at the physicochemical level show that, apart from the waters of SONEB at the source, whose turbidity (5.6 NTU) complies with the standard which is 5 NTU, that of other sources is much greater than Standard. This indicates the presence of suspended solids in the water that may harbor microorganisms harmful to humans. With regard to microbiological quality, all the water sampled at household level contains E.Coli, the number of which is much higher than the Benin standard which sets at 0/1 ml of water. In addition, the water sampled from the wells contains high numbers of fecal coliforms. As for SONEB water, the presence of coliforms was determined but with lower numbers than well water (50 / ml at household level and 2 / ml at source level.

It involves examining the exfoliated buccal cells for alterations in cellular and nuclear features. It offers the advantage of being useful in less resource setting areas. Though associated with many false results, the newer technological advancements have proven its diagnostic efficiency. Oral exfoliative cytology can readily be used as adjunct to disease diagnosis, however, it cannot replace biopsy.

Influence of parity and Body Mass Index (BMI) on endometry thickness variation in women of Lokossa, Benin

The thickness of the endometrium is also an important parameter in the clinical management of women. It is often influenced by several parameters which are important to determine. This is why the present study looked at the factors that influence the variation in the thickness of the endometrium of women in Lokossa in the Republic of Benin. This descriptive, prospective and cross-sectional study concerns 166 women aged 15 to 40 in Lokossa. Ultrasound examination measured the thickness of the endometrium on the longitudinal section through the suprapubic route. Anthropometric parameters were taken by other equipment from each woman. Analysis of one-way proc glm ANOVA variants and Student-Newman-Keuls (SNK) tests identified factors associated with variation in endometrial thickness in women. At the end of the study, the minimum, average and maximum values ​​of the thickness of the endometrium obtained are respectively Vm = 3.50 mm, VMoy = 6.73 ± 1.38 mm, MV = 10.00 mm during the pre-ovulatory phase, Vm = 7.30 mm, MV avg = 10.75 ± 2.11 mm, MV = 16.00 mm during the post-ovulatory period. There is an association between the thickness of the endometrium and parameters such as age, weight, Body Mass Index, parity. BMI has been found to be associated with changes in endometrial thickness. And this variation in the thickness of the endometrium of the woman's uterus is related to the number of deliveries. Thus, the higher the number of childbirth, the greater the thickness of the endometrium deprived.
