Human bodies encompass very important symbiotic and mutualistic relationships with tiny creatures known as microbiota. Trillions of these tiny creatures including protozoa, viruses, bacteria, and fungi are present in and on our bodies. They play important roles in various physiological mechanisms of our bodies. In return, our bodies provide them with the habitat and food necessary for their survival. In this review, we comprehend the gut microbial species present in various regions of the gut. We can get benefits from microbiota only if they are present in appropriate concentrations, as if their concentration is altered, it will lead to dysbiosis of microbiota which further contributes to various health ailments. The composition, diversity, and functionality of gut microbiota do not remain static throughout life as they keep on changing over time. In this review, we also reviewed the various biotic and abiotic factors influencing the quantity and quality of these microbiota. These factors serve a significant role in shaping the gut microbiota population.

Purpose: The purpose the study was to investigate the social cultural and environmental related factors influencing the selection of areas of residence in Kenya in the case of Nairobi residents.Methodology: The researcher used descriptive research design. The scope of the study was limited to Nairobi County. The study identified a population of 985,016 households in Nairobi County out of which a sample of 150 respondents were used. Random sampling technique was used to select the respondents from each category. The study used primary data that was collected using questionnaires. Data was analyzed using Statistical Package for Social Sciences (SPSS). The data was then analysed in terms of descriptive statistics like frequencies and percentages.Results: Results indicated that majority of the respondents found social-cultural factors such as safe neighborhood, relations with neighbors, nearness to family and friends, noise level, degree of crowding, size of household, social class and quality of schools in the neighborhood as being important while choosing their places of residence. The results indicated that the most important social cultural factor is quality of schools in the neighbourhood, followed by safety of neighbourhood, degree of crowding, and social class. The least ranked factors were relations with neighbors, community stability, nearness to family and friends, noise level, and size of household. Results indicated that majority of the respondents attached a lot of importance to environmental factors while choosing their places of residence since most of them disagreed with the statement that they would live in an area with poor drainage systems. On the other hand, majority of the respondents agreed to the statements that cleanliness of the neighborhood was important, running water is important, they would pay more for houses that conserve the environment such as energy-efficient housing, knowledge of the materials used to construct a house is necessary.Unique contribution to theory, practice and policy: The study recommended that that social-cultural factors are very important aspects to consider when choosing place of residence. Therefore, it is advisable to take note of such factors as safe neighbourhood, degree of crowding among others before concluding on where to reside. It is also recommended that it would be significant to prioritize environmental factors such as drainage systems, availability of running water, and cleanliness of the neighbourhood among other environmental factors while concluding a decision on where to reside. It is also recommended that landlords should put into consideration such factors since majority of their potential tenants’ decision to reside in a given area will in most cases be influenced by such factors.

In the production process of photovoltaic modules, there are defects of bad welding, defects in the raw material, degradation by environmental factors, as well as bad handling of the material or lack of maintenance, affecting the quality of the product. The omission of control of the temperature in the welding process causes the defect called cut fingers, which consists of the rupture presented by the collectors of the cell. The present research focused on studying the factors that influence the welding process for the generation of cut fingers, emphasizing the temperature measurement during the welding process. The methodology used consisted of describing the materials involved in the welding process and monitoring the temperature in the welding machine, as well as the ambient temperature. Some cells without solder were found. The temperature variation in the welding heads ranged from -14.9 to -121 ° C. With this study it is concluded that the temperature of the welding heads should continue to be monitored, since the variation is out of specification, the pH of the fluss must be verified, and the periodicity of its distillation must be determined to purify it and be able to reuse it.

Abstract The global prevalence of obesity has been rising at an alarming rate, accompanied by an increase in both childhood and maternal obesity. The concept of metabolic programming is highly topical, and in this context, describes a predisposition of offspring of obese mothers to the development of obesity independent of environmental factors. Research published in this issue of Clinical Science conducted by Litzenburger and colleagues (Clin. Sci. (Lond.) (2020) 134, 921–939) have identified sex-dependent differences in metabolic programming and identify putative signaling pathways involved in the differential phenotype of adipose tissue between males and females. Delineating the distinction between metabolically healthy and unhealthy obesity is a topic of emerging interest, and the precise nature of adipocytes are key to pathogenesis, independent of adipose tissue volume.
