The Impact

Natural processes along with increased industrial production and the irresponsible behavior of mankind have resulted in environmental pollution. Environmental pollutants can be categorized based on their characteristics and appearance into the following groups: physical, biological, and chemical. Every single one of them represents a serious threat to the male reproductive tract despite the different modes of action. Male gonads and gametes are especially vulnerable to the effect of exogenous factors; therefore, they are considered a reliable indicator of environmental pollution. The impact of xenobiotics or radiation leads to an irreversible impairment of fertility displayed by histological changes, modulated androgen production, or compromised spermatozoa (or germ cells) quality. The present article reviews the exogenous threats, male reproductive system, the mode of action, and overall impact on the reproductive health of humans and animals.

Background. Recently, the importance of the gut microbiota in the pathogenesis of several disorders has gained clinical interests. Among exogenous factors affecting gut microbiome, diet appears to have the largest effect. Fatty acids, especially omega-3 polyunsaturated, ameliorate a range of several diseases, including cardiometabolic and inflammatory and cancer. Fatty acids associated beneficial effects may be mediated, to an important extent, through changes in gut microbiota composition. We sought to understand the changes of the gut microbiota in response to an omega-3 rich diet.Case Presentation.This case study investigated changes of gut microbiota with an omega-3 rich diet. Fecal samples were collected from a 45-year-old male who consumed 600 mg of omega-3 daily for 14 days. After the intervention, species diversity was decreased, but several butyrate-producing bacteria increased. There was an important decrease inFaecalibacterium prausnitziiandAkkermansiaspp. Gut microbiota changes were reverted after the 14-day washout. Conclusion. Some of the health-related benefits of omega-3 may be due, in part, to increases in butyrate-producing bacteria. These findings may shed light on the mechanisms explaining the effects of omega-3 in several chronic diseases and may also serve as an existing foundation for tailoring personalized medical treatments.

Purpose The purpose of this paper is to investigate the high failure among African entrepreneurs post-2008 financial crisis. It evaluates the evidence of actual and perceived disadvantage and endogenous and exogenous factors affecting black and minority ethnic businesses. Design/methodology/approach The research is based on an interpretivist frame which uses a dialogic methodology. It uses in-depth interviews. The researchers framed discussion questions so as to invite the participants to articulate directly their experiences for the benefit of the readership, other existing African businesses and aspiring entrepreneurs. Findings The findings from the interviews with 20 leaders of “dead” businesses indicate the impact that place, people and poverty have on business failure and identify reasons for African business failure rates compared to other minorities. This study reveals that culture, an often understated variable, is critical in understanding the deeper reasons for the under-performance of African small entrepreneurs and its impacts on individual and collective lives. Practical implications Recovery solutions ought to be formulated from participants’ call for diversification, inter-cultural learning and integration as potential remedies. The research addresses the socio-economic problems encountered by owners of “dead” businesses. Policymakers and financial organisations ought to pay heed to the skills and resources that minorities offer as part of remedies for future enterprises. Originality/value Studies on failed African businesses are under-represented in the literature. This study identifies the important role of culture on the failure of small businesses owned by African migrants in the UK. It highlights the significant socio-economic and situational barriers that they navigate in quest for recognition and cultural integration through business endeavours.

The article outlines some human factors affecting the operation and safety of passenger air transport given the massive increase in the use of the VLA. Decrease of the impact of the CO2 world emissions is one of the key goals for the new aircraft design. The main wave is going to reduce the burned fuel. Therefore, the eco-efficiency engines combined with reasonable economic operation of the aircraft are very important from an aviation perspective. The prediction for the year 2030 says that about 90% of people, which will use long-haul flights to fly between big cities. So, the A380 was designed exactly for this time period, with a focus on the right capacity, right operating cost and right fuel burn per seat. There is no aircraft today with better fuel burn combined with eco-efficiency per seat, than the A380. The very large aircrafts (VLAs) are the future of the commercial passenger aviation. Operating cost versus safety or CO2 emissions versus increasing automation inside the new generation aircraft. Almost 80% of the world aircraft accidents are caused by human error based on wrong action, reaction or final decision of pilots, the catastrophic failures of aircraft systems, or air traffic control errors are not so frequent. So, we are at the beginning of a new age in passenger aviation and the role of the human factor is more important than ever.
