Vibrio parahaemolyticus is a Gram-negative, halophilic bacterium isolated from marine environments globally. After the consumption of contaminated seafood, V. parahaemolyticus causes acute gastroenteritis. To initiate infection, a wide range of virulence factors are required. A complex group of genes is known to participate in the pathogenicity of V. parahaemolyticus; however, to understand the full mechanism of infection, extensive research is yet required. V. parahaemolyticus has become the leading cause of seafood-related gastroenteritis in Japan, the United States and several other parts of the world. In addition, outbreaks caused by the pandemic clone of this organism are escalating and spreading universally. To minimize the risk of V. parahaemolyticus infection and warrant the safety of seafood, collaboration between governments and scientists is required. We herein provide an updated review of the pathogenicity determinants and distribution of V. parahaemolyticus to deliver a better understanding of the significance of V. parahaemolyticus and its host–pathogen interactions.

The study included two hundred thirty-four participants; all participants with a chronic disease but not infected with COVID -19 were between 24 and 65 years of age. Residents of the study area were randomly selected. Descriptive statistics and a t-test were used for associations with a p-value of 0.05 or less.Results: This study found that anxiety rated by GAD 7 was either mild (18, 7.7%), moderate (98, 41.9%), or severe (41, 17.5%) among participants. PHQ 9-rated depression showed 22 (9.4%) mild depression, most of them in participants aged 36– 44 years. Participants with kidney disease showed major depression 11 (42.31%). Factors that significantly affected anxiety scores were age 24– 35 years (P =0.002), university graduates (P < 0.000), married (P < 0.000), those with diabetes and hypertension (P =0.041), and urban residents (P < 0.023). Those who had secondary education were married and smoked were significantly more likely to have major depression than those with another educational status (p < 0.05).Conclusion: COVID 19 pandemic had a significant impact on the psyche of uninfected people with chronic diseases in Sudan, and significant associated factors were identified. Unique interventions are strongly recommended to reduce the psychological impact of the COVID 19 pandemic.Keywords: COVID-19, psychological impact, chronic disease, anxiety, depression

Technological advancement in automobile and infrastructure sector encourages more and longer distance travel and the way people travel to perform their daily tasks creates environmental problems. Activity-travel behavior of individual have a significant potential to be influenced to reduce environmental issues, however, the underlying factors need to be investigated. This paper investigates pro-environmental activity-travel behavior using recorded GPS-based travel-activity diaries and individual personal traits using online questionnaire and estimating a structure equation model borrowed from theory of planned behavior. The results of the study verified that individual mobility decisions were highly influenced by the attitude one has about specific travel behavior. The results are helpful in devising effective behavioral intervention. (C) 2019 The Authors.

In this study, rigid polyurethane foams (RPUF) were successfully modified using 30 wt.% aluminium hydroxides (ATH), 1.0 pphp silicone surfactant, and different concentrations of graphene, using a one-shot one-step foaming method. This study aims to improve the compressive strength, flame retardancy, and thermal properties of RPUF by creating a synergistic effect between ATH and graphene in fire-retardant RPUF hybrid composites. The effects of a fixed amount of ATH and silicone surfactant and various loadings of graphene on RPUF were investigated. The results show that 0.5 wt.% graphene loading confers the best compression performance on the hybrid composite. Their compressive strength value of 12.58 KPa was higher than virgin RPUF (4.07 KPa) and RPUF/ATH (9.89 KPa). FTIR confirmed the functional groups in the virgin RPUF but could not identify new functional groups in most modified composites. The smallest amount of graphene addition (0.5 wt.%) produced a more stable hybrid composite structure. At 3.0 wt.% graphene addition, the maximum decomposition temperature of the RPUF/ATH hybrid composite was recorded (539oC), which was enhanced by 50% compared to virgin RPUF (296oC), and the highest char residue of 17.46% was observed. The incorporation of graphene enhanced the thermal firmness of the hybrid composite. The study also revealed an enhancement in the fire resistance of the hybrid composite. The LOI and UL-94 results showed that incorporating 3.0 wt.% enables increased LOI value and V-0 classification compared to virgin samples. This hybrid composite can be used in high-performance building insulation applications.

Introduction: Multi-temporal land-use and land-cover data provides a historical vehicle for determining and evaluating long-term trends in bio-physical landscapes. Land-use and land-cover assessment and mapping is one of the most useful applications of geographic information system (GIS) for planning, management, and development. This study analyses the spatio-temporal pattern of forest cover dynamics for three decades in Falgore Game Reserve in Kano, Nigeria. The dynamics of forest cover transition during 1985–2015 was analysed using multi-temporal Landsat imagery. Results: The spatio-temporal analysis shows that moderate woodland dominated in 1985 (46%) and 2005 (57%) but was replaced by open woodland in 2015 which accounts for 58% of the total area of Falgore Game Reserve (FGR) currently. Dense woodland occupied the least area of the total forest estate that varied between 17% in 1985 and 1% in 2015. The results indicate that dense woodland, moderate woodland, and very open woodland were decreased at annual average rate of 3, 1, and 0.4%. Open woodland had expanded from 21,127 ha in 1985 to 53,392 ha in 2015. The main drivers of forest resource degradation in the area were found to be excessive fuelwood collection, overgrazing, agricultural expansion, and forest fire. Conclusions: These findings suggest that protection strategies employed in FGR were not effective as deforestation is still evident in the reserve. Government and environmental based NGOs should therefore prioritize effective and efficient conservation strategy for present and future use of forest resources, in addition to the provision of alternative livelihood sources to communities proximate to the reserve. This will ensure the socio-economic well-being of the locals and sustainable conservation of biological diversity in the area.

Informational interventions are considered important to bring positive changes in attitudes and perception about pro-environmental life styles among individuals. In relation to mobility aspects, it is vital to identify relatively easier changes that have potential to reduce negative impacts of mobility on environment and individual health. This paper provides a comprehensive methodological framework and developed a computation algorithm that helps identify such an easy changes in the travel behavior of an individual. The development of algorithm is based on a variety of different data sources such as activity-travel diaries and related constraint information, meteorological conditions, bicycle and public transport supply data. A variety of rules that are part of the computational algorithm are taken from the transport modelling literature, where constraints and factors were examined for various activity-travel decisions. Three major aspects of activity-travel behavior such as lesser car use, cold start of car engines and participation in non-mandatory outdoor activities are considered in assessing pro-environmental potential. The algorithm is applied to data collected, using citizens from Hasselt and their pro-environmental potential is determined, which has been found significant. ; This project has received funding from the European Union Horizon 2020 research and innovation programme under grant agreement No 689954.

Africa is the second largest continent and has its socioeconomic and health peculiarities. Countries are faced with varying challenges towards its Universal Health Coverage (UHC) achievement and hence the region requires health system reforms to drive equitable and balanced medical services to its populace. The main objectives of the paper were to explore the complexities of the African health systems, subsequently highlighting major challenges to UHC and to provide a framework for strategic approaches to health system strengthening to ensure realization of UHC. Information presented in this paper was collected from published literature and reports on Rwanda, Kenya, Nigeria, Tanzania, Ghana, Tunisia, Democratic Republic of Congo, Zambia, Egypt and South Africa, amidst other African countries. The published literature points to the presence of a somewhat slow progress towards UHC or at least an existent knowledge of it. However, common challenges faced can be grouped into 1) Financial constraints which include low levels of government expenditure on health and increased out-of-pocket percentages, (2) Lack of coverage of key services which includes majorly immunization rates and existence of health insurance for citizens, (3) Input constraints ranging from drug availability to skilled healthcare workforce, information and research and (4) Lack of political support and commitmenttowards universal health coverage. To overcome the above-stated constraints, two broad groups of interventions were identified; General interventions largely focusing on reprioritization of health budget, quality and improved services, equipped facilities and efficient social protection systems; and Specific interventions which emphasizes the importance of eliminating shortage of health workers, ensuring availability of essential medicines/ products, embracing decentralization at supply chain management, validating data/ information system and advocacy for impactful health education/promotion. Although there will be strength and weakness ...
