There was no association between breed, sex or age with T. evansi infection. Results of this study provide baseline information that will be useful for launching control programmes in the region and potentially elsewhere.The first known severe disease caused by a coronavirus (CoV) in humans emerged with the severe acute respiratory syndrome (SARS) epidemic in China, which killed 774 people during its 2002/2003 outbreak. The Middle East respiratory syndrome (MERS) was the second human fatal disease, which started in 2012 in Saudi Arabia and resulted in 858 fatalities. AC1-001 In December 2019, a new virus, SARS-CoV-2 (COVID-19), originating from China, began generating headlines worldwide because of the unprecedented speed of its transmission; 5.2 million people were infected and 338 480 had been reported dead from December 2019 to May 2020. These human coronaviruses are believed to have an animal origin and had reached humans through species jump. Coronaviruses are well known for their high frequency of recombination and high mutation rates, allowing them to adapt to new hosts and ecological niches. This review summarises existing information on what is currently known on the role of wild and domesticated animals and discussions on whether they are the natural reservoir/amplifiers hosts or incidental hosts of CoVs. Results of experimental infection and transmission using different wild, domesticated and pet animals are also reviewed. The need for a One Health approach in implementing measures and practices is highlighted to improve human health and reduce the emergence of pandemics from these zoonotic viruses.

Young adults living with mental illnesses often experience a flood of powerful negative emotions, including anger, anxiety, and depression. Some of these young adults remain trapped in those negative emotions long after the stressful events that caused them have passed, while resilient young adults without mental illness are able to quickly bounce back to their normal emotional state.

The objective of the study was to explore social support of young adults living with mental illnesses in the City of Tshwane.

This was a qualitative explorative study done in the City of Tshwane in 2018 among young adults living with mental illnesses, using a semi-structured interview schedule.

Those young adults living with mental illness who had support from family and friends were able to cope with stressful challenges and had a better outlook for the future, while those who perceived their relationship with friends and family as not supportive reported low self-esteem and difficulties dealing with challenging and stressful situations in their lives.

Resilience was seen in those young people living with mental illness with support from family and friends, who had positive future prospects, those with high self-esteem, and those who were able to adapt to changing situations beyond their control.

In light of current economic prosperity and subsequent attainment of upper-middle-income country status, Botswana attracted nurse educators from other African countries. Within this cross-cultural environment, anti-immigrant sentiments have catalysed incidents of incivility, affecting the quality of teaching and learning outcomes.

The aim of this study was to explore experiences of incivility amongst foreign nurse educators and how it impacts their work and livelihood.

This study employed a qualitative approach, using interpretive phenomenology. In-depth interviews using a developed guide were conducted with 13 foreign nurse educators working as nurse educators in Botswana. Thematic analysis was conducted in accordance with interpretive phenomenology, where transcriptions were drafted after each interview.

Three themes emerged from the study findings hostile behaviour, discrimination and inequitable application of procedures and processes. Discrimination as a theme has two sub-themes, namely, workplacemployed to meet the shortage of nurse educators in Botswana. The researchers are of the opinion that the nurse educator shortage will persist in Botswana, partly because of the nursing profession rendered unattractive by hostile social interactions amongst nurse educators' exclusion of foreign nurses from benefits enjoyed by local nurse educators, workplace injustice targeting foreign nurse educators, as well as inequitable application of policies and processes that affect foreign nurse educators.The nitroso group served as a traceless directing group for the C-H functionalization of N-alkylanilines, ultimately removed after functioning either as an internal oxidant or under subsequent reducing conditions. The unique ability of o-NQ catalysts to aerobically oxidize the N-alkylanilines without using solvents and stoichiometric amounts of oxidants has rendered the new opportunity to develop the telescoped catalyst systems without a need for directly handling the hazardous N-nitroso compounds.Recent studies on the structure and transport behaviors of water confined within lamellar graphene have attracted intense interest in filtration technology, but the mechanism of water transport in complex membrane nanostructures remains an open question. For example, similar systems but at much larger scales have indicated that the instabilities of an elastic structure, such as snap-through, play an essential role in controlling the fluid flow. Graphene sheets, which have an atomic thickness, often appear highly wrinkled in nanofluidic devices and so are vulnerable to elastic instabilities. However, it remains unclear how does the flexible wrinkled structure affect the transport of water and filtration efficiency or whether such an effect can be exploited in devices. In this work, we explore the flow-induced snap-through in graphene nanochannels by combining molecular simulations with the theoretical analysis. We further demonstrate its applications to passive control of fluid flow and to ion/molecule selection.
