Perceived work-related stress and associated factors among the surgical workforce in a Nigerian tertiary health facility: A cross-sectional study.

Healthcare workers continue to experience high levels of work-related stress which continue to negatively affect their psychological, physical, and emotional well-being. This is even more prevalent among healthcare workers who work in surgical specialities, with the surgical operation room becoming a known stressor at hospitals. This study aims to assess work-related stress among surgical team members at Ahmadu Bello University Teaching Hospital in Zaria between January 2021-2022.

Recent Progress on the Gold-Free Integration of Ternary III-As Antimonide Nanowires Directly on Silicon.

During the last few years, there has been renewed interest in the monolithic integration of gold-free, Ternary III-As Antimonide (III-As-Sb) compound semiconductor materials on complementary metal-oxide-semiconductor (CMOS)-compatible silicon substrate to exploit its scalability, and relative abundance in high-performance and cost-effective integrated circuits based on the well-established technology. Ternary III-As-Sb nanowires (NWs) hold enormous promise for the fabrication of high-performance optoelectronic nanodevices with tunable bandgap. However, the direct epitaxial growth of gold-free ternary III-As-Sb NWs on silicon is extremely challenging, due to the surfactant effect of Sb.

Photoluminescence Characteristics of Zinc Blende InAs Nanowires.

A detailed understanding of the optical properties of self-catalysed (SC), zinc blende (ZB) dominant, nanowires (NWs) is crucial for the development of functional and impurity-free nanodevices. Despite the fact that SC InAs NWs mostly crystallize in the WZ/ZB phase, there are very limited reports on the photoluminescence (PL) properties of ZB InAs NWs. Here, we report on the PL properties of Molecular Beam Epitaxy grown, SC InAs NWs.

Current Status of Mental Health Services at the Primary Healthcare Level in Northern Nigeria.

Mental health services at the primary healthcare level remain critical in most developing countries, especially in resource-poor and crisis-stricken communities. This study explored the erstwhile mental health services, with particular reference to their availability, at the 47 primary healthcare centres in three selected states in northern Nigeria, with a view to drawing for action. Qualitative data were collected from a purposive sample of 13 participants through in-depth interviews.

Optimization of self-catalyzed InAs Nanowires on flexible graphite for photovoltaic infrared photodetectors.

The recent discovery of flexible graphene monolayers has triggered extensive research interest for the development of III-V/graphene functional hybrid heterostructures. In order to fully exploit their enormous potential in device applications, it is essential to optimize epitaxial growth for the precise control of nanowire geometry and density. Herein, we present a comprehensive growth study of InAs nanowires on graphitic substrates by molecular beam epitaxy.
