Rock crack initiation triggered by energy digestion.

The critical value of rock failure is determined by irreversible deformation (inelastic deformation, damage, and other internal dissipation) processes and external conditions before rock failure. Nevertheless, a thorough explanation of the mechanism causing cracks in rock material has not yet been provided. The strain energy theory is applied in this work to assess the initiation of rock cracks and investigate the relationship between energy digestion and rock strength.

Rural Friendship Bench: A qualitative study in Zaka district, Zimbabwe.

Background: We piloted the Friendship Bench-an evidence-based, urban-area task sharing intervention for common mental disorders-in rural Zimbabwe. The intervention combines problem solving therapy with income generating activities. This study sought to understand the intervention's implementation in terms of acceptability, feasibility, and sustainability as well as local attitudes towards mental wellbeing in rural Zimbabwe.

Symptoms of common mental disorders and adherence to antiretroviral therapy among adults living with HIV in rural Zimbabwe: a cross-sectional study.

Objectives: To examine the proportion of people living with HIV who screen positive for common mental disorders (CMD) and the associations between CMD and self-reported adherence to antiretroviral therapy (ART).

Setting: Sixteen government-funded health facilities in the rural Bikita district of Zimbabwe.

Design: Cross-sectional study.

Acute hepatitis B virus infection model within the host incorporating immune cells and cytokine responses.

We formulate and analyze a within-host hepatitis B viral mathematical model for hepatitis B in the acute phase of infection. The model incorporates hepatocytes, hepatitis B virus, immune system cells and cytokine dynamics using a system of ordinary differential equations. We use the model to demonstrate the trends of the hepatitis B infection qualitatively without the effects of immune cells and cytokines.

Perceptions of HIV-related trauma in people living with HIV in Zimbabwe's Friendship Bench Program: A qualitative analysis of counselors' and clients' experiences.

This study investigated the experience of lay health workers (LHWs) delivering problem-solving therapy (PST) for common mental disorders (CMD) as well as clients' views of the PST program referred to as the Friendship Bench (FB). Semi-structured interviews were conducted with LHWs (n = 5) and clients living with HIV (PLWH) (n = 10). Data were analyzed using thematic content analysis.
