Development of Fibre-Reinforced Cementitious Mortar with Mineral Wool and Coconut Fibre.

Globally, as human population and industries grow, so does the creation of agricultural, industrial, and demolition waste. When these wastes are not properly recycled, reused, or disposed of, they pose a threat to the environment. The importance of this study lies in the beneficial use of coconut fibre and mineral wool in the form of fibres in cement mortar production.

Revisiting the Paradox of Smoking: Radioactivity in Tobacco Smoke or Suppressing the SARS-CoV-2 Receptor, Angiotensin-Converting Enzyme 2, via Aryl-Hydrocarbon Receptor Signal?

Despite current controversies, some reports show a paradoxical mitigating effect associated with smoking in individuals with symptomatic COVID-19 compared to the general population. To explain the potential mechanisms behind the lower number of hospitalized COVID-19 patients, it has been hypothesized that cigarette smoking may reduce the odds of cytokine storm and related severe inflammatory responses through cholinergic-mediated anti-inflammatory mechanisms. Japanese scientists have recently identified a potential mechanism behind the lower numbers of COVID-19 cases amongst smokers compared to non-smokers.

Overcoming fear of movement resulting from knee replacement; strategies used by patients: An interview study.

Background And Aims: Fear of movement is among the main concerns of patients following knee replacement surgery and a determining factor in the success of surgery. The strategies adopted by patients to overcome this fear have not yet been identified, but once pin pointed, these strategies can be strengthened and modified through intervention. The aim of the present study was to explore the personal strategies adopted by patients following knee replacement to overcome fear of movement.
