U.S. State-Level Containment Policies Not Associated with Food Insecurity Changes During the Early COVID-19 Pandemic: A Multi-level Analysis.

Objective: To investigate the relationship between United States (US) containment measures during the COVID-19 pandemic and household food insecurity.

Design: To investigate these relationships, we developed a framework linking COVID-related containment policies with different domains of food security, then used multilevel random effects models to examine associations between state-level containment policies and household food security. Our framework depicts theorized linkages between stringency policies and five domains of food security (availability, physical access, economic access, acceptability in meeting preferences, and agency, which includes both self-efficacy and infrastructure).

Experimental studies of particle removal and probability of COVID-19 infection in passenger railcars.

A series of experiments in stationary and moving passenger railcars was conducted to measure the removal rates of particles in the size ranges of SARS-CoV-2 viral aerosols, and the air changes per hour provided by the existing and modified air handling systems. The effect of ventilation and air filtration systems on removal rates and their effects on estimated probability (i.e.

Beetroot improves oxidative stability and functional properties of processed foods: singular and combined effects with chocolate.

Oxidation is a significant problem in processed foods affecting their physico-chemical, shelf life and health properties. Natural antioxidants could be viable alternatives to synthetic variants for safely improving antioxidation properties of processed foods. The aim of this study was to assess the singular and combined effects of beetroot and chocolate on the oxidative stability of a high fat and protein processed food (sponge cake) during storage and gastrointestinal digestion.

Clay mineral type effect on bacterial enteropathogen survival in soil.

Enteropathogens released into the environment can represent a serious risk to public health. Soil clay content has long been known to have an important effect on enteropathogen survival in soil, generally enhancing survival. However, clay mineral composition in soils varies, and different clay minerals have specific physiochemical properties that would be expected to impact differentially on survival.
