Effect of Risk Mitigation Guidance opioid and stimulant dispensations on mortality and acute care visits during dual public health emergencies: retrospective cohort study.

Objective: To determine the effect of opioid and stimulant Risk Mitigation Guidance (RMG) dispensations on mortality and acute care visits during the dual public health emergencies of overdose and covid-19.

Design: Population based retrospective cohort study.

Setting: British Columbia, Canada.

Topological Analysis of the Interactions between Organic Molecules and Co(Ni)MoS Catalytic Active Phases.

The adsorption modes of toluene, 2,3-dimethylbut-1-ene, and 2-methylthiophene on the edges of Co(Ni)MoS nanocrystallites has been investigated with the ELF topological approach of chemical bonding. The chemisorbed modes are characterized by the formation of bonding basins linking the substrate to the catalytic sites. The electronic rearrangements within the substrate are discussed.
