Abstract Background In North America, opioid use has become a public health crisis with policy makers declaring it a state of emergency.Opioid substitution therapy (OST) is a harm-reduction method used in treating opioid use disorder.While OST has shown to be successful in improving treatment outcomes, there is still a great degree of variability a
Biodiesel is one of diesel fuel alternative made from renewable resources such as vegetable oils and animal fats.One of the natural ingredients that can be used as a material in the production of biodiesel is waste cooking oil (WCO).Biodiesel from WCO can be made through a transesterification reaction using a CaO catalyst.Free fatty acid (FFA) cont
The continental deep subsurface is likely the largest reservoir of biofilm-based microbial biomass on Earth, but the role of mineral selectivity in regulating its distribution and diversity is unclear.Minerals can produce hotspots for intraterrestrial life by locally enhancing biofilm biomass.Metabolic transformations of minerals by subsurface biof
