Popular (i.e., nonclassical) musicians have higher rates of depression, anxiety, and alcohol misuse than the general population. In this study, occupational and financial stresses were hypothesized to be associated with depression, anxiety, and alcoh

OBJECTIVE: Popular (i.e., nonclassical) musicians have higher rates of depression, anxiety, and suicide than the general population. Occupational and financial stress have been suggested to be social determinants of musician mental health burden. A p

Water cannot be completely removed from ethanol by distillation because of the presence of the minimum azeotrope. Ethanol can be readily dehydrated by using extractive distillation in which the water is removed as overhead product and the ethanol and

The lower fatty acids cannot be readily separated from water by distillation. Formic acid forms a maximum azeotrope with water, acetic acid boils very close to water and propionic acid forms a minimum azeotrope with water. These acids can be easily s
