Abstract:
According to the Centers for Disease Control and Prevention, suicide is the second leading cause of death in American teenagers, and is a growing public health concern. This study uses multivariable logistic regression to investigate the independent relationship between suicide ideation and sleep duration in teenagers using the 2015 Youth Behavior Risk Surveillance Study, controlling for demographic, behavioral, and other factors found to be associated. Sleep durations of 4-5 hours and 6-7 hours per night were associated with approximately 75-80% and 20-40% increased adjusted odds of suicide ideation, as compared to teens sleeping the recommended 8 hours or more, and should be considered as a potential important indicator for adolescent suicidal ideation in primary-care screens.

Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
