Objective:
This study aimed to examine the effects of a school-based alcohol education intervention.
Design:
Two-arm three-wave cluster-randomized controlled trial, with schools as the unit for randomization. Surveys were conducted prior to intervention implementation, then 4 and 12 months after baseline.
Setting:
A total of 30 public schools in Schleswig-Holstein, Germany. Participants Baseline data were obtained from 1686 7th graders. The retention rate was 85% over 12 months. Intervention The intervention consisted of four interactive lessons conducted by teachers, booklets for students and booklets for parents.
Measures:
Knowledge, attitudes, life-time alcohol consumption (ever use alcohol without parental knowledge, ever been drunk and ever binge drinking) and past-month alcohol use.
Results:
Intention-to-treat analyses revealed that intervention status was associated with more general knowledge about alcohol and lower levels of life-time binge drinking. No effects were found with respect to students' self-reported attitudes, intentions to drink, life-time alcohol use and past-month alcohol use.
Conclusions:
The results indicate that this brief school-based intervention had a small short-term preventive effect on alcohol misuse.

Alcohols from Carbonyl Compounds: Reduction
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...

Protection
It defines a protecting group as the masking agent to make the more reactive species inert to a given set of conditions. This concept is depicted via the illustration of liquid flow through different outlets in an assembly of pipes. The analogy helps to understand the role...

Preparation of Alcohols via Addition Reactions
The acid-catalyzed addition of water to the double bond of alkenes is a large-scale industrial method used to synthesize low-molecular-weight alcohols. An acidic atmosphere is required to allow the hydrogen in the water molecule to act as an electrophile and attack the double bond in an alkene. The addition of a proton to the double bond creates a carbocation intermediate. The proton preferentially bonds to the less substituted end of the double bond to create a more stable carbocation...
