1. 1. Evaluation of a Swedish parental prevention program : youth drunkenness, alcohol-specific parenting and gender differences

   Författare :Anna Strandberg; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Research suggests that alcohol-specific parenting and parental prevention programs can be effective in the efforts to prevent underage drinking. The Örebro prevention program (ÖPP) is based on principles of alcohol-specific parenting and encourages parents to maintain restrictive attitudes towards underage drinking, with the aim to reduce youth drinking and drunkenness.

3. 2. Fuel conversion and ash formation interactions : a thermochemical study on lignocellulosic biomass

   Författare :Anna Strandberg; Markus Broström; Rainer Backman; Christoffer Boman; Maria Zevenhoven; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Char conversion; pyrolysis; devolatilization; ash transformation; biomass; fuel characterization; fuel composition; ash composition; silicate formation; carbonate formation; thermogravimetric analysis; micro-tomography;

   Sammanfattning : Biomass is considered to be CO2 neutral, and to be able to reduce the dependency on fossil fuels the need for expanded and sustainable biomass feedstock is increasing. Ash-related problems are some of the most important aspects of this increasing use of new biomass assortments in thermal energy conversion systems. LÄS MER

4. 3. Framing the water and sanitation challenge : A history of urban water supply and sanitation in Ghana 1909 - 2005

   Författare :Anna Bohman; Lena Andersson-Skog; Urban Strandberg; Björn-Ola Linnér; Umeå universitet; []

   Sammanfattning : This thesis analyses the development of urban water supply and sanitation services in Ghana from 1909 to 2005.  Special focus is put on institutional arrangements with regard to networked, large scale and centrally managed water and sewerage services. LÄS MER

5. 4. Calibration of b-tagging and search for Dark Matter : Calibration of b-tagging efficiency and search for Dark Matter production in association with heavy flavour quarks with the ATLAS experiment

   Författare :Anna Shcherbakova; Sara Strandberg; Oscar Gonzalez Lopez; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS; ATLAS experiment; physics analysis; LHC; Large Hadron Collider; Dark Matter; b-tagging; fysik; Physics;

   Sammanfattning : The Large Hadron Collider (LHC) is the most powerful and complex particle accelerator ever built. The ATLAS and the CMS are the two multipurpose particle detectors at the LHC, designed to cover a wide range of physics measurements. LÄS MER
