In this paper, technical and economic prerequisites to attain reduced carbon dioxide (CO2) emissions through the use of biomass-based energy carriers in the transportation sector are studied. CO2 emission reduction per unit of land used for biomass production as well as costs for CO2 emission reduction are estimated when substituting rape methyl ester, biogas from lucerne, ethanol from wheat and e

Social and ethical issues in the supply chain are gaining importance in all types of organizations. Therefore some public and private organizations have already started to introduce socially responsible purchasing practices. However, current practices are limited and seem unsystematic. There is also a difference between few front-running organizations and the rest. It is therefore useful at this e

High achievement in school has been associated with increased risk of eating disorders, including anorexia nervosa (AN) and bulimia nervosa (BN), but causality of these relationships is unclear. We sought to examine the association between school achievement and AN or BN in a national cohort and to determine the possible contribution of familial confounding using a co-relative design.

Risk for drug abuse (DA) is strongly associated with neighborhood social deprivation (SD). However, the causal nature of this relationship is unclear.

The β-lactamase genes of Haemophilus influenzae are commonly positioned on large integrative and conjugative elements, but a group of blaTEM-carrying small plasmids (4000-6000 bp) with a common structural backbone have recently been characterized. In this study we investigated the epidemiological significance and potential for transfer of this group of small plasmids.

The present study investigates the dental work in terms of time distribution and mechanical exposure in value-adding work (VAW) and non-VAW. Further rationalisation of dental work would typically involve an increase in the proportion of VAW. Information on mechanical exposure within the classes of VAW and non-VAW may be used to predict possible implications of rationalisation. Sixteen dentists wer

Different types of accumulated stress have been found to have negative consequences for immigrants' capacity to adapt to the new environment. It remains unclear which factors have the greatest influence.

The aim was to develop a new instrument for measuring length of sleep as well as television and computer habits in school-age children. A questionnaire was constructed for use when children visit the school health care unit. Three aspects of the validity of the questionnaire were examined: its face validity, content validity, and construct validity. Test-retest reliability was assessed by giving t

BACKGROUND: It is unclear which anthropometric measure is most useful for assessment of the cardiovascular risk. We investigated the association between different anthropometric measures and risk of heart failure (HF) hospitalization. METHODS: BMI, waist-hip ratio (WHR), waist circumference (WC), body fat percentage (BF%), weight and height were measured among 26 653 subjects (aged 45-73 years) wi

This article describes the results to expand and develop the use of the Satisfaction with Daily Occupations (SDO-13) Scale. Data were collected in primary care before (I) and after intervention (II) among clients with stress-related disorders and musculoskeletal pain. The Cronbach's alpha values of the SDO-13 Scale were 0.80 and 0.88. Convergent validity was assessed against global occupational sa

The purpose of this study was to clarify the causes of the smoking-schizophrenia association.
