   Sammanfattning : European emissions to air of SO2, NOx, PM2.5, NH3 and NMVOC still today cause harm to human health and the environment. These pollutants are associated with the premature death of ~400 000 people annually in the EU (25 000 perished in traffic accidents 2017). Improvements are expected but problems will persist.

4. 3. Chromatin transcription and dietary proteins : with observations on the RNA synthesis of rat liver in response to the protein content and amino acid composition in the diet

   Författare :Stefan U. Åström; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis aims at characterization of fractionated chromatin with respect to bound and free RNA polymerase activities together with an analysis of the in vitro transcription of chromatin after changing the protein or amino acid content of the diet.Rat liver nuclei were incubated with micrococcal nuclease which acts as an endonuclease on DNA.

5. 4. Effects of vibration on muscles in the neck and upper limbs : with focus on occupational terrain vehicle drivers

   Författare :Charlotte Åström; Gunnevi Sundelin; Lage Burström; Stefan Karlsson; Karin Harms-Ringdahl; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electromyography; drivers; hand-arm vibration; trapezius; whole-body vibration; Physiotherapy; Sjukgymnastik fysioterapi;

   Sammanfattning : Introduction: Occupational drivers of terrain vehicles are exposed to several risk factors associated with musculoskeletal symptoms in the lower back as well as in the neck and upper limbs. Vibration has been suggested to be a main risk factor. These drivers are exposed to both whole-body vibration (WBV) and hand-arm vibration (HAV). LÄS MER

7. 5. Included yet Excluded? : Conditions for Inclusive Teaching in Physical Education and Health

   Författare :Peter Åström; Staffan Karp; Simon Wolming; Stefan Lund; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Inclusive teaching; exclusion; physical education and health; motivation; Education; pedagogik;

   Sammanfattning : This dissertation has examined the conditions for teachers who teach Physical Education and Health (PEH) in elementary school (age 11-12) and their opportunities to pursue inclusive teaching with the aim of reaching all pupils. The compilation thesis consists of four different articles and provides knowledge from the perspectives of pupils and teachers, but it also includes teaching and learning processes that were studied in situ.
