   Sammanfattning : Approximately 75 percent (300 000 km) of the total Swedish road network and 20 percent(20 000 km) of the national road network consists of gravel roads. One of the most significantproblems associated with gravel roads is traffic-generated dust emission, which contributes tothe deterioration of the road surface and acts as a major source of particulate matter releasedinto the atmosphere, thereby involving public economics, road safety, human health, andenvironmental quality.

3. 2. Evaluation of Dust Suppressants for Gravel Roads: Methods Development and Efficiency Studies

   Författare :Karin Oscarsson; Högskolan Dalarna; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gravel road; dust; particulate matter; PM10; horizontal dust diffusion; deteriorations; maintenance; dust control; dust suppressants; efficiency; application rate; leaching; residual concentration; seasonal variations; salt solution; solid salt; calcium chloride; magnesium chloride; lignosulphonate; polysaccharide sugar ; bitumen emulsion; rape oil; starch; surfactant; mesa; clay; fine material content.; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

   Sammanfattning : Application of the proper dust suppressant to a gravel road ensures road safety and riding comfort as well as creating a cleaner and healthier environment for residents in buildings adjacent to the road. It also reduces the need and cost for vehicle repair, road maintenance activities, and aggregate supplementation. LÄS MER

   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Although Cerebral Palsy (CP) is a lifelong disability, the research has mainly focused in children with CP. However, in recent years new studies have examined the different aspects of being an adult with a congenital disability. LÄS MER

5. 4. High-intensity interval training in combination with aerobic or resistance training for patients with breast cancer : a HIIT to counteract detrimental effects of chemotherapy

   Författare :Sara Mijwel; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : With the increasing number of individuals that enter cancer survivorship there is a growing need for interventions that can alleviate treatment-related adverse effects such as fatigue, and that can improve and restore physical functioning and health-related quality of life during and after treatment. After a breast cancer diagnosis, patients with breast cancer show significantly reduced physical activity levels, especially during the adjuvant treatment phase. LÄS MER
