   Sammanfattning : The energy system is being transitioned to increase sustainability. This transition has been accelerated by the increased awareness about the adverse effects of the greenhouse gas (GHG) emissions into the atmosphere. The transition includes switching to electricity as the energy carrier in some sectors, e.g. LÄS MER

   Sammanfattning : During the last decade the transition towards electric propelled vehicles has had an upswing and electric vehicle (EV) sales has increased steadily. This is much due to legislations on lowering emissions but also due to lower total cost of ownership. LÄS MER

5. 29. Muscle function and physical activity in pre-pubertal school children

   Författare :Susanna Stenevi Lundgren; Ortopedi - klinisk och molekylär osteoporosforskning; []

   Sammanfattning : Background: Regular participation in physical activity or organized exercise is regarded as one important lifestyle factor that could improve musculoskeletal health, fitness and body composition. For children and adolescents physical activity is important not only in training of the neuromuscular system, coordination and balance, but in a wider perspective, for adopting a lifestyle that possibly reduces the risk of coronary artery disease, obesity, osteoporosis and other contributors to morbidity and mortality in the population.

   Sammanfattning : With the increasing trends in trade of goods and services as well as the expansion of road infrastructure and networks, commercial road transport has dominated a significant share of inland and urban logistics in the world and particularly in Europe. This includes not only the basic supply of citizens’ needs through long-haul traffic and short-distance city trucks but also by providing urban services such as courier delivery, household waste  pickup and refuse collection as well as passengers movements by public bus transport and inter-city coach transit.
