1. 6. Rhythm of the job stress blues : Psychosocial working conditions and depression in working life and across retirement

   Författare :Julia Åhlin; Linda Magnusson Hanson; Hugo Westerlund; Tarani Chandola; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; job stress; psychosocial working conditions; job demand-control-support model; effort-reward imbalance model; organizational justice; depressive symptoms; longitudinal studies; trajectory analysis; latent class analysis; fixed-effects regression; folkhälsovetenskap; Public Health Sciences;

   Sammanfattning : A work environment characterized by poor psychosocial working conditions may lead to stress and mental health problems such as depression, a common and burdensome public health problem with significant consequences for individuals and for society at large. A number of psychosocial working characteristics have been found to be associated with increased depressive symptoms or clinical depression. LÄS MER

3. 7. Moisture Induced Stress Perpendicular to Grain in Timber Structures

   Författare :Martin Häglund; Avdelningen för Konstruktionsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood.; timber; perpendicular to grain; load combination factor; tensile stress; mechano-sorption; Moisture induced eigen-stress; varying moisture content;

   Sammanfattning : Timber structures and wooden element are in general affected by moisture and moisture variation in different ways. Their hygroscopic properties result in adsorption of water when wetted and in desorption when dried. LÄS MER

4. 8. Nutrient balance and salinity stress in arbuscular mycorrhizal fungi

   Författare :Edith Hammer; MEMEG; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inoculum; Glomalin; Fatty acids; Osmolyte; Organic matter; K; Na; Salinity; Symbiotic exchange; Phosphorus P; Carbon C; PIXE; Arbuscular mycorrhizal fungi; Rhizobium;

   Sammanfattning : Earth’s primary production depends to a considerable extent on the mycorrhizal symbiosis, since mycorrhizal fungi supply their host plant with important mineral nutrients. I examined the influence of different nutrient regimes on the fungal partner in the arbuscular mycorrhizal symbiosis. LÄS MER

5. 9. Determination of biomarkers for lipid peroxidation and oxidative stress : Development of analytical techniques and methods

   Författare :Kristina Claeson Bohnstedt; Bo Karlberg; Niels Heegaard; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; capillary electrophoresis; mass spectrometry; electrospray; porous graphitic carbon; oxidative stress; lipid peroxidation; biomarker; malondialdehyde; hydroxynonenal; isoprostane; Analytical chemistry; Analytisk kemi;

   Sammanfattning : Oxidative stress can be defined as a state of disturbance in the pro-oxidant/antioxidant balance in favour of the former, leading to potential damage. Processes associated with oxidative stress involve reactive oxygen species and radicals and can result in elevated levels of oxidatively modified or toxic molecules that can cause cellular malfunction, and even cell death.

7. 10. Global-Scale Modelling of the Land-Surface Water Balance : Development and Analysis of WASMOD-M

   Författare :Elin Widén-Nilsson; Sven Halldin; Chong-yu Xu; Lars-Christer Lundin; Jens Christian Refsgaard; Uppsala universitet; []
   Nyckelord :Hydrology; Global; Water balance; Runoff; Regionalisation; Model uncertainty; Multi-objective; Parameter; Evaluation criteria; Routing; Climate change; Hydrologi;

   Sammanfattning : Water is essential for all life on earth. Global population increase and climate change are projected to increase the water stress, which already today is very high in many areas of the world. The differences between the largest and smallest global runoff estimates exceed the highest continental runoff estimates. LÄS MER
