1. 1. Obsessive-compulsive disorder, serotonin and oxytocin : treatment response and side effects

   Författare :Mats B. Humble; Ingemar Engström; Lars von Knorring; Lars Kjellin; Lil Träskman-Bendz; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adverse effects; Obsessive-compulsive disorder; Orgasm; Oxytocin; Randomised controlled trial; Rating scale; Response prediction; Serotonin; Serotonin uptake inhibitors; Sexual function; Psychiatry; Psykiatri;

   Sammanfattning : Obsessive-compulsive disorder (OCD), with a prevalence of 1-2 %, frequently leads a chronic course. Persons with OCD are often reluctant to seek help and, if they do, their OCD is often missed. This is unfortunate, since active treatment may substantially improve social function and quality of life. LÄS MER

3. 2. Toward Anti-icing and De-icing Surfaces : Effects of Surface Topography and Temperature

   Författare :Golrokh Heydari; Per Claesson; Eric Tyrode; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anti-icing; topography; supercooled water; wetting hysteresis; superhydrophobic; contact angle; nucleation; freezing delay; de-icing; ice adhesion; hydration water; liquid-like layer; smooth; lubrication; anti-is; topografi; underkylt vatten; vätningshysteres; superhydrofob; kontaktvinkel; kärnbildning; avisning; isadhesion; hydrerat vatten; vätskeliknande skikt; smörjning; Kemi; Chemistry;

   Sammanfattning : Icing severely affects society, especially in the Nordic countries. Iceaccumulation can result in critical performance problems and safetyconcerns for instance in road, air and sea transportation, transmissionlines, marine and offshore structures, wind turbines and heat exchangers.

4. 3. Evolutionary consequences of maternal effects and stress

   Författare :Piotr K. Rowiński; Björn Rogell; Karl Gotthard; Katja Räsänen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; parental effects; meta-analysis; development time; bet-hedging; brain size; evolutionary potential; unpredictable environments; zoologisk ekologi; Animal Ecology;

   Sammanfattning : Maternal effects occur when maternal environment or phenotype influence offspring phenotype, in addition to genetic contribution of the mother. As maternal effects often influence phenotypes that are under natural selection, they hence have evolutionary consequences. LÄS MER

5. 4. Characterization and Compensation of Thermal Effects in GaN HEMT Technologies

   Författare :Johan Bremer; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal coupling; thermal effects; thermal resistance; AlGaN GaN; temperature compensation.; electrothermal; characterization;

   Sammanfattning : Further advancements with GaN based technologies relies on the ability to handle the heat flux, which consequently arises from the high power density. Advanced cooling techniques and thermal optimization of the technology are therefore prioritized research areas. LÄS MER

7. 5. Conservation of landlocked Atlantic salmon in a regulated river : Behaviour of migratory spawners and juveniles

   Författare :Anna Hagelin; Eva Bergman; Fleming Ian; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atlantic salmon; conservation; migration; spawning; hydropower; competition; juveniles; brown trout; hatchery reared; fallback; delay; Biology; Biologi;

   Sammanfattning : Hydropower dams represent one of the major threats to river ecosystems today. The dams block migratory routes in many rivers, which is problematic for migratory fish species. Trap-and-transport may be an alternative to fish passage solutions, as a strategy to compensate for lost river connectivity. LÄS MER
