2. 1. Defence and signalling in Potato-Phytophthora infestans interactions

   Author : Ashfaq Ali; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phytophthora infestans; Plant defence; hypersensitive response; resistance; susceptibility;

   Abstract : Potato is one of the major food crops and its yield is severely affected by late blight disease caused by Phytophthora infestans. P. infestans has the ability to manipulate plant defence signalling by secreting effector molecules causing so called effector triggered susceptibility. READ MORE

4. 2. Midkine - a host defence protein

   Author : Sara Nordin; allergologi och palliativ medicin Lungmedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antimicrobial polypeptides; Midkine; antibacterial; antifungal; innate immunity; epithelial surfaces;

   Abstract : Every day we encounter many potentially harmful microbes in our environment. The epithelial linings constitute an anatomical barrier protecting us and they also produce antimicrobial polypeptides (AMPs) that act as a chemical barrier. These AMPs are small and positively charged, killing a broad range of microbes rapidly. READ MORE

5. 3. Sheltered Society : Civilian Air raid shelters in Sweden — from idea to materiality, 1918-1940 and beyond

   Author : Peter Bennesved; Finn Arne Jørgensen; Christer Nordlund; Thomas Kaiserfeld; Umeå universitet; []
   Keywords : HUMANIORA; HUMANITIES; Air raid shelters; Civil defense; Aerial protection; History of Technology; Multi Level Perspective; Large Technical Systems; Fortifications; Networks; idé- och lärdomshistoria; History Of Sciences and Ideas; History; historia;

   Abstract : In 2002, Sweden finally stopped producing air raid shelters for its population after over sixty years of continuous production since 1938. Judging from the Swedish Civil Contingencies Agency, MSB, the Swedish Air raid shelter registry contain about 65,000 air raid shelters registered as being in use. READ MORE

6. 4. Microclimate at range margins : Consequences for boreal forest understory species

   Author : Caroline Greiser; Kristoffer Hylander; Johan Ehrlén; Eric Meineri; Miska Luoto; Alistair Jump; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microclimate; species distribution; range dynamics; boreal forest; canopy cover; topography; soil moisture; air humidity; bryophytes; lichens; vascular plants; biotic interactions; forest management; biodiversity conservation; ekologi och evolution; Ecology and Evolution;

   Abstract : A warmer climate will shift species distributional range margins poleward, but near-ground microclimates may modify these shifts. Cold-adapted northern species at their rear edge may survive locally in microrefugia with a colder microclimate, and warm-adapted southern species at their leading edge may colonize stepping stone habitats with a warmer microclimate.

7. 5. Isocyanates, Amines and Alkanolamines : Sampling, Chromatography and Detection

   Author : Jakob B. Riddar; Marianne Dalene; Gunnar Skarping; Daniel Karlsson; Håkan Westberg; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Air-sampling; Isocyanates; Aromatic amines; Aliphatic amines; Alkanolamines; Hydrophilic Interaction Liquid Chromatography; Dry Denuder-Filter sampler; Liquid Chromatography–tandem Mass Spectrometry; Polyurethane Foam Extraction; Analytical Chemistry; analytisk kemi;

   Abstract : Isocyanates, aromatic-, aliphatic- and alkanolamines are commonly used in the industry today. Millions of workers in Europe are exposed. The most frequent health symptoms are respiratory and dermal disorder. Due to the health risk most of the compounds in this thesis are regulated by authorities and have occupational exposure limits (OELs). READ MORE
