1. 1. Survival after different forms of bystander cardiopulmonary resuscitation in out-of-hospital cardiac arrest : ‛to breathe or not to breathe?’

   Författare :Gabriel Riva; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Out-of-hospital cardiac arrest (OHCA) affects more than 6000 people per year in Sweden and only one in ten survive. One of the most important modifiable factors determining survival is early cardiopulmonary resuscitation (CPR), but different forms of CPR and their association with survival remain inadequately studied.

3. 2. A methodology to simulate automotive disc brake tribology and emissions

   Författare :Gabriele Riva; Jens Wahlström; Tore Vernersson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Design; Maskinkonstruktion;

   Sammanfattning : Airborne particle emissions from road vehicles are one of the main issues affecting urban air quality. Vehicle disc brakes are one of the most important sources of non-exhaust emissions, which have recently been considered to be as important as exhaust emissions. LÄS MER

4. 3. Psychobiological responses in women with regional or widespread musculoskeletal pain conditions

   Författare :Roberto Riva; Petra Lindfors; Steven J. Linton; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; fibromyalgia; shoulder and neck pain; salivary cortisol; urinary catecholamines; cardiovascular responses; Psychology; psykologi;

   Sammanfattning : Musculoskeletal disorders (MSDs) are very common. Regional chronic shoulder and neck pain (SNP) and widespread chronic pain due to fibromyalgia syndrome (FMS) are examples of MSDs characterized by altered physiology of the autonomic nervous system (ANS) and the hypothalamic-pituitary-adrenal (HPA) axis.

5. 4. Lipase-Catalyzed Syntheses of Telechelic Polyesters

   Författare :Magnus Eriksson; Karl Hult; Mats Martinelle; Sergio Riva; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Candida antarctica lipase B; lipase-catalysis; polymerization; telechelic; functional polyesters; ring-opening polymerization; polycondensation.; Biochemistry; Biokemi;

   Sammanfattning : Telechelic polyesters have successfully been synthesized with lipase-catalyzed polymerization. The produced telechelics had a high degree of di­functionalization, high purity (requiring little or no workup) and controlled degree of polymerization. The syntheses were performed in one-pot one-step reaction systems. LÄS MER

7. 5. Building blocks for polymer synthesis by enzymatic catalysis

   Författare :Stefan Semlitsch; Mats Martinelle; Sergio Riva; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Enzyme; Enzyme Engineering; Biocatalysis; Lipase; CalB; MsAcT; Substrate specificity; Selectivity; Polymer Chemistry; Polymer Synthesis; Bioteknologi; Biotechnology;

   Sammanfattning : The search for alternatives to oil-based monomers has sparked interest for scientists to focus on the use of renewable resources for energy production, for the synthesis of polymeric materials and in other areas. With the use of renewable resources, scientists face new challenges to first isolate interesting molecules and then to process them. LÄS MER
