1. 1. Urban shades of green : Current patterns and future prospects of nature conservation in urban landscapes

   Författare :Sara Borgström; Regina Lindborg; Sara Cousins; Thomas Elmqvist; Christer Nilsson; Stockholms universitet; []
   Nyckelord :urbanisation; nature conservation; urban planning; urban systems; nature reserves; Sweden; NATURAL SCIENCES; NATURVETENSKAP; naturresurshushållning; Natural Resources Management;

   Sammanfattning : Urban nature provides local ecosystem services such as absorption of air pollutants, reduction of noise, and provision of places for recreation, and is therefore crucial to urban sustainable development. Nature conservation in cities is also part of the global effort to halt biodiversity decline. LÄS MER

3. 2. Traffic-related pollutants in urban snow : Concentrations, size fractionation, and release with snowmelt

   Författare :Arya Vijayan; Maria Viklander; Helene Österlund; Göran Blomqvist; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Urban snow; Traffic pollution; Suspended solids; Metals; PAHs; Tire and Road wear Particles T RWPs ; Microplastics MPs ; Size fractionation; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

   Sammanfattning : In urban areas with seasonal snow, traffic-related pollutants such as solid particles, metals, chloride, organic pollutants, and microplastics (MPs) can be temporarily stored in snowbanks along roads and streets. When the snow melts, it releases the accumulated pollutants and the resulting snowmelt with diverse pollutants may partly infiltrate into the ground, or enter storm sewers and eventually be discharged into, and impact on, the receiving waters.

4. 3. Microcirculation in skeletal muscle during hypoperfusion : An experimental study regarding some psysiological and pharmacological factors influencing blood flow and oxygen pressure distributions

   Författare :Urban Gustafsson; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : The vascular bed in skeletal muscle plays an important role in the regulation of the systemic circulation. The present study was undertaken to investigate how capillary blood flow and oxygenation in skeletal muscle are affected by: a) a reduction in the levels of respiratory gases in blood, hypocapnia or hypoxia, and b) the interaction of anesthetics (pentobarbital, propofol, ketamine) during hemorrhage, and c) hypotension induced pharmacologically by adenosine, sodium nitroprusside or acetylcholine.

5. 4. The Doctor, the Task and the Group : Balint Groups as a Means of Developing New Understanding in the Physician-Patient Relationship

   Författare :Dorte Kjeldmand; Inger Holmström; Urban Rosenqvist; Bengt Mattsson; Uppsala universitet; []
   Nyckelord :Health services research; General practice; Balint group; Patient-centredness; Competence; Physician-patient relationship; Continuous professional development; Hälso- och sjukvårdsforskning;

   Sammanfattning : The general practitioner has a central position in the health care system, but demands have increased and there are signs of exhaustion in the corps. Patient-centredness is beneficial for the patients and probably for the outcome of health care. LÄS MER

7. 5. Surface-Controlled Chemical Vapor Deposition of Silicon Carbide

   Författare :Jing-Jia Huang; Henrik Pedersen; Urban Forsberg; Örjan Danielsson; Ulf Jansson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Polycrystalline cubic silicon carbide, 3C-SiC, has long been investigated in the field of hard coating materials. The typical synthesis method for 3C-SiC coatings is thermal chemical vapor deposition (CVD) using either multicomponent precursors, e.g. methyltrichlorosilane, or a combination of single component precursors, e.
