1. 1. Urban microclimate and surface hydrometeorological processes

   Författare :Christer Jansson; Per-Erik Jansson; David Gustafsson; Chen Delian; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CoupModel; ENVI-met; roughness sub-layer; urban heat island; Physical geography; Naturgeografi;

   Sammanfattning : The urban near surface atmosphere is of great concern since it affects the climate to which an increasing amount of people are immediately exposed. This study investigated the microclimate in central Stockholm in terms of the thermal conditions in the 0-2. LÄS MER

3. 2. An Exploration of the Behavioral Inhibition System (BIS), Response Inhibition, and Possible Implications in Sports

   Författare :Lina J. K. Eriksson; Billy Jansson; Örjan Sundin; Carolina Lundqvist; Mittuniversitetet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : Large parts of human behaviors are oriented towards achieving a particular goal. Motivational factors in the form of approach and avoidance motivated behavior and executive functions (EFs) such as inhibition are central for goal-directed behavior. LÄS MER

4. 3. A Longitudinal Study of Diabetes Mellitus : With Special Reference to Incidence and Prevalence, and to Determinants of Macrovascular Complications and Mortality

   Författare :Stefan P.O. Jansson; Dan K.G. Andersson; Kurt Svärdsudd; Mats Eliasson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diabetes mellitus; clinical epidemiology; longitudinal study; prevalence; incidence; mortality; macrovascular complications; pharmacological diabetes treatment; hypertension treatment; screening; Family Medicine; Allmänmedicin;

   Sammanfattning : Objectives. To investigate diabetes prevalence, incidence, mortality trends, the effects of hyperglycaemia and blood pressure, diabetes and hypertension treatment, and the effect of screening detection on total and cardiovascular disease (CVD), myocardial infarction (MI) and stroke incidence.Study population and methods.

5. 4. Holocene dynamics in subarctic peat plateaus of west-central Canada : Vegetation succession, peat accumulation and permafrost history

   Författare :A. Britta K. Sannel; Peter Kuhry; Peter Jansson; Ian Brown; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; peatlands; permafrost; carbon accumulation; fire; subarctic; Holocene; Physical geography; Naturgeografi;

   Sammanfattning : Dynamics in vegetation, permafrost and peat and net carbon accumulation rates throughout the Holocene have been studied in two subarctic peat plateaus of west-central Canada through plant macrofossil analysis, geochemical analyses and AMS radiocarbon dating. Peatland formation at the studied sites began around 6600-5900 cal yr BP as a result of paludification of upland forests. LÄS MER

7. 5. Temporal and spatial dynamics in subarctic peat plateaus and thermokarst lakes

   Författare :A. Britta K. Sannel; Peter Kuhry; Peter Jansson; Ian A. Brown; Serge Payette; Stockholms universitet; []
   Nyckelord :Peatlands; permafrost; subarctic; peat plateau; thermokarst lake; macrofossil analysis; carbon nitrogen ratio; peat accumulation; carbon accumulation; remote sensing; binary encoding; time-series analysis; Physical Geography; naturgeografi;

   Sammanfattning : Permafrost peatlands are widespread at high northern latitudes and are important soil organic carbon reservoirs. A future warming in these areas, as suggested by global climate models, can cause thawing and increased ground subsidence (thermokarst), resulting in changes in surface hydrology and ecosystem functioning.
