  1. 1. Heat transfer through a well insulated external wooden frame wall : an investigation of the effects of normal defects in the insulation resulting from incident wind and air flow through the wall

    Författare :Peter Roots; Avdelningen för Byggnadsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building construction; Electrical conduits.; Nogging pieces; Airgaps; Breaks in the insulation; Variations in the insulation; Through wind; Forced convection; Incident wind; Byggnadsteknik;

    Sammanfattning : The heat requirement of a building can turn out to be greater than was calculated at the design stage. The reason for this may be that heat transport though the building envelope is greater than expected. This in turn can be due to the structure not fulfilling the design requirements in respect of windtightness and airtightness. LÄS MER

  3. 3. New opportunities provided by the Swedish electricity meter reform

    Författare :Fredrik Wallin; Erik Dahlquist; Eva Thorin; Peter Roots; David Natusch; Mälardalens högskola; []
    Nyckelord :automatic meter reading AMR ; advanced metering infrastructure AMI ; peak load; consumption patterns; visualize; consumption feed-back; added values; demand-based; tariffs; bottom-up modeling; web-based applications; TECHNOLOGY; TEKNIKVETENSKAP; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : The reduction of the impact of energy consumption is a priority issue and a major challenge that concerns every country in the world. This is a complex task that needs to be tackled from several angles in the search for areas where optimizations and savings can be made. LÄS MER

  4. 4. Aquaporin homologues in Norway spruce (Picea abies)

    Författare :Peter Oliviusson; David I. Dunstan; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Växtfysiologi; växtfysiologi; Plant Physiology;

    Sammanfattning : The recent discovery of aquaporins - proteins that mediate bidirectional passage of water over membranes - provides a molecular basis for the underlying processes in plant water relations. In plants, aquaporins are found in plasma membranes and in vacuolar membranes (tonoplasts) and are suggested to participate in dynamic operations such as cell elongation, osmotic regulation, and long-distance transport.

  5. 5. Survival analytic studies of suicide risk

    Författare :Peter Nordström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Suicide risk; suicide; attempted suicide; mood disorder; serotonin; CSF 5-HIAA; personality; temperament; birth cohort analysis; survival analysisStockholm 1995;

    Sammanfattning : Suicide is a major cause of death in Sweden, as measured by potential years of life lost, and suicidal behavior is a grave public health problem. Suicide risk assessment and prediction in the clinical setting is a task of paramount concern to psychiatric services. LÄS MER
