    Nyckelord :EFA; perinatal period; lactation; diet; adipose tissue; leptin; programming;

    Sammanfattning : Nutritional factors during a sensitive perinatal period may lead to developmental adaptations proposed to program for pathological conditions later in life. An adequate supply of essential fatty acids (EFA) during pregnancy and lactation is crucial for optimal fetal and postnatal development. LÄS MER

    Sammanfattning : Background: Ambulatory Care Sensitive Conditions (ACSC) are health conditions for which adequate management, treatment and interventions delivered in outpatient setting could avoid the need of hospital admission. Hospitalizations for ACSC have been used to assess access, quality, and performance of the Primary Health Care (PHC). LÄS MER

  4. 3. Tree Rings as Sensitive Proxies of Past Climate Change

    Författare :Håkan Grudd; Wibjörn Karlén; Brian Luckman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tree ring; width; density; climate; temperature; change; variability; sensitivity; Torneträsk; Tornetrask; Sweden; Fennoscandia; explosive; volcanic; eruption; Santorini; Thera; subfossil; Fitzroya; Chile; Physical geography; Naturgeografi;

    Sammanfattning : In the boreal forests of the Northern Hemisphere, time series of tree-ring width (TRW) and maximum density in the latewood (MXD) are highly correlated to local instrumental summer-temperature data and are thus widely used as proxies in high-resolution climate reconstructions. Hence, much of our present knowledge about climatic variability in the last millennium is based on tree-rings. LÄS MER
