    Sammanfattning : The main purpose of this thesis is to study and analyze how concepts of childhood and adolescence were constructed in scientific medicine during the period 1870 to 1930. The focus in the first part of the thesis is to study the sick girl as a stereotype in 1870–1900. LÄS MER

  3. 2. Iron nutrition dynamics - Differences between calcicole and calcifuge plants

    Författare :Angelika Zohlen; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 10-phenanthroline; 1; chlorophyll; plaque; root; leaf; immobilization; plants; calcifuge; Iron; calcicole; Plant ecology; Växtekologi;

    Sammanfattning : One third of the earth´s soils is calcareous. Calcifuge plants are excluded from these soils, and one of the main causes is Fe deficiency, as Fe solubility in calcareous soil is very low. A lack of Fe lowers chlorophyll content, visible as yellowing of leaves, called chlorosis. LÄS MER

  4. 3. Multiple Aphid resistance from alien sources and its chromosomal location in bread wheat

    Författare :Leonardo Crespo; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []

    Sammanfattning : Wheat (Triticum aestivum) is a very important cereal crop and is cultivated worldwide on more than 200 million hectares annually, with an average grain yield of about 3 t/ha. A number of diseases and pests are known to affect wheat production, with aphids being important insect pests. LÄS MER

  5. 4. Barley defense genes against aphids

    Författare :Aleksandra Losvik; Lisbeth Jonsson; Ulla Rasmussen; Robert Glinwood; Bogumił Leszczyński; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Aphid resistance; protease inhibitor; lipoxygenase; induced plant resistance; volatiles; Hordeum vulgare; Rhopalosiphum padi; Myzus persicae; Plant Physiology; växtfysiologi;

    Sammanfattning : Aphids are insect pests with major importance worldwide. By feeding from plant phloem, they directly withdraw nutrients. The feeding injury is often visible in the form of leaf rolling, chlorosis, necrosis or plant deformation. Their pest status is attributed also to vectoring of plant viruses. LÄS MER

  7. 5. Characterisation of the Clp Proteins in Arabidopsis thaliana

    Författare :Bo Zheng; Adrian K. Clarke; Vaughan Hurry; Cecilia Sundby-Emanuelsson; Umeå universitet; []

    Sammanfattning : Unlike in the greenhouse, plants need to cope with many environmental stresses under natural conditions. Among these conditions are drought, waterlogging, excessive or too little light, high or low temperatures, UV irradiation, high soil salinity, and nutrient deficiency. LÄS MER
