    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Filamentous fungi; municipal wastewater; pharmaceutical substances; fungal fluidized bed pelleted bioreactor; nutrients; diclofenac; ketoprofen; Trametes versicolor; Aspergillus luchuensis; Filamentösa svampar; kommunalt avloppsvatten; läkemedelsrester; bioreaktor; näringsämnen; diklofenak; ketoprofen; Trametes versicolor; Aspergillus luchuensis; Mikroskopiskās sēnes; sadzīves notekūdeņi; farmaceitiskās vielas; mikroskopisko sēņu bioreaktors; diklofenaks; ketoprofens; Trametes versicolor; Aspergillus luchuensis; Bioteknologi; Biotechnology;

    Sammanfattning : The ever-increasing concern about the widespread occurrence of pharmaceutical substances in the aquatic environment has been recognized as an emerging environmental issue as it can cause undesirable effects on the ecosystem and human health. The current wastewater treatment methods are not designed to treat municipal wastewater from the contamination of various pharmaceutical substances. LÄS MER

  3. 17. Influence of water conditions on growth and mineral nutrient uptake of native plants on clacareous soil

    Författare :Aparna Misra; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; agricultural hydrology; Lantbrukshydrologi; marklära; Växtekologi; Plant ecology; wet growing; wet dry cycles; soil solution; soil moisture; pH; nutrient poor soil; mineral nutrients; dry growing; Bicarbonate; calicole; Soil Science;

    Sammanfattning : The studies presented in Papers I to IV illustrate the importance of soil moisture in soil solution chemistry and response of native plants to the changes induced by change in moisture regime. With the help of glasshouse experiments I tried to study the influence of different treatments of soil moisture conditions on the mineral uptake by native plants of calcareous soil. LÄS MER

  4. 18. Diet and gut microbiota in cardiometabolic health: Studies from the Danish Diet, Cancer and Health – Next Generations Cohort and the sub-cohort MAX

    Författare :Agnetha Rostgaard-Hansen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiometabolic diseases; reproducibility; nutrients; gut microbiota; food frequency questionnaire; risk factors; 24-hour dietary recall; epidemiology; temporal variation; dietary patterns; cohort study; validity;

    Sammanfattning : Cardiometabolic diseases (CMD) are the leading cause of death globally. Diet is a key preventive factor of CMD and a determinant of gut microbiota. Gut microbiota, diet and their interactions have been associated with CMD. In observational studies, diet is measured by self-reported instruments, that need to be validated before use. LÄS MER

  5. 19. From green to yellow : a leaf story

    Författare :Olivier Keech; Per Gardeström; Pierre Dizengremel; Lee Sweetlove; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; chloroplasts; cytoskeleton; darkness; metabolism; microscopy; mitochondria; microtubules; senescence; system redox; Plant physiology; Växtfysiologi;

    Sammanfattning : När ett blad gulnar genomgår det både morfologiska och metaboliska förändringar. Denna process benämns senescence och en förbättrad förståelse av dess mekanismer är viktiga både ur ett grundvetenskapligt perspektiv och för potentiella bioteknologiska applikationer. LÄS MER

  7. 20. Remote sensing of grassland communities : integrated effects of soil nutrients and habitat age

    Författare :Oskar Löfgren; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Remote sensing; Plant ecology; semi-natural grassland; Nitrogen; Phosphorus; Semi-natural grassland; Plant ecology; Remote sensing; Nitrogen; Phosphorus; Spectral reflectance; grassland specialists; Succession;

    Sammanfattning : Semi-natural grasslands are characterized by high fine-scale plant species richness. The richest grassland communities, with many habitat-specialist species, are found in ancient grassland sites that have a long continuity of grazing management and low levels of soil nutrients. Grazed grasslands were widespread in the historical landscape. LÄS MER
