  2. 1. Monitoring anti-infectives and antibiotic resistance genes : with focus on analytical method development, effects of antibiotics and national perspectives

    Author : Ghazanfar Ali Khan; Jerker Fick; Klaus Kümmerer; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; method development; on-line solid phase extraction liquid chromatography mass spectrometry SPE LC-MS MS ; antibiotics; anti-infectives; constructed wetlands CWs ; denatured gradient gel electrophoresis DGGE ; percentage removal efficiency PRE ; shannon index; antibiotic resistance genes ARGs ; real-time polymerase chain reaction RT-PCR ; drug formulation facilities DFF ; wastewater; epidemiology; pandemic; influenza; compliance;

    Abstract : Antibiotics are biologically active and are globally used in humans and animal medicine for treatment and in sub-therapeutic amounts as growth promoters in animal husbandry, aquaculture and agriculture. After excretion, inappropriate disposal and discharge from drug production facilities they enter into water bodies either as intact drugs, metabolites or transformed products. READ MORE

  5. 3. Integrating food production and biodiversity : energy and scale issues in implementation

    Author : Kristina Belfrage; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The aim of this thesis was to test the hypotheses that (1) biodiversity at a farm level differs between small and large farms, and (2) it is possible to combine high biodiversity at farm level with high food production, sustainable nutrient circulation, and self-sufficiency in fuels. In the research area in SE Sweden, six small farms (135 ha) were selected for the studies. READ MORE

  6. 4. The Ecological Role of Roadside Stormwater Ponds - Potential to Support Biodiversity

    Author : Zhenhua Sun; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Macroinvertebrates; Stormwater ponds; DNA metabarcoding; Sediments; High throughput sequencing; Road runoff; Water quality; Aquatic biodiversity;

    Abstract : The increased recognition that roads may impair the aquatic environment and ecosystems has led to a shift from conventional drainage systems toward blue-green solutions such as stormwater ponds. Research on blue-green stormwater solutions has until now mainly focused on water quantity and quality. READ MORE

  7. 5. Genetic diversity and grain protein composition of tetraploid wheat (Triticum durum Desf) germplasm from Ethiopia

    Author : Faris Hailu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The extent and patterns of genetic diversity in landraces of tetraploid wheat germplasm collected from major wheat-producing regions of Ethiopia were assessed with the use of agromorphological,phenol-qualitative traits, grain proteins and molecular markers. The extent of genetic erosion of landraces in tetraploid wheat germplasm from Ethiopia was also evaluated. READ MORE
