1. 11. Pesticide use in periurban areas : farmers’ and neighbours’ perceptions and attitudes, and agricultural field influences on pests in nearby garden plants

   Författare :Ahmed Nur; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Public concern about pesticide use is very high, although it varies with social, ethical and political factors. In periurban regions, farmers live close to people with other occupations. Thus farming activities such as pesticide spraying may cause tensions. LÄS MER

3. 12. Natural enemies: Functional aspects of local management in agricultural landscapes

   Författare :Helena Hanson; Biodiversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Agricultural intensification; sustainable agriculture; land use; management intensity; landscape scale; ecosystem services; biological control; species trait; pesticides; predatory arthropods; parasitoids; pollen beetles;

   Sammanfattning : Agricultural intensification has raised the global food production but also caused major concerns about environmental and health effects, including contamination by pesticides. Pesticide applications may induce toxicity not only on the target pest species but especially on non-target species. LÄS MER

4. 13. Antibody responses in Plasmodium falciparum malaria and their relation to protection against the disease

   Författare :Ahmed Kamal Bolad; Klavs Berzins; Lars Hviid; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; immunity; parasital immunology; Plasmodium falciparum malaria; antibody mediated invasion growth inhibition; Immunology; Immunologi;

   Sammanfattning : Protective immunity against Plasmodium falciparum may be obtained after repeated exposure to infection. Several studies indicate that immunity against the blood stages of the P. Falciparum infection is mainly antibody mediated. LÄS MER

5. 14. Malaria control measures : impact on malaria and anaemia in holoendemic area of rural coastal Tanzania

   Författare :Zul Premji; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Malaria is a major public health problem in tropical Africa. It is particularly the main killer disease in children below five years and its health impact is most severe in the rural areas. Malarial anaemia is believed to be the main complication in high endemic areas. LÄS MER

7. 15. Biodiversity and biological control : effects of agricultural intensity at the farm and landscape scale

   Författare :Camilla Winqvist; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Agricultural intensity on the local field or farm scale and on the regional landscape scale affects the organisms utilizing the arable landscape, and may affect ecosystem services and functions. This thesis examines how plants, birds, community composition of ground beetles, and biological control of cereal aphids are affected by local agricultural intensity, organic farming and the surrounding landscape in Sweden and across Europe.
