en studie om herbicidresistens; mekanismer, detektion och åtgärder
Herbicide resistance is the result of an evolutionary process where a population gradually changes from being susceptible to being resistant to an herbicide. The resistance mechanism is usually a change in the biochemistry of the weed, but in some cases changes in morphology or …
The aims of the study were to investigate the prevalence and antibiotic resistance of Campylobacter jejuni and Campylobacter coli in chicken and chicken products, and to investigate farmer awareness of antibiotic resistance development. The study was conducted in the Can Tho …

… Vaccines and antimicrobials are used to control the disease. Antimicrobial resistance and the prevalence of several different toxin genes and toxigenic strains make it problematic. The aim of this literature study was to identify potential differences between countries and …
bioassays with the insect herbivores Spodoptera littoralis and Agriotes spp.
… domestication. During human selection to improve the yield of plants, the resistance against herbivore attack can have been lowered, due to a trade-off for use of resources between these traits in the plants. In this thesis I investigated the effect of domestication on …
new knowledge for integrated pest management
… health problems for farmers, contamination of water and soil, insecticide resistance development and decrease in natural enemy populations. The implementation of control measures that do not imply an added burden to the environment and/or the farmers is urgent. More knowledge …
Anthelmintic resistance is a major problem in sheep husbandry all over the world. One way toslow down the development of anthelmintic resistance is to keep part of the parasitepopulation in refugia (unexposed to drugs) which will maintain the genes for susceptibilitywithin the …
… trials and laboratory experiments showed that pollen beetles had developed resistance against pyrethroids. Between 2001 and 2003 several field trials were laid out in Östergötland to investigate pollen beetle mortality from different groups of insecticides. The results shows …
… methods. Two identification methods are presented in this thesis, resistance encoding and 1-Wire. They are investigated and discussed on the basis of a set of predetermined demands such as response time and the amount of unique switches the method can distinguish. The practical …
Background: Chemotherapy and radiation resistance are major causes of failure in cancer treatment. The response to treatment in cancer cells depends on several mechanisms and pathways such as Janus kinases-signal transducers and activators of transcription JAK/STAT pathway …

… processes and institutions. Fundamentalism and terrorism are seen as a violent resistance to repressed subjectivity, but the form of resistance depends on the discursive and non discursive surroundings. This gives rise to different forms of resistance; the production of …
en resurs för att reducera antibiotikaanvändningen
… approximately 60 years. Very few new antibiotics are introduced and increased resistance is a major problem that requires everyone to take responsibility to reduce the use of it. Infections are often treated with antibiotics, which provide a selective pressure on bacteria and …
… an analysis of the project, that is based on theories of power, resistance and contemporaryurban development, it examines the construction of urban space, its impact on public art including the ability of art to initiate evolvement of the urban public space.The last decades art …
En jämförande studie mellan tre manliga detektiver och deras likheter och olikheter
… to discover not one but several different histories as well as signs of resistance. As for research on women, I use the concept of dynamic hierarchies by which should be understood that the combination of variables such as age, sex, socio-economic standing and cultural …
