2. 1. Modification of flavonoid content and photosynthesis by ultraviolet-B radiation. Atrazine-tolerant and -sensitive ultivars of Brassica napus

   Author : Louise Olsson; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; recovery; quercetin; photosynthesis; photoinhibition; photoacoustics; leaf anatomy; kaempferol; flavonoid; D1 protein; fluorescence; cold stress; carbon dioxide; atrazine tolerance; Brassica napus; UV-B; Physiological biophysics; Växtfysiologi;

   Abstract : Levels of ultraviolet-B (UV-B, 280-320 nm) radiation reaching the Earth´s surface increase due to stratospheric ozone depletion. In this thesis the effect of enhanced UV-B radiation was studied on the atrazine-tolerant mutant Stallion, susceptible to photoinhibition, and the atrazine-sensitive cultivar Paroll of Brassica napus (oilseed rape).

4. 2. Enzymatic and Immunological Detection Principles for Environmental and Biological Applications

   Author : Elisabeth Burestedt; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; interleukin-8; D-ammino acids; carbon paste; flow immunoassays; Amperometric biosensors; phenols; Analytisk kemi;

   Abstract : The aim of the thesis was to develop new analytical detection principles based on enzymatic and immunological reactions for sensitive, selective, cost-effective and high sample through-put detection devices. The thesis presents the basic elements and reaction paths necessary for the construction and development of enzyme based amperometric biosensors and immunoassays. READ MORE

5. 3. Effects of Natural Organic Matter on Herbicide Adsorption to Activated Carbon

   Author : Åsa Edell; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; natural organic matter; herbicide; adsorption isotherm; preloading; activated carbon; competitive interaction;

   Abstract : The presence of pesticides in the aquatic environment represents a potential threat to water quality and human health. Increasingly stringent drinking water quality directives focus on the need for efficient pesticide removal processes. READ MORE

6. 4. Removal of endocrine-disrupting compounds from wastewater using molecular imprinting

   Author : Mathieu Le Noir; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; molecular imprinting; Endocrine-disrupting compounds; wastewater; macroporous gel; trace contaminants;

   Abstract : Endocrine-disrupting compounds (EDCs) such as hormones and certain pharmaceuticals (i.e. birth control pills, oestrogen replacement products and other steroids) can interfere with the regulatory systems of humans and wildlife. Many of these compounds are excreted by humans and released with sewage. READ MORE

7. 5. Molecularly Imprinted Polymers at the Nanometric Scale: Synthetic Receptors for Chemical Sensors

   Author : Anne-Sophie Belmont; Tillämpad biokemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; biopolymers; Polymer technology; Biokemisk teknik; Biochemical technology; Nanostructures; Synthetic Receptors; Optical Sensors; Molecular Imprinting; Polymer; Polymerteknik;

   Abstract : In this thesis, polymerisation techniques or deposition methods have been developed permitting the creation of thin molecularly imprinted polymer (MIP) films or patterns and their interfacing with transducer surfaces for biosensor applications. The creation of ultra thin films has been achieved using two different techniques, spin-coating and in-situ polymerization of thin films of monomers containing a sacrificial polymeric porogen, and autoassembly of MIP nanoparticles with the aid of an associative linear polymer.
