2. 1. Rectal washout in rectal cancer surgery

   Author : Rebecca Svensson Neufert; Malmö Institutionen för kliniska vetenskaper; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rectal washout; Rectal cancer surgery; Local recurrence; Anterior resection; abdominoperineal resection; Transanal total mesorectal excision;

   Abstract : BackgroundRectal washout (RW) is performed to eliminate intraluminal cancer cells and thereby reducing the risk of local recurrence (LR). The overall aim of this thesis was to investigate the importance of RW in rectal cancer surgery.MethodPaper I: Survey of the current practice of RW among Swedish colorectal units. READ MORE

4. 2. Persistent organic pollutants in the atmosphere - spatial and temporal variations

   Author : Cecilia Backe; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; tropical and temperate regions; global transport; temperature; latitudinal fractionation; fugacity; soil organic matter; soil-air exchange; washout ratio; rain; precipitation; atmosphere; spatial and temporal variations; DDT; PCB; persistent organic pollutants; polychlorinated biphenyls; Environmental chemistry; Miljökemi; Ecology; Ekologi; Chemistry; Kemi;

   Abstract : In these thesis I have studied the spatial and temporal variations of PCBs in the atmosphere and in precipitation in southern Sweden. Further, soil-air exchange processes of PCBs were investigated. Finally, the long-range transport of PCBs and DDT was studied in the Baltic Sea region and in a tropical vs. a temporal region.

5. 3. Polybrominated diphenylethers in the environment - Local and long range transport

   Author : Arnout ter Schure; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Substance Flow Analysis; Spatial Variation; Sources; PCB; PBDE; Latitude; Global Fractionation; Frogs; Deposition; Atmosphere; Baltic Sea; Ekologi; Temperature; Washout ratio; Ecology;

   Abstract : I have studied the sources, long range transport, and rates of flow of polybrominated diphenyl ethers (PBDEs), from the technosphere to the Baltic ecosystems. PBDEs are mainly used in polymers, which are applied in electrical equipment to prevent overheating or flashover and are produced in large quantities. READ MORE

6. 4. Enhanced Methane and Hydrogen production in Reverse Membrane Bioreactors via Syngas Fermentation

   Author : Konstantinos Chandolias; Hariklia N. Gavala; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; syngas fermentation; CH4; H2; cell washout; inhibitors; mass transfer; Resource Recovery; Resursåtervinning;

   Abstract : of waste treatment processes, such as the anaerobic digestion. This biochemical process converts organic substrates into biogas, with anaerobic microorganisms. However, some types of substrates have low bio-degradability due to its recalcitrance or the presence of inhibitors. READ MORE

7. 5. Ethyl glucuronide : a new biochemical marker for acute alcohol intake : studies on possible causes for false-negative or false-positive results

   Author : Helen Dahl; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : In recent years, there has been a growing interest in various biochemical markers for detecting acute and chronic alcohol consumption. Biochemical markers for acute and chronic drinking play important roles in detecting alcohol use, abuse and dependence in hospital settings, work place settings, traffic medicine and in forensic toxicology examinations.
