2. 1. Our Bones, who art contaminated : Glues, strontium isotopes, and mobility in early Swedish Christians

   Author : Crista Adelle Wathen; Kerstin Lidén; Sven Isaksson; Christophe Snoeck; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; Strontium isotopes; contamination; conservation; glues; Christianity; mobility; early Christians; Sweden; Varnhem; Västerhus; bones; teeth; Scientific Archaeology; arkeologi med inriktning mot laborativ arkeologi;

   Abstract : This thesis aims to build upon previous research into contamination and its effects on isotopes by focusing on the strontium isotopic ratio (87Sr/86Sr), which is used in mobility studies to study the movements of past humans and animals and to build past economic trading networks. Contamination is a broad topic, and in the scope of this thesis, it concerns the introduction of contaminants from the soil after interment and the post-excavation preservation efforts. READ MORE

4. 2. A study of wood adhesion and interactions using DMTA

   Author : Anna Backman Sandlund; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Physics; Träfysik;

   Abstract : The aim of the work presented in this thesis was to investigate whether the adhesion of glues and lacquers to wood could be studied using dynamic mechanical thermal analysis (DMTA). This method has been widely used to study interactions in polymer blends, copolymers and in polymeric composites but very few investigations had been done on solid wood. READ MORE

5. 3. Organic solvents and cognitive functioning. With special reference to interaction with aging

   Author : Linda Nordling Nilson; Göteborgs universitet; []
   Keywords : Solvents; occupational; neuropsychology; cognition; aging; chronic toxic encephalopathy; follow-up studies;

   Abstract : The aim of the thesis was to study cognitive functioning in patients with chronic toxic encephalopathy (CTE) and in aging workers previously exposed to organic solvents. The discriminative power of a series of cognitive tests in identifying patients with CTE was examined. READ MORE

6. 4. Biomarkers of aromatic isocyanates in exposed workers

   Author : Pernilla Lind; Avdelningen för arbets- och miljömedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adducts; biomarkers; exposure; occupational; methylenediphenyl diisocyanate; toluene diisocyanate; amines; isocyanates; polyurethane; Gas chromatography; mass spectrometry; Occupational health; industrial medicine; Yrkesmedicin; arbetsmiljömedicin;

   Abstract : The aromatic isocyanates, toluene diisocyanate (TDI) and methylenediphenyl diisocyanate (MDI), are used in the production of polyurethane (PUR) foams, paints, elastomers and glues. The use of isocyanates is increasing, and exposure to isocyanates is the most common cause of occupational asthma. READ MORE

7. 5. Isocyanates - assessment of human exposure

   Author : Håkan Tinnerberg; Avdelningen för arbets- och miljömedicin; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pollution control; Miljöteknik; kontroll av utsläpp; Analytical chemistry; Analytisk kemi; exposure; biomonitoring; occupational; isophorone diisocyanate; hexamethylene diisocyanate; methylenediphenyl diisocyanate; toluene diisocyanate; amines; aminoisocyanates; polyurethane; isocyanates; Liquid chromatography; Environmental technology; mass spectrometry;

   Abstract : Isocyanates are used mainly for manufacturing of polyurethane (PUR) foams, lacquers, elastomers and glues. The production of PUR exceeds 2 million tonnes per year and is increasing. Occupational exposure to isocyanates are associated with respiratory disorders. READ MORE
