2. 1. Methylisothiazolinones. Diagnosis and prevention of allergic contact dermatitis

   Author : Birgitta Gruvberger; Malmö Institutionen för kliniska vetenskaper; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; venereology; Dermatologi; Dermatology; Prevention.; Chemical burns; Occupational dermatoses; Allergic contact dermatitis; Guinea pig maximization test; Isolation identification of contact sensitizers; Inactivation; Methylisothiazolinones; Kathon® CG; venereologi;

   Abstract : Preservatives are biologically active substances which are required in water-based products/systems to prevent growth of micro-organisms. Kathon® CG (K-CG), one of several preservatives based on 5-chloro-2-methyl-4-isothiazolinon-3-one (MCI) and 2-methyl-4-isothiazolin-3-one (MI) has been shown to be a common sensitizer in dermatitis patients.

   Abstract : In this thesis, bio-nanocomposites made from two alternative biopolymers and montmorillonite (Mnt) clay have been investigated by molecular modelling. These biopolymers are xyloglucan (XG) and chitosan (CHS), both of which are abundant, renewable, and cost-effective. READ MORE

5. 3. Water resistance of Scots pine joints produced by linear friction welding

   Author : Mojgan Vaziri; Lars-Olof Nilsson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood; wood welding; crack; CT scanning; image processing; MRI; microdensitometry; CPMAS C NMR; density; water absorption; tensile-shear strength; Träteknik; Wood Technology;

   Abstract : Wood welding is a mechanical friction process allowing the assembly of timber without any adhesives. The process consists of applying mechanical friction, under pressure, alternately to the two wood surfaces to be welded. READ MORE

6. 4. Problems in Number Theory related to Mathematical Physics

   Author : Rikard Olofsson; Pär Kurlberg; Nalini Anantharaman; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; number theory; mathetical physics; local zeta functions; cat maps; Beurling primes; MATHEMATICS; MATEMATIK;

   Abstract : This thesis consists of an introduction and four papers. All four papers are devoted to problems in Number Theory. In Paper I, a special class of local ζ-functions is studied. The main theorem states that the functions have all zeros on the line Re(s)=1/2. READ MORE

7. 5. Environmental Toxins and Essential Trace Elements at Delivery and ADHD

   Author : Amanda Ode; Avdelningen för arbets- och miljömedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PFCs; manganese; selenium; phthalates; ADHD; fetus;

   Abstract : Perfluorinated compounds (PFCs), phthalates, manganese and selenium are ubiquitous in the environment and humans and influence fetal growth and development. Register and biobank based case-control studies were conducted to investigate the relationship between prenatal exposure to these chemicals and attention deficit hyperactivity disorder (ADHD) in childhood.
