2. 16. Investigations of the corrosion resistances of magnetron sputtered multicomponent materials : A study on high entropy alloys, high entropy sublattice ceramics, and metallic glasses

   Author : Aishwarya Srinath; Leif Nyholm; Ulf Jansson; Rebecka Lindblad; Bernard Normand; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Corrosion resistance; high entropy alloys; magnetron sputtering; thin films; protective coatings;

   Abstract : The corrosion resistances of sputter deposited AlCrNbYZrN, CrNbTiTaWC and TaNiSiC alloys were assessed in acidic and alkaline environments. Compositionally complex alloying strategies, and whether they produced coatings with superior corrosion resistances, were explored. READ MORE

4. 17. Protective factors in childhood allergy related to diet and lifestyle

   Author : Helen Rosenlund; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Allergy; antibiotics; antipyretics; asthma; biodynamic; diet; eczema; fruits; measles infection; measles vaccination; multivitamins; rhinitis; sensitization; vegetables;

   Abstract : The prevalence of allergic disease among children has increased markedly during several decades. The reasons behind the increase remain unclear, but lifestyle and environmental factors associated with the Western way of living seem to be of importance. READ MORE

5. 18. Snus use and mortality : associations, potential mechanisms, and socioeconomic aspects

   Author : Marja Lisa Byhamre; Patrik Wennberg; Marie Eriksson; Jan-Håkan Jansson; Magnus Lundbäck; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; snus; Swedish snuff; smokeless tobacco; mortality; cardiovascular; cancer; risk factor; metabolic syndrome; C-reactive protein; vitamin D; testosterone; family medicine; allmänmedicin; befolkningsstudier; Population studies; epidemiologi; Epidemiology; invärtesmedicin; Internal Medicine; Medicine; medicin;

   Abstract : Snus is a smokeless tobacco product made of a moist powder of ground tobacco. It is used mainly in the Nordic countries, although increasingly popular internationally. The Swedish snus tradition dates back to the seventeenth century, and it is now used daily by about 23% of the male and 6% of the female population. READ MORE

6. 19. Whole Genome Sequencing of Enterotoxigenic Escherichia coli

   Author : Astrid von Mentzer; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ETEC; whole genome sequencing; evolution; colonization factor; reverse genetics;

   Abstract : Enterotoxigenic Escherichia coli (ETEC) infections are a common cause of diarrhea but little is known about the evolution and genomic composition of ETEC. The main aim of this thesis was to generate a large collection of whole genome sequenced ETEC isolates to study the evolution of such bacteria on a global level and to search for novel colonization factors (CFs) using both classical and cutting-edge genomic techniques.

7. 20. Homocysteine in cardiovascular disease with special reference to longitudinal changes

   Author : Johan Hultdin; Torbjörn Nilsson; Bertil Kågedal; Umeå universitet; []
   Keywords : Medical sciences; homocysteine; methylenetetrahydrofolate reductase MTHFR ; first-ever stroke; first-ever myocardial infarction; longitudinal; prospective; risk factor; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Chemistry; klinisk kemi;

   Abstract : Abnormalities in homocysteine metabolism have been suggested as risk factors for stroke and myocardial infarction. In retrospective studies, elevated levels of total plasma homocysteine (tHcy) and/or methylenetetrahydrofolate reductase (MTHFR) 677C>T polymorphism have indicated an increase in risk. READ MORE
