1. 6. Health and Social Determinants Among Boys and Girls in Sweden : Focusing on Parental Background

   Författare :Heidi Carlerby; Katja Gillander Gådin; Anders Knutsson; Eija Viitasara; Ina Borup; Mittuniversitetet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bullying involvement; discrimination; foreign extraction; gender; WHO-HBSC; intersectional perspective; health risk behaviour; parental background; PSP; SHC; SCOS; socio-demography; mobbning; diskrimination; utländsk härkomst; genus; WHO-HBSC; intersektionalitetsperspektiv; hälsoriskbeteende; föräldrabakgrund; PSP; SHC; SCOS; sociodemografi;

   Sammanfattning : The majority of Swedish boys and girls have good psychosomatic health. Despite that the risk of mental health problems such as nervousness, feeling low and sleeping difficulties has increased steadily in recent decades. LÄS MER

3. 7. The relationship between social support, personality and depression in the general population : Focusing on older people

   Författare :Siv Grav; Ove Hellzen; Eystein Stordal; Mittuniversitetet; []
   Nyckelord :Depression; home nursing care; older people; personality; Depresjon; eldre; hjemmesykepleie; personlighet; sosial;

   Sammanfattning : Today's wide variety of diseases and health problems areinfluenced in part by an aging population and by environmental andlifestyle changes. Depression is one of the most quickly growingdisorders, causing a huge decrease in quality of life. Depression alsoincreases with age. LÄS MER

4. 8. Electrophoretic focusing in microchannels combined with mass spectrometry : Applications on amyloid beta peptides

   Författare :Saara Mikkonen; Åsa Emmer; Johan Jacksén; Tapio Kotiaho; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; amyloid beta; computer simulation; electrophoresis; electrospray ionization; isoelectric focusing; isotachophoresis; MALDI; mass spectrometry; microchannel; microchip; nano-electrospray ionization; preconcentration; separation; Kemi; Chemistry;

   Sammanfattning : Analysis of low-abundance components in small samples remains a challenge within bioanalytical chemistry, and new techniques for sample pretreatments followed by sensitive and informative detection are required. In this thesis, procedures for preconcentration and separation of proteins and peptides in open microchannels fabricated on silicon microchips are presented. LÄS MER

5. 9. Focusing properties of attosecond pulses

   Författare :Maria Hoflund; Atomfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The discovery of high-order harmonic generation (HHG) has made it possible to see the electron dynamics on their natural time scale, attoseconds. In the HHG process, a femtosecond infrared (IR) laser pulse is converted into a train of attosecond pulses in the extreme ultraviolet (XUV), but with a very low conversion efficiency. LÄS MER

7. 10. Experimental and numerical investigations of hydrodynamic focusing of colloidal dispersions

   Författare :V. Krishne Gowda; Fredrik Lundell; Daniel Söderberg; Lynn Walker; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microfluidics; flow focusing; colloidal fiber dispersion; effective interfacial tension; microflow morphology; nanoparticle orientation; Mikrofluidik; flödesfokusering; kolloidala dispersioner; effektiv ytspänning; mikroflödesmorfologi; orientering av nanopartiklar; Teknisk mekanik; Engineering Mechanics;

   Sammanfattning : Dispersed non-spherical particles are the fundamental constituent of many complex fluids. Such fluids are studied both for their industrial and scientific importance, and for their peculiar functional properties (mechanical, optical, thermal, fluidic). LÄS MER
