  1. 1. Solar Type Stars as Calibrators : A Photometric and Spectroscopic Study on the Atmospheric Properties of Late-type Stars

    Author : Anna Önehag; Ulrike Heiter; Andreas Korn; Bengt Gustafsson; Frank Grundahl; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; stars: atmospheres; stars: late-type; techniques: photometric; stars: abundances; techniques: spectroscopic; Astronomy; Astronomi;

    Abstract : Detailed knowledge of solar-type stars is essential in the understanding of the evolutionary past, presence and future of the Sun as well as the formation of its planetary system. Moreover, solar-type stars are of key significance for the study of the evolution of the Galaxy. The ages of solar-type stars map the full galactic evolution. READ MORE

  2. 2. Genital human papillomaviruses. Studies of their occurrence, type spectrum and expression

    Author : Ola Forslund; Malmö Klinisk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mRNA expression; microwell; HPV 70; type determination; CIN; quantification; urine; multifocal infections; hybridization; PCR; HPV; human papillomavirus; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : The occurrence of genital human papillomavirus infection was determined in different categories of patients by means of PCR. In high proportion of young women attending an adolescent clinic, the presence of HPV DNA was demonstrated in simultaneously urethral and cervical samples, suggesting that genital HPV infections are often multifocal.

  3. 3. Beta cell function in autoimmune diabetes in young adults

    Author : Carina Törn; Celiaki och diabetes; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ketoacidosis; insulin treatment; prognostic factors; C-peptide; type 2; type 1; IA-2A; ICA; GADA; IAA; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi;

    Abstract : This thesis presents the results from a study of the first four years of diabetes in 879 patients aged 15-34 years at diagnosis. The aims of this study were to compare clinical classification with the presence of autoantibodies, to study the natural course of beta cell function during the first years of disease and to define predictive factors for the remaining beta cell function after diagnosis.

  4. 4. Studies on some pyrochlore type solid electrolytes

    Author : Jekabs Grins; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This article summarizes ionic conductivity studies on a number of compounds crystallizing in the pyrochlore type structure. The pyrochlore structure is described, and the determination of ionic conductivities by means of impedance measurements is discussed. READ MORE

  5. 5. Hot-wall MOCVD for advanced GaN HEMT structures and improved p-type doping

    Author : Alexis Papamichail; Vanya Darakchieva; Anelia Kakanakova-Gueorguieva; Jr-Tai Chen; Zlatko Sitar; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hot-wall MOCVD; III-nitrides; p-type GaN; HEMTs; Linearity; High-Al barrier;

    Abstract : The transition to energy efficient smart grid and wireless communication with improved capacity require the development and optimization of next generation semiconductor technologies and electronic device components. Indium nitride (InN), gallium nitride (GaN) and aluminum nitride (AlN) compounds and their alloys are direct bandgap semiconductors with bandgap energies ranging from 0. READ MORE
