2. 1. Statistical Modelling of Cell Cycle Dynamics Analysis and Interpretation of BrdUrd DNA FCM-Derived Data

   Author : Sara Larsson Lönn; Matematisk statistik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; G2 phase duration; DNA replication; flow cytometry; Natural science; Naturvetenskap; S phase duration; DNA distribution; branching processes; cell cycle kinetics;

   Abstract : It it of great importance to increase the knowledge of various cell cycle kinetic parameters and the objective of this thesis is to use stochastic models to interpret Bromodeoxyuridine (BrdUrd) DNA Flow Cytometry (FCM) derived data in order to estimate such parameters. The cell cycle is the process of growth and division that is essential for an organism to increase in size. READ MORE

   Abstract : The topic of this thesis is the development of devices for telecom applications based on poled optical fibers. The focus is on a specific function, optical switching/modulation. Some of the most important results are summarized below. Optical switching at telecom wavelengths (1. READ MORE

5. 3. Modulation of serous salivary gland function by the sympathetic nervous system : a biochemical and ultrastructural study with special reference to β-adrenoceptor subtypes

   Author : Roger Henriksson; Umeå universitet; []
   Keywords : Rat parotid gland; guinea-pig submandibular gland; ß-adrenoceptor subtypes; sympathetic denervation; sympathetic superstimulation; amylase secretion; cyclic AMP; ultrastructural stereology;

   Abstract : The aim of the present investigation was to study the influence of the sympathetic nervous system and of various adrenoceptor agents on enzyme secretion and morphology in rat parotid and guinea-pig submandibular glands. Biochemical methods were combined with electron microscopical techniques. READ MORE

6. 4. Electron Wave Packet Dynamics on the Attosecond Time Scale

   Author : Kathrin Klünder; Atomfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Photoionization; Single attosecond pulses; Attosecond pulse trains; Electron wave packet; Electron dynamics; Interferometry; Photoemission time delay; Fysicumarkivet A:2012:Klünder; Stark spectroscopy;

   Abstract : One objective of attosecond science is to study electron dynamics in atoms and molecular systems on their natural time scale. This can be done using attosecond light pulses. READ MORE

7. 5. Some effects of maternal anxiety on the fetus and on pregnancy outcome

   Author : Karin Sjöström; gynekologisk och prenatal ultraljudsdiagnostik Obstetrisk; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Labour.; Obstetrics; Gestational length; Fetal heart rate patterns; Fetal movement; Fetal hemodynamics; Worry; Life events; STAI; Pregnancy; Anxiety; gynekologi; Obstetrik; reproduction; gynaecology; andrologi; reproduktion; sexualitet; sexuality; andrology;

   Abstract : The aim of this thesis was to study maternal emotional impact on the fetus and on pregnancy outcome. The thesis comprises five papers, which emanate from a prospective study regarding life situation, the experience of pregnancy, anxiety (Spielberger State-Trait Anxiety),and life events in nulliparous women, conducted in Malmö during 1988-1989.
