BACKGROUND: The transition to studying at university is associated with increased levels of both stress and hazardous alcohol use. The aim of this study is to investigate the influence of these factors on first-year dropout from university studies. METHODS: Two complete cohorts of university freshmen at two homogeneous universities, one in the north and one in the south of Sweden, were asked to pa
Abstract Background. Dosimetry in radionuclide therapy estimates delivered absorbed doses to tumours and ensures that absorbed dose levels to normal organs are below tolerance levels. One procedure is to determine time-activity curves in volumes-of-interests from which the absorbed dose is estimated using SPECT with appropriate corrections for attenuation, scatter and collimator response. From cor
Simmons' lower bound on impersonation P1⩾2 -I(M;E) where M and E denote the message and the encoding rule, respectively, is strengthened by maximizing over the source statistics and by allowing dependence between the message and the encoding rule. The authors show that a refinement of their argument, which removes the assumption of independence between E and the source state S, leads to an
During the influenza pandemic 2009-2010, an AS03- adjuvanted A(H1N1)pdm09 vaccine was used extensively in children 6 months of age and older, and during the 2010-2011 influenza season, the A(H1N1)pdm09 strain was included in the seasonal trivalent inactivated influenza vaccine (TIV) without adjuvant. We evaluated the immunogenicity and safety of TIV in children previously vaccinated with the AS03-
This paper identifies an overdetermination problem faced by the non-reductive dispositional property account of disposition ascriptions. Two possible responses to the problem are evaluated and both are shown to have serious drawbacks. Finally it is noted that the traditional conditional analysis of disposition ascriptions escapes the original difficulty.
Popular Abstract in English This thesis concerns experiments of heat transfer in a rectangular channel with ribs and an obstacle. Liquid crystal thermography (LCT) is used to record the temperature fields in the experiments. LCT is based on measurement of the color response of a heated surface. When illuminated with a white light, the liquid crystals react to temperature changes by changing color,This thesis presents experimental investigations of local heat transfer in a rectangular channel (aspect ratio AR = 4) with continuous transverse ribs as well as an obstacle. Liquid crystal thermography (LCT) is employed to obtain the temperature fields in the heat transfer experiments. The liquid crystal applied here has a red start at 35°C and a bandwidth of 1°C. The work consists of (1) periodi
We report on the general intellectual capacity of men around 17-19 years of age and with cleft lip either with or without cleft palate (CLP) or cleft palate alone. Data were obtained from the Swedish National Service enrolment register for the years 1991-1997, about 335 individuals with CLP and 88 with cleft palate alone, who were compared with a control group consisting of 272 879 people. Those w
A model based on the electrostatic Hellmann-Feynman theorem and an empirical valence-force potential has been used to study breathing-mode distortions around the vacancy and substitutional Cu in silicon. The calculation of the forces driving the distortion is based on a self-consistent calculation of the charge-density perturbation. In both cases considered, the author finds an outward breathing-m
