The aim of the present study was to examine autonomic function in response to negatively and positively valenced pictures under different levels of conscious recognition. Heart period variability (HPV) and heart rate (HR) reactivity were studied in 53 males and females who were being shown pictures of angry and happy faces. The pictures, which were backwardly masked, were presented once every 30 s
The main features of the ultraviolet spectrum of acrolein have been studied by a multireference perturbative treatment and by a time dependent density functional approach. The valence and Rydberg transition energies have been calculated and the assignment of the experimental bands has been clarified. The different relaxation trends of the three lowest singlet and triplet excited states have been a
1. We analysed time-series data from populations of red kangaroos (Macropus rufus, Desmarest) inhabiting four areas in the pastoral zone of South Australia. We formulated a set of a priori models to disentangle the relative effects of the covariates: rainfall, harvesting, intraspecific competition, and domestic herbivores, on kangaroo population-growth rate. 2. The statistical framework allowed fo
During drying, timber distortion is a major defect mainly due to shrinkage anisotropy, differences in longitudinal shrinkage, and spiral grain. The distortion can be reduced by external restraint and use of appropriate kiln schedules. The research presented here is part of a project on the improvement of shape stability of Norway spruce by high-temperature drying. The effects of drying temperature
Today, environmental issues play an important role in the viability of modern low-emission power plants. As a consequence, gas turbine combustors need to be operated at lean premixed conditions. However, successful designs require a detailed knowledge of the combustion process under realistic operating conditions. The present study focuses on nonreacting and reacting jets at operating pressures fr
The interaction between cytoskeletal filaments (e.g., actin filaments) and molecular motors (e.g., myosin) is the basis for many aspects of cell motility and organization of the cell interior. In the in vitro motility assay (IVMA), cytoskeletal filaments are observed while being propelled by molecular motors adsorbed to artificial surfaces (e.g., in studies of motor function). Here we integrate id
The surface structure and chemical composition of annealed Ga0.96Mn0.04As(1 0 0) have been studied by scanning tunneling microscopy (STM), auger electron spectroscopy (AES) and low energy electron diffraction (LEED). The samples were As capped and subsequently transferred in-air from the MBE system to the STM chamber. After annealing to 600 K it is found that the Mn segregates to the surface and f
We have previously proposed the use of Doppler ultrasound to non-invasively stage sinus infection, as we showed that acoustic streaming could be generated in nonpurulent sinus secretions and helped to distinguish it from mucopurulent sinus secretions. In order to continue this development of a clinically applicable Doppler equipment, we need to determine different dimensions of the paranasal sinus
This work concerns experimental and numerical studies of pressure drop and heat transfer for turbulent flow inside a U-duct and in particular the bend part. Such duct geometries can be found in many engineering applications where cooling air extracts heat from hot internal walls of the duct, e.g., passage cooling inside gas turbine blades. The details of the duct geometry were as follows: the cros
Popular Abstract in Swedish Ämnet för avhandlingen är verbets morfologiska och stilistiska variation i den grekiska versromanen Erotokritos, ett av de främsta exemplen på den kretensiska renässansdiktningen. Undersökningen utgår från de i dikten förekommande verbformernas morfologiska variation, både vad avser stammar, ändelser och augment. Undersökningen koncentreras på de imperfektiva verbformerThe aim of the present study is to examine the polytypia (morphological variation) and semantic differentiations of the verb in Vitsentzos Kornaros' Erotokritos, to understand how these shape poetic style. We examine the stems and the endings in the imperfective active forms. Moreover, we investigate the augmented forms because at an early stage we found that Kornaros employs a degree of poetic li
Background - Patient-reported assessments of freezing of gait (FOG) in Parkinson's disease (PD), such as the FOG questionnaire (FOGQ), are needed because FOG is difficult to assess objectively. However, the measurement properties of the FOGQ have been sparsely assessed. Aim - To assess the measurement properties of the Swedish FOGQ, and to explore relationships between FOGQ scores and other aspect
In the recently introduced high-contrast transmission version of saturated absorption laser spectroscopy, narrow signals are obtained from dense atomic samples subject to strong pumping. A study of possible systematic shifts of the signals in this domain of rather extreme experimental conditions was performed in order to assess the validity of spectroscopic data obtained with this technique. Certa
Background and Objective: Several investigations indicated that laser Doppler flowmetry on the liver surface reflects relative changes of the total liver blood flow. In this study, Laser Doppler Perfusion Imaging (LDI), monitoring the surface only, was used for measurements of tissue perfusion of normal and/or impaired liver, pancreas, spleen, stomach and intestine, and the blood flow of hepatic t
ABSTRACT: Study Design. Prospective randomized controlled study.Objective. To compare the outcome of indirect decompression by means of the X-Stop implant to conventional decompression in patients with neurogenic intermittent claudication due to lumbar spinal stenosis.Summary of Background Data. Decompression is the golden standard for lumbar spinal stenosis nowadays but afflicted with complicatio

In the literature, there are several different suggestions as to when the first postoperative pin-site care should be carried out to best prevent pin-site infections during the treatment by external fixation. In a cohort study, we compared the use of antibiotics and complications in patients where the theatre dressing was changed during the first postoperative week with patients where the theatre
