Introduction Tibial osteotomy by the hemicallotasis technique is a clean elective operation. With external fixation pins inserted, close to the knee joint, the infection prophylaxis should be considered. The primary aim was to investigate the differences in the postoperative use of antibiotics during the time in external fixation between administrating prophylactic antibiotics for 3 days or as a s
The relationship between on the one hand personality traits and, on the other hand, neuropsychological test performance, self-rated distress symptoms, psychosocial work exposure, and social interaction patterns, was studied in a group of healthy women (N= 101). All subjects completed the Karolinska Scales of Personality inventory (KSP) and the majority of the subjects (n = 88) completed the State
The effect of shallow water table fluctuations on the evaporation and CO2 fluxes in a peatland is investigated. The fluxes of evaporation and net ecosystem exchange of carbon were measured from mid-spring to the end of summer in 2005 and 2006 and simulated independently with process models. The observed and modelled data were then compared along a gradient of water levels. Any variation along the
Carbon deposition has a serious effect on the performance of solid oxide fuel cells (SOFCs). An unsteady-state 2D model based on COMSOL software is used to study the carbon deposition process in a planar SOFC. The carbon deposition, catalyst activity, reaction rate and temperature fields are obtained to analyse the mechanism of carbon deposition in the SOFC at different operating time. The effects
Popular Abstract in Swedish ”Practice variation” I den kliniska vardagen ser man ofta slående variationer i handläggningsrutiner mellan läkare och vårdcentraler utan att detta kan förklaras av skillnader i sjuklighet hos patienterna. Dessa oförklarade skillnader benämns ”practice variation” och beror på lokalt förankrade rutiner ofta etablerade sedan länge. De är sällan vetenskapligt underbyggda uBackground and Aims: Differences in the clinical care of patients have been explained through the concept of practice variation, that is, the occurrence of established local medical procedures that varies between geographic areas. The primary measures introduced to eliminate undesirable differences in medical care are the introduction of medical guidelines and economical incentives that rewards th
Conjugated polymer/fullerene-based solar cells are, due to their potential flexibility, cost efficiency and low weight, interesting as future alternatives to today’s silicon cells [1]. In these cells, both the dissociation of the polymer exciton into extractable charges, i.e. charges that are free and mobile, and the recombination of the free charges are expected to be crucial in order to obtain h
For a number of applications, gluten protein polymer structures are of the highest importance in determining end-use properties. The present article focuses on gluten protein structures in the wheat grain, genotype- and environment-related changes, protein structures in various applications, and their impact on quality. Protein structures in mature wheat grain or flour are strongly related to end-
We have carried out a combined X-ray photoelectron spectroscopy (XPS), ultraviolet photoelectron spectroscopy(UPS), and scanning tunnelling microscopy (STM) study of the C-60-Si(1 1 1) interaction where the XPS/UPS spectrometer and STM are integrated on a single UHV system. This enables a direct comparison of the XPS/UPS spectra with the STM data and eliminates any uncertainty in C-60 coverage mea
Predator-prey interaction strengths in variable environments constitute a fundamental link to the understanding of aquatic ecosystem responses to environmental change. The present study investigates the effects of visibility conditions and prey fish density on predation rates of visually oriented piscivorous Eurasian perch Perca fluviatilis L. This was done in outdoor mesocosm (16 m(2)) experiment
There is increasing theoretical and empirical evidence that genetic compatibility among partners is an important determinant of fertilization success and offspring viability. In amphibians, females often actively choose partners from among a variety of males and polyandry is common. Genetic compatibility among partners may therefore be an important determinant of fertilization success and offsprin
Objective. We assessed the relationships between (I) ultrasonography calcaneus T-scores (PIXI) and mandibular cortex characteristics on oral panoramic radiographs in older subjects; and (II) osteoporosis and periodontitis. Material and methods. We examined 778 subjects (53% women) aged 59-96 years. Periodontitis was defined by alveolar bone loss assessed from panoramic radiographs. Results. PIXI c
Populations at range limits are often characterized by lower genetic diversity, increased genetic isolation and differentiation relative to populations at the core of geographical ranges. Furthermore, it is increasingly recognized that populations situated at range limits might be the result of human introductions rather than natural dispersal. It is therefore important to document the origin and
Prenatal testosterone surge is considered crucial for physiological masculinization of male progeny. Disorders in sex steroid hormone balance during the fetal development may interfere with male reproductive health later in life. In this study, we have investigated in utero and in vitro effects of flutamide (FLU) and diethylstilbestrol (DES) on fetal rat testicular steroidogenesis. In utero exposu
Due to the recent advances in digital detector technology, there is an increasing trend in the use of digital mammography (DM) as a concurrent modality with screen-film mammography (SFM). In order to fully realize its potential, the components of a DM system should be optimized with respect to clinical image quality in order for clinicians to make accurate diagnoses. The studies in this work invol
We extend the Tasche (2007) model on the asset correlation bias caused by a currency mismatch between assets and liabilities to the more realistic situation where some assets, and some, but not necessarily all, liabilities, are denominated in a foreign currency. To test the significance of the remaining bias we rely on a unique data base constructed by The Inter-American Development Bank (IADB) co
Lichens, a form of symbiosis between a fungal and a photosynthetic partner, are believed to be a group that evolved early in the history of terrestrial life. As a consequence, they probably experienced higher ultraviolet (UV) radiation fluxes than at present. However, in the last two decades, due to the depletion of the stratospheric ozone layer, increasing levels of ultraviolet-B radiation (280-3
