The long-term advance in the timing of bird spring migration in the Northern Hemisphere is associated with global climate change. The extent to which changes in bird phenology reflect responses to weather conditions in the wintering or breeding areas, or during migration, however, remains to be elucidated. We analyse the relationships between the timing of spring migration of 9 species of trans-Sa
Background: Scale comparative properties of "JCQ-Iike" questionnaires with respect to the JCQ have been little known. Purpose: Assessing validity and reliability of two methods for generating comparable scale scores between the Job Content Questionnaire (JCQ) and JCQ-like questionnaires in sub-populations of the large Job Stress, Absenteeism and Coronary Heart Disease European Cooperative (JACE) s
BACKGROUND. The clinical value of detecting prostate specific antigen (PSA) mRNA in the peripheral blood mononuclear cell fraction of patients (pts) by standard RT-PCR assays with localized prostate cancer remains controversial. We used a quantitative RT-PCR assay to measure the PSA mRNA copy number in addition to the qualitative PSA RT-PCR and correlated the results with clinical parameters. METH
The formation of amylose-lipid complexes of form I (amorphous structure) and form II (crystalline structure) during heating was studied by differential scanning calorimetry (DSC) for a range of monoglycerides and for monoglyceride mixtures. The temperature treatment applied to amylose-monoglyceride-mixtures were either the first scan in DSC (10 °C/min, 15-144 °C) or a prolonged heat treatment wher
The most serious risk connected with transplantations besides infection is graft rejection. Organ transplant recipients (OTRs) perceive graft rejection as a stress factor and a threat. The primary aim of the present study was to examine types of coping used to handle the threat of the risk of graft rejection among OTRs and to investigate relations between coping and perceived threat as well as Hea
Sarcomas are relatively rare malignancies and include a large number of histological subgroups. Based on morphology alone, the differential diagnoses of sarcoma subtypes can be challenging, but the identification of specific fusion genes aids correct diagnostication. The presence of individual fusion products are routinely investigated in Pathology labs. However, the methods used are time-consumin
An evacuation experiment was performed in a road tunnel in order to investigate how motorists behave and emotionally respond when exposed to a fire emergency, how information and wayfinding systems are perceived and whether green flashing lights can influence exit choice. The participants believed that they were taking part in a study about driving behaviour. Approximately I kill inside the tunnel
To investigate if the Swedish entry rules for pets to prevent the introduction of Echinococcus multilocularis (EM) are proportional (i.e. that their costs do not exceed the value of their benefits), a dichotomous-choice contingent valuation study was conducted. The study was performed before the first case of EM was detected in Sweden in February 2011. About 5000, randomly selected, Swedish citize
Many decisions in the everyday work of the structural engineer are taken under the influence of uncertainties. The degree of uncertainty affects the quality and variability of the outcome of the structural design work. The effect of uncertainties related to knowledge and experience of the structural engineer was studied in a round robin investigation. Despite a relatively well defined task, the re
Seven aliphatic dicarboxylic acids (C3-C9) along with phthalic acid, pinic acid and pinonic acid were determined in 35 aerosol (PM10) samples collected over the year at Vavihill sampling station in south of Sweden. Mixture of dichloromethane and methanol (ratio 1:3) was preferred over water for extraction of samples and extraction was assisted by ultrasonic agitation. Analytes were derivatized usi
In this work, the influence of substrate bias voltage on the microhardness, adhesive strength, friction coefficient, and wear rate of AIP Cr2O3 films deposited on AISI 304 stainless steel substrates was investigated systematically. In the meantime, the wear failure mechanism of AIP Cr2O3 films in dry sliding contact was also analyzed and discussed. The results showed that the mechanical properties
Context: The diagnosis of and reporting parameters for prostate cancer (PCa) have evolved over time, yet they remain key components in predicting clinical outcomes. Objective: Update pathology reporting standards for PCa. Evidence acquisition: A thorough literature review was performed for articles discussing PCa handling, grading, staging, and reporting published as of September 15, 2011. Electro
The general purpose was to study pragmatically related abilities in children with early-onset brain damage, i.e. children with cerebral palsy (CP) and children with spina bifida and hydrocephalus (SBH), and in a group of children with pragmatic language impairment (PLI). In study I and III children with CP, SBH and PLI were compared. In study I pragmatically related abilities were assessed. No s
This study analyzed predictors of psychiatric hospitalization in ex-prisoners with substance use problems (N = 4,081) assessed with the Addiction Severity Index and followed post-release for hospitalizations with psychiatric diagnoses (including suicide attempts). Thirty-four percent were hospitalized, and in Cox regression, several substance-related variables predicted hospitalization, including
The incidence of asthma and allergy has increased throughout the developed world over the past decades. During the same period of time, the use of industrial chemicals such as phthalates, commonly used as plasticizers in polyvinylchloride (PVC) flooring material, has increased. The aim of this study was to investigate whether PVC flooring in the home of children in the age of 1-5years is associate
This paper concerns thermometric and direct and indirect investigations of the heat produced by the thermogenic dragon lily (Dracunculus vulgaris) and its main pollinating beetle Protaetia (formerly named Potosia) cretica. The experiments were performed on scented and scentless populations at Panormo, Therisos and Lassithi on the North coast of Crete in the springs of 2007 and 2008. D. vulgaris in
The aim of this study was to investigate how the biomass of extramatrical mycorrhizal mycelia (EMM) is influenced by the addition of different phosphorus (P), potassium (K) and PK fertilizers in peatland forests with variable P and K availability. Four fertilizers were used: apatite, biotite, Rauta-PK (TM) (apatite and ferrosulphate) and a test fertilizer (50% apatite and 50% recycled iron phospha
The objective of this study was to test if apatite amendment stimulates growth of ectomycorrhizal (EM) fungi and if this is influenced by the phosphorus status of the forest. The production of EM mycelia was estimated in four Norway spruce forests in south-western Sweden by incubating sand-filled mesh bags (with or without apatite amendment) in the soil for 8 or 20 months. Fungal biomass in the me
Background: Many patients with aggressive B-cell lymphomas and high clinical risk score still die of lymphoma after conventional R-CHOP chemoimmunotherapy. We hypothesized that intensified chemoimmunotherapy including systemic central nervous system (CNS) prophylaxis improves outcome and reduces the incidence of CNS-related events. Patients and methods: Inclusion criteria were age 18-65 years, pri
BACKGROUND: Knee rotation plays an important part in knee kinematics during weight-bearing activities. An external device for measuring knee rotation (the Rottometer) has previously been evaluated for validity by simultaneous measurements of skeletal movements with Roentgen Stereometric Analysis (RSA). The aim of this study was to investigate the reliability of the device. METHOD: The within-day
