Estimations of past male and female serum concentrations of biomarkers of persistent organochlorine pollutants and their impact on fecundability estimates.

Persistent organochlorine pollutants (POPs) have been suggested to have negative effects on a number of hormonal systems. Several studies performed retrospectively have reported a possible association between POP exposure and fertility, measured as time to pregnancy (TTP). However, these studies lack biomarkers of exposure at the time when the women tried to conceive. It has previously been found

Length of the antibody heavy chain complementarity determining region 3 as a specificity-determining factor

lThe antigen binding site of an antibody is made up of residues residing in six hypervariable loops of the heavy and light chains. In most cases several or all of these loops are required for the establishment of the antigen-binding surface. Five of these loops display a limited diversity in length and sequence while the third complementarity determining region (CDR) of the heavy chain is highly d

Markets for energy efficiency: Exploring the implications of an EU-wide 'Tradable White Certificate' scheme

Recent developments in European energy policy reveal an increasing interest in implementing the so-called ‘Tradable White Certificate’ (TWC) schemes to improve energy efficiency. Based on three evaluation criteria (cost-effectiveness, environmental effectiveness and distributional equity) this paper analyses the implications of implementing a European-wide TWC scheme targeting the household and co

Psychometric properties concerning four instruments measuring job satisfaction, strain, and stress of conscience in a residential care context.

There are many instruments assessing the wellbeing of staff, but far from all have been psychometrically investigated. When evaluating supportive interventions directed toward nurse assistants in residential care, valid and reliable instruments are needed in order to detect possible changes. The aim of the study was to investigate validity in terms of data quality, construct validity, convergent a

Temperamental influences on children's risk-taking in decision making: A dual process, multi-level analysis

Risk-taking can be either adaptive or maladaptive depending on the context, but maladaptive risk-taking sometimes has serious consequences. Understanding how self-control and other aspects of personality are related to risk-taking is important, as self-control can be improved through training. We examined how the regulative temperamental trait Activation control interacts with the reactive traits

Quantifying the release of lactose from polymer matrix tablets with an amperometric biosensor utilizing cellobiose dehydrogenase.

The release of lactose (hydrophilic) from polymer tablets made with hydrophobically modified poly(acrylic acid) (HMPAA) have been studied and compared it to the release of ibuprofen, a hydrophobic active substance. Lactose is one of the most used excipients for tablets, but lactose release has not been widely studied. One reason could be a lack of good analytical tools. A novel biosensor with cell

Search for top squark pair production in final states with one isolated lepton, jets, and missing transverse momentum in root s=8 TeV pp collisions with the ATLAS detector

The results of a search for top squark (stop) pair production in final states with one isolated lepton, jets, and missing transverse momentum are reported. The analysis is performed with proton-proton collision data at root s = 8 TeV collected with the ATLAS detector at the LHC in 2012 corresponding to an integrated luminosity of 20 fb(-1). The lightest supersymmetric particle (LSP) is taken to be

Impacts of climate and emission changes on nitrogen deposition in Europe: a multi-model study

The impact of climate and emissions changes on the deposition of reactive nitrogen (Nr) over Europe was studied using four offline regional chemistry transport models (CTMs) driven by the same global projection of future climate over the period 2000-2050. Anthropogenic emissions for the years 2005 and 2050 were used for simulations of both present and future periods in order to isolate the impact

Selective cefuroxime prophylaxis following colorectal surgery based on intra-operative dipslide culture

The concept of a very limited effective period for prophylactic antibiotic action was challenged in a prospective, controlled and randomized study featuring a simplified method for assessing the degree of contamination in the operative field during colorectal surgery. The 226 patients were given 1 g metronidazole IV on induction of anaesthesia and 12 h postoperatively. Following standardized salin

Full-field ERG and visual fields in patients 5 years after discontinuing vigabatrin therapy.

Purpose In numerous studies vigabatrin medication has been associated with visual field constriction and alterations in the full-field electroretinogram (ff-ERG), but it is not clear whether these changes are reversible or not. The purpose of this study was to examine patients with visual field loss and reduced ff-ERG several years after discontinuing vigabatrin therapy, in order to investigate re

QCD Phenomenology of Heavy Particle Dynamics

Popular Abstract in Swedish Teorin för den starka kraften, kvantkromodynamik eller QCD, behandlas här med både perturbativa och icke-perturbativa metoder. Speciellt produktions- och hadroniseringsdynamiken hos tunga partiklar studeras. Dessa partiklar innefattar tunga kvarkar (charm, botten och top), gaugebosoner, leptokvarkar och supersymmetriska partiklar. När tunga långlivade kvarkar (d.v.s. cIn this thesis the phenomenology of Quantum Chromo Dynamics (QCD) is studied in a variety of circumstances from both perturbative and non-perturbative perspectives. The main emphasis is on the production and hadronization of heavy particles, specifically heavy quarks, gauge bosons, leptoquarks and supersymmetric particles. In the hadroproduction of long-lived heavy quarks (i.e. charm and bottom)

Child Molesters and Children as Witnesses : Spatial Behaviour, Modus Operandi and Memory Recall

Offenders who target children are a negative phenomenon in our society. These offenders are often seen as the worst of the worst of criminals and are therefore a priority for investigators trying to solve these crimes as fast as possible. The purpose of this thesis is to see if there are common denominators among these offenders in their modus operandi (MO) and their spatial patterns. If similar p

A novel triple mix radiobinding assay for the three ZnT8 (ZnT8-RWQ) autoantibody variants in children with newly diagnosed diabetes.

BACKGROUND AND AIMS: Autoantibodies against the zinc transporter 8 (ZnT8A) are common in type 1 diabetes (T1D). ZnT8A analyses are complicated by the fact that there are three variants of the autoantigen at amino acid position 325 representing ZnT8-R (Arginine), ZnT8-W (Tryptophan) and ZnT8-Q (Glutamin). The aims of the study were: 1) to develop an autoantigen triple mix Radio-Binding Assay (RBA)

A Study of Human Perception of Intonation in Domestic Cat Meows

This study examined human listeners’ ability to classify domestic cat vocalisations (meows) recorded in two different contexts; during feeding time (food related meows) and while waiting to visit a veterinarian (vet related meows). A pitch analysis showed a tendency for food related meows to have rising F0 contours, while vet related meows tended to have more falling F0 contours. 30 listeners judg

Evaluation of quantitative (90)Y SPECT based on experimental phantom studies.

In SPECT imaging of pure beta emitters, such as (90)Y, the acquired spectrum is very complex, which increases the demands on the imaging protocol and the reconstruction. In this work, we have evaluated the quantitative accuracy of bremsstrahlung SPECT with focus on the reconstruction algorithm including model-based attenuation, scatter and collimator-detector response (CDR) compensations. The scat

Sperm chromatin structure assay in prediction of in vitro fertilization outcome.

Sperm DNA fragmentation index (DFI) assessed by sperm chromatin structure assay is a valuable tool for prediction of fertility in vivo. Previous studies on DFI as predictor of in vitro fertilization (IVF) outcome, based on relatively small materials, gave contradictory results. The present study examines, in a large cohort, the association between sperm DFI and the outcome of IVF/ICSI procedure. T
