Is the fact of parenting couples cohabitation affecting the serum levels of persistent organohalogen pollutants?

Organohalogen compounds constitute one of the important groups of persistent organic pollutants (POPs). Among them, due to their long-term health effects, one should pay attention on organochlorine pesticides, polychlorinated biphenyls (PCBs) and perfluoroalkylated substances (PFASs). This paper is an attempt to answer the question about relation between the fact of cohabitation by couples expecti

From 1D Rods to 3D Networks: A Biohybrid Topological Diversity Investigated by Asymmetrical Flow Field-Flow Fractionation

Biohybrid structures formed by noncovalent interaction between avidin as a bridging unit and biotinylated glycodendrimers based on poly(propyleneimine) (GD-B) have potential for biomedical application. Therefore, an exact knowledge about molar mass, dispersity, size, shape, and molecular structure is required. Asymmetrical flow field-flow fractionation (AF4) was applied to separate pure and assemb

Collagenous colitis in systemic sclerosis: an overlooked and treatable complication.

Collagenous colitis (CC) is an inflammatory bowel condition of unknown etiology. Systemic sclerosis (SSc) has been associated with CC in a few cases, but it is not clear whether CC could be considered an unusual manifestation of SSc or an independent condition. Here we present a case of SSc-associated CC and compare routine histology and immunofluorescence studies for allograft inflammatory factor

The acceptable noise level: The effect of repeated measurements.

Objective: This study explores if increasing number of repetitions might improve the precision of the acceptable noise level (ANL) test. Design: We measured twelve ANL repetitions, i.e. four complete ANL tests (4 × 3 repetitions), at one session using diotic presentation and a non-semantic ANL version. Study sample: Thirty-two normal-hearing adults. Results: Small order and fatigue effects were se

Epitaxial growth and surface studies of the Half Heusler compound NiTiSn (001)

The Half Heuslers are currently an attractive family of compounds for high temperature thermoelectrics research, and recently, there has been renewed interest since some of these compounds are proposed to be topological insulators. NiTiSn belongs to the family of 18 valence electron Half Heuslers that are predicted to be semiconducting, despite being composed entirely of metallic elements. The gro

Supercritical fluid extraction (SFE) for determination of metalworking fluid aerosols

A common methodology for analyzing metalworking fluid (MWF) aerosols in workplace air is based on gravimetry before and after organic solvent extraction of the MWFs from a suitable collection filter: Because MWFs have different chemical and physical properties, various mixtures of organic solvents have been used to extract the MWFs from their collection device. An alternative to organic solvents,

Acute myelomonocytic leukemia with inv(16)(p13q22) complicating Philadelphia chromosome positive chronic myeloid leukemia

The reciprocal translocation (9;22)(q34;q11) is highly characteristic of chronic myeloid leukemia (CML) and the pericentric inversion inv(16)(p13q22) is almost only found in acute nonlymphocytic leukemia of the myelomonocytic subtype (ANLL M4). Only twice before have an inv(16) and a t(9;22) been found in the same cells, and both times the patients seemed to have de novo ANLL M4. We describe the c

Huvudgårdar och herravälden : En studie av småländsk medeltid

This dissertation focuses on the medieval nobility and its manors in the inland of Småland. The problems tackled in the dissertation may be divided into two major complexes. One concerns the emergence and growth of the Småland nobility in a long-term perspective, the second concerns the spatial conditions in which the nobles established their manors in the landscape. An important question concerns

Isolation and characterization of solventogenic, cellulase-free xylanolytic Clostridia from cow rumen

Hemicellulolytic obligate anaerobes capable of converting a range of agricultural substrates and monomeric sugars of hemicellulose to solvents and acids were isolated from cow rumen fluid. The strains were identified as 5 strains of C. beijerinckii (3 different genotypes), 3 strains of C. acetobutylicum (2 different genotypes), 1 strain of C. butyricum and 3 strains of C. bifermentans (2 different

Möten som formar - Interaktionsmönster på förskola mellan pedagoger och de yngsta barnen i ett genusperspektiv

Popular Abstract in Swedish I studier rörande de yngsta barnen saknas ofta genusperspektiv. Ett syfte med studien var därför att undersöka interaktionen mellan barnen (1-3 år gamla) och förskolepersonalen på småbarnsavdelningarna vid tre förskolor i ett genus- och kontextuellt perspektiv. Ett annat syfte var att undersöka pedagogernas föreställningar om barn och genus. Ett tredje syfte var att disIn studies concerning the youngest children, the toddlers, the gender perspective is often missing. One aim of the study was, therefore, to investigate the interaction between children and preschool teachers in day care centres in a gender and a contextual perspective. Another aim was to investigate the inner representations of the preschool teachers concerning children and gender. A third aim was

User-related assessment of a driver assistance system for continuous support - a field trial

A Driver Assistance System for Continuous Support continuously evaluates the status of the host vehicle as well as the surrounding traffic based on information from on-board sensors. When the system detects a hazard, it issues a warning to the driver, depending on the degree of the hazard. The effects of this system on driver behaviour and acceptance were evaluated in a field trial carried out in

Objective To assess the effect of GSK2190915 on the allergen-induced asthmatic responses. Methods Nineteen eligible male subjects with mild asthma were enrolled in and completed this four-centre, double-blind, two-way crossover s

Soft Tissue Knee Injury With Concomitant Osteochondral Fracture Is Associated With Higher Degree of Acute Joint Inflammation.

BACKGROUND:Osteochondral fractures are often seen on magnetic resonance imaging (MRI) of acutely injured knees, but their existence has gained little interest because of a lack of knowledge of their relation to treatment options and outcome. It is not clear whether acute phase synovial fluid (SF) concentrations of cartilage and bone markers and proinflammatory cytokines are different between traum

Increased potassium conductance of brain mitochondria induces resistance to permeability transition by enhancing matrix volume.

Modulation of K+ conductance of the inner mitochondrial membrane has been proposed to mediate preconditioning in ischemia-reperfusion injury. The mechanism is not entirely understood but it has been linked to a decreased activation of mitochondrial permeability transition (mPT). In the present study, K+ channel activity was mimicked by picomolar concentrations of valinomycin. Isolated brain mitoch

Degenerate p-doping of InP nanowires for large area tunnel diodes

We have investigated p-doping of InP nanowires using diethyl zinc. Two-terminal devices showed non-linear source-drain characteristics and p-type gate dependence. Electron beam induced current measurements were employed to determine minority carrier diffusion lengths. We used large-area tunnel diodes to demonstrate degenerate doping, showing peak current densities of up to 0.11 A/cm(2) and room te

Managing context data for diverse operating spaces

Context-aware computing is an exciting paradigm in which applications perceive and react to changing environments in an unattended manner. To enable behavioral adaptation, a context-aware application must dynamically acquire context data from different operating spaces in the real world, such as homes, shops and persons. Motivated by the sheer number and diversity of operating spaces, we propose a

Phase Segregation in Individually Dried Particles Composed of Biopolymers.

Mixing of two biopolymers can results in phase separation due to their thermodynamically incompatibility under certain conditions. This phenomenon was first reported when the solution was allowed to equilibrate, but it has later been observed also as a consequence of drying. The challenges of this study were to observe phase segregation by confocal Raman microscopy and LV-SEM on dried film, indivi

Dopant Engineering of Inter-Subband Linewidth and Lineshape in Multiwell Heterostructures

We show by numerical diagonalization of the electronic Hamiltonian including screened coulombic impurities that the inter-subband absorption lineshape and linewidth in heterostructures can be controlled by a suitable location of the dopants. We also point out that the usual optical conductivity calculations that employ the self-consistent Born approximation often lead to incorrect lineshapes, alth
