A pilot study has been conducted to find out if and how the building process influences the indoor air or the perception of the indoor air. As the first part of this investigation, a media study of what are considered to be healthy and unhealthy buildings was performed. From this media study two buildings were chosen and their building processes were examined more closely. This was carried out as
Previous research has found that moving objects bias heading perception only when they occlude the focus of expansion (FOE) in the background optic flow, with the direction of bias depending on whether the moving object was approached or at a fixed distance from the moving observer. However, the effect of object motion on heading perception was confounded with object position in previous studies.
Genetic and epigenetic factors may predispose women to polycystic ovary syndrome (PCOS), a common heritable disorder of unclear etiology. Here we investigated differences in genome-wide gene expression and DNA methylation in adipose tissue from 64 women with PCOS and 30 controls. In total, 1720 unique genes were differentially expressed (Q < 0.05). Six out of twenty selected genes with largest exp
The dioxygen we breathe is formed by light-induced oxidation of water in photosystem II. O2 formation takes place at a catalytic manganese cluster within milliseconds after the photosystem II reaction centre is excited by three single-turnover flashes. Here we present combined X-ray emission spectra and diffraction data of 2-flash (2F) and 3-flash (3F) photosystem II samples, and of a transient 3F
A pCb plasmid encoding a beta-lactamase from Haemophilus ducreyi was transferred to Escherichia coli, purified, and characterized. The beta-lactamase could be isolated from a culture filtrate and further purified by ammonium sulfate and chelating Sepharose fast flow loaded with Zn(2+). The purified enzyme resulted in a major band at approximately 30-kDa on SDS-PAGE and its pI was determined to be
The purpose of this work is the investigation of some constitutive and configurational aspects of phenomenological model formulations for a class of materials with history-dependent gradient microstructure. The assumption that the behavior of a material point is affected by history-dependent processes in a finite neighbor of this point yields an extended continuum characterized by non-simple mater
Succession theory focuses on the position of species along the shade tolerance gradient and their ability to colonize recently disturbed patches and has for decades overlooked resprouting as a key trait in community patterns. We study how different species traits interact with disturbance frequency to change species dominance in the canopy, focusing on the effects of resprouting ability. We develo
We report on the performance of a grazing incidence spherical grating monochromator installed at MAX I and designed to cover the photon energy range from about 15-200 eV with high resolving power. It is intended mainly for angle-resolved photoemission work. Therefore, both refocusing optics, to obtain a small spot size at the sample, and a higher order light suppressor, to reduce the content of hi
PURPOSE: To describe a concept for prevention of secondary conditions in individuals with chronic neuromuscular disabilities by using two Swedish developed follow-up-programmes for cerebral palsy (CP; CPUP) and myelomeningocele (MMC; MMCUP) respectively as examples.METHOD: This paper describes and outlines the rationale, development and implementation of CPUP and MMCUP.RESULTS: Both programmes are
This paper adds to the relatively few European studies on the pedestrian friendliness of urban areas, and on transport walking. Using the Human Environment Interaction (HEI) model (Küller, 1991), the study explores the associations between perceived neighbourhood spatialphysical and social environment qualities and walking to neighbourhood destinations, and examines whether these associations are
Sustainability professionals are agents for change towards sustainable development. Such professionals require knowledge from a variety of disciplines, but also competencies to accomplish real-word change. This article evaluates an innovative course, Strategic Environmental Development, which immerses students in a real-life solution-oriented consultancy project in order to develop critical sustai
Defects in ribosome biogenesis and function are present in a growing list of human syndromes associated with cancer susceptibility. One example is X-linked dyskeratosis congenita (X-DC) in which the DKC1 gene, encoding for an enzyme that modifies ribosomal RNA, is found to be mutated. How ribosome dysfunction leads to cancer remains poorly understood. A critical cellular response that counteracts
Crystalline Cs2KMnF6, when prepared below 500°C, adopts a tetragonal elpasolite structure type. Differential scanning calorimetric investigations indicated that Cs2KMnF6 undergoes a phase transition from the low-temperature tetragonal phase (LT) to a high-temperature phase (HT) at about 530°C. Single crystals of the new HT phase could be obtained by annealing a crystalline LT specimen at 600°C fol
A structural phase transition and the equation of state of the simple-hexagonal (sh) phase, P-V, of phosphorus were investigated at pressures up to 280 GPa using monochromatic synchrotron x-ray diffraction. The P-V phase, which was stable above 137 GPa, has shown a structural transition to a higher-pressure phase, P-VI, above 262 GPa, while the c/a ratio of the sh phase slightly increased with inc
In this paper, we present a photoemission study of the interaction of Cu, Ag and Au with clean single-crystal Bi2CaSr2Cu2O8 superconductor surfaces. Both the valence-band and the Bi 5d, O 1s and Sr 3d core levels were monitored for all overlayers. Cu, Ag and Au were deposited as consecutively thicker layers starting with a third of a monolayer and progressing in steps up to a deposition in the ran
Objective-To examine if unilateral knee injury affects the synovial fluid concentrations of aggrecan fragments, cartilage oligomeric matrix protein (COMP) fragments, stromelysin-l, and tissue inhibitor of metalloproteinases-l (TIMP-1) in the contralateral uninjured knee. Methods-Synovial fluids from the injured and uninjured knees were obtained at different times in a group of patients after unila
