With a method relying on measurements of the flow of water vapour from a specimen and measurements of the distribution of the relative humidity in the specimen at steady state conditions, the moisture permeability can be calculated and its dependence on the relative humidity can be determined. The specimens are of dimensions that are used in ordinary buildings.

Two prospective studies of the occurrence and clinical significance of post-transfusion hepatitis non-A, non-B were performed in Malmo, Sweden. In both studies, patients of a broad clinical spectrum were followed up 6 and 12 weeks after transfusion. In a 7 week study from 1983, hepatitis non-A, non-B occurred in 9/173 transfused patients (5.2%) versus 1/203 untransfused controls (0.5%) (p less tha

Background Impaired muscarinic receptor-mediated vasodilation is an important feature of early atherosclerosis. Earlier studies on apolipoprotein E-knockout mice (apoE-KO) mice suggested adverse effects of Chlamydia pneumoniae infection on the endothelial vasomotor responses of aortas to the muscarinic agonist methacholine. Using additional aorta samples the present study investigated the response

Popular AbstractSyftet med avhandlingen är att bidra med ny kunskap till det forskningsområde inom ekonomisk geografi som behandlar problem kopplade till industriell dynamik, rumslig organisering av industriell verksamhet och regional näringspolitik. Genom att studera företags strategier och relationer till andra aktörer i och utanför hemmaregionen bidrar avhandlingen till en ökad förståelse för dThe dissertation aims at making a contribution to the field of industrial organization/dynamics, spatial organization of industries and regional policy. This has been done by paying more attention to the strategies of the firm and to the link between the firms, the industry as well as the region and the implications for regional policy. More specifically, the dissertation makes a contribution to e

The objective was to investigate the adaptation ofthe multi-segmented body movements induced over time byvibratory proprioceptive stimulation of the calf muscles and by galvanic vestibular stimulation. Twelve normal subjects were with eyes open or eyes closed exposed to vibratory stimulation of two different amplitudes and frequencies, or to simultaneously applied galvanic and vibratory stimulatio

The present study deals with detection of intra-atrial wavefronts from atrial activation times in adjacent bipolar electrograms. A statistic of the delays within each wave-front was calculated and served as a basis for quantifying the wavefront consistency as well as the propagation of the electrical activity along the catheter. The database consisted of 19 patients for which five electrograms wer

Excited states in the N=47 nucleus Rh-92 were populated via the fusion evaporation reaction Ni-58(Ca-40,alpha pn)Rh-92 at 180 MeV beam energy. A level scheme reaching up to about 7 MeV and probable spins of (19(+)) and (21(-)) was established and interpreted with the shell model in the (p(1/2), g(9/2)) model space.

A non-variational Galerkin method, completely based on B-spline methods is introduced and applied to calculations of resonance positions and widths in H- and He. The results agree very well with other theories and experiments. Photodetachment in H- and photoionization of He are also considered.

It has been suggested that autochthonous (internally produced) organic carbon and allochthonous (externally produced) organic carbon are utilized by phylogenetically different bacterioplankton. We examined the relationship between the source of organic matter and the structure and function of lake bacterial communities. Differences and seasonal changes in bacterial community composition in two lak

A general model for pressure drop calculations in siphons and riser tubes has been developed. The model takes into account different physical flow phenomena such as inlet pressure drop and pressure drop in the tube. For each phenomenon, we applied theory and established correlations to calculate the separate accelerational, frictional, gravitational, and centrifugal pressure drops. Model results a

While populism and populist politics have been the focus of a wide range of studies in the social sciences, few analyses of populist phenomena have moved beyond the level of simple description. This study has three immediate aims: to critique existing theories of populism, to develop a new, analytical view of populism, and apply this view comparatively to two cases. This new view of populism emer

Uttorkning av betong är ett ämnesområde som under lång tid varit i fokus. Genom åren har många skadefall kunnat kopplas till alltför fuktiga betonggolv. Det är inte betongen som tar skada utan vissa material som placerats i direkt anslutning till betongen. Exempel är kemisk nedbrytning av lim under plastmattor, vilket skapat kemiska emissioner som vandrat ut till inomhusluften, eller som lett till

Chromatofocusing of proteins in a microcolumn format (750 mum i.d.) was evaluated with slurry-packed Mono P anion-exchanger beads (10 pin bead size) as chromatographic matrix. Evaluation was performed with three standard proteins in terms of flow rate, Polybuffer 96-acetic acid, pH 6.0, concentration (eluent buffer strength), and detection limit. A column with the dimension 750 pin i.d. x 50 mm le

OBJECTIVE: Self-rated health (SRH) is increasingly attracting attention as a predictor of morbidity and mortality while its relation to impaired function has been given less momentum. The aim of this study was to assess the relation between SRH and the risk of being awarded a disability pension and premature death. METHODS: Five birth-year cohorts of middle-aged men were invited to a screening pro

This paper presents an experimental validation of a proposed non-linear damping model for shaft torsional vibration studies, compared to the linear viscous damping model. Nine different shaft configurations were used. The deflection of each shaft exhibiting free vibration was measured for a period of one minute and the signal component at the natural frequency of torsion was found. The experiments

Gastric intestinal metaplasia (IM) and gastric cancer are associated with Helicobacter pylori, but the bacterium often is undetectable in these lesions. To unravel this apparent paradox, IM, H. pylori presence, and the expression of H. pylori virulence genes were quantified concurrently using histologic testing, in situ hybridization, and immunohistochemistry. H. pylori was detected inside metapla

High-spin states in the nuclei Ga-63 and Ga-65 were studied following the reaction S-32 + Ca-40 at a reaction energy of 125 MeV and using the GASP gamma -ray spectrometer in combination with the ISIS charged-particle detector system. In addition to low-lying negative-parity states with single-particle character, rotational-like cascades built on the 9/2(+) and 19/2(-) states have been observed in

n diagnosing endometrial carcinoma in women with postmenopausal bleeding analysis of lactate dehydrogenase, LD, isoenzymes in uterine aspirates appeared to have 100 per cent sensitivity and negative predictive value combined with high specificity and positive predictive value. Determination of the LD-profile is suggested as a marker for endometrial carcinoma in women with postmenopausal bleeding.

PURPOSE: To relate changing abdominal aortic aneurysm (AAA) morphology after endovascular grafting to the presence of leakage, collateral perfusion, and other factors. METHODS: Thirty-five patients who underwent successful AAA endovascular grafting were evaluated. Self-expanding Z-stents and Dacron grafts were applied in bifurcated and aortomonoiliac systems. Postoperative diameter changes were ca
