The theory and practice of suction porosimetry methods (suction plate, pressure membrane and centrifuge) are reviewed together with related methods based on the rate of penetration of wetting liquids, and on static and dynamic fluid/fluid displacement measurements.
A four-element conical electron lens has been developed in view of its integration to a double toroidal electron energy analyzer (DTA) dedicated to Auger electron-ion coincidence measurements. The lens design, using electron trajectory numerical simulations, was entirely guided by the perspective of analyzing energetic electrons with high resolution in the multicoincidence regime. The design, cons
GaMnSb/GaSb(100) layers with embedded MnSb inclusions have been grown at 720 K using MBE technique. This paper presents the investigation of the defect structure of Ga1-xMnxSb layers with different content of manganese (up to x = 0.07). X-ray diffraction method using conventional and synchrotron radiation was applied. Dimensions and shapes of inclusions were detected by scanning electron microscop
Background: The aim of this study was to investigate the association of sex hormone-binding globulin (SHBG) and hypertension in a Swedish population. Methods: The study is based on a random sample of a Swedish population of men and women aged 30-74 years (n=2,816). Total testosterone, oestradiol and SHBG were measured in 2,782 participants. Free androgen index was then calculated according to the
Popular Abstract in Swedish Fältskiktet gör skillnaden! Dynamiken av näringsämnen och organiskt material i bokskogens övre markskikt Frida Andreasson, Växtekologi och systematik, Lunds universitet Det övre markskiktet i bokskogen är markens mest biologiskt aktiva del. Därför är kunskapen om denna del av marken, dess egenskaper och kemi, angelägen. Särskilt viktig är kunskapen om mineraliseringeThe objective of this thesis was to quantify differences between adjacent patches with and without ground flora of Deschampsia flexuosa L. Trin or Anemone nemorosa L. in two acid European beech (Fagus sylvatica L.) forest floors in south-west of Sweden. The studies included soil properties and chemistry, N mineralisation and bioavailability of dissolved organic carbon (DOC), in soil leachates (SL)
Abstract in Italian Questo articolo tratta del ruolo importante che il sistema Ghent ed altre caratteristiche delle relazioni industriali in Svezia rivestono nel mantenimento di alti livelli di densità sindacale in Svezia. Il governo di centro-destra, insediatosi in seguito alle elezioni parlamentari nel settembre 2006, nel 2007 ha introdotto o tentato di introdurre modifiche sostanziali nelle ass
The well-established symmetry relations for linear transport phenomena cannot, in general, be applied in the nonlinear regime. Here we propose a set of symmetry relations with respect to bias voltage and magnetic field for the nonlinear conductance of two-terminal electric conductors. We experimentally confirm these relations using phase-coherent, semiconductor quantum dots.
Twenty years after Vassar College welcomed the first American female undergraduates in 1865, the experiences of women college students began to be fictionalized in so-called college stories. This thesis shows how higher education is presented in the novels, collections of short stories, and serialized stories for female readers published before the United States was involved in the First World Wa
In Sweden "anonymous living donation'' (ALD) has recently been performed but is still under evaluation. We considered it important to learn more about the thoughts of the volunteers for such a donation. Five persons out of ten people who had volunteered to donate anonymously at the transplant unit at Malmo University Hospital were interviewed. The main reason for the wish to donate was the possibi
The genetic basis of complete C4 deficiency in a patient with SLE was investigated. Previous studies have demonstrated that this patient has two different major histocompatibility complex (MHC) haplotypes that each contain a major deletion and a non-expressed C4 gene. In the present study, non-expression of the C4 genes was explained by the finding of two distinct C4 gene mutations. A previously d
Background and Purpose - Warfarin prevents stroke in atrial fibrillation (AF); however, concerns regarding international normalized ratio control and hemorrhage limit its use in the elderly. The oral direct thrombin inhibitors (DTIs) are potential alternatives to warfarin, offering fixed dosing without drug and dietary interactions and the need for international normalized ratio monitoring. Althou
Objective: The insulin responsive adiponutrin (PNPLA3 or ADPN) gene shows association with obesity and in vitro adipocyte lipolysis. This study aimed to replicate the association between PNPLA3 variants and obesity, and to investigate their effect on insulin resistance and beta-cell function. Methods: rs738409 (Met148Ile) and rs2072907 (C to G) were genotyped using TaqMan allelic discrimination as
Platelet-derived growth factor-B (PDGFB) is necessary for normal cardiovascular development, but the relative importance of different cellular sources of PDGFB has not been established. Using Cre-lox techniques, we show here that genetic ablation of Pdgfb in endothelial cells leads to impaired recruitment of pericytes to blood vessels. The endothelium-restricted Pdgfb knockout mutants also develop
OBJECTIVES: The aim of this study was to evaluate the applicability of total plasma protein adducts (TPPA) of 2 sensitizing low-molecular-weight allergens, hexahydrophthalic anhydride (HHPA) and methylhexahydrophthalic anhydride (MHHPA), as biomarkers of long-term exposure. METHODS: Urine samples from occupationally exposed workers were analyzed for the levels of urinary metabolites of HHPA and MH
We studied host selection and exploitation, two crucial aspects of parasite ecology, in Achrysocharoides parasitoid wasps, which show remarkable host specificity and unusual offspring sex allocation. We estimated a molecular phylogeny of 15 Achrysocharoides species and compared this with host (plant and insect) phylogenies. This tri-trophic phylogenetic comparison provides no evidence for cospecia
The scope of this work is a new methodology to correct conventional near-infrared (NIR) data for scattering effects. The technique aims at measuring the absorption coefficient of the samples rather than the total attenuation measured in conventional NIR spectroscopy. The main advantage of this is that the absorption coefficient is independent of the path length of the light inside the sample and t
Background and purpose: The purpose of this work was a comparison of realistic IMRT plans based on the same CT-image data set and a common predefined set of dose objectives for the planning target volume and the organs at risk. This work was part of the larger European QUASIMODO IMRT verification project. Materials and methods: Eleven IMRT. plans were produced by nine different European groups, ea
The surface pressure–molecular area (–A) relationship for spread layers of the high molecular-weight glutenin subunit 1Dx5, a 58 kDa peptide derived from the central repetitive domain of the subunit, and an -gliadin fraction was measured by means of a surface film balance (Langmuir trough). The aqueous phase was a 10 mM acetate buffer, pH 4.0, either with or without 100 mM NaCl. Subunit 1Dx5 gener
