Adsorption onto hydrophobic surfaces of α-, β-, γ-, and ω-gliadins from the wheat variety Chinese Spring was studied by means of in situ ellipsometry. Most measurements were conducted in 0·01m phosphate buffer, pH 6·0, with the protein concentrations 1, 5 and 25 μg/mL. The adsorbed amount varied between 1·3 and 11·4 mg/m2, which is high considering the low protein concentrations. The concentration

The adsorption of β-lactoglobulin onto methylated silica surfaces and the subsequent protein removal by the anionic surfactant sodium dodecyl sulphate (SDS) were followed using in-situ ellipsometry. Experiments were performed at pH 6.0 in phosphate-buffered saline solution. Parameters varied include temperature, length of time for protein adsorption from solution and surface residence time of β-la

In Eli F. Heckscher's conception of the world, what he called “distributary systems” (ledningssystem) played a dangerously crucial role. He used this term to denote the means of transport, communications and power transmission, that is, in substance those activities which are commonly termed natural monopolies. Until the 1920s he believed that these monopolies could be held in check by potential c

Importance: Proposal of an innovative approach to clarify the mechanism through which poor cognitive performance in adolescence impacts risk for schizophrenia (SZ).Objective: To determine whether the developmental processes that predispose to SZ are better reflected by the observed cognitive performance in adolescence or the deviation of that performance from the individual's familial cognitive ap

Purpose – The purpose of this paper is to investigate whether and how knowledge hoarding, functions as antecedent and consequent of work related negative acts, as a measure of bullying. The authors investigate the relation as mediated by trust and justice. Design/methodology/approach – Data stem from a longitudinal study in which questionnaire responses were collected twice from 1,650 employees in

This pictorial review highlights cancers detected only at tomosynthesis screening and screens falsely recalled in the course of breast tomosynthesis screening, illustrating both true-positive (TP) and false-positive (FP) detection attributed to tomosynthesis. Images and descriptive data were used to characterise cases of screen-detection with tomosynthesis, sourced from prospective screening trial

BACKGROUND: High body mass index (BMI) and low physical fitness are risk factors for stroke, but their interactive effects are unknown. Elucidation of interactions between these modifiable risk factors can help inform preventive interventions in susceptible subgroups.METHODS: National cohort study of all 1,547,294 military conscripts in Sweden during 1969-1997 (97-98% of all 18-year-old males). St

In this work, physical and chemical characterization of El- Lajjoun retort water from oil shale pyrolysis process has been carried out. Comparison of different treatment methods for the major components which could affect the design and operation of any set of wastewater treatment process were conducted. The removal of phenol and ammonia using activated carbon after 12 hour resident time were 93 a

The change in the secondary structure of T4 lysozyme upon adsorption to silica particles was studied with circular dichroism. Two different mutants of the protein along with the wild type were investigated. The mutants differ from wild type by substitution of isoleucine for cysteine or tryptophan at position 3 and were chosen to represent a range of stability as quantified by their energies of the

The extensive fouling common in the food industry puts high demands on equipment cleaning. The adsorption of β-lactoglobulin and its removal by the anionic surfactant sodium dodecyl sulphate (SDS) were followed at pH 6.0 using in situ ellipsometry. Hydrophilic chromium oxide and stainless steel together with hydrophobic methylated silica were studied at different temperatures. Differences between

Fifty years have passed since the Stockholm School of economic thought was carried to the font by Bertil Ohlin. As was fitting, the anniversary was celebrated with a conference in Stockholm to which prominent economists made pilgrimage from near and far. Even before this, an extra fine commemorative gift had been proffered in Lund, the very city from which such bitter criticism had once upon a tim
