Atmospheric mercury levels around the world's largest mining and refining complex (Almaden, Spain) were determined during two field campaigns (September 1993 and February 1994) using both point monitors and lidar techniques. High mercury concentrations (0.1-5 mu g m(-3)) were measured over the village of Almaden in the prevailing wind direction. In the month of September the total mercury flux int

This paper presents a finite element analysis which is validated against laboratory tests of eight beams strengthened with externally bonded with carbon fibre reinforced plastic (CFRP) plates. The commercial numerical analysis tool Abaqus was used. Cohesive elements were used to model traction and shear behaviour of concrete/CFRP interface. The results are presented and discussed in terms of loadi

Background People applying for a housing adaptation (HA) grant are at great risk of participation restrictions due to declining capacity and environmental barriers. Aim To investigate the association of person-, environment-, and activity-related factors with participation frequency and satisfaction among people applying for a housing adaptation grant. Material and methods Baseline cross-sectional

Quality is an aspect of high importance in software development projects. The software organizations have to ensure that the quality of their developed products is what the customers expect. Thus, the organizations have to verify that the product is functioning as expected and validate that the product is what the customers expect. Empirical studies have shown that in many software development pro

Endotoxaemia is thought to occur in cardiac surgery using extracorporeal circulation (ECC) and a positive correlation has been proposed between the magnitude of endotoxaemia and risk for postoperative complications. We studied the effects of a new endotoxin adsorber device (Alteco(R) LPS adsorber) in patients undergoing cardiac surgery with ECC, with special reference to safety and ease of use. Fi

This study examines to what extent English speakers of L2 Dutch reconstruct the meanings of placement verbs when moving from a general L1 verb of caused motion (put) to two specific caused posture verbs (zetten/leggen ‘set/lay’) in the L2 and whether the existence of low-frequency cognate forms in the L1 (set/lay) alleviates the reconstruction problem. Evidence from speech and gesture indicates th

Does a rising tide lift all boats? This question – that is, to what extent does improvements of the general economy benefit all – is central to the study of economics and history. From fundamental issues about whether market forces have an innate tendency to increase or decrease differences in economic outcomes, to much debated questions about the effects of government policies, distributional con

Context and Objective:Total muscle triglyceride (MT) content has been associated with insulin resistance. We investigated the predictors and impact of MT on relevant metabolic parameters including peripheral and hepatic insulin resistance in elderly twins.Design and Participants:Seventy-four elderly same-sex twins underwent hyperinsulinemic euglycemic clamps preceded by an iv glucose tolerance tes

The aim of this study was to evaluate thermo-thresholds in autologous reconstructed microtic ears. Nineteen patients with unilateral microtia were investigated no less than two years after the last operation (3.6+/-1.7 years). Their normal corresponding ear acted as controls. Eight healthy children were also investigated to illustrate technical differences between measuring the two sides. Thermal
