BACKGROUND: Municipal drinking water contaminated with perfluorinated alkyl acids had been distributed to one-third of households in Ronneby, Sweden. The source was firefighting foam used in a nearby airfield since the mid-1980s. Clean water was provided from 16 December 2013.OBJECTIVE: To determine the rates of decline in serum perfluorohexane sulfonate (PFHxS), perfluorooctane sulfonate (PFOS) a

The purpose of this project was to assess the effects of oral contraceptives (OC) on exercise capacity in female elite soccer players. Fourteen subjects (N=7 oral contraceptives users (OCU) + 7 non-OCU (N-OCU)) were recruited. An assessment of body composition was determined by Dual energy X ray absorptiometry and endogenous ovarian hormone concentrations in serum measured. A maximal treadmill tes

The aim of this paper is to examine and conceptualize how the integration of smartphones is reconfiguring the retailscapes of stores and the implications that this has for retailers and consumers. Departing from an understandingof retailscapes as socio-material assemblages and drawing on an ethnographic study of mobile shopping, this paper shows how the integration of smartphones into the activiti

This study explores how a platform approach facilitates the implementation of advanced service offerings in manufacturing firms. Understanding servitization through a platform approach is important because many manufacturing firms fail to manage the service paradox, that is, the challenge of simultaneously enriching the value proposition by adding services while maintaining cost levels. This study

Aerosol loss in air intake systems potentially hampers the application of one-filter systems for progeny-based atmospheric 222radon (222Rn) measurements. The artefacts are significant when air has to be collected via long sampling lines, e.g. from elevated heights at tall tower observatories. Here we present results from a study, determining 222Rn progeny loss from ambient air sampled via 8.2 mm i

Examination of the interethnic tensions in the Republic of Macedonia and the political dynamics they set in motion

The formation of new atmospheric particles involves an initial step forming stable clusters less than a nanometre in size (~10 nm). Although at times, the same species can be responsible for both processes, it is thought that more generally each step comprises differing chemical contributors. Here, we present a novel analysis of measurements from a unique multi-station ground-based observing syste

Intrinsic water-use efficiency (iWUE) characterizes the physiological control on the simultaneous exchange of water and carbon dioxide in terrestrial ecosystems. Knowledge of iWUE is commonly gained from leaf-level gas exchange measurements, which are inevitably restricted in their spatial and temporal coverage. Flux measurements based on the eddy covariance (EC) technique can overcome these limit

This report contains the student papers describing the projects in the 2017 course Projects in Automatic Control (FRTN40). The course is given annually by the Department of Automatic Control, Lund University, during the second half of the fall semester, with the possibility of projects starting at other times upon agreement. It is an advanced level course, giving 7.5 ECTS credits. The main purpose

Uniform arrays of submicron hexagonal InGaN pyramids with high morphological and material homogeneity, reaching an indium composition of 20%, are presented in this work. The pyramids were grown by selective area metal-organic vapor phase epitaxy and nucleated from small openings in a SiN mask. The growth selectivity was accurately controlled with diffusion lengths of the gallium and indium species
