Med hjälp av ett automatiserat mätsystem för partikelhalter i vatten har vattenkvaliteten vid Borensbergs vattenverk i Motala kommun undersökts under ett års tid med avseende på mikroskopiska partiklar i dricksvatten och råvatten. Antalet mikroskopiska partiklar registrerades som absoluta värden i realtid. I denna artikel diskuteras hur larmgränser skall definieras i praktiken för partikelhalter oDuring a one year long research project at Borensberg Waterworks, Motala, Sweden, water quality with respect to microscopic particle counts both in raw water and drinking water have been monitored by an online water quality monitoring system. Microscopic particle counts were documented with absolute values in real-time. In this paper, a discussion is introduced on how to analyze large data sets fr

Extensive analyses of known monogenic causes of stroke by whole-exome/genome sequencing are technically possible today. We here aimed to compile a comprehensive panel of genes associated with monogenic causes of stroke for use in clinical and research situations. We systematically searched the publically available database Online Mendelian Inheritance in Man, and validated the entries against orig

Buildings are responsible for a third of global greenhouse gas emissions, with much of their life cycle impacts stemming from embodied impacts of building materials. Both at EU and Member State level, circular economy and resource efficiency policies are promoting production of lower-impact building materials with secondary material input. However, secondary material strategies do not result in ca

By aiming to establish single-ended standoff combustion diagnostics, bidirectional lasing emissions of atomic hydrogen at 656 nm wavelength have been generated via two-photon resonant excitation by focusing 205 nm femtosecond laser pulses into a premixed CH4/O2 flame. The forward lasing strength is approximately one order of magnitude stronger than that of the backward one, due to the geometry of

Bilingual children are at a disadvantage when compared to monolingual norms in language assessment. Monolingual assessment fails to acknowledge the asymmetrically distributed linguistic competence of bilingual children, for example, different levels of mastery of family and school related concepts in the first and second languages, respectively. Consequently, monolingual assessment results in an o

The current work aims at investigating the detailed spatial structure of the thin plasma column of a gliding arc (GA) discharge extended in N2-CH4 gas mixtures, using visualization techniques. The GA discharge was operated at up to 5 atm in a high-pressure vessel with extensive optical access. The results show that the emission intensity from the plasma column increased tenfold with the addition o

AIM: We assessed whether baseline measurements of physical activity, aerobic fitness, body fat and abdominal fat were predictors of changes in body fat measurements over a two-year period.METHODS: The study comprised of 204 children aged 9.8 ± 0.6 years with a normal body mass distribution, who recruited from four schools in middle-class areas of Malmö, Sweden, from 2001 to 2004. Peak oxygen uptak

A laser-based technique for recording absolute air-fuel ratio maps in a single-laser pulse in combustion devices, for instance, prior to ignition in internal combustion engines, is demonstrated. The method is based on an in situ pulse-to-pulse calibration of two-dimensional laser-induced fluorescence (LIF) images of relative fuel distributions by a point Raman measurement. A single excimer laser p

Nanowire geometries are leading contenders for future low-power transistor design. In this study, low-frequency noise is measured and evaluated in highly scaled III-V nanowire metal-oxide-semiconductor field-effect transistors (MOSFETs) and in planar III-V MOSFETs to investigate to what extent the device geometry affects the noise performance. Number fluctuations are identified as the dominant noi

Background: Borderline ovarian tumors (BOTs) are a subgroup of ovarian malignancies with low malignant potential. Very limited earlier data are available on familial clustering of BOTs with other cancers. We aim to explore histology-specific familial associations among BOTs and associations between BOTs and any invasive cancers.Methods: On the basis of 16.1 million individuals in the Swedish Famil

Objective To study whether male childlessness is associated with an increased risk of metabolic disorders such as metabolic syndrome (MetS) and diabetes. Design A population-based cohort study. Setting Not applicable. Participants 2572 men from the population-based Malmö Diet and Cancer Cardiovascular Cohort. Interventions None. Main outcome measures From cross-sectional analyses, main outcome mea

Background: Nerve growth factor (NGF) and brain-derived neural factor (BDNF) are important for brain function and detectable in the blood. This study explored the longitudinal associations of physical activity and body fat with serum NGF and BDNF in children. Methods: Two waves of measurements were performed 2 years apart in 8- to 11-year-old children, including physical activity using the ActiGra

Stretching of DNA in nanoscale confinement allows for direct visualization of the genetic contents of the DNA on the single DNA molecule level. DNA stretched in nanoscale confinement also allows for studies of DNA-protein interactions and DNA polymer physics in confined environments. This chapter describes the basic steps to fabricate the nanostructures, to perform the experiments, and to analyze

Development in building envelopes and energy efficient systems has an impact in reducing energy use, but the everyday life of the households significantly influences the total performance of the housing sector that in Sweden constitutes 25% of the total energy use. This paper presents and discusses some results of a study investigating the relationship between every-day life and energy use among t

Behandlar gipsavgjutningarnas ställning och roll i konstutbildningen och på konstmuseerna från 1700-talet till 1914.

An estimation model which uses the gross heat release data and the fuel energy to estimate the total amount of emissions and unburned Hydro Carbon (HC) is developed. Gross heat release data is calculated from a self-tuned heat release method which uses in-cylinder pressure data for computing the energy released during combustion. The method takes all heat and mass losses into account. The method e
