Our aim was to analyze risk of first hospital diagnosis of asthma in children (< 10 years) and adolescents (10 through 19 years) in Sweden between 1970 and 2004 by parental occupation, controlling for potential confounders. Data from the Multigeneration Register, in which all children born in Sweden from 1932 onward are registered with their parents, were linked to nationwide Hospital Register dat
Today, the car industry has become one of the greatest users of both wireless and cellular technologies and is increasingly dependent especially in the area of wireless communication. Communication among vehicles is offering a lot of benefits and has testified improvement on safety, efficiency and possible automation of the traffic. A lot of research has been focused on measurement campaigns, by i
Syftet med studien var att undersöka förhållandet mellan självförverkligande, socialt jämförande och motivation. För socialt jämförande mättes både en generell benägenhet och benägenhet att jämföra i olika riktningar (uppåt eller nedåt). Den operationella definitionen för motivation utgick ifrån de kausalitetsorienteringar som återfinns inom self-determination theory. Datainsamling skedde i form aThe purpose of this study was to investigate the relationship between self actualization, social comparison, including upward and downward comparison, and different types of motivation as defined by the proposed causality orientations within self determination theory. Data was acquired through a survey distribution. The sample consisted of a convenience sample (N=131). The results, from a correlat

Connecting science to political agenda-setting is essential for a sustainable transition and acceptable politics. This task is complicated by phenomena like post-truth, for which facts are a non-issue. However, post-truth is not the only issue. The practice of political spin, in which the significance of facts is reconstructed according to specific interests poses another threat to scientific cred
Body-mass index (BMI) has become the standard proxy for obesity in social science research. This study deals with the potential problems related to, first, relying on self-reported weight and height to calculate BMI (misreporting), and, second, the concern that BMI is a deficient measure of body fat (misclassification). Using a regional Swedish sample, we analyze whether socioeconomic disparities
Acoustic standing wave technology combined with microtechnology opens up new areas for the development of advanced particle and cell separating microfluidic systems. This tutorial review outlines the fundamental work performed on continuous flow acoustic standing wave separation of particles in macro scale systems. The transition to the microchip format is further surveyed, where both fabrication
Comparison of two-particle correlations in heavy-ion collisions with measurements in proton collisions shows strong modification of the correlation shape and particle yields. Two new structures are created; both extended in Δη, one centered at Δ = 0 ('ridge') and the other occurring at Δ π ± 1.1 ('shoulder'). In these proceedings, we describe the measurements of these structures that show consiste
We have fabricated single balanced down-conversion mixer circuits using InAs nanowire MOSFETs as both active and passive devices. This is achieved by a combination of electron beam lithography and UV-lithography with a line width of 12 mu m. The circuits exhibit a low frequency voltage conversion gain of 6 dB, a -3 dB cutoff frequency of 2 GHz and a power consumption of 3.8 mW, while operating at
An active single balanced down-conversion mixer is implemented using InAs nanowire metal oxide semiconductor field effect transistors (MOSFETs) as both active devices and passive resistive loads. Circuits with 6 dB low-frequency voltage gain and a 3 dB bandwidth of 2 GHz are measured for a DC power consumption of 3.8 mW from a 1.5 V supply. The circuits are fabricated using contacts made with 12 μ
This review article focuses on advances and technical developments of the realm of membrane extraction techniques for the analytes that are (made) amenable to gas chromatographic analysis, and sheds light on the analytical applications to biological and environmental samples. In this review, the state of the art in this growing area of membrane extraction for gas chromatography is presented and se
During the last years evaluation has been on the agenda as a part of the discourse in social work and social services in Sweden. This demand on evaluation and the value of the social work is connected to the tough economic situation in the municipalities and their growing responsibility for the social welfare services. At the same time there are strivings to improve the quality of social work and
We report lifetime measurements for three of the 5d(9)6p levels in An II and relativistic multiconfiguration Dirac-Fock (MCDF) calculations of lifetimes and transitions probabilities in this ion. The work was motivated by significant disagreements between previous experimental 5d(9)6p lifetimes, obtained by means of the beam-foil (BF) method and theoretical data based on Hartree-Fock calculations
The present investigation examined motivation for parenting and some of its correlates in parents and children. The data came from samples of 151 first-time mothers of infants, 153 mothers of middle school children, and 260 mothers and fathers of high school children. Parents provided self-report data about their motivation in their parenting role as well as reports of role satisfaction, parental
Integration of III-V semiconductors on Si substrates allows for the realization of high-performance, low power III-V electronics on the Si-platform. In this work, we demonstrate the implementation of single balanced down-conversion mixer circuits, fabricated using vertically aligned InAs nanowire devices on Si. A thin, highly doped InAs buffer layer has been introduced to reduce the access resista
