Time-domain material characterization using a leaky lens antenna and an in-house fabricated millimeter-wave wavelet generator using III-V technology is investigated. The wavelet generator produces short high-frequency pulses and is connected to a wideband and non-dispersive leaky lens antenna. A purely time-domain methodology is used to extract the complex permittivity of non-dispersive and non-ma
We investigate the static and dynamical behavior of 1D interacting fermions in disordered Hubbard chains, contacted to semi-infinite leads. The chains are described via the repulsive Anderson-Hubbard Hamiltonian, using static and time-dependent lattice density-functional theory. The dynamical behavior of our quantum transport system is performed via an integration scheme available in the literatur
Scots pine tree-ring width (TRW) data from Jamtland in the Central Scandinavian Mountains has been used to reconstruct summer temperatures back to 1630 BC. However, it was recently shown that this reconstruction was of limited spatial importance. In this paper, we aim to explain this limitation in the TRW data as a temperature proxy, as well as assess the temperature information from new maximum l
In this paper we are concerned with the convergence analysis of splitting methods for nonautonomous abstract evolution equations. We introduce a framework that allows us to analyze the popular Lie, Peaceman-Rachford and Strang splittings for time dependent operators. Our framework is in particular suited for analyzing dimension splittings. The influence of boundary conditions is discussed.
Abstract in UndeterminedThe popularity of the Internet and marketers' increased investments in Internet advertising have raised some questions concerning a marketer's power to influence children and young people's consumption through new media technology. This article, based on a recent explorative study of 15-year-old Swedish teenagers, aims to discuss their exposure-potential, actual, and percei
The purpose of this thesis has been to study biological and social factors of importance for Attention Deficit Hyperactivity Disorder (ADHD). Thirty children (age 6-11) with ADHD were examined with parent ratings, neurological examination, cognitive testing, cerebral blood-flow, and EEG. These children together with 14 other children the same age with ADHD, were video-taped during family-tasks be
Capabilities-based planning and capability assessment are high on the agendas of several countries and organisations as part of their risk management and emergency preparedness. Despite this, few definitions of capability exist, and they are not easily related to concepts such as risk, vulnerability and resilience. The aim of the present study was thus to broaden the scientific basis of the risk f
The transverse momentum (p(T)) spectra and ratios of identified charged hadrons (pi(+/-), K-+/-, p, (p) over bar) produced in root s(NN) = 200 GeV Au + Au and d + Au collisions are reported in five different centrality classes for each collision species. The measurements of pions and protons are reported up to p(T) = 6 GeV/c (5 GeV/c), and the measurements of kaons are reported up to p(T) = 4 GeV/
Deputation compounds (DCs) are added to passive air samplers (PAS) prior to deployment to account for the wind-dependency of the sampling rate for gas-phase compounds. This correction is particularly useful for providing comparable data for samplers that are deployed in different environments and subject to different meteorological conditions such as wind speeds. Two types of PAS-the polyurethane
Based on the constructivist international relations (IR) approach, the authors study Sweden’s engagement with the DPRK as a unique case to understand motivations for engaging in a so-called fragile state. Besides having its embassy in Pyongyang and serving as a protecting power for the U.S., Sweden has provided capacity building programs for North Korean government officials and scholars. It has a
Reproductive events are associated with important physiologic changes, yet little is known about how reproductive factors influence long-term health in women. Our objective was to assess the relation of reproductive characteristics with all-cause and cause-specific mortality risk.
This study aimed at examine the number of planned and acute hospital admissions during 1 year among people 65+ and its relation to municipal care, outpatient care, multimorbidity, age and sex. Four thousand nine hundred and seven individuals having one or more admissions during 2001 were studied. Data were collected from two registers and comparisons were made between those having one, two and thr
This paper deals with the varying roles of producer services in economic transformation during the last 30 years in Sweden, and analyses unique longitudinal data on eight service sectors. The theoretical background for the analysis is inspired by the technology shift thesis of economic historians, and we show that the renewal and transformation of producer services has taken place later than for t
Despite a broad theoretical literature on multidimensional inequality and a widespread belief that welfare is not synonymous to income - not the least in a developing context - empirical inequality examinations rarely include several welfare attributes. We explore three techniques on how to evaluate multidimensional inequality using Zambian household data on consumption, education, health and land
Popular Abstract in Swedish Sambanden mellan kostens sammansättning och risk för hjärt-kärlsjukdom är i många fall oklara. En kost rik på fleromättade fettsyror har ansetts kunna ge skydd mot hjärt-kärlsjukdom, men resultaten från olika studier är motstridiga. En anledning till detta kan vara för att man inte har tagit hänsyn till de genetiska skillnader som finns mellan individer. Omega-3 och oIn previous studies, a high quality diet has been associated with a reduced risk of cardiovascular disease (CVD) compared to a low diet quality, and specific “healthy” diet components, such as polyunsaturated fatty acids (PUFAs), have been hypothesized to reduce the risk of CVD. However, results from epidemiological studies have been conflicting. This may be due to individuals having varied geneti
The logic of the two principal ways of defining a genre - the classificatory and the historical is described. The problems concerning the classificatory definitions are analyzed. The distinction natural language and meta-language is evoked,and the fact that natural languages is defying this distinction,always mixing the levels,the classificatory genres do not. The historical genres belong to the n
Summertime measurements of CO2 and CH4 fluxes were carried out over a range of high-arctic ecosystem types in the valley Zackenbergdalen since 1996 using both chamber and eddy covariance methodology. The net ecosystem CO2 exchange and CH4 flux data presented reveal a high degree of inter-annual variability within the dominant vegetation types in the valley, but also show distinct differences betwe
Det övergripande syftet med avhandlingen var att belysa och kontextualisera fysioterapeutiska insatser för personer med schizofreniforma psykoser utifrån aktuell forskning om psykomotorisk funktion och självmedvetande. Självmedvetandeforskning, både experimentell och fenomenologisk, kopplar de mest grundläggande självmedvetandenivåerna till vårt kroppsliga ursprung; hur vi via den sensomotoriska f
