Scattering-matrix formalism of electron transport through three-terminal quantum structures: formulation and application to Y-junction devices

In this paper we present a formalism for the calculation of electron transport through three-terminal junction devices, which have received attention due to their recently demonstrated non-linear electrical properties. The formalism, which is based on the scattering-matrix method, takes quantum interference effects fully into account. Furthermore, the formalism provides numerical stability in the

On the nature and expression of prejudice as seen in judgments of pictorial stimuli.

In Study 1 (N = 120), pictures of violent behavior taking place within or between ethnic groups were rated under different instructions. A strong cross-over effect was found: interracial violence was reported as relatively more threatening under the instruction that the study concerned anxiety, whereas violence among Whites was reported as more threatening under the instruction that the study conc

Engagemang i Lutherhjälpen : studier av motiv och drivkrafter hos frivilligt aktiva

Popular Abstract in Swedish Del 1. Introduktion I kapitel 1 presenteras arbetets problem, syfte och metod. Det arbete som olika frivilligorganisationer och deras medlemmar utför har de senaste åren uppmärksammats alltmer. Detta ökade intresse finner man såväl i Sverige som internationellt. Fokus i detta arbete riktas mot drivkrafterna bakom frivilligt engagemang. Det övergripande problemet är varfThis thesis focuses on the incitement to commitment and voluntary work. The overall problem is the question why you get involved in voluntary work for an organisation like Lutherhjälpen, the organisation for international development co-operation of the Church of Sweden, one of the largest NGOs of the country. The theoretical perspectives are seen from the position of the increasing pace of change

An experimental and theoretical study of the morphine binding capacity and kinetics of an engineered opioid receptor

Electrochemical real-time monitoring of ligand binding to an engineered opioid receptor specific for morphine is reported. In the particular systems studied, 90% of the binding was found to be completed after only 85-120 s. Thus, the binding kinetics has proven to be more rapid than previously believed. The observed association rate constant for the morphine binding reaction was calculated to be 2

Aristokratiskt rum och gränsöverskridande. Järrestad och sydöstra Skåne mellan region och rike 600-1100

Popular Abstract in Swedish Avhandlingen fokuserar på den andra vågen av järnålderns centrala platser, vilka formerades under det långa 600-talet. Utgångspunkten är en fallstudie av en aristokratisk miljö i Järrestad, sydöstra Skåne. Två problemkomplex bearbetas. Tolkningen av de förkristna aristokratiska miljöerna. Syftet är att undersöka hur härskarideologier gestaltades i hallmiljön och det omThis dissertation focuses on the second wave of central places in south Scandinavia, emerging during the prolonged 7th century. The point of departure is a case study of an aristocratic setting in Järrestad, situated in the southernmost part of Sweden. Two problem complexes are tackled: 1. The interpretation of the pre-Christian aristocratic settings. The aim is to investigate the staging of rule

Improvement in cardiac systolic function and reduced prevalence of metabolic syndrome after 2 years of GH treatment in GH deficient adult survivors of childhood acute lymphoblastic leukaemia.

Context: Survivors of childhood- onset ( CO) acute lymphoblastic leukemia ( ALL) treated with prophylactic cranial radiotherapy often exhibit GH deficiency ( GHD), which is associated with increased prevalence of cardiovascular risk factors and cardiac dysfunction. Objective: The objective of the study was to evaluate the effect of GH replacement on cardiovascular risk factors and cardiac function

Methodological study of affine transformations of gene expression data with proposed robust non-parametric multi-dimensional normalization method

Background: Low-level processing and normalization of microarray data are most important steps in microarray analysis, which have profound impact on downstream analysis. Multiple methods have been suggested to date, but it is not clear which is the best. It is therefore important to further study the different normalization methods in detail and the nature of microarray data in general. Results: A

Fire behaviour of beds and upholstered furniture - an experimental study (Second test series) Part 1

A series of twelve full scale experiments with upholstered furniture and beds has been carried out. Ten experiments were performed inside an extensively equipped compartment with a door opening. In order to study the influence of the room on the fire development two experiments were carried out in the open outside the compartment. One experiment in the room was made with restricted ventilation sim

Method to assess acoustical two-port properties of earplugs

An experimental setup for objective measurements of high impedance objects in ducts, yielding the acoustical Two-Port properties of the object, is presented. The setup has been applied on earplugs. A frequently used experimental setup for measuring objective acoustical properties of earplugs is that of artificial ears. Great effort is spent duplicating the ear of a person. The insertion loss is co

Macroscopic alignment of silver nanoparticles in reverse hexagonal liquid crystalline templates

A flexible method of preparing and macroscopically aligning nanoparticles of crystalline silver into millimeter long fibers is presented. The approach utilizes the dual functionality of a reverse hexagonal liquid crystalline template containing a built-in reducing agent facing the aqueous domain. The method is advantageous in that its slow kinetics allows for a thorough introduction of a silver sa

Flame retardant exposure: polybrominated diphenyl ethers in blood from Swedish workers.

Polybrominated diphenyl ethers (PBDEs) are used as additives in polymers and textiles to prohibit the development of fires. Because of the production and use of PBDEs, their lipophilic characteristics, and persistence, these compounds have become ubiquitous environmental contaminants. The aim of the present study was to determine potential exposures of PBDEs to clerks working full-time at computer

Pain induced by propofol - clinical studies on drug composition and adminstration

Popular Abstract in Swedish De senaste 25 åren har flera nya narkosläkemedel registrerats och fått stort genomslag i vårt land. Den främsta orsaken är att dessa läkemedel medger ett snabbare uppvaknande och bättre postoperativt välbefinnande, vilket gör att många patienter snabbare kan återvända hem efter sina operationer. Propofol (2,6-di-isopropylfenol) som är ett av våra mest använda intra-venöOver the last 25 years a number of new anaesthetic drugs have been introduced on the market to allow for better patient satisfaction and faster recovery after anaesthesia and sedation. Propofol (2,6-di-isopropylphenol), one of our most common iv anaesthetics, is associated with pleasant sleep and rapid recovery with little postoperative nausea. When used for anaesthetic induction propofol causes s

Use of history science methods in exposure assessment for occupational health studies

Aims: To show the power of history science methods for exposure assessment in occupational health studies, using the dry cleaning industry in Denmark around 1970 as the example. Methods: Exposure data and other information on exposure status were searched for in unconventional data sources such as the Danish National Archives, the Danish Royal Library, archives of Statistics Denmark, the National

Oscillator strengths and hypertine structures in GaII from multiconfiguration Dirac-Hartree-Fock calculations

We report relativistic multiconfiguration Dirac-Hartree-Fock calculations of oscillator strengths and hyperfine structures for a large number of electric dipole transitions in Ga II. Results for the 4s(2) S-1(0)-4s4p 3P(0)(o) hyperfine-induced transition are also given. Core polarization is accounted for by means of explicit CI. To describe spin and orbital polarization, which are important for th
