This thesis aims to contribute to the field of time controlled charge and energy transport in mesoscopic systems. In Chapter 1, Chapter 2 and Chapter 3 a short review of the scattering matrix theory is presented, including both charge and energy transport, useful to understand the mathematical landscape used in Papers I, II, III and IV. Chapter 3 briefly presents the thermoelectric properties of m
Borreliosis is known to be a common cause of peripheral facial palsy in Stockholm and its vicinity. The aim of the present study was to investigate the frequency and characteristics of borreliosis among patients with peripheral facial palsy in different parts of Sweden. All serological tests were performed in one laboratory. Ten Swedish Ear Nose and Throat clinics participated in a prospective 1-y

Preeclampsia, one of the leading causes of pregnancy complications, affects 3-7% of pregnant women. This review summarizes the present knowledge of a new potential cause of the disease and suggests a method for its prediction/diagnosis and a possible treatment, both based on the recent findings on the involvement of fetal hemoglobin (HbF) and the heme and radical scavenging protein A1M (alpha-1-mi
OBJECTIVE: We first studied whether changes of needs were influenced by randomly allocated telephone interventions between 1 and 12 months after a suicide attempt in addition to treatment as usual. These were aimed at improving motivation for professional treatment. As a secondary analysis we investigated the frequency and changes of needs during this period and if changes were related to other ou
Studies of ornaments as indicators of individual quality have hitherto focused on males, while studies of female ornaments have been almost absent. However, females within the same species may show large variation in both outer appearance and individual quality. We experimentally examined the effect of an immune challenge on the size of white fringes in the wing feathers produced one to two months
An U-L-rhamnosidase (E.C. 3.2.1.40) from a newly discovered thermophilic bacterium was expressed in Escherichia coli BL21 DE3 pRIL cells. The cells were immobilized in Ca2+-alginate beads. The temperature of 50 degrees C used in reactions, appeared to be sufficient for making the mesophilic strain porous enough for the substrate to access the cloned thermostable enzyme. Pretreatment of cells with
A process-oriented, performance-based cost-model for manufactured parts has been assessed in its ability to capture sustainability. Literature has been reviewed and found 108 sustainability indicators, which have been compared with the input parameters in the cost-model. Based on a gap analysis, a framework for sustainable production evaluation has been developed. The framework considers performan
Children using mechanical ventilation for survival represent a small, but growing, vulnerable population in society. The aim of this study was to describe the existing qualitative research that examined family members' experiences when a child is dependent on ventilator at home. A metasynthesis is an interpretative integration of qualitative research findings based on a systematic literature searc
In this study we describe combustion simulations of a single sector and a fully annular generic multi-burner aero-engine combustor. The objectives are to facilitate the understanding of the flow, mixing and combustion processes to help improve the combustor design and the design process, as well as to show that it is now feasible to perform high-fidelity reacting flow simulations of full annular g
This study analyses the perceived key interests, importance, influences and participation of different actors in harmonizing the processes and mechanisms of a distributed research infrastructure. It investigates the EU-funded initiative, BioBanking and Molecular Resource Infrastructure in Sweden (BBMRI.se), which seeks to harmonize the biobanking standards. The study interviews multiple actors inv
In a socio-technical work domain, humans, device interfaces and artefacts all affect transformations of information flow. Such transformations, which may involve a change of auditory to visual information & vice versa or alter semantic approximations into spatial proximities from instruments readings, are generally not restricted to solely human cognition. This paper applies a joint cognitive
Objective: To compare a wearable device, the Fitbit Versa (FV), to a validated portable single-channel EEG system across multiple nights in a naturalistic environment. Methods: Twenty participants (10 men and 10 women) aged 25–67 years were recruited for the present study. Study duration was 14 days during which participants were asked to wear the FV daily and nightly. The study intended to reprod
This study is an extension of previous studies, Hagnell (1991) and Hagnell(1996), where the data used are annual time series for the whole of Sweden during the period 1751-1850 for the crude birth rate, the death rate for ages 20-50 years, the crude marriage rate and an index of the real wages. The aim of the study of Hagnell (1991) was to investigate the relationships between ferility, adult mort
Low body mass index (BMI) is a well-documented risk factor for future fracture. The aim of this study was to quantify this effect and to explore the association of BMI with fracture risk in relation to age, gender and bone mineral density (BMD) from an international perspective using worldwide data. We studied individual participant data from almost 60,000 men and women from 12 prospective populat

Today's Carrier-Envelope Phase (CEP) stabilizations of mode-locked oscillators widely used in attosecond science and frequency metrology rely on octave spanning frequency combs and the detection of beating between the blue end and the frequency doubled red end of the same spectrum. This technique was established by the seminal works of Hänsch and co-workers [1], demonstrating the stabilization of
