A light pulse that travels through a narrow spectral window, i.e. a frequency range of low absorption, within a strongly absorbing frequency range will be delayed due to strong dispersion. If however, the absorbing structure is inverted, such that it is amplifying instead, one will see that a pulse travelling through this window will have its pulse peak come out of the material before it is sent i
We present and discuss the complete set of infrared-active phonon modes in monoclinic-symmetry crystal modification gallium oxide (gallia, β-Ga2O3). The phonon mode set is obtained from a comprehensive analysis of generalized spectroscopic ellipsometry data in the farinfrared and infrared spectral regions investigating various n-type electrically conductive single crystal samples with different fr
BACKGROUND: There was a decrease 1982-2001 in smoking during early pregnancy in Swedish women. We sought to determine whether there was a parallel decrease in socio-economic inequality in smoking. METHODS: Registry data indicating educational level and smoking status at first antenatal visit in all 2,022,469 pregnancies in Sweden 1982-2001 was analysed. Prevalence differences, odds ratios based on
This bachelor’s thesis in Historical Archaeology concerns how the royal medals of the Swedish King Gustav III (1756-1792) functioned as a means of political propaganda, namely in what ways an official legitimizing narrative was created about the country’s economy and the role of the King herein, through the images and texts of the royal medals. Inspired by Clifford Geertz’ anthropological perspec
Video capsule endoscopy (VCE), perfomed by ingesting a small vitamin-sized camera pill, was developed over a period of a couple of decades and –since its introduction in clinical practice at the dawn of the millennium– has become an essential tool in the diagnosis and management of small bowel (SB) diseases. At the same time, other fields such as minimally invasive diagnosis of other parts of the

In this paper we demonstrate how surface site specific experimental information can be obtained from free low nanometer scale clusters using photoelectron spectroscopy utilising synchrotron radiation. In addition, we show how it can be used to gain insight into the geometry and surface structure of the clusters. The present experiments were conducted on alkali metal halides, RbCl and CsCl, which w
Fredrik NG Andersson and Lars Jonung argue that the current push for fiscal activism is short-sighted. Instead, the Swedish case from the last 25 years shows that stable public finances combined with supply-side policies is the recipe for economic stability and growth.
This thesis will inquire into the contemporary neo-Yugoslavian culture in Sweden and cultural intimacy as a base to recreate the bonds from the past. Moreover, mutual impacts between the two substantially different societies, the society of free individuals of the Swedes and neo- Yugoslav collectiveness, duh Yuge, are the result of a multifaceted process with intriguing outcomes.

In this project, a neutron delivery system for the study of free neutron oscillations at the HIBEAM beamline at the European Spallation Source (ESS) has been developed. The HIBEAM experiment is part of a two-stage program at ESS which will address open questions in physics; specifically the nature of dark matter and the observed asymmetry between matter and antimatter in the Universe. This will be
The interplay between diet and immune-parameters which could affect type 1 diabetes (T1D) pathogenesis is not sufficiently clarified. Intestinal upregulation of the activating receptor NKG2D(CD314) and its ligands is a hallmark of celiac disease (CD). However, the direct effect of gluten on NKG2D expression is not known. We studied, by FACS (lymphoid tissues) and RT-qPCR (intestine and pancreatic
This paper presents fully ab initio calculations of the broadenings and spectral shapes of O-2 infrared absorption lines in a free gas and when confined in nanoporous media. These calculations are performed, without use of any adjusted parameter, using a recently proposed approach [Phys. Rev. A 87, 013403 (2013)] that is based on requantized classical molecular-dynamics simulations. This involves
INTRODUCTION: We studied whether adding percent free prostate-specific antigen (%fPSA) to total PSA improves prediction of clinically significant prostate cancer (csPCa) and fatal PCa.METHODS: 6727 men within the intervention arm of the Prostate, Lung, Colorectal and Ovarian Trial had baseline %fPSA. Of this cohort, 475 had csPCa and 98 had fatal PCa. Cumulative incidence and Cox analyses were con

Introduction: The scapular osseous free flap (SOFF) is being increasingly used for complex head and neck reconstructions. This study examined the surgical outcomes, focusing on post-operative complications and sequelae in patients who underwent SOFF for maxillary and mandibular reconstructions. Material and Methods: This retrospective, observational, population-based study included patients who un
