Superconductivity in the presence of magnetic steps

This thesis investigates the distribution of superconductivity in a Type-II planar, bounded, and smooth superconductor submitted to a piecewise-constant magnetic field with a jump discontinuity along smooth curves---the magnetic edge. This discontinuous case has not been treated before in the mathematics literature, where the considered applied magnetic field is usually assumed to be smooth.We exa

Near-Field Measurement and Calibration Technique for RF EMF Exposure Assessment of mm-wave 5G Devices

Accurate and efficient measurement techniques are needed for exposure assessment of 5G portable devices---which are expected to utilize frequencies beyond 6 GHz---with respect to the radio frequency electromagnetic field exposure limits. Above 6 GHz, these limits are expressed in terms of the incident power density, thus requiring that the electromagnetic fields need to be evaluated with high prec

Structure and energetics of molecular recognition in galectin-3-ligand interactions

Molecular recognition is the key aspect of any cellular and biological function. Two or more molecules interacting with each other cause the effects that drives various basic functions that are fundamental to cells. Be these protein-protein, protein-nucleic acid or protein-ligand interactions, they all play important roles in a cell. Protein-ligand interactions are the most studied as they can havMolecular recognition is the key aspect of any cellular and biological function.

Transcriptome-wide association study of multiple myeloma identifies candidate susceptibility genes

BackgroundWhile genome-wide association studies (GWAS) of multiple myeloma (MM) have identified variants at 23 regions influencing risk, the genes underlying these associations are largely unknown. To identify candidate causal genes at these regions and search for novel risk regions, we performed a multi-tissue transcriptome-wide association study (TWAS).ResultsGWAS data on 7319 MM cases and 234,3

Embracing the future : path transformation and system reconfiguration for self-driving cars in West Sweden

The past years have witnessed a surge of academic interest into how new industrial paths are developed in regions. Transformation processes of existing regional industries have received less attention. This article focuses on radical innovation-based renewal processes of established paths and investigates how regional innovation systems are tackling challenges related to path transformation. Drawi

Encapsulation of Aspartic Protease in Nonlamellar Lipid Liquid Crystalline Phases

Encapsulation of proteins within lipid inverse bicontinuous cubic phases (Q2) has been widely studied for many applications, such as protein crystallization or drug delivery of proteins for food and pharmaceutical purposes. However, the use of the lipid sponge (L3) phase for encapsulation of proteins has not yet been well explored. Here, we have employed a lipid system that forms highly swollen sp

Offshore outsourcing : An IT-manager perspective on cultural differences

— Cultural difference is a term often used when discussing problems in offshoring and offshore outsourcing, but only a few authors discuss solutions to bridge pointed out cultural gaps. In this paper earlier research is compared with an IT-manager perspective on experienced cultural differences. Cultural differences were found to include multiple dimensions: cultural distances, cognitive distances

The differences in the T2 relaxation rates of the protons in the partially-deuteriated and fully protonated sugar residues in a large oligo-DNA (‘NMR-window’) gives complementary structural information

Selective incorporation of the stereospeciflcally deuterlated sugar moieties (\lt;97 atom \% 2H enhancements at H2′, H2″, H3′ and H5′/5′ sites, ∑85 atom \% 2H enhancement at H4′ and ∑20 atom \% 2H enhancement at H1′) in DNA and RNA by the ‘NMR-window’ approach has been shown to solve the problem of the resonance overlap [refs. 1, 2 \amp; 3]. Such specific deuterium labelling gives much improved re

Localization and Regulation of Polymeric Ig Receptor in Healthy and Diseased Human Kidney

The polymeric Ig receptor (PIgR) constitutes an important part of the immune system by mediating transcytosis of dimeric IgA into mucosal fluids. Although well studied in organs such as the intestine, the regulation and localization of PIgR in human kidney are incompletely characterized. Herein, using immunohistochemistry, we show that in healthy human kidneys, PIgR is expressed by the progenitor-

The wealth of the Swedish peasant farmer class (1750-1900) : Composition and distribution

Using about 1,730 probate inventories, this article studies the wealth of peasant farmers in Sweden for the years 1750, 1800, 1850 and 1900. Average wealth grew rapidly, tripling over the nineteenth century, but it did not grow equally: the Gini coefficient for the farmers' wealth grew from 0.46 in 1750 to 0.73 in 1900. Farmers who lived close to the major grain markets in Stockholm and the mining

Telomere Biology and Vascular Aging

Telomeres form the end segment of the DNA helix and shorten with every cell division until getting so short that the cell stops dividing and will undergo programmed cell death (apoptosis). Research has supported the view that telomere length could be regarded as a marker of biological aging, even if methodological problems could interfere with the interpretation of telomere length in cross-section

CPAP and health-related quality of life in adults with coronary artery disease and nonsleepy obstructive sleep apnea in the RICCADSA trial

Study Objectives: To determine the effect of continuous positive airway pressure (CPAP) treatment on health-related quality of life (HRQoL) in adults with coronary artery disease (CAD) and nonsleepy obstructive sleep apnea (OSA). Methods: This was a secondary outcome analysis of the RICCADSA trial, conducted in Sweden between 2005 and 2013. Adults with CAD, nonsleepy OSA (apnea-hypopnea index [AHI

The rate and perioperative mortality of caesarean section in Sierra Leone

Introduction Sierra Leone has the world's highest maternal mortality, partly due to low access to caesarean section. Limited data are available to guide improvement. In this study, we aimed to analyse the rate and mortality of caesarean sections in the country. Methods We conducted a retrospective study of all caesarean sections and all reported in-facility maternal deaths in Sierra Leone in 2016.

Clinical and angiographic outcomes of bioabsorbable vs. permanent polymer drug-eluting stents in Sweden : a report from the Swedish Coronary and Angioplasty Registry (SCAAR)

Aims: Randomized clinical trials have consistently demonstrated the non-inferiority of bioabsorbable polymer drug-eluting stents (BP-DES) with respect to DES having permanent polymers (PP-DES). To date, the comparative performance of BP- and PP-DES in the real world has not been extensively investigated. Methods and results: From October 2011 to June 2016, we analysed the outcomes associated with
