Weakly coupled relaxors based on compositions (1-x) BaTiO 3 -xBiMeO 3 , where Me is a metal ion, have attracted attention as potential candidates for high-temperature high-energy density capacitors. However, the necessary Bi content is typically high with x = 0.3-0.4. In order to reduce problems associated with compatibility for base metal electrodes and due to additional problems due to Bi vol

Introduction: For fast and effective antibiotic therapy of serious infections like sepsis, it is crucial with rapid information about antibiotic susceptibility, especially in a time when the number of infections caused by multi resistant bacteria has escalated in the world. Methods: Here, we have used a semi-quantitative MALDI-TOF-MS based method for antibiotic resistance detection, MBT-ASTRA™, wh

This thesis addresses how verbal comprehension is affected by seeing the speaker and in particular when the speaker is an animated virtual speaker. Two people visually co-present – one talking and the other listening, trying to comprehend what is said – is a central and critical scenario whether one is interested in human cognition, communication or learning. Papers I & II are focused on the e

The introduction of a mollecular method to identify the Entoviruses based on the amplification sequecing and phylogenetic analysis of protein VPI was described. It was proved that this method reduces significantly the time required for the identification of the isolated Entoviruses and that it is very useful in the characterization of isolates which are difficult to typify by the routine immunoloi

INTRODUCTION: 360-degree evaluations are used as an assessment in order to identify strengths and weaknesses of, or as a continuous evaluation for, residents. The aim of this study was to investigate the relationship between personality and ratings on 360-degree evaluations among surgical residency applicants. A secondary aim was to describe the personality profile of applicants for a surgical res

Abstract in UndeterminedIntestinal epithelial cells (IECs) play a key role in Crohn's disease, a chronic inflammatory bowel disease which requires invasive examinations to be diagnosed. The comparison of the cellular protein expression profiles of Crohn's disease patients and healthy subjects is fundamental for the identification of proteins clinically relevant as new biomarkers or as drug targets

BACKGROUND. Recently, the gene for cysteine-rich secretory protein 3 (CRISP-3) was reported to be highly upregulated in prostate cancer (PCa) compared to benign prostatic tissue. The current aims were to investigate diagnostic use of tissue expression and immunodetection in serum of CRISP-3 for detection or monitoring of PCa. METHODS. Radical prostatectomy specimens and tissue microarrays from tra

Tapasin (Tpn) is an ER chaperone that is uniquely dedicated to MHC-I biosynthesis. It binds MHC-I molecules, integrates them into peptide-loading complexes, and exerts quality control of the bound peptides; only when an "optimal peptide" is bound will the MHC-I be released and exported to the cell surface for presentation to T cells. The exact mechanisms of Tpn quality control and the criteria for

The Torrabaai-Koigabmond Complex (southern Kaoko Belt, Namibia) consists of three main intrusive rock types including metaluminous hornblende- and titanite-bearing quartz diorites, metaluminous hornblende- and biotite-bearing granodiorites and peraluminous garnet- and muscovite-bearing leucogranites. Uranium-Pb zircon data obtained on the granodiorites and leucogranites indicate concordia upper in

Knowledge-management has a long history in the work place enacted variously as apprenticeship, corporate libraries, and professional training programs. As an academic topic, it first appeared after Nonaka's (1991) paper. Western authors on knowledge-management generally treat "knowledge" and "information" as some kind of a commodity. "Knowledge" and "information" are thought to be acquired and tra

This thesis, which is based on four original papers, deals with human dendritic cells (DCs) in immunity and allergy. DCs play a key role in the regulation of immune responses by acting as the sentinels of the immune system, specialized in the uptake of a diverse range of antigens. These cells migrate to local lymph nodes and become highly efficient in inducing T cell proliferation, thus inducing a

This paper illustrates a novel method to analyze artificial neural networks so as to gain insight into their internal functionality. To this purpose, the elements of a feedforward-backpropagation neural network, that has been trained to detect edges in images, are described in terms of differential operators of various orders and with various angles of operation.

In 1998 renewable energy sources supplied 56 ± 10 exajoules,or about 14 percent of world primary energy consumption. Thesupply was dominated by traditional biomass (38 ± 10 exajoules a year. Other major contributions came from large hydropower (9 exajoules a year) and from modern biomass (7 exajoules). The contribution of all other renewables — small hydropower, geothermal, wind, solar, and marine

Background: Blunted nocturnal blood pressure dipping (NBPD) as well as high variability in blood pressure (BPV) and low variability in heart rate (HRV), are associated with increased cardiovascular morbidity and mortality. The aim of this study was to determine whether these traits are heritable. Methods: We studied 260 healthy siblings without antihypertensive drugs from 118 Swedish families. The
