Some leading science programs undertaken with Very Large Telescopes and challenges driving the progress of the Extremely Large Telescopes are discussed together with the corresponding requirements. They concern expolanets, Earth-like planets, habitable zones, formation of stars and galaxies, first stars and cosmology. A description is attempted

Popular Abstract in Swedish Digital bildteknik dominerar snart all bildhantering inom alla delar av samhället. Målsättningen med denna avhandling var att utveckla en undersökningsmetod för mätning av knäleden i belastat läge med hjälp av digital bildplatteteknik. Vad är bildplatteteknik? Traditionellt har röntgenbilder framställts med hjälp av fotografisk film. De framkallade bilderna har sedan The overall aim of this study was to develop and evaluate a measurement system for computed radiography (CR) and Picture Archiving and Communication Systems (PACS), permitting measurements of long distances and angles in and between related images. The developed measurement system, which was based on the QUESTOR Precision Radiography (QPR) system, was applied to the weight-bearing knee with specia

In this work a compact fluorosensor has been built for point-monitoring and imaging applications. The instrument has been applied in fluorescence studies on green vegetation and on malignant tissue. The instrument is based on a violet diode laser, an integrated spectrometer and optical fibers for light delivery and collection of the fluorescence signal. This combination makes the system very compa

Breast cancer is the most common cancer in women worldwide, identification of new biomarkers for early diagnosis and detection will improve the clinical outcome of breast cancer patients. In the present study, we determined serum levels of vitronectin (VN) in 93 breast cancer patients, 30 benign breast lesions, 9 precancerous lesions, and 30 healthy individuals by enzyme-linked immunosorbent assay

BACKGROUND: The study was carried out to evaluate the expression of major histocompatibility complex (MHC) molecules in retinal transplants with different tissue integrity.METHODS: Twelve adult rabbits received an allogeneic subretinal neuroretinal transplant, in the form of either fragmented embryonic cells or a complete full-thickness embryonic retina. A controlled transvitreal approach was used

År 2001 deklarerade den tanzaniska regeringen den första Primary Education Development Plan och därmed avskaffades den tidigare obligatoriska skolavgiften för grundskolan. I och med avskaffandet av skolavgiften förväntades andelen barn i grundskola att öka. Syftet med avhandlingen är att förstå hur reformen och dess fokus på avskaffandet av skolavgiften har påverkat föräldrars och vårdnadshavares In 2001, the first Primary Education Development Plan declared that the previous obligatory primary education fee was to be abolished in Tanzania. This was an attempt to increase the access to public primary education for all children. This thesis aims to understand how the reform and its focus on the abolition of school fee influences parents’ and caregivers’ support for primary education and imp

This paper addresses Test Application Time (TAT)reduction for core-based 3D Stacked ICs (SICs). Applyingtraditional test scheduling methods used for non-stacked chiptesting where the same test schedule is applied both at wafer testand at final test to SICs, leads to unnecessarily high TAT. This isbecause the final test of 3D-SICs includes the testing of all thestacked chips. A key challenge in 3D-

The program system MOLCAS is a package for calculations of electronic and structural properties of molecular systems in gas, liquid, or solid phase. It contains a number of modern quantum chemical methods for studies of the electronic structure in ground and excited electronic states. A macromolecular environment can be modeled by a combination of quantum chemistry and molecular mechanics. It is f

OBJECTIVE: Increased inflammation and oxidative stress have been shown in Major Depressive Disorder (MDD), although there is significant heterogeneity across studies. Whether markers of inflammation and oxidative stress are associated with antidepressant treatment response in MDD is currently unclear. The goals of the present study are to investigate markers of inflammation and oxidative stress in

Background: Deferral of coronary revascularization is safe whether guided by instantaneous wave-free ratio (iFR) or by fractional flow reserve (FFR). We aimed to assess long-term outcomes in patients deferred from revascularization based on iFR or FFR in a large real-world population. Methods: From 2013 through 2017, 201,933 coronary angiographies were registered in the Swedish Web-System for Enha

BACKGROUND: In contrast with macroorganisms, that show well-documented biogeographical patterns in distribution associated with local adaptation of physiology, behavior and life history, strong biogeographical patterns have not been found for microorganisms, raising questions about what determines their biogeography. Thus far, large-scale biogeographical studies have focused on free-living microbe

Nursing homes are often places where older persons “come to die.” Despite this, death and dying are seldom articulated or talked about. The aim of this study was to explore assistant nurses’ experiences of conversations about death and dying with nursing home residents. This study is part of an implementation project through a knowledge-based educational intervention based on palliative care princ

Objective: The primary aim of this study was to investigate whether there was any difference in scores of the Cleft Hearing, Appearance and Speech Questionnaire (CHASQ) between patients with cleft lip and/or cleft palate (CL/P) and a control population. The second aim was to compare CL/P and control population scores in this study with a British norm CL/P population. Design: Single-site, cross-sec

Preclinical studies support an anticancer effect of statin drugs, yet epidemiologic evidence remains inconsistent regarding their role in breast cancer primary prevention. Here, we report an updated analysis of the association between statin use and breast cancer incidence in the Nurses' Health Study (NHS) cohort. Postmenopausal NHS participants without a cancer history were followed from 2000 unt

This article explores four preselected permanent magnet synchronous machine (PMSM) topologies suitable for direct mounting on low pressure spool in a turbo fan engine. The challenge of contributing to More Electric Engine (MEE) development is that the electrical machine needs to operate over wide speed range, take advantage of available space that forces to use a high number of poles and last but

Purpose: This study investigates the association between mean arterial pressure (MAP) and renal function after out-of-hospital cardiac arrest (OHCA). Materials and methods: Post-hoc analysis of 851 comatose OHCA-patients surviving >48 h included in the targeted temperature management (TTM)-trial. Results: Patients were stratified by mean MAP during TTM in the following groups; <70 mmHg (22%), 70–8
