Calibration factor for determination of interstitial oxygen concentration in germanium by infrared absorption

Intensities of infrared absorption due to asymmetric stretching vibrations of interstitial oxygen atoms in Ge crystals enriched with O-16 and O-18 isotopes have been compared with oxygen concentrations determined by means of secondary ion mass spectrometry (SIMS). For Ge samples with oxygen content less than 510(17) cm(-3) a good correlation has been found between the values of oxygen concentratio

Treatment of arthritis with tumour necrosis factor antagonists. Clinical, immunological and biochemical aspects

Popular Abstract in Swedish Reumatoid artrit (kronisk ledgångsreumatism; RA) är en inflammatorisk sjukdom där lederna är det primära målorganet. Spondylartropatier är ett gemensamt namn för ett flertal kroniska inflammatoriska sjukdomar med många gemensamma tecken som till exempel: inflammatorisk ryggsmärta, inflammationer i leder, senskidor, muskelfästen, förekomst av "orvfingrar/-tår". Orsaken/eAbstract The treatment of arthritis has undergone a dramatic change since biological agents targeting specific mediators of the disease process have been introduced. Tumour necrosis factor (TNF) antagonists have been shown to reduce signs and symptoms of disease and to retard the development of tissue damage in the majority of patients. This thesis focuses on clinical, immunological and biochemic

Radiation enteropathy and leucocyte-endothelial cell reactions in a refined small bowel model

BACKGROUND: Leucocyte recruitment and inflammation are key features of high dose radiation-induced tissue injury. The inflammatory response in the gut may be more pronounced following radiotherapy due to its high bacterial load in comparison to the response in other organs. We designed a model to enable us to study the effects of radiation on leucocyte-endothelium interactions and on intestinal mi

Drought acclimation and lipid composition in Folsomia candida: implications for cold shock, heat shock and acute desiccation stress

Many of the physiological adaptations evolved in terrestrial invertebrates to resist desiccation have also been shown to enhance the survival of low temperatures. In this study we have examined temporal changes in the physiology of the collembolan Folsomia candida during acclimation to mild desiccation stress (98.2% RH), and how physiological changes correlate with resistance to subsequent cold sh

Tryckpressens makt och makten över tryckpressen : om tryckerietableringar i det svenska riket 1600-1650

After a century of Swedish State monopoly of printing, with only one printing office, that of the Royal Printer in Stockholm, the beginning of the 17th century marks a spread of establishments over the realm. This is a conscious change in Government media policy. Around 1650 there were nine printing shops active in Sweden, six of these in provincial towns with universities or diocesan schools, but

A Study of High-spin States in the Transitional Nucleus 90Mo

The reaction Ni-58(Ar-36, 4p)Mo-95 has been studied at a beam energy of 149 MeV A detector array consisting of the OSIRIS spectrometer (12 Compton-suppressed Ge detectors), four charged-particle DELTA-E detectors and seven NE-213 neutron detectors at the VICKSI accelerator in Berlin has been used to measure the gamma radiation in gamma-gamma- and particle-gamma-gamma-coincidence mode. An additiona

The Hamburg/ESO R-process Enhanced Star survey (HERES). I. Project description, and discovery of two stars with strong enhancements of neutron-capture elements

We report on a dedicated effort to identify and study metal-poor stars strongly enhanced in r-process elements ([r/Fe]>1 dex; hereafter r-IIstars), the Hamburg/ESO R-process Enhanced Star survey (HERES).Moderate-resolution (∼2 Å) follow-up spectroscopy has been obtained for metal-poor giant candidates selected from the Hamburg/ESO objective-prism survey (HES) as well as the HK survey to identify s

Parsifal – ett mångtydigt konstverk

Som svar på en artikel av Magdalena Hedman i SKT nr 41-42, som menat att Wagners Parsifal inte är ett kristet verk utan snarare ett nyandligt, hävdar jag att det är ett mångtydigt, romantiskt konstverk, som inte kan kallas nyandligt, utan snarare står i en hermetisk, kristet inspirerad tradition, och att Parsifal i sitt kulturella sammanhang kan förmedla kristen inspiration. Inte självhjälp (som h

Methods and Tools for Analysis and Optimization of Power Plants

Modern societies' functionality is strongly dependent on the electricity. Efficient, environment friendly, and economical power production has been in focus for a long time. The introduction of computers and thereby computer-aided tools for pre-design studies, optimization and choice of the best operational strategies, has changed the conditions for power production tremendously. The most noticeab

Basic helix-loop-helix proteins expressed during early embryonic organogenesis.

The basic helix–loop–helix proteins form a special group of transcription factors unique for the eukaryotic organisms. They are crucial for the embryonic development of many fundamental organ systems such as muscle, heart, central nervous system, hematopoiteic system, and many others. They are very flexible in terms of regulating transcription in that they can either promote or repress transcripti

At what hip fracture risk is it cost-effective to treat? International intervention thresholds for the treatment of osteoporosis

Introduction: Intervention thresholds (ITs), the 10-year hip fracture risk at which treatment can be considered to be cost-effective, have previously been estimated for Sweden and the UK. Objective: The aim of this study was to provide a Markov cohort model platform for a multinational estimation of thresholds at which intervention becomes cost-effective and to investigate and determine the main f

Icelandic Case-marked PRO and the licensing of lexical arguments

On the basis of evidence from Icelandic I argue that PRO can be both governed and case-marked, but crucially not properly governed. Lexical arguments must be both case-marked and properly head governed, and proper head government is a strictly local relation whereas case-marking is not. As the subiect position of PRO clauses is not properly head governed, it must not be lexicalized, irrespective o

Campylobacter jejuni in black-headed gulls (Larus ridibundus): Prevalence, genotypes, and influence on C. jejuni epidemiology

Campylobacteriosis is a zoonotic disease in which birds have been suggested to play an important role as a reservoir. We investigated the prevalence of Campylobacter jejuni subsp. jejuni in black-headed gulls (Larus ridibundus) in southern Sweden with the aim of examining the nature of C. jejuni infection in this bird species. Birds were sampled in four sampling series each year during 1999 (n = 4

Simulated Fires in Substances of Pesticide Type

In order to characterise fires in chemical warehouses, 38 medium scale experiments have been conducted. The experiments were performed in a 0.66m3 combustion chamber. On-line measurements were made of combustion gases (CO2, CO, HC and NOx), mass loss, smoke, temperatures, external radiation and phi-values. Intermittently gas and soot samples were collected and analysed for content of organic compo
