This report presents positive infrared spectroscopic identification of H2O3, a higher oxide of hydrogen of importance for the understanding of the chain formation ability of atomic oxygen and a possible intermediate in hydrogen oxygen radical chemistry. All fundamental vibrations of H2O3, isolated in an argon matrix, have been observed. In addition, several bands of HDO3, D2O3, and H2(16)O2(18)O h
In the present study, a phage display library covering the genome of Staphylococcus lugdunensis, was affinity-selected against von Willebrand factor (vWf). This led to the identification of a gene, vwbl, encoding a Putative cell surface protein of 2060 amino acids, denoted vWbl. The deduced protein has an overall organisation typical of staphylococcal cell Surface proteins, with an N-terminal sign
The purpose of the present study was to assess the role of diffusion and convection during filtration of Ficoll across the glomerular filter by comparing glomerular sieving coefficients ( h) to neutral fluorescein isothiocyanate ( FITC)-Ficoll 70/400 obtained at low ( hydropenic) vs raised ( normal) glomerular filtration rates (GFRs). The h for FITC-Ficoll was determined in anesthetized Wistar rat
A new type of supermacroporous, monolithic, cryogel affinity adsorbent was developed, allowing the specific capture of urokinase from conditioned media of human fibrosarcoma cell line HT1080. The affinity adsorbent was designed with the objective of using it as a capture column in an integrated perfusion/protein separation bioreactor setup. A comparative study between the utility of this novel cry
Mineral water and soft drinks with a perceptible off-odour were analysed to identify contaminants originating from previous misuse of the refillable polyethylene terephthalate ( PET) bottle. Consumers detected the off-odour after opening the bottle and duly returned it with the remaining content to the producers. The contaminants in question had thus been undetected by the in-line detection device
Injuries to the upper gastrointestinal tract occurring over a 30-year period in a geographically well defined region were analyzed. The incidence was low in comparison with other abdominal injuries, but duodenal and pancreatic injuries were increasingly common in the study's last decade. The stomach injuries were mainly caused by penetrating trauma. The duodenal and pancreatic injuries most common
Occlusive vascular disease is a widespread abnormality leading to lethal or debilitating outcomes such as myocardial infarction and stroke. It is part of atherosclerosis and is evoked by clinical procedures including angioplasty and grafting of saphenous vein in bypass surgery. A causative factor is the switch in smooth muscle cells to an invasive and proliferative mode, leading to neointimal hype
This thesis deals with the empirical testing of trade theories, traditionally used to analyze international trade, using regional data on production and trade. This thesis consists of three main essays. In the first essay, we analyze Swedish regional production. In the first part, we focus on the effects of comparative advantage in predicting regional manufacturing production. In so doing, we use
Under seeing limited conditions very high resolution spectroscopy becomes very difficult for extremely large telescopes (ELTs). Using adaptive optics (AO) the stellar image size decreases proportional with the telescope diameter. This makes the spectrograph optics and hence its resolution independent of the telescope diameter. However AO for use with ELTs at visible wavelengths require deformable
A terpyridine ligand has been covalently linked to a Ru(bpy)(3) complex via an amide bond. By using this functionalized terpyridine ligand, a series of multinuclear bimetallic complexes have been synthesized and characterized. One of these complexes has the structure of di-mu-oxobridged Mn dimer. EPR spectra of this complex showed that, depending on the procedure for the preparation, the oxidation
The role of the humoral immune response in herpes simplex encephalitis (HSE) is largely unknown. The finding that herpes simplex virus type 1 (HSV 1) induced IgG Fc receptor binds to all IgG subclasses except IgG 3 prompted an investigation of anti-HSV activity in IgG subclasses from serum and cerebrospinal fluid (CSF) in ten patients with proven or highly probable HSE by means of a monoclonal ant
We present the joint maximum likelihood (ML) symbol-time and carrier-frequency offset estimator in orthogonal frequency-division multiplexing (OFDM) systems. Redundant information contained within the cyclic prefix enables this estimation without additional pilots. Simulations show that the frequency estimator may be used in a tracking mode and the time estimator in an acquisition mode.
Various polymer electrolytes based on boronate esters and different lithium and sodium salts have been evaluated in electrochromic (EC) devices based on WO3 films. The results showed that the ionic conductivity of the electrolytes was not the most important parameter for the colouration performance of these devices. The use of solid electrolytes containing LiClO4 resulted in a higher colouration p
Chordoma is a rare, low- to intermediate-grade malignant tumor involving the axial spine. Cytogenetic data on these tumors have been limited to 25 cases. The findings of clonal chromosome aberrations in five new cases are presented. One of these and two previously reported cases have been studied with multicolor combined binary ratio labeling fluorescence in situ hybridization (COBRA-FISH). The ka
The basic helix-loop-helix (bHLH) transcription factor mammalian achaete-scute homolog-1 (MASH-1 in mouse and HASH-1 in human) is essential for proper development of olfactory and most peripheral autonomic neurons, and for the formation of distinct neuronal circuits within the central nervous system. We have previously shown that HASH-1 is expressed in neuroblastoma tumors and cell lines, and in t
Abstract in UndeterminedThis chapter will address both theoretical and methodological issues in pause analysis. First, the theoretical assumptions concerning how pause analysis can contribute towards our understanding of written language production are discussed. Subsequently, some measures, methods and tools for automatic pause analysis are presented and some empirical analyses are given. Most of
