This contribution presents a sample preparation methodology to enable the identification, with synchrotron radiation-based analytical techniques, of the gettering sites of metallic impurities on the internal walls of implantation-induced nanocavities in Si substrates. Preliminary results for the Cu-Si and Cu-Cu bond lengths on the internal surface of the nanocavities are reported. (C) 2002 Elsevie

Over a period of three years, at least three different males of Common Redstarts Phoenicurus phoenicurus in southern Sweden mimicked the song of Scarlet Rosefinch Carpodacus erythrinus. At least two of the Redstarts were second calendar year birds that were heard to mimic Rosefinch song in spring long before the arrival of the local breeding population of Scarlet Rosefinch. Since Redstarts and Ros

Squid cranial cartilage has been found to contain three different proteoglycan populations, two of which form aggregates (Vynios, D.H. and Tsiganos, C. P., Biochim. Biophys. Acta 1033: 139-147, 1990). The aggregation involves interaction of their protein cores as assessed by electron microscopy and biochemical data. Aggregating oligopeptides were isolated after mild trypsin digestion which inhibit

Although the Mongolic language group consists of ten rather closely related languages, there is no consensus in the literature about the classification of the languages into subgroups. One reason for this is the occurrence of more or less independent phonological innovations which are difficult to order in time and which may have spread geographically rather than genetically. All Mongolic language

During the last years, three rarely collected Lecidea species have been found in Skane and Halland, southernmost Sweden, viz. "Lecidea" ahlesii, L. promixta and L. confluentula. The first two are reported earlier from Sweden, but are probably overlooked. L. confluentula is new to Sweden, has been confused with L. fuscoatra, and shown here to be fairly common in western Sweden. All species are depi

This thesis presents results from two areas of research. Firstly, the resonant coherent laser techniques polarization spectroscopy (PS), degenerate four-wave mixing (DFWM) and stimulated emission (SE) have been developed in the general field of combustion diagnostics. Secondly, laser induced fluorescence (LIF) has been developed and applied for the visualization of mixture fractions in turbulent n

Background. Dehiscence of colon anastomosis is a common, serious and potentially life-threatening complication after colorectal operation. In experimental models, impaired biomechanic strength of colon anastomoses is preventable by general inhibitors of matrix metalloproteinases (MMPs) and associated with collagen loss, which indicates a possible link between MMP-mediated collagen degradation and

X-rays from a laser-produced plasma were analysed using single-photon counting germanium detectors. Special attention was given to the extremely high photon flux, requiring either a long source-detector distance and narrow collimated measurement geometry in order to avoid severe pile-up of pulses in the spectrometer, or the use of a Compton scattering geometry. With the use of these techniques, in

The aim of the present study was to analyse quantitatively, on a cat gastrocnemius muscle preparation in vivo, the effects of local angiotensin-converting enzyme (ACE) inhibition by enalaprilat on total regional vascular resistance (tone) and its distribution to the large-bore arterial resistance vessels (> 25 microns), the small arterioles (< 25 microns) and the veins. Associated effects on capil

Trisomy 8 as the sole abnormality is the most common karyotypic finding in acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS), occurring in approximately 5% and 10% of the cytogenetically abnormal cases, respectively. However, despite the high frequency of +8, much remains to be elucidated as regards its epidemiology, etiology, clinical impact, association with other chromosomal abno

The various granule subtypes of the human neutrophil differ in propensity for exocytosis. As a rule, granules formed at late stages of myelopoiesis have a higher secretory potential than granules formed in more immature myeloid cells. Neutrophils contain four closely related alpha-defensins, which are stored in a subset of azurophil granules. These defensin-rich azurophil granules (DRG) are formed

Popular Abstract in Swedish Inom hälso- och sjukvården betonas att vården ska ges utifrån ett patientorienterat sätt. Om sjuksköterskor skall kunna ge patienten god omvårdnad, måste de själva ha en god arbetssituation. Det blir allt vanligare att sjuksköterskor i arbetet utsätts för en mängd negativa psykiska påfrestningar, såsom hot och våld, som kan leda till stress. Stress kan också relateras tThe purpose of group supervision in nursing care is to understand nurses’ experiences from real care settings and to structure these in a professional and personal context. An interventional and longitudinal method of research was chosen in this study of group supervision in nursing care. The overall aim of the present study was to examine and investigate how psychiatric nurses’ professional compe

In this work we discuss different factors governing coil-globule coexistence in the compaction process of DNA. We initially analyse the role played by fluctuations in the degree of binding of an external compacting agent in the conformational behavior of the chain backbone. The analysis relies both on Monte Carlo simulation results and simple statistical approaches. Compacting agents of various bi

The spin-state of cytochrome b559 (Cyt b559) was studied in photosystem II (PSII) membrane fragments by low-temperature EPR spectroscopy. Treatment of the membranes with 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) converts the native low-spin (LS) form of Cyt b559 to the high-spin (HS) form characterized with the g= 6.19 and g= 5.95 split signal. The HS Cyt b559 was pH dependent with the amplitu

Bioelectrocatalytic oxidation of theophylline was studied at gold and graphite electrodes modified with microbial theophylline oxidase (ThOx), a multi-cofactor redox enzyme capable of selective oxidation of theophylline. Gold electrodes were additionally modified with self-assembled monolayers (SAMs) of (-OH)- and (-NH2)-terminated alkanethiols of different chain lengths, to achieve compatibility

It is of central interest in membrane proteomics to establish methods that combine efficient solubilization with enrichment of proteins and intact protein complexes. We have investigated the quantitative and qualitative solubilization efficiency of five commercially available detergents using mitochondria from the yeast Saccharomyces cerevisiae as model system. Combining the zwitterionic detergent
