Non-radiative decay of core excitations at the B 1s and N 1s absorption edges of bulk hexagonal boron nitride (h-BN) has been studied with resonant Auger spectroscopy. In order to reproduce the bulk properties of the sample while keeping it electrically conducting, we have grown reasonably thick (more than 20nm) polycrystalline films of h-BN on a Ni(111) surface by thermal cracking of borazine vap

Popular Abstract in Swedish Den sedimentära lagerföljd som bygger upp Gotland avlagrades för drygt 400 miljoner år sedan (under silurperioden) i ett varmt tropiskt innanhav strax söder om ekvatorn. Innanhavet sträckte sig som en vid bukt in över dagens södra Skandinavien, Baltikum och vidare mot sydost, till Ukraina. Avhandlingen behandlar primärt hur sedimentationsmönster utvecklades under cirka The Silurian foreland of Scandinavia included a vast epicontinental carbonate platform system of which the island of Gotland (Sweden) is an erosional remnant. This thesis treats the Late Wenlock succession (Cyrtograptus lundgreni, Pristiograptus dubius parvus, Gothograptus nassa, Colonograptus(?) praedeubeli, and the Co(?) deubeli zones), and emphasises the sedimentology and biostratigraphy of the

High spin states in the nucleus Tc-91 have been studied via the fusion evaporation reaction Ni-58(Ar-36,3p)Tc-91, at 149 MeV and 140 MeV beam energy. The OSWS spectrometer, an additional high purity Ge detector at 162 degrees, and several particle detectors were used to measure gamma gamma- and particle-gamma coincidences, directional correlations of oriented states, and line shapes due to Doppler

The title compound, [ RhCl( PBz(3))(2)( CO)] [ PBz(3) = tribenzylphosphine, P(C7H7)(3)], which is the first reported tribenzylphosphine - rhodium( I) structure, has pseudo- square- planar coordination geometry, with Rh - P bond distances of 2.3164 ( 15) and 2.3156 ( 16) Angstrom. The Rh - Cl, Rh - C and C - O bond distances are 2.3654 ( 15), 1.783 ( 6) and 1.162 ( 6) Angstrom, respectively, and th

Significance of eco-friendly materials based on easily renewable natural resources, and the finite nature of petrochemical resources, has necessitated the development of polymers from agricultural processing by products such as soy proteins from oil processing. Although, considerable work was done in the early part of last century on polymers based on soy protein, there was almost no activity in t

Breast ducts contain two types of epithelial cells, inner luminal cells and outer basal/ myoepithelial cells. These cells can be distinguished by their immunophenotype. Cytokeratins ( CKs) 8 and 18 are expressed in the luminal layer, whereas CK5/ 14 and the transcription factor p63 characterize the basal epithelial layer. We studied a population- based cohort of 288 sporadic ductal invasive cancer

Information on the effects of thyroid hormone on smooth muscle contractile protein expression and mechanical properties is sparse. We have addressed the following questions. (1) Can thyroxine hormone alter myosin isoform composition in smooth muscle? (2) Can a change in myosin isoform composition lead to altered mechanical properties in smooth muscle? (3) Are alterations, if occurring, equal in fa

Trilobites from the Middle and Upper Ordovician Andersön Shale Formation in Jämtland, central Sweden, and the Middle Ordovician Killeröd Formation in Skåne (Scania), southern Sweden, are revised and discussed. These formations have several genera and a few species in common, e.g. Botrioides efflorescens (Hadding, 1913a) and Pseudomegalaspis patagiata (Törnquist, 1884). The regional and vertical di

A group of Swedish oncologists and hospital physicists have estimated the number of patients in Sweden suitable for proton beam therapy. The estimations have been based on current statistics of tumour incidence, number of patients potentially eligible for radiation treatment, scientific support from clinical trials and model dose planning studies and knowledge of the dose-response relations of dif

Blood group ABO polymorphism was analysed in genomic DNA isolated from 150 blood donors by restriction endonuclease digestion of three polymerase chain reaction-amplified exons in the ABO genes and by sequencing of randomly selected samples. An anomalous O1 allele first described in a cancer cell line is now shown to account for approximately 40% of the O alleles described to date. This is 10 time

Popular Abstract in Swedish Reformationens budskap brukar karakteriseras med hjälp av några "allena": Kristus allena, tron allena, nåden allena och Skriften allena. I denna studie undersöks hur Martin Chemnitz (1522-86) behandlar dessa teman och hur han sätter dem i relation till Augustinus teologi. Martin Chemnitz var en av de mest framstående evangeliska teologerna i generationen efter Martin LuAs a co-author of the Formula of Concord, Martin Chemnitz (1522-86) codified the sola scriptura principle of the Reformation, that the prophetic and apostolic Scriptures are the only rule for all Church doctrine. This principle is clearly expressed in Chemnitz' own theological treatises as well, but in his argumentation one is also confronted with an astonishing number of quotations from the Churc

Popular Abstract in Swedish Avhandlingen undersöker naturumgängets modernisering i Förenade Arabemiraten, en federation av sju shejkdömen på den arabiska sidan av Persiska Viken. De traditionella näringarna var handel, pastoralism, fiske och pärlfiske, men dessa har sedan 1960-talet ersatts av en ekonomi baserad på export av fossila bränslen. Landet har under kort tid övergått från att vara ett trThe thesis investigates human-environmental relations in the rapidly modernizing United Arab Emirates, a federation of seven Arabian Gulf sheikhdoms. Since its establishment in 1971, the UAE has been transformed from a subsistence society based mainly on pastoralism and maritime activities (fishing, pearling, and trade) into an ultramodern society, with an economy based on the export of fossil fue

An affinity-assay was developed that is based on the modulation of the diffusion coefficient of a redox-labelled hapten upon complementary recognition of the analyte leading to an increase of molecular weight and hence to a decrease of the diffusion coefficient. The slower diffusion is monitored by means of cyclic voltammetry. In order to demonstrate the feasibility of this assay format, recogniti

Antibiotics constitute the dominant treatment of gastrointestinal infections. However, several serious side-effects are associated with extensive use of antibiotics, including spread of bacterial resistance and allergic reactions as well as potential overgrowth of pathogenic bacteria and viruses. On the other hand, there is a growing body of evidence suggesting that certain bacteria, referred to a
