The atomic and electronic structure of the lattice-mismatched h-BN/Pt(111) and h-BN/Rh(111) interfaces formed by pyrolitic reactions with vaporized borazine has been studied by low-energy electron diffraction, scanning tunneling microscopy, x-ray-absorption spectroscopy, and core-level and valence-band photoemission. It has been found that on Pt(111), h-BN forms a nearly flat monolayer, insignific
This paper presents a methodological approach for the study of volatile organic compounds (VOCs) in air, emitted during storage of municipal solid waste in bales. Determination of VOCs was based on sampling with adsorbent tubes followed by automated analysis using on-line work-up with a thermal desorption unit directly connected to a gas chromatograph-mass spectrometer. Using calculation algorithm
Thionation reactions of several bisindole derivatives using elemental sulfur or P4S10 in pyridine have been studied, leading to formation of several novel structures. The reaction of indigo or isatin with P4S10 gave the structurally new salt 10, which could be transformed into the ethyl derivative 11. The first example of a thionated indigo derivative, monothioindigo (6), was isolated in low yield
On film critic Robin Wood's views on horror movies.
DELPHI data collected at centre-of-mass energies up to 208 GeV have been analysed to search for charginos, neutralinos and sfermions in the framework of the Minimal Supersymmetric Standard Model (MSSM) with R-parity conservation. No evidence for a signal was found in any of the channels. The results of each search were used to derive limits on production cross-sections and particle masses. In addi
In the thesis, that has its basis in my educational work at Malmö Theatre Academy, I discuss how actors in training solve the problem of embodying the role ? how they, from their ideas, feelings, thoughts and knowledge create the physical actions of the role. My discussion has its basis in how the training in acrobatics can form a sort of model for the strategies needed by the actor to perform on
Three novel tetracyclic terpenoids, of which two possess potent cytotoxic activities towards various mammalian cell lines, were isolated front extracts of the fermentation broth of the ascomycete Dasayscyphus niveus. The structures of the compounds, named dasyscyphins A-C, were determined with spectroscopic techniques. (c) 2005 Elsevier Ltd. All rights reserved.
This article focuses on bone cement, the cementing technique used, and their influence on aseptic loosening and infection of acrylic and joint implants in Scandinavia.
Gamma ray spectroscopy of neutron deficient nuclei close to the doubly magic nucleus Sn-100 has been performed using a heavy-ion reaction and the NORDBALL Ge-detector array. Evaporation residues were identified by means of charged particle and neutron detection. Transitions in 31 different evaporation residues were identified. New results on Cd-102 are presented.
This paper presents a microcalorimetric technique to simultaneously measure water activity and enthalpy of mixing (differential heat of sorption) as functions of composition at high water activities. The instrument consists of a sorption vessel in a double twin microcalorimeter. A sample at high water activity is placed in one chamber of the vessel and an unsaturated salt solution is injected into
SelB is a bacterial elongation factor required for the decoding of a UGA stop codon together with a specific mRNA hairpin to selenocysteine. In attempts to crystallize Moorella thermoacetica SelB, a proteolysis process occurred and crystals of a proteolytic fragment were observed. The crystals, which appeared after a year, contained a C-terminal 30 kDa fragment containing the mRNA-binding domain.
Bruton's tyrosine kinase (Btk) is a nonreceptor tyrosine kinase, critical for B-cell development and function. Mutations that inactivate this kinase were found in families with X-linked agammaglobulinaemia (XLA). In this study the Btk gene was analyzed in 13 registered Greek patients with XLA phenotype originated from 12 unrelated families, in order to provide a definite diagnosis of the XLA. The
On the origin, use and dating of the customary of the cathedral chapter of Lund, i.e. the Consuetudines Lundenses. I have argued that the consuetudines were used by the canons from 30 June 1123 at the latest, the day of inauguration of the crypt church. This seems even more plausible as the prototype of the text, i.e. the Consuetudines Marbacenses, were recently antedated. Furthermore, these circu
