An exact description of the interactions in aromatic carbon systems is a key condition for the design of carbon based nanomaterials. In this paper we investigate the binding and adsorbate structure of the simplest prototype system in this class the single aromatic ring molecule benzene on graphite. We have collected neutron diffraction data of the ordered phase of deuterated benzene, C6D6, adsorbe

The deposition of TiOx (x <= 2) structures on Au(111) by chemical vapor deposition (CVD) in ultrahigh vacuum (UHV) has been investigated with high-resolution core level photoelectron spectroscopy (PES), low-energy electron diffraction (LEED) and scanning tunneling microscopy (STM). Using titanium tetra-isopropoxide as single source precursor it is possible to form different TiOx phases on the surf

We present a consistent way of combining associated weak boson radiation in hard dijet events with hard QCD radiation in Drell-Yan-like scatterings. This integrates multiple tree-level calculations with vastly different cross sections, QCD- and electroweak parton-shower resummation into a single framework. The new merging strategy is implemented in the PYTHIA event generator and predictions are co

Infection with the Gram-negative pathogen Prevotella intermedia gives rise to periodontitis and a growing number of studies implies an association of P. intermedia with rheumatoid arthritis. The serine protease Factor I (FI) is the central inhibitor of complement degrading complement components C3b and C4b in the presence of cofactors such as C4b-binding protein (C4BP) and Factor H (FH). Yet, the

There is limited evidence on the association between dietary folate intake and the risk of breast cancer (BC) by hormone receptor expression in the tumors. We investigated the relationship between dietary folate and BC risk using data from the European Prospective Investigation into Cancer and Nutrition (EPIC). A total of 367993 women age 35 to 70 years were recruited in 10 European countries. Dur

Pyramidal metamaterials are currently developed for ultra-broadband absorbers. They consist of periodic arrays of alternating metal/dielectric layers forming truncated square-based pyramids. The metallic layers of increasing lengths play the role of vertically and, to a less extent, laterally coupled plasmonic resonators. Based on detailed numerical simulations, we demonstrate that plasmon hybridi

I biogassektorn finns ett ökande behov av och en ökande konkurrens om råvaror, och intresset för användning av odlingsrester, vall, mellangrödor mm som biogasråvara ökar. Gemensamt för dessa råvaror är att de är fiberrika, dvs. har ett högt innehåll av lignocellulosa, vilket gör att det är osannolikt att de skulle användas för biogasproduktion utan förbehandling. Ett antal förbehandlingstekniker h

Radioimmunotherapy (RIT) is a therapeutic strategy in which radionuclides are conjugated to monoclonal antibodies that bind to tumor-associated antigens in the tumor, so that the decay of the radionuclide takes place inside the tumor. The aim of the research presented in this thesis was to investigate the effects of RIT (utilizing the radioconjugated antibody 177Lu-BR96) on an inoculated tumor and

OBJECTIVE: To assess the outcome of vacuum-assisted wound closure (VAC(®)) therapy for infected bypass grafts. METHODS: A retrospective 7-year review of patient records from 2004 to 2011 of all patients receiving VAC(®) therapy for infected bypass grafts. RESULTS: Thirty-seven patients with 42 wounds and 45 infected bypass (28 synthetic) grafts received VAC(®) treatment. Two serious bleeding e

In a rabbit model, we have previously reported evidence for a pathogenic role of streptococcal IgG Fc-binding proteins (IgGFcBP) in poststreptococcal glomerulonephritis (PSGN). These proteins, of the M protein family, were shown to trigger anti-IgG production and enhance renal deposition of IgG and/or immune complexes (ICs), with resulting activation of complement and cytokine cascades. In the pre

During the last 35 years almost 5000 ceramic thin-sections have been analysed at the Laboratory for Ceramic Research, Lund University and of those have 1650 analyses been performed on material from the Iron Age in Northern Europe (here c. 500 BC-1100 AD). Currently there is a project to register these analyses in a database and evaluate the results. We can for the first time get an overall picture

While the etiology of multiple myeloma (MM) is largely unknown, evidence for an inherited genetic susceptibility is provided by the two-fold increased risk of the disease seen in first-degree relatives of cases of MM. It is likely that part of this heritable risk is a consequence of the co-inheritance of low-risk genetic variants. The accumulated experience to date in identifying risk variants for

Historically, organizations developed their information systems in-house. Today, a large portion of information systems development is based on the acquisition of pre-made information systems, so-called commercially off-the-shelf (COTS) systems. This approach for developing information systems requires new skills and methods supporting the process of evaluating and selecting information systems. T

Over the last years an expanding family of small non-coding RNAs (sRNA) has been identified in eukaryotic genomes which behave as sequence-specific triggers for mRNA degradation, translation repression, heterochromatin formation and genome stability. To achieve their effectors functions, sRNAs associate with members of the Argonaute protein family. Argonaute proteins are segregated into three para
