Cross sections for elastic production of J/psi mesons in photoproduction and electroproduction are measured in electron proton collisions at HERA using an integrated luminosity of 55 pb(-1). Results are presented for photon virtualities Q(2) up to 80 GeV2. The dependence on the photon-proton centre of mass energy W-gamma p is analysed in the range 40 <= W-gamma p <= 305 GeV in photoproduction and
The purpose of this study was to investigate the prognostic implications of BCL6 rearrangement in a uniformly treated population of patients with diffuse large B-cell lymphoma (DLBCL) and to characterise the relationship between BCL6 rearrangement and prognostic factors. A total of 269 patients with DLBCL entered a randomised trial comparing the chemotherapy regimen CHOP (cyclophosphamide, doxorub
This overview focusses on the ubiquitous presence of immunohistochemically visible peptidergic nerves with vasodilatory function. The nerve fibres are primarily related to the parasympathetic system (vasoactive intestinal polypeptide or VIP), the sympathetic system including the adrenal medulla (enkephalins) and to the sensory system (substance P as well as calcitonin gene-related peptide, CGRP).
The creation spectra of F centres by synchrotron radiation of 5-35 eV have been measured for Na6Al6Si6O24(NaI)(2x) and Na6Al6Si6O24(NaBr)(2x) optical ceramics at 8 and 80 K. The exciting photons cause the excitation and ionization of halogen ions (6-8 eV) and of an aluminosilicate carcass (8.5-31 eV) or the excitation of Na+ ions (32-35 eV). An exciting photon of 20-26 and 27-31 eV creates two or
A theoretical model has been developed for the drop behaviour in siphon riser tubes in paper drying cylinders. Analytical solutions to the equations are presented for the systems air-water at atmospheric pressure and saturated steam-water. Numerical simulations are performed for a large number of input data. Calculated drop trajectories indicate that the drops travel only a small part of the riser
Nationellt kompetenscentrum för rörelseorganens sjukdomar (NKO) är ett resurscentrum för kvalitetsregister inom rörelseorganens sjukdomar. En förutsättning för en mer rättvis vård är att indikationerna för behandling betraktas likartat över hela landet. Evidensbaserade indikationer för behandling av rörelseorganens sjukdomar har utarbetats. Klargörande av aktuell indikationssättning för höft- och Well-functioning data registration systems require high competence both in the technical systems used for handling data and in the statistical methodology used for analysis. Consequently, The Swedish Association of Local Authorities and Regions and The National Board of Health and Welfare started the Swedish National Competence Centre for Musculoskeletal disorders, with the purpose for this instit
Linkage analysis of F-2 crosses has led to identification of large numbers of quantitative trait loci (QTL) for complex diseases, but identification of the underlying genes has been more difficult. Reasons for this could be complications that arise from separation of interacting or neighboring loci. We made a partial advanced intercross (PAI) to characterize and fine-map linkage to collagen-induce
This paper reports on a test of the validity of Pienemann's (1998) Processability Theory (PT). This theory predicts that certain morphological and syntactic phenomena are acquired in a fixed sequence. Three phenomena were chosen for this study: attributive adjective morphology, predicative adjective morphology, and subordinate clause syntax (placement of negation). These phenomena are located at s
We have developed a new reactive force field, ReaxFF, for use in molecular dynamics (MD) simulations to investigate the structures and reactive dynamics of complex metal oxide catalysts. The parameters in ReaxFF are derived directly from QM and have been validated to provide reasonable accuracy for a wide variety of reactions. We report the use of ReaxFF to study the activation and conversion of p
The PIXE technique offers the possibility of scanning a single hair strand longitudinally with a millimetre proton beam for trace elements. However, the accuracy of the method has been questioned since the quantification of the mass concentration has been a serious problem. In this paper a specific beam-hair-detector geometry is assumed, and the correction factor accounting for the proton energy l
Aim: To investigate the association between the use of cellular or cordless telephones and the risk for salivary gland tumours. Methods: Cases were assessed from the six regional cancer registries in Sweden. Four controls matched for sex and age in five year age groups were selected for each case. A total of 293 living cases and 1172 controls were included. Results: There were 267 (91%) participat
BACKGROUND AND PURPOSE: The purpose of this study was to determine whether preoperative and postoperative enrichment of the environment can enhance the functional outcome after cerebral infarction in rats. METHODS: The right middle cerebral artery was ligated in adult spontaneously hypertensive male rats, and the functional outcome was studied for 12 weeks after the operation. Three groups were co
The entity sinusitis, bronchiectasis, and situs inversus is since long named Kartagener syndrome. Nowadays the designation used is primary ciliary dyskinesia (PCD), which implies cilia with decreased or total absence of motility, which may result in sinusitis, chronic bronchitis, bronchiectasis, and male infertility. A large number of deficiencies detectable on the ultrastructural level give rise
Eleonora's Falcon (Falco eleonorae) breeds in the Mediterranean region and is highly adapted for catching small birds on passage migration between Eurasia and their African winter quarters, which they feed their young. We studied gliding flight behavior of Eleonora's Falcon at a breeding colony located on a small island southwest of Sardinia, Italy. Gliding and soaring flight performance was measu
The study of quark jets in e(+)e(-) reactions at LEP has demonstrated that the hadronisation process is reproduced well by the Lund string model. However. our understanding of gluon fragmentation is less complete. In this study enriched quark and gluon jet samples of different purities are selected in three-jet events from hadronic decays of the Z collected by the DELPHI experiment in the LEP runs
Prostate specific antigen (PSA) in serum has recently been shown to occur in complex with alpha 1-antichymotrypsin and as an approximately 30 kDa. noncomplexed molecular form. We characterized PSA by 3 different assays in samples from 144 patients with benign prostatic hyperplasia (BPH) and 121 with carcinoma of the prostate. One of these noncompetitive assays measured total PSA by detecting PSA c
