A direct search has been made for magnetic monopoles produced in e(+)p collisions at a centre of mass energy of 300 GeV at HERA. The beam pipe surrounding the interaction region in 1995-1997 was investigated using a SQUID magnetometer to look for stopped magnetic monopoles. During this time an integrated luminosity of 62 pb(-1) was delivered. No magnetic monopoles were observed and charge and mass
Screening women for lower genital tract infection with Chlamydia trachomatis is important in the prevention of pelvic inflammatory disease, ectopic pregnancy and infertility. This systematic review aims to state clearly which of the available diagnostic tests for the detection of C. trachomatis would be most effective in terms of clinical effectiveness. The review included all studies published fr
PURPOSE: A spin-echo diffusion-sensitized pulse sequence using high gradients (23 mT/m) is introduced. MATERIAL AND METHODS: In order to minimize motion artefacts, velocity-compensating gradients, ECG-triggering and post-processing with phase correction and raw data averaging using navigator echoes was performed. The in vitro ratio of diffusion coefficients for water and acetone was determined and
As part of a project aimed at developing models for photosystem II (PSII) in green plants, we have prepared a series of model compounds (7, 8, and 13). In these compounds, a photosensitizer, ruthenium(II) tris(bipyridyl) complex (to mimic the function of P-680 in PSII), was covalently linked to a manganese(II) ion through different bridging ligands. The structures of the compounds were characteriz
Most of the world's energy generation is based on fossil fuels such as coal and oil, which already today but even more in the future, will cause various problems. One issue is their limited availability, which stands in conflict to the increasing global energy consumption. Another problem is the carbon dioxide generation caused by burning fossil fuels for energy production, and is thought to be on
This paper describes a methodology for measuring theological flow properties in-line, in real-time, based on simultaneous measurements of velocity profiles using an ultrasound velocity profiling (UVP) technique with pressure difference (PD) technology. The methodology allows measurements that are rapid, non-destructive and non-invasive and has several advantages over methods presented previously.
OBJECTIVE: Free radicals formed after coronary artery occlusion and reperfusion are assumed to produce myocardial stunning and possibly other forms of reperfusion injury as well. Malondialdehyde (MDA) is an end product in the lipid peroxidation chain reaction and is frequently used as a marker for free oxygen radical production. Increased levels of plasma MDA have been found following successful t
We have previously described the evaluation of a cDNA microarray platform to identify and clone mutated barley (Hordeum vulgare L.) genes, using their transcriptionally defective mutant alleles (S. Zakhrabekova, C.G. Karmangara, D. von Wettstein, M. Hansson, A microarray approach for identification of mutated genes, Plant Physiol. Biochem. 40 (2002) 189-197). It was concluded that competitive hybr
Small bowel carcinoid tumor (SBC) is a rare disease of unknown etiology bill with all age-, sex-, and place-specific occurrence that may indicate an occupational origin. A European multicenter population-based case-control study was conducted from 1995 through 1997. Incident SBC cases between 35 and 69 years of age (n = 101) were identified, together with 3335 controls sampled from the catchment a
I södra sjukvårdsregionen har ett arbete inletts för att kontinuerligt genomföra sakkunniga granskningar (sk peer review) av traumasjukvården inom regionen. I en första granskningsomgång har sex akutsjukhus deltagit. Resultaten har sammanställts i ett granskningsdokument, som gett upphov till såväl uppmärksamhet och diskussion som konkreta åtgärder på det granskade sjukhuset. Granskningsdokument
Dynamic susceptibility-contrast (DSC) MRI requires deconvolution to retrieve the tissue residue function R(t) and the cerebral blood flow (CBF). In this study, deconvolution of time-series data was performed by wavelet-transform-based denoising combined with the Fourier transform (FT). Traditional FT-based deconvolution of noisy data requires frequency-domain filtering, often leading to excessive
The use of test coverage measures (e.g., block coverage) to control the software test process has become an increasingly common practice. This is justified by the assumption that higher test coverage helps achieve higher defect coverage and therefore improves software quality. In practice, data often shows that defect coverage and test coverage grow over time, as additional testing is performed. H
We examine the near-field optical properties of multilayered metal core-shell sphere nanostructures by extending the Mie theory, and demonstrate that the local-field enhancement can be increased by adding new metal shells. A local intensity enhancement of more than 10(5) times can be obtained in the cavity between the Ag core and the innermost Ag shell for proper configurations of multilayered Ag
We evaluated 2 consecutive cohorts of patients with primary trapeziometacarpal arthrosis 1 year after either first metacarpal osteotomy or trapezial excision with abductor pollicis longus tendon arthroplasty. At follow-up, 4 of 7 patients treated with osteotomy had pain at rest and/or with light activities and were dissatisfied with the results of surgery, all 4 had advanced (stage III) preoperati
The use of Intelligent control schemes in Nonlinear Model Based Control (NMBC) has gained widespread popularity. Neural Networks, in particular, have been used extensively to model the dynamics of nonlinear plants. However, in most cases, these models do not lend themselves to easy maneuvering for controller design. Therefore, a common need is being felt to develop intelligent control strategies t
In this Licentiate Dissertation presents a new model for selecting environmental performance indicators in order to improve environmental management. The suggested Total Cost Indicators support a support a preventive approach to environmental management, where environmental issues are addressed before they arise - and before they become costs. The method of selecting indicators builds on earlie
Vehicles in the future are anticipated to have the ability to communicate and exchange useful information in order to avoid collisions. However, for this cooperation to be possible all vehicles will have to be equipped with compatible wireless IEEE 802.11p modules that implement intelligent transport systems operating in the 5 GHz frequency band standard (ITS-G5 or WAVE). During the implementation
