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

This article deals with the limits of divine power in the Old Testament. The aim is to show how one of the traditional attributes from ancient philosophical metaphysics, namely, omnipotence, does not fit the depiction of YHWH in the Hebrew Bible. The biblical traditions know of several limitations of divine power that must be reconciled to regional and functional limits, and the one must difficult

Flow cytometric assessments of DNA ploidy status and the S-phase fraction (SPF) have been shown to yield prognostic information in breast cancer. The aim of the present investigation was to elucidate the reproducibility of results with regard to tumor DNA heterogeneity, and to ascertain whether the prognostic value of DNA measurements might be enhanced by analyzing two pieces of a tumor instead of

This is a grounded theory study to identify concepts for describing how adolescents with inflammatory bowel disease (IBD) respond to their parents' concern for them. Ten adolescent boys and seven girls were interviewed. In the analysis four main categories emerged: ambivalence, ability/inability, compliance/resistance and trust/distrust. We found ambivalence to be the most distinctive theme to app

The need to reduce CO₂ emissions from fossil-fuel based power production creates the need for new power plant solutions where the CO ₂ is captured and stored or reused. Oxygen Transfer Membrane (OTM) is the key component of oxy-fuel combustion processes as pure oxygen is usually required to process reactions (e.g. Natural Gas Combined cycle NGCC, Pulverised Coal-fired power p

The Oxford-12 Item Knee Score is a recently developed and validated patient-completed outcome measure designed specifically for use with knee arthroplasty in the United Kingdom. We have translated this questionnaire into Swedish and tested the validity and reliability of the translated version in a cross-sectional study by a postal survey to 1,200 randomly selected patients from the Swedish Knee A

Coronary artery disease (CAD) is a condition in which the blood supply to the myocardium is partially or completely blocked due to plaque build-up in the artery wall. Myocardial SPECT imaging is a commonly used technique to assess the blood flow to the myocardium and the function of the heart. The interpretation of the images can be difficult and subjective. Several automatic myocardial SPECT quan

Iterative numerical schemes for solving the electrostatic partial differential equation with variable conductivity, using fast and high-order accurate direct methods for preconditioning, are compared. Two integral method schemes of this type, based on previously suggested splittings of the equation, are proposed, analyzed, and implemented. The schemes are tested for large problems on a square. Par
