BACKGROUND In normal ageing, both vascular and ventricular properties change, and how these affect left ventricular function is not clear. METHODS 96 subjects (ages 20-79) without cardiovascular disease underwent cardiac magnetic resonance (MR) imaging for measurement of global function, diastolic function (E/A ratio), MR tagging for measurement of torsion to shortening ratio (TSR, ratio of e...

The Thermographic Signal Reconstruction (TSR) technique, based on the logarithmic polynomial fitting of the temperature time-evolution, improves the efficiency of pulse-stimulated thermography. However, the non-destructive evaluation of the inspected structure requires the analysis of the full temperature-time sequence. This drawback impacts all transient thermal NDE method whatsoever. A new po...

Background: Factors such as tumour-stroma ratio (TSR) and peritumoral inflammation have been found to be reliable independent prognostic factors in some solid tumours. The aim of this preliminary study was to assess the relationship between these factors and the predicted prognosis based on the grade of the tumour in colorectal cancer (CRC). Methods: Medical and pathological records of patients...

In 1976, Kaplansky introduced the class JB∗-algebras which includes all C∗-algebras as a proper subclass. The notion of topological stable rank 1 for C∗-algebras was originally introduced by M. A. Rieffel and was extensively studied by various authors. In this paper, we extend this notion to general JB∗-algebras. We show that the complex spin factors are of tsr 1 providing an example of special...

The purpose of this paper is to investigate the effects Corporate Sustainability (CS; actual practices and reporting) on total shareholder returns (TSR). We also subcomponents Sustainability, i.e., environmental, social, governance practices. use fixed regression models relationship between TSR using 944 firm-year observations in Nordic stock markets. proxy sustainability reporting through Bloo...

This study presents the results of an experimental campaign aimed at testing effectiveness carbon fiber reinforced cementitious matrix (CFRCM) confinement as a repair technique for severely damaged concrete (RC) columns. To evaluate shape effect and transverse steel reinforcement (TSR) – interaction, two different cross-section shapes, TSR rates were investigated. Nine full-scale specimens anal...

Potensi sumber daya energi terbarukan di Indonesia sangat besar. tersebut dapat dimanfaatkan untuk mendistribusikan secara merata. Salah satu pemanfaatannya yaitu dengan menggunakan turbin angin Darrieus mengubah menjadi listrik. Berbagai upaya telah dilakukan guna meningkatkan kinerja turbin. Penelitian ini studi numeric memvariasikan tinggi fin mengetahui nilai Cp, Ct dan TSR. Metode Computat...

Chemotactic signaling in Escherichia coli involves transmission of both negative and positive signals. In order to examine mechanisms of signal processing, behavioral responses to dual inputs have been measured by using photoactivable "caged" compounds, computer video analysis, and chemoreceptor deletion mutants. Signaling from Tar and Tsr, two receptors that sense amino acids and pH, was studi...

Heparin-binding growth-associated molecule (HB-GAM) is an extracellular matrix-associated protein implicated in the development and plasticity of neuronal connections of brain. Binding to cell surface heparan sulfate is indispensable for the biological activity of HB-GAM. In the present paper we have studied the structure of recombinant HB-GAM using heteronuclear NMR. These studies show that HB...

When a hydrokinetic turbine operates in confined flow, blockage effects are introduced, altering the flow at and downstream of rotor. Blockage have significant effect on loading performance turbines. As result, understanding them is critical for design prediction. The current study examines main interaction solidity (σ), tip speed ratio (TSR), (ε), pitch angle (θ) how influences (CP) three-blad...
