Abstract

Mutated transthyretin-associated (ATTRm) amyloidosis with heart failure is associated with decreased longitudinal left ventricular (LV) myocardial contraction, as measured by strain Doppler echocardiography. We sought to clarify whether speckle-tracking echocardiography (STE) would [...]

Abstract

The diagnosis of thrombus in the left atrium in patients with persistent atrial fibrillation (AF) and may be inconsistent because of variability in thrombus morphology. In some cases it is challenging and requires unusual approach. New Doppler-derived methods might be helpful to identify [...]

Abstract

The research evaluates the behavior of a material when a plastic deformation occurs. The document describes the analytical process, finite elements and integrate process in order to develop shaped piece plan. Stress analysis and section variation were analyzed during the stuffing [...]

Abstract

Aiming at the safety problem of the pipeline containing corrosion defects caused by ground overload, a novel method is developed to assess the safety of buried pipelines with corrosion defects and predict the failure pressure. The effects of parameters including internal pressure, [...]

Abstract

This paper presents the main physical parameters, dependencies, calculation methods in the physical structural-energy theory of the strength of a deformed solid. The initial physical and mechanical parameters of the strength of steel 45 were determined analytically. The physical methods [...]

Abstract

Due to external interference, pipelines used for onshore as well as offshore operations can present dent and gouge defects. As such defects can seriously impair facilities’ integrity and performance, it is necessary to evaluate the strains in the vicinity of these defects. The development [...]

Abstract

The paper focuses on the long-term monitoring of the Milan Cathedral. After a concise historic background on the monument and the description of the sensing devices installed in the church, selected results obtained during the first year of static monitoring [...]
