Fibre reinforced concretes (FRCs) are composite materials now largely adopted in structural applications given their mechanical properties terms of the residual tensile strength, almost absent for plain concrete. The short-term behaviour these material has been deeply studied, while time-dependent deformations have received less attention from scientific community. present paper presents experi...

  In this paper the numerical analysis of flow and time dependent heat transfer of micro-tube conveying nanofluid in laminar flow is investigated. In this study, convection heat transfer of nanofluid and base fluid and transient analysis for time-varying heat flux for time step of 0.0001 second are elucidated. It is observed that the pumping power of nanofluid flowing and the maximum temperatur...

background and objectives: scapular stabilization and neuromuscular control provide an important parameter to characterize shoulder function during dynamic activities. many studies have confirmed the effect of the loading on scapular position and scapulohumeral rhythm. therefore, the evaluation of stabilizer muscles involvement in scapular asymmetry may assist in the development of clinical exa...

We examined the temporal kinetics of onset and offset of the cardiac electrophysiologic effects of orally administered amiodarone in chronically instrumented, unsedated adult dogs (n = 8). Right atrial (RA), atrioventricular nodal (AVN), and right ventricular (RV) effective refractory period (ERP), and AVN functional refractory period (FRP), were determined daily for 21 days during amiodarone l...

Wax deposition phenomenon changes the rheological behavior of waxy crude oil completely. In the current work, the rheological time-dependent and time-independent behaviors of waxy crude oil samples are studied and flow curve and compliance function are measured for the oil samples with various wax contents at different temperatures. A decrease in temperature and an increase in wax content lead ...

This study analyzes the free vibration, forced vibration, resonance, and stress wave propagation of orthotropic sandwich plates made of functionally graded materials (FGMs). Dynamic analyses are conducted using a mesh-free method based on first-order shear deformation theory and the shape functions constructed using moving least squares approximation. The sandwich plates are rested on a Pastern...

Ensuring the stability and integrity of underground gas storage salt caverns is a very complicated subject due to the non-linear and time-dependent behavior of rock salts under complicated thermal and mechanical loading conditions. For this reason, pressure and temperature fluctuations in the caverns and their surrounding strata must be integrated into the analysis and the numerical tools that ...

We demonstrate single-shot readout of a silicon quantum dot spin qubit, and we measure the spin relaxation time T1. We show that the rate of spin loading can be tuned by an order of magnitude by changing the amplitude of a pulsed-gate voltage, and the fraction of spin-up electrons loaded can also be controlled. This tunability arises because electron spins can be loaded through an orbital excit...

This paper focuses on the effect of high temperatures on an elastomeric component. There are two sources of temperature rise, a hot environment and internal heating due to mechanical loading such as occurs during cyclic loading. Internal mechanical heating can lead to a substantial temperatures occuring within the component. When the temperature of the material becomes sufficiently high, macrom...
