During the second year of life, the rate at which most children learn words accelerates dramatically, the so–called “vocabulary explosion”. Most accounts posit changes in the child or specialized learning mechanisms to account for this sudden change. However, recently McMurray (2007) demonstrated that acceleration is a mathematical consequence of parallel learning and the statistical distributi...

This paper aims to develop a model for simulating the electric double layer dynamics in CV measurements while simultaneously accounting for transport phenomena in both the electrode and the electrolyte. It also aims (i) to identify the dimensionless parameters that govern the CV measurements, (ii) to provide a physical interpretation of the shape of CV curves, and (iii) to investigate the effec...

the forced convection heat transfer of turbulent al2o3-water nanofluid flow inside the grooved tubeswith the different aspect ratio of the rectangular grooves is numerically investigated. the governingequations have been solved using finite volume method (fvm) coupled with simple algorithm. it isassumed the heat flux is constant on the grooved walls. the single-phase approach is applied for the...

In this research, turbulent MHD convection of liquid metal with constant and variable properties is investigated numerically. The finite volume method is applied to model the fluid flow and natural convection heat transfer in a square cavity. The fluid flow and heat transfer were simulated and compared for two cases constant and variable properties. It is observed that for the case variable pro...

BACKGROUND Age, estimated glomerular renal function (eGFR), and ejection fraction are preprocedural predictors of contrast-induced acute kidney injury (CI-AKI) after primary percutaneous coronary intervention. The effect of renal function-adjusted contrast volume (CV) remains not totally explored, and a threshold has not yet been established. METHODS AND RESULTS Logistic regression and receiv...

in the present work a two dimensional numerical investigation of steam flows in a turbine blade passage is performed. a finite volume approach has been used and the pressure–velocity coupling is resolved using the simple algorithm. the purpose of this paper is to find that one of the used turbulent models is better for this kind of studies. a structured mesh arrangement with boundary layer mesh...

A model of formation, development, and acoustic properties of the bubble cloud resulting from an underwater explosion is presented. The model includes several parts: explosion globe dynamics, initial break-up of the explosion globe, turbulence created by the explosion globe fragmentation, and further break-up of the bubbles by the turbulence. The time history of the bubble cloud properties is c...

this experiment was designed and conducted to increase to yield as well as quality of greenhouse cut-rose. the experiment was conducted in a factorial arrangement, based upon a completely randomized design of three replications, under hydroponic conditions. the study was followed with the aim of investigating the effects of cultivar type (‘bull's eye’-‘cherry brandy’), pot volume (5-8l) an...
