Abstract:

Tests of verbal fluency provide brief and sensitive measures of the deficits in rapidly retrieving overlearned information common in multiple sclerosis (MS). Production of words that begin with the letters F, A, and S is the verbal fluency measure most often used with patients who are fluent in English. However, because of frequency of words beginning with certain letters varies from one language to another, it is unlikely that any fixed set of letters will be appropriate for multicenter trials that involve patients who are fluent in different languages. A possible alternative involves using s

Abstract According to the Body-Specificity Hypothesis, humans preferentially associate positive features with their dominant side with which they interact more fluently, and negatives features with their non-dominant side with which they act more clumsily.

Across the two studies, our findings offered general support for the Body-Specificity Hypothesis with important caveats. Specifically, the body-specificity eff

Abstract:

Abstract This study focuses on the flow dynamics downstream of cylindrical bluff bodies with flat, concave, and convex surfaces, where a fuel jet is injected at the bluff body center and the oxidiser flows through a duct surrounding the bluff body. The flow is assumed to be non-reactive and the main attention is put to the mixing process. The research is carried out using the Large Eddy Simulation (LES) method, employing two computational codes: ANSYS Fluent and an in-house high-order code SAILOR. We analyze the extent to which the inclination of the upper bluff body surface modifies the flow

Abstract:

The auger-type heat exchanger possesses many merits, such as compact structure, high thermal efficiency, and is mainly used in food, oil, natural gas and chemical industry. The shell-side fluid characteristics are calculated through FLUENT based on computational fluid dynamics (CFD) theory, and the typical regional and cross-section of the shell-side fluid are analyzed in detail. The results show that current "dead zone" exists in the head of the receiver at the entrance and the core body, which is not conducive to the efficiency and service life of the heat exchanger, and a large pressure exi

An argon magnetic fluid is a collection of free charged particles moving in random directions especially that is a weakly ionized argon discharge and on the average, electrically neutral. Two-dimensional numerical steady-state model of an argon magnetic fluid generator is presented to investigate the thermodynamic behaviors and the distribution of current density. Computational fluid dynamics codes, OpenFOAM and Fluent, are utilized in a modified form to model the argon magnetic flow inside the generator.

The distribution of PM2.5 around a thermal manikin with realistic female body shape in a naturally ventilated room has been modelled. The health risk (HR) due to inhalation of the PM2.5 has been quantified by integrating the pollutants mass flux over the boundaries of a virtual box around the mannequin’s head (the breathing zone). By the same approach HR is evaluated over the boundaries of another virtual box that surrounds the manikins body and defines the occupied zone.

In this study, the focal challenge is reducing drag around the Ahmed body, a critical concern in aerodynamics. The approach involves perforating a rectangular conduit inside the body, redirecting part of the airflow from the front to the rear end to minimize drag. Using Ansys Fluent CFD software and the SST k-w turbulence model, a numerical model for turbulent flow around a 3D body has been developed. Through a series of numerical simulations, variations in the conduit’s position relative to the lowest slanted edge of the body have been explored. At the optimal position with the lowest drag, a

Oral fluency is a skill that requires constant practice in an ESL classroom in order to make meaningful development. In general, when we discuss fluency, we are referring to the ease with which pupils speak, their speech rate, their pauses, and the language they can easily create in between. In an ideal scenario, the greatest method to learn to speak English effectively is to be exposed to the language on a daily basis through frequent discussion with English speakers on a range of themes. Regretfully, hardly many English language learners get the chance to practice speaking in a situation tha
