The framework of this article is modelling applied to sheries. It aims at relating some classical stock-recruitment curves to a dynamic structured model, consisting of the adults stages of the stock and a pre-recruits stage (i.e. eggs, larvae, juveniles). The main result is that no functional stock-recruitment relationship can be found, unless further restrictive assumptions are added to the mo...

Performance deteriorates when subjects must shift between two different tasks relative to performing either task separately. This switching cost is thought to result from executive processes that are not inherent to the component operations of either task when performed alone. Medial and dorsolateral frontal cortices are theorized to subserve these executive processes. Here we show that larger ...

During explosive movements and potentially injurious situations the ability to rapidly generate torque is critical. Previous research has suggested different phases of rate of torque development (RTD) are differentiately controlled. However, the extent to which supraspinal and spinal mechanisms predict RTD at different time intervals is unknown. RTD of the plantarflexors across various phases o...

Abstract In recent years, the practice of using corporate websites to recruit job applicants has increased steadily. The aim of this paper is to review and analyze the E- recruitment in Iran. in this article, we examine e-recruitment situation in premier 100 Iranian organizations through websites content analysis. These top 100 organizations were introduced by the IMI in 1390. This ranking is ...

The Hoffmann reflex has been the tool most commonly used in exercise studies to investigate modulations in spinal excitability. However, the evolution of electromyographic responses with the increase in stimulation intensity has rarely been assessed when the muscle is active. The purpose of this study was thus to identify that part of the recruitment curve at which the investigation of the Hoff...

BACKGROUND Ventilatory pressures should target the range between the upper and lower inflection point of the pressure volume curve in order to avoid atelecto- and volutrauma. During high-frequency oscillatory ventilation (HFOV), this range is difficult to determine. Quadrant impedance measurement (QIM) has recently been shown to allow accurate and precise measurement of lung volume changes duri...

The chirp-evoked ABR has been regarded as a more synchronous response than the click-evoked ABR, referring to the belief that the chirp stimulates lower-, mid-, and higher-frequency regions of the cochlea simultaneously. In this study a variety of tools were used to analyze the synchronicity of ABRs evoked by chirp- and click-stimuli at 40 dB HL in 32 normal hearing subjects aged 18 to 55 years...

Digital-imaging microscopy of Fura-2-loaded pancreatic acinar cells revealed that the C-terminal octapeptide of cholecystokinin (CCKe) dose-dependently recruited 94% of freshly isolated acinar cells in terms of receptor-evoked Ca2+ mobilization. Maximal and half-maximal cell-recruitment were reached with 0.1 nM and 16.8 pM CCKe, respectively. The upstroke of the dose-recruitment curve consisted...

INTRODUCTION Lung-protective ventilation aims at using low tidal volumes (VT) at optimum positive end-expiratory pressures (PEEP). Optimum PEEP should recruit atelectatic lung regions and avoid tidal recruitment and end-inspiratory overinflation. We examined the effect of VT and PEEP on ventilation distribution, regional respiratory system compliance (C(RS)), and end-expiratory lung volume (EEL...
