Effectiveness of Essence of Chicken in Improving Cognitive Function in Young People Under Work-Related Stress: A Randomized Double-Blind Trial.

Work-related stress (WS) can result in considerable and extensive changes in physiological and psychological performance. WS beyond the optimal levels induces anxiety, confusion, exhaustion, and burnout. Chronic WS affects neurocognitive performance, particularly attention and visuospatial memory.

Applying importance-performance analysis to patient safety culture.

Purpose: The Sexton et al.'s (2006) safety attitudes questionnaire (SAQ) has been widely used to assess staff's attitudes towards patient safety in healthcare organizations. However, to date there have been few studies that discuss the perceptions of patient safety both from hospital staff and upper management.

Sophisticated oil film geometries through incomplete electrical dewetting by feedback control and Fourier construction.

Existing techniques for electronic control of the interface between two immiscible fluids are typically limited to simple periodic geometries (symmetric waves) or spherical geometries (only two principle radii of curvature). Presented here, is a new technique with much more sophisticated electronic control of fluid meniscus geometry. Previously undemonstrated two-fluid interfaces, such as asymmetric saw-tooth profiles, are created by dynamic modulation of an incomplete dewetting state for an oil film covering an array of control electrodes, with the oil film itself covered by an electrically conductive fluid acting as the ground electrode.

Intruder-induced asymmetry in compartmentalized granular gases.

The clustering behavior of a compartmentalized monodisperse granular gas with the addition of one heavy intruding particle is investigated experimentally. Depending on the number of particles, the presence of a heavy intruder leads to three population states: a homogeneous state, an expelled clustering state, and a fully clustering state. These states are found to be consistent with the clustering of a purely monodisperse granular gas in an asymmetric compartmentalized structure.

Two types of oscillation in unequally compartmentalized granular gases.

Granular oscillation in an unequally two-compartmentalized system is investigated experimentally, yielding two time periods: τ(LS) represents the time period for particles moving from the large to the small compartment, and τ(SL) is the time needed for movement in a reverse direction. We construct the phase diagram for the unequal system, discovering that there exist two different granular oscillation states. In the GOI state, τ(LS)>τ(SL) is observed, and (τ(LS)-τ(SL)) increases as the difference between the two compartment widths is enlarged.

Intruder-induced change in condensation temperature of granular gases.

The process from a gaseous state to a clustering state for a compartmentalized monodisperse granular gas is accompanied by a drop in the granular temperature to a condensation point. We show experimentally that adding an intruder generally results in a decrease in the condensation point, and a heavier intruder makes this decrease more pronounced. However, once the Brazil nut effect (the intruder on the top of clustering grains) occurs, the condensation point will rise.
