A feature-matching model to account for the effects of novelty and significance on psychophysiological responsivity is presented. 2 experiments based on a modified version of the Guilty Knowledge Technique were designed to test predictions derived from the proposed model. Results of Experiment 1 demonstrated that electrodermal responsivity to the test stimulus reflected the degree to which the ...

We analyze the steady-state behavior of a general mathematical model for reversible galvanic cells, such as redox flow cells, reversible solid oxide fuel cells, and rechargeable batteries. We consider not only operation in the galvanic discharging mode, spontaneously generating a positive current against an external load, but also operation in two modes which require a net input of electrical e...

Siderite (FeCO3) and cementite (Fe3C) layers develop naturally on carbon steel surfaces in aqueous dioxide (CO2) environments. This study evaluates galvanic corrosion induced by such when coupled to bare steel. In CO2-saturated, 50 °C, pH 5 conditions, the Fe3C-filmed acted as net cathode, significantly enhancing rates. Galvanic currents FeCO3-filmed were much lower, with FeCO3 removed from sur...

PURPOSE The purpose of this study was to evaluate cell toxicity due to ion release caused by galvanic corrosion as a result of contact between base metal and titanium. MATERIALS AND METHODS It was hypothesized that Nickel (Ni)-Chromium (Cr) alloys with different compositions possess different corrosion resistances when contacted with titanium abutment, and therefore in this study, specimens (...

BACKGROUND The weightlessness caused by prolonged bed rest results in changes in cerebral circulation and thus, brain functions, which is of interest. METHODS We investigated the effects of 45-day, -6° head-down bed rest, which stimulated microgravity, on working memory in 16 healthy male participants. The 2-back task was used to test the working memory variations on the 2nd day before bed re...

The cores of electrical machines are generally punched and laminated to reduce the eddy current losses. These manufacturing processes such as punching and cutting deform the electrical sheets and deteriorate its magnetic properties. Burrs are formed due to plastic deformation of electrical sheets. Burr formed due to punching on the edges of laminated sheets impairs the insulation of adjacent sh...

This study investigates the effects of two different catalytic activation techniques on the thermal performance of the flip-chip heat spreaders. The two activation techniques studied are thin nickel–copper strike and galvanic initiation. Thermal diffusivity and surface roughness of these heat spreaders were studied using the Nano-flash Apparatus and Infinite Focus Microscopy. High temperature s...

Recent advances in biomedical sensors, data acquisition techniques, microelectronics and wireless communication systems opened up the use of wearable technology for ehealth monitoring. We introduce a galvanic coupled intrabody communication for monitoring human body hydration. Studies in hydration provide the information necessary for understanding the desired fluid levels for optimal performan...

Emotional arousal during relationship conflict is a major target for intervention in couple therapies. The current study examines changes in conflict-related emotional arousal in 104 couples that participated in a randomized clinical trial of two behaviorally-based couple therapies. Emotional arousal is measured using mean fundamental frequency of spouse's speech, and changes in emotional arous...
