Method and apparatus for minimizing multiple degree of freedom vibration transmission between two regions of a structure

Arrays of actuators are affixed to structural elements to impede the transmission of vibrational energy. A single pair is used to provide control of bending and extensional waves and two pairs are used to control torsional motion. The arrays are applied to a wide variety of structural elements such as a beam structure that is part of a larger framework that may or may not support a rigid or non-rigid skin. Electrical excitation is applied to the actuators that generate forces on the structure. These electrical inputs may be adjusted in their amplitude and phase by a controller in communication with appropriate vibrational wave sensors to impede the flow of vibrational power in all of the above mentioned wave forms beyond the actuator location. Additional sensor elements can be used to monitor the performance and adjust the electrical inputs to maximize the attenuation of vibrational energy

Selective Information Processing of Body Size and Food Related Stimuli in Women Who Are Preoccupied With Body Size.

Overconcern or preoccupation with body size and weight is a central psychopathological feature of the eating disorders. The overconcern with body size is considered to be a function of fear of weight gain or fear of fatness . Cognitive theories of psychopathology have hypothesized that fear results in an increased activation of cognitive structures associated with the feared object. This increased activation (priming) is hypothesized to enhance the processing of information related to the feared object. This study tested this hypothesis using a lexical decision task. Individuals with extreme body size preoccupation were evaluated for a selective information processing of body size related words and food related words. Subjects with high body size preoccupation, i.e. a score of 110 or greater on the Body Shape Questionnaire (BSQ), correctly identified significantly more food and body words when compared to subjects with low concern about body size, i.e. a score of 50 or less on the BSQ. The groups did not differ on identification of control words. These results were interpreted as support for the anxiety model of eating disorders and cognitive theories of psychopathology

Factors influencing foraging decisions in ruddy turnstones Arenaria interpres (L.)

Animals must assimilate energy to survive and reproduce, but foraging conflicts with other demands on an animal's time. We know very little about how animals resolve these conflicts in natural settings. I studied foraging choices made by ruddy turnstones Arenaria interpres (L.) using rocky coastline in north-east England. In particular I explored how foraging decisions varied with resource quality, the predictability of patch appearance, and perceived predation risk while using alternative patches. This study includes the first quantitative investigation into the use of beach-cast wrack by shorebirds. Energy intake per unit time by foragers on supratidal habitats was much higher than on intertidal habitats. However, birds exclusively used intertidal habitats when these were exposed by the tide, and moved onto supratidal habitats only over the high-water period. Moreover, the number of birds feeding over a given high tide did not depend on supratidal food availability. These results suggested that there were costs to foraging supratidally. Were some foragers being forced to pay these costs because of low foraging efficiency, or did some accept the costs because of other associated benefits? The use of supratidal habitats appeared to incur elevated predation risk for foragers; they were situated in areas where raptors could approach a foraging flock relatively closely before being detected. Accordingly, vigilance was much higher than expected on supratidal habitats, and increased with distance from the water's edge. Birds that regularly fed supratidally tended to be males, older and higher-ranking, and had smaller, less patchy home ranges than birds that rarely fed supratidally. This suggests that some birds were paying the cost of elevated predation risk associated with supratidal feeding for the benefits of stable group membership and higher social status, while others minimised their need for supratidal feeding by spatially tracking the variation in intertidal habitat quality
