Two hundred and seventy mice were evaluated at three exposure durations (5, 10 and 20 min) and at six peak acoustic pressure levels (0, 65, 80, 87, 100 and 145 kPa) with 15 mice per exposure condition, at an ultrasonic frequency of 30 kHz modulated at 120 Hz. Threshold acoustic pressure levels for hemorrhage in mouse lung exposed for the three exposure durations appear to be in the range of 100...

Decreasing bag limits is a management mechanism for enhancing size structure of Bluegill Lepomis macrochirus. However, restrictive can promote culling, where an angler returns live fish to the water in exchange another. Little known about effect culling on ice-angled fishes. Our objective was compare effects confinement methods (reference, ice well, and bucket) holding durations (0, 1, 2, or 5 ...

A number of different researchers have reported a substantial degree of variability in how American English /r/ coarticulates with neighboring segments. Acoustic and articulatory data were used to investigate this variability for speakers of "rhotic" American English dialects. Three issues were addressed: (1) the degree to which the F3 trajectory is affected by segmental context and stress, (2)...

Introduction: Stress is a main factor influencing brain functions as revealed by the electroencephalogram (EEG) recordings. Moreover, different stress durations seemingly cause perturbations in brain waves and lead to mental disorders. This study investigates the effects of acute, sub-chronic and chronic stress on EEG in rats.  Methods: Twenty-eight Wistar adult male rats were randomly all...

A review of studies that have examined the integration of Web 2.0 tools into E-Learning 2.0 within built environment educational programs is undertaken. An analysis of studies undertaken reveals five core themes can be derived: (1) students using Web 2.0 demonstrate the capability for effective learning; (2) Skills learned via Web 2.0 can be transferred to the work and untrained tasks; (3) limi...

A number of different researchers have reported a substantial degree of variability in how American English /./ coarticulates with neighboring segments. Acoustic and articulatory data were used to investigate this variability for speakers of ‘‘rhotic’’ American English dialects. Three issues were addressed: ~1! the degree to which the F3 trajectory is affected by segmental context and stress, ~...

Background: The effect of corticosteroid therapy on corneal wound healing is controversial. The objective of this study was to evaluate the effects of combination therapy with dexametha-sone and acetylcysteine at different times and durations on experimentally-induced corneal wounds and haze in rabbits. Methods: Eighteen adult New Zealand white rabbits were divided into three groups of ...

Christopher H. Wheeler is a research officer in the Research division of the Bank. He previously was an assistant professor of economics at Tulane University in New Orleans. Wheeler received his doctoral and master’s degrees in economics from the University of Wisconsin-Madison in 1998 and 1995, respectively, and his bachelor’s degree in economics from Colby College in Waterville, Maine, in 199...

Experiments were performed to examine the temporal masking properties of multidimensional tactual stimulation patterns delivered to the left index finger. The stimuli consisted of fixed-frequency sinusoidal motions in the kinesthetic (2 or 4 Hz), midfrequency (30 Hz), and cutaneous (300 Hz) frequency ranges. Seven stimuli composed of one, two, or three spectral components were constructed at ea...
