Annual variation in timing, orientation and effects of weather on Jefferson salamander (Ambystoma jeffersonianum) and spotted salamander (Ambystoma maculatum) movements in central Kentucky
… in relation to amphibian movements included barometric pressure, cumulative precipitation, temperature and relative humidity. Several species used the ephemeral pond during the study but few successfully reproduced. Jefferson salamanders (Ambystoma jeffersonianum) and spotted salamanders (A. …

Ground water reservoir response to earth tides
… for non tidal water level fluctuations and barometric pressure effects were made. Porosities of .22 near Blacksburg, Virginia, and .098 and .05 near Cripple Creek, Virginia, at depths of 156, 300, and 425 meters respectively were computed. An analysis of variability yields errors of about …

Environmental predictors of Carcharodon carcharias presence at two popular beaches in False Bay, South Africa using acoustic telemetry
… cloud cover, lunar phase, tide height, barometric pressure, year, season and time of day as predictor variables. Water temperature was a significant predictor of white sharks at Muizenberg beach during summer, autumn and winter while wind speed, time of day and barometric pressure were …

Numerical modeling of methane venting from lake sediments
… load on the sediments, from both water level and barometric pressure, appear to trigger free gas bubbling (ebullition). We develop a model of methane bubble ow through the sediments, forced by changes in hydrostatic load. The mechanistic, numerical model is tuned to and compared against ebullition …

Energy conservation with clothes dryers: evaluation of techniques
… times. Room temperature, relative humidity, and barometric pressure were monitored. Statistical procedures utilized in data analysis included Pearson product-moment correlation coefficients, means, standard deviations, ranges and analysis of variance. The combination requiring the most energy, …

Spatial and Temporal Patterns of Anadromous Fish Passage at Boshers Dam Vertical Slot Fishway on the James River, Richmond, Virginia
… temperature trend. Day length, and indirectly, barometric pressure also played a role in passage. Sea lamprey and American shad peak passage rates were dissimilar when comparing preferred water temperature ranges. Sea lamprey peaked (5.30/hr) at 16-17.99°C, while American shad peaked (1.05/hr) …

Development of optically interrogated diagnostic systems within materials ageing experiments
… diagnostic options for measuring temperature, barometric pressure, and gaseous concentrations were reviewed. The long-term suitability of fibre Bragg grating (FBG) temperature sensors, fibre Fabry-Pérot (FFP) pressure sensors, O2sensing fluorescence probes, and optical fibre switches were assessed …

An investigation of the performance of a stationary siphoning type of roof ventilator
… listed are for standard air at 70°F and a barometric pressure of 29.92 inches of mercury. The tests revealed several interesting facts. The open stacks were found to be more effective than the Ventilators when the wind Velocity across the Ventilators was less than about 4.5 miles per hour; …
