The use of strain gages for low temperature thermal expansion measurements is increasing, due to it's convenience, and relative accuracy. The determination of thermal expansion with strain gages is complicated by "thermal output strain", a phenomena caused by the temperature dependence of the gage. If thermal output strain is properly compensated , strain gages may be used to measure thermal ex...

Cement composites with hybrid conductive fillers carbon nanotubes (CNT) and graphite products (GP), have been tested as strain sensors under varying temperatures (0 °C–60 °C), moisture conditions (0%–100% saturation degree (SD)). pastes 1% CNT 5% GP (purified expanded graphite) presented resistivity values between 50 75 Ohm·cm, their sensing response was observed to be independent of the loadin...

in this research, the frequency of the jet streams associated with extreme and pervasive precipitation has been analyzed using environmental to circulation approach. based on the 99th percentile index, 109 days of the extreme and pervasive precipitation was selected from the irimo data base ( including 33 synoptic, climatic and rain gage stations during 15992 days from farvardin, 1st, 1340 to d...

In the continuing series of interviews with famous Neuroscientists, I had the pleasure of meeting with Fred (Rusty) Gage at the last SfN meeting in Washington, DC. I was accompanied by a former student of mine, Anne Fagan, who had also been a graduate student in Rusty’s lab when he was at UCSD. Again, my main question was: “How did you become a famous neuroscientist?” I gave Rusty the choice of...

OBJECTIVES Quarantine measure for prevention of epidemic disease and further evaluations of their efficiency are possible only by elaborating analyses of imported cases. The purpose of this study was to analyze descriptive epidemiological characteristics of pandemic influenza A (H1N1) cases imported to Korea. METHODS We collected two sets of data. The first set, comprised daily reported cases...

Digital tuning systems are fast replacing the conventional mechanical systems in AM/FM and television receivers. The desirability of the digital approach is mainly due to the following features: Y Precise tuning of station frequencies Y Exact digital frequency display Y Keyboard entry of desired frequency Y Virtually unlimited station memory Y Up/down scanning through the band Y Station ‘‘searc...

Given a Hausdorff uniform space $$X$$ with the countable gage of pseudometrics uniformity , we introduce concept approximate variation function $$f$$ mapping subset $$T$$ reals into : this is infimum family Jordan-type variations all functions $$g:T\to X$$ which differ from in each pseudometric, generated by pseudometric gage, not greater than $$\varepsilon>0$$ . We prove following compactness ...

In 1963, Lopez, Edelist, and Katz demonstrated that electrical stimulation could be used for slowing the heart below its spontaneous rate. These workers noted when pacing the heart of a dog that sudden slowing could consistently be produced when the impulse persisted for about 150 m.sec. They were able to show that this effect was due to stimulation at the "make" and the "break" of the impulse,...

Strain measurements must often be made in the presence of electric and/or magnetic fields which can superimpose electrical noise on the measurement signals. If not controlled, the noise can lead to inaccurate results and incorrect interpretation of the strain signals; and, in severe cases, can obscure the strain signals altogether. In order to control the noise level, and maximize the signal-to...
