Ke Zhang, Lei Cheng, Satoshi Imazato, Joseph M. Antonucci, Nancy Lin, Sheng Lin-Gibson, Yuxing Bai, Hockin H. Xu
… primers were tested: SBMP primer P, P + 5% MDPB, P + 0.05% NAg, and P + 5% MDPB + 0.05% NAg. Dentin shear bond strengths were measured. A … a much stronger effect than using each agent alone (p < 0.05), increasing the inhibition zone size and reducing the …

Injectable Calcium Phosphate Cement: Effects of Powder-to-Liquid Ratio and Needle Size

July 16, 2007
Author(s)
Elena F. Burguera, Hockin D. Xu, Limin Sun
… to (144 17) N using the 21-gauge needle (Tukey s at p of 0.05). Varying the powder/liquid mass ratio from 2 to 4 also … it decreased to (70 12) % at powder/liquid of 3.5 (p < 0.05). A relationship was established between the injection … lumen cross-sectional area, A, for CPCD: F = 5.0 + 38.7 / A0.8. The flexural strength (mean sd; n = 5) increased …

Thermal Diffusivity of AIN Using the Photothermal Deflection Technique

February 19, 2017
Author(s)
E J. Gonzalez
The thermal conductivity of AIN specimens doped with Y2O3(5 wt.%) was determined using the photothermal deflection technique. The results agree within 10% of measurements previously made using the laser flash method. Thermal measurements on as-fired thin

Thermopower of Co-doped FeSe0.82

April 1, 2009
Author(s)
Evan L. Thomas, Winnie K. Wong-Ng, Daniel P. Phelan
… The effect of cobalt doping (0.05 ≤ x ≤ 0.50) on the thermopower of the newly discovered …

Impulse Spectrum Amplitude Uncertainty Analysis

October 1, 2006
Author(s)
Nicholas Paulter, Donald R. Larson
A detailed uncertainty analysis for an impulse spectrum amplitude measurement system is presented. This analysis includes consideration of effects such as temperature, computation algorithms, history of instrument performance, equipment limitations, and

Temporal Character of Pulsed-Laser Cone Emission

August 1, 2001
Author(s)
W Gawlik, R Shuker, Alan Gallagher
Temporal character of cone emission from Sr vapor excited with 3 ns, near-resonant laser pulses is studied with 0.5 ns resolution. The cone pulses appear significantly narrower than the laser pulse. Their properties (amplitude, width, energy, delay and

Capacitive Displacement Sensor for Detecting Planar Submicrometer Motion

June 1, 2016
Author(s)
Svetlana Avramov-Zamurovic1, Jae M. Yoo, Nicholas Dagalakis
This paper describes the design of a very simple displacement sensor that measures the displacement of an object by measuring the change in capacitance due to the movement of this object in the sensor fringing electric field. Two sensor geometries with

Measurement of Impulse Spectrum Amplitude for Use in EMI Susceptibility Tests

March 1, 2006
Author(s)
Nicholas Paulter, Donald R. Larson
A system for measuring the impulse spectrum amplitude of the output of impulse generators and the response of receivers is described. The calibration procedures used in this measurement system were recently modified, which resulted in a reduction in the

Measurements and Modeling Study on a High-Aromatic Diesel Fuel

January 31, 2012
Author(s)
Bret Windom, Marcia L. Huber, Thomas J. Bruno, A L. Lown, C T. Lira
The increasing cost of diesel fuel, potential for supply disruptions, and environmental concerns have resulted in a great deal of research to improve the performance and efficiency of diesel engines. This includes significant efforts in the reformulation

Comparison of Submicron Particle Analysis by Auger Electron Spectroscopy, Time-of-Flight Secondary Ion Mass Spectrometry, and Secondary Electron Microscopy With Energy Dispersive X-Ray Spectroscopy.

July 31, 1996
Author(s)
George W. Mulholland, K D. Childs, D Narum, L A. LaVanier, P M. Lindley, B W. Schueler, A C. Diebold
Particulate contamination can result in a significant yield loss during semiconductor device fabrication. As device design rule dimensions decrease the critical defect size also decreases, resulting in the need to analyze smaller defects. Current
