The direct current potential drop (DCPD) technique may be used in crack propagation tests to measure the growth rate (CGR). Potential probes attached specimen allow variation of length estimated. In this research, DCPD using one single probe was applied solid bar specimens (i.e., without any initial notch or crack) subjected low-cycle fatigue testing a simulated pressurized water reactor (PWR) ...

With the increased requirement of miniaturization structures on hard and brittle substrates, micro abrasive air jet turning technology has become a promising machining for manufacturing structures. This paper presents an investigation multi-pass radial-mode fused silica. The effect parameters depth cut materials removal rate was analyzed. waviness striation formation mechanisms were studied. It...

Increasing the knowledge in climate radiative feedbacks is critical for current climate studies. This work focuses on short-term relationships between global mean surface temperature and top-of-atmosphere (TOA) net radiation. The relationships may be used to characterize the climate feedback as suggested by some recent studies. As those recent studies, an energy balance model with ocean mixed l...

Density and magnetic fluctuations arising spontaneously in a narrow field-aligned density striation in a magnetized discharge He plasma are found to exhibit a radial eigenmode structure. The nature of the fluctuations depends upon the electron plasma beta, be . For be greater than the electron to ion mass ratio (be.m/M ) the frequency spectrum exhibits sharply peaked eigenfrequencies with the d...

This study presents a computationally based methodology to estimate identification error rates of striation patterns in as modern and objective way as possible. A database was assembled consisting of 3D striation patterns generated by standard tip screwdrivers and 9-mm Glock firing pin apertures. These toolmark surfaces were digitally recorded by white light confocal microscopy commonly used fo...

The regulatory mechanism of sarcomeric activity has not been fully clarified yet because of its complex and cooperative nature, which involves both Ca(2+) and cross-bridge binding to the thin filament. To reveal the mechanism of regulation mediated by the cross-bridges, separately from the effect of Ca(2+), we investigated the force-sarcomere length (SL) relationship in rabbit skeletal myofibri...

Quartz veins in the Jendi area and its surroundings are formed by geological structures with distributions patterns that need to be known. This study uses data on striation, quartz vein orientation, metal content veins. The use of this aims determine relationship between direction pattern mineral main structure forms it. results can useful determining structural model distribution area. researc...

In the Kundt’s experiment of acoustic resonance in closed tubes, two characteristic lengths were observed: one is wave-length sound waves and other scale dust striation. The latter has remained unresolved for its formation mechanism. Based on Fluid Gauge Theory proposed recently by author, mechanism striation studied. When weak enough, unobserved. Once wave intensity exceeds a threshold value, ...
