Aging Effect in the Wettability of Nickel Nanorod Arrays
… their water contact angles as a function of "aging" time in air. The nickel nanorod arrays were deposited on silicon substrates by DC magnetron sputtering using an oblique angle of 85° with respect to the substrate normal. By changing the deposition time from 10 to 90 min., the diameter, …

Aging effect on successful reactive-recovery from unexpected slips: a 3D lower extremity joint moment analysis
… perturbation experimental data. In addition, the aging effect on the joint moment generation in both normal walking and reactive-recovery conditions was examined. Dataset collected during previous slip and fall experiments, which were conducted in a typical gait analysis setting, were analyzed in …

Aging Effects of the Cathode and Determination of Single Electrode Performance in a Solid Oxide Fuel Cell
… tens of hours in a cell at open circuit voltage (Aging effect). This aging effect was reversible during temperature cycles between 800ºC and 700ºC. We explored this phenomenon via electrochemical techniques (EIS and CV), with the purpose of discovering the true physical source. From the …

A theory for the time dependent yielding and creep of clay
… compression (secondary compression) and the "aging" effect, or increase in preconsolidation pressure with time under sustained load. The theory appears to be consistent with many aspects of the consolidation behavior of real clays, including: (1) secondary compression, (2) aging, (3) different …

X-ray analysis of the time-softening property of a lead tin alloy
… does occur in conjunction with the softening effect. Apparently also the softening effect observed in the lead-tin alloy is a definite phenomenon distinct from the “over-aging” effect in which an alloy aged at high temperature increases rapidly in hardness until a certain critical hardness is …

Advanced modeling of planarization processes for integrated circuit fabrication
… The wafer-level model investigates the CMP tool effects on wafer-level pressure non-uniformity. The die-level model is developed to study chip-scale non-uniformity induced by layout pattern density dependence and CMP pad properties. The particle-level model focuses on the contact mechanism …

Tillage effects on soil-water-air matrix and prediction of soil bulk density from cone index data
… of this study was to evaluate the long-term effects of the no-till method on bulk density, capillary porosity, noncapillary porosity, void ratio, and cone index of the soil. Although tillage affected cone index significantly, moisture variations caused difficulty in interpreting the results. …

Investigating and Understanding the Effects of Reclaimed Asphalt Pavement and Shingles on the Rheology and Performance Grading of Asphalt Cement.
… the sector or contractors on the appropriate and effective amount of RAP/RAS that can be used, which has created a monitoring problem on its usage. The effects that RAP (Highway 7, 11, 403) and RAS have on the rheology of two sources of virgin asphalts of the same grade was studied under this …

Influence of Low Temperature Degradation on Microstructural Integrity of Zirconia Dental Implants
… failure. Nevertheless, no study has reported the effects on commercially available Zirconia dental implants. The primary aims of this study was to determine if there is a correlation between ageing duration and 1) depth of tetragonal-monoclinic phase transformation (t-m transformation), 2) …

DESIGN AND TEST OF DIGITAL CIRCUITS AND SYSTEMS USING CMOS AND EMERGING RESISTIVE DEVICES
… current-based designs for neural networks. CMOS aging impacts the total synaptic current and this impacts the accuracy. Chapter 5 introduces an enhanced memristive crossbar array (MCA) based analog neural network architecture to improve reliability due to the aging effect. A built-in …

Reliability-based co-design and its applications to wind energy and mobile energy storage systems
… are strongly coupled. Neglecting this coupling effect may cause an imbalance in the feasible design spaces of plant design and control design, such as over-constrained operation conditions, over design, or requirement of skilled operators, which hinders the development of autonomous systems. On …

Analysis of early lactation reproductive characteristics in Holstein cows
… apparent decrease in oocyte quality, despite the aging effect on follicle numbers. This study demonstrated that conditions related to early lactation have a negative effect on oocyte quality and endocrine measures of dairy cattle and that animals of different ages are differentially affected.

Evaluating the Hydrologic and Thermal Performance of a Green Roof in Syracuse: Measurements and Modeling of a Full-Scale System
… of green roof behavior, including the aging effect of soil media, ET, and heat transfer, and by developing methods to predict the hydrologic performance and related thermal properties of green roofs. In this research, rainfall, runoff, soil moisture content, and meteorological data have …

Protective effects of regular exercise and Korea red ginseng against high-fat diet-increased renal injury in ᴅ-galactose-induced aging rats
A decline in renal function is seen commonly in aging. Aging further increase oxidative stress in the kidney and are associated with reduced renal function. Aging is progressive accumulation of oxidative agents. Advanced glycation end products (AGEs) and advanced lipoxidation end products (ALEs) …

Structural Investigations of Highly Strictive Materials
… time distribution. In KNN textured ceramics, an aging effect was found to exist in the orthorhombic single phase field, not only in the orthorhombic and tetragonal two-phase field as previously reported. No variation of phase structure was revealed between before and after aging states. However, …

Intracellular signaling cascades in the dopaminergic specification of fetal mesencephalic neural progenitor cells.
… from long-term expanded cultures suggesting an ‘aging’ effect of in vitro conditions. IL-1 was a potent inducer of the dopaminergic neuronal phenotype in short-term expanded in vitro cultures and was expressed in vitro as well as in vivo at E14. Several important conclusions concerning fetal …
