Crystallization, Melting Behavior, Physical Properties, and Physical Aging of Ethylene/1-Octene Copolymers
… the enthalpy recovery in glasses after physical aging. Using this analogy, a calorimetry-aging rate is defined, which quantifies the change in the low endotherm temperature with time. Similarly a density-aging rate is defined from the evolution of density with time. A non-classical creep behavior …

Environmental and age effects on methylation changes in human brain and blood cells
… DNA methylation may 1 e associated with disease, aging, the rate of aging and genetics. In this thesis, age is accurately predicted from DNA methylation in brain and blood tissues using two different algorithms, Random Forest and Linear Regression. Relationships between DNA methylation, genetics, …

Architectural Techniques to Mitigate the Effect of Spatial and Temporal Variations in Processors
… this problem, we show how to hide the effects of aging and slow it down. Our framework is called Facelift. It hides aging through aging-driven application scheduling. It slows down aging by applying voltage changes at key times---it uses a non-linear optimization algorithm to carefully balance the …

Impact of laboratory simulated aging on asphalt concrete flexibility
The aging of asphalt materials is considered an important factor contributing to the deterioration of asphalt concrete (AC) pavements. Asphalt binder aging is a combination of various complex mechanisms that affect its rheological properties causing AC to become stiffer and more brittle. As a …

Factors Affecting the Textural Properties of Pork
… measured quality traits were inconsistent across aging days and the few significant correlations (P < 0.05) showed a weak relationship (r < 0.30). Stepwise regression equations did not contain a common set of traits for all aging days. At 1 d postmortem, the prediction equation could explain 25% …

Effect of minor phase additions on the microstructure and dielectric properties of barium titanate ceramics
… modified dielectrics also show a decrease in the aging rate with increasing temperature, resulting from the internal stress condition.

Gas transport properties in polycarbonate - Influence of the cooling rate, physical aging, and orientation
… films were examined as a function of the cooling rate, physical aging, and orientation. Such conditions affect the free volume content and its size and shape distribution. Results obtained from permeation experiments were accompanied with dynamic mechanical and density measurements. The …

Melt Processable Poly(acrylonitrile)-based Precursors for Carbon Fiber Production and Advanced Polymeric Membranes for Gas Separation and Water Electrolysis Applications
… but does not show a strong dependence on shear rate. Copolymer mixtures with H2O and acetonitrile or H2O and adiponitrile were found to be suitable for melt-extrusion at 170 C with viscosities ranging from 1800-2000 Pa*s with stabilities greater than 1 hour. The modification of membranes to …
