Longterm exposure to ultraviolet radiation (UVR) and air pollution (PM2.5.) significantly contribute extrinsic skin aging. More recently, global warming has been recognized as an environmental threat human health. However, its effects on in general aging particular, are poorly understood. We examined the association between long-term mean temperature (Tmean) environmentally-induced phenotypes. ...

© Appl. Rheol. 20 (2010) 63293 DOI: 10.3933/ApplRheol-20-63293 Abstract: Bitumen is undoubtedly the most important material in the construction and rehabilitation of flexible road pavements. By increasing the temperature, bitumen changes from brittle solid, to viscoelastic solid and finally to Newtonian fluid. The rheological characteristics of bitumen also vary greatly due to aging, which is a...

Atom-probe tomography, transmission electron-microscopy, x-ray diffraction, and firstprinciples calculations were employed to study the (i) compositional evolution of GPII-zones and "!-precipitates, and (ii) solute segregation at !-Al/"!-interfaces in Al-4 wt. % Cu alloys. GPII zones are observed for aging at 438 K for 8 h, whereas higher aging temperatures, 463 K for 8 h and 533 K for 4 h, rev...

This paper addresses the ways in which heat loss effector functions change with maturation and aging, using data obtained in our laboratory. Prepubertal children have an underdeveloped sweat function compared with young adults; this is compensated by a greater surface area-to-mass ratio and relatively greater heat loss from cutaneous vasodilation on the head and trunk when the air temperature i...

We study the aging of the two-dimensional fully-frustrated Ising and three-state Potts models by means of Monte Carlo simulations. The system is initially prepared at infinite temperature and then quenched either at its critical temperature or in the low-temperature phase for the three-state Potts model. Autocorrelation and response functions are shown to satisfy the scaling behavior conjecture...

Uniform crystalline colloidal cholesterol particles of narrow size distribution were obtained by precipitation. The method consisted of adding a miscible non-solvent (water) into cholesterol solutions of different alcohols and acetone, without any additives. The properties of the resulting particles depended in a sensitive way on the concentration of all reactants, temperature, pH, ionic streng...

This paper presents accurate data for the physical aging of organic glasses just below the glass transition probed by monitoring the following quantities after temperature up and down jumps: the shear-mechanical resonance frequency (∼360 kHz), the dielectric loss at 1 Hz, the real part of the dielectric constant at 10 kHz, and the loss-peak frequency of the dielectric beta process (∼10 kHz). Th...
