Surface properties of regenerating limb cells: Evidence for gradation along the proximodistal axis
Differentiation, 1984Abstract When two limb regeneration blastemas are cocultured in vitro, proximal blastemas surround distal ones in a position-related hierarchy, whereas blastemas from the same level exhibit no engulfment behavior. Regenerative processes dependent on positional information can be interpreted in terms of differences in surface adhesive properties of ...

Performance-Based Design Method for Gradation and Plasticity of Granular Road Surface Materials
Transportation Research Record: Journal of the Transportation Research Board, 2018Granular-surfaced roads frequently experience severe surface damage and degradation, which adversely affects traffic safety and significantly increases maintenance costs. The importance of the gradation and plasticity of granular-surfaced road materials have long been recognized.

Photometric stereo with gradated extended sources for recovery of specular surfaces
Journal of the Optical Society of America A, 2010A photometric stereo technique is proposed that uses four extended sources and specular reflection to estimate surface topography. It is shown that if the intensity of incident light is weighted according to its zenith angle, then the radiance of surface facets will vary linearly with their slope.

X-ray photoelectron spectroscopy (XPS) has been used for analyzing the surface composition of polyol process-derived Fe30Co70, Fe50Co50, and Fe70Co30 alloy nanoparticles with diameters 50, 100 and 150 nm, respectively. These Fe-Co alloy particles have high oxidation resistance in the atmospheric environment even though their particle size is so small ...

Abstract Roadway friction is one of the most important features for road safety. Many procedures, tests, and tools have been used widely to measure surface frictional properties of flexible pavements. The main objective of this study is to evaluate the surface characteristics of Superpave laboratory-prepared Hot Mix Asphalt (HMA) specimens made of ...

Although filling ceramic powders into the insulative polymer layer has long been realized as an effective strategy to elevate the heat dissipation capability and service life of copper clad laminates (CCLs), the weak interfacial bonding between inorganic filler and organic matrix and the discontinuous thermal conductive network have hindered such ...

Based on the general review of the grading characteristics for traditional asphalt mix, this paper summarizes a relevant test on nine groups of asphalt mix, including three nominal maximum sizes (4.75mm, 9.5mm and 13.2mm) and three design grading types (close to the upper, median and lower limit of the grading range recommended by specification).

Langmuir, 2014
Poly(fluoroalkyl acrylate)s with long perfluorooctyl pendant groups have been found to lead to the release of biopersistent perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS). Those with no more than six perfluorinated carbons in pedant groups do not cause such problems.

The aggregate gradation of asphalt concrete for a road pavement is a critical element since it influences its strength and mechanical properties, and also has a major role on the thermal properties. An experimental study was set up to develop a multi-criteria optimization of AC12 dense-graded asphalt mixtures designed for asphalt solar collector ...
