Age-Related Changes of the Human Skin Surface Microrelief

Gerontology, 2009
In the present study we describe an original semi-automated image analysis method to quantitate the changes of the geometric properties of cutaneous microrelief with age. The skin surface is composed of very fine lines intersecting each other and forming polygons.

Formation of diffractive microrelief on diamond film surface

Optics & Laser Technology, 2007
Abstract The fabrication of diamond-based optical elements for high-power CO2 lasers is of particular interest because of low optical absorption, high thermal conductivity and weak temperature dependence of the refractive index of diamond. In earlier publications, we presented the results of the implementation of ion-chemical etching technology for ...

Electromigration instability of cylindrical surface microrelief

IVMC '95. Eighth International Vacuum Microelectronics Conference. Technical Digest (Cat. No.TH8012), 2002
Instability of cylindrical conducting surface microrelief fluctuations is investigated by means of small perturbation analysis using Herring chemical potential. Unstable wave-vector domain is found and effects of microtips build up and modification are discussed from the unstable modes increments viewpoint.

Diffraction on birefringent elements with sine surface microrelief

Journal of the Society for Information Display, 2008
Abstract— Light diffraction on optically anisotropic substrates using sine surface microrelief has been calculated by using the OAGSM method. The influence of the microrelief depth and material birefringence on the diffraction intensity on the order of 0–3 is reviewed and discussed.

Design of surface microrelief with selective radiative properties

International Journal of Heat and Mass Transfer, 1994
The radiative properties of a material can be modified by its surface microrelief. We show that if the typical length of the surface roughness is smaller than a fraction of wavelength, the roughness can be treated as a homogeneous equivalent layer. Using this model and standard optimization techniques, we have developed an algorithm for the design of ...

The Spatial Dependence of Soil Surface Microrelief

2006
Surface microtopography of tilled soils is subject to spatial and temporal changes. The objective of this study was evaluate the spatial dependence of point elevation data on two cultivated soils located at Northwest Spain. Sixty-six microrelief data sets were obtained on bare plots. Each data set consisted of 4624 point elevations on a 20 mm grid. The

The Surface of the Skin — The Microrelief

1993
The surface of a body is by definition its outer part which limits it in any direction. More importantly, it is the visible covering of the body. This simple fact has considerable sociological importance, which immediately justifies the interest that researchers have taken in studying the skin for the past 10 years or so.

Photoinduced Alignment of Nematic Liquid Crystal on the Polymer Surface Microrelief

Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 2000
A polymer film surface modified by laser illumination was used as a command surface for nematic liquid crystal (LC). Azobenzene-containing polyurethanes were taken for the material of the film. A relief grating inscribed by laser illumination onto the surface of these polymers induced a reorientation of the LC director from the initial homeotropic ...
