Sensitive skin: correlation with skin surface microrelief appearance

Skin Research and Technology, 2006
Background/purpose: Sensitive skin is a condition associated with reduced tolerance to environmental factors and/or the application of topical products, such as cosmetics. Its pathophysiology has not been fully elucidated and few data are available on its prevalence.

Photovoltaic properties of microrelief GaAs structures

Applied Solar Energy, 2008
The formation of microrelief on the front surface of AlGaAs/GaAs cells is proposed. The technology of formation of diffusion p-n junctions has been developed and AlGaAs/GaAs-based photosensitive structures have been prepared. Their spectral characteristics are studied.

Skin microrelief profiles as a cutaneous aging index

Microscopy, 2016
An objective measurement of cutaneous topographical information is important for quantifying the degree of skin aging. Our aim was to improve methods for measuring microrelief patterns using a three-dimensional analysis based on silicone replicas and scanning electron microscope (SEM).

MICRORELIEF METER FOR FIELD TOPOGRAPHY MEASUREMENTS

Transactions of the ASAE, 2001
The design and evaluation of an automated, non–contact microrelief meter for measuring soil surface elevations under field conditions are presented. Key factors in the design of the meter are measurement accuracy, data–collection speed, and portability. Surface elevations are measured by determining the location of a laser line using image–processing

Microrelief structures for anti-counterfeiting applications

Microelectronic Engineering, 2003
Microrelief surfaces including grating structures, greytone/micrographic features and microramps have been fabricated with depth features of up to 30 µm. Grey scale lithography has been used to produce the microstructures by a single UV exposure into a layer of thick resist.

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.

Microrelief, rainfall and cover effects on infiltration

Soil and Tillage Research, 1990
Abstract Field infiltration behavior of a fine loamy mixed mesic, Typic Haplaquoll, was related to indices of surface microrelief and rainfall energy using simulated rainfall and ponded water. Infiltration of simulated rainfall was controlled primarily by a surface crust.

Microrelief on Arctic Sea Floor

AAPG Bulletin, 1954
The upper continental slope in the Arctic Ocean off Alaska and northwestern Canada is characterized by a series of low mounds and troughs. These features are found only between the edge of the shelf and the 200-fathom isobath on the slope, and on the sides of two shelf valleys.

Microrelief of the skin using a light transmission method

Archives of Dermatological Research, 2000
The recently developed Skin Visiometer, based on light transmission through blue-coloured silicone replicas, was used to study skin microrelief. Calibrated metal plates displaying lines with depths between 6 and 361 microns, were used to determine the accuracy, sensitivity and reproducibility of the technique as well as the parameters of importance ...

Longitudinal study of skin aging: from microrelief to wrinkles

Skin Research and Technology, 2011
Aim: To study the changes in skin microrelief and periocular wrinkles during the aging process.Methods: Replicas of the crow's feet area of volunteers were recorded in 1987 and 2008 and observed comparatively. Characteristic features were quantified by image analysis.Results: Observation shows that some microrelief features disappear and even merge ...
