The stratum corneum is a complex biological material characterized by very low permeability to water and most other molecules. This material may be thought of as a 'porous medium' composed of impermeable and permeable regions. Intercellular lipid membranes in the stratum corneum are postulated to exist in a mixture of two phases: solid (i.e. impermeable) and liquid crystalline (permeable). The ...

Rockburst disasters frequently occur in deep tunnels excavated by TBM (tunnel boring machine) under complex geological conditions western China. Using FLAC3D, the characterization of a three-dimensional numerical model compound stratum tunnel is conducted, based on water transport project Shanxi Province. Then, characteristics rockburst hard and soft are revealed, energy criteria considering ro...

Twelve healthy, adult donkeys of both sexes aged between 2 and 4 years were used to evaluate the feasibility of using coronary band autografts to aid in the healing of deep dermal hoof wall injuries. Wound healing and graft take were monitored visually and evaluated histologically at different time points. Epidermal cells of the coronary papillae survived the process of hoof wall stripping. Alm...

We report patterns of dysgraphia in participants with primary progressive aphasia that can be explained by assuming disruption of one or more cognitive processes or representations in the complex process of spelling. These patterns are compared to those described in participants with focal lesions (stroke). Using structural imaging techniques, we found that damage to the left extrasylvian regio...

Study sample Power calculations were not reported. An overall sample of 3,416 patients was considered. The number of patients included in each treatment arm was not reported. The patients were stratified into three approximately equal groups and were allocated to the FP or SFC arms of the trial. The three strata related to the patients' use of inhaled corticosteroids for 6-months prior to scree...

This paper identifies the application of capability concept (Sen, 2000) as a globally viable business strategy for the coming age which can be used to expand markets into to all levels of the social stratum. ‘Capability’ development is proposed as a way to propel business and expand markets to all levels of the social stratum. The article describes how Information and Communication Technology w...

A simple and practicable algorithm for constructing stratum boundaries in such a way that the coefficients of variation are equal in each stratum is derived for positively skewed populations. The new algorithm is shown to compare favourably with the cumulative root frequency method (Dalenius and Hodges 1957) and the Lavallée and Hidiroglou (1988) approximation method for estimating the optimum ...

1. Introduction and Motivation The International Price Program (IPP) publishes monthly price indexes which measure the average change over time in prices of internationally traded products and services. IPP's sampling methodology supports its published merchandise price indexes by attempting to maintain a minimum number of items over the two year life cycle 1 of each published stratum. Retentio...
