A state of the art of 3D surface characterization techniques in the automotive and steel industries is presented, and links with mathematical morphology are highlighted. A surface topography decomposition method is described. It decomposes a surface into three elements: reference surface (waviness and form), superficial roughness (related to friction and wear) and valleys (related to lubricant ...

Based on a set of evolutionary calculations for thermally pulsating post-AGBmodelswe introduce a robustmethod to measure FGSge’s mass which was found to be 0.61M . The corresponding evolutionary timescale is consistent with the expansion age of the planetary nebula. Assuming that FGSge’s surface was already enriched with heavy elements on the AGB we propose that during the central-star evolutio...

superficial siderosis (ss) is a rare disease which affects people in all ages and both sexes, but three times more in men. pathological etiology is deposition of hemosiderin (a product of the breakdown of blood) in leptomeninges, subpial layer, ependymal surface and other parts of central nervous system (cns) and typically leads to neurological dysfunction and progressive irreversible signs and...

Electron micrographs (EMs) of central nervous tissue perfused with glutaraldehyde and post-fixed with osmium tetroxide exhibit more extracellular space in superficial than in deep regions of the brain. It was postulated that this is due to the availability to the surface tissue of the cerebrospinal fluid in the subarachnoidal space. It was assumed that in addition to the extracellular material ...

Objective This study aimed to compare standard saline lavage to combination saline and high-pressure carbon dioxide (CO2) lavage in removing marrow elements from osteochondral allografts. Design Six fresh hemicondyles were obtained. Three osteochondral allograft plugs (15-mm diameter, 6-mm depth) were harvested from each hemicondyle and randomized to 1 of 3 treatment arms: A, no lavage; B, 1 L ...

background and purpose: candida species are the most common organisms involved in superficial fungal infections, worldwide. although econazole is among the most frequently used topical formulations for the treatment of candidiasis, no information is available regarding the susceptibility profiles of candida species in iran. materials and methods: in vitro susceptibility of 100 clinical candida ...

In the Mekong River delta and its associated coastal zone trace elements concentrations (Cd, Cu, Ni and Pb) were measured in the dissolved phase (DP) during dry (March 1997) and wet (October 1997) seasons. As, Co, Cr, Ni, Pb, and Al were also measured in suspended matter (SM) and total and organic carbon, trace elements (Cd, Cr, Cu, Hg, Mn, Ni, Pb, Zn) and macro elements in superficial sediment...

A new version of the popular software PISA for the analysis of macromolecular interfaces and identification of biological assemblies (complexes) from macromolecular crystal structures is presented. The new web server jsPISA has a substantially improved user interface, based on modern JavaScript technologies, and also new elements of analysis: assembly stock and interaction radar. The new elemen...
