SiC/BN/SiC-Si single-ply composites with Hi-Nicalon S™ fibres were synthesised by chemical vapour infiltration followed the liquid route. These are model representing behaviour of industrial intended to be used as structural parts in hot sections aeronautical engines. Four interphases two different degrees crystallisation and, each case, thicknesses tested. The interfacial shear stress measured...

The simultaneous flow of immiscible fluids in porous media occurs in a wide variety of applications. The equations governing these flows are inherently nonlinear, and the geometries and material properties characterizing many problems in petroleum and groundwater engineering can be quite irregular. As a result, numerical simulation often offers the only viable approach to the mathematical model...

Fusion of an interphase cell with a metaphase cell results in profound changes in the interphase chromatin that have been called "chromosome pulverization" or "premature chromosome condensation" In addition to the usual light microscopy, the nature of the changes has been investigated in the present study with electron microscopy and biochemical techniques Metaphase and interphase cells were mi...

Heat denaturation of DNA in situ, in unbroken cells, was studied in relation to the cell cycle. DNA in metaphase cells denatured at lower temperatures (8 degrees-10 degrees C lower) than DNA in interphase cells. Among interphase cells, small differences between G1, S, and G2 cells were observed at temperatures above 90 degrees C. The difference between metaphase and interphase cells increased a...

This work proposes, by a micromechanical approach, to simulate the effects of humid tropical aging on unidirectional composite (E-glass fibers/epoxy) taking into account an interphase region. An area (500 nm width) is identified AFM measurements around each fibre at initial state. During ageing this increases up 1 µm width. Numerical micro-models, using ABAQUS™, are developed predict mechanical...

BACKGROUND Telomere shortening is thought to be involved in the pathophysiology of myeloid malignancies, but telomere lengths (TL) during interphase and metaphase in hematopoietic malignancies have not been analyzed. We aimed to assess the TLs of interphase and metaphase cells of MDS and telomerase activity (TA) and to find out prognostic significances of TL and TA. METHODS The prognostic sig...

Nuclear pore complexes (NPCs) are 'supramolecular complexes' on the nuclear envelope assembled from multiple copies of approximately 30 different proteins called nucleoporins (Nups) that provide aqueous channels for nucleocytoplasmic transport during interphase. Although the structural aspects of NPCs have been characterized in detail, NPC formation and its regulation, especially during interph...

Fusing human HeLa metaphase cells with HeLa interphase cells resulted within 30 min in either of two phenomena in the resultant binucleate cell: either prophasing of the interphase nucleus or formation of a normal-appearing nuclear envelope around the metaphase chromosomes. The frequency of either occurrence was strongly dependent on environmental pH. At pH's of 6.6-8.0, prophasing predominated...

This article presents the problem of examining the interphase zone between the overlay and concrete substrate at different levels of observation. The possibility of applying available modern research methods in order to examine the interphase zone with regard to the level of observation is presented. These levels were defined in the paper. Examples of tests that show a possible approach to the ...
