We introduce a new covering property, defined in terms of order types of sequences of open sets, rather than in terms of cardinalities. The most general form depends on two ordinal parameters. Ordinal compactness turns out to be a much more varied notion than cardinal compactness.

Background Although sarcopenia has been recognized as a predictor of mortality in elderly patients with hip fracture, the association of thigh fat and muscle with cardiovascular (CV) outcome remains unclear. We examined the impact of computed tomography (

Evaluation of concrete mechanical strength through porosity
The increasing on voids or pores in any material - if the rest of characteristics remains equal -always causes a decrease in their mechanical strength since the ratio volume/resistant mass is lower Following all these fact a well known conclusion rises ...

O uso intensivo do solo, aliado a condições inadequadas de manejo, concorre para a deterioração de suas propriedades físicas e isso se deve, principalmente, às modificações em sua estrutura.

Compactness in the endograph uniformity
Given a uniform space (X,U), we denote by F*(X) to the family of fuzzy sets u in (X,U) such that u is normal and upper semicontinuous. Let UE be the endograph uniformity on F*(X).

Monocular reconstruction of shapes of natural objects from orthographic and perspective images
Human subjects were tested in perception of shapes of 3D objects. The subjects reconstructed 3D shapes by viewing orthographic and perspective images.

We initiate a study of topological orthoalgebras (TOAs), concentrating on the compact case. Examples of TOAs include topological orthomodular lattices, and also the projection lattice of a Hilbert space. As the latter example illustrates, a lattice-ordered TOA need not be a topological lattice.

The coating was treated by laser with different power. Microstructures of two kinds of coatings were examined by scanning electron microscopy(SEM). The phase of two kinds of coatings was detected by X-ray diffraction(XRD).

Compactness of the Complex Green Operator on C1 Pseudoconvex Boundaries in Stein Manifolds
We study compactness for the complex Green operator Gq associated with the Kohn Laplacian □b on boundaries of pseudoconvex domains in Stein manifolds. Let Ω⋐X be a bounded pseudoconvex domain in a Stein manifold X of complex dimension n with C1 boundary.
