We introduce topological definitions of expansivity, shadowing, and chain recurrence for homeomorphisms. They generalize the usual definitions for metric spaces. We prove various theorems about topologically Anosov homeomorphisms (maps that are expansive and have the shadowing property) on noncompact and non-metrizable spaces that generalize theorems for such homeomorphisms on compact metric sp...

Most thin-film photovoltaic modules are constructed on soda-lime glass (SLG) substrates containing alkali oxides, such as Na2O. Na may diffuse from SLG into a module's active layers through P1 lines, an area between constituent cells where the substrate-side charge transport layer (CTL) is in direct contact with SLG. diffusion known to cause several important effects II–VI and chalcogenide sola...

The structure of the condensed bromocadmate anions in [C(NH2)3]Cd2Br5 (1) and [H2NNH3]3CdBr5 (2) were studied at room temperature by X-ray diffraction. (1) crystallizes with double-chains bridged by Br atoms (orthorhombic, Pmmn, Z = 2, a = 1394.0(5), b = 394.5(1), c = 1086.9(5) pm). This chain structure was not described previously. (1) shows three 8 'Br NQR lines at temperatures between 77 and...

The concept of β∗-homeomorphisms is introduced and investigated by Palanimani [13] earlier. In the present paper we investigate some more properties of β∗-homeomorphisms and also investigate contra β∗-homeomorphisms.

Brassinosteroids (BRs) and Gibberellins (GAs) are two classes of plant hormones affecting plant height (PHT). Thus, manipulation of BR and GA levels or signaling enables optimization of crop grain and biomass yields. We established backcross (BC) families, selected for increased PHT, in two elite maize inbred backgrounds. Various exotic accessions used in the germplasm enhancement in maize proj...

We give an equivalent condition for the existence of a semi-conjugacy to an irrational rotation for conservative homeomorphisms of the two-torus. This leads to an analogue of Poincaré's classification of circle homeomorphisms for conservative toral homeomor-phisms with unique rotation vector and a certain bounded mean motion property. For minimal toral homeomorphisms, the result extends to arbi...

Background: In plant breeding program to produce hybrid varieties, pair of male sterile and restorer fertility lines are required. Differentiation of lines possessing restorer fertility allele from the lines lacking it remove the need for the progeny test, and thus reducing the time and the cost in the hybrid production procedure. Canola breeding program in Iran has concentrate...

Structural steel sections are mainly used in beams and columns of building frames. Iran National Steel IndustrialGroup is among the oldest and largest producers of beams in Iran. It has two beam production lines, namely Line630 and Line 650. In this study, the mechanical properties of manufactured beams in these production lines werecompared. Based on the t-test results, the e...

Using symplectic topology and the Radon transform, we prove that smooth 4-dimensional projective planes are diffeomorphic to CP. We define the notion of a plane curve in a smooth projective plane, show that plane curves in high dimensional regular planes are lines, prove that homeomorphisms preserving plane curves are smooth collineations, and prove a variety of results analogous to the theory ...

the cytotoxic activity of ethanolic extracts of thymus vulgaris, thuja orientalis and achillea millefolium was investigated on various growing tumor cell lines. mtt colorimetric assay was used for measuring the inhibition of cell proliferation. all of the three extracts showed a relatively dose-dependent inhibition of proliferation of human breast cancer (sk-br-3, mda-mb-435) and leukemia (u937...
