A remark on T-duality and quantum volumes of zero-brane moduli spaces. T-duality (Fourier-Mukai duality) and properties of classical instanton moduli spaces can be used to deduce some properties of α ′-corrected moduli spaces of branes for Type IIA string theory compactified on K3 or T 4. Some interesting differences between the two compactifications are exhibited.

This paper will discuss about the role of the geopolitical location of South Africa in the development of movie and the cinema industry in this country. Despite of bringing ci-nema to South Africa by white Europeans, but the development of this phenomenon is mostly due to the geopolitical position of this country. It is interesting to know that ci-nema reached Africa in much the same time as it...

We construct compact polyhedra with triangular faces whose links are generalized 3-gons. They are interesting compact spaces covered by Euclidean buildings of type A2. Those spaces give us twodimensional subshifts, which can be used to construct some C-algebras.

What is a combinatorial game? The usual definition is a game in which (i) there are two players moving alternately; (ii) there are no chance devices and both players have perfect information; (iii) the rules are such that the game must eventually end; and (iv) there are no draws, and the winner is determined by who moves last. In this section, two master expositors lead us through many examples...

Together with spaces of constant sectional curvature and products of a real line with a manifold of constant curvature, the socalled Egorov spaces and ε-spaces exhaust the class of n-dimensional Lorentzian manifolds admitting a group of isometries of dimension at least 1 2n(n − 1) + 1, for almost all values of n [Patrangenaru V., Geom. Dedicata 102 (2003), 25–33]. We shall prove that the curvat...

The city is alive with dynamic systems, where parks and urban green spaces have high strategic importance which help to improve living conditions. Urban parks are used as visual landscape with so many benefits such as reducing stress, reducing air pollution and producing oxygen, creating opportunities for people to participate in physical activities, optimal environment for children and decreas...

Experts have found that natural environment could have positive impacts on patient’s treatment process. The impact of natural environment on mental state and lowering the stress level of the patients is undeniable. In this study, the impacts of natural environment on patient women in Tehran general hospitals were investigated. After conducting a topical study of the issue on hand, using fiel...
