in this paper, we prove that every metric line in the poincare ball model of hyperbolic geometry is exactly a classical line of itself. we also proved nonexistence of periodic lines in the poincare ball model of hyperbolic geometry.

Fungal pores feel the pull S teinberg et al. report that fungi use motor proteins to distribute their nuclear pores around the nuclear envelope. In animal cells, the nuclear lamina holds the nuclear pores in place, ensuring that they are evenly spaced. The lamina prevents nuclear pores from clustering, promoting import of cargoes through the pores and helping to organize the chromosomes, which ...

Nuclear magnetic resonance is widely used as a probe of pore geometry and fluid composition in well logging. One of the critical assumptions often made is that the diffusion of fluid molecules is sufficiently fast to warrant the condition for direct mapping between the surfaceenhanced relaxation rate and the pore geometry. In pores satisfying such a condition, but having a significant spatial v...

Iranian traditional homes are unique architecture samples with an Iranian essence. These homes are a suitable subject for research in Iranian architecture. These homes can provide answers to some question that we have these days, like using geometry in architectural design of this home.  Iranian traditional architects have been interested in geometry and been using in almost all parts of homes....

scale insect specimens collected on hordeum sp. (poaceae), dated 24. v. 2003 in khorram abad, lorestan province were identified as exaeretopus tritici williams. this species, which the genus and species is newly recorded from iran, is related to e. harpazi ben-dov, differing mainly in the number of the stigmatic setae and extension of paraopercular pores.

A In this article the role of geometry and its interaction with imagination in creating the unique architectural will be explained. From long time ago philosophers and prominents have referred to important role that imagination and geometry have in the creation of universe. All over the universe, the emergence of geometry at beginning of creation is undeniable. Geometry with its manifestation a...

Gypsophila with approximately 150 speciesrepresents the fourth largest genus of Caryophyllaceae and the second genus of tribe Caryophylleae. Iran is the second main center of Gypsophila diversity with 38 species in the world. Considering Gypsophila as one of the most polymorphic genus of the family andalmost half of its taxa distributed in Iran as endemic, thus makes it as a significant genus f...
