Model approach is used to obtain expression for the thermoelectric power factor sigma S 2 (sigma --- static conductivity, Seebeck coefficient), characterized monoatomic 2D layer of IV group elements, placed between two slabs, formed by hexagonal layers III-V com-pounds. The h-BN/graphene/h-BN structure thoroughly studied and dependence value on chemical potential μ examined. analytical estimate...
today as the land-filling of solid wastes without taking into consideration the environmental issues would threaten the land greatly, the selection of an appropriate site for hygiene disposal of the wastes is a necessity. analytic hierarchy process (ahp) is one of the most frequently used methods of multiple criteria choices. in site selection of an optimum place fro landfill in the city of bon...
Skin burns are common skin injuries that can result from exposure to various sources of heat by which, depending on the cause, different degrees of burns are generated. In restoration of superficial burns by re-epithelialization, the skin is rebuilt, but the skin color is different than the healthy tissue. Keratinocytes represent the major cells of the epidermis. These cells are sourced from ec...
We construct new TW-sequences, weighing matrices and orthogonal designs using near-Yang sequences. In particular we construct new OD
asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...
The article discusses the presentation of features cerebellar remodeling after traumatic brain injury (TBI) in highlands. experiment was carried out on 106 outbred male rats weighing 210-290 g compliance with rules laboratory practice. In high-altitude conditions, contrast to low-altitude significant changes occur cerebellum, namely, membrane potential cells, ectopia Purkinje pronounced molecul...
We verify the skew weighing matrix conjecture for orders 2t.7, t ~ 3 a positive integer, by showing that orthogonal (1, k) exist for all t k = 0, 1, .... , 2.7 1 in order 2t.7 We discuss the construction of orthogonal designs using circulant matrices. In particular we construct designs in orders 20 and 28. The weighing matrix conjecture is verified for order 60. Disciplines Physical Sciences an...
We employ theoretical and computational techniques to construct new weighing matrices constructed from two circulants. In particular, we construct W (148, 144), W (152, 144), W (156, 144) which are listed as open in the second edition of the Handbook of Combinatorial Designs. We also fill a missing entry in Strassler’s table with answer ”YES”, by constructing a circulant weighing matrix of orde...
Crystalline surface layer proteins (S-layer proteins) have considerable potential for the crystalline arrays in biotechnology, biomimetics and nonlife applications, including areas such as microelectronics and molecular nanotechnology. The extensive application potential of surface layers in nanobiotechnology is according to the particular inherent attributes of the single molecular arrays cons...
Land subsidence due to groundwater resources extraction is one of the abundance events occurred in Iran. If it is not properly managed, this phenomenon can cause irreparable damage to the affected areas. Population growth and agricultural technology have also led to overexploitation of the groundwater resources in some parts of Iran. The rate of land subsidence due to overexploitation of the g...
