One of the common causes a heart attack is fibrillation, condition that an irregular and often abnormally fast rate. There scientific evidence survival rate sudden cardiac arrest patients who are rescued with cardiopulmonary resuscitation (CPR) use automated external defibrillator (AED) significantly increased. Despite recommendation defibrillators should be installed in workplace, along proper...

Security as one of the basic human needs has a special place in relaxation, comfort and spiritual needs provision. For this reason, security is always of managers, planners, architects and urban designers' interest. Solutions and strategies of security provision have been fundamentally changed following prevailing change of housing architecture patterns from homes to residential complexes and h...

Decreasing qualitative aspects of residential environments is a real problem in recent public housing of Kerman. This article is concentrated on surveying the impact of in-between spaces on residential environments quality (REQ), to evaluate different kinds of it and to determine interrelation of two main components: residents individual characteristics and characteristics of in-between spaces....

We study the evolution of stable D-branes of C/Zn and twisted circle theories in the process of closed string tachyon condensation. We interpret the fractional branes in these backgrounds as type II branes wrapping (‘blown up’) cycles, and trace the evolution of the corresponding cycles under tachyon condensation. We also study RG flows of the corresponding N = 2 boundary conformal field theori...

Let p > 2 be a prime, The group ring RG is calculated nearly up to Morita equivalence: The projections of RG into the simple components of KG are given explicitly and the endomorphism rings and homomorphism bimodules between the projective indecomposable RG-lattices are described.

We study boundary Green’s functions for spacetimes with non-relativistic scaling symmetry. For this class of backgrounds, scalar modes with large transverse momentum, or equivalently low frequency, have an exponentially suppressed imprint on the boundary. We investigate the effect of these modes on holographic two-point functions. We find that the boundary Green’s function is generically insens...

We discuss the interplay between IR and UV divergences in vacuum configurations with open and unoriented strings. We establish a general one-to-one correspondence between anomalies and R-R tadpoles associated to sectors with non-trivial Witten index. The result does not require any supersymmetry to be preserved by the configuration. Under very mild conditions of supersymmetry, a similar corresp...

it is not long time that residential complexes have been built in tehran. although during thistime, always influenced by some factors, configuration of the residential complexes has undergone fluctuations, rateof which has been very fast especially in recent decades considering the fundamental changes that have emerged in the housing debate. turning housing into an investment commodity. residen...

Abstract The importance of forests for their functions other than timber and wood production has dramatically increased in the last decades with awareness risks deriving from deforestation acknowledgment great amount goods benefits provide. Consequently, national forest inventories have widened objectives nowadays include variables related to environmental aspects. Among these aspects, biodiver...
