sepahan is a new bread wheat cultivar derived from progenies of a cross made between azadi cultivar and some high yielding and resistant to rust advanced lines. all selections were made in kelardasht and iranshahr stations and early evaluations in karaj. it was also studied in regional uniform yield trials in moderate stations including kaboutar abad. results revealed that this line is more tol...

in this paper we present the problem of designing a three level hub center network. in our network, the top level consists of a complete network where a direct link is between all central hubs.  the second and third levels consist of star networks that connect the hubs to central hubs and the demand nodes to hubs and thus to central hubs, respectively. we model this problem in an incomplete net...

The peripheral accumulation of melanosomes characteristic of wild-type mouse melanocytes is driven by a cooperative process involving long-range, bidirectional, microtubule-dependent movements coupled to capture and local movement in the actin-rich periphery by myosin Va, the product of the dilute locus. Genetic evidence suggests that Rab27a, the product of the ashen locus, functions with myosi...

According to recent proposals in formal syntax, the left-most position in the C(omplementizer)-layer is dedicated to the representation of the context of utterance (call this hypothesis LP). This idea has had little impact on semantic theories of indexicals. The reason is that indexicals are regarded, after Kaplan’s (1989) Logic of Demonstratives (LD), as directly referential and rigid. However...

The parathyroid gland of Rana tigrina is composed of closely packed epithelial cells which are arranged in whorls. A difference in the density of the parathyroída1 cells has been noticed. Cells in the center of the gland are packed compactly possessing elongated nuclei and denser cytoplasm. The cells at periphery of the gland are loosely arrenged having lightly stained cytoplasm and large spher...

Ti-6Al-4V/SUS316L dissimilar joints were manufactured by a novel solid-state joining method named “pressure-controlled joule heat forge welding”. The microstructure and mechanical properties of the systematically investigated. Both materials homogeneously deformed applying pressure corresponding to intersectional point temperature-dependent yield strength. Along joint interface, uniform hardnes...

In the nuclei of eukaryotic cells, euchromatin is located at the center, whereas heterochromatin is found at the periphery and is interspersed in the nucleoplasm. Solovei et al. (2009) now reveal that this normal pattern is reversed in the retinal rod cells of mice. This inversion might serve to maximize light transmission to photoreceptors in nocturnal mammals.

background although magnetic resonance spectroscopy (mrs) has been shown as an effective diagnostic tool in distinguishing inflammation from neoplasm in cystic brain lesions, the optimum approach in selecting the portions of lesions in mrs and the possible effects of different times of echoes (tes) remains unknown. objectives to determine the most effective te in diagnosing neoplastic lesions b...

Abstract This paper identifies changes in the center-periphery structure due to transformations capitalism since 1970. In its new configuration, not only altered relations but also exerted impact upon peripheral units that affect system itself. aims apply Ruggie’s famous critique of Waltz International Relations analyse global and show how cleavage is affecting systemic reconfiguration 21st cen...

The COVID-19 pandemic has dislocated work routines within health facilities due to new public priorities. In circumstances characterized by uncertainty and risk in the face of an unknown disease constantly changing care protocols, questions arise about how members healthcare teams have experienced these changes. We analyze experience workers a primary center periphery Buenos Aires during 2020, ...
