the present study introduces, for the first time, the black tail tip three-toed jerboa from the east of the iranian plateau. this new species is different from its sympatric species, jaculus blanfordi, considering the clear black color of the hairs of its tail tip and the two large styles on the glans of the penis.

OBJECTIVES The aim of this study was to assess and compare the characteristics of commonly used initial archwires by their load deflection graphs. MATERIALS AND METHODS This study tested three wire designs namely copper nickel titanium (CNT), nickel titanium (NiTi), and multi-strand NiTi (MSNT) archwires engaged in passive self-ligating (PSL) brackets, active self-ligating (ASL) brackets or c...

the house mouse (mus musculus) is a polytypic species, with its geographic distribution largely the result of human migrations during the late glacial and holocene. this study used geometric morphometry (gm) on upper and lower molars to discriminate among the three subspecies of the house mouse present in iran. moreover cranial remains of this species were uncovered on several archaeological si...

We investigate long-period surface waves (T> 100 s) propagating across the Tibetan Plateau, based on the seismic records from a PASSCAL portable array and nearby Chinese Digital Seismic Network (CDSN) stations. Significant quasi-Love waveform anomalies, associated with fundamental Rayleigh-Love coupling, are consistently observed, suggesting that strong lateral gradients in azimuthal anisotropy...

I use photometry and spectroscopy data for 24 Type II plateau supernovae to examine their observed and physical properties. This dataset shows that these objects encompass a wide range in their observed properties (plateau luminosities, tail luminosities, and expansion velocities) and their physical parameters (explosion energies, ejected masses, initial radii, and Ni yields). Several regularit...

calomyscus elburzensis goodwin, 1938, was previously known from central and northern iran to southern and southwestern turkmenistan and northwestern afghanistan. its type locality is at altitude of 1200m elevation in the kurkhud mts., north khorasan province in northeastern iran. this study provides new evidence that its range is more extensive than thought previously and central iranian mounta...

This study aimed to investigate the association between organizational agility and knowledge sharing process in the Iran's Central Plateau Contractor Company (ICPCC). For this purpose, one main hypothesis and three subsidiary hypotheses were formulated to assess the relation between organizational agility parameters, leadership and shared identity, strong strategy, and adaptable organizational ...

one of the interdisciplinary approaches which recently had a key role in resolving of archaeological issues, especially domestication process, was archaeogenetics. caprines were domesticated in the early neolithic period and their domestication was a major part of the process that led to the invention of agriculture. since goat has had a key role in subsistence economy of human societies in dif...

the contact between major settlements in the central plateau of iran, especially in desert areas, was not possible without having a secure communication system. in this regard, designing communication networks through constructing secure roads with halfway caravansarais in desert areas, usually without secure underground and surface water supply, needed special insights and provisions. iranians...
