Some Areas of Ramsar, a city in northern Iran are among the world’s wellknown inhabited areas with highest levels of natural radiation. Annual exposure levels in these areas are up to 260 mGy y‐1 and the mean exposure rate is about 10 mGy y‐1 for a population of about 2000 residents. If elevated levels of natural radiation as high as a few hundred mSv per year is detrimental to health and...

Recently, Developmental Psychology published 2 articles on the shape bias; both rejected the authors' previous proposals about the role of attentional learning in the development of a shape bias in object name learning. A. Cimpian and E. Markman (2005) did so by arguing that the shape bias does not exist but is an experimental artifact. A. E. Booth, S. R. Waxman, and Y. T. Huang (2005), in cont...

This study investigated French /y/ and /u/ produced by one native speaker (NS) and seven Japanesespeaking learners; four of them received lessons on /u/ with ultrasound visual feedback of the tongue shape and position. Acoustic measurements of 10 repetitions of six words (coronal context) are compared to those of isolated /y/ and /u/, and of the non-words /tyty/ and /tutu/, both before and afte...

Nucleocytoplasmic transport is mediated by nuclear pore complexes (NPCs), enormous protein assemblies residing in circular openings in the nuclear envelope. The NPC is modular, with transient and stable components. The stable core is essentially built from two multiprotein complexes, the Y-shaped heptameric Nup84 complex and the Nic96 complex, arranged around an eightfold axis. We present the c...

Cells of the Y-1 corticoadrenal line are: (a) functional, (b) cell cycle-arrested by adrenocorticotropic hormone (ACTH), (c) tumorigenic, and (d) c-Ki-ras overexpressing. We here report that the phorbol ester phorbol 12-myristate 13-acetate (PMA) mimics all ACTH-specific effects in Y-1 cells, namely: (a) steroid-ogenesis stimulation, (b) cell cycle block, and (c) cell shape change. In addition,...

A balanced V-shape is a polygonal region in the plane contained in the union of two crossing equal-width strips. It is delimited by two pairs of parallel rays that emanate from two points x, y, are contained in the strip boundaries, and are mirror-symmetric with respect to the line xy. The width of a balanced V-shape is the width of the strips. We first present an O(n logn) time algorithm to co...

Medial representations have been widely used for many shape analysis and processing tasks. Large and complex 3D shapes are, in this context, a challenging case. Recently, several methods have been proposed that extract point-based medial surfaces with high accuracy and computational scalability. However, the resulting medial clouds are of limited use for shape processing due to the difficulty o...

Robertsonian translocations resulting in fusions between sex chromosomes and autosomes shape karyotype evolution by creating new sex chromosomes from autosomes. These translocations can also reverse sex chromosomes back into autosomes, which is especially intriguing given the dramatic differences between autosomes and sex chromosomes. To study the genomic events following a Y chromosome reversa...

A microalgafrom Chlorarachniaceae was found in the shallow runoffs of south Tehran. Morphological and intracellular structures were studied which in accordance with the identification key (Hirakawa et al. 2011), it is found to be a new species for Iran called Amorphochlora amoebiformis (Ishida & Y. Hara) Ishida, Yabuki & S. Ota. This algahas been derived and ...
