We present a new measurement of the deuterium-to-hydrogen ratio (D/H) in the Lyman limit absorption system at z = 3.572 towards Q1937–1009. Tytler, Fan & Burles (1996; hereafter TFB) made the first extragalactic detection of deuterium in this absorption system, which remains the best location for a high accuracy measurement of primordial D/H. Their detailed analysis of Keck spectra gave a low v...

Duodenal samples were taken from similar locations in six cats, processed, stained, and examined via light microscope. There were no prominent circular folds (plicae circulares) or stratum compactum (lamina subglandularis). The 1072 microns x 201 microns villi were covered by 46 microns high columnar epitheliocytes proximally which decreased in height (41 microns) distally and displayed a 1.1-1...

the bedriaga's plate-tailed gecko, teratoscincus bedriagai, nikolsky, 1900 is distributed in the northern and eastern deserts of sistan, iran and the desert regions of southern afghanistan. in this research, the male reproductive cycle of this lizard has been studied from 5 april to 5 august, 2013. totally, 40 adult males were collected by hand at midnight from four adjacent stations in damghan...

. to investigate the effect of anisometropic and strabismic amblyopia on the nerve fiber layer thickness. this cross-sectional study was done on 54 amblyopic subjects, equally in both strabismic and anisometropic groups. the thickness otonerve fiber layer measured in superior, inferior, nasal, temporal quadrants and as a whole in both eyes of both groups. the means of thickness were compared in...

2 microns DNA isolated from industrial Saccharomyces cerevisiae yeasts exhibited extensive restriction fragment length polymorphisms. At least five 2 microns species were identified from eleven [cir+] strains. Southern hybridization mapped restriction fragment length polymorphisms at STB, a cis-acting locus essential for plasmid partitioning. Some 2 microns variants (e.g., 4110-2 microns and 41...

BACKGROUND Violence against women is one of the major public health problems in both developed and developing worlds. The aim of this study was to investigate the prevalence of current (occurred in one year preceding the survey) domestic violence and socio-demographic factors associated with domestic violence against women. METHODS This was a cross sectional household survey (face to face int...
