background: patient radiation doses from computed tomography (ct) are increasing due to the number of ct examinations performed every day. the aim of this study was assess and evaluate patient radiation doses for adult’s common ct examinations to derive local diagnostic guidance levels for common ct examinations. materials and methods: volume and weighted computed tomography dose index (ctdivol...

The experiment was conducted using 20 male domestic pigs, which were in 2 (equal-sized) age groups: under 14 months old and over 18 months old. At least 5 ejaculates from each male were taken, and in each ejaculate, morphometric measurements of 50 spermatozoa were made. The measured parameters were head area, head length and width, and flagellum length. For each ejaculate, the basic physical tr...

ancylostoma tubaeforme was originally described as a separate species parasitizing the cat. the adults of a. tubaeforme are 7 to 12 mm long. a. tubaeforme can be differentiated from the adults of a. braziliense and a. ceylanicum by the presence of three teeth. here we describe the first re­port of a. tubaeforme in a persian young female leopard, 2-3 years old, with head and trunk length 120 cen...

OBJECTIVES Growth velocity is an important factor to monitor for appropriate child growth. This study presents the growth velocity of infants based on length, weight, and head circumference. METHODS The subjects of this study were 308 neonates (160 boys and 148 girls) born in West Azerbaijan Province of northwestern Iran who were followed from birth for 4 years. The weights and lengths of the...

We investigated the ability to perceive the metric shape of elliptical cylinders. A large number of previous studies have shown that small perspective variations (< or =10 degrees) afforded by stereovision and by head movements fail to allow accurate perception of metric shape. If space perception is affine (Koenderink & van Doom, 1991), observers are unable to compare or relate lengths in dept...

The lipochromic mosaic canary is a cage bird breed present with different coat colors, red, and yellow, this presents significant sexual dichromatism. Dichromatism in canaries explained by differential carotenoid degradation the integument, rather than sex-specific variation physiological functions such as pigment uptake or transport. Males have an intense color compared to females especially a...

The aims of this study were to identify factors associated with birthweight, birth length and head circumference for triplets, and analyze these body size parameters at birth, especially head circumference, according to gestational age. The subjects of this study were 370 mothers and their 1109 triplet children (excluding one stillborn infant) who were born between 1978 and 2002. The gestationa...

results in the first three years, the team managed the care of 812 admissions. mean age wasn 44.3 years (sd = 24.8) and mean length of hospital stay was 6.1 days (sd = 10.9). ofn these individuals, 674 attended for 6 month follow-up with 52.2% having a good outcomen on extended glasgow outcome score. patients and their relatives' feedbacks weren excellent with an average score of 4.7/5 on overa...
