ObjectiveTo compare transabdominal (TA) and transrectal (TR) ultrasonography of the prostate gland. DesignExperimental study. Animals10 intact male dogs that required euthanasia for reasons other than prostatic disease. ProceduresProstatic length (L), width (W) and height (H) were measured in T A (L1, W1 and H1) and TR (L2 and H2) ultrasonography. Prostatic volume was calculated using the formu...

it’s obvious that road safety is causing large problems and costs in iran with an enormous impact on the well-being of people, economy and productivity. the yearly number of fatalities and injuries is still unchanged. motor vehicle injuries lead the list of injury deaths at the all ages during childhood and adolescence, even in children under 1 yrs of age. understanding the actual of child road...

Craniosynostoses are recognized as a group of birth defects that impair the skull structures by early closure of one or more sutures, causing an abnormal cranial shape. Among the "simple" craniosynostoses, (a single closed suture) the most common is scaphocephaly. The 3D CT scan is the most relevant and rapid diagnostic test. The authors present the personal experience of 98 scaphocephaly cases...

in this paper the numerical simulation and operation comparison of two sizes of air gun pellets with 4.5 and 5.5 mm calibers is performed. these pellets affected by drag force and are encountered to continuous velocity variations and experience an unsteady flow. in order to solve this problem numerically, the navier- stokes equations in an unsteady compressible turbulent flow with the dynamical...

The notion that apparent sizes are perceived relative to the size of one's body is supported through the discovery of a new visual illusion. When graspable objects are magnified by magnifying goggles, they appear to shrink back to near-normal size when one's hand (also magnified) is placed next to them. When objects are "minified" by minifying goggles, the opposite occurs. The rescaling effect ...

In many cases, each network imposes a maximum permitted packet size called payload size. Hence, some protocols such as TCP specify a message segmentation function allows a sender to divide a single message greater than the payload size into multiple packets. In this report, we derive an analytical form of a covariance of a packet size sequence for an environment where message segmentations happ...

OBJECTIVE Larger food portion sizes lead to increased energy intake levels and might contribute to the current obesity epidemic. Only a very limited number of studies are available on the actual development of food portion sizes during past decades. The present study aims to reveal trends in portion sizes of some high-energy-dense food products during recent decades in The Netherlands. DESIGN...

OBJECTIVE To identify and compare suggested food portion sizes in UK schemes. DESIGN The study collated and compared suggested portion sizes from selected UK schemes intended both for general advice and weight-loss advice. SETTING Portion size schemes were included if they were relevant to the UK, provided actual portion size information, were intended for adults and were obtainable from th...

To meet the increasing demand for patterning smaller feature sizes, a lithography technique is required with the ability to pattern sub-20 nm features. While top-down photolithography is approaching its limit in the continued drive to meet Moore's law, the use of directed self-assembly (DSA) of block copolymers (BCPs) offers a promising route to meet this challenge in achieving nanometre featur...

For species with low genetic diversity, typing using the differences in PCR fragment length resulting from variations in numbers of short tandem repeats has been shown to provide a high level of discrimination. This technique has been called multilocus microsatellite typing (MLMT) or multiple-locus variable-number tandem repeat analysis, and studies usually employ genetic or sequence analyzers ...
