BACKGROUND A prototype anthropomorphic head and neck phantom has been designed to simulate the adult head and neck anatomy including some internal organs and tissues of interest, such as thyroid gland and sentinel lymph nodes (SLNs). The design of the head and neck phantom includes an inner jig holding the simulated SLNs and thyroid gland. The thyroid gland structure was manufactured using thre...

UNLABELLED To analyze anatomical variations of the proximal end of femur that could cause a femoroacetabular impact. METHODS 199 skeletically mature anatomical specimens of femurs were used. The femurs were measured in order to determine the anteversion angle of the femoral neck, neckshaft angle, sphericity of the femoral head at anteroposterior and superoinferior, angle between epiphysis and...

The use of ultrasonography has significantly improved the evaluation of fetal growth and development and has permitted prenatal diagnosis of a variety of congenital malformations.Campbell et al in (1968) studied fetal cephalometry in the second trimester and determined that the fetal head can be measured from 13 week of pregnancy2. BinholzJ.C(1982) studied the new born cerebellar size both in f...

Yield and relationships among head traits were recorded in order to better understand the effects of planting date and cultivar selection on crop quality characteristics and to help increase the efficiency of cultivar development, evaluation, and selection. A total of seven cultivars of fresh market-type cabbage (Brassica oleracea L., Capitata Group) were planted in May and June of 1999 and 200...

This study was conducted to examine morphometric and meristic characteristics alongside pigmentation patterns of bream larvae, Abramis brama orientalis, in four stages of larval development. Morphological characters including total length (TL), standard length (SL), notochord length (NL), head length (HL), head depth (HD), eye diameter (ED) and mouth width (MW) were examined from hatching time ...

The characterization of flow through Pelton hydro turbines allows the optimization their operation and maximization energy performance. in injector free jet area (the from outlet surface to runner bucket inlet surface) is influenced by several parameters: geometry components (nozzle spear), opening, turbine head. parameters (velocity distribution, pressure spread) are reflected efficiency. rese...

A key assumption of ethology is that characteristic behavior of organisms is that which brings some benefit, or in the jargon, “increased fitness,” to them or their kin. Innate (geneticallydetermined) behavior has this characteristic, e.g., the broken-wing feint of different species of ground-nesting birds which draws prey away from the nest of chicks. (This is not to deny that characteristic b...

Implantation of a large-diameter femoral head prosthesis with a metal-on-metal bearing surface reduces the risk of dislocation, increases the range of movement, minimises the risk of impingement and, in theory, results in little wear. Between February 2004 and March 2007 we implanted 100 consecutive total hip replacements with a metal-on-metal bearing and a large femoral head into 92 patients. ...

PURPOSE To evaluate the performance of the Nidek MK-2000 and the LSK Carriazo Barraquer microkeratomes in the creation of corneal flaps for laser in situ keratomileusis (LASLK). METHODS A prospective randomized study of 55 eyes of 30 patients who underwent LASLK was performed. Twelve corneal flaps were created hy the Nidek MK-2000 microkeratome (160-/«n head), 30 corneal flaps by the Carriazo...
