OBJECTIVE.Our goal was to determine whether the third ventricle is significantly enlarged among neonates with trisomy 21, compared with infants without clinical signs of trisomy 21. This enlargement might be related to hypoplasia of the structures surrounding the third ventricle. These structures participate in cognitive development, and hypoplasia in this area may be responsible for some of th...

BACKGROUND Shoulders with recurrent anterior instability often have combined bony defects of the humeral head and glenoid. Previous studies have looked at only isolated humeral head or glenoid defects. PURPOSE/HYPOTHESIS The aim of this study was to define the relationship of combined humeral head and glenoid defects on anterior shoulder instability. Combined bony defects will lead to increas...

The centrifugal pump is one of the most important pieces energy-consuming equipment in various hydraulic engineering applications. This paper takes a low specific speed as research object. Based on method combining numerical calculation and experimental verification, influence gap drainage structure performance its internal flow field distribution were investigated. inside impeller under differ...

BACKGROUND Knowledge of the size and shape of radial head is essential for construction of radial head prosthesis. Further, the measurements of bicipital tuberosity and its angular relationship to radial head are significant in surgical techniques, like in the reconstruction of biceps tendon. Even the morphometry of the distal radius is significant in numerous clinical orthopedic situations suc...

Anthropometry, a useful method for evaluating craniofacial soft tissues, makes the quantitative description of the face possible. It also assesses the degree of disharmony and imbalance in the growth and development of the face. The aim of this study was to examine the overall common age-related changes of nasomaxillary complex of adolescent boys in northeast Iran. Three- hundred- twelve 12 to ...

A new urothripine species, Baenothrips cuneatussp. n., is described from China. This is distinguished from its congeners by the following combination of characteristics: dorsal surface of head having a wedge-shaped reticulation extending from median to the posterior margin; antennal segments VII-VIII is closely joined with a complete suture; the mesoacrotergite strongly constricted in the middl...

Experiments were undertaken to elicit the perceived effects of head-position-dependent variations in the interaural cross-correlation coefficient of a range of signals. A graphical elicitation experiment showed that the variations in the IACC strongly affected the perceived width and depth of the reverberant environment, as well as the perceived width and distance of the sound source. A verbal ...

We describe a new species of Bolitoglossa (Nanotriton) from the Sierra de Juárez and Sierra Mixe of Oaxaca, Mexico. Bolitoglossa chinantecasp. n. is distinguished from the three other species in the subgenus Nanotriton by its more robust body, by having substantial numbers of maxillary teeth and differences in relative head width, foot width, and limb length. The new species occurs in sympatry ...

Trapezoidal labyrinth weirs offer significant flow magnification for the available width of approach channel and that of the downstream chute. These types of weirs may find great utility and hence will have to be designed and provided for river linking projects. There are many factors such as head to crest height ratio, angle of side walls, vertical aspect ratio, apex width and approach and con...
