Introduction: The most common type of velopharyngeal valve (VPV) closure is a matter of controversy.The aim of this study was to estimate the most common type of VPV closure, including identification of the type and grade of VPV closure among Egyptian children.  Materials and Methods: This study included patients who were candidates for adenotonsillectomy. In these cases, video-nasoendoscopy an...

Cosmogenic aluminum-26 and beryllium-10 burial dates of low-lying fossiliferous breccia in the caves at Sterkfontein, South Africa, show that associated hominid fossils accumulated in the Lower Pliocene. These dates indicate that the skeleton StW 573 and newly discovered specimens from Jacovec Cavern have much the same age: approximately 4 million years. These specimens are thus of an age simil...

In this paper, the notion of closure operators of matroids  is generalized to fuzzy setting  which is called $M$-fuzzifying closure operators, and some properties of $M$-fuzzifying closure operators are discussed. The $M$-fuzzifying matroid induced by an $M$-fuzzifying closure operator can induce an $M$-fuzzifying closure operator. Finally, the characterizations of $M$-fuzzifying acyclic matroi...

Expanded Polystyrene (EPS) is a lightweight, malleable, adjustable strength material with good cushioning properties. This paper introduces the concept of diameter-thickness ratio and high-thickness to analyze impact force duration data tests different thicknesses EPS plates sand cushion layers under environments, which shows that within range thickness can be withstood by structure shed cavern...

Results of numerical simulations of momentum transfer for a highly shear-thinning fluid (0.2% Carbopol) in a stirred tank equipped with a Prochem Maxflo T type impeller are presented. The simulation results were validated using LDA data and both tangential and axial force measurements in the laminar and early transitional flow range. A good agreement between the predicted and experimental resul...

allows a measurement which is independent of an absolute ux or exposure calculation. Soudan 2 is an iron calorimeter with di erent experimental systematics from the water Cherenkov detectors and with a di erent geometry and detection technique from from the Frejus experiment. A large veto shield placed against the cavern wall allows the identi cation of particles entering the detector from the ...

CAVERN, the CAVE Research Network, is an alliance of industrial and research institutions equipped with CAVE s, ImmersaDesks, and high-performance computing resources all interconnected by high-speed networks to support collaboration in design, training, scientific visualization, and computational steering, in virtual reality. CAVERNsoft is the common collaborative software architecture for CAV...
