<p style='text-indent:20px;'>We present a survey of recent results on gravity water flows satisfying the three-dimensional wave problem with constant (non-vanishing) vorticity vector. The main focus is to show that flow non-vanishing has two-dimensional character in spite equations. More precisely, does not change one two horizontal directions. Passing rotating frame, and introducing thus...

Background & Aims: Sonography has enjoyed much attention as a noninvasive diagnostic tool for carpal tunnel syndrome in recent years. The aim of the present study was to assess the effect of anatomic variations of existence or absence of palmaris longus and fifth superficial flexor tendons on the sonographic measurement of median nerve surface area in healthy individuals’ wris...

The shape of instantaneous water surface profiles for the unsteady flow in tunnel model can be determined by measuring levels at multiple points synchronously. However, measurement accuracy ultrasonic method is affected greatly because complex state when level changes rapidly. Using an optical method, multicamera synchronous difficult to control, and cost high. For single camera measurement, re...

The laccase enzyme is the largest group of Oxidoreductase enzymes and is capable of oxidizing a wide range of organic substrates to water along with molecular oxygen resuscitation. ZnO nanoparticles are known for their specific properties such as chemical stability, high electrochemical coupling rates, and wide range of absorption of radiation as multifunctional compounds. In this study, ZnO po...

The numerical resolution of shallow water equations (SWE) is required in many environmental problems involving free surface flows. upwind augmented Roe’s method [2] widely used due to the robust and stable solutions it offers realistic scenarios if properly corrected deal with entropy fix wet–dry fronts. On other hand, reduced-order models (ROMs) are known achieve more efficiency terms computat...

clogging occurs during mechanical tunneling with a tunnel boring machine (tbm) because of adhesion of clayey soils to the cutterhead and conveyor system. the present study examined the effects of water and sand contents on clogging in montmorillonite clayeysoil. testing was carried out using an adhesion test device on 28 samples with different water and sand contents to determine adhesionstress...

The ribosome is a large complex catalyst responsible for the synthesis of new proteins, an essential function for life. New proteins emerge from the ribosome through an exit tunnel as nascent polypeptide chains. Recent findings indicate that tunnel interactions with the nascent polypeptide chain might be relevant for the regulation of translation. However, the specific ribosomal structural feat...
