Effect of Crest Roughness on Flow Characteristics over Circular Weirs
Different construction materials with different roughness used to make circular weirs highly affect surface roughness and, in turn, flow hydraulics passing over these structures. In the present research, numerous experiments under different hydraulic conditions were performed on a physical model to study the effects of roughness on flow hydraulics over a circular weir. The flow hydraulics incl...

Neural Crest
Early in the process of development, vertebrate embryos develop a fold on the neural plate [6] where the neural and epidermal ectoderms meet, called the neural crest [7]. The neural crest [7] produces neural crest cells [8] (NCCs), which become multiple different cell types and contribute to tissues and organs as an embryo develops. A few of the organs and tissues include peripheral and enteric...
