Non-hereditary Minimum Deep Coalescence trees
— One of the goals of phylogenetic research is to find the species tree describing the evolutionary history of a set of species. But the trees derived from geneti data with the help of tree inference methods are gene trees that need not coincide with the species tree. This can for example happen when so-called deep coalescence events take place. It is also known that species trees can differ fr...
متن کاملControlled electro-coalescence/non-coalescence on lubricating fluid infused slippery surfaces
Aqueous drops on silicone oil infused lubricating surfaces are cloaked with a thin layer of oil to minimize their surface energy. These oil cloaked aqueous drops exhibit pseudo-stable coalescence or spontaneous coalescence depending upon the lubricating oil thickness which controls the interaction point of the drops. For thick oil films, drops interact with each other through the surrounding oi...
متن کاملDesigning and Manufacturing the Multiple Jets Simulator and Experimental Investigation of the Multiple Jets in Crossflow
Designing and manufacturing the multiple jets simulator and experimental investigation of the multiple jets in crossflow at low velocity ratios have been studied Together with design and build a low-speed wind tunnel. A specific rake is used to determine the flow field pressure and changes in static pressure measured by pressure taps in the near field of the jets. There are generally three regi...
متن کاملNon-coalescence of oppositely charged droplets in pH-sensitive emulsions.
Like charges stabilize emulsions, whereas opposite charges break emulsions. This is the fundamental principle for many industrial and practical processes. Using micrometer-sized pH-sensitive polymeric hydrogel particles as emulsion stabilizers, we prepare emulsions that consist of oppositely charged droplets, which do not coalesce. We observe noncoalescence of oppositely charged droplets in bul...
متن کاملExperimental Study of Parallel Jets Scouring, considering the effect of jets distance on erosion rate
The scouring process at downstream of the hydraulic structures is a complex phenomenon and many parameters affecting its amount. Failure to control this phenomenon causes damages to the dam and its associated hydraulic structures. In this research, the scouring caused by the combination of jets outlet from a gated spillway was investigated experimentally and the combination of jets adjacent to ...
