vascular lesions rise from abnormalities in blood vessels or endothelial proliferation . capillary hemangiomas are formed by small capillaries surrounded by a layer of endothelial cells in a connective tissue stroma . various treatments are used for these conditions like excisional surgery , sclerotherapy, and recently laser irradiation. in this case study, we report successful treatment of int...

Liquid in grooved capillaries, made by e-ginserting a plate in a cylindrical tube, exhibits unusual spreading and flow properties. One example is capillary rise, where a long, upward tongue on top of the usual meniscus has been observed along the groove. We attribute the underlying mechanism to a thermodynamic instability against spreading for a (partial
