Colour Doppler evaluation of varicose veins
International Journal of Research in Medical Sciences, 2016 Background: Varicose veins are irreversibly dilated epifascial and perforating veins resulting from degenerative vascular wall changes, Depending on the aetiology, they are classified into Primary & Secondary forms. In the present clinical prospective studies, we evaluated the impact of ultrasound examinations on the pre-operative diagnosis of ...

Deep Underground Science and Engineering, EarlyView.Fluid flow through a single fracture is commonly described by the cubic law. However, deviations from this model are expected because natural fracture surfaces are rough and in contact with each other in discrete regions. In this study, the interactions between fracture closure, contact area, and hydraulic characterization of mesoscopic‐scale rough ...
