Thevenin Equivalents of Some Interesting Networks with Dependent Sources [PDF]

open access: yesIETE Journal of Education, 2014
ABSTRACTThis paper presents two classes of networks whose Thevenin equivalents are interesting. One class of networks is without any independent source. The other class has loop or node method-based delta 0. If proper care is not taken, then their Thevenin equivalent resistances may result in indeterminate forms.

Caenogastropods and heterobranch gastropods from the Hettangian deposits of Luxembourg: palaeobiogeography and Early Jurassic faunal recovery in the western Tethys

open access: yesPapers in Palaeontology, Volume 12, Issue 1, January/February 2026.
Abstract We describe the Hettangian Caenogastropoda and Heterobranchia of the Luxembourg Sandstone Formation, a wedge of clastic sediments deposited along the eastern margin of Paris Basin during the Early Jurassic. Five new genera and 11 new species are erected: Bourguetia bipartita sp. nov., Globularia delsatei sp. nov., Oonia feidtorum sp.
