On the bipartite case of El-Zahárs conjecture

A special case of a conjecture of M. El-Zahár states that a graph G with 2k vertices and minimum degree k, contains every bipartite 2-regular graph H on 2k vertices as a spanning subgraph. In this paper it will be proved that G contains the union of (k− 1) cycles of lengths 4 and a path of order 4. Using this result it will also be proved that G contains the union of (k−2) cycles of lengths 4 a...

Analysis of Multiple Yoffe-type Moving Cracks in an Orthotropic Half-Plane under Mixed Mode Loading Condition

The present paper deals with the mixed mode fracture analysis of a weakened orthotropic half-plane with multiple cracks propagation. The orthotropic half-plane contains Volterra type glide and climb edge dislocations. It is assumed that the medium is under in-plane loading conditions. The distributed dislocation technique is used to obtain integral equations for the dynamic problem of multiple ...

Causality relationships between coagulation factors in type 2 diabetes mellitus: path analysis approach

 Background: Type 2 diabetic mellitus patients are amongst the most susceptible groups to vascular abnormalities, which predominantly lead to myocardial disease. The hypercoagulable state has been widely studied by researchers as being the major suspicious mechanism facilitating the consecutive chain of molecular events leading to these complications. However, there is no consensus on the defin...
