background calcium infusion is used as a pre-treatment before calcium channel blockers to prevent hypotension. occasional cardioversion with calcium gluconate infusion is seen in patients with paroxysmal supraventricular tachycardia. several mechanisms have been suggested for mechanism. herein we report a case presenting with atrial fibrillation but cardioverted with calcium gluconate infusion,...

This paper highlights network survivable schemes in order to guarantee both protection and restoration in high speed networks. In this paper, a hybrid protection and restoration mechanism has been proposed whose objective is allocating the bandwidth in a way that minimizes the total amount of bandwidth used for working and protection paths. In the proposed mechanism, path-based protection has b...

Submarine landslides are a major marine geohazard affecting resilience of offshore infrastructure and coastal urban centers. Attention has previously been paid to quantifying post-failure dynamics catastrophic submarine debris flows their consequences. However, pre-failure initiation growth small slip surface evolving into large landslide still less understood. This study aims explore the physi...

Understanding the tensile strength properties and damage evolution mechanism in fissured rock is very important to fundamental research engineering design. The effects of flaw dip angle on strength, macroscopic crack propagation failure mode symmetrical Brazilian discs rock-like materials were investigated. A parallel bonding model was proposed examine pre-flawed under splitting load. microscop...

The success of pre-operative therapy over post-operative treatments means that a technique identifying prognostic factors pre-operatively is of potential benefit in modifying the intensity of pre-operative therapy according to risk of local or distant failure. Clinical trials incorporating robust and accurate assessment of prognostic factors and appropriate stratification of patients prior to t...

ln this paper, we propose a fast restoration mechanism for virtual path-based ATM networks. Given an ATM network topology, the capacity of each physical link, and the primary virtual path (VP) layout at system initialization, the proposed mechanism pre-assigns to each primary VP one backup VP such that (PI) the failure of a single node/link does not lead to the failure of both the primary and b...

The aim of this study was to evaluate the fracture load and failure mode of all-ceramic crowns with different ceria-stabilized tetragonal zirconia/alumina nanocomposite (Ce-TZP/A) framework designs. Four frameworks (anatomical shape: AS, with a buccal or lingual supporting structure: BS and LS, or buccal and lingual supporting structures: BLS) were fabricated. All frameworks were veneered with ...

The main aim of this research was to find the mechanism for the failure of the CoCrMo porous nano-composite by characterizing microstructural changes and fractured surface after compression test. For this purpose, porous nano-composites were prepared with the addition of bioactive glass nano-powder to Co-base alloy with 22.5% porosity by the combination of space-holder and powder metallurgy tec...
