Fracture load of ceramic restorations after fatigue loading

The Journal of Prosthetic Dentistry, 2015
A clinician must decide what ceramic coping and veneer material to prescribe based on the amount of tooth reduction possible and the desired esthetic outcome of the restoration.The purpose of this in vitro study was to compare the fracture strength of monolithic and bilayered lithium disilicate (IPS e.max) and zirconia (LAVA) crowns at clinically ...

Maximum restorable load for substation during power system restoration

2009 International Conference on Sustainable Power Generation and Supply, 2009
In power system reconfiguration after successful black start, the maximum restorable load that substation can pick up at one time should be given. Presently, researches about the problem usually concentrate on frequency constraint and steady-state voltage constraint.

Effective Method for Load Restoration

SSRN Electronic Journal, 2013
In our country power demand is a major problem so we are going to introduce an algorithm based on genetic algorithm is proposed to solve service restoration problem in power distribution systems with priority customers. In genetic algorithm new solutions are found in every next generation with probability of getting the better solution till the optimal

Adaptive underfrequency load shedding and underfrequency load restoration system

2005 IEEE Russia Power Tech, 2005
Paper deals with the problem of power system control during emergency situation, caused by generating power deficiency. Deep frequency decline usually is prevented with the help of frequency-actuated load shedding automation. Analysis of existing load shedding system showed possibility of power system blackout due to improper parameters of emergency ...

Recovery periods restore mechanosensitivity to dynamically loaded bone

Journal of Experimental Biology, 2001
SUMMARYBone cells are capable of sensing and responding to mechanical forces, but mechanosensitivity begins to decline soon after the stimulus is initiated. Under continued stimulation, bone is desensitized to mechanical stimuli. We sought to determine the amount of time required to restore mechanosensitivity to desensitized bone cells in vivo by ...

Dentinal Fluid Movement Associated with Loading of Restorations

Journal of Dental Research, 1991
Post-operative biting sensitivity is a significant clinical problem after placement of posterior resin composites and may be due to dentinal fluid movement. The occlusal surfaces of extracted teeth were filled with amalgam (control) or various posterior resin composites, and the movement of the dentinal fluid induced by the loading of the restorations

LOAD TRANSFER RESTORATION AT JOINTS

Proceedings of the International Conference on Concrete Pavements
The development of a cost-effective method for restoring load transfer at concrete pavement joints has significant implications for maintaining the longevity and usability of roadways. Recognizing early signs of damage in concrete pavements, a French team proposed an innovative solution to restore load transfer by using a method that involves minimal ...
