The aim of this study was to compare the cyclic fatigue resistance (CFR) PathFile (Dentsply Sirona, Ballaigues, Switzerland) and ScoutRace (FKG Dentaire, La Chaux-de-Fonds, glide path files which were either new or previously used. Forty (PF) 19/.02 40 (SR) 20/.02 instruments used for study. Half in each group (PF-U SR-U) 3D demo tooth models creating paths, while other half (PF-N SR-N) directl...

this paper presents the results of a series of monotonic and post-cyclic triaxial tests carried out on a clay specimen and three types of clay-sand mixed specimens. the focus of the paper is on the post-cyclic mechanical behavior of the mixed specimens, as compared to their monotonic behavior. analyses of the tests results show that cyclic loading degrade undrained shear strength and deformatio...

in this paper, the effect of cationic and anionic ion sizes on the charge storage capability of graphene nanosheets is investigated. the electrochemical properties of the produced electrode are studied using cyclic voltammetry (cv) and electrochemical impedance spectroscopy (eis) techniques in 3m nacl, naoh, and koh electrolytes. scanning electron microscopy (sem) is used to characterize the mi...

In this paper, we present the performance of a parallel interference cancellation (PIC) scheme in Code division multiple access with cyclic prefix (CP-CDMA) systems and proposed a new model for cyclic prefix code division multiple access with less complexity and good resistance to near-far effect. This method is mostly used for broadband wireless communication in the uplink. Parallel interferen...

The potency of the nitric oxide (NO) donors glyceryltrinitrate (GTN) and 3-morpholinosydnonimine was compared in human dorsal hand veins, the radial artery, and the forearm resistance vessels. NO donors were more potent in veins and the radial artery (vessels with minimal basal NO-mediated dilatation) than in the resistance vascular bed (where basal NO is a major determinant of vascular tone). ...
