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...

An efficient, simple and convenient route is described for the synthesis of biscoumarin (3,3'-(arylmethylene) bis (4-hydroxy-2H-chromen-2-one)) by using of recyclable catalyst TiO2@KSF. In this Method, we synthesis biscoumarin derivatives via 3multi-component reactions (3MCRs) of two equivalent 4-hydroxycoumarin with one equivalent of aromatic aldehydes using 20 mg nano TiO2@KSF as homogeneous ...

Recently, a flash memory has become a major database storage in building portable information devices because of its non-volatile, shock-resistant, power-economic nature, and fast access time for read operations. We propose a new scheme called flash memory shadow paging (FMSP) scheme for efficient page management in a flash memory database environment. We improved traditional shadow paging sche...

In this paper, we proposed a 2-D analytical model for electrical characteristics such as surface potential, electric field and drain current of Silicon-on-Insulator Tunnel Field Effect Transistor (SOI TFETs) with a SiO2/High-k stacked gate-oxide structure. By using superposition principle with suitable boundary conditions, the Poisson’s equation has been solved to model the channel r...

We constructed, stored on disk and reused suux trees and suux binary search trees for C. elegans chromosomes, and measured their performance using orthogonal persistence for Java (PJama). We compare our implementation with the performance of a transient 1 suux tree, and discuss the suitability of such indexes in pursuing our long-term goal of indexing large genomes. We identify the potential fo...
