BACKGROUND: The purpose of this study was to evaluate the sensitometric characteristics of Ultraspeed, Ektaspeed Plus and Insight dental radiographic films using manual and automatic processing systems. METHODS: In this experimental invitro study, an aluminum step-wedge was used to construct characteristic curves for D-, E- and F-speed radiographic films (Kodak Eastman, Rochester, USA). All fil...
This paper considers identical parallel machines scheduling problem with past-sequence-dependent setup times, deteriorating jobs and learning effects, in which the actual processing time of a job on each machine is given as a function of the processing times of the jobs already processed and its scheduled position on the corresponding machine. In addition, the setup time of a job on each machin...
Plasma electrolysis is a novel method for synthesis and processing of materials and nanomaterials, which uses plasma-solution interaction. In this paper, a simple setup of pin-to-solution electrical discharge with aqueous solution of silver nitrate in normal air is used. Experimental observations show that by start of electrical discharge and formation of air plasma between metal pin and soluti...
