Separating clods from potato tubers is one of the most challenging jobs in a potato harvester. Discriminating between potato tubers and clods is the first step in developing an automatic separation system on potato harvesters. In this study, an acoustic-based intelligent system was developed for high speed discriminating between potato tubers and clods. About 500 kg mixture of potato tubers and...

To research the effect of temperature on interfacial bonding strength steel cord rubber conveyor belt, an electronic universal material testing machine and a control box were used as test equipment. The withdrawal force skeleton belt was tested in range −30 °C to +40 °C. Concurrently, morphology between at different temperatures observed by using ultra deep field electron microscope. Finally, p...

Steel production is the most dynamic industry and one of key sectors for development global economy. The growing iron ore increases need its beneficiation granulating subsequent use in steel. As a result, number CO2 emissions harmful substances increases, which negatively affects both society environment. It important to study biomass pellets. Lignocellulosic renewable sustainable source heat e...

OBJECTIVES To evaluate modifications in root canal morphology following instrumentation with orifice openers using Computerized Tomography (CT). STUDY DESIGN Experimental in vitro study. A preoperative CT was performed on 49 molars to measure the root canal cross-sections. After preparing the canals with 6 different nickel-titanium (Ni-Ti) rotary system orifice opener type instruments and Gat...

The study compared changes to canal curvature and incidence of canal aberrations after preflaring with hand K-files or with nickel-titanium rotary PathFile in S-shape Endo Training Blocks. The influence of the operator's expertise was also investigated. One hundred training blocks were colored with ink, and preinstrumentation images were acquired digitally. Preflaring was performed by an endodo...

OBJECTIVE To compare the disinfecting efficacy of the sodium hypochlorite irrigation by root canal preparation with stainless steel hand files, taper 0.02 and nickel-titanium Mtwo files with taper 0.04-0.06. STUDY DESIGN 40 extracted human teeth were sterilized, and then inoculated with Enterococcus faecalis (ATCC 29212). After 6 day incubation time the root canals were prepared by hand with ...
