o bjectives: providing reliable attachment between bracket base and zirconia surface is a prerequisite for exertion of orthodontic force. the purpose of the present study was to eval- uate the effect of four zirconium surface treatment methods on shear bond strength (sbs) of orthodontic brackets. mat erials and methods: one block of zirconium was trimmed into four zirconium sur- faces, which se...

Introduction: Photothermal therapy using gold nanoshells is one of cancer therapy methods. Gold nanoshells generally consist of a silica core and a thin gold shell. Fe3O4@Au core-shell can be used for magnetic targeted therapy. The objective of this study was investigation of the photothermal effects of magnetically targeted Fe3O4@Au NPs and NIR laser irradiation on model of me...

OBJECTIVE The purpose of this study was to measure specific absorption rate (SAR) during MRI scanning using a human torso phantom through quantification of diffusion coefficients independently of those reported by the scanner software for five 1.5 and 3 T clinical MRI systems from different vendors. METHODS A quadrature body coil transmitted the RF power and a body array coil received the sig...

In this study, Microwave-Assisted Solvent Extraction (MASE) was used to recover oil residues from pomace olive using acidic hexane. Results obtained demonstrated that oil extraction yield increased with time, the amount of acetic acid in hexane and power radiation. For both radiation powers used (170 and 510W), the optimal extraction time and most interesting content of acetic acid in hexan...

The realization of biomass-derived supercapacitors high performance is practical importance for the manufacturing from green and renewable sources. Herein, feasibility constructing high-performance potato-derived activated carbon (AC) demonstrated. AC produced potato mash through hydrothermal treatment high-temperature activation with KOH as agent. aqueous electrolyte 6 m a mass loading 5 mg pe...

objective: the main objective pursued in this paper is to investigate the energy consumption for drying of potato slices using vacuum-infrared drying method. methods: drying of potato slices with the thicknesses of 1, 2 and 3 mm were conducted at vacuum levels of zero (without vacuum), 20, 80 and 140 mm [hg], infrared radiation at power levels of 100, 150 and 200 w in the three repetition. resu...

The effects of changes in nominal bargaining power, the proposal selection rule and discounting in legislative bargaining outcomes are investigated. The comparative static predictions of the Baron-Ferejohn (1989) model better organize behavior than does Gamson’s Law (1961). However, proposer power is not nearly as strong as predicted under Baron-Ferejohn as coalition partners refuse to take the...

In this paper, a new control strategy is proposed for implementation in low-voltage microgrids with balanced/ unbalanced load circumstances. The proposed scheme contains, the power droop controllers, inner voltage and current loops, the virtual impedance loop, the voltage imbalance compensation. The proposed strategy balances the voltage of the single-phase critical loads by compensating the im...
