lonophore-based ion-selective optical nanosensors have been explored for a number of years. Voltage sensitive dyes (VSDs) have been introduced into this type of sensors only very recently, forming a new class of analytical tools. Here, K(+)-sensitive nanospheres incorporating a lipophilic VSD were successfully fabricated and characterized. The nanosensors were readily delivered into the social ...

An enhanced unfolding Inverse Finite Element Method (IFEM) has been used together with an extended strain-based forming limit diagram (EFLD) to develop a fast and reliable approach to predict the feasibility of the deep drawing process of a part and determining where the failure or defects can occur. In the developed unfolding IFEM, the meshed part is properly fold out on the flat sheet and tre...

the forming limit diagram (fld) is a useful method for characterizing the formability of sheet metals. in this paper, different numerical models were used to investigate the fld of tailor welded blank (twb). twbs were co2 laser-welded samples of interstitial-free (if) steel sheets with different thicknesses. the results of the numerical models were compared with the experimental fld as well as ...

objectives: the aim of this study was to evaluate the effect of gutta percha/ah26 and resilon/realseal se on residual antimicrobial activity of chlorhexidine (chx) in human root dentin and suggest the best filling material when chx is used as final irrigant. materials and methods: one-hundred and forty-four single-rooted human teeth were selected for this study. canals were instrumented to the ...

In this paper, the design and implementation of plasma antenna array with beam forming is discussed. The structure consists of a circular array of plasma tube enclosed in a unipolar UHF band monopole antenna. Beam forming is possible by stimulated plasma tubes. The combination of the above antenna with plasma excitation controller makes a beam forming smart antenna. An experimental model in UHF...

because of high strength to weight ratio, 6061 aluminum has many applications in different industries like automotive and aerospace industries and can help to reduction of fuel consumption. forming limit diagram (fld) is a useful method for sheet metal formability identification. whereas calculation of forming limit diagram by experimental tests is expensive and time consumption, in the present...

introduction: this study evaluated and compared colony forming units (cfus) and minimum inhibitory concentrations (mics) of calcium hydroxide and propolis as intracanal medicaments. materials and methods: eighty human single-root and caries-free teeth were selected and divided into five groups. crowns were removed. root canals were then prepared in a step-back manner. the samples were then inoc...

there are many parameters that affect the sheet hydroforming process such as fluid pressure, material properties, interfacial friction between blank and tool surfaces, etc. in this paper, a fem-based taguchi method is used to determine the effects of forming parameters on the quality of part formability in the process of hydrodynamic deep drawing assisted by radial pressure. four important form...
