Transmission synchrotron diffraction was employed to characterize the Ga ordering in magnetostrictive Fe 100−x Ga x alloys with Ga concentrations from 0 to 20.3 at. %. The experiments focused on the development of atomic short-range ordering ͑SRO͒ by analysis of the diffuse scattering appearing at superlattice positions of the D0 3 ordered alloy structure. No SRO was found for Ga concentrations l...

1. A nickel tube magneto-striction oscillator of 320 watts output producing sonic vibrations of 9,300 cycles per second frequency is described. Certain structural innovations contribute to operating efficiency and permit more convenient exposure of test materials than in earlier types. 2. The rate of phage inactivation by sonic waves proceeds logarithmically with time and serves as a satisfacto...

An epitaxial pseudocubic SmFeO3 thin film on (100) Nb-SrTiO3 was studied based on ferroelectric (FE) characterization and magnetic measurements. High-resolution transmission electron microscopy images clarify the nature of the epitaxial growth, the stress-induced structural distortion at the film/substrate interface, and the existence of two different orientation lattices. Clear grain boundarie...

most of the contour detection methods suffers from some drawbacks such as noise, occlusion of objects, shifting, scaling and rotation of objects in image which they suppress the recognition accuracy. to solve the problem, this paper utilizes zernike moment (zm) and pseudo zernike moment (pzm) to extract object contour features in all situations such as rotation, scaling and shifting of object i...

the anti-cancer activity of metal ions in the lanthanide group is being considered recently. it has been reported that cerium salts might stimulate the metabolism and therefore, produce anti-cancer effects. however, little is known about the effects of protein-cerium complex in controlling cancer cell growth. the aim of the present study was to elucidate the possible pathways for the cytotoxic ...

objective: poverty alleviation is an essential step to achieve economic development. this is why identification exercise is so crucial. traditionally, different aspects of insecurities have not be taken into poverty measurement. many types of insecurities have adverse impacts on household welfare. identifying vulnerability of household can serve identification of the poor households. methodolog...

a signed graph (marked graph) is an ordered pair $s=(g,sigma)$$(s=(g,mu))$, where $g=(v,e)$ is a graph called the underlyinggraph of $s$ and $sigma:erightarrow{+,-}$$(mu:vrightarrow{+,-})$ is a function. for a graph $g$, $v(g),e(g)$ and $c(g)$ denote its vertex set, edge set and cut-vertexset, respectively. the lict graph $l_{c}(g)$ of a graph $g=(v,e)$is defined as the graph having vertex set ...

objective: verotoxin is a member of shiga toxin family. this family contains ab protein toxins with an enzymatic (a) and a binding (b) compartment. cells that have receptor (gb3) are sensitive to cytotoxic effects of toxin. it has been shown that various tumor cells have gb3 receptor and are selectively sensitive to apoptotic effect of verotoxin. studies on tumor cell lines and laboratory anima...

in this paper, the optimum shape of tailor-welded blanks (twb) is investigated. the optimization is performed for two different case studies. the first example is deep drawing of a twb with dissimilar materials and uniform thicknesses and the next example is deep drawing of a twb with similar materials and non-uniform thicknesses. the effect of blank optimization on the weld line movement is in...

objective: today, special attention is paid to the use of zirconium dioxide nanoparticle (nano-zro2), a neutral bioceramic metal, particularly for drug and gene delivery in medicine. however, there are some reports implying that use of nano-zro2 is associated with cytotoxic effects like inhibiting the cell proliferation, dna damage and apoptosis. in the present study, we examined whether nano-z...
