in this paper, indium tin oxide (ito) nanoparticles has been prepared by chemical methods under given conditions with solution of indium chloride (incl3·4h2o), tin chloride (sncl4·5h2o) in ammonia solution. the samples were characterized by x-ray diffraction (xrd) and scanning electron microscopy (sem) analyses after heat treatments. the sem results showed that, the size of the ito particles pr...

Year 2021 is special. It sees the renaissance of concept phase and birth a theory for matters much beyond complex numbers single-input single-output (SISO) linear time-invariant (LTI) systems while we celebrate 60th birthday Lei Guo, an exemplary research leader our times. Here give short tutorial newly developed theory, as present.

introduction: evaluating patient with acute scrotum is based on medical history (e.g. age), physical examination, blood tests, urine analysis and imaging studies. differential diagnosis may be difficult. efficacy of serum acute phase proteins in patients with acute scrotum was assessed in this study. materials and methods : 45 patients were recruited and allocated within three sub-groups; acute...

In this paper, we will introduce the notion of conjugate phase retrieval, which is a relaxed definition of phase retrieval allowing recovery of signals up to conjugacy as well as a global phase factor. It is known that frames of real vectors are never phase retrievable on C in the ordinary sense, but we show that they can be conjugate phase retrievable in complex vector spaces. We continue to d...

ticl4, ammonia, inorganic salts as raw material, nanometer composite-crystal tio2 powders were synthesized by two-step chemical method. precursors were crystallized with different phase and stable composite-crystal tio2 with anatase and rutile phase was prepared at low temperature. quantitative control of crystal phase was realized. remarkable factors including reaction ph value, reaction time,...

induction motor especially the squirrel cage type of this motor plays important role in industry. according to the application type, this motor place against various stresses that are caused failure in the motor. the most common failure is related to the stator winding. among these failures are turn-to-turn, coil-to-coil and phase to phase faults. flow the high current do to the induction resul...

introduction: the formalin test is the most accepted chemical test for evaluation of nociception. it requires the injection of an adequate amount of formalin into the surface of the hindpaw. formalin test consists of phase 1 (0-7 min) and phase 2 (15-60) in which the animal shows painful behaviors. these phases are separated with a quiet phase named interphase, in which the nociceptive response...

the present paper seeks to present a minimalist account for the derivational process of marked ergative constructions in hawrami in terms of phase theory (chomsky 2000, 2001, 2004; radford 2009; citko2014). this phase-based approach is compared to the former feature-based approach advocated by karimi doustan and naghshbandi (2011). it is argued that using phase theory and its related mechanisms...
