electrochemical behavior of the new mono and dinuclear co (iii)  complexes of  the types trans-[pyco((do)(doh)pn )(l)]pf6   and [{py co((do)(doh)pn)}2 (μ-dicyd)] (pf6)2   have been studied in acetonitrile solution.  all the  mono nuclear complexes  show two quasi- reversible reduction couples associate  to co(iii/ii)and  co(ii/i). each of these redox couples split to two  one electron  waves in...

In this research, Cu-phthalocyanine coated hybrid magnetic nanoparticles have been prepared in a simple method and evaluated as an efficient catalyst in the preparation of mono- and bis-pyrano[2,3-d]pyrimidinones and mono- and bis-2-amino-4H-pyrans from the condensation reaction of 1,3-dimethylbarbituric acid or 4-hydroxycumarin with malononitrile and mono- and bis-aldehydes under ultrasoni...

In Multipregnancies, The careful control of Number of follicles in stimulation cycles and Number of embryos transferred in ART cycles is so important. Just twin pregnancies are reason for racial death (12- 15%). The risk for CP in twin pregnancies is 8 times more and for Triple is 47 times more than simple ones.Approximately all prenatal problems increase in multiple pregnancies and therefore t...

TGF-beta activates receptor-regulated Smad (R-Smad) through phosphorylation by type I receptors. Activated R-Smad binds to Smad4 and the complex translocates into the nucleus and stimulates the transcription of target genes through association with co-activators including p300. It is not clear, however, how activated Smad complexes are removed from target genes. In this study, we show that TGF-...

The concepts of intrinsic mode functions and mono-components are investigated in relation to the empirical mode decomposition. Mono-components are defined to be the functions for which non-negative analytic instantaneous frequency is well defined. We show that a great variety of functions are mono-components based on which adaptive decomposition of signals are theoretically possible. We justify...

In order to better understand the chiral recognition mechanisms of positively charged cyclodextrin (CD) derivatives, synthesis, pKa determination by 1H nuclear magnetic resonance (NMR)-pH titration and a comparative capillary electrophoretic (CE) study were performed with two series mono-substituted cationic single isomer CDs. The first selectors mono-(6-N-pyrrolidine-6-deoxy)-β-CD (PYR-β-CD), ...

Abstract Creating suitable classrooms that can meet the educational needs of mentally-retarded students is vitally important. The present study explores the effect of three physical characteristics of classroom environment on the creativity of educable mentally-retarded children: window view, window size, and classroom size. The participants, one hundred 9-to-11-year-old girl students, took th...

Introduction: Scatter radiation is one of the major sources of error in nuclear medicine data processing. Different methods of scatter correction have been introduced in order to improve the quality of data. However the best method is to avoid recording of scatter photons in acquisition. The only difference between scattered and non-scattered photons is the energy. Pulse height analyzer i...

The present study analyzes the seasonal variability of relationship between land surface temperature (LST) and normalized difference bareness index (NDBaI) on different use/land cover (LULC) in Raipur City, India by using sixty-five Landsat images four seasons (pre-monsoon, monsoon, post-monsoon, winter) 1991-1992, 1995-1996, 1999-2000, 2004-2005, 2009-2010, 2014-2015, 2018-2019. mono-window al...

The effects of mono- and dibutyl phthalate and mono- and di(2-ethylhexyl) phthalate on energy-dependent K+ uptake, respiration rates, and succinate cytochrome c reductase activities of isolated rat liver mitochondria were evaluated. The energy-coupling processes, active K+ transport and oxidative phosphorylation, were affected most by di-n-butyl phthalate and mono(2-ethylhexyl) phthalate. Mono-...
