six new complexes of the type trans-[lco((do)(doh)pn)l'] where (do)(doh)pn= n2, n2'-propanediolbis (2,3-butanedione 2-imine 3-oxime), l-cl¯ and l'=mono-anaion of phenylcyanamide (pcyd), 2,5-dichlorophenylcyanamide (2,5-cl2 pcyd), 2,4-dimethyl pehylcyanamide (2,4-me2 pcyd) and l=l'=pcyd, 2,5-cl2 pcyd, 2,4-me2 pcyd, have been synthesized and characterized by elemental analysis, spectroscopy and c...
we introduce the notion ofstrongly $alpha$-reversible rings which is a strong version of$alpha$-reversible rings, and investigate its properties. we firstgive an example to show that strongly reversible rings need not bestrongly $alpha$-reversible. we next argue about the strong$alpha$-reversibility of some kinds of extensions. a number ofproperties of this version are established. it is shown ...
in this paper, we introduce a class of rings which is a generalization of reversible rings. let r be a ring with identity. a ring r is called central reversible if for any a,b ∈ r, ab=0 implies ba belongs to the center of r. since every reversible ring is central reversible, we study sufficient conditions for central reversible rings to be reversible. we prove that some results of reversible ri...
This study presents the importance of reversible logic in designing of high performance and low power consumption digital circuits. In our research, the various forms of sequential reversible circuits such as D, T, SR and JK flip-flops are investigated based on carbon nanotube field-effect transistors. All reversible flip-flops are simulated in two voltages, 0.3 and 0.5 Volt. Our results show t...
Electrochemical behavior of I-hydroxypyridine-2-thione and its vanadium complex is studied using polarographic techniques. Polarograms of ligand and that of the complex is shown with diffusion characteristics of the waves. Cyclic voltagram of thione is investigated which shows that a reversible oxidation reduction of one electron process is taking place. PKa of the thione is found to be in ...
