In 1962, S. L. Hakimi proved necessary and sufficient conditions for a given sequence of positive integers d1, d2, . . . , dn to be the degree sequence of a non–separable graph or that of a connected graph. Our goal in this note is to utilize these results to prove closed formulas for the functions dns(2m) and dc(2m), the number of degree sequences with degree sum 2m representable by non–separa...

This paper introduces a new approach to topology, based on category theory and universal algebra, and called categorically-algebraic (catalg) topology. It incorporates the most important settings of lattice-valued topology, including poslat topology of S.~E.~Rodabaugh, $(L,M)$-fuzzy topology of T.~Kubiak and A.~v{S}ostak, and $M$-fuzzy topology on $L$-fuzzy sets of C.~Guido. Moreover, its respe...

background: infant's transition is a challenge for parents and the health system that requires ongoing assessment and management to improve each newborn`s growth and development. the purpose of this study was to explore the management of infant` transition from neonatal intensive care unit (nicu) to home.materials and methods: we used a grounded theory study to explore and describe the man...

In this research, the effects of Al&S doped on the HCN interaction with beryllium oxide nanotube (BeONTs) are investigated by using density functional theory at the cam-B3LYP/6-31G (d) level of theory. Inspection of computational results reveals that the adsorption energies of all considered models are in range of −1.39 to −31.84 Kcal/mol and exothermic in view of thermodynamic approach. Due to...

the menhaj al-bolagha and seraj al-odaba by hazem qartajeni is one of the most effective books on rhetoric and theory of arabic poetry. although he was grown up in an environment influenced by ibn rushd and is considered his indirect student, in this book (with a rhetoric and philosophical style) he is under the influence of ibn sina in founding and presenting the theory of arabic poetry. witho...

abu `al-barakat al-baghdadi, before explanation of his selected view about the problem of the quality of emergence of multitudinous from unit, expresses the theory of peripatetic philosophers with a historical outlook. he then critics the viewpoint of peripatetic philosophers and finally explains his view in the course of four descriptions. the following points are proposed when criticized his ...

it seems using the maxwell-stefan (m-s) diffusion model in combination with the vacancy solutiontheory (vst) and the single-component adsorption data provides a superior, qualitative, andquantitative prediction of diffusion in zeolites. in the m-s formulation, thermodynamic factor (г) isan essential parameter which must be estimated by an adsorption isotherm. researchers usually utilizethe simp...

A Critical Review of Kohlberg’s Theory of Moral Judgment and a Guideline on its Developmental Stages   A.R. Assaareh, Ph.D. * A. Mahdizaadeh Tehraani** A.R. Amini Zarrin*** S. Azimi****   Developmental theories describe and explain stages in which different aspects of human psyche develop. Among such theories is Kohlberg’s theory of moral judgment wherein a complex ...
