let $r$ be a commutative ring with identity. let $g(r)$ denote the maximal graph associated to $r$, i.e., $g(r)$ is a graph with vertices as the elements of $r$, where two distinct vertices $a$ and $b$ are adjacent if and only if there is a maximal ideal of $r$ containing both. let $gamma(r)$ denote the restriction of $g(r)$ to non-unit elements of $r$. in this paper we study the various graphi...
Paroxysmal Permanent Junctional Reciprocating Tachycardia (PJRT) is caused after rapid and sudden pacing of excitatory foci in atrioventricular junction . While it happens mostly in infants and children, it is rarely seen in adults. A 30-year-old female came to our emergency department repeatedly with the chief complaint of palpitation. She was later diagnosed with PSVT and throughout her s...
the purpose of this study was to investigate the relationship between teachers’ class management practices with students’ self- regulated learning and academic self-efficacy. in this study relating to the management class, three dimensions, (training management, people management and behavior management) and three style (interventionist, interactionist and non-interventionist) was considered. r...
Background: This study aimed to evaluate the dose calculation accuracy of EclipseTM treatment planning system (TPS) in a heterogeneous chest phantom with the intensity modulated radiotherapy (IMRT) technique using EBT3 film and Delta4. Materials and Methods: Two IMRT plans (A and B) were prepared for radiotherapy of the heterogeneous chest phantom. Plan A was between the left lung and the surro...
the purpose of this study was to examine the status of supervision on departments’ heads at ferdowsi university of mashhad (fum) and realize some applied themes to provide a fit model for supervising departments’ heads in fum. the method was case study under a research category aimed for applied one. using purposive sampling, interviews were conducted with top fum managers, head departments, an...
chapter two presents three m-admissible function algebras ab, bd, and sl, to construct the universal abelian, band, and semilattice compactifications, respectively. the main results are (11.3), (12.3), and (12.4). some inclusion relationships between these function algebras and the other well-known ones, presented in section 8, are made via the devico of compactifications. chpter three is about...
Let $G$ be a group. The order graph of $G$ is the (undirected)graph $Gamma(G)$,those whose vertices are non-trivial subgroups of $G$ and two distinctvertices $H$ and $K$ are adjacent if and only if either$o(H)|o(K)$ or $o(K)|o(H)$. In this paper, we investigate theinterplay between the group-theoretic properties of $G$ and thegraph-theoretic properties of $Gamma(G)$. For a finite group$G$, we s...
فرض کنید $ r $ حلقه ای جابه جایی و یکدار و $ z(r) $ مجموعه مقسوم علیه های صفر حلقه $ r $ باشد. گراف جمعی حلقه $ r $ گرافی است که رئوس آن عناصر حلقه می باشد و دو راس متمایز $ x $ و $ y $ مجاورند اگر و تنها اگر $ x+y in z(r) $ . این گراف با نماد $ t(gamma(r)) $ نمایش داده می شود. در این پایان نامه دو زیر گراف $ t_0(gamma(r)) $ و $ z_0(gamma(r)) $ که رئوس آن به ترتیب $ r ^* $...
