Abstract: 

P. HALL INTRODUCED THE NOTION OF ISOCLINISM IN ORDER TO CLASSIFY GROUPS OF PRIME POWER ORDER. THE NOTION OF ISOCLINISM CAN BE SIMULATED FOR PAIRS(G; N) OF GROUPS, IN WHICH G IS A GROUP AND N IS A NORMAL SUBGROUP. THIS TALK VERIFIES THE CLASSIFICATION OF SOME PAIRS OF GROUPS, WHENN IS TO BE CHOSEN A SUITABLE SUBGROUP. THEN USING THIS, WE EXPLAIN HOW THIS CLASSIFICATION CAN BE CONSIDERED AS THE FIRST STEP OF SCREENING FOR CLASSIFICATION OF SOME CLASSES OF GROUPS.

IN 1940, P. HALL DEFINED AN EQUIVALENCE RELATION, CALLED ISOCLINISM, AND APPLIED IT FOR CLASSIFYING ALLP -GROUPS OF ORDER AT MOST P5 (P>3) INTO TEN FAMILIES (FORMULA) THIS PAPER INTENDS TO CHARACTERIZE ALL THE FAMILIES WHICH HAVE THE NILPOTENT PRODUCTS OF CYCLIC GROUPS IN THEMSELVES, AND THEN DETERMINE THE EXACT STRUCTURES OF THESE PRODUCTS.

Abstract: 

Introduction: According to International CLASSIFICATION of Functioning, Disability and Health (ICF), children with Cerebral palsy may have considerable impairments and limitations in all levels of body structure and functioning, activity, and participation in social roles. The purpose of this study was to evaluate the efficacy of adapted constraint induced movement therapy (CIMT) on outcome measurements based on ICF levels.Materials and Methods: In a single-blinded randomized controlled trial, 28 participants who met preset inclusion and exclusion criteria were divided into two GROUPS: CIMT and the controls. Subjects in CIMT group were provided with the intervention for 10 out of 12 consecutive days and another group received routine occupational therapy services. Independent-sample t test and paired-sample t test were used for statistical analysis of data.Results: At ICF level of body structure and function, significant differences in shoulder muscle tone and forearm and wrist passive range of motion (PROM) were found between the two studied GROUPS. At activity and participation levels, similar differences were also indicated in dexterity, bilateral coordination, bimanual coordination and Caregiver Functional Use Survey (how well & how frequently) (P<0.05).Conclusion: Implementing the adapted constraint induced movement therapy protocol through a child friendly approach was proved to improve hand functions and activities of daily living.

Abstract: 

Given a finite group G and a subset S  G; the bi-Cayley graph BCay(G; S) is the graph whose vertex set is G  f0; 1g and edge set is ff(x; 0); (sx; 1)g: x 2 G; s 2 Sg. A bi-Cayley graph BCay(G; S) is called a BCI-graph if for any bi-Cayley graph BCay(G; T); BCay(G; S)  =B C a y ( G; T ) implies that T = gS for some g 2 G and 2 Aut(G). A group G is called an m-BCI-group if all bi-Cayley graphs of G of valency at most m are BCI-graphs. It was proved by Jin and Liu that, if G is a 3-BCI-group, then its Sylow 2-subgroup is cyclic, or elementary abelian, or Q8 [European J. Combin. 31 (2010) 1257{1264], and that a Sylow p-subgroup, p is an odd prime, is homocyclic [Util. Math. 86 (2011) 313{320]. In this paper we show that the converse also holds in the case when G is nilpotent, and hence complete the CLASSIFICATION of nilpotent 3-BCI-GROUPS.

Abstract: 

AbstractContext and purpose. The purpose of this research is to design a model for the development of cultural and creative industries through economic tools and mechanisms and the integration of creative and cultural economy.Methodology/approach. In the current study, the qualitative method of grounded theory was used and the in-depth interview technique was used to collect information. The sampling method of the research was purposeful and snowball methods with theoretical saturation criteria and interviews with 20 experts in the field of creative and cultural industries. open, axial and selective coding processes was used to data analysis, and after that, the grounded theory emerging from the data was presented in the form of a story and visual model, and based on them, definition and CLASSIFICATION were carried out for the application of the development of creative and cultural industries. Findings and conclusions. The results have shown that training and empowerment of cultural and creative industries and culture building in the field of cultural and creative industries act as intervening conditions to encourage business owners to create cultural and creative jobs, and these three-dimensional conditions in interaction together have caused the development of cultural and creative industries and the dynamics of the economy and moving towards the creative economy, and the consequence of that is the creative ecosystem approach to economic benefits and economic profitability and cultural development.Originality/innovation. Previous researches have pointed out factors affecting cultural industries or creative industries separately and from different perspectives,

Abstract: 

The equivalence relation isoclinism partitions the class of all pairs of GROUPS into families. In this paper, a complete CLASSIFICATION of the set of all pairs (G, G’) is established whenever, p is a prime number greater than 3 and G is a p-group of order at most p5. Moreover, the CLASSIFICATION of pairs (H, H’) for extra special p-GROUPS H is also given.

Abstract: 

Let G be a finite group and Z(G) be a subgroup of it. Suppose that for the finite group G, Pi_e(G) denotes the set of orders of elements of G. Then G is an EPPO-group if the orders of its elements are non-negative powers of primes. Also, for a subset A of G, let r_G(A) be the number of conjugacy classes of G that intersect A non-trivially. The purpose of this paper is to classify all finite EPPO-GROUPS with the property r_G(G-Z(G))=7. We first verify the case where Z(G)=1. Then we verify the case where G/Z(G) is abelian. After that, we consider the case where G/Z(G) is non-abelian. We verify this case in three subcases where G/Z(G) is a p-group, a Frobenius group or a 2-Frobenius group. In fact, we show that the only GROUPS which satisfy the intended property are the GROUPS that are attained in the case Z(G)=1 and all of these GROUPS are Frobenius GROUPS.

Abstract: 

The category, or class of algebras, in the title is denoted by W. A hull operator (ho) in W is a reflection in the category consisting of W objects with only essential embeddings as morphisms. The proper class of all of these is hoW. The bounded monocoreflection in W is denoted B. We classify the ho’, s by their interaction with B as follows. A “, word”,is a function w: hoW −, ! WW obtained as a finite composition of B and x a variable ranging in hoW. The set of these, “, Word”, , is in a natural way a partially ordered semigroup of size 6, order isomorphic to F(2), the free 0−, 1 distributive lattice on 2 generators. Then, hoW is partitioned into 6 disjoint pieces, by equations and inequations in words, and each piece is represented by a characteristic order-preserving quotient of Word (,F(2)). Of the 6: 1 is of size ,2, 1 is at least infinite, 2 are each proper classes, and of these 4, all quotients are chains,another 1 is a proper class with unknown quotients,the remaining 1 is not known to be nonempty and its quotients would not be chains.
