this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...

let h be a subgroup of a group g. h is said to be s-embedded in g if g has a normal t such that ht is an s-permutable subgroup of g and h ∩ t ≤ h sg, where h denotes the subgroup generated by all those subgroups of h which are s-permutable in g. in this paper, we investigate the influence of minimal s-embedded subgroups on the structure of finite groups. we determine the structure the finite grou...

Let $G$ be a finite group. A subgroup $H$ is called $S$-semipermutable in if $HG_p$ = $G_pH$ for any $G_p\in Syl_p(G)$ with $(|H|, p) 1$, where $p$ prime number divisible $|G|$. Furthermore, said to $NH$-embedded there exists normal $T$ of such that $HT$ Hall and $H \cap T \leq H_{\overline{s}G}$, $H_{\overline{s}G}$ the largest contained $H$, $SS$-quasinormal provided supplement $B$ permutes e...

A subgroup H of a group G is called ss-quasinormal in G if there is a subgroup B of G such that G = HB and H permutes with every Sylow subgroup of B; H is called weakly s-permutable in G if there is a subnormal subgroup T of G such that G = HT and H ∩ T ≤ HsG, where HsG is the subgroup of H generated by all those subgroups of H which are s-permutable in G. We fix in every non-cyclic Sylow subgr...

Abstract A group is called quasihamiltonian if all its subgroups are permutable, and we say that a subgroup Q of G permutably embedded in $\langle Q,g\rangle $ for each element g . It proved here contains normal such $G/Q$ ?ernikov, then has finite index; moreover, periodic, it ?ernikov N $G/N$ quasihamiltonian. This result should be compared with theorems Schlette stating over centre, abelian-...

INTRODUCTION A subgroup of patients with primary Sjögren's Syndrome (SS) and positive anticentromere antibodies (ACA) were recognized as having features intermediate between SS and systemic sclerosis (SSc). Our goal was to describe this group clinically and serologically and define its tendency to evolve to full blown SSc. METHODS Among 535 patients with primary SS we identified 20 ACA positi...

Aim: Testicular torsion which is the most common cause of acute scrotum, a real surgical emergency. However, despite imaging techniques and laboratory studies used in differential diagnosis pathologies causing difficult. Therefore, there need for parameters that confirm testicular torsion.In our study, we aimed to investigate usability as parameter scrotum inflammation children via thiol-disulf...

introduction: the aim of this study was to evaluate the amount of dentine removed after canal preparation using stainless steel (ss) hand instruments or rotary profile instruments. materials and methods: thirty-six extracted human teeth with root canal curvatures less than 30º were embedded in clear polyester resin. the roots were cut horizontally at apical 2, 4 and 7 mm. dentin thickness was m...

OBJECTIVE To determine the prevalence of sicca symptoms and Sjögren's syndrome (SS) in a 2-center prospective series of patients with systemic sclerosis (SSc), using the American-European Consensus Group criteria for SS. METHODS Consecutive SSc patients hospitalized for followup care were evaluated for sicca symptoms. When the initial clinical evaluation yielded positive findings, a labial sa...
