we call $h$ an $ss$-embedded subgroup of $g$ if there exists a‎ ‎normal subgroup $t$ of $g$ such that $ht$ is subnormal in $g$ and‎ ‎$hcap tleq h_{sg}$‎, ‎where $h_{sg}$ is the maximal $s$-permutable‎ ‎subgroup of $g$ contained in $h$‎. ‎in this paper‎, ‎we investigate the‎ ‎influence of some $ss$-embedded subgroups on the structure of a‎ ‎finite group $g$‎. ‎some new results were obtained.‎

Among other things, we prove that the group of automorphisms fixing every normal subgroup of a (nilpotent of class c)-by-abelian group is (nilpotent of class ≤ c)-by-metabelian. In particular, the group of automorphisms fixing every normal subgroup of a metabelian group is soluble of derived length at most 3. An example shows that this bound cannot be improved.

OBJECTIVE To investigate the roles of inflammation and a cholesteryl ester transfer protein (CETP) polymorphism potentially related to recent findings demonstrating coronary risk with increasing high-density lipoprotein cholesterol (HDL-C) level. METHODS AND RESULTS A novel graphical exploratory data analysis tool allowed the examination of coronary risk in postinfarction patients relating to...

objective(s) the effect of berberis vulgaris aqueous extract in hepatocarcinogenic rats was studied to investigate the apoptotic and sodium, potassium elements properties. a loss of both intracellular potassium and sodiumoccurs when apoptotic cells shrink and prior to the loss of membraneintegrity. materials and methods forty-eight sprague dawley rats were randomly divided into 2 groups, normal...

Background: Cucumber mosaic virus (CMV) from the Bromoviridae family, is one of the most widespread plant viruses in the world. Objectives: In the present study tomato fields in Guilan, Isfahan, Khorasan Razavi, Khuzestan and Tehran provinces were surveyed to determine the presence of CMV subgroups during 2011-2012. Materials and Methods: Out of 305 symptomatic leaf samples ...

Let G be a group and let Autc(G) be the group of central automorphisms of G. We say that a subgroup H of a group G is c-characteristic if α(H) = H for all α ∈ Autc(G). We say that a group G is c-characteristically simple group if it has no non-trivial c-characteristic subgroup. If every subgroup of G is c-characteristic then G is called co-Dedekindian group. In this paper we characterize c-char...

With the aim of establishing optimal dosage schedules, 171 women with either overt (OH, n = 80) or subclinical (SCH, n = 91) hypothyroidism were assessed before and 6 months after starting L-thyroxine (LT4) replacement therapy. Each group was further classified into four subgroups according to post-therapy serum TSH level, as follows: A) complete suppression; B) partial suppression; C) normal r...

Lattices and parabolic subgroups are the obvious examples of cocompact subgroups of a connected, semisimple Lie group with finite center. We use an argument of C. C. Moore to show that every cocompact subgroup is, roughly speaking, a combination of these. We study a cocompact subgroup H of a connected, semisimple Lie group G with finite center. The case where H is discrete is very important and...

Ctenosaura oedirhina is described from specimens formerly referred to C. bakeri collected on Isla de Roatán, Honduras. A phylogenetic analysis of relationships within Ctenosaura based on 21 morphological characters indicates that although the new species is part of a monophyletic subgroup also containing C. bakeri, C. clarki, C. defensor, C. palearis, and C. quinquecarinata, it may not be the c...
