in this paper we give a new condition for a sylow $p$-subgroup of a finite group to control transfer. then it is deduced a characteri-zation of supersoluble groups that can be seen as a generalization of the well known result concerning the supersolubility of finite groups with cyclic sylow subgroups. moreover a condition for a normal embedding of a strongly closed $p$-subgroup is given. ...
a noninteracting quantum-dot arrays side coupled to a quantum wire is studied. transport through the quantum wire is investigated by using a noninteracting anderson tunneling hamiltonian. the conductance at zero temperature develops an oscillating band with resonances and antiresonances due to constructive and destructive interference in the ballistic channel, respectively. moreover, we have fo...
in this paper we introduce the notion of classical quasi-primary submodules that generalizes the concept of classical primary submodules. then, we investigate decomposition and minimal decomposition into classical quasi-primary submodules. in particular, existence and uniqueness of classical quasi-primary decompositions in finitely generated modules over noetherian rings are proved. moreover, w...
total or partial absence or excess of the sex chromosomes produces different karyotypes and phenotypical abnormalities. upon retrospective analysis of the results of 163444 cytogenetic tests that were performed during 28 years (1987-2015) in this center, different types of sex chromosomal aberrations and the clinical phenotypes are delineated in this article. moreover, the clinical course and t...
we discuss here an uncommon condition of neurogenic hypotension in the context of immunoglobulin light chain (amyloid light-chain) amyloidosis. th e most serious feature was autonomic nervous system impairment, mainly characterized by severe refractory orthostatic hypotension, which became progressively invalidating, forcing the patient to bed. moreover, since the systemic involvement of the di...
in this paper we give a characterization for all semigroups whose square is a group. moreover, we axiomatize such semigroups and study some relations between the class of these semigroups and grouplikes,introduced by the author. also, we observe that this paper characterizes and axiomatizes a class of homogroups (semigroups containing an ideal subgroup). finally, several equivalent conditions ...
amelanotic melanoma is a variant of malignant melanoma comprising 2% to 8% of all malignant melanomas. the amelanotic presentation of melanoma in the oral cavity is extremely rare and has been reported only occasionally in the literature. moreover, the lack of melanin makes these tumors difficult to diagnose than that of pigmented lesions and the prognosis tends to be poorer. herein, we report ...
silver nanoparticles have proved to possess significant antibacterial properties. nanosilver produced by electrochemical reduction stabilized by cellulose derivatives, has been evaluated by european standards (cen tc 216) in order to find out whether they could be applied in food, industrial, domestic and institutional areas as a suitable disinfectant. moreover, bactericidal activity of nanosil...
in this paper, tripled coincidence points of mappings satisfying -contractive conditions in the framework of partially ordered gb-metric spaces are obtained. our results extend the results of aydi et al. [h. aydi, e. karapnar and w. shatanawi, tripled xed point results in generalized metric space, j. applied math., volume 2012, article id 314279, 10 pages]. moreover, some examples of the mai...
the matrix functions appear in several applications in engineering and sciences. the computation of these functions almost involved complicated theory. thus, improving the concept theoretically seems unavoidable to obtain some new relations and algorithms for evaluating these functions. the aim of this paper is proposing some new reciprocal for the function of block anti diagonal matrices. more...
