An analytical system based on rRNA-targeted reverse transcription-quantitative PCR (RT-qPCR) for enumeration of catalase-negative, Gram-positive cocci was established. Subgroup- or species-specific primer sets targeting 16S or 23S rRNA from Enterococcus, Streptococcus, and Lactococcus were newly developed. The RT-qPCR method using these primers together with the previously reported primer sets ...

In this article we introduce the notion of n-capable groups. It is shown that every group G admits a uniquely determined subgroup (〖Z^n)〗^* (G) which is a characteristic subgroup and lies in the n-centre subgroup of the group G. This is the smallest subgroup of G whose factor group is n-capable. Moreover, some properties of n-central extension will be studied.

SOME systems of collineation groups which arise in connection with the theory of elliptic functions have been investigated by Klein | and HurwitzJ. One of them is a system in n variables each group of which contains an invariant subgroup of order n. For n SL prime the quotient group with respect to this invariant subgroup is (1, 1) isomorphic with the modular group on two indices of order n(n —...

INTRODUCTION Exposure to tobacco smoke is an extremely important risk factor determining the development of respiratory diseases, cardiovascular diseases and cancer. Passive exposure is common and often not realized by the exposed subjects. Markers of tobacco smoke exposure are nicotine metabolites, i.e. cotinine and trans-3'-hydroxycotinine. OBJECTIVES The objective of the study was to asses...

 ‎Let $tilde{F}=(Q,S,tilde{R},Z,omega,tilde{delta},‎ F_1,F_2)$‎ ‎be a general fuzzy automaton and the set of its states be a group.‎ ‎The aim of this paper is the study of applications of a group in a‎ ‎general fuzzy automaton‎. ‎For this purpose‎, ‎we define the concepts‎ ‎of fuzzy normal kernel of a general fuzzy automaton‎, ‎fuzzy kernel‎ ‎of a general fuzzy automaton‎, ‎adjustable‎, ‎multip...

objective: the main aim of this study was to investigate the psychological and social adjustment of parents whose adolescent children had experienced a disaster. mediating factors were considered; such as whether the child developed post-traumatic stress disorder (ptsd), dysfunctional attitudes, other intervening life events, and especially, social support. method: participants were 37 women wh...

Let t, be r-dimensional real projective space with r odd, and let irnDiff* : Pr be the group of orientation preserving difteomorphisms P,-* P, factored by the normal subgroup of those concordant (= pseudoiso topic) to the identity. The main theorem of this paper is that fores 11 mod 16 the group T0Diff+: P, is isomorphic to the homotopy group irr+i+k(&/Pk-\), where k dlL r 1 with L > <p((r + l)...

We provide a Rademacher theorem for intrinsically Lipschitz functions \(\phi\colon U\subseteq\mathbf{W}\to\mathbf{L}\), where \(U\) is Borel set, \(\mathbf{W}\) and \(\mathbf{L}\) are complementary subgroups of Carnot group, we require that normal subgroup. Our hypotheses satisfied example when horizontal Moreover, an area formula this class functions.
