We discuss resonance properties in three-body systems, with examples on $$^{12}{\mathrm C}$$ and $$^{24}\mathrm{Mg}$$ . use a microscopic cluster model, where the generator coordinate is defined hyperspherical formalism. The nucleus described by an $$\alpha +\alpha $$ structure, whereas considered as $$^{16}\mathrm{O}+\alpha system. essentially pay attention to resonances. review various techni...

Intra-ovarian regulation of follicular maturation is modulated by various factors. Among these, growth factors are important local actors. We examined the immunohistochemical localization of transforming growth factor alpha (TGF-alpha), epidermal growth factor (EGF) and epidermal growth factor receptor (EGF-R) in 18 human ovaries. The concentration of TGF-alpha and EGF in follicular fluid was m...

alpha-L-fucose abolishes the activity of guinea pig migration inhibitory factor (MIF) on the macrophages. Other sugars such as alpha-D-glucose, beta-D-galactose, alpha-L-rhamnose, methyl-alpha-D-mannoside, and N-acetyl-beta-D-glucosamine had no effect. Theabolition of MIF activity by alpha-L-fucose was reversible. When macrophages were incubated with alpha-L-fucosidase, a glycosidase which spli...

Given a finite and connected two-dimensional CW complex K with fundamental group $$\Pi $$ second integer cohomology $$H^2(K;\mathbb {Z})$$ of odd order, we prove that: (1) for each local coefficient system $$\alpha :\Pi \rightarrow \textrm{Aut}(\mathbb over K, the corresponding twisted $$H^2(K;_{\alpha }\!\mathbb is say order $$\mathfrak {c}^{*}(\alpha )$$ , there exists natural function—which ...

The submodules with the property of the title ( a submodule $N$ of an $R$-module $M$ is called strongly dense in $M$, denoted by $Nleq_{sd}M$, if for any index set $I$, $prod _{I}Nleq_{d}prod _{I}M$) are introduced and fully investigated. It is shown that for each submodule $N$ of $M$ there exists the smallest subset $D'subseteq M$ such that $N+D'$ is a strongly dense submodule of $M$ and $D'bi...

Fix a finite ordinal \(n\geq 3\) and let \(\alpha\) be an arbitrary ordinal. Let \(\mathsf{CA}_n\) denote the class of cylindric algebras dimension \(n\) \(\sf RA\) relation algebras. \(\mathbf{PA}_{\alpha}(\mathsf{PEA}_{\alpha})\) stand for polyadic (equality) \(\alpha\). We reprove that \(\mathsf{CRCA}_n\) completely representable \(\mathsf{CA}_n\)s, CRRA\) \(\mathsf{RA}\)s are not elementary...

in this paper, we introduce the dual notion of strongly top modules and study some of the basic properties of this class of modules.

Aim: The aim of the study was to determine Czech nursing and midwifery students’ perception of the effectiveness of evidence-based practice (EBP) courses. Another objective was to verify the psychometric properties of a Czech version of the Perception of Effectiveness of EBP Courses questionnaire. Design: A descriptive cross-sectional study. Methods: The Czech version of the 13-item instrument ...
