Dominants of economic security of Russian industrial organizations with participation of state in capital: chronicles of “Russian Helicopters” holding company

Measures and activities of the Russian state aimed at ensuring the economic security of the "Russian Helicopters" holding company have been considered. The problematic situations in the company’s activities that threaten its stable functioning have been presented. The development of the model range of "Russian Helicopters" in comparison with leading foreign competitors has been reviewed. The technological parity of the holding and competing firms has been diagnosed. The efforts of the Russian state to meet the needs of Russian helicopter builders in aircraft engines and new materials have been described. A group offactors influencing the level of unit cost has been presented. The production results of the holding’s work have been given. It has been concluded about the effectiveness and efficiency of the actions of the management and the state-owner of the company, aimed at protecting its interests.

Spectral representations of topological groups and near-openly generated groups

Near-openly generated groups are introduced. They form a topological and multiplicative subclass of -factorizable groups. Dense and open subgroups, quotients and the Raikov completion of a near-openly generated group are near-openly generated. Almost connected pro-Lie groups, Lindelöf almost metrizable groups and the spaces of all continuous real-valued functions on a Tychonoff space with pointwise convergence topology are near-openly generated. We provide characterizations of near-openly generated groups using methods of inverse spectra and topological game theory. Bibliography: 24 titles.

Sufficient conditions for the solvability of a finite group

In this paper we study factorizable groups. An extension of a famous theorem of H. Wielandt on groups factorizable by two nilpotent subgroups of relatively prime orders is obtained. We also present a variant of a theorem of A. Goncalves and C. Y. Ho.

-factorizability of -spaces in the category G-Tych

We introduce and characterize the notion of -factorizability of -spaces in the category G- Tych. For -spaces with -openly acting groups, we establish the equivalence of -factorizability and -factorizability in G-Tych. We prove the -factorizability in G-Tych of every -factorizable -space with transitive action whose phase space possesses the Baire property. The Dieudonné completion of an -factorizable group is shown to be the phase space of a -space -factorizable in G-Tych. We characterize -factorizability in G-Tych under passage to the -compactification.

On n-multiply σ-local formations of finite groups

Throughout this paper, all groups are finite. Let be some partition of the set of all primes . If n is an integer, the symbol denotes the set ; and . We call any function f of the forma formation σ-function, and we putIf for some formation σ-function f we have , then we say that the class is σ-local and f is a σ-local definition of . We suppose that every formation is 0-multiply σ-local; for n > 0, we say that the formation is n-multiply σ-local provided either is the class of all identity groups or where is multiply σ-local for all . In this paper, we describe some properties and examples of n-multiply σ-local formations. In particular, we prove that the Gaschütz product of any two n-multiply σ-local formations is also n-multiply σ-local. We also consider one application of such formations in the theory of finite factorizable groups.

Magnitude of Clostridium Difficile Infection in Hospitalized Egyptian Patients with Liver Cirrhosis

Background and Aim: Watery diarrhea is the cardinal clinical symptom of Clostridium Difficile infection that causes a spectrum of manifestations ranging from asymptomatic carrier state to severe fulminant disease with toxic megacolon. The basis for symptomatic responses range is related to host and pathogen factors. We studied the prevalence of Clostridium Difficile infection in hospitalized cirrhotic patients and its possible risk factors. Patients and methods: This study was carried out on 200 cirrhotic patients admitted to National Liver Institute hospital divided into 2 groups: 100 asymptomatic patients and 100 patients with diarrhea. Direct stool toxin detection was done using an assay named RIDASCREEN® Clostridium Difficile Toxin A/B test; an enzyme immunoassay (EIA) for the qualitative determination of toxins A and B of Clostridium difficile in stool. Results: Among 200 patients with mean age of (51.81 ± 12.94), EIA revealed 16 and 32 positive cases in both groups. In group I, there was statistical significance in ALT, serum creatinine (p<0.05) and bilirubin level (p<0.01) as regard EIA test result. Also, statistical significance was found (p<0.05) as regard duration of antibiotic and PPI intake. Logistic regression analysis revealed that gender and duration of PPIs use were independent factors in group I while the patient’s age, duration of antibiotic use and γ-GT serum level were independent factors in group II for clostridium difficile infection development. Conclusion: Clostridium difficile infection is not an uncommon infection in hospitalized cirrhotic patients. Risk factors were antibiotic intake, gastric acid suppression, old age, long hospital stay and/or history of bilharziasis.

Significance of Culture in Development of Entrepreneurial Mindsets

Entrepreneurship becomes one of the essential conditions of the survival and development on a competitive market. Stimulation and development of entrepreneurship require activities in various fields. Culture is of major importance for the formation of entrepreneurial mindsets. In this paper, changes within the perception of entrepreneurship and its determinants are analyzed. The author focuses on cultural determinants, taking into consideration different groups of factors. An attempt is taken to identify the features of entrepreneurial culture and to characterize its key attributes, as well as to indicate the ways of forming and developing entrepreneurial culture.

Finite factorizable groups with solvable Kℙ2-subnormal subgroups

The solvability of any finite group of the form G = AB is established under the assumption that the subgroups A and B are solvable and KP2-subnormal in the group G.

On a Factorizable Group with Large Cyclic Subgroups in Factors

We prove the supersolvability of a finite factorizable group G = G 1 G 2 . . .G n with pairwise permutable factors each of which has a cyclic subgroup of odd order H i and |G i : H i | ≤ 2.

Factorizations of Finite Groups into r-Soluble Subgroups with Given Embeddings

such that |Hi : Hi−1| 2 X for all i. In this case, we use the notation H Xsn G . This chain is called an X-supernormal chain for the subgroup H. If X = P, then we get the notion of P-supernormality introduced in the paper [1] devoted to the investigation of the properties of finite groups with P-subnormal Sylow subgroups. The groups with P-subnormal 2-maximum subgroups and the groups with P-subnormal primary cyclic subgroups are described in [2]. If X = P2, then we get the notion of P2 -subnormality. Finite factorizable groups G = AB under the condition that A and B are P2 -subnormal in G were studied in [3]. In particular, Theorem 1 of the present paper establishes the solubility of the group G under the condition that A and B are soluble without using the classification of finite simple groups.

FACTORS INFLUENCING LEISURE TIME PHYSICAL ACTIVITY OF CHILDREN

Grounding of research.Scientific problem discussed in the article-what factors influence children’sleisure time physical activity. Inorder to choose the right means to encourage children to be more physicalactive, it is important to analyse what factors can influence this. Leisure time is an important routine ofchildren’s everyday life, and engaging into physical activities during leisure time brings a lot of benefits.Theproblem isrelevantasit is important to discuss all the aspects related to the ways that could encourage childrenfor physical activity, including the analysis of factors, influencing their leisure time physical activity.Thegoalof research–to analysefactors influencingleisure time physical activity physical activity of children. Objectsof research: To discuss importance of leisure time physical activity for children.To identify groups of factorsimportantfor children leisure time physical activity physical activity. Research object subject–factorsinfluencingleisure time physical activity physical activity of children. Qualitative methods were used in thisarticle, performing comparative analysis of scientific literature. Scientific articles discussing results ofempirical research were chosen for the analysis. Most articles that are analysed were published in 2007–2015.Results of research.Results of research reveal that leisure time physical activity is especially importantfor children for overall benefit of physical activity for their physical and mental health (in childhood and infuture). According to the theories explaining factors influencing leisure time physical activity such groups offactors may be determined: psychosocial factors (internal factors), environmental factors including factors ofsocial support (family, school), physical environment and political factors. Results reveal that psychologicalfactors, such as extraversion, conscientiousness, enjoyment, self-efficacy are related to higher levels ofphysical activity. Gender also matters–boys are usually more physically active that girls (especially there aregreat differences in adolescence). Influence of socioeconomic factors is not obvious (smaller children’sphysical activity does not correlate to financial state of family, but it does in later age). Parents may have greatinfluence on children’s physical activity modelling, encouraging, providing and involving their children withphysical activities. But children’s physical activity is negatively influenced if home surroundings encouragesedentary leisure time activities. Efforts of school to create availability of organized physical activities withsupervision, also rational daytime table, giving children time for being physically active, may have benefit.However neighbourhood environmental and facility factorsare notrelevant to explain children’s andadolescents’ physical activity.Main conclusions of research.1. Physical activity should be a part of leisure time routine, assuringthat children would be physically active daily.2. Two main groups of factors can be treated as significant inaffecting physical activityof children: psychosocial factors, and factors of social support (family, home,school).

Supersolvability of finite factorizable groups with cyclic Sylow subgroups in the factors

Let p be a prime. Under certain additional conditions, we establish the p-supersolvability of a finite p-solvable group G = AB with cyclic Sylow p-subgroups in A and B. In particular, we prove that a finite group G = AB is supersolvable provided that all Sylow subgroups in A and B are cyclic and either G is 2-closed or A and B are maximal subgroups.

Finite factorizable groups with solvable ℙ2-subnormal subgroups

A subgroup H of a finite group G is called ℙ2-subnormal whenever there exists a subgroup chain H = H0 ≤ H1 ≤ ... ≤ Hn = G such that |Hi+1: Hi| divides prime squares for all i. We study a finite group G = AB on assuming that A and B are solvable subgroups and the indices of subgroups in the chains joining A and B with the group divide prime squares. In particular, we prove that a group of this type is solvable without using the classification of finite simple groups.

O que fazer com grupos de fatores não selecionados? O caso da concordância nominal no Paraná

O objetivo deste trabalho é repensar a questão da seleção de grupos de fatores (GFs) pelo pacote Varbrul, a partir de uma divergência ocorrida quando das rodadas com duas cidades do Paraná, Irati e Pato Branco, na análise da concordância nominal. Um dos GFs estruturais, tipos de formação do plural, foi selecionado quando se rodou Irati, mas não em Pato Branco, apesar de a amostra ter sido feita com uma única metodologia, a do Projeto Varsul, e com exatamente os mesmos GFs, tanto os linguísticos, quanto os sociais. Por isso se questiona até que ponto se deve considerar, na análise, somente a seleção dos GFs pelo Varbrul, quando o objetivo de uma amostra, como é o caso, é perscrutar se e até que ponto a ocupação étnica diferenciada (sobretudo na região Sul) poderia interferir em fenômenos da língua portuguesa no Brasil.

On the reconstruction problem for factorizable homeomorphism groups and foliated manifolds

For a group G of homeomorphisms of a regular topological space X and a subset U ⊆ X , set G ▪ : = { g ∈ G | g ↾ ( X ∖ U ) = Id } . We say that G is a factorizable group of homeomorphisms, if for every open cover U of X, ⋃ U ∈ U G ▪ generates G. Theorem I Let G, H be factorizable groups of homeomorphisms of X and Y respectively, and suppose that G, H do not have fixed points. Let φ be an isomorphism between G and H. Then there is a homeomorphism τ between X and Y such that φ ( g ) = τ ○ g ○ τ − 1 for every g ∈ G . Theorem A strengthens known theorems in which the existence of τ is concluded from the assumption of factorizability and some additional assumptions. Theorem II For ℓ = 1 , 2 let ( X ℓ , Φ ℓ ) be a countably paracompact foliated ( not necessarily smooth) manifold and G ℓ be any group of foliation-preserving homeomorphisms of ( X ℓ , Φ ℓ ) which contains the group H 0 ( X ℓ , Φ ℓ ) of all foliation-preserving homeomorphisms which take every leaf to itself. Let φ be an isomorphism between G 1 and G 2 . Then there is a foliation-preserving homeomorphism τ between X 1 and X 2 such that φ ( g ) = τ ○ g ○ τ − 1 for every g ∈ G 1 . In both Theorems I and II, τ is unique.

Dieudonné Completion and PT-Groups

We consider the classes of PT-groups, strong PT-groups, completion friendly groups, and Moscow groups introduced by Arhangel’skii for the study of the Dieudonne completion of topological groups. We show that every subgroup H of a Lindelof P-group is a PT-group, and that H is a strong PT-group iff it is \({\mathbb R}\)-factorizable. Assuming CH, we prove that every ω-narrow P-group is a PT-group. Several results regarding products of PT-groups and \({\mathbb R}\)-factorizable groups are established as well. We prove that the product of a Lindelof group and an arbitrary subgroup of a Lindelof Σ-group is completion friendly, and the same conclusion is valid for the product of an \({\mathbb R}\)-factorizable P-group with an almost metrizable group.

MULTIPLICITIES IN SYLOW SEQUENCES AND THE SOLVABLE RADICAL

AbstractA complete Sylow sequence, 𝒫=P1,…,Pm, of a finite group G is a sequence of m Sylow pi-subgroups of G, one for each pi, where p1,…,pm are all of the distinct prime divisors of |G|. A product of the form P1⋯Pm is called a complete Sylow product of G. We prove that the solvable radical of G equals the intersection of all complete Sylow products of G if, for every composition factor S of G, and for every ordering of the prime divisors of |S|, there exist a complete Sylow sequence 𝒫 of S, and g∈S such that g is uniquely factorizable in 𝒫 . This generalizes our results in Kaplan and Levy [‘The solvable radical of Sylow factorizable groups’, Arch. Math.85(6) (2005), 490–496].

Finite simple groups with complemented maximal subgroups

We study Problem 8.31 in [1] of the description of finite weakly factorizable groups, i.e., the groups whose every proper subgroup is complemented in a larger subgroup. By Lemma 1 of [2], the subdirect product of a completely factorizable group (such groups were studied by Ph. Hall and N. V. Baeva (Chernikova)) and a weakly factorizable group is a weakly factorizable group. In connection with a remark in [2], we observe that a dihedral 2-group is always weakly factorizable but, in general, it cannot even be obtained from the groups of prime order by repeated application of the lemma. Theorem 1, basing on the available maximal factorizations, shows that there exist exactly three finite simple nonabelian groups with complemented maximal subgroups. Theorem 2 confirms the conjecture of [2] on uniqueness of a finite simple nonabelian group with the property of weak factorizability. Earlier Theorems 1 and 2 were proven in special cases by A. G. Likharev.

The solvable radical of Sylow factorizable groups

Let G be a finite group. A complete Sylow product of G is a product of Sylow subgroups of G, one for each prime divisor of |G|. We shall call G a Sylow factorizable group if it is equal to at least one of its complete Sylow products. We prove that if G is a Sylow factorizable group then the intersection of all complete Sylow products of G is equal to the solvable radical of G. We generalize the concepts and the result to Sylow products which involve an arbitrary subset of the prime divisors of |G|.
