Subject:
modernization and Girirāj Kiśor
Language:
English
Description:
The social-psychological Hindi play Narmedh (1970), written by Girirāj Kiśor, has as its main character a woman wnose husband and sons break with tradition in regard to marriage. Because of her own experiences. she wisches to maintain her family but at the same time she feels guilty about those efforts, and tries to commit suicide. Besides its content, the play is interesting because it is a tragedy, a genre that is more common in European than in Indian literature. The article analyses the techniques of the play and their contribution to the effect of tragedy, and uses especially the method of dialogue anylysis. In the interprearion argued here, the play suggests that after 1947 the old norms ruling personal relationships have been abandoned in favor of an attitude of self-interest or in some cases idealism, without new ones immediately replacing them. The effect is that these relationships may be ruled by indifference, which harms and to some extent immobilizes those who are sensitive.

math and almost $f$-algebra orthosymmetric bimorphism
Language:
English
Description:
Let $A$ and $B$ be two Archimedean vector lattices and let $( A^{\prime }) _n'$ and $( B') _n'$ be their order continuous order biduals. If $\Psi \colon A\times A\rightarrow B$ is a positive orthosymmetric bimorphism, then the triadjoint $\Psi ^{\ast \ast \ast }\colon ( A') _n'\times ( A') _n'\rightarrow ( B') _n'$ of $\Psi $ is inevitably orthosymmetric. This leads to a new and short proof of the commutativity of almost $f$-algebras.

Description:
BACKGROUND: The presence of several risk factors (genetic and non-genetic) has greater impact on the risk of premature coronary artery disease (CAD) than single risk factor. OBJECTIVE: The aim of the study was to establish possible relations between genotypes and alleles of 677C>T polymorphism of MTHFR gene and some traditional risk factors e.g. elevated levels of lipid parameters and smoking in development of premature CAD. METHODS: The groups comprised 152 patients with angiographically documented premature CAD (aged 42.9 +/- 5.5) and 121 age-matched blood donors (aged 42.3 +/- 6.5) were studied. The MTHFR 677C>T polymorphism was genotyped with Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) method. RESULTS: Patients with TT genotype who simultaneously smoked had increased risk of premature CAD compared to non-smoking cases with CC genotype (OR = 24.62). We also found that individuals with TT genotype and elevated LDL-cholesterol (LDL-chol.) level had significantly higher risk of CAD (OR = 9.92) than individuals with normal LDL-chol. level and CC genotype. CONCLUSIONS: The present study shows that simultaneous presence of MTHFR TT genotype and smoking or elevated levels of LDL-chol. influences the risk of premature CAD. This findings give interesting contribution to gene-environment interaction problem that may have clinical implications in the future. and B. Sarecka-Hujar, I. Zak, J. Krauze

Chrysopidae, Dichochrysa prasina, Tetranychus urticae, temperature, alternative prey, and lacewings
Language:
English
Description:
The predatory lacewing Dichochrysa prasina Burmeister can feed and reproduce on various aphid species. However, other species such as the two spotted spider mite Tetranychus urticae Koch may serve as an alternative prey for this predator in the field in periods when the population density of aphids is low. In peach orchards in Northern Greece D. prasina larvae are often found during the summer months on leaves infested with T. urticae. The development and reproduction of D. prasina fed on T. urticae at a series of different constant temperatures were studied. The percentages of D. prasina larvae that completed their development when fed on T. urticae ranged from 12 to 60% depending on the temperature over the range from 20 to 30°C, whereas at temperatures above 33°C no larvae survived. Longevity and egg production of D. prasina females fed during the larval stages on T. urticae were also determined and certain demographic parameters such as the intrinsic rate of increase (rm), mean generation time and net reproductive rate were estimated. Over the range of temperatures from 20 to 27°C, the rm values were not significantly different and varied from 0.06629 to 0.07030. Based on the results of the present study, the possible effect of the availability of T. urticae as prey for D. prasina during summer, when its main prey species is scarce, is discussed.

Description:
Let $\varphi _1,\dots ,\varphi _n$ be real homogeneous functions in $C^\infty (\mathbb R^n-\lbrace 0\rbrace )$ of degree $k\ge 2$, let $\varphi (x) =(\varphi _1(x),\dots ,\varphi _n(x))$ and let $\mu $ be the Borel measure on $\mathbb R^{2n}$ given by \[ \mu (E) =\int _{\mathbb R^n}\chi _E(x,\varphi (x))\, |x|^{\gamma -n}\mathrm{d}x \] where $\mathrm{d}x$ denotes the Lebesgue measure on $\mathbb R^n$ and $\gamma >0$. Let $T_\mu $ be the convolution operator $T_\mu f(x)=(\mu *f)(x)$ and let \[ E_\mu =\lbrace (1/p,1/q)\:\Vert T_\mu \Vert _{p,q}<\infty ,\hspace{5.0pt}1\le p, \,q\le \infty \rbrace . \] Assume that, for $x\ne 0$, the following two conditions hold: $\det ({\mathrm d}^2\varphi (x) h)$ vanishes only at $h=0$ and $\det ({\mathrm d} \varphi (x)) \ne 0$. In this paper we show that if $\gamma >n(k+1)/3$ then $E_\mu $ is the empty set and if $\gamma \le n(k+1)/3$ then $E_\mu $ is the closed segment with endpoints $D=\bigl (1-\frac{\gamma }{n(k+1)},1-\frac{2\gamma }{n(k+1)}\bigr )$ and $D^{\prime }=\bigl (\frac{2\gamma }{n(1+k)},\frac{\gamma }{n(1+k)}\bigr )$. Also, we give some examples.

15368. The Ukrainian factor of the Prague Spring?: Petro Shelest and the Czechoslovak year 1968 in the light of documents of the Ukrainian security service

Ukraine, Czechoslovakia, Prague Spring 1968, Petro Shelest, Soviet intervention, and KGB
Language:
English
Description:
Petro Shelest (1908–1997), the First Secretary of the Communist Party of the Ukrainian Soviet Socialist Republic and a member of the Politburo of the Central Committee of the Communist Party of the Soviet Union, was one of the strongest advocates of an armed invasion of Czechoslovakia among Soviet leaders in 1968. The Soviet leadership tasked him to maintain contacts with the so-called healthy forces in the Communist Party of Czechoslovakia; in the beginning of August, Secretary of the Central Committee of the Communist Party of Czechoslovakia Vasil Biľak (1917–2014) secretly handed over to him the notorious “letter of invitation” in public lavatories in Bratislava. The author asks a fundamental question whether it is possible to identify a specific Ukrainian factor which stepped into the Prague Spring process and contributed to its tragic end. He attempts to capture Shelest’s position in the decision-making process and describe information that Shelest was working with., To this end, he has made use of reports of the Committee for State Security (Komitet gosudarstvennoi bezopasnosti – KGB) of the Ukrainian Soviet Socialist Republic on developments in Czechoslovakia and reactions thereto among Ukrainian citizens produced in the spring and summer of 1968, which were being sent to Shelest and other Ukrainian leaders. These documents have lately been made available in Ukrainian archives and partly published on the website of the Institute for the Study of Totalitarian Regimes. Their analysis brings the author to a conclusion that they were offering a considerably distorted picture of the situation. Instead of relevant information and analyses, they only present various clichés, ideological rhetoric, inaccuracies, or downright nonsenses. Their source were often members of the Czechoslovak State Security who were often motivated by worries about their own careers and existence and were acting on their own., and The uncritical acceptance of the documents contributed to a situation in which in the leader of the Ukrainian Communists and other Soviet representatives were creating unrealistic pictures of the events taking place in Czechoslovakia, believing that anti-socialist forces were winning, anti-Soviet propaganda was prevailing, and Western intelligence agencies were strengthening their position in Czechoslovakia, and that there was a threat that the events that had taken place in Hungary in 1956 would repeat themselves again. As indicated by his published diary entries and other documents, Petro Shelest was using these allegations both in discussions inside his own party and during negotiations with Czechoslovak politicians. Just like in the case of the leaders of Polish and East German Communists, Władysław Gomułka and Walter Ulbricht, respectively, the principal reason why Shelest was promoting a solution of the Czechoslovak crisis by force was, in the author’s opinion, his fear of “contagion” of his own society by events taking place in Czechoslovakia which the Ukraine shared a border with.

Subject:
Agent crawlers, ontology, formal concept analysis, concept similarity, and degree of understanding
Language:
English
Description:
Ontology is widely used in the computer domain to structure concepts that represent a view of world nowadays, which could formally specify semantic relationship among the terms. In this paper, we present coordination between agent crawlers based on ontology in Topic Specific Search Engines, and we try to measure understanding among them, relying on Formal Concept Analysis (FCA) instead of comparing the terms only. In literature, most papers on concept similarity in FCA are based on two different concepts in the same concept lattice, and whereas there is very little research related to different concept lattices or even different agents. We propose a novel method on concept similarity for computing the Concept-Concept similarity, the Concept-Ontology similarity and the Ontology-Ontology similarity, and at last we can deduce understanding among agent crawlers. Finally, we can guide the crawlers effectively in our Search Engine.
