Human development index - the influencing factors, ways of development on the example of Russia and the countries of the former Soviet Union
According to the name of article, in it dynamics of an Human Development index over the countries of the former Soviet Union is considered. Lagging of Russia from the leading countries is especially noted, comparison is carried out them. Also Years of Life Lost index is mentioned in article, its influence on human development is specified. Much attention is paid to prospects of development of the country in all directions which influence HDI. In the conclusion a number of open questions which our state should solve is emphasized
Two-Component Dust in Spherically Symmetric Motion
Two components of spherically symmetric, inhomogeneous dust penetrating each
other are introduced as a generalization of the well-known Tolman-Bondi dust
solution. The field equations of this model are formulated and general
properties are discussed. inhomogeneous Special solutions with additional
symmetries - an extra Killing- or homothetic vector - and their matching to the
corresponding Tolman-Bondi solution are investigated.Comment: 16 pages, LaTeX, 5 figures, accepted for publication in Class.

Development of Complex Mathematical Model of Light Naphtha Isomerization and Rectification Processes
The technique of developing a mathematical model of catalytic isomerization of light naphtha is stated Using experimental data from an industrial isomerization unit shows adequacy of the mathematical model to the real process. The paper presents a method for optimizing the operation of the plant together with catalytic isomerization unit and separation columns. Selection of optimal modes of separation columns allows achieving the desired flow separation between units, as well as extension of the life of the catalyst SI-2
Self-Similarity in General Relativity \endtitle
The different kinds of self-similarity in general relativity are discussed,
with special emphasis on similarity of the ``first'' kind, corresponding to
spacetimes admitting a homothetic vector. We then survey the various classes of
self-similar solutions to Einstein's field equations and the different
mathematical approaches used in studying them. We focus mainly on spatially
homogenous and spherically symmetric self-similar solutions, emphasizing their
possible roles as asymptotic states for more general models. Perfect fluid
spherically symmetric similarity solutions have recently been completely
classified, and we discuss various astrophysical and cosmological applications
of such solutions. Finally we consider more general types of self-similar
models.Comment: TeX document, 53 page
Cognitive Profile of Students Who Enter Higher Education with an Indication of Dyslexia
For languages other than English there is a lack of empirical evidence about the cognitive profile of students entering higher education with a diagnosis of dyslexia. To obtain such evidence, we compared a group of 100 Dutch-speaking students diagnosed with dyslexia with a control group of 100 students without learning disabilities. Our study showed selective deficits in reading and writing (effect sizes for accuracy between d = 1 and d = 2), arithmetic (d≈1), and phonological processing (d>0.7). Except for spelling, these deficits were larger for speed related measures than for accuracy related measures. Students with dyslexia also performed slightly inferior on the KAIT tests of crystallized intelligence, due to the retrieval of verbal information from long-term memory. No significant differences were observed in the KAIT tests of fluid intelligence. The profile we obtained agrees with a recent meta-analysis of English findings suggesting that it generalizes to all alphabetic languages. Implications for special arrangements for students with dyslexia in higher education are outlined
Monitoreo del progreso del alumno en la identificación de riesgo en la lectura
Este estudo tem por nalidade analisar o uso da monitorização com base no currículo como sistema escolar de identi cação de alunos em risco na leitura, no contexto de um modelo educativo baseado no grau de resposta à intervenção. Realizou-se uma investigação quantitativa em que participaram todos os alunos do 3o ano (82 alunos) de um agrupamento de escolas do norte de Portugal. O tratamento de dados foi feito com recurso à estatística descritiva e inferencial. Destacam-se, entre outras conclusões, a existência de dez alunos em risco na leitura durante todo o ano letivo e o facto de, no nal do 3o ano de escolaridade, a média de resultados dos alunos que nunca estiveram em risco ser superior ao dobro da média de resultados dos alunos que estiveram em risco todo o ano.This study aims to analyze the use of curriculum-based monitoring as a school
system to identify students at risk in reading, in the context of an educational
model based on the degree of response to intervention. A quantitative investigation
was conducted with all third grade students (82 students) from a group of
schools in the north of Portugal. Data processing was done using descriptive and
inferential statistics. Among the conclusions, the following stand out: the existence
of ten students at risk in reading throughout the school year and the fact that, at
the end of the third year of schooling, the mean results of students who were never
at risk was more than double the mean results of students who were at risk for the
entire year.Cette étude a pour but d’analyser l’usage du contôle ayant pour base le coursus
comme système scolaire d’identification des élèves présentant des risques dans la
lecture, dans le contexte d’un modèle éducatif fondé sur le degrée de réponse à
l’intervention. On a fait une investigation quantitative à laquelle ont participé tous
les élèves de CM1 (82 élèves) d’un groupement d’écoles du nord du Portugal. Le
traitement des données a été fait à l’aide de la statistique descriptive et inférentielle.
On souligne, entre autres conclusions, l’existence de dix élèves en risque dans la
lecture pendant toute l’année scolaire et le fait qu’à la fin de la troisièmme année
de scolarité, la moyenne des résultats des élèves n’ayant jamais été en risque soit
supérieur au double de la moyenne des résultats des élèves qui ont été en risque
toute l’année.Este estudio tiene la finalidad de analizar el uso del monitoreo del currículo como

Symmetries of Nonlinear Telegraph Equations in Strong Fields
In this article the symmetries of a class of nonlinear telegraph equations are examined. These equations represent a physical model describing electro magnetic shock waves. The main interest is concentrated on potential symmetries but Lie point and non classical symmetries are also calculated. With the aid of these symmetries explicit new solutions are derived or given implicitly by defining equations
