The optimal design of cables under selfweight and concentrated loads is considered and the maximum feasible span for a given permissible stress is evaluated. All solutions are obtained in a closed analytical form.

_ Source: _Volume 40, Issue 1, pp 104 - 115 It is intended in this study to present initial reliability and validity data for the Russian adaptation of the Multidimensional Inventory of Religious/Spiritual Well-being, as being related to personality factors and psychopathology. Therefore, the first version of the MI-RSWB-R was applied to a sample of 192 non-clinical subjects, together with the NEO Five Factor Inventory and the Symptom-Check-List. The original six-factor structure of the scale could be replicated for the MI-RSWB-R, (...) which also provides satisfying psychometric properties. In accordance with previous research the RSWB total score was linked to more favorable personality traits such as Extraversion, Openness to Experience, and Agreeableness, which was paralleled by substantial negative correlations with increased psychopathology. Our findings support the reliability and structural validity of the MI-RSWB-R as a standardized instrument for addressing the spiritual dimension in Russian populations. Further research in clinical surroundings is now recommended. (shrink)

To base oneself upon a scientific philosophy is often of great importance in framing and solving major problems in natural science, including the science of the universe at large. Moreover, one's approach to the solution of specific problems arising in natural science depends to an extent upon one's philosophy. This situation points the way to the elimination of certain preconceived notions and erroneous convictions of researchers, that is, those due to an inadequate knowledge of philosophy or to the influence of (...) a weak philosophy.

This article contains the proof of equivalence boolean algebra and syllogistics arc2. The system arc2 is obtained as a superstructure above the propositional calculus. Subjects and predicates of syllogistic functors a, E, J, O may be complex terms, Which are formed using operations of intersection, Union and complement. In contrast to negative sentences the interpretation of affirmative sentences suggests non-Empty terms. To prove the corresponding theorem we demonstrate that boolean algebra is included into syllogistics arc2 and vice versa.

One of the most important philosophical principles in contemporary natural science is the principle of the universality of evolutionary development , which was argued with much force and depth in F. Engels's The Dialectics of Nature. For the more than a century that has passed since Engels's sweeping synthesis of knowledge in the natural sciences, his revelation of the unity of the processes of evolution in inanimate and animate nature, including the inevitably and law-governed appearance of its "highest flower, the (...) thinking mind," where appropriate conditions for that appearance arise, this principle of development has assisted in the achievement of many impressive advances. The general outlines of the evolutionary process of nature, in its infinite diversity, are now emerging in ever sharper relief, although our knowledge of that process still contains many rather serious lacunae. It is significant to note that the progress of natural science leads not only to modifications but often even to radical revisions of many notions about the evolution of nature, including those that seemed unchallengeable.

After the First Conference, the situation with regard to the relation between natural scientists and philosophers improved considerably in the sense that, as we can see, philosophers, by their work on questions of methodology, are helping natural scientists more and more, while natural scientists are giving increasing attention to the results of the work of philosophers, and are becoming interested in the philosophical conclusions following from their research and in general problems of philosophical significance.
