Authors: Sener Bora , Yurci Mehmet Emin 
Published: February 2018

Abstract
The effects of anisotropic yield functions on plastic behavior of 304 stainless steel were investigated in this study. Two yield functions were considered: Hill’48 and Barlat89. Uniaxial tensile tests were carried out 0°, 45°, and 90° from the rolling direction to determine the mechanical properties of the material. The planar distributions of yield stress and the anisotropy coefficient were predicted using the yield models and compared with the experimental results. Subsequent yield surfaces of Hill’48 and Barlat89 were investigated and compared with each other. Deep drawing of a double bowl sink and its simulation were carried out in order to evaluate the prediction ability of the two functions under complex loading conditions. It has been observed that predicted results from Barlat89 criterion showed good agreement with experimental data.
Sumarokov А. М. Renewal of biotic potential of biogeocenoses at reduction in pesticide loadings. – Donetsk, 2009. – 194 p.

Published: February 2018

Maintenance of ecological balance is an important aspect of rational nature management, environmental protection, human health preservation. It is known that a pesticidal press is a substantial ecological factor affecting the structure and the elements of cenosis. However, estimation of the state of cenoses and predicting their response on the anthropogenic influences are often difficult, and sometimes are simply impossible for lack of data on many directions of anthropogenic influence, including in pesticide loadings. In this connection, the monograph of А. М. Sumarokov appears as an extremely actual one, because it fills in the blank of our knowledge on the indicated issue. During many years, including the time of wide use of pesticides (1983–1989) and the period of considerable reduction of their use (1999–2005), the author was conducting the study of comparative species composition and ecological structure of herpetobiont Coleоptera in the main cenosis of Ukrainian steppe zone. The results of the long-term regular field stationary watching the state of koleopterofauna are unique not only for Ukraine but also for all space of the former USSR. The conclusions of the author bring a substantial contribution to entomology, in particular to impression and formation of entomocomplexes of agrocenoses and adjoined biogeocenosis. It is convincingly shown by the author, that the intensification of agricultural production, based on wide-range application of pesticides, reduces the biotic potential of biogeocenoses catastrophically. Thus, the reduction of the use of pesticides does not cause the height of losses of harvest of basic agricultural crops; obviously, it is related to strengthening of regulator activity of etnomofags, the closeness of that in the second period of researches grew more than in 10 times as compared to the first period. In addition, through the analysis of the findings А. М. Sumarokov made the row of interesting theoretical substantiations, in particular, about coenotic status of agrobiocenoses considered by the author not as artificial formations, but as anthropogenically broken natural biocenoses, they also bring a substantial contribution to ecological science. With regards to practical recommendations, they are fully reasonable and have an important national economic value. The monograph of А. М. Sumarokov is a fundamental contribution to ecological science, and its substantive findings can be applied with some nuances in any country of the world, growing the field agricultural crops.

The conducted researches are directed on the solution of one of the most important problems of the space use – a problem connected with existence and inadmissibility of growth the quantity of a technogenic origin space debris on low near-earth and geostationary orbits because its further increase will overlap to mankind an exit in space and will terminate space activity. In the basis of a technique of researches the analysis of an existing ecological condition of the surrounding space environment on which base determined the major factors of pollution of the space and considered ways of struggle against space debris on near-earth orbits is put. It is established that the major factors of pollution of the near-earth space are spent stages of launch vehicles and accelerating units, the space crafts which have terminated its existence, fragments of destroyed artificial space objects, operational elements etc. Space debris basically is concentrated on low orbits and around a geostationary orbit which on the basis of the analysis of statistical data on space crafts starts are in most common use. Here groupings of space crafts of the various particular mission, including space crafts of communication, relay, TV, the early prevention of a rocket attack are concentrated. It is shown that the main ways of struggle against space debris are prevention of occurrence new and removal of the already existing debris. Notable decrease in level of the pollution can achieve at cumulative use of such measures, as an exception of explosions of the space objects, limitation of quantity of the started space crafts, reduction of number of the accompanying fragments injected into orbits at starts. Methods and means of withdrawal from working orbits of space crafts upon termination of term of their active existence and known ways and systems of active removal of already existing fragments of the space debris, such as: application of an ionic bunch, the space ship-towing vehicle, the polyurethane foam, the pulsing laser, harpoon system, electrodynamic cord system are considered. Scientific novelty of the presented results consists in the description of conceptual actions for reduction of pollution of the space. The activities executed in the given direction, have huge practical value as the outer space exploration gives huge advantage and significant progress to mankind, but the further operation at near-earth space by existing methods without acceptance of the measures indicated in the article, its further safe development already will not allow in the near future.
The book, dedicated to the plants of grass and subshrub layer – Kovalenko I. M. Ecology of the lower layer plants of forest ecosystems. – Sumy : University Book, 2015. – 360 p.

Published: February 2018

A large array of information regarding the study of forest vegetation, represented by a great number of scientists, demonstrates the relevance of this direction and at the same time the gaps of existing research on this field. The author of the book is Ihor Mykolayovych Kovalenko, a representative of Sumy ecologists and botanists, a native of the scientific school of the well-known biogeocenologist and ecologist Julian A. Zlobin. The monograph is structured into 8 chapters, conclusions and a list of references. It is worth noting the presence of numerous diagrams, tables and figures which appropriately complement the text material. The peculiarity of the work is that the author, focusing on the lower layer plants of forest ecosystems, has also shown and analyzed the impact of various components of forest ecosystems on each other. This approach is characterized by a complexity which certainly enhances the practical value of the publication and the results it provides. The book is a comprehensive study of the plants of grass and subshrub layer of forest ecosystems. However, the author focuses on the need to conduct the constant monitoring of individual components and ecosystems in general, limited to the nature reserve areas. This publication may be recommended as a methodological manual while conducting such research. Outline of the book sections presented above clearly demonstrates a comprehensive and in-depth study of the lower layer plants of forest ecosystems in the north-east of Ukraine. In general, we believe that the reviewed scientific work of I. M. Kovalenko «Ecology of the lower layer plants of forest ecosystem» is a major contribution to the scientific literature on ecology and sozology. It will undoubtedly find a positive response in the wide circles of ecologists, geobotanists and phytosozologs.

The most characteristic features of the modern civilization stage are runaway growth, integration and further differentiation of knowledges, enhancement of the science role in society. Science is an important factor of global transformation and mankind progress. The existence and prosperity of society depends largely on the success of science which is developed rapidly, justifying correctness, objectivity, reliability, and appropriateness of decisions on long-term planning of economic, environmental, political and social activities. Neither reliable prediction of further long-term effects of our current actions nor correct definition of the immediate tasks of economic activity are possible without a thorough scientific analysis of the numerous challenges that affect the tasks of modern society. Realities of the present state justify absolute needs for multilateral forecasting, modeling of multivariate objective patterns of mankind future, and certainly of science itself and its priorities. Works of scientists that include a monograph of V.I. Shanda, E.O. Yevtushenko, N.V. Voroshilova, Y.V. Malenko offer insights into better understanding and more accurate determination of status, ways and prospects of further science development in general and in level of its individual disciplines. The monograph highlights in retro- and perspective the nature, development, interdisciplinary connections, ontological, gnoseological and theoretical issues, concepts, differentiation of agrophytocenology as a science, represented the systemic vision, elementary and structural analysis of agrophytocenoses, their division and specificity, including chaos and behaviours related to formation of structure, composition and interactions.
LAS ORGANIZACIONES DE BASE DE ALIANZA PAIS: EL PAPEL DE LOS COMITÉS DE LA REVOLUCIÓN CIUDADANA EN LA MOVILIZACIÓN POLÍTICA
Authors: Herrera Llive Klever Vinicio 
Published: February 2018

El presente trabajo describe la conformación y funcionamiento de los comités de la revolución ciudadana, con el objetivo de entender las redes clientelares que sostienen al gobierno de Alianza PAIS. El pedido para constituirlos en cada hogar, en cada cuadra, en cada comunidad, lo hizo Rafael Correa al iniciar su segundo mandato y fue presentado como parte de una estrategia de radicalización revolucionaria gubernamental.La investigación es de tipo descriptivo, con diseño no experimental, documental, empleando fuentes de información primaria y secundaria. Los resultados revelan que las experiencias reales sobre su construcción son insignificantes, que se falsearon las estadísticas sobre su crecimiento y que se debieron recurrir a caciques y punteros locales para cumplir con la demanda presidencial.
LOS ORÍGENES DEL DISCURSO DE APROPIACIÓN SOCIAL DE LA CIENCIA Y LA TECNOLOGÍA EN COLOMBIA
Authors: Escobar Ortiz Jorge Manuel 
Published: February 2018

Mi propósito en este artículo es indagar sobre los orígenes neoliberales del discurso de apropiación social de la ciencia y la tecnología en Colombia. En particular, intento mostrar que los valores o las actitudes promovidos hacia la ciencia y la tecnología mediante dicho discurso, se han asociado directamente con el logro de las metas de producción y desarrollo económico impulsadas por el nuevo modelo de apertura económica que inicia en los años ochenta y se consolida en la década de los noventa con el gobierno Gaviria. Para esto, empiezo con una breve mirada al concepto de política científica, para dar un contexto general. Luego paso a describir lo que podría denominarse la versión oficial (o semioficial) del origen del término en la política científica colombiana, antes de ofrecer una versión más compleja, pero mucho más informativa, de ese origen. Finalizo con algunos comentarios sobre el destino de este término en la política científica colombiana posterior.

AbstractLessons LearnedThe lack of efficacy associated with anti-EGFL7 combined with standard bevacizumab and chemotherapy in this phase II trial in non-small cell lung carcinoma is consistent with the lack of benefit observed in colorectal carcinoma, highlighting the challenge of enhancing the efficacy of VEGF inhibition in unselected populations. Future efforts with agents like anti-EGFL7 should be guided by advances in pharmacodynamic and predictive biomarker development for antiangiogenic agents.BackgroundEpidermal growth factor-like domain 7 (EGFL7) is an extracellular matrix-associated protein that is upregulated during angiogenesis and supports endothelial cell survival. This phase II trial evaluated the efficacy of the anti-EGFL7 antibody, parsatuzumab, in combination with bevacizumab plus platinum-based therapy for advanced or recurrent nonsquamous non-small cell lung cancer (NS-NSCLC).MethodsPatients (n = 104) were randomized to either placebo or parsatuzumab (600 mg) in combination with bevacizumab (15 mg/kg) and carboplatin/paclitaxel, administered on day 1 of each 21-day cycle. Carboplatin and paclitaxel were administered for up to six cycles. Bevacizumab and parsatuzumab/placebo were administered for a maximum of 24 months.ResultsThe progression-free survival (PFS) hazard ratio (HR) was 1.7 (95% confidence interval [CI], 1.0–2.8; p = .047). The median PFS was 6.7 months for the parsatuzumab arm versus 8.1 months for the placebo arm. The hazard ratio for overall survival (OS) was 1.1 (95% CI, 0.5–2.2; p = .847). The objective response rate (ORR) was 29% in the parsatuzumab arm and 56% in the placebo arm. Overall safety and tolerability were consistent with the established toxicity profile of bevacizumab.ConclusionThere was no evidence of efficacy for the addition of parsatuzumab to the combination of bevacizumab and chemotherapy for first-line NS-NSCLC.
Jenseits von Ostmitteleuropa? Zur Aporie einer deutschen Nischenforschung

Ostmitteleuropaforschung - Beyond East Central Europe? The Aporiae of a Niche Research Interest in Germany The article discusses some crucial problems of area studies drawing on the example of East Central European studies in Germany today. Against the backdrop of persistent methodological imperatives stemming from the 19th and early 20th century, we argue that general definitions of space, time or structure are of little use even in relation to a constructed region. Instead, we call for a praxeological approach that takes into consideration specific situational entanglements and their actors. In the context of global, European, imperial or transnational turns in historical cultural studies, a non-hierarchical, spatial and temporal perspective becomes essential. This article seeks to encourage discussion about the chances and risks that current developments in historical area studies in Germany entail, while also providing an impulse to think about possible future ramifications.
