Published: July 2019

Russia’s entry into the top five economies of the world depends, among other things, on the development of the financial sector, being a necessary condition for the economic growth of a developed macroeconomic and macro-financial system. The financial sector represents a system of relationships for the effective collection and distribution of economic resources, their deployment according to public demand, reducing the risk of overproduction and overheating of the economy.Therefore,the subject of the researchis the financial sector of the Russian economy.The purpose of the researchwas to formulate an approach to alleviating the risks of increasing financial costs in the real sector of the economy by reducing the impact of endogenous risks expressed as financial asset “bubbles” using the experience of developed countries in the monetary policy.The paper analyzes a macroeconomic model applied to the financial sector. It is established that the economic growth is determined by the growth and, more important, the qualitative development of the financial sector, which leads to two phenomena: overproduction in the real sector and an increase in asset prices in the financial sector, with a debt load in both the real and financial sectors. This results in decreasing the interest rate of the mega-regulator to near-zero values. In this case, since the mechanisms of the conventional monetary policy do not work, the unconventional monetary policy is used when the mega-regulator buys out derivative financial instruments from systemically important institutions. As a conclusion, given deflationally low rates, it is proposed that the megaregulator should issue its own derivative financial instruments and place them in the financial market.

O conhecimento da distribuição espacial da população urbana possui importância em várias áreas das ciências sociais. No Brasil, os mapas de densidade demográfica são normalmente construídos utilizando somente os dados do censo demográfico. O problema desta abordagem é que muitas vezes, os limites dos polígonos censitários não se restringem as áreas habitadas, incluindo também praças, cemitérios e indústrias. Para melhorar o mapeamento, dados auxiliares podem ser incorporados para refinar o cálculo da densidade (chamado de dasimetria). Neste trabalho, o método dasimétrico foi adotado para o município de Vespasiano, Minas Gerais, Brasil. A densidade foi calculada utilizando como dado auxiliar o mapa de uso da terra gerado a partir das imagens do Google Earth. As áreas residenciais foram combinadas com os dados do censo utilizando o Sistema de Informação Geográfica ILWIS. Os resultados revelaram que o método dasimétrico é uma alternativa viável para melhorar a visualização da distribuição espacial da população. AbstractUnderstanding the spatial distribution of urban population is crucial for a wide range of applications in social sciences. In Brazil, demographic density maps are usually set using only information acquired from the census datasets. Theproblem of adopting this approach lies on the fact that the unit the census boundaries often do not comprehend habited areas only, including also square, commercial, and industrial areas. Improvements in cartographic representation is possible using the dasymetric method, an approach that consists of refining the spatial structures of the census polygonsby using ancillary data. The dasymetric method was employed to refine the demographic density map of Vespasiano County, Minas Gerais. It was used the ILWIS Geographic Information System (GIS) for integrating the census datasets and the land use map. The result acquired in this research showed that the procedure adopted is a feasible alternative that may be used for improving the spatial distribution of population.

This experiment aimed to evaluate the toxic influence of ochratoxin- A (OTA) feed contamination and the effectiveness of some feed-additives (Humic acids, Bio-Plus 2B, Bio-Mos) in detoxifying ochratoxicosis. Thirty five day old weaned Animal Production Research Institute (APRI) rabbits were selected and were allocated to four groups. Group 1 (control, OTA group): rabbits were fed basal diet (ochratoxin- A level: 19 μg /kg diet). Group 2: rabbits were fed a basal diet containing 0.2 % humic acid. Group 3: rabbits were fed a basal diet containing 0.4 mg/kg diet Bacillus subtilis and Bacillus licheniformis (Bio-Plus 2B). Group 4: rabbits were fed a basal diet containing 0.1% Manna oligosaccharides (Bio-Mos). The control group showed significantly reduced feed intake, daily weight gain and growth performance index. Furthermore, there was a significant increase in AST, ALT, malondialdehyde, creatinine, and urea. Moreover, Bio-Mos group revealed significantly increased serum Hemoglobin, PCV, RBCs, MCV and RBCs/ lymphocyte ratio, and significantly decreased serum SOD and CAT activities. Additionally, internal organs (liver, kidney and intestine) of groups received feed additives revealed less deteriorative change in histopathological investigations in comparison with the control group. In conclusion, supplementation of contaminated feed with ochratoxin-A by feed-additives improves feed intake and final body weight and reduces mortality rate of rabbits. In addition, it improves liver and kidney functions and reduces its pathological changes, and restores antioxidant to its normal level.Key words: rabbits; ochratoxin-A; growth performance; anti-oxidant

Published: July 2019

AbstractThis study focuses on the use of lightweight design and optimization methodology as a computer aided approach to enhancing the conceptual design of an impact attenuator for a Formula SAE race car. The most important question answered here is how to improve conceptual design outlines to assist a designer with respect to an impact attenuator design. In this study, different tools for lightweight design and optimization are compared to find the most suitable procedures and optimization techniques for an impact attenuator design. The geometrical features used as design variables and constraints are defined according to Formula SAE rules. The optimization problem is solved using a genetic algorithm and sequential quadratic programming methods by means of meta-modeling techniques. It is found that lightweight design and optimization can be used to enhance the conceptual design outlines of an impact attenuator through EPP foam, kriging meta-modeling and genetic algorithm optimization techniques.
Friction stir welded and deep drawn multi-material tailor welded blanks

AbstractThe ever increasing demand for more resource-efficient and safer vehicles in today's automotive industry makes lightweight construction techniques necessary. However, overcoming contradicting requirements arising from lightweight design and safety remains a challenging task. The extent to which lightweight measures can be applied in order to save fuel, heavily depends on the fact that rising safety requirements have to be met by increasing strength of parts. This contradicting demand for parts with high strength and low weight leads to the development of new production technologies. One example, regarding car body components, is the tailor welded blank (TWB) technology. In tailor welded blanks, materials and thicknesses are locally adapted to meet the needed strength and strain properties while keeping the weight as low as possible. While tailor welded blanks consisting of similar materials with different thicknesses are already used in vehicles, the use of TWBs with dissimilar materials, e.g. steel and aluminum, is still in development due to the problems in joining dissimilar materials. Especially when manufacturing parts made of TWBs through joining and subsequent deep drawing, the joint needs to have very good strength properties in order not to fail during forming. One way to overcome these joining difficulties is friction stir welding. In this paper, a methodology is presented to produce multi-material tailor welded blanks with varying thicknesses through friction stir welding (FSW) and deep drawing in a subsequent step. A newly developed FSW joint configuration is used to weld steel sheets in 1 mm thickness to 2 mm thick aluminum sheets. A welding parameter study is conducted to investigate the influence of the process parameters on the joint quality. Tensile and Nakajima tests show that the joint strength, obtained with optimal process parameters, exceeds the strength of the steel base material. Thus, failure occurs in the steel, whereas the joint remains intact. The friction stir welded blanks were furthermore deep drawn. Two different tool approaches were tested to compensate the different sheet thicknesses during the forming process. Using the more suitable approach, blanks were deep drawn with three different punch geometries to show the potential of friction stir welding for the manufacturing of multi-material tailor welded blanks.
