Authors: DEMİRCİOĞLU Fatih
Published: December 2022

Sovyetler Birliği’nin dağılmasından sonra Orta Asya, Avrasya’da bir uluslararası alt-sistem olarak ortaya çıkmıştır. Orta Asya ile ilgili çalışmaların birçoğu bölgeyi büyük güçler arasındaki politik ve ekonomik mücadelede yalnızca bir paylaşım sahası olarak değerlendirmektedir. Bu durum, bölgenin iç siyasal dinamiklerinin genellikle göz ardı edilmesine sebep olmaktadır. Bu çalışma, İngiliz Okulu perspektifinden Orta Asya analizinin, bölgede var olduğuna inanılan gerçeklikten çok daha fazlasını ortaya koyacağını öne sürmektedir. Zira günümüzde Orta Asya’nın; küresel ve yerel işbirliklerinin, bölgenin kendine özgü dinamiklerini yansıtan kurumlar aracılığıyla belirgin hale geldiği bölgesel bir uluslararası toplumu temsil ettiği genel kabul görmektedir. Bu araştırma, Orta Asya’da uluslararası politikayı İngiliz Okulu bağlamında incelemek için daha tikel ve aktörlerin gözlemlerine dayalı bir okuma önerirken aynı zamanda bu yaklaşımın kapsamını örneklem üzerinde, bölgesel seviyedeki uluslararası toplum üzerine karşılaştırmalı bir gündemi öne çıkararak genişletmeyi hedeflemektedir.

Authors: Avramenko A.A. , Tyriniv A.I. , Dmitrenko N.P. , Kovetska M.M.
Published: December 2022

Boiling is one of the main physical processes, which that take place in heat exchange equipment designed for various purposes. The problem of removing large thermal loads from the heated surface is important for nuclear energy, chemical industry, metallurgy, electronics and other areas where intense heat is released. Boiling processes in process equipment perform important protective functions and can control its effectiveness.

According to the boiling curve, with increasing temperature power, the flow passes through five regions, starting from the single-phase region of free convection and ending with the region of developed film boiling.

The purpose of this article is an analytical study of heat transfer at spontaneous transition to the film boiling (explosive type of boiling), taking into account the unsteady nature of this process.

In order to achieve the aim of this research, two analytical approaches were used, namely, the symmetry method and the Laplace method. As a result of mathematical transformations, expressions for the nonstationary temperature distribution and the Nusselt number are obtained. The obtained expressions make it possible to analyze the dynamics of non-stationary heat exchange processes. The results of analytical and numerical modeling were also compared. It was found that the results of the self-similar solution have a better comparison with numerical data compared to the results according to the Laplace method.

Authors: KAYA Serhat
Published: December 2022

Conehead thyme (Thymbra capitata) is widely distributed in the countries of the Mediterranean region and used due to its medical properties. The antibacterial, antifungal, and strong antioxidant properties of T. capitata are known. The model organism Galleria mellonella is mostly preferred for immunological studies and for the study of human pathogens. The aim of the study was to determine the effect of the ethanolic extract of T. capitata on the antioxidant defense of the hemolymph in G. mellonella larva. Solutions prepared with Phosphate-Buffered Saline (PBS) from the dry matter obtained from ethanolic extract at doses between 2 mg mL-1 and 20 mg mL-1 were injected into G. mellonella larvae. According to our findings, T. capitata extract had no effect on malondialdehyde (MDA) levels. However, it was determined that all doses between 10 to 20 mg mL-1 significantly reduced superoxide dismutase (SOD) and catalase (CAT) activities compared to the control groups. According to the results of our study, high doses of T. capitata extract had negative effects on G. mellonella antioxidant defense.

Published: December 2022

Resumo: Este artigo versa sobre a problemática que permeia as contradições do modelo de desenvolvimento econômico, acelerado pelo processo de expansão do agronegócio nas áreas do Cerrado. Desse modo, as demandas do consumo interno e principalmente externo, reforçam o aumento do desmatamento da vegetação nativa e mudanças significativas na relação homem natureza, pois, as condições impostas pelo capital financeiro no setor das commodities agrícolas, também são responsáveis pela intensificação dos impactos socioambientais – alterando a vida das comunidades tradicionais, bem como estimulando os conflitos e violência no campo. As transformações socioespaciais impulsionadas pelo agronegócio estão alterando drasticamente a paisagem natural, ou seja, dando lugar às monoculturas destinadas ao abastecimento do mercado externo. A ausência de um manejo sustentável vem ocasionado sérios problemas e consequências para o meio ambiente e a sociedade. Sendo assim, esse modelo de desenvolvimento, é gerador de divisas econômicas, mas apresenta um custo elevado de degradação dos bens naturais. Portanto, refletir esse modelo é necessário para entender a sua lógica que prioriza somente o viés econômico, sustentado na acumulação do lucro e na concentração da riqueza.Palavras-chave: Cerrado; Agronegócio, Desenvolvimento econômico; Bioma.
Use of augmented reality for remote control of mobile robots in the presence of time delays in data transmission channels
Authors: Popov Dmitrii
Published: December 2022

The paper is devoted to the teleoperation of ground mobile robots in extreme conditions. The presence of time delays in information transmission channels has a significant impact on the efficiency of control. The total delay values can range from hundreds of milliseconds to units of seconds. Sufficiently large values are the reasons for the loss of stability of control systems. To reduce the negative impact of delays, it is proposed to use a method of supporting the operator, which consists in superimposing information about the robot's position on the image received from the video camera and displayed on the control panel at the moment when it receives the generated commands. The position calculation uses the fact that telemetry and command transmission delays are generally much less than video transmission delays. The proposed method is simple, requires a minimum amount of computing resources and can be implemented as a part of low-cost robotic systems. The presented simulation results demonstrate the effectiveness of the method.

Published: December 2022

Introduction to the topic under investigation. With the transition to the information economy, intellectual capital is becoming increasingly important and can be considered as a source of formation of the competitiveness of an enterprise. It should also be noted that despite the many approaches to assessing competitiveness, not all of them withstand criticism or are widely used in practice. Purpose. The purpose of the study is to analyze the intellectual capital and competitiveness of industrial enterprises of the Baltic states. Methodology. The study uses quantitative and qualitative methods; the value added intellectual coefficient (VAIC) was used to assess intellectual capital, while the dynamic method and rating assessment of financial indicators were used to assess the competitiveness of enterprises. Main results. The paper analyses the competitiveness of enterprises and calculates the value added intellectual coefficient (VAIC) of industrial enterprises whose shares are listed on the Nasdaq Baltic market. The study confirms that more efficient use of intellectual capital provides higher indicators of competitiveness of an enterprise; however, the competitiveness of an enterprise is influenced by other factors, for example, the sources of financing used. The theoretical contribution. The dynamic method of assessing the competitiveness of enterprises was employed; it was shown that more effective use of intellectual capital provides an enterprise with competitive advantages. Practical implications. To assess the competitiveness of an enterprise, we use a refined dynamic method, which is supplemented by the VAIC indicator, which will allow us to take into account in the assessment the effectiveness of the use of the intellectual capital of an enterprise. Keywords: intellectual capital, competitiveness, value added intellectual coefficient (VAIC), dynamic method of competitiveness, rating assessment of financial indicators.
