Authors: Esqueda-Elizondo José Jaime , Trujillo-Toledo Diego Armando , Pinto-Ramos Marco Antonio , Reyes-Martínez Roberto Alejandro
Published: April 2021

A methodology for the selection and determination of electroencephalographic (EEG) signal patterns is presented at the case study level, which can later be used as on-off control signals in other applications. Electroencephalographic signals are acquired through the use of a brain-computer interface (BCI). These systems capture electrical signals from the cortex of the brain and transfer them to a computer so that they can be analyzed by algorithms and some action is taken. In this case, the EEG signals are acquired through the wireless 14-channel Epoc+ platform. The methodology used consists first in acquiring signals from the user sample in three scenarios: in relaxation, thinking about turning on and off. Subsequently, the wavelet transform of each of the channels is obtained for each of the cases and the most significant coefficients are taken into account. Then, through digital signal processing algorithms, descriptive parameters are obtained for the on and off cases, which are used as patterns to describe each of the actions. With this information, a comparison between the incoming signals and the previously stored patterns is made to execute one of the established commands.

Authors: Kopylova Galina , Lyubushin Aleksey , Taranova Larisa
Published: April 2021

A new technology for predicting strong earthquakes with a magnitude range of Mw about 7 and more is considered, based on the use of continuous recordings of seismic noise on a network of 21 broadband stations of the GS RAS in the region of the Kamchatka Peninsula, the Commander Islands and the Paramushir Island. The article is described a forecasting algorithm created by A.A. Lyubushin, IPE RAS, and the state of its implementation in the Kamchatka Division GS RAS for the purpose of an advance (months - first years) assessment of the strong earthquakes preparation sites. The data processing algorithm includes the calculation of four noise statistics time series for each station and the construction of their spatial distribution maps for different time intervals. We used four noise statistics, including the minimal entropy of the orthogonal wavelet coefficients squares and three characteristics of the multifractal spectrum of singularity – the generalized Hurst exponent, the carrier width, and the spectral wavelet exponent. Based on previous research, characteristic features of the four seismic noise statistics behavior at preparation stages of the local earthquakes 2013-2016 with Мw=6.6-8.3 were revealed, corresponding to similar changes before the two earthquakes with Мw=8.3 and 9.0 in Japan. It was found that an increase in the danger of a strong earthquake is accompanied by an increase in minimal entropy and a decrease in the carrier width and other parameters of the singularity spectrum. Since 2020, the processing of current data from the network of broadband stations of the GS RAS in the Far East region has been carried out in accordance with the seismic forecasting algorithm for drawing up quarterly forecast conclusions, which are sent to the Russian Expert Council on Earthquake Forecasting, Seismic Hazard and Risk Assessment (REC) and to Kamchatka Branch of REC

Published: April 2021

The aim of the study was to evaluate the histopathological changes in the lungs of patients who died of a new coronavirus infection (COVID-19) in relation to the length of hospital stay. We evaluated lung autopsy material, autopsy reports, and death summaries of 39 patients who died of COVID-19. The length of hospital stay ranged from a few hours to 25 days. At all stages of the disease, lung alterations (desquamation of bronchial and alveolar epithelium), circulatory disorders (alveolar edema and hemorrhages, congestion in small blood vessels, thrombosis), compensatory response (fibrosis) were identified. The patients who died during the first week of hospitalization demonstrated predominant signs of circulatory disorders (alveolar edema, hyaline membranes, alveolar hemorrhages, congestion in small blood vessels). Fibrosis, usually not typical for the first week of acute respiratory distress syndrome, was detected in 46% of the deceased during the first week of hospitalization, which may be due to late hospitalization or patterns of fibrosis development in COVID-19. For those who died in the 2nd and 3rd weeks of hospitalization, the compensatory response and progression of fibrosis were noted. By the 3rd week, pulmonary fibrosis was detected in 91% of patients. Thrombotic complications (thrombosis, pulmonary artery thromboembolism) were observed in almost half of fatalities occurring during weeks 2–3. Hemorrhagic infarction was found in 43% (6 patients) who died during week 2 of hospitalization, three of them were diagnosed with pulmonary embolism, indicating progression of pulmonary vascular damage.

Single-stranded DNA-binding (SSB) proteins play an important role in DNA metabolism involving DNA replication, recombination, and repair in all living beings. In molecular biology, SSB proteins are used as enhancers to increase the efficiency and specificity of PCR. Thermostable SSB protein eliminates secondary structure or dimer formation and significantly increase the effectiveness of amplification of DNA fragments. In this study, it was ensured that the SSB gene of thermophilic bacteria Thermus aquaticus (T. aquaticus) was cloned into the pET28b vector and expressed in E. coli BL21 (DE3) PLysE cells. Then, the purification of the SSB protein produced in E. coli BL21 (DE3) PLysE cells was performed. 20 mg SSB protein was obtained from 1L bacterial culture, and its purity was more than 90%. It was shown by the PCR experiment that the SSB protein produced in this study could increase the amplification efficiency.

Published: April 2021

Adjusting the dose of radiation which is received by a cancer patient during radiotherapy is very important. The use of dosimetric gels to calculate the applied dose distribution three- dimensionally is a current research topic in radiotherapy. In this study, 16 different Fricke gels including gluconic acid (GA) were produced. These gels were irradiated from 0 to 250 cGy with increments of 50 cGy. MR intensity values and images, UV absorbance values and FT-IR spectra of gels were obtained before and after the irradiation process. The UV absorbance and MR intensity values showed a linear increase in relation to the increase in the applied dose and the amount of ferrous sulfate and GA content in the gels. The oxidation of iron increases as a result of the interaction with hydrogen peroxide which is the product of the irradiation process and GA, and thus the response of the gel to the irradiation process becomes more effective.

Authors: YAVUZ Mehmet Nedim , ÖZTÜRK Zübeyde
Published: April 2021

Increasing the speed of transportation has been a subject that human beings have been working on for many years. Because of insufficient traffic corridors, the interest of more passenger in limited time and the advancement of railway technology, the high-speed ground transportation systems have developed. Nowadays, these time-saving transportation systems are becoming important increasingly and systems that will ensure these are implemented and new ones are being researched. High speed ground transportation systems can be divided into three categories: Conventional high-speed railway, Maglev and Hyperloop transportation system. Within the scope of this study, it is aimed to investigate the advantages and disadvantages aspects of high speed transportation systems by comparing in terms of speed, capacity, energy consumption, cost and environmental effects. Conventional high-speed railways can provide high capacity, comfort and safety and reliability thanks to enormous operational experience as regards other systems. The Maglev technology can offer more remarkable travel times, energy efficient and better operational performance. However, high investment cost and incompatibility with other modes are seen the disadvantage features of this technology. The Hyperloop technology is a considerable innovative transportation system which is popularized with publishing design document by Elon Musk in 2013. Projected high-speed and appealing travel times can be evaluated as the advantages of the Hyperloop transportation system. However, there are safety, reliability, comfort and engineering design challenges to overcome in this technology. Taking everything into consideration, the Hyperloop transportation system has potential to be an alternative mode to other systems.

Socialization and legal counseling on the Tuha Peut Traditional Institution in dispute resolution in Sawang District are part of community service activities. The background of this activity is that in the Qanun of Customary Institutions, Tuha Peut is one of the customary institutions that has the authority to settle disputes between members of a community of a village. In Sawang Subdistrict, Aceh Utara District, there are still many customary disputes that have not been resolved by customary settlement in the village and many have been reported by the community to the police. This is also due to the lack of knowledge of the Tuha Peut Customary Institution in resolving disputes at the village level. This socialization and legal counseling was carried out by presenting the material and continued with a discussion of questions and answers and swearing back. The results of socialization and legal counseling in Sawang District found that the results of the feedback provided by participants experienced an increase in understanding of the role of the Tuha Peut Traditional Institution in dispute resolution. The implementation of this activity received a good response from the Tuha Peut Customary Institution, because they increased their knowledge and they rarely got activities like this.
Graphical method for determining of limit and permissible values of drawing and friction coefficients, stress, drawing angle and delta-criterion for shape of plastic deformation zone
Authors: Gur’yanov G.N.
Published: April 2021

The maximum and permissible values of the coefficients of drawing and friction, the Delta criterion of the shape of the deformation center, the index of the deformed state, the angle and drawing stress are determined graphically for different models of hardening and values of the anti-tension stress. For the determination, cartesian graphs were used, on the ordinate axis of which the desired indicators are located, and on the abscissa axis the values of the I.L. Per lin safety factor obtained by varying the extraction coefficient. The permissible values of the drawing coefficient and drawing stress decrease with the growth of the safety factor of I.L. Perlin. The dependence of the limit and permissible values of the Delta criterion for the optimal value of the drawing angle on the deformation parameters and the harden ing model is shown. The maximum and permissible values of the coefficient of friction are higher at the optimal value of the drawing angle. For the first time, the possibility of increasing the limit value of the coefficient of friction from the action of anti-gravity is established. The limit and permissible values of the coefficient of friction decrease with the increase in the value of the coefficient of drawing and increase with the increase in the coefficient of hardening k. Curves for the dependences of the safety factor, the stress state indicator and the absolute safety margin Zap on the value of the drawing angle fix small and large values of the limit drawing angle on the abscissa axis. Small limit values of the drawing angle do not differ significantly in value for different values of the drawing and hardening coefficients, in contrast to large limit values of the angle. The action of counter-gravity increases the small limit angles and decreases the large limit angles. Determination of the limit and permissible values of the coefficients of drawing and friction, the Delta criterion, stress and drawing angle contributes to the rational choice of modes of deformation of the wire (bar).

Most of the onomastic units mentioned in the written monuments of ancient times are valuable sources in terms of studying the past, language, lifestyle, ethnogenesis, ethnography of our people today. While these monuments are important in terms of clarifying historical realities and shedding light on obscure issues, on the other hand, their study is politically important in modern times. At a time when our hated neighbors are looking at our lands and making historical distortions, the study of onomastic units in ancient monuments – toponyms, anthroponyms, oronyms, hydronyms, etc. – can be a convincing answer to baseless fabrications. It should be noted that we come across information and explanations about each of these hydronyms in scientific and historical sources written from ancient times to the present day, and the core of each of them is of Azerbaijani-Turkish origin. The monument involved in the study names countless water bodies associated with the territory of Azerbaijan. They are also very valuable in terms of studying the lexical and semantic development of our language. We come across information and explanations about each of these hydronyms in scientific and historical sources written from ancient times to the present day. One of the hydronyms directly connected with the territory of Azerbaijan in the source is the Caspian Sea. Books and articles about the Caspian Sea give it different names and etymological-linguistic analysis of the word Caspian. Another hydronym mentioned in the source is Tartar river. The article provides extensive information about the Tartar River in terms of its geographical structure. The hydronym Tartar is given in Arabic, Russian, Georgian and ancient Turkic sources with different phonetic structure. The name of the Urdun River is mentioned several times in the source. However, it should be noted that the Urdun River flows not in the Albanian country, but in the Middle East, and most of it flows in the territory of modern Jordan. Although the explanation of some of the hydronyms included in the ancient Caucasian Albanian territory in the source is convincing, the exact explanation of many ancient hydronyms still remains controversial. One example of such controversial hydronyms is the Urdun River. The last hydronym mentioned in the article is Goycha river. Extensive geographical, historical, etymological interpretations and linguistic analysis of the hydronym are given. Key words: river, morphemes, geographical names, modern areal, hydronyms, onomastic

Published: April 2021

The English playwright Harold Pinter's plays "The Guardian" and "The Dwarfs" chosen from his drama are addressed to. The "chaotic world" observed in the plot of the plays is analyzed and the conclusion that the heroes are born of conflict in their relationships is defended. The object of research is to take into account the difference between the consciousness and reality.

Rice Husk Ash (RHA) is one of the agricultural waste byproducts available widely in the world and contains a large amount of silica. In Bangladesh, stones cannot be used as coarse aggregate in infrastructure works as they are not available and need to be imported from abroad. As a result, bricks are mostly used as coarse aggregates in concrete as they are cheaper and easily produced here. Clay is the raw material for producing brick. Due to rapid urban growth and the industrial revolution, demand for brick is increasing, which led to a decrease in the topsoil. This study aims to produce lightweight block aggregates with sufficient strength utilizing RHA at low cost and use them as an ingredient of concrete. RHA, because of its pozzolanic behavior, can be utilized to produce better quality block aggregates at lower cost, replacing clay content in the bricks. The whole study can be divided into three parts. In the first part, characterization tests on RHA and clay were performed to determine their properties. Six different types of RHA from different mills were characterized by XRD and SEM analysis. Their fineness was determined by conducting a fineness test. The result of XRD confirmed the amorphous state of RHA. The characterization test for clay identifies the sample as “silty clay” with a specific gravity of 2.59 and 14% optimum moisture content. In the second part, blocks were produced with six different types of RHA with different combinations by volume with clay. Then mixtures were manually compacted in molds before subjecting them to oven drying at 120 °C for 7 days. After that, dried blocks were placed in a furnace at 1200 °C to produce ultimate blocks. Loss on ignition test, apparent density test, crushing strength test, efflorescence test, and absorption test were conducted on the blocks to compare their performance with the bricks. For 40% of RHA, the crushing strength result was found 60 MPa, where crushing strength for brick was observed 48.1 MPa. In the third part, the crushed blocks were used as coarse aggregate in concrete cylinders and compared them with brick concrete cylinders. Specimens were cured for 7 days and 28 days. The highest compressive strength of block cylinders for 7 days curing was calculated as 26.1 MPa, whereas, for 28 days curing, it was found 34 MPa. On the other hand, for brick cylinders, the value of compressing strength of 7 days and 28 days curing was observed as 20 MPa and 30 MPa, respectively. These research findings can help with the increasing demand for topsoil of the earth, and also turn a waste product into a valuable one.

Pobreza en hogares con jefatura femenina en Argentina. Una comparación entre el norte grande y el resto del país
Authors: Paz Jorge , Arévalo Carla
Published: April 2021

La pobreza en hogares con jefatura femenina ha sido objeto de numerosos estudios en varios países del mundo, pero no en la Argentina. En este trabajo abordamos ese tema y exploramos la situación del Norte Grande de Argentina (NGA). Esta región tiene los niveles de pobreza más elevados del país, tanto a juzgar por la dimensión monetaria como no monetaria (González, 2019), y niveles comparativamente altos también de personas viviendo en hogares monoparentales y extensos, en los que los riesgos de pobreza son mayores que en el resto de hogares. La pregunta que intentamos responder son dos: a) si existe evidencia de feminización de pobreza en el país, y b) si el NGA registra un nivel de feminización de pobreza mayor que la media nacional, luego de controlados los factores que determinan la pobreza de los hogares. Encontramos que la Argentina experimenta el fenómeno de feminización de pobreza, que la feminización de la pobreza aumentó en los últimos siete años (desde 2013) y que la región del NGA no presenta niveles de feminización de pobreza mayores al resto del país una vez controlados los factores determinantes de la pobreza.
Los nuevos paradigmas económicos y tecnológicos en la actividad turística y su relación con el ambiente
Authors: Dieckow Liliana María
Published: April 2021

Este artículo presenta resultados de la tarea docente - investigativa sobre el nuevo paradigma económico y las nuevas formas de comunicar, comercializar, vender y consumir en turismo. Este nuevo paradigma económico relacionado con la tercer o -según autores- la cuarta revolución industrial que considera al pro - común colaborativo, la reducción de los costos marginales cercano a cero, las nuevas energías sustentables y el internet de las cosas. A ello se le suman las nuevas Generaciones de personas, los Millennials y los Centennials con motivaciones, emociones y comportamientos particulares para sus experiencias de viajes, muy conectados a redes sociales y a las tecnologías, que llevan a reconfigurar la actividad económica del turismo desde sus bases. Incluso se habla del surgimiento de nuevos verbos asociados al uso de la tecnología por parte de estas generaciones. Nuevas plataformas de búsqueda y portales de compras como Booking, y agencias online como Despegar, que se imponen en el mercado. Ante estos cambios de escenario y de demanda, las empresas deben adaptarse a esta nueva economía y bases tecnológicas, redefiniendo su forma de conectarse con sus potenciales clientes y su forma de desarrollar la actividad turística de forma más sustentable, más activa y menos masiva.
An Analysis of the Migration of Turks of Bulgaria to Turkey in 1950-51 with the Turkey’s Domestic and Foreign Policy of the Era
Authors: Karapınar Ahmet Can
Published: April 2021

Movement of populations has been one of the main drivers of the history of humanity. For a geography which is at the crossroads of different cultures and civilizations such as Anatolia, this is much more relevant. Among the mass movement of migrations in Turkish history; migrations from Bulgaria, with their number of migrants and the time span, have a special place. Specifically; 1950-51 Migration, by giving us a chance to study political history of the early years of the Cold War at that geography, offers us a quite interesting study area.
In this article, migration of Turks of Bulgaria to Turkey in 1950-51 would be analyzed with a special attention to the Turkey’s domestic and foreign policy of the era. In order to have a holistic understanding, first the background would be explained by studying on the situations of the respective countries during and in the aftermath of World War II. While looking to the aftermath of World War II, the process which led to the 1950-51 Migration would be studied in detail. Later, 1950-51 Migration would be studied with its implications on Turkish domestic and foreign policy. Connected to that, foreign aid issue too would be studied. Finally the conclusion would be made. The analysis shows that, 1950-51 Migration was a milestone event in the history of the Republic of Turkey which shaped Turkish domestic and foreign policy in the early years of the Cold War.
