Published: April 2021

In this study, we propose an approach using the gamma transmission technique based on the combination of the experimental and simulated data for determining the percentage concentration of the acid solution. The experiment consists of a collimated 137Cs radioactive source emitting a narrow gamma beam of 662 keV and a NaI(Tl) detector. Monte Carlo simulation data is used to construct the calibration curve of lnR versus the percentage concentration of acid solution at different temperatures (R is the ratio of the area under a transmission peak for an acid solution relative to that for water). The percentage concentration of the acid solution is determined based on the calibration curve and the experimental ratio R. The obtained results showed that this approach was feasible in which the percent concentration of 7 in total 8 samples of the sulfuric acid solution are less than 5% in comparison with one of the reference samples. There is only one sample with a relative deviation of 7.6%. These preliminary results suggest that it is possible to develop nondestructive testing for the rapid determination of the percentage concentration of acid solutions based on the gamma transmission technique.

Published: April 2021

Curcuma zedoaria (Berg.), belongs to the Zingiberaceae family, is one of the medicinal plants that is found in Southeast Asia. This plant is known as “Nghe tim” in Vietnam; and a decoction of its rhizomes has been used traditionally for the cure flatulence, fatigue, and hepatitis. Previously, some studies on the chemical constituent of the rhizomes of C. zedoaria have reported plenty of curcuminoids and sesquiterpenoids together with their derivatives, which have shown a lot of various bioactivities such as antiproliferative characteristic, anti-ulcer, antioxidant and antibacterial potential. By chromatography column method along with preparative thin layer chromatography on a normal phase silica gel on the EtOAc extract of the rhizomes of Curcuma zedoaria, we have isolated five pure compounds. Their chemical structures have been elucidated by NMR techniques and comparison with publishing data that have determined to be gajustulactone A (1), isozedoarondiol (2), neolitacumone (3), β-sitosterol (4), and β-stigmasterol (5). The results of this study have contributed to the scientific data system on the chemical composition of Vietnamese medicinal plants, especially the rhizomes of Curcuma zedoaria grown in Tinh Bien, An Giang. Therefore, there is more evidence to continue screening studies to detect interesting biological activities from this species.

Published: April 2021

As analyzing geomagnetic data at low latitude areas for instance the Mekong Delta (latitudes 11,07o), significant problem is that both of the magnetization and ambient field are not vertical totally, making magnetic anomalies antisymmetrical and often skewed to the location of the sources. In this paper, two-dimensional continuous wavelet transform (2-D CWT), using Farshad-Sailhac complex wavelet function is studied and applied for reducing the magnetic anomaly to a symmetrical one - this located on the source of the anomaly, and then determining the position of the center of the object causing anomalies by wavelet transform modulus maxima (WTMM) method. Next, magnetic data is extracted in two perpendicular directions passing through the center of the source to perform one-dimensional continuous wavelet transform (1-D CWT) to estimate the shape, depth and size of the source. Then, using the Marquardt algorithm to solve the inverse problem by least-squares method to further identify other characteristic parameters of the source such as: vertical size, remanent magnetization vector. The reliability of the proposed method is verified through theoretical models before application for analyzing the geomagnetic data in the Mekong Delta. The results are consistency with deep hole data, having small root mean square error, contribute to a better interpretation of the geological nature of the magnetic anomaly sources in the study area.

Published: April 2021

This study investigated the effect of changing the density of Ag nanoparticles on the ZnO/Ag nanorod structure on the SERS substrate signal amplification ability. First, ZnO nanorods were fabricated by the sol - gel method combining with the chemical bath deposition method. Next, the Ag nanoparticles were decorated on ZnO nanorods by the DC magnetron sputtering method. The density and size of the modified Ag nanoparticles on the ZnO nanorods were changed by adjusting the sputtering times to 5, 10, 15 and 20s respectively. The optical properties of the material are characterized by UV - Vis and PL measurements. The surface morphology of ZnO nanorods and Ag nanoparticles were investigated by scanning electron microscope (SEM). X-ray diffraction measurement (XRD) is used to examine the crystal structures of materials. The composition and distribution of the chemical elements inside the material were investigated by Energy-dispersive X-ray spectroscopy (EDX). The ability of SERS substrates to amplify Raman signals was evaluated by measuring the R6G solution and investigating application for abamectin with a laser excitation wavelength of 532 nm. The results showed that SERS ZnO/Ag substrates with sputtering time of 15s gave the best ability to amplify SERS with the detection of R6G solution at 10􀀀9 M and abamectin at 50 ppm.

Climate change is promoting researches on materials which is capable of converting environmentally friendly energy, in which materials that convert heat into electricity are receiving significant attention, because their ability of converting heat to electricity not only generates the electricity but also contributes to slow down the consumption of fossil fuel. The existence of point defects in the semiconductors greatly effected properties of materials, especially thermoelectric properties. Therefore, the study of defects in materials is a popular research trend today. In this study, we focus on evaluating the existence of oxygen interstitial in CuCr1􀀀xMgxO2 [0.00 x 0.30] compounds, because oxygen interstitial greatly affected the thermoelectric properties of this material. Based on X-ray photoelectron spectroscopy (XPS) analysis, at the large ratio of Mg impurity x = 0.15, the compound had the highest percentage of oxygen interstitial and was also a good thermoelectric material. In addition, it could be also seen that CuCrO2 material being doped a large Mg doping ratio (x = 0.15) was suitable for thermal-to-electrical applications rather than the ones with a small ratio (x 0.05).

Published: April 2021

Democratic transition processes manifested in the Latin American region since the mid-1980s. – the period of the beginning of the “fall” of military dictatorships and the return to civilian control. These processes were directed and organized by left-wing forces, which not only participated in struggle against dictatorships, but also took part in the restoration of key political institutions - elections, courts, and the adoption of new constitutions. This article, based on archival materials, media materials, memoirs, determines the features of the participation of Latin American left forces in the democratic transition, their place in the formed political structures in the context of the legacy of the Comintern and new opportunities.
Colombia of the 20th century: the history of the country in the history of cinema
Authors:   Institute of World History of the Russian Academy of Sciences, Ekaterina Grantseva
Published: April 2021

Colombian cinema, the peculiarities of its development and problems, cannot be separated from the tragic and painful pages of the history of Colombia in the 20th century. In the panorama of the national cinematography’s of Latin America, the cinema of Colombia has long been on the side lines, significantly yielding to Argentina and Mexico, and also constantly experiencing pressure on the film market from Hollywood. Unlike Colombian literature, which conquered the world with "magical realism", the cinema of this country gravitates towards social realism. He is characterized by a bold approach to the most difficult and painful topics, a constant interest in the realities of the country's life. In this regard, when analysing Colombian cinematography, the most productive is the expansion of the boundaries of research in the field of historical memory, an appeal to the problem of violence and overcoming the trauma of the past.
Spain at the End of the 19th – beginning of the 20th Century in the Russian Socio-Political Discourse
Authors:   independent researcher, Natalia Samsonova
Published: April 2021

The article studies the response of the Russian reading public to the socio-political situation in Spain at the end of the 19th – beginning of the 20th century (the Spanish-American War, Tragic Week of 1909, the manifestation of regionalism and anti-clericalism, caciquism, the development of the ideas of socialism, working class movement). The author analyses common and different things in socio-political processes that were taking place in Russia and Spain of that period as well as the pe-culiarity of Russia`s perception of the Spanish events. In the `90s of the 19th century the Spanish-American War of 1898 acted as an impedi-ment to the dynamics of the image of Spain. The similarity of the socio-political situation, social upheaval in Spain and Russia of the end of the 19th – beginning of the 20th century increase the urgency of the “vision” of Spain by Russian society, make its perception in Russia more fragmented.

Çalışmamızın amacı, ultrasonografi (US) eşliğinde kesici iğne biyopsi (KİB) sonucu fibroepitelyal lezyon (FEL) olan lezyonların klinik ve US bulgularını, patolojik ayrımda kullanılan Ki-67 indeksini, eksizyonel biyopsi sonuçlarıyla karşılaştırarak ayırımda yararlı olabilecek bulguların araştırılmasıdır. 2009-2013 yılları arasında US eşliğinde KİB yapılmış 50 olguda, sonucu FEL olan 53 lezyon değerlendirilmiştir. Elliüç lezyonun 43’ü histopatolojik olarak FA, 10 tanesi de filloides tümör (FT) tanısı almıştır. Hastaların klinik bulguları, lezyonların BIRADS sınıflamasına göre yapılan ultrasonografik özellikleri ve KİB preparatlarının Ki-67 proliferatif indeks değerleri belirlenmiştir. Ayrıca meme radyolojisi konusunda 20 yıllık deneyim olan bir radyolog, eksizyon sonuçlarını bilmeden, lezyonların sonografik görüntülerini yorumlamıştır. Buna göre hiçbir klinik ve ultrasonografik parametrenin FA ve FT ayrımında özgün olmadığı sonucuna ulaşılmıştır. KİB preparatlarından yapılan Ki-67 proliferatif indeks değerleri de ayırıcı tanıya katkı sağlamamıştır. Ancak meme radyolojisi konusunda uzman radyoloğun öngörüsü ile cerrahi sonuçlar arasında istatistiksel olarak anlamlı uyumluluk bulunmuştur. Bu nedenle KİB sonucu FEL gelen ancak uzman radyoloğun benign olarak yorumladığı seçilmiş olgularda yakın takip alternatif bir seçenek olarak değerlendirilebilir.

Preparation of biscuit incorporating lemon peel powder can be a new approach in formulating fortified fast food. This investigation was made to evaluate quality of prepared biscuits with lemon peel powder. The effect of temperature on drying time and physiochemical properties of lemon peel powder and their effects on biscuits were also examined. Two drying temperatures (650C and 750C) were employed for both blanched and unblanched lemon peel. The formulated biscuit samples incorporating 1 % lemon peel powder were compared with control biscuits which were prepared with 100% wheat flour. It took longer time (18 hr) for drying of blanched sample at 65 0C whereas shorter time (8 hr) was required for that of blanched sample at 750C. There was a significant decrease in the physiochemical properties of lemon peel powder with the increase of temperature except protein and fibre content. In addition, moisture content of the unblanched sample was found to be lower than the blanched sample at the same temperature. Significantly higher ascorbic acid was obtained by the unblanched samples. Protein and fibre content for both unblanched and blanched sample at the same temperature were found to be higher. All the samples were significantly different at 5% level of significance for overall acceptability. Biscuits prepared with unblanched dried lemon peel powder (at 650C) sample secured the highest score in case of all the sensory parameters. Therefore, quality fortified biscuit can be prepared commercially by incorporating 1 % lemon peel powder in wheat flour for the fast food consumer.

Towards the Soyacene: Narratives for an Environmental History of Soy in Latin America's Southern Cone.
Authors: Da Silva Claiton Marcio , De Majo Claudio
Published: April 2021

This article provides an historical analysis of soybean farming in the most productive region of the world: Latin America’s Southern Cone, with particular attention for Argentina, Uruguay, Paraguay and Brazil. Drawing from the premise that current narratives on soybean cultivation and commercialization have mostly focused on quantitative data of a global scope, this article discusses the potential of scholarly narratives informed by the critical tools of environmental history. Moreover, it proposes the adoption of a new term sublimating the multilayered history of soybeans in the Southern Cone: the Soyacene. This term attempts to shape an original narrative of soybean production in the age of the Great Acceleration, deconstructing misleading historical assumptions. Moreover, by critically discussing the impacts of soybean production, the Soyacene strives to produce a non-essentialist historical narrative in which the diverging interests of different social layers (e.g. governmental actors, private corporations, small farmers and indigenous populations) are addressed with contextualized critical tools.
Geografia Histórica do Caminho do Ouro na Serra da Estrela (RJ), Sudeste do Brasil: barreira, fronteira e permeabilidade.
Authors: Fernandez Vicente Leal E. , Sales Gabriel Paes da Silva , Machado Ana Brasil , Solórzano Alexandro
Published: April 2021

A Serra da Estrela (RJ) é resultado da histórica relação entre cultura e natureza, atestando as grandes transformações ocorridas a partir da abertura do Caminho do Ouro. Objetivou-se compreender como a exploração de minerais preciosos no interior do Brasil, que se conectou com o litoral através de caminhos de escoamento com a transposição de barreiras físicas, levou à transformação da paisagem. Assim, investigamos as marcas da história da paisagem do Caminho do Ouro, na Serra da Estrela, um trecho específico com uma rica Geografia Histórica. Para isso, realizamos um levantamento bibliográfico a partir da investigação de estudos referentes à área junto com investidas de campos exploratórios a fim de inventariar os vestígios humanos impressos na paisagem (tais como carvoarias e ruínas). Ficou evidente que o ganho de importância da Serra da Estrela está diretamente relacionado com a tentativa de melhoramento no escoamento do ouro. Essa tentativa, por sua vez, tornou-se necessária a partir das dificuldades impostas pela fronteira física da Serra do Mar. Com isso, a Serra da Estrela passou a ser uma das localidades mais importantes do século XVIII, sendo palco de um dos mais valiosos capítulos da história do Brasil. É inegável que a abertura do Caminho do Proença influenciou diretamente na configuração socioespacial da Serra da Estrela, assim como da cidade do Rio de Janeiro e Petrópolis, sendo um marco histórico para o período de grandes transformações que se sucederam. Como marcas dessa história observamos as ruínas das casas da Fazenda Mandioca do Barão de Langsdorff, assim como as dez carvoarias encontradas que evidenciam o uso da floresta como fonte energética em algum momento da história. Dessa forma, a Serra da Estrela reflete os diferentes aspectos econômicos, sociais e culturais que se deram a partir da abertura do Caminho do Ouro até o presente.

To understand arguments, that is, to identify positions in a given a controversy, and to reconstruct the relationship between premises and conclusions; and to respond to them taking grounded point of views, is one of the most important competencies of digital citizen nowadays. However, there is scarce knowledge regarding adolescent argumentation skills (both in its comprehensive and productive aspects) in Chile. This study is aimed at describing Chilean sixth graders skills of argument comprehension and written production. 228 students (129 female) of nine schools in Santiago participated in the study. Students answered two tasks measuring argument comprehension and written production adapted from Reznitskaya and Wilkinson (2017). Results showed moderate systematic and significant correlations between the achievement in the two tasks. Students had more difficulties with writing than understanding arguments. Moreover, while understanding pro and con arguments was equally challenging, writing reasons to support an alternative position was the most difficult goal to achieve. Girls outperformed boys in writing arguments. Results significance and implicancies are discussed.

Published: April 2021

El propósito de esta investigación es explorar cuáles son los perfiles de escritores respecto a la calidad de las producciones argumentativas, así como establecer relaciones de estos perfiles con los recursos de lenguaje académico (RLA) que los estudiantes despliegan. 126 estudiantes chilenos de 8º básico de tres establecimientos educacionales escribieron un ensayo sobre el uso del tablet en la sala de clases. Para evaluar la calidad se validó una rúbrica y se utilizó el programa CHILDES para codificar diversos RLA. Para determinar los perfiles se realizó un análisis de clases latentes. Un 69% de los estudiantes se clasificaron en el perfil denominado emergente. El resto de los estudiantes pertenece al segundo perfil, denominado en desarrollo. En estos dos perfiles se analizó el uso de RLA. En el perfil emergente se observan dos clases de estudiantes que se diferencian sustancialmente en el uso (por presencia y/o ausencia) de nominalizaciones y vocabulario transdisciplinar. El perfil en desarrollo también presenta dos clases: una tiene mayor frecuencia, para quienes el uso de recursos es homogéneo. En cambio, el segundo grupo se caracteriza por el despliegue de vocabulario transdisciplinar, nominalizaciones y marcadores deónticos. Se concluye que los estudiantes necesitan más oportunidades para aprender a construir argumentaciones y desplegar recursos de lenguaje académico con el objetivo de potenciar sus puntos de vistas.

Закінчення Другої світової війни і полон японської армії радянськими військами для подальшого їх трудового використання на території СРСР засвідчили виникнення нового глобального процесу, який надалі отримав назву «холодної війни». Радянський Союз продемонстрував гнучку реак- цію на перспективу військового протистояння з США в умовах ядерної загрози. Перебування військовополонених японської армії на території СРСР в якості робочої сили було використано для ідеологічної обробки солдатської маси і підготовки діяльного активу для комуністичної пар- тії Японії. Метою політичної індокрінації в кінцевому рахунку можна вважати встановлення радянського контролю над внутрішньою і зов- нішньою політикою Японії і недопущення повного контролю над Японією з боку США.

The aim of this research is to depict foreign entrant students’ preparedness for studies in an international Master’s degree programme of physics at a Finnish university in order to lay the ground for a research-based development of the study programme. Interviews were conducted with the academic staff involved in the programme to investigate their views on the international physics students as learners. Conceptual tests were deployed to assess international students’ conceptual understanding of the areas fundamental to acquiring a solid expertise in physics. To enrich the data, a survey was conducted to obtain information about students’ physics-related epistemological views. Both qualitative and quantitative methods were used for the data analysis. The main results suggest that the entrant international students comprise a very heterogeneous group with regard to their preparedness for commencing physics studies. The staff were specifically concerned with the international students’ pre-knowledge of physics, a notion that is supported by the test results. Suggestions based on present findings are made for further development of international degree programmes such as the one considered in this article.

Abstract:Chili is a production cropthatis much needed by the  community. Good care is needed to increase the production of chili plants. Production of chili plants will decrease if the types of diseases that attack are not considered. To find out about chili plant diseases, farmers only look at the disease without knowing the symptoms that appear beforehand so that it will affect the production of chili plants.So that we need experts who understand the symptoms of disease in chili plants.The existence of experts can be replaced by a system designed to detect symptoms of disease in chili plants.The expert system to be designed is web-based using the case-based reasoning method.This expert system is expected to help increase the productivity of chili plants.            Keywords:expert system; chili; case-based reasoning; chili plants.  Abstrak:Cabai merupakan tanaman produksi yang banyak dibutuhkan oleh masyarakat.

Published: April 2021

Mango contains about 20 vitamins and minerals such as iron, copper, potassium, phosphorus, zinc, and calcium. The freshness of the ripe mango will taste sweet. The level of ripeness of the mango fruit can be seen from the texture of the skin and skin color. Ripe mangoes have a bright, fragrant color and a smooth skin texture. The problem found in mango segmentation is that the image of the mango fruit is influenced by several factors, such as noise and environmental objects. In measuring the maturity of mangoes traditionally, it can be seen from image analysis based on skin color. The mango peel segmentation process is needed so that the classification or pattern recognition process can be carried out better. The segmented mango image will read the feature extraction value of an object that has been separated from the background. The procedure on the image that has been analyzed will analyze the pattern recognition process. In this process, the segmented image is divided into several parts according to the desired object acquisition. Clustering is a technique for segmenting images by grouping data according to class and partitioning the data into mango datasets. This study uses the Fuzzy C Means method to produce optimal results in determining the clustering-based image segmentation. The final result of Fuzzy C-based mango segmentation processing means that the available feature extraction value or equal to the maximum number of iterations (MaxIter) is 31 iterations, error (x) = 0.00000001, and the image computation testing time is 2444.913636

Changes of extracellular matrix of rat cornea after exposure to hypoxia
Authors: Mahelková G , Korynta J , Moravová A , Novotná J , Vytášek R , Wilhelm J
Published: April 2021

The purpose of the study was to check whether hypoxia of
corneal tissue increases the collagenolytic activity due to release
of reactive oxygen and nitrogen species. Rats were exposed to
hypoxia 10 % O2 for 4, 14, and 21 days. The radical tissue injury
was measured by the level of nitrotyrosine and changes in the
lipoperoxide-related fluorophores. Collagen protein composition
was analyzed by slab gel electrophoresis. The activity of
gelatinolytic enzymes was studied using the zymography. The
vascularization of the corneas was measured. We found no
differences in the corneal tissue in the gel electrophoretic profile
of collagenous proteins and gelatinolytic activity between
normoxic and hypoxic rats. We did not find any sign of radical
tissue injury. There were no changes in the vascularization of
corneas after exposition to hypoxia. The environmental 10 %
hypoxia does not induce radical tissue injury and an increase of
collagenolytic activity in the rat cornea.
Advanced glycation end-product pentosidine accumulates in various tissues of rats with high fructose intake
Authors: Mikulíková K , Eckhardt A , Kuneš J , Zicha J , Mikšík I
Published: April 2021

The slowly metabolized proteins of the extracellular matrix,
typically collagen and elastin, accumulate reactive metabolites
through uncontrolled non-enzymatic reactions such as glycation
or the products arising from the reaction of unsaturated long
chain fatty acid metabolites (possessing aldehydic groups). A
typical example of these non-enzymatic changes is the formation
of advanced glycation end-products (AGEs), resulting from the
reaction of carbohydrates with the free amino group of proteins.
The accumulation of AGEs and the resulting structural alterations
cause altered tissue properties (increased stiffness, reduced
elasticity) that contribute to their reduced catabolism and to their
aging. Posttranslational nonenzymatic modifications of the
proteins of the extracellular matrix (the formation of a typical
AGE product - pentosidine) were studied in three types of tissue
of three rat strains subjected to a high-fructose diet. Chronic
(three-week) hyperglycemia (resulting from fructose loading)
caused a significant increase in pentosidine concentration mainly
in the aorta and skin of the three rat strains (Lewis, Wistar and
hereditary hypertriglyceridemic rats).
