Authors: Raigar M.B. , Tejasvi S. , Mandal K.
Published: October 2022

Tamarind Kernel-Power (TKP), a naturally occurring polysaccharide, has been used for the synthesis of a novel ion exchange resin, namely Tamarind triazine methyl sulphamic acid (TTMSA). The resin acts as a scavenger for toxic metal ions from the effluents of various industries. Characterization of resin has been done by FTIR, TGA and elemental analysis. Various physico- chemical properties of resin were analyzed including ion-exchange capacity, % nitrogen content, bulk density, bulk volume and moisture content. The resin was found to be stable with good reproducibility, good ion exchange capacity and selectivity for toxic metal ions. The partition coefficient values and percentage adsorption of various metal ions on the newly synthesized resins were determined by batch method with the help of Atomic Absorption spectrophotometer. The efficiency of resin was studied for up to 10 cycles. Analysis has shown that the adsorption of different metal ions on TTMSA resin followed the order Fe+2 >Cu+2> Zn+2>Pb+2>Cd+2. A suitable and cost-effective method was employed to reach the result of this experiment.

Published: October 2022

The present study describes the synthesis and characterization of some transition meal complexes derived from azo ligand derived from condensation 4-hydroxycoumarine and 2-aminobenzothiazole. The azo ligand was characterized by C.H.N.S elemental analyses, GC-Mass spectroscopy, H NMR and FT-IR spectra. The metal complexes with the new azo dye were isolated by the direct reactions of the metal chlorides of cadmium(II), zinc(II), cobalt(II), nickel(II) and copper(II) ions with the alkaline solution of free ligand to afford the following complex [ML(H2O)2Cl] where M=Co(II), Cd(II), Cu(II) and Zn(II). The results obtained from FAAS, elemental analyses, UV-visible spectra, LC-MS and magnetic susceptibility measurements confirmed the tetrahedral environment for [CdLCl] complex and octahedral environment around copper(II), cobalt(II) and nickel(II) complexes. The time and mole ratios factors were studied to recommend the optimized conditions of metal complexes formations and the observed data was investigated for the deprotonation of the azo-dye at pH 6-7.0 with 6.5 minutes as time of reaction to afford the crystalline complexes.

Published: October 2022

Повышение качества травяных кормов остаётся одним из важнейших направлений укрепления кормовой базы. Низкое качество основных объёмистых кормов приводит к значительному увеличению количества зерна в рационе животных. Динамика изменения влажности скошенной растительной массы, потери объёмной массы и питательных веществ трав в зависимости от погодных условий, длительности уборки, видов технологических операций и применяемых технических средств определяют качество растительной массы. Цель работы — оперативный контроль влажности свежескошенной и подвяленной травы в интенсивных технологиях заготовки кормов без дополнительной подготовки проб с использованием макета влагомера. Экспериментально исследованы характеристики пространственной чувствительности планарного ёмкостного датчика макета влагомера трав. Определена величина эффективного проникновения ЭМП датчика в растительный материал.

Increase in grass fodder quality keeps the leading position in forage security improvement. Low quality of top bulky feeds results in significant raise of grain forage in livestock diet. Variation in moisture content of cut mass, loss of bulky mass and nutrients due to weather conditions, length of harvesting period, technological practices and equipment affect plant mass quality. The research aimed at monitoring of moisture content of fresh and air-dried grass, using moisture tester prototype without extra probe preparation. The prototype was analyzed in spatial sensitivity of planar capacitive sensor. We determined the value of effective penetration of sensor electromagnetic field into plant material. Microcontroller unit was developed together with a respective software, allowing data display mode, storage of calibration parameters, creation of data base, calculation of mean values and connection to an external computer. Prototype tests in field showed its adequate response to required criteria in intensive feed preparation technology. The conducted work provided structural concept of measurements, developed and tested new field device. The moisture tester determined the water content within a range of up to 85% as well as grass electrical conductivity directly in windrows and swath with no probe preparation.

Authors: Дронов А.
Published: October 2022

Исследования проводились в Брянской области в 2015–2017 годах. В статье представлены результаты совершенствования отдельных элементов технологии возделывания сорго-суданковых гибридов в юго-западной части Нечернозёмной зоны. Целью работы являлось изучение эффективности комплексного применения минеральных удобрений на посевах сорго-суданковых гибридов. В полевом стационарном опыте на серой лесной легкосуглинистой почве выявлено существенное влияние азофоски, борофоски и аммиачной селитры на рост, развитие, урожайность и качество кормовой массы сорго-суданковых гибридов. Установлено, что применение минеральных удобрений оказало положительное влияние на высоту растений и интенсивность побегообразования. Урожайность кормовой массы в вариантах с внесением азотных удобрений варьировалось довольно сильно. Наибольшую урожайность сухой (14,8–15,8 т/га) и зелёной массы (65–71 т/га) формировали посевы гибридов Сабантуй F1 и Солярис в варианте с подкормкой N90 на основном фоне N60P60K60. Менее урожайными были гибриды Славянское поле 15 F1 и Приусадебный F1 с урожайностью сухой массы 13,1 и 13,7 т/га соответственно. Наиболее существенная разница отмечалась между удобренными и неудобренными вариантами. Влияние различных фонов минерального питания (азофоска и борофоска — N60P60K60 и P60K60 соответственно) заметно сказалось на питательности корма из сорго-суданковых гибридов. Анализ лабораторных данных позволил установить достаточно широкие различия между изучаемыми гибридами по биохимическому составу кормовой массы.

The experiment took place in the Bryansk region in 2015–2017. The article presents the results on improvement of individual elements in the cultivation technology of sorghum-sudangrass hybrids in the south-west of the Non-Chernozem area. The aim was to evaluate the influence of mineral fertilization on hybrid performance on gray forest soil with a low clay content. NPK, PK and ammonium nitrate significantly affected growth, development, yield and quality of forage mass. Mineral fertilizers positively influenced plant height and intensity of shoot formation. Yields of forage mass varied strongly in variants, treated by N-fertilizers. Hybrids “Sabantuy F1” and “Solyaris”, treated by N90 had the highest dry (14.8–15.8 t ha-1) and green mass productivities (65–71 t ha-1) on the background of N60P60K60. Hybrids “Slavyanskoe pole 15 F1”and “Priusadebnyy F1” were less productive, producing 13.1 and 13.7 t ha-1 of dry mass, respectively. Fertilized and unfertilized variants differed the most. Different mineral backgrounds (N60P60K60 and P60K60) had significant effect on forage nutritional value. Lab results showed strong differences in forage biochemical composition among the hybrids.

Исследования проводились в степной зоне Минусинской впадины и лесостепи Алтайского Приобья. В статье представлены результаты исследований противоэрозионной эффективности приёмов биологизации земледелия и технологий обработки почвы. Были проанализированы многолетние данные научных учреждений, расположенных в разных агроэкологических условиях в лесостепном и степном агроландшафтных районах. Длительные полевые опыты по изучению и сравнительной оценке технологий обработки почвы в сидеральных парах показали неодинаковую почвозащитную эффективность в разных почвенно-климатических условиях Средней Сибири. В степном агроландшафтном районе на эрозионно опасных землях для повышения почвозащитной роли сидеральных паров целесообразно применение плоскорезной обработки, позволяющей сохранить растительные остатки на поверхности почвы. При такой обработке выноса мелкозёма ветром на чернозёмах не наблюдалось, а при запашке вынос составил 2,5–8,1 т/га в год. В лесостепном агроландшафтном районе на склоновых землях оставленная в зиму стерня позволяла практически полностью предотвратить весенний смыв. Количество дней с пыльными бурями после освоения целинных и залежных земель в Хакасии в 1961–1965 годах достигало 5–13, в настоящее время при уменьшении площади сильноэродированной пашни и увеличения объёмов залежных земель пыльные бури прекратились. Парозанимающая культура (овёс летнего срока сева), а на склоновых землях осеннее мульчирование рапсом полностью предотвращали весенний смыв почвы. Выход зерна с 1 га севооборотной площади при запашке донника и плоскорезной обработке почвы почти одинаковый: соответственно 1,64 и 1,76 т/га.

Investigations took place in the steppe of Minusinsk Hollow and forest-steppe of the Ob region in Altai. The article reports on antierosion practices and tillage technologies. Investigations analyzed the data of long-term experiments targeting different ecological conditions in forest-steppe and steppe regions. Long-term field trials showed unequal soil-protecting effect of different tillage technologies in various soil-climatic zones of the Central Siberia under green-manured fallow. To increase soil-protecting influence of green-manured fallow in the steppe plowing is necessary that allows preservation of plant residues on soil surface. Such a practice prevented fine soil from being blown-away by wind while plowing under resulted in fine soil removal of 2.5–8.1 t ha-1 per year. In the forest-steppe crop residues left over winter almost completely prevented soil outwash on slope lands in spring. Number of days with dust storms reached 5–13 in Khakassia in 1961–1965 after virgin and long-fallow land cultivation. Nowadays decrease in high-eroded land area and increase of long-fallow lands stopped dust storms. Fallow crop (spring oats) and top manuring of slope soil by rapeseed in autumn prevented soil washout in spring. Grain yield made up 1.64 and 1.76 t ha-1 when plowing under melilot and soil plowing, respectively.
Basic parameters of cow milk productivity when feeding with the “Fibraza” additive
Authors: Буряков Н. , Хардик И.
Published: October 2022

Исследования проводились в СПА(К) «Кузьминский» Сергиево-Посадского района Московской области в 2017–2018 годах. Для достижения высокого уровня молочной продуктивности всё сложнее найти компромисс между состоянием здоровья животного и кормами: ведь, чем выше продуктивность коров, тем выше нагрузка на их пищеварительную систему, которая, в случае сбоя, повлияет на работу и функции всех систем организма. Таким образом, актуально в составе рационов высокоудойных коров применение кормовых добавок, позволяющих повысить доступность и степень усвоения питательных веществ корма, с целью перераспределения энергетических затрат организма с переваривания корма на производство продукции. В связи с этим особого внимания заслуживают комплексные ферментные препараты, действие которых направлено на активацию рубцовой ферментации за счёт входящих в них биологически активных веществ. На трёх группах высокопродуктивных коров чёрно-пёстрой голштинизированной породы изучали влияние кормовой добавки «Фибраза» на молочную продуктивность за 305 дней лактации. Исследуемая добавка оказала различное влияние на продуктивные показатели животных и лучший эффект проявила при норме скармливания 20 г/гол./сутки. В указанной дозировке в среднем на одну корову опытной группы за лактацию увеличение среднесуточного удоя молока 4% жирности составило 36,1 кг против 34,2 кг в контрольной группе, или на 5,56%. В среднем на одну корову опытной группы было надоено 11 168 кг молока с массовой долей белка 3,32% и жирностью 3,93% против 10 908,7 кг молока с массовой долей белка 3,26% и жирностью 3,74% в контрольной группе.

Investigations took place at SPA(K) “Kuzminskiy” of the Moscow region in 2017–2018. Pursuing high level of milk productivity makes it more difficult to find a balance between animal health and fodder. The higher cow productivity the higher the pressure on its digestive system that can negatively affect functions of all the organism systems if impaired. Therefore, use of feed additives is of great importance since they improve nutrient availability and digestibility as well as redirect metabolic costs from forage digestion to milk production. From this perspective complex enzyme preparations deserve a special attention. They are able to activate ruminal fermentation due to their biologically active substances. “Fibraza” effect was tested on milk yield of high-productive Holstein black-and-white cows for 305 days of lactation. The best feeding rate was 20 g/head daily resulting in milk yield increase (4% of fat content) of 36.1 kg versus 34.2 kg of the control group or 5.56%. One cow of the experimental group provided 11 168 kg of milk on the average containing 3.32% of protein and 3.93% of fat while the one of the control group produced 10 908.7 kg of milk containing 3.26% of protein and 3.74% of fat.

Are the chemical families still there? exploration of similarity among elements
Authors: Llanos Ballestas Eugenio , Leal Wilmer , Bernal Andrés , Jost Jürgen , Stadler Peter F.
Published: October 2022

The Periodic Table (PT) is perhaps the most famous and widespread icon of chemistry. It orders chemical elements by their nuclear charge and groups them into families according to their similarity. Such arrangement was built using data about formulae of few compounds available in 19th century. Since then, the number of compounds has grown exponentially during the 20th and 21st centuries, and new types of compounds have been obtained that were unknown to pioneers, rising the question about the validity and generality of the PT. Can these patterns be extracted from current data or are they constrained to a particular chemical domain? To answer this question we conducted a Big Data exploration of chemical similarity using formulae of compounds reported since around 1800. We found that the similarities between elements of the same family are resilient to attacks and are ubiquitous along chemical contexts. We also found that PT groups approach true equivalence classes, being the most symmetrical and transitive on our data. These features point to an underlying structure in the PT ruling the similarity between elements, which agrees with its fundamental nature. Time analysis revealed that since around 1980 all similarity relations are waning by an increasing production of unique formulae on almost all elements, leading to a singularization of elements. Nonetheless, PT families tend to be more frequently found, showing they prevail over any other similarity pattern.
The Competition between Hydrogen, Halogen, and Covalent Bonding in Atmospherically Relevant Ammonium Iodate Clusters

Published: October 2022

Iodine containing clusters are expected to be central to new particle formation (NPF) events in polar and mid-latitude coastal regions. Iodine oxoacids and iodine oxides are observed in newly formed clusters, and in more polluted mid-latitude settings, theoretical studies suggest ammonia may increase growth rates. Structural information was obtained via infrared (IR) spectroscopy and quantum chemical calculations for a series of clusters containing ammonia, iodic acid, and iodine pentoxide. Structures for five of the smallest cationic clusters present in the mass spectrum were identified and four of the structures were found to preferentially form halogen and/or covalent bonds over hydrogen bonds. Ammonia is important in proton transfer from iodic acid components and also provides a scaffold to template the formation of a halogen and covalent bonded backbone. The calculations executed for the two largest clusters studied suggested the formation of a covalent I3O8- anion within the clusters.

Published: October 2022

Integrated catalysis is an emerging methodology that can streamline the multistep synthesis of complicated products in a single reaction vessel, achieving a high degree of control and reducing the waste and cost of the overall process. Integrated catalysis utilizes spatial and temporal control to couple different catalytic cycles in one pot. This primer discusses commonly employed spatial and temporal approaches and their underlying mechanisms, and elaborates on how the integration of spatially and temporally controlled catalysis in one pot can deliver the synthesis of complex products with high efficiency. We highlight recent advances, analyze current applications and limitations, and provide an outlook for the future development of integrated catalysis.

Published: October 2022

The risk of morbidity and death in patients with chronic kidney disease (CKD), formerly known as chronic renal failure (CRF), is increased by a number of comorbidities, including infections, cardiovascular disease (CVD), and anaemia. The second most common reason for death in this population is infections. Antibiotics can accumulate in the body and have harmful consequences when given to CKD patients without the necessary dosage modification and in an illogical manner. The purpose of this particular study was to compare the standard treatment protocol with the reasoning and prescribing patterns of antibiotics administered for infections in CKD patients staged 3-5 in the nephrology department of a single Center in Kerala’s Kottayam district. The medical records of 272 patients who met the inclusion and exclusion criteria and were admitted to the nephrology department between November 2019 and November 2020 were examined as part of single-centred retrospective research that was created to address this. Surprisingly, just 45 percent  of the prescriptions were rational, while 55 percent of them were nonsensical. Additionally, we discovered that 23 percent of antibiotic selections went outside accepted therapeutic standards. Thus, we could conclude that the prescriber must use the utmost caution while prescribing to a patient with CKD to prevent future difficulties.

Quinoline and its derivatives represent an important class of nitrogen containing heterocycles because they are useful intermediates in organic synthesis and biological activities such as antiasthmatic, anti-inflammatory, anti- cancer, and antimalarial activity. A quinoline containing eight compounds was successfully synthesized and characterized by FT-IR, 1H NMR, 13C NMR and mass spectral analysis. Therefore, the synthesis of new quinoline derivatives with strong pharmacological activity is important in medicine. There is significant research focused on the development of new quinoline-based structures and new methods of synthesis. In this research study, new quinoline derivatives were synthesized and the synthesized compounds were characterized by several spectroscopic techniques, the biological activity of these compounds was evaluated using lung cancer cell lines and molecular modeling in an enzymatic system. The synthesized eight new compounds were tested for their potential activity in lung cancer cell lines. Eight synthesized compounds (K1- K8) were evaluated for their cytotoxic activities. The anticancer test showed that the quinoline compounds K2, K3 and K4 show good anticancer activity. Among them, K2 and K4 were shown to be dose-dependent, with K4 having the highest toxicity at 250 µM and K8 having the highest toxicity at 125, 250, and 500 µM, while K1, K2, K5, K6, and K7 were not cytotoxic.

The results are obtained on the basis of structural, dynamic and matrix analysis of the market. Considered the main problems of the dairy industry, including: reducing the number of dairy processing plants, reducing the number of cattle, the low level of technological equipment in production and lack of modern equipment for storage and processing of raw materials. As a consequence, such trends have led to a significant increase in the cost of production of raw milk and an expected increase in the price of finished products, which, in turn, has led to a reduction in demand for dairy products. Using SWOT- and PEST-analysis the properties of the milk and dairy products market of Ukraine as a whole, its subjects and their interaction have been studied and presented in a systematic form. Proposals to improve the state of the market of milk and dairy products in Ukraine are formulated. The proposals are grouped into the following areas: economic activity, technology and resources and state support. The combination of state support measures, entrepreneurial efforts, and reliance on international experience will preserve food security in Ukraine and provide the population with high-quality dairy products in the required quantity, reduce imports, and introduce advanced resource-saving technologies. There is a potential opportunity for Ukrainian producers to reach new international markets, but on condition that product quality indicators are met.

Published: October 2022

The article developed a mathematical model of personnel management, taking into account the specifics of the activities of IT companies. The relevance of this study is due to the fact that the tasks of personnel management are subjective. This creates certain difficulties when choosing a mathematical apparatus for building a model for the effective distribution of specialists on projects in IT companies. The purpose of the research is to study modern methods and models of personnel management and develop a mathematical model for the selection of specialists with the necessary qualifications for an IT team. The article sets the following tasks: to analyze the theoretical and methodological foundations of economic and mathematical modeling of personnel management; to develop a personnel management model in the IT labor market. The authors describe the features of the activities of recruiting specialists in IT companies. The essence of the methods of personnel management in the IT labor market is analyzed. The specificity of the work of HR-managers (human resource managers) in outsourcing and outstaffing IT companies is considered. The use of a systematic approach to personnel management is proposed, in which an IT enterprise is considered as a subsystem of an economic system of the "fragment-aspect" type. The economic and mathematical model for recruiting specialists in an IT team, developed in the article, includes two components: "Model for the formation of the qualitative composition of IT personnel" and "Model for the formation of the quantitative composition of IT personnel". Forming an effective IT team requires a certain number of specialists with professional skills and universal competencies. The constraint conditions of the model describe the qualitative characteristics of applicants, such as profession, qualifications, hard skills and soft skills of candidates, and quantitative requirements. The model is built on the basis of heuristic methods for managing socio-economic systems and allows you to form a step-by-step list of applicants for vacancies in an IT team, taking into account the professional and personal qualities of specialists and the stated requirements for them from employers. The objective function is to minimize the total time spent by HR managers to form an effective IT team, taking into account the needs of customers. The result of the model's work is the formation of a list of candidates that should be recommended for concluding an agreement with customers.

Probability of poverty: PPI analysis by machine learning
Authors: Kosiashvili D.
Published: October 2022

Recently, poverty has been recognized as a global problem. Poverty Probability Index (PPI) is one of the tools to measure it. Based on the survey results on household characteristics and asset ownership, the PPI calculates the likelihood that a household lives below the poverty line. PPI is currently used by more than 400 organizations around the world – international NGOs, social services, donors, investors, multinational corporations, government and other organizations in various sectors including agriculture, health, education, energy and finance. The most famous PPI-based projects include the “Hunger” and “Electronic Warehouse” projects, Starbucks' strategy for Colombian farmers. However, the basic model with two classes (poor-rich), which underlies the index, does not classify the majority of the population with an average level of income, which has a chance of both getting rich and falling into the poor class over time and under the influence of various exogenous factors. Therefore, the work suggests a clustering model, which allows to identify 3 categories of the population: in addition to the poor and the rich, it also considers people with average earnings. 1) The class of the poor includes people of middle and old age living in villages. In most cases, these are married women with low literacy rates, who do not have their own business, bank account, and often a telephone. 2) An average earner is often a young married man with a good education. In most cases, he is neither an investor nor a business owner, he does not have a home to rent. At the same time, he usually owns at least 2 phones. 3) The class of the rich includes people of both sexes, both single and with a family. These are highly educated people who most likely have a business, investments, apartments for rent. The proposed model will help to develop more accurate tools for both poverty alleviation and prevention.
HISTÓRIA, EDUCAÇÃO E PRÁTICAS CULTURAIS DA INFÂNCIA NA OBRA DE GILBERTO FREYRE
Authors: SILVA ARAÚJO ALVES LAURA MARIA , DA SILVA GUIMARÃES JACQUELINE TATIANA
Published: October 2022

Este artigo surgiu da leitura detalhada das obras de Gilberto Freyre Casa-Grande & Senzala e Vida Social no Brasil nos Meados do Século XIX, na qual percebemos que a criança se apresentava como protagonista da narrativa. Falar sobre a infância parecia ser um grande desejo de Gilberto Freyre. Em 1921, ele confidenciou em seu diário que desejaria escrever sobre a infância brasileira. Embora não tenha materializado esse desejo, nos anos 20 do século passado, Gilberto Freyre timidamente escreveu quatro artigos para o Diário de Pernambuco falando das crianças, seus livros e brinquedos. Da leitura das duas obras destacamos cinco categorias de análise: (1) mortalidade e abandono de crianças; (2) práticas culturais e os cuidados com a criança; (3) superstições na proteção da criança; (4) rituais nos funerais e sepultamentos de crianças; (5) castigos corporais e disciplinamento da criança. Para resgatar a infância no Brasil, Freyre buscou dados em vários documentos. Os discursos narrativos sobre a infância foram construídos a partir de relatos de viajantes, narrativas de romances e contos, poemas, narrativas de historiadores, anúncios de Jornais, teses de medicina, pareceres médicos, congressos médicos etc. A narrativa de Gilberto Freyre é repleto de uma polifonia discursiva que retratam a infância do Império a República. Nas duas obras verificamos que a cultura indígena, portuguesa e negra impregnou pensamentos, comportamentos e hábitos que até hoje estão nas práticas culturas e educacionais de nossas crianças.
A HISTÓRIA DAS CIÊNCIAS NO LICEU DO CEARÁ: ENTRE ATOS E FATOS – DENÚNCIAS DO PROFESSOR RODOLFO TEÓFILO
Authors: DE BARROS FAÇANHA ALESSANDRO AUGUSTO
Published: October 2022

Este estudo trata de um recorte histórico da ação política do Governo Accioly, nos primeiros anos do século XIX, no Liceu do Ceará, com base na análise de documentos, regulamentos e atos da reforma educacional daquele governo, com ênfase nas análises do Decreto Benjamin Constant de 1890, do Regulamento de 1905, do Regimento de 1915 e da Reforma de 1922, na intenção de desvelar as condutas despóticas do governo da época em relação à perseguição política encetada ao professor de Ciências Naturais, Rodolfo Teófilo, denunciadas pelo próprio professor na obra intitulada Violência, de 1905. Com base na pesquisa bibliográfica, caracteriza o referido acontecimento, a partir de um relato do professor perseguido, o qual retrata ainda a sua iniciativa de defesa, por meio de documentos impetrados contra o governo, bem como a sua indignação diante daquilo que foi intitulada de reforma Aciolina. A partir desse foco é possível observar as intenções e disputas da política local interferindo nos rumos da educação naquele Liceu, por meio de uma ação de consequências certamente desastrosas para o ensino de Ciências, naquela época, a qual se apresenta como uma área incômoda para o poder oligárquico fundado na tradição e contrário ao conhecimento científico moderno.
LINGUAGEM CINEMATOGRÁFICA COMO AGENTE NARRADOR DE HISTÓRIA E MEMÓRIA EM TANGO DE CARLOS SAURA
Authors: DE ABREU WERNER JULIANA
Published: October 2022

Buenos Aires. Metade do século dezenove. Uma política de fomento à imigração europeia traz às terras portenhas mais de seis milhões de imigrantes. Ao contrário do que o governo argentino esperava, as que compunham esse cenário não eram pessoas requintadas, conhecedoras de arte e ciência, muito menos mão de obra qualificada. Os imigrantes de pouca instrução e de poucos meios que passaram a fazer parte da população residente nos arrabais portenhos, assolados pela saudade de suas terras, buscando no ambiente prostibulário por uma natural comunhão, dão origem ao tango nas últimas décadas do século dezenove. Por volta da mesma época, os irmãos Lumière produzem o invento que chamariam de cinematógrafo, palavra de raiz grega que significa “registro do movimento”. Portanto, percebo o tango e o cinema como expressões contemporâneas. Esse artigo propõe analisar de que maneira a linguagem cinematográfica, bem como as escolhas estéticas do cineasta atuam como agente narrador de história e memória em Tango de Carlos Saura. Usando o aporte teórico dos Estudos Culturais e entendendo as produções cinematográficas como artefatos pedagógicos, busco perceber quais são os sentidos produzidos sobre o tango argentino na narrativa construída por Saura. Inicio meu exercício analítico a partir de um olhar atento sobre os elementos técnicos de cenário, iluminação e figurino empregados na construção da obra. Somado a isso, a linguagem cinematográfica utilizada por Saura, perceptível por meio dos planos, ângulos e movimentação de câmera, também são aspectos importantes que compreendem a análise.
