Tratado de Madri de 1750 e sociedade de cortes: elementos de um legado colonial jurídico internacional no Brasil independente
Authors: Capella Giannattasio Arthur Roberto
Published: April 2021

Resumo: A tradição jurídica reconhece o Tratado de Madrid (1750) como (i) resultado do gênio pessoal do diplomata luso-americano Alexandre de Gusmão, e (ii) um documento infrutífero e voltado apenas à resolução de conflitos territoriais entre Coroas ibéricas. Sem ignorar tal leitura, uma pesquisa qualitativa baseada em fontes primárias e secundárias e guiada pela noção de sociedade de Cortes permite vislumbrar nele um sentido estrutural mais profundo: replicar e manter caracteres de uma ordem internacional marcada pelos parâmetros de um corpus politicum mysticum. Argumentamos que (i) reconhecer tais elementos proporciona à historiografia jurídica brasileira nuances adicionais na avaliação de rupturas e continuidades entre América portuguesa e Brasil independente, pois (ii) o Tratado de Madri (1750) incorpora tradições que marcariam a política externa brasileira após sua emancipação política.Palavras-chave: corpus politicum mysticum, legado colonial brasileiro, inserção internacional do Brasil, uti possidetis, direito internacional como herança colonial.Abstract: Seeking asylum presents itself as a surviving strategy to a part of the Legal tradition recognizes the Madrid Treaty (1750) as (i) the result of the personal genius of the Portuguese-American diplomat Alexandre de Gusmão, and (ii) a fruitless document aimed only at resolving territorial conflicts between Iberian crowns. Without ignoring this reading, a qualitative research based on primary and secondary sources and guided by the notion of Court society allows us to glimpse a deeper structural sense: to replicate and maintain characters of an international order marked by the parameters of a corpus politicum mysticum. We argue that (i) recognizing such elements provides Brazilian legal historiography additional nuances in the assessment of ruptures and continuities between Portuguese America and Independent Brazil, since (ii) the Treaty of Madrid (1750) incorporates traditions that would mark Brazilian foreign policy after its political emancipation.Keywords: corpus politicum mysticum, brazilian colonial legacy, international insertion of Brazil, uti possidetis, international law as a colonial heritage

Authors: Vetrile S. T. , Shvets V. V. , Kuleshov A. A.
Published: April 2021

Authors analysed the outcomes of surgical treatment in 108 patients with scoliosis. Depending on surgical technique the patients were divided into 4 groups. The base of surgical procedures was different combinations of Harrington distractor with Luque rod as well as with segmental angular resection at the deformity apex. The efficacy of segmental angular resection that enabled to mobilize the rigid scoliotic deformity and increase intraoperative correction was detected. The combination of that procedure with the deformity correction by Harrington distractor and lateral traction by Luque rod allowed to achieve more marked correction and to preserve it to a greater degree and for longer time (2 years after operation 67,8% of achieved correction was preserved). It was also shown that fixation of corrective spine by Harrington distractor only did not provide considerable preservation of primary achieved correction in long term postoperative period (2 years after operation 47,3% of the achieved correction was preserved).

Published: April 2021

The purpose of this report is the determination of the diagnostic reliability of routine radiologic and CT examinations for pelvic injuries in children. The comparative analysis of these examinations and postmortem morphologic studies of pelvic spesimens was performed in 10 children, aged 2-12 years. It was shown that the X-ray method allowed to diagnose only 47.37% and CT method - 76.32% of all real pelvic injuries (by morphological data) in those children. However, the detectability of damage of the structures that formed the anterior pelvic semi-ring was 50% by radiologic examination, and 60% by CT examination, while for the structures forming posterior pelvic semi-ring it was 44.44% and 94.44%, respectively.

Danos em Frutos e Sementes de Hymenaea courbaril L. por Rhinochenus stigma (Linneu 1764)
Authors: Amador Mojena Pastor , Barreto Marliton Rocha
Published: April 2021

O desenvolvimento de insetos em frutos ameaça o potencial de germinação das sementes, sendo responsáveis por perdas em um número variado de espécies nativas e de valor econômico no Brasil. O jatobá é uma árvore grande, com 30 a 40 metros de altura, e possui tronco reto, com cerca de 2 metros de diâmetro, sendo bastante utilizado por populações tradicionais em função de suas diversas utilidades, a partir do uso da casca, das sementes, dos frutos, da seiva e das folhas, tendo seu mercado incentivado pelos vários produtos originados. Pesquisas realizadas em diferentes biomas brasileiros com espécies de árvores leguminosas destacam a predação de sementes e frutos por coleópteros broqueadores, afetando a qualidade da semente destinada à perpetuação da espécie. Portanto, este trabalho tem como objetivo avaliar os danos causados por Rhinochenus stigma em frutos e sementes de Hymenaea courbaril. Constatou-se que esse inseto foi responsável pelo consumo médio de 46,79% do peso de uma semente e que a porcentagem de germinação das sementes danificadas foi de apenas 3%. A predação de sementes por R. stigma possui um efeito direto sobre a qualidade fisiológica das sementes de H. courbaril e evitar esses danos são, significativamente, importantes para os coletores de frutos e sementes que o utilizam para confecção de artesanato, bem como para o uso em planos de reflorestamento.

Abstract
The development of insects in fruits threatens the  seeds germination potential and is responsible for losses in a varied number of native species and of economic value in Brazil. Jatoba is a large tree, 30 to 40 meters high, and has a straight trunk, about 2 meters in diameter, it is widely used by traditional populations due to its diverse uses from the use of bark, seeds, fruits, sap and leaves, with its market encouraged by the various originated products. Research carried out in different Brazilian biomes with legume tree species highlights the seeds and fruits predation by boring coleoptera, affecting the quality of the seed aimed at the species perpetuation. Therefore, this work aims to evaluate the damage caused by Rhinochenus stigma in fruits and seeds of Hymenaea courbaril. It was found that this insect was responsible for the average consumption of 46.79% of the weight of a seed and that the germination percentage of the damaged seeds was only 3%. The seeds predation by R. stigma has a direct effect on the physiological quality of H. courbaril seeds and avoiding these damages is significantly important for fruit and seed collectors who use it for making crafts, as well as for use in reforestation plans.

O elemento árabe en galego (I)
Authors: Frías Conde Xavier
Published: April 2021

A atención ao elemento árabe en galego dista moito da longa traxectoria dos estudos arabo-románicos nas súas linguas irmás, polo que é unha das cuestións pendentes na lingüística galega. Nos poucos traballos existentes indícase a pegada efémera ou inexistente da presenza árabe, mais os arabismos no léxico e na toponimia son moi superiores ao que xeralmente se cre. Así mesmo, os estudos portugueses só son válidos parcialmente, porque cómpre saber qué vocábulos árabes son exclusivos do galego, cales son máis antigos e por que as formas galegas presentan solucións diferentes ás portuguesas, como é a antigüidade cronolóxica na entrada dos arabismos en galego. De feito, dentro do sistema lingüístico galego-portugués cumpriría diferenciar tres zonas (a galega, a portuguesa setentrional e a portuguesa meridional), que se corresponden coas distintas épocas de entrada do superestrato árabe no idioma.
A expresión lingüística do significado de "causalidade"
Authors: Mosteiro Louzao Manuel
Published: April 2021

A relación lóxica de “causalidade”, segundo a cal todo efecto (q) está precedido no tempo dunha causa (p) que o xera, maniféstase lingüisticamente de diferentes formas, dependendo, entre outros factores, da natureza da propia causa (real ou hipotética), do nexo utilizado ou da posición das cláusulas. Estas, ao se poñeren en relación, dan lugar a diferentes clases de oracións (causais, finais, consecutivas, condicionais e concesivas) que presentan varios puntos de contacto, como o significado común de ‘causalidade’, a analoxía sintáctica (no tempo: acción anterior ou simultánea con relación á cláusula principal; no modo: uso do tempo indicativo ou subxuntivo; na disposición: maioría de inversión da orde, se ben leva consigo unha interpretación pragmática diferente) e a súa clasificación en oracións lóxicas e non lóxicas.

Finalmente, el documento ofrece una perspectiva sobre cómo avanzar hacia un pilar de ahorro voluntario para toda la población adulta generando un entorno regulatorio favorable, diseñando productos financieros inclusivos y asegurando que la tecnología alcance a más personas para ofrecer canales de ahorro sencillos y accesibles.
Query Optimization in a Blockchain-Based Land Registry Management System
Authors: Yadav Amrendra Singh , Kushwaha Dharmender Singh
Published: April 2021

Digitization of land records is not sufficient for preventing fraud cases, time delay, and brokers' involvement. Distributed Ledger Technology (DLT) is used for making this digitized record more secure and process it in a decentralized way, and reduces paperwork in selling and buying of land. Blockchain technology has come to the fore in recent years and is the center of technical discussion, with intuitive applications driven by its network architecture. It has been firmly established as one of the most important emerging technologies. This article aims to implement a land registry mechanism using blockchain technology and optimize searching of land records in blockchain. Interplanetary File System (IPFS) provides an infrastructure that offers a precise portrayal of all the members' roles. The application interacts with the blockchain network, which is built using IPFS. This paper will help in providing a secure and decentralized system for the land registry process. The proposed consensus algorithm MRRCM achieves less time required to generated a block on an average by 3.06% round-robin and 96.48% PoW approach. The proposed modified hash table search approach requires less time to search the blockchain's land record block than the extensive liner searches and hash table search approach. A search for a land record in the blockchain reduces the search time on an average by 59.5% compared to the traditional extensive liner search approach and by 18.68% as compared with the hash table search approach.
No-Regret Matching Game Algorithm for NOMA Based UAV-Assisted NB-IoT Systems
Authors: Metwaly Samar Shaker , El-Haleem Ahmed. M. Abd , El-Ghandour Osama
Published: April 2021

NB-IoT is the standardized technology for machine type communication (MTC) in Long Term Evolution (LTE). NB-IoT can achieve IoT requirements nevertheless, it suffers a low rate and capacity. On the other hand, Unmanned aerial vehicles (UAV) and Non-Orthogonal Multiple Access (NOMA) are promising technology used to enhance the throughput, capacity, and coverage of wireless communication networks. In this paper, we propose a heterogeneous network scenario where a UAV small Base Station (UBS) is used to assist the LTE Macro Base Station (MBS) with the help of the Non-Orthogonal Multiple Access technique to solve the NB-IoT throughput and capacity issues. Matching game based no-regret learning algorithm is proposed to optimize the NB-IoT device association and using NOMA pairing at each base station to provide the maximum system total rate and capacity. Simulation results show that our proposed scheme increases the total rate of the system by 60% and the system capacity by at least 80%, compared to NOMA without UAV and the total rate and capacity of the system by 200% and 85% respectively, with OMA scheme.
An Enhanced Bankruptcy Prediction Model Using Fuzzy Clustering Model and Random Forest Algorithm
Authors: Saladi Sarojini Devi , Yarlagadda Radhika
Published: April 2021

The rapid advancements made in Information Technologies (IT) have evolved in the prediction model for financial data. Research in the prediction of bankruptcy is inclining to owe to the growth of related associations with economic and social phenomena. Financial crises in recent scenarios have influenced the growth of financial institutions. Hence, the need for bankruptcy risk prediction at an earlier stage is of prime importance. Though several prediction algorithms were suggested, the predictive models' accuracy is still a challenging task. In this paper, a bankruptcy prediction model is developed by integrating the Fuzzy clustering model and Multi-objective random forest classifiers. The voluminous number of records of the financial dataset and polish bankruptcy dataset is collected from a public repository. It is pre-processed using a MapReduce technique, one of the Big Data approaches. Benefits given by big data approaches help to achieve better flexibility towards a variable declaration. The collected records are pre-processed and organized under efficient index construction. FCM is employed to cluster the data for analytic purposes. Finally, a multi-objective Random Forest classifier helps to develop a prediction model for bankruptcy. Experimental analysis is carried out with accuracy, precision, sensitivity, and specificity compared with existing, Genetic algorithms. Compared to the existing technique, the proposed technique has obtained 80% accuracy.
Correlation between Central Corneal Thickness Corrected Intraocular Pressure with Systolic Hypertension in Adults Over 40 Years in a Tertiary Eye Care Centre
Authors: Jain Pragti , Minj Anita , Mahapatra Ramesh Chandra
Published: April 2021

BACKGROUND Glaucoma is a chronic, progressive optic neuropathy leading to irreversible blindness. Raised intraocular pressure is one of the modifiable risk factors of developing glaucoma. Regulation of intraocular pressure (IOP) is influenced by various factors and, systolic hypertension is one of them. The objectives of the study was to assess the relationship between systolic hypertension and IOP, also to see the effect of controlled and uncontrolled systolic blood pressure (SBP) on IOP in adults above 40 years of age. METHODS This study included a total of 230 known systemic hypertensive patients of age above 40 years. All the patients underwent detailed history taking, careful systemic and ocular examination. IOP was measured by Goldmann applanation tonometer, central corneal thickness (CCT) by anterior segment optical coherence tomography (OCT) and blood pressure (BP) was recorded after 5 minutes of rest. The data was recorded. RESULTS Correlation coefficient for SBP and IOP in right eye (RE) was 0.290 and for left eye (LE) was 0.354 with a probability value of P < 0.0001 which was statistically highly significant. Mean IOP for controlled SBP was 17.76 mmHg in both eyes (BE) which increased to 20.19 mmHg in RE and 20.64 mmHg in LE in uncontrolled SBP. The Z score value between controlled and uncontrolled systolic hypertensive patients in RE and LE was 6.11 and 7.06 respectively (P < 0.0001). There was an increment of IOP for every 10 mmHg in SBP by 0.56 mmHg in right eye and 0.73 mmHg in left eye. CONCLUSIONS Systolic blood pressure is significantly correlated with IOP. The uncontrolled SBP was related to higher mean IOP and mean IOP was found to increase with rise in SBP. Therefore, patients with known hypertension and glaucoma have to be regularly followed-up and should keep their BP in normal range to prevent disease progression.

Analyzing Internet platforms used for publishing and discussing scientific research, subjecting the structural model of a scientific text to theoretical rethinking, the authors demonstrate the importance of alternative ways of expressing scientific ideas, speak of the possibility of a broader interpretation of the concept of “academic writing”. Recent studies have shown that blogging and twittering can serve as a tool to integrate into the academic community and build academic reputation. The authors propose to get away from the formalist interpretation of the genre of scientific text, present academic writing as a continuing dialogue, demonstrate that its genre structure is always open for modifications.
POETICS OF THE TITLE OF JOHN BANVILLE’S NOVEL “THE NEWTON LETTER”
Authors: Gorodetskiy Vladislav P.
Published: April 2021

The article examines the poetics of the title of John Banville’s novella “The NewtonLetter” (1982). There is a fundamental difference between this text and other novels included in the “scientific trilogy” of the writer, dedicated to the great geniuses of science: elements of a selfreflexive narrative, an introduction of an unreliable narrator-biographer, a departure from the main plot of the biography of the scientist). “The Newton Letter” appears as a postmodernist embodiment of epistemological and ontological doubt, a detailed self-reflection about the crisis of narration and nomination. The very act of writing a letter in its personal dimension emphasizes Banville’s recognition of the incomprehensible complexity of the orders of the universe, the chaotic mundane experience, the strangeness of human relations, and the impenetrability of the consciousness of the Other, as opposed to well-reasoned scientific report. The figures associated with the plot of the creative crisis are the narratorBanville; the narrator-Newton; Newton-Chandos; at different textual levels they all are expressing a deep language skepticism in the form of a letter.

O concreto é considerado um dos materiais mais utilizados do mundo, com inúmeras aplicações na construção civil. Apesar disso ainda apresenta deficiências que necessitam ser supridas e atendidas. Devido a isso, diversos materiais têm sido a ele incorporados para interferir em suas propriedades, como por exemplo, seu comportamento após fissuração.   Fibras as mais diversas têm sido usadas e aqui procurou-se estudar como se comporta o concreto reforçado com fibras de bambu (CRFB).  O presente trabalho intenta mostrar a importância de materiais alternativos na construção civil, com enfoque nas fibras de bambu.  São avaliadas as resistências à compressão simples, à tração na flexão e por compressão diametral de concretos produzidos em laboratórios, com teores em peso de 0%, 0,5% e 1,0% de fibras. Os resultados indicam que o acréscimo no teor de fibras diminui a trabalhabilidade, bem como a facilidade de aplicação e de adensamento do concreto; no estado endurecido não houve alteração significativa na resistência à compressão aos 28 dias, porém pequeno decréscimo para idade de 63 dias; nos ensaios de resistência à tração as fibras mostraram boa interação com a matriz cimentícia.

Published: April 2021

The study focuses on the comparison of the chemical and mineral composition of Lunar regolith probes from Luna-16, -20, -24 stations and their the sea-continent environments. Using microprobe JXA-8200 and JSM-5610LV (400 analyses, 50 images, 9 fragments of layer-by-layer core samples) 18 mineral phases and their 12 varieties were diagnosed. The most common are iron-magnesium and calcium-bearing varieties of silicates – anortite, clinopyroxenes and olivine. The typomorphic features of rock-forming minerals in two types of the lunar surface are discussed. The composition of chromespinelids is demonstrated on a triangular prism diagram.

Published: April 2021

A model problem of the permeability field identification for a three-dimensional reservoir opened by a large number of wells in the conditions of stationary single-phase fluid filtration is considered. The permeability field is determined in the process of solving the inverse coefficient problem by on known values of bottomhole pressure. The solving problem algorithm is constructed so that the proportionality coefficients of the layers permeability on wells obtained from the results of geophysical well survey are preserved. The influence of various types of errors on the identification results is studied.

Authors: Gaydukov Leonid A.
Published: April 2021

A laboratory and numerical study of the mechanisms that affect the structure and physical properties of the borehole zone of a production well at various stages of development of a saline formation with textural wettability was conducted. It is shown that for the object of study is characterized by the formation of complex borehole vicinity of the structure and dynamic change of properties which define the specific geotechnical effects: desalinization; pinched adscititious water in the pore space; the decompression and the strain on the washed areas; precipitation of solid salt sediment at the moment of breaking through the highly mineralized front of the injected water. The synergetic effect of these effects leads to the formation of complex, including non-monotonic, permeability distribution profiles in the near-well zone.

Two express methods are presented in this paper. The first method is a high-resolution gamma-spectroscopic method based on a germanium detector, the second method is an IR-spectroscopic method. The applied complex of methods allows to determine the sources of uranium and thorium, identify the rhythms of uranium accumulation associated with regional events; identify areas with a high content of uranium due to the influence of local sources (faults, hydrothermal, etc.); determine the amount of authigenous uranium in the composition of total uranium; determine thermal maturity of organic matter in shales without their preliminary demineralization. To identify levels of increased uranium intensity in the high-carbon strata, a set of indicators has been proposed, which includes both applied indicators in practice of geological work and new indicators.
New indicators have been tested on the collection of shale reference samples. For them, values ​​were established that characterize the processes of uranium accumulation and uranium removal. On the example of Ukhta Region according to the proposed indicators, the sections from the Vendian-Riphean to Domanic inclusive were interpreted.
The performed work showed the possibility of comparing the calculated gamma-spectroscopic data with the data of other methods. This opens up a broader perspective for the use of express non-destructive gamma-spectroscopic method for detecting levels with a high content of uranium in the shale rocks, to which ore-bearing concentrations of a number of metals are also confined.

The article considers the geochemical characteristics of the rocks of the Bazhenov and Nizhnetutleim formations in the southwestern part of the West Siberian oil and gas province, or rather in the territory of the Karabash search zone. The work was carried out on the basis of the core material study of the section of 29 wells within the Karabash zone by pyrolysis on the Rock-Eval 6. The regularities of the distribution of organic carbon concentrations (Сorg, %) on the studied territory were obtained. With the help of data mapping, it was established that the maximum concentrations of organic matter are timed to the southern regions of the zone (the most submerged parts of the paleobasin). The assessment of the catagenesis degree (degree of maturity) of organic matter of the Bazhenov horizon in the study area was carried out. Level maturity of organic matter of rocks is specified in the parameter Tmax Rock-Eval. Within the study area it’s increasing from South to North, from graduation PK3 (according to the scale of N.B. Vassoevich) (Tmax < 430 0С) in the area of wells Verkhnetyumskaya 34 to MK2 (Tmax 440–445 0С) in the area of Molodezhnaya and the Zapadno-Frolovskaya square. The resulting catagenetic zoning determined the boundaries of the generation kitchen for this territory. Generation scale for the Upper Jurassic source rocks was estimated, taking into account its lithofacial structure.
A novel bileaflet sparing technique during mitral valve replacement: Lafci’s fold down technique
Authors: LAFÇI Gökhan
Published: April 2021

Sub-valvular apparatus preservation procedure is an additional technique to mitral valve replacement which decrease the prevalence of low cardiac output syndrome and associated complications that may be seen after mitral valve replacement. A number of surgical techniques for both bileaflet and posterior leaflet preservation have been described previously. We aimed to share how we do the bileaflet preservation with a modified technique, Lafci’s anterior leaflet fold down technique, in selected patients who underwent mitral valve replacement procedure.With absence of resection and use of same sutures for both sparing leaflet and fixing mechanical valve may shorten cross-clamping time, and so, we believe that this technique is simple, reproducible when it is appropriate for the patient’s existing anatomy.

In industrial practice, rock hydration inhibitors, classified as amine compounds, are being increasingly used in drilling mud compositions. There is no methodology for determining this type of compounds content in the drilling mud, and proper servicing of this type of muds requires constant monitoring of their content to ensure appropriate inhibitory properties. During drilling, amine compounds adsorb on the surface of rocks and their concentration decreases during drilling and reduces the inhibitory properties of the mud. A common additive used in the composition of drilling muds is latex, the determination of which is necessary to ensure the mud parameters stability. Compounds of this type ensure the stability of the borehole wall, while their content also decreases during drilling. The results obtained from the research presented in the article allowed to propose methods for the determination of amine compounds and latexes. These methods can be used in the field laboratory when servicing drilling muds. The article presents the methodology for determining the content of new types of chemicals used in drilling muds, i.e. rock hydration inhibitors classified as amine compounds and latexes. The proposed methods enable proper servicing of muds with the addition of the agents that ensure the maintenance of appropriate mud properties. The method for the determination of amine compounds consists in determining the total nitrogen in the drilling mud filtrate. Dilution of the filtrate provides the results within the measuring range of the method and reduces the concentration of chloride ions, the amount of which may not exceed 10 000 mg/dm3. The first method of latex determination is weight determination of the dry residue after separation of the latex from the filtrate with acetone. The second one is based on nephelometric measurements of a tenfold diluted filtrate. The measurement result is the NTU (nephelometric turbidity unit) value depending on the latex content in the filtrate. All of the developed methods require the preparation of calibration curves, which are the basis for calculating the content of a given agent in the mud.
