Вербализация концепта «Россия» в российском политическом дискурсе
Authors:   Uniwersytet w Białymstoku. Wydział Filologiczny. Katedra Językoznawstwa Slawistycznego, Szymula Robert
Published: January 2022

The article is devoted to the analysis of the concept of “Russia”, which is characteristic for Russian political discourse, and the ways it is verbalized in the official programs of political parties. The study material covered the election programs of the 11 biggest Russian political parties, published on their official websites. The study included an analysis of lexical units used to realize the concept of “Russia” and the expressions associated with them. It was found that the verbalization of this concept is realized by means of an array of different lexical units, neutral and those carrying an emotional load, which may invoke in voters positive connotations related to patriotic feelings and a sense of pride. Such lexemes are accompanied by a number of different expressions which serve the integrative function, emphasize the significance of Russia among other countries and its great future, and refer to basic values and the basic psychological needs of inhabitants of the country
„Szloma Korkociąg przed sądem”, czyli humor na łamach tygodnika „Pod Pręgierz”
Authors:   Uniwersytet Warszawski. Wydział Polonistyki. Instytut Polonistyki Stosowanej, Wojtyńska-Nowotka Milena
Published: January 2022

The subject of the article is a series of humorous works “Szloma Korkociąg przed sądem”, which was published in the anti-Semitic weekly “Pod Pręgierz”. The author focuses on describing the linguistic comedy, the means of which was the stylization of the Polish language for Jews. She also draws attention to situational comedy. The results of the analysis showed that contrast was the essence of the comedy in the pages of selected works. It reflected the dichotomous vision of the world presented by the sender and recipient of the texts; a world in which Poles of Jewish origin were negatively evaluated. The presented comic texts, by spreading anti-Semitism, and harming representatives of the ethnic minority, are part of the phenomenon of linguistic aggression.
Binary PSO Variants for Feature Selection in Handwritten Signature Authentication
Authors: Hancer Emrah , Bardamova Marina , Hodashinsky Ilya , Sarin Konstantin , Slezkin Artem , Svetlakov Mikhail
Published: January 2022

In this paper we propose modifications of the well-known algorithm of particle swarm optimization (PSO). These changes affect the mapping of the motion of particles from continuous space to binary space for searching in it, which is widely used to solve the problem of feature selection. The modified binary PSO variations were tested on the dataset SVC2004 dedicated to the problem of user authentication based on dynamic features of a handwritten signature. In the example of k-nearest neighbours (kNN), experiments were carried out to find the optimal subset of features. The search for the subset was considered as a multicriteria optimization problem, taking into account the accuracy of the model and the number of features.

The Trypillia settlement is located at the western edge of Hlybochok village (former Zvenyhorodka district of Cherkasy Oblast), at the plateau of the western bank of the Hirskyi Tikych River. According to the geophysical surveys, the settlement size reached 100 ha. Its dwellings were organized into two ellipses. The remains of two dwellings (ploshchadki) were excavated in 1994—1995. Ploshchadka No. 1 was located in the southern part of the external construction ellipse, while ploshchadka No. 2 was located in the second internal ellipse at the eastern part of the site. The remains of both houses had a rectangular shape and included several layers of burnt clay. Houses had fireplaces on the lower storey. The second house also included an elevation of rectangular shape with grinding stones. Living areas are associated with the upper storey of houses. The majority of materials, mainly kitchen and table pottery, were found between the layers of burnt clay. Kitchen pottery (6—7 %) is represented by conical bowls and pots with S-shaped profiles with poor ornamentation. Table pottery (92—93 %) is represented by ceramics ornamented with black monochromic painting. Nearly 45 % of pottery forms and 25 % of ornamentation schemes were reconstructed. Ceramic shapes are represented by bowls, goblets, biconical, spherical and conical vessels, amphorae, pear-shaped vessels, leads, craters, pots and binocular-shaped vessels. Anthropomorphic figurines were found in fragments. The Hlybochok settlement is referred to the late phase of Nebelivska group (the end of BII period) of the development of the Western Trypillia culture. The settlement is dated to the range of 3925—3825 BC. The Nebelivska group marks the migration of the Western Trypillia culture populations to the north-eastern direction, towards the Middle Dnieper region. Its further development between the Ros and the Dnieper rivers resulted in the formation of Kanivska local group, which pottery is also characterized by the influence of the Eastern Trypillia traditions. In the indigenous area the Nebelivska local group was replaced by the Tomashivska group.
The History of Excavations in the Crimea in 1920-1930's in the Letters to Mykola Ernst
Authors:   PhD in History, Leading Researcher, The National Museum of the History of Ukraine, Popelnytska Olena
Published: January 2022

The Scientific Archive of the National Museum of the History of Ukraine (NA NMIU) contains three letters dated by 07/15/1930, 09/15/1930 and 11/30/1935, addressed to the famous archaelogist of the Crimea Nikolai Ernst (1889—1956), the authors of which are famous archaeologists Boris Zhukov, Lavrenty Moiseev and Petr Efimenko. These letters contain information about excavations, which in 1920’s — 1930’s were carried out in different regions of the Crimean peninsula and are important sources for studying the history of the Crimean archaeological study. Today N. Ernst’s documents, stored in the archives of Simferopol, Kyiv, St. Petersburg and Moscow, are used by researchers who study the archaeological heritage and life of N. Ernst. However, three letters from the NA NMIU have not become the subject of a separate study yet and have not been introduced into scientific circulation. The addressee of these letters, N. Ernst, in 1920’s, worked in the Crimean department for museums and protection of monuments of art and antiquity, was the secretary of the Taurida Society of History, Archaeology and Ethnography, and in April 1930 he headed this Society. These letters contain information about archaeological research in the Crimea, which is not mentioned in the published article by N. Ernst ‘Chronicle of archaeological excavations and exploration in the Crimea for 10 years (1921—1930)’. The letters of B. Zhukov (1930) and L. Moiseev (1930) are probably the answers to the request of N. Ernst, as the head of the Taurida Society of History, Archaeology and Ethnography, send information about the work of local archaeological expeditions for the preparation of a general report. These letters contain information about excavations of archaeological monuments from different historical eras, which are located in different regions of the Crimea and are an important source on the history of the Crimean archaeology of 1920’s — 1930’s. In the third letter, the author of which is P. Efimenko (1935), talks about the participation of N. Ernst in the meeting of the Commission for the Study of Fossil Man, which took place in Leningrad on 20—25th December 1935. The purpose of this meeting was to prepare the Soviet section of INQUA to participate in September 1936 in the III International Conference of the Association for the Study of the Quaternary. Efimenko recommended N. Ernst to prepare a report on the results of the exploration of the Chokurcha Cave.

Authors: Vieira Serra Flávia Cristina , Almeida Jr. Eduardo Bezerra de
Published: January 2022

Introduction: The “restingas” (coast vegetation) can serve as a species corridor in ecotonal environments due to the particulars regarding the composition of the flora. The studies covering the entire length of the Maranhão state coast are necessary to understand the diversity and distribution of plant species present in the “restingas”. Objective: The objective of this study was to characterize the structure and conservation of the woody vegetation of a “restinga” in Maranhão. Methods: Phytosociological sampling of woody vegetation was carried out using the quadrants method, followed by classification of species by successional group; in addition to analyzing the diametric and hypsometric data of the populations whose species presented the highest importance value (IV). Results: In total, 24 species and 16 families were identified, 72 % of which were classified in the initial stages of succession. The values of H' and J' were 2.637 nat.ind-1and 0.830, respectively. The mean height and diameter were 2.1 m and 27.66 cm, respectively. The species Coccoloba ramosissima Wedd., Byrsonima crassifolia (L.) Kunth, Anacardium occidentale L., Manilkara triflora (Allemão) Monach, and Astrocaryum vulgare Mart. presented the highest IVs. Conclusions: It was observed that characteristics such as size, power of regrowth, and ease of regeneration processes could be useful for choosing target species for recovery actions in coastal areas.

Published: January 2022

Introduction: Spondias tuberosa is a tree endemic to the semiarid region of Brazil with fruticulture potential. Objective: To estimate the diversity and genetic structure of S. tuberosa accessions from four areas of the semiarid region of Brazil, in order to facilitate conservation genetic resources studies in this species. Methods: DNA was extracted, using the CTAB 2x method, from leaf samples of 24 accessions of S. tuberosa available in the germplasm bank at Embrapa Semiárido, Brazil. Ten microsatellite loci were used in this study. Results: The UPGMA dendrogram, generated with a Jaccard coefficient similarity matrix, contains four groups at a 0.44 cutoff point. The similarity coefficient ranged from 0.30 to 0.84, indicating great divergence among the accessions. A Bayesian analysis conducted with the software Structure suggests there are two subpopulations, one formed by accessions from the Januária region and another by accessions from the Juazeiro, Uauá and Petrolina regions. The ΦST value of 0.12 for the analysis of molecular variance indicates moderate genetic differentiation among the four populations, suggesting that the genetic variability is moderately structured in function of region. Conclusions: Together, the analyses indicate that the genetic diversity of S. tuberosa is not uniformly distributed in the studied regions. Thus, germplasm from a greater number of populations should be collected to increase the germplasm bank genetic diversity of the species.
Consumo de embutidos en mujeres costarricenses: efecto del nivel socioeconómico
Authors: Santamaría-Ulloa Carolina , Bekelman Traci A.
Published: January 2022

Introducción: El consumo de embutidos se ha asociado con serios problemas de salud que son comunes entre la población femenina. En el 2015 la Agencia Internacional para la Investigación en Cáncer clasificó los embutidos, como carcinógenos para los seres humanos ya que su ingesta está relacionada con el cáncer colorrectal. El aumento en el consumo de embutidos, los cuales son un alimento fuente de proteína de bajo costo, es diferencial según nivel socioeconómico y puede tener un impacto en la incidencia de enfermedades crónicas en la población. Objetivo: examinar la asociación entre el consumo de embutidos y (a) la ingesta total de proteína, (b) la ingesta inadecuada de proteína, según NSE. Métodos: Se seleccionó una muestra (N = 135) de mujeres de 25 a 45 años, con 1 a 4 hijos, pertenecientes a tres diferentes niveles socioeconómicos, residentes de dos cantones del Gran Área Metropolitana de San José, Costa Rica, entre junio 2014 y marzo 2015. Mediante el uso de fotografías se indagó la percepción de las mujeres en cuanto al costo y su preferencia de consumo de 12 distintos alimentos, entre los cuales se incluyó los embutidos. Por medio de recordatorios alimentarios de 24 horas recolectados en tres visitas diferentes, y el uso de la base de datos de composición de alimentos ValorNut, se midió el consumo de proteína total en gramos y se determinó la cantidad promedio de veces por día que las mujeres consumen embutidos. A partir del peso de cada participante se determinó su requerimiento de proteína. La ingesta inadecuada de proteína se estimó como la diferencia entre el requerimiento y la ingesta observada. Mediante un modelo de regresión lineal se determinó la asociación entre el consumo total de proteína medido en gramos y la cantidad de veces por día que se ingiere embutidos. Mediante un modelo de regresión logística se estimó la asociación entre la ingesta inadecuada de proteína y la cantidad de veces por día que se ingiere embutidos. Resultados: Los embutidos son percibidos como la fuente de proteína menos apetecible, sin embargo, fue la tercera fuente de proteína más consumida. El consumo de embutidos difiere según NSE (P < 0.01), en el alto NSE es donde se consumen con menor frecuencia. Los embutidos más comúnmente consumidos fueron mortadela (bajo NSE), salchichón (NSE medio), y jamón de pavo (alto NSE). El consumo de embutidos se asocia significativamente con un incremento en la ingesta de proteína. Se encontró una asociación inversa entre el NSE y la ingesta inadecuada de proteína. Conclusiones: El consumo de embutidos está asociado con el nivel socioeconómico. Es probable que las mujeres consuman embutidos porque los perciben como un alimento fuente de proteína de bajo costo. Se requiere establecer estrategias educativas que ayuden a las mujeres a identificar sus necesidades alimentarias de proteína y a conciliar estas necesidades con la adquisición de alimentos saludables a un costo aceptable.

Authors: Angelova T. , Krastanov J. , Yordanova D.
Published: January 2022

Abstract. The aim of the present study was to evaluate allele frequencies and genotypes of kappa casein (CSN3) and their association with milk quality and coagulation properties in Brown cattle. Milk proteins’ polymorphism was found out in 155 tissue samples from cows reared at 4 farms. The analysis of milk composition was done in the lab of the Agriculture Institute – Stara Zagora on Lactoscan ultrasound milk analyzer, whereas coagulation properties of individual milk samples were evaluated on a Computerized Renneting Metter – Polo Trade, Italy. Milk samples were obtained by milk meters. The milk was analysed within 3 hours after sample collection. Naturen Plus 215/0.8L chymosin was used, with milk coagulation activity of 215 IMCU/ml. During the study, the following parameters were studied: milk fat and protein contents (%), rennet coagulation time (RCT, min), curd firmness (а30, mm) and curd firming time (k20, min). Kappa casein (CSN3) is characterised by five genotypes – АА, АВ, ВВ, АН and ВН, the frequency of which varied within various ranges. The milk of cows with genotype AB was characterized by the highest content of fat and protein: 4.85% and 5.00%, respectively. The milk of heterozygous cows from genotype AB demonstrated the longest rennet coagulation time – 18.04 min. The animals carrying the H allele produced milk with the highest curd firmness – 37.00 mm.
True digestibility of the essential amino acids of high-protein sunflower meals by balanced experiments with intact and caecectomized birds from Gallus species
Authors: Chobanova S. , Penkov D.
Published: January 2022

Abstract. Using adapted methods for balanced experiments with poultry, the true digestibility coefficients of the essential amino acids of two high protein sunflower meals – 40+® and 47® have been established. The true digestibility coefficients by using two methods – with intact and randomized (caecectomized) birds have been compared. Six birds were tube fed and six – feed deprived for both of the fodders. The amino acids were established with amino analyzer AAA-881 after preliminary HCl hydrolysis. The mean digestibility of sunflower meal 40+® is higher in intact (88.11 versus 85.73 of sunflower meal 47®) compared to randomized birds (87.20 versus 85.46 of sunflower meal 47®). The differences by lots are statistically significant only in intact birds. The authors recommend for practical needs to use the average true digestibility coefficients between both meals, established with randomized birds (ileal digestibility).

Authors: Suhiel Ibrahim Alaa
Published: January 2022

Abstract. The world has always been striving to increase and intensify agricultural production, and there are several attempts to acheive that, such as grafting tomato on potato to obtain two crops from one plant. This investigation was conducted during 2020 in open field in Nahl village, Baniyas, Tartous Governorate, Syria. The vegetative and generative growth and yield have been studied for pomato (grafted tomato on potato) and compared to each tomato and potato separately. Tomato plants were significantly superior in plant height to pomato plants after 23 days of planting until the end of the experiment. On the other hand, there were significant differences between tomato plants and pomato plants in the leaf area after 23, 51 and 65 days of planting. Also, tomato plants significantly outperformed pomato plants in the number of flowers and fruits per plant and the tomato fruit set percent. Anyway, tomato plants were significantly superior in the average yield of tomato fruits per plant (1657 g.plant-1) to pomato plants (185 g.plant-1), while there were insignificant differences in the average yield of potato tubers per plant between pomato which failed to produce tubers and potato (48.25 g.plant-1). Studying the tomato fruit fresh weight showed a significant superiority of tomato plants (54.37 g.fruit-1) to pomato plants (35.97 g.fruit-1), while there were insignificant differences in the other physical (tomato fruit height, diameter and shape index) and chemical (tomato fruit content of total acids, total soluble solids and dry matter, %) properties.
Efficacy of local Bacillus thuringiensis isolates against tomato leaf miner (Tuta absoluta) larvae on tomato plants under screenhouse conditions
Authors: Akinyelure E.O. , Machido D.A. , Atta H.I.
Published: January 2022

Abstract. The negative impact of chemical pesticides on the environment and the increased resistance of tomato leafminer (Tuta absoluta) field populations to chemical pesticides have promoted research on alternative control measures. Biological control with Bacillus thuringiensis (Bt) may be an alternative, especially against larval instars of T. absoluta. A total of five B. thuringiensis strains were isolated from soil sampled from two different Cow range lands in Zaria, Nigeria; and they were screened for the presence of the cry1 genes using polymerase chain reaction. Of the five isolates, two (40%) showed the presence of the cry1 genes. Results of the bioassay conducted against 2nd instar larvae of T. absoluta at 28±2°C indicated that each of the concentrations (25, 50, 75 and 100 ppm) of the spore crystal mixtures derived from the isolates harbouring cry1 genes caused significant mortality to larvae of T. absoluta after 72 hours in comparison to the control (0 ppm). Probit analysis was used to determine the LC50 and LT50 values. When the treatments were assessed at 48 and 72 hours, LC50 values against larvae were 74.1 and 25.3 ppm for isolate F3, while the LT50 values of that same isolate F3 at 100 ppm and 75 ppm were 36.3 and 42.7 hours, respectively. B. thuringiensis strain F2 achieved 68.7% reduction in T. absoluta damage on tomato plants, while B. thuringiensis isolate F3 achieved 71.3% reduction. Therefore, the spore crystal mixture derived from indigenous Bt strains is the candidate to be used for foliar application against T. absoluta and it is recommended into integrated pest control strategies for the management of T. absoluta.

Published: January 2022

Abstract. The aim of the study was to determine the dependence between Test Day (TD) milk productivity traits and somatic cells count (SCC) in milk and also the influence of the factors: farm, parity and TD recording season of Holstein cows. The survey included a total of 484 lactating cows from 8 cattle farms in Bulgaria. A total of 3473 TD records including data on TD milk yield, fat %, protein % and SCC in milk were used. A statistically significant effect of the farm, recording season, and SCC on TD milk yield, fat % and protein % was reported. The highest TD milk yield was reported in spring (22.42 kg), followed by winter (21.95 kg). In winter and autumn were reported higher mean values for TD fat (3.77 and 3.84%) and TD protein (3.38 and 3.40%) content in milk. At the highest SCC – above 999 000 cells/ml, the highest average daily milk yield – 24.1 kg and the lowest fat (3.48%) was reported. With the highest and positive statistically significant value was the phenotypic correlation between TD milk yield and SCC (0.21). The correlation with TD fat % was statistically significant, with negative value (- 0.07).

Published: January 2022

The COVID-19 pandemic has led to significant global health and economic consequences. There is an unmet need to define a molecular fingerprint of severity of the disease that may guide an early, rational and directed intervention preventing severe illness. We collected plasma from patients with moderate (nine cases), severe (22 cases) and critical (five cases) COVID-19 within three days of hospitalization (approximately one week after symptom onset) and used a cytokine antibody array to screen the 105 cytokines included in the array. We found that I-TAC, IP-10, ST2 and IL-1ra were significantly upregulated in patients with critical disease as compared to the non-critical (moderate and severe combined). ELISA further quantified I-TAC levels as 590.24±410.89, 645.35±517.59 and 1613.53±1010.59 pg/ml in moderate, severe and critical groups, respectively. Statistical analysis showed that I-TAC levels were significantly higher in patients with critical disease when compared with moderate (p = 0.04), severe (p = 0.03) or the combined non-critical (p = 0.02) group. Although limited by the low sample numbers, this study may suggest a role of I-TAC as a potential early marker to discriminate between critical and non-critical COVID-19 cases. Such knowledge is urgently needed for appropriate allocation of resources and to serve as a platform for future research towards early interventions that could mitigate disease severity and save lives.

DIFFERENTIAL GAME WITH A LIFELINE FOR THE INERTIAL MOVEMENTS OF PLAYERS
Authors: Samatov Bahrom T. , Soyibboev Ulmasjon B.
Published: January 2022

In this paper, we study the well-known problem of Isaacs called the "Life line" game when movements of players occur by acceleration vectors, that is, by inertia in Euclidean space. To solve this problem, we investigate the dynamics of the attainability domain of an evader through finding solvability conditions of the pursuit-evasion problems in favor of a pursuer or an evader. Here a pursuit problem is solved by a parallel pursuit strategy. To solve an evasion problem, we propose a strategy for the evader and show that the evasion is possible from given initial positions of players. Note that this work develops and continues studies of Isaacs, Petrosjan, Pshenichnii, Azamov, and others performed for the case of players' movements without inertia.

Resistance training exercise selection: efficiency, safety and comfort analysis method
Authors: Bezerra Ewertton de Souza , Schoenfeld Brad J. , Orssatto Lucas Bet da Rosa , Mayhew Jerry L. , Ribeiro Alex Silva
Published: January 2022

Abstract Manipulation of resistance training variables has been shown to have a substantial effect on muscular adaptations. A major variable in this process is exercise selection. In addition to the effectiveness of a given exercise to recruit the target muscle groups, safety considerations and individual comfort during execution of a lift should be considered. The correct biomechanics of the chosen exercise will assist in promoting desired muscle adaptations, while proper safety procedures will reduce risk of injury. Lifting comfort will facilitate enjoyment and foster adherence to the program. Therefore, the purpose of this paper was to offer guidelines for selection of resistance training exercises based on the Efficiency, Safety, and Comfort Analysis Method (ESCAM).

Published: January 2022

Resumo Neste artigo apresenta-se um estudo sobre construção de escalas, com base na Teoria da Resposta ao Item (TRI), para medir proficiência em conteúdos matemáticos básicos, necessários ao acompanhamento das disciplinas de Cálculo e similares, de ingressantes em cursos da área de Ciências Exatas. Adotou-se o modelo logístico unidimensional de três parâmetros, que estabelece média zero e desvio padrão 1, para as proficiências dos indivíduos. As proficiências estimadas foram transformadas em outra escala, optando-se por valores adotados por sistemas de avaliação brasileiros, a saber, 250 e 50. O instrumento de medida consistiu em uma prova com 36 itens, de cinco alternativas, somente uma correta, elaborados com base em uma matriz de referência, dividida em três temas, “Espaço e Forma”, “Grandezas e Medidas” e “Números e Operações, Álgebra e Funções”. Cada tema é composto por competências, que descrevem as habilidades que se deseja medir. Para a construção da escala foram especificados níveis de proficiência, representando pontos selecionados pelos pesquisadores para serem interpretados pedagogicamente. Estabelecidos os níveis âncora, foram definidos os itens âncora, a partir de critérios, como, por exemplo, o número de acertos, os percentuais de acertos e a diferença entre seus valores, para níveis consecutivos. Com base nestes critérios, comparou-se três métodos de posicionamento dos itens, mostrando as dificuldades de interpretação em pontos da escala. Tais dificuldades oportunizaram a propositura de outro método, segmentando a escala em faixas de proficiência, com base em agrupamentos hierárquicos dos níveis, o que permitiu a interpretação da escala em toda a sua amplitude.
Sobre as etnocracias das ajudas humanitárias no Líbano
Authors: Carpi Estella
Published: January 2022

Resumo Neste artigo, discuto a tendência do sistema humanitário de fornecer serviços às pessoas necessitadas em áreas afetadas pela crise baseando-se na nacionalidade. Através de dados coletados em pesquisas de campo com refugiados sírios, iraquianos, sudaneses e palestinos realizadas entre os anos 2011 e 2019 no Líbano, mostrarei como a hospitalidade pode ser empregada tanto como prática quanto como discurso. Neste último caso, explicarei como isso pode se transformar, de maneira problemática, em uma força de “etnização” na prestação de ajuda humanitária. Como resultado, de um uso conservador do discurso da hospitalidade, apresentarei o conceito de “humanitarismo compensatório” que atende aos habitantes locais como uma consequência da presença de refugiados. Contra esse pano de fundo, finalmente mostrarei como o sistema humanitário atual está longe de ser intergrupal, apesar de seus esforços para tornar os programas nacionalmente mistos. Na verdade, o humanitarismo simplesmente propõe programas mistos para, presumivelmente, dissipar as tensões intergrupais, revelando, portanto, uma neo-etnização das ajudas.
El patrocinio de refugiados: una revisión sistemática descriptiva
Authors: Cortés Ana Irene Rovetta
Published: January 2022

Resumen En la última década diecisiete países occidentales han adoptado “esquemas de patrocinio” como respuesta a la denominada “crisis de los refugiados”. La revisión y sistematización de cuarenta y tres textos publicados sobre tales iniciativas permite detectar importantes diferencias en el diseño y alcance de las mismas en cada una de las regiones del mundo en que se han implementado (Norteamérica, Oceanía, Europa y América Latina). Se advierte, asimismo, que son más los autores partidarios de este tipo de propuestas que aquellos que lo cuestionan, ya sea éste una vía privatizada de reasentamiento, un mecanismo de reunificación familiar, un canal de admisión humanitaria y/o, simplemente, un proyecto de acompañamiento lego. A través del análisis se identifican dos principios diferentes al principio de adicionalidad que caracterizó al modelo original de patrocinio canadiense y ello sugiere que las lecturas economicistas y/o humanitarias estarían eclipsando las interpretaciones políticas y centradas en un enfoque de derechos.

ABSTRACT Objective: To evaluate the morphometry of the pelvis to determine the safe trajectory for the insertion of the S2-iliac screw, and to correlate it with studies reported in the literature for other populations. Method: The computed tomography (CT) pelvic exams of 36 Brazilian patients without congenital malformations, tumors, pelvic ring fractures or dysplasias were selected from the database of a radiological clinic. To define the ideal trajectory of the S2-iliac screw, the following variables were measured: 1- maximum sacroiliac screw length; 2- thickness of the iliac dipole for planning the choice of screw dimensions (length and diameter); 3 - distance between the insertion point of the iliac S2 screw and the posterior sacral cortex; 4 - angulation for insertion of the screw in the mediolateral direction, representing the angle formed between the “iliac line” and the anatomical sagittal plane; 5- Angulation for insertion of the screw in the craniocaudal direction. The Pearson's chi squared and student's t tests were used for statistical analysis. Results: The sample consisted of 36 patients, 50% (18/36) of whom were women. The mean age was 63.7 years, ranging from 23 to 96 years. All the pelvic morphometric variables analyzed presented values similar to those described in the literature for other populations. Conclusion: Prior evaluation of the tomography exams was important for preoperative planning, and there was a statistically significant difference between the sexes only in relation to the variables left craniocaudal and length of the left internal table. Level of evidence III; Observational cross-sectional study.
CORRELATION BETWEEN THE MODIC I SIGN AND IMAGES OF VERTEBRAL INSTABILITY
Authors: Bazán Pedro Luis , Borri Álvaro Enrique , Medina Martín
Published: January 2022

ABSTRACT The lumbar region is highly affected by degenerative diseases and can be symptomatic as a result of inflammatory processes of the disc or segmental vertebral instability (SVI), according to concepts by White and Panjabi. Magnetic resonance imaging (MRI) and dynamic radiographs can be used to evaluate it. Objective: To determine whether images of Modic type I lesions are compatible with radiological vertebral instability. Methods: The MRIs and dynamic radiographs of 100 patients with a mean age of 46.94 years, 65 of whom were women and 35 of whom were men, were studied to evaluate the reaction of endplates according to Modic and SVI at levels L2-L3, L3-L4, L4-L5 and L5-S1. They were divided into 3 groups: A- Modic I and SVI; B- Modic I without SVI; and C- Without Modic I and SVI. Sex, age and type of disc were evaluated. Result: 46 Modic I lesions and 24 cases of SVI were recognized. There were 5 patients in Group A (OR 0.23, p=0.006), 38 in Group B; and 19 in Group C. No direct relationship between age and Modic I and/or SVI was observed. Pfirrmann grade 5 discs are 4.6 times more likely to present a Modic I signal. The most affected disc was L3-L4 for the Modic signal and L4-L5 with respect to the SVI, translational instability being more frequent. Conclusions: Modic type changes, identified by magnetic resonance, are clinically relevant in relation to low back pain, but their presence does not confirm either translational or angular instability. Level of evidence III; Cross-sectional cohort.

Published: January 2022

ABSTRACT Objective: To evaluate the peri- and postoperative results and clinical repercussions in patients undergoing decompression surgery and single-level lumbar arthrodesis using the traditional technique (OTLIF) and to compare with the results of minimally invasive techniques (MITLIF) described in the literature. Methods: Our sample consisted of 22 patients who underwent TLIF surgery using the open technique (OTLIF) in the period October 2019 to January 2021, in our hospital. We compared the patients’ functional clinical results using the Oswestry scale in the preoperative period and 15 days after surgery, analyzed variables related to the perioperative period: surgery time, length of hospital stay, blood loss, use of a suction drain, and admission to the ICU, and compared these with the results reported in the literature for patients treated by the MITLIF technique. Results: The average age was 48.95 years and the most operated level was L4-L5 (55%). The average surgery time was 112.63 min. We did not use a suction drain in the postoperative period, there was no need for a blood transfusion in any patient, and no patient was admitted to the ICU. The average hospital stay was 1 day. Regarding the Oswestry Disability Index, the mean preoperative score was 44.73 and after 15 days, it was 24.05. Conclusions: surgical treatment using the OTLIF technique for single-level lumbar degenerative disease showed largely positive results, with improvement in disability scores, short hospital stay and low incidence of complications. When properly indicated, OTLIF is an excellent and safe option for the treatment of degenerative lumbar disease. Level of evidence IV; Case series study.

Abstract Millions of people worldwide, and especially schoolchildren, may be infected by geohelminths due to their exposure to a contaminated environment. The aim of this study was to evaluate soil contamination by Ancylostoma spp. and Toxocara spp. eggs in recreation areas at elementary schools in Pelotas, state of Rio Grande do Sul, Brazil. Sand samples were collected from 22 schools and were processed using the centrifugal flotation method. Helminth eggs with zoonotic potential were found in 12 out of the 22 schools (54.5%). Contamination by Ancylostoma spp. and Toxocara spp. was observed in 36.4% (8/22) and 27.3% (6/22) of the soil samples collected at these schools, respectively. These findings of eggs show that the school communities are exposed to risks of zoonotic transmission.
Assessing and mitigating risks to bridges from large wood using satellite imagery
Authors: Panici Diego , Kripakaran Prakash
Published: January 2022

The transport and accumulation of floating large wood (LW) debris at bridges can pose a major risk to their structural integrity. The impact forces arising from collisions of LW can cause significant damage to piers, while accumulations can constrict the flow and exacerbate scour at piers and abutments. Furthermore, LW accumulations increase afflux upstream of bridges, heightening the flood risk for adjoining areas. There is thus a need for a practical and rapid approach to identify bridges prone to LW-related hazards and prevent the formation of LW accumulations. Based on satellite imagery (SI), an approach is proposed to (a) quantify the risk of LW at a bridge structure and (b) locate a LW-trapping system upstream of the identified vulnerable bridge to dramatically reduce the risks of LW-related damage. The proposed methodology was applied to major rivers in Devon, UK. In this analysis, 26 bridges were identified as at risk to LW, with the majority prone to LW jams. Furthermore, SI was used to identify 12 locations for the potential installation of LW trapping systems for bridge protection. The results of this study show that SI is a powerful tool for the rapid assessment and planning of mitigation measures for bridges at risk to LW.
Simultaneous Joint Lower and Upper record values Probability Laws for Absolutely Continuous or Discrete Data

Published: January 2022

This paper investigates the probability density function (pdf) of the \((2n-1)\)-vector \((n\geq 1)\) of both lower and upper record values for a sequence of independent random variables with common \textit{pdf} \(f\) defined on the same probability space, provided that the lower and upper record times are finite up to \(n\). A lot is known about the lower or the upper record values when they are studied separately. When put together, the challenges are far complicated. The rare results in the literature still present some flaws. This paper begins a new and complete investigation with a few number of records: (n=2\) and \(n=3\). Lessons from these simple cases will allow addressing the general formulation of simultaneous joint lower-upper records.
On Nonparametric Conditional Quantile Estimation for Non-stationary Random

Published: January 2022

A kernel conditional quantile estimate of a real-valued non-stationary spatial process is proposed for a prediction goal at a non-observed location of the underlying process. The originality is based on the ability to take into account some local spatial dependency. Large sample properties based on almost complete and \(L^q\)-consistencies of the estimator are established. A numerical study is given in order to illustrate the performance of our methodology.
