Atividades sobre comparação de área de figuras planas: análise de uma coleção de livros didáticos de matemática do ensino fundamental anos iniciais
Authors: PACHÊCO FRANKLIN FERNANDO FERREIRA , Silva Josinaldo José da , Silva Gustavo Adalberto de França
Published: September 2023

O objetivo da presente pesquisa foi analisar as atividades sobre comparação de áreas de
figuras planas presentes em uma coleção de livros didáticos do ensino fundamental – anos iniciais.
Abordou-se a ideia de área como grandeza autônoma proposta por Douady e Perrin-Glorian. Além
disso, o debate sobre as atividades de comparação de áreas de figuras planas foi apoiado pela ótica de
Baltar. Em termos metodológicos, analisou-se uma coleção de livros didáticos do ensino fundamental
– anos iniciais da disciplina de matemática. Os resultados mostram que existem poucas atividades
sobre comparação de área de figuras planas. Elas, em sua maioria, estão ancoradas em procedimentos
de resoluções numéricas, em especial, o ladrilhamento. Embora as técnicas geométricas (inclusão e
sobreposição, decomposição e recomposição, e equidecomposição) estejam menos presentes, elas são
relevantes por possibilitar a verificação de que as superfícies comparadas podem possuir área maior,
menor ou igual.

Authors: Ferreira Nathália Martins , Ustra Sandro Rogério Vargas
Published: September 2023

A educação financeira é um tema bastante destacado na contemporaneidade, inclusive no
contexto da Educação Básica, enquanto integrante da formação necessária para os desafios da
cidadania plena. Neste trabalho são apresentados resultados da análise de uma coleção de livros
didáticos de matemática dos Anos Finais do Ensino Fundamental, objetivando compreender como os
conteúdos voltados para a educação financeira (EF) são desenvolvidos. Dessa forma, foi utilizada uma
abordagem qualitativa, através da Análise de Conteúdo, na qual foram categorizadas as atividades de
EF que estavam inseridas na coleção “A conquista da Matemática”, uma das mais utilizadas nas
escolas. A análise permitiu identificar importantes características das atividades propostas. Os
conteúdos são apresentados ao final de capítulos em seções que, provavelmente, não serão trabalhadas
pelos professores em sala de aula, uma vez que possuem pouca relação com os conteúdos abordados
no texto principal. Ressente-se de uma reflexão mais aprofundada dos conceitos nas poucas páginas de
cada volume destinadas à EF. Destaca-se a necessidade de esta etapa de escolarização contemplar uma
educação financeira crítica, a qual não significa apenas apresentar os conteúdos, mas também
promover sua articulação a contextos cotidianos, promovendo o exercício da cidadania consciente
quanto ao equilíbrio entre consumo e sustentabilidade, atentando quanto às implicações ambientais em
um mundo globalizado.

Evaluation of CD304 expression in pediatric Blineage acute lymphoblastic leukemia
Authors: Raghda Hameed Jaseem  , Subh Salim Al-Mudallal
Published: September 2023

BACKGROUND: Acute lymphoblastic leukemia is the most common form of cancer (25–30%) and predominant subtype of leukemia (75–80%) in children. However, childhood ALL has considerable phenotypic and genotypic heterogeneity, which is of diagnostic and prognostic importance. CD304 is a transmembrane glycoprotein C-type lectin found on plasmacytoid dendritic cells, It acts as a receptor for class III semaphorins mediating neuronal guidance and axonal growth.Aim of the study: to study expression of CD304 in de novo newly diagnosed pediatric B- lineage ALL patients and to evaluate its association with hematological and clinical parameters.Patients and methods: This cross sectional study was conducted on 30 pediatric patients with de novo newly diagnosed BALL randomly selected in relation to sex included (16 males and 14females) with their age ranging 1-14 year.RESULTS: This study revealed that CD304 was detected in (56.67%) of newly diagnosed B-ALL patients and (43.33%) of them were negative for CD304 expression. It was detected that CD304 was not associated with age, gender, clinical presentations, other prognostic hematological parameters (Hb, WBC count, platelate count), blast percentage, NCI risk, B-ALL subtype, positive PAS and response to induction therapy.CONCLUSIONS: CD304 expression was independent on the hematological and physical characteristics of patients, since the majority of positive CD304B-ALL cases were in high risk groups of NCI criteria and 60% of non- responder were positive CD304. PAS stain was detected in standard risk groups of NCI criteria, common B-ALL subtype and response to induction therapy.

Teaching schoolchildren to work with electronic hypertext in the context of culture-oriented linguistic methodology: the issue and its possible solutions
Authors: Vasilyeva N. V.
Published: September 2023

Modern society is undergoing digitisation that affects the formation of schoolchildren as representatives of Generations Z and Alpha. One feature of such learners is clip or mosaic thinking. Modern science considers rhizomatic thinking as an alternative to clip thinking. Based on the comparison between the electronic hypertext structure and a rhizome, the paper concludes that electronic hypertext is a rhizome. Following rhizomatic thinking researchers, I propose to shape this type of thinking in schoolchildren when working with electronic hypertext. The research has identified the benchmarks for teaching generations Z and Alpha to work with electronic hypertext within the framework of culture-oriented linguistic methodology. The article highlights the significance of students’ learning and research activity in comprehending electronic hypertext as a reflection of the conceptosphere of culture. It has been suggested that the linguocultural concept can be considered as a rhizomatic network «node» or an intersection of meanings transmitted by hypotexts in electronic hypertext. This confirms the potential of studying concepts in the Russian language school course for introducing students to the culture of the people through language.
Common speech mistakes in schoolchildren’s final essays
Authors: Uzdinskaya E. V. , Strukova O. N.
Published: September 2023

It is particularly important to analyse the typical mistakes schoolchildren make in their final essays. This work enables us to identify the gaps in learners’ knowledge resulting in inaccurate expression of thought, violation of logic, and stylistic dissonance. The article considers various typologies of errors obtained from schoolchildren’s essays. We have identified the most common grammatical, lexical, and stylistic errors. The first group includes an incorrect use of aspectual-temporal forms of the verb, participial and adverbial participial phrases, errors in sentences with homogeneous parts, and other issues. Lexically, students tend to choose incorrect words, violate lexical combinability and so on. Stylistic mistakes involve unnecessary use of low colloquial and colloquial vocabulary, literary vocabulary, including officialese, an improper use of figurative and expressive means, and other issues. The paper concludes that schoolchildren’s essays aim to be as literary as possible. Learners use standard constructions, "tried-and-tested" in many works.
E. I. Nikitina’s practical methodology for speech development: traditions and innovations (to the centenary anniversary of the scientist’s birth)
Authors: Levushkina O. N.
Published: September 2023

The article provides a general idea of the formation and evolutionary dynamics of E. I. Nikitina’s methodological system created to develop schoolchildren’s speech. This approach is embodied in the teaching materials and study guides by the scientist-practitioner. The research convincingly proves that the scientist built and methodologically supported a holistic, multi-aspect system for the speech development of schoolchildren from the 1st to the 10th forms. E. I. Nikitina herself called it a practical methodology for speech development. As the main results of the study, this paper gives evidence that the textbooks by E. I. Nikitina, on the one hand, continue the Russian educational traditions of schoolchildren’s speech development. On the other hand, they facilitate those innovations that characterise the modern methodological system of teaching the Russian language. The article shows that E. I. Nikitina’s practical methodology for speech development is particularly notable for the systematic exploitation of the educational potential of Russian language lessons based on working with text. Moreover, her approach provides methodological support for forming students’ communicative competence; it promotes schoolchildren’s speech development in conjunction with the development of their thinking. The methodology is oriented to creative speech development in schoolchildren; it systematically implements problem-based learning techniques which are relevant in the modern educational paradigm, as well as facilitates critical thinking, reflective techniques, and so on.
Specific features of the narrative structure in L. N. Tolstoy’s story "The Forged Coupon" (to the 195th anniversary of the birth)
Authors: Romanov D. A.
Published: September 2023

The subject of the study is "The Forged Coupon", one of the later stories by L. N. Tolstoy. The article considers how Tolstoy’s main discoveries are implemented in the text from the standpoint of constructing a literary narrative. The article presents the novella from the perspective of the writer’s creative mastery evolution. The research employed end-to-end text sampling, semasiological analysis based on lexicographic sources, subtext explication techniques. The study also used psycholinguistic approaches to examine the emotional pattern of the text. The ideological plane of the content is interpreted by identifying key words (heuristemes). The article characterises the dynamics of the narration pace, the nature of the development of the compositional plot lines. It also reveals fragments of a convoluted, compressed narrative and compositional parts based on precedent texts. The study demonstrates L. N. Tolstoy’s techniques for semantic extension of vocabulary and attaching additional connotations to the usual meanings of lexemes. In addition, the paper characterises the forms of syntactic constructions and a special kind of Tolstoy’s tale (or skaz), as well as reveals the semantic charge of foreign inclusions. The research shows the continuity between the mature and late Tolstoy’s style in highlighting a significant artistic detail, embodying the inconsistency of human thinking and emotional states. The article evaluates the influence of the late Tolstoy’s style on the formation of artistic and literary aesthetics of the 20th century.
Lexico-semantic features of V. G. Korolenko’s novella "In Bad Company" (to the 170th anniversary of the birth)
Authors: Shumskikh E. A.
Published: September 2023

The article considers some lexico-semantic features of the novella "In Bad Company" written by Vladimir Galaktionovich Korolenko. The research focuses on such significant lexico-semantic fields as "Life", "Home", "Family" and "Memory" associated with the use of antithesis in the poetics of the work. The article also analyses the meaning of the title of the novella, as well as the antithesis of "decent company" vs "bad company" and determines the role of contrasting the ruins of the count’s castle with the vault of the old Uniate chapel. It is shown that repeated naming is an important means of artistic expressiveness in the novella as it performs various functions (semantic, expressive-stylistic (emotional-expressive), euphemistic, text-forming). The paper also considers some nominative series of repeated naming which are significant for the image composition of Tyburtsy, Marusya, Vasya, and other characters, as well as for the description of the castle ruins, the vault of the old chapel, and so on. The crucial role of lexical repetition and the functions of comparative constructions revealing the protagonist’s personality traits are highlighted. The research methods included linguistic commentary, descriptive method, and semantic-stylistic text interpretation. In some cases, the research used feature (componential) analysis of linguistic units.
Comparative constructions in modern Russian prose: the evolution of figurative comparison
Authors: Nikolina N. A. , Petrova Z. Yu.
Published: September 2023

The research explores the changes undergone by comparative figurative meaning constructions (metaphorical and similative) in modern prose texts in comparison with earlier periods of Russian literature development. The article aims to identify trends in the evolution of comparative constructions in modern Russian prose. The need for a multidimensional description of linguistic processes in modern literary speech determines the relevance of the study. One such process is the evolution of figurative comparison in comparative constructions. We analysed the material of the works by such modern Russian prosaists as Yu. Buyda, V. Zalotukha, Ye. Vodolazkin, A. Ivanov, Z. Prilepin, A. Ilichevsky, T. Kibirov, A. Matveyeva, O. Slavnikova, M. Stepnova, D. Rubina, G. Yakhina and others. Additionally, we used contexts obtained from the National Corpus of the Russian Language. The research employed descriptive, structural-semantic, and comparative methods. The main attention is given to the appearance of new elements in the traditional range of comparative metaphorical and similative constructions. They denote realities which have recently emerged, including those related to computer technology and terms from various fields of science. The article concludes that in modern prose texts, the range of figurative comparative constructions is expanding on the basis of genus-species and synonymic relations. The revival of comparative constructions is accompanied by frequent concretisation of figurative comparisons, which increases the size of such constructions. As a result, they can include one-word definitions, semi-predicative phrases, and subordinate clauses. Thus, the figurative comparison becomes detailed and multidimensional. At the same time, there is a tendency to a stylistic degradation of figurative comparison used in modern Russian prose.
The processes of semantic decorrelation in the word family with the root -lag-/-lozh-
Authors: Kozinets S. B.
Published: September 2023

Studying semantic processes in word families is relevant. Such research is essential for both word formation and lexicology since these transformations lead to a change in the quantitative and qualitative composition of the family (up to its disintegration), as well as to the emergence of new lexical units. The article aims to consider the processes of semantic decorrelation in the word family with the base -lag-/-lozh-. Research methods included synchronicdiachronic analysis, structural-semantic analysis of the word, inductive method consisting in the examination of case studies, analysis of verb families, and quantitative evaluation of the obtained data. The article considers the main causes of the semantic dissimilation in the word family with the root -lag-/-lozh- and the emergence of new meanings. The article concludes that the semantic dissimilation of the allophones -lag- and -lozh- is ongoing. In detail, verbs with the allomorph -lag- lose their connection with the original spatial meaning and form new, abstract meanings. The research reveals that the aspectual correlation of verbs with the allomorphs -lag- and -lozh- was largely destroyed, which led to the emergence of suppletive aspectual pairs with the roots -lozh-/-klad-.
A familiar stranger (about the conjunction libo (English or) in modern Russian)
Authors: Zavialov V. N.
Published: September 2023

The article provides a multidimensional characterisation of the conjunction libo (English or). The research is relevant due to the lack of a systematic and complete description of this conjunction in Russian studies. Nevertheless, it is an important means of expressing disjunctive relations. Libo was usually studied together with other disjunctive conjunctions, as well as in comparison with the conjunction ili (English or) although it is the second most frequent disjunctive conjunction. The research is based on the monographic method of studying function words used by the Far Eastern Syntactic School. Each such word is under scrutiny and can be considered as an organising unit of the surrounding syntactic context. The article analyses the constructional properties of the conjunction libo related to the morphological-syntactic characteristics of the word forms it connects. Moreover, the study focuses on the actual syntactic properties dependent on the peculiarities of the syntactic environment around this conjunction (such as generic words, particles, word order, intonation, etc). The research demonstrates that this conjunction is oriented to showing real options, therefore, in general, it cannot express alternative-suppositional and explanatory relations. The article characterises the pragma-stylistic properties of libo. It has been established that, like the conjunction ili, libo is stylistically neutral. Its differenfrom ili is primarily semantic although pragmatic factors are also relevant. The etymology of libo is explained. It is associated with the adjectival word form lyubo with which the conjunction retains a prototypical connection. As a result, the alternatives libo coordinates emphasise not only the different, but also the opposite. Based on the findings of the study, the key conclusion is that there is an ontologically opposed pair of conjunctions libo and ili in modern Russian. They reflect the speaker’s urge to present alternatives as compatible or incompatible.

Published: September 2023

Individuals who move from one place to another in search of recyclable goods for financial benefits or other purposes are known as wastes pickers. This study aimed on assessment of some toxico-inflammatory, hepato-renal and cardio-oxidative-stress biomarkers among wastes pickers in Ajegunle, Lagos State, Nigeria. Five milliliters of blood specimens were withdrawn from each of the 120 participants into lithium heparin anticoagulated bottles respectively. This was followed by the measurements of some biomarkers with data analyzed using SPSS version 20.0 and ANOVA used for statistical analysis. There were significant elevations (p=0.00) in the mean values for lead, cadmium (toxic heavy metals), C-reactive protein and interleukin-6 (inflammatory biomarkers) in wastes pickers with working experience of < 2 years, 2-5 years and > 5 years as compared with that of the control group . Also, there was significant elevation (p=0.02) in the mean values of alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase (liver enzymes) in wastes pickers with > 5 years working experience whereas wastes pickers with < 2 and 2-5 years working experience did not reveal any significant alterations (p > 0.05) in the mean values of these liver enzymes when compared with the control group. There were significant elevations in the mean values for glutathione peroxidase (p=0.02) and malondialdehyde (p=0.03) (oxidative-stress biomarkers) in wastes pickers with working experience of < 2 years, 2-5 years and > 5 years as compared with the control group. However, no significant alterations (p > 0.05) were seen in the mean values of creatinine and urea (renal biomarkers) and cardiovascular biomarkers (troponin-1 and creatinekinase-MB) among the wastes pickers with various working experiences. It is concluded that chronic roadside wastes pickers may be prone to risk of heavy metals poisoning, inflammatory disorder, hepatotoxicity and oxidative stress. Therefore, it is recommended that roadside wastes pickers should be embraced by the appropriate authorities and enlightened to comply with safety precautions when discharging their duties.

Authors: Chidi Juliet Nwankwo  , Lucky Obukowho Odokuma  , Chimezie Jason Ogugbue
Published: September 2023

This study evaluated the toxicity of bitumen on apparently health T. guineensis (condition factor of 1.976) over a period (24 hrs, 48 hrs. 72 hrs and 96 hrs) using standard analytical procedures. The density, API and flash point of the bitumen used in this study at 15oC was 0.9898 g/cm3, API at 60oF value of 11.46 and >200oC respectively. The total TPH and PAH constituent of the bitumen was 20,549.77 mg/l and 924.09 mg/l respectively. Analysis of the effect of different concentrations (10mg/L, 20 mg/L, 30 mg/L, 40 mg/L and 50 mg/L) of bitumen on T. guineensis revealed that the mortality of the organism increased as the concentration of the toxicant and time of exposure increased. The concentration with the longest exposure time where lowest mortality was observed was 40mg/l for 24 hours. The probit analysis on the lethal concentration (LC10, LC20 and LC50) of the toxicant on T. guineensis when exposed for 96 hours revealed a varying mortality status. The LC10, LC20 and LC50 of the bitumen on the T. guineensis was 6.746 mg/L, 10.773 mg/L and 26.38 mg/L respectively. Continuous discharge of untreated wastes especially petroleum-based products should be discouraged as it poses serious threat to aquatic habitat and produces.

Published: September 2023

Commercial fungicides Rango, Tacora, Velficur, and Opus were evaluated in the field, to determine their biological effectiveness to control karnal bunt (Tilletia indica) of wheat. A completely randomized design was used with four replications. Twenty heads of cultivar Tacupeto F2001 were inoculated during the boot stage with an allantoid sporidial suspension (10,000/mL). Commercial rates indicated in the containers of each product were followed. The first application was carried out ten days after inoculation (Zadoks stages 56-58), and the second one ten days later. Inoculated spikes were threshed by hand and the healthy and infected kernels were counted to determine the percentage of infection. Two hundred grains per treatment and per replication were weighed. The biological effectiveness of the products evaluated were Opus 91.6, Velficur 83.2, Tacora 80.2, and Rango 70.3%. The untreated inoculated check had a mean of 18.6% infection. There were no statistical differences for the products evaluated for level of infection after arcsin transformation (Tukey, p = 0.05) and the coefficient of variation was 16.2%. The average weight of 200 grains per treatment was 10.6, 10.5, 10.6, and 10.7 g, respectively, and 10.7 g for the untreated inoculated check. No phytotoxic effects of treatments applied to the wheat plant were observed.

Published: September 2023

Adrenal ganglioneuroma is a benign tumor of the sympathetic nervous system, composed of gangliocytes and mature neural stroma. The tumor is asymptomatic in the majority of cases and mostly accidentally detected in diagnostic imaging due to health check. When the tumor is large, it causes the symptom such as abdominal pain or discomfort. We report a case of adrenal ganglioneuroma incidentally detected in a 25-year-old male patient. The physical examination and laboratory tests were in normal ranges. However, abdominal magnetic resonance imaging showed a large heterogeneous right adrenal mass measuring 16.8 x 14.1 cm. Histological examination of biopies confirmed an adrenal ganglioneuroma. A right adrenalectomy by laparotomy was carried out. The right renal artery was injured during the dissection of tumor and repaired with an end-to-end anastomosis. During postoperative period, the patient experienced a pleural effusion requiring a needle aspiration. No recurrence occurred during the 6-month follow-up.

Published: September 2023

The present study evaluated the nutritional characteristics of Tapioca- a partially gelatinized starch grit made from cassava supplemented with fermented and germinated moringa seed flour. The proximate composition, mineral, vitamin, amino acid profile, functional properties and sensory attributes of the tapioca-moringa flour blends were determined. It was observed that the protein content of the flour blends increased from 2.85% − 11.05%, fat (2.42% − 8.08%) while there was reduction in carbohydrate content (82.66% − 64.90%). Calcium (6.24 mg/100 g − 8.26 mg/100 g) was the predominant mineral while copper (0.05 mg/100 g − 0.11 mg/100 g ) was the least. There was increase in vitamin A content (0.35 mg/100 g − 9.41 mg/100 g ) and vitamin C content (0.46 mg/100 g − 12.00 mg/100 g ) on supplementation of fermented and germinated moringa seed flour to tapioca flour. Total essential amino acid of the flour blends ranged from 14.15 mg/100 g − 30.42 mg/100 g . Sensory results showed that the gruel made from tapioca-moringa seed flour were scored above average for overall acceptability. Findings from this study showed that tapioca-moringa blends contain appreciable amount of protein, fibre, vitamins, minerals and amino acids and thus the flour blends could serve to alleviate malnutrition in developing countries.

Das Ziel dieser Studie ist es, die Probleme beim Erlernen des deutschen Schreibens für Studierende an der Deutschabteilung der FKIP UNPATTI zu beschreiben. Die Art der Forschung ist deskriptiv qualitativ. Die Datenerhebung erfolgte durch Fragebögen und Interviews. Die Stichprobe in dieser Studie waren 15 Studierende des drittes Semesters. Die Ergebnisse dieser Studie sind, dass die Probleme beim Erlernen des deutschen Schreibens sprachliche Probleme und methodische Probleme sind. Basierend auf den Ergebnissen der Studie kann geschlussfolgert werden, dass sprachliche Probleme, nämlich Sprachprobleme in Form der Beherrschung von Struktur und Wortschatz, immer noch die Hauptprobleme sind. Während sich methodische Probleme in Form von Ausstattung, Zeiteinteilungsmethoden, Lernstrategien und Motivation auch auf das Schreiben auswirken, hat nur die Lernumgebung keinen allzu großen Einfluss auf das Schreiben.   Die oben genannten Probleme können überwunden werden, indem den Lernenden Gelegenheiten geboten werden, sich Vokabeln zu merken, die dem Kontext angemessen sind, und das korrekte Schreiben von Strukturen und Rechtschreibung zu üben. Hoffentlich wird das Schreiben umso besser, je mehr sie das Schreiben üben.

Hazelnut, as with many other stored products, are susceptible to infestation by a variety of stored insect pests. Phosphine fumigation is a widely used method to control pests in stored products, including hazelnut kernels. This study aimed to determine the optimal exposure time for phosphine fumigation for management of stored product pests in hazelnuts. Four treatments with different exposure times (3, 4, 5, and 6 days) were conducted using various development stages of Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae), Tribolium confusum Jaqcquelin du Val, (Coleoptera: Tenebrionidae), Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), Ephestia kuehniella Zeller (Lepidoptera: Pyralidae), and Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae) together with the control group. The trials were conducted in a commercial chamber of a hazelnut processing facility. The insects were placed in plastic containers within jute sacks filled with hazelnuts, fumigations were done under gas-proof sheet and the survival rate was assessed after treatments. The results showed that a 3-day exposure period was sufficient to fully eradicate the pupal and adult stages of O. surinamensis. For T. castaneum, 100% mortality was achieved in both larvae and adults from 3 days of exposure, but the pupal stage required at least 5 days. For T. confusum, all larvae and adults died in all exposure periods, but the pupal stage required at least 4 days. In the case of the moth species, a 100% mortality rate was achieved in the larval and pupal stages of both E. kuehniella and P. interpunctella at all exposure periods. The mortality rate of E. kuehniella eggs was 99% after 3 and 4 days of exposure, and a fumigation period of 5 days was required to control the entire population. However, only 67% of P. interpunctella eggs were controlled after 3 days of exposure. The time and stage factors were found to be significant in the egg stage of P. interpunctella. The results suggest that a 5-day exposure period is the most effective for controlling tested stored product pests in hazelnuts.
