Authors: Sokolova M. I. , Zarubina E. Yu.
Published: December 2023

This work is devoted to assessing the productivity of higher aquatic and coastal aquatic vegetation and assessing the contribution of macrophytes to the formation of organic matter of the Novosibirsk reservoir. As part of the complex expedition in 2022, studies were carried out on key sections of the reservoir: Krutikhinsky shallow water (upper part), Chingis and Sharapsky bays (middle part), Karakansky, Irmensky, Burmistrovsky and Berdsky bays (lower part of the reservoir). In the course of field work, the composition of dominant communities and the biomass of air-water (helophytes), floating (pleistophytes) and submerged (hydrophytes) plants were determined. The long period of filling the reservoir in 2022 had a negative impact on the productivity of aquatic vegetation. The most productive were communities of air-aquatic plants, the average annual production of which was 418.4 ± 35 g of carbon, the average annual production of communities of hydrophytes and pleistophytes did not exceed 235 ± 21 g/m2 or 125 ± 11 g of carbon, respectively.

Published: December 2023

The results of the analysis of the composition and structure of flora of the park named after the 50th anniversary of the Komsomol in the city of Kirov are presented. The study was conducted in 2021-2022 by route-reconnaissance method in combination with geobotanical descriptions of individual communities on temporary sample plots using traditional methods. Vegetation cover is represented by plantings of Betula pendula Roth, groupings of Pinus sylvestris L. and Populus tremula L., open meadow areas, laid alleys of shrubs and trees. The flora of vascular plants includes 125 taxa from 96 genera, 37 families, three classes and two divisions. Convallaria majalis L is found in the park, its cenopopulations require constant control and monitoring of the state in Kirov region. Plants are distributed into 14 ecological-coenotic groups, dominated among them by the number of species of wet-meadow (38.4 %) and nemoral (15.2 %). In the spectrum of biological types hemicryptophytes dominate (60.8 %); in the biomorphological structure -terrestrial herbaceous polycarpics (68.0 %), among them are short-rhizomatous (20.8 %), long-rhizomatous (15.2 %) and tap-rooted (13.6 %) herbs. Flora includes plants of five stages of hemerobia; dominated by species resistant to anthropogenic impact - mesohemerobes (93.3 %); a few taxons, which may tolerate minor soil disturbances - ^-euhemerobes (75.6 %). The revealed spectra suggest that the flora has undergone little transformation during the almost 60-year existence of the park, and to be close to the original meadow community, on the site of which the park was laid out.

INTRODUCTION:

The identification of risk factors for precursor lesions of colorectal cancer (CRC) holds great promise in the context of prevention. With this study, we aimed to identify patient characteristics associated with colorectal polyps (CPs) and polyp features of potential malignant progression. Furthermore, a potential association with gut microbiota in this context was investigated.

METHODS:

In this single-center study, a total of 162 patients with CPs and 91 control patients were included. Multiple variables including information on lifestyle, diet, serum parameters, and gut microbiota, analyzed by 16S-rRNA gene amplicon sequencing and functional imputations (Picrust2), were related to different aspects of CPs.

RESULTS:

We observed that elevated serum alkaline phosphatase (AP) levels were significantly associated with the presence of high-grade dysplastic polyps. This association was further seen for patients with CRC. Thereby, AP correlated with other parameters of liver function. We did not observe significant changes in the gut microbiota between patients with CP and their respective controls. However, a trend toward a lower alpha-diversity was seen in patients with CRC. Interestingly, AP was identified as a possible clinical effect modifier of stool sample beta diversity.

DISCUSSION:

We show for the first time an increased AP in premalignant CP. Furthermore, AP showed a significant influence on the microbial composition of the intestine. Relatively elevated liver enzymes, especially AP, may contribute to the detection of precancerous dysplastic or neoplastic changes in colorectal lesions. The association between elevated AP, premalignant CP, and the microbiome merits further study.

Published: December 2023

This experiment was conducted to determine the effectiveness of different types of local biopesticides to control diamondback moth (DBM) in cabbage production in Zanzibar. The experiment was conducted in horticulture farms at Zanzibar Agricultural Research Institute. The experiment was conducted in a randomized complete block design, with 6 treatments and a control, each of which was replicated 3 times. The following plants were used as biopesticide which are garlic (T1), hot pepper (chilli) (T2), clove (T3), mixture of garlic and pepper (T4), mixture of garlic and clove (T5), synthetic insecticide (T6) and a control (T0). The parameters were evaluated by conducting initial data collection (before treatment) and final data collection (after treatment). The average number of leaves affected by DBM and yield in terms of average mass (kg) of cabbage were recorded. Results showed that T6 was significantly associated with a lowest average number of affected leaves and higher yield followed by T4 and T5. Overall, garlic-treated plots had recorded higher yield compared to the non-garlic treated plots. Therefore, garlic extract as local biopesticide can effectively repel DBM. This study recommends that garlic can be used as an alternative to using synthetic chemicals to control DBM in cabbage crop.
Fulbe z północnego Kamerunu w drodze od Kadirijji do Tidżanijji
Authors: Różański Jarosław
Published: December 2023

W XIX wieku w północnej Nigerii Fulbe umiejętnie wykorzystywali islam jako siłę motywującą i usprawiedliwiającą walkę z lokalnymi muzułmańskimi władcami. W ten sposób udało im się ustanowić regionalną potęgę - kalifat (sułtanat) Sokoto, który na długi czas podporządkował sobie feudalne struktury Fulanów w północnym Kamerunie. Do upadku potęgi i jedności kalifatu Sokoto przyczyniła się Wielka Brytania, a następnie Niemcy. Jednak w północnym Kamerunie ani Niemcom, ani później Francji nie udało się wyeliminować dominacji Fulbe nad innymi ludami (Kirdi). Przyczynił się do tego przyjęty pośredni system rządów. Nie zmieniło się to w latach niepodległości Kamerunu. Fulbe nadal pozostawali u władzy w administracji państwowej i poza nią. Jednak na przełomie XIX i XX wieku ich władza została zakwestionowana przez nowe radykalne grupy muzułmańskie. Te nowe grupy muzułmańskie de facto odwoływały się do niektórych idei i praktyk, których Fulbe używali wcześniej jako własnej broni.

Published: December 2023

Autorzy recenzowanego czasopisma podejmują refleksję na temat wolności religijnej jako szczególnego aspektu wolności z perspektyw badawczych poszczególnych nauk humanistycznych i społecznych. To zróżnicowanie form i treści, a także metod i naukowego doświadczenia poszczególnych autorów widoczne jest w pierwszym numerze recenzowanego czasopisma. Pomimo tych różnic w naukowej wnikliwości prezentowanych badaczy redaktorzy czasopisma postanowili je opublikować, wychodząc z założenia, że chociaż autorów różnią zainteresowania i podejście metodologiczne, to jednak łączy ich przede wszystkim tak potrzebne różnorodne spojrzenie na problem wolności religijnej. To szerokie pole badawcze, tak warsztatowe, jak i kulturowe (oraz geograficzne) ma tutaj fundamentalne znaczenie, gdyż wymusza wcześniej czy później interdyscyplinarny charakter badań, holistyczny ich charakter i w pewnej mierze metodologiczny kosmopolityzm. Tytuły pierwszego tomu wskazują na aktualność zawartych w nim badań, stanowiąc dość reprezentatywny przegląd aktualnych zainteresowań polskich badaczy.
Accuracy prediction of wearable flexible smart gloves
Authors: Zhang Yan , Xie Hong , Lake Mark J.
Published: December 2023

This article aimed at providing a new biomechanical three-dimensional dynamic finite element model of the hand–glove combination for exploring the distribution of the overall continuous dynamic contact pressure of the hand with the flexible glove in the state of grabbing an object, and further predicting the accuracy of sensors of wearable smart gloves. The model was validated by garment pressure experiments at eight muscle points. The results showed that the pressure value measured with three flexible gloves was highly consistent with the finite element simulation value. Based on the model, the distribution of dynamic pressure between the soft tissue of the hand and the fabric in the process of flexing the fingers and grabbing external objects were predicted accurately and effectively, which indicated that the model with high accuracy could be applied to evaluate the accuracy of the pressure value collected by sensors of smart gloves. In addition, the model had been confirmed that it has a certain application value. The findings could help to provide a reference for dynamic continuous monitoring equipment or other intelligent wearable devices, and promote the development of the intelligent clothing industry in the future.

Prognostic survival prediction in colorectal cancer (CRC) plays a crucial role in guiding treatment decisions and improving patient outcomes. In this research, we explore the application of deep learning techniques to predict survival outcomes based on histopathological images of human colorectal cancer. We present a retrospective multicenter study utilizing a dataset of 100,000 nonoverlapping image patches from hematoxylin & eosin-stained histological images of CRC and normal tissue. The dataset includes diverse tissue classes such as adipose, background, debris, lymphocytes, mucus, smooth muscle, normal colon mucosa, cancer-associated stroma, and colorectal adenocarcinoma epithelium. To perform survival prediction, we employ various deep learning architectures, including convolutional neural network, DenseNet201, InceptionResNetV2, VGG16, VGG19, and Xception. These architectures are trained on the dataset using a multicenter retrospective analysis approach. Extensive preprocessing steps are undertaken, including image normalization using Macenko’s method and data augmentation techniques, to optimize model performance. The experimental findings reveal promising results, demonstrating the effectiveness of deep learning models in prognostic survival prediction. Our models achieve high accuracy, precision, recall, and validation metrics, showcasing their ability to capture relevant histological patterns associated with prognosis. Visualization techniques are employed to interpret the models’ decision-making process, highlighting important features and regions contributing to survival predictions. The implications of this research are manifold. The accurate prediction of survival outcomes in CRC can aid in personalized medicine and clinical decision-making, facilitating tailored treatment plans for individual patients. The identification of important histological features and biomarkers provides valuable insights into disease mechanisms and may lead to the discovery of novel prognostic indicators. The transparency and explainability of the models enhance trust and acceptance, fostering their integration into clinical practice. Research demonstrates the potential of deep learning models for prognostic survival prediction in human colorectal cancer histology. The findings contribute to the understanding of disease progression and offer practical applications in personalized medicine. By harnessing the power of deep learning and histopathological analysis, we pave the way for improved patient care, clinical decision support, and advancements in prognostic prediction in CRC.
Rejection and symmetric difference of bipolar picture fuzzy graph
Authors: Almousa Maha Mohammed , Tchier Fairouz
Published: December 2023

Due to the absence of a negative of three membership functions, there are drawbacks to the existing definition of a picture fuzzy graph (PFG). In that definition of bipolar picture fuzzy graph (BPFG), membership function, neutral membership function, nonmembership function, negative of membership function, negative of neutral membership function, and negative of nonmembership function are involved. A BPFG is the extension of PFG. In this manuscript, we present some properties of symmetric difference, and rejection of BPFG.

Published: December 2023

Developing renewable energy sources has gained considerable attention recently. Solar energy is the fastest-growing alternative renewable energy source. A solar energy harvesting-based built-in backpack charger is introduced here. The proposed system aims to utilise the surrounding solar energy and overcome the power limitations of batteries installed in mobile phones in cases where power sockets are unavailable. A 6 cm × 6 cm solar module is employed. Additionally, current, voltage, and power were measured under the two scenarios; the first scenario is when the electrical load is 100 Ω, and the second scenario is when the load is a power bank. The maximum harvested power noticed in the first scenario of the resistive load was 140 mW by the proposed system in the southeast direction from 10:30 a.m. to 4:30 p.m. Moreover, the top-generated output voltage and current in this scenario were 3.6 V and 36 mA. On the other hand, 55 mW was the top value for the second scenario of the power bank as a load in the flat direction with the highest generated output voltage and current of 4.1 V and 13 mA, whereas 4.27 V was the highest generated voltage in this scenario in the west direction.
A contemporary systematic literature review of enogastronomic experiences
Authors: Mikinac Krešimir
Published: December 2023

Enogastronomic experiences are on the rise in the tourism industry, and the number of tourists travelling primarily to experience food and wine culture has increased. In addition, destination marketing organisations are increasingly using local food and wine as a differentiator when marketing a destination. Despite the growing interest in this field of tourism, there is a paucity of research on the importance and impact of enogastronomic tourism on a destination’s image. This study thus comprises a systematic literature review on these topics, summarising the current state of knowledge on these areas and highlighting the potential for future research. The purpose of this research is comprehensively presents the literature on enogastronomic experiences using descriptive statistics and cluster analysis. This paper reports on findings from a review of 85 peer-reviewed studies that focused on enogastronomic tourism from 2012 to 2023. The findings reveal evolving trends in this field of study, namely, the VOSviewer program was applied to identify the most frequently used keywords associated with the enogastronomic tourism and the most active countries in publications. To provide an even deeper understanding of this topic, future research should also include other research areas in which enogastronomy has been studied to provide an overview of interdisciplinary perspectives. In addition, further examination of the dependent and independent variables is recommended to understand what predictors and consequences of the enogastronomic experience are.

Published: December 2023

Symptoms of primary adrenal insufficiency (PAI) are commonly nonspecific, causing the disease to be misdiagnosed or often delayed, and patients may present to the hospital with a life-threatening crisis. Previous case reports have documented that patients in this condition often require lifelong glucocorticoid replacement therapy. This study aimed to present a noteworthy outcome of PAI caused by adrenal tuberculosis infection, demonstrating complete recovery after six months of glucocorticoid replacement therapy. A 38-year-old Indonesian man presented to the endocrinology clinic in a tertiary hospital with a chief complaint of epigastric pain. The patient experienced nausea, vomiting, loss of consciousness, weight loss, excessive sweat, decreased appetite, weakness, and dizziness in the past 2 weeks. Laboratory examinations revealed hyponatremia, elevated adrenocorticotropic hormone, and suppressed morning plasma cortisol level. A non-contrast-enhanced abdominal MRI showed unilateral right-side adrenal enlargement and calcification. The patient’s Mantoux test was positive. Corticosteroids and anti-tuberculosis therapy were administered. After 6 months, hydrocortisone was discontinued due to the patient’s good clinical condition and normal morning plasma cortisol levels. After a 1-year follow-up, the patient remained asymptomatic with normal cortisol levels. We hypothesized several reasons for this unique outcome: (i) the patient was relatively young compared to previous cases, suggesting an adequate immune system may play a role; (ii) despite a 1-month delay in diagnosis and treatment, the absence of skin hyperpigmentation suggested an acute presentation, potentially contributing to the favorable outcome; and (iii) the absence of comorbidities potentially positively impacted the patient's outcome.

Learning points

Symptoms of adrenal insufficiency are often nonspecific and may only become apparent once significant damage has occurred to the adrenal gland.

Clinical adjustments and a comprehensive understanding of epidemiological knowledge are necessary for diagnosing patients with endocrine diseases in limited-resource settings.

Complete recovery in primary adrenal insufficiency caused by tuberculosis infection might be due to younger age, acute presentation, and absence of comorbidities

Published: December 2023

The model of the semiconductor quantum dot with a multilayer shell and the quantum dot-human serum albumin bionanocomplex, which are contained in a living cell, was constructed. The regularities of changes in deformation of materials of the CdSe-core / ZnS/CdS/ZnS-shell quantum dot with changes in cell elasticity (comprehensive modulus) at different core radii, thicknesses of individual shell layers, and surface concentration of albumin molecules were investigated. It is shown that the presence of human serum albumin on the surface of the quantum dot significantly increases its sensitivity to pressure caused by the surrounding medium (living cell). The obtained results indicate the prospect of using the core-shell quantum dot-human serum albumin bionanocomplexes for the diagnosis of cancer diseases in the early stages. This is due to the fact that such diseases are accompanied by a sharp change in the elasticity of the cell (its elastic constants).
GÊNERO E ALFABETIZAÇÃO NO BRASIL DE 1940 A 2000: A HISTÓRIA QUANTITATIVA DA RELAÇÃO
Authors: Ravanello Ferraro Alceu
Published: December 2023

El objetivo de este trabajo es enfocar la relación entre género y alfabetización. Cuestiona la sensibilidad y adecuación del indicador ¨tasa de analfabetismo para las personas de 15 años o más¨, utilizado en varios estudios patrocinados por la UNESCO. En el texto, se argumenta que ese indicador es incapaz de captar las transformaciones en curso en la relación entre género y alfabetización, precisamente por no tener en cuenta el efecto generacional, es decir, el efecto de las distintas edades en la tasa de alfabetización o analfabetismo de acuerdo con el género. La argumentación se basa sobre todo en un estudio de caso, cuyo foco está en la trayectoria de la relación entre género y alfabetización en Brasil, durante el periodo comprendido entre 1940 y 2000. El estudio revela que ya desde el Censo 1940 (estudio estadístico demográfico) había más mujeres alfabetizadas que hombres. Esta diferencia se observaba, en principio, en los grupos más jóvenes (5 a 9 años y 10 a 14 años); sin embargo, en el Censo 2000, se extendía al grupo de 40 a 44 años. A partir de estos datos, se sostiene que lo que ocurre –y no solamente en Brasil- es una inversión histórica en la relación entre género y educación como un todo. En este trabajo, se mapean algunas hipótesis de interpretación o explicación del fenómeno en la literatura internacional. Por último, el texto se pregunta qué significados puede tener ese cambio de interpretación en términos de superación de la histórica desigualdad de condiciones entre mujeres y hombres.

Published: December 2023

El objeto de este trabajo consiste en avanzar en el desarrollo metodológico del aprendizaje basado en problemas y en su aplicación didáctica en las áreas afines a las Ciencias Sociales. En este caso, la propuesta atañe a la formación superior en Geografía. Para ello, antes que nada, conviene precisar las similitudes y diferencias con otros tipos de aprendizaje cuya propuesta se relacione con los problemas. Asimismo, conviene destacar las peculiaridades que convergen en la puesta en práctica de esta metodología, esto es, necesita unas determinadas condiciones del escenario educativo. Así, parece obvio que entre docente y alumno se establezca una peculiar dialéctica en el mencionado escenario, siendo el docente un mediador del proceso de aprendizaje. En este sentido, los postulados psicopedagógicos, que promueven y sustentan este método de trabajo, así como las técnicas empleadas para dinamizar los grupos de trabajo, resultan ser claves para el éxito. Con todo ello, tanto la selección de unos escenarios geográficos idóneos como el pautado en establecer las fases de desarrollo más apropiado para el alumnado constituyen el entramado didáctico medular para alcanzar los objetivos propuestos.

A CONSTRUÇÃO DA AUTONOMIA DOCENTE EM QUÍMICA NA EDUCAÇÃO BÁSICA BRASILEIRA
Authors: Pereira Jaqueline Ritter , Maldaner Otavio Aloisio
Published: December 2023

La necesidad de concebir la definición de la Educación Básica, como propone la LDBEN/96 provocó debates intensos acerca de cuál sería el currículum escolar más adecuado. Pasados aproximadamente quince años desde la promulgación de la Ley, el Ministério de Educación y Cultura (MEC) publicó documentos y directrices que promueven el principio de la interdisciplinaridad, contextualización y complementariedad en el desarrollo del currículum escolar como intento de superar la lógica propedéutica de la enseñanza básica en Brasil. Como resultado se busca enfatizar el desarrollo cognitivo de los estudiantes por medio de la formación de competencias y habilidades. El objetivo central de este texto es promover una discusión acerca del proceso de autonomía docente en contrapunto a la necesidad de crear currículos que puedan cumplir con lo que proponen los documentos oficiales. Fueron analizados específicamente los Programas de la Enseñanza de Química puestos en marcha en escuelas, así como el Proyecto Político Pedagógico de una de las Escuelas. La descripción y análisis de estos documentos integran el campo empírico del estudio realizado con la intención de ser desarrollado posteriormente como Disertación de Máster del mismo tema.
Que la fuerza esté contigo
Authors: Santibanez Cristián
Published: December 2023

¿Qué significa que un argumento sea fuerte? La fuerza en un argumento, en habla natural pero también en teoría de la argumentación, es muchas veces presupuesta. Salvo algunos pocos intentos reflexivos, que son parte de la revisión de la literatura que este trabajo contiene, el análisis de esta realidad argumentativa aún está en construcción, por lo que existe amplio espacio para debatir sobre qué es la fuerza argumentativa, vale decir, la fuerza de un argumento y la fuerza general de la argumentación. La principal contribución de este trabajo es que al igual que, o dado que, los actos de habla poseen una fuerza neutral o flotante, así también la tienen los argumentos. Habría, así, una fuerza intrínseca, en principio independiente del auditorio y del contexto. Es una fuerza estructural que, por cierto, tiene historia y evoluciona, pero que cuya función ulterior es asegurar un estado sistemático de diferencias de opinión.

Primary synovial sarcoma of the lung is a rare pathology, representing around 0.5% of malignant lung neoplasms. Clinically, it is manifested by pleuritic chest pain, cough, hemoptysis, dyspnea, and weight loss. Diagnosis requires a good clinical history, imaging, and clinical and immunohistochemical studies. Its treatment is not fully established. However, complete surgical resection associated with chemotherapy has shown improvements in survival. This report presents the case of a 26-year-old male patient with dyspnea, chest pain, cough, and hemoptysis. Subsequently, a mass in the left hemithorax was evidenced using radiological studies, and surgical resection was performed. The anatomopathological and immunohistochemical findings suggest synovial sarcoma, for which a co-adjuvant chemotherapeutic scheme was started; the patient had an operative site infection during hospitalization and required intravenous antibiotic therapy, with subsequent favorable clinical evolution.

TWIP steels belong to a number of modern innovative structural materials that combine a high level of mechanical characteristics and low density, which brings their specific strength closer to the level of titanium alloys. Such steels usually do not contain deficient components and they are suitable for wide commercial industrial production. The most high-strength alloys include around 20-30 % Mn (wt.), around 10 % (wt.) Al and 1% (wt.) C. Such chemical composition brings them closer to the three-phase region, in which austenite, ferrite and k-carbides can simultaneously exist. According to this, it is possible to change mechanical characteristics of such alloys in a wide range only by heat treatment. Although in practice the best results are shown by a combination of deformation and heat treatment. The Manuscript presents a study of changes in the structural and phase characteristics and mechanical properties of the Fe-24Mn-11Al-1,4C alloy, prepared by electroslag melting, in its initial state, after deformation and annealing, and after deformation with subsequent hardening and aging. A fractographic analysis of the studied samples destruction places was also carried out. It is shown that the original sample obtained by electroslag remelting has the highest plasticity and the lowest strength, which is explained by combination of largest alloying of austenite and as-cast microstructure. The deformed and annealed sample is characterized by a pronounced fine-grained structure in which carbides are separated along the grain boundaries. Such a sample exhibits a strength greater than 1.1 GPa and the lowest ductility of 4.26 %. The deformed sample after quenching and aging has a similar structure, but the carbide inclusions are much finer, and the alloying rate of austenite is higher than the previous one. Such a sample shows the highest strength of more than 1.2 GPa and plasticity of 8.6 %. Keywords: TWIP-steels, casting, deformation and heat treatment, structural and phase characteristics, fractography, mechanical properties.

Segue-se uma metodologia de revisão de literatura e diálogo entre os autores, sendo um deles um sacerdote timorense. Neste artigo destaca-se duas localidades como santuários marianos e reflete-se sobre seus significados: O santuário Nacional de Aitara, localizado em lugar sagrado, passa por ressignificação: do local da árvore da degola, passa a ser a árvore da cura; o lugar do suplício e tormento se torna alívio e alento. A “pequena menina” – a Virgem de Aitara - se torna a Grande Protetora, irradiando uma mensagem de redenção e benção para toda região. O Santuário de Nossa Senhora de Fátima, no pico Ramelau, reúne três características tradicionais para os timorenses: geograficamente está no centro do país, ocupa seu lugar mais alto, é lugar sagrado de transcendência de repouso dos antepassados. Recentemente, Ramelau se tornou também espaço real e simbólico da resistência à ocupação indonésia.
Aumento de proeminência e maximização de contraste via epêntese de glide no português brasileiro
Authors: Pereira Eberle Lucas
Published: December 2023

Este estudo investiga os efeitos da proeminência posicional e da meta funcional de maximização de contrastes nos fenômenos de inserção e apagamento de glides orais em sequências vocálicas do português brasileiro, como, por exemplo, a epêntese como resolução de hiatos, “frear – fre[j]ar”/ “voa” – “vo[w]a”, e a redução de ditongos para uma vogal simples, “cadeira – cade[ ]ra”/ “roupa” – “ro[ ]pa”. Foram realizados um teste de julgamento de aceitabilidade, em que os participantes deveriam avaliar as diferentes pronúncias de palavras reais e inventadas como “natural” ou “não natural”, e um teste estatístico de regressão logística com efeitos mistos. A partir disso, atestou-se que a epêntese em hiatos foi preferida em posições de V1 acentuada ou inicial e que o apagamento de glides em ditongos foi menos preferido em monossílabos e em todas as posições de alta proeminência psicolinguística e/ou fonética. Além disso, também foi constatado que a não inserção ou perda do glide resultaria em uma carência de sonoridade demandada por essas posições. Em relação ao contraste, ditongos com maiores dispersões na dimensão de F2 são mais resistentes ao apagamento, enquanto os ditongos menos contrastivos são mais reduzidos por serem também menos perceptivos. Embora seja bastante defendido que a epêntese ocorra no ataque da V2 em função da restrição ONSET (todas as sílabas devem ter ataque), argumenta-se que o glide se adjunge à V1 como resultado da demanda de alta sonoridade em posição de V1 acentuada, que não é satisfeita pela vogal média-alta [e o]; além de que o glide possui traços semelhantes ao da vogal precedente (V1). Por fim, conclui-se que a proeminência posicional e o grau de contraste influenciam nos fenômenos de inserção e apagamento de glides no português brasileiro.

Introduction: Plant functional traits are widely used to predict community productivity. However, they are rarely used to predict the performance (in terms of growth diameter, growth height, survival, and integral response index) of woody species planted in degraded soils. Objective: To evaluate the relationship between the functional traits and the performance of 25 woody species planted in disturbed soils affected by oil extraction activities in Ecuadorian Amazon. Methods: Eighteen permanent sampling plots were established and five 6-month-old seedlings of each 25 species were randomly planted in each plot (125 individuals per plot), at a distance of 4×4 m. Eight quantitative functional traits (leaf size, specific leaf area, leaf nitrogen concentration, leaf phosphorus concentration, leaf minimum unit, leaf dry matter content, stem specific density and leaf tensile strength) were determined for each species. Results: The woody species with high performance shows greater leaf size, specific leaf area and Stem Specific Density than those showing low performance. Leaf nitrogen concentration and stem specific density had a direct relationship with the integral response index. The leaf size, leaf phosphorus concentration, leaf dry matter content and leaf tensile strength sows a negative relationship with the integral response index. Conclusions: Our study showed that the performance of woody species o disturbed soils can be predicted satisfyingly by leaf and stem functional traits, presumably because these traits capture most of environmental and neighborhood conditions.
Composición de los macroinvertebrados según la calidad del agua en turberas de altura, Costa Rica

Published: December 2023

Introducción: En Costa Rica, las turberas altas se localizan en la Cordillera de Talamanca de 2 400 a 3 200 m. Se forman a partir de depósitos de materia orgánica en descomposición, con oxígeno reducido y baja disponibilidad de nutrientes. Objetivo: Evaluar la variación en la composición de macroinvertebrados acuáticos según parámetros fisicoquímicos de calidad del agua superficial en turberas de altura, Costa Rica. Métodos: Se colocaron 32 sustratos artificiales en las turberas para ser colonizados por macroinvertebrados. Se realizaron evaluaciones fisicoquímicas mensuales del agua superficial en ocho turberas con visitas mensuales durante la estación lluviosa. Se utilizaron los índices ICA-NSF y BMWP-CR para evaluar la calidad del agua. Resultados: Se registraron un total de diez familias correspondientes a siete géneros. Las familias más representativas fueron Chironomidae y Limnephilidae. La calidad del agua se clasificó según el ICA-NSF como de "calidad media" y como de "calidad regular a mala" según el BMWP-CR. Conclusiones: Las turberas de altura son ecosistemas poco estudiados, esta investigación evidencia la necesidad de diseñar metodologías e índices que evalúen la fauna acuática. Las turberas son diferentes entre sí, y las familias de macroinvertebrados encontrados son tolerantes a las características fisicoquímicas del agua. Es necesario realizar estudios periódicos que evalúen la calidad del agua y su relación con los macroinvertebrados acuáticos para entender la dinámica de las turberas, generar conocimiento e incrementar su protección.

Summary.

A company of these days operates in a dynamically changing business- and risk
environment, surrounded by information and communication technologies; all this
calls for thorough grounding in the field of security. This study contains the
results of expert research and was prepared based on the methodology of grounded
theory. The research examines the matter of security from the perspective of
profit-oriented companies; makes suggestions and shows tools on how to ensure
the smooth handling of security matters in this dynamic and innovative
environment, and furthermore identifies what is the determining factor in the
digital age behind the operation of the internal control system that encompasses
the company, the so-called corporate safety-net. Security represents value for
companies, its economic benefit must be shown to decision-makers. Resiliency is
important from business and security perspective as well.

The safe operation of business processes requires the appropriate management of
related risks, i.e., controlled processes, tools, or appropriate management of
human risks are necessary. A network-like relationship can be identified between
the key factors of corporate security. Safe operation requires safety-conscious,
and rule-following behaviour of the human factors. Staying up-to-date in the
digital era requires both up-to-date digital technology solutions and up-to-date
users and developers of the solutions. This can be ensured through continuous
learning and development. The security aspects of digital transformation
projects should be diligently managed from the very beginning of the development
process of the digital solution, as well as people should accept and support the
changes. The design and operational testing of controls are the keys to ensure
safe operation later on.

The key finding of the research is that the key element of the corporate
safety-net is top management commitment that is the most important factor
determining a company’s safety culture and corporate security.
A NOVEL ALGORITHM FOR FINDING ALL REDUCTS IN THE INCOMPLETE DECISION TABLE
Authors: Viet Anh Pham , Duc Thi Vu , Ngoc Cuong Nguyen
Published: December 2023

Attribute reduction, or attribute selection in the decision table, is a fundamental problem of rough set theory. Currently, many scientists are interested in and developing these issues. Unfortunately, most studies focus mainly on the complete decision table. On incomplete decision tables, researchers have proposed tolerance relations and designed attribute reduction algorithms based on different measures. However, these algorithms only return a reduct and do not preserve information in the decision tables. This paper will propose an efficient method to determine entire reducts of incomplete decision tables according to the relational database approach. In the complex case, this algorithm has exponential computational complexity. However, this algorithm has polynomial computational complexity in the different cases of databases.

In the work, a theoretical study was carried out as well as numerical simulation of the interaction of three-dimensional extremely short pulses with an inhomogeneous array of oriented semiconductor carbon nanotubes, with polarization nonlinearities of 3 and 5 orders. The results of the temporal evolution of such pulses and the dependence of the pulse strength on the parameters of the inhomogeneity of an array of oriented nanotubes are shown. Extremely short pulses (ESP), in this case, mean optical pulses of high intensity, containing one to five periods of the electromagnetic field, with a duration of up to 100 ps. The pulse frequency lies in the near-infrared range. A necessary condition for the stable propagation of extremely short pulses is the presence of nonlinear effects that would make it possible to compensate for their dispersion and diffraction spreading. Therefore, an array of oriented carbon nanotubes (CNTs), which have nonlinear properties, was chosen as the pulse propagation medium. The use of nonlinear optical media can be used to create coherent radiation sources, light sources with variable frequency, etc.
