Quo vadis, Sémiotique ? Principes sémiologaux d’une théorie du sens
Authors: Beividas Waldir
Published: January 2024

Cet article peut être considéré comme une sorte de lamentation, voire de protestation, concernant les directions que la théorie sémiotique narrative a prises après la mort de Greimas chez certains des chercheurs. Je la vois se dissoudre peu à peu, se mélanger ici et là, se submerger parfois, devant les pressions naturalistes du cognitivisme et des neurosciences, devant les philosophies analytiques et pragmatistes du langage, devant les philosophies phénoménologiques, pour ne mentionner que les pressions les plus ostentatoires. Bref, la sémiotique greimassienne a cédé beaucoup dans des concessions et a reculé assez dans les implications qui étaient contenues dans la cartographie originale de sa navigation, la cartographie du formalisme immanent d’où est parti le navire. À partir de ce constat, je cherche à argumenter, en introduisant l’idée de principes « sémiologaux » d’une théorie du sens, que la sémiotique formaliste et immanente peut encore avoir la force de manier ses rames.
Discours théoriques et temporalités discursives
Authors: Badir Sémir
Published: January 2024

Le parti pris théorique adopté par cette étude est que les théories se manifestent à travers des formes discursives et que ces formes accordent aux théories une représentation spatiale, temporelle ou spatiotemporelle. Dans cette perspective, notre étude entend envisager les formes de représentation temporelle manifestées par les théories sémiotiques. De telles formes ne connaissent pas encore de définition dans la littérature sémiotique. Notre étude s’attache à en dégager quatre à partir d’une analyse syntaxique de la notion de temps et de ses composantes définitionnelles, analyse menée sur des diagrammes. La description de ces quatre formes discursives — récit, déduction, argument et décrit — est consolidée par des rapprochements avec des conceptions, principalement philosophiques, du temps. Enfin, il est montré comment ces quatre temporalités soutiennent la modélisation des discours théoriques en sémiotique.

Published: January 2024

The chemical space is comprised of a vast number of possible structures, of which an unknown portion comprises the human and environmental exposome. Such samples are frequently analyzed using non-targeted analysis via liquid chromatography (LC) coupled to high-resolution mass spectrometry often employing a reversed phase (RP) column. However, prior to analysis, the contents of these samples are unknown and could be comprised of thousands of known and unknown chemical constituents. Moreover, it is unknown which part of the chemical space is sufficiently retained and eluted using RPLC. Therefore, we present a generic framework that uses a data driven approach to predict whether molecules fall "inside", "maybe" inside, or "outside" of the RPLC subspace. Firstly, three retention index random forest (RF) regression models were constructed that showed that molecular fingerprints are able to predict RPLC retention behavior. Secondly, these models were used to setup the dataset for building a RPLC RF classification model. The RPLC classification model was able to correctly predict whether a chemical belonged to the RPLC subspace with an accuracy of 92% for the testing set. Finally, applying this model to the 91737 small molecules (i.e., <=1000 Da) in NORMAN SusDat showed that 19.1% fall "outside" of the RPLC subspace. Knowing which chemicals are outside of the RPLC subspace can assist in reducing potential candidates for library searching and avoid screening for chemicals that will not be present in RPLC data.

Published: January 2024

Molecular heterobimetallic hydride complexes of lanthanides (Ln) and main group (MG) metals exhibit chemical properties unique from their monometallic counterparts and are highly reactive species, making their synthesis and isolation challenging. Herein, molecular Ln/Al heterobimetallic trihydrides [Ln(Tp)2(-H)2Al(H)(Nʹʹ)] 2-Ln (Ln = Y, Sm, Dy, Yb; Tp = hydrotris(1-pyrazolyl)borate; Nʹʹ = N(SiMe3)2) have been synthesised by facile insertion of aminoalane [Me3N•AlH3] into the Ln–N amide bonds of [Ln(Tp)2(Nʹʹ)] 1-Ln. Thus, providing a simple synthetic strategy to access a range of Ln/Al hydrides. Reactivity studies demonstrate that 2-Ln is a heterobimetallic hydride, for example it is able to reduce unsaturated substrates. Further evidence for the cooperative nature of 2-Ln is shown, as 2-Ln can catalytically dehydrocouple amine-borane under ambient conditions in contrast to its monomeric counterparts.
Towards AI Research Agents in the Chemical Sciences
Authors: Shir Ofer
Published: January 2024

An underlying problem shared by experimental scientists is to achieve optimal behavior of their systems and arrive at new discoveries while searching over an array of controls. Accordingly, every scientific discovery may be reduced to solving a Combinatorial Optimization problem upon formulating the characteristic array of decision variables. While AI systems already excel in navigating the landscape of possible experiments, we argue herein that they will be able to drive the entire process of scientific experimental research. Especially, in response to the so-called Nobel Turing Challenge, regarding which Kitano envisioned AI Scientists, the goal of this paper is to provide a pragmatic roadmap to obtain AI Research Agents in the Chemical Sciences. We begin by reviewing the existing integration of Computational Intelligence into experimental systems, which already benefit from solving discovery/optimization problems. We mention recent discoveries in the domains of Enzymes' Design, Material Science, Quantum Mechanics, and Postharvest, in which AI systems played active roles in attaining some ground-breaking results -- thanks to being conception-free and unbiased by flawed intuition. We then devise a concrete work plan to train agents to formulate hypotheses by Deep Symbolic Reinforcement Learning, using knowledge representations based on processed scientific textbooks. We focus on the Chemical Sciences, which possess stationary Knowledge Graphs, and propose how to obtain an independent AI system at the graduate student level for ``core Chemistry''.

An analysis of English writing errors of Kurdish EFL post-graduate students
Authors: Ali Idrees
Published: January 2024

This study aims to recognize, categorize, and assess the errors in English writing done by Kurdish post-graduate learners enrolled at Language Center (LC) of the University of Zakho, Kurdistan Region of Iraq. This is conducted via applying the error analysis technique, which is considered a vital part of EFL research. By using a quantitative and qualitative method, the researchers limited their literature review and data analysis to the writing errors by several scholars from various angles, excluding types of writing errors (i.e., interlingual and intralingual errors are the two main classifications of errors.) according to Brown (2000). Thirty-two (32) postgraduate students from different disciplines took part in this study. The major data collection tool was the students' answer sheets from the elementary and pre-intermediate academic English curriculum at different English language levels (cutting edge). The current study seeks to address the type of writing errors and how frequently such writing errors occur in Kurdish EFL students’ writing. The researchers implemented process  of  coding  for finding  out writing  errors,  and tabulated  their frequencies  and  percentages  on    bar  charts. According to the findings of this study, the participants made fourteen different types of writing errors: grammar, punctuation, spelling, capitalization, literal translation, misuse of verbs, articles, unnecessary prepositions, misuse of pronouns, subject-verb agreement, misuse of prepositions, apostrophes, misuse of conjunctions and sing of wordiness. The findings of this study also revealed that the most common errors committed by the Kurdish learners were in grammar, punctuation, using of wordiness, spelling, and capitalization. Such results are important for EFL teachers because they encourage them to pay careful attention to their students' writing errors and utilize them as pedagogical guidelines while designing activities.

The proposed research paper describes an object System of recognition based on human perception, which is achieved by feature extraction (components) and pattern analysis. Both strategies are applied to each subpart. Feature extraction is done using shaping and pattern analysis is achieved by creating statistical bins for each pattern of vehicle subparts. Each bin contains general and specific measures, and each measure has a certain weight that contributes to the analysis of each bin to decide on similarity or dissimilarity. Object recognition is an important task in computer vision, with applications in robotics, driverless cars, medical image analysis, and many other applications. This article explores the concept of product analysis using benchmarks, highlighting key concepts, methods and recent developments.
Modelación y calibración del cloro residual en el software Epanet. Caso de estudio: Municipio de Villa de Leyva (Boyacá, Colombia)
Authors: Santamaria Felipe , De Plaza Solorzano Juan Sebastián , Caicedo Alejandra
Published: January 2024

La prestación del servicio de acueducto integra un factor esencial para acceder a un nivel básico de calidad de vida y así evitar la transmisión de enfermedades patógenas en la población; dentro de la potabilización del recurso hídrico se desarrolla en las plantas de tratamiento el proceso físico químico “desinfección”, donde la concentración aplicada se realiza por el método de tanteo sin tener en cuenta el comportamiento que tiene el desinfectante en las redes del acueducto. En este sentido, en la siguiente investigación desarrollada en el municipio de Villa de Leyva, Boyacá, Colombia en el 2019, se explica el comportamiento que presenta el cloro residual libre en las tuberías de la red de abastecimiento, mediante la modelación y calibración de 3 escenarios en el software Epanet, de acuerdo con la variación de los coeficientes de reacción (KWall), (KBulk) y el coeficiente de correlación rugosidad-reacción en la pared (F).

Realizado el proceso de calibración hidráulica y de calidad, en el escenario número 1 se obtuvo un porcentaje de error entre los valores leídos y computados del 11% para las presiones y 0.3% en los niveles de cloro, de acuerdo con los coeficientes (KWall) y (KBulk) de -0.65 y (F) -2.88 que modelan la red de abastecimiento. Teniendo calibrado el primer escenario, se utilizaron los coeficientes obtenidos para iniciar la modelación del segundo y tercer escenario. Para el caso de estudio se observó que el comportamiento del cloro residual libre varía según las presiones durante el día, en los intervalos pico de consumo las presiones disminuyen y los niveles del desinfectante aumentan, debido a que el caudal se transporta con mayor velocidad por las tuberías generando menor reacción del agente químico.

Published: January 2024

The object of the research is some historical facts of the development of medicinal plant production. The subject of the research is the use of medicinal plants in environment-improving technologies and the historical prerequisites for the creation of this direction. The research question was to actualize the issue of improving the environment through the use of essential oil plants. In the 20th century, the relevance of growing medicinal plants in culture increased, new tasks were set for medicinal plant production, specialized institutes were created (VNIHFI, VILAR). The wide range of possibilities of plants opens up new horizons for scientists in the study of ways to improve the environment. VILAR scientists are conducting in-depth research in this direction. The positive effect of plants on the ecological situation and the reduction of the level of morbidity of the population has been proved. The use of medicinal plants in landscaping also contributes to the increase of biodiversity in cultivated cenoses. The Stavropol Botanical Garden is engaged in the selection of an assortment of medicinal plants for use in environment-forming technologies suitable for cultivation in the conditions of the Stavropol Upland. Species of the Lamiaceae family are under study. It has been established that these species are resistant to these climatic conditions, to pests and diseases and are suitable for use in medicinal gardens and parks.

Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, Zhukova Tatyana Yuruevna
Published: January 2024

The purpose of this study was to study the options for using a geomat with vegetation, namely the selection and selection of a mixture of herbs for the formation of herbage in the cover structure and the development of a hydraulic study technique. This article describes the study, which was aimed at studying the features of the formation of herbage of different grass seeds in the structure of the geomat. The features of the grass stand formation were studied and the most suitable grass variety for its use as part of a coating consisting of a geomat was determined. The results of these studies are necessary for the further application of a coating consisting of a geomat filled with soil with sowing of perennial grasses, as well as for determining its hydraulic characteristics, such as the roughness coefficient. An experimental setup for studying the hydraulic characteristics of an anti-erosion coating, a geomat with vegetation, is considered. A technique is described for determining the hydraulic characteristics with the refinement of the roughness coefficient of an anti-erosion coating consisting of a geomat filled with soil with sowing of perennial grasses. The use of this coating will give the slope of the soil structure a natural look without loss of protective properties. Also, thanks to the sowing of perennial grasses, the use of this coating will increase the environmental performance of the structure.
Simulation of the maximum flow hydrograph as a part of the problem of flood transformation through a hydraulic system
Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, Ratkovich Lev Danilovich
Published: January 2024

Modeling ofthe maximum flow hydrographs during spring flood is interpretedas part of a more general task as extreme floods transit throw spillway structures accounting the cutting of maxima in flood control reservoirs. A general statement of the problem related to solving the problem of floods and related economic and environmental damages requiring carrying out complex compensatory and protective water management and hydraulic engineering measures is formulated. The solution of the general problem is not considered, but the authors’ link to the relevant publications is given. The presence of important infrastructure facilities, industrial enterprises and agricultural land can significantly reduce the class of structures. The method of modeling a maximum hydrograph using the Pearson type I differential distribution function for the cases of single-peak and two-peak hydrographs is proposed. Taking into account previous studies of research, the coefficients of completeness of hydrograph form and asymmetry are accepted as criteria for the correspondence of full-scale and simulated hydrographs. A theoretical justification is given and formulas are derived for the functions of maximum flow and flood volumes depending on time. The modeling algorithm is implemented in an Excel environment using built-in statistical beta distribution functions and an optimization procedure “solver”. Excel program is presented for a set of average parameter values, outlines of hydrographs are constructed depending on the shape coefficient, as well as nomograms of the relationship of the asymmetry coefficient with the shape coefficient depending on the ratio of the maximum flow rate and the volume of the flood. Methodology for a two-peak hydrograph is also considered, which is illustrated by the example of the Sursky hydroelectric complex on the Sura River.

Published: January 2024

The purpose of the research is to study the features of the movement of particles, aggregates and geological bodies (landslides) downhill under the influence of a number of natural and man-made factors, to study the most common natural and man-made objects that reduce the activity of the development of slope processes. Two of the most common slope exogenous geological processes are considered – surface flushing and landslide. These processes contribute to the entry of silt fraction into the sediments of water bodies. The study of pollution of water bodies with heavy metals still remains relevant when assessing the geo ecological state of the environment. On the Volga River basin the principles are proposed and the zoning is presented. According to natural and technogenic objects, four categories of sites were allocated hierarchically for monitoring the pollution of the territory with heavy metals. The zoning of the bed of water bodies for the distribution of silty sediments – sorbents of pollutants was carried out. The elements of the energy approach are presented, giving an understanding of the most likely locations of pollutants – energy traps and potential barriers. Practical examples of the spread of pollutants in the natural and man-made environment and the interaction of natural and man-made processes in the landslide system are given. For the landslide process, the most typical interactions between a geological body and man-made objects are presented. On the example of the most typical landslides for the European part of Russia, the measures aimed at their stabilization, as well as the impacts contributing to their activation, are presented. Natural and man-made potential barriers to the landslide process are considered.

Published: January 2024

The purpose of the research is to analyze the water availability and geo ecological situation in the catchments of the rivers in Klinsky district in Moscow region. The characteristic of aquifers used for domestic drinking water supply is carried out and the dynamics of groundwater intake in recent years is analyzed. It was revealed that the main reason for the decrease in water intake is an increase in the efficiency of water supply network up to 0.8…0.89 as a result of repair and reconstruction. In the dynamics of changes in the structure of water consumption, the following trends have been identified: water losses reduction as a result of reconstruction and modernization of water supply networks; water consumers increase due to economic development of the district; total water consumption decrease due to the reduction of water losses and the introduction of advanced water use technologies. The main consumer of water resources is the population (45, 48%, respectively), the second main water consumer is industrial enterprises (40…43%). The influence of the depression funnel around the Northern VZU on the water supply in the Klin district with groundwater which is about 83% of the total water intake, is taken into account. The main causes of groundwater pollution have been identified.

Published: January 2024

The aim of the study is to identify features of long-term variability of the moisture state of the vegetation and soil cover of the steppe zone of northern Kazakhstan. To identify the peculiarities of the variability of the state of natural humidification of landscapes (vegetation and soil) during the growing season of the long-term time interval (from 1976 to 2020), data from satellite images of the territory of the Ishim River Valley and the city of Atbasar, located in the Akmola region of the Republic of Kazakhstan, were analyzed. Based on the data of long-term meteorological observations and on the results of decryption of satellite images, the variability of the NDMI humidity index (normalized difference index of moisture in vegetation and soils) for 44 years for the period 1976‑2020 was characterized. The NDMI humidity index has increased values and intensity of color in the images at the air temperature below the norm (or near the norm) and the amount of precipitation above the norm for this territory. The NDMI humidity index has lower values at air temperatures above normal (or near normal) and the sum of precipitation below normal for a given territory. The low degree of moisture in vegetation and soil at the time of satellite survey is preceded by the arid previous 30-day period (also vice versa). A color scale of gradation of the NDMI humidity index values for use in assessing the humidity of the landscapes of Akmola region and adjacent territories of the northern part of Kazakhstan is proposed.

Published: January 2024

Background: HBsAg positive pregnant women are responsible for around 50% of the global disease burden. Hepatitis B is caused by inflammation or infection of liver cells caused by the HBV virus. Pregnant women with hepatitis B can experience increased levels of cytokines which then cause pregnancy disorders. This study aims to examine the effect of pregnancy with hepatitis B on the incidence of preterm birth and Gestational Diabetes Mellitus (GDM).
Subjects and Method: This study is a meta-analysis study and a systematic review. The articles used were obtained from several electronic databases including PubMed, Science Direct, Research Gate, and Google Scholar. The articles used in this study were articles that have been published from 2012-2022. The keywords to search for articles are as follows Pregnancy AND (“Hepatitis B” OR HBV OR HBsAg) AND (“pregnancy outcome” OR “fetal outcome”) AND (“preterm birth” OR “preterm delivery” OR premature) AND (“gestational diabetes mellitus” OR GDM). The researched article is a complete text with an observational study design. Articles were collected using the PRISMA diagram, and analyzed using the Review Manager 5.4 application.
Results: A total of 14 prospective and retrospective cohort studies were analyzed. Articles were originated from China, Hong Kong, France and Botswana. Hepatitis B in pregnancy increased the risk of preterm birth (aOR=1.20; CI 95%=1.09 to 1.33; p<0.001) and gestational diabetes mellitus (aOR= 1.20; CI 95%= 1.12 to 1.28; p<0.001).

Formação de professores de escrita de sinais
Authors: Lima Israel Queiroz de , Sousa Alexandre Melo de
Published: January 2024

A Língua Brasileira de Sinais (Libras) é produzida pelas mãos e compreendida pela visão. Trata-se de um elemento linguístico e cultural da pessoa surda. Durante muito tempo acreditou-se que as línguas de sinais eram ágrafas, porém, desde 1972, as línguas de sinais passaram a ter um registro gráfico que documenta a história do povo surdo, descobertas, narrativas e produções cientificas. Este artigo objetiva descrever a formação de professores de Escrita de Sinais na Região Norte do Brasil, que atuam nas Licenciaturas em Letras Libras. A abordagem adotada foi a qualitativa, de natureza básica, cujos objetivos são delineados a partir da visão explicativa, numa perspectiva crítica dos dados, com base no referencial teórico. O procedimento se pautou na análise de campo, de entrevistas semiestruturadas realizadas com 6 participantes: 3 surdos e 3 não-surdos. As análises mostraram que as formações se dão de forma muito variável e com carga-horária diversificada. Há ainda pouca atenção à questão do letramento e da importância da Escrita de Sinais para a valorização da cultura surda. Concluímos, desse modo, que a disciplina Escrita de Sinais é muito importante como componente de formação de professores de Libras e para a educação de surdos, seja como sistema de registro linguístico, seja como marca de cultura e da identidade surda. Trata-se, como a maioria dos participantes da pesquisa ressaltaram, de um elemento de língua, de cultura e de inclusão da pessoa surda que reflete seu modo de ver o mundo, levando em conta suas características peculiares de visualidade.

O artigo verifica as mudanças promovidas pela Organização das Nações Unidas para a Educação, a Ciência e a Cultura (UNESCO) na definição de uma agenda política para a Educação de Adultos na América Latina. A partir de uma análise documental, referenciada no materialismo histórico-dialético, observou-se que o emaranhado de denominações indica um alinhamento com as contrarreformas neoliberais que estão sendo enfrentadas pelos movimentos e organizações sociais mantendo os princípios contra sistêmicos da Educação Popular.

“Espolones y poder”
Authors: Gatta Massimo
Published: January 2024

Este artículo tiene como objetivo explorar los cambios y continuidades en los usos y significados de la pelea de gallos en Durango desde finales del siglo XVIII hasta mediados del XIX. La investigación busca analizar cómo este fenómeno ha funcionado como un lente para comprender las estrategias de control gubernamental y los usos heterodoxos de la sociedad duranguense. Se utilizan fuentes históricas estatales y municipales que incluyen concesiones del asiento de gallos, incidentes en las galleras y normas de combate, lo que proporciona una perspectiva sobre los valores éticos y morales de los representantes del poder y sobre los usos heterodoxos de este juego. El análisis revela la tensión entre las autoridades y los grupos populares en relación con el juego de gallos e ilustra cómo la cultura persiste a pesar de los cambios y conflictos; además, muestra que las expresiones tradicionales pueden desafiar e influir en los sistemas de poder establecidos. Este estudio contribuye a la comprensión del papel de la pelea de gallos en la cultura e historia de Durango, y sienta las bases para futuras investigaciones sobre el tema, resaltando la importancia de este fenómeno en la formación de la identidad cultural y los espacios urbanos.

Authors: AKÇAY Selma
Published: January 2024

Bu çalışmada, periyodik dalgalı bir kanalda laminar pulsatif akışın hidrolik ve termal davranışları üzerindeki etkileri sayısal olarak analiz edilmiştir. Sayısal çözümler, sonlu hacim yaklaşımı ile analiz yapan FLUENT programı ile gerçekleştirilmiştir. Çalışmada, pulsatif genlik (A), Strouhal sayısı (St), Reynolds sayısı (Re) değiştirilmiş, diğer parametreler sabit tutulmuştur. Dalgalı kanalın alt ve üst yüzeyleri T=350K sıcaklığında korunmuştur. Sayısal sonuçlar, Nusselt sayısı (Nu), sürtünme faktörü (f) ve termo-hidrolik etkinlik (THE) açısından sürekli akış şartları ile karşılaştırılarak sunulmuştur. Pulsatif parametrelerin ve Reynolds sayısının kanal içindeki davranışını gözlemlemek için anlık akış ve sıcaklık dağılımları elde edilmiştir. Çalışma sonuçları, kanal içindeki akışın kanal geometrisinden, pulsatif parametrelerden ve Reynolds sayısından önemli derecede etkilendiğini göstermiştir. Artan Reynolds sayısı ve pulsatif parametreler ile hafif bir basınç düşüşü ile ısı transferinde kayda değer bir iyileşme sağlanmıştır.

Published: January 2024

In this study, an interface design was carried out in order to provide convenience to the user in the control and monitoring of the Robot Operating System (ROS) based autonomous mobile robot (AMR). Qt Designer and Python were used in the interface design. Thanks to the designed interface, autonomous and manual control of AMR was provided. Using the gmapping algorithm, the environment in the virtual world was mapped and transformed into a picture in .png format and visualized in the interface. The location information from the ROS was transferred to the said picture and the instant tracking of the AMR was done via the interface. It was shown which algorithm is used locally and globally at that moment. While in autonomous mode, the vehicle was provided to move to the previously recorded point. The total distance and time spent by the AMR while moving between two points were also calculated by the interface. The location (x, y, z) and orientations (x, y, z, w) of the previously recorded station were monitored from the stop list. On the other hand, the position (x, y, z) and orientation (x, y, z, w) information of the AMR could be followed as real time via the interface. In this way, when the AMR reaches the goal station, the time elapsed between two points, the transportation distance, settlement information such as the location and orientation of the vehicle can be tracked and be compared via the interface.
