The Sviyaga River is a water resource, and a recreational facility. It is rich in fish, therefore the assessment of ecological processes in the Sviyaga river is relevant and has theoretical and practical significance. The relevance and practical significance of research is increasing due to the plans to use the Sviyaga river bays for aquaculture development.
The purpose of the study was to examine the nature and direction of ecological processes in the Sviyaga River bays on the territory of the Ulyanovsk region.
Materials and Methods. The assessment of the bay water quality was carried out according to organoleptic, hydrochemical and hydrobiological parameters.
Results. Organoleptic water parameters in both bays met the requirements for natural waters. The maximum water temperature in summer reached 24–26 ºС, the average temperature was 20.5 ºС. The amount of dissolved oxygen (6.5 mg/l) corresponded to the optimal values for the life of many fish species, and pH level showed weak water alkalinity. Hydrochemical bay water composition indicated high organic pollution. In both bays, and in the Sviyaga river itself, the content of heavy metals and petroleum products was several times higher than the threshold limit value. BOD5 level in the bays significantly exceeded the limit values. BOD20 and chemical oxygen demand exceeded the standards four times. The results of a microbiological study revealed significant water contamination with Escherichia coli. The species composition of the aquatic phytocenosis in both bays largely corresponded to the Sviyaga River phytocenosis structure. However, the bays are characterized by plant species and ecological processes that indicate the initial stages of their waterlogging.

The aim of the study is to evaluate the characteristics of remodeling of the blood vessel plexus of the fourth ventricle and the angioarchitecture of cerebellum in rats being exclusively on high-protein and high-fat diets.
Materials and Methods. The study was conducted on white male rats weighing 200–250 g. The first group (n=5) consisted of intact rats kept on a standard food; the second group (n=5) included animals kept on a high-fat diet; the third group (n=5) enrolled rats being on a high-protein diet. Remodeling of the blood vessel plexus of the fourth ventricle of cerebrum and angioarchitecture of the cerebellum was assessed on the 15th and 30th days of the experiment. Circulatory bed and structural changes were assessed on histologic specimen (hematoxylin-eosin and van Gieson's stain). The content of cholesterol, glucose, total protein and albumin was determined in blood serum. SPSS 16.0 was used for statistical analysis. The significance of differences was determined by Student's test at p<0.05.
Results. Rats kept on an exclusively high-fat diet demonstrated a significant (p<0.05) increase in the levels of total cholesterol, glucose and albumin in the blood serum compared to the control group. In animals being on an exclusively high-protein diet, the level of total serum protein increased by 69 % (p<0.05), albumin – by 46 % (p<0.05). High-fat diet led to the spasm of the blood vessel plexus of the fourth ventricle, thickening of the basement membrane of the villi capillaries, clearing of the cytoplasm with subsequent disruption of the capillary wall integrity and hemorrhage. In the cerebellum, the plethora of arteries and veins was observed; in the molecular layer, the concentration of basket and stellate cells decreased. High-protein diet led to hyperemia of the blood vessel plexus of the fourth ventricle and the vessels of the cerebellar cortex without vascular and tissue disorders.
Conclusion. High-fat diet led to remodeling of the basement membrane, clearing of the cytoplasm, nuclei swelling, capillary wall spasm of the blood vessel plexus of the fourth ventricle, and chromatolysis of the Purkinje cell nuclei. High-protein diet was characterized by hyperemia of the blood vessel plexus of the fourth ventricle and cerebellum, and by hypertrophy and hyperplasia of Purkinje cells. High-fat diet caused more pronounced remodeling of the blood vessel plexus of the fourth ventricle of cerebrum and the cerebellar cortex compared to a high-protein diet.

The aim of the study is to identify risk factors for the development of postoperative cardiac and respiratory complications in patients after lobectomy and to develop nomograms to predict such complications.
Materials and Methods. From January 2020 to August 2023, 411 lobectomies were performed in patients with non-small cell lung cancer in the surgical department of thoracic oncology, Regional Clinical Oncology Dispensary (Ulyanovsk). The present study included 162 patients according to the designed enrolment criteria. The authors identified statistically significant risk factors for the development of severe cardiac and respiratory complications after lobectomy with systematic lymph node dissection.
Results. Due to insufficient data cardinality, artificial data with a similar distribution were synthesized using the MICE method (multivariate imputation by chained equations). The sample is divided into training (n=1258) and validation (n=342) datasets at a ratio 80 to 20. Final testing of the initial data was carried out (n=162).
Logistic regression for respiratory complications: respiratory complications = 23.4232 – 0.7427 × stair climbing test – 0.0259 × shuttle walking test. Based on these data, a nomogram was constructed to predict the development of respiratory complications. Error matrix characteristics: accuracy – 0.95; sensitivity – 0.86; specificity – 0.97; positive predictive value – 0.86; negative predictive value – 0.97.
Logistic regression for cardiac complications: cardiac complications = 11.1147 – 0.1247 × stair climbing test – 0.1651 × ejection fraction + 0.1568 × BMI + 1.133 × hypertension. Based on these data, a nomogram was constructed to predict cardiac complications. Error matrix characteristics: accuracy – 0.91; sensitive-
ty – 0.63; specificity – 0.98; positive predictive value – 0.9; negative predictive value – 0.92.
Conclusions. The developed prognostic models allow us to determine the risk group among patients who are planning a lobectomy for lung cancer at the preoperative stage. It also allows us to ensure high-quality prevention for these complications in patients at high risk.

Published: April 2024

All types of smoke are carcinogenic. Increasing air smoke is a serious global problem. Knowledge on carcinogenic effects of various types of smoke is necessary to work out effective preventive measures.
The purpose of the review is to characterize the general characteristics and peculiarities of the carcinogenic effects of various types of smoke. The most significant carcinogens of all types of smoke are polycyclic aromatic hydrocarbons, heavy metals and carbon microparticles. Any smoke is an etiological factor for respiratory tract cancer, and systemic neoplasms (tumors of hematopoietic and lymphoid tissues, central and peripheral nervous systems, soft tissues and skeleton). Tobacco smoke may be involved in the pathogenesis of cervical cancer due to the induction of local immunosuppression and specific tropic nitrosamines. Exhaust fumes due to high benzene content may cause hematological malignancies, especially leukemia in children. Wildfire smoke, due to significant amounts of ultra-fine carbon particles PM0.1, contributes to the development of central nervous system tumors. Severe contamination with natural and artificial radionuclides makes wildfire smoke a factor of high carcinogenic danger for the human population globally. Prevention of malignant neoplasms caused by smoke requires government measures to promote smoking cessation, hybrid and electric engines in automobiles, as well as wildfire prevention, early detection and extinction. Effective respirators and indoor air filters should be used for personal protection. To relieve environmentally caused oxidative stress, herbal medicines and food products that stimulate autophagy, as well as transfer factors for immunodeficiency correction, are recommended.
MANAGEMENT OF A PERIPROSTHETIC INFECTION AFTER TOTAL LEFT KNEE REPLACEMENT USING AN ORIGINAL METHOD FOR ARTICULATING SPACER MANUFACTURING: CASE STUDY
Authors: Efremov Ivan Mikhaylovich , Midlenko Vladimir Il'ich
Published: April 2024

Periprosthetic infection (PPI) is one of the most severe complications after total knee replacement. While managing patients with chronic deep PPI after total knee replacement, two-stage revision arthroplasty with intermediate installation of an antimicrobial knee joint spacer is used. The advantage of an articulating spacer is the ability to maintain motor activity until reimplantation of a permanent endoprosthesis. However, factory moulds including 3D-printed are not always available in routine clinical practice, given the high cost and limited equipment accessibility.
We present a case study of a patient with chronic deep PPI after total left knee replacement. An original method of intraoperative manufacturing of the tibial component of the articulating spacer was used in the course of treatment. The technique involves sterile mould making using a fitting plastic liner and soft polymer mass. Bone cement impregnated with antibacterial drugs is placed into the mould. When the bone cement hardens, a tibial spacer component is ready. The sterilized femoral and fabricated tibial spacer components are implanted using antibiotic-impregnated bone cement. If it is not technically possible to use fitting inserts, a previously removed plastic insert from the endoprosthesis can be used. The developed original method has a number of advantages: individual selection of spacer sizes, independent addition of the required quantity and type of antibacterial drugs, and economic efficiency. Successful infection relief in the patient allowed further revision endoprosthetics with installation of a permanent endoprosthesis.

The purpose of the work is to analyze the effectiveness of the FERTILE microfluidic sperm sorting chip.
Materials and Methods. The technique under consideration is currently experimental. It was used in patients after obtaining voluntary informed consent. A retrospective analysis of medical records of 4 groups of patients was carried out. The patients were divided into 2 experimental and 2 control groups. In total the authors analyzed 54 medical records. The microfluidic sperm sorting chip (FERTILE/FERTILE PLUS CHIP) are intended for the selection of normal mobile spermatozoids, which can be used for in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). The indicators of preimplantation embryo development in vitro were assessed.
Results. Embryological parameters of infertility treatment using ART were analyzed. Key indicators of preimplantation embryo development (fertilization rate, blastocyst development, embryo cryopreservation) were higher in both experimental groups compared to control ones (standard semen processing). Embryos were obtained by fertilization with sperm which undergone microfluidic sorting. Embryo culture suggests a more physiological nature of gamete separation. During standard ejaculate processing centifugation is used to obtain a fraction of active sperm. However, it negatively affects the cytophysiology of male gametes and causes breaks in the DNA chain in the spermatozoid head.
Conclusion. The authors observed the improvement in embryological parameters of in vitro embryos, which were obtained by means of microfluidic chip-based sperm selection. This method allows us to select cytophysiologically competent sperm and improve the embryo quality without increasing DNA fragmentation rate.

Authors: Martsev Anton Andreevich
Published: April 2024

The purpose of this study is to assess health risks in children and the impact of air pollution from industrial enterprises in the Vladimir region on children’s health.
Materials and Methods. The author analyzed official statistical digests Public Health in the Vladimir Region for 2005–2019. Based on relative data on primary child morbidity according to International Classification of Diseases (ICD-10 version), the values for real (epidemiological) health risks were calculated for Vladimir administrative regions. Data on environmental conditions were obtained from the annual reports On Environmental Conditions and Public Health of the Vladimir Region for 2001–2019. The average long-term emission load coefficient was calculated, and priority air pollutants for the region were identified. To identify probable correlation between air quality and public morbidity, a correlation analysis was carried out to determine the Pearson correlation coefficients and Spearman rank correlation.
Results. In the Vladimir region, children in most administrative territories have high morbidity risks according to classes of circulatory system diseases; blood, hematopoietic organs, certain disorders involving the immune mechanism (D50–D89) and nervous system diseases (G00–G99). Analysis results revealed administrative territories characterized by very high risk values and the largest number of disease classes. Priority air pollutants in the region are carbon oxide, nitrous oxide, sulphur oxide, methane, ammonia and inorganic dust containing 70–20 % of silicon dioxide. Correlation analysis identified a number of statistically significant correlations between priority pollutants and the morbidity risks in children according to various disease classes. The values of the potential hazard index can be used as variables when carrying out mathematical calculations in the population health - environment system.

On a tenté ici de faire un point sur trois ensembles de descriptions théoriques de l'orthographe française et de voir comment ces théories intègrent la dimension phonographique de notre écriture, comment elles cernent la notion de phonogramme. Nous avons en fin de parcours exposé l’état de nos réflexions personnelles. Un arrêt sur quelques images en quelque sorte, puisque cette contribution ne prétend pas à l’exhaustivité. Une déambulation par laquelle on peut voir que selon les approches le phonogramme se dessine dans des contours multiples.
Prononciation et situations de lecture : données sociolinguistiques, approche expérimentale, modèles psycholinguistiques
Authors: Chevrot Jean-Pierre
Published: April 2024

Dans le cas de variations phonétiques se manifestant par la suppression d’un phonème — par exemple, la suppression du | R | final dans «quat' sous» — l’orthographe note généralement la variante longue, qui est souvent la variante valorisée par les jugements d’ acceptabilité. Les travaux présentés ici montrent comment cette correspondance de fait entre graphie, forme longue et variante valorisée influence la production et l’évaluation des variantes phonétiques pendant la pratique de la lecture à voix haute chez des enfants de 10-12 ans. Premièrement, une enquête sociolinguistique établit que le | R | final est moins souvent supprimé lors de la lecture oralisée qu’en situation de dialogue. Ce premier résultat est complété par une expérimentation qui suggère que cette diminution des suppressions en lecture ne résulte pas seulement de l’incidence globale de cette situation réputée formelle, mais aussi de l’existence d’une correspondance régulière entre le phonème | R | et la lettre «r». Deuxièmement, un montage expérimental inspiré de la technique du matched guise montre que les jugements d’acceptabilité sont plus conformes à la norme qui valorise la présence du [r] lorsque les jeunes auditeurs évaluent les variantes enregistrées tout en lisant les mots porteurs des variations. Une interprétation dans un cadre psycholinguistique permet de rendre compte de ces résultats et d’expliquer comment la fréquentation scolaire des séances de lecture à haute voix pourrait modifier à terme le traitement des phonèmes variables dans les situations ordinaires de communication.

Alternativas táticas do processo de gerenciamento de crises policiais: uma nova perspectiva teórica
Authors: Silva Marco Antonio da
Published: April 2024

O objetivo do artigo é propor uma nova perspectiva teórica sobre as alternativas táticas da doutrina de gerenciamento de crises policiais, atualizando sua categorização para facilitar as aplicações práticas e melhorar as análises estatísticas, especialmente sobre a negociação tática e sobre as intervenções realizadas pelos operadores táticos nas ocorrências críticas. Como metodologia utilizou-se de pesquisa bibliográfica com abordagem quantitativa e qualitativa de análise dos dados. Os resultados apresentaram 251 ocorrências críticas atendidas pelas equipes especializadas do Batalhão de Operações Especiais (BOPE) da Polícia Militar do Paraná (PMPR) de 2003 a maio de 2023, perfazendo 20 anos de registros. Conclui-se que a negociação é a alternativa mais aplicada nas crises, e a opção “negociação tática” esteve presente na maioria das respostas que terminaram em ações táticas, justificando a nova perspectiva sugerida. Além disso, os dados demonstraram a necessidade de se propor uma reorganização das opções relativas às ações táticas, principalmente pelo fato de que os desfechos de algumas crises não se enquadraram em nenhuma das opções existentes.
On the energy security and the apologies of the extraction: the case of the industrial gas pipeline of the Huasteca Potosina, Mexico
Authors: Jacobo-Marín Daniel
Published: April 2024

This article analyzes the hegemonic argument on energy security and its configuration as the main postulate of the Mexican model of hydrocarbon extraction. It is discussed that energy security has been used in the official discourse to specify the dominant paradigm of production, use and consumption of fossil energy, consolidating the apology for extraction. The methodology is built based on a specialized selection of literature and a legislative review, as well as field work. The research is oriented towards the dialogue between theory and praxis, articulating three critical elements: (1) extractivism, (2) energy security, and (3) strategic litigation. It is concluded that the collective construction of legal-political strategies contributes to the jurisdictional defense of territorial rights.
Estimating the GHGs and the MAC of Agricultural Production Systems in China
Authors: Niu Jinye , Yu Han , Jin Gui
Published: April 2024

As the second largest source of greenhouse gas (GHG) emissions, the agricultural system has an arduous task of reducing emissions. There is an urgent need to think about how to achieve the goal of peaking carbon emissions in agricultural production at the lowest cost. This paper applied the Intergovernmental Panel on Climate Change (IPCC) factor method to calculate the GHG emissions of China’s agricultural production systems and deconstruct it into the crop farming and animal husbandry sectors. Input–output indicators based on parametric directional distance functions were constructed to assess the green production efficiency (GPE) of different agricultural sectors and scientifically quantify the marginal abatement costs (MACs) of different GHGs. The results showed the following: (a) During 2000 to 2020, GHG emissions from China’s agricultural production systems averaged 87.73 million tons of CO

emissions accounted for the largest average proportion of 55%, mainly animal enteric fermentation and rice methane emissions. (b) The average level of agricultural GPE in China is 0.79, and 0.76 for crop farming is slightly higher than 0.67 for animal husbandry. (c) The average MAC is 1,861.71 yuan/ton CO

-eq, and it is increasing year by year. The shadow price is positively correlated with the efficiency level. The “high-efficiency–low-cost” areas are key areas for agricultural emission reduction, such as Henan and Shandong provinces. Formulate emission reduction strategies according to the characteristics of regional GHG emissions to promote the realization of the “dual carbon” goal of agriculture.

Accumulated evidence highlights that exercise can modulate multiple cytokines, influencing transcriptional pathways, and reprogramming certain metabolic processes, ultimately promoting antitumor immunity and enhancing the efficacy of immune checkpoint inhibitors in cancer patients. Exploring the mechanisms behind this will, for one thing, help us uncover key factors and pathways in exercise-assisted cancer immunotherapy, offering more possibilities for future treatment methods. For another, it will support the development of more personalized and effective exercise prescriptions, thereby improving the prognosis of cancer patients.
FM-FCN: A Neural Network with Filtering Modules for Accurate Vital Signs Extraction
Authors: Zhu Fangfang , Niu Qichao , Li Xiang , Zhao Qi , Su Honghong , Shuai Jianwei
Published: April 2024

Neural networks excel at capturing local spatial patterns through convolutional modules, but they may struggle to identify and effectively utilize the morphological and amplitude periodic nature of physiological signals. In this work, we propose a novel network named filtering module fully convolutional network (FM-FCN), which fuses traditional filtering techniques with neural networks to amplify physiological signals and suppress noise. First, instead of using a fully connected layer, we use an FCN to preserve the time-dimensional correlation information of physiological signals, enabling multiple cycles of signals in the network and providing a basis for signal processing. Second, we introduce the FM as a network module that adapts to eliminate unwanted interference, leveraging the structure of the filter. This approach builds a bridge between deep learning and signal processing methodologies. Finally, we evaluate the performance of FM-FCN using remote photoplethysmography. Experimental results demonstrate that FM-FCN outperforms the second-ranked method in terms of both blood volume pulse (BVP) signal and heart rate (HR) accuracy. It substantially improves the quality of BVP waveform reconstruction, with a decrease of 20.23% in mean absolute error (MAE) and an increase of 79.95% in signal-to-noise ratio (SNR). Regarding HR estimation accuracy, FM-FCN achieves a decrease of 35.85% inMAE, 29.65% in error standard deviation, and 32.88% decrease in 95% limits of agreement width, meeting clinical standards for HR accuracy requirements. The results highlight its potential in improving the accuracy and reliability of vital sign measurement through high-quality BVP signal extraction.

В статье представлен обзор литературы, основанный на поисковых базах Medline, Embase, PubMed, научной электронной библиотеке eLibrary, с момента их создания до 31 мая 2023 г. Клеточные технологии являются перспективными в лечении хронических неинфекционных заболеваний полости носа, таких как аллергический ринит и хронический полипозный риносинусит. Использование терапии на основе мезенхимальных стволовых клеток приводит к снижению продукции провоспалительных цитокинов, подавлению иммунного воспаления и стимуляции регенерации тканей в месте их введения. Мезенхимальные стволовые клетки способны распознавать поврежденный участок и индуцировать иммунный ответ как врожденного, так и адаптивного иммунитета в случае недостаточного иммунного ответа. С другой стороны, они подавляют функцию иммунных клеток, если в поврежденном участке формируется избыточная иммунная реакция. Таким образом, в зависимости от уровня секреции факторов воспалительной среды мезенхимальные стволовые клетки проявляют либо провоспалительную, либо противовоспалительную функцию. Дальнейшее изучение иммунных процессов при хронических неинфекционных заболеваниях полости носа будет способствовать появлению новых, более эффективных методов лечения, основанных на клеточной терапии.

The article presents a literature review based on the Medline, Embase, Pubmed search databases, eLibrary scientific electronic library from the moment of their creation until May 31, 2023. Cellular technologies are promising in the treatment of chronic non- communicable diseases of the nasal cavity such as allergic rhinitis and chronic polypous rhinosinusitis. The use of mesenchymal stem cells leads to a decrease in the production of pro-inflammatory cytokines, suppresses immune inflammation and stimulates tissue regeneration at the injection site. Mesenchymal stem cells are capable of recognizing a damaged site and inducing an immune response of both innate and adaptive immunity in case of an insufficient immune response. On the other hand, they suppress the function of immune cells if an excessive immune response forms in the damaged area. Thus, depending on the level of secretion of inflammatory environment factors, mesenchymal stem cells exhibit either pro-inflammatory or anti-inflammatory functions. Further study of immune processes in chronic non-communicable diseases of the nasal cavity will contribute to the emergence of new, more effective methods of treatment based on cell therapy.

Вступ. Стаття присвячена вдосконаленню методик ортогнатичної хірургії за допомогою застосування тривимірного цифрового планування, з метою підвищення точності хірургічних втручань для корекції трансверзального дефіциту верхньої щелепи. Метою дослідження є аналіз точності проведення ортогнатичних операцій з використанням тривимірного цифрового планування у пацієнтів з ТД ВЩ, які потребують хірургічно асистованого розширення піднебіння (SARME) на стадії прехірургічної ортодонтичної підготовки. Матеріали та методи. У дослідженні використовувалась вибірка з 50 пацієнтів із скелетними формами аномалій та деформацій щелеп, які проходили лікування за період з 2019 по 2023 роки. 50 пацієнтів з ТД ВЩ та сагітальними/вертикальними аномаліями прикусу були розділені на 2 групи: основна група (n=25): SARME з використанням дистрактора Smile distractor (Titamed, Бельгія) на етапі прехірургічної ортодонтичної підготовки та контрольна група (n=25): ТД ВЩ відсутній або скорегований раніше. В обох групах ортогнатичні операції проводились за повним цифровим протоколом з використанням даних 3D-комп’ютерної томографії (КТ) та віртуального планування. Використання тривимірного планування дозволило оптимізувати прехірургічну підготовку та визначити оптимальні параметри хірургічного втручання. Результати дослідження продемонстрували значне збільшення точності ортогнатичних операцій, зменшення ризику рецидивів та побічних ефектів із незначними відхиленнями від планованих показників. Авторами здійснено детальний аналіз ефективності застосування цифрового планування для забезпечення точності ортогнатичних операцій у пацієнтів з різними формами скелетних аномалій щелеп. Наукова новизна полягає у підтвердженні ефективності SARME як методики, що дозволяє оптимізувати прехірургічну підготовку та підвищити точність ортогнатичних операцій у пацієнтів з трансверзальним дефіцитом верхньої щелепи (ТД ВЩ). Встановлено, що використання дистрактору Smile distractor (Titamed, Бельгія) для розширення ВЩ дозволяє досягти високого рівня точності прогнозованості результату, що є значним досягненням у поліпшенні якості життя пацієнтів. Висновки підтверджують високу ефективність застосування цифрових технологій у ортогнатичній хірургії для пацієнтів з ТД ВЩ, що дозволяє забезпечити кращу прецизійність та прогнозованість результатів лікування, мінімізуючи ризик ускладнень. Обмеження дослідження включали негомогенність вихідних умов пацієнтів за скелетним класом, типом росту та наявністю відкритого або глибокого прикусу, що може вплинути на універсальність та точність отриманих результатів.
CO2 absorption using LIs functionalized with amino acids
Authors: Barbosa-Moreno Gabriela
Published: April 2024

A comparative study was conducted on the absorption of
carbon dioxide (CO2) using ionic liquids (ILs) based on
imidazole derivatives as cations and amino acids as anions
([BMI][AA] and [OMI][AA]). The synthesized ILs were
characterized using Fourier Transform Infrared
Spectroscopy, and absorption studies were conducted
using a pressurized batch system under stable pressure and
temperature conditions. Amino acids demonstrated an
enhancement in the absorption of this acidic gas when
compared to monoethanolamine, which is the most
commonly used commercial absorbent compound.
Debugging and programming a RISC-V processor, using the IEEE 1149.1 standard
Authors: Rico-García Paulina
Published: April 2024

RISC-V processors are an open source ISA (Instruction
Set Architecture), which means that anyone can design
and modify them to meet the specific objectives of any
development. Thanks to the flexibility it brings with it, it
is possible to add a debugging and programming logic unit
to this processor to get a real sense of how the processor
works, a unit that will be key to identifying errors during
the design of the processor, as well as errors that may
occur during the manufacturing process. This article
presents the methodology used to incorporate hardware
that allows the processor to be debugged, using the IEEE
1149.1 standard as a reference
Counseling and Tutoring, tools to reduce desertion at the TSU level
Authors: RODRÍGUEZ-VARGAS María De Jesús
Published: April 2024

Derived from the increase in dropout rates during the year
2020-2021 at the TSU level in Information Technology,
the implementation of strategies that effectively address
this problem is proposed. The most frequent causes in the
students who dropped out of the career were analyzed to
determine the elements to consider, these being the lack of
identification with the educational program and personal
problems. Counseling and tutoring strategies were
implemented by the teaching staff and complemented by
the support of external specialists in the different areas of
the curricular plan, as well as psycho-pedagogical support.
The results obtained are favorable by reducing the number
of dropouts from 15 to 1 in the next cycle, in addition to
strengthening soft skills in students. Additionally, a
projection of these strategies is displayed as part of a
didactic model for the reinforcement of technical and soft
skills in the university community
Determination of risk zones by thermal flow, generated by BLEVE to a tank with LP gas, using mathematical models and ALOHA® software
Authors: Torres-Valle José Bernardo
Published: April 2024

The objective of this research work was to determine the
risk areas for thermal radiation, generated by BLEVE and
fireball in a 13,000 L tank with LP gas, located in the
municipality of Nicolás Romero, State of Mexico, from
of mathematical models and the ALOHA® software, in
order to compare and analyze the results obtained. In
order to carry out the solution of this work, first the event
and hypothetical scenario in which the type of applicable
source was defined, which is BLEVE followed by
fireball, is judged, and later different data were
determined for the present study. Based on the above, the
corresponding modeling was carried out to determine the
risk zones of affectation by thermal radiation, the
dimension of the diameter and the duration of the
fireball. As a result, a comparative analysis was obtained
in which it was possible to observe and conclude that the
results obtained through mathematical models, in
general, present more conservative results, compared to
the modeling used by ALOHA®
Implementation of a unidirectional wireless communication for monitoring Physical variables
Authors: Perez García Víctor
Published: April 2024

This article describes the implementation of a peer-to-peer
unidirectional wireless communication between a
transmitter unit and a receiver unit, for monitoring
temperature and relative humidity (RH) within a
greenhouse of 10 m2 gothic type with a curved roof. The
transmitter unit consists of temperature and RH sensors,
and a wireless monitoring and control electronic board that
can transmit and receive information using the XBee S2C
module. The receiving unit is composed of a Graphical
User Interface (GUI) designed in NI LabVIEW, and an
XBee S2C module mounted on the SparkFun XBee
explorer dongle board. Within the wireless network, the
XBee module of the transmitting unit was configured as
the end device, while the XBee of the receiving unit was
configured as the coordinator. Monitoring tests were
carried out in the laboratory and inside the greenhouse, to
verify the proper functioning of wireless communication.
This work has inspired the future monitoring and control
of climate variables within the greenhouse, using a
wireless network with mesh topology
Sky-Maiden and World Mythology
Authors: Berezkin Yuri
Published: April 2024

Traditions that share the least number of motifs are located in continental Eurasia and Melanesia. African mythologies are poor and stand nearer to the Indo‑Pacific than to the Continental Eurasian pole. The Indo‑Pacific mythology preserved its African core. In Continental Eurasia a new set of motifs began to spread after the Late Glacial Maximum. Both sets of motifs were brought to the New World. The Indo-Pacific complex predominates in Latin, the Continental Eurasian one in North America. Sky‑maiden tales, largely unknown in Africa and Australia, emerged in the Indo-Pacific borderlands of Asia. Both in Southeast Asia and in Latin America different images of the magic wife coexist (different birds, sky-nymphs, etc.), stories are often integrated into the anthropogenic myths. More specialized Swan-maiden stories spread across Northern Eurasia after the Late Glacial Maximum. Only Khori‑Buryat versions are related to actual mythology. Swan‑maiden was brought to America late by the Eskimo.
Corps énergétique et danse
Authors: Villard Marie-Aline
Published: April 2024

Penser le « corps énergétique » et la danse revient à considérer cette réalité énergétique au sein du corps dansant, autant au niveau quantitatif que qualitatif. En danse, nous ne parlons pas exactement de « corps énergétique », mais principalement d’énergie déployée. Afin de comprendre le « corps énergétique » en danse, nous nous sommes intéressés à deux pratiques originales mettant en œuvre un jeu de question-réponse énergétique : le contact improvisation et le vol chorégraphique. Le corps énergétique apparaît au fur et à mesure de la réflexion comme une métaphore désignant une triade nécessaire au déploiement d’un seul système, et c’est cette même triade que nous rencontrons à chaque fois que nous appréhendons la complexité du corps dansant.
De l’importance de l’imaginaire dans le dialogue « science-société »
Authors: Chifflet Stéphanie
Published: April 2024

Les enjeux des sciences et des techniques ne peuvent être saisis dans toute leur complexité sans une prise en compte préalable du rôle de l’imaginaire dans la pensée de l’homme et dans son être-au-monde. Le rapport de l’homme aux savoirs scientifiques et techniques est composé d’images et de récits mythiques plus ou moins conscients. Débattre de l’orientation que nous souhaitons donner aux recherches et aux innovations scientifiques nécessite de considérer sérieusement l’irrationalité humaine. C’est en saisissant cette logique autre (l’« alogique »), les rêveries parfois indicibles, les peurs persistantes, que le dialogue « science-société » pourra être ouvert et constructif.
L’analyse contrastive : contours et limites d’une approche mythocritique confrontant le Genji Monogatari de Murasaki Shikibu et les Lais de Marie de France
Authors: Bruno-Meylan Stéphanie
Published: April 2024

Dans le cadre de notre thèse, nous avons confronté les Lais de Marie de France datant du xiie siècle qui présentent la particularité alors inédite d’avoir pour auteur une femme et le Genji Monogatari de Murasaki Shikibu (une femme également), écrit au xie siècle au Japon, qui fait aussi figure d’exception dans un paysage scriptural majoritairement masculin, a fortiori pour une œuvre d’une telle ampleur. Le rapprochement entre les deux œuvres était avant tout motivé par une thématique de fond, l’imaginaire féminin, déployé dans deux cultures géographiquement et sociologiquement éloignées, cependant immergées dans un milieu élitiste, celui de la Cour. Ce choix s’inscrivait surtout dans la perspective d’une approche mythocritique plutôt que strictement littéraire, dont l’intérêt se situait en deçà du cadre du texte, puisqu’il puisait dans la mythologie fondatrice des deux cultures, source de l’émergence d’un imaginaire féminin à des époques chiches de féminité. Or, cette analyse, que nous avons qualifiée de contrastive, a permis l’ouverture de la réflexion sur d’autres perspectives que seul autorisait un tel rapprochement ; elle a également cherché à distinguer, parmi les motifs communs aux deux textes, ceux qui relevaient d’une universalité (contextuelle) de ceux qui relevaient d’une commune origine eurasiatique. La réflexion était axée sur la notion d’altérité selon une acception très large mais concentrée sur la représentation par l’imaginaire féminin de l’Autre sexe et d’un Ailleurs avant tout textuel et narratif.
La couronne et la sépulture, ou la naissance du culte de saint Adalbert de Prague en Pologne médiévale
Authors: Salmon-Siama Monika
Published: April 2024

Cet article a pour objectif de présenter, en se basant sur l’exemple de la naissance du culte de saint Adalbert, évêque de Prague, comment le mythe hagiographique évolue dans le paysage idéologique et culturel de la Pologne aux alentours de l’an mil. À travers la mise en relief de plusieurs événements symboliques qui marquent la reconnaissance officielle de la sainteté du martyr, décapité en Prusse en 997, il est question de s’interroger sur l’évolution de l’imaginaire religieux à cette époque d’acculturation chrétienne, afin de comprendre pourquoi le patronage dynastique et patriotique a été attribué à saint Adalbert en Pologne médiévale.
De quelques nombres dans la tradition celtique
Authors: Jouët Philippe
Published: April 2024

Pour expliquer les nombres et leurs occurrences dans la tradition celtique (mythes, représentations, realia), plutôt que de les relier dans le cadre de la numérologie ou de leur donner a priori un sens, il faut analyser l’ensemble du contexte dans lequel ils apparaissent. La plupart de ces nombres sont profondément reliés aux saisons cosmologiques, aux modèles cycliques, et ont des valeurs analogiques et métaphoriques dans plusieurs champs (théories de la sagesse, de la guerre, du corps politique). Ils peuvent être compris comme le fruit d’expériences héritées de la culture indo-européenne, et s’inscrire dans une périodisation à déterminer. Relèvent de cette conception, les Jumeaux divins, les trois cieux, les trois fonctions, le voyage dans l’autre monde, l’organisation quaternaire ou quinaire des lieux. Cet article traite donc des occurrences des nombres en lien avec l’année, conçue comme une image rythmique de la puissance.
