Authors: Ridha Safa Riyadh , Solagh Hussam Numan 
Published: February 2025

The current work aims to study the effect of an inclined magnetohydro dynamics peristaltic transport of a non-Newtonian hyperbolic tangent fluid in a non-uniform channel via porous medium. The nonlinear governing equations regarding hyperbolic tangent fluid have been studied and solved analytically with the use of a regular perturbation approach under considerations of a long wavelength as well as low Reynolds number. All computational results are also discussed graphically using the MATHEMATICA program. The mathematical expressions for axial velocity and stream functions have been derived analytically. Different physical parameters have been shown graphically and discussed it's effect. It is established that increasing the Hartmann number and the parameter of porosity will increase the velocity and the quantity of boluses. While the size of boluses decreases by increasing the magnetic field inclination angle. Moreover, Some mathematical and engineering aspects of non-Newtonian fluids are investigated in the current analysis.

Sustainability disclosure is entering a new era with the enhanced integration of sustainability and climate-related practices into corporate business and financial models through the newly established IFRS S1 and S2 Standards, which the International Sustainability Standards Board introduced in mid-2023 and take effect with implementation set for the 2024 reporting year. With focusing on companies listed in the ESG Quality 45 IDX KEHATI Index, this study will examines whether firm values can be influenced by sustainability and climate-related core content disclosures under these Standards. The research employs a quantitative model using Random Effects Model with multiple linear regression equations. The results reveal that firm value is significant-negatively influenced by governance and strategy disclosures. Risk management disclosures can positively influence the firm value. However, firm value can not be influenced by metrics and targets disclosures. The research findings suggest that companies must strengthen their knowledge base and competencies in aligning these four core contents to achieve comprehensive and transparent sustainability disclosure.

Published: February 2025

Background
Internal carotid artery (ICA) injury is a rare but severe complication of transsphenoidal surgery.

Case Description
A 69-year-old woman presented with progressive visual disturbance secondary to pituitary adenoma. The patient underwent subtotal tumor resection through endoscopic transsphenoidal surgery. The residual tumor in the cavernous sinus gradually enlarged over the next 3 years. During a second surgical intervention, an inadvertent scratch, with the worn-out tip of the micro-suction device, on the partially calcified medial wall of the C4 segment resulted in ICA rupture, leading to uncontrollable hemorrhage. After provisional hemostasis, the patient was transported to the angiography suite, where an irregularly shaped leak of contrast on the medial aspect of C4. A stent-assisted coil embolization was successfully performed, resulting in complete aneurysm isolation. The patient underwent revisional surgery on postoperative day (POD) 14, in which the coils exposed from the ICA laceration were covered with fascia lata, muscle, and surgical glue. After a lumboperitoneal shunt placement for progressive hydrocephalus, the patient was discharged on POD 82 without focal neurological deficits.

Conclusion
During transsphenoidal surgery, ICA injury can result from inadvertent manipulation using a micro-suction device. Careful manipulation and conservative resection followed by stereotactic radiosurgery may be a valid strategy for managing pituitary adenomas invading the cavernous sinus.

Published: February 2025

Background
Highly migrated cervical disc herniations are rare, and the optimal surgical approach remains uncertain. When located in the median or paramedian position, anterior cervical discectomy and fusion or anterior cervical corpectomy and fusion are preferentially selected, whereas posterior approaches are often considered for cases with radiculopathy.

Case Description
A 40-year-old woman presented with right C6 radicular symptoms without any specific triggering event. She initially experienced symptom relief through medication and an ultrasound-guided nerve block 4 years previously. The symptoms recurred 2 months before presentation and did not improve with conservative treatment. Magnetic resonance imaging revealed a paramedian herniation on the right side, migrating downward from the C5/6-disc level to the inferior border of the pedicle. Posterior endoscopic cervical discectomy (PECD) with partial pediculotomy was performed under general anesthesia with transcranial motor-evoked potential monitoring. The operative time was 56 min. The patient experienced immediate symptom relief, mobilized 3 h postoperatively, and was discharged the following day.

Conclusion
PECD with partial pediculotomy is a minimally invasive and effective option for treating highly down-migrated cervical disc herniation, offering reduced tissue disruption, faster recovery, and excellent clinical outcomes.

Published: February 2025

Description of the subject. Borassus akeassii Bayton, Ouédr. & Guinko is a multi-purpose species cultivated by various ethnic groups in southwestern Burkina Faso. These palm’s populations are undergoing significant transformations due to human activities. Objectives. This study aims to explore the structural characteristics and population dynamics of the palm tree, B. akeassii, in southwestern Burkina Faso, particularly in the Turka region. Method. The study is based on ethnographic surveys conducted among local populations, combined with ecological data. Results. The results highlight a predominance of juvenile palms, a balanced sex ratio among adult palms, generally satisfactory palm population health, and low mortality among adult palms due to controlled exploitation. Palm stands are currently affected by profound socio-economic changes. This has results in a loss of the social and economic value of the palm tree and the abandonment of traditional practices. Consequently, the abundance and condition of palm stands have deteriorated. Conclusions. The decisive factor in the dynamics of the palm stands appears to be the decrease in the social and economic profitability of the plant. The ancestral values and connections between B. akeassii palm and the local populations are currently being deconstructed. Borassus akeassii being cultivated in the region, the local population’s lack of interest in this plant and its products will lead to its replacement by other crops in areas reserved for agricultural activities.

Обоснован способ классификации поверхностных водных объектов, относящихся к одному бассейну, путем многомерной нейросетевой кластеризации с нечеткими элементами и экспертным оцениванием. Исследовались массивы данных по значениям гидрохимических показателей, полученные в системе государственного экологического мониторинга поверхностных вод Волжско-Камского бассейна в период 2014-2021 гг. Кластеризация имеющихся наборов измеренных гидрохимических показателей водных объектов проведена с применением нейронных сетей Кохонена, преимуществом которых является способность к дообучению при поступлении новых данных, и выделение неоднородных групп с заданной степенью точности с применением алгоритма, подобного алгоритму k-средних. Выделено 6 классов поверхностных вод, охватывающих всю изменчивость фонового гидрохимического состава вод Волжско-Камского бассейна, которым даны качественные оценки и методом факторного анализа выделены классифицирующие показатели. Статистически определены пороговые значения классифицирующих показателей. Предложен алгоритм отнесения произвольной пробы воды к одному из выделенных классов поверхностных вод.
The method of classification of surface water bodies belonging to the same basin by multidimensional neural network clustering with fuzzy elements and expert assessment was substantiated. The data sets on the values of hydrochemical indicators obtained in the system of state environmental monitoring of .surface waters of the Volga-Kama basin in the period 2014-2021 were studied. Clustering of the available sets of measured hydrochemical indicators of water bodies was carried out using Kohonen neural networks, the advantage of which is the ability to retrain when new data arrive, and the selection of heterogeneous groups with a given degree of accuracy using an algorithm similar to the k-means algorithm. Six classes of surface waters covering the whole variability of the background hydrochemical composition of the Volga-Kama basin waters were identified, qualitative assessments were given to them and classifying indicators were identified by the factor analysis method. The threshold values of classifying indicators were statistically determined. An algorithmfor assigning an arbitrary water sample to one of the selected classes of surface waters is proposed.
ИСПОЛЬЗОВАНИЕ МНОГОТОННАЖНОГО НЕФТЯНОГО ШЛАМА КАК ВТОРИЧНОЕ СЫРЬЕ В ПРОИЗВОДСТВЕ ЛЕГКОВЕСНОГО КИРПИЧА НА ОСНОВЕ БЕНТОНИТОВОЙ ГЛИНЫ

Нефтешламы имеют повышенные теплотворные способности (Q > 2500 ккал/кг) и содержания углерода (С > 10 %), следовательно, такие отходы имеют возможность использоваться не только как отощители, но и в роли выгорающих добавок, которые в процессе выгорания создают пористость для формирования легковесного кирпича. В представленной работе зафиксировано, что, принимая в расчет высокую чувствительность не только к сушке, но к обжигу бентонитовой глины при ее стопроцентном содержание в керамическом кирпиче после термообработке на нем появляются трещины, что неизбежно требует присутствие в составах изделий ото-щитель. На платформе бентонитовой глины, используемой в качестве пластичного сырья и крупнотоннажного отхода нефтяной промышленности - нефтяного шлама (нефтешлам), утилизируемого как вторичное сырье в качестве отощителя и выгорающей добавки получен керамический легковесный кирпич. Оптимальным составом для производства легковесного кирпича является состав, содержащий 50 % нефтяного шлама, полученный кирпич по коэффициенту теплопроводности относится к группе высокой эффективности.
Oil .sludge has increased calorific value (Q > 2500 kcal / kg) and carbon content (C > 10 %), therefore, such waste can be used not only as thinners, but also as burnout additives, which in the process of burning create porosity for the formation of lightweight bricks. In the presented work, it is recorded that, considering the high sensitivity not only to drying, but to roasting bentonite clay with its one hundred percent content in ceramic bricks, cracks appear on it after heat treatment, which inevitably requires the presence of a cleaner in the compositions ofproducts. A ceramic lightweight brick was obtained on the platform of bentonite clay used as plastic raw materials and large-tonnage waste of the oil industry - oil sludge (oil sludge), disposed of as secondary raw materials as a thinner and burnout additive. The optimal composition for the production of lightweight bricks is a composition containing 50 % oil sludge, the resulting brick belongs to the high efficiency group according to the coefficient of thermal conductivity.

Одномоментно в мировом воздушном пространстве находится несколько тысяч самолетов, и ежедневно в мире возникают авиационные события, связанные с нарушением безопасности. В мировом парке активных самолетов наибольшее количество моделей Airbus и Boeing. В работе поставлена гипотеза - чем больше самолетов одного типа в мировом авиапарке, тем больше авиационных событий происходит на них. Для проверки гипотезы в работе проанализированы авиационные события на самолетах за 2023 год в мире по данным открытого источника (Telegram канал «A viaincident»). Анализируемыми параметрами являлись дата события, тип авиационного судна, маршрут следования, тип авиационного события. Результаты проведенного анализа показали, что наибольшее количество авиационных событий произошло на самолетах Boeing и Airbus. Детальный анализ авиационных событий по моделям самолетов выявил лидеров: Boeing 737 и Airbus 320. К основным причинам авиационных событий отнесены столкновение самолета с птицей («bird strike») и отказ двигателя самолета. Распределение события «bird strike» по месяцам связано с сезоном миграции птиц. Полученные в работе результаты за 2023 год подтвердили поставленную гипотезу.
There are several thousand aircraft in the global airspace at one time and aviation events related to safety violations occur daily in the world. The world fleet of active aircraft has the largest number of Airbus and Boeing models. The paper hypothesizes that the more aircraft of the same type in the world fleet, the more aviation events occur on them. To test the hypothesis, the paper analyzes aviation events on aircrafts in 2023 in the world according to open source data (Telegram channel «Aviaincident»). The analyzed parameters were the date of the event, the type of aircraft, the route, and the type of aviation event. The results of the analysis showed that the largest number of aviation events occurred on Boeing and Airbus aircraft. A detailed analysis of aviation events by aircraft models revealed the leaders: Boeing 737 and Airbus 320. The main causes of aviation events include the collision of an aircraft with a bird («bird strike») and the failure of the aircraft engine. The distribution of the «bird strike» event by month is related to the bird migration season. The results obtained in the work for 2023 confirmed the hypothesis.

Abstract
The article presents research focused on design, testing and evaluation of the Artificial Intelligence (AI) algorithms dedicated for Virtual Player (VP/bot) embedded in the Production Management Training Platform (TP). The innovative software enables complex teaching process in form of didactic games. The purpose of the study is to eliminate limitations of the prototype VP’s algorithmic structure which was primarily implemented in the Platform. The study comprise measurements aimed at comparing effectiveness and efficiency of the existing solution with the capabilities of the newly developed VP’s logic. The overview of the algorithmic concepts available for VPs in serious games was made indicating elements useful for the purpose of the analysed system. Considering drawbacks of the original bot’s engine architecture, the upgraded version was elaborated and tested in the simplified version of the game. The results of the verification show to prove dominance of the AI solution with Machine Learning over the existing hybrid approach. The training, evaluation and recruitment games offered by the Platform could successfully fill in the gap identified in the new paradigm of education for Industry 4.0. It assures teaching of multidiscipline knowledge as well as practical skills training in the competitive environment altogether with thorough evaluation procedure. The appropriate VP’s logic increases flexibility of the didactic game and enables to customize the learning process which is crucial for the successful education process aided with gaming tools.
Effect of Fe and Mn on Corrosion Resistance of Recycled Self-hardening AlZn10Si8Mg Alloy

Abstract
Recycled aluminium alloys are a highly valued alternative for manufacturers, particularly in the automotive and aerospace industries, due to increasing demands on the environmental performance and sustainability of the industry. Self-hardening aluminium alloys, which achieve the required mechanical properties without heat treatment, enable the emissions generated by production to be reduced even further. In addition to an advantageous strength-to-weight ratio and excellent machinability, corrosion resistance in a variety of environments is also important in most applications of aluminium alloys. Repeated recycling cycles negatively influence the quality of aluminium because of an increase in iron content, which is considered an impurity. This is due to the formation of intermetallic phases which negatively affect the mechanical, fatigue and corrosion properties. In this paper, the effect of Fe and Mn on the microstructure and corrosion resistance of self-hardening recycled AlZn10Si8Mg alloy was investigated using the AUDI test, atmospheric long-terming test and 3.5% NaCl solution test. The corrosion mechanism was subsequently determined by sectioning the samples. Alloy A with the lowest iron content exhibited the best corrosion behaviour, as it was subjected to only localised forms of corrosion even in the aggressive environment of the AUDI test. In this environment, the other alloys were attacked by general corrosion of the entire surface. Manganese alloying caused a subtle improvement in the corrosion resistance of alloy D but was limited by the high porosity. The eutectic and intermetallic phases corroded the most, while the alpha phase was more resistant.

Abstract
The study focuses on the design and modernization of a feed mixer and demonstrates the impact of what might seem like a non-primary machine in the technological line for producing vitamin-enriched salt lick blocks (SLB) on the quality of the final product, the salt block. Furthermore, it examines the effect of SLBs themselves on animal growth and productivity, including increased milk yields and weight gain. Original recipes and ingredients of the feed salt mixture with their granulometric composition, moisture content, and mass fraction in the composition of the vitamin-enriched salt premix lick block are provided. The design of the mixing shaft is shown, and the operation of the modernized mixer is described. Experimental equipment from the technological line for the production of premix lick blocks is presented. The results of statistical regression analysis are given, adequately describing the working process of the mixer and allowing the calculation of the specific productivity of the new mixer, energy consumption, and mixing homogeneity within the selected intervals of variation of input factors. The component composition ratios of the SBL were found, which allowed achieving maximum specific productivity and homogeneity, as well as minimum energy consumption in a wide range of input parameters of the mixing process in the new mixer. The effect of the final product, vitamin-enriched salt premix lick blocks, on the growth and productivity of animals was studied.
GOVERNANÇA DE DADOS NA CONSTRUÇÃO DAS CIDADES INTELIGENTES:
Authors: Juliano Silva Daniela 
Published: February 2025

Na sociedade da informação, as denominadas “cidades inteligentes” são o chamativo ideal para rotular essas urbes como centros de inovação, sob a bandeira de uma gestão democrática e sustentável. Essa “propaganda” atrai investidores e promove a sensação de que tais cidades são inclusivas e cada vez mais dialógicas quanto às necessidades de seus moradores. As Tecnologias de Informação e Comunicação (TICs) têm no setor público seu grande incentivador e usuário, sendo instrumentos indispensáveis para uma maior efetividade na prestação dos serviços públicos e na construção de uma gestão mais participativa. Diante de um universo de probabilidades, muitos desafios emergem e impõem reflexões a respeito de sua padronização, segurança e regulação. O presente artigo pretende refletir acerca dos usos das novas tecnologias na construção dessas cidades, partindo-se de um método dedutivo, tendo como técnica de pesquisa, o referencial bibliográfico presente nas lições de Morozov e Bria (2019) e Reia (2021), bem como uma metodologia exploratória, com um olhar sobre a experiência do Município de Niterói/RJ, ranqueada como a quinta cidade mais inteligente do Brasil.
Formulating problems in psycho-social rehabilitation: Narrative activity within the boundaries of an institutional framework
Authors: Piccini Chiara , Carassa Antonella 
Published: February 2025

This article presents a study on team talk in psychosocial rehabilitation with reference to collective decision making. It focuses on problem formulation processes that occur during weekly team meetings in a Swiss organization providing psychosocial rehabilitation to chronic mental health patients. The corpus of team meetings (34 hours of recorded talk) was analyzed along three narrative dimensions: participation framework, timeline organization and forms of evaluation. The analysis was supported by ethnographic information (field notes collected during participant observation over ten months), in order to access the local conception and organization of rehabilitation work, which is repeatedly referred to and reshaped through discourse. The discursive practices identified show that team members learn to formulate problems in a way that allows them to identify and plan interventions in line with their rehabilitation model and the actual opportunities they have. Further, the role-related forms of participation highlight how different professionals contribute to the problem formulation in specific ways. In sum, the interaction turns out to be strongly centralized around the role of a meeting coordinator, who is able to enhance the participation of the other team members and to build institutional narratives on the basis of individual contributions, carrying out discursive work that can be metaphorically described as the weaving and knotting threads that make up a tapestry.
