Analysis of Casting Defects, Tensile Strength, and Hardness of AlSi Alloy Castings from Sand Casting Method with Bangkalan Local Clay Binder Variations
Authors: Muhtarom Imam , Rahdiyanta Dwi
Published: June 2024

This study aims to determine the casting defects, tensile strength, and hardness of the AlSi alloy obtained in the Sand Casting method with Bangkalan local clay as a binder. This experimental research uses the one-shot case study method in which a group of samples is given treatment. Furthermore, the research results were analyzed and described descriptively. This study uses three independent variables and three dependent variables. The independent variable is the local Bangkalan clay binder with varying percentages of 6%, 9%, and 12%, while the dependent variable is casting defects, tensile strength, and metal hardness. The research results show that the lowest casting defects are obtained on the AlSi metal surface, with a variation in the percentage of the binder of 12% with a total of 76 hole defects and 80-grain structure defects. At the same time, the highest tensile strength value is obtained in AlSi metal with a binder variation of 12% with a value of 11.188 kgf/mm². The highest hardness value is also obtained in AlSi metal, with a binder variation of 12% with a value of 131.9 HV. This study concludes that using local Bangkalan clay binder in 12% is the best sand mold binder variation compared to 6% and 9% binder variations.

This study applied a subtractive genomics approach to identify a potential drug target in the Porphyromonas gingivalis strain (ATCC BAA-308/W83). The aim was to characterize the whole proteome and hypothetical proteins (HPs) through structural, functional, and pathway predictions. The proteome was systematically reduced to identify essential proteins (EPs), non-homologous proteins (NHPs), and non-paralogous proteins (NPPs) while excluding those that were similar to the human proteome. Out of 1,836 proteins, the cluster database at high identity with tolerance algorithm identified 36 sequences as paralogous, having 80% identity. The resulting 1,827 proteins were compared to the human proteome using BLASTp (e-value 10−3), resulting in 1,427 NHPs. These were then aligned with the DEG database using BLASTp (e-value of 10−5), identifying 396 NHPs essential for pathogen survival. CELLO predicted the sub-cellular localization, and KEGG Automated Annotation Server identified potential metabolic pathways using a BLASTp similarity search of NHPs and EPs against the infrequently updated KEGG database. A total of 79 HPs essential for P. gingivalis were selected, and their molecular weights were determined. HPs were screened for metabolic pathway prediction, and the 3D structures of the proposed HPs were determined using homology modeling, and validation was performed. Only one HP (putative arginine deiminase) was qualified and found to be involved in the arginine and proline metabolic pathway.

Published: June 2024

It has been suggested that, prior to a saccade, visual neurons predictively respond to stimuli that will fall in their receptive fields after completion of the saccade. This saccadic remapping process is thought to compensate for the shift of the visual world across the retina caused by eye movements. To map the timing of this predictive process in the brain, we recorded neural activity using electroencephalography during a saccade task. Human participants (male and female) made saccades between two fixation points while covertly attending to oriented gratings briefly presented at various locations on the screen. Data recorded during trials in which participants maintained fixation were used to train classifiers on stimuli in different positions. Subsequently, data collected during saccade trials were used to test for the presence of remapped stimulus information at the post-saccadic retinotopic location in the peri-saccadic period, providing unique insight into when remapped information becomes available. We found that the stimulus could be decoded at the remapped location ∼180 ms post-stimulus onset, but only when the stimulus was presented 100–200 ms before saccade onset. Within this range, we found that the timing of remapping was dictated by stimulus onset rather than saccade onset. We conclude that presenting the stimulus immediately before the saccade allows for optimal integration of the corollary discharge signal with the incoming peripheral visual information, resulting in a remapping of activation to the relevant post-saccadic retinotopic neurons.

Для центральной части Нижнеамурской провинции выполнен анализ цифровой модели рельефа (SRTM03). По комплексу признаков выделена Лимури-Амгуньская кольцевая структура, где расположены золоторудные Пильда-Лимурийский и Херпучи-Вьюнский районы и Албазинский узел, в пределах которых известны как крупные промышленные месторождения золота, так и большое количество мелких месторождений и рудопроявлений. Проанализированы особенности распределения линейных и кольцевых элементов рельефа, дана их геологическая интерпретация и показано пространственное соотношение с ними месторождений и рудопроявлений золота. Показана связь морфологической выраженности кольцевой структуры с глубинным строением региона; структура имеет магматогенную природу, характеризуется высокой концентрацией интрузивных тел. Согласно литературным данным по возрасту и составу магматических комплексов региона, образование кольцевой структуры связано с процессами новообразования и преобразования земной коры и верхней мантии в конце позднего мела-начале палеоцена в надсубдукционной геодинамической обстановке.

The digital elevation model (SRTM03) of the central part of the Lower Amur province is analyzed. The Limuri-Amgun ring structure is identified on the basis of a set of features, and it is also the location of the Pilda-Limuri and Kherpuchin-V’yunsky gold-ore regions, as well as the Albazino deposit, known for large industrial gold deposits and many small deposits and ore occurrences. The distribution of linear and ring elements of the relief is analyzed and geologically interpreted, and its spatial relationship with gold deposits and ore occurrences is shown. The relationship between the morphological severity of the ring structure and the deep structure of the region is shown. It is revealed that the structure is magmatic and characterized by a high concentration of intrusive bodies. According to the reference data on the age and composition of the igneous complexes of the region, the formation of the ring structure is associated with the processes of neoformation and transformation of the Earth’s crust and upper mantle during the end of the Late Cretaceous and the beginning of the Paleocene in a suprasubduction geodynamic setting.

Authors: Balvinska M. S. , Fait V. I.
Published: June 2024

Aim. To investigate the polymorphism of microsatellite loci of the 5HL chromosome of barley, including those which
are location in the area of LT-resistance key genes and close to them, to determine and evaluate the frequence of
microsatellite alleles in the genetic material of autumn-sown barley of different origin. Methods. The isolation of
genomic DNA, microsatellite analysis, PCR amplification, gel electrophoresis, and statistical analysis. We studied 46
barley genotypes of different origin, including 33 winter barley varieties, and 13 varieties of alternative (facultative)
growth habit; among these 46 barley genotypes, 21 varieties were developed by PBGI-NCSCI, 25 – of other origin,
including 21 from the countries of Central Europe (Czech Republic/CZ – 2; Grabe, Luran; Germany/DE – 4: Skarpia,
Majbrit, Сinderella, Highlight), Western Europe (France/FR – 1: Anzhelika; the Netherlands/NL – 1: Gerlach) and
Eastern Europe (NGC named after P.P. Lukianenko/RU – 13, 11 winter varieties: Derzhavnyi, Espada, Zhavoronok,
Kondrat, Kumach, Meteor, Metaksa, Mikhailo, Platon, Tigr, Khutorok, and 2 winter-and-spring varieties: Putnik,
Timofei) and 4 Western-Asian varieties (Syria/SYR – 4: Pamir013/Sonata, Pamir065/Pamir149, CWB-117-77-97,
ROHO). Results. The allelic polymorphism was studied by 14 microsatellite loci of the 5HL chromosome of barley,
including those in the area of genes Fr-H1, Fr-H2 and close to these regions, the distribution of the identified micro-
satellite alleles was studied along with their frequencies and genetic diversity in the sampling of 46 collection varieties
of autumn-sown barley of different origin. Among the investigated microsatellite areas of the 5HL chromosome of
barley, only 50 % of loci in the selected samples of varieties were found to be polymorphic. These were microsatellite
loci Bmag0760, GMS061, Bmag0337, UMB702, Bmag0323, Bmag0223, and Bmag0222. We found the dominating
alleles and those with reliably lower frequency, and the alleles specific only for some regions. The estimated values
of the polymorphism information content (PIC) for the investigated polymorphic microsatellite loci varied between
0.29 (UMB702) – 0.77 (Bmag0223). The diversity index was 0.54 on average. Conclusions. The results of the study
demonstrated moderate allelic diversity of the investigated microsatellite loci of the 5HL chromosome of barley,
which indicates the presence of potential genetic variability of some loci, the possibility of applying them in further
studies on determining the effects of specific alleles of each locus and their associations with required economically
valuable traits of barley, including resistance to low temperatures (LT-resistance). The potential of polymorphic alleles
as markers of frost-resistance traits of autumn-sown barley genotypes is discussed.
Reduction of risk of choosing the optimal ventilation mode for the period of elimination of exogenous fire

The time from the occurrence of an exogenous fire in a mine to its complete elimination can be conventionally divided into two periods: the operational time of the emergency elimination plan and the period of intensive fire extinguishing or fire cell isolation. In the first period, there is a significant number of working people in the mine, so the emergency ventilation mode must first of all ensure safe conditions for their evacuation. The issue of choosing an emergency ventilation mode in the mine ventilation network for use during the operational time of the emergency liquidation plan has been studied in sufficient detail. At the second stage of fire development, the ventilation mode should ensure the removal of combustion products by the shortest paths to the exit jet or to the workings where there are no people; to provide fresh air supply, normal temperature and minimal smoke in the areas where mining rescue works are carried out; reduce the intensity of fire development; to prevent overturning of ventilation jets in inclined workings. Among the listed requirements, there are both those that satisfy and those that contradict the criterion of the first period. Therefore, in a number of cases, during the liquidation of developed fires, it is necessary to change the ventilation mode to ensure the fulfillment of the considered conditions. A method of transition from the mode of the first period to the mode of the second is proposed, which consists in determining the list of ventilation modes that are subject to optimization. For each of them, workings are defined, in which it is possible to overturn the ventilation jet. Due to the minimization of their number, it is possible to prevent the spread of a fire zone gassed with gaseous products (that is, its minimization) and to complicate the conditions of conducting mine rescue operations. For this purpose, the theory of interrelationship of aerodynamic parameters of mine workings is used, which simplifies multi-fan ventilation calculations. The described algorithm only seems somewhat cumbersome, since it is known from practice that in the area of action of intense thermal depression of the fire cell, several loosely connected workings cannot be located far from each other, with a possible spreading of the ventilation jet. Thus, by achieving the condition of non- spreading of the ventilation jet for one of the working, it is possible to indirectly solve the problem for a number of other workings, incidental to it, which significantly reduces the complexity of the calculation process. Keywords: exogenous fire, emergency ventilation mode, thermal depression, interrelationship of aerodynamic parameters.

Published: June 2024

Aim. The aim was to study motivation functions and the psycho-emotional reaction to participation in volunteering in Polish and Ukrainian volunteers who assisted Ukrainian refugees at the beginning of the war in Ukraine in 2022.
Methods. For the empirical study of volunteers, the team of authors developed the questionnaire. The Volunteer Functions Inventory VFI and the Depression Anxiety Stress Scales DASS were used. The significance of the differences between the mean results of the measured variables in the Polish and Ukrainian samples was tested using the Student's t-test. Volunteers' expectations of volunteer leaders were tested by analysing responses to the open exploratory question.
Results. The article reveals similarities and significant differences between Polish and Ukrainian volunteers in their motives and psycho-emotional reactions to volunteering. A common motive for both samples is that they are not helping for the sake of their professional careers. Ukrainian volunteers had higher rates of protective, religious, and social motivation functions of volunteering. Polish volunteers had higher rates of motivation based on understanding and empowerment opportunities. Ukrainian volunteers scored higher than Polish volunteers on the depression, anxiety, and stress scales. Volunteers' motivation expectations of leaders indicate the importance for volunteers of leaders' adherence to values, openness of intentions and actions, and attentiveness to volunteers' difficulties.
Conclusion. The survey results can be used in psychological training for volunteers, in planning the activities of volunteer leaders, and in developing new methods for studying volunteer motivation.

Authors: Duangmanee Katematu , Waluyo Budi
Published: June 2024

Aim. Despite the popularity of Chinese foreign language teaching in schools worldwide, it is still little known how culturally local schools manage their Chinese teaching and learning. To address this gap, this study examined the pedagogical strategies and practices of Chinese as a Foreign Language (CFL) instruction in Thai secondary education, addressing the insufficient exploration of CFL educational undertakings beyond China's borders.
Methods. A narrative inquiry approach with interviews was employed. The sample included 34 school principals (11.8% female, 88.2% male), whose insights shed light on the cardinal aspects of CFL instruction and learning.
Results. The outcomes revealed essential elements shaping CFL pedagogy in culturally local schools in Thailand, including curricular considerations, collaboration through knowledge-sharing platforms and cultural events, teaching methodologies with teacher preparation and native-speaking instructors, learning activities inside and outside the classroom, and school-wide educational initiatives.
Conclusion. Overall, the findings contribute to the understanding of CFL education in Thailand and offer potential avenues for future research and pedagogical enhancement.

Published: June 2024

Aim: The study aims to analyze the climate factors in inclusive classes in motivating students with special needs to increase their academic achievements and improve social behaviors. Through a qualitative methodology, the study investigated several dimensions of supportive and open classroom climate on their impact on the performance of students with special needs in inclusive classrooms. Through the suggestions that this study offers, the close relationship that the supportive climate has in the motivation of students in the classroom, especially when different techniques of group activities are developed can be easily seen.
Method: For the realization of this study, ninety-two (92) students/teachers of the "Teachers in Primary Education" program of the second cycle of studies at "Aleksander Moisiu" University in Durres were included and were divided into four (4) focus groups. At the same time, semi-structured interviews were conducted with twenty-one (21) primary education teachers (grades 1-5) in three schools in the Municipality of Durres.
Results: The findings of the study highlight that collaborative climate factors in inclusive classrooms influence and motivate students with special needs. Several issues related to students' motivation have been identified, specifically: their motivation increases during group work, their motivation increases in project-based learning, and their motivation increases in the reinforcement of hard skills they bring to teaching supported by ICT.
Conclusion: Students and teachers also reported that all these beliefs and attitudes directly affect the performance of students with special needs and therefore their achievements. Teachers emphasize that students with special needs are more involved in group work, and some of the benefits that students with special needs have, are: improved communication and interaction by strengthening cooperation and self-efficacy. On the other hand, some of the benefits of project work that parents highlighted are: that children become more social; lasting friendships develop; self-esteem increases; and everyone's values and abilities stand out.

Changes in air permeability of restrained expansive concrete under drying condition: contribution of expansive strain
Authors: Wijaya Adhitya Leonard , Nakarai Kenichiro
Published: June 2024

Restraining the expansion of expansive concrete with embedded rebars can exert chemical prestressing, which may affect the durability of concrete structures. This study aims to investigate the durability performance of expansive concrete by understanding the mechanism of air permeability changes while considering the variations in reinforcement arrangements and concrete dimensions. The Torrent’s air permeability test was used to non-destructively evaluate the disparity in air permeability changes of expansive and normal concrete during the drying processes from 28 to 182 days. Additionally, expansive strain changes were continuously monitored to investigate chemical prestress. The experimental test results suggest the immense effect of the change in expansive strain on the air permeability of concrete. This study proposes that the change in microstructure owing to the loss of expansive strain may cause an increase in air permeability. The loss of expansive strain is a distinguished feature that differentiates the mechanism of air permeability changes in expansive and normal concrete. These findings suggest the possible improvement in the durability performance of expansive concrete in cases where the loss of its expansive strain can be controlled.
« Rest in Peace » (R.I.P.) : Faire et dire son deuil dans le monde numérique
Authors: Dilmaç Julie Alev
Published: June 2024

De nombreux auteurs des sciences sociales ont souligné la disparition de la mort dans les discours quotidiens ainsi que des rites qui l’accompagnent. Ce déni et refoulement seraient en partie dus aux nouvelles conjonctures de la société contemporaine. Cependant, aujourd’hui, on observe l’émergence de nouvelles manières de communiquer son deuil et de communier avec les autres en vue de commémorer les disparus, et plus particulièrement dans l’espace numérique. Dans cet article, il s’agit d’évoquer ces nouveaux dispositifs qui permettent de « faire » et de « dire » le deuil sur les réseaux sociaux. Nous porterons une attention particulière à l’emploi généralisé du terme « R.I.P. » (requiescat in pax ou plus communément « Rest in Peace ») et montrerons en quoi ces nouvelles ritualités peuvent, dans certains cas, poser problème.
Sustainability Struggles: Discursive Tensions in Latin American Cosmetic Industry
Authors: Angel Adriana , Álvarez-Nobell Alejandro
Published: June 2024

In attempting to understand how leading cosmetics brands in Latin America communicate their sustainability initiatives and corporate social responsibility, we ask the following questions: (a) how do social media stakeholders engage with the sustainability content communicated by leading cosmetic brands in Latin America?, (b) what discourses employ these brands to demonstrate their commitment to sustainability?, and (c) what tensions and contradictions are embedded within the sustainability and corporate social responsibility discourses of these brands? In order to address these questions, we focus on the analysis of four well-established brands within the Latin American cosmetic industry: Avon, Natura, O Boticário, and Yanbal. By embracing both qualitative and quantitative analyses, our findings help us to identify the tensions that arise when cosmetic companies strive to conciliate the pursuit of profit while advocating for sustainable development. Specifically, we argue that the discourse on sustainability of leading cosmetic brands in Latin America is especially appealing to audiences when it particularly points out environmental concerns and less so when it refers to social sustainability. Moreover, we show a nuanced interplay of tensions that encompass the juxtaposition of three dialectic relationships in this sustainability discourse: the tension between sustainability and capitalism, between corporate impact and consumer agency, and between empowerment and gender roles.

Published: June 2024

Hz. Peygamber’in ashâbı, bir takım şahsî özellikleri açısından hadis rivayetine farklı şekillerde katkı sunmuşlardır. Bu çalışmada da Yahudilikten ihtidâ etmiş bir sahâbî olması özelliğiyle dikkatleri çeken Abdullah b. Selâm ve hadis rivayeti ele alınmıştır. Müslüman olmadan önce Medine Yahudilerinin önemli ilim adamlarından biri olan Abdullah b. Selâm, Müslümanlar arasında da ilmî açıdan önemli bir yere sahip olmuştur. Sahâbîlerin ona sorular yönelterek onun eski dinine dair ilminden istifade ettikleri görülmektedir. Hatta Hz. Peygamber dahi bazı hususlarda onun Tevrat bilgisinden yararlanmıştır. Abdullah b. Selâm, hakkında birtakım ayetler nazil olan, aynı zamanda pek çok ayetin tefsirinde de kendisinden bahsedilen bir sahâbîdir Kur’an’ın Yahudi kökenli oldu-ğuna dair iddialarda adının zikredilmesi de Abdullah b. Selâm’ı önemli bir isim kılmaktadır. Hadis rivayeti açısından bakıldığında Abdullah b. Selâm’ın yetmiş beş rivayeti tespit edilmiştir. Bu yetmiş beş rivayet içerik olarak incelendiğinde ise aslında bunların toplamda elli rivayetin farklı versiyonları olduğu görülmektedir. Bu rivayetler çerçevesinde Abdullah b. Selâm’dan rivayette bulunan elli râvî tespit edilmiştir. Bunlar içerisinde sahâbî, muhadram ve tâbînden olanlar bulunmaktadır. İsrâiliyat üzerinden eleştiriye maruz kalan Abdullah b. Selâm’ın mevkuf rivayetleri içerikleri itibariyle incelendiğinde İsrâiliyat konularıyla alakalı olabilecek yirmi iki tane mevkuf rivayeti olduğu görülmüştür. Bu rivayetlerin içeriği genel itibariyle yaratılış, peygamberler tarihi, ahiret ahvâli, kıyamet alametleri, fiten ve melâhîm ile alakalıdır. Bu tür rivayetlerinin miktarı göz önünde bulundurulduğunda aslında onun İsrâiliyat konusunda çok abartılacak bir etkisinin bulunmadığını söylemek mümkündür.

كان هناك تقارير متزايدة عن الحيوانات الضالة والمهجورة والمُتنازل عنها في إمارة رأس الخيمة والإمارات الباقية خلال العام الماضي. وذلك أدى إلى زيادة الشكاوي من قبل المجتمع لمعالجة هذه القضية وما يترتب عليها من تكاليف ومطالب تقع على عاتق الحكومات المحلية، لأن هذه الحيوانات تشكل تهديدات بيئية وتهديدات تتعلق بالسلامة. وذلك يشكل تحدياً صعباً خصوصاً بما يتعلق بمسألة الحيوانات الضالة والمهجورة، لأنها تهدد النظام البيئي الطبيعي وتؤدي إلى صورة غير سارة في البيئة، مما يؤثر بشكل سلبي على الأعمال التجارية والسياحة المحلية. وتتطلب السيطرة على مجموعات الحيوانات الضالة والمهجورة تدخلاً بشرياً؛ ومن ناحية أخرى، فإن عددها يزداد بشكل كبير، مما يؤثر بشكل أكبر على البيئة ويزيد من التكاليف على المجتمع.

ويمكن استخدام العديد من الاستراتيجيات للسيطرة على الحيوانات الضالة والمهجورة، مثل برامج (إمساك –تحييد- إفلات) وعلى الرغم من ذلك، هناك العديد من العوامل التي تؤثر على فعالية برامج TNR، أبرزها معرفة المجتمع ووعيه. ويوصى بأن تُستكمل برامج TNR بمبادرات أخرى لزيادة الوعي وتثقيف الجمهور، والتي يمكن زيادة دعمها من خلال التعاون مع أصحاب المصلحة الآخرين في قطاع رعاية الحيوان.

وانطلاقاً من تحديد الاستراتيجيات اللازمة لدعم رعاية الحيوان ومعالجة الحيوانات الضالة والمهجورة في رأس الخيمة والإمارات العربية المتحدة بشكل عام فإن هذا التقرير يهدف إلى تحديد أصحاب المصلحة الرئيسيين، وما يتم القيام به حاليًا لدعم رعاية الحيوان - بما في ذلك TNR ، وفهم ووعي المجتمع حول هذه المواضيع. ويبدأ التقرير بمراجعة الأدبيات حول TNR، متبوعًا بشرح المنهجية المستخدمة. ونقدم النتائج في ثلاثة أجزاء: مشهد أصحاب المصلحة - ردود فعل المجتمع - وجهات نظر مسؤولي القطاع العام المعنيين، وذلك قبل أن نختتم بمناقشة التحديات والتوصية بالخطوات التالية المحتملة التي يجب النظر فيها.
User-Friendly Interface Attendance System Based on Python Libraries and Deep Learning
Authors: Ali Amna Kadhim , Mustafa Jalal Yaseen
Published: June 2024

The old methods used to manage attendance for students, employees, or even teaching staff using a paper attendance record are considered tiring methods that take time. In addition to errors and repetitions or forgetting to register attendance, even with the presence of manual fingerprinting, due to the diseases that the world has experienced in previous years, it has become undesirable for some because it is considered a means of transmitting infection. In this research, we propose a method to record attendance relying on face recognition technology with real-time video processing by using multi-layer perceptron algorithm with two of python libraries, where the camera device is accessed, a picture of the person is taken, and the image is processed and framed, comparing captured faces with images within the stored database, performing face recognition, then dealing with file operations, and managing time-related tasks. Once the desired person is found, attendance is recorded with the actual time entered into an Excel file, and the file is saved with the date of the day on which attendance was recorded. The designed system works efficiently in the real-time implementation of counting and detection, proven to combine high face-detection accuracy and performance.
Innovations in Electronic Control Units: Enhancing Performance and Reliability with AI
Authors: Aravind Ravi , Shah Chirag Vinalbhai
Published: June 2024

Electronic control units (ECUs) are the backbone of any automotive system. These computer systems have a range of functions, such as determining the air-to-fuel ratio, ignition timing, and idle speed for a just-started or driven vehicle. Having played these roles over the decades, today's automotive world is quite different, with a greater focus on getting from Point A to Point B with fuel efficiency, minimal vehicle operation, connectivity, user comfort, and minimal maintenance. It is the ECUs' responsibility to make this exploration comfortable, efficient, safe, and high-tech. Ensuring all this in an ECU-equipped vehicle requires the ECU to be quick, efficient, maintenance-free for some time, and more reliable. To complement these functions, today's ECUs must be more accurate, robust, capable of learning-driven optimization, AI-based capabilities, signals that help predict component life and determine vehicle operation parameters, and low-power and low-cost computational model architectures that handle these functions in real time. The main components that are subject to various types of environmental conditions are connected to the ECU.
In recent years, the automotive world has hit some high spots, such as autonomously operated vehicles, AI system-operating vehicles, and other intelligent and high-efficiency hardware operating vehicles. All these high-tech features have a great influence on the ECU's capabilities. In the present work, a range of existing and modern capabilities, features, technologies, ECU architectures, diagnostic methods, trends, and additional improvement suggestions based on requirements are briefly presented. The proposed suggestions are aimed at enhancing ECU capabilities and realizing the use of deep learning and AI in an ECU without losing the real-time, highly accurate data to be processed. High-technology sensors and methods to have influential data for ECU operations in real-time to process data are also presented. The regulatory requirements of specific countries for safer vehicle operation and to have a highly efficient and emission-free world for moving ahead are the spark for this research.

La finalidad de mi artículo es contribuir al desarrollo de un modelo general de la organización social del mundo andino, en el cual pocos se han interesado en los últimos diez años. Dos son los aspectos que voy a analizar en base a datos recogidos en el distrito de Tapay, en el valle de Colca, provincia de Cailloma, departamento de Arequipa. Primero, quiero analizar el patrón matrimonial que caracteriza por un lado la relación entre el distrito de Tapay y el rnundo externo, y por otro lado las relaciones entre los grupos sociales y culturales que forman la población de Tapay. En otras palabras, analizar cómo la exogamia y la endogamia se manifiestan en los diferentes niveles de la sociedad tapeña. Segundo, intentaré interpretar este patrón matrimonial dentro de un contexto más amplio, el de la organización social de Tapay. Por lo tanto, presentaré una serie de datos en torno al sistema de herencia en Tapay y la ayuda mutua entre los tapeños.

Program Petani Mandiri (PPM) adalah bantan hibah berupa barang kepada petani untuk memberikan kesejahteraan dan kemandirian petan. Penelitian ini mengkaji tentang implementasi kebijakan Program Petani Mandiri terhadap kebermanfaatan dalam penngkatan kesejahteraan petani di Desa Dander, Kecamatan Dander, Kabupaten Bojonegoro. Teknik pengumpulan data yang digunakan adalah observasi, wawancara, dan dokumentasi. Melalui wawancara dengan 2 ornag penyuluh pertanian dan 6 orang pengurus kelompok tani di Desa Dander ditemukan beberapa permasalahan dalam implementasi bantuan hibah uang Program Petani Mandiri, yaitu komunikasi antara implementor dengan kelompok sasaran dan kurangnya kompetensi pengurus kelompok tani sehingga menghambat implementasi bantuan hibah uang Program Petani Mandiri. Selain itu baik sebelum maupun setelah Program Petani Mandiri dilaksanakan, tidak ada perubahan perilaku petani di Desa Dander yang menunjukkan ciri petani mandiri. Pemberian bantuan berupa benih dan pupuk dapat dikatakan kurang bermanfaat apabila tidak ada perubahan perilaku yang mengarah pada kemandirian petani.

Adanya perbedaan kebudayaan dan nilai–nilai agama antara Etnis Uighur di Xinjiang dengan mayoritas penduduk Tiongkok menimbulkan diskriminasi yang terjadi pada Etnis Uighur di Xinjiang. Oleh karena itu, kelompok Etnis Uighur di Xinjiang melakukan perlawanan terhadap Pemerintah Tiongkok. Perlawanan yang dilakukan oleh Etnis Uighur di Xinjiang diantaranya terdapat perlawanan yang dilakukan oleh East Turkestan Islamic Movement (ETIM). Pada perlawanan yang dilakukan oleh ETIM menimbulkan pemberitaan pada media Pemerintah Tiongkok yaitu CCTV dan CGTN. Oleh karena itu, jurnal ini menjelaskan framing media Pemerintah Tiongkok terhadap East Turkestan Islamic Movement. Hasil dari riset ini adalah East Turkestan Islamic Movement sebagai bagian dari Etnis Uighur di Xinjiang dalam penelitian ini dikonstruksikan dan dibingkai oleh media Pemerintah Tiongkok sebagai teroris. Pemberitaan mengenai ETIM pada media CCTV dan CGTN yang merupakan media yang berada di bawah pengawasan Pemerintah Tiongkok membingkai peristiwa perlawanan yang dilakukan oleh Etnis Uighur di Xinjiang melalui ETIM sebagai tindakan teroris yang terjadi di Negara Tiongkok
Rojo carmín. La Federación Democrática Internacional de Mujeres y la Unión de Mujeres de la Argentina entre 1975 y 1991
Authors: Casola Natalia Laura
Published: June 2024

La actuación de las mujeres del Partido Comunista argentino (PCA) tanto en la Federación Democrática Internacional de Mujeres (FDIM) como en la Unión de Mujeres de la Argentina (UMA) no ha sido suficientemente explorada. En este trabajo nos proponemos realizar una reconstrucción de estas militancias en diferentes escalas de actuación entre 1975 y 1991. En primer lugar, buscamos recuperar el carácter transnacional del proyecto comunista poniendo el foco en las zonas de articulación y entrelazamiento de las militancias; en la materialización de un programa de aspiración mundial y su aplicación a una realidad concreta con sus especificidades. En segundo término, analizamos el periodo que se abre en 1975 con la sanción del Decenio de la Mujer por parte de la Organización de las Naciones Unidas (ONU) hasta la caída del Muro de Berlín y el inicio de la desintegración del mundo soviético. El objetivo es observar los cambios suscitados en las líneas como en las prácticas políticas desarrolladas en el cruce con los feminismos. Nuestra hipótesis es que el encuentro con los feminismos ayudó a renovar las agendas de lucha en el segundo lustro de los años ochenta, a la vez que fue importante como mecanismo de supervivencia de las militancias en el contexto de crisis y final de la experiencia soviética.
Mujeres, comunismo y activismo transnacional entre España y Francia (1960-1977)
Authors: Moreno Seco Mónica
Published: June 2024

Esta investigación propone analizar la evolución del antifranquismo y sus protagonistas desde un enfoque de género y transnacional. Aborda las relaciones establecidas en los años sesenta y setenta entre mujeres vinculadas al comunismo, a un lado y otro de la frontera hispano-francesa. A partir de fuentes archivísticas, hemerográficas y testimoniales, se centra en diferentes espacios de contacto e intercambio, e incluso de tensiones: el político, el solidario y el feminista. El estudio de las iniciativas y discursos desplegados por militantes y por organizaciones de mujeres afines a los partidos comunistas ha permitido detectar una amplia diversidad de experiencias y rescatar iniciativas hasta ahora poco valoradas. Estas redes transnacionales de mujeres antifranquistas contribuyeron a sostener la movilización antifranquista en el interior y dar sentido al internacionalismo en el exterior.

The primary objective of this investigation is to assess the influence of openings on the structural performance of ferrocement I-beams, incorporating diverse metallic and non-metallic mesh reinforcements. Sixteen beams underwent testing utilizing a four-point loading system until failure, categorized into four groups based on the type of mesh reinforcement. Each group comprised a control I-beam without openings and three additional beams featuring one, two, and three openings, respectively. To ensure consistent reinforcement weight, the four groups were reinforced with three layers of welded steel meshes, two layers of expanded metal meshes, two layers of Tensar meshes, and eight layers of Gavazzi meshes. Comparative analysis of the experimental outcomes was conducted with finite element models utilizing Abaqus. Therefore, there was good agreement between the experimental and numerical results. The findings showed that beams with no openings, one, and two openings reinforced with Gavazzi meshes had the highest ultimate load compared to other tested beams, while beams with three openings, those reinforced with expanded metal meshes had the greatest ultimate loads. Placing three openings in beams, with dimensions of 100×50 mm (two of these openings are approximately 10 cm apart from each edge while the third opening is located at mid-span), reduced the load-to-weight ratio by about 20.7%, 12.9%, 8.2%, and 23.8% for welded beams, expanded beams, Tensar beams, and Gavazzi beams, respectively, compared to the beams with no openings.
Ultimate drift ratio prediction of steel plate shear wall systems: a machine learning approach
Authors: Gürbüz Muhammed , Kazaz İlker
Published: June 2024

Predicting the ultimate drift ratio of steel plate shear wall (SPSW) systems is important for ensuring the structural integrity and performance of these systems under lateral loads. In this study, machine learning models are developed for predicting the ultimate drift ratio based on various design parameters using data from previous research on SPSW systems. These design parameters include the panel aspect ratio, column flexibility parameter, axial load ratio, web plate thickness and stiffness of horizontal and vertical boundary elements. A range of machine learning models is considered, including Random Forest, Lasso, Gradient Boosting, XGBoost, Adaboost, Artificial Neural Network and a stacked regressor. The models are trained and evaluated using data from 292 different SPSW models, and their performance is compared based on the R-squared value, root mean squared error (RMSE), and evaluation time. The results of this study demonstrate the effectiveness of machine learning techniques for predicting the ultimate drift ratio of SPSW systems. The results of this study show that machine learning techniques effectively predict the ultimate drift ratio of SPSW systems. Among the models considered, the ANN model achieved the highest R2 value, with a value of 0.94.
Modeling Missile Trajectory and Impact Dynamics with 6 Degree of Freedom Equations of Motion in Virtual Reality Simulation
Authors: Needhi Jeyadev , K Deepan Kumar , G Vishnu , B Vignesh
Published: June 2024

Existing methods for simulating missile dynamics and training often rely on three degrees of freedom (3DOF) motions, limiting their ability to represent the complex maneuvers and targeting strategies of modern missiles. This paper proposes integrating virtual reality (VR) technology with six degrees of freedom (6DOF) dynamics to enhance the accuracy and efficiency of missile simulation and training. By incorporating 6DOF dynamics, simulations can capture the full range of missile motion, providing a comprehensive understanding of their capabilities and limitations. Through VR, users can immerse themselves in realistic missile scenarios, interact with dynamic behaviors in real-time, and refine their targeting and interception skills. The integration of VR with 6DOF dynamics also facilitates real-time feedback and evaluation, enhancing training efficiency and proficiency in missile operations. This approach aims to revolutionize missile training by bridging the gap between traditional simulation methods and real-world dynamics.
