Entre penas e flechas: representações da temática indígena em livros diáticos de históriaa partir da lei nº 11.645/08
Authors:   , Siqueira Adriel Jonathas Fernandes
Published: February 2025

Ao completarmos uma década da Lei 11.645/2008 que imprime a obrigatoriedade do ensino da história e cultura africana, afro-brasileira e indígena, apresentamos um estudo sistematizado em três coleções didáticas para Ensino Fundamental e tencionamos um balanço acerca das representações indígenas nos livros de História. As coleções História Sociedade & Cidadania, História Nos Dias de Hoje e Integralis foram selecionadas mediante aprovação no edital 2017 do Programa Nacional do Livro Didático e utilização em escolas da cidade de Mossoró/RN. São elas a Escola Estadual Professor José de Freitas Nobre, Escola Estadual Moreira Dias e Escola Estadual Monsenhor Raimundo Gurgel. Como objetivo principal temos a análise e compreensão das representações histórico-culturais dos povos indígenas. E, entre os objetivos específicos, tangenciamos: a) o caminho das políticas indigenistas e indígenas no Brasil b) o reconhecimento da diversidade cultural indígena brasileira; e c) o estudo e compreensão dos conteúdos que explicam a história e cultura indígena no Brasil. A metodologia utilizada está ancorada em Bardin (2016) por meio da análise de conteúdos. Analisamos as representações indígenas por meio de textos e imagens presentes na história do Brasil. Para tanto, nos aportamos nos conceitos de Chartier (1988; 1990) e Hall (2015). Sucessivamente, na observação e problematização das imagens nos utilizamos de Burke (2004). No que tange os livros didáticos e suas dimensões, nos ancoramos de forma basilar nos estudos de Bittencourt (2002), e ainda, Munakata (2012). A respeito da diversidade cultural fizemos uso da referência indígena Luciano (2016), dos dados levantados pelo Instituto Brasileiro de Geografia e Estatística por meio do Censo 2010 e os escritos dos historiadores Silva e Costa (2018). As representações analisadas na pesquisa demonstraram quais imagens dos índios ainda moram em nossas cabeças. Há ainda uma ampla utilização de imagens no período colonial que produzem estereótipos, entre eles o mais recorrente é o do canibalismo. Imagens e textos que vão desaparecendo nos anos e livros subsequentes do ensino fundamental. Contudo, apesar de algumas continuidades, há esforços por parte de editoras que produzem transformações significativas no ensino da história e cultura indígena. A Lei aliada às práticas docentes trouxeram mudanças significativas, porém apesar do caminho construído há muito que se fazer
Therapeutic Potential of Terpenes in Lung Cancer: Modulation of 4-Oxo-Retinoic Acid, TNF-α, NF-κB, and HDAC2 Pathways
Authors: Pant Janmejay , Mittal Payal , Singh Lovedeep
Published: February 2025

Non-small cell lung cancer (NSCLC) includes various epithelial malignancies, such as squamous cell carcinoma, large cell carcinoma, and adenocarcinoma. Despite ad-vancements in surgical resection, chemoradiotherapy, and multimodal therapies, NSCLC prognosis remains challenging due to its complex molecular landscape, drug resistance, and high treatment costs. Recent research highlights the potential of natural compounds, particularly terpenes and terpenoids, derived from essential oils (EOs), to enhance NSCLC treatment. These compounds exhibit anticancer properties and modulate key pathways like the 4-oxo-retinoic acid pathway, TNF-α signaling, NF-κB activation, and histone deacety-lases (HDACs). Retinoids, a subclass of terpenes, show both chemopreventive and thera-peutic benefits, especially when combined with other agents, though challenges in dosing and delivery methods limit their clinical application. Terpenes may also synergize with emerging therapies, such as antiangiogenic treatments and immunotherapy, to improve outcomes. Biomarkers, including genomic, epigenomic, and proteomic markers, play a critical role in predicting responses to terpene-based treatments, supporting personalized medicine. The integration of terpenes into existing regimens, in combination with conven-tional therapies, holds promise in overcoming clinical challenges, improving patient out-comes, and advancing natural compound use in modern oncology. Future research should focus on optimizing terpene therapies and addressing clinical hurdles.

The learning process is the mental activity of individuals in communicating with their environment which is invisible but can be proven through behavioral transformation in a positive direction. In reality, there are several difficulties faced by students such as students who have undergone a deep learning process but still have difficulty achieving learning achievements at school. Learning difficulties experienced by students must be diagnosed by the teacher which aims to determine the situation of student learning difficulties. However, there are obstacles in the unavailability of complete instruments to measure student learning difficulties and teachers have a lack of understanding of the use of measurement instruments. The questionnaire instrument will help teachers in diagnosing students' learning difficulties. Before its development, a needs analysis stage is needed to adjust the characteristics of the instrument design according to the data in the field. The needs analysis using a questionnaire consists of 3 aspects (17 questions) with 7 chemistry teacher participants in Yogyakarta. The needs analysis questionnaire has been validated by chemistry learning experts. The results of the data were analyzed using descriptive qualitative by presenting data or answers calculating frequencies and percentages. It was concluded that the development of a student perception scale instrument on chemistry learning difficulties has an urgency that is quite important because of the limitations or unavailability of these measurement instruments.

Statistical Analysis for Storage Utilization Forecasting
Authors: Gonga Bala kishore
Published: February 2025

Sonatype Nexus is a robust repository management tool commonly utilized in DevOps and CI/CD workflows. It
facilitates the efficient management, storage, and retrieval of binary artifacts. Nexus is integral to software development,
offering centralized storage and organization for build artifacts, dependencies, and containers, thereby enhancing team
collaboration and ensuring control over the software supply chain. On a daily operational basis, various artifacts are uploaded
across multiple repositories in each Nexus instance. It is the administrator’s duty to free up space whenever it exceeds a certain
threshold. Failing to do so may result in server shutdowns, negatively impacting business operations. While the administrator
can utilize automated tasks from Nexus, these have certain constraints, especially when it comes to deleting specific artifacts.
This poses a challenge when valuable artifacts occupy a significant portion of space, causing a reduction in available storage
without clear indication of when the server will fail.
This paper addresses the issue by applying a machine learning model, specifically Linear Regression, to analyze space usage
patterns. The regression model will derive an equation based on existing data, enabling predictions of future space consumption
and offering a proactive solution to manage server capacity.

Explainability in AI: Interpretable Models for Data Science
Authors: Ali Ali Mohammed Omar
Published: February 2025

As artificial intelligence (AI) continues to drive advancements across various domains, the need for explainability in AI
models has become increasingly critical. Many state-of-the-art machine learning models, particularly deep learning
architectures, operate as "black boxes," making their decision-making processes difficult to interpret. Explainable AI (XAI)
aims to enhance model transparency, ensuring that AI-driven decisions are understandable, trustworthy, and aligned with
ethical and regulatory standards. This paper explores different approaches to AI interpretability, including intrinsically
interpretable models such as decision trees and logistic regression, as well as post-hoc methods like SHAP (Shapley Additive
Explanations) and LIME (Local Interpretable Model-Agnostic Explanations). Additionally, we discuss the challenges of
explainability, including the trade-off between accuracy and interpretability, scalability issues, and domain-specific
requirements. The paper also highlights real-world applications of XAI in healthcare, finance, and autonomous systems. Finally,
we examine future research directions, emphasizing hybrid models, causal explainability, and human-AI collaboration. By
fostering more interpretable AI systems, we can enhance trust, fairness, and accountability in data science applications.

The quality of potato seed material is one of the main factors determining its yield. Under the
long-term reproduction potato accumulates diseases, mostly viral. Viral diseases cause the decrease
in yield 2-3 times, worsen the quality of tubers. It is possible to solve this problem by creating virusresistant varieties, as well as by switching seed production to a virus-free base (healthy basis). Creation of the virus – free collection under the in vitro conditions is the basis for the development of
potato seed production in any region of the Russian Federation. In this regard, the purpose of this
work was to study the question of improvement of varieties and selection of optimal conditions for in
vitro reproduction and collection of healthy virus-free potato varieties for the use in seed growing
programs of Primorsky Krai and the Far East Region. Federal Research Center for Agrobiotechnology in the Far East Named after A. K. Chaika has created and maintained under the in vitro conditions the collection of 18 virus-free improved potato varieties. The article presents the results of in
vitro micropropagation of potato varieties using nutrient media with different composition. The possibility of recovery from viruses by means of the joint use of tissue culture (apexes 2-4 mm) with
chemotherapy (ribavirin) has been demonstrated with the new variety of potato Augustine. The testtube plants obtained through tissue culture have been tested by ELISA as to latent infection with
viruses: HVK (x potato virus), SBK (s potato virus), MVK (M potato virus), YBK (Y potato virus),
VLK (potato leaf twisting virus), as well as to the presence of bacterial infection in the testing laboratory for the diagnosis of potato diseases of our institution. Thus, we have selected the composition
of the nutrient medium for the micropropagation of potatoes, that provides the maximum values of
the reproduction factor of varieties. The method of tissue culture in combination with chemotherapy
improved and introduced into the in vitro culture the new variety of potato Augustine.

Soybean is one of the crops that is difficult to transform due to a significant reduction in the
ability to regenerate after inoculation with agrobacteria. The effectiveness of the transformation depends not only on the plant species, but also on a number of other factors and can vary greatly among
different varieties. The research paper presents the results of in vitro regeneration potential for agrobacterial transformation of soybean varieties. Test material-varieties of soya: Hodson, Primorskaya
28 and Primorskaya 4. The explants of varieties ready for transformation were formed as follows: 38
explants of the variety Primorskaya 28; 42 explants of the variety Primorskaya 4; 54 explants of the
variety Hodson and 21 explants of the variety Primorskaya 81. During the kanamycin-resistance
breeding, 65 kanamycin-resistant plants were selected in one month. Most kanamycin-resistant plants
were derived from the genotypes of Hodson and Primorskaya 4 varieties. The research resulted in in
vitro assessment of transgenic soybean plants, obtained by the method of agrobacterial transformation and containing AMP-1 gene in their genome. The assessment was carried out under the control of constitutive 335 CAMV promoter and NOS terminator, which makes it possible to extend the
limits of plant resistance to phytopathogens. Immunological analysis showed that the degree of leaf
damage to transformant plants from Septoria (Septoria glycines Hemmi) is 42% lower than that of
the standard variety and 74% lower than that of the original form. According to the results of biochemical analysis, the transgenic line exceeded the content of protein and oleic acid in the seeds. At
the same time the content of linolenic acid reduced, which improves the quality of soybean oil.

The research paper considers the results of monitoring the phytosanitary condition of rice crops
on the Primorskiy Territory. Route surveys of the state of rice crops in the phases of germination,
tillering, and booting were carried out. The percentage of damage to the plant, characterizing the
spread of the disease and the degree of manifestation of its forms is determined. Preliminary assessment of 7 rice samples selected at the farms of the region and 15 variety specimens (samples) of
breeding material of the station was carried out in relation to local populations of piricularia oryzae
resistance in the laboratory and under conditions of the greenhouse at the Far East Research Institute for Plant Protection. The authors studied the influence of biological races of the piricularia oryzae (causative agent of rice blast) on rice varieties and variety specimens isolated in the control
nursery, collection samples of ecological–geographical, ecological origin, as well as samples resistant
to the disease as the result of the control of the Far East Research Institute for Plant Protection. The
greatest spread of the pathogen Magnoporthe grisea (Herbert) Barr 52,5% was found at the farms:
Zelenodolskiy, Petrovichanskiy and Vladimiro – Petrovskoye. Two stable varieties H-1, H-12 in the
Spasskiy District of Primorsky Krai and rice varieties M-19 in Khankai District of Primorskiy Territory were singled out for further testing. They showed resistance to contamination caused by various
races of piricularia oryzae; 2 varieties were characterized as highly resistant (16.8%). The research

The article presents the findings of investigations and testing of track-type harvesting and
transport machines working on wetted soil. The use of rubber-reinforced caterpillar in undercarriage
systems of harvesting and transport machines has the following effect: a) increase passability of the
machines on soils with low bearing capacity; b) eliminates damage to roads and soils; c) reduces the
maximum pressure and compaction of soil 2.5 times as compared to the metal caterpillar, U=73.1
kN / m, which is below the safe limit for soils [U]=75 kN/ m. Re-equipped harvester or tractor reduces
the anthropogenic impact on the soil, reduces the degree of compaction, increase productivity, improve traction and coupling properties, as well as reduces the amount of slipping.

Today scientific and technical literature presents more and more research papers on the environmental safety of maintenance of tractors, combines and other machines in the field. This also
includes patents for inventions in this area. Under modern social and economic conditions, the interest aroused to this direction of researches is caused, first of all, by high level of technical culture
of the service personnel, and also by need of improvement of environmental safety of machine operation. According to the rules of GOST (State Standard) 20793-2009, the maintenance is carried out
not only at the service stations, but also in the places of work of the machines – in the field, in contact
with wildlife. If this is the case, then the question of ensuring the environmental safety of machines
maintenance arises certainly, and this question is not of lesser importance than in a case when the
machines are used for their intended purpose. Since the maintenance of machines in the field is
performed with the help of mobile maintenance facilities (maintenance units), the environmental
safety of the process of maintenance in the field depends largely on the environmental safety of the
use of these facilities. In the practice of technical maintenance of machines today they use models of
maintenance units that are different in technical characteristics. However, it has not yet been established how these maintenance units meet modern requirements of environmental safety. In addition,
the assessment of environmental safety of maintenance units is quite desirable when putting them
into production and during state acceptance tests (SAT), as well as when choosing the best model of
maintenance unit. Of course, the solving of these issues requires science-based methodology for definition of the environmental safety of the mobile maintenance facilities, the substantiation of which
is the aim of this research paper. Owing to its implementation we proposed theoretical bases for
determining the environmental safety of the maintenance units in the course of the machine maintenance in the field. At that we took into consideration all kinds of services effected in the field using
mobile maintenance facilities; the indicator accepted at the input as the main ecological parameter:
«getting fuel and lubricants into the soil», at the output - coefficient of environmental safety, base of
comparison - similar data obtained while servicing machines at the maintenance stations.

Students' mathematical reasoning abilities are relatively low. To enhance these skills, specific teaching and learning strategies can be implemented, which require students to engage in problem-solving activities and apply their knowledge to real-life situations. This research adopts a quantitative approach to examine the Q-STEAM module's effects on students' mathematical thinking skills. The participants of this study consisted of 65 senior high school students from Aceh, who were selected using convenience sampling and divided into experimental and control groups. The study employed a quasi-experimental method with a pretest-posttest non-equivalent group design. The research employed an essay question as a tool for mathematical thinking instruments. The data collected from the mathematical thinking test was analyzed using an independent sample t-test. The findings revealed statistically significant differences in the mean scores of mathematical thinking skills between the two groups. Furthermore, the descriptive statistics showed that the students in the experiment group had better mathematical thinking skills than those in the control class.

The school climate plays a pivotal role in students’ outcomes. Previous literature has highlighted several methodological approaches employed in the school climate domain, including longitudinal studies. However, little is known about the validity and reliability of school climate instruments for longitudinal studies using Rasch analysis. Rasch model is a powerful approach to validate assessment on both item and test levels. Rasch model is coined from the probability of each response and includes item difficulty parameters to characterize the measured items. Moreover, the score represents the item and the person involved with the assessment. Thus, the current study aimed to validate school climate instruments for longitudinal studies with a six-month gap within the context of secondary school students by utilising Rasch analysis. This study evaluated aspects of reliability and validity, such as unidimensionality, rating scale analysis, item fit statistics, item targeting, and differential item functioning. A total of 1,495 secondary school students from public schools in Selangor, Malaysia, completed a 28-item Malay version of the school climate survey at Time-1 and Time-2, with a six-month gap. The results of the Rasch analysis indicated that the instrument had excellent reliability and separation indices, excellent unidimensionality and construct validity, a functional rating scale, good item-person targeting, and good item fit statistics. The current findings provided valid and reliable insights pertinent for policymakers to strategise interventions and initiatives to enhance the quality of school climate and overall education, particularly in the Asian context.

This ongoing study delves into the effects of using the native language (L1), specifically Spanish, on the process of learning English as a foreign language (EFL) in different academic environments. These include adult learners at UNAD and secondary school students in Colombia. This research examines students’ perspectives on the incorporation of L1 in English lessons and its impact on their learning outcomes. Through surveys, on-site observations, and performance evaluations, the research explores how the strategic integration of L1 through codeswitching influences English acquisition. The initial findings, reached through all the previously mentioned data and analysis tools, indicate that thoughtful incorporation of L1 in EFL classes lowers the emotional barriers and fosters the growth of linguistic awareness, potentially boosting students' proficiency levels.
