Double conscience et afro-descendance
Authors: Mansouri Malika , Pouye Ada
Published: February 2025

Cet article propose une réflexion sur la condition noire en interrogeant l’application du concept de « double conscience » duboisien dans le contexte français contemporain. Il participe d’une étude qualitative et inductive réalisée sur le modèle de l’enquête de terrain et qui s’appuie sur des entretiens non directifs réalisés auprès de personnes afro-descendantes françaises. S’inscrivant dans une démarche interdisciplinaire, l’analyse psychanalytique que nous proposons se veut à la croisée de regards sociohistoriques et philosophiques sur la condition noire en contexte français. Cette analyse met en lumière la prépondérance de la ligne de partage des couleurs dans la structure de nos sociétés modernes. Partant de là, elle rend compte de l’implication de cette ligne dans les processus de subjectivations des personnes afro-descendantes, de l’identification à la blancheur à la révolte sociale en passant par la guerre contre soi-même.

Authors: Akhal Najat
Published: February 2025

. The environment in the region of Tadla is undergoing a very worrying degradation, which manifests itself in terms of environmental injustice in general and that of climate change, which in turns affects other environmental resources such as water at first degree, through scarcity and inequality in terms of quantity and temporal and spatial distribution. This scourge is becoming widespread in the most areas, especially those in arid and semi-arid regions. This influence is manifested at the level of the injustice of groundwater resources, those suffering from a very important deficit in the whole national territory, especially the case of the irrigated perimeter of Tadla. The groundwater in this area is experiencing a very sharp decline in the piezometric levels of the groundwater and deep groundwater which is causing a dangerous challenge that prevents the satisfaction of drinking water and agricultural needs.

Integrating KMS with advanced technologies like knowledge graphs and semantic technologies can greatly enhance their functionality in business contexts. This research aims to systematically reviews and evaluates studies on the integration of knowledge graphs and semantic technologies. The study follows PRISMA guidelines for methodological rigor. The review includes articles published between 2005 and 2024 from databases like ScienceDirect and IEEE Xplore, focusing on keywords such as “knowledge graph” and “knowledge management systems.” From an initial 18,900 articles, 73 were selected for detailed analysis. The findings indicate that using tools like RDF, SPARQL, OWL, and SKOS enhances KMS capabilities, enabling features like semantic search and intelligent recommendations. However, challenges such as scalability, semantic disambiguation, and data privacy need to be addressed to fully realize KMS's potential in supporting organizational knowledge management.
A Novel Model of Ecological Physical Education Teaching in the Urban Particulate Matter 2.5 Environment
Authors: Zhou Mei , Liu Yang
Published: February 2025

Eco-sports teaching serves students' physical and mental health and pays attention to the interaction between natural environment and people, which is one of the teaching methods in line with the current teaching reform trend. From the perspective of students' sustainable and healthy development, this paper studies the influence of urban PM2.5 concentration on students' physiology and psychology.It is found that when PM2.5>100 ug/m3, the frequency of students' medical treatment and the rate of abnormal pulmonary ventilation function will increase. Based on 857 valid questionnaires and Pearson correlation analysis,the research shows that when the concentration of PM2.5 increases,the air visibility changes and the air smells,it is highly correlated with the psychological stress of students. Creating physical education courses suitable for high PM2.5 concentrations both meets students' needs and promotes sustainable development of ecological physical education classes.

Soil compaction in Northern Italian vineyards: challenges and mitigation strategies
Authors: Pessina Domenico , Tadini Valeria , Galli Lavinia Eleonora
Published: February 2025

Soil compaction presents significant challenges for perennial crops, which occupy the same land for many years. The practice of arranging plants in rows and the frequent use of heavy machinery is leading to soil compaction and rut formation. A study conducted in espaliers vineyards in Northern Italy (Oltrepò, Lombardy region) examined the effects of grass-covered versus tilled inter-rows and the influence of mechanical versus manual harvesting. The study was based on a series of penetrometer resistance measurements conducted throughout the entire growing season. Early-season measurements revealed values exceeding 4 MPa, surpassing the 1-3 MPa threshold identified in the literature as a limit for root growth, grape quality, and susceptibility to pathogens. The negative impact of soil compaction was not limited to the ruts formed by agricultural machinery but also affected adjacent areas. The well-documented regeneration of agricultural soil structure during the cold season was in these cases inadequate to alleviate the significant compaction observed. Furthermore, mechanical harvesting, particularly in wet conditions, significantly exacerbated soil compaction, with measurements indicating nearly 5 MPa in ruts. These findings underscore the imperative for implementing strategies aimed at mitigating the adverse impacts of soil compaction on vine health and the sustainability of vineyards.
Choroidal ocular metastasis in a treated case of postmastectomy breast cancer patient: A rare event
Authors: Kulshrestha Asmita , Bhoj Priyanka , Pandagle Amitabh , Jawale Deeksha
Published: February 2025

Breast cancer is a major global health concern, accounting for a significant percentage of cancer cases and deaths in women. Despite advances in screening and management of breast cancer, a significant number of people with early-stage treatment still have recurrence or metastasis, primarily affecting the bone, lung, liver, and brain. Ocular metastasis, particularly to the choroid, is uncommon but may occur, indicating broad dissemination of the initial tumor. This case report covers a 45-year-old perimenopausal female with a history of left breast infiltrating ductal carcinoma who had undergone modified radical mastectomy with adjuvant chemotherapy and radiation therapy. She presented with impaired vision in her right eye, which was discovered to be caused by choroidal metastasis from breast cancer. She also had widespread distant metastasis affecting the bones and liver. Despite palliative chemotherapy, radiation therapy, and hormonal therapy, the patient’s condition advanced, resulting in survival failure. This case emphasizes the significance of regular follow-up for breast cancer patients to watch for signs of metastatic spread, as late discovery can lead to advanced disease and worse outcomes. Visual complaints in breast cancer patients should arouse suspicion of ocular metastasis, emphasizing the importance of communication between oncologists and ophthalmologists and creating patient awareness. Timely detection and intervention are critical in controlling metastasis, especially when it affects uncommon locations like the eye.

Published: February 2025

The treatment of primary neuroendocrine neoplasms (NENs) of the female genital tract is difficult since they are rare, aggressive, have a high recurrence rate, and have poor prognosis. As no established guidelines exist, diagnosing and treating them can be extremely difficult for clinicians. This case study explains the role of histopathology and immunohistochemistry in diagnosing a rare neuroendocrine carcinoma of the left adnexa. Investigating novel therapeutic approaches that can enhance the clinical result for such uncommon cases is imperative.
Suicidality in Patients with Substance Use Disorders: A Narrative Review
Authors: Kuppusamy Vignesh , Sarkar Siddharth , Balhara Yatan Pal Singh
Published: February 2025

Substance use disorders (SUDs) have been associated with suicidality. Several types of SUDs have been associated with self-harm attempts, suicidal attempts, and completed suicides. There are various risk factors that have been associated with suicidality in individuals with SUDs. The literature on this aspect is wide, and hence, there is a scope for a narrative review that covers the various aspects of the relationship between suicidality and SUD, including consideration of preventive aspects. This narrative review presents the synthesis of the literature on the association of substance use and SUD with suicidality, the risk factors that predispose an individual with SUD to suicidal behavior, and what kind of measures can be taken to address suicidality among persons with SUD. Strong associations were reported between SUD and suicidality. A higher prevalence of self-harm in females with SUD was reported by certain studies. Comorbid mood disorders, psychotic disorders, personality traits, lack of formal education, unemployment, poor family support, high smoking rate, early age of drinking, and polydrug use were several risk factors for suicidality in SUD. Weaker evidence of an effective intervention to prevent suicide or reduce self-harm among people with SUDs was reported by several randomized control trials. Some studies recommended environmental interventions such as a reduction in the number of bars. Nevertheless, policy-level changes like increasing alcohol taxes have resulted in decreasing alcohol-related morbidity and mortality, violence, traffic crash fatalities, drunk driving, rates of sexually transmitted diseases and risky sexual behavior, other drug use, and crime but failed to establish a statistically significant reduction in suicidal rates associated with SUD.

Published: February 2025

Global warming and climate change are issuesthat interests notonlythe academic or political circlesbut have entered the doorstep of every country, state, metropolis, town and village with obvious warning signs. Though climate change is the largest health threat the world is facing today, it also brings in a great opportunity to redefine the social and environmental determinants of health.Women and children are affected disproportionately by climate change more due to social, economic and cultural factors particularly in low-income countries and in rural areas. This can involve issues like food and water scarcity, displacement, migration, loss of housing, education, early marriage, gender violence, job losses which affect women more. Major burden here is on nutrition with increasing malnurition in women and children. We have re-iterated that it is time for policy actionand financing at political level and action at individual level to consider the specific needs maternal and child health care in climate change hazards. It is our collective responsibility to listen and put mother and child at the centre of urgent climate agenda. Urgent actions are needed in reduction of greenhouse gases, with specific inclusion of needs of pregnant women, babies and children in climate related policies.

Published: February 2025

The rapid advancement of information technology has encouraged companies and institutions to enhance data management more effectively and efficiently to support productivity. The online report card system at MTs Al Mumtaz is designed to manage student grades digitally. Currently, grade processing at MTs Al Mumtaz is still done manually using Microsoft Excel, without a specialized application. With a web-based system, it is expected that grade management will improve, allowing students and parents easy access to grades, while also simplifying data entry for teachers, making the process more efficient. This research uses the Waterfall method, with UML, PHP, MySQL, and the CodeIgniter (CI) framework as tools. The results show that the developed online report card system can enhance efficiency in grade management, reduce the risk of data entry errors, and speed up delivering grade information to students and parents. Additionally, the system facilitates teachers in managing grades, both in terms of data entry and final grade processing. The author recommends further development of this system, with additional features such as automatic notifications and mobile application integration, making user access easier and the report card system more optimized.

Published: February 2025

Pyrolysis of agricultural waste to biochar presents a valorization pathway for wastes in an environmentally friendly way. The study focuses on the optimization of biochar production from cassava peels using response surface methodology. Three most important process parameters were considered for optimization: pyrolysis temperature (350-750 °C), heating rate (5-25 °C/min), and reaction time (20-130 min). For that, a Box-Behnken experimental design has been employed to develop a predictive model for biochar yield and other responses of interest: pH, bulk density, and surface area. The developed empirical models for predicting biochar characteristics with high accuracy were validated through diagnostic plots and experimental trials. It was seen that temperature, heating rate, and reaction time substantially affected the yield of the biochar. The maximization resulted in an overall increase in the physicochemical properties of biochars. This study illustrates scalable applications of biochar and establishes the predictive model for real validation experiments for the application of process flow modeling of biomass pyrolysis. This work emphasizes the optimization of parameters in the production of biochar and gives a real platform for the use of agricultural residues in sustainable waste management and environmental remediation. The predictive model developed can be used as an important tool in designing efficient biomass conversion processes.

Fractured Identities: Caste, Gender and Violence in Poonachi: The Story of a Black Goat and One Part Woman
Authors: Raj G Akil , Lazarus Anderleen Diana
Published: February 2025

This study analyzes Perumal Murugan's Poonachi: The Story of a Black Goat and One Part Woman to explore the multifaceted theme of fractured identity within the context of caste, gender, and violence in India. Murugan's novels offer a powerful lens through which to examine the complex interplay between personal and collective identities as characters navigate the oppressive forces of tradition and societal expectations. Poonachi, through the symbolic representation of a black goat, and One Part Woman, through the experiences of a marginalized woman, expose the devastating consequences of caste-based discrimination and gender inequality. Murugan's innovative narrative style and evocative symbolism provide a poignant critique of how cultural and social hierarchies shape individual experiences and identities. The precarious existence of Poonachi, subjected to societal whims and the vulnerabilities inherent in her animal status, mirrors the struggles faced by marginalized communities. Similarly, the female protagonist in One Part Woman grapples with societal pressures and expectations, highlighting the restrictions imposed on women within patriarchal structures. By examining the protagonist's struggle for agency and the reclamation of her narrative in One Part Woman, alongside the symbolic journey of Poonachi, this paper illuminates the enduring impact of historical and contemporary forms of oppression on marginalized communities in India. The research delves into the ways in which both novels challenge traditional power structures and offer a nuanced understanding of the psychological and social ramifications of marginalization.

Published: February 2025

Purpose: This study aims to investigate the moderating effect of technology readiness on the relationship between inventory management techniques and supply chain efficiency.
Methodology: The research design for this study adopts a quantitative approach, supplemented by elements of a survey methodology. A cross-sectional design is employed, as data was gathered at a single point in time, making it suitable for identifying patterns, relationships, and variations within the research context. The quantitative design is grounded in the need to test hypotheses and draw objective conclusions. This study employs convenience sampling to obtain a sample size of 280. This study utilizes structured survey questionnaires as the primary data collection instrument.
Findings: The findings of the study concluded that there is a strong and statistically significant relationship between inventory management techniques and supply chain efficiency. Positive significant relationship exists between technology readiness and supply chain efficiency. Technology readiness positively moderates the relationship between inventory management techniques and supply chain efficiency.
Unique Contribution to Theory, Practice and Policy: The findings challenge traditional supply chain efficiency models that primarily focus on inventory management techniques as the central factor influencing performance. By introducing technology readiness as a moderating variable, this study expands existing models to incorporate the role of technological infrastructure and employee preparedness in the effectiveness of inventory management. The strong moderating effect of technology readiness suggests that organizations cannot solely rely on optimizing inventory management techniques without considering their technological capabilities. Managers should recognize the interdependence between inventory management techniques and technology readiness and prioritize both areas simultaneously.

Authors: P Sravya Sri , M Sowjanya , Venugopalaiah Penabaka , Y Prapurna Chandra , Yerikala Ramesh
Published: February 2025

Urinary tract infection is one of the commonest infections to affect humans. Uncomplicated infections occur most commonly in  healthy women .when uropathogenic bacteria, usually Escherichia coli, ascend from the perineum into the bladder and overcome host innate immunity. Complicated infections occur in patients with an anatomical or functional abnormality of the urinary tract. The diagnosis is made on the basis of symptoms and diagnostic precision is improved by urinalysis. Urine culture is important with severe, recurrent or complicated infection and when the diagnosis is unclear, for example, in children and the elderly. Most women with symptoms that resolve quickly do not require further investigation but in children, men and patients with recurrent or severe infection, imaging of the renal tract, functional testing and cystoscopy should be considered to exclude an underlying abnormality. Pivmecillinam is the pro-drug of mecillinam, a ?-lactam antibiotic with a novel site of action and with specific and high activity against Gram-negative organisms such as Escherichia coli and other Enterobacteriaceae. Since its introduction, it has been widely used for the treatment of acute lower urinary tract infections (UTI), primarily in the Nordic countries. In contrast to the increasing resistance of urinary pathogens to other ?-lactams particularly ampicillin/amoxicillin and to other UTI antibiotics such as trimethoprim and trimethoprim/sulphamethoxazole (TMP/SMX), the level of resistance has remained on a low level. Less than 2% of E. coli community isolates are resistant to mecillinam. This paper reviews the clinical data on Pivmecillinam with a special focus on the safety aspects. Exblifep is a novel ?-lactam/?-lactamase inhibitor combination and a potential empirical therapy for resistant gram-negative infections. Exblifep noninferior to piperacillin/tazobactam for the primary outcome of treatment efficacy in patients with complicated urinary tract infections (UTIs) or acute pyelonephritis.

Discussion on the Definition, Boundary and Rationality of Academic Freedom - A Philosophical Dimension Based Examination
Authors:   School of Development and Sustainability, Asian Institute of Technology, GUO Jianan
Published: February 2025

Academic freedom is the guarantee of knowledge production and scientific research. Academic freedom is essential for the progress and development of modern free society. By analyzing previous studies, this paper makes a new interpretation and explanation of the definition, boundaries and rationality of academic freedom from a philosophical perspective. In terms of its definition, academic freedom means that academic subjects are not arbitrarily dominated by other individuals or groups in the knowledge field of life, and they properly control their own wishes and actions in this field. In terms of its boundaries, academic freedom should protect the corresponding institutions as long as they or their activities are characterized by practical activities that generally promote the advancement of knowledge and understanding. In terms of its rationality, academic freedom is an appropriate consideration of the knowledge field of social life. Furthermore, from the perspective of individualism, the rationality of academic freedom is reflected, and it is proposed that the realization of academic freedom lies in the fact that researchers should use the methodology of reliability to conduct investigations and research, and university academic subjects should accept strict scrutiny from the society and the authoritative institutions of the academic community in free academic research, and protect teaching institutions that aim to pursue the truth, thus providing theoretical guidance and practical significance for inspiring innovation for the future development of academic freedom.

Published: February 2025

We aim to evaluate the health impacts of the Fundão tailings dam disaster by analyzing secondary data collected from various databases of the Brazilian Ministry of Health and conducting a study to assess the burden of disease using years of life lost due to disability and the disability-adjusted life year (DALY) indicator as a summary measure.
An ecologic study design was used to compare municipalities affected by the disaster with a group of controls. Based on the incidence of diseases registered in public databases, an assessment of the impact on mental and physical health associated with the disaster was carried out using a burden of diseases approach. DALYs were calculated for all the diseases identified based on the evaluation of the epidemiological parameters: (i) attributable risk (AR) ratio, (ii) ratio of cumulative incidences (CIs) before and after the disaster, and (iii) a plausibility coefficient, idealized in order to express the relevance of the health conditions identified to a set of health conditions plausibly associated with the disaster.
Key findings include the estimation of an average loss of 2.39 years of life due to disability for the affected municipalities, considering 75 groups of diseases that had higher CIs and ARs after the disaster, compared with a set of control municipalities, indicating a worsening of health of these populations. We also identified respiratory diseases, various types of cancer, mental disorders, and violence as responsible for a very significant portion of the damage identified.
We included a series of public health recommendations that can be implemented to facilitate the resilience of those living in affected municipalities.
The gut microbiome and osteoarthritis
Authors: Krupka Wiktoria Maria , Motyl Gabriela , Dmowska-Chalaba Joanna
Published: February 2025

Osteoarthritis (OA) is one of the most common degenerative diseases, and the number of patients has been constantly increasing. Non-steroidal anti-inflammatory drugs, glucocorticosteroids, opioids, etc., and surgical procedures, e.g. arthroplasty, are among the most common methods of treatment. There are reasons to believe that the gut microbiome (GMB) may influence inflammatory processes occurring in the pathomechanism of OA. The inflammatory processes occurring in the intestines may lead to disruption of tight junctions and increased concentrations of pro-inflammatory cytokines, resulting in increased permeability of intestines, causing low-grade inflammation, including in the joints. Methods of altering the GMB composition to reduce the inflammatory and joint dege­nerative processes are known only to some extent, and long-term research is required.
Osteoarthritis, a particularly well-known and very widespread disease due to the aging population, is characterized by moderate and local inflammation. It occurs due to the effects of biomechanical cartilage wear with damage of joint structures, primarily through degenerative processes. OA represents a therapeutic challenge, and any element that can influence its inhibition is highly sought after. Therefore, these methods seem to offer a promising additional approach to treatment.

Published: February 2025

Abstract. The on-going global warming is causing rapid changes in the carbon cycle of the Arctic. Yet the response of the Arctic to these environmental changes are not fully understood. In this study, we investigate bulk organic parameters (TOC, TN, δ13Corg, δ15N, C/N) and terrestrial n-alkanes (TERR-alkanes) from 19 surface sediments and 5 210Pb-dated sediment cores covering up to the last three centuries from the Chukchi Sea. Downcore profiles indicate increasing OC since the beginning of the Industrial Era in all cores. They also show higher TOC and TN values in southern Chukchi Sea cores coincident with decreasing δ13Corg indicating an increasing contribution of terrestrial OC that is confirmed by TERR-alkanes. Comparison with regional paleo-records and instrumental data emphasize the key role of air temperature and sea ice cover on the OC cycle and vegetation of the surrounding landmasses.
Philanthrokapitalistisches Engagement in der Stadt. Memetische, hörbare und kartographische Perspektiven auf Heilbronn
Authors: Schmidt Katharina , Restrepo Lopez Iris Veronica
Published: February 2025

Abstract. While philanthropic involvement in cities is not a novelty in itself, the integration of entrepreneurial logics into foundation activities and their influence on urban developments is increasingly being discussed under the term philanthrocapitalism. In the city of Heilbronn, the entrepreneur Dieter Schwarz (LIDL, Kaufland, PreZero) is currently being referred to in the media as “the king of Heilbronn” in his role as a local patron and founder (Dieter Schwarz Foundation). This article takes the case study of Heilbronn as a starting point and analyses some urban power relations in the context of philanthrocapitalist activities in the city. Empirically, perspectives from the residents of Heilbronn are taken up on the basis of memes, audio collages and interview mapping, which scrutinise the relationship between the city and the founder Dieter Schwarz. This raises fundamental questions about dynamics in urban power relations that need to be critically focussed on, especially in less prominent cities.

Este ensayo analiza la economía creativa en Nicaragua, destacando el rol estratégico de las Instituciones de Educación Superior (IES) en su fomento. Basado en instrumentos científicos y literatura especializada, aborda principios clave del desarrollo social. El Gobierno de Nicaragua ha creado la referencia legal de la economía creativa mediante el Decreto Presidencial N° 06-2021 que reformó la Ley 290 “Ley de organización, competencias y procedimientos del poder ejecutivo” (GRUN, 2021). Se creó la Secretaría de Economía Creativa y Naranja con lo cual se impulsó la Comisión Nacional de Economía Creativa, incorporando al Consejo Nacional de Universidades (CNU) y a las IES como actores clave (Nicaragua Creativa, 2023). La investigación examina la contribución de las IES en los procesos de innovación, se analizan los tipos de innovación predominantes y se proponen estrategias para optimizar la gestión del conocimiento, subrayando el papel de las IES como catalizadores del desarrollo socioeconómico de Nicaragua.

Este estudo teve como objetivo realizar uma trilha de aprendizagem sobre o tema câncer em escolas de ensino médio, levando os estudantes para o laboratório de Anatomia e Patologia da Universidade. A iniciativa buscou integrar teoria e prática, abordando temas relacionados ao câncer, com foco em conceitos gerais, mutações, formação de células tumorais, carcinoma de intestino, câncer de mama, útero e ovários. O método envolveu a colaboração entre bolsistas dos cursos de Biomedicina, Enfermagem, Farmácia e professores dos respectivos cursos. Previamente, os temas foram discutidos e trabalhados em sala de aula. Posteriormente, as atividades práticas foram realizadas no laboratório da universidade, organizadas em estações temáticas de quinze minutos cada. A abordagem seguiu o modelo de pesquisa-ação colaborativa, promovendo uma relação horizontal entre todos os participantes e facilitando a troca de saberes. Participaram da atividade oito escolas, que envolveram 184 alunos e 8 professores. A metodologia aplicada demonstrou eficácia já que 80,4% dos estudantes disseram que evoluíram no seu conhecimento, ainda 89,7% dos alunos e 75% dos professores participantes relataram que as atividades atenderam ou superaram suas expectativas, destacando a importância do intercâmbio de conhecimentos entre universitários e estudantes do ensino básico. A resposta positiva da comunidade escolar reforça a importância de continuar promovendo o diálogo e a colaboração entre universidade e escola, garantindo a interdisciplinaridade entre acadêmicos de diversos cursos e alunos de ensino básico.

Esta revisão integrativa teve como objetivo explorar os aspectos dinâmicos e neurobiológicos da dependência de jogos em idosos, com foco em identificar fatores predisponentes, impactos cognitivos, emocionais e sociais. Realizou-se uma busca sistemática em bases de dados como PubMed, BVS e Portal de Periódicos Capes, abrangendo publicações entre 2021 e 2025. Os critérios de inclusão foram estudos originais e revisões sistemáticas que abordassem o tema em idosos (≥ 60 anos), em português, inglês ou espanhol. Os estudos indicaram que a dependência de jogos, incluindo videogames, jogos online e jogos de azar, está associada a fatores como solidão, perda de vínculos sociais e dificuldades emocionais. Neurobiologicamente, verificou-se ativação do sistema de recompensa dopaminérgico, alterações no córtex pré-frontal e no núcleo accumbens, similar ao observado em dependências químicas. Por outro lado, o uso moderado de jogos foi associado a benefícios cognitivos, como melhora na memória e na atenção. A relação entre jogos e idosos apresenta uma dualidade. Enquanto o uso controlado pode promover engajamento social e estimulação cognitiva, a dependência surge como um fator agravante de vulnerabilidades pré-existentes. As mudanças neurobiológicas observadas refletem o impacto dos jogos como estímulos altamente reforçadores, especialmente em indivíduos com alterações na plasticidade cerebral relacionadas ao envelhecimento. A dependência de jogos em idosos é um fenômeno multifatorial que combina aspectos dinâmicos e neurobiológicos.

O direito à educação inclusiva das pessoas com deficiência de acordo com o Estatuto da Pessoa com Deficiência (Lei nº 13.146/2015) é o tema-chave deste artigo. Propôs-se como objetivo geral, verificar como o Estatuto da pessoa com deficiência garante o direito à educação inclusiva aos deficientes, historicamente excluídos do ambiente escolar. Para tanto, essa pesquisa compõe-se de uma análise de eixos estruturantes do referido direito, em sintonia com o contexto sóciohistórico de exclusão do sistema educacional e o movimento sociopolítico de inclusão socioeducacional, que influenciaram decisivamente a normatização deste direito fundamental. Este Estatuto possibilitou a institucionalização e a organização no âmbito escolar e universitário do direito à educação a essas pessoas, consolidando diversos eixos considerados estruturantes, como o direito a um sistema educacional inclusivo, a um projeto político-pedagógico inclusivo e a um atendimento por profissional especializado, entre outros. Este artigo baseia-se em pesquisa bibliográfica e documental, tendo como referências, além do Estatuto da Pessoa com Deficiência, categorias teóricas que trabalham questões fundamentais acerca da sociedade e da educação. Documentos construídos em âmbito internacional acerca da temática educação inclusiva e o acervo legislativo nacional que trata da referida temática. Este trabalho confirma/infere que o Estatuto garante a acessibilidade e a inclusão plena da pessoa com deficiência à Educação Inclusiva. Além de reconhecer a educação como um direito humano e social fundamental, o qual deve ser garantido pelo Estado, pela escola e pela sociedade.
In Search of an Elementary Proof for Fermat's Last Theorem

Fermat’s Last Theorem states that the equation x n + y n = z n has no solution for x, y and z as positive integers, where n is any positive integer > 2. Taking the proofs of Fermat and Euler for the exponents n = 4 and n = 3, it would suffice to prove the theorem for the exponent n = p, where p is any prime > 3. We hypothesize that r, s and t are positive integers satisfying the equation r p + s p = t p and establish a contradiction in this proof. We include another Auxiliary equation x 3 + y 3 = z 3 and connects these two equations by using the transformation equations. On solving the transformation equation we prove rst = 0, thus proving that only a trivial solution exists in the main equation r p + s p = t p .
