Supported silver catalysts on titanium dioxide have been synthesized by three different methods to compare catalytic activity in CO oxidation. The catalysts were prepared by the wet impregnation method with 10 mole% of silver. In the first method, the silver catalysts were impregnated on the titanium dioxide nanoparticles (Ag/TNP), while in the second method, the silver catalysts were impregnated on the titanium dioxide nanotubes (Ag/TNT). The third method, the silver catalysts were impregnated on the titanium dioxide nanoparticles before the nanotube process (Ag/TNP-TNT). The Ag/TNP and Ag/TNT catalysts showed highly dispersed silver nanoparticles with an average particle size of less than 5 nm on the surface of titanium dioxide, whereas the Ag/TNP-TNT catalyst exhibited much lower dispersion of silver nanoparticles. The highly dispersed silver on the titanium dioxide resulted in a large number of surface active sites (Ag0). The catalytic activity test found that the Ag/TNT catalysts with the highest number of active sites (2.20 × 1020 atom/g-catalyst) exhibited higher CO oxidation activity than the Ag/TNP and Ag/TNT catalysts with 100% CO conversion at 125°C.

Published: April 2024

The rise of technology has emphasized the importance of identifying altered images and videos to preserve trust and authenticity in digital content. Convolutional Neural Networks (CNNs) have emerged as tools, for tasks like detecting fakes. This study introduces a method for identifying fakes using CNNs. Our strategy involves training a CNN model on a dataset containing both synthetic visuals. The network is structured to learn features that differentiate between manipulated content. We use a mix of layers pooling layers and connected layers to extract and process features from the input data. To strengthen the reliability of our model we employ techniques like data augmentation and transfer learning. Data augmentation includes applying transformations such as rotation, scaling and cropping to the training data to enhance its variety. Transfer learning allows us to utilize trained CNN models and adjust them for deep fake detection purposes. We assess the effectiveness of our approach on datasets. Compare it with existing techniques. Our experiments show that our CNN based method achieves accuracy in spotting fake content in different scenarios. Additionally we examine how well the model withstands attacks and variations, in input data quality.

Authors:   Assistant Professor, Department of Computer Science and Engineering, Tirumala Engineering College, Teja Mr. Y. Vamsi Krishna
Published: April 2024

Forecasting forest fires requires the application of different techniques and instruments to evaluate the likelihood and potential seriousness of a fire starting in a forested region. Elements like drought, extreme temperatures, and human behaviors like bonfires, cigarettes, and pyrotechnics can all play a role in sparking forest fires. Various methods such as statistical examination, AI algorithms, and satellite pictures are employed to gather and dissect data on climate conditions, moisture levels, topography, and other factors that may heighten the chance of a forest fire. Models for predicting forest fires can furnish advanced caution systems to inform officials and locals of potential fire hazards. Predicting forest fires in the future is expected to decrease the impact of fires. This study focuses on developing a system for predicting forest fires, which calculates the likelihood of a fire starting based on various meteorological factors such as location (latitude and longitude) and temperature. The Random Forest regression algorithm was utilized to create this predictive model. Key Words: Forest Fire, Machine Learning, Temparature, Random Forest, Regression
Safe Communication Using Steganography
Authors:   J. J. Magdum College of Engineering, Jaysingpur, Bandgar Prof. Mrs. Seema
Published: April 2024

This research aims to propose a method of safe communication using steganography, which involves hiding information in other information to conceal the fact that communication is taking place. Digital images are one of the most popular file formats used for steganography due to their frequency on the internet. The project focuses on hiding secret information within images using steganography techniques. Different techniques have their respective strong and weak points, and their application requirements vary. The proposed technique allows users to choose the bits for replacement instead of using the least significant bit (LSB) replacement from the images. In this technique, the sender selects a cover image with the secret text or text file, hides it in the image, and sends it to the receiver through a private or public communication network. The receiver retrieves the secret text hidden in the stego-image using the software. This method provides a secure and user-friendly interface for individuals to exchange confidential messages. It leverages the power of image steganography to address the growing need for privacy and confidentiality in digital communication. By hiding messages within images, it ensures a covert and secure means of transmitting information while maintaining the visual appearance of harmless images. Keywords: Encryption, decryption, steganography, safe communication.

Published: April 2024

The article examines the technical and economic aspects of well killing under conditions of abnormal low reservoir pressure (ALRP). The possibility of joint use of compositions for temporary blocking of a productive formation, having different functional abilities to plug fluid-conducting channels, has been studied. Requirements for blocking fluids (BF) for killing during repair works in wells with excess ALRP have been formulated. The results of research and technical solutions in the field of development of viscoelastic systems for temporary blocking of productive formations in wells in conditions above the ALRP are presented. The results of laboratory and bench studies on the development of a gel-forming destructuring polymer-based biosol and fillers are presented. The advantage of using a destructurable biological fluid for temporary blocking of a productive formation in conditions above the maximum pressure limit using chemical reagents belonging to the following groups: polymers, salts, surfactants, acids, alkalis and fillers has been analyzed. The results of determining the mechanical properties of the resulting BF gel are presented. A gel-forming composition has been proposed that has high blocking properties and an optimal formulation of an alkaline destructor that ensures the destruction of the gel based on gammaxan. Formulations of viscoelastic destructurable fluids for killing wells in conditions exceeding the ALRP have been recommended for practical use.

Language ideologies in metaphors: Exploring L2 Saudi students’ conceptualization of language mixing as a language practice
Authors: Alharbi Najlaa
Published: April 2024

This qualitative study aimed to examine the embedded language ideologies within L2 Saudi students’ metaphorical texts to discover their ideological perspectives about language mixing. Using language ideology as a lens of analysis, this study examined 74 metaphorical texts written by undergraduate students to determine their language ideologies. The results revealed that the students held multiple and contradictory language ideologies about language mixing. Students’ language ideologies were found to be an orientation along a language ideological continuum with one end representing the ideology of language mixing as a resource and the other reflecting the ideology of language mixing as a challenge. Some students’ language ideologies may fall somewhere in the middle of this continuum since they expressed conflicting language ideologies, perceiving language mixing as both a valuable resource and a potential challenge. Using language ideologies as a lens to evaluate students' metaphorical texts allowed the different language ideas hidden within the three basic language ideologies to be revealed.  In addition, the study found that the students employed different metaphors to conceptualize language mixing, covering a wide range of areas such as food, drinks, objects, places and activities. The findings suggested that Saudi students’ metaphors and language ideologies are intertwined and mutually influence each other. This study recommends that teachers use conceptual metaphors as a reflective tool to unveil L2 students’ perspectives on academic activities and calls for further research on conceptual metaphors and language ideologies in L2 contexts.
Criminalisation Without an Object: Critical Reflections on the Muslim Women (Protection of rights on Marriage) Act, 2019
Authors: Chaudhary Shraddha
Published: April 2024

The invalidation of triple talaq by the Supreme Court of India triggered the enactment of the Muslim Women (Protection of Rights on Marriage) Act, 2019. The paper demonstrates the superfluous and arbitrary nature of the Act in light of the Supreme Court’s decision to strip triple talaq of its power to repudiate a marriage. Drawing from the rich and varied theories of criminal law in Anglo-American legal discourse, the paper argues that the criminalisation of triple talaq lacks theoretical foundation and is wholly unjustified. Finally, the paper sets the criminalisation of triple talaq within the context of the social and material vulnerabilities of Muslim women, and the political dominance of the right-wing Hindutva in India, arguing that it is likely to cause significant harm by exposing India’s Muslim minority further to the State’s coercive powers. For these reasons, the criminalisation of triple talaq requires urgent reconsideration.
​Article 15 and the Citizenship (Amendment) Act – A Thought Experiment ​
Authors: Sebastian John
Published: April 2024

The Citizenship (Amendment) Act, 2019 (‘CAA’) has been the subject of many constitutional challenges and intense legal debate. Despite this, there has not been sufficient debate on the question of the applicability of Article 15(1)’s non-discrimination clause to the CAA. Article 15(1) of the Constitution prohibits the State from discriminating, inter alia, on the grounds of religion. Since the CAA covers those who are not currently citizens, and Article 15(1) mentions a citizen as its subject, many have argued that Article 15 cannot apply despite the CAA explicitly being grounded on religion. I contest this, and argue that due to the nature of the CAA as a law which determines the conditions of entry into the community of citizens, it must be subject to Article 15(1) (through the ‘conditions of entry’ principle). First, recent Supreme Court jurisprudence has shown that entry conditions cannot be ignored when discussing Article 15(1). Second, I conduct a thought experiment through a hypothetical citizenship law. Through this thought experiment, I demonstrate that to not extend Article 15(1) to the CAA would be illogical and allow the legislature to accomplish indirectly what is impermissible directly. It could deprive that great non-discrimination clause of its vitality through an act of subterfuge. I defend my thought experiment by addressing various arguments on the grounds and subjects of discrimination, the question of numbers, and anti-subordination, and demonstrate that my claim is consistent with the text of Article 15(1). Hence, the CAA should be subject to the rigorous scrutiny of Article 15(1).
Essential Religious Practices' Doctrine as a Cautionary Tale: Adopting Efficient Modalities of Socio-Cultural Fact-Finding
Authors: Dominic Mary Kavita
Published: April 2024

In India, interactions between law and religion have often culminated in fractious, long-standing disputes. To reconcile this tension, a diluted form of legal pluralism was embraced in the post-Independence period. A delicate balance was struck between ‘universal’ state laws and ‘localized’ religious norms. In recent times, this balance has been upended by a judicial application of the ‘Essential Religious Practices’ (ERP) doctrine – a doctrine whereby protection is conferred on beliefs or practices judged ‘essential’ to a religion. In carving out the essential core of a religion, courts in India have retained only those religious norms that conform to the ‘globalizing uniformity’ of state laws. Surpassing a purely legal or constitutional perspective, this paper investigates the socio-cultural consequences emanating from this essentializing discourse. By employing the methodology of critical discourse analysis, it argues that one of the discursive implications of the ERP doctrine has been to undermine the internal autonomy and normative pluralism of religions. In doing so, it has also disregarded their dynamic nature and universalized dominant cultural norms. Perceiving this as a cautionary tale, this paper theorizes that any potential substitute for the ERP doctrine needs to steer clear of the same shortcomings and accord due weightage to the cultural particularities of religious groups. In this regard, the utility of anthropological expertise in enhancing modalities of socio-cultural fact-finding is discussed.
Socio-spatial Consequences of Disturbed Areas Act 1991 on Urbanizing Spaces in Gujarat
Authors: Shrivastava Devansh
Published: April 2024

Segregation on ethnic lines has often manifested in various forms of exclusion and group in equality. The spatial manifestations of violence in globalizing spaces of ‘divided cities’ also exhibit rigid patterns of community based ‘self-sorting’. The communalization of public and private housing with regard to demography has been a significantly pronounced exclusionary crisis in Indian divided cities. This paper, an abridged version of my MPhil thesis, concerns such a unique case. It assesses the impact of Disturbed Areas Act 1991 (‘The Act’) on ghettoisation in Ahmedabad city against the background of mass violence. The paper thus concerns the dynamics of spatial segregation in cities of Gujarat around residential and commercial property disputes. It conducts a socio-legal examination of ten case laws (2002–2021) by responding to the literature on divided cities. It argues that informal zoning practices of community led self-sorting behavior at the ground level, coupled with the Act’s operation (and the demand for its extension as legal protection), disparately impact existing group inequalities pertaining to housing access, afford ability and individual residential mobility in urbanizing spaces.
Understanding Construction of Technologies of (Trans)gender in India Shaped By Mechanisms of Security, Surveillance and Welfare
Authors: Bodwal Kaushal
Published: April 2024

Through this paper, I aim to understand how the notion of surveillance as it functions in state welfare contributes to the construction of transgender identity. By looking critically at welfare mechanisms not only as failures in proper implementation but also as inscribing technologies of security on bodies through surveillance techniques, I try to question the value of state legibility by focusing largely on its relation to the security apparatus. This security apparatus does not simply function through the law but through a host of institutions, particularly psychology and medicine, which allow the state to regulate and employ dominant understandings of gender and transgender selves in the governing processes. In doing so, I rely on transgender narratives of engagement with these fields. I reflect on how the state has dealt with the question of transgender persons more recently through an analysis of the third gender category in NALSA v Union of India, and its transposition to Transgender Persons (Protection of Rights) Act, 2019.
Effect of Enteric Fever on Hematological Cells Parameters
Authors: Rahimee Israr Ullah , Azimee Mohammad Azim
Published: April 2024

Background: Salmonella typhoid and paratyphoid are the agents that cause Enteric fever (Typhoid fever). It is primarily a disease of developing countries because of poor sanitation standards.
Fever is a prominent and well-known feature of the illness that increases steadily to a maximum degree. The hematological criteria of an affected individual are changed by this infectious disease. To ascertain the different hematological cells parameters in our sample population, we conducted the investigation.
Patients and Methodology: The study, which involved 100 Afghans, was carried out at the Nangarhar University Teaching Hospital between June and November of 2022.
A case-control study design was used. Fifty individuals (Cases) who had a confirmed diagnosis of Enteric fever (Typhoid fever) based on typhoid (IgG and IgM) were included in the study. As a control group, fifty healthy individuals with negative typhoid (IgG and IgM) results and no other complaints were included in the study.
For both the case and control groups, a complete blood count was performed. Hemoglobin (Hb), White Blood Cell Count (WBC), and Platelet Count (PLT) are regarded as hematological markers. Every patient was also interviewed, and a questionnaire was employed. Numerous demographic factors were questioned, including sex, age, economic status, level of education, and clinical symptoms. SPSS version 16 was then used to analyze the collected data.
Results. In the current research, over all 100 patients were enrolled (50 were case, and 50 were control group). The mean age± SD of the patients under the study were 38.74±15.22 years. The most common hematological changes observed were; anemia (32%), thrombocytopenia (24%), leukocytosis (8%) & leucopenia (22%). Fever was the most common presenting symptom (78%) and abdominal symptoms were about 38%. Most of the people were of lower socioeconomic state and were uneducated.
Conclusion: This study shows that Enteric fever is bacterial infection and are acquired by enteral route. This disease commonly affects people of low socioeconomical states and those that are uneducated. Fever was the most commonly presenting symptom in these patients. Enteric fever causes changes in the hematological cells parameters which is probably due to bone marrow suppression, which is transient and shows response to therapy.

Dynamical analysis combined with parameter identification for a model of infection in honeybee colonies with social immunity
Authors: Atanasov Atanas , Georgiev Slavi , Vulkov Lubin
Published: April 2024

Several models on honeybee population dynamics have been considered in the past decades, which explain that the growth of beecolonies is highly dependent on the availability of food and social inhibition. The phenomenon of the Colony Collapse Disorder (CCD) and its exact causes remain unclear and here we are interested on the factor of social immunity.
We work with the mathematical model in [1]. The core model, consisting of four nonlinear ordinary differential equations with unknown functions: brood and nurses B, iB, N and iN represent the number of healthy brood, infected brood, healthy nurses, and infected nurses, respectively.
First, this model implements social segregation. High-risk individuals such as foragers are limited to contact only nectar-receivers, but not other vulnerable individuals (nurses and brood) inside the nest. Secondly, it includes the hygienic behavior, by which healthy nurses actively remove infected workers and brood from the colony.
We aim to study the dynamics and the long-term behavior of the proposed model, as well as to discuss the effects of crucial parameters associated with the model. In the first stage, we study the model equilibria stability in dependence of the reproduction number.
In the second stage, we investigate the inverse problem of parameters identification in the model based on finite number time measurements of the population size. The conjugate gradient method with explicit Frechet derivative of the cost functional is proposed for the numerical solution of the inverse problem.
Computational results with synthetic and realistic data are performed and discussed.
Lærerliv i en mangfoldig norsk skole
Authors: Hauge Kåre , Kristin Holmen Heidi , Isaksen Veronica , Leithe-Lajord Markus , Sem Leiv , Taraldsen Eldar
Published: April 2024

I så vel faglitteratur som i offentlig diskurs omtales ofte skolen i entall, som «den norske skolen», som om den var en enhetlig størrelse, sentralisert og uforanderlig. I boken utfordrer vi en slik forståelse og hevder at denne forståelsen ikke nødvendigvis holder stikk i virkeligheten. Skoler utgjør et nettverk av ulikskap og mangfoldighet. Skolen er kontekstuelt forankret i ulike omgivelser, knyttet til geografi, kultur, skolestruktur og skolekultur – alt med betydning for lærerlivet som utspiller seg der.
Vi ønsker med denne boken å fremheve det mangfoldige spekteret av norske skoler, like variert som lærernes egne liv. Vi ønsker å synliggjøre ulike aspekter av denne mangfoldigheten som vi mener er mangelfullt representert i både faglitteratur og lærerutdanning. Å omtale skolen som en enhetlig størrelse kan virke som et svar på forventningen om at alle elever i Norge skal få lik opplæring, uavhengig av hvilken skole de går på. I boken presenteres ideer og kapitler som synliggjør skolens kompleksitet, både i mandat og struktur, og at lærernes yrkesutøvelse av den grunn kan være svært variert.
Boken henvender seg til lærerutdannere, studenter i lærerutdanning, lærere, rektorer og andre som er opptatt av læreryrket og skole.
Cáncer de páncreas
Authors: CORDÓN GRANADOS FERRAN , SAURA PARRAMON MERITXELL
Published: April 2024

Puntos clave
El cáncer de páncreas (CP) es un tumor con una gran letalidad y la sintomatología generalmente es muy inespecífica, incluso silente hasta fases avanzadas, lo que provoca retrasos en el diagnóstico.
Dada la baja supervivencia, es importante estar alerta ante signos de sospecha y se debe disponer de un circuito de derivación rápida para el diagnóstico precoz y el inicio del tratamiento.
El tabaquismo es el factor de riesgo mejor establecido de CP; el riesgo en fumadores se multiplica por dos.
Existe cada vez más evidencia de que el consumo elevado de alcohol contribuye al riesgo de CP.
El aumento de la esperanza de vida y la creciente incidencia de diabetes y de obesidad hacen prever una creciente tasa de CP en un futuro cercano.
El tratamiento quirúrgico y las terapias citotóxicas actualmente disponibles son muy poco efectivas para la enfermedad avanzada.

Objetivo: Avaliar o impacto da realização do exame Papanicolau na identificação precoce da doença e na redução da taxa de lesões de alto grau causadas pelo câncer do colo do útero. Metodologia: O presente artigo trata-se de um estudo de caráter quantitativo e descritivo acerca dos casos de câncer do colo do útero e da importância da detecção precoce na saúde das mulheres no estado da Bahia. Resultados: No Brasil, mais precisamente na região Nordeste, identifica-se cerca de 20 novos casos a cada 100 mil mulheres. Verifica-se que o número de lesões de alto grau identificados em mulheres que realizaram citologia anterior (rastreamento) obtém um percentual menor quando comparado ao número de lesões que foram identificadas em mulheres que não realizavam o exame preventivo anteriomente. Considerações: A partir da realização desse estudo, foi possível compreender a importância da realização periódica do exame Papanicolau e da redução das taxas de lesões de alto grau nas mulheres que realizaram, periódica e anteriormente, a citologia de colo do útero. O que demonstra, efetiva e categorigamente, a capacidade de rastreamento, diagnóstico e melhores prognósticos frente ao combate ao câncer do colo do útero.

The survival of industries in the market involves constantly searching for means to face the challenges of overcoming competitors, retaining current customers and acquiring new ones, optimizing resources, and acting strategically. It is known that to achieve these purposes, they must incentivize innovation by collaborating with external agents such as knowledge institutions, public Institutions for innovation support, startups, and even traditional competitors. This approach, referred to as open innovation, occurs more intensely in industries present in developed countries. In Brazil, open innovation is primarily used by large national or foreign companies, and businesses and public institutions make efforts to disseminate the innovation culture. This work examines how small and large Brazilian industries have been investing in research and development, how they are structured to carry out these processes, and what entrepreneurs have perceived concerning the benefits and difficulties of innovating. To this end, this study evaluated the data from the last three editions of the Survey of Innovation (PINTEC), elaborated by the Brazilian Institute of Geography and Statistics (IBGE). It could be concluded that Brazil needs to make additional efforts to build an effective environment for innovative industries. Brazilian companies remain concerned with short-term survival; most internal efforts are to develop new products, have low interaction with universities, have little knowledge of innovation support mechanisms, and, in general, are highly susceptible to external economic factors.

Este trabalho objetiva revisar e aprofundar a discussão sobre a necessidade da Educação Ambiental (EA) efetiva, trabalhada de modo transdisciplinar, como previsto na lei nº 9.795/99, que estabelece a obrigatoriedade da EA nas escolas, em todos seus níveis, visando à pesquisa, à criação de projetos, à gestão ambiental e à responsabilidade social das escolas. Sob esse prisma, discutimos, neste estudo, o encontro das necessidades ambientais com as leis governamentais referentes à EA e à realidade escolar manifestada, principalmente, em suas estratégias pedagógicas e nos documentos que orientam a Educação Institucional brasileira. Como resultado da análise da discussão, ressaltamos a necessidade de se trabalhar de modo holístico, inter e transdisciplinar, colocando o aprendente como centro do processo ensino-aprendizagem e de sua descoberta como agente transformador do meio, compreendendo sobre a riqueza sócio-cultural-biodiversa de sua região, desenvolvendo suas habilidades específicas, com pertencimento ao local e visão holística de pertencimento ao todo. Para tanto, faz-se necessário investir em formação e uso das tecnologias, para que a educação, como ferramenta, adeque-se ao seu público aprendente do século XXI.
A VIOLÊNCIA NAS RELAÇÕES DE INTIMIDADE ENTRE ADOLESCENTES EM AMBIENTE ESCOLAR: UMA REFLEXÃO À ÓTICA DE BACHELARD
Authors: Silva Vivianne Mendes Araújo , Ribeiro Liana Viana , Penna Lucia Helena Garcia
Published: April 2024

Introdução: Observamos que no relacionamento entre os jovens, podem haver várias formas de violência, tais como agressões psicológicas, físicas e sexuais. O ciúme, o sentimento de posse ou de controle, somado à cultura do machismo atuam nessas relações violentas, que por ocorrerem na fase das primeiras experiências afetivas e sexuais, podem deixar marcas cujo impacto podem repercutir na vida adulta. Nesta concepção, como forma de mudança deste paradigma, trazemos à luz os conceitos de Gaston Bachelard, que aponta para os movimentos sociais, como um valioso artefato visando romper com as barreiras do senso comum, proporcionando a construção de um novo espírito científico frente ao senso comum. No que concerne, estes movimentos sociais, tais conceitos aplicam-se na ótica dos movimentos feministas, como forma de romper com os estereótipos de gênero, defendidos na sociedade atual.  Metodologia: Trata-se de uma pesquisa descritiva, com abordagem qualitativa do tipo reflexão. Tal reflexão emergiu durante a elaboração do trabalho final da disciplina de Filosofia da Ciência e Método Científico em Saúde e Enfermagem, pertencente ao Programa de Pós Graduação em Enfermagem da Universidade do Estado do Rio de Janeiro. (UERJ) Considerações finais: De acordo com Bachelard, a escola é o mais elevado modelo social. Nesta concepção, igualmente a escola deveria tornar a ciência educativa e o ensino socialmente ativo. Portanto, devemos atentar-nos para uma reformulação do ensino, que vise perpassar por tais questões culturais que envolvem os relacionamentos, a fim de promover discussões acerca das questões de violência e de uma cultura de paz. Por conseguinte, compreende-se que a educação em saúde é fundamental nestas situações, e que o conhecimento do fenômeno pelos sujeitos envolvidos permitirá com que este ciclo seja rompido, junto às ações e serviços de saúde de prevenção das situações de violência e de suporte para às adolescentes que já foram expostas a tais situações.

Com o aumento da divulgação sobre a importância do aleitamento materno houve uma ampla investigação de possíveis empecilhos e da busca para suas soluções. Com isso, observa-se um crescimento significativo do número de crianças diagnosticadas com anquiloglossia e, por consequência, no número de frenotomias realizadas. Por mais que seja um procedimento simples, ele ainda possui complicações que, infelizmente, não são tão investigadas. Dessa forma, com as novas evidências que vêm surgindo sobre esse assunto, que por tanto tempo foi deixado de lado, há um novo questionamento no cenário mundial “será mesmo a frenotomia a melhor terapêutica para anquiloglossia?”
