Mathematical Model for Image Restoration Based on Fractional Order Total Variation

This paper addresses mathematical model for signal restoration based on fractional order total variation (FOTV) for multiplicative noise. In alternating minimization algorithm the Newton method is coupled with time-marching scheme for the solutions of the corresponding PDEs related to the minimization of the denoising model. Results obtained from experiments show that our model can not only reduce the staircase effect of the restored images but also better improve the PSNR as compare to other existed methods

Closed flow solar dehydration with the use of silver nanoparticles: Application for the production of Pouteria lucuma flour

In this research, a closed-flow solar dehydrator with a refrigeration moisture extraction system was evaluated, likewise, the dehydration temperature time was optimized by evaluating three types of heat transfer fluids. The dehydration equipment included devices to absorb thermal energy from incident sunlight, such as a trombe wall and a parabolic cylindrical collector, and a thermo bank system. In addition, the influence of three types of heat transfer fluids (water, oil and oil nanofluidþsilver nanoparticles) was evaluated. This dehydration system was applied to process the Pouteria lucuma fruit. The results indicate the reduction of the dehydration time by 58.19% using nanofluid. This treatment prevents the modification of the physicochemical properties of the product and helps preserving its organoleptic propertiesinfo:eu-repo/semantics/publishedVersio

Enseñanza del lenguaje a través de la literatura: un estudio basado en ELT

The present study aims to: firstly, highlight the effectiveness of using literature in ELT classes in an interesting and innovative manner in Pakistan; secondly, to help language teachers develop a thoughtful and principled approach to using literature in the language classroom; thirdly, to provide teachers with the tools for developing their own classroom materials and for using these materials in a way that is relevant to their learners’ needs. This paper explores the text of ‘Good Bye Mr. Chips’, a famous novel by James Hilton (1934) for teaching at the Intermediate level. For the analysis of data, insights are taken from the works of Dubin & Olshtain (1977), Collie & Slater (1987) and Robinette. B. W (1978). It was found that activities like role plays and a lot of pair work and group work not only caused reduction in anxiety level of students but also increased their level of interest and enthusiasm. It also concluded that for facilitating language teaching and learning, the formation of a variety of activities based on learners’ needs from carefully and properly selected texts is unavoidable. Future researchers can exploit similar literary texts following the same frameworks for language teaching purposes.El presente estudio tiene como objetivo: en primer lugar, destacar la eficacia del uso de la literatura en las clases de ELT de una manera interesante e innovadora en Pakistán; en segundo lugar, ayudar a los profesores de idiomas a desarrollar un enfoque reflexivo y basado en principios para utilizar la literatura en el aula de idiomas; tercero, proporcionar a los maestros las herramientas para desarrollar sus propios materiales de clase y para usar estos materiales de una manera que sea relevante para las necesidades de sus alumnos.

Indução, fortificação e primazia do inglês como meio de instrução na primária

Having influenced by the British linguistic superiority, English bequeathed to people of India. Consequently, it got into some of the elite class. Due to the frequent use of English in science and technology and military elites it ran into higher education first then it was considered as medium of instruction at school level too. The current study investigated into the perceptions of the primary school teachers about induction, fortification and primacy of the English language as a medium of instruction in Vehari district. The population of the study were all the primary school teachers of Vehari region while sample of the study selected from all the city schools as well as from surrounding villages. Now a days, English is one of the main and compulsory subjects in Pakistan and was declared as a medium of instruction at school level officially in 2009 and college levels. But teachers at most of the schools practice code-switching while teaching English in the classrooms. For the last five years, English medium of instruction is now in practice, so keeping all the reviewed in the literature ahead, the current study attempted to examine the teachers’ reflections about effects of English language as a medium of instruction at elementary level by surveying about the use of English language as medium of instruction at primary level. The earlier studies reviewed mostly about the implementation of English as a medium of instruction particularly regarding the hurdles and obstacles. As linguists working in language teaching in the classroom setting have meaningfully extended the scope of their research to redress the fundamental areas of classroom practices connected with teaching/learning of English as a medium of instruction. Moreover, the current study has significant suggestions for educational research for pointing out the loopholes and drawbacks in terms of English language implementation as instructional goal. The data was analyzed using SPSS version 21. The study concluded with some suggestions and pedagogical implication to the Policy makers, higher authorities and National accreditation for teacher education in Vehari and Pakistan.Habiendo influido por la superioridad lingüística británica, el inglés legó a la gente de la India. En consecuencia, entró en parte de la clase de élite. Debido al uso frecuente del inglés en la ciencia y la tecnología y en las élites militares, primero se introdujo en la educación superior y luego se consideró también como medio de instrucción en el nivel escolar. El estudio actual investigó las percepciones de los maestros de escuelas primarias sobre la inducción, el enriquecimiento y la primacía del idioma inglés como medio de instrucción en el distrito de Vehari. La población del estudio fueron todos los maestros de escuela primaria de la región de Vehari, mientras que la muestra del estudio se seleccionó de todas las escuelas de la ciudad, así como de las aldeas vecinas. Hoy en día, el inglés es una de las materias principales y obligatorias en Pakistán y se declaró oficialmente como un medio de instrucción en el nivel escolar en 2009 y en el nivel universitario. Pero los maestros en la mayoría de las escuelas practican el cambio de código mientras enseñan inglés en las aulas. Durante los últimos cinco años, el medio de instrucción en inglés está ahora en práctica, por lo que manteniendo todo lo revisado en la literatura a continuación, el estudio actual intentó examinar las reflexiones de los maestros sobre los efectos del idioma inglés como medio de instrucción a nivel elemental mediante una encuesta sobre el uso del idioma inglés como medio de instrucción en el nivel primario. Los estudios anteriores revisaron principalmente sobre la implementación del inglés como medio de instrucción, particularmente en relación con los obstáculos y obstáculos. A medida que los lingüistas que trabajan en la enseñanza de idiomas en el aula, han ampliado significativamente el alcance de su investigación para corregir las áreas fundamentales de las prácticas en el aula relacionadas con la enseñanza / aprendizaje del inglés como medio de instrucción. Además, el estudio actual tiene sugerencias importantes para la investigación educativa para señalar las lagunas e inconvenientes en términos de la implementación del idioma inglés como objetivo educativo. Los datos se analizaron utilizando la versión 21 de SPSS. El estudio concluyó con algunas sugerencias e implicaciones pedagógicas para los responsables de las políticas, las autoridades superiores y la acreditación nacional para la formación docente en Vehari y Pakistán.Tendo influenciado pela superioridade lingüística britânica, o inglês legou a pessoas da Índia.

Bibliometric analysis in Scopus of scientific production on the relationship between periodontitis and gastrointestinal cancer (2014 - 2023)

Recent studies have suggested that some opportunistic periodontal pathobionts have oncogenic properties. However, few bibliometric studies investigate the relationship between periodontitis and gastrointestinal cancer. This bibliometric study aimed to analyze these epidemiological studies conducted between 2014 and 2023 to guide future research. In March 2024, the Scopus database was explored. The articles selected were subjected to a bibliometric analysis of study designs, trends in annual scientific production, and networks of collaboration among countries. Furthermore, the most outstanding countries, academic institutions, authors and journals with the most significant number of publications and the top most cited articles were analyzed. For this purpose, Microsoft Excel, SPSS and VOSviewer 1.6.20 were used. A total of 123 documents were included for analysis. China contributed the most significant number of publications (33 articles) and the United States had the most significant number of citations (2709). Weimin Ye (h-index:81) and Dominique Michaud (h-index:73) were the most prolific authors (5 articles); Dominique Michaud also had the most citations (470). International Journal of Cancer was the journal with the highest number of articles published (6), in addition to being the publication that had the most citations of these articles (409). Tufts University in the United States had the highest number of citations. Between 2014 and 2023, 123 articles on the relationship between periodontitis and gastrointestinal cancer were published. The largest scientific production was found in China, and the most cited articles were those from the United States. Likewise, the research design most commonly used was the cross-sectional type

Reclamando la voz femenina: un análisis de la transitividad de los “días sin carne”.

This study focuses on Suleri’s (1991) “Meatless Days” as this memoir dexterously overthrows the male hegemonic history by reconstructing alternative feminist scripts. To analyze the text, this study relies upon the theoretical stances presented by Bakhtain (2010) and Beauvoir (1988) as these frameworks -opposed to male language- demand a new style of writing. The analysis reveals that material processes are more dominant. These processes are mainly associated with Sara who is engaged in a futile attempt of verifying her nativity.Este estudio se centra en los "Días sin carne" de Suleri (1991), ya que esta memoria derriba con destreza la historia hegemónica masculina mediante la reconstrucción de guiones feministas alternativos. Para analizar el texto, este estudio se basa en las posturas teóricas presentadas por Bakhtain (2010) y Beauvoir (1988), ya que estos marcos, opuestos al lenguaje masculino, exigen un nuevo estilo de escritura. El análisis revela que los procesos materiales son más dominantes. Estos procesos están asociados principalmente con Sara, que está comprometida en un intento inútil de verificar su natividad

Estilística feminista: Representantes femeninas en historias contemporáneas de escritores paquistaníes.

The purpose of the present study is to investigate how women are represented in the stories of Pakistani writers. Current research also explores whether the author's genre has any influence on the vocabulary he uses. The proposed study is qualitative in nature. The results also revealed that male Pakistani writers are more sexist in their vocabulary to portray female characters compared to female writers. Future researchers can explore the same data by following the remaining two: sentence and discursive levels of the Mills model (1995). The present study can also be extended to compare two types of genre as writers by future researchers.El propósito del presente estudio es investigar cómo están representadas las mujeres en los cuentos de los escritores paquistaníes. La investigación actual también explora si el género del autor tiene alguna influencia sobre el vocabulario que usa. El estudio propuesto es de naturaleza cualitativa. Los resultados también revelaron que los escritores masculinos pakistaníes son más sexistas en su vocabulario para retratar personajes femeninos en comparación con los escritores femeninos. Los futuros investigadores pueden explorar los mismos datos siguiendo los dos restantes: niveles oracionales y discursivos del modelo de Mills (1995). El presente estudio también puede extenderse para comparar dos tipos de género como escritores por parte de los futuros investigadores.&nbsp
