UV induced changes in bismuth oxychloride–filled polycarbonate composite films2023 •
Bismuth oxychloride (BiOCl) filled polycarbonate (PC) composite films have been prepared at five different filler levels (FLs); that is, at 0, 5, 15, 25 and 35 wt.% (of BiOCl in PC) by using solution casting method.These composites were irradiated with UV - C radiation of wavelength 254 nm for four hours, and were studied before and after UV-C irradiation by using UV-Visible spectroscopy, optical photoluminescence, XRD, SEM, AFM, DSC and TGA. The various optical parameters, such as absorbance, transmittance, reflectance, penetration depth, extinction coefficient, refractive index, optical conductivity as well as the imaginary and real components of the dielectric constant have been studied with respect to wavelength. The fluorescence peaks of the prepared composites showed three emission peaks for pristine PC, at wavelengths 415 nm, 440 nm and 467 nm, and the emission peak intensity increases with an increase in filler level and exposure time to UV irradiation. There is a structural transformation of the sample, from amorphous nature of PC to the crystalline nature of BiOCl filled PC composite samples, which has been confirmed by XRD technique; the degree of crystallinity has increased with an increase in FL. SEM images confirm that surface morphological changes take place due to an increase of BiOCl content in the PC matrix with an increase in FL. The uniform distribution of BiOCl in PC has been confirmed by observing the AFM images. There are no major changes observed in ATR-FTIR peaks of the composites, except at 400-470 cm-1, before and after UV-C irradiation. DSC reveals that the glass transition temperature of the BiOCl filled PC composites decreases when compared to pure PC, both due to incorporation of BiOCl in PC as well as due to UV-C irradiation. A single step decomposition phenomenon is observed from the TGA curves, and pristine PC has greater mass loss and thermal stability among all the filled and irradiated BiOCl filled PC composite films.

Development of the city plan of ancient Sinope: Infrastructure as ideology2024 •
Strabo’s famous description of ancient Sinope in the late 1st century BC has long served as the most vivid image of the ancient town, although it provides no useful information regarding the city’s plan and organisation. The combined evidence of the grid-like plan of the mediaeval town, the Milesian colonial heritage of the city, and an inconclusive textual tradition has led scholars to consider the Sinope plan as an example of a Hippodamian city. This paper proposes that, rather than a simple case of an established type, the city plan of Sinope was dynamic and responsive to changing ideas about the nature and extent of the community, the relationship of the urban-rural-port community, and the ideological underpinnings of community governance.

Metadiscourse: The evolution of an approach to texts2022 •
Metadiscourse is the commentary on a text made by its producer in the course of speaking or writing, revealing something of how communication involves the personalities, attitudes and assumptions of those who are communicating. It offers a framework for understanding communication as social engagement and helps reveal how writers and speakers consider their audience in creating texts. This paper uses a bibliometric analysis to trace the growing interest in metadiscourse since its early incarnations in the 1980s. To do so we analysed all 431 papers relating to metadiscourse in the core collection of the Web of Science between 1983 and 2020, dividing the corpus into two periods following the massive increase in interest after 2006. We identify which topics have been most prevalent, which authors and publications most influential and which disciplines and journals most active in citing the metadiscourse literature. The findings show the importance of academic and business writing, cross-disciplinary, language and genre studies, and the increasing predominance of an interpersonal model. These findings may be of interest to those working in discourse analysis and the study of social interaction.

Automated Timetable Generation using Genetic Algorithm2020 •
Timetable generation is a very burdensome and time consuming task. This is usually done ‘by hand’, taking several days or weeks of iterative repair. Timetable generation is the NP-hard problem, which is very difficult to solve using conventional methods. A highly constrained timetabling problem can also be solved by evolutionary techniques. We must determine an acceptable assignment of the time slots and rooms to the courses based on a variety of their requirements. This project will try to reduce the difficulties of generating timetable by using Genetic Algorithm. By using Genetic algorithm, the time required to generate time table will be reduced and the generated timetable will be more accurate, precise and free of human errors. Main goal is to minimize the number of conflicts in the timetable. System generates timetable for each class and faculty, in keeping with the availability calendar of teachers, availability and capacity of physical resources (such as classrooms, laborator...

Marketing digital, es la aplicación de estrategias de comercialización llevadas a cabo en los medios digitales, También se define como el marketing interactivo, que se realiza usando tecnologías digitales con el fin de alcanzar y crear prospecto de cliente en consumidores. El objetivo principal del marketing digital es llegar a un público con el fin de satisfacer algunas necesidades, y de esta forma aumentar las ventas del servicio o producto que se está emprendiendo, todo esto aplicando a la manera más fácil y rápida de acceder, como lo es la tecnología. El beneficio de manejar Marketing Digital, es el constante cambio de esta práctica, ya que evoluciona de forma constante, un ejemplo claro se ve a comienzos de esta aplicación, en sus inicios Marketing Digital se refería especialmente a hacer publicidad para dichos clientes, pero al pasar de los años las nuevas innovaciones, las nuevas herramientas han hecho que el campo del Marketing Digital se expanda. Hasta cierto punto de que no solo las grandes compañías tengan acceso y manejo de esta herramienta, sino también pequeños emprendedores que a diario van surgiendo. El implemento de nuevas herramientas como aplicaciones para dispositivos móviles, entre otras ha permitido mucho más el acceso y el manejo del marketing digital. El Marketing Digital nos brinda la capacidad de saber Qué y Cómo vender, de esta forma hablamos de las 3P que maneja esta práctica: Procesos, pruebas y personas. Haciendo un resumen de el significado que tiene cada una vemos que las 3P, cuando se habla de proceso se refiere a la atención que recibe el cliente, ya sea inmediata o demorada y la información brindada debe satisfacer las dudas de nuestro cliente, en prueba podemos decir que es normal encontrar clientes que tengan miedo de que el producto no satisfaga su necesidad (ya sea que no se vea como en la presentación, o que la calidad no sea la especificada), por eso una buena atención brindada a nuestro cliente se refleja en una buena recomendación, por otra parte para nuestra tercera P que hace referencia a las personas, se refiere a los vendedores, el Marketing busca que éste cause impresión, que deje huellas en el cliente ya sea entrando en contacto personal u online, esta impresión se causa entrenando al personal de trabajo informándolos bien en el producto a vender, para que así este brinde un buen asesoramiento y hacer que el cliente se sienta seguro y motivado a obtener el producto.

Profil Insân Kâmil Dalam Perspektif Pendidikan Islam2022 •
Abstrak: Artikel ini membahas tentang pengenalan terhadap sosok insan kamil dalam bingkai filsafat pendidikan Islam. Dengan menggunakan metode library research, penelitian ini memberikan analisis tentang peran pendidikan Islam dalam pembentukan insan kamil. Dalam operasionalisasinya, pendidikan Islam merupakan proses transformasi dan internalisasi ilmu pengetahuan serta nilai-nilai pada diri anak melalui penumbuhan dan pengembangan potensi fitrahnya guna mencapai keselarasan dan kesempurnaan hidup dalam segala aspeknya. Upaya untuk mewujudkan insân kâmil sejalan dengan pembinaan manusia seutuhnya dalam kualitas pribadi Muslim sejati sebagaimana yang diinginkan dalam tujuan pendidikan Islam. Dengan demikian, konsepsi tentang insân kâmil merupakan produk intelektualisme yang berharga dan bernilai tinggi bagi pengembangan pemikiran kefilsafatan pendidikan Islam, terutama guna melakukan reorientasi tujuan pendidikan Islam.Kata Kunci: pendidikan Islam, manusia sempurna, tasawuf, filsafa...
