Authors: R Sebastin Nesa Raj , B Stanly Jones Retnam , R Dinesh , M Dev Anand , J Edwin Raja Dhas
Published: October 2024

Biodiesel is a renewable, locally generated fuel made from vegetable oils, trans fats, or recycled restaurant grease for use in diesel automobiles and other diesel-powered equipment. The physical qualities of biodiesel are comparable to those of petroleum diesel. Biodiesel is used in compression-ignition engines in the same way as petroleum diesel. Biofuel can be made from biomass, but according to the Indian National Policy on Biofuels, biofuel extraction from edible oils is not permitted because it would result in a massive increase in consumer goods prices and perhaps lead to product scarcity. Hence, there is a need to search for alternative biofuel so that it does not affect our nation's national policy. Recently there has been a drastic increase in the consumption of chicken grown in farms. There is a huge problem in disposing of their waste. One major difficulty in waste treatment is poultry manure, often known as slaughter waste. This waste is sometimes dumped on wastelands, roadsides, and the banks of rivers, lakes, and ponds. This creates more sanitary problems for society. According to polls, poultry feces begin to decompose in around three hours. The odor of butcher's waste causes a lot of pollution in the air, as well as an increase in the density of bacteria in the atmosphere. Measures have been taken by the government for the safe disposal of these wastes. One of the major ways of disposal is to recycle this chicken slaughter waste in a useful manner so that it can serve society in a positive way. This could be done by converting this waste into fuel through various processes such as rendering, hydrolysis, extraction, acid esterification, alkaline transesterification, and finally by the extraction process. This produced fuel could be blended with existing diesel in varying concentrations and used in diesel engine-powered vehicles. In this work, the fuel is extracted from the chicken waste and blended with pure diesel and an Al2O3 additive in various proportions. These combinations are then tested on a single-cylinder diesel engine for fuel consumption and emission analysis. The results exhibited an overall better performance when compared to pure diesel.

Authors: Biswas Debarghya , Tiwari Ankita
Published: October 2024

Insect monitoring techniques are often labor-intensive and need significant resources for identifying species after manual field traps. Insect traps are usually maintained every week, leading to a low temporal accuracy of information collected that impedes ecological analysis. This study introduces a handheld computer vision device to attract and detect real insects. The research explicitly proposes identifying and categorizing species by imaging live species drawn to a camera trapping. An Automatic Moth Trapping (AMT) equipped with light elemnets and a camera was developed to draw and observe insects throughout twilight and nocturnal periods. Moth Classification and Counting (MCC) utilizes Computer Vision (CV) and Deep Learning (DL) evaluation of collected pictures and monitors. It enumerates insect populations while identifying moth species. Over 48 nights, more than 250k photos were captured, averaging 5.6k daily. A tailored Convolutional Neural Networks (CNN) was developed on 2000 labeled photos of live insects across eight distinct categories. The suggested computer vision method and methodology have shown encouraging outcomes as an economical option for automated surveillance of insects.

Authors: Vij Priya , Prashant Patil Manisha
Published: October 2024

Due to the fast advancement of big data, applying Machine Learning (ML) techniques to detect Soil Pollution (SP) at Potentially Contaminated Sites (PCS) across many sectors and regional sizes has emerged as a prominent research focus. The challenges in acquiring essential indices of SP sources and routes result in present methodologies exhibiting low predictive accuracy and an inadequate scientific foundation. This study gathered environmental data concerning heavy metal and organic contamination from 200 PCS across six representative sectors. Twenty-one indices derived from fundamental data, potential SP from products and materials, SP efficacy, and the migrating capability of SP were employed to build the SP detection index method. The research integrated the score into the new characteristic group, including 11 indicators using consolidation computation. The newly selected feature subset was utilized for training ML designs, including Random Forests (RF), Support Vector Machines (SVM), and Multilayer Perceptrons (MLP), and evaluated to ascertain its impact on SP recognition methods. The study findings indicated that the four newly developed indices by feature fusion exhibit an association with SP comparable to that of the original index. The component analysis suggests that several indices related to fundamental information, contamination potential from products and raw materials, and SP prevention levels significantly influence SP to varying extents. The index of the migratory capability of soil contaminants has minimal influence on the classification job of SP detection inside PCS. This research introduces a novel technological approach for identifying SP via big data and ML techniques while offering an overview and scientific foundation for PCS's environmental administration and SP mitigation.

Published: October 2024

The process of speech generation is intricately linked with cognitive styles, linguistic culture, and pragmatic factors. Intercultural communication practices seek to embrace a new mindset, assimilate into a different linguistic culture, and understand the perspective of its inhabitants. Grammatical constructions convey substantial linguistic, cultural, and cognitive insights about native speakers. This article aims to enhance scientific comprehension of the correlation between language grammar, socio-cultural reality, and the cognitive style of native speakers in the context of teaching English and French to native Russian speakers. It is essential to highlight the cognitive and linguocultural aspects of grammatical phenomena, emphasizing that grammar represents not only a set of intricate sentence construction rules but also embodies the result of the historical development of consciousness within a linguistic culture. Notably, the disparities between linguistic cultures are visibly apparent when examining aspectual and temporal meanings.

Authors:   Russian State University for the Humanities, Pyatunina Anastasiya A.
Published: October 2024

The article is devoted to a diachronic review of popular German songs, which are an inexhaustible source of socio-political, historical and cultural heritage of Germany. A detailed study and deep understanding of the song heritage of any country contributes to a more effective mastery of a number of disciplines, among which a foreign language occupies one of the leading places. The author of the article pays special attention to the study of lexical, stylistic (artistic), thematic and functional features which reveal the cultural and historical wealth that the special language of a song in general and a German song in particular has. Using comprehensive, historical-cultural and didactic approaches to the song analysis, the author attempts to trace the relationship between a song in a foreign language and the sociocultural context of a certain historical era. At the same time, the author proves that the study of such a relationship is a cognitive process aimed at understanding the history and culture of the country of the language being studied. And the text of the song, being a type of a poetic text, is a complex phenomenon that includes historical, cultural and linguistic aspects. The diachronic review used in the article allows us to consider the qualitative changes that a popular piece of music – including a sung narration – undergoes over a certain period of time.

Published: October 2024

Mastery of arithmetic operations is fundamental for students pursuing science education, as these skills are essential in solving complex problems in physics, chemistry, and biology. However, gaps in students' arithmetic proficiency can hinder their academic and professional development. This study aims to examine the arithmetic skills of pre-service science teachers in solving mathematical problems across six domains: addition, subtraction, multiplication, division, exponentiation, and mixed operations. A total of 37 short-answer questions were administered, and the results were analyzed by domain. The findings indicate that students demonstrate proficiency in basic operations involving whole numbers, particularly in addition and subtraction. However, challenges persist in the areas of fractions, decimals, and mixed operations, where accuracy rates were notably lower. These gaps in understanding may affect students' ability to apply mathematical concepts in their science courses and future teaching roles. The study's limitations include a focus on quantitative results without exploring the cognitive processes behind student errors. Future research should investigate intervention strategies to address these weaknesses, potentially through targeted instructional approaches or the use of technology to enhance learning outcomes

Over the past two decades, Australia’s higher education sector has experienced rapid growth, driven by the establishment of the demand-driven funding system for domestic enrolments in 2010 and increased international enrolments. This expansion has led to an increase in both domestic attainment and internationalisation, positioning higher education as a critical sector within the national economy. However, despite this growth, persistent challenges around student equity, leadership, and institutional accountability remain. This article explores how the Bradley Review’s reforms and subsequent policies have shaped student access and equity in Australian universities, with a focus on the limitations of existing programs. It also addresses the need for a renewed focus on evidence-based practices, highlighting how leadership can drive meaningful change in the sector. By examining these key issues, the article contributes to ongoing debates about the role of universities in social mobility and enhancing equitable outcomes.

El crecimiento poblacional urbano en Latinoamérica está acompañado de un proceso expansivo disperso de las ciudades y mayor consumo energético. Las normativas urbano-edilicias poseen potencial para mitigar estas problemáticas. Mediante un relevamiento y diagnóstico de normativas se estudiaron los marcos regulatorios urbano-edilicios de los seis municipios del Área Metropolitana de Mendoza (AMM), posibilitando cartografiar zonificaciones de usos del suelo y analizar estadísticamente los indicadores municipales comunes con un árbol de decisión para identificar su influencia desde una perspectiva energética. El trabajo permitió reconocer heterogeneidad de indicadores, diversos rangos parcelarios por municipio con baja ocupación del suelo de media y baja altura edilicia, en detrimento del objetivo del Plan Provincial de Ordenamiento Territorial (PPOT) de una ciudad compacta y sostenible. Finalmente, la investigación identificó: fragmentación administrativa, desarticulación normativa e incipiente acceso a la información; manifestando la necesidad futura de acordar entre municipios un ajuste de indicadores hacia la consecución del objetivo mencionado.

En el presente trabajo se ensaya un método de identificación de brisas marinas en la isla de Mallorca, basado en el análisis de los datos de viento provenientes de estaciones situadas en un ámbito terrestre y marino, correspondientes a dos unidades regionales: la bahía meridional de Palma y la bahía septentrional de Alcúdia. La fuente de datos principal han  sido los mareógrafos terrestres de la red REDMAR (Puertos del Estado), los resultados de cuyo análisis han servido para comprararlos con datos de la boya de Dragonera, de la red REDEX, situada fuera de la zona de influencia de las brisas marinas, así como con datos de la serie temporal de puntos SIMAR, localizados sobre la superficie del mar. Estas tres fuentes se han demostrado útiles para examinar y carácterizar sumariamente el campo de viento de las brisas marinas, un fenómeno atmosférico con una muy alta recurrencia en la isla.
