pyParaOcean: A System for Visual Analysis of Ocean Data

Visual analysis is well adopted within the field of oceanography for the analysis of model simulations, detection of different phenomena and events, and tracking of dynamic processes. With increasing data sizes and the availability of multivariate dynamic data, there is a growing need for scalable and extensible tools for visualization and interactive exploration. We describe pyParaOcean, a visualization system that supports several tasks routinely used in the visual analysis of ocean data. The system is available as a plugin to Paraview and is hence able to leverage its distributed computing capabilities and its rich set of generic analysis and visualization functionalities. pyParaOcean provides modules to support different visual analysis tasks specific to ocean data, such as eddy identification and salinity movement tracking. These modules are available as Paraview filters and this seamless integration results in a system that is easy to install and use. A case study on the Bay of Bengal illustrates the utility of the system for the study of ocean phenomena and processes.Comment: 8 pages, EnvirVis202

Sustainable Materials for Water Treatment: A Comprehensive Review

The increasing apprehension regarding water shortage and environmental contamination has heightened the pursuit of sustainable remedies in the field of water treatment. This detailed research examines the use of sustainable materials in water treatment systems. This study aims to examine the pressing demand for environmentally friendly and highly effective methods of water treatment. It comprehensively explores a diverse range of sustainable materials, encompassing both natural biomaterials and sophisticated nanomaterials. The evaluation of key features such as adsorption capacity, selectivity, and regeneration potential is conducted for each material, hence offering valuable insights into their suitability for the purpose of pollutant removal and water purification. The present study provides a critical evaluation of the appropriateness of these sustainable materials by an examination of key criteria like adsorption capacity, selectivity, and regeneration capabilities. The aforementioned attributes, which are crucial for the elimination of pollutants and unwanted substances, highlight the significant contribution of these materials towards the progression of water purification methodologies. In addition to their practical attributes, the analysis explores the ecological consequences and enduring viability of these substances, emphasising the need of mitigating detrimental impacts on natural systems and their associated services. The evaluation further evaluates the environmental consequences and long-term viability of these materials, placing emphasis on their contribution to addressing water-related difficulties. By integrating the most recent research discoveries and technical progress, this literature review not only provides a thorough examination of sustainable materials used in water treatment, but also emphasises potential directions for further investigation and improvement in this crucial field

Characterization of Sustainable Bio-Based Materials for Food Packaging Applications

The increasing environmental issues linked to traditional petroleum-based packaging materials have stimulated a rising curiosity in investigating sustainable alternatives, especially in the field of food packaging. The present study investigates the characterisation of bio-based materials that have the potential to significantly transform food packaging applications. The main aim of this study is to evaluate the feasibility of using these materials as ecologically sustainable substitutes, taking into account their physical, mechanical, barrier, and thermal characteristics. The study process includes the careful selection of a wide array of bio-based materials, such as biopolymers derived from agricultural wastes, chemicals derived from algae, and derivatives of cellulose. The use of a holistic approach allows for a thorough assessment of the sustainability of the materials. The research findings presented in this study make a valuable contribution to the expanding corpus of information pertaining to sustainable packaging options. As there is a growing worldwide focus on reducing plastic waste and minimising ecological impacts, the findings of this research contribute to the promotion of a more sustainable approach to food packaging. These findings are in line with the concepts of a circular and bio-based economy
