Removal of Pharmaceuticals and Personal Care Products from Water and Wastewater

Uncategorized

Authors: Meenu Bose

Abstract: Pharmaceuticals and personal care products (PPCPs) have been among the emerging contaminants of water and wastewater systems in the recent years. These substances have found their way into the environment on a continuous basis as they are widely used and they are not fully eliminated in the traditional treatment procedures. Although in extremely low levels, their long-term occurrence and biological effects may be hazardous to aquatic ecosystems and human health. This review presents the key contributors to PPCPs, their presence in water bodies, physicochemical behaviour, detection methods, and the treatment technologies. Special attention is paid to adsorption processes, the use of advanced oxidation processes, membrane-based treatment, and combined treatment procedures. Further problems and gaps in research and directions are also presented to promote better water management practices.

Review paper on Concrete with Partial Replacement of Fine Aggregate by Copper Slag

Uncategorized

Authors: R Swetha

Abstract: Concrete construction largely depends on natural river sand as fine aggregate. However, continuous extraction of river sand has resulted in serious environmental issues such as riverbed erosion, groundwater depletion, and ecological imbalance. At the same time, copper industries generate large quantities of copper slag as an industrial waste, which poses disposal and environmental challenges. This experimental study focuses on evaluating the suitability of copper slag as a partial replacement for fine aggregate in concrete. Concrete mixes were prepared by replacing river sand with copper slag at proportions of 0%, 10%, 20%, 30%, 40%, and 50% by weight. The fresh properties, strength characteristics, and selected durability parameters of concrete were studied. The results show that concrete containing copper slag exhibits improved strength and durability up to an optimum replacement level of about 20–30%. Beyond this level, a reduction in strength was observed. The study concludes that copper slag can be effectively utilized as an alternative fine aggregate, contributing to sustainable and eco-friendly concrete construction.

An AI-Driven, Explainable Machine Learning Framework For Early Disease Prediction In Healthcare

Uncategorized

Authors: Sreehari K B, Deepakumar M

Abstract: Early disease prediction is a crucial aspect of modern healthcare systems, as it enables timely medical intervention, improves patient survival rates, and reduces long-term healthcare costs. Many chronic and life-threatening diseases such as diabetes, cardiovascular disorders, cancer, and neurological conditions develop gradually and often remain asymptomatic during their early stages. Traditional diagnostic approaches, which rely on clinical rules, physician experience, and fixed statistical thresholds, are often inadequate for detecting these early-stage disease patterns. and neurological disorders progress slowly over time and are often diagnosed only at advanced stages. Late diagnosis significantly reduces treatment effectiveness and increases mortality rates. With the growing global disease burden and aging population, early detection has become a priority in modern healthcare systems. Advancements in healthcare digitization have led to the availability of large-scale medical data, including Electronic Health Records (EHRs), laboratory reports, and medical imaging. These datasets provide valuable insights into patient health patterns and disease progression, enabling the development of predictive models for early diagnosis. With the rapid digitization of healthcare, vast amounts of medical data are generated through Electronic Health Records (EHRs), laboratory test reports, diagnostic imaging, and wearable health devices. This has created opportunities for Artificial Intelligence (AI) and Machine Learning (ML) techniques to analyze complex and high- dimensional medical data efficiently. Existing AI- based disease prediction systems have demonstrated improved accuracy compared to conventional methods; however, many of these systems suffer from limitations such as reliance on single-modal data, centralized data storage, poor generalization across healthcare institutions, severe class imbalance, and lack of interpretability. This project proposes an AI-based early disease prediction framework that addresses these limitations through the integration of multimodal clinical data, privacy-aware learning mechanisms, imbalance-sensitive training strategies, and explainable AI techniques. The proposed system learns complex patterns from longitudinal patient data and generates calibrated risk scores to support early diagnosis and preventive care. By improving transparency, robustness, and clinical trust, the proposed framework aims to provide an effective and scalable solution for early disease prediction in real-world healthcare environments.
