Seasonal Variations of Air Quality Measures In Warri and Effurun, Delta State, Nigeria.
Abstract: Air quality in Urban Cities like Warri and Effurun has been deteriorating over time. The distribution levels of air pollutants in the Warri and Effurun environments may be related to both natural and man-made factors. In addition to evaluating the quality of rainwater with regard to pH, heavy metals (Fe, Pb, Cd, As, Hg, CU, Zn), and some anions (Cl-, NO3-, SO42-, CO32-), this project study aims to investigate, using …

A Comparative Machine Learning Framework for Early Prediction of Liver Cancer Using Clinical Attributes
Abstract: One of the main causes of cancer-related death globally is liver cancer, and improving patient outcomes depends heavily on early detection. However, low contrast, noise, organ similarity, and tumor shape and size variability make it difficult to accurately identify and segment liver tumors from medical imaging. Automated liver cancer diagnosis, segmentation, and prognosis have been greatly improved by recent developments in artificial intelligence (AI), especially deep learning. This work presents …

Groundwater Contamination in Punjab Due to High Levels of Nitrate (NO3 - ) and Its Health Hazards: A Preliminary Report
Abstract: Punjab is facing a crisis due to high levels of heavy metals and nitrate concentration in groundwater of several districts of Punjab. The highest level of NO3 content of 2553 mg/l has been recorded in two villages of Patiala district. The concentration of NO3 in groundwater of seven districts of Punjab has been studied. The maximum content values range from 78.20 in Pathankot to 2553 mg/l in Patiala district, which …

Maternal and Infant Pollutant Exposure through Breastfeeding in Industrial Punjab
Abstract: Because of their lasting presence, bioaccumulation in the food chain and/or potential for transferring to infants through breastfeeding, environmentally persistent chemical pollutants, such as per- and polyfluoroalkyl compounds (PFAs), pesticides, heavy metals and industrial emissions, represent significant public health threats. A study was conducted using a structured questionnaire to gather information about maternal demographics (age, education, marital status), how mothers were exposed to environmental contaminants through occupational activities, the ways …

Prevention of Varicose Veins
Abstract: Varicose veins are abnormal, dilated blood vessels caused by weakening in the vessel wall. Such conditions that increase pressure on the leg veins such as overweight, lack of exercises, hormonal fluctuations during pregnancy and menopause, smoking; constipation or people who have prolonged standing or sedentary position or repeated heavy lifting make veins of legs very weak and develop into varicose veins. Researchers report that a mild care of varicose veins …

A Critical Evaluation of Mercury Contamination in Groundwater of Punjab
Abstract: Groundwater in Punjab State has been over-exploited for irrigation purposes during the last few decades. As a consequence, it has been contaminated with heavy metals including Mercury, which is highly toxic for human health. The permissible limit for Mercury in groundwater is 0.001 mg/L (1ppb). Mercury concentration in groundwater has been estimated using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) which is calibrated using a standard protocol. Ferozepur district in Punjab …

Precipitation Trend Analysis by MK Test in Garhwal Region Districts of Uttarakhand (1901–2010)
Abstract: Climate change has disrupted the major climatic parameters at a global level. However, the changes having localized intensity are not equal for all regions especially in India. These changes must be quantified locally to manage the natural water resources more effectively. Precipitation is one of the most important climatic parameters. It has been widely measured as a starting point towards the apprehension of global climate change. The purpose of this …

Green Fabrication of Glutaraldehyde-Crosslinked Chitosan/PVA Biocomposite for Heavy Metal Removal from Wastewater
Abstract: Chitosan (CS) and Polyvinyl alcohol (PVA) are polymers that possess biodegradable, biocompatible, and non-toxic properties, making them suitable for wastewater treatment applications. The primary objective of this research is to chemically modify chitosan in a novel manner to enhance its ability to remove hexavalent chromium Cr(VI) from aqueous solutions. In this study, a composite material was synthesized by crosslinking PVA and CS with glutaraldehyde (GA), resulting in the formation of …
