Impact of Hexavalent Chromium on Histopathology in Freshwater Stinging Catfish Heteropneustes Fossilis
Abstract: Acute toxicity of Cr (VI) (as K2Cr2O7) to freshwater stinging catfish, Heteropneustes fossilis and its histopathological impacts on gill and liver tissue were evaluated. Fish showed behavioral alterations after K2Cr2O7 exposure and 96 h-LC50 was 35.724 mg/L in static bioassay. Fish were exposed to three sub-lethal concentrations (concentration I=1/4th of 96 h-LC50, concentration II=1/10th of 96 h-LC50 and concentration III=environmental concentration of Cr reported in the river Buriganga). Blood, liver …

Bird-Tree Associations and Co-occurrence Patterns in Delhi: Implications for Urban Ecological Restoration and Invasive Species Management
Abstract: Urban trees and birds are intertwined indicators of ecological resilience in cities. This study maps citywide bird-tree interactions in Delhi, India, hosting more than 300 avian species. The city was divided into hexagonal grids, and bird–tree data (506 interactions) were collected through field surveys across 131 sites using standardized 1-kilometre transects. Native keystone species, like ficus, supported the greatest bird diversity, while invasive Prosopis juliflora was widely used for perching …

Smart Drainage Cleaning System: A Technological Intervention for Occupational Health and Urban Sanitation
Abstract: Manual drainage maintenance in urban environments remains a hazardous task, exposing sanitation workers to toxic gases, infections, and life-threatening accidents. This paper presents the development of an automated 12V Smart Drainage Cleaning System designed to eliminate manual scavenging and enhance cleaning efficiency. The robotic model operates on a 12V DC power supply, integrating an ultrasonic sensor for real time obstacle detection and automated navigation within narrow drainage pathways. The core …

IS-Aligned Strategic Evaluation of Fire Protection Systems for Improving Fire Safety in Mixed-Occupancy High-Rise Buildings
Abstract: This paper presents a substantially reworked Indian-context evaluation of fire protection systems in a 14-building high-rise sample from Indore. The study reuses the original field dataset but replaces the earlier code mix with an explicitly IS-aligned and NBC-oriented analytical framework. Physical observation, document review and interview inputs were screened against requirements related to means of egress, compartmentation, fire detection and alarm, hydrants and hose reels, extinguishers, emergency lighting, smoke control, …
