Air quality is a global challenge issue, and many regions of the world, such as India, are experiencing daunting challenges. An important aspect to identify then control emissions from major contributing sources. To advance this aspect, paper describes an air network that has been set up in National Capital Territory Delhi (NCT-Delhi) source categories real-time. The various components include innovative cloud-based dashboard compile data real-time series PM instruments (Beta Attenuation...
The use of facemasks is proven to mitigate the spread coronavirus and other biological agents that cause disease. Various forms facemasks, made using different materials, are being used extensively, it important determine their performance characteristics. size-dependent filtration efficiency breathing resistance household sterilization wrap fabrics, isolation media (American Society for Testing Materials (ASTM)- non-ASTM-rated), were measured in filter-holder- mannequin-in-chamber-based...
To determine the impact of various aerosol mitigation interventions and to establish duration persistence in a variety dental clinic configurations.
Infectious diseases physicians are leaders in assessing the health risks a variety of community settings. An understudied area with substantial controversy is safety dental aerosols. Previous studies have used vitro experimental designs and/or indirect measures to evaluate bacteria and viruses from surfaces. However, these findings may overestimate occupational The purpose this study was directly measure aerosol composition assess for healthcare personnel patients. We instruments capture...
The COVID-19 pandemic has precipitated widespread shortages of filtering facepiece respirators (FFRs) and the creation sharing proposed substitutes (novel designs, repurposed materials) with limited testing against regulatory standards. We aimed to categorically test efficacy fit potential N95 respirator using protocols that can be replicated in university laboratories.
Novel designs and materials for filtering face-piece respirators (FFRs) have been disseminated in response to shortages during the COVID-19 pandemic. Since filtration efficiency depends on particle diameter air face velocity, relevance of material or prototype fit data test conditions. We investigate whether characterizing a filter holder at range velocities enabled precise prediction performance novel sewn mask design. While larger particles (> 500 nm) are more relevant inhalation exposure...
Abstract Objectives To determine the impact of various aerosol mitigation interventions and establish duration persistence in a variety dental clinic configurations. Methods We performed measurement studies endodontic, orthodontic, periodontic, pediatric, general dentistry clinics. used an optical spectrometer wearable particulate matter sensors to measure real-time concentration from vantage point dentist during routine care configurations (e.g, open bay, single room, partitioned...
These days there have been rising cases in road accidents involving e-vehicles, street animals and pedestrians.This is mainly due to the fact that e-vehicles are not able produce sounds on their own as conventional vehicles do.So we taken this problem statement decided make a module can replicate sound vibrations.The aim build device be easily installed an e-vehicle has ability imitate both vibration of vehicle at different speeds.Hence resulting safer roads.A sampled speeds will using mic...
Palato-radicular grooves (PRGs) are developmental anomalies of maxillary incisors that a site for plaque accumulation and periodontal infection, contributing to localized periodontitis. Here case PRG was initially thought be root fracture or cemento-dentinal tear is presented, along with discussion the importance systematic approach diagnosis.
Abstract COVID-19 pandemic has caused a severe demand for facemasks, and this resulted in the use of those made from alternate media. As SARS-CoV-2 spreads primarily due to airborne droplets, it is critical verify filtration efficiency these media based facemasks. While several are being tested used, commercially available dust cleaners have shown reasonable efficiency. This may also be potential electrostatic charge on surface which enhances capture fine particles. In manuscript, we report...
