INTERPRETING MOBILE AND HANDHELD AIR SENSOR READINGS IN RELATION TO AIR QUALITY STANDARDS AND HEALTH EFFECT REFERENCE VALUES: TACKLING THE CHALLENGES

The US Environmental Protection Agency (EPA) and other federal agencies face a number of challenges in interpreting and reconciling short-duration (seconds to minutes) readings from mobile and handheld air sensors with the longer duration averages (hours to days) associated with the National Ambient Air Quality Standards (NAAQS) for the criteria po

Abstract The monitoring of leakage current (LC) and voltage characteristics in transmission line insulators is regarded as a good technique for anticipating the physical state of in-service insulators.In the current work, the temporal and frequency characteristics of LC and voltage under various situations were derived for assessing the health cond

The silicification mechanism in sponges is a biologically controlled process where the complex and amazing shape of spicules is the result of the hierarchical assembly of silicon particles to form a composite structure with organic compounds, mainly constituted by proteins.In this work, using an integrated approach of transcriptomic and proteomic a

Ovarian follicular granulosa cells surround and nurture oocytes, and produce sex steroid hormones.It is believed that during development the ovarian surface epithelial cells penetrate into the ovary and develop chicago bears wagon into granulosa cells when associating with oogonia to form follicles.Using bovine fetal ovaries (n = 80) we identified

Abstract Background Mast cell-derived prostaglandin D2 (PGD2), may contribute to eosinophilic inflammation and mucus production in allergic asthma.Chemoattractant receptor homologous molecule expressed on TH2 cells (CRTH2), a high affinity receptor for prostaglandin D2, mediates trafficking of TH2-cells, mast cells, and eosinophils to inflammatory
