The impact of airflow on volatile organic compound (VOC) emissions from “wet” materials has long been noticed. However, a comprehensive mass transfer model that can predict such an impact has not been reported. The objective of this research was to fill that gap. First, we measured the VOC emissions of “wet” coating materials (a decane and a wood stain)(More)

Among nonhuman primates, SIV-infected Asian pigtailed macaques (PM) are relatively more susceptible to infection and disease progression than SIV-infected rhesus macaques (RM). In addition, SIV-infected African natural hosts such as the sooty mangabeys (SM) are resistant to disease. The mechanisms associated with such species-related variable clinical(More)
Substantial concentrations of trace gases and aerosols are lofted and carried from Asia over the Pacific producing an inter-hemispheric impact on atmospheric chemistry and climate. The meteorological mechanism leading to this large-scale transport of dust and pollutants remains a major uncertainty in quantifying the global effects of emissions from the(More)

Arsenism is a disease with severe damage to human health resulting from long-term exposure to high arsenic levels in the environment. Selenium was used to prevent the accumulation of arsenic in the human body and rectify the damages in the experiment. After the administration of 100–200 μg Se/day for 14 months, 75.0 and 55.0% of the patients served as(More)
Photonics involves the control of photons in free space or in matter. Manipulation of photons in semiconductor bulk crystals and thin films has culminated in breakthroughs such as LEDs and lasers. The continuing success of photonic technologies relies on the discovery of new optical materials and the miniaturization of optoelectronic devices that feature(More)

This paper proposes a new approach for cluster based routing algorithm for hybrid mobility model to regulating the vehicular traffic. Our approach uses a new hybrid mobility model combining randomwaypoint and group mobility model using static and dynamic sources and a novel cluster based routing algorithm. To transmit the real time updated information and(More)
