Asthma is a respiratory disease whose prevalence has been increasing since the mid 1970s and that affects more than 14.6 million residents of the United States. Environmental triggers of asthma include air pollutants that are respiratory irritants. Air toxics emitted into the ambient air are listed in the 1990 Clean Air Act Amendments as hazardous air pollutants (HAPs) if they can adversely aff...
The hazardous air pollutants (HAPs) group is composed of 187 chemicals that are known to be potentially carcinogenic and dangerous for human health. Due their toxicological impact, HAPs an increasingly studied class compounds. Of the different sources, refineries one major sources. In order obtain a preliminary assessment impact refinery in terms emissions, useful instrument determination emiss...
BACKGROUND Hypoxic niches in solid tumors harbor therapy-resistant cells. Hypoxia-activated prodrugs (HAPs) have been designed to overcome this resistance and, to date, have begun to show clinical efficacy. However, clinical HAPs activity could be improved. In this study, we sought to identify non-pharmacological methods to acutely exacerbate tumor hypoxia to increase TH-302 activity in pancrea...
A downlink performance of deploying WiMAX (IEEE802.16a) both from High Altitude Platforms (HAPs) and from terrestrial base stations sharing the 3.5GHz band is presented. It is shown how these two wireless communication configurations can coexist with either adjacent or overlaying coverage areas. The performance of each deployment is affected by factors such as transmission power, antenna beamwi...
An integrated satellite-HAPS system is particularly suitable for supporting emergency communications. A key element for the efficient adoption of such systems is the enhancement of transport layer capability to support TCP-based applications. This paper proposes a detailed analysis of TCP performance over the target scenario, involving a DVB-RCS protocol stack for satellite air interface. I-PEP...
Non-terrestrial networks, including Unmanned Aerial Vehicles (UAVs), High Altitude Platform Station (HAPS) nodes and Low Earth Orbiting (LEO) satellites, are expected to have a pivotal role in sixth-generation wireless networks. With inherent features such as flexible placement, wide footprints, preferred channel conditions, they can tackle several challenges faced by current terrestrial Howeve...
