Honey-processed Astragalus is a dosage form of Radix Astragalus mixed with honey by a traditional Chinese medicine processing method which strengthens the tonic effect. Astragalus polysaccharide (APS), perform its immunomodulatory effects by relying on the tonic effect of Radix Astragalus, therefore, the improved pharmacological activity of honey-processed Astragalus polysaccharide (HAPS) might...
BACKGROUND Quantifying the benefits of reducing hazardous air pollutants (HAPs, or air toxics) has been limited by gaps in toxicological data, uncertainties in extrapolating results from high-dose animal experiments to estimate human effects at lower doses, limited ambient and personal exposure monitoring data, and insufficient economic research to support valuation of the health impacts often ...
Our previous research showed that poly(vinyl alcohol) (PVA) nanoparticles incorporating DNA with hydrogen bonds obtained by high hydrostatic pressurization are able to deliver DNA without any significant cytotoxicity. To enhance transfection efficiency of PVA/DNA nanoparticles, we describe a novel method to prepare PVA/DNA nanoparticles encapsulating nanoscaled hydroxyapatites (HAps) prepared b...
Augmenting ground-level communications with flying networks, such as the high-altitude platform system (HAPS), is among major innovative initiatives of next generation wireless systems (6G). Given HAPS quasi-static positioning at stratosphere, HAPS-to-ground and HAPS-to-air connectivity frameworks are expected to be prolific in terms data acquisition computing, especially given mild weather qua...
High altitude platform station (HAPS) is a wireless repeater in the air. It can play a dominant role in observations, remote sensing and communication. The structure and composition of formation of HAPS are studied in this paper. The performance of the wireless communication link are researched. The simulation results shows that the power of receiver is proportional to the received power and th...
Global navigation satellite systems (GNSSs) are essential in providing localization and services to most of the world due their superior coverage. However, high pathloss inevitable atmospheric effect, positioning performance any standalone GNSS is still poor urban areas. To enhance legacy GNSSs areas, a system, which utilizes altitude platform station (HAPS) 5G gNodeBs (gNBs), futuristic vertic...
Research The U.S. Clean Air Act designates hazardous air pollutants (HAPs) as those that " may reasonably be anticipated to be carcinogenic, mutagenic " (Clean Air Act Amendments 1990), and exhibit other adverse health effects. Effective reduction of exposures to HAPs requires determining the compounds, exposure pathways, and sources that contribute the most to human health risk. Many prior ris...
BACKGROUND While there is evidence that maternal exposure to benzene is associated with spina bifida in offspring, to our knowledge there have been no assessments to evaluate the role of multiple hazardous air pollutants (HAPs) simultaneously on the risk of this relatively common birth defect. In the current study, we evaluated the association between maternal exposure to HAPs identified by the...
The recently accentuated features of augmenting conventional wireless networks with high altitude platform systems (HAPS) have fueled a plethora applications, which promise to offer new services ground users, as well enhance the efficiency and pervasion existing applications. Cloud-enabled HAPS, aims create HAPS-based datacenters that cloud has particularly emerged promising key enabler provide...
he Clean Air Act (CAA) Amendments of 1990 are inT tended to reduce emissions of volatile organic compounds (VOCs) by 70 to 90%. They specifically designate 189 compounds as hazardous air pollutants (HAPs). The EPA estimates that the aerospace industry generates 208,000 tons per year of HAPs plus an additional 145,000 tons per year of VOCs. Maximum Achievable Control Technology (MACT) standards ...
