Projecting a hazardous air pollutant (HAP) emission inventory to future years can provide valuable information for air quality management activities such as prediction of program successes and helping to assess future priorities. We have projected the 1999 National Emission Inventory for HAPs to numerous future years up to 2020 using the following tools and data: the Emissions Modeling System f...

Hepatitis B virus (HBV) core protein assembles viral pre-genomic (pg) RNA and DNA polymerase into nucleocapsids for reverse transcriptional DNA replication to take place. Several chemotypes of small molecules, including heteroaryldihydropyrimidines (HAPs) and sulfamoylbenzamides (SBAs), have been discovered to allosterically modulate core protein structure and consequentially alter the kinetics...

In recent years, a growing interest has been witnessed in the usage of free space optics (FSO) link for satellite communication (SATCOM) scenarios, as it offers much higher data rates up to gigabits per second (Gbps) compared existing radio frequency (RF) link. However, FSO links are sensitive beam scintillation and pointing errors. this paper, we consider hybrid FSO/RF between ground station (...

Integrating terrestrial networks with burgeoning high-altitude platform stations (HAPSs) will be a disruptive challenge for beyond-5G systems provisioning large-scale three-dimensional connectivity. Here, we study the problem of forwarding packets between terminals and backhaul through multi-HAPS relaying. Considering limited wireless backhaul, which is practical constraint HAPS relaying, dual-...

En el proceso de secado mecánico del café se emplea un intercambiador calor para calentar aire sin contaminar grano con los gases generados durante la combustión. Sin embargo, si utiliza Gas Licuado Petróleo (GLP) como combustible reducir costos proceso, secadores instalan calor, asumiendo que combustión GLP es una limpia. No obstante, desconoce contaminan café. Teniendo en cuenta lo anterior, ...
