Militaq (i.e., DSCS) and Commercial (i.e., CSCI) Satellite Communications plays a significant role in providing bandwidth and connectivity for the Defense Information Systems Network (DISN), which is part of the larger Defense Information Infrastructure (DII). However, in the past, this bandwidth and connectivity has generally been provisioned as dedicated, full period trunks providing OSI Refe...

The Defense Satellite Communications System (DSCS) Operations Control System (DOCS) supports Department of Defense (DoD) communication users of Super High Frequency (SHF) satellites. The DOCS, a mature system, consists of stovepiped subsystems with minimal electronic interoperability. The Objective DSCS Operations Center (ODOC) program has been established to upgrade the DOCS using state-of-the...

The dependence of vegetation attenuation on propagation geometry has been experimentally investigated at SHF band for isolated single trees. Two measurement heights (Trunk and Canopy) have been used in these experiments that involve three fully foliated trees, Common Whitebeam (Sorbus aria), Silver Maple (Acer Saccharinum) and Common Hazel (Corylus Avellana). Result shows that apart from freque...

This study determined the optimal conditions for deep eutectic solvent (DES) pretreatment of sugarcane leaves and best fermentation mode hydrogen methane production from DES-pretreated leaves. Choline chloride (ChCl):monoethanolamine (MEA) is most effective removing lignin The optimum were a ChCl: MEA molar ratio 1:6, 120 °C, 3 h, substrate-to-DES solution 1:12. Under these conditions, 86.37 ± ...

This study evaluated batch fermentation modes, namely, separate hydrolysis and fermentation (SHF), Quasi-simultaneous saccharification and fermentation (Q-SSF), and simultaneous saccharification and fermentation (SSF), and fermentation conditions, i.e., enzyme and yeast loadings, nutrient supplementation and sterilization, on high titer bioethanol production from SPORL-pretreated Douglas-fir fo...

Smyd1/Bop is an evolutionary conserved histone methyltransferase previously shown by conventional knockout to be critical for embryonic heart development. To further explore the mechanism(s) in a cell autonomous context, we conditionally ablated Smyd1 in the first and second heart fields of mice using a knock-in (KI) Nkx2.5-cre driver. Robust deletion of floxed-Smyd1 in cardiomyocytes and the o...

An experimental study was carried out to investigate the effects of inlet pressure, sample thickness, initial sample temperature, and temperature sensor location on the surface heat flux, surface temperature, and surface ultrafast cooling rate using stainless steel samples of diameter 27 mm and thickness (mm) 8.5, 13, 17.5, and 22, respectively. Inlet pressure was varied from 0.2 MPa to 1.8 MPa...
