HC-SCR of NO\(_x\) emissions over Ag-AL\(_2\)O\(_3\) catalysts using diesel fuel as a reductant
Hydrocarbon selective catalytic reduction (HC-SCR) of nitrogen oxides (NO\(_x\)) over silver-alumina (Ag-Al\(_2\)O\(_3\)) catalysts, in diesel exhaust gas, has been investigated and presented in this research thesis. The work involved the use of H\(_2\) to activate diesel-type HC reductants. …

Soybean Mosaic Virus Hc-Pro Enhances Viral Symptoms, Bean Pod Mottle Virus and Transgene RNA Stability, siRNA Accumulation, and Reduces Soybean Seed Production
… plants expressing SMV helper component protease (HC-Pro) at high levels had severe symptoms and enhanced accumulation of BPMV RNA and siRNAs. Transgenic lines expressing high levels of SMV HC-Pro mRNA had altered unifoliate leaf morphologies and reduced seed production. When inoculated with three …
