suppression of coke formation in thermal cracking by coke inhibitors
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
15 صفحه اولSuppression of Meloidogyne chitwoodi with Sudangrass Cultivars as Green Manure.
Meloidogyne chitwoodi race 1 reproduced on Piper sudangrass (Sorghum bicolor (L.) Moench), 332 (sudangrass hybrid), and P855F and P877F (sorghum-sudangrass hybrids), but failed to reproduce efficiently on Trudan 8, Trudex 9 (sudangrass hybrids), and Sordan 79, SS-222, and Bravo II (sorghum-sudangrass hybrids). Meloidogyne chitwoodi race 2 behaved similarly and reproduced more efficiently on Pip...
متن کاملWeed seed viability in composted beef cattle feedlot manure.
Manure composting has gained increased acceptance by the beef cattle (Bos taurus) feedlot industry in southern Alberta, Canada. Unlike fresh manure, compost is often promoted as being "weed-free." Studies were conducted with five weed species in 1997 and thirteen in 1999 to examine the effect of feedlot manure composting on weed seed viability. Weed seeds were buried in open-air compost windrow...
متن کاملWeed Suppression by Release of Isothiocyanates from Turnip-Rape Mulch
wick et al., 1983). Living plants do not actively release high amounts of ITCs (Börner, 1961), because glucosiThe allelopathic potential of isothiocyanates (ITC) released by nolates are located in the vacuole and myrosinase is turnip–rape mulch [Brassica rapa (Rapifera Group)–Brassica napus L.] was evaluated. Six different ITCs were identified from chopped bound to the cell wall (Björkman, 1976...
متن کاملSuppression of Root-knot Nematode Populations with Selected Rapeseed Cultivars as Green Manure.
Meloidogyne chitwoodi races 1 and 2 and M. hapla reproduced on 12 cultivars of Brassica napus and two cultivars of B. campestris. The mean reproductive factors (Rf), Rf = Pf at 55 days / 5,000, for the three nematodes were 8.3, 2.2, and 14.3, respectively. All three nematodes reproduced more efficiently (P < 0.05) on B. campestris than on B. napus. Amending M. chitwoodi-infested soil in plastic...
