Alkylation studies on Hagemann's ester: an approach to the synthesis of the trisporic acids

Creator:: Sung, Wing Lam
Abstract:: Sequential alkylation of Hagemann's ester with methyl and methallyl halides has been studied. Treatment of Hagemann's ester with methyl iodide and sodium ethoxide gave a mixture of 21 and 25 in a ratio of 4:1. Alkylation of 21 with methallyl chloride and potassium t-butoxide afforded a mixture of 37 and...

Reduced Chemistry for a Gasoline Surrogate Valid at Engine-Relevant Conditions

Creator:: Niemeyer, Kyle E. and Sung, Chih-Jen
Abstract:: A detailed mechanism for the four-component RD387 gasoline surrogate developed by Lawrence Livermore National Laboratory has shown good agreement with experiments in engine-relevant conditions. However, with 1388 species and 5933 reversible reactions, this detailed mechanism is far too large to use in practical engine simulations. Therefore, reduction of the detailed...

The taxonomic value of the metathoracic wing in the Scutelleridae (Hemiptera: Heteroptera)

Creator:: Au, Eunice Chizuru
Abstract:: Classification based on metathoracic wing venation does not coincide with the existing higher classification of the family Scutelleridae. The wings of the genera in the Scutellerinae possess a similar general pattern of venation which is quite distinct from that of Eurygasterinae, Odontoscelinae, Odontotarsinae, and Pachycorinae. The Scutellerinae wings possess three...

Development of efficient and accurate skeletal mechanisms for hydrocarbon fuels and kerosene surrogate

Creator:: Zhong, Fengquan, Ma, Sugang, Zhang, Xinyu, Sung, Chih-Jen, and Niemeyer, Kyle E.
Abstract:: In this paper, the methodology of the directed relation graph with error propagation and sensitivity analysis (DRGEPSA), proposed by Niemeyer et al. [Combustion and Flame 157 2010) 1760–1770], and its differences to the original directed relation graph method are described. Using DRGEPSA, the detailed mechanism of ethylene containing 71 species...

Poleward propagating subinertial alongshore surface currents off the U.S. West Coast

Creator:: Kim, Sung Yong, Cornuelle, Bruce D., Terrill, Eric J., Jones, Burt, Washburn, Libe, Moline, Mark A., Paduan, Jeffrey D., Garfield, Newell, Largier, John L., Crawford, Greg, and Kosro, P. Michael
Abstract:: The network comprising 61 high-frequency radar systems along the U.S. West Coast (USWC) provides a unique, high resolution, and broad scale view of ocean surface circulation. Subinertial alongshore surface currents show poleward propagating signals with phase speeds of O(10) and O(100–300) km d⁻¹ that are consistent with historical in situ...

Identification of species and varieties of ryegrass (Lolium spp.)

Creator:: De Barros, Manoel Bernardo
Abstract:: The objective of this study was to investigate ryegrass seedling characteristics that, by themselves, or combined with presently known characters, could improve varietal identification tests. Thirteen characters were studied on 30 varieties of Lolium multiflorum Lam., L. perenne L., L. rigidum Gaud, and L. hybridum Hausskn., including leaf size and...

Conservation of arthropod natural enemies in broccoli with relay strip-cropping

Creator:: McGrath, Daniel M. (Daniel Morton)
Abstract:: Relay strip-cropping combines two vegetation management tactics, under-sowing and strip-management. In this study conducted from 1994 though 1997, a cover crop seed-mixture containing oats (Avena sativa L. var. "Monida"), common vetch (Vicia sativa L.), red clover (Trifolium pratense L.), annual ryegrass (Lolium multflorum Lam.), and buckwheat (Fagopyrum esculentum Moench) was...

Cereal stem moth, Ochsenheimeria vacculella Fischer von Röslerstamm (Lepidoptera : Ochsenheimeriidae) : field biology and larval development on selected grasses and cereals in Western Oregon

Creator:: Panasahatham, Sarote
Abstract:: The seasonal life history of the cereal stem moth (CSM), Ochsenheimeria vacculella Fischer von Roslerstamm, (Lepidoptera : Ochsenheimeriidae) was investigated in a commercial field of annual ryegrass in the Willamette Valley, OR from January 1993 to August 1994.

The biology and behavior of the alkali bee Nomia melanderi Cockerell (Hymnoptera: Apoidea)

Creator:: Hackwell, Glenn Alfred
Abstract:: Nomia melanderi Cockerell is one of the most efficient pollinators of alfalfa in Eastern Oregon. Emergence begins in June, usually reaches its peak in early July, and may continue into early August. Male emergence precedes female emergence by four or five days. For the first few weeks of this time,...
