Effect of hydrous ethanol on crankcase oil dilution

Creator:: Khalifa, Gamaleldin A.
Abstract:: Adequate lubrication is of the utmost importance in internal combustion engines. Low temperature operation with low-proof alcohol may create some operational problems if alcohol and or water accumulates in the crankcase oil. Condensates of unburned alcohol and water may be blown into the crankcase oil with blow by gases. The...

Mass transport in laboratory water wave flumes

Creator:: Kim, Tae In
Abstract:: A complete solution, exact to second-order, for wave motion forced by a hinged-wavemaker of variable-draft is presented. A solution for a piston type wavemaker is also obtained as a special case of a hinged-wavemaker with negative infinite draft. The existing Stokes inviscid theories for mass transport is extended to include...

Relevance of U. S. graduate education in agriculture to careers in agricultural development of East African agriculturalists

Creator:: Acker, David G.
Abstract:: The purpose of this study, to examine the relevance of U.S. graduate education in agriculture to careers in agricultural development of East African agriculturalists, was examined in terms of three problems: Problem 1: Was U.S. graduate education in agriculture relevant to careers in agricultural development of East African agriculturalists? Problem...

Sweet corn (Zea mays L.) production in a white clover (Trifolium repens L.) living mulch : the establishment year

Creator:: Cooper, Alan S.
Abstract:: Oregon sweet corn growers face high fertilizer, fuel and weed control costs; soil compaction, erosion, organic matter and nutrient depletion; and difficult equipment operations in muddy fields. An alternative production system might ease some of these problems. Testing was begun to evaluate a living-mulch cropping system for sweet corn (Zea...

A study of methods of parental evaluation using testers to predict subsequent progeny performance in winter wheat (Triticum aestivum L.)

Creator:: Alexander, William Larry
Abstract:: The major objective of this study was to determine why certain winter wheat cultivars, when hybridized, will produce a greater proportion of desirable plants in subsequent, segregating generations. Three winter wheat parents were chosen as the experimental material, based on their known performance as parents. Yamhill and Pullman Selection 101...

Turbulent structure in the bora and stable boundary layer

Creator:: Frank, Helmut P.
Abstract:: An eigenvector analysis of the velocity-temperature correlation matrix is applied to clear-air turbulence measured by aircraft in the Bora. The eigenvectors are identified with the main eddies of the turbulence. This study attempts to infer the three-dimensional structure of these eddies. The results are compared with turbulent structures in the...

Diffusion of oxygen and carbon dioxide through soil with temperature and water content effects on sink/source strength

Creator:: Ying, Ouyang
Abstract:: Gaseous diffusion equations which describe the diffusion of oxygen and carbon dioxide through soil have been studied by several investigators. However, these efforts seldom considered gaseous diffusion through soil together with the effects of soil environmental factors such as soil temperature and soil water content on sink or source strength....

Structure of turbulence in stratified flow : aircraft data from SESAME and ALPEX

Creator:: Gamage, Nimal K. K.
Abstract:: Several horizontal flight segments from SESAME and ALPEX are studied using structure functions and specral analysis methods. Theoretical analysis of the relative errors in structure function and correlation function in the presence of large scale wave activity is presented. The effect of stratification and shear on the -5/3 inertial subrange...

An examination of structure and parameterization of turbulence in the stably-stratified atmospheric boundary layer

Creator:: Ruscher, Paul Harold
Abstract:: The very stable boundary layer is a region of the atmosphere typified by large vertical gradients of temperature and momentum. Analysis of very stable atmospheric flows is complicated by the presence of nonlinear interactions among gravity waves, shear-driven overturning circulations, two-dimensional vortical modes and intermittent turbulence in various stages of...
