Bionomics of the hop cyst nematode, Heterodera humuli Filipjev, 1934 (Nematoda : Heteroderidae)

Creator:: Sen, Arun Kumar
Abstract:: The hop cyst nematode, Heterodera humuli Filipjev, 1934 was first reported from Europe in 1894, however, very little is known with respect to the biology and economic importance of this pest. Abundant material from Oregon hop yards provided an excellent opportunity to add additional details concerning the bionomics of this...

Acari, insecta and nematoda of watershed 10, H. J. Andrews experimental forest

Creator:: Krantz, G. W., Wernz, J. G., Jensen, Harold J. (Harold James), 1921-, Shimabukaro, R., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Populations of mites and.nematodes were monitored on Watershed 10, H. J. Andrews Forest. A minimum of 50 families and 60 genera of mites are present, the majority being Cryptostgmata. Population estimates vary from 5000-350,000 per square meter. Nine categories of nematodes are present, most belonging to the saprozoic, dorylaimoid, aquatic...

Alum coagulation in conjunction with the activated sludge treatment of corn processing waste water

Creator:: Jensen, Harold LeRoy, III
Abstract:: The treatment of waste water from a corn freezing process by activated sludge with the aid of alum coagulation was investigated. Both high and low energy level systems were observed with good flocculation occurring at the low energy level. Because poor flocculation occurs at high energy level conditions, alum was...

Investigations into the physiology of nitrogen fixation : Part I. Nickel metabolism of plants and bacteria : Part II. Peroxide scavenging in soybean root nodules

Creator:: Dalton, David Andrews
Abstract:: PART I. The concentration of nickel in some soils may be insufficient to meet the requirements of enzymes such as urease in soybeans and hydrogenase in Rhizobium. Nickel availability in soils was examined by measuring microbial urease activity in soils which were treated with glucose and urea. Supplemental nickel was...

A numerical study of mesoscale motion in the atmospheric mixed layer

Creator:: Ruscher, Paul Harold
Abstract:: The numerical modeling of motions in the atmosphere's planetary boundary layer (PBL) is a challenging task. In general, the boundary layer interacts with both the overlying atmosphere and the underlying land or water surface in a complex manner. Random turbulence is also present in the PBL which precludes exact prediction...
