Impacts of dredged material disposal on estuarine benthic macrofaunal communities in Coos Bay, Oregon

Creator:: Erman, Lisa T.
Abstract:: Hopper dredge disposal of coarse grained sediment was investigated between May and September, 1986, at a designated disposal area, Site G, in Coos Bay, Oregon. The objectives of the study were to: (a) identify and describe the benthic macrofaunal community structure at Site G during May and September, 1986; (b)...

Small mammal micro- and macrohabitat selection in streamside ecosystems

Creator:: Doyle, Arlene T.
Abstract:: During summer and fall of 1981 to 1983, mark-recapture was conducted in riparian and upland habitats within old-growth and mature forests in the Cascade Range of Oregon. Number of individuals and species richness were greater in riparian than upland habitat. For most species, the mean adult weights and the percentages...

Atmospheric trace element abundances associated with slash burning

Creator:: Ungerer, Carl Andre
Abstract:: The atmospheric trace element abundances associated with slash burning have been measured by instrumental neutron activation analysis (INAA). On site ground level samples were collected during the slash burning season using high volume samplers and a cascade impactor. In addition to the air samples, soil, wood and ashed wood samples...

Identification and inheritance of factors influencing the rate and duration of grain fill in selected wheat populations, (Triticum aestivum L. em Thell)

Creator:: Chuhe, Chen
Abstract:: To study the grain filling traits in wheat, two winter cultivars and four spring cultivars were selected. The resulting Fl, F2, F3 and backcrosses were tested. The following measurements were made: a) Visual traits for physiological maturity (PM), b) Grain dry weight accumulation, c) Regression models for grain filling period,...

Table Beet Yield and Boron Deficiency as Influenced by Lime, Nitrogen, and Boron

Creator:: Hemphill, Delbert D. Jr, Weber, Michael S., and Jackson, T. L. (Thomas Lloyd), 1922-
Abstract:: Yield, occurrence of root canker (B deficiency), and leaf nutrient concentrations of the Morse strain of ‘Detroit Dark Red’ table beet (Beta vulgaris L.) as influenced by combinations of lime and N, B, and P fertilizers were evaluated in three studies. Greatest total yields and most favorable distribution of root...

Effects of growth retardant and nitrogen level on growth, development and yield of Yamhill wheat

Creator:: Nounamo, Laurent
Abstract:: Increases in wheat production due to breeding may be reaching a plateau. The application of N-fertilizer beyond optimum levels leads to lodging and to an increase in tiller death. The use of plant growth regulators (retardants) may be an answer for future increases in production. Experiments were conducted in 1983...

Unidirectional error correcting/detecting codes

Creator:: Lin, Der Jei
Abstract:: An extensive theory of symmetric error control coding has been developed in the last few decades. The recently developed VLSI circuits, ROM, and RAM memories have given an impetus to the extension of error control coding to include asymmetric and unidirectional types of error control. The maximal numbers of unidirectional...

Observability and information structure of nonlinear systems

Creator:: Hwang, Chun Sik
Abstract:: An observability problem for both deterministic and stochastic systems is studied here. Deterministic observability is a determination of whether every state of the system is connected to the observation mechanism and how it is connected, if connected. On the other hand, stochastic observability discusses the "tightness" of the connection in...

Influence of irrigation and plant population on yield parameters, flower and pod abscission, and photosynthate distribution in snap beans, Phaseolus vulgaris L.

Creator:: Mauk, Craighton Stiles
Abstract:: During 2 seasons effects of high and low irrigation (water applied at -0.6 and -2.5 bars soil water potential, respectively) and density were evaluated on yield parameters and flower/pod development at mainstem nodes 2 and 6 (terminal) of 'Oregon 1604', a determinate snap bean. High and low plant densities were...
