Acute and chronic toxicity studies with monochlorobenzene in rainbow trout

Creator:: Dalich, George M.
Abstract:: The toxicity of chlorobenzene (CB) was investigated in rainbow trout following acute ip administration (1. 0 ml/kg, 1:1 in corn oil) and chronic exposure (2. 1 ppm and 2. 9 ppm) via the water in a continuously flowing system for 15 and 30 days. In the acute study, overt toxicity...

Determination of α-Amylase activity and soluble starch content in normal and cork spotted D̀'Anjou' pear fruit

Creator:: Li, Shiao Jing
Abstract:: There was a linear relationship of [alpha]-amylase activity from 2 to 12 hours incubation in both freeze-dried and fresh 'd'Anjou' pear fruit tissue. Activity was greater, however, in fresh as compared with freeze-dried tissues. [alpha]-Amylase activity from both types of samples was not detected until 60 minutes incubation. After 90...

Effects of harvest date on sweet corn maturity, sugar content and yield

Creator:: Wong, Yueh-Mei
Abstract:: Studies were conducted in 1976 and 1977 on the effects of harvest dates on maturity, yields and sugar content of four cultivars of sweet corn. The cultivars were 'Golden Cross Bantam', 'Jubilee', 'Rapidpak' and 'Tendertreat'. Moisture content of kernels ranged from 80 to 67 per cent for the six harvest...

Effects of stand density on site index in thinned stands of Douglas-fir in the Pacific Northwest

Creator:: Zumrawi, Abdel Azim M. A.
Abstract:: In site index studies, the hypothesis that height growth of most conifers is independent of stand density is commonly accepted. However, some studies have shown height growth to be influenced by density particularly on medium to poor sites. In this study two locations representing a high quality site (Hoskins area,...

Experimental and mathematical procedures for the estimation of shelf-life : application to temperature-abused chilled seafood

Creator:: Almonacid-Merino, Sergio Felipe
Abstract:: The validation and potential use of mathematical models to estimate the shelf-life of refrigerated food exposed to temperature abuse and basing such estimations on microbial growth was analyzed. Combined heat transfer, microbial growth models, and non-parametric statistical procedures formed a computer-based predictive tool to assess shelf-life and estimate the accuracy...

Forest ant composition, relative abundances, and foraging following aerial spraying of carbaryl to suppress Western Spruce budworm

Creator:: Murphy, Christopher F.
Abstract:: An outbreak of western spruce budworm Choristoneura occidentalis in the Blue Mountains of eastern Oregon in 1983 was treated with helicopter applied carbaryl. Effects of the spraying on forest ants were determined from pre- and postspray samples taken from two carbaryl sprayed and two unsprayed plots. In each 0.75-ha plot,...

Genetic variability for kernel hardness in two soft winter wheat (Triticum aestivum L.) cultivators

Creator:: Albahouh, Muhammed S.
Abstract:: To remain competitive in the international marketplace, soft white wheat cultivars grown in the Pacific Northwest must have consistent and predictable flour properties including kernel texture. As a consequence, there is a need to develop wheat cultivars for specific end uses. Wheat cultivars with very soft kernels are used largely...

Growth growing-stock relationships in young Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco)

Creator:: Sales Luis, Jaime Fernando
Abstract:: In the thinning theory, the hypothesis that the stand growth is unaffected by the density over a broad range of densities is generally accepted today. In this study three different measures of stand density were used in basal area growth and volume growth multiple regressions in even-aged managed stands, searching...

Influence of planting density on spike size and grain yield in five winter wheat cultivars

Interactions between the immune system, stress and thymulin

Creator:: Christian, Richard L., (Richard Leroy), 1971-
Abstract:: This study was conducted to determine the effects of shipping stress on the immune system in domestic lambs (Ovis aries) and to determine the potential of the thymic peptide, thymulin, to reduce those effects of stress on the immune system. Treatments consisted of no shipping (as unstressed controls), shipping (as...

Land surface energy balance and surface soil moisture variation in HAPEX-MOBILHY

Creator:: Nichols, William E.
Abstract:: The HAPEX-MOBILHY regional experiment provided an significant opportunity to analyze the partition of energy and distribution of water over land surfaces. The combination of remotely sensed data and ground instrument networks over the large-scale in situ experiment allowed investigation of spatial and temporal variation of such hydrologic parameters as the...

Performance of Oregon derived malolactic bacteria : studies on storage stability and their use in the wine industry

Creator:: Micheals, Nancy J.
Abstract:: Commercial vats of Chardonnay and Pinot Noir were inoculated during yeast fermentation with starter cultures containing 10⁷ - 10⁹ cfu/ml of the malolactic bacteria Leuconostoc oenos Erla and Ey2d in lots ranging from 55 to 4,000 gallons. Chardonnay inoculated with Ey2d completed MLF in an average of 56 days at...

Pre-harvest sprouting tolerance of a synthetic hexaploid wheat (Triticum turgidum L. x Aegilops tauschii Coss.)

Creator:: Rosa, Andre Cunha
Abstract:: Pre-harvest sprouting in wheat costs farmers millions of dollars every year. Pre-harvest sprouting tolerance (PST) has minimized this problem, but improvement of PST is still necessary. Synthetic hexaploid wheats (synthetics) have been used as sources of genes coding for many useful traits. Two studies evaluated the PST of a synthetic...

Relationship between pore size, particle size, aggregate size and water characteristics

Creator:: Wu, Laosheng
Abstract:: Soil pore size distribution and water characteristics are important for water storage, water movement, and soil-plant interaction studies. Laboratory determinations of water characteristics and pore size distribution are time consuming and costly. Investigators have proposed many models to predict them from routinely available data. Most of the models are related...
