The influence of polyphosphates upon the emulsification of
enzymatic hydrolyzates of casein and lactalbumin and upon salt-soluble
meat proteins was determined by a model system in which
oil-in-water emulsions were formed.
Sodium acid pyrophosphate, sodium tripolyphosphate and
sodium hexametaphosphate were mixed together in a weight ratio
of 4:2:4, respectively, to...

This report includes information concerning experimental use of unregistered pesticides or unregistered uses of pesticides. Experimental results should not be interpreted as recommendations for use. Use of unregistered materials or use of any registered pesticides inconsistent with its label is against both Federal Law and State Law.
A computationally efficient algorithm has been developed for
determining exact or approximate solutions for large scale generalized
fixed charge problems. This algorithm is based on a relaxation
of the Benders decomposition procedure, combined with a linear
mixed integer programming (MIP) algorithm specifically designed to
solve the problem associated with Benders...
This report summarizes the 1979 ocean salmon fishing season off the Oregon coast. Troll fishery landings were obtained directly from commercial fish receiving tickets supplemented with a survey of fish buyers to obtain the most up-to-date estimate of total landings. Recreational catch and effort were obtained from creel census survey...
Studies were initiated to determine the response of two common
groundsel biotypes (Senecio vulgaris L. ) to several s-triazine herbicides.
Herbicides tested were: 2-chloro-4,6-bis(ethylamino)-striazine
(simazine), 2-chloro-4-(ethylamino)-6-(isopropylamino)-
s-triazine (atrazine) 2-(sec-butylamino)-4-(ethylamino)-6-methoxys-
triazine (GS-14254), 2, 4-bis(isopropylamino)-6-methoxy-striazine
(prometone), 2-(tert-butylamino)-4-(ethylamino)-6-methylthio-
s-triazine (terbutryn), and 2, 4-bis(isopropylamino)-6-
methylthio-s-triazine (prometryne). One biotype was much more
susceptible than the...
Studies were conducted to determine the post-mortem stability
of lysosomes in the white muscle of rainbow trout (Salmo gairdneri)
and to determine whether lysosomal stability was related to rigor
mortis and its subsequent dissolution. In addition, isolated lysosomes
were subjected to different environments in an attempt to detect some
of...
Two light sensitive mutants of the green alga Scenedesmus obliquus strain D₃ have been characterized. The photodynamic nature of their sensitivity has been established, the subchloroplast site of photodamage has been investigated, and their noncarotenogenic character has been verified. The two mutants possess several similarities, although mutant L. S. -41...
This paper presents an application of the wave equation to the
problem of selecting a driving hammer for prestressed concrete piles.
The potentially damaging effects of these types of hammers on various
prestressed concrete piles were analyzed by means of parametric
studies carried out on a hypothetical group of problems...
The work reported herein was performed under the annual allotment from the Office of Water Resources Research to the Oregon Water Resources Research Institute. Funds were available over a three year period, but due to difficulty in acquiring graduate students, the total time spent on the project was only 21...
A cost reduction analysis is performed by coordinating
the exchange of LANDSAT (formerly ERTS) data between a CDC
3300 and a PDP8/L minicomputer. The LANDSAT data is displayed
on a 4002 Tektronix terminal by means of a grayscale output.
Large amounts of data and number manipulation are processed
in the...
Preliminary studies were run to determine the sensitivity and
reliability of enzyme-linked immunosorbent assay (ELISA) for the
detection of potato virus X (PVX). ELISA was found to be capable of
detecting PVX in tobacco at a 1:3333 sample dilution. The reliability
of ELISA for the detection of PVX in potato...
Studies of anisotropic and isotropic Raman line shape yield information about the rotational motion (rotational correlation function) and non-reorientational (vibrational) lifetimes. The rotational motion of carbon disulfide has been studied previously by the techniques of Raman spectroscopy (6, 43), Rayleigh scattering (43, 46) and direct measurement (47). This work was...
The ex-vessel coho salmon market has been paid scant attention
in the study of the salmon resources. This study is an attempt to
advance an understanding of the variations of ex-vessel prices and
landings during the coho season as well as between the various coastal
ports where the fish is...
The application of the least squares adjustment techniques to the
area of surveying has been considered and two computer programs
called HCONTRL and VCONTRL are developed for horizontal and vertical
control respectively. The principle of least squares is discussed
in chapter II. The observation and condition equations are compared
and...
In order to determine the source of bacteria in Tillamook Bay,
Oregon, water samples were collected monthly for six months during
the rainy season from October 1975 through March 1976 from the bay
and its tributaries, the Kilchis, Trask, Tillamook, and Wilson
Rivers.
Fecal coliform levels of these samples were...

Stem mapping of all trees greater than 15 cm dbh has
been completed on the 10.24 hectare watershed (No. 10) at H. J.
Andrews intensive study site. Using a 25 m grid system, mapping
of vegetation into 7 plant communities and then into 4 habitat
types has also been completed....
A high volume sampling system, employing Nuclepore filters and
designed for sampling particulate in the plumes from industrial
sources using a light aircraft, is described. The effluent of kraft
paper mills was sampled using this system and then analyzed by
electron microscopy.
Size distributions of particles were obtained at several...
The 1970 report considers catch/effort, statuses of major fisheries, and cumulative fish tagging data. Other topics included a groundfish bibliography, international fishery problems, and the sablefish fishery. The report includes a synopsis of otter trawl regulations and their rationale as of July 1, 1970.
Independent fission product yields are primary input nuclear
data in the evaluation of nuclear reactor after-heat when using a
nuclide-decay summation method. The error in yield values is one
of the major causes of uncertainty of this calculation. Since only
a small fraction of the fission product yields has been...
The use of terbacil for weed control was adapted by a high percentage
of Oregon peppermint growers soon after its introduction in
1967. To help clarify some of the implications of terbacil usage,
three studies were undertaken to collect information concerning (a)
the movement and build-up of terbacil in various...
Two strategic approaches to water quality control in Oregon's
Willamette River are presently being utilized: point source treatment
and flow augmentation. Dry weather releases from reservoirs are for
authorized purposes other than water quality. Reservoirs can participate
in pollution control by summer flow augmentation where authorized water
resource objectives (flood...
This report presents progress accomplished during the 20-month period from 1 July 1972 through 31 March 1974 as part of the program "Ecological Studies of Radioactivity in the Columbia River Estuary and Adjacent Pacific Ocean". This program is a continuing study supported by the Division of Biomedical and Environmental Research...
Scaling characteristics of calcium carbonate on a
heated surface in cooling tower water was investigated.
Bulk temperature was maintained constant at 95°F. Flow
velocities and surface temperatures ranged from 3 ft/sec to
10.3 ft/sec and from 105°F to 170°F respectively. City
water was used as make-up for two different water...
Experiments were carried out to study the movement of water and
halide anions in perched water tables or saturated zones in the soil
and upper rock mantle of eight different experimental sites located
on low hills near the western border of the Willamette Valley. At each
site the experimental procedure...
