In this work we propose a computer based approach by means of
which the decision maker in Bendel State, Nigeria, can best be assisted
in the formulation of policies related to land use.
In Chapter I we briefly discuss the role of the computer in
planning and state the problem....
The intent of "Oregon Port Districts: An Economic Profile" is to present
a profile of the activities of the Oregon Port Districts and to evaluate
some of the economic contributions that port district operations made in
1975. The study reflects the present role of the port districts within
their community...
A Resource Planning and Management System (RPMS) and Goal

The yields from the oxidation of 4-methylpyrimidine with potassium permanganate were found to increase from 25 to 92 percent by the addition of small amount of potassium hydroxide to the reaction mixture. Pyrimidine-4-carboxylic acid decarboxylates in hot aqueous solution to yield pyrimidine and carbon dioxide. The rate is that decarboxylation...
An attempt was made to create a hormonal environment of the
uterus comparable to that near the time of natural laying and to
eliminate the effect of a hard-shelled egg on fertilization. Hens without
hard-shelled eggs in their uteri were injected with the posterior
pituitary hormones, oxytocin and arginine vasopressin,...
Low concentrations of hexachlorophene (HCP) inhibit a number of pyridine nucleotide-linked dehydrogenase enzymes. The I₅₀ HCP concentrations were 105 μM for pig heart isocitrate dehydrogenase (ICD), 65 μM for horse liver alcohol dehydrogenase, 39 μM for torula yeast glucose-6-phosphate dehydrogenase (G6PD), 6.0 μM for beef heart malate dehydrogenase, and 1.6...
Blackside dace, Rhinichthys osculus nubilus (GIRARD), were
collected from ten western Oregon streams and examined for variation
among morphological and meristic characters. Several characters were
observed to vary between populations studied. Number of vertebrae,
number of scales in and above the lateral line, length of snout, and
depth of body...
Meiotic chromosome counts from 200 populations of Claytonia
(Montia) perfoliata (sensu lato) reveal a polyploid pillar complex based
on three morphologically different, chemically distinct, and geographically
defined diploids. The basic chromosome number is x=6.
Diploid C. perfoliata Willdenow with linear juvenile leaves and deltoid
mature basal leaves ranges southeastward from...
Stepwise multiple regression techniques were used to statistically analyze the relationships between damage caused by the pine needle sheath miner Zellaria haimbachi (Busck); a needle miner, Oenerostoma etrobivorum (Zeller); sugar pine tortrix, Choriatoneura Zambertiana (Busck); and ambient and foliar concentrations of fluoride in lodgepole pine (Pinue contorta v. Zatifolia Engelm.)...
Copper deficiency and Mo-induced Cu deficiency are nutrition
problems of ruminant livestock in the Burns and Klamath Falls area
of Oregon. Chemical analysis of plant and soil samples was used to
survey Cu and Mo levels in forage in these areas. The objectives
were to assess the possibility of animal...
Variation in growth rate of Dover sole (Microstomous pacificus) off Astoria and Brookings, and English sole (Parophrys vetulus) growth off Astoria and Coos Bay, Oregon was studied using the distance between annuli on scales and interoperculum bones indicating growth rate for Dover sole
and English sole respectively. The age at...
This study examines a limited number of selected themes in
Judeo-Christian, or Western, religious thought and their implications
for man's use of land, with the objective of discovering the influence
of Western religion on attitudes toward nature and land.
Five themes are examined: dominion of man; stewardship; contempt
for, and...
This method of character recognition is according to the topological
features of a.given character. First store the image of a
Chinese character into the storage of the computer. Each image of
the character appears as a 20 x 20 binary matrix. Each small square
in the matrix is designated as...
The length of time that atmospheric pollutants released from low-level
sources in the midwestern United States can expect to remain in
the atmosphere is discussed. The pollution is assumed to be removed
from the atmosphere by dry deposition and precipitation scavenging.
Layer-average trajectories originating from Kansas City, Missouri are
used...
A free-air gravity anomaly map of the continental margin of
Peru between 12° and 18° S. Lat. shows a -110 to -220 mgl anomaly
associated with the Peru-Chile Trench, a -60 mgl anomaly over the
Pisco Basin on the continental shelf, and -120 mgl anomaly over the
Mollendo (or Arequipa)...
To investigate the movement of elements (N, P, k, Ca, and Mg) from the tree crowns by natural litterfall and leave wash, plots were established on six 450 year-old growth stands at the H. J. Andrews Experimental Forest. The following are the results of the data analyses. Elemental concentrations contained...
To observe the effects of oviposition as related to time of insemination
on fertility, four trials were conducted in which individually
caged White Leghorn hens were artificially inseminated with 0.05 cc
of undiluted mixed semen obtained from 4 to 5 cockerels. These inseminations
were made at 9:45 a.m. , 10:00...

in
.05 M NaAc, pH = 6.9-7.2, .15 M or p = .15 with NaCl) resulted

Maximal decrease (40%) occurred within six...
The proteolytic enzymes in the visceral organs of albacore tuna
fish (Thunnus alalunga) were studied, initially as an extract of the
whole viscera, then as extracts of the individual organs. Preliminary
studies indicated three pH optima of activity in the whole viscera
extracts pH 1.7, 3.1-3.5 and 9.5. Analysis of...
Forest managers are, and will continue to be, constantly confronted with the dilemma of choosing between different silvicultural and management systems to achieve various desired mixes of multiple-use benefits on specific forest properties. Such choices have to be made, unfortunately, because no single silvicultural or management system is ideal for...
A new method for the preparation of the 2, 3, 3a,8a-tetrahydro-2-hydroxyfuro[2, 3-b] benzofuran, XXX, ring system has been developed. The synthesis envolved a substitution reaction of phenol, XXIV, with 1-bromo-2, 5-hexadiene, XXV, to give 2, 5-hexadien-l -yl phenyl ether, XXVII. The ether was rearranged via an ortho-Claisen rearrangement to 3-(o-hydroxyphenyl)-l,...
This study was an experimental investigation of two methods of
teaching students the cognitive knowledge and psychomotor skills pertaining
to the automobile brake system. The methods investigated
were the experimental individualized learning system and the traditional
group-lecture and demonstration.
Experimental Design and Procedure
The experiment, conducted during the spring term...
Selected parameters that affect crude toxin production in both
primary culture (growing cell culture) and resting culture were
examined during efforts to produce sufficient crude toxin for purification.
The parameters included carbohydrate and label source and
concentration, cell concentration, incubation time and temperature
and shaker speed. A higher yield of...
Demersal fishes were sampled at seven stations located inshore of Heceta Bank, on Oregon's continental shelf, over a 2-yr period with a 3-m beam trawl designed to catch small fiatfishes. Two general assemblages of fishes were recognized: a shallow water 74-102 m), sandy-bottom association where Pacific sanddab, Citharichthys sordidus,was numerically...

This thesis describes a Mossbauer effect and electron
paramagnetic resonance study of iron (III) tetraphenylporphyrinatobenzenethiolate
benzene thiol, an analog compound
for bacterial cytochrome P-450. The compound is unusual in
that it provides a model for the two ferric reaction states
of cytochrome P-450. The iron in the model compound exhibits...
The cytoplasmic isozyme of malate dehydrogenase (s-MDH) has been isolated from brine shrimp nauplii to a state of high purity with a protocol involving ammonium sulfate fractionation and chromatography on DEAE-cellulose, followed by sequential passes over cellulose phosphate columns at pH 5.8 then 5.0. The purified enzyme is free of...
Lamellar x-ray diffraction was studied from thin films of L-α-1,2-dipalmitoyl lecithin (DPL) and a 1:1 mixture (BrDPL) of L-α-l-palmitoyl-2-(9- bromopaimitoyl) lecithin and its 10-bromo analog. The specimens had high lamellar order, with an upper bound on the mosaicity of 6 mrad (0.4°) for DPL and BrDPL. With various water contents,...
A study was made of the subgenus Genuini of the genus Juncus in the Pacific States, California, Oregon and Washington. Extensive morphological comparisons, geographical distributions, habitat differences and observations of apparent presence or absence of natural hybrids provided the major data sources. Cytological studies were made, but were inconclusive. Eleven...
