The bacteria colonizing geologic core sections (attached) were contrasted with those found suspended in the groundwater (unattached) by examining the microbiology of 16 depth-paired core and groundwater samples using a suite of culture-independent and culture-dependent analyses. One hundred twenty-two meters was continuously cored from a buried chalcopyrite ore hosted in...
Over the continental shelf at 15°S off Peru, sigma-t is a well-defined
function of temperature (Figure 1) and hence temperature alone may be used
to monitor the changes in stratification, to test the thermal wind equation,
and to monitor the hydrographic response to wind events. In this report we
present...
Green sea turtles, Chelonia mydas, have endangered and threatened populations globally, but several populations show signs of population recovery. In Hawaii, nesting female green turtles have increased 5.7% year⁻¹ since 1973, but wide fluctuations in census counts of nesting females make recovery diagnosis difficult. For effective management planning, it is...
With over 800 languages spoken on the continent of
Africa, inter-cultural communication has always been difficult.
In addition, many of the peoples of Africa have
experienced colonial oppression. Various powers have
sought to interfere with intra-cultural dialogues and the
free flow of information. Their effectiveness, however,
was limited because of...
Whole blood selenium levels were measured in 207 horses, representing 41 ranches and 11 regions throughout Oregon. Age, sex,
diet, and history of disease were recorded. Diet was divided into
three categories; local feed only, commercial feed, and Se supplemented feed. Region (p<.01), diet type (p<.01), and a region x...
In twentieth century America, women continue the age-old struggle for recognition
as whole, intelligent individuals, not just an "other," less hearty, less deserving
or less capable being than man. Sarah Grimke spoke of the inequalities over 150 years
ago during the abolitionist movement when she compiled her major arguments into...
Authentic assessment of visitor learning in museum settings is a challenging
endeavor. Evaluation literature includes very few studies that link adult visitors' behavior
to their learning. Multiple data collection methods in a naturalistic environment hold
great promise for increasing understanding of informal public education.
In 1997, Oregon State University's Hatfield...
Adult dusky Canada geese (Branta canadensis
occidentalis Baird) were banded with plastic neck bands and
observed on the winter range during 1985-92. Annual
survival rates of adult geese estimated from observation
data ranged from 76% to 85%. A model of Canada goose
population dynamics was developed to illustrate
relationships between...
Soil organic matter (SOM) is the terrestrial biosphere's largest pool of organic carbon (C) and is an integral part of C cycling globally. Soil organic matter composition typically can be traced directly back to the type of detrital inputs; however, the stabilization of SOM results as a combination of chemical...
The controversial condition of carbohydrate craving is believed by some
researchers to be a defect in the regulation of food intake by an individual.
This defect is believed to be responsible for the inability of some persons to
control their food intake and therefore their weight. Research was conducted
to...
The purpose of this research was to examine some of
the factors which may affect body composition of
postmenopausal women. The effect of estrogen, physical
activity, diet and lifestyle were examined in 9 women
receiving estrogen replacement therapy and 11 women not
using this drug. For 3 consecutive days, the...
The travel cost method of deriving demand and value of recreation
does not include fixed costs of recreational durable goods purchases
or allow for supply restrictions on the number of suitable
sites available. The omission of these two real-world situations
results in derivation of demand curves which are more inelastic...
Two-year old Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings from two seed lots of different predicted hardiness levels were grown in two separate nurseries. Seedlings were lifted every four weeks from early October 1991 through March 1992 and exposed to controlled freezing temperatures. Fluorescence emissions of the seedlings were measured prior...
Phosphorodiamidate morpholino oligomers (PMOs) are novel antisense drugs in the early stages
of development. These synthetic DNA mimics contain the same bases found in DNA and anneal
to RNA in a complementary fashion. PMOs have been designed that target genes responsible for
producing essential proteins in organisms such as Escherichia...
In 1992, amendments to the Fishing and Aquaculture Law required rural communities
to organize into syndicates or cooperatives and to create resource management plans.
Once the Chilean Fisheries Service (SERNAP) approves these plans, villages could manage designated subtidal and intertidal areas. In response to these amendments, two villages, Puerto Aldea...
One of the most commonly diagnosed illnesses in the elderly population is cancer. Despite research to explain the consistent increase in incidence rates with age, the mechanisms are largely unknown. In order to explore the patterns in age-specific cancer incidence through visualization, tables and graphs were generated via SEER*stat of...
