Cardiac output and respiratory measurements in the rainbow trout and their application to the study of blood and water flow limitations on chemical flux at the gill

Creator:: Schmieder, Patricia K. (Patricia Kathleen)
Abstract:: A method has been developed for the continuous automated monitoring of cardiac output in adult rainbow trout. Average cardiac output measured under control conditions and varied environmental conditions of hypoxia and post-hypoxia was significantly higher (P≤ 0.05) in male than female trout. The cardiac output of trout in spawning condition...

Application of GNSS for Vertical Reference Determination

Creator:: Kim, Su-Kyung
Abstract:: Vertical datum is a reference system used for specifying the elevation of specific points on or near the Earth. Precise and accurate definition and realization of vertical references are, therefore, crucial to ensure consistency between height measurements. The vertical datums can be divided into two categories: 1) vertical geodetic datums...

Strengthening school readiness for children at risk : evaluating self-regulation measures and an intervention using classroom games

Creator:: Schmitt, Sara A.
Abstract:: In recent years, self-regulation has emerged as a foundational skill for academic success and well-being. Unfortunately, many children enter kindergarten without the self-regulation skills necessary to succeed. Children from high-risk backgrounds (e.g., low-income) are particularly vulnerable for difficulties in self-regulation development. Given these documented gaps in self-regulation, it has become...

Root initiation and elongation in Douglas-fir, Pseudotsuga menziesii (Mirb.) franco, stem cuttings as related to bud and cambial activity

Creator:: Bhella, Harbans Singh
Abstract:: The relation of bud and cambial activity to root initiation and elongation in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stem cuttings was studied through two successive growth cycles. Stem cuttings of current season's growth were taken periodically from field-grown Douglas-fir trees to determine: (1) origin and development of root initials; and...

The accuracy, applicability and transferability of contingent valuation measures for nonmarket goods

Creator:: Berrens, Robert Patrick, 1962-
Abstract:: Despite several decades of research developments, the survey-based contingent valuation (CV) method remains one of the most controversial topics in environmental economics. As the procedure matures and more applied studies are completed, there is increasing pressure to make the results policy relevant. This research is composed of three distinct yet...

The Tabanidae (Diptera) of Oregon

Creator:: Mahmoud, Ali Ahmed
Abstract:: Fifty species and subspecies and six varieties in eight genera of the family Tabanidae are recognized from Oregon. The following genera are represented in Oregon: Apatolestes Williston, Pilimas Brennan, Stonemyia Brennan, Silvius Meigen, Chrysops Meigen, Atylotus Osten Sacken, Hybomitra Enderlein and Tabanus Linnaeus. Adults and larvae were collected from various...

Directing ecological succession : the role of competition in restoring semi-arid grasslands dominated by invasive plants

Creator:: Mangla, Seema
Abstract:: Successful ecosystem restoration requires an understanding of the ecological processes directing succession. One of the challenges in the semi-arid grasslands of western United States is replacement of native species by invasive annual grasses. Solutions to this problem require identifying and manipulating ecological processes that direct succession to favor desired vegetation....

An assessment of the cardiac toxicity of compounds that cause methemoglobinemia using a non-vascularized fish heart model

Creator:: Nichols, John W.
Abstract:: Non-vascularized hearts of buffalo sculpin (Enophrys bison) were used to investigate the cardiac toxicity of compounds that cause methemoglobinemia. The affinity of sculpin cardiac myoglobin for oxygen (P50 = 1.10 torr at 20 C°, pH 7.8) was lower than that of mammals studied (P50 = .44 and .76 torr for...

A taxonomic revision of Astragalus mokiacensis and allied taxa within the Astragalus lentiginosus complex of Section Diphysi

Creator:: Alexander, J. Andrew
Abstract:: North America, with over 400 species of Astragalus (Fabaceae), is one of three major centers of diversity, all of which comprise the majority of the nearly 1750 species of Astragalus worldwide. One of the most diverse species, Astragalus lentiginosus of Section Diphysi, is a polymorphic complex of over 40 varieties,...
