Analysis And Evaluation Of The Workplace Exposure Assessment Workbook Developed By Keith Tait Including Some Recommended Revisions, Lisa Hebberd Oct 1993

Analysis And Evaluation Of The Workplace Exposure Assessment Workbook Developed By Keith Tait Including Some Recommended Revisions, Lisa Hebberd

UNLV Theses, Dissertations, Professional Papers, and Capstones

Some risk due to the contamination of workplace environments is an inevitable part of human lives. These risks can often be reduced by improving the control of environmental pollution in the workplace. An extremely important challenge for any industry is to develop a mechanism to identify acceptable levels of safety, or "acceptable risk" in the workplace for specific situations, and to assure adequate quality control over measured or calculated exposure concentrations and their possible contributions to adverse health effects.

The Kuril Islands Dispute: An Obstacle In Russo-Japanese Relations, Roderick J. Fraser Jr. Jan 1993

The Kuril Islands Dispute: An Obstacle In Russo-Japanese Relations, Roderick J. Fraser Jr.

Theses and Major Papers

The controversy between Japan and Russia over the ownership of the Kuril Islands is a significant barrier to improved diplomatic relations in the Far Eastern region. Because of this dispute, Japan and Russia have not yet signed a peace treaty to formally end the second world war and neither side seems willing to make any significant concessions to reach a compromise. The issue of ownership of these islands has been a continuing focal point of Russo-Japanese relations since the two nations first made contact in the late eighteenth century. The various aspects of this dispute are complex and have continued …


The Structure Of The Holocephalan Head And The Relationships Of The Chondrichthyes, Eileen D. Grogan Jan 1993

The Structure Of The Holocephalan Head And The Relationships Of The Chondrichthyes, Eileen D. Grogan

Dissertations, Theses, and Masters Projects

The interrelationship of the chondrichthyan subclasses is evaluated based on divergence in the nature of the suspensorium, the preorbital cranial anatomy, the distribution of major venous sinuses and localization of hematopoietic tissue. The anatomy of representative extant taxa was examined by radiography and/or dissection. Fossil selachians, paraselachians, and holocephalans of the Bear Gulch of Montana, U.S.A. (Mississippian, Namurian E2B) were studied for evidence of vascular pigmentation, suspensorium, and cranial, branchial, and pectoral anatomy. These studies validate the suspensorial condition of autodiastyly and suggest autodiastyly is a fundamental condition involved in the basic radiation of Chondrichthyes. The plesiomorphous condition of all …


Market Interactions And Competition Between Public And Private Oyster Production And Supplies From Other States, Ya-Ke Hsu Jan 1993

Market Interactions And Competition Between Public And Private Oyster Production And Supplies From Other States, Ya-Ke Hsu

Dissertations, Theses, and Masters Projects

Oyster production in Virginia has declined dramatically in the past ten years, causing Virginia oyster processors to rely increasingly on oyster supplies from other regions. In response to the industry problems, the Virginia Marine Resources Commission (VMRC) developed and began implementing an Oyster Fishery Management Plan (OFMP) in 1985. Primarily, the plan seeks to increase Virginia oyster production from both public and leased grounds. A large increase in production could significantly affect the oyster market. There is thus a need to understand the Virginia oyster market, which derives raw material supplies primarily from public and leased-grounds production and from other …


Movements And Behavior Of Wild And Head-Started Sea Turtles, John A. Keinath Jan 1993

Movements And Behavior Of Wild And Head-Started Sea Turtles, John A. Keinath

Dissertations, Theses, and Masters Projects

Flipper-tagging, aerial surveys, and satellite telemetry was used to investigate the occurrence, migratory routes, distances traveled, swimming speeds, diving behavior, and the relation of water temperature to movements and timing of migration of wild loggerhead (Caretta caretta) and Kemp's ridley (Lepidochelys kempii) sea turtles. The behavior and movements of head-started loggerhead turtles was investigated with satellite telemetry and compared to wild turtles. Flipper-tagged loggerhead and Kemp's ridley turtles inhabit Chesapeake Bay during the warm months and many return in subsequent seasons. Aerial surveys showed that loggerhead turtles migrate from south of Cape Hatteras to northern waters during May and June, …
