Infrared Spectroscopy Of Nickel And Iron Geoporphyrins, Kewei Xu

Theses, Dissertations and Capstones

The first assignments of a number of vibrational modes to the infrared spectra of nickel and iron porphyrins are presented. The purpose of this work was to establish a library of reference spectra which can be used in the identification of geoporphyrins from coal. The infrared regions of 1700-1200 cm·' and 1200-600 cm·1 are informative and display a rich array of skeletal and alkyl substituent modes. The detailed analyses indicate that nickel and iron complexes of the four etioporphyrin (Etio) I-IV isomers exhibit notable differences at certain positions, especially in the 800-700 cm·' and 1000-900 cm·' subregions, which should enable …

Plateau Tank Apparatus For The Study Of Liquid Bridges, Andrew Resnick, J. Iwan D. Alexander

Physics Faculty Publications

An apparatus has been constructed and used to study the equilibrium and dynamical behavior of liquid bridges under reduced effective gravity. Liquid bridges are created and manipulated using six independent computer controlled stepper motors which drive linear motion tables. The bridges are visualized with a high magnification coherent Fourier optical system and in an orthogonal view using incoherent white light. By calibrating a density hydrometer and measuring the interfacial energy between the bridge and bath, reliable Bond numbers as low as 10−4 can be created and held stable for extended periods of time. Dimensional control of the liquid bridges approaches …

Barium Chronologies From South Florida Reef Corals - Environmental Implications, D. Anderegg, Richard E. Dodge, Peter K. Swart, L. Fisher

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Benthic algal blooms (e.g., Codium isthmocladum) have become increasingly common on reefs and hardgrounds of Southeast Florida. The contribution from possible responsible nutrient sources, including natural upwelling and local pollution, has not been quantified. In an attempt to differentiate each potential source, lattice-bound barium concentrations in the skeletons of two common Southeast Florida stony coral species (Montastraea faveolata and Solenastrea bournoni) were measured by isotope dilution inductively coupled mass spectrometry (ICP/MS). Specimens were collected offshore between 26˚01'-57'N at shallow (10m) and deep (20m) reefs. X-rays of skeletal slabs revealed annual density bands which guided annual and subannual …

Environmental Assessment For Coal Planning Decisions In The Carbon Basin Area Of The Great Divide Resource Area, United States Department Of The Interior Bureau Of Land Management

Environmental Assessments (WY)

In 1982, a federal coal lease was issued for approximately 60% of the federal coal lands located in the Carbon Basin. Because this lease was still in effect at the time the current BLM land use plan (the Great Divide Resource Area Resource Management Plan-RMP-1990) covering the Carbon Basin area was prepared, it was exempt from the coal screening/planning requirements. However, development of this lease was never pursued and the lease expired in 1992. Also at the time the Great Divide RMP was prepared, there was no other interest expressed by industry in obtaining federal coal leases in the area. …

Mathematics And Values: Can Philosophy Guide Projects?, Michael H. Veatch

ACMS Journal 2004

The philosophy of mathematics has provided insight on questions of foundations and mathematical truth; however, it has not been very fruitful in guiding the practice of mathematics. This paper attempts to find points of contact between a Christian worldview and the choice of mathematical projects and methods. Three areas are considered: (i) dubitability in current research, (ii) the intrinsic value of contemporary mathematics to contemporary society, and (iii) the affirmation of human value in the use of mathematics. Finally, a framework for valuing mathematics is proposed as an encouragement to think more deeply about how a Christian might choose a …

United States Department of Commerce: Staff Publications

Information on reactions of delphinids to biopsy sampling and healing of associated biopsy wounds is limited. Results presented here report on the behavioral responses of free-ranging bottlenose dolphins (Tursiops truncatus) to remote biopsy sampling procedures, and provide information on stages of surgical biopsy wound repair. Biopsy samples of free-ranging dolphins were collected between February–May 1992 in Galveston Bay, Texas, using a sterilized corer-tipped bolt, launched from a crossbow. A total of 8 direct ‘hits’ were documented, 4 hits (50%) in which a tissue sample was obtained, 2 hits (25%) from which no sample was retrieved, and 2 hits …

First Estimates Of Vaquita Abundance, Jay Barlow, Tim Gerrodette, Greg Silber

United States Department of Commerce: Staff Publications

The abundance of the only population of vaquitas, Gulf of California harbor porpoise (Phocoena sinus), is estimated from four surveys conducted in Mexico between 1986 and 1993, using a variety of methods. A line-transect approach was applied, using some parameters estimated from a related species, the harbor porpoise (Phocoena phocoena). Vaquita abundance is estimated as 503 (CV = 0.63) from 1986-1988 boat surveys, 885 (CV = 0.50) from 1988-- 1989 aerial surveys, 572 (CV = 1.43) from a 1991 aerial survey, and 224 (CV = 0.39) from a 1993 ship survey. A weighted log-linear regression in …

United States Department of Commerce: Staff Publications

A boat survey was conducted from 5 to 26 June 1993 to estimate the abundance of the Amazon river dolphin (Inia geoffrensis) and the tucuxi (Sotalia fluviatilis) along ca. 120 km of the Amazon River bordering Colombia, Peru, and Brazil. Two survey methods were used: line transects during 5 d and strip transects during 15 d. The line transects were used to estimate the abundance of both species in the main channels of the Amazon at distances greater than 200 m from river banks and islands, and strip transects were used to estimate abundance in the …

First Record Of Common Moorhen Nesting In South Dakota, William A. Meeks, Kenneth F. Higgins

United States Geological Survey: Staff Publications

The common moorhen (Gallinula chloropus) is widespread in North America, but is not very abundant throughout its range (Greij 1994, Common Moorhen, Pages 145-157 in Tacha and Braun [eds.] Migratory Shore and Upland Game Bird Management in North America, Allen Press, Lawrence). In North Dakota its status is accidental (Konrad 1983, Prairie Nat. 15:144); in South Dakota it is considered a casual visitor and a probable breeding species (South Dakota Ornithologists' Union 1991, The Birds of South Dakota, Northern State University Press, Aberdeen; Peterson 1995, The Breeding Bird Atlas of South Dakota, Northern State University Press, Aberdeen).

A Land-Use And Water-Quality History Of White Rock Lake Reservoir, Dallas, Texas, Based On Paleolimnological Analyses, J. Platt Bradbury, Peter C. Van Metre

United States Geological Survey: Staff Publications

White Rock Lake reservoir in Dallas, Texas contains a 150-cm sediment record of silty clay that documents land-use changes since its construction in 1912. Pollen analysis corroborates historical evidence that between 1912 and 1950 the watershed was primarily agricultural. Land disturbance by plowing coupled with strong and variable spring precipitation caused large amounts of sediment to enter the lake during this period. Diatoms were not preserved at this time probably because of low productivity compared to diatom dissolution by warm, alkaline water prior to burial in the sediments. After 1956, the watershed became progressively urbanized. Erosion decreased, land stabilized, and …
