Aspects Of Larval Ecology Of Squilla Empusa (Crustacea, Stomatopoda) In Chesapeake Bay, Steven G. Morgan

OES Faculty Publications

Larvae of Squilla empusa were collected from the plankton and were laboratory-reared in 16 combinations of temperature and salinity to determine their tolerances. Larvae survived longer and molted more frequently when reared at 25%, and 20° or 25° C, which corresponds to the natural conditions of Chesapeake Bay when the larvae were collected.

A 2 year planktonic survey conducted in the lower region of the bay by the Virginia Institute of Marine Sciences was compared with a survey made at the bay mouth in 1976. The seasonal occurrence of Squilla empusa larvae extended from the last week of July until …

Causality, Determinism, And The Mind-Brain Problem, Jeffrey C. Schank

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The problem of causality, determinism, and mind and brain are discussed, and new solutions are offered. To begin, a pragmatic structuralism is assumed, asserting the functional equivalence of mind and brain activity. A problem-solving model of mind-brain activity is defined, employing the mathematical theory of probablistic automata. With this model it can be determined whether mind-brain activity is deterministic. This is accomplished if an adequate definition of strict causality is developed. Logical models of strict causality which define the causal relation in terms of "material implication" or "strict implication" are rejected. Causal relativity is assumed, and certain systemtheoretical assumptions are …

The Applicability Of Torgerson's Concept Of Fiat Measurement In Developmental Stages Of The Social Sciences, Christine V. Zavgren, S. J. Lambert

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The concept of "fiat measurement" is an alternative to fundamental and derived measurement. This concept is believed to be more descriptive of measurement in the social sciences, where in most cases theories as well-formed as those in the physical sciences do not exist. In fiat measurement an index or measurement of a concept is assumed to be representative of that concept. However, the representation between a measurement scale and the theoretical concept cannot be proven. Although fiat measurement is descriptive of much current work in social sciences, it is shown to be a problematic concept because of its arbitrariness, lack …

The Structures Of Scientific Relativism, Charles J. Dougherty

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Few recent works have generated as much intellectual discussion as Thomas S. Kuhn's The Structure of Scientific Revolutions. Yet given the impact this book has had on our understanding of science-its role in the demise of logical positivism, in the current outpouring of interest in the history of science, and in changes in science education - perhaps it is time now, some ten years after Kuhn's provocative Postscript, for still another look at his thesis. That is the purpose of this study. First, those elements of Kuhn's book which committed him to a scientific relativism are reconstructed. Secondly, …

The Association Of 5.8 S With 28s Ribosomal Rna, Nandita Banerjee

Chemistry & Biochemistry Theses & Dissertations

5.8S rRNA is a low molecular weight ribosomal RNA which is noncovalently bonded to the larger ribosomal subunit 28S rRNA; through its 3' end and through its 5' end. This interaction is an integral part of the ribosome, and plays an important role in the ribosome structure and function.

There is a high degree of homology between the 5.8S rRNA primary structures of rat, turtle and chicken. The base sequence of rat 5.8S rRNA differs only in one position from that of turtle and in three positions fr.om that of cl1.icken. Tl1ere is a single purine substitution at the 5' …

Low Rainfall Pasture Programme, M Ewing

Experimental Summaries - Plant Research

The Headquarters of dry land pasture project was transferred to Merredin from Perth for the 1980 season. The aim of the programme is to ascertain the place that legume pasture might play in the dryland farming system. It is aimed to test and introduce improved varieties of pasture species and develop management systems which will improve pasture production and persistence in the low rainfall areas of the wheatbelt. 1.

Phytoplankton Studies Within The Virginia Barrier Islands I. Seasonal Study Of Phytoplankton In Goose Lake, Parramore Island, Harold G. Marshall

Biological Sciences Faculty Publications

The phytoplankton of Goose Lake, an oligohaline lake on Parramore Island, was studied for one year. The populations consisted primarily of ultraplankton and nanoplankton-sized forms with diatoms and chlorophyceans dominant most of the year. A general pattern of seasonally higher cell concentrations in early summer and fall was noted, with an unidentified ultraplankton-sized component prominent throughout the collection period. A list of 154 species is given.

The Effects Of N-Serve On The Availability Of Urea And Ureaformaldehyde Nitrogen On Lolium Perenne L., Ronald E. Schroll

Masters Theses

Laboratory experiments were conducted to determine the effect of "N-Serve" (DOW) on the availability of urea nitrogen and the subsequent greening effect on perennial ryegrass (Lolium perenne L.) seedlings as compared to the availability of nitrogen and subsequent greening from a controlled release ureaformaldehyde fertilizer. A low organic matter sandy loam soil and a high organic matter clay loam soil were used in this study. Soil treatments of urea and ureaformaldehyde fertilizers were applied and incorporated at concentrations of 0, 25, 38, and 50 ppm-N. N-Serve at concentrations of 0.25, 0.50, and 1.0 ppm active ingredient were applied and …

Predation Of Upland Game And Its Management, Roger Wells

Great Plains Wildlife Damage Control Workshop Proceedings

There is probably no greater topic that elicits greater emotion in public wildlife discussions than that of predation. A variety of groups each with their own particular special interest surround the topic.

Some advocate complete protection of predators on the premise that their activities merely result in a "balance of nature." The opposite viewpoint argue just as strongly for the total elimination of Predators of valued wildlife in order to have greater number for man's enjoyment.

Polymorphisms, Linkage And Mapping Of Four Enzyme Loci In The Fish Genus Xiphophorus (Poeciliidae), D C Morizot, M J Siciliano

Faculty, Staff and Student Publications

Electrophoretic variants at four additional enzyme loci--two esterases (Est-2, Est-3), retinal lactate dehydrogenase (LDH-1) and mannose phosphate isomerase (MPI)--among three species and four subspecies of fish of the genus Xiphophorus were observed. Electrophoretic patterns in F1 hybrid heterozygotes confirmed the monomeric structures of MPI and the esterase and the tetrametric structure of LDH in these fishes. Variant alleles of all four loci displayed normal Mendelian segregation in backcross and F2 hybrids. Recombination data from backcross hybrids mapped with Haldane's mapping function indicate the four loci to be linked as Est-2--0.43--Est3--0.26--LDH-1--0.19--MPI. Significant interference was detected and apparently concentrated in the Est-3 …
