Phosphorescent Animal Forms Of Arkansas, Peggy Rae Dorris Jan 1971

Phosphorescent Animal Forms Of Arkansas, Peggy Rae Dorris

Journal of the Arkansas Academy of Science

Two phosphorescent animal forms, Euryurus sp. and Centruroides vittatus, were collected with a black light in an attempt to collect phosphorescent spiders. Both the millipede and the scorpion were easily observed by the bright phosphorescent yellow color which glowed in the presence of the black light

Rapid Electroosmosis Measurements, James O. Wear Jan 1971

Rapid Electroosmosis Measurements, James O. Wear

Journal of the Arkansas Academy of Science

A cell has been designed and built that allows for rapid measurement of volume moved in a definite time by electroosmosis. The cell is simple to use and is not very elaborate. Using a water jacket, the cell temperature can be controlled to ± 0.1° C. Measurements are presented for acetonitrile, dimethylformamide, and nitrobenzene at 25° C for applied voltages of 25, 50, 75, and 100 volts.

Physics And Environmental Studies, Joe M. Guenter Jan 1971

Physics And Environmental Studies, Joe M. Guenter

Journal of the Arkansas Academy of Science

To further implement the course curriculum for the Earth Science major and to constructively channel the current interest and concern with the environmental problems, the Department of Physical Science at the University of Arkansas at Monticello introduced a course entitled Environmental Studies this past spring. As it was necessary to offer both a general education Elementary Physics course in addition to the new course, it was decided to combine the two courses and use an approach similar to that of Edwin Marston, Queens College, Flushing, New York. Problems of conservation, pollution, and environmental quality were considered by the class whose …

Notes On The Algae Of Arkansas. 1. Chrysococcus, Kephyrion, Kephyriopsis, Pseudokephyrion And Stenokalyx, Richard L. Meyer Jan 1971

Notes On The Algae Of Arkansas. 1. Chrysococcus, Kephyrion, Kephyriopsis, Pseudokephyrion And Stenokalyx, Richard L. Meyer

Journal of the Arkansas Academy of Science

The genera Chrysococcus, Kephyrion, Pseudokephyrion and Stonokalyx have received some consideration by investigators in Europe and in the boreal forest and tundra-range regions of the United States. Many of the species are considered to be cold-water stenotherms, thus occurring more frequently in northern habitats. In the present paper 4 species of Chrysococcus, 4 species of Kephyroin, 2 species of Pseudokephyrion and 2 species of Stenokalyx from Arkansas are discussed.

Effects Of Urethan On Fish Epithelial And Fibroblast Cells In Vitro, Leland F. Morgans Jan 1971

Effects Of Urethan On Fish Epithelial And Fibroblast Cells In Vitro, Leland F. Morgans

Journal of the Arkansas Academy of Science

The effects of urethan on RTG-2 and FHM cells were studied in vitro, by using the mitotic index, it was determined that 0.3 percent urethan caused an increase in the rate of cell division while higher concentrations (0.6, 0.9, 1.2, and 1.5 percent) caused either a decrease in the rate or a cessation of cell division. Concentrations of urethan higher than 1.5 percent killed the cells. The mitotic index data also indicated that epithelial cells continued to divide at a higher concentration of urethan than did the fibroblast cells. The morphological effects of urethan on the two cell lines were …

Pre-Impoundment Limnological Study Of The Strawberry River In Northeastern Arkansas, Henry W. Robison, George L. Harp Jan 1971

Pre-Impoundment Limnological Study Of The Strawberry River In Northeastern Arkansas, Henry W. Robison, George L. Harp

Journal of the Arkansas Academy of Science

A study of pre-impoundment limnological characteristics of the Strawberry River was made from August, 1967 to June, 1968. Two collecting stations were established, one upstream which would not be inundated and a lower station which would be inundated when impoundment was complete. The Strawberry River was characterized by high alkalinity and pH, low carbon dioxide and turbidity, and adequate oxygen values. Plankton was characterized by limited numbers of Staurastrum, Gomphonema, and Rotatoria. Pool-riffle communities were ill-defined. Chironomidae, Oligochaeta and Ephemeroptera were dominant pool macroinvertebrates among 13 taxa collected. Of the 20 taxa collected in riffles Trichoptera, Ephemeroptera, Simuliidae and Chironomidae …

Ichthyofaunal Diversification And Distribution In The Big Creek Watershed, Craighead And Greene Counties, Arkansas, James T. Jenkins, George L. Harp Jan 1971

Ichthyofaunal Diversification And Distribution In The Big Creek Watershed, Craighead And Greene Counties, Arkansas, James T. Jenkins, George L. Harp

Journal of the Arkansas Academy of Science

Big Creek is a relatively small deltaic stream, in northeastern Arkansas, in an area of intense cultivation. Recently it has been dredged in the interest of flood control. Lost Creek and Mud Creek are the major tributaries of Big Creek and collectively drain the Big Creek watershed. The streams were found to have relatively low alkalinity, moderate carbon dioxide, adequate oxygen values, and relatively high turbidity. Channeling of Big Creek and Lost Creek has effectively destroyed distinct pool-riffle biocies and reduced the number of acceptable spawning areas. Lost Creek, also, receives effluent from residential dwellings, a secondary treatment sewage plant, …

A Theory Of Formal Organization And Its Acceptance By The Business Practitioner, Edgar Thomas Busch May 1970

A Theory Of Formal Organization And Its Acceptance By The Business Practitioner, Edgar Thomas Busch

Graduate Theses and Dissertations

Formal organization theory has evolved from the traditional school of thought through the scientific management and behavioral schools and into what is currently called open system theory. In spite of voluminous writing by the academician, no school of thought or no theory has been universally accepted. This may be due to the failure to consult the businessman who interprets and applies theoretical concepts to the practical situation. The purpose of this study was to help clear the theory jungle by determining the extent to which a sample of business practitioners agreed with basic factors of a comprehensive theory of formal …

Distribution Of Trace Elements In Impoundments, J. Nix Jan 1970

Distribution Of Trace Elements In Impoundments, J. Nix

Arkansas Water Resources Center Technical Reports

An investigation of the trace element content of two impoundments on the Ouachita River, Arkansas, was conducted. Common water quality parameters were followed in the reservoirs in an effort to determine the factors which were influencing the trace element concentration. The following trace metals were determined in both the particulate phase (retained by a 0.45 micron filter) and the soluble phase (passed by a 0.45 micron filter): iron, manganese, copper, cobalt, nickel, lead, chromium, and zinc. These measurements were made periodically for one and a half years. Results indicate that the chemical regime of the impoundments which were studied was …

Water Resources Planning Study For Arkansas And Oklahoma, L. R. Heiple, H. M. Jeffus Jan 1970

Water Resources Planning Study For Arkansas And Oklahoma, L. R. Heiple, H. M. Jeffus

Arkansas Water Resources Center Technical Reports

The purpose of this study is to make an appraisal of the local water resources in the Arkansas River Basin common to the two States of Arkansas and Oklahoma as defined by the Arkansas-Oklahoma Compact Committee (hereinafter referred to as "the Compact Committee"). A review, analysis, and correlation has been made of hydrologic data previously collected by others. Consideration is given to the evaluation at selected sites of the storage and potential use of existing water sources.

Glyptostrobus Europaeus (Brongn.) Heer In Arkansas, Eugene B. Wittlake Jan 1970

Glyptostrobus Europaeus (Brongn.) Heer In Arkansas, Eugene B. Wittlake

Journal of the Arkansas Academy of Science

Glyptostrobus europaeus (Brongn.) Heer, a fossil gymnosperm is found at a few locations in central North America, in deposits of the Eocene. This work cites previously reported localities and reports a new site at Hooker, Arkansas. This deposit appears to be the most abundant for specimens of G. europaeus in the Eocene of North America. History of the Hooker site, characteristics of the living species G. pensilis (Abel) Koch and G. europaeus is presented. Worldwide distribution of both species through time, is discussed. Specimens of many parts of the life cycle of G. europaeus are recorded and illustrated.
