Dietary Fat-Carbohydrate Combinations: Their Effects On Lipid Metabolism In Estrogen-Treated Rats, Beverly A. Clevidence
Dietary Fat-Carbohydrate Combinations: Their Effects On Lipid Metabolism In Estrogen-Treated Rats, Beverly A. Clevidence
Journal of the Arkansas Academy of Science
Female rats 4 weeks old were fed diets including beef tallow or safflower oil in combination with sucrose or rice starch. At 8 weeks of age, half the rats were orally administered 2 of estrogen (mestranol) in 5 μl of safflower oil and half were fed the vehicle only. After 10 to 14 days of estrogen treatment, rats were fasted and exsanguinated. Alterations were found in weight gain, liver weights, and levels of various lipids in plasma and liver. Most lipid levels were influenced by an interaction of mestranol with one of the dietary factors. No changes were observed in …

Problem Of Site Definition In Cultural Resource Management, Timothy C. Klinger
Problem Of Site Definition In Cultural Resource Management, Timothy C. Klinger
Journal of the Arkansas Academy of Science
The strategies employed by the Cache River Archeological Project, the Little Black Watershed Project, and the 1976 Village Creek Archeological Project with regard to site definition are compared and assessed. It is argued that both the Cache and Little Black Projects used unnecessarily restrictive definitions of cultural resources. The more liberal approach of the Village Creek Project enables both the archeological community and governmental agencies to interpret and assess better the significance and general extent of the archeological context of the cultural resource base.

Freshwater Mussel Shells As Indicators Of Seasonal Occupation Of Archaeological Sites: Review Of The Method, Robert H. Ray
Freshwater Mussel Shells As Indicators Of Seasonal Occupation Of Archaeological Sites: Review Of The Method, Robert H. Ray
Journal of the Arkansas Academy of Science
Seasonal occupation of sites and utilization of resources by aborigines is a subject of growing importance to prehistoric archeologists; however, relatively few satisfactory techniques are available for making the necessary determinations. Recent research in New Zealand has indicated the potential value of bivalve mollusks in subsistence-settlement pattern studies. A method for seasonal dating of prehistoric sites involving growth ring analysis of freshwater mussel shells and the potential application of this method in Ozark archeology are discussed.

Distributional Records Of Amphibians And Reptiles From Coastal Plain Of Arkansas, Edmond J. Bacon Jr., Zane M. Anderson
Distributional Records Of Amphibians And Reptiles From Coastal Plain Of Arkansas, Edmond J. Bacon Jr., Zane M. Anderson
Journal of the Arkansas Academy of Science
Distribution of amphibians and reptiles in the West Gulf Coastal Plain and Mississippi Alluvial Plain is not well known because extensive collecting has not been done in these areas and data in museums have not been published. New distributional records for three salamanders (Desmognathus fuscus brimleyorum, Manculus quadridigitarus, Plethodon glutinosus glutinosus) , two anurans (Rana areolata circulosa, Scaphiopus holbrooki holbrooki), and one snake (Lampropeltis doliata amaura) are presented. Additional collecting will be necessary to determine the exact range and status of the secretive species.
Metaphase Configurations In Drosophila: A Comparison Of Endemic Hawaiian Species And Non-Endemic Species, Frances E. Clayton
Metaphase Configurations In Drosophila: A Comparison Of Endemic Hawaiian Species And Non-Endemic Species, Frances E. Clayton
Journal of the Arkansas Academy of Science
The metaphase configurations of 400 strains from 63 species of Hawaiian Drosophila were determined from squash preparations of larval brain tissue or spermatogenic cells from adult testes. These karyotypes include configurations from seven species not previously described. Metaphases of 148 Hawaiian species have been recorded, including species of the "picture-wing" group, the "modified mouthpart" group, and the "bristle-foot" group. A comparison between Hawaiian species and non-endemic species was made on the basis of chromosome numbers and configurations. Among the Hawaiian species, 85.8% have retained the primitive haploid configuration of five rods and one dot compared with only 34.8% of species …
Influence Of Dietary Fats And Carbohydrates On Lipid Metabolism In Male And Female Rats, Marjorie Ellen Fitch
Influence Of Dietary Fats And Carbohydrates On Lipid Metabolism In Male And Female Rats, Marjorie Ellen Fitch
Journal of the Arkansas Academy of Science
Effects of dietary fats and carbohydrates on lipid metabolism in rats were studied. Male and female 4-week-old rats were divided into 8 groups and fed 4 fat-carbohydrate combinations (beef tallow or safflower oil, each with either sucrose or rice starch). After 4 weeks, animals were killed by exsanguination through the abdominal aorta and livers were removed. Plasma and liver cholesterol and phospholipids were determined qualitatively and quantitatively. Liver moisture, protein, and lipid and the fatty acid composition of the total liver lipid were determined quantitatively. Variations in growth, food efficiency, and lipid metabolism, particularly as manifested by the fatty acid …

Characteristics And Behavior Of Guineafowl And Domesticated Chicken Hybrids, Earl L. Hanebrink
Characteristics And Behavior Of Guineafowl And Domesticated Chicken Hybrids, Earl L. Hanebrink
Journal of the Arkansas Academy of Science
The description, behavior, and morphologic measurements are presented for two hybrid crosses of domesticated chicken and guineafowl. The ease at which gallinaceous birds hybridize might warrant a closer look at the classification system. Possibly the number of families in the superfamily Phasianoidea should be reduced as some other researchers suggest.
Hormone Receptor Site Maturation In The Secondary Sex Organs Of Immature Male And Female Rats, K. J. Thomas
Hormone Receptor Site Maturation In The Secondary Sex Organs Of Immature Male And Female Rats, K. J. Thomas
Journal of the Arkansas Academy of Science
The effect of a combined dose of pregnant mares' serum (PAAS) and human chor ionic gonadotropin (HCG) on male and female rats 2-25 days old was studied. Groups of animals were given injections for three days, then sacrificed on the fourth day. All injections were begun on the 2nd, 7th, 12th, 17th, and 22nd day of life. Ovaries, uteri, seminal vesicles (SV), and ventral prostate (VP) were removed, dissected free of fat, and weighed. Because uterine weight increased earlier than either SV or VP weight, the ability of the uterus to respond to exogenous estradiol and of the SV and …
Fishes Of The Fourche River In Northcentral Arkansas, Steve M. Bounds, John K. Beadles
Fishes Of The Fourche River In Northcentral Arkansas, Steve M. Bounds, John K. Beadles
Journal of the Arkansas Academy of Science
A survey of the fishes of Fourche River in northcentral Arkansas was made between June 1974 and March 1976. Field collections and literature records revealed that the river system was inhabited by 94 species of fish representing 21 families. The collected fishes represent both the Ozark and the lowland faunal groups. Fourteen species of Etheostoma and four species of Percina were collected. The records of Etheostoma asprigene and Elassoma zonatum represent extensions of the previously known ranges of these species within the state. Noturus gyrinus and Etheostoma histrio were recorded from the Black River system in Arkansas for the first …
Experimental Testing Program In Elementary Chemistry: A Preliminary Report, Billie G. Broach, Howard L. Hodges
Experimental Testing Program In Elementary Chemistry: A Preliminary Report, Billie G. Broach, Howard L. Hodges
Journal of the Arkansas Academy of Science
An experimental testing program is described which utilizes questions that are partly computer composed, in addition to a section composed by the instructor, and a retesting option to the student. Results from a trial of the program for one term indicate that (1) course grades were improved, (2) the student withdrawal failure rate was unaffected, and (3) the employed students took greater advantage of the retest than did the unemployed students.
Machismo Syndrome: A Residential Correlate Of Its Expression In A Mexican Peasant Community, J. M. Brueske
Machismo Syndrome: A Residential Correlate Of Its Expression In A Mexican Peasant Community, J. M. Brueske
Journal of the Arkansas Academy of Science
The Michaelson Goldschmidt hypothesis states that in peasant societies wherein male dominance is an ideal, matrilocal residence tends to encourage the expression of the machismo syndrome of behaviors. Recent ethnographic research in a Mexican peasant community supports the hypothesis by the finding that interpersonal violence (one measure of machismo) during a fiesta was perpetrated in every extreme instance by men who were residing matrilocally. The hypothesis thus effectively predicts, in this case, matrilocality as the variable most closely associated with the violent dimension of machismo.
Cave Fauna Of Arkansas: Selected Invertebrate Taxa, V. Rick Mcdaniel, Kenneth L. Smith
Cave Fauna Of Arkansas: Selected Invertebrate Taxa, V. Rick Mcdaniel, Kenneth L. Smith
Journal of the Arkansas Academy of Science
This report is the first in a series of reports describing the fauna of Arkansas caves. Included are notes accumulated during the past four years on nematomorphs, amphipods, isopods, diplopods, decapods, and a variety of insect taxa. In addition to indicated records of distribution, the ecological status of each species (as a cavernicole) is described as troglobitic, troglophilic, trogloxenic, or accidental. Several of the included species are reported for the first time from Arkansas.
Study Of Ultraviolet-Induces Chromatid And Chromosome Aberrations As A Function Of Dose In G1 Phase Vertebrate Tissue Cultures, Troy V. Orr, H. Gaston Griggs
Study Of Ultraviolet-Induces Chromatid And Chromosome Aberrations As A Function Of Dose In G1 Phase Vertebrate Tissue Cultures, Troy V. Orr, H. Gaston Griggs
Journal of the Arkansas Academy of Science
G1 phase A8 Xenopus laevis (toad) and V79B Cricetulus griseus (hamster) tissue cultures were used to observe the frequency of ultraviolet-induced chromosomal aberrations as a function of dose. When cultures are irradiated with ultraviolet light, visible aberrations are virtually absent until a threshold of approximately 80 ergs mm⁻¹ is reached. Aberrations then occur as a nonlinear function of dose. Chromatid aberrations are by far the most prevalent until doses in excess of 200 ergs mm⁻¹ are administered, at which point chromosome aberrations become common.

Semiquantitative Infrared Analysis Of Diketones And Anhydrides In A Reaction Mixture, Dominic T.C. Yang, F. H. Watson Jr., J. O. Lay, R. Getty
Journal of the Arkansas Academy of Science
The ozonolysis of a hydroxymethylene ketone yields a mixture of diketone and anhydride. Treatment of hydroxymethylene camphor with ozone affords, in addition to the expected camphor quinone, a surprisingly large amount of camphoric anhydride (56%) via Baeyer-Villager reaction. Use of infrared absorption to analyze the relative amounts of camphor quinone and camphoric anhydride in a reaction mixture was studied by comparing peak heights of their carbonyl stretching bands.
Scanning Electron Microscope Study Of Brachysclereids Of Pear (Pyrus Communis L.), Clarence B. Sinclair
Scanning Electron Microscope Study Of Brachysclereids Of Pear (Pyrus Communis L.), Clarence B. Sinclair
Journal of the Arkansas Academy of Science
The external surfaces of pear sclereids commonly are illustrated as covered with apertures. This SEAA investigation of the surface features has shown the surface to have few or no apertures. When the primary wall layer was removed the typical ramiform canal system was obvious. This observation confirms the often-ignored fact that the pitapertures of the secondary wall are not continuous with the primary wall. Hence, they do not show on the surfaces of the intact cell.
Composition Of Arkansas Grapes During Maturation, Cameron Jones, Dominic T.C. Yang, Thomas O. Whitley
Composition Of Arkansas Grapes During Maturation, Cameron Jones, Dominic T.C. Yang, Thomas O. Whitley
Journal of the Arkansas Academy of Science
Changes in organic acid and glucose content during maturation and ripening of grapes grown in Arkansas in 1973 are shown for four French hybrid varieties, S5279, S10878, SV23- 657, and S13053, and for four rotundifolia varieties, Scuppernong, Tarheel, Fry, and Magoon. In all varieties the concentrations of malates and tartrates were highest in the early stages of berry growth after veraison. During ripening the titratable acidity decreased and Balling and pH measurements increased. Although varieties reached maturity on different dates, changes in parameters followed similar curves typical for grapes of the species but occurring over a short period (Johnson and …

Continuation Of Mourning Dove Studies In Clark County, Arkansas, With Emphasis On Cyclical Behavioral Patterns, Thurman Booth, Fred L. Burnside Jr., Jan Burnside, Peggy Rae Dorris
Journal of the Arkansas Academy of Science
In conjunction with the U.S. Department of Interior, Fish and Wildlife Service, the Henderson State University Biology Department has continued a study of mourning doves in Clark County, Arkansas, with emphasis on cyclical behavioral patterns. Three hundred forty-three mourning doves were baited, trapped, and banded to obtain information concerning age, sex, populations, retraps, abnormalities, migrations, trap injuries, cyclical behavioral patterns, and other factors.
Electrophoretic Patterns Of Serum Proteins In Two Subspecies Of Odocoileus Virginianus, Greg S. Jackman, Phyllis J. Garnett
Electrophoretic Patterns Of Serum Proteins In Two Subspecies Of Odocoileus Virginianus, Greg S. Jackman, Phyllis J. Garnett
Journal of the Arkansas Academy of Science
Cellulose acetate electrophoresis revealed six monomorphic forms of serum protein in natural populations of two subspecies of white-tailed deer, Odocoileus virginianus virginianus from Tennessee and Odocoileus virginianus macroura from Arkansas. The fixed pattern of serum proteins in the two populations indicates a lack of genetic variation in the loci controlling these proteins. However, electrophoresis revealed different hemoglobin phenotypes in the two subspecies. This finding indicates that further study is needed to determine whether or not there are genetic differences in the hemoglobin forms
Soil Salinity Measurement By The Four-Electrode Probe Technique, K. Sriotai, John T. Gilmour
Soil Salinity Measurement By The Four-Electrode Probe Technique, K. Sriotai, John T. Gilmour
Journal of the Arkansas Academy of Science
The four-electrode probe method was tested on a Crowley silt loam soil in which salt type, salt content, and water content were varied. Theory associated with this technique of assessing soil salinity was verified. Equations were developed which quantified the relationships between soil electrical conductivity obtained by the four-electrode probe technique (EC), saturation extract (EC1), and 1:2 soil to water extract (EC2).

Aeration, Phosphorous, And Lime Affect Nitrogen Mineralization In Imperfectly Drained Forest Soils, M. S. Bhangoo, D. J. Albritton, Eugene Shoulders
Journal of the Arkansas Academy of Science
Unamended, limed, and phosphorus-enriched Caddo, Beauregard, and Wrightsville silt loams (A1 horizon) were incubated for six months at room temperature under two moisture regimes. At field capacity, unamended soils lost 0.7% of organic matter and converted 166 ppm of organic nitrogen to inorganic forms. Ninety-five percent of the converted nitrogen was present as N₄-H or NO₃-N. Limed and phosphorus-treated soils at field capacity lost about 1.0% of organic matter and accumulated 191 to 201 ppm of inorganic nitrogen. Submerged soils lost very little organic matter and accumulated only 24 to 28 ppm of inorganic nitrogen. There was a loss of …

This list extends the range of eight species. Distribution, ecological data if known, and references for their identification are included.
1974 Nonflood-Stage Chemical Loads Of The Buffalo River, Arkansas, Kenneth F. Steele, George H. Wagner
1974 Nonflood-Stage Chemical Loads Of The Buffalo River, Arkansas, Kenneth F. Steele, George H. Wagner
Journal of the Arkansas Academy of Science
Dissolved Ca, Mg, Na, K, Fe, Mn, and Zn loads of the Buffalo River generally show trends along the river attributable to changes in geology and vary with the season because of concentration by evapotranspiration and dilution by rain. Suspended material element loads show neither seasonal trends nor trends along the river. The Fe load for the river is predominantly in the suspended material, the Mn load is divided approximately evenly between dissolved and suspended material, and Ca, Mg, Na, K, and Zn are predominantly in the dissolved load.
Fishes Of The Cane Creek Watershed In Southeast Missouri And Northeast Arkansas, Bruce E. Yeager, John K. Beadles
Fishes Of The Cane Creek Watershed In Southeast Missouri And Northeast Arkansas, Bruce E. Yeager, John K. Beadles
Journal of the Arkansas Academy of Science
A survey of the fishes of Cane Creek in southeast Missouri and northeast Arkansas was made between 25 August 1974 and 16 July 1975. Field collections, literature records, fisherman reports, and museum specimens showed the fishes of Cane Creek to be composed of 90 species distributed among 20 families. Records of Lampetra aepyptera (Abbott), Hiodon alosoides (Rafinesque), Etheostoma histrio Jordan and Gilbert, and Percina uranidea (Jordan and Gilbert) were either the first records of these species in this stream or reaffirmed their presence. The fish collected were common to the Ozark, Ozark lowland, lowland, and wide-ranging faunal groups of Pflieger …
