Arkansas Water Resources Center Technical Reports
Four experimental filter fields were constructed with built-in monitoring equipment in Nixa soils. These soils contain many chert fragments and a fragipan about 60 cm below the soil surface. The fragipan restricts downward movement of water and is the designlimitingfeature. The four filter fields were: 1. A "standard" filter field, 76 cm deep. The bottom of the trench was in the fragipan. 2. A "modified standard" filter field, 30 cm deep. The bottom of the trench was above the fragipan. 3. A "modified pressure" filter field, 40 cm deep. The bottom of the trench was above the fragipan. In addition, …

Arkansas Water Resources Center Technical Reports
Two experimental septic tank filter fields were constructed with built-in monitoring equipment in Nixa soils. These soils contain many chert fragments and a fragipan about 60 cm deep which restricts downward water movement and is the design-limiting feature. The standard filter field (76 cm deep) was built into the fragipan and the modified standard filter field (30 cm deep) was placed above it. During 30 months' observation, the modified standard performed better than the standard filter field. Maximum rise of effluent in the standard and modified standard came within 11 and 19 cm of the soil surface, respectively. Performance of …
Nutrients And Acid In The Rain And Dry Fallout At Fayetteville, Arkansas (1980-1982), George H. Wagner, Kenneth F. Steele
Nutrients And Acid In The Rain And Dry Fallout At Fayetteville, Arkansas (1980-1982), George H. Wagner, Kenneth F. Steele
Arkansas Water Resources Center Technical Reports
Wet and dry fallout at Fayetteville, Arkansas have been collected separately and analyzed since April, 1980. The precipitation-weighted-average pH for two yearly periods of rainfall were 4.72 (6/80-5/81) and 4.75 (6/81-5/82). This corresponds to a concentration of the acid ion, H+, of about 18 parts per billion (ppb). Pure water in equilibrium with the CO2 of the air would have a pH of 5.65 (2.2 ppb of H+). The range of pH during this two year period was 3.86-7.74(140-0 ppb H+) for the rainfall. Aqueous extracts of the dry fallout were always in the 6.75-7.87 pH range, i.e., neutral to …

Mensural Discrimination Of The Skulls Of Arkansas Peromyscus, V. Rick Mcdaniel, C. Renn Tumlison, Phil Mclarty
Mensural Discrimination Of The Skulls Of Arkansas Peromyscus, V. Rick Mcdaniel, C. Renn Tumlison, Phil Mclarty
Journal of the Arkansas Academy of Science
Twelve parameters were measured on skulls of four species of Peromyscus from Arkansas. Univariate statistical tests, multivariate analyses of variance, and principal axis factor analyses were performed on the data set and/or subsets in a search for species-level discriminating characters. Total length of skull was found to discriminate between skulls of P. maniculatis, P. leucopus, and a combined group of P. attwateri and P. gossypinus. Furthermore, the ratio of interorbital width and length of nasal bone was found to adequately discriminate between skulls of P. attwateri and P. gossypinus.

Relationship Between Physical Conditioning And Plasma High Density Lipoprotein-Cholesterol Concentration, Leland F. Morgans, Dennis A. Baeyens, Manford D. Morris
Journal of the Arkansas Academy of Science
Five subjects (three females and two males) took part in an exercise regimen in order to determine if aerobic exercise results in an increase in high-density lipoprotein-cholesterol levels (HDL-C) in the plasma. The exercise regimen consisted of running three miles a day, five days per week for six months. Running speed was at such a pace that the subjects attained a minimum of 60% of their maximal heart rate reserve (MHRR). Before the training program began the following parameters were measured in all of the subjects: height, weight, percent body fat, maximal oxygen consumption (Vₒ₂ max), vital capacity, resting heart …

Journal of the Arkansas Academy of Science
Methods and procedures for artificially spawning the female grass carp (Ctenopharyngodon idella) X male bighead carp (Aristichthys nobilis) are presented. Broodstock selection and treatment, hormone injections, ovulation, fertilization, hatching techniques and stocking rates are discussed. This paper outlines the procedures necessary to successfully produce hybrid grass carp

Two species in two genera were reported in the literature as occurring in Arkansas. Based on distribution records in …
Computer Pattern Recognition Of Action Potentials, Ronald S. Remmel
Computer Pattern Recognition Of Action Potentials, Ronald S. Remmel
Journal of the Arkansas Academy of Science
A general method of pattern recognition was applied to the problem of recognizing extracellularly-recorded neuronal action potentials in the presence of noise and other pulses. A PDP1 1/23 performed the calculations. There were four stages: 1.) A bandpass filter attenuated noises; 2.) the data input program digitized the signal every 55 μsec. If the signal exceeded a threshold, 12 samples of the signal and the time were written onto the disk; 3.) the pulse discriminating program recognized an action potential by fitting the 12 points with this function: v(t) = (a + bt + ct² ) exp(-t/Ƭ). For each pulse …
Phytoplankton Community Structure In Dardanelle Reservoir, Arkansas, 1975-1982, John D. Rickett, Robert L. Watson
Phytoplankton Community Structure In Dardanelle Reservoir, Arkansas, 1975-1982, John D. Rickett, Robert L. Watson
Journal of the Arkansas Academy of Science
Phytoplankton data were collected with standard equipment and procedures over an eight-year period (1975-1982) in Dardanelle Reservoir, Arkansas. Community abundance and diversity at the genus level are described. Sixty-five genera representing 35 families and five divisions were identified. Total phytoplankton abundance and diversity were quite uniform among the stations but fluctuated considerably with time. These fluctuations did not correspond clearly with season. Dominant taxa were seasonal, though, with diatoms being usually dominant in January, April and October, and blue-greens dominant in July. The phytoplankton community structure has not been significantly altered by the operation of ANO Unit I.
Zooplankton Community Structure In Dardanelle Reservoir, Arkansas, 1975-1982, John D. Rickett, Robert L. Watson
Zooplankton Community Structure In Dardanelle Reservoir, Arkansas, 1975-1982, John D. Rickett, Robert L. Watson
Journal of the Arkansas Academy of Science
Zooplankton was collected at 10 stations in Dardanelle Reservoir from 1975 to 1982. Current data were compared to a five-year preoperational study phase. Rotifer taxa strongly dominated the community. Overall abundance was higher, variety about the same and diversity lower than those of comparable studies. Thermal discharges caused a dominance shift between two rotifer taxa, slightly depressed abundance and variety, did not noticeably affect diversity and elevated the phytoplankton/zooplankton ratio. Heated effluent also stimulated stronger fluctuations in abundance and variety. Other studies indicate that in upper sections of the Arkansas River drainage, microcrustaceans dominate lake habitats whereas rotifers dominate river …
Fishes Of The Antoine River, Little Missouri River System, Southwestern Arkansas, Henry W. Robison, Elaine Laird, Darryl Koym
Fishes Of The Antoine River, Little Missouri River System, Southwestern Arkansas, Henry W. Robison, Elaine Laird, Darryl Koym
Journal of the Arkansas Academy of Science
The fishes of the Antoine River (Little Missouri River system) in southwestern Arkansas were surveyed from September, 1980 - June, 1982. Thirty-four field collections plus literature and museum records, revealed a total of 60 species in 29 genera representing 16 families to presently inhabit the river system. Comments are presented on life history aspects, systematics and occurrence of fishes in the study area.
