Hydrology And Water Quality In The Central Kentucky Karst: Phase 1, James F. Quinlan, Donald R. Rowe

KWRRI Research Reports

Study of springs and cave streams has shown that heavy metal-rich effluent from a wastewater treatment plant can be traced to Hidden River Cave (beneath the city of Horse Cave) and thence 4 to 5 miles north to a group of 39 springs at 14 locations along a 5-mile reach of Green River. Nickel, chromium, copper and zinc in these effluent-bearing springs are in concentrations of as much as 30 times greater than other springs upstream and downstream from this reach, 20 times greater than the Green River, and 60 times greater than in shallow domestic wells between Horse Cave …

Estimating Merchantable Volume And Stem Residue In Four Timber Species: Ponderosa Pine, Lodgepole Pine, Western Larch, Douglas-Fir, United States Department Of Agriculture, Forest Service

Forestry

Presents tables and equations for estimating total cubic volumes of wood, wood residue, and bark for ponderosa pine, lodgepole pine, western larch, and Douglas-fir. Tables represent second-growth trees 80 years old or less, ranging in size from 1-1/2 inches d.b.h. to the maximum diameter measured for the respective species. The equations and tables provide a means for estimating wood bark residue volumes from tops, bole sections, and smaller submerchantable stems. Tables and equations can also be used to estimate total cubic volume for the size classes, species, and locale sampled.

Fisheries Report No 20 - Trawl Caught Fish And Crustaceans From Cockburn Sound, J. W. Penn

Fisheries Research Reports

Cockburn Sound is one of the few sheltered embayments near the Perth metropolitan area and as such has been subjected to increasing usage by both the general public and industry. Historically the Sound has been a major commercial fishing area from which much of the fresh fish for the metropolitan area has been caught. More recently, as well as providing a significant commercial catch, a major sport fishery has developed in the area.

The first commercial trawling operations in Cockburn Sound were undertaken in the early part of this century when horses were used to tow small nets on the …

Fisheries Report No 31 - Pecten Scallop Survey On Southern Geographe Bay, September 1976, D. I. Heald

Fisheries Research Reports

Reports of Pecten scallops in Geographe Bay in late 1975 were followed up by a preliminary stock survey in February 1976 using 1.22 m dredges and by a more extensive survey in September 1976 using 1.22 m and 2.25 m scallop dredges and a 0.5 m* Baird grab. Two very limited concentrations of scallops were located adjacent to rough ground. The best dredge catch rates were equivalent to 44 kg per hour per standard haul and the maximum grab catch was equivalent to a density of six scallops per square metre. The extremely rough terrain resulted in considerable damage to …

Fisheries Report No 27 - A Survey Of Recreational Usage Of South Coastal Estuaries Of Western Australia, N. Caputi, R C.J. Lenanton

Fisheries Research Reports

Over recent years, factors such as the State's population increase, a generally higher standard of living which enables people to have more leisure time, and better roads, particularly from the Eastern States of Australia, have all contributed towards an increase in the general recreational usage of the Western Australian south coast estuaries.

To aid proper planning of facilities to cater for an increasing number of visitors in these south coast estuaries, management agencies must be able to quantify the recreational usage in this group of estuaries.

This survey, therefore, attempts to identify and quantify the different recreational pursuits of visitors …

Fisheries Report No 24 - The Status Of The Salt-Water Crocodile In Some River Systems Of The North-West Kimberley, Western Australia, H. Messel, A. A. Burbidge, A. G. Wells, W. J. Green

Fisheries Research Reports

Counts were made of Salt-water Crocodiles (Crocodylus porosus) in the estuarine portions of four river systems in the northwest Kimberley, Western Australia - the Lawley, Mitchell, Roe-Hunter and Prince Regent. During the ten day survey 463 crocodiles were spotted, including 109 hatchlings. The maximum number of non-hatchling crocodiles present tin the four systems is estimated at 697. Very few large crocodiles were seen.

Populations were particularly small in the Lawley and Mitchell Rivers and the potential for recovery in this area is also small. Prospects for recovery in the Roe-Hunter and Prince Regent were a little better but further surveys …

Fisheries Report No 29 - The Predation Of Pot - Caught Western Rock Lobster (Panulirus Longpipes Cygnus) By Octopus, L M. Joll

Fisheries Research Reports

The losses to the western rock lobster fishery through the predation of pot-caught rock lobsters by octopus were estimated from samples taken on commercial boats in the four seasons 1972/73 - 1975/76. In most seasons approximately 200 000 legal-sized rock lobsters were lost. In the 1975/76 season the estimated financial loss from octopus predation was $392 000. The estimated losses probably represent minimum values. Studies of the biology and behaviour of octopus were carried out to examine the methods of detection, location and entry into rock lobster pots by octopus. The use of octopus traps in rock lobster pots significantly …

Mathematics In America: The First Hundred Years, Judith V. Grabiner

Pitzer Faculty Publications and Research

There are two main questions I shall discuss in this paper. First, why was American mathematics so weak from 1776 to 1876? Second, and much more important, how did what happened from 1776-1876 produce an American mathematics respectable by international standards by the end of the nineteenth century? We will see that the "weakness" -at least as measured by the paucity of great names- co-existed with the active building both of mathematics education and of a mathematical community which reached maturity in the 1890's.

Recent Parallels Between The Philosophy Of Science And Mathematics, Joseph Spradley

ACMS Journal 2004

Following World War I European philosophy of science formed an alliance with mathematics culminating in an attitude of certainty and autonomy that rejected all non empirical claims to truth and purported to make all science presupposition less. The rise and fall of logical positivism has been one of the major themes of of twentieth century thought and illustrates the danger of placing too much emphasis on science and mathematics as an ideal for all knowledge. The restriction of rational inquiry to the modes of scientific verification and the processes of mathematical logic was far too confining for the containment of …

Coral Populations And Growth Patterns: Responses To Sedimentation And Turbidity Associated With Dredging, Richard E. Dodge, J. Rimas Vaisnys

Marine & Environmental Sciences Faculty Articles

Analysis of coral growth patterns and populations in Bermuda reveals that living coral abundance on the reefs of Castle Harbor, a location where extensive dredging occurred during 1941- 1943, is much reduced in comparison to external North-South reefs. Dead corals, sampled in the harbor, have skeletal patterns of growth which are similar and which show a marked decline in growth for several years prior to death. For the brain coral genus Diploria, both D. strigosa and D. labyrinthiformis are fairly evenly represented on contemporary North-South reefs and in the assemblages of dead corals from Castle Harbor, while D. labyrinthiformis, …

The European Wasp : A New Threat To W.A, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

The European wasp was detected in Western australia for the first time in January and February 1977 in the metropolitan suburbs of Mosman Park, Cottesloe and Attadale.

So far it has only been found within an area of 8 km radius from Fremantle but the outer boundries of the infestation are still uncertain.

It is Department of agriculture policy to eradicate the European wasp, if possible, and to destroy all nests detected.

Impact Of Dredging In Tampa Bay 1976, Roy R. Lewis Iii

Reports

During the last 100 years four major types of dredging have impacted the bay: channel deepening, maintenance dredging, shell dredging, and dredging for landfill construction. These landfills have resulted in the loss of 44% of the original marine wetlands bordering Tampa Bay. Recent environmental concerns have halted landfill dredging and severely restricted maintenance dredging.

Asymptotic Properties Of A Nonlinear Diffusion Process Arising In Articular Cartilage, Van C. Mow, Jerome Eisenfeld

Mathematics Technical Papers - Archive

There has been considerable effort put forth to analyse degenerative Joint diseases in terms of the principles of mechanics and hydrodynamics [8]. This effort has led to mathematical models which are systems of nonlinear partial differential equations (see e.g., [6] and [7]). The mathematical models are based on assumptions concerning the nature of the physical system which are not a priori known. Therefore laboratory experiments are performed with an eye towards validating the mathematical models. This paper deals with a particular mathematical model, a nonlinear diffusion equation, which has been proposed by Mow and Monsour [4], [5] to describe the …

Stability Of Differential Systems With Impulsive Perturbations In Terms Of Two Measures, S. Leela

Mathematics Technical Papers - Archive

The study of differential systems of the form (1.1) [see pdf for notation] where [see pdf for notation] denotes the distributional derivative of [see pdf for notation], a function of bounded variation (that is, differential systems with impulsive perturbations, also called measure differential equations), is both interesting and important because most models for biological neural nets,pulse frequency modulation systems, automatic control problems with impulsive inputs and many physical processes are best described by such equations [1-3,8,10,12,13]. Since the solutions of (1.1) are discontinuous (that is, functions of bounded variation), the investigation of the stability properties of (1.1) by the usual …

Variables Associated With Breeding Waterfowl On South Dakota Stock Ponds, Jay A. Roberson

Electronic Theses and Dissertations

Use of stock watering ponds by indicated breeding pairs of waterfowl was measured in the western two-thirds of South Dakota from 1973 to 1976. Multiple regression and discriminant analyses were used to describe the habitat associated with pairs of each species. Habitat variables explained 35-47 percent of the variation in pairs having small home ranges and 26-35 percent of the variation in pairs having large home ranges. Shoreline distance account for more variation in mallard (Anas Platyrhmchos) and blue-winged teal (A. discors) pairs than any other single variable. Ponds used by these pairs and shoreline distances that averaged 590 m …

Population, Home Range, And Dispersal Of Red Foxes In East-Central South Dakota, James D. Sweeting

Electronic Theses and Dissertations

The population, dispersal movements and summer home range of red foxes (Vulpes vulpes) were studied in east-central South Dakota during 1974 and 1975. The spring population density of foxes on a 23,319 ha study area declined from 9.2 families/township in 1974 to 7.6 families/township in 1975. Fifty-four percent of 130 foxes tagged in spring, 1974 and 1975 were recovered during the first year following tagging. Hunting and trapping accounted for 18.0 and 77.8 percent, respectively. Recoveries revealed that dispersing juvenile male foxes were more mobile than juvenile females; juvenile foxes traveled a mean distance of 39 km for males and …

Complex Systems Faculty Publications and Presentations

Aggregated forms of deoxyhemoglobin S were examined with a field emission transmission electron microscope. Images of isolated helical fibers were obtained from sickled cell lysates stained directly on the electron microscope grid. Optical and digital analyses of the electron micrographs showed that the fibers are similar to those characterized by J.T. Finch, M. F. Perutz, J. F. Bertles, and J. Dobler [(1973) Proc.NatL Acad. Sci. USA 70, 718-7221 in that they consist of stacked discs each composed of six hemoglobin molecules. The fibers exhibit an outer diameter of 160-170 A and an inner diameter of about 60 A with an …

Estimate Of Production By A Population Of Fathead Minnows, Pimpephales Promelas, In A South Dakota Prairie Wetland, Ronald D. Payer

Electronic Theses and Dissertations

Estimates of production and population densities were obtained for an autochthonous population of fathead minnows, Pimephales promelas Rafinesque, in a South Dakota prairie wetland. The study was conducted from May to September of 1976. Population estimates were obtained using a Schnabel-type mark and recapture model. Fish were marked either by fin clipping or granular fluorescent pigments driven into the dermal tissue. Production estimates were derived both arithmetically and graphically. The estimated population of adult fathead minnows declined from 194 in May and June to 26 in July. Production by adults was estimated at 0.10 kg, or 0.0007 gm/m²/yr. The population …

Digestibility Of Common Forage Plants And Energetic Requirements Of The Black-Tailed Prairie Dog, Maureen A. Beckstead

Electronic Theses and Dissertations

Black-tailed prairie dogs (Cynomys ludovicianus) assimilated 51.5 percent of the wheatgrass (Agropyron intermedium) they consumed; thus, they would have to consume 0.148 kcal · g-1 · day-l in order to obtain the 0.076 kcal · g-1 · day-1 they would require to maintain their weight. Prairie dogs assimilated 31.5 percent of the buffalograss/blue grama mixture (Buchloe dactyloides/Bouteloua gracilis) they were fed. They would have to consume 0.229 kcal · g-1 · day-1 of this forage to assimilate 0.072 kcal · g-1 · day-1 and maintain their weight. The proximate composition of forages fed in feeding trials was similar to that …

Wildlife Habitat Evaluation Of The Unchannelized Missouri River In South Dakota, James R. Clapp

Electronic Theses and Dissertations

Areas of eight habitats were identified, delineated, and measured along the unchannelized Missouri River in South Dakota. Agricultural and urban developments existed on 60 percent of the land within 1 km of the river. Six habitat types made up the non-developed land in the study area: cottonwood-dogwood (16 percent), cottonwood-willow (9 percent), elm-oak (7 percent), cattail marsh (3 percent), sand dune (3 percent), and sand bar (1 percent). All non-developed habitats except sand bar were sampled to obtain vegetative composition and to determine their value to wildlife. The value of each habitat to nine faunal groups of wildlife was subjectively …

Biology Of The Porcupine (Erethizon Dorsatum) In Northwestern South Dakota, Judith Johnson

Electronic Theses and Dissertations

The summer home ranges, food habits, cover preferences, population dynamics, metabolic rates, growth rates, and taxonomic characteristics were determined for porcupines (Erethizon dorsatum) in northwestern South Dakota. The summer home ranges were 158.2 ha for adult females, 90.4 ha for juveniles, and 57.9 ha for adult males. The population was 34 percent adult males, 16 percent juvenile males, 34 percent adult females, and 15 percent juvenile females. The preferred daytime cover choice was silver buffaloberry (Shepherdia argentea), followed by snowberry (Symphoricarpos occidentalis), earth dens, forbs, and low brush. Shrubs were the most important item in the diet, then trees, forbs, …
