Initial Growth and Survival of Bluegills and Black Bullheads Stocked With Largemouth Bass in South Dakota Ponds

Initial growth and survival rates were estimated for bluegills (Leponis macrochirus) and black bullheads (Ictalurus melas) stocked simultaneously with largemouth bass (Micropterus salmoides) in ponds throughout South Dakota. Mean first year survival for bluegills and black bullheads stocked in eastern South Dakota ponds was 28.6% and 67.7%, respectively. Differences in first year bluegill growth throughout the state were not detected. Total lengths for bluegills averaged 52.4 mm after one growing season statewide and 137.1 mm after two growing seasons in southeastern South Dakota ponds. Significant (P\u3c.05) geographical differences in first year growth of black bullheads were detected with mean lengths ranging from 67.7 mm in northwest ponds to 115.5 mm in southeast ponds. The average total length for black bullheads after two growing season in southeastern South Dakota ponds was 215.2 mm. The combined effects of pH, turbidity, and bicarbonate alkalinity accounted for 67.5% of the variation in first year bluegill growth. The pond parameters total number of growing days, fish present prior to stocking, and pond surface area when combined accounted for 73.9% of the variation in first year black bullhead growth. Differences in bluegill relative weight values were not detected throughout South Dakota; the average for the state was 105.2. Mean black bullhead condition factors (K) for fish with total lengths between 128 and 191 mm were 1.85 and 1.45 for pre- and post-spawning periods, respectively. Bullheads probably spawned between 29 May and 26 June 1980

Monitoring and Evaluating the Influences of Class V Injection Wells on Urban Karst Hydrology

The response of a karst aquifer to storm events is often faster and more severe than that of a non-karst aquifer. This distinction is often problematic for planners and municipalities, because karst flooding does not typically occur along perennial water courses; thus, traditional flood management strategies are usually ineffective. The City of Bowling Green (CoBG), Kentucky is a representative example of an area plagued by karst flooding. The CoBG, is an urban karst area (UKA), that uses Class V Injection Wells to lessen the severity of flooding. The overall effectiveness, siting, and flooding impact of Injection Wells in UKA’s is lacking; their influence on groundwater is evident from decades of recurring problems in the form of flooding and groundwater contamination. This research examined Class V Injection Wells in the CoBG to determine how Injection Well siting, design, and performance influence urban karst hydrology. The study used high-resolution monitoring, as well as hydrologic modeling, to evaluate Injection Well and spring responses during storm and baseflow conditions. In evaluating the properties of the karst aquifer and the influences from the surrounding environment, a relationship was established between precipitation events, the drainage capacity of the Injection Wells, and the underlying karst system. Ultimately, the results from this research could be used to make sound data-driven policy recommendations and to inform stormwater management in UKAs

‘SELBY WARREN: AUSTRALIAN BUSH ARTIST AND TRIBE OF ONE’

In this thesis I have looked at the life and works of the Australian self-taught artist, Selby Warren, who was born in 1887 and spent his whole life in rural New South Wales near the small, inland city of Bathurst. Warren was typical of many self-taught artists in that he was completely untrained in art, unaware of the artworld and, having worked as a labourer, only began painting in earnest after semi-retiring at the age of seventy-six. Almost a decade later he was discovered by an art lecturer who introduced him to a city dealer and gallery owner and his work was exhibited in commercial galleries in Sydney, Melbourne and Brisbane. During this brief (three year) period he was reasonably well known in art circles but this soon ended and he spent the remaining years of his life in his home town of Trunkey Creek. He died in 1979 aged 91. Warren exemplified the experiences shared by many self-taught artists both in Australia and overseas. I consider the events involved in the growth of interest in self-taught art and the ensuing influences it (and related phenomena like primitivism and primitive art) had on approaches to modern art movements from the turn of the twentieth-century until about 1980 in Europe, America and Australia. George Melly’s idea of the ‘tribe of one’ 1 and how it relates to artists like Warren and his ilk is explored. An analysis of Warren’s paintings and those of his Australian, European and American contemporaries is provided in a response to the view that it is the sometimes unusual lives rather than the output of self-taught artists that is too often used in the discussion of a unique, but not uncommon, art form

Revision of the Jefferson City formation in the Rolla quadrangle

The geology of the Rolla quadrangle was mapped by Lee in 1912. At that time all the dolomitic strata above the Roubidoux and beneath the Carboniferous formations in this area were placed in the Jefferson City. A more detailed study of the stratigraphy of the whole Ozark region by Ulrich has shown that some of the strata which had been included in the Jefferson City formation on lithologic grounds are not equivalent to the dolomites in the type section at Jefferson City, Missouri --Introduction, page [1]

Planet X probe: A fresh new look at an old familiar place

Planet X Probe utilizes a Get Away Special (GAS) payload to provide a large student population with a remote Earth sensing experimental package. To provide a cooperative as well as a competitive environment, the effort is targeted at all grade levels and at schools in different geographical regions. LANDSAT capability allows students to investigate the Earth, its physical makeup, its resources, and the impact of man. This project also serves as an educational device to get students to stand back and take a fresh look at their home planet. The key element is to treat the familiar Earth as an unknown planet with knowledge based only on what is observable and provable from the images obtained. Through participation, a whole range of experiences will include: (1) mission planning; (2) research and pilot projects to train teams; (3) identification and recruitment of scientific mentors and dialogue; (4) selection of a student advisory team to be available during the mission; (5) analysis of data and compilation of findings; (6) report preparation, constucted along sound scientific principles; and (7) presentation and defense of findings before a meeting of competitive student groups and scientist in the field

The objective of this study was to determine the a) sense of ‘presence’ (the feeling of being in a scene) experienced in two food related VR scenes b) capture information regarding the participants experiences in VR

Challenges to monitoring groundwater contaminants in riparian and terrestrial vegetation

In recent years, there have been improvements to environmental monitoring approaches for large scale industrial activities including mining. Efforts have focused on developing scientifically rigorous, defensible objectives and guidelines for surface water, waste, air and sediment monitoring. However, the development of guidelines for monitoring impacts on vegetation has lagged compared to other programs. We review the challenges and opportunities around designing strategies for effective monitoring and detecting of sub-lethal change in vegetation communities as a result of groundwater impacts. Mining influences on vegetation are multi-fold. A primary mechanism, however, is through changes in groundwater quantity and/or quality. Both terrestrial and riparian communities can be impacted by changes in groundwater levels by dewatering/extraction activities, impoundments and, changes in groundwater quality through leaching of contaminants into shallow groundwater. These physical and chemical changes to groundwater can have major influences on groundwater dependent vegetation communities leading to altered community composition, structure and health. Whilst there are a range of methodologies that measure baseline vegetation community structure there is little in the way of standardised methodologies designed to detect the chronic or sub-lethal impacts of groundwater change and/or groundwater contaminants. Furthermore many of these impacts are often set against a background of historical legacy mining impacts, other land uses and high climatic variability. Identifying causal linkages between mining activity and vegetation change can present considerable challenges

Multipurpose Cargo Transfer Bag

The Logistics Reduction (LR) project within the Advanced Exploration Systems (AES) program is tasked with reducing logistical mass and repurposing logistical items. Multipurpose Cargo Transfer Bags (MCTB) have been designed such that they can serve the same purpose as a Cargo Transfer Bag, the suitcase-shaped common logistics carrying bag for Shuttle and the International Space Station. After use as a cargo carrier, a regular CTB becomes trash, whereas the MCTB can be unzipped, unsnapped, and unfolded to be reused. Reuse ideas that have been investigated include partitions, crew quarters, solar radiation storm shelters, acoustic blankets, and forward osmosis water processing
