Investigation Of Spatial Filtering For Planar Range-Resolved Pulsed Laser Ablated Plume Imaging, James F. Winslow

USF Tampa Graduate Theses and Dissertations

This thesis presents a study of the intensified charge-coupled device (ICCD) imaging of pulsed laser ablated plumes. Two-dimensional imaging of laser ablated plumes is a very important diagnostic for PLD. ICCD array photography is a useful tool for imaging PLD. The images obtained using the standard technique are characterized and compared with ICCD images of an altered plume, ICCD images intentionally violating standard imaging procedures, and film thickness. The depth resolving properties of a pinhole was investigated with the intention of applying it to PLD plume imaging. This results in a more thorough understanding of the depth resolving property of …

Social And Behavioral Aspect Of Mother’S Health Behaviors And Neonatal Health: Risk Factor Analysis Of Neonatal Septicemia In Urban Slums Of Muntinlupa, Philippines, Chisaki Sato

USF Tampa Graduate Theses and Dissertations

Reducing neonatal mortality can contribute to the further reduction of infant mortality rates in international health as it is responsible for about half of the mortality rate for those underfive today. The situation of infant mortality in the Philippines is no exception to this global trend. This study of the social demographic aspects of sepsis neonatorum in the Philippines has explored the conditions of the urban environment, and local cultures related to newborn illnesses and the patterns of health seeking behaviors of urban poor mothers which can affect the survival of newborns. The mix of qualitative and quantitative research methods …

The Distribution Of Radon Concentration In Caves, Arrigo A. Cigna

International Journal of Speleology

Radon concentration in caves is known to vary within an extremely wide range. Here the distribution of the average values of radon concentration is examined and a power law describing is identified, i.e. radon concentration has a fractal dimension D=1.26. This fact means that concentrations are not grouped around a mean value, a characteristic common to many other phenomena.

Influence Of Solar Luminosity Over Geomagnetic And Climatic Cycles As Derived From Speleothems, Y. Shopov, D. Stoykova, L. Tsankov, M. Sanabria, D. Georgieva, D. Ford, L. Georgiev

International Journal of Speleology

We observed cycles presented in a luminescent solar insolation proxy record from a speleothem from Jewel Cave, South Dakota, US. We found cycles of orbital precession with periods of 23 and 19 ka and of obliquity of 41 ka and many others from non-orbital origin in this sample. We determined the Solar origin of the cycles with durations of 11500, 4400, 3950, 2770, 2500, 2090, 1960, 1670, 1460, 1280, 1195, 1145, 1034, 935, 835, 750 and 610 years. It was done by their detection both in proxy records of speleothem luminescence, Δ¹⁴C and the intensity of the geomagnetic …

Paleocollapse Structures As Geological Record For Reconstruction Of Past Karst Processes During The Upper Miocene Of Mallorca Island, P. A. Robledo Ardila, J. J. Durán, L. Pomar

International Journal of Speleology

Paleocollapse structures and collapse breccias are one of the major features for paleokarst analysis and paleoclimate record. These are affecting the Llucmajor and Santanyí carbonate platforms. These platforms, of southern and eastern Mallorca respectively, are a good example of progradation reef platform in the western Mediterranean. The Santanyí platform is constituted of two sedimentary units, both affected by paleocollapse structures: (1) The Reef Complex attributed to the upper Tortonian-lower Messinian; (2) Santanyí Limestone attributed to the Messinian. There are abundant paleocollapse outcropping in the Reef Complex and Santanyí Limestone units. These structures have been produced by roof collapse of caverns …

It discusses Activators of Luminescence in Speleothems as a source of major mistakes in the interpretation of luminescent paleoclimatic records. It demonstrates the existence of 6 types of luminescence of speleothems and cave minerals in dependence of the type of the luminescence center and its incorporation in the mineral. 24 different activators of photoluminescence of speleothem calcite and 11 of aragonite …

Surface Cover Infiltration Index: A Suggested Method To Assess Infiltration Capacity For Intrinsic Vulnerability In Karstic Areas In Absence Of Quantitative Data, Levent Tezcan, Mehmet Ekmekci

International Journal of Speleology

Karst is a hydrogeological environment of importance not only for its water resources potential but also for its scenic and economic potential, thereby increasing the intensity of human impact. The uniqueness of karst in this regard stems from its high sensitivity and vulnerability to imposed pressures and its distinctive response to these pressures. Therefore, a clear definition and formulation of the concept of ‘intrinsic vulnerability’ is essential for the design of vulnerability and/or management criteria of the karstic system as a resource. In this regard, the recharge rate, the amount of water passing through the unsaturated zone into the aquifer, …

Evolution Of Golpazari-Huyuk Karst System (Bilecik-Turkey): Indications Of Morpho-Tectonic Controls, Mehmet Ekmekci, Lütfü Nazik

International Journal of Speleology

The Golpazari-Huyuk karst system is located in the Central Sakarya Basin whose geomorphologic evolution is mainly controlled by the Post-Miocene epirogenic continental rise. Drastic change in the drainage pattern and dissection of the carbonate platform were the major consequences of this tectonic movement. Rapid incision of the Sakarya river changed the position of the erosion base which consequently distorted the direction of surface and subsurface flow. The Golpazari and Huyuk plains are two topographically distinct, flat bottomed geomorphic features separated by a carbonate rock relief. The difference in elevation between these 10 km distant plains is 350 m. Morphological, geological …

Dissaggregation Modelling Of Spring Discharges, Elena Kirilova Bojilova

International Journal of Speleology

Disaggregation models are basically divided into three main groups: temporal, spatial and temporal-spatial. The focus of this paper is the application of temporal disaggregation models to disaggregate the seasonal flow in some large time intervals to sub-seasonal flows in some shorter time intervals. Two basic models are applied: the original model of Mejia and Rousselle and the corrected extended Lin model one-stage disaggregation. The flow totals from some karstic springs are used. Data for five springs in different areas of Bulgaria for the aims of the study are executed. The synthetic data generation for the chosen spring stations for a …

Comparative Estimate Of Resistance To Drought For Selected Karstic Aquifers In Bulgaria, Tatiana Orehova

International Journal of Speleology

Effective management of water resources requires adequate knowledge of groundwater system including the influence of climate variability and climate change. The drought of 1982-1994 in Bulgaria has led to important decrease of springflow and lowering of water levels. Therefore, groundwater demonstrated its vulnerability to drought. The purpose of this paper is to determine relative resistance of selected aquifers in Bulgaria to a prolonged decrease of recharge to groundwater. The drought resistance indicator has been defined for some karstic aquifers based on the method proposed in report of BRGM. The data from National Hydrogeological Network located in the National Institute of …

Trace Elements In Speleothems. A Short Review Of The State Of The Art, Sophie Verheyden

International Journal of Speleology

A state of the art of the research on trace elements of speleothems is given. First studies focussed on problems such as the colour of speleothems and the aragonite problem. Insitu studies and studies oriented towards a better understanding of vadose hydrology brought new insights in the controls on trace elemental composition of speleothems. Recent studies deal with microscale analyses and annual and intra-annual chemistry changes. Further in-situ studies should be performed to further differentiate influences, such as climate, soil/weathering and local hydrology in order to better constrain possible transfer functions between the surface and a speleothem.

Cave Temperatures And Global Climatic Change, Giovanni Badino

International Journal of Speleology

The physical processes that establish the cave temperature are briefly discussed, showing that cave temperature is generally strictly connected with the external climate. The Global Climatic changes can then influence also the underground climate. It is shown that the mountain thermal inertia causes a delay between the two climates and then a thermal unbalance between the cave and the atmosphere. As a consequence there is a net energy flux from the atmosphere to the mountain, larger than the geothermal one, which is deposited mainly in the epidermal parts of caves.

The Role Of The Environmental Archaeologist In The Study And Reconstruction Of Cave Palaeoclimate, Maria Gkioni

International Journal of Speleology

Man and environment are engaged in a continuous battle to impose themselves on one another. The results are found in environmental modifications or climatic oscillations and, as far as man is concerned, in the different character of cultural remains. Man responds to environmental changes by migrating or evolving technological innovations, both of which leave important remains that the archaeologist is called on to recognise and interpret during and after an excavation. They both also reflect the sociocultural responses to climatic stress. This paper refers to a specific case study, caves, which housed man and his activities from the very early …

Architectural Registration And It's Diversity Vortex., Shannon Chance

Articles

Architects: take a serious look at your demographics. While other professions are making strides to represent the diversity of America's population, yours lags markedly behind. Most U.S. architecture schools began admitting women and minorities between 1965 and 1972, but many who completed architecture degrees in the interim haven't yet received professional licensure. The ranks of licensed architects remain mainly white and mainly male, which denies society fair representation in shaping the built environment. Consider that African-American females comprise roughly 7% of the U.S. population but less than 0.2% of licensed architects; they've achieved proportionally higher success in law, medicine, and …

Property Rights And Intrabrand Restraints, Alan J. Meese

Faculty Publications

Intrabrand restraints limit the discretion of one or more sellers-usually dealers-with respect to the disposition of a product sold under a single brand. While most scholars believe that such contracts can help assure optimal promotion of a manufacturer's products, there is disagreement about the exact manner in which such restraints accomplish this objective. Many scholars believe that such restraints themselves induce dealers to engage in promotional activities desired by the manufacturer. Others believe that such restraints merely serve as "performance bonds," which dealers will forfeit if they fail to follow the manufacturer's precise promotional instructions. Some scholars reject both approaches, …
