Evaluation Of First Order Error Induced By Conservative-Tracer Temperature Approximation For Mixing In Karstic Flow, Philippe Machetel, David A. Yuen

Sinkhole Conference 2015

Fluid dynamics in karst systems is complex due to the heterogeneity of hydraulic networks that combine the Porous Fractured Matrix (PFM) and the interconnected drains (CS). These complex dynamic systems often need to be treated as “black boxes” in which only input and output properties are known. In this work, we propose to assess the first-order error induced by considering the temperature as a conservative tracer for flows mixing in karst (fluvio-karst). The fluvio-karstic system is treated as an open thermodynamic system (OTS), which exchanges water and heat with its surrounding. We propose to use a cylindrical PFM drained by …

Study On Monitoring And Early Warning Of Karst Collapse Based On Botdr Technique, Zhende Guan

Sinkhole Conference 2015

Brilliouin Optical Time Domain Reflectometer (BOTDR) is a newly developed measurement and monitoring technique, which utilizes Brilliouin spectroscopy and Optical Time Domain Reflectometer (Jiang et al., 2006; Zhang et al., 2009; Xu et al.,2011) to measure strain generated in optical fibers as distributed in the longitudinal direction. This paper introduces the principle and characters of BOTDR technique firstly, and makes an example of karst collapse monitoring at section K14 of highway from Guilin to Yangshuo. And we talk about how to use this technique in underlying karst collapse monitoring in karst highway, discuss environmental factors, like temperature and vehicle dynamic …

With the common goal of more accurately and consistently quantifying ambient concentrations of free metal ions and natural organic ligands in aquatic ecosystems, researchers from 15 laboratories that routinely analyze trace metal speciation participated in an intercomparison of statistical methods used to model their most common type of experimental dataset, the complexometric titration. All were asked to apply statistical techniques that they were familiar with to model synthetic titration data that are typical of those obtained by applying state-of-the-art electrochemical methods – anodic stripping voltammetry (ASV) and competitive ligand equilibration-adsorptive cathodic stripping voltammetry (CLE-ACSV) – to the analysis of natural …

A Milk And Ochre Paint Mixture Used 49,000 Years Ago At Sibudu, South Africa, Paola Villa, Luca Pollarolo, Ilaria Degano

KIP Articles

Gas chromatography/mass spectrometry, proteomic and scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM/EDS) analyses of residue on a stone flake from a 49,000 year-old layer of Sibudu (South Africa) indicate a mixture of ochre and casein from milk, likely obtained by killing a lactating wild bovid. Ochre powder production and use are documented in Middle Stone Age South African sites but until now there has been no evidence of the use of milk as a binder. Our analyses show that this ochre-based mixture was neither a hafting adhesive nor a residue left after treating animal skins, but a liquid mixture …

Landscape Legacies Of Sugarcane Monoculture At Betty's Hope Plantation, Antigua, West Indies, Suzanna M. Pratt

USF Tampa Graduate Theses and Dissertations

Sugarcane cultivation has played a key role in the development of the Caribbean since the seventeenth century A.D. The Eastern Caribbean island of Antigua in the West Indies was almost exclusively dedicated to sugarcane monoculture from the mid-1600s until its independence from Britain in 1981. This research seeks to better understand the landscape legacies left by long-term sugarcane monoculture at the site of Betty's Hope Plantation in Antigua. This study creates a 400-year simulation of crop yields using the USDA's Erosion Productivity Impact Calculator (EPIC), and evaluates the simulated trajectory of landscape change using historical information about the plantation's agricultural …

Terrestrial Lidar-Based Automated Counting Of Swiftlet Nests In The Caves Of Gomantong, Sabah, Borneo., Donald A. Mcfarlane, Warren Roberts, Manfred Buchroithner, Guy Van Rentergem, Joyce Lundberg, Stefan Hautz

International Journal of Speleology

High resolution terrestrial laser scanning (TLS) within the Simud Hitam cave, Gomantong, has proven successful at discriminating the nests of black-nest swiftlets from roosting bats in high, inaccessible locations. TLS data was imported into ArcGIS software, allowing for semi-automated counting of nests. Spatial analysis of nest locations has established a maximum packing density of 268 nests/m² in optimum locations, which correspond to roof slopes of >20 degrees. Rhinolophid bats roost adjacent to, but not within nest locations, preferring roof surfaces close to horizontal.

Ocean Currents Generate Large Footprints In Marine Palaeoclimate Proxies, Erik Van Sebille, Paolo Scussolini, Jonathan V. Durgadoo, Frank J. C. Peeters, Arne Biastoch, Wilbert Weijer, Chris Turney, Claire B. Paris, Rainer Zahn

C-IMAGE Publications

Fossils of marine microorganisms such as planktic foraminifera are among the cornerstones of palaeoclimatological studies. It is often assumed that the proxies derived from their shells represent ocean conditions above the location where they were deposited. Planktic foraminifera, however, are carried by ocean currents and, depending on the life traits of the species, potentially incorporate distant ocean conditions. Here we use high-resolution ocean models to assess the footprint of planktic foraminifera and validate our method with proxy analyses from two locations. Results show that foraminifera, and thus recorded palaeoclimatic conditions, may originate from areas up to several thousands of kilometres …

Potential Habitat Of Acropora Spp. On Reefs Of Florida, Puerto Rico, And The Us Virgin Islands, Katherine Wirt

Marine Science Faculty Publications

Elkhorn and staghorn corals (Acropora palmata, Acropora cervicornis) were listed in 2006 as threatened under the Endangered Species Act. The goal of this study was to create model potential-habitat maps for A. palmata and A. cervicornis, while identifying areas for possible re-establishment. These maps were created using a database of reported field observations in combination with existing benthic habitat maps. The mapped coral reef and hardbottom classifications throughout Florida, Puerto Rico, and the US Virgin Island reef tracts were used to generate potential-habitat polygons using buffers that incorporated 95% and 99% of reported observations of Acropora spp. …

A Black Deer At Black Cave: New Pictograph Radiocarbon Date For The Lower Pecos, Texas, Lennon Bates, Amanda Castañeda, Carolyn Boyd, Karen Steelman

KIP Articles

A Pecos River style painting of a black deer from Black Cave Annex (41VV76a) in southwest Texas was radiocarbon dated. Using plasma oxidation and accelerator mass spectrometry, we obtained an age of 1465 ± 40 RCYBP (2 sigma calibrated age range of A.D. 470-660). This age is younger than the accepted age range for Pecos River style paintings, which is approximately 4000-3000 years B.P. This new measurement in association with other younger dates prompts us to question whether the Pecos River style endured for a longer time period than previously thought. More radiocarbon research is needed in order to understand …

Schreibersite: Synthesis, Characterization And Corrosion And Possible Implications For Origin Of Life, Nikita Latesha La Cruz

USF Tampa Graduate Theses and Dissertations

We present study of the synthesis and reactions of an analog of the meteoritic mineral schreibersite with formula (Fe,Ni)3P, believed to be a prebiotic source of reactive phosphorus that may have prompted the formation of phosphorylated biomolecules near the time of the origin of life (Pasek and Lauretta, 2005). The mineral was synthesized by mixing stoichiometric proportions of elemental iron, nickel and phosphorus and heating in a tube furnace at 820°C for approximately 235 hours under argon or under vacuum, a modification of the method of Skála and Drábek (2002). The mineral was characterized using X-ray diffractometry (XRD), X-ray photoelectron …

Speleoclimate Dynamics In Santana Cave (Petar, São Paulo State, Brazil): General Characterization And Implications For Tourist Management, Heros Augusto Santos Lobo, Paulo Cesar Boggiani, José Alexandre De Jesus Perinotto

International Journal of Speleology

Show caves provide tourists with the opportunity to have close contact with natural underground spaces. However, visitation to these places also creates a need for management measures, mainly the definition of tourist carrying capacity. The present work describes the results of climate monitoring and atmospheric profiling performed in Santana Cave (Alto Ribeira State and Tourist Park – PETAR, Brazil) between 2008 and 2011. Based on the results, distinct preliminary zones with different levels of thermal variation were identified, which classify Santana Cave as a warm trap. Two critical points along the tourist route (Cristo and Encontro Halls) were identified where …

Landscape Evolution Of Menikio Mountain (Macedonia, Greece) Based On Morphological And Sedimentological Analyses Of Caves, Christos Pennos

KIP Articles

The present study examines the landscape evolution of the Menikio Mountain based on morphological features that are evident inside the caves. The various evolutionary stages of the Mountain's landscape development are dated. In addition, a paleoclimatic reconstruction for the broader area is attempted. For this approach two stalagmites have been selected from the Mikro and Megalo Eptamilon caves. U - series dating techniques were used in order to determine the exact time spam of the records and in order to obtain the paleoclimatic signal, measurements of δ18O and δ13C were performed along the growth axis of the stalagmites. The project …

Commuter Mode Choice And Free Car Parking, Public Transportation Benefits, Showers/Lockers, And Bike Parking At Work: Evidence From The Washington, Dc Region, Andrea Hamre, Ralph Buehler

Journal of Public Transportation

Municipalities and employers in the U.S. attempt to reduce commuting by automobile through commuter benefits for riding public transportation, walking, or cycling. Many employers provide a combination of benefits, often including free car parking alongside benefits for public transportation, walking, and cycling. This study evaluates the relationship between commuter benefits and mode choice for the commute to work using revealed preference data on 4,630 regular commuters, including information about free car parking, public transportation benefits, showers/lockers, and bike parking at work in the Washington, DC region. Multinomial logistic regression results show that free car parking at work is related to …

Solvent Dependent Molecular Mechanics: A Case Study Using Type I Collagen, Heather Harper

USF Tampa Graduate Theses and Dissertations

Being the most abundant protein in the body, by mass, type I collagen provides the building blocks for tissues such as bone, extra-cellular matrix, tendons, cornea, etc[1-3]. The ability of a single protein to create structures with such various mechanical properties is not fully understood. Before one can engineer and assemble a complex tissue, such as cornea, the mechanisms underlying the formation and assembly, mechanical properties, and structure must be investigated and quantified. The work presented herein contains an extensive study of Type I collagen from the molecular to the tissue level.

The engineering of collagenous tissues that mimic the …

Women In Ecotourism, April 2014, Emily Doherty

Monteverde Institute: Culture, Community, and Health

Ecotourism is one of Costa Rica's main industries, and while it brings huge economic capital into the country, these new opportunities are not equally distributed among all genders. Women are slowly gaining social equality, but currently women are limited by only getting specific domestic jobs in the ecotourism industry. Many argue that ecotourism in Monteverde is empowering women and it is true that more women are getting jobs outside the home, however, they are generally still confined to domestic types of jobs like cleanin and cooking. A survey of 12 businesses in Monteverde revealed that out of 22 outdoor educational …

Horse Power, April 2014, Jesseka Mcgee, Roberta Duarte

Monteverde Institute: Culture, Community, and Health

Horses pass through Monteverde every day, and while they are mostly for tourists, a few country folk still ride them around town. They are almost unknown across Monteverde these days; they are rare enough that children point and wave when a horse goes by. When we mentioned the possibility of using horses for a sustainable future in Monteverde, collegues and a few community members tended to burst into...well, horse laughter. That will never be necessary, they told us - we will just use bio-fuels as easily as we do petrol now, or create something new. This project proposes to offer …

Assessing The Impact Of Untreated Sewage On The Coral Reef System Off The Coast Of Caye Caulker, Belize: Applying The Foram Index, Kristen Lynn Emrich

USF St. Petersburg campus Master's Theses (Graduate)

Human raw sewage pollution is one of several environmental concerns in coastal waters of Belize. This study utilizes foraminiferal assemblage distribution in combination with fecal sterols to determine the presence of human sewage and its effects on a coral reef system off the coast of Caye Caulker-Belize. A total of 125 sediment samples were collected off the coast of Caye Caulker. Fecal sterol concentrations (coprostanol), grain analysis (mud percent), foraminiferal ecological indices (species richness, density, and diversity), foraminiferal assemblages, and the FORAM Index (FI) were assessed. Coprostanol analysis showed higher concentrations nearest the eastern shore of Caye Caulker, with lower …

Nonexistent Compounds As A Guide To Innovation, Dean F. Martin, Barbara B. Martin

Chemistry Faculty Publications

A study of nonexistent compounds can be a useful exercise in gaining insight into the factors that can inhibit innovation. Several reasons are suggested: lack of financial support, disinterest in preparing compounds that lack evident utility, notable synthetic challenges with inadequate rewards, inhibition by well-established contemporary knowledge, and invalid interpolations.

Study Of Filled Dolines By Using 3d Stereo Image Processing And Electrical Resistivity Imaging, Mateja Breg Valjavec

International Journal of Speleology

This article deals with doline degradation due to uncontrolled waste dumping in the past in the Logatec Polje in Slovenia. It introduces a concept for determining 3D geometric characteristics (shape, depth, radius, area, and volume) of formerly concave landforms (i.e., recently filled dolines) by using a combination of two methods: (1) photogrammetric stereo processing of archival aerial photographs and (2) electrical resistivity imaging (ERI). To represent, visualize, and study the characteristics of the former surface morphology (i.e., the dolines before they were filled), a digital terrain model (DTM) for 1972 (DTM1972) was made using digital photogrammetry processing of five sequential …
