The Lamps That Lit Their Way, Rick Olson

Mammoth Cave Research Symposia

The distinctive lanterns used at Mammoth Cave from the middle 1800s until 1938 appear to be a locally derived design. Early whale oil railroad lanterns share some characteristics of the Mammoth Cave lanterns, but L&N Railroad lanterns do not appear to have influenced the design. At this time, the design pathway appears to lead from simple open-flame tin candle lanterns to the same lantern with a petticoat lamp affixed in place of the candle, and then finally to the font or oil container being soldered onto the lamp base as one unit. This basic Mammoth Cave lantern varied somewhat over …

The Puzzling Mr. Janin And Mammoth Cave Management, 1900-1910, Katie Algeo

Mammoth Cave Research Symposia

Albert Covington Janin was the key architect of tourism development at Mammoth Cave for two decades at the start of the twentieth century, yet little has been written about his tenure. This paper explores his background and accomplishments for the period 1900 to 1910 as an initial attempt to understand his contributions to Mammoth Cave. Material about his activities in relation to Mammoth Cave is synthesized from primary sources in the archival collections of the Huntington Library (HL) of San Marino, California, and the Historical Society of Washington, DC (HSW).

Mapping Of Mammoth Cave: How Cartography Fueled Discoveries, With Emphasis On Max Kaemper’S 1908 Map, Roger W. Brucker

Mammoth Cave Research Symposia

Maps came first at Mammoth Cave, Kentucky. Then came explorers who used the maps to make discoveries as they gained a more comprehensive understanding of the longest cave in the world. The saga of mapping at Mammoth Cave parallels the mapping of North America from the 1600s onward. The first map was an “Eye-Draught Map of Mammoth Cave”, penned from memory in 1811, not a survey, to acquaint merchants with the location of saltpeter dirt. In 1835 the managers of Mammoth Cave hired a surveyor, Edmond Lee, to survey and map and profile the main cave passages. Stephen Bishop, a …

Max Kaemper’S Unique Selection Of Place Names For His 1908 Map Of Mammoth Cave, Charles A. Swedlund, George M. Crothers

Mammoth Cave Research Symposia

In this paper we present Max Kaemper’s unique selection of Place Names for his 1908 map of Mammoth Cave. He realized the importance of Place Names and they became a feature on his map. His sensitive selection of Place Names provides a greater cultural emphasis, when compared to the previous maps.

The Evolution Of Cave Mapping And Cartography, Pat Kambesis

Mammoth Cave Research Symposia

“Does it go?” Is the initial question that has inspired many a cave explorer to push the extent of a cave system. But the answer only brings more questions…how far, how long, how deep does it go? During the exploration process, as a cave system reveals its complexity, the questions also change – what is the cave’s relationship to the surface, and to surrounding caves? What are the features and obstacles that the cave contains? Those involved in cave exploration know that the only way to answer these questions is with systematic documentation in the form of cave and surface …

Enrichment Of Surface-Active Compounds In Coalescing Cloud Drops, Ilya Taraniuk, Alexander Kostinski, Yinon Rudich

Department of Physics Publications

Surfactants often found in tropospheric aerosols, can affect the onset and development of clouds. Due to high dilution during droplet growth, the effects of surfactants on cloud microphysical processes have been mostly neglected. However, while cloud growth by coalescence conserves the combined volume of all cloud droplets, it reduces the combined surface area. This could lead to enrichment of water‐insoluble surfactants (WIS) and to reduced surface tension of droplets forming in warm processes. Measurements of individual raindrops reveal the presence of water insoluble surfactants. Our field and laboratory studies as well as simple theoretical arguments suggest that by causing varying …

Comparative Genomics Of Geobacter Chemotaxis Genes Reveals Diverse Signaling Function, Hoa T. Tran, Julia Krushkal, Frances M. Antommattei, Derek R. Lovley, Robert Weis

Robert Weis

Background Geobacter species are δ-Proteobacteria and are often the predominant species in a variety of sedimentary environments where Fe(III) reduction is important. Their ability to remediate contaminated environments and produce electricity makes them attractive for further study. Cell motility, biofilm formation, and type IV pili all appear important for the growth of Geobacter in changing environments and for electricity production. Recent studies in other bacteria have demonstrated that signaling pathways homologous to the paradigm established for Escherichia coli chemotaxis can regulate type IV pili-dependent motility, the synthesis of flagella and type IV pili, the production of extracellular matrix material, and …

Hybridization Among Three Native North American Canis Species In A Region Of Natural Sympatry, Frank Hailer, Jennifer A. Leonard

Rocky Mountain Wolf Recovery: Annual Reports

Background: Population densities of many species throughout the world are changing due to direct persecution as well as anthropogenic habitat modification. These changes may induce or increase the frequency of hybridization among taxa. If extensive, hybridization can threaten the genetic integrity or survival of endangered species. Three native species of the genus Canis, coyote (C. latrans), Mexican wolf (C. lupus baileyi) and red wolf (C. rufus), were historically sympatric in Texas, United States. Human impacts caused the latter two to go extinct in the wild, although they survived in captive breeding programs. Morphological data demonstrate historic reproductive isolation between all …

Theoretical Top Quark Cross Section At The Fermilab Tevatron And The Cern Lhc, Nikolaos Kidonakis, Ramona Vogt

Faculty Articles

We present results for the top quark pair cross section at the Tevatron and the LHC. We use the resummed double differential cross section, employing the fully kinematics-dependent soft-anomalous-dimension matrices, to calculate the soft-gluon contributions at next-to-next-to-leading order (NNLO). We improve and update our previous estimates by refining our methods, including further subleading terms, and employing the most recent parton distribution function sets. The NNLO soft corrections significantly enhance the NLO cross section while considerably reducing the scale dependence. We provide a detailed discussion of all theoretical uncertainties in our calculation, including kinematics, scale, and parton distribution uncertainties, and clarify …

Photoproduction of beauty quarks in events with two jets and an electron associated with one of the jets has been studied with the ZEUS detector at HERA using an integrated luminosity of 120pb-1. The fractions of events containing b quarks, and also of events containing c quarks, were extracted from a likelihood fit using variables sensitive to electron identification as well as to semileptonic decays. Total and differential cross sections for beauty and charm production were measured and compared with next-to-leading-order QCD calculations and MonteCarlo models. © 2008 The American Physical Society.

Analysis Of Chromium And Nickel In Soil And Plant Tissue Collected From The Experimental Vineyard At California Polytechnic State University, San Luis Obispo, Ca, Ian Leslie, Chip Appel, Craig Stubler, Kiana Amiri-Davani, Ashley Devalentine, Jose Gomez, Daniel Kim, Tommy Konwinski, Angie Quintana-Jones, Keith Patterson

Earth and Soil Sciences

Serpentinitic soils often contain high concentrations of heavy metals, including chromium (Cr) and nickel (Ni). Soils derived from serpentine parent material are used for agricultural purposes throughout San Luis Obispo County, CA. This study was undertaken to determine the amount of total and bioaccessible Cr and Ni in soil and vine tissue from a vineyard planted on soils derived from serpentine geology. Eighteen soil and plant samples were collected from different slope position and vine types (syrah and chardonnay). Soil samples were collected from about 0 to 30 cm at the base of the vines and 15 to 20 leaf …

Contributions To Khovanov Homology, Stephan M. Wehrli

Mathematics - All Scholarship

Khovanov homology ist a new link invariant, discovered by M. Khovanov, and used by J. Rasmussen to give a combinatorial proof of the Milnor conjecture. In this thesis, we give examples of mutant links with different Khovanov homology. We prove that Khovanov's chain complex retracts to a subcomplex, whose generators are related to spanning trees of the Tait graph, and we exploit this result to investigate the structure of Khovanov homology for alternating knots. Further, we extend Rasmussen's invariant to links. Finally, we generalize Khovanov's categorifications of the colored Jones polynomial, and study conditions under which our categorifications are functorial …

Development And Annotation Of Perennial Triticeae Ests And Ssr Markers., B.S. Bushman, S R Larson, I W Mott, P F Cliften, R R Wang, N J Chatterton, A G Hernandez, S Ali, R W Kim, Jyothi Thimmapuram, G Gong, L Liu, M A Mikel

Cyber Center Publications

Triticeae contains hundreds of species of both annual and perennial types. Although substantial genomic tools are available for annual Triticeae cereals such as wheat and barley, the perennial Triticeae lack sufficient genomic resources for genetic mapping or diversity research. To increase the amount of sequence information available in the perennial Triticeae, three expressed sequence tag (EST) libraries were developed and annotated for Pseudoroegneria spicata, a mixture of both Elymus wawawaiensis and E. lanceolatus, and a Leymus cinereus x L. triticoides interspecific hybrid. The ESTs were combined into unigene sets of 8 780 unigenes for P. spicata, 11 281 unigenes for …

An Investigation Of The Security Designs Of A Structured Query Language (Sql) Database And Its Middleware Application And Their Secure Implementation Within Thinclient Environments, Melissa D. Winner-Leoni

Regis University Student Publications (comprehensive collection)

The Information Portability and Accountability Act (HIPAA) and The SarbanesOxley (SOX) regulations greatly influenced the health care industry regarding the means of securing financial and private data within information and technology. With the introduction of thinclient technologies into medical information systems (IS), data security and regulation compliancy becomes more problematic due to the exposure to the World Wide Web (WWW) and malicious activity. This author explores the best practices of the medical industry and information technology industry for securing electronic data within the thinclient environment at the three levels of architecture: the SQL database, its middleware application, and Web interface. …

Simple Inhibitors Of Histone Deacetylase Activity That Combine Features Of Short-Chain Fatty Acid And Hydroxamic Acid Inhibitors, Jessica L. Tischler, Basel Abuaita, Sierra C. Cuthpert, Christopher Fage, Kristi Murphy, Andrew Saxe, Edward B. Furr, Jamie Hedrick, Jennifer Meyers, David Snare, Ali R. Zand

Chemistry & Biochemistry Publications

Butyric acid and trichostatin A (TSA) are anti-cancer compounds that cause the upregulation of genes involved in differentiation and cell cycle regulation by inhibiting histone deacetylase (HDAC) activity. In this study we have synthesized and evaluated compounds that combine the bioavailability of short-chain fatty acids, like butyric acid, with the bidentate binding ability of TSA. A series of analogs were made to examine the effects of chain length, simple aromatic cap groups, and substituted hydroxamates on the compounds' ability to inhibit rat-liver HDAC using a fluorometric assay. In keeping with previous structure-activity relationships, the most effective inhibitors consisted of longer …

Spectra Of Nearby Galaxies Measured With A New Very Broadband Receiver, Gopal Narayanan, Ronald L. Snell, Neal A. Erickson, Aeree Chung, Mark H. Heyer, Min Yun, William M. Irvine

William M. Irvine

Three-millimeter-wavelength spectra of a number of nearby galaxies have been obtained at the Five College Radio Astronomy Observatory (FCRAO) using a new, very broadband receiver. This instrument, which we call the Redshift Search Receiver, has an instantaneous bandwidth of 36 GHz and operates from 74 to 110.5 GHz. The receiver has been built at UMass/FCRAO to be part of the initial instrumentation for the Large Millimeter Telescope (LMT) and is intended primarily for determination of the redshift of distant, dust-obscured galaxies. It is being tested on the FCRAO 14 m by measuring the 3 mm spectra of a number of …
