Creator:: Garrison, V. H., Majewski, M. S., Foreman, W. T., Genualdi, S. A., Mohammed, A., and Simonich, S. L. Massey
Abstract:: Anthropogenic semivolatile organic compounds (SOCs) that persist in the environment, bioaccumulate, are toxic at low concentrations, and undergo long-range atmospheric transport (LRT) were identified and quantified in the atmosphere of a Saharan dust source region (Mali) and during Saharan dust incursions at downwind sites in the eastern Caribbean (U.S. Virgin...

Occurrence and sources of natural and anthropogenic lipid tracers in surface soils from arid urban areas of Saudi Arabia

Creator:: Rushdi, Ahmed I., Al-Mutlaq, Khalid F., El-Mubarak, Aarif H., Al-Saleh, Mohammed A., El-Otaibi, Mubarak T., Ibrahim, Sami M. M., and Simoneit, Bernd R. T.
Abstract:: Soil particles contain a variety of natural and anthropogenic organic components, and in urban areas can be considered as local collectors of pollutants. Surface soil samples were taken from ten urban areas in Riyadh during early winter of 2007. They were extracted with dichloromethane-methanol mixture and the extracts were analyzed...

Enrichments of Metals, Including Methylmercury, in Sewage Spills in South Carolina, USA

Creator:: Emmons, Alison M., Bizimis, Michael, Lang, Susan Q., Stangler, William, Geidel, Gwendelyn, Baalousha, Mohammed, Wanamaker, Emma, and Rothenberg, Sarah E.
Abstract:: Exposure to microbial pathogens is the primary concern of sanitary sewer overflows; however, sewage spills may also be a significant source of toxic metals, including methylmercury (MeHg). Between November 2015 and January 2017, after Hurricane Joaquin, surface water samples were collected routinely from three creeks in Columbia, SC. Routine sampling...

Heat flow in the Lesser Antilles island arc and adjacent back arc Grenada basin

Creator:: Manga, Michael, Hornbach, Matthew J., Le Friant, Anne, Ishizuka, Osamu, Stroncik, Nicole, Adachi, Tatsuya, Aljahdali, Mohammed, Boudon, Georges, Breitkreuz, Christoph, Fraass, Andrew, Fujinawa, Akihiko, Hatfield, Robert, Jutzeler, Martin, Kataoka, Kyoko, Lafuerza, Sara, Maeno, Fukashi, Martinez-Colon, Michael, McCanta, Molly, Morgan, Sally, Palmer, Martin R., Saito, Takeshi, Slagle, Angela, Stinton, Adam J., Subramanyam, K. S. V., Tamura, Yoshihiko, Talling, Peter J., Villemant, Benoit, Wall-Palmer, Deborah, and Wang, Fei
Abstract:: Using temperature gradients measured in 10 holes at 6 sites, we generate the first high fidelity heat flow measurements from Integrated Ocean Drilling Program drill holes across the northern and central Lesser Antilles arc and back arc Grenada basin. The implied heat flow, after correcting for bathymetry and sedimentation effects,...

Permeability and pressure measurements in Lesser Antilles submarine slides: Evidence for pressure-driven slow-slip failure

Creator:: Hornbach, Matthew J., Manga, Michael, Genecov, Michael, Valdez, Robert, Miller, Peter, Saffer, Demian, Adelstein, Esther, Lafuerza, Sara, Adachi, Tatsuya, Breitkreuz, Christoph, Jutzeler, Martin, Le Friant, Anne, Ishizuka, Osamu, Morgan, Sally, Slagle, Angela, Tailing, Peter J., Fraass, Andrew, Watt, Sebastian F.

S. V., Tamura, Yoshihiko, Villemant, Benoît, Wall-Palmer, Deborah, and Wang, Fei
Abstract:: Recent studies hypothesize that some submarine slides fail via pressure-driven slow-slip deformation. To test this hypothesis, this study derives pore pressures in failed and adjacent unfailed deep marine sediments by integrating rock physics models, physical property measurements on recovered sediment core, and wireline logs. Two drill sites (U1394 and U1399)...

S. V., Tamura, Yoshihiko, Villemant, Benoit, and Wang, Fei
Abstract:: Marine sediments around volcanic islands contain an archive of volcaniclastic deposits, which can be used to reconstruct the volcanic history of an area. Such records hold many advantages over often incomplete terrestrial data sets. This includes the potential for precise and continuous dating of intervening sediment packages, which allow a...

New Venture Teams: A Review of the Literature and Roadmap for Future Research

Creator:: Klotz, Anthony C., Hmieleski, Keith M., Bradley, Bret H., and Busenitz, Lowell W.
Abstract:: As entrepreneurship research has matured, scholars have increasingly recognized that the formation of new ventures is commonly accomplished by teams as opposed to lone entrepreneurs. Over the past two decades, the upper echelons perspective has served as the primary lens for investigating new venture team functioning and performance. However, researchers...

Associations between Mycobacterium avium subsp. paratuberculosis antibodies in bulk tank milk, season of sampling and protocols for managing infected cows

Creator:: Cazer, Casey L., Mitchell, Rebecca M., Cicconi-Hogan, Kellie M., Gamroth, Michael, Richert, Roxann M., Ruegg, Pamela L., and Schukken, Ynte H.
Abstract:: BACKGROUND: The objective of this study was to identify associations between the concentration of Mycobacterium avium subsp. paratuberculosis (MAP) antibodies in bulk milk and potential risk factors in herd management and herd characteristics, explaining high MAP antibody titers in milk. An extensive questionnaire was administered to 292 organic and conventional...

Uncovering the Hidden Excited State toward Fluorescence of an Intracellular pH Indicator

Creator:: Tang, Longteng, Zhu, Liangdong, Wang, Yanli, and Fang, Chong
Abstract:: Intracellular pH (pH(i)) imaging is of paramount importance for life sciences. In this work, we implement the ultrafast electronic and stimulated Raman spectroscopies to unravel the fluorescence mechanism of an excitation-ratiometric pH(i) indicator in basic aqueous solution. After photoexcitation of the pH(i) indicator HPTS, a hidden charge-transfer (CT) state following...

Excited-State Proton Transfer of Photoexcited Pyranine in Water Observed by Femtosecond Stimulated Raman Spectroscopy

Creator:: Han, Fangyuan, Liu, Weimin, and Fang, Chong
Abstract:: We use femtosecond stimulated Raman spectroscopy (FSRS) to illuminate the choreography of intermolecular excited-state proton transfer (ESPT) of photoacid pyranine (8-hydroxypyrene-1,3,6-trisulfonic acid, HPTS) in water. The multidimensional reaction coordinate responsible for photoacidity is revealed to involve sequential activation of characteristic skeletal motions during the ca. 1 ps preparation stage preceding...
