TCCON data from Wollongong (AU), Release GGG2014.R0
No full textThe Total Carbon Column Observing Network (TCCON) is a network of ground-based Fourier Transform Spectrometers that record direct solar absorption spectra of the atmosphere in the near-infrared. From these spectra, accurate and precise column-averaged abundances of atmospheric constituents including CO2, CH4, N2O, HF, CO, H2O, and HDO, are retrieved. This data set contains observations from the TCCON station at Wollongong, Australia.Contact person: David Griffith [email protected]

Isotope labeling reveals contribution of newly fixed carbon to carbon storage and monoterpenes production under water deficit and carbon limitation
No full textSecondary metabolites play important roles in plant responses to environmental stress but may also represent a large carbon (C) cost, resulting in trade-offs with other C sinks like growth and storage. However, it remains uncertain how such trade-offs may vary with changes in resource availability including water and CO2 availability. We conducted a glasshouse experiment with peppermint (Mentha x piperita L.) exposed to four treatments: control (sufficient irrigation and near-ambient CO2), water deficit (50% irrigation and near-ambient CO2), CO2 limitation (sufficient irrigation and below-ambient CO2) and the combination of water and CO2 deficits. Continuous 13CO2 labelling was used to trace allocation of newly-assimilated C. Concentrations of soluble sugars significantly increased under water deficit but decreased along with aboveground biomass under low CO2, while monoterpene concentrations remained relatively constant, independent of treatments. Under water deficit, there were no differences in allocation of new vs old C to monoterpenes production, structural growth and storage; plants grown under low CO2 even invested proportionally more newly-assimilated C for monoterpenes production, suggesting a preferential allocation to defense at the expense of growth. We concluded that C allocation to monoterpenes is actively regulated in coordination with growth and storage under water and C stresses, consistent with an optimal defense strategy to protect young tissues

No full textSingle- and Multi-carrier Quadrature Amplitude Modulation Principles and Applications for Personal Communications, WLANs and Broadcasting L. Hanzo Department of Electronics and Computer Science, University of Southampton, UK W. Webb Motorola, Arlington Heights, USA formerly at Multiple Access Communications Ltd, Southampton, UK T. Keller Ubinetics, Cambridge Technology Centre, Melbourn, UK formerly at Department of Electronics and Computer Science, University of Southampton, UK Motivated by the rapid evolution of wireless communication systems, this expanded second edition provides an overview of most major single- and multi-carrier Quadrature Amplitude Modulation (QAM) techniques commencing with simple QAM schemes for the uninitiated through to complex, rapidly-evolving areas, such as arrangements for wide-band mobile channels. Targeted at the more advanced reader, the multi-carrier modulation based second half of the book presents a research-orientated outlook using a variety of novel QAM-based arrangements. * Features six new chapters dealing with the complexities of multi-carrier modulation which has found applications ranging from Wireless Local Area Networks (WLAN) to Digital Video Broadcasting (DVB) * Provides a rudimentary introduction for readers requiring a background in the field of modulation and radio wave propagation * Discusses classic QAM transmission issues relevant to Gaussian channels * Examines QAM-based transmissions over mobile radio channels * Incorporates QAM-related orthogonal techniques, considers the spectral efficiency of QAM in cellular frequency re-use structures and presents a QAM-based speech communications system design study * Introduces Orthogonal Frequency Division Multiplexing (OFDM) over both Gaussian and wideband fading channels By providing an all-encompassing self-contained treatment of single- and multi- carrier QAM based communications, a wide range of readers including senior undergraduate and postgraduate students, practising engineers and researchers alike will all find the coverage of this book attractive

Poets on place: tales and interviews from the road
No full textIncludes index.Out to see America and satisfy his travel bug, W.T. Pfefferle resigned from his position as director of the writing program at Johns Hopkins University and hit the road to interview sixty-two poets about the significance of place in their work. The lively conversations that resulted may surprise with the potential meanings of a seemingly simple concept. This gathering of voices and ideas is illustrated with photo and word portraits from the road and represented with suitable poems. The poets are James Harms, David Citino, Martha Collins, Linda Gregerson, Richard Tillinghast, Orlando Ricardo Menes, Mark Strand, Karen Volkman, Lisa Samuels, Marvin Bell, Michael Dennis Browne, David Allan Evans, David Romtvedt, Sandra Alcosser, Robert Wrigley, Nance Van Winckel, Christopher Howell, Mark Halperin, Jana Harris, Sam Hamill, Barbara Drake, Floyd Skloot, Ralph Angel, Carol Muske-Dukes, David St. John, Sharon Bryan, Donald Revell, Claudia Keelan, Alberto Rios, Richard Shelton, Jane Miller, William Wenthe, Naomi Shihab Nye, Peter Cooley, Miller Williams, Beth Ann Fennelly, Natasha Trethewey, Denise Duhamel, Campbell McGrath, Terrance Hayes, Alan Shapiro, Nikki Giovanni, Charles Wright, Rita Dove, Henry Taylor, Dave Smith, Nicole Cooley, David Lehman, Lucie Brock-Broido, Michael S.

[Review of] William N. Fenton. The False Faces of the Iroquois
No full textThis scientific and artistic tome on Iroquois Indian masks, literally a coffee table book, has been a long time in production. It is the culmination of over sixty years of interest and study by William N. Fenton, deservedly acknowledged as the dean of Iroquois studies. The author\u27s interest in the subject began during his childhood when he spent summers at his family\u27s farm in up-state New York. His grandfather, W.T. Fenton, had obtained two masks from Amos Snow, an Iroquois friend and neighbor, during the mid-nineteenth century. His father, J. W. Fenton, acquired more than a dozen additional masks as part of his vocation as an artist. So it is not surprising that the young William Fenton turned to anthropology in college and returned to the descendants of Amos Snow to pursue his consuming interests in Iroquois culture and history. Fenton\u27s first article on Iroquois masks and the Society of Faces was published in 1937. During subsequent decades, he studied over 1,500 masks in museums and private collections throughout the United States, Canada, and Europe
