Plumbing the Global Carbon Cycle: Integrating Inland Waters into the Terrestrial Carbon Budget

by J. J. Middelburg, J. Melack
"... Because freshwater covers such a small fraction of the Earth’s surface area, inland freshwater ecosystems (particularly lakes, rivers, and reservoirs) have rarely been considered as potentially important quantitative components of the carbon cycle at either global or regional scales. By taking publi ..."

"... Antarctica has allowed the extension of the ice record of atmospheric composition and climate to the past four glacial-interglacial cycles. The succession of changes through each climate cycle and termination was similar, and atmospheric and climate properties oscillated between stable bounds. Inte ..."

In vivo gene delivery and stable transduction of nondividing cells by a lentiviral vector

by Luigi Naldini, Ulrike Blomer, Daniel Ory, Richard Mulligan, Fred H. Gage, Inder M. Verma, Didier Trono - Science , 1996
"... A retroviral vector system based on the human immunodeficiency virus (HIV) was de-veloped that, in contrast to a murine leukemia virus-based counterpart, transduced heterologous sequences into HeLa cells and rat fibroblasts blocked in the cell cycle, as well as into human primary macrophages. Additi ..."

A biochemical model of photosynthetic CO2 assimilation in leaves of C3 species

by G. D. Farquhar, S. Von Caemmerer, J. A. Berry - Planta , 1980
"... Abstract. Various aspects of the biochemistry of photosynthetic carbon assimilation in C3 plants are integrated into a form compatible with studies of gas exchange in leaves. These aspects include the kinetic properties of ribulose bisphosphate carboxylase-oxygenase; the requirements of the photosyn ..."

Response of a Coupled Ocean–Atmosphere Model to Increasing Atmospheric Carbon Dioxide: Sensitivity to the Rate of Increase

by Ronald J. Stouffer, et al. - JOURNAL OF CLIMATE , 1999
"... The influence of differing rates of increase of the atmospheric CO 2 concentration on the climatic response is investigated using a coupled ocean–atmosphere model. Five transient integrations are performed each using a different constant exponential rate of CO 2 increase ranging from 4 % yr �1 to 0. ..."

G.: Primary production of the biosphere: Integrating terrestrial and oceanic components

by Christopher B. Field, Michael J. Behrenfeld, James T. R, Paul Falkowski - Science , 1998
"... Integrating conceptually similar models of the growth of marine and terrestrial primary producers yielded an estimated global net primary production (NPP) of 104.9 petagrams of carbon per year, with roughly equal contributions from land and oceans. Approaches based on satellite indices of absorbed s ..."

CACTI 3.0: An Integrated Cache Timing, Power, and Area Model

by Premkishore Shivakumar, Norman P. Jouppi, Premkishore Shivakumar , 2001
"... CACTI 3.0 is an integrated cache access time, cycle time, area, aspect ratio, and power model. By integrating all these models together users can have confidence that tradeoffs between time, power, and area are all based on the same assumptions and hence are mutually consistent. CACTI is intended fo ..."
