By N. S. MIZUNO, V. PEnMAN, F. W. BATES, J. H. SAU’rTER AND M. 0. SCHULrLE SEVERE HYPOPLASIA of the bone marrow,1’2 including any desired degree of thrombocytopenia,3 can be induced in the bovine by feeding of appropriate amounts of trichloroethylene-extracted soybean oil meal ( TCESOM). This affords a unique opportunity for analytic study of thrombocytes from thrombocytopenic animals in which ...

[1] New theoretical considerations indicate that the complementary relationship (CR) of evaporation is inherently asymmetric when the time rate of change between actual and apparent potential evaporations is considered. The theory also estimates the extent of this asymmetry as a function of the surface temperature and predicts that a symmetric CR, independent of the surface temperature, can onl...

R. L. Carter and H. G. Penman (ed.): Infectious Mononucleosis. Blackwell, Oxford/ Edinburgh 1969. 258 p., illustr.; 70s net. This is a timely, useful and unusually interesting book. Viral infections, their impact on the organism and the immunological processes which they induce are much debated. Infectious mononucleosis is a ‘model disease’ and the contributors to this volume succeed in clearly...

I am profoundly grateful to the American Society for Cell Biology for the award to me and my colleague Sheldon Penman of the E.B. Wilson Medal. This occasion presents the opportunity for reflections on a 40year search for indications of how RNA functions as an informational molecule in eukaryotic cells. As will be recounted, this quest began in the late 1950s, before the recognition of mRNA, by...

Correlation of the Priestley-Taylor coefficient value, α, with air humidity and wind speed for obtaining evapotranspiration (ET) values similar to those by the Penman-Monteith equation maybe justified from a strictly utilitarian viewpoint in cases when wind measurements are lacking. However, by doing so, a conflict of scale arises, which leaves ample room for incorrect generalization about the ...

[1] A Bayesian approach was used to fit a conceptual transpiration model to half-hourly transpiration rates for a sugar maple (Acer saccharum) stand collected over a 5-month period and probabilistically estimate its parameter and prediction uncertainties. The model used the Penman-Monteith equation with the Jarvis model for canopy conductance. This deterministic model was extended by adding a n...

Incoming solar radiation derived from GOES-8 satellite observations, in combination with local meteorological measurements, were used to model evapotranspiration from a wetland. The wetland experiment was conducted in the Paynes Prairie Preserve, North Central Florida during a growing season characterized by significant convective activity. The satellite solar radiation measurements generally a...

Water scarcity is one of the most important problems agroecosystems in Mediterranean and semiarid areas, especially for species such as vineyards that largely depend on irrigation. Actual evapotranspiration (ET) a variable represents water consumption crop, integrating climate biophysical variables. models based remote sensing data from visible bands Sentinel-2, including Penman-Monteith–Stewar...

In a text-produqtion system high and special demands are placed on the grammar and the lexicon. This paper will view these comDonents in such a system (overview in section 1). First, the subcomponente dealing with semantic information and with syntactic information will be presented se!:arataly (section 2). The probtems of relating these two types of information are then identified (section 3)....
