instrument measures radiances in eight narrow spectral bands of the visible and near infrared spectrum. Two of them are centered on the 02 A-band in order to infer cloud pressure. By assuming the atmosphere behaves as a pure absorbing medium overlying a perfect reflector, an "apparent" pressure Papp is derived from POLDER data. For validation purposes, Papp(More)
The platelets from normal rats interact with microfilariae of Dipetalonema viteae in vitro in the presence of antibodies leading to the killing of the parasite. The antibody involved in this reaction is identified as IgE because the absorption of immune rat serum on anti-rat IgE column or the pretreatment of platelets with anti-Fc epsilon receptor resulted(More)
The primary purpose of this study is to assess the performance of 1D solar radiative transfer codes that are used currently both for research and in weather and climate models. Emphasis is on interpretation and handling of unresolved clouds. Answers are sought to the following questions: (i) How well do 1D solar codes interpret and handle columns of(More)
[1] Computation of components of shortwave (SW) or solar irradiance in the surface-atmospheric system forms the basis of intercomparison between 16 radiative transfer models of varying spectral resolution ranging from line-by-line models to broadband and general circulation models. In order of increasing complexity the components are: direct solar(More)
Neutrophils from the peripheral washings of normal rats in the presence of sera obtained from rats immune to circulating microfilariae adhered to and killed the microfilariae of Dipetalonema viteae in vitro within 16-24 hr. No significant adherence or cytotoxicity was mediated by sera collected from animals with a high microfilaraemia or from normal rats.(More)
We have previously reported (Nature 1982. 299:361) that the transplacental transfer of Dipetalonema viteae microfilariae (mf) can induce an antigen-specific tolerance in rats. Rats thus tolerized have serum factor(s) which block(s) antigen-specific lymphocyte proliferation. The results of experiments involving fractionation of antisera from tolerant animals(More)
