The American genera of Simaroubaceae and their distribution Os gêneros americanos de Simaroubaceae e sua distribuição
Autor: W. W Thomas
Publikováno v: Acta Botânica Brasílica, Vol 4, Iss 1, Pp 11-18 (1990)
A review of the phylogenetic relationships of the subfamilies of Simaroubaceae is presented and the distribution patterns of the American genera are discussed. Engler's six subfamilies are evaluated and the three subfamilies represented in the Americ

Use of bromine levels in airborne particulate samples to infer vehicular lead concentrations in the atmosphere
Autor: A.T. Pearce, G. C. Kerrigan, B. H. O'Connor, W. W. Thomas
Publikováno v: Atmospheric Environment (1967). 11:635-638
X-ray fluorescence analysis has been employed to assess the feasibility of using the mean Br/Pb ratio for motor spirit to convert the Br level for atmospheric particulates to an atmospheric vehicular lead level. Analysis of air samples in Perth, West

Analysis of the heavy element content of atmospheric particulate fractions using X-ray fluorescence spectrometry
Autor: W. W. Thomas, G. C. Kerrigan, R. Gasseng, B. H. O'Connor
Publikováno v: X-Ray Spectrometry. 4:190-195
Techniques have been developed for analysing the heavy element content of atmospheric particulate fractions by means of X-ray fluorescence spectrometry. Special attention is devoted to the nondestructive analysis of particulates collected on the cell

The analysis of Nickel, Gallium and Germanium in iron meteorites by X-Ray fluorescence spectrometry
Autor: W. W. Thomas, J. R. De Laeter
Publikováno v: X-Ray Spectrometry. 1:143-146
An X-ray spectrometric technique is described which enables nickel, gallium and germanium to be analysed in iron meteorites. It is important to know the concentration of these elements with sufficient accuracy in order to chemically classify iron met

Integrated Control as an Improved Means of Reducing Populations of Tobacco Pests1
Autor: W. W. Thomas, C. R. Gentry, J. M. Stanley
Publikováno v: Journal of Economic Entomology. 62:1274-1277
Integrated control of the 4 major pests that attack the foliage of cigar-wrapper tobacco was attempted near Quincy. Florida, in 1965-66. Treatments consisted of (I) a preplanting application of disulfoton granules (10%) to the soil in control the tob

Turbotip Lift Fan Design
Autor: W. W. Thomas
Publikováno v: ASME 1972 International Gas Turbine and Fluids Engineering Conference and Products Show.
This paper discusses the basic design approach and features of the turbotip lift fan concept, initially developed for application in the XV-5 VTOL research aircraft. Design changes necessary to meet the requirements of the proposed NASA V/STOL transp
