Samples of brazilian calcite, exposed to gamma radiation in laboratory and heated at constant rate of 2.7(sup 0) C/s, showed three glow peaks at 150, 250 and 350 (sup 0)C in their thermoluminescent emission curves. The analysis of these peaks, using diffe...

The natural rubber latex was vulcanized by two different process: (a) thermal process in the presence of sulfur; (b) alternative process using radiation (gamma rays and electrons beam). The comparative study of rubber goods quality (surgical gloves and ba...
This work made on radiation vulcanization of natural rubber latex process by gamma rays from (sup 60) Co source and electron beam of 1.5 MeV, 25 m A by Dynamitron, instead of classic process using sulfur. The experiment was carried out to study the influe...
N,N' -dimethyl acrylamide (DMAA) graft copolymerization onto polyethylene films was carried out, using a organic solvent as a reaction medium and gamma rays from a (sup 60) Co source for surface activation. Thermal analysis revealed the crystallinity and ...
Genetical analysis procedures of the cobalt 60 gamma radiation effects in the induced mutations in quantitative characters of Caupi BR-1 Poty. The following characters were evaluated: day to first flower (FI), number of pods per plant (NVP), pod lenght (C...
The photonuclear cross sections of U-293 and Pu-239 have been studied by using monochromatic and discrete photons, in the energy interval from 5.49 to 9.72 MeV, produced by thermal neutron capture. The gamma fluxes incident on the samples were measured us...
Variabilidade � tipicamente uma caracter�stica de AGNs, sendo observada em toda a faixa eletromagn�tica. Em rela��o �s escalas de tempo, varia��es desde horas at� de algumas d�cadas foram encontradas por v�rios autores. Em alguns casos, an�lises temporais de curvas de luz mostram a exist�ncia de periodicidade nas varia��es observadas. Um exemplo ...

The use of plant tissue culture and the application of gamma radiation as mutation inducing agents, in the sugar cane plant, variety NA 5679, are studied. The variation in the contents of brix, pol, fiber, purity, extraction, phosphorus, nitrogen, reducin...
The steriling doses for different phases of evolutive cycle of Plodia interpunctella (Huebner, 1813) (Lepidoptera - Pyralidae) worm using gamma radiation is studied. (author). (Atomindex citation 23:086289)
This work was carried out in the Entomology Section of the Centre of Nuclear Energy in Agriculture (CENA), University of Sao Paulo, Piracicaba, Sao Paulo, Brazil. The objective of the present research work was to investigate some effects of gamma radiatio...
