Grape must mineralization by high pressure microwave digestion for trace elemen...
Catarino, S.; Trancoso, I.M.; Sousa, Raul Bruno de; Curvelo-Garcia, A.S.Analytical Note ; The present work describes the development and validation of a high pressure microwave-assisted mineralization procedure for the determination of metals in grape must by spectrometric techniques. Metals of special oenological and food safety importance (Al, Co, Cu, Cd, Pb) were used as model elements to achieve the optimum working conditions. The study was conducted by monitoring their concen...
Determination of cobalt in wine and must by electrothermal atomization atomic a...
Sousa, Raul Bruno de; Catarino, S.; Neves, A.An electrothermal atomization atomic absorption spectrometry method was optimized to quantify cobalt in musts and wines, especially within quality control scope. As far as wine samples are concerned, the method involves reduced risk of contamination by eliminating prior treatment other than dilution (1:2). For must samples a pre-treatment is needed, in order to destroy the organic matter that could interfere wi...
Identification and physical mapping of induced translocation breakpoints involv...
Catarino, S.; Alvarez, E.; Campa, A.; Vieira, R.; Roca, A.; Giraldez, R.Abstract To obtain translocations involving specific chromosomes in rye, pollen of a line in which chromosome 1R has large C-bands on its two telomeres, but which lacks C-bands (or has very small ones) on the telomeres of the remaining chromosomes, was X-irradiated. All translocations involving the labelled chromosome (1R) could be easily recognized in C-banded mitotic metaphases. The non-labelled chromosome i...
