    Notes: Abstract We study the problem of the computation of the square-free decomposition for polynomials over fields of positive characteristic. For fields which are explicitly finitely generated over perfect fields, we show how the classical algorithm for characteristic zero can be generalized using multiple derivations. For more general fields of positive characteristic one must make an additional constructive hypothesis in order for the problem to be decidable. We show that Seidenberg'sCondition P gives a necessary and sufficient condition on the fieldK for computing a complete square free decomposition of polynomials with coefficients in any finite algebraic extension ofK.

    Notes: Adjuvants are agents that can induce strong immunity to different antigens. They are thought to act mainly by stimulating macrophages, causing the release of cytokines, which in turn induce an inflammatory focus necessary for the adjuvant action. The authors found that catalase, ascorbic acid, N-acetylcysteine and glutathione are able to inhibit the enhancing effect of incomplete Freund adjuvant (IFA) and polyoxyethylated castor oil upon the humoral immune response to sheep red blood cells (SRBC). None of the anti-oxidants tested inhibited the basal immune response to the antigen. In addition, mice inoculated with different concentrations of hydrogen peroxide showed an enhanced response against SRBC, mimicking the effect observed with adjuvants. Delayed type hypersensitivity induced by SRBC in the presence of IFA was also inhibited by catalase. In conclusion, the report indicates that oxygen radicals are crucial molecules involved in the adjuvant effect observed in SRBC immunized mice.
