Applications of quadratic D-forms to generalized quadratic forms

In this paper, we study generalized quadratic forms over a division algebra with involution of the first kind in characteristic two. For this, we associate to every generalized quadratic from a quadratic form on its underlying vector space. It is shown that this form determines the isotropy behavior and the isometry class of generalized quadratic forms.

Multilinear forms which are products of linear forms

The conditions under which, multilinear forms (the symmetric case and the non symmetric case),can be written as a product of linear forms, are considered. Also we generalize a result due to S.Kurepa for 2n-functionals in a group G.

Biochemical and developmental characterization of multiple forms of catalase in tobacco leaves.

Leaf extracts of both Nicotiana tabacum and Nicotiana sylvestris contain multiple forms of catalase (H(2)O(2):H(2)O(2) oxidoreductase, EC 1.11.1.6) which are separable at different pH values by chromatofocusing columns. Marked changes in distribution of these catalases occur during seedling development and leaf maturation. The form of catalase eluting first (peak 1) was predominant during early...

Antioxidant and antifungal activities of Camellia sinensis (L.) Kuntze leaves obtained by different forms of production.

The antioxidant and anticandidal activities of leaves obtained from Camellia sinensis by non-fermentation (green and white teas), semi-fermentation (red tea) and fermentation method (black tea) were investigated. It was evaluated the total phenolic content by Folin-Ciocalteau assay; antioxidant capacities were evaluated in vitro using DPPH and ABTS radicals, hypochlorous acid and superoxide ani...

Expression of multiple forms of ferredoxin NADP+ oxidoreductase in wheat leaves.

In higher plants there are two forms of ferredoxin NADP(+) oxidoreductase (FNR), a photosynthetic pFNR primarily required for the photoreduction of NADP(+), and a heterotrophic hFNR which generates reduced ferredoxin by utilizing electrons from NADPH produced during carbohydrate oxidation. The aim of this study was to investigate the presence of multiple forms of FNR in wheat leaves and the cap...
