The genus Cucurbita has been mentioned as a good source of carotenoids, including β-carotene, which is precursor vitamin A. However, the variability observed for denotes individual need to invest in species. An experiment was carried out with aim evaluating content total carotenoids and β-carotene C. maxima germplasm. Treatments consisted 23 accessions two commercial cultivars maxima. pulp colo...

We investigate hierarchies of semidefinite approximations for the chromatic number χ(G) of a graph G. We introduce an operator Ψ mapping any graph parameter β(G), nested between the stability number α(G) and χ G , to a new graph parameter Ψβ(G), nested between ω(G) and χ(G); Ψβ(G) is polynomial time computable if β(G) is. As an application, there is no polynomial time computable graph parameter...

The physiological cholesterol-lowering benefits of β-glucan have been well documented, however, whether modulation of gut microbiota by β-glucan is associated with these physiological effects remains unknown. The objectives of this study were therefore to determine the impact of β-glucan on the composition of gut microbiota in mildly hypercholesterolemic individuals and to identify if the alter...

Let H be a graph with κ1 components and κ2 blocks, and let G be a minor-minimal 2-connected graph having H as a minor. This paper proves that |E(G)| − |E(H)| ≤ α(κ1 − 1) + β(κ2 − 1) for all (α, β) such that α + β ≥ 5, 2α + 5β ≥ 20, and β ≥ 3. Moreover, if one of the last three inequalities fails, then there are graphs G and H for which the first inequality

Purpose: To investigate the suitability of glucosyl-β-cyclodextrin (G-β-CD) to form inclusion complex with catechin, and characterize the physicochemical properties of the inclusion complex of catechin and G-β-CD. Methods: Catechin and G-β-CD was mixed in water at the same molar ratio, stirred at 20 °C for 48 h and lyophilized to obtain the complex. Its physicochemical properties were investiga...

ABSTRACT : The stability operator of a compact oriented minimal hypersurface Mn−1 ⊂ S is given by J = −∆ − ‖A‖ − (n − 1), where ‖A‖ is the norm of the second fundamental form. Let λ1 be the first eigenvalue of J and define β = −λ1 − 2(n − 1). In [S] Simons proved that β ≥ 0 for any non-equatorial minimal hypersurface M ⊂ S. In this paper we will show that β = 0 only for Clifford hypersurfaces. ...

Fluorophenols are used as agrochemicals and released into environment as pollutants. Cultured marine microalga Amphidinium crassum (Gymnodinium) glucosylated 2-fluorophenol (1), 3-fluorophenol (2), and 4-fluorophenol (3) to the corresponding β-D-glucosides, ie, 2-fluorophenyl β-D-glucoside (4, 60 μg/g cells), 3-fluorophenyl β-D-glucoside (5, 20 μg/g cells), and 4-fluorophenyl β-D-glucoside (6, ...

The purpose of this note is to prove the existence of ‘nice’ components of the Hilbert scheme of curves C ⊆ P × P of genus g and bidegree (k, d). We can also phrase our result using the Kontsevich moduli space of stable maps to P × P. For a smooth projective variety Y and a class β ∈ H2(Y,Z), one considers the moduli space Mg(Y, β) of stable maps f : C → Y , with C a reduced connected nodal cur...
