In this paper, the quantitative structure-activity relationship predictive models (QSAR) are presented: prediction model for some of main components cannabis sativa, acute toxicity LD50 (n=45, r2=0.917, q2=0.902), chronic LOAEL (n=35, r2=0.911, q2=0.868), NOAEL(n=22, r2=0.964, q2=0.937), LOEL (n=26, q2=0.863) and NOEL (n=25, r2=0.867, q2=0.802), in addition to carcinogenicity mutagenicity effec...

We show that a suitable 2-dimensional linear system of Hermitian curves of PG(2, q2) defines a model for the Desarguesian plane PG(2, q). Using this model we give the following group-theoretic characterization of the classical unitals. A unital in PG(2, q2) is classical if and only if it is fixed by a linear collineation group of order 6(q + 1)2 that fixes no point or line in PG(2, q2).

We study arithmetical and geometrical properties of maximal curves, that is, curves defined over the finite field ¥q2 whose number of ¥q2 -rational points reachs the Hasse-Weil upper bound. Under a hypothesis on non-gaps at rational points we prove that maximal curves are ¥q2 -isomorphic to y q + y = x for some m £ Z + .

the mass of a hypothetical right-handed W boson.The single differential NC (CC) cross sections dσ/dQ2, dσ/dx and dσ/dy are presented for Q2 > 185 GeV2 (Q2 > 200 GeV2). The reduced NC (CC) cross sections σ̃ are presented. The structure function xF̃3 is determined by combining the e+p NC reduced cross sections with the previously measured e−p [2] measurements. Reduced cross sections from a high-Q2 ...
