Summary One-year experiments conducted with one hemp variety were established to determinate the cultivation practices (growth density and pinching) which could be used optimize technological process of varieties production for different purposes. The results showed that reduced crop pinching result in development shorter plants. In denser non-pinched crops, stem is over 180 cm high, while plan...

A bstract Using the spectral functions measured in ? decays, we investigate actual numerical impact of duality violations on extraction strong coupling. These effects are tiny standard ? s ( $$ {m}_{\tau}^2 m ? 2 ) determinations from integrated d...

In this paper, we generalize Bonahon’s characterization of geometrically infinite torsion-free discrete subgroups of PSL(2,C) to geometrically infinite discrete torsionfree subgroups Γ of isometries of negatively pinched Hadamard manifolds X. We then generalize a theorem of Bishop to prove that every such geometrically infinite isometry subgroup Γ has a set of nonconical limit points with cardi...

A class of skew products over irrational rotations of the circle is defined which contains some systems which have strange nonchaotic attractors. The global attractor of these systems is characterized: it lies between an upper semi-continuous curve and a lower semi-continuous curve. With additional assumptions on the class of maps considered more detail of the attractor can be given. Mathematic...

We say that Γ has uniform exponential growth if Ent Γ > 0. In [11], remarque 5.12, M. Gromov raised the question whether exponential growth always implies uniform exponential growth. The answer is negative, indeed, in [14] J.S. Wilson gave examples of finitely generated groups of exponential growth and non uniform exponential growth. Nevertheless, exponential growth implies uniform exponential ...
