Extended Rein-Sehgal model for tau lepton production
The polarization density matrix formalism is employed to include the final
lepton mass and spin into the popular model by Rein and Sehgal for single pion
neutrinoproduction. We investigate the effect of the lepton mass on the
differential cross sections. The lepton polarization evaluated within the
extended RS model is compared against that follows from the single resonance
production model based upon the Rarita-Schwinger formalism with
phenomenological transition form factors.Comment: Contribution to the 3rd International Workshop on Neutrino-Nucleus

Lepton Polarization in Neutrino-Nucleon Interactions
We derive generic formulas for the polarization density matrix of leptons
produced in neutrino and antineutrino collisions and briefly consider some
important particular cases. Next we employ the general formalism in order to
include the final lepton mass and spin into the popular model by Rein and
Sehgal for single pion neutrinoproduction.Comment: Talk given at 10th International Workshop on High-Energy Spin Physics

Polarization of Tau Leptons Produced in Quasielastic Neutrino--Nucleon Scattering
A numerical analysis of the polarization vector of tau leptons produced
through quasielastic neutrino and antineutrino interactions with free nucleons
is given with two models for vector electromagnetic form factors of proton and
neutron. The impact of G parity violating axial and vector second-class
currents is investigated by applying a simple heuristic model for the induced
scalar and tensor form factors.Comment: Thesis of a talk given at the 8th Scientific Conference (SCYSS-04),

Assessment of the role of the state in the management of mineral resources
Mineral resources as natural capital can be transformed into human, social and physical capital, that guarantees the sustainable development of a country, exclusively through professional public management. Public management of a country's mineral resource potential is seen as an element of transnational governance. Regulation involves the use of laws, rules and regulations within the jurisdictional and sectoral capabilities of the state, minimizing its involvement as a producer. The features of the ideology of economic liberalism, which polarizes the societies of raw material producing countries by imposing austerity, as well as lowering trade barriers have been studied. The analysis of the influence of the radical new order of neoliberal world ideology on the development of the extractive sector and the strengthening of state regulation has been presented
