superimposing an external magnetic field (applied parallel or
perpendicular to the cathode surface). The films were compared
with similar samples obtained in the absence of external applied
magnetic field. The modifications induced by magnetic field in
the morphology of the films were explained by the specific local
convection of ions at the cathode-electrolyte interface, which
promotes changes both in the electrical charge of the double
layer and in the thickness of the diffusion layer. It was observed
that an induced anisotropy appeared in the Co-Ni-N films due to
the preferential orientation of the easy axis of magnetization as a
function of the magnetic field direction. These observed
phenomena could be explained by magneto-hydrodynamic
(MHD) convection of charged ions induced by Lorentz force at
the electrode/electrolyte interface. Co–Ni–N films display
tunneling magnetoresistance effect which could be explained
mainly by the elastic spin dependent scattering of conduction
electrons at the interface between magnetic grains (constituted of
Co–Ni solid solution) and nonmagnetic regions (aluminium
oxidized substrate)

For the protection of various materials used by people,
should know well enough the effects of biocides that them may
have on our health and environment, so we can minimize
undesirable effects, by their choice in full compliance with the
requirements. Biocidal products are active substances or groups
of substances that prevent, neutralize and control exercise effect
on any harmful organism by chemical or biological means.
The aim of the thesis is to provide those interested an
analysis tool of most commonly used biocides for the protection
of various materials in a wide range of industries.
We have a large amount of information but which can not
be properly understood if we do not have a database type
application, enabling rapid information processing and sorting,
extracting them by means of various search criteria (toxicity,
antimicrobial activity, application field such as: textile and
leather industries, plastics, cosmetics, pharmaceutical, food,
environment etc). We designed and developed a database in
which we introduced useful information for the most common
biocides this can be supplemented and updated later with other
