Phases and phase transitions in spin-triplet ferromagnetic superconductors

Recent results for the coexistence of ferromagnetism and unconventional superconductivity with spin-triplet Cooper pairing are reviewed on the basis of the quasi-phenomenological Ginzburg-Landau theory. New results are reported. The results are discussed in view of applications to metallic compounds as UGe2, URhGe, ZrZn2.Comment: 32 pages, 5 figs, Miktex; Chapter in ``Progress in Ferromagnetism Research'' (NOVA, N. Y., 2004

Diamagnetic susceptibility of spin-triplet ferromagnetic superconductors

We calculate the diamagnetic susceptibility in zero external magnetic field above the phase transition from ferromagnetic phase to phase of coexistence of ferromagnetic order and unconventional superconductivity. For this aim we use generalized Ginzburg-Landau free energy of unconventional ferromagnetic superconductor with spin-triplet electron pairing. A possible application of the result to some intermetallic compounds is briefly discussed.Comment: 7 pages, 1 figur

New critical behavior in unconventional ferromagnetic superconductors

New critical behavior in unconventional superconductors and superfluids is established and described by the Wilson-Fisher renormalization-group method. For certain ordering symmetries a new type of fluctuation-driven first order phase transitions at finite and zero temperature are predicted. The results can be applied to a wide class of ferromagnetic superconducting and superfluid systems, in particular, to itinerant ferromagnets as UGe2 and URhGe.Comment: 12 pages, 6 fig

About the magnetic fluctuation effect on the phase transition to superconducting state in Al

The free energy and the order parameter profile near the phase transition to the superconducting state in bulk Al samples are calculated within a mean-field-like approximation. The results are compared with those for thin films.Comment: 11 pages, miktex, 2 figure

Обеспечение и защита прав, основных свобод индивидуума осуществляются различными субъектами государства и его институтам. Поэтому исследование и представление новой усовершенствованной методики обучения сотрудников правоохранительных органов и охранных агентств, направленно на предотвращение преступлениям и развития правового безопасного государства.Целью является разработка и практическое применение апробированных методов подготовки, с помощью применения техник по личной защите, взятых с различных боевых искусств, для охраны и обеспечения безопасности граждан. (Ensuring and protecting the rights, fundamental freedoms of the individual are carried out by various subjects of the state andits institutions. Therefore, the research and presentation of a new improved method of training law enforcement offi cers and security agencies, aimed at preventing crime and the development of a lawful safe state. The goal is the development and practical application of proven training methods, using personal protection techniques taken from various martial arts, to protect and ensure the safety of citizens.

ON SOME PHARMACOLOGICAL PROPERТIES OF ТНЕ ALKALOIDS OF VINCA MAJOR

Pharmacological studies of the alkaloids of Vinca minor and Vinca hеrbасеае revealed  that compounds found in these plants аrе highly active pharmacologic agents. Тhеу hаve а sedative effect оn the central nervous system, they considerably lower the blооd pressure, theyblосk some ganglia, belonging to the parasympathetic part of the vegetative nervous system and interrupt the transmission of nervous impulses in the myo-neural synapses, realizing а curare-like effect; they also anesthesize the receptors of the cornea etc. On the basis of these investigations а maгket product was deliveгed under the name of Vincaipan, containing the total alkaloids of Vinca minor, whose previous clinical trial seemed quite encuoraging. All this stimulated the phytochemical and pharmacological elaboration of the third representative of the botanic family Appocynaceae. This plant also belongs to the species Vinca - Vinca major, grown in our country. Mention slhould also bе made of the fact that according to phytochemical investigations of а number of foreign authors Vinca major contains alkaloids with indolic structure, which аrе more or less structurally гelated to гeserpine, whose polypharmacological activity and great therapeutic significance аrе well known.These were the motives fог our systematic pharmaco1logical analysis of the total alkaloids of this plant. obtained at the Chair of Pharmacology at the Higher Medical Institute in Varna.
