Magic angle effects and angular magnetoresistance oscillations as dimensional crossovers.

Interference effects between velocity and density of states, which occur as electrons move along open orbits in the extended Brillouin zone in anisotropic conductors, result in a change of wave functions' dimensionality at magic angle (MA) directions of a magnetic field. In particular, these 1D-->2D dimensional crossovers result in the appearance of sharp minima in a resistivity component rho perpendicular (H,alpha), perpendicular to conducting layers. This explains the main qualitative features of MA and angular magnetoresistance oscillations' phenomena observed due to the existence of quasi-one-dimensional sheets of Fermi surface in (TMTSF)2X, (DMET-TSeF)2X, and kappa-(ET)2Cu(NCS)(2) conductors.

[Problems of hemostasis and hermetic properties in liver resections with application of fibrin-collagen substance].

Forty-seven patients with various diseases of the liver were treated from 1992 to 2002. Patients had undergone liver resections of different scope. In 20 patients (study group) wound covering "Tachokomb" was used for final hemostasis and high hermetic properties of wound surface. Conventional suturing of the vessels and bile ducts was performed in 27 patients of the control group. Reliable hemostasis of the hepatic stump after anatomic resection was achieved in all the patients of the study group. Application of wound covering decreased time of final hemostasis, severity of hemorrhage and blood transfusion during surgery. Biliary complications after surgery were seen more often. Application of combined glue composition failed to reduce significantly rate of biliary complications after surgery, their rate increased proportionally to extension of liver resection.
