Model of Plane Distribution of Heat Sources for Multi-Channel Matrix Oxygen Sensors

Transcutaneous polarography is one of the most objective noninvasive assessment of the capillary blood flow and microcirculation by controlling the oxygen partial pressure in the subcutaneous tissue. The outcome of research is influenced by such common factors as the oxygen content in the ambient air, the adequacy of the central hemodynamics of the patient, the presence of violations of the transport function of the blood, the pathology of the pulmonary system and local factors (disturbance of the local microcirculation, tissue edema, marked capillary spasm, etc.).

Stationary Magnetic Interactional Magnetization Waves in Ferromagnetic with Easy-Axis Anisotropy

Results of research have shown that in regular ferrite-garnet films with perpendicular lightweight anisotropy in parallel to the film plane magnetic field long-wave inhomogeneous magnetic configuration of harmonic type can be created and observed. Field removes devolution in the direction of magnetization and promotes the formation of inhomogeneous magnetic configuration. During the work it was thought that the magnetic field is close to the critical value at which film homogeneously magnetization happens.

The active thermal stabilization process in the system of combined resistancemagnetic first order phase transition

This paper analyzes the process of active thermal stabilization in a longitudinal magnetic field. Specifically, we calculate a part of ferromagnetic phase and temperature of the system (opening, ferromagnetic and paramagnetic layers). We demonstrate that the device’s chart enables efficient thermoregulation implementation. Furthermore, we obtain an inequality which determines the system performance, whose range is wide enough to ensure the mode of active thermal stabilization and not to cause fundamental difficulties.

Using the elements of domain structures of iron garnet films while transporting magnetic microparticles

This study theorizes and experimentally tests the concept of movement of micron- and submicron magnetic particles along the surface of iron garnet films in the field of dispersal of isolated moving strip domain. We show that magnetic particles can be moved by pushing them to the position in front of the moving domain due to the specificity of fields’ distribution.
