Stabilization of the mean wavelength of an erbium-doped fiber source as part of high-accuracy FOG with increased spectrum width.

The mean wavelength, spectrum width, and optical power of the output light of an erbium-doped fiber source (EDFS) are key parameters for navigation systems based on navigation-grade and strategic-grade fiber optic gyroscopes (FOGs). We propose a method of simultaneous stabilization for EDFS parameters. The essence of this method is to stabilize the constant values of the mean wavelength and optical power by real-time adjustment of the two laser diodes' pump ratios during temperature changes using an EDFS double-pass bidirectional optical scheme with the unpumped erbium-doped fiber.

Lumbar Spinal Fusion Using Lateral Oblique (Pre-psoas) Approach (Review).

Unlabelled: Lumbar spinal fusion is one of the most common operations in spinal surgery. For its implementation, anterolateral (pre-psoas) approach (oblique lumbar interbody fusion, OLIF) is now increasingly used due to its high efficacy and safety. However, there is still little information on the clinical and radiological results of using this technique.

Liver Hemostasis by Using Cold Plasma.

Surgical resection is associated with blood loss and bacterial infections. The aim of this study was to evaluate the effectiveness of cold plasma treatment during liver resection. Thirty adult male Wistar rats were divided randomly into 2 groups.

[Morphofunctional Changes of Spleen After Hemostasis by Nonequilibrium Plasma].

Background: Heavy bleeding is developed in case of spleen injury. It often leads to death. At present the search and development of new methods for hemostasis of spleen bleeding continues.

[Ozone therapy for radiation reactions and skin lesions after neutron therapy in patients with malignant tumors].

The article discusses the problem of radiation complications from normal tissues in patients after therapy with fast neutrons of 6.3 MeV. The methods of treatment using ozone technologies in patients with radiation reactions and skin lesions on the areas of irradiation after neutron and neutron-photon therapy have been worked out.
