Charge Transfer, Change of the Spin Value, and Driving of Magnetic Order by Pressure in Bimetallic Molecular Complexes.

The magnetic bimetallic molecular-based compounds attract considerable attention because of their unique characteristics which are very different from those of traditional magnets. We demonstrate the effects of charge transfer as well as spin and magnetic order changes induced by high hydrostatic pressure applied to the two bimetallic multifunctional Prussian blue analogues, KCo[Fe(CN)]·18HO and KMn[Fe(CN)]·6HO. Two opposite directions of change in their properties under pressure are revealed: (i) the magnetization reduction and magnetic order disappearing for the KCo[Fe(CN)]·18HO compound and (ii) an increase of the magnetization and change of the sign of exchange coupling for the KMn[Fe(CN)]·6HO compound.

Comparative efficiency analysis of fiber-array and conventional beam director systems in volume turbulence.

The performance of two prominent laser beam projection system types is analyzed through wave-optics numerical simulations for various atmospheric turbulence conditions, propagation distances, and adaptive optics (AO) mitigation techniques. Comparisons are made between different configurations of both a conventional beam director (BD) using a monolithic-optics-based Cassegrain telescope and a fiber-array BD that uses an array of densely packed fiber collimators. The BD systems considered have equal input power and aperture diameters.

RESULTS OF HIP ARTHROPLASTY AFTER OSTEOSYNTHESIS OF PROXIMAL FEMUR.

The hip arthroplasty in case of destructive - dystrophic affection is considered as the most effective method, which provided social and home reintegration. A modern science development facilitates to this technique. However, specialists noted that the rate of endoprosthesis complication increased in the patients after osteosynthesis of proximal femur.

[Magnetic resonance imaging in the diagnosis of lacrimal tract pathology].

Magnetic resonance imaging (MRI) was used to examine 45 patients (23 females and 22 males) aged 16-67 years with lacrimal tract pathology on a Sigma Gorizont magnetic resonance (MR) tomograph ("General Electric"). This yielded head MR scans in the frontal, axial, and sagittal projections. The thickness of MR sections was 2-3 mm.

[On validity of intralacunar exposure to surgical laser beam in chronic tonsillitis (experimental study)].

An experimental study was made on the removed tonsil to validate clinical efficiency of intralacunar impact of surgical laser beam. The experiment was based on computed tomography of the removed tonsil with intralacunar introduction of the contrast medium before and after intralacunar impact of surgical laser beam. The study demonstrates changes in the lacunar apparatus of the palatine tonsils in response to laser beam radiation.

[A method of preparing a transplant for eliminating defects and deformities in the supporting facial tissues].

A method for making transplants for repair of abutment tissue defects and deformations based on computer technology is proposed. The technology unites surgical treatment, clinical and x-ray computer-aided diagnosis, computer processing of information and models, experiments, and production. Correspondence of the implant to repaired structures, site of implantation, and individual defect was confirmed experimentally [5], clinically [10], and by control computer-aided tomography.

[Comparison of the results of roentgenography, panoramic zonography and computer-aided tomography in some deformations of facial skull].

Fifty patients with congenital and posttraumatic deformations of the facial skull were examined using effective diagnostic schemes of x-ray examination (including panoramic roentgenography and sonography) and computer-aided tomography. The methods were found to supplement each other. Computer-aided tomography is more useful in posttraumatic deformations, for it helps specify the status of accessory nasal sinuses, detect the changes in the tissues of the eye-ball, optic nerve, and oculomotor muscles, and evaluate the consequences of craniocerebral injuries.

[Role of computerized tomography in the diagnosis of osteomas of the sphenoid sinus with intracranial extension].

The paper reports two rare cases of sphenoidal osteoma which occur statistically in 1.9% of sphenoidal osteomas. Two women underwent computed tomography because of complaints of progressive headaches.

[Late results of the treatment of patients with the extreme degree of alimentary-constitutional obesity by the method of formation of a small stomach].

The work analyses the results of treatment of 311 patients with extreme degrees of alimentary-constitutional obesity by formation of a small stomach. Fatal outcomes (1.9%) were encountered in the period of operative technique mastering.

[Small focal lesions of the stomach].

Small lesions of the stomach in 71 patients are examined roentgenologically, endoscopically and morphologically. The material of 110 gastrobiopsies and 17 stomachs removed because of carcinoma are also studied. The morphological characteristics of small focal stomach lesions (polyps, chronic ulcer, chronic erosions, chronic gastritis, carcinoma) which roentgenologically can be diagnosed only in 62%, is presented.
