RESUMO

The article is dedicated to the 350th anniversary of the death of the Dutch anatomist, physiologist, yatrochemist and the greatest physician of the XVII century, Franciscus Sylvius (Franz de le Boe) (1614-1672). His contribution to the study of the structure of the nervous system is characterized, as well as the main scientific discoveries and achievements in building a rational system of medical science and practice. It is stated that eponym «aquaeductus Sylvii¼ was coined by Lorenz Heister in 1717 in his paper «De admiranda cerebelli structura¼.

RESUMO

The article provides an overview of foreign and domestic studies on the anatomy of the medial wall of the orbit. Possible structural variants of the osseus structures of the medial wall and their applied clinical significance are indicated, including those having individual occurrence: additional lacrimal bone, morphological features of the structure of the fossa of the lacrimal sac, location, shape and size of the cells of the ethmoid bone, Onody cells, Haller infraorbital cell, the relative position of the anterior and posterior ethmoid foramina, the presence of additional ethmoid foramina, dysgenesis of the lacrimal bone and the orbital plate of the ethmoid bone. The anatomical prerequisites for the occurrence of intraoperative complications with surgical access to the medial wall of the orbit are described.

RESUMO

Polar behaviour in K(1-x)Li(x)TaO(3) ceramics with x = 0:02, 0.05 and 0.10, processed by the conventional solid state method, is studied by Raman spectroscopy and thermally stimulated depolarization current (TSDC) techniques between 10 and 290 K. The TO1 mode of KTaO(3) is revealed to harden in the whole temperature range and to split in the low-temperature range by Li doping. One splitting is observed for x = 0:02 and two consequent splittings are detected for x = 0:05 and 0.10. The temperatures, where TO1 mode splitting occurs, are found to correspond to those of the peaks of TSDC, and hence to the onset of the electric polarization. Such behaviour provides evidence for the order-disorder ferroelectric phase transition induced in KTaO(3) by lithium doping, which emerges from deformations of the cubic phase developed on cooling either in one (for x = 0:02) or two steps (for x = 0:05 and 0.10).

RESUMO

There is presented the experience of surgical treatment of 26 patients with solitary pulmonary metastasesof various malignant tumors. Atypical pulmonary resection wasdone in 5 patients, lobectomy - in 18, pulmonectomy - in 3. After the operation all the patients had survived, complications occur in 5 (19.2%) of them. Complex and combined treatment was performed in 13 (508) patients. Two-year survival rate had constituted 52.9% and three-year one - in 23.5%.

RESUMO

Ceramic Ba(0.6)Sr(0.4)TiO(3) (BST-0.6) samples were studied in the broad spectral range of 10(6)-10(14) Hz by using several dielectric techniques in between 20 and 800 K. The dominant dielectric dispersion mechanism in the paraelectric phase was shown to be of strongly anharmonic soft-phonon origin. The whole soft-mode response in the vicinity of the ferroelectric transition was shown to consist of two coupled overdamped THz excitations, which show classical features of a coupled soft and central mode, known from many ferroelectric crystals with a dynamics near the displacive and order-disorder crossover. Similar behaviour has been recently revealed and theoretically simulated in pure BaTiO(3) (see Ponomareva et al 2008 Phys. Rev. B 77 012102 and Hlinka et al 2008 Phys. Rev. Lett. 101 167402). Also for the BST system, this feature was confirmed by the theory based on molecular dynamics simulations with an effective first-principles Hamiltonian. In all the ferroelectric phases, additional relaxation dispersion appeared in the GHz range, assigned to ferroelectric domain-wall dynamics. The microwave losses were analysed from the point of view of applications. The paraelectric losses above 1 GHz are comparable with those in single crystals and appear to be of intrinsic multi-phonon origin. The ceramic BST system is therefore well suited for applications in the whole microwave range.

RESUMO

By close analogy with multiferroic materials with coexisting long-range electric and magnetic orders a "multiglass" scenario of two different glassy states is observed in Sr(0.98)Mn(0.02)TiO(3) ceramics. Sr-site substituted Mn2+ ions are at the origin of both a polar and a spin glass with glass temperatures T(g) approximately equal to 38 K and < or =34 K, respectively. The structural freezing triggers that of the spins, and both glassy systems show individual memory effects. Thanks to strong spin-phonon interaction within the incipient ferroelectric host crystal SrTiO3, large higher order magnetoelectric coupling occurs between both glass systems.

RESUMO

The creation of silicone endoprosthesis led to new approaches in solving the problems of plastic replacement of the breast after radical mastectomy. Two variants of reconstructive plastic operations with endoprosthetics of the breast were employed: group one--the formation of the seat of the endoprosthesis using a transposed musculocutaneous flap from the latissimus dorsi muscle; group two--the formation of the seat of the endoprosthesis by stretching the skin with a specially designed stretcher-expander and subsequent implantation of the endoprosthesis. The first method is rather injurious, sometimes cannot be performed because of anatomical contraindications, and is fraught with the development of necroses in the transposed tissues. Among 34 patients operated on by the first method two had marginal necrosis of the skin above the endoprosthesis. No complications were recorded among the 46 patients who underwent operation by the second method. The condition of the endoprosthesis and the tissues surrounding it was appraised in the immediate and late periods by radiological and ultrasonic examination. The variants of endoprosthetics of the breast which we applied may be employed with competence in clinical practice, but a reconstructive-plastic operation with the use of a skin expander is preferable.

RESUMO

After the examination and hygienic assessment of 53 types of hand-held Soviet and foreign machines, 30 types of them were selected because according to their vibration and ergonomic characteristics they could be recommended for wide application in automotive industry. Some causes for deterioration of vibration characteristics of hand-held machines while they were in use were analyzed. Among the basic causes there were untimely running, preventive repair and vibration parameters control of the machines and also their mishandling. Introduction of the proposed pattern of machine movement and maintenance during their use could further the improvement of the technical state of hand-held machines and decrease of local vibration levels affecting workers.
