At present, there are insufficient information about baroreflex sensitivity (BRS) and factors that determine BRS in premature newborns. The objective of this study was to determine the relationship between BRS and the characteristics that reflecting the intrauterine development (gestational age and birth weight), as well as postnatal development (postconception age and the actual weight of the child at the time of measurement). We examined 57 premature infants, who were divided into groups according to gestational age and postconception age as well as birth weight, and weight at the time of measurement. Continuous and noninvasive registration of peripheral blood pressure (BP) was perf ormed in every child within 2-5 m in under standard conditions using a Portapres (FMS) device. The results showed a close correlation of baroreflex sensitivity, heart rate and respiratory rate with gestational age, postconception age, birth weight and actual weight at the time of measureme nt premature newborns. An increase in the characteristics (ages and weights) resulted in increased BRS and diastolic arterial pressure (DAP), and in decreased heart and respiratory rates. Baroreflex sensitivity in the first week was in the group of very premature newborns the lowest (4.11 ms/mmHg) and in the light premature newborns was almost double (8.12 ms/mmHg). BRS increases gradually in relation to postnatal (chronological) and to postconception age as well as to birth and actual weight. The multifact or analysis of BRS identified birth weight and postconception age as the best BRS predictors. The two independent variables together explained 40 % of interindividual BRS variability., K. Haskova, M. Javorka, B. Czippelova, M. Zibolen, K. Javorka., and Obsahuje bibliografii
We study G-almost geodesic mappings of the second type \mathop {{\pi _2}}\limits_\theta (e),\theta = 1,2 between non-symmetric affine connection spaces. These mappings are a generalization of the second type almost geodesic mappings defined by N. S. Sinyukov (1979). We investigate a special type of these mappings in this paper. We also consider e-structures that generate mappings of type \mathop {{\pi _2}}\limits_\theta (e),\theta = 1,2. For a mapping \mathop {{\pi _2}}\limits_\theta (e,F),\theta = 1,2 we determine the basic equations which generate them., Mića S. Stanković, Milan L. Zlatanović, Nenad O.

The objective of this paper is to examine the drafting of the decrees that governed relations between the Hussites and the Roman Church after the Council of Basel; and, subsequently to answer the following question: what exactly did the decrees include and what did they comprise of? As all available information indicates, the basic body of the so called Compactata of Basel comprised of eight documents. In addition to the Compactata of Basel, the so called Imperial Compactata are referred to in literary sources; these decrees include five of Sigismund’s documents that were issued prior to his accession to the Czech throne. and František Šmahel.
