The paper is the extension of the author's previous papers and solves more complicated problems. Almost periodic solutions of a certain type of almost periodic linear or quasilinear systems of neutral differential equations are dealt with.
This paper is a continuation of my previous paper in Mathematica Bohemica and solves the same problem but by means of another method. It deals with almost periodic solutions of a certain type of almost periodic systems of differential equations.
We show that whenever the $q$-dimensional Minkowski content of a subset $A\subset \mathbb R^d$ exists and is finite and positive, then the “S-content” defined analogously as the Minkowski content, but with volume replaced by surface area, exists as well and equals the Minkowski content. As a corollary, we obtain the almost sure asymptotic behaviour of the surface area of the Wiener sausage in $\mathbb R^d$, $d\geq 3$.
This study on Alois Klar (1763-1833) focuses mainly on his achievements as a pedagogue and his work for the visually impaired. Methodologically, it draws on Theodor Adorno, Max Horkheimer and Michel Foucault, enabling us to view the evolution of social care as a concomitant of the emerging modern state and integral to its structure. The study presents an analysis of the beginnings of Klar’s Prague institute for the visually impaired against a background of rapid changes in medicine, the scope of the state, and educational thinking. At a time of compulsory school attendance and new approaches to education, when the state demanded the active participation of its subjects/citizens in propagating its aims and the values of society as a whole, the blind and partially sighted were given access to a full and systematic education. We also present data concerning Klar’s educational work and thinking (he taught in Litoměřice and at Prague University), and examine the internal workings of the newly established institute - one of the first of its kind in Europe - and its contacts with the medical discourse of the emerging science of ophthalmology., Marek Fapšo., and Obsahuje bibliografické odkazy
Alois Musil, the Czech Old Testament scholar, priest, topographer and explorer of the unexplored Arabic lands of the Near East before World War I left the scholarly world an immense wealth of information about the Biblical, historical, ethnographical, and archaeological sites he visited, described, noted, and commented on during the years ca. 1896 to 1917. During that time he served as a valuable mediator to the Central Powers (Mittel-Mächte) and the Ottoman Empire seeking to make peace between rival Arab tribes in Arabia. Since he knew the sheikhs of all tribes, and since he was acknowledged by the tribe of the Rualla as sheikh Musa, he was successful in making peace between the tribes of the Rualla, Ibn Rashid, and Ibn Saud. In this way he raised approximately 30,000 camel riders to aid the Ottoman Empire in the fight against the British army in Arabia. Initially his efforts were successful, however due to the shortsightedness of the Ottoman Empire, the British and French military and policy finally triumphed over the tribal confederacies by turning them away from Constantinople. The various episodes of Alois Musil’s sojourn into the Arabian desert, as well as his negotiations with the tribes from November/December 1914 until the middle of April 1915, are described and commented on in this article.
Endothelin-1 (ET-1) acts on ETA and ETB receptors and has been implicated in hemorrhagic shock (shock). We determined effect of shock and resuscitation by hypertonic saline (saline) or centhaquin on ETA and ETB receptor expression. Rats were anesthetized, a pressure catheter was placed in the left femoral artery; blood was withdrawn from the right femoral artery to bring mean arterial pressure (MAP) to 35 mm Hg for 30 min, resuscitation was performed and 90 min later sacrificed to collect samples for biochemical estimations. Resuscitation with centhaquin decreased blood lactate and increased MAP. Protein levels of ETA or ETB receptor were unaltered in the brain, heart, lung and liver following shock or resuscitation. In the abdominal aorta, shock produced an increase (140 %) in ETA expression which was attenuated by saline and centhaquin; ETB expression was unaltered following shock but was increased (79 %) by centhaquin. In renal medulla, ETA expression was unaltered following shock, but was decreased (-61 %) by centhaquin; shock produced a decrease (-34 %) in ETB expression which was completely attenuated by centhaquin and not saline. Shock induced changes in ETA and ETB receptors in the aorta and renal medulla are reversed by centhaquin and may be contributing to its efficacy., S. Briyal, R. Gandhakwala, M. Khan, M. S.

We present new formulae providing equivalent quasi-norms on Lorentz-Karamata spaces. Our results are based on properties of certain averaging operators on the cone of non-negative and non-increasing functions in convenient weighted Lebesgue spaces. We also illustrate connections between our results and mapping properties of such classical operators as the fractional maximal operator and the Riesz potential (and their variants) on the Lorentz-Karamata spaces.
Methods of analyses of biological time series are presented and compared to the traditional techiiiques based on the Fourier transform. Paranietric methods are used for computation of the autoregressive estimator, for the model order selection and for the spectrum estirnation. A nonlinear analysis deals with the state-space trajectory reconstruction and with the fractal and embedding dirnension estirnation. Experimental resiilts compare the abilities of traditional, pararnetric and nonlinear methods to distinguish different cognitive States of the human operator by an analysis of an EEG curve.
