Opis:
The pretransitional phenomena of superprotonic phase transition (T$\text{}_{sp}$=471 K) were studied in detail by X-band continuous wave EPR spectra of K$\text{}_{3}$H(SO$\text{}_{4}$)$\text{}_{2}$ crystal doped with VO$\text{}^{2+}$ ions. Three kinds of VO$\text{}^{2+}$ complexes (magnetically equivalent but structurally non-equivalent) denoted as VO$\text{}^{2+}$(I), VO$\text{}^{2+}$(II), and VO$\text{}^{2+}$(III) were found. "Smearing out" of the superhyperfine structure was observed as a result of interbond proton motion. VO$\text{}^{2+}$ impurity replaces K$\text{}^{+}$ ion and experiences the same average crystal field gradient at T$\text{}_{sp}$=471 K for I- and II-type complexes. The increase in interbond proton frequency hopping above 360 K is a reason of significant line broadening.

Opis:
The K$\text{}_{3}$H(SO$\text{}_{4}$)$\text{}_{2}$ doped with Cu$\text{}^{2+}$ ion was studied in detail by X-band CW EPR. Two kinds of Cu$\text{}^{2+}$ complexes (magnetically and structurally nonequivalent) denoted as Cu$\text{}^{2+}$(I) and Cu$\text{}^{2+}$(II) were found. Spin-Hamiltonian parameters, direction cosines, and coordination of Cu$\text{}^{2+}$ ion were determined at room temperature. The superhyperfine structure was observed below 250 K as a result of interacting of Cu$\text{}^{2+}$ ion with four equivalent protons (I=1/2). Temperature studies of K$\text{}_{3}$H(SO$\text{}_{4}$)$\text{}_{2}$ crystal show that interbond motion as a precursor of superprotonic phase transition occurs at above≈250 K.

Opis:
In this paper we present recent experimental results related to nonlinear crystal field fluctuations and current flow in K$\text{}_{3}$H(SO$\text{}_{4}$)$\text{}_{2}$ fast-proton conductor far below the transition temperature T$\text{}_{g}$. The results for crystalline and powdered samples are quantitatively explained in the framework of soliton model of charge transport.

ART HISTORY
GASIOROWSKI
Opis:
Stanisław Jan Gasiorowski (1897-1962) studied classical archaeology and art history at the Jagiellonian University during the years 1915 -1920, under direction of Piotr Bienkowski and Julian Pagaczewski. During a one-year stay in Vienna, he attended lectures given by Joseph Strzygowski, Max Dvorak and Julius Schlosser. In 1922, he started his professional career as an assistant in the Chair of Classical Archaeology at the Jagiellonian University. In 1930 he was named professor extraordinarius and in 1937 ordinarius. He remained in this position until 1953. In November of 1939, along with other professors of the Jagiellonian University, he was arrested by the Nazis, and imprisoned in the Sachsenhausen concentration camp. In 1942 the Prince Czartoryski family entrusted him with the position of director of the Czartoryski Museum. In 1951 Gasiorowski was dismissed, under the pretext that he was in the service of “aristocratic and bourgeois enemies of the Polish people”. Shortly thereafter the authorities also forced his removal from the University (1953). Deprived of the opportunity to give lectures and be in contact with students, he shifted his work to the Institute of Material Culture of the Polish Academy of Science, and remained there until his death. His research interests followed three general themes. The first of these was ancient art in the strict sense. He was the author of Poland’s first summary of the history of ancient art. The second area involved the theoretical foundations for the study of the material culture of Mediterranean countries. Finally, the third area was the publication of ancient and modern artworks from Polish collections as well as their history, and information on early Polish travelers to the Mediterranean countries

Opis:
Cadmium pyroniobiate (CNO) is the ferroic material with unusual diffuse phase diagram which includes both relaxor and nanocluster domains. We present the data for CNO crystals with several admixtures of paramagnetic ions studied on X and S microwave bands at zero-external magnetic field and classical EPR conditions. Our results lead to an assertion of a ferroelectric resonance effect due to "electronic ferroelectricity". The data fit well to the Falicov-Kimball theoretical model applicable to strongly-correlated-electron or mixed-valence systems.

Opis:
The paper reports the electron paramagnetic resonance investigation of Cu$\text{}^{2+}$ doped [(CH$\text{}_{3}$)$\text{}_{2}$NH$\text{}_{2}$]$\text{}_{5}$Cd$\text{}_{3}$Cl$\text{}_{11}$ (DMACC) monocrystal. DMACC:Cu$\text{}^{2+}$ was studied in the temperature range (6÷293) K. We did not observe any anomalies of spin-Hamiltonian parameters of Cu$\text{}^{2+}$ ion corresponding to the temperature anomalies observed in dielectric studies. The electron paramagnetic resonance anomaly recorded at about 40 K results from the subtle changes in bonds angles and Cu-Cl distances and suggests the smooth second order transition.

Opis:
Purpose: The main purpose of this study to analyze the coordination, propulsion and non-propulsion phases in the 100 meters breaststroke race. Methods: Twenty-seven male swimmers (15.7±1.98 years old) with the total body length (TBL) of 247.0±10.60 [cm] performed an all-out 100m breaststroke bout. The bouts were recorded with an underwater camera installed on a portable trolley. The swimming kinematic parameters, stroke rate (SR) and stroke length (SL), as well as the coordination indices based on propulsive or non-propulsive movement phases of the arms and legs were distinguished. Results: Swimming speed (V 100surface breast ) was associated with SL (R=0.41, p<0.05) and with TBL tending towards statistical significance (R=0.36, p<0.07), all relationships between the selected variables in the study were measured using partial correlations with controlled age. SL interplayed negatively with the limbs propulsive phase Overlap indicator (R=-0.46, p<0.05), but has no significant relationship to the non-propulsion Glide indicator. Conclusions: The propulsion in-sweep (AP3) phase of arms and their non-propulsion partial air recovery (ARair) phase interplayed with V 100surface breast (R=0.51, p<0.05 and 0.48 p<0.05) respectively, displaying the importance of proper execution of this phase (AP3) and in reducing the resistance recovery phases in consecutive ones.

Purpose: Maintaining balance in humans involves continuous changes in parameters. The aim of this study was to assess the effect of hippotherapeutic exercises on development of the sense of balance in boys aged 15 to 17 years with mild intellectual disability. Methods: The study examined 50 randomly chosen boys aged 15 to 17 years with mild intellectual disability from the special education centre in Leżajsk, Poland. The study participants were divided into two groups: experimental group, who participated for 3 months in hippotherapeutic classes and the control group, with boys attending outdoor or indoor physical education classes. Before and after completion of the study, both experimental and control groups were diagnosed by means of Accu SwayPlus force plate. The force plate was used to determine alterations in the position of the centre of pressure (COP) on the platform in the frontal and sagittal planes in relaxed standing position with feet spread to the shoulder width and with eye control with respect to the base of support (BOS). The description was based on mean displacement of the centre of gravity (COG), mean velocity of displacements of the COG, mean radial displacement and total length of the COP pathway. Results: In the experimental group, equestrian exercises induced a series of significant changes that pointed to the improved balance reactions. The character of these changes in the positions analysed was similar: values of body sway in the sagittal plane and their range and mean displacements decreased statistically significantly after training. The same tendency was observed for mean radial displacements in the free open position and with closed support surface. Furthermore, the velocity of displacement and the length of the COP’s projection pathway on the support surface in the free open position was also reduced. All significant changes and trends found for the experimental group, which occurred after 3 month of hippotherapeutic classes, suggest improved parameters of balance. Conclusions: The lack of changes in balance parameters in the control group shows that the hippotherapeutic classes significantly develop balance abilities in boys aged 15 to 17 years with mild intellectual disability.
