Opis:
The article addresses the semantic relations of Rudkovsky, a modern playwright, with Chekhov’s comedies. The self-consciousness of a person in Chekhov’s drama is directly connected with the historic memory, and this idea is interpreted in Rudkovsky’s works through the theatrical experiment, allowing the actresses to go through war as a personal experience, and for the audience – to set right “the joint” of time.

Opis:
Dynamics of the domain wall between circular magnetic domains in amorphous ferromagnetic $Co_{68.2}Fe_{4.3}Si_{12.5}B_{15}$ wire was studied in a small region around the domain wall equilibrium position in an inhomogeneous magnetic field. The wire was prepared using the in-rotating-water-quenching technique. Small helical anisotropy was induced in the wire by current annealing and simultaneous application of tensile stress and torsion. The inhomogeneous magnetic field acted on domain wall by restoring force directly proportional to the displacement of the domain wall from its equilibrium position. Domain wall position was monitored by circular magnetic flux measurements from which it results that domain wall motion can be modeled by the motion of a very strongly damped pendulum. The value of domain wall mobility obtained from these experiments is in good agreement with the values calculated and measured for domain wall driven by a constant magnetic field.

Opis:
The effect of pressure on the dielectric properties of [NH$\text{}_{2}$(CH$\text{}_{3}$)$\text{}_{2}$]$\text{}_{3}$Sb$\text{}_{2}$Cl$\text{}_{9}$ crystal was analyzed for a few values of hydrostatic pressure within the range from 0.1 MPa to 300 MPa and for temperatures from the range of 220-350 K. The measuring frequency was 1 kHz. The pressure-temperature phase diagram obtained was nonlinear. The temperature dielectric permittivity anomalies related to the paraelectric-ferroelectric phase transition temperature (T$\text{}_{c}$) gradually increase up to 66 MPa and then decrease with subsequent increase in pressure. The character of the temperature dielectric permittivity anomalies, typical of the continuous ferroelectric transition, remains unchanged with increasing pressure. Additionally, the pressure dependences of the Curie-Weiss constants for the crystal in paraelectric (C$\text{}_{+}$) and ferroelectric (C$\text{}_{-}$) phases were evaluated and discussed. The results indicated a complex mechanism of the ferroelectric phase transition.

Opis:
Spectroscopic and magnetic properties of Fe²⁺ (3d⁶; S=2) ions at orthorhombic sites in FeX₂·4H₂O (X = F, Cl, Br, I) crystals are compared with those in [Fe(H₂O)₆](NH₄)₂(SO₄)₂ (FASH). The microscopic spin Hamiltonian modeling utilizing the package MSH/VBA enables prediction of the zero-field splitting parameters and the Zeeman electronic ones. Wide ranges of values of the microscopic parameters, i.e. the spin-orbit (λ), spin-spin (ρ) coupling constants, and the crystal-field (ligand-field) energy levels (Δp_{i}) within the ⁵D multiplet are considered to establish the dependence of the zero-field splitting parameters b_{k}^{q} (in the Stevens notation) and the Zeeman factors g_{i} on λ, ρ, and Δp_{i}. By matching the theoretical spin Hamiltonian parameters and the experimental ones measured by EMR, the suitable values of λ, ρ, and Δp_{i} are determined. The novel aspect is prediction of the fourth-rank zero-field splitting parameters and the ρ (spin-spin)-related contributions, not considered in previous studies. The MSH predictions provide guidance for high-magnetic field and high-frequency EMR measurements.

Opis:
The calculation of the temperature dependence of the domain wall coercivity of ultrathin magnetic films with perpendicular anisotropy is reported. In this case, the magnetization reversal is supposed to occur through domain wall motion. The proposed model takes into account thermal bending fluctuations of the domain wall, which is pinned by crystal defects such as grain boundaries. A fitting procedure, applied to recently published experimental data on the field induced domain wall velocity in Au/Co films, allows us to find out realistic values of the involved parameters.

Opis:
Spontaneous combustion of coal is a phenomenon that often occurs in open coal mining activities, especially strip mining and open pit mining systems which are detrimental to mining companies, the economy, the environment, and society. This phenomenon causes coal mining activities to contribute to CH4 gas emissions in global warming by 11% of total global emission. The purpose of this study was to analyze the role of organic sulfur in the formation of CH4 gas emissions in the spontaneous combustion of coal in the TAL area. The approach is based on a literature review and field survey. The literature review was intended to examine the influence of geological factors, maceral analysis, and depositional environment on the rank and form of coal sulfur, while the field survey was conducted by measuring CH4 gas emissions in 36 samples of spontaneous combustion hotspots. Literature review shows that coal in the TAL area belongs to low rank (sub-bituminous/sub-bituminous B) which has high organic sulfur content in the form of thiother bonds (C-S), especially carbon disulfide (CS2). The average CH4 emission measurement in the field is 6,989 mg/m3, which is still within the limits set by other researchers, between 3,700–34,098 mg/m3. The role of organic sulfur from C–S bonds especially CS2 in the formation of CH4 gas emissions, is very dominant at 93.10% or 6,507 mg/m3 of the total coal sulfur in the TAL area. The emission of CH4 gas in the spontaneous combustion of coal is strongly influenced by geological factors, maceral analysis, and the depositional environment related to the rank and form of coal sulfur. Further, detailed, and comprehensive research on the form of organic sulfur needs to be carried out to mitigate CH4 gas emissions in the spontaneous combustion of coal in the TAL area.

Opis:
By using the complete diagonalization (of energy matrix) method based on the cluster approach (where the admixture between the d orbitals of $d^{n}$ ion and p orbitals of ligands due to covalence effect is considered), the optical and electron paramagnetic resonance data (three optical band positions and four EPR parameters $g_{∥}$, $g_{⊥}$, $A_{∥}$, $A_{⊥}$) are calculated for the tetragonal $Cu^{2+}$ center in $Cu^{2+}$-doped poly vinyl alcohol (PVA) passivated ZnSe nanocrystals with the defect model of $Cu^{2+}$ in the interstitial octahedral site in ZnSe. The calculated results are near the experimental values. The tetragonal elongation of the $Cu^{2+}$ octahedral cluster in ZnSe nanocrystals is obtained. The results are discussed.

Opis:
Two optical bands and four EPR (or spin-Hamiltonian) parameters (g factors $g_{∥}$, $g_{⊥}$ and hyperfine structure constants $A_{∥}$, $A_{⊥}$) of the tetragonally-compressed $Nb^{4+}$ octahedral center in glasses are calculated from two methods, the complete diagonalization (of energy matrix) method and the perturbation theory method. Both methods are founded on the two-spin-orbit-parameter model where both the contribution to the spectral data from the spin-orbit parameter of central $d^{n}$ ion and that of ligand ion via covalence effect are considered. The calculated results from both the complete diagonalization (of energy matrix) method and perturbation theory method show reasonable agreement with the experimental values. The signs and possible misprint for the observed hyperfine structure constants $A_{∥}$ and $A_{⊥}$ are suggested, and the local structure of the tetragonal $Nb^{4+}$ center in glasses due to the Jahn-Teller effect is gained from the calculations. The results are discussed.

Dielectric relaxation study of nematogenic 4-n-alkyl-4'-cyanobiphenyls (nCB, n = 5, 6), 4-(trans-4'-n-alkylcyclohexyl)isothiocyanatobenzenes (nCHBT, n = 6, 8), 4-cyanophenyl-4'-n-alkylbenzoates (nCPB, n = 6, 8), 4-cyano-3-fluorophenyl-4'-n-octyloxybenzoate (8OCFPB), and 4-cyanophenyl-4'-n-octyloxy-3'-fluorobenzoate (8OCPFB) was performed in the frequency range from 50 kHz to 100 MHz in the nematic and isotropic phases. The static permittivity and the relaxation process related to the rotation of molecules around their short axis was analyzed. For some of these liquid crystals anomalous temperature dependence of static permittivity in the pretransitional region of the isotropic phase was observed. Based on the Meier-Saupe-Martin model of molecular diffusion in nematics, the orientational order parameter 〈$P_2$〉 was determined from dielectric relaxation times and retardation factor. The values of 〈$P_2$〉 calculated from the dielectric relaxation data were compared with the results obtained from measurements of polarized electronic absorption. Correlations between the magnitude of the dielectric pretransitional effect and the orientational order in the nematic phase were discussed.

Opis:
Currently, organic halogen compounds (halogen derivatives) are often identified in water. The paper presents the problem of the presence of these newly formed compounds during water treatment processes and their occurrence in sewage. The general indicator determining the content of these compounds in aqueous solutions is the concentration of halogen derivatives of organic compounds adsorbed on activated carbon AOX, which is converted to the concentration of chlorides. The groups of derivatives of halogenated organic compounds containing chlorine and/or bromine in a molecule were characterized, and the precursors and potential for the formation of these compounds in water were described. Moreover, technological methods to prevent and remove them were described.

Von 1981 bis zur sogenannten Wende 1989 (und sogar einige Jahre darüber hinaus) veröffentlichten der Verlag C.H. Beck in München und die Verlagsgruppe Kiepenheuer in Leipzig gemeinsam die Bibliothek des 18. Jahrhunderts. Die Reihe war eines der großen, auf langfristige Zusammenarbeit angelegten Unternehmen zweier Verlage im geteilten Deutschland. Mehr als 40 zum Teil mehrbändige Werke konnten in ihr erscheinen. Der hier vorgelegte Bericht versucht, die Bedingungen der damaligen Kooperation zu rekonstruieren und darüber hinaus etwas von der Atmosphäre zu vermitteln, in der die gemeinsame Arbeit stattfand.
Od roku 1981 do tzw. Przełomu w 1989 (a nawet kilka lat dłużej) wydawnictwa C.H. Beck z Monachium oraz Kiepenheuer z Lipska publikowały wspólnie Bibliothek des 18. Jahrhunderts [Biblioteka XVIII wieku]. Seria ta była jednym z największych, długofalowych przedsięwzięć dwóch wydawnictw w podzielonych Niemczech. W serii tej ukazało się ponad 40, głównie wielotomowych, dzieł. Przedstawiona relacja jest próbą rekonstrukcji warunków ówczesnej współpracy obu wydawnictw oraz towarzyszącej jej atmosfery.
From 1981 until the Fall of the Berlin Wall in 1989 (and even several years beyond) the publishing houses C.H. Beck in Munich and Kiepenheuer in Leipzig issued jointly Bibliothek des 18. Jahrhunderts [Library of the 18th Century]. This series was one of the big projects planned for a long-lasting cooperation between two publishers in divided Germany. More than forty works of literature, some of them in several volumes, were issued within the scope of this ,Library‘. The present report is an attempt at reconstructing the conditions of cooperation during that period and to convey something of its atmosphere.
