legal position and role of the voivode in ‘People’s Poland’
Opis:
The article considers the legal status of the voivode in post-war Poland ruined by the Nazi occupation, deprived of its own administrative apparatus (from 1939) and the construction of this position from scratch under new rules dictated by Moscow (from 1944).This periodisation was not matched by the ability to preserve Poland’s administrative apparatus. In occupied Poland, this function was not fulfilled by the highest Polish authorities in exile and their expatriate branches in the country. This opened the way for Moscow (strengthened by an amenable attitude from the Allies) to build the ‘People’s Poland’ (1) with an apparatus of supreme power (in the period before and after the enactment of the February Constitution) and (2) local, decentralised power (from 1944 based on national councils, and until 1950, also based in general administrative bodies – voivodes, starosts and local government administration).The author refers to both spheres of legal activity in the process of constructing this administrative apparatus. In chronological order, she discusses the basic legal acts enacted by the supreme authorities of the time. She focuses her attention primarily on acts directly concerning local administration, with particular emphasis on the institution of the voivode, which from 1944 was incorporated into the system of national councils, following the example of ‘people’s’ states.This analysis enables the conclusion to be drawn that the legal conditions at the time changed the legal status of the voivode, who was nominated by the government (and thus not the head of state). Appointing the voivode required an opinion from the competent national council. The council was empowered with the right of social control over the activities of the voivode. In practice, the influence of the voivodeship national council on the activities of the voivode was weak. The voivode was still the main element in the organisational system of the state’s local administrative apparatus as the representative of the government at the local level, the head of the general (composite) administration and the chairman of the executive body of the local government. The voivode’s competences excluded that of supervising local government bodies. In the years 1945–1949, a different status applied to the governors of the Recovered Territories.

Opis:
Extreme ultraviolet (EUV) covers wavelength range from about 5 nm to 50 nm. That is why EUV is especially applicable for imaging and patterning on nanometer scale length. In the paper periodic nanopatterning realized by interference lithography and high resolution holographic nanoimaging performed in a Gabor in-line scheme are presented. In the experiments a compact table top EUV laser was used. Preliminary studies on using a laser plasma EUV source for nanoimaging are presented as well.

In the article the cooperative $N^2$-effect is considered, that is the radiation whose power is ım $N^2$, where N is the number of emitters which in this case is equal to the number of electrons in a bunch. The suggested effect is the result of combining two other effects, Gunn-effect in GaAs and undulator-like radiation which can be produced by means of microstructure with grating (microundulator). It is very probable that the effect can be used for the developing of a new semiconductor-based room temperature source of the THz radiation.

The suggested effects are the result of combining two effects: the Gunn-effect in GaAs and undulator-like radiation, or "pumping wave" acting on the electrons and which is the result of undulator field, while the second is the backward effect of radiation which is produced by electrons moving within such microundulator. It is very probable that the effects can be used for the developing of a new semiconductor-based room temperature source of the THz-radiation.

Opis:
Calcium fluoride crystals doped with various concentrations of $PbF_{2}$ have been grown using the Bridgman technique. The optical absorption spectra reveal the characteristic UV absorption bands of the $Pb^{2+}$ ions. The distribution of the $Pb^{2+}$-ions along four crystals has been investigated using the optical absorption method. Taking into account the relationship between the optical absorption coefficient and the concentration of the impurities in the samples, the effective segregation coefficient of the $Pb^{2+}$ ions has been calculated. Our study shows that the effective segregation coefficient of the $Pb^{2+}$ ions in $CaF_{2}$ host depends on the dopant concentration, and varies between 0.85 and 1.15, for 0.5 mol%$PbF_{2}$ and 3 mol%$PbF_{2}$-doped $CaF_{2}$, respectively.

Opis:
Polymerization contraction of dental photo-polymer composites induces internal stress, in a tooth cavity. This stress is measured indirectly by, first, holographic determination of tooth deformation, with consequent calculation of stress using finite element method. Real time holographic technique enabled observation of dental deformation in all stages of polymerization. Specially constructed blue-LED light source was used to polymerize photopolymer composite. We have found that polymerization continues even after illumination is over. Consequently, stress is increased, too.

Opis:
This is an analysis of the epigram On the Old Man (II.42), Jan Kochanowski's single epigram (fraszka) on a medical theme. The old man of the title suffers from priapism, i.e. an abnormal persistent erection. Part I of the article discusses the significance of the poem's place in the sequence of epigrams that make up the collection and its intertextual links to earlier literature referring to the phallic god Priapus, especially Martial's Epigrams. In Part II it is argued that Kochanowski's understanding of priapism and its underlying causes was based on humoral medicine and detailed descriptions of this condition in Renaissance (primarily Italian) medical manuals. An analysis of the poem from the medical perspective leads to the conclusion that Kochanowski's bawdy conceit contains a misrepresentation: what for humoral medicine was a possible anomaly (priapism in old men) became a well-documented condition.

Opis:
Integrating photon collection on position sensitive detectors used in combination with an absorption filter offers many advantages in X-ray fluorescence holography experiments: (i) the simultaneous recording of the full hologram allows us to overcome most of the difficulties - notably the large number of experimental points and the precision requirements - that make the practical realization of the measurement of holographic patterns very difficult and time demanding also when using powerful synchrotron radiation sources; (ii) the high angular resolution and the very precise detection of intensities make the reconstruction of images of distant as well as light atoms possible; (iii) area detectors are readily available at most crystallography dedicated beamlines at synchrotron radiation sources, so there is no need of complex, dedicated instrumentation. As an example, the hologram of a CoO single crystal recorded on an imaging plate is reported, evidencing the images of atoms located up to more than 7Å far from the emitter and also of the light oxygen atoms.

Opis:
We show that bistability and metastability of In and Ga impurities in CdF$\text{}_{2}$ crystals can be efficiently used in writing volume holographic gratings. Phototransformation of these impurities from the localized to the hydrogenic state leads to a large change of the local polarizability of the host, and thus a significant change of the refractive index. While CdF2:In can be used only at low temperatures (below 150 K), CdF2:Ga crystals are suitable for room temperature recording.

Opis:
Oxyhalides of bismuth BiOX (X = Cl, Br, I) are very interesting materials which find various applications as X-ray luminescent screens, as anti-Stokes converters, photocatalyst, usual luminophors and as photoconductive analyzer of linear polarized radiation in the 0.24 - 1.2 μm spectral region. The great interest for these materials is strongly related to the influence of dimensionality on the behaviour of physical properties (they are 2D structured materials). Bismuth oxyhalides are one of the V-VI-VII group compound semiconductors belonging to the tetragonal system. The structure of BiOX is known to have a layered structure, which is constructed by the combination of the halide ion layer and the bismuth oxygen layer. We present results of the study of photoconductivity spectra anisotropy of the BiOX single crystals.

Opis:
PbWO₄ crystal-Hamamatsu S8148 avalanche photodiode (APD) assembly has been used in the barrel section of the CMS electromagnetic calorimeter. The shot noise of the photodiode is one of the important parameters for the energy resolution of the crystal-APD system. The major source of this noise is the statistical variations in the rate at which primary charge carriers are generated and recombine. Thus, the shot noise varies with position of the primary charge carriers generated in photodiode. In this work, the shot noise properties of the Hamamatsu S8148 APD structure and zinc sulfide-silicon (ZnS-Si) isotype heterojunction APD structure have been compared for the PbWO₄ photons. Calculations were made with a Single Particle Monte Carlo simulation technique.
