Opis:
The period of German reunification was a very turbulent time for the Green Party. Plagued by internal conflicts and wrong decisions made during the campaign, it seemed to have come to a standstill, letting its competitors overtake it. Why did the Greens fail to take advantage of the period of German reunification, and why did the party’s East German roots have such a huge impact on its subsequent actions in the political arena? The internal war over the ideology that should guide the party in the future and the clarification of the concepts that defined the Green Party’s identity coincided with the most difficult election campaign since the party was founded. The following article touches on intra-party conflicts, the evolution of the Greens’ demands, the ifluence of key figures in shaping party strategy during the period of German reunification and relations between party branches on both sides of the Berlin Wall. It also discusses the situation of the Green Party in East Germany and West Germany before and just after reunification (i.e. after the first Bundestag elections after reunification).

W niniejszym artykule podjęta została problematyka powstania i rozwoju budownictwa wielkopłytowego w odniesieniu do argumentów ideologicznych. Ten splot uwarunkowań sprawił, że przetrwało ono blisko cztery dziesięciolecia. W niektórych krajach wielka płyta stała się wręcz ikoną nowoczesnego mieszkalnictwa. Wszystko to pozwala nam dziś spojrzeć na nią nie tylko w świetle niedoskonałego pod względem architektonicznym tworzywa.
This article brings up problems of raising and development of panel housing in reference to ideological arguments. Such coincidence caused, that it has been lasting for 40 years. In some countries panel housing has become an icon of modern housing. Today we can look at these problems not only in the light of architecturally imperfect fabric.

Opis:
We published the first description of a disk-shaped MHD aerodyne, combining pulsed ionization and induction systems. Magnetic pressure tends to push away electric discharge, in region of low magnetic field. In the seventies the efficiency of the wall confinement, due to the inversion of the magnetic pressure gradient was demonstrated. It is time now for ambitious MHD projects. We have planned experimental studies of MHD acceleration, combining pulsed ionization, wall confinement and induction system. We intend to study pulsed ionization systems based on wall micro discharges or microwaves action. We present the different features of the project.

Opis:
When a plasma is subjected to a transversal magnetic field and its Hall parameter is non-negligible, it weakens the local electric conductivity value. If an electric discharge is created near a wall and the magnetic field decreases with distance, the electric discharge will follow a path that minimises the streamer's electric resistance, which could expel it far from the wall. One solution to ensure that it remains up against the wall is by inversion of the magnetic field's gradient by arranging that field B be minimal at the wall. In the experiment we are presenting, effected in a low-density gas, in order to obtain a high value for the Hall parameter using simple permanent magnets, we will show the remarkable efficiency of this parietal confinement method and present the main lines of the programme of which this experiment forms part and whose successful realization will be the demonstration of the feasibility of the displacement of disk-shaped MHD aerodynes at supersonic speed without creating either shock waves or turbulence, an approach that we have already set out in numerous publications.

Opis:
The detailed magneto-electron-lattice (vibronic) theory of ferroelectricity in the Bi-based multiferroics (BiFeO₃ etc.) is developed further. The vibronic admixture of the empty oxygen 2p states to the Bi 6s lone electron pair state leads to ferroelectricity. These interactions are the driving and restoring forces of the structural phase transformations of the Bi-based multiferroics. The free energy of the BiFeO₃-type multiferroics with the ferroelectric and the G-type antiferromagnetic phase transitions are derived. The Zeeman splitting and spin-transversal optical phonon couplings are also important.

Opis:
Data processing algorithms are important parts of modern measurement systems. These algorithms are often delivered to the user as complex program and their numerical structure is not known. Therefore also influence of algorithm on processed data accuracy is not known. One of the methods to evaluate uncertainty propagation through algorithm is based on matrix form of algorithm. Coefficient matrix of algorithm represents its numerical operations and it is a basis to algorithm accuracy evaluation. The paper presents a method how to identify this coefficient matrix when algebraic form of the algorithm is known or is difficult to use. Identified matrix form of algorithm is then used to estimate uncertainty propagation through exemplary algorithms. Results are compared with experiments.

Opis:
Angular distributions of very high energy photoelectrons from Xe and Kr, excited by a 50 ps, 1054 um laser, are presented. In Xe strong, narrow structures 45° off the polarization axis appear on above-threshold ionization peaks within a limited energy range centered around 9U$\text{}_{P}$, where U$\text{}_{P}$ is the intensity-dependent ponderomotive energy. Under the same conditions the effect is much weaker in krypton. These structures are discussed using a very simple classical model as well as sophisticated single active electron calculations and the Keldysh-Faisal-Reiss theory. We conclude these structures are the result of single-electron dynamics involving rescattering of a tunneling component of the continuum wave function.

Opis:
Understanding of biological function requires knowledge both on structural and dynamical aspects. The aim of time-resolved X-ray diffraction is to combine structural and kinetic methods by monitoring structural or conformational changes within a single protein or assemblies of proteins during their biological action in real time. This requires (i) a powerful X-ray source, (ii) appropriate detectors capable of dealing with high local and total count rates and (iii) a suitable trigger mechanism. These aspects are briefly discussed with emphasis on light as trigger for initiation of structural or conformational changes. Examples are presented on muscle contraction, lipid phase transitions, the photocycle of bacteriorhodopsin and the application of Laue crystallography on the protein p21.

Opis:
Recently, there has been observed intensified research on the impact of income inequalities on aspects of socio-economic development in the European Union. However, there are no comprehensive analyses concerning the relationship between these phenomena. Therefore the subject of the paper is the influence of income inequalities on socio-economic development. The author would like to verify the hypothesis that the character of the impact of income inequalities on socioeconomic development in the European Union is negative. Analysis was conducted for the European Union in 2004-2017 using the panel data model, also estimated was the synthetic indicator of socioeconomic development. The research conducted in the paper leads to ambiguous conclusions. On the one hand, inequalities measured for the whole distribution of income have no influence on socioeconomic development in the European Union. However, the income gap between the richest and the poorest hinders the mentioned phenomenon.

Opis:
The $PbFe_{1//2}Nb_{1//2}O_3$ (PFN) ceramics can be obtained by a lot of ways. There are a lot of methods and techniques to synthesize the PFN powder such as: reactions in the solid phase by one-stage or two-stage synthesizing method (the columbite method), molten salt synthesis, sol-gel, co-precipitation method and sintering of compacts from a loose mixture of powders. Each of them requires accuracy and precision to conduct a technological process, aiming at obtaining a product with the optimum parameters. In the work PFN specimens were obtained by one-stage synthesis methods using two different powder synthesizing techniques: by calcining (sintering of a loose mixture of the PFN powder) and as a result of sintering of pressed compacts from the PFN powder mixture at high temperature (pressing). The obtained specimens were subjected to X-ray and micro-structural examinations and tests of internal friction and dielectric properties. The tests showed that the ceramics obtained by the powder calcining method has better applied properties.

Opis:
Investigation results of acoustic emission signals coming from partial discharges within chosen generator coil bar, in relation to measurement results of apparent charge introduced by partial discharges sources, are presented in the article. Analysis is based on amplitude distributions calculated for acoustic emission signals, ordered at different measuring points for different values of the supply voltage. In order to assign acoustic emission signal to its advance degree a descriptor named by an acronym ADP (defined by authors) is calculated for each amplitude distribution. Descriptor families describing acoustic emission signals measured at particular measuring points (for different supply voltages) are presented in relation to apparent charge introduced by acoustic emission sources. These families concerning acoustic emission signals, measured at different measuring points for identical supply voltage, enable us to locate acoustic emission sources with maximum activity.

Opis:
With the aim of studying the characteristics of laser-triggered surface flashover in voltage pulse, synchronization problem of laser pulse and voltage pulse should be solved. A single/double harmonic, with wavelength λ of 1064/532 nm, Q-switched Nd:YAG laser is used to trigger the surface flashover. The synchronization problem is solved using a self-made digital delay/pulse generator. The delay time and jitter of Marx's trigger input and output, Marx's trigger output and Marx's output, laser input and output are respectively measured. Based on the result of the delay time and the timing sequence of the laser triggering system, the synchronization of laser pulse and voltage pulse is obtained through adjusting the channel delay time of digital delay/pulse generator. In addition, introductory experiment of laser-triggered surface flashover is carried out using the flat electrodes and columned insulators.

Opis:
The article describes the SUEZ- a former system of the disclosure and recording of data on mineral resources deposits in Poland (the name has been used since 1977), which was started in 1974 to collect and process information on mineral deposits. Its founder was the Research and Development Center for Geologic Technology (OBRTG) in Warsaw, which was subordinate to the Central Geology Office (CUG). The system was running on a 16 bit Eclipse C/300 (Data General, USA) third-generation computer The collected information was used by administration, companies and research centres. In 1976-1989, SUEZ was used to calculate and compile data for the balance of mineral resources in Poland. At the end of the 1980s, these tasks were taken over by the MIDAS computer system (MIDAS System of management and protection of mineral resources in Poland, PIG-PIB Warsaw). The history of the SUEZ system is presented, the computer hardware on which it worked, the system architecture and the methodology for data collection are characterised. The article discribles its functions and application.
