Optimism Experiment and Development of Space-qualified Seismometers in France

The OPTIMISM experiment will put two magnetometers and two seismometers on the Martian floor in 1995, within the framework of the Mars '94 mission. The seismometers are put within the two small surface stations. The seismometer sensitivity will be better than 10 exp -9 g at 1 Hz, 2 orders of magnitude higher than the Viking seismometer sensitivity. A priori waveform modeling for seismic signals on Mars shows that it will be sufficient to detect quakes with a seismic moment greater than 10 exp 15 Nm everywhere on Mars. Such events, according to the hypothesis of a thermoelastic cooling of the Martian lithosphere, are expected to occur at a rate close to one per week and may therefore be observed within the l-year lifetime of the experiment. Other aspects of the experiment are discussed

Development of a CFD model for propeller simulation.

The article presents a development of numerical model for a single propeller simulation and comparison of obtained results with experimental data available from a test campaign in scale 1:1. Described simulation is a steady state computation taking advantage of Multiple Reference Frame model implemented in Ansys CFX. The paper includes an analysis of rotating domain thickness influence on numerical values of thrust and power. The results indicate that this type of simulation may be sensitive to the sizing of rotating domain especially when disc solidity is low, or when the number of blades is 2, a frequent situation in all electric flight vehicles. The analysis shows that performing simulations, using one domain sizing, for a number of flight scenarios requiring analysis of a few rotational speeds can produce unintuitive results. Therefore, it is suggested to calibrate the model, preferably by experimental results

Czy politologia to „nauka interdyscyplinarna”? Kilka słów o przedmiocie poznania i tożsamości dyscypliny

The article provides a short and synthetic analysis about condition of political science in Poland. It is a voice in the debate about the subject of cognition in the discipline. The article focuses on the problem of interdisciplinarity in political science. Author argues that the lack of reflection on the subject of discipline knowledge leads to the impoverishment of its achievements

Wielka Gra” na Oceanie Indyjskim. Chiny, Indie i Stany Zjednoczone w regionalnej rywalizacji mocarstw

The Indian Ocean constitutes an area which is rich in resources and vital to shipping. In this region there are some strategic sealines that enable communication of China and India with this resourceful area. Due to the fact that the Indian Ocean region is rich in oil, China and India seek dominance in this part of the world. The article explains and describes the dynamic of greatpower rivalry in various aspects. It also analyzes the role of the Unites States as stabilizing power in the new political and economic environment in Asia
