Opis:
The ERTMS system is intended to provide an interoperable approach to train control and signalling in the European Union. The basis for effective train control at ETCS Level 2 is wireless data transmission via GSM-R. This transmission must be protected by cryptographic techniques to ensure its safety. The authors in their article present technical solutions and their applications related to cryptographic keys. They present the requirements that have been formulated for the cryptographic key management system. They discuss its architecture, functions and possibilities of increasing the security of management processes with the use of solutions applied in other branches of the economy. In the last point of the article attention is drawn to the threats posted by the complex process of managing a set of cryptographic keys, the number of which can be measured by tens of thousands.

Opis:
The objective of the study was to evaluate zinc and lead contamination in the upper, organic layer of the soil around zinc and lead smelting plant KGH "Bolesław" in Bukowno near Olkusz. The study material were samples of the upper layer (0-5 cm) of the soil collected at the distance of 10, 25, 50, 100 150, 200, 250 m, and further from each of the 250 m up to 3 000 m sections in 8 directions: N, NE, E, SE, S, SW, W, and NW. The most contaminated soil samples were found at the distance of up to about 1 000 m from the subject plant. The most polluted is the NE and SW area. Pollution of the NE area is related to wind direction. The SW area could be a zinc and lead ore outcrop, or else, it was contaminated when used as a dumping ground for the waste from the plant in the past. Heavy pollution of this area with zinc and lead could cause serious damage to living organisms in the area close to the plant.

Opis:
Magnetic phase diagrams of thulium iron garnets at Τ = 0 K are obtained by means of the so-called Monte Carlo relaxation method. The diagrams are given in terms of the respective strength of the superexchange couplings. There are five different phases and one spin-flop line on the diagram obtained. Two of these phases are of a semi-spin glass type.
