Abstract

Issues of communication, isolation, and education are part of our everyday lives, whether private or professional. The behaviour of the young generation at school and at home has different forms. It demonstrates their actions, way of thinking and feeling. Furthermore, their behaviour expresses their future tendencies. These forms of behaviour are strongly influenced by a lack of communication. As a result, the educational process is made harder, sometimes even impossible. Many experts in ethics, pedagogy and psychology have been paying attention to this issue and have started to evaluate its impact on the young.

Abstract

In the work, evaluation of agricultural production space of the area at the Węglowa street in Jastrzębie Zdrój is presented. The method of the synthetic indicator proposed at the Institute of Soil Science and Plant Cultivation in Puławy was used in the calculation. The determined synthetic indicator of agricultural production space of the investigated area classifies it as the area of mean conditions for agricultural production. Geomechanical and hydrological degradation of soil increasing in time may cause changes of values of this indicator and also high deterioration of environmental conditions of agricultural production.

Abstract

The article deals with the active control of oscillation patterns in nonlinear dynamical systems and its possible use. The purpose of the research is to prove the possibility of oscillations frequency control based on a change of value of singular perturbation parameter placed into a mathematical model of a nonlinear dynamical system at the highest derivative. This parameter is in singular perturbation theory often called small parameter, as ε → 0+. Oscillation frequency change caused by a different value of the parameter is verified by modelling the system in MATLAB.

Analysis of the Influence of Carried Out Repairs Efficiency on Transport Means Operational Reliability

The Maintenance factors and destructive processes which affect systems and elements of technical objects result in undesirable changes of values of their functional features, which causes damages. A damage to a technical object has been defined as exceeding permitted boundary values by significant features characterizing their elements. On the basis of analysis results of the author's own research concerning damages to means of transport, used in real transport systems, it has been found that these damages are the effect of different forcing factors. A certain number of damages is caused by natural wear of machine elements, whereas other damages can occur in result of ineffective repair of a previous damage. Thus, the so called recurrent (secondary) damages occur in a short period of time. On the basis of literature and maintenance and operation analysis results it was found that the most frequent cause of recurrent damage occurrence is improper quality of repairs of the analyzed means of transport. Primary damages are not dependent on each other and they appear randomly, whereas recurrent damages do depend on each other and their occurrence is the conditioned by earlier occurrence of a repair, and above all, by its poor quality. In the paper, a method for evaluation the influence of carried out repairs on transport means operational reliability, has been presented On the basis of the analysis of the moments in which damages to the means of transport and of the time interval lengths between them a simulation model representing a real stream of the damages was built, which enables to evaluate influence of the efficiency of the performed repairs of the means of transport in the real transport system

test. The minimum stress ( q ) increased to ~0.1 MPa and oscillated around this value during the following period of monitoring. Basically, the tilt angle (θ) of the maximum stress ( p ) from the vertical decreased during the entire monitoring period. At the very moment when the lowest values of the minimum stress ( q ) and the maximum stress ( p ) were recorded, the angle also reached the minimal value of ~15°. Hence, it may be argued that in this period, the maximal main stresses were only insignificantly deviated from the vertical. Figure 8 Change of values and

N A L Y S I S OF D E P O S I T S IN V I S T U L A 43 in the Pleistocene and Holocene terrace has not shown any essential differences. In both cases the structure of curves is multimodal and much the same (Fig. 4). Instead, we can observe a considerable change of values of granulation indices calculated after R. L. Folk and W. C. Ward's formulas (1957) for the deposits of the Pleistocene terrace (boring n° 4) and the deposits of the Holocene terrace (boring n° 5). In the Pleistocene deposits great differences of granulation features in the vertical profile

elaboration of the forecasts for the changes in the climate of Europe (inclu- ding Poland) in the 21st century, according to the interference of climatic cycles. A novelty is constituted by the new type of forecasts for the 21st century, based upon the changes of value of the North Atlantic Oscillation indicator (NAO), the concentration of the volcanic dust in the atmosphere (DVI), and the solar activity. In this context another novelty is constituted by the demon- stration of the dominating role of the volcanic eruptions in the shaping of the climate of Poland during the
