Laser diffraction was used for determination of particle size of various emulsions. Mean particle size, fractions' number, and dispersion coefficients of tested systems are presented. Stability of greasing emulsions in relation to their pH was also tested. It was found out that determination of droplet size distribution in fat emulsions allows prediction of their properties (stability). The parameter may be helpful in selection of appropriate production process parameters, composition, and control of marketed emulsion systems during their storage. The purpose of the study was to determine applicability of a laser diffraction method for evaluation of stability of selected dispersion systems in food and chemical industry. © 2013 Copyright Taylor and Francis Group, LLC.

In the field of road safety, the concept of 'risk' is used to define a measurable level of road safety dependent on numerical accident exposure value. This is an approach different (even contradictory) to calculate the level of security, measured by the number of accidents or injuries. So, whether otherwise - risk assessment is needed to improve the safety of road transport and define priorities in the field of public health. The article presents the concept of risk and selected problems of risk analysis in road traffic.

At a time of huge economic challenges, innovativeness is perceived as a way of overcoming difficulties, fostering and assuring socio-economic growth of particular countries. It is necessary to improve competitive standing of enterprises both in domestic and international economies. Launching of new or improved products, application of state of the art technologies and of new organisational and management solutions are key to enhanced effectiveness and better competitiveness of enterprises. Innovation standards of Polish enterprises are considerably lower than those of businesses operating in countries of the old European Union, therefore so much attention is paid to these issues. This paper undertakes to analyse innovative activities of enterprises in the Polish economy. Based on the report 'Innovation Union Scoreboard', a comparative analysis of Poland's innovation standards in relation to other member states of the European Union is conducted, levels and structure of financial spending on innovative activities incurred by Polish industrial enterprises are discussed using statistics published by the National Office for Statistics and Ministry of Economy.

Head checking defects pose a major threat to the safety of railway traffic. Because of their location and small dimensions they cannot be detected with the use of traditional ultrasonic methods. An alternative method is an optical method using a laser diode as the transmitter and a PIN diode as the receiver. Head checking defects cause the dispersion of laser rays what in turn causes the generation of undetermined signal containing the information about defects. Because of this the authors dealt with algorithms used to extract and classify these defects. Wavelet transforms and fuzzy sets have been proposed. The efficiency of these methods has been compared. © 2010 Springer-Verlag.
