The aim of this pictorial essay is to present the mould based HDR brachytherapy technique used at the HolycrossCancer Center for penile cancer patients. We use images to describe this method step by step.

The aspects relating to unmanned aircraft and their target acquisition systems are continuously being developed. The subject of the study is a target acquisition system with a thermal camera. A control system is presented consisting of three subsystems. Open- and closed-loop control systems are used. Experimental results unambiguously show that this is a promising line of research and form the basis for further efforts on the topic.

Stress calculations are necessary to determine the feasibility and profitability of a heat storage tank’s construction. The article presented normative methods of stress calculations for a heat storage tank. Results were verified by finite element analysis. These stress calculations enabled us to determine wall and weld thickness. The calculations were made on the example of a tank with a nominal pressure of 10 bar. The work undertook an extensive analysis of the stresses occurring in a pressure tank, described the finite element method and showed examples of ways in which it could be used. During stress analysis, three types of materials were compared: carbon steel St0 (S185), stainless steel (304) and boiler steel (P 265 GH). A brief overview of types of thermal energy storages was also provided.

In Poland winter wheat is grown on the area of 1.600.000 ha. Most of the plant protection treatments are being done without thorough analysis of real threats from pests and diseases. The aim of the research is to develop the optimal program of wheat protection against pests and diseases based on integration of various methods of plant protection. Two programs: conventional and integrated were compared. In integrated program the eventual needs and terms of treatments were estimated on the basis of detailed observations of plant infection, pest appearance, their natural enemies and thorough analysis of weather conditions and forecasts. The role of disease resistant wheat varietes and nitrogen fertilizers was also analysed. The research took into account beneficial entomofauna and its influence on pest numbers as well as influence of chemicals used in agriculture on their species. As the result the selective pesticides, safe to beneficial organisms, were selected. The quantity and quality of winter wheat yield was analysed, including protein and gluten contents. The economic effectiveness of various programs of wheat protection against pests and diseases was assessed. The results of research are important both in practical and scientific sense.
