Opis:: The surface of NiTi shape memory was modified by deposition of chitosan-ZnO thin film. The electrodeposition process was carried out at room temperature at voltage-time conditions: 10 V/30 s, 10 V/300 s, 20 V/30 s, or 20 V/300 s. Structure of the obtained coatings was studied by means of grazing incidence beam X-ray diffraction. Distribution of the zinc oxide particles in the chitosan matrix was observed with use of scanning electron microscopy. It was found that depending on the electrodeposition parameters, the structure of the obtained chitosan-ZnO coatings varies from amorphous to coarse-grained.

Opis:: The paper analyses potential applications of modern car transport on farms with area over 20 ha agricultural land (AL). A vast majority of farms are capable of using transport by means of truck with load capacity between 8 and 10 tons. The greatest difficulty is a possibility of performing a safe 360°turn. In this respect only 45.90% of farms have this option, however their percentage is growing with increasing farm area. On the other hand, in case of on average 21.31% of the analyzed farms the entrance may be hindered at some times due to the access from a field track. The width of the entrance gate and the culvert bridge bearing capacity (in 8.20% it was too low) have only slight influence on the discussed issues.
