    Opis:
    This paper presents the results of the study on morphological differentiation of seeds of five Polish species of the genus Sorbus L. (S. aria (L.) Crantz, S. aucuparia L. Emend. Hedl., S. chamaemespilus (L.) Crantz, S. intermedia (Ehrh.) Pers. and S. torminalis (L.) Crantz). The biometric data of 1980 seeds were subjected to multivariate statistical analysis in attempt to define intraspecific variation and to find differences between studied taxa. Most of the seed traits are significantly correlated and are characterised by moderate level of variation. Seeds of S. aucuparia (both subspecies) are the least variable while seeds of S. torminalis and S. intermedia the most. On the basis of size and shape traits of Sorbus seeds only seeds of S. aucuparia can be definitely distinguished from the others.

    Opis:
    In this work, we performed comparative studies of the effect of surface preparation of Ti6Al4V and Ti6Al7Nb biomedical alloys and the influence of endothelial cells on their corrosion behaviour in PBS (Phosphate Buffered Saline). Two different methods of surface modification were applied – polishing and sandblasting. The polished Ti6Al7Nb alloy was found to have the best resistance against general corrosion in PBS. It was characterized by the lowest corrosion rate, the widest passive range and the lowest reactivity. Both alloys prepared by sandblasting exhibited worse corrosion properties in comparison to the polished ones. This can be associated with a greater development of their surface and the presence of Al2O3 grains which caused an increase of corrosion potential but might also influence the weakening of the passive layer. Results of potentiodynamic anodic polarization indicated that more resistant to pitting corrosion was Ti6Al7Nb alloy regardless of the method of surface preparation. In those cases, anodic polarization caused only an increase of passive layer, while in the case of sandblasted Ti6Al4V alloy it caused a pitting corrosion. The results obtained allowed us to conclude that the niobium-titanium alloys had higher corrosion resistance than titanium alloys with vanadium. Moreover, it was stated that endothelial cells improved the corrosion resistance of all the titanium alloys examined.

    Opis:
    The article reports sol-gel synthesis of nanosized spinel-type lithium manganese oxide LiMn2O4 (LMO) carried out in the presence of graphene oxide (GO) and its electrochemical lithium insertion ability. The synthesis was performed in an aqueous environment with lithium acetate and manganese acetate used as precursors and citric acid as a chelating agent. The material was characterized by X-ray diffraction, SEM microscopy, Raman spectroscopy and cyclic voltammetry. The calcination step totally eliminated graphene from the final product, nevertheless its presence during the synthesis was found to affect the resulting LiMn2O4 morphology by markedly reducing the size of grains. Moreover, potentials of electrochemical lithium insertion/deinsertion reactions have been shifted, as observed in the cyclic voltammetry measurements. Along with the diminished grain size the voltammetric curves of the graphene oxide-modified material exhibit higher oxidation and lower reduction peak currents. The study demonstrates that GO mediation/assistance during the sol-gel synthesis fosters more nanostructured powder and changes the electrochemical characteristics of the product.

    Opis:
    In the automotive industry in the world continuously being sought universal driving cycle. The test should closely match the fuel consumption and emissions of toxins in the fumes of the test vehicle in its real operating conditions [4]. However, in the previously developed solid driving tests established velocity profiles differ significantly from actual driving conditions. The difference in fuel consumption, comparing the natural operation of the NEDC test reaches an average of 18%. The new version of the driving cycle should be more realistic to the everyday use of additional equipment and gadgets that are installed in modern vehicles [1]. The impact on fuel consumption by vehicles may be conditioned not only by its size and weight, but also by the geometry of the track motion, forces causing the motion and the forces acting on the car when driving on curved tracks. The vehicle encounters and overcomes all the forces that act on it while driving-resistance movement. In the energy intake through the vehicle runs in the motor changes at the expense of the energy of fuel consumed. The driving force performs work on a given stretch of road balancing (predominant) friction. On the basis of the calculated resistance movement and the energy consumption of the movement in the selected object was a comparison of the actual consumption of fuel in the vehicle with the ignition spark. Analysis was performed and found differences in three cycles: urban, extra-urban and combined.

    Opis:
    Effects of different pre-planting soil preparations and post-harvest wood debris applications in a clear-cut Scots pine plantation, on the abundance, diversity, and activity of culturable microorganisms were investigated. The investigation was done 9 years after the re-plantings had been done. This formed part of an investigation of silvicultural practices for conservation and the biological control of Armillaria and Heterobasidion in northern temperate forests (Poland). The treatments being compared, were expected to have altered the soil’s physical and chemical properties, and consequently, its biological properties. Only soft-rot microfungi from the Ascomycota and Zygomycota were detected in the soil. Fungi, including those antagonistic to Armillaria and Heterobasidion, were more abundant after shallow ploughing than after deep ploughing or ridging, and where chipped rather than coarse wood debris was left on the soil surface or incorporated. Scots pine trees had the most biomass and the least mortality after ridging and leaving coarse wood debris on the surface (associated with only a relatively moderate abundance of fungi).

    Opis:
    The Position Statement on the principles of nutrition for children aged 1-3 years emphasizes that proper nutrition of children at this age determines their optimal psychometric development and has beneficial effects on the process nutritional programming, which reduces the risk of diet-related diseases in adulthood. Continued breastfeeding in the post-infancy period, together with the proper introduction of complementary foods, supplies all the nutritional needs of the child. A varied selection of food products is important to balance out the diet of a child in the context of energy and nutrient needs. Attention should be paid to products not recommended for frequent consumption, due to the possibility of the early development of improper eating habits that can lead to undesirable health consequences. Due to the potential risk of deficiency, adequate intake of iron, iodine, calcium and vitamin D, as well as of n-3 PUFAs (which is often insufficient) should be provided. Adequate dietary energy and protein intake protects children against protein–energy undernutrition and is crucial for their proper growth and development. An important element in the assessment of the development of children involves monitoring their nutritional status and physical development by systematically measuring their body weight and length/height and analyzing their weight gain. It is necessary to diagnose the causes of being underweight/ overweight in children. Physical activity (such as outdoor walks, plays, and games) and healthy sleep hygiene are recommended. Physical activity, an adequate number of hours of sleep, and the quality of sleep in early childhood may improve immunity, reduce the risk of excessive weight gain, and consequently reduce the risk of obesity later in life. Other issues discussed include the functioning of the digestive system as one of the determinants of the nutrition of young children, basics of proper nutrition, risk of nutrient deficiencies and development of proper eating habits in early childhood.
