Opis:
The presented prognosis indicates possible directions and conditions of changes that will take place in the Polish countryside within the next few years. It should be underlined that this period will encompass both positive and negative processes. During this period 2.5 billion Euros (not including money for the Common Agricultural Policy) will be devoted to the development of rural areas. Together with domestic funds, it makes a total sum of 3 billion Euros of available financial resources. Having topped these funds up with investors’ own contributions, it will be possible to deal with total financial support of 4.5 - 4.9 billion Euros per annum. This will allow us to change the image of rural areas considerably, especially the level of technical infrastructure and the quality of productive potential of agriculture, as well as agribusiness. Therefore, the countryside and farms will have many more investment opportunities at their disposal. It is predicted that these funds should first of all be devoted to creating new work opportunities in rural areas and subsequently to improve competitiveness of farms due to their progressive concentration and technical modernisation. These processes are strongly related to each other and, therefore, one should not suppose considerable regional farm concentration without providing workplaces for farmers, especially the least skilled. On the other hand, one should mention processes that will make carrying out the intentions difficult. One of them is undoubtedly further limitation of agricultural expenses, especially after year 2013 (Common Agricultural Policy included). The reform of Common Agricultural Policy that took place in 2003 assumed stabilisation of expenses on agriculture as well as their gradual reinvesting in I and II Common Agricultural Policy levels. Further changes that might take place in the subsequent period of planning (2014-2020) are not yet known, which significantly limits the possibilities of outlining aims and priorities for Poland. It should be assumed that further limitations of funds for agriculture and rural areas in general are yet to come. The above mentioned is supported by the following three reasons: - More and more popular criticism of the Common Agricultural Policy as it is shaped right now, - Funds for Common Agricultural Policy after new members with big agricultural population (Bulgaria, Romania, Croatia, Turkey) would need to be increased, - Negotiations related to liberalisation of world markets within WTO.

Opis:
The paper is concerned with testing Cu-Mo coatings deposited over carbon steel C45 which were then eroded with a laser beam. The properties were assessed by analyzing the effects of laser eroded, texturing methodology and wear tests. The tests were conducted for Mo and Cu coatings (the anode) which were electro-spark deposited over the C45 steel substrate (the cathode) and melted with a laser beam. The coatings were deposited by means of an ELFA-541. The laser processing was performed with an Nd:YAG laser. The coatings after laser processing are still distinguished by very good performance properties which make them suitable for use in sliding friction pairs.

Opis:
Introduction. Nicotine is an alkaloid that affects the functioning of the central nervous system and produces dependence. In low doses, it acts as a stimulant and relaxant. Nicotine was reported to have pro-cognitive effects in humans and animals. However, high doses of nicotine are harmful for many organs.The aim of the study was to check whether a 30-day exposure to transdermal nicotine affects memory and biochemical parameters in mice. Materials and method. A total of 32 mice (16 males and 16 females) were used in the experiment. Mice were divided into 4 groups of 8 animals each: I control-females receiving placebo patches for 30 days, II females receiving nicotine patches for 30 days, III control-males receiving placebo patches, IV males receiving nicotine patches. Spontaneous alternation and locomotor activity were examined weekly in a Y-maze. Body mass was recorded daily. On day 30, venous blood samples were obtained and the animals were anaesthetized with CO2. Their blood was used to measure alanine transaminase (ALT), asparagine transaminase (AST), cholesterol, creatinine and glycosylated haemoglobin (HbA1C). Results. Nicotine significantly improved memory in male mice on day 8. It increased ALT and AST activities in males and females, as well as the concentration of cholesterol in their blood sera. Conclusions. In conclusion, transdermal nicotine may produce transient improvement in fresh spatial memory in male mice, but it is not a long-term effect and therefore nicotine does not seem to be appropriate for use in the treatment of neurodegenerative disorders. It elevates blood cholesterol level and thus may increase the risk of atherosclerosis and cardiovascular events; moreover, it negatively affects liver enzymes. Nicotine use is therefore not recommended.
