    Opis:
    On January 1, 2020 the new Foreign Investment Law of the People’s Republic of China (中华人民共和国外商投资法) entered into force to promote investments in China. The aim of the law is to foster cross border investments. This law was passed on March 15, 2019 by the National People’s Congress. The Chinese FDI legal framework is composed of a set of laws and regulations that are dynamically shaping the economic reality. What are the possible tensions between the new law and the complex system of values in China? Is the new law an agent of implementing de facto social development? In summary, the results show that there is a complex relationship between FDI and social development in China. The new Chinese law might be an inspirational source of non-European legal tradition for Central Europeans.

    Opis:
    The paper focuses on adapting the random cellular automata (RCA) method concept for the unconstrained grain growth simulation providing digital microstructure morphologies for subsequent multi-scale simulations. First, algorithms for the generation of initial RCA cells alignment are developed, and then the influence of cells density in the computational domain on grain growth is discussed. Three different approaches are proposed based on the regular, hexagonal, and random cells’ alignment in the former case. The importance of cellular automata (CA) cell neighborhood definition on grain growth model predictions is also highlighted. As a research outcome, random cellular automata model parameters that can replicate grain growth without artifacts are presented. It is identified that the acceptable microstructure morphology of the solid material is obtained when a mean number of RCA cells in the investigated neighborhood is higher than ten.

    Opis:
    The paper presents results of the research on traction properties of two tractor tyres used on two agricultural grounds. The first ground was a stubble and the second one cropland. The investigated tyres had the same structure (diagonal, with a traditional tyre tread but different external dimensions. The research was carried out in field conditions with the use of a stand aggregated with a farm tractor. Analysis covered traction efficiency, slide, towing power and power lost on the rolling resistance and wheel slide. Based on the obtained results it was concluded that on a ground with lower compaction, the values of power losses were higher and traction efficiency was lower. Moreover, it was proved that the value of the power lost for rolling resistance had a decisive impact on the values of traction efficiency.
    W pracy przedstawiono wyniki badań właściwości trakcyjnych dwóch opon ciągnikowych eksploatowanych na dwóch podłożach rolniczych. Pierwszym podłożem było ściernisko, natomiast drugim gleba uprawna. Badane opony posiadały taka samą konstrukcję (diagonalne, o klasycznej rzeźbie bieżnika), lecz odmienne wymiary zewnętrzne. Badania przeprowadzono warunkach polowych z wykorzystaniem stanowiska agregatowanego z ciągnikiem rolniczym. Analizowanymi właściwościami były sprawność trakcyjna, poślizg, moc uciągu oraz moce tracone na opór przetaczania i poślizg koła. Na podstawie uzyskanych wyników stwierdzono, że na podłożu o mniejszej zwięzłości wartości strat mocy były wyższe, a sprawność trakcyjna niższa. Ponadto wykazano, że wartość mocy traconej na opór przetaczania miała dominujący wpływ na wartości sprawności trakcyjnej.

    Opis:
    Introduction: The perforation of gloves during surgical procedures is quite common. A cheap and quite effective method of reducing the risk of blood-borne infections is wearing two pairs of gloves. Unfortunately, some surgeons are reluctant to it, and they report decreased dexterity and sensation. The aim of the study was to evaluate surgeons’ double-gloving practices to determine the factors related to compliance. Material and methods: An anonymous, 21-question survey in Polish was sent by post to 41 surgical departments. The questions concerned: demographic data, type of surgical gloves used, allergy to latex, number of surgeries performed, frequency of using double gloves and negative impressions from using them and finally, the frequency of needlestick injuries during surgical procedures. Results: We received 179 questionnaires back. More than 62% of the surgeons believe that double gloves provide better protection than a single pair, 24% do not believe in this, and 14% have no opinion. Only 0.6% of respondents always use double gloves during surgery, 19% double glove in at least 25% of cases and 68% do it occasionally. 13% of the surgeons declared that they had never worn double gloves. During high-risk procedures, 86% of respondents wear double gloves. About half of respondents (50.3%) report discomfort while wearing double gloves; 45% – decreased dexterity; about 30% complain of numbness and tingling; and 64% – decreased sensation. Conclusion: Due to the high number of surgical glove perforations and relatively high prevalence of needlestick injuries, it is necessary to use methods that reduce the risk of transmission of pathogens. The habit of using a double pair of gloves should be implemented especially among young surgeons starting to train in their specialities. Consequently, the period of initial discomfort will be combined with the acquisition of surgical skills, which will allow for gradual acclimatization.

    Opis:
    Introduction. The threshold of compulsory schooling for prematurely born children is of particular importance. It’s a period of intense physical development which may increase the risk of scoliosis. Aim. The aim of this research is to determine whether age, gender, BMI value and selected elements of perinatal interview discriminate the results of screening test aimed at detection of scoliosis and flexibility disorders in group of preterm children at the beginning of school age. Material and methods. The study population consisted of 61 preterm children aged 5-8 years. The study included perinatal interview, BMI assessment, screening tests to detect scoliosis and flexibility. Results. Statistically significant dependence was obtained between age and normal and abnormal results of the screening test aimed at detection of scoliosis and between the result of the screening test for detecting flexibility disorders and: age, number of foetuses, assessment on the Apgar scale. Conclusion. The results of screening test aimed at occurrence of scoliosis in group of preterm children are significantly correlated with the age and screening test aimed at occurrence of the flexibility disorders are discriminated by age, origin from monoor multi-foetus pregnancy and assessment on the Apgar scale
