Trueness and precision of a method for determining the water content (%) of food and chemical products based on infrared radiation with a wavelength in the range (2.70÷7.21 μm) was evaluated. The most accurate measurements for food products were obtained when the heat source was a radiant heater with a radiation wavelength of 7.21 μm, a trueness deviation of 0.01%. When heated with radiation with wavelengths (from 3.32 μm to 7.21 μm), the trueness of the measurement ranged (0.03% ÷0.13%) for chemical products. The shortest analysis time for food products was found when the analysis was carried out using an IR source with a wavelength of 7.21 μm, while for chemical products, a heat source with a wavelength of 2.70÷7.21 μm was optimal. According to the results of the analysis, the use of IR radiation with a wavelength range of 3.32÷7.21 μm is an alternative for accurate measurements.

W artykule konfrontuję koncepcję osoby Petera Strawsona z koncepcją osoby Paula Ricoeura, traktując je jako reprezentatywne ilustracje podejścia semantyczno-ontologicznego i pragmatyczno-egzystencjalnego (lub hermeneutycznego) zarazem do problemu języka i do problemu bytu zwanego osobą. Zaznaczam różnice między tymi podejściami, ale wskazuję także na ich punkty wspólne. Zgodnie z przedstawioną interpretacją, Ricoeur w swojej próbie przezwyciężenia ograniczeń semantycznej teorii osoby rozwija i uwypukla wątki, które w sposób marginalny były obecne już w teorii Strawsona, a skądinąd docenia znaczenie tych, które w tej teorii były pierwszoplanowe, chociaż je relatywizuje. Stosunek Ricoeura do Strawsona pokazuje złożoną relację między tzw. filozofią kontynentalną i tzw. filozofią analityczną.

Scientific output analysis in Poland takes place in many ways: by use both central and local databases. The article discusses the contents and bibliometric functions of the most important bibliographic databases, i.e. “People of science”, Polish Scientific Bibliography and employeers local registration system Expertus. The authors evaluate these tools from the perspective of the ability to make comparisons of the effectivity of individual researchers as well as to stimulate the development of scientific careers. As alternative solution relative to the analytical spectrum of all external tools, the authors present own application that allows visualization of scientific achievements. According authors’ observation, the Scientific Visualiser can enrich the individual information space of the contemporary scientist. Dedicated application certainly facilitates the evaluation of the publication activity, increases an awareness of updating of the bibliographic data, helps in discovering the relationship between the research fields, inspires to broaden intelectual horizons and cooperation networks. From another side, it can also be a tool supporting administration activities, such as: employees evaluation, promotion proceedings, accreditation, experts selection, distribution of funds.
