International trade is a field to which graphs and their analysis can be successfully applied. International trade can be defined as the flow of goods between the economies of different countries in the world. The term itself includes the following issues: the flow of capital, labour force migration, the exchange of goods and services, and the transfer of scientific and technical thought. This paper focuses only on foreign trade defined as the exchange of goods and services between a particular country and its surroundings. The analysis has been kept to the countries of European Union. The first part of the article characterises the concept of foreign trade and how it is measured. The next part introduces a model of international trade in the European Union based on graphs, with nodes representing the countries and the edges – the flows between them. The last part of the work consists of an analysis of the model and final conclusions.

Martin Heidegger hielt bei der Übernahme des Rektorats in Freiburg am 27.05.1933 die Antrittsrede „Die Selbstbehauptung der deutschen Universität“. In dieser Rede hat er programmatische Vorstellungen zur Erneuerung der Universität zum Ausdruck gebracht, mit der Berücksichtigung eines aktiven Engagements der Studenten, von denen er einen „Dienst“ auf drei Ebenen erwartete — als „Wehr-“, „Arbeits-“ und Wissenschaftsdienst. Die Rede entsprach zwar nicht den Hauptvoraussetzungen des NS-Bildungsprogramms, zeugt aber von seinem Beitrag zur nationalsozialistischen Gestaltungspolitik der deutschen Universität.

Martin Heidegger solemnly assumed the rectorate of the University of Freiburg on 27 May 1933, delivering the famous inaugural address Die Selbstbehauptung der deutschen Universität. In the speech, he presented his programme for the revival of the University, which included the active involvement of students from whom he expected a threefold type of service – Wehrdienst, armed service, Arbeitsdienst, labour service, and Wissenschaftsdienst, knowledge service. Even though such concepts were not congruent with the main objectives of the NS-Bildungsprogramm, it reflected his involvement in the National Socialist policy of shaping the German University.

Martin Heidegger, obejmując urząd rektora Uniwersytetu we Fryburgu 27 maja 1933 r., wygłosił mowę inauguracyjną Die Selbstbehauptung der deutschen Universtität. Zaprezentował w niej programowe założenia odnowy Uniwersytetu z uwzględnieniem czynnego zaangażowania studentów, od których oczekiwał „służby” w potrójnym znaczeniu — jako „Wehr-”, „Arbeits-” i „Wissenschaftsdienst”. Wprawdzie nie odpowiadała ona głównym założeniom NS-Bildungsprogramm, jest ona jednak świadectwem jego zaangażowania w narodowosocjalistyczną politykę kształtowania niemieckiego uniwersytetu.

Triterpene saponins (saponosides) are found in a variety of higher plants and display a wide range of pharmacological activities, including expectorant, anti-inflamatory, vasoprotective, gastroprotective and antimicrobial properties. Recently, a potential anticancer activity of saponins has been suggested by their cytotoxic, cytostatic, pro-apoptotic and anti-invasive effects. At high concentrations (more than 100 µM) saponins exert cytotoxic and haemolytic effects via permeabilization of the cell membranes. Noteworthy, the inhibition of cancer cell proliferation, the induction of apoptosis and attenuation of cell invasiveness is observed in the presence of low saponin concentrations. Saponins might affect the expression of genes associated with malignancy. These alterations are directly related to the invasive phenotype of cancer cells and depend on "cellular context". It illustrates the relationships between the action of saponins, and the momentary genomic/proteomic status of cancer cells. Here, we discuss the hallmarks of anti-cancer activity of saponins with the particular emphasis on anti-invasive effect of diverse groups of saponins that have been investigated in relation to tumor therapy.
