This paper presents the results on the effects of die-casting process on the strength parameters of castings of the aluminium AlSi9Cu3 alloy

belonging to the group of EN AB-46000, made on renovated high pressure die-casting machine. Specimens for quality testing were taken

from the places of the casting most loaded during the service. The aim of a research was to prove how the new die-casting process control

capabilities influence on the tensile strength of the cast material defined as a value of the breaking force of the specimens. It has been

found that it is possible to specify a set of recommended settings valves of second (II) and third (III) phase, which are responsible for

filling the metal mould on die-casting pressure machine. From the point of view of the finished cast element, it was noticed that exceeding

the prescribed values of valve settings does not bring further benefits and even causes unnecessary overload and reduce the durability of

the mold. Moreover, it was noticed that reduction of the predetermined setting of the second phase (II) valve leads to the formation of

casting defects again.

The purpose of this paper is an attempt to reflect on the beginnings of Ukrainian modernism. The article is an analysis of the “Open letter to Ukrainian writers” by Mykola Voronyi and his polemics with a well-known Ukrainian writer, Ivan Franko. This letter, which was published in the journal “Literaturno-Naukowy Wisnyk” in 1901, is a very important document of the epoch, bearing the mark of a literary manifesto. This little note made the Ukrainian intelligentsia aware of the crisis of so-called narodnytstvo poetics and the need for far-reaching modernization of Ukrainian literature. The writer postulated the rejection of adopted schemes in favour of the latest European trends in literature. The attempt to implement the program demands was an edition of Mykola Voronyi’s literary collection, “From the Valleys and Above the Clouds”, which has also been analyzed and discussed in this paper. The author concludes that the “Open letter to Ukrainian writers” can be considered one of the first manifestations of Ukrainian modernism
