Under the name of ‘pivot derivation’, this article reconsiders a phenomenon known by Arab grammarians and lexicographers as well as by Arabists and Semitists: the derivation of a secondary lexical family from a primary one, via a morphologically ambiguous form. Through the examples of ma‘īn, masīḥ and ma/isāḥa, and a rereading of Mez (1906), it proposes several extensions of this type of derivation, made possible not only by homophony but also by homography or phonetic accidents, and compatible with the borrowing from other languages.

The author of the article makes an attempt to show borrowings from the perspective of their penetration into Polish and presents the most common and less frequent words. Special attention is paid to the usage and context of separate words in pairs (native word ~ borrowed word) in two idiolects that demonstrate the preservation of the Polish language tradition and show a new wave of loanwords as well. The author describes some word-formative peculiarities of verbs in the dialectal Polish language of Gródek Podolski. This text can be a supplement to the previous papers concerning borrowed vocabulary and morphological derivation in Polish dialects.

How is formed the adjective fettleibig (obese)? It may seem an evident derivate from fett (fat) and Leib

(body); however, the NP fetter Leib is as seldom as the adjective is frequent: this sounds paradoxical.

In this contribution, a new way of explaining the formation of this adjective is explored: fettleibig

appears as a subsistance of a in past times rich -leibig-paradigm. Therefore, in a synchronic view, this

adjective is not explained as a derivate, although it remains mainly transparent.

Water names, using the genetic-motivational criteria, can be divided into two superior groups: deappellative and deproprial hydronyms. Among the hydronyms derived from proper names, one can distinguish between the detoponymic and deanthroponymic. The names of flowing waters from anthroponyms are the subject of this article. Preliminary statistical data regarding deanthroponymic potamonyms in the Vistula river basin, their chronology, naming models, word formation bases and geographical distribution are presented. The results of the analysis show that the deanthroponymic potamonyms account for approximately 6.8% of the names of flowing waters of the Vistula river basin, estimated at more than 13,500. They appear sporadically in documents as early as in the 13th century, with only 12% visible until the 16th century, with most of them not being noticed until the 19th and 20th centuries. Such a statistical distribution is typical for the names of the flowing waters of that basin. Deanthroponymic names of rivers represent a variety of naming models, but most often appear as a part of compound names created with the suffix -ów, one-word formations with the same suffix and derivatives from the suf. -ka. They mainly identify objects located between the Soła River and the Dunajec River, especially in the Dunajec River basin, so in mountainous and submontainous areas, as K. Rymut claimed. The basis of such potamonyms are mainly personal names with different motivations, rarely being ethnonyms and first names.

There is general agreement that primary pyrolysis products of end-of-life tyres should be valorised to improve the economics of pyrolysis. In this work, tyre pyrolysis char (TPC) is produced in a pyrolysis pilot plant designed and built at our home university. The produced TPC was upgraded to tyre-derived activated carbon (TDAC) by activation with CO2, and then characterised using stereological analysis (SA) and nitrogen adsorption at 77 K. SA showed that the grains of TPC and TDAC were quasi- spherical and slightly elongated with a 25% increase in the mean particle cross-section surface area for TDAC. The textural properties of TDAC demonstrated the BET and micropore surface areas of 259 and 70 m2/g, respectively. Micropore volume and micropore surface area were 5.8 and 6.7 times higher for TDAC than TPC at  2 nm, respectively. The n-hexane adsorption was investigated using experiments and modelling. Eight adsorption isotherms along with three error functions were tested to model the adsorption equilibrium. The optimum sets of isotherm parameters were chosen by comparing sum of the normalized errors. The analysis indicated that the Freundlich isotherm gave the best agreement with the equilibrium experiments. In relation to different activated carbons, the adsorption capacity of TDAC for n-hexane is about 16.2 times higher than that of the worst reference material and 4.3 times lower than that of the best reference material. In addition, stereological analysis showed that activation with CO2 did not change the grain’s shape factors. However, a 25% increase in the mean particle cross-section surface area for TDAC was observed.

The paper presents the effect of tin on the crystallization process, microstructure and hardness of cast iron with compacted (vermicular) graphite. The compacted graphite was obtained with the use of magnesium treatment process (Inmold technology). The lack of significant effect of tin on the temperature of the eutectic transformation has been demonstrated. On the other hand, a significant decrease in the eutectoid transformation temperature with increasing tin concentration has been shown. It was demonstrated that tin narrows the temperature range of the austenite transformation. The effect of tin on the microstructure of cast iron with compacted graphite considering casting wall thickness has been investigated and described. The carbide-forming effect of tin in thin-walled (3 mm) castings has been demonstrated. The nomograms describing the microstructure of compacted graphite iron versus tin concentration have been developed. The effect of tin on the hardness of cast iron was given.

Since plant responses to selenium nanoparticles (nSe) had not been clarified, this study was carried out to evaluate the effects of nSe (10 and 100 μM) on photosynthesis performance, ion homeostasis, antioxidant system, and phenylpropanoids in strawberry exposed to salt stress. Inductively Coupled Plasma-Mass Spectroscopy analyses indicated that foliar-applied nSe can be taken up by leaves and trans-located to roots. Salinity led to an increase in Na concentration and reductions in Ca and K contents which were relieved by the nSe applications. Moreover, the nSe treatment at 10 μM alleviated the NaCl-induced lesion to PSII functioning, contributing to improvement in water-splitting complex (Fv/Fo) under salinity. The exposure to nSe at a concentration of 100 µM exhibited a moderate stress, determined by the increases in hydrogen peroxide (H2O2) and lipid peroxidation rate (membrane integrity index). The nSe10 treatment increased catalase activity and phenylpropanoid derivatives contents (salicylic acid, catechin, and caffeic acid) and decreased the content of oxidants under salinity condition. Consequently, nSe utilization at a suitable dose can be an effective method to alleviate signs of salt stress via improvements in photosynthesis, ion hemostasis, photosynthesis performance, salicylic acid (a vital signaling defensive hormone), and antioxidant machinery.

The author presents basic lines of semantic derivation from Proto-Slavic root *ži-/*živ- in Polish. Working on her theme she discovers an interesting old Slavic isogloss: while in West-Slavic languages the names for concepts ‘life/live’ and ‘animal’ have different etymology, in South- and East-Slavic, with the exception of the Ukrainian language – they have common origin.
