The custom of burying the dead is not merely commonly accepted by the Christianity way of disposal of the human body after death. It is most deeply rooted and perfectly expressing Christian anthropology, revealed in the Holy Scriptures as a consequence of original sin, a sign of hope in the resurrection, and imitation of Christ, who was buried in the tomb. In the Catholic view, the burial is a corporal work of mercy, an act of care for the dead and their loved ones. Gaining popularity the practice of cremation is accepted by the Church for the sake of hygiene, economy, or community. Human remains, also in the form of ashes, always must be buried or placed in the columbarium. The Church does not allow human body disposal by resomation or promession. Alternative forms of memorializing the deceased, though attractive esthetically and sentimentally, are not only outlandish in Christian culture, but also contrary to the Christian teaching on origins, nature, and destination of the human person.

This article deals with the name of the town Węgrów on the river Liwiec, whose name is based on the obscure hydronym Węgra Potok. This name is juxtaposed with another place name, Węgra, which is found near Przasnysz and is named after the river Węgra (today known as Węgierka), as well as other names beginning with wągr-||węgr-. The author challenges Witczak’s (2015) hypothesis that the name of Węgra comes from the Sudovian (Jatvingian, Yotvingian) language. The article raises historical, archaeological and geographical arguments that oppose the possibility of a Yotvingian influence in these regions. Consequently, the author contends that the place names have a Slavonic root, linked to the noun węgorz (a type of fish), or the meandering nature of both rivers. There is also a discussion of the name patok||potok (stream/brook).

The paper presents the basic input data and modelling results of IGCC system with membrane CO2 capture installation and without capture. The models were built using commercial software (Aspen and GateCycle) and with the use of authors’ own computational codes. The main parameters of the systems were calculated, such as gross and net power, auxiliary power of individual installations and efficiencies. The models were used for the economic and ecological analysis of the systems. The Break Even Point method of analysis was used. The calculations took into account the EU emissions trading scheme. Sensitivity analysis on the influence of selected quantities on break-even price of electricity was performed
