Bezpieczeństwo osób ze środowiska LGBT

Grzegorczyk Weronika

Security Review

2019

nr 1(10)

20--33

The article raise issues of discrimination, problem of inheriting prejudices, subjective perception of safety and opinion of non-heterosexual on ways to combat homophobic attitudes in society. An attempt was made to find out the causes of homophobia and to present research that aim was to find ways to effectively improve the situation of LGBT and improve their sense of safety and trust in justice. The analysis refers to the opinion about the scale of the phenomenon of discrimination and methods of combating it.

Experimental study of Fe-Ni-Ti-Cr system

Hoppe Viktoria, Gibas Anna, Grzegorczyk Weronika, Małecki Marcin, Hasiak Mariusz

Interdisciplinary Journal of Engineering Sciences

2019

Vol. 7, no. 1

1--14

The research comprises a discussion about a formation of intermetallic phase with stoichiometric composition Fe2Ti, called Laves phase, and influence of chromium on the whole structure containing this phase by means of comparison of the two alloys. A base Fe35Ni35Ti30 alloy was used as a reference and then compared with a Fe-Ni-Ti chromium doped - Fe30Ni35Ti30Cr5 alloy. The study of microstructure performed with scanning electron microscope enabled to distinguish different phases. These regions are rich in mixture of Fe-Ni and Ti-Ni elements. The identified phases are Fe2Ti and Ni3Ti which was confirmed by X-ray diffraction and simultaneously it is consistent with energy dispersive spectroscopy results. Differential scanning calorimetry confirmed also multi-phase composition. As a result different hardness was measured for these phases using nanoindentation. The overall hardness was established using the Vickers method.
