Key-Marker Volatile Compounds in Aromatic Rice (Oryza sativa) Grains: An HS-SPME Extraction Method Combined with GC×GC-TOFMS
PublicationThe aroma of rice essentially contributes to the quality of rice grains. For some varieties, their aroma properties really drive consumer preferences. In this paper, using a dynamic headspace solid-phase microextraction (HS-SPME) system coupled to a two-dimensional gas chromatography (GC×GC) using a time-of-flight mass spectrometric detector (TOFMS) and multivariate analysis, the volatile compounds of aromatic and non-aromatic...

High-performance liquid chromatography of di- and trisubstituted aromatic positional isomers on 1,3-alternate 25,27-dipropoxy-26,28-bis-[3-propyloxy]-calix[4]arene-bonded silica gel stationary phase.
PublicationOtrzymano nową fazę stacjonarną na bazie dipropyloksy pochodnej kaliks[4]arenu w konformacji 1,3-naprzemianległej chemicznie związaną z żelem krzemionkowym. Przeprowadzono badanie selektywności i sprawności tej fazy w rozdzielaniu izomerów konstytucyjnych benzenu. Zaprezentowano wyniki badania wpływu warunków chromatograficznych (pH fazy ruchomej, temperatura, stężenie modyfikatora organicznego) na zdolność rodzielczą tej nowej...

Collective action against same-sex marriages_online research in Poland
Open Research DataThe study was conducted in the context of people opposing the equality of sexual minorities. At the beginning of the survey, each respondent was asked to mark their support for the equality of rights of heterosexual and homosexual persons, on a scale from -3 (definitely not) to 3 (definitely yes). The subsequent questions of the survey were formulated...

The influence of microstructure on the corrosion resistance for some titanium-based alloys
Open Research DataThis dataset contains scanning electron microscopy (SEM) micrographs revealing the microstructure of some Ti-based alloys, namely: Ti-6Al-4V (file name: TiV), Ti-6Al-7Nb (file name: TiNb) and TC21 (file name: TiAlSnZrMoCrNbSi) alloys and their localized corrosion as a result of passive layer breakdown in a corrosive environment, ie. 0.9% NaCl solution...

Effect of Laser Treatment on Intrinsic Mechanical Stresses in Titanium and Some of Its Alloys
PublicationLaser surface treatment conducted at different power levels is an option to modify titanium bone implants to produce nano- and microtopography. However, such processing can lead to excess mechanical stress within the surface layer. This research aims to calculate the level of such residual stresses after the surface processing of Ti grade IV, Ti15Mo, and Ti6Al7Nb alloys with an Nd:YAG laser. Light and scanning electron microscopies...

Some fundamental aspects of self-levitating sliding contact bearings and their practical implementations
PublicationIn this study, fundamental aspects and mechanisms of acoustic levitation together with governing equations are presented first. Then, the acoustic levitation phenomenon is considered as a new way to design air suspension systems capable of self-levitation. A particular emphasis is laid on journal bearings and their specific geometrical configuration. A practical feasibility of using acoustic levitation to separate contacting surfaces...

Modelling of some stealth features for a small navy ship at the concept design stage.
PublicationIn this paper the basic research problems associated with modelling the basic stealth features for a small navy ship at the concept design stage are introduced. Amongst the major stealth features considered are: the modification of the immersed ship hull form by a rapid change of the ship loading condition, and modification of the ship boundary layer by the hull skin cover. The other stealth features of the ship are not presented...

Hysteresis curves and loops for harmonic and impulse perturbations in some non-equilibrium gases
PublicationEvolution of sound in a relaxing gas whose properties vary in the course of wave propagation, is studied. A relaxing medium may reveal normal acoustic properties or be acoustically active. In the first case, losses in acoustic energy lead to an increase in internal energy of a gas similarly as it happens in Newtonian fluids. In the second case, acoustic energy increases in the course of sound propagation, and the internal energy...
