The impact of addition of olive oil on thermal degradation of refined rapeseed oil
PublicationFats are an important component of the everyday diet and have a significant impact on the proper functioning of human organism. However, during the process of frying chemical transformations take place in the oil; hence fats characterised by high oxidative stability should be given preference. The aim of this work was to determine the quality of rapeseed oil, blended oil, and refined olive oil, all sourced from the domestic market....

Overall color parameter as a parameter determining the level of oxidation of olive oil
PublicationEdible fats are an important part of a human daily diet. They have a significant effect on the proper functioning of the human body. During frying, the oil is chemically modified and the fats consumed should have the highest oxidation stability. The subject of the study were samples of olive oil bought at local markets in Gdansk. Samples were heated at 20 °C, 60 °C, 100 °C, 140 °C and 180 °C. The aim of the study was to determine...

Thermal degradation assessment of canola and olive oil using ultra-fast gas chromatography coupled with chemometrics
PublicationOil blending is often used to enhance the properties of vegetable oils. The admixture of a more thermally stable oil makes the resulting blend more suitable for use in frying. A new method of quality assessment of vegetable oils used in frying is presented in this paper. In this method, ultra-fast gas chromatography coupled with flame ionization detector and chemometrics is employed. Principal component analysis was used for data...

Concentration of Potentially Bioactive Compounds in Italian Extra Virgin Olive Oils from Various Sources by Using LC-MS and Multivariate Data Analysis
PublicationHigh quality extra virgin olive oils represent an optimal source of nutraceuticals. The European Union (EU) is the world’s leading olive oil producer, with the Mediterranean region as the main contributor. This makes the EU the greatest exporter and consumer of olive oil in the world. However, small olive oil producers also contribute to olive oil production. Beneficial effects on human health of extra virgin olive oil are well...

Experimental research on helical coil biomass boiler with oil as a heating fluid
PublicationThis paper presents an experimental research of helical coil biomass boiler with thermal oil heating agent. Heat exchanger consists of two coaxial helical coils swept by the flue gases. The burner is a single vertical retort connected to the fuel tank (wooden pellets). The boiler is a part of micro-power plant in which the heat from the boiler is exchanged with low-boiling HFE7100 to produce steam for a custom steam turbine. The...

Evaluation of surfactant and biosurfactant mixture usefulness in oil removal from soil, based on physicochemical studies and flushing experiments
PublicationZbadano aktywność powierzchniową i właściwości zwilżające surfaktantu niejonowego - Rokanolu NL6, biosurfaktantu - JBR 425 i ich mieszanin. Na podstawie tych badań określono zdolność tych surfaktantów do usuwania oleju syntetycznego (PAO 6) z piasku. Roztwory surfaktantów zostały użyte do przemywania złoża piaskowego w kolumnie oraz odmywania piasku metodą dynamiczną. Testy kolumnowe z roztworami Rokanolu NL6 i JBR 425 dały niskie...

Non-linear FEM analysis of earthquake-induced pounding between the main building and the stairway tower of the Olive View Hospital
PublicationCelem artykułu jest dokładna, trójwymiarowa analiza MES dotycząca zderzeń pomiędzy budynkiem głównym a konstrukcją wolnostojącej klatki schodowej szpitala Olive View podczas trzęsienia ziemi San Fernando w roku 1971. Wyniki analizy pokazują, iż kolizje mogą prowadzić do znacznego wzrostu odpowiedzi lżejszej konstrukcji klatki schodowej, powodować uszkodzenia w miejscach kontaktu oraz potęgować uszkodzenia u podstawy tej budowli....

Oxygen accumulation rate with and without live bacteria in column bioreactors
PublicationBadano wnikanie i akumulację tlenu w reaktorach airlift z cyrkulacją zewnetrzną. Stosowano reaktory z odwrotną warstwą fluidalną w strefie opadania, warstwą fluidalną w strefie wznoszenia oraz reaktor z cyrkulującą zawiesiną. Badano wpływ prędkości przepływu powietrza oraz stężenia cząstek stałych na szybkośc akumulacji tlenu w cieczy w reaktorach nie zawierających bakterii oraz w obecności bakterii Acinetobacter calcoaceticus...

Analysis of volatile oxidation products in rapeseed oil
PublicationCelem pracy było opracowanie metody umożliwiającej określenie stabilności oksydatywnej oleju rzepakowego na podstawie analizy lotnych produktów utleniania lipidów. Na etapie opracowywania metody dobrano optymalne parametry ekstrakcji lotnych analitów techniką SPME. Przeprowadzono również elementy walidacji tej procedury. Zaproponowano też substancje markerowe mogące posłużyć za wyróżniki procesu utleniania lipidów.

Analysis of causes of crude oil tankers' disasters
PublicationW referacie przedstawiono dane statystyczne dotyczące rozlewów ropy surowej oraz opis katastrof tankowców w latach 1999-2003. Zlekceważenie problemów poprawnej eksploatacji wielokrotnie kończy się tragicznie. Z tych powodów wypełniony ropą grecki tankowiec ''Amaragos'' czy też maltańska ''Erika'' złamały się na pół i poszły na dno. Przykładów takich jest więcej. W referacie przedstawiono analizę przyczyn rozlewów olejowych według...

The influence oil additives on spread cracks in silicon nitride
PublicationThe paper presents an experimental study of the influence of oil additives (Cl, S, P, cerium dioxide (CeO2)) on spread cracks in silicon nitride. The additives Cl, S, P are bound in molecules in liquid form soluble in the base oil. The CeO2 is purely in powder form in suspension. The use of CeO2 powder was made based on the good results of polishing of silicon nitride. A ceramic angular contact ball bearing was modelled using a...
