Imaging of graphene surface by means of tapping mode AFM
Open Research DataGraphene [1] is a material consisting of carbon planes with a hexagonal structure. One of the facts of interest from a purely scientific point of view is the very high mobility of electrons in the described material, allowing the study of relativistic effects inside a solid sample. Other features, such as bactericidal activity, make graphene an interesting...

237Np Mössbauer effect study on NpFeAsO
PublicationWe report 237Np Mössbauer measurements on NpFeAsO. The Np atoms were found to occupy only one crystallographic site. The value of the isomer shift (δ ∼ 9.1 mm s−1 versus NpAl2) indicates a 5f4 electronic configuration (Np3+ ions). The magnetic ordering of the Np sublattice below 60 K is established and the saturated ordered magnetic moment is determined to be 1.73μB at 3.6 K. The unique set of hyperfine parameters exclude a modulated...

The effect of surfactants on activated sludge process
PublicationBadano wpływ anionowego surfaktantu (SDBS) na proces biologicznego oczyszczania ścieków metoda osadu czynnego. Stwierdzono, że stężenie SDBS powyżej 50 mg/l miało wyraźny wpływ na przemiany związków azotu i fosforu w czasie oczyszczania ścieków. Wpływ badanego związku na usuwanie związków organicznych (wyrażonych jako ChZT) był mniej wyraźny.

Doppler effect in the CW FM sonar
PublicationWhen sonars are used for military purposes they have to ensure unobtrusive operation, a feature that can be potentially secured by 'silent sonar' or continuous wave frequency modulation sonars (CW FM sonars). The article presents how these sonars operate and identifies the relations between their parameters. The Doppler effect and its impact on the CW FM sonar are studied to identify how it affects the sonar's parameters. The results...

Transversal Pressure Effect in Circulative Separators
PublicationPrzeanalizowano podobieństwa i różnice między podstawowymi kategoriami separatorów odśrodkowych (wirówki, cyklony, separatory wirowe). Zaproponowano model pola prędkości w separatorze. Wyznaczono rozkład ciśnienia i obliczono siłę dryfu poprzecznego (efekt poprzecznej zmiany ciśnienia). Przeprowadzono pomiary ciśnienia w separatorze laboratoryjnym, uzyskując pozytywną weryfikację przedstawionego modelu.

The effect of processing on the safety and nutritional value
PublicationAgricultural crops as well as animal food raw materials are usually somehow processed before being used by humans. Processing should make them more useful, increase their safety and nutritional value, extend the shelf life, and modify the sensory properties. However, changes and interactions of various compounds in the conditions of processing may generate products toxic or otherwise unsafe for the human organism. The food industry...

Improvement of the Chimney Effect in Stack Ventilation
PublicationThe article is focused on the airflow in a ventilation system in a building. The work examines the methods which enhance the chimney effect. In this paper, three cases with different chimneys were analyzed for the full-scale experiment. These cases were characterized by different geometrical and material parameters, leading to differences in the intensity of the ventilation airflow. The common denominator of the cases was the room...

Effect of glycosoaminoglycans on reconstitution of collagen fibrils
PublicationCelem pracy było sprawdzenie efektywności rekonstytucji fibryli i włókien z roztworu kwasu solnego kolagenu skór bydlęcych pod wpływem glikozaminoglikanów (GAGs), wydzielonych z tchawic bydlęcych, w układach o sile jonowej w zakresie 0-0,7 oraz pH 3-8. Stwierdzono, że dodatek GAGs do roztworu kolagenu powoduje natychmiastowe powstawanie włókien, których ilość wzrasta wraz z ilością dodanych glikozaminoglikanów i stężeniem kolagenu....

Effects of dispersion on predicting longitudinal concentration profiles in activated sludge reactors
PublicationW pracy przedstawiono wpływ dyspersji na prognozowanie stężeń azotu amonowego w komorach osadu czynnego w oczyszczalni ścieków Gdańsk-Wschód. W tym celu wykorzystano jednowymiarowe równanie adwekcji-dyspersji z członem źródłowym (szybkością nitryfikacji). Współczynnik dyspersji został wyznaczony na podstawie pomiarów znacznika fluoroscencyjnego. Model został zweryfikowany w oparciu o pomiary stężeń azotu w 6 sekcjach komory tlenowej...

Sawing frozen wood with narrow kerf saws: Energy and quality effects.
PublicationOpór skrawania zależy podczas przecinania nie tylko od wilgotności drewna lecz również od jego temperatury. W pracy przedstawiono wyniki badań eksperymentalnych przecinania drewna sosnowego zmrożonego na pilarce ramowej wielopiłowej. Dla porównania wykonano również testy dla drewna o temperaturze pokojowej. Czynnikami badanymi były: moc skrawania, dokładność przecinania w postaci grubości elementów, a także chropowatość powierzchni....

Phytoecdysteroid containing plants – a source of bioactive compounds with potential anticarcinogenic effects
PublicationEcdysteroids are a group of steroids synthesized in inver- tebrates as molting hormones and also in some plants as secondary metabolites acting as a defense against parasites. These compounds do not naturally occur in mammals and are not structurally related to mammalian steroid hor- mones, consequently do not activate mammalian hormone receptors. Ecdysteroids exhibit very low toxicity to mam- mals and to date no serious side effects...
