Capacity Transforming challenges into opportunities
PublikacjaThe Urban Initiative Laboratory (UIL) aims to upgrade the smart city concept in Gdańsk by introducing the Food-Water-Energy (FWE) nexus to the city. It was agreed in the CRUNCH international consortium that projects on different scales would be implemented in the individual countries to test the Integrated Decision Supportive system platform, which would, in principle, concern urban scale. The regular urban scale was to be researched...

Bearing capacity for random subsoil.
PublikacjaW pracy zaproponowano modyfikację metody charakterystyk bazującej na stochastycznej metodzie różnic skończonych. Podejście takie pozwoliło na uwzględnienie przestrzennej zmienności podłoża gruntowego przy ocenie nośności granicznej ławy fundamentowej posadowionej na losowym podłożu. Przeprowadzono analizę wpływu dyskretyzacji ośrodka gruntowego na rozwiązanie oraz rozpatrzono jego zbieżności.

Organic and conventional kiwifruit myths versus reality: antioxidant, antiproliferative and health effects
PublikacjaComparison between organic and conventional kiwifruit cultivars ''Hayward'' and ''Bidan'', which was done by four redical scavenging assays, ESI-MS, and DSC measurements, showed significant differences between cultivars. Such results were not estimated in kiwifruit growing under organic and conventional conditions. The extraction of bioactive compounds was done by two different methods: sequential extraction with ethyl acetate...

Coffee silverskin as a potential bio-based antioxidant for polymer materials: Brief review
PublikacjaCoffee silverskin is one of the by-products generated by the coffee industry. Although it is not the most burdensome one, because it stands only for ~4.2 wt % of coffee, it seems like an auspicious raw material for industrial processes. Coffee silverskin is characterized by a relatively low moisture content of ~5–7%, so it often does not require quite energy-consuming drying processes. The chemical composition of coffee silverskin,...

Characterization of white cabbages from different cultivations by isothiocynates content and antioxidant activities
PublikacjaBadania epidemiologiczne wskazują, że wraz z zwiększeniem spożywania kapusty maleje ryzyko zachorowania na niektóre nowotwory. Mechanizmy przeciwrakotwórczego działania nie są do końca wyjaśnione, jednak wiele badań przeprowadzonych z wykorzystaniem zwierząt i ludzi sugeruje, że substancje występujące w tych roślinach, szczególnie izotiocyjaniany (ITC) modulują aktywność enzymów I i II fazy. Aktywność przeciwutleniająca jest innym...

Novel ABTS-dot-blot method for the assessment of antioxidant properties of food packaging
PublikacjaThe new ABTS-dot-blot method for the direct determination of antioxidant activity of active packaging that is in contact with foodstuffs has been developed. The usefulness of the new method was verified with the use of agarose, pork gelatin, bacterial cellulose and cellulose-chitosan films with incorporated standard antioxidant – Trolox or plant phytochemicals derived from three types of berry juices (chokeberry, blue-berried honeysuckle,...

Antioxidants: a premature scientific hypothesis that reshuffled the traditional food pyramid
PublikacjaAntioxidants present in substantial amounts in foods, plant-based products in particular, have been suggested as chemopreventive agents that can curb the development of undesirable health effects caused by oxidative stress simply by enriching diet in such compounds. This idea has been enthusiastically accepted by consumers, as well as food and pharmaceutical industry, and created great demand for products containing antioxidant...

Comparison of bioactive compounds, antioxidant and antiproliferative activities of Mon Thong durian during ripening
PublikacjaCelem przeprowadzonych badań było oszacowanie zmian zawartości związków odżywczych, związków bioaktywnych, kwasów tłuszczowych oraz przeciwutleniaczy w owocach duriana w trakcie różnych etapów procesu dojrzewania. W badaniach wykorzystano testy CURRAC, DPPH, ABTS i FRAP. Stwierdzono, że całkowita zawartość polifenoli, flawonoidów, kwasu askorbimowego, tanin oraz poziom aktywności przeciwutleniającej jest dla owoców niedojrzałych,...

Assessment of Lipophilicity Indices Derived from Retention Behavior of Antioxidant Compounds in RP-HPLC
PublikacjaReverse phase high pressure liquid chromatography was employed in order to evaluate the lipophilicity of antioxidant compounds from different classes, such as phenolic acids, flavanones, flavanols, flavones, anthocyanins, stilbenes, xantonoids, and proanthocyanidins. The retention time of each compound was measured using five different HPLC columns: RP18 (LiChroCART, Purosphere RP-18e), C8 (Zorbax, Eclipse XDBC8), C16-Amide (Discovery...

The effect of convective heating and microwave heating on antioxidant enzymes in pooled mature human milk
PublikacjaThe effects of convective and microwave heating at constant temperature (62.5, 66 and 70 °C) on the activity of antioxidant enzymes (superoxide dismutase, SOD; catalase, CAT; glutathione peroxidase, GPx) in pooled mature human milk were compared. Activities of the enzymes were determined using spectrophotometric kits. Activity of GPx decreased significantly in the first stage of heating when milk samples were warmed to pasteurisation...

A simple test for quantum channel capacity
PublikacjaBased on state and channel isomorphism we point out that semidefiniteprogramming can be used as a quick test for nonzero one-way quantum channelcapacity. This can be achieved by searching for symmetric extensions of statesisomorphic to a given quantum channel. With this method we provide examplesof quantum channels that can lead to high entanglement transmission but stillhave zero one-way capacity, in particular, regions of symmetric...

EFFECT OF ANTIOXIDANTS ON THE STABILITY OF PITCH- BASED POLYMER TO THERMO-OXIDATIVE ACTION
PublikacjaThe influence of stabilizers – hydrogen donors – on the processes of thermooxidative destruction of pitch-based polymer has been investigated. It is shown that Irganox has not stabilizing effect on pitch-based polymer and melamine slightly retards the destructive process. A mixture of melamine and Irganox exhibits synergetic stabilizing effect and at the optimum ratio it can be used to prevent unwanted thermooxidative processes...
