The proposed BPF is configured using two microstrip feedlines, semi- circular SIW cavities, capacitive slots, and inductive vias. The circular cavity is bisected into two halves, with the two copies thereof being cascaded. Two bisected and cascaded structures obtained this way are subsequently connected...

  Określono poziomy stężeń składników śladowych obecnych w próbkach rosy zebranych na terenach wyraźnie różniących się pod względem położenia geograficznego jak również poziomem antropopresji. Próbki rosy były zbierane na terenie ośmiu stacji pomiarowych w cyklu dobowym w okresie od sierpnia 2004 do listopada 2006 roku. W zależności od położenia miejsc zbierania próbek oraz charakteru tła emisji zanieczyszczeń dokonano podziału na...

  Airport runoff can contain high concentrations of various pollutants, in particular polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs), the environmental levels of which have to be monitored. Airport runoff water samples, collected at the Gdańsk-Rębiechowo Airport from 2008 to 2009, were analysed for PAHs and PCBs by gas chromatography. The aromatic fractions were separated by liquid-liquid extraction...
