Abstract

Technologia przepuszczalnych reaktywnych barier (PRB) należy do metod remediacji wód gruntowych. W technologii tej zanieczyszczenia usuwane są bezpośrednio w warstwie wodonośnej poprzez przepływ skażonego strumienia wód gruntowych przez wypełnioną odpowiednim materiałem (aktywnym) barierę aktywną. W artykule przedstawiono problemy związane z tworzeniem się osadów w żelazie metalicznym stosowanymjako material aktywny technologii PRB. Osady te mogą zmniejszać aktywność materiału i jego zdolność filtracyjną. Tworzeniu się osadów mogą towarzyszyć zmiany pH, potencjału redox oraz stężenia tlenu. Zmiany te były obserwowane w badaniach laboratoryjnych przedstawionych w artykule. Ponadto w artykule przedstawiono i udowodniono następującą zasadę: aby zwiększyć skuteczność działania typu Funnel-and-Gate technologii PRB przez zwiększenie szerokości strefy oczyszczania, stosunek współczynnika filtracji materiału aktywnego do współczynnika filtracji warstwy wodonośnej (k,,,/k,ą) powinien przyjąć wartość 6. Ze względu na tworzenie się osadów w żelazie metalicznym, które mogą zmniejszyć jego zdolność filtracyjną, założono jednak, iż stosunek ten powinien wynosić I O. Wartość ta daje pewność, że zmniejszenie się wartości współczynnika filtracji materiału aktywnego na skutek tworzenia się osadów, nie wpłynie w znaczący sposób na szerokość strefy oczyszczania. Przedstawione rozwiązanie może zapewnić skuteczne i długotrwale oczyszczanie wód gruntowych w typie Funnel-and-Gate technologii PRB.

Abstract

The Main Commission for the Investigation of German Crimes in Poland was brought to life in March 1945 as a central institution entitled to conduct investigations and collect evidences of war crimes committed during the German occupation of Poland (1939-45). In 1949, the Commission was renamed as the Main Commission for the Investigation of Hitlerite Crimes in Poland, in order to mark the propagandist division between the ‘progressive’ and ‘antifascist’ East Germany and the ‘revisionist’ West Germany; yet, its activities were at the same time put on halt. In 1958, West German authorities created the Central Office of the State Justice Administrations for the Investigation of National Socialist Crimes, based in Ludwigsburg. The first, semi-official, contacts between these two institutions were inaugurated in 1960, despite the lack of official diplomatic relations between Warsaw and Bonn at that time. The venue of the contact was the Polish Military Mission in West Berlin, where the prosecutors from Ludwigsburg could get acquainted with documents from the Commission’s archive.

Abstract

What we intend to do in this short essay is to consider part of the epistolary of Rebora as a literary object, an object that follows the condition of poetry hand in hand (at least in certain moments) and that often goes beyond it precisely at the level of daring formal and semantic. In evaluating the epistolary under the literary aspect, in its creativity so similar to writing in verse, our pourpose is to demonstrate how at the basis of Rebora’s expressiveness (or expressionism) there is a powerful endogenous drive, and that his disorder is psychological rather than cultural, or “stylistic”.

Abstract

Background: Despite advanced research and great progress in understanding the chronic pancreatitis (CP) pathogenesis, no current causal treatment for the condition is available. For preclinical studies, the existence of a well-characterized CP animal model is essential.
The aim of the study was to assess the impact of chronic pancreatitis on the antioxidant enzymes activity in rat blood serum and on the level of glutathione (intracellular antioxidant) in rat pancreas.
Methods: The experiments were carried out on the Wistar Kyoto rats in two groups: control and study group (CP), in which chemical induction of pancreatitis with dibutyl dichloride was performed. Serum enzyme activities of amylase, lipase, catalase and superoxide dismutase were analyzed. The levels of the following biochemical parameters were also investigated: total protein, albumin, calcium, magnesium, and triglycerides. Levels of low-molecular-weight thiols: reduced (GSH) and oxidized (GSSG) glutathione, were determined in pancreatic homogenates.
Results: Histopathological imaging of rat pancreatic parenchyma with induced inflammation confirmed focal lymphocytic interstitial chronic pancreatitis with fibrosis features and mild parenchymal atrophy, as well as pancreatic islets degeneration. In the CP group, we observed a statistically significant decrease in serum amylase and lipase activities and in total protein/albumin levels. Also, the elevated catalase activity was registered. In CP rats’ tissues, we observed a 15-fold reduction in GSH levels. The other examined parameters remained unchanged. Clinically relevant are hypoalbuminemia and a moderate decrease in lipase activity. The described changes are most probably indicative of the impaired exocrine pancreas function, however without organ failure features.
