Plutonium, americium, 90 Sr and 137 Cs in bones of red fox (Vulpes vulpes) from Eastern Poland
No full text90Sr, 238,239+240Pu, 241Am and 137Cs activity concentrations are presented in the jaw bones of red fox (Vulpes vulpes) from eastern Poland. The short description of the applied radiochemical method is presented. Activity concentrations for 90Sr ranged between 2.2±0.7 and 41.4±4.7 Bq/kg (aw = ash weight). Average results for plutonium and americium are on the level of 10 mBq/kg (aw). No clear relationship was observed among the radionuclide concentrations. The samples analyzed do not show elevated contamination levels when compared with results of bones of small animals (rodent or insectivorous mammals) determined previously, so no accumulation of bone seeking isotopes on higher step of food-chain is concluded
Elevated plutonium and americium content in skulls of small mammals
No full textIt has been found that in skull bones of small mammals have significantly higher Pu and Am concentrations than ever found in bones of any other species in areas contaminated by global fallout. Since there was no difference between skulls of rodents and insectivorous, an explanation is proposed that the contamination takes place by the inhalation of Pu and Am tiny soil particles
40K, 137Cs, 90Sr, 238,239+240Pu and 241Am in mammals' skulls from owls' pellets and owl skeletons in Poland
No full textSkulls of small mammals belonging to two species of rodents and three species of insectivores collected in Eastern Poland were the subject of the present investigation. The skulls were separated from owl pellets. Activities of 40K, 137Cs, 90Sr, 238,239+240Pu and 241Am were determined by means of gamma spectrometry as well as liquid scintillation spectrometry or alpha spectrometry along with relevant radiochemical procedures. A detailed description of the procedures is provided. The research was supplied with the analysis of three skeletons of owls. No measurable difference between the skulls of rodents and insectivorous animals with regard to activity of any of the examined radionuclides was found. No accumulation effect in the owl skeletons was detected. Though measured activities of 137Cs and 40K for the skulls were of the same magnitude as those found previously for large wild herbivorous animals from typical locations in Poland, those for 90Sr were even lower than previously determined. A big difference was found for activities of plutonium and americium isotopes. Their mean activities were higher by an order of magnitude when compared to the examined previously values. The maximum 239+240Pu activity was equal to 97.5±7.7 mBq/kg, with 65% of it originating from global fallout. Relatively high content of transuranic elements found for rodents and insectivorous mammals seems to be unrelated to their feeding habits and should rather be attributed to the living conditions. It is suggested that small mammals, together with tiny soil particles present in mid-soil living tunnels, can inhale the transuranic elements
90Sr, 241Am and plutonium in Barn Owl skeletons (Tyto alba Scop.) from southeast Poland
No full textNumerous studies concerned with accumulation of several various groups of chemical compounds have been performed on Bam Owls (Tyto alba Scop.). But up to now we have no data about concentrations of radionuclides in their tissues. However, in Europe a large part of the breeding range of this species might have received fallout from Chernobyl. Nine skeletons of Barn Owls collected in 1999-2002 in southeastern Poland were analyzed for 90Sr, 241Am and plutonium. The results revealed 239+240Pu (< 0.004 Bq/kg - 0.051 ± 0.007 Bq/kg ash weight), 241Am (< 0.02 Bq/kg - < 0.06 Bq/kg ash weight) and 90Sr (9.7 ± 0.9 Bq/kg - 46.8 ± 3.6 Bq/kg ash weight) concentrations to be similar to those observed in the prey species; therefore, the conclusion is that no accumulative effect has been seen
The importance of rural parks for the occurrence of the Rook Corvus frugilegus in the eastern part of the Lublin region (E Poland) – ecological and social factors
No full textKitowski I.: The importance of rural parks for the occurrence of the Rook Corvus frugilegus in the eastern part of the Lublin region (E Poland) - ecological and social factors. Ekologia (Bratislava), Vol. 32, No. 3, p. 283-298, 2013. This study deals with the population size and the distribution of breeding colonies of the rook in rural parks in the eastern part of the Lublin region (Eastern Poland). Large parks with a large number of tree species were appropriate sites for larger rookeries. Small, degraded parks, with few species of trees, were used by smaller rookeries, which showed tendencies to disappear more quickly. Small colonies were irrevocably abandoned if disturbed by man, whereas large ones had a very high reoccupation potential, even after a few years. Unfortunately, ownership changes concerning rural parks in Eastern Poland may endanger the rookeries located there
Gamma-emitters 90Sr, 238,239+240Pu and 241Am in bones and liver of eagles from Poland
No full textThe present study focused on analyzing samples of bones, livers and kidneys of European white-tailed eagles (Haliaëtus albicilla) and lesser-spotted eagle (Aquila pomarina). Bone samples were collected for both species, from 7 and 2 individuals, respectively, whereas liver and kidney samples for white-tailed eagle species only, 2 and 1 individuals, respectively. The samples were analyzed for the presence of gamma-emitters and then for 90Sr, 238Pu, 239+240Pu and 241Am. The applied radiochemical method is presented. Activity concentration in ashen bones (600 °C) for 90Sr ranged from 4.6±1.2 to 31.0±2.5 Bq/kg, for 239+240Pu from <1.7 to 21±4 mBq/kg, for 238Pu from <2.7 to 6.5±1.3 mBq/kg and for 241Am from <1.2 to 6.5±4.4 mBq/kg. Relatively high 239+240Pu activity concentration of 78±9 mBq/kg (for fresh weight) was recorded in a single kidney sample. The liver samples showed activities of magnitude at least one order lower. No clear correlations were found between the activities of different radionuclides

No full textIzaak Gotfryd Goedtke (1691-1765). Z badań nad studiami uniwersyteckimi i karierami prawników doby oświecenia.
No full textOsoba Goedtkego jest dobrze znana nie tylko niemieckiej, ale także polskiej (przede wszystkim pomorskiej) historiografii. Pogłębione kwerendy źródłowe, zwłaszcza w Archiwum Państwowym w Bydgoszczy (w zespole akt miejskich Chojnic), pokazują jednak, że obraz Goedtkego wciąż nie jest pełny i możemy rozwinąć go o wiele nowych, a jednocześnie niezwykle ciekawych kwestii. Warto zatem prześledzić losy jego życia, szczególnie w kontekście badań nad studiami uniwersyteckimi protestanckiej młodzieży z pruskich miasteczek, które nie znalazły dotychczas szerszego zainteresowania w historiografii , jak i późniejszych losów pochodzących z nich absolwentów
The ATLAS experiment on-line monitoring and filtering as an example of real-time application System monitoringu i filtracji eksperymentu ATLAS jako przykład aplikacji czasu rzeczywistego /
No full textTyt. z nagłówka.Pozostali autorzy artykułu: Tadeusz Szymocha, Włodzimierz Funika, Jacek Kitowski, Renata Słota, Kazimierz Bałos Łukasz Dutka, Krzysztof Guzy, Tomir Kryza, Jan Pieczykolan.Bibliografia s.86.Dostępny również w formie drukowanej.ABSTRACT: The ATLAS detector, recording LHC particles' interactions, produces events with rate of 40 MHz and size of 1.6 MB. The processes with new and interesting physics phenomena are very rare, thus an efficient on-line filtering system (trigger) is necessary. The asynchronous part of that system relays on few thousands of computing nodes running the filtering software. Applying refined filtering criteria results in increase of processing times what may lead to lack of processing resources installed on CERN site. We propose extension to this part of the system based on submission of the real-time filtering tasks into the Grid. STRESZCZENIE: Detektor ATLAS, rejestrujący zderzenia protonów rozpędzanych w zderzaczu LHC, będzie generował przypadki o rozmiarze 1.6MB z częstotliwością 40MHz. Aby wyselekcjonować bardzo rzadko występujące przypadki z interesującymi oddziaływaniami fizycznymi, konieczne będzie zastosowanie wydajnego systemu filtracji (trigger). Część asynchroniczna takiego systemu wykorzystuje kilka tysięcy komputerów, na których wykonywane jest oprogramowanie filtrujące. Zwiększenie selektywności systemu wymaga zwiększenia czasu procesowania, co może doprowadzić do wyczerpania zasobów komputerowych zainstalowanych w CERN-ie. Proponujemy rozszerzenie tej części systemu poprzez umożliwienie wykonywania oprogramowania filtrującego w czasie rzeczywistym na komputerach w środowisku gridowym. KEYWORDS: high energy physics, real-time procesing, trigger system, remote farms. SŁOWA KLUCZOWE: fizyka wysokich energii, przetwarzanie w czasie rzeczywistym, system filtracji, zdalne farmy
