Most of the 68 wells uncovered on the single-layer horizontal settlement lying adjacent to the tell at Polgár-Csőszhalom did not contain any unusual finds. A few wells, however, yielded remarkable assemblages that can be interpreted as intentional, structured depositions. One of these was Feature 272, a well lying some 80–90 m from the one-time water shore, which contained a remarkably high number of vessels, most of which were lavishly ornamented. The form and the contents of this well suggest that it represents the archaeological imprint of a series of ritual acts performed according to a set of strict rules and the structured deposition of the ritual paraphernalia.

Abstract  

The monthly variation of selenium concentration in atmospheric particulate material of Ankara was investigated. The selenium concentrations in possible pollution source materials like coal, fuel oil and their bottom and fly ashes were determined to obtain the percent transference of selenium into the atmosphere. Instrumental thermal neutron activation analysis and atomic absorption spectroscopy were applied for the analysis of selenium in the samples. Selenium enrichment factors with respect to the fuels, soil of Ankara and crustal material were also calculated. Atmospheric selenium concentration is found to increase during winter months and the main cause of this increase is the emission of selenium into the atmosphere due to fuel combustion.

Abstract  

NAA has been applied to determine the concentration of K, As, Se, Zn, Cr, Cs, Fe, Co, Sb, Ni and Ca in sediments and a macroalgae species collected from the Küçükçekmece Lagoon and Marmara Sea. The lagoon sediment showed higher metal levels than the sea sediment. The metal contents in algae species are not changed significantly between months and sampling sites except Zn and Cr. The profile of the lagoon sediments was also investigated.

Abstract  

In ambient air, arsenic to selenium ratio (As/Se) is generally found to be less than 1, except in areas influenced by specific point sources, such as Cu smelters. However, the annual average of this ratio is found to be much higher than unity in Turkey. This finding is rather unique and may provide a marker for air masses influenced by the coal-related emissions in Turkey.

Abstract  

Cesium-137 concentrations in red, brown and green algae have been studied for the calculation of natural depuration rates. The algae species were collected from the same population of the Black Sea stations during the period of 1986–1995. The natural depuration rates are estimated as biological half-lives. The pattern of depuration results represented by a single component for each algae division. The biological half-lives of137Cs in red (Phyllophora nervosa), green (Chaetomorpha linum) and brown (Cystoceira barbata) algae are estimated to be 18.5, 21.6 and 29.3 months, respectively.137Cs and40K activity levels and their ratios in algae species in two stations in Black Sea region of Turkey have been determined during the period of 1990–1995. The results showed that the Sinop region was more contaminated than the ile region on the Black Sea coast of Turkey from the Chernobyl accident.

Abstract  

During the periods of 1997–1998, macroalgae, sea snail, mussel, fish and sediment samples were collected from different stations at Turkish Black Sea coast in order to determine activity levels of 137Cs radionuclide. 137Cs activity in the tested algae species and in soft parts of mussel and sea snail, were found to be below the lower limit of detection. On the other hand, the 137Cs concentration in muscle tissue of the sea snail samples were found from 6±2 to 19±7 Bq·kg–1 dry weight. The range of the 137Cs concentration in anchovy fish muscles were found between 4±2 – 10±5 Bq·kg–1 dry weight. The 137Cs concentration in the whiting fish muscle was found below the lower limit of detection. However, this activity found in shad fish muscle to be 25±10 Bq·kg–1 dry weight. The concentrationsof the 137Cs activity in the sediment samples proved that the eastern region of the Black Sea was affected by Chernobyl at a very high degree compared with the western part. The measured 238U, 232Th and 40K concentrations in sediment samples are within the range of the cited values in the previous works at the Turkish Black Sea coast.

Az emlékművek fontos szerepet játszanak életünkben. A történeti városok a huszadik században jelentős átalakuláson mentek keresztül. Ezzel a meglévő emlékművek történelmi szerepe felértékelődött. Az építészeti irányzatok, elvek és módszerek, melyek korunk rekonstrukciójában is fontos szerepet játszanak, csak alapos és tudományos mélységű tapasztalatok mentén születhetnek meg. A hazai XVIII. és XIX. századi emlékművek döntő többsége Budapesten található. A megváltozott környezet és építési technológia a műemlékvédelem új szempontjait teremtik meg. Az Építészettörténeti és Műemléki Tanszék egy csoportja, Dr. Istvánfi Gyula vezetése alatt, egyes emlékművek helyreállítása során több fontos szakmai következtetésre jutott. A cikk négy különböző alaptípussal foglalkozik: Szentháromság-emlék a XVIII. századból, a Danubius kút a XIX. századból, a Szent István-emlék és a Millenniumi emlékmű a XIX. és XX. század fordulójáról, valamint szó esik a XIX. században létesített Deák-szobor problémáiról is. A felmerült problémák részben egymással megegyezőek, részben pedig sajátosak. Mindegyik esetben fontos a jelenlegi műszaki és társadalmi környezettel való összevetés. A példák során szerzett tapasztalatok eredményesen használhatók más helyreállítás során is.
