AB  - Brahiterapijski uređaji sa izvorima velike aktivnosti (> 370 GBq) postavljaju se u posebne zaštitne bunkere, debljine zaštitnog betonskog zida oko 70 cm, što zahteva opsežnije građevinsko-tehničke radove i povećava cenu izrade (preko 100.000 Eura). Da bi se prevazišao problem ograničenog prostora unutar odeljenja brahiterapije, predlažemo izradu „brahiterapijske komore“ koja bi bila smeštena u aplikacionoj sali minimalne površine 30 m2. Komandni pult brahiterapijskog uređaja bi se nalazilo u parapetom/paravanom odvojenom delu sale. Brahiterapijska komora, pojedinačnih dimenzija (V x Š) oko 2 m, u obliku ćiričnog slova P (П), izrađuje se od olovnih ploča debljine 5 cm. Sa jedne strane komore (ulaz za pacijenta) navlačiće se pokretni/motorizovani paravan (debljine zida: 5 cm; dimenzija V x Š oko 2,3 m). U toku zračenja pacijent i uređaj se nalaze u komori. Cena izrade ove brahiterapijske komore sa pripadajućim elementima ne bi prelazila cenu izrade klasičnog brahiterapijskog bunkera.
AB  - Brachytherapy units with high activity sources (> 370 GBq) are placed in special protective treatment rooms, with concrete wall thickness of about 70 cm, which requires more extensive construction and technical works that increases the cost of production (over 100.000 Euros). In order to overcome the problem of limited space within the brachytherapy department, we propose construction of a "brachytherapy chamber" that would be located in the application teatre with a minimum area of 30 sqm. The control unit would be located in a separated part of the treatment room. The brachytherapy chamber, with an individual dimensions (H x W) of about 2 m, in the shape of the Cyrillic letter P (П), is made of lead plates 5 cm thick. On one side of the chamber (patient entrance) a movable/motorized screen (wall thickness: 5 cm; dimensions HxW each approx. 2.3 m) will be constructed. During radiation, the patient and theunit are in the chamber. The construction cost of this brachytherapy chamber with associated elements would not exceed the cost of making a classic brachytherapy treatment room.

AB  - Two zirconia samples were prepared by precipitation from aqueous zirconium oxychloride and zirconyl sulfate solutions with potassium hydroxide. The prepared zirconia samples were amorphous. The pH(pzc) values of the zirconia samples, determined in NaCl and NaNO3 solutions, were 6.6 +/- 0.1 and 6.9 +/- 0.1, respectively. After prolonged hydration of zirconia in doubly distilled water, the pH(pzc) decreased to 4.7 +/- 0.3. Crystallization into tetragonal (metastable) + monoclinic zirconia appeared at 691 K. Above 873 K, the tetragonal metastable phase changes to a monoclinic phase. It was shown that crystallite sizes of zirconia treated at 673-1273 K increased from 9.5 to 40.5 nm, respectively. The increase in temperature from 385 to 1070 K increased the pH(pzc) of zirconia samples from 6.6 to 9.0, respectively.
