Aspects of conservation of wetland birds within the protected natural objects in Serbia
(European Science FoundationInstitute of Avian Research, 2005)
Bird species such as mergansers, grebes, ducks, geese and swans spend winter on the larger rivers in Serbia, primarily on the Danube. There is also a large number of other wetland birds (herons, storks and ibises) that are ...
Characterization of Barium Titanate powders Prepared by polymeric Precursors Method
(COST Action 539 - ELENA NanoMetro Workshop, Leysin, January 31,2008, 2008)
Barium titanate is the first ferro-electric ceramics and good candidate for variety applications due to its excellent dielectric, ferroelectric and piezoelectric properties. Barium titanate is a member of large family of ...
Wintering Waterfowl of Serbian portion of Danube River: counts 1999-2003
(AKDENIZ UNIVERSITY – ANTALYAHACETTEPE UNIVERSITY – ANKARA, 2004)
IWC (International Water Bird Census) represents the greatest survey program of biodiversity in the world that deals with the birds of wetland habitats. Information that is gathered by census method of IWC in six Eurasian ...
Roll and importance of accumulation lake Gruža in bird migration
(AKDENIZ UNIVERSITY – ANTALYAHACETTEPE UNIVERSITY – ANKARA, 2007)
Artificial accumulation Lake Gruža fills the depression of the Knićko Field, situated between the mountains Gledićke and Kotlenik. It was formed mostly in order to provide water supply for industry and residential of the ...
Sezonska horizontalna distribucija i abundancija vrsta familija Temoridae u Bokokotorskom zalivu
(Srpsko društvo za zaštitu voda, 2008)
U Bokokotorskom zalivu registrovane su dvije vrste Copepoda iz familije Temoridae: Temora stylifera (Dana, 1849) i Temora longicornis (Müller 1792). U radu dajemo podatke o horizontalnoj distribuciji i abundanciji ovih ...
Microstructure and Dielectric Properties of Lanthanum Doped Barium Titanate
(6th Workshop COST 539, 23-25. February 2009, Madrid, Spain, Programme and book of abstracts, p 64-65, 2009)
Barium titanate has a special place in the group of ferroelectric perovskites because it can be formulated in a large number of systems and solid solutions that provide a wide range of various applications. The perovskite ...
DIELECTRIC INVESTIGATIONS OF BARIUM TITANATE DOPED WITH DEFERENT CONCENTRATION OF LANTHANUM OR ANTIMONY
(Final Workshop COST 539, 28-30 October 2009, Aveiro, Portugal, Programme and book of extended abstracts, 142-143., 2009)
The dielectric properties of barium titanate doped with different concentration
lanthanum or antimony are investigated. There are samples with 0.3 mol%, 0.5 mol%
lanthanum and 0.1 mol%, 0.5 mol% antimony concentrations. ...
DIELECTRIC INVESTIGATION OF BARIUM TITANATE WITH 0.5% ANTIMONY
(6th Workshop COST 539, 23-25. February 2009, Madrid, Spain, Programme and book of abstracts, p 64-65, 2009)
Barium titanate (BaTiO:) is versatile electroceramic that exhibits high permittivity
(e') making it desirable material for capacitor and others widespread applications. On
heating, it undergoes a ferroelectric/paraelectric ...
Influence of lanthanum doping on properties of BaTiO3 prepared from organometallic complex
(5th Workshop COST 539, 1 September 2008, Manchester, UK, abstracts and CD proceedings, 2008)
Barium titanate is the first discovered ferroelectric ceramic and one of the most widely used material for various applications. Doping of BaTiO3 (BT) ceramics is very important for obtaining very interesting characteristics ...
