Characterization and properties of barium bismuth titanate
(Faculty of Technology, University of Novi Sad, 2009)
BaBi4Ti4O15 (BBiT) was prepared from stoichiometric amounts of BaTiO3 (BT) and Bi4Ti3O12 (BIT) obtained
via mechanochemical synthesis. Mechanochemical synthesis was performed in air atmosphere in a planetary
ball mill. ...
Population viability analysis and potential of its application to Danube sturgeons
(Srpsko biološko društvo, Beograd, i dr., 2009)
Sturgeon species in the Danube River basin have experienced severe decline. Besides overexploitation, habitat loss, and pollution, they are further endangered by lack of efficient policy and management, as well as by serious ...
Improved total conductivity of nanometric samaria-doped ceria powders sintered with molten LiNO3 additive
(Elsevier, Amsterdam, 2009)
Nanometric 20% molar Sm-doped ceria (SDC20) powders were synthesized by co-precipitation in the presence of N, N, N', N' tetramethylethylendiamine (TMEDA). SDC20 powders were sintered using lithium nitrate salt in various ...
Decline in the Index of Biotic Integrity of the Fish Assemblage as a Response to Reservoir Aging
(Springer, Dordrecht, 2009)
The fish assemblage from reservoir Medjuvrsje was monitored over the 1955-2000 period. The Medjuvrsje Reservoir is one of the oldest Serbian reservoirs formed in 1953. Ichthyofauna was sampled in 1955, 1984, 1991 and 2000. ...
Acipenser sturio and Acipenser nudiventris in the Danube - extant or extinct?
(Wiley, Hoboken, 2009)
The presence of Atlantic sturgeon (Acipenser sturio) and ship sturgeon (Acipenser nudiventris) in the Danube has been known through only occasional, chance sightings; significant uncertainty remains as to whether these ...
Temporal analysis of electroretinographic responses in fishes with rod-dominated and mixed rod-cone retina
(General Physiol And Biophysics, Bratislava, 2009)
Photoreceptor content of fish retinas could be accessed by comparative electroretinographic (ERG) studies using flickering light stimuli that could separate rod-mediated vision where critical flicker frequency (CFE, frequency ...

(Wiley-Blackwell, Hoboken, 2009)
In Europe Phytophthora ramorum has been reported on a range of
ornamentals as well as on a limited number of tree species in at least in 11
countries: UK, Spain, Belgium, Germany, the Netherlands, Italy, France,
Switzerland, ...
A wet-chemical route for the preparation of Ni-BaCe0.9Y0.1O3-delta cermet anodes for IT-SOFCs
(Elsevier, Amsterdam, 2009)
Nano-sized BaCe0.9Y0.1O3 - delta (BCY10) protonic conductor powders were used to prepare Ni-BCY10 cermets for anode-supported intermediate temperature solid oxide fuel cells. A new wet-chemical route was developed starting ...
Seasonal changes in condition, hepatosomatic index and parasitism in sterlet (Acipenser ruthenus L.)
(Scientific Technical Research Council Turkey-Tubitak, Ankara, 2009)
Measurements of biomarker responses in fish from contaminated sites could provide valuable data for environmental risk assessment. Biomarkers are sensitive to both environmental pollution and confounding factors that are ...
Potential role of hydrogen peroxide and melanin in the cold hardiness of Ostrinia nubilalis (Lepidoptera: Pyralidae)
(Czech Acad Sci, Inst Entomology, Ceske Budejovice, 2009)
The aim of this study was to investigate the relationship between antioxidant enzymes and reactive oxygen species production in diapausing larvae of the European corn borer, Ostrinia nubilalis (Lepidoptera: Pyralidae) kept ...
