Variation in Nutritional Quality and Chemical Composition of Fresh Strawberry Fruit: Combined Effect of Cultivar and Storage
(Springer, Dordrecht, 2015)
Bioclimatic air ionisation system (BI) works by neutralising air pollutants and microorganisms by means of oxidation with "activated oxygen". We investigated the effects of storage on changes in weight loss, chemical and ...
Synthesis and characterization of Pt nanocatalyst on Ru0.7Ti0.3O2 support as a cathode for fuel cells application
(Elsevier Science Sa, Lausanne, 2015)
Ruthenium oxide/titanium oxide, with a Ru:Ti atomic ratio of 7:3 was synthesized by modified sol-gel procedure and used as a support for platinum nanocatalyst for oxygen reduction reaction. The synthesized materials were ...
Ultraviolet-B component of sunlight stimulates photosynthesis and flavonoid accumulation in variegated Plectranthus coleoides leaves depending on background light
(Wiley, Hoboken, 2015)
We used variegated Plectranthus coleoides as a model plant with the aim of clarifying whether the effects of realistic ultraviolet-B (UV-B) doses on phenolic metabolism in leaves are mediated by photosynthesis. Plants were ...
Silicon in vascular plants: uptake, transport and its influence on mineral stress under acidic conditions
(Springer, New York, 2015)
So far, considerable advances have been achieved in understanding the mechanisms of Si uptake and transport in vascular plants. This review presents a comprehensive update about this issue, but also provides the new insights ...
The Relationship of Physicochemical Properties to the Antioxidative Activity of Free Amino Acids in Fenton System
(Amer Chemical Soc, Washington, 2015)
Herein we compared antioxidative activities (AA) of 25 free L-amino acids (FAA) against Fenton system-mediated hydroxyl radical (HO center dot) production in aqueous solution, and examined the relation between AA and a set ...
Effects of acute cooling on fish electroretinogram: A comparative study
(Elsevier Science Inc, New York, 2015)
Temperature dependence of electroretinogram (ERG) was investigated in 3 fish species occupying different habitats - dogfish shark (Scyliorhinus canicula), Prussian carp (Carassius gibelio) and European eel (Anguilla ...
The role of autophagy and lipolysis in survival of astrocytes under nutrient deprivation
(Elsevier Ireland Ltd, Clare, 2015)
Astrocytes can survive nutrient deprivation (ND) for days. However, the pro-survival strategy of astrocytes under such a metabolic challenge is still not clear. In the present study, we examined the effects of inhibition ...
Synthesis of Anatase Nanopowders by Sol-gel Method and Influence of Temperatures of Calcination to Their Photocatalitic Properties
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2015)
The titanium dioxide (TiO2) nanopowders were produced by sol-gel technique from tetrabutyl titanate as a precursor, varying the temperature of calcination (from 500 to 550 degrees C with the step of 10 degrees C). XRPD ...
Hydrothermally assisted synthesis of YMnO3
(Elsevier Sci Ltd, Oxford, 2015)
In this work single phase hexagonal YMnO3 powders were prepared starting from Y(CH3COO)(3)center dot xH(2)O, Mn(CH3COO)(2)center dot 4H(2)O, KMnO4 and KOH using methods of conventional (280 degrees C for 6 h) or microwave ...
Correlations between the anatomical traits of gymnocladus canadensis lam. In heartwood and sapwood of early- and latewood zones of growth rings
(Srpsko biološko društvo, Beograd, i dr., 2015)
This paper shows correlations between vessel characteristics and differences in growth-ring width in heartwood and sapwood. Analyzed samples were from an iron-wood tree (Gymnocladus canadensis Lam.) that grew in the ...
