Effects of substrates and temperatures on Cynara cardunculus L. seed germination
(Romanian Agricultural Research, 2011)
The aim of this study was to determine the effects of substrates and temperatures on Cynara cardunculus seed germination. The tests encompassed the following substrates - filter paper, sand and compost. The follow-ing ...
Dehydration investigations of a refractory concrete using DTA method
(Springer, Dordrecht, 2012)
The base mix refractory concrete is corundum-based, containing corundum as refractory aggregate and CAC as hydraulic binder, with a spinel as an additive. The authors investigated the dehydration reactions which occur from ...
Integrated use of different fish related parameters to assess the status of water bodies
(University of Ljubljana - Veterinary Faculty, 2015)
Freshwater bodies receive high levels of different toxicants. Since fish are typically situated at the top of aquatic food chains, they have a good potential to be used as indicators of water pollution. Assessment of the ...
Temperature effects on common cocklebur (xanthium strumarium l.) Seed germination
(Natl Agricultural Research & Development Inst, Fundulea, 2012)
A better understanding of the seed ecology can be helpful for prediction of the potential of weed species to spread, for prediction of their invasiveness, and for development of more effective weed management strategies. ...
Grassland vegetation of the Molinio-Arrhenatheretea class in the NW Balkan Peninsula
(Wiley, Hoboken, 2014)
Questions: How does the floristic composition of plant species of meadows and mesic pastures vary along a broad geographical gradient in the NW Balkans? How does the current phytosociological classification of the ...
Zirconium dioxide nanopowders with incorporated Si4+ ions as efficient photocatalyst for degradation of trichlorophenol using simulated solar light.
(Elsevier Science Bv, Amsterdam, 2016)
We present a hydrothermal method for synthesis of zirconia nanopowders: pure and with incorporated Si4+ ions. Zirconyl chloride and tetraethyl orthosilicate were used as precursors. As prepared powders were annealed at 600 ...
A modified method for assessment of the morphological stage of development as a predictor of alfalfa herbage chemical composition and nutritive value
(Cambridge Univ Press, New York, 2013)
The aim of the current work was to investigate the possibility of modifying the existing mean stage by weight (MSW) system for evaluating the average development stage in alfalfa. The modification was performed with the ...
The effect of annealing temperature and time on synthesis of graphene thin films by rapid thermal annealing
(Elsevier Science Sa, Lausanne, 2015)
In this paper, we performed synthesis of graphene thin films by rapid thermal annealing (RTA) of thin nickel copper (Ni/Cu) layers deposited on spectroscopic graphite as a carbon source. Furthermore, we investigated the ...
Weeds shift from generalist to specialist: narrowing of ecological niches along a north-south gradient
(Czech Botanical Soc, Praha 2, 2014)
There are changes in the realized niches of species along environmental gradients, especially at the edge of their distribution where they become more specialized. A classical case is weeds of the Caucalidion alliance that ...
Interpretation of hybrid x sowing date interaction for oil content and oil yield in sunflower
(Elsevier, Amsterdam, 2012)
Due to the presence of an interaction, it is often difficult to recommend which sunflower hybrids should be planted based on specific sowing dates or production regions. Through this study, the hybrid x sowing date (H x ...
