Evaluation of Resistance to Low Temperatures in Promising Interspecies Grapevine Hybrids
(Acta Horticulturae, 2009)
Frost resistance has been tested in 14 interspecific hybrids already selected for table grape production. The experiment was carried out by artificial exposure to low temperature of cuttings. This test was repeated three ...
Light transmission through fiber post: The effect on adhesion, elastic modulus and hardness of dual-cure resin cement
(Elsevier Sci Ltd, Oxford, 2009)
Objectives. The aim of this study was to investigate the effect of fiber post light transmitting ability to the continuity of resin cement-root dentin (C-RD) and resin cement-fiber post (C-FP) interface, elastic modulus ...
Isoenzyme Polymorphism in Apricot Cultivars
(Amer Pomological Soc, University Pk, 2009)
Eighteen enzyme systems were studied in 50 apricot (Prunus armeniaca L.) cultivars of diverse geographical origin using polyacrylamide gel electrophoresis. Thirteen systems were polymorphic at 20 loci. This polymorphism ...
Structure and thermal behavior of the layered zincophosphate [NH3-CH2-CH(NH3)-CH3](ZnPO4)(2)
(Elsevier Science Sa, Lausanne, 2009)
A zinc phosphate with the composition [NH3-CH2-CH(NH3)-CH3](ZnPO4)(2), containing the doubly protonated 1,2-diaminopropane (abbr. HDAP), was synthesized by hydrothermal crystallization of zinc nitrate, phosphoric acid, ...
Strawberry Production in Serbia - the State and Perspectives
(Acta Horticulturae, 2009)
This paper presents the state of strawberry production in Serbia and its perspectives. The annual strawberry production ranges from 30,000 to 35,000 t. Such production is realized on 5,000 ha with average yields of 3.7-5.5 ...
Influence of yb2o3 and er2o3 on batio3 ceramics microstructure and corresponding electrical properties
(Amer Ceramic Soc, Westerville, 2009)
In this article the additives Yb and Er oxides are used as doping materials for BaTiO3-based multilayer devices. The amphoteric behavior of these rare-earth ions leads to the increase of dielectric permittivity and decrease ...
Assessment of the water quality of aquatic resources using biological methods
(Desalination Publ, Hopkinton, 2009)
Assessment of water quality at Radmilovac estate near Belgrade that is used for irrigation of cultures and as a water supply for experimental fish farm and hatchery was performed by using aquatic invertebrates (zooplankton ...
Possibilities of using fruit processing residues as a fuel
(Agronomski fakultet Sveucilista u Zagrebu, 10000 Zagreb, 2009)
Energy demand in the world and limited sources of fossil fuels impose larger amounts of renewable energies. Agriculture production can be very important factor as a renewable energy producer concerning large amounts of ...
Copper(II) complexes of N-heteroaromatic hydrazones: Synthesis, X-ray structure, magnetic behavior, and antibacterial activity
(Elsevier Science Sa, Lausanne, 2009)
Three novel copper(II) complexes as condensation derivatives of 2-pyridinecarboxaldehyde, 2-acetylpyridine or 2-quinolinecarboxaldehyde with ethyl hydrazinoacetate hydrochloride were synthesized. X-ray crystal structures ...
Effect of different fermentation parameters on bioethanol production from corn meal hydrolyzates by free and immobilized cells of Saccharomyces cerevisiae var. ellipsoideus
(Wiley, Hoboken, 2009)
BACKGROUND: Bioethanol produced from renewable biomass, such as corn meal, is a biofuel that is both renewable and environmentally friendly. Significant scientific and technological investments will be needed to achieve ...
