(Marcel Dekker Inc, 2003)Data on the short-term effects of fumigation with hydrogen fluoride (HF) on the response behavior of the Nicotiana tabacum L. cv. St. Karabalar 6265 are being presented. Growth rate, fluoride accumulation in leaves and ... -
Lower and upper directional differentiability of the set valued maps and their applications
(Watam Press, 2003)In this paper the lower and upper directional differentiability concepts of the set valued maps are introduced and the directional differentiability properties of the marginal functions are studied. Sufficient condition ... -
Flotation of colemanite from realgar
(Pergamon-Elsevier Science LTD, 2003)Pure colemanite and realgar crystals, collected from Emet Colemanite deposit in Kutahya, Turkey, were used to determine the adsorption mechanisms of flotation reagents on mineral surfaces. The floatability of pure minerals ... -
Comparison of generalized approximate cruise range solutions for turbojet/fan aircraft
(Amer Inst Aeronaut Astronaut, 2003)Two different approximate solutions are proposed and compared with the numerical solution of the constant-altitude-constant-Mach-number cruise range for turbojet/fan aircraft. The approximate solutions consider both cambered ... -
Essential oils of some Boswellia spp., myrrh and opopanax
(Wiley, 2003)The essential oils obtained by hydrodistillation of resins of Boswellia neglecta, B. pirottae,B. rivae, Commiphora myrrha (myrrh) and C. guidottii (opopanax or scented myrrh) were analysed using GC-MS. alpha-Thujene (19.2%), ... -
Thermal shock parameters [R, R ''' and R ''''] of magnesia-spinel composites
(Elsevier Sci LTD, 2003)Thermal shock parameters (R, R'" and R"") have been calculated using measured strength and modulus values for model magnesia-spinel composite materials. The R'" and R"" parameters vary with both spinel content (0-30%) and ... -
Effectiveness of peer delivered simultaneous prompting on teaching community signs to students with developmental disabilities
(Council Exceptional Children, 2003)A multiple probe study across behaviors, replicated across participants, assessed effectiveness of peer delivered simultaneous prompting (SP) in teaching expressively identifying community signs to four students with ... -
Hydrothermal synthesis of lead titanate and lead zirconate titanate electroceramic particles
(Taylor & Francis LTD, 2003)Hydrothermal synthesis of two lead-based perovskite powder systems, lead titanate and lead zirconate titanate, was investigated. Phase-pure perovskite lead titanate and lead zirconate titanate with various morphologies ... -
Formation mechanisms and morphological changes during the hydrothermal synthesis of BaTiO3 particles from a chemically modified, amorphous titanium (hydrous) oxide precursor
(Elsevier Sci LTD, 2003)The formation mechanism of BaTiO3 under hydrothermal conditions was investigated. A coprecipitated precursor prepared from chemically modified titanium isopropoxide with acetylacetone and barium acetate was used as a ... -
The effect of different nucleation temperatures on the grain morphology of alpha-SiAlON ceramics
(Trans Tech Publications LTD, 2003)Nitrogen rich yttrium-cerium containing multi-cation alpha-SiAlON starting compositions were prepared by gas pressure sintering using conventional alpha-Si3N4 powder. Microstructural characterization of the two stage ... -
Synthesis of an iron-chromium ceramic pigment by using limonite and chromite mixtures
(Belgian Ceramic Society, 2003)The pigments, which are important parts of ceramic industry, have been produced by a prolonged expensive process due to a necessity of using very expensive pure oxides. Therefore, it is important to produce pigments from ... -
Dual quaternionic reformulation of electromagnetism
(Slovak Acad Sciences Inst Physics, 2003)It can be said that Maxwell's equations are one of the well-known equations of Physics. Despite the fact that this equations are more than hundred years old (1865), they still are the cornerstone of electrodynamics. Although ... -
Intentional communicative behaviours of Turkish-speaking children with normal and delayed language development
(Blackwell Publishing LTD, 2003)Background Language profiles may predict whether children with slower language development will catch up to their peers by overcoming this transient phenomenon or will be at risk for persistent language disorders. The ... -
