Effects of lanthanum and cerium on the growth and mineral nutrition of corn and mungbean.
BACKGROUND AND AIMS Plant growth responses to the rare earth elements lanthanum (La) and cerium (Ce) have been reported, but little is known about the effects of these two elements on plant mineral nutrition. METHODS Corn (Zea mays 'Hycorn 82') and mungbean (Vigna radiata 'Berken') were grown in continuous flowing nutrient solutions containing 0, 0.2, 1.0 and 5.0 microm La or Ce. At harvest p...
متن کاملon the comparison of keyword and semantic-context methods of learning new vocabulary meaning
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...

15 صفحه اولEffects of cerium and lanthanum on Arabidopsis thaliana
The effects of cerium and lanthanum on the vegetative and reproductive growth of Arabidopsis thaliana were investigated. Addition of cerium (III) nitrate (0.5-50μM) and/or lanthanum nitrate (0.5-50μM) to the culture medium and the potting mix showed varied results. Pot trials were done with uniform conditions for light, water and temperature. Factors examined include root length, height, number...
متن کاملPhase segregation in cerium-lanthanum solid solutions.
Electron energy-loss spectroscopy (EELS) in combination with scanning transmission electron microscopy (STEM) reveals that the La enrichment at the surface of cerium-lanthanum solid solutions is an averaged effect and that segregation occurs in a mixed oxide phase. This separation occurs within a crystalline particle, where the dopant-rich phase is located at the surface of the dopant-deficient...
