in order to determine the best planting date and seeding rate of two triticale genotype in mashhad climate condition on 2007-2009 growing season, an experiment was carried out, using a split-plot design based on randomized complete block design with three replication, at torogh agricultural research station, mashhad, iran. main plots devoted to five seeding dates and factorial combination of th...

an experiment was conducted in bandar kyashahr research field in 2002 to evaluate the effects of plant density and planting pattern on weed populations and yield of peanut (arachis hypogaea l.). the experiment was of a randomized complete block design with three replications. a factorial trial with two factors of planting pattern (square and rectangular arrangements) and plant density (3, 5.3, ...

This dissertation investigates the main research question: Which classification of innovation explains the heterogeneous timing of revenue realization? Given the significance of financial gain, researchers are recommended to pay attention to whether innovation outcomes result in commercial gains in the short term. Following this notion, a new category of innovation, planting and harvesting, is ...

Infrared spectra of the mass selected ionic complexes H2–HCO 1 and D2–DCO 1 have been recorded in the vicinity of their n1 vibrations ~H2 /D2 stretch! by means of photofragmentation spectroscopy. The anomalous rotational constants obtained by fitting the observed line positions to a semirigid Watson A-type Hamiltonian reflect the appreciable zero-point excursions of the H2 /D2 molecule. Barrier...

In the senescence-accelerated mouse of the P8 line (SAMP8), age-related changes in circadian timing include a decrease in amplitude of the rhythm, a slower rate of re-entrainment following a phase advance, and a longer free-running period ( ). The present study extends previous research by investigating possible split activity rhythms in the SAMP8. Running wheel activity was examined in 2-, 7-,...

ÐConsider a ceramic in an environment, corroding gradually by a surface reaction. When in addition subject to a mechanical load, the ceramic loses mass preferentially at grain-boundary grooves where stress concentrates, so that atomistically sharp cracks may nucleate. Before becoming a crack, a groove maintains local equilibrium at its root; after, it loses local equilibrium. The crack further ...

The influence of the vesicular-arbuscular mycorrhizal fungus Glomus intraradices (Gi) and superphosphate (P) on penetration, development, and reproduction of Meloidogyne incognita (Mi) was studied on the Mi-susceptible cotton cultivar Stoneville 213 in an environmental chamber at 28 C. Plants were inoculated with Mi eggs at planting or after 28 days and destructively sampled 7, 14, 21, and 28 d...
