Abstract Background A pot experiment was conducted to evaluate the phytotoxic thresholds of zinc oxide (ZnO NPs), iron (FeO copper (Cu and silver nanoparticles (Ag NPs) on cotton. All were biosynthesized from Conocarpus erectus L. leaf extract. They characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), Fourier transmission infrared spectroscopy (FTIR). Five concentration...

It has been shown that the adverse effects of salinity can vary between different varieties same plant species. This study was conducted to determine tolerability three newly released lines maize saline conditions when primed with ethylene diamine tetraacetic acid (EDTA) and salicylic (SA) each at 1.0 M concentration; seeds distilled water were used as control. Concentrations 0, 50, 100, 150 30...

Soil salinity is a big threat to the world and has become major concern agricultural productivity. Sweet pepper (Capsicum annuum L.) high value vegetable; due its quality nutrition. Despite growing all over country, production not so in Bangladesh. As popular crop also available everywhere, some varieties of sweet were put under this study assess their salt tolerance level. A pot experiment was...

Previous studies have proved that partial information transmission can be found between intensity and pitch. In our last study, it was demonstrated that the timbre attribute can be transmitted as partial information between timbre and intensity. We manipulated the two attributes of stimulus, namely, timbre (piano vs. violin) and pitch (high vs. low), to find out whether they also have partial i...

In many everyday situations, we bias our perception from the top down, based on a task or an agenda. Frequently, this entails shifting attention to a specific attribute of a particular object or scene. To explore the cost of shifting top-down attention to a different stimulus attribute, we adopt the task-set switching paradigm, in which switch trials are contrasted with repeat trials in mixed-t...
