Morphological control of multimetallic nanostructures is crucial for obtaining shape-dependent physical and chemical properties. Up to date, control of the shapes of multimetallic nanostructures has remained largely empirical. Multimetallic nanostructures have been produced mostly through seed-mediated growth. Understanding the role played by starting nanocrystal seeds can help in controlling t...

Past research indicates that whitebark pine seeds are a critical food source for Threatened grizzly bears (Ursus arctos) in the Greater Yellowstone Ecosystem (GYE). In recent decades, whitebark pine forests have declined markedly due to pine beetle infestation, invasive blister rust, and landscape-level fires. To date, no study has reliably estimated the contribution of whitebark pine seeds to ...

It is generally accepted that larger seeds give rise to seedlings with better performance. On the other hand, the size that a seed reaches is genetically determined by at least two different traits ; the genetic variability of the developing embryo and the genetic variability of the maternal plant. Thus, the relative contributions of these two traits affect seedling performance by influencing s...

ARIEGATED seedcoat color was originally discovered in the variety Supreme (CI-8O26) which is reported to be a selection from Red Bobs (CI-6255) of hexaploid wheat, Triticum aestiuum L. The trait is characterized by a red and white variegated seedcoat and varying proportions of completely white-seeded tillers on plants with otherwise red o r variegated seeds, or red, white and variegated seeds a...

this study was aimed at evaluating the effects of planting’s different dates on the trend of leaf area index, dry biomass weight and panicle weight in addition to the yield of rice varieties for one year in the north region of khuzestan, as spilt plots in the form of fully random blocks in three repetitions. main factor was the date of planting at three levels (26 may, 10 jun, 26 jun) and the s...

INTRODUCTION History Tamarind is a leguminous trees of genus Tamarindus a monotype taxon with only specie indicum. Tamarindus is medieval latinization of the Arabic name for the fruit, meaning Indian date. The fruits of the tamarind were traded widely in ancient times. Records from the eastern Mediterranean show Tamarindus indica was already in cultivation there in the fourth century B.C. On en...

Introduced plant success often is attributed to release from natural enemies in their new ranges. However, herbivores may accumulate over time and reduce invasiveness but evidence for this process to date is weak. We report here that enemy release is indeed limited to the early stages of introduction of the Chinese tallow tree (Sapium sebiferum). In bioassays and gardens along a geographical gr...

The first convincing detection of planets orbiting stars other than the Sun, or exoplanets, was made in 1995. In only 20 years, the number of the exoplanets including promising candidates has already accumulated to more than 5000. Most of the exoplanets discovered so far are detected by indirect methods because the direct imaging of exoplanets needs to overcome the extreme contrast between the ...
