CONTEXT Anthropogenic vectors enhance the natural dispersal capacity of plant seeds significantly in terms of quantity and distance. Human-mediated seed dispersal (i.e. anthropochory) greatly increases the dispersal of crop species across agroecosystems. In the case of oilseed rape (OSR), spillage of seeds from grain trailers during harvest has never been quantified. METHODS Our experimental ...

Probe traps are sensitive tools for detecting populations of beetles in stored grain, but their use for estimating insect density in concrete silos has not been established. Populations of grain beetles infestingwheat in concrete silos at twocommercial storage facilities innorth centralOklahoma were sampled using probe traps and grain probe samples over a 17-wk period. Grain temperature and qua...

We show that if a polynomial filled Julia set has empty interior, then it is computable.

Our measurements show that liquid permeability of foam-filled granular packings is fully controlled by the microstructure foam. The main parameter bubble-to-grain size ratio, increase which leads to a very sharp decrease permeability. saturation also contributes choice made for surfactant shown be important.

five improved along with three local rice varieties were crossed in a line× tester method in 2001. fifteen f1 hybrids and eight parental genotypes were planted in a randomized complete block design with 3 replications at rice research institute of iran, rasht, in 2002. the main objective of the research was to estimate the general and specific combining ability and gene action for 10 agrnomic a...

We present in this paper a new strategy of handwriting or hand drawing velocity modeling Based on the Beta theory. The introduced approach aims to improve the interpretability of the dynamic profile model, reduce the data redundancy, and ameliorate the features accuracy. Indeed, we showed that the curvilinear velocity of handwritten or hand drawn trajectory can be rebuilt by superposing two com...
