PURPOSE To model intrachromosomal clustering of DSB (DNA double strand breaks) induced by ionizing radiation. That DSB are located non-randomly along chromosomes after high LET irradiation, with clustering even at extremely large scales, has been confirmed by recent pulsed field gel electrophoresis data for size distributions of DNA fragments. We therefore extend the standard random-breakage mo...

european corn borer, ostrinia nubilalis hb. is a polyphagous insect, recognizing world widely as the predominant pest of maize. in this research the relative resistance of eleven hybrids of maize was evaluated in a field in agricultural and natural resources research center of moghan. this experiment was conducted in three replicates in a complete randomized block design. for comparison of the ...

Abstract There is a need of reducing the uncertainty in traffic loading-induced settlements within railway embankments. A previously developed model for unbound stone-based materials has been implemented modelling rockfill Particles were represented by simple breakable tetrahedral clumps spheres with four asperities each. Both corner breakage and particle splitting allowed. Embankments heights ...

A method based on the reverse breakage matrix approach is proposed for controlling effects that milling has particle size distribution and composition of comminuted material. Applicability, possibilities, limitations are tested examples related to process wheat flour milling. It been shown can be successfully used defining input material leading desired, predetermined compositional in output Mo...

Particle fracture, the formation of small particles as result breakage large ones, and aggregation, combination have important implications in industry (e.g. food processing, pharmaceutical production) geophysics (e.g., snow avalanches rock debris flows). Also, presence different size that from fracture aggregation can induce segregation, resulting migration to regions flow. Here, we formulate ...

As one of the commonly-used solid dosage forms, pharmaceutical tablets have been widely used to deliver active drugs into the human body, satisfying patient's therapeutic requirements. To manufacture tablets of good quality, diluent powders are generally used in formulation development to increase the bulk of formulations and to bind other inactive ingredients with the active pharmaceutical ing...

There is often obvious particle breakage for silica sand under high-stress, which will lead to the bearing capacity reduction and excessive settlement of foundation. This paper focuses on characteristics marine from East China Sea high-stress conditions. A series conventional triaxial tests sand, including consolidated drained (CD) undrained (CU) shear tests, were conducted confining pressures ...
