Experimental data from batch vessels on cumulative volumetric drop-size distributions at various times are shown to yield useful information on probabilities of droplet-breakup as a function of drop-size. Such information is sufficient for a priori prediction of drop-sizes in agitated dispersions in batch and continuous vessels. It may also be useful in predicting heat and/or mass transfer in l...

C an a machine think ? Can a ma­ chine have conscious thoughts in exactly the same sense that you and I have? If by "machine" one means a physical system capable of performing certain functions (and what else can one mean?), then hu­ mans are machines of a special biolog­ ical kind, and humans can think, and so of course machines can think. And, for all we know, it might be possible to produce ...

Breakage occurs in several particulate systems that are simulated using the discrete element method (DEM), namely crushing and grinding as well inadvertently others include transportation, handling, mixing, separation geotechnical applications. Different approaches may be used to describe particle breakage DEM, but cases which influences significantly flow behaviour of material, imbedding descr...

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 ...

the aim of this study was to evaluate the efficacy of a computer - based training program of attention, memory and executive functions in enhancing neuropsychological performances as well as functional outcome in clients with schizophrenia.a total of 15 clinically stable out patients with diagnostic and statistical manual of mental disorders (dsm-iv-tr) criteria for schizophrenia, diagnosed wit...

Abstract This paper concerns the tool wear in hard turning of AISI 52100 hardened steel by means PCBN tools. The purposes this work are development a model and its implementation FEM-based procedure for predicting crater flank progression during machining operations studying influence on process terms geometry modifications stress variation tool. developed model, able to update worn as function...

Particle breakage was reported to have great influence on the mechanical property of granular materials. However, limited studies were conducted quantify detailed effects relative density and initial grading particle behaviour materials under different confining pressures. In this study, a series monotonic drained triaxial tests performed isotropically consolidated with four gradings densities....

Oncogene-induced DNA replication stress activates the DNA damage response (DDR), a crucial anticancer barrier. DDR inactivation in these conditions promotes genome instability and tumor progression, but the underlying molecular mechanisms are elusive. We found that overexpression of both Cyclin E and Cdc25A rapidly slowed down replication forks and induced fork reversal, suggestive of increased...
