This paper attempts to determine the mechanisms governing the grain growth process that occurs during lamination annealing of a cold-rolled, motor-lamination steel. A new simulation approach linking a Monte Carlo model, with EBSD scans used as input, has been employed to incorporate the effects of crystallographic texture on the simulated grain growth process. The results from the texture analy...

Barley (Hordeum vulgare) and wheat (Triticum aestivum) are often stored dry with 14% or less moisture, which during rainy periods may require that grains are dried after harvest. The hypothesis is that air-tight storage of high-moisture barley and wheat will increase nutrient digestibility due to chemical conversions prior to feeding. The objective was to evaluate the effect of high moisture co...

Microbial symbionts of insects provide a range of ecological traits to their hosts that are beneficial in the context of biotic interactions. However, little is known about insect symbiont-mediated adaptation to the abiotic environment, for example, temperature and humidity. Here, we report on an ancient clade of intracellular, bacteriome-located Bacteroidetes symbionts that are associated with...

Abnormal grain growth was studied in an Fe-1%Si alloy using automated Electron Backscattered Diffraction (EBSD). Industrially processed samples were temper rolled to reductions of 0%, 1.5% and 8% and then annealed in a range of atmospheres for various times followed by quenching in water. Abnormal grain growth was observed regardless of atmosphere although a moist hydrogen-nitrogen mixture resu...

Campabadal, Carlos A. Ph. D., Purdue University, December 2013. Ozonation Systems as a Non-Chemical Alternative for Stored Grain Protection. Major Professors: Dirk E. Maier and Richard L. Stroshine. The use of ozone as a non-chemical alternative in stored grain protection was studied by conducting scale-up demonstrations using a fixed bed ozonation system and developing a semi-continuous counte...

Five monoterpenes naturally occurring in essential oils were tested for their insecticidal and repellent activities against the bruchid beetle Callosobruchus maculatus and the maize weevil Sitophilus zeamais. The monoterpenes were highly efficient as inducers of mortality or repellency against both insect species. They were more efficient in their fumigant activity against C. maculatus than aga...

This chapter provides an overview of insect trapping and interpretation of trap captures for stored-product protection in bulk grain, food processing, and retail environments. The use of traps for detection, monitoring, and population estimation requires considerable knowledge of insect biology and appropriate trap use. Trap use is essential for development of meaningful integrated pest managem...
