Ozonation Systems as a Non-Chemical Alternative for Stored Grain Protection
… 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 counterflow and a continuous flow ozonation treatment system. The objectives of this research were to …

Numerical model for analysis and control of the quality of bulk-stored grain using cold air
Food grains that have been cooled can be stored for prolonged periods. This is because the rate population increase of insect pests can be slowed, seed viability is maintained, dry matter loss is reduced and the persistence of chemical pesticides can be improved. This thesis reports the development …

Discrete element method simulation of wheat bulk density
… container used for storage or transportation. Stored grain bulk density is higher than the standard bushel test weight because of the overburden pressure and handling practices. The material and equipment properties, and widely varying interactions between kernels add to the complexity of …

Modelling the microclimate in a conical bottomed circular grain silo
… predicting the behaviour of microclimate in the stored grain silo is presented. This analysis is implemented by calculating the air pressure field within an aerated conical bottomed circular silo, to continuing prediction the velocity field. The obtaining results are used to compute the …

Three essays in experimental and behavioral economics of technology adoption in India
… end. We use two rounds of an auction of improved grain storage technology where access to the technology is driven by random prices drawn at the household level. This approach lets us disentangle the price paid from the initial willingness to pay of the recipient, thus allowing us to contrast the …

A Descriptive Study of Grain Production, Consumption, and Storage in Virginia
… respectively, in 2012. One of the products, grain, serves as an important input for raising livestock and poultry. Virginia needs to import grain from other states (Eastern Corn Belt states) to meet current livestock feed requirements, an expense that raises the cost of production over …

Insights into the seasonal ecology and thermal biology of the lesser grain borer, Rhyzopertha dominica (Coleoptera: Bostrichidae)
… the world’s diet. After harvest, these crops are stored for extended periods, but roughly 10 percent of global grain is lost to insect damage, costing the U.S. alone over 2.5 billion dollars annually. Among the estimated 1,500 insect species that can infest stored grain, the lesser grain borer, …

Low-Cost Grain Bin Moisture Sensor Using Multiple Capacitive Elements
The ability to know the condition of grain stored on the farm is very important. Grains grown in the prairie provinces of Canada are valuable commodities and the farm has become a primary storage location for more and more grain as farming operations have been getting larger and larger. With …

Pheromone communication and host-finding behaviour of Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae)
The lesser grain borer, Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae) is a destructive pest of stored grain. Males produce a pheromone, with two components Dominicalure-1 (D 1) and Dominicalure-2 (D2), which is attractive to both sexes. However, little is known about the pheromone biology of …

Grain storage facilities maintenance challenges in Zambia: a case study of the food reserve agency.
… It has been observed that a large proportion of stored grain is wasted because of poor post-harvest management in Southern African countries such as Zambia. Among the factors responsible for losses are inadequate and ineffective grain storage facilities and poor handling practices. In Zambia, the …

Impact of low-temperature storage on quality of high-moisture corn grain
… harvesting of corn can increase the yields of grain and stover and reduce the lignin content of the stover and as a result, can reduce the major costs of feedstock and stover pretreatment in traditional and advanced bioethanol production. Motivated by these advantages, frozen storage is an …

Resistência fisiológica e comportamental de populações de Sitophilus zeamais à permetrina, esfenvalerato e esfenvalerato + fenitrotiona
O caruncho do milho, Sitophilus zeamais Motschulsky, 1855 (Coleoptera: Curculionidae) é considerado a principal praga do milho armazenado no Brasil, sendo o seu controle realizado principalmente por inseticidas. A utilização maciça e intensa destes compostos pode levar à seleção de populações …
