Interactions of Mutiple Biological Fields in Stored Grain Ecosystems

Stored Grain - Mycotoxins

Mycotoxins are toxic fungal metabolites that cause intoxication when consumed by animals, including humans. Fungi that produce mycotoxins are called toxigenic fungi. The toxigenic fungi do not produce mycotoxins after they have been ingested by animals and humans. Toxigenic fungi grow in corn, cereals, soybeans, sorghum, peanuts, silage and other food, feed crops or hay in the field, and in gra...

Competition among Species of Stored-Product Psocids (Psocoptera) in Stored Grain

We evaluated the competition among stored-product psocid species by conducting two series of laboratory experiments. In the first series, three species of Liposcelididae were used: Liposcelis bostrychophila, Liposcelis decolor, and Liposcelis paeta. Five adult females of these species were placed in vials containing wheat, either alone or in all possible combinations of two species. The number ...

STORED ENERGY DRIVEN ABNORMAL GRAIN GROWTH IN Fe

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...

Biological monitoring of aquatic ecosystems in Italy

In Italy, Ecotoxicology has found a place with the Legislative Decree n. 152 (May 11, 1999), emanated in fulfilment of the Directives 91/271/CEE "urban waste-water treatment" and 91/676/CEE "protection of waters against pollution caused by nitrates from agricultural sources". This decree in reality goes beyond (actually anticipating the content of the Framework Directive on Water, still under w...
