Grass was field-dried to 3 different dry matter (DM) levels (200, 430 and 540 g/kg) and inoculated with 10(6)-10(7) cfu/g of a Listeria monocytogenes strain sharing a phagovar occasionally involved in foodborne outbreaks of listeriosis. Formic acid (3 ml/kg) or lactic acid bacteria (8 x 10(5)/g) with cellulolytic enzymes were applied only to forages with low and intermediate DM levels. Forages ...

Forage conservation permits a better supply of quality feed when forage production is low. While haymaking and ensiling have been practiced for generations, research is still needed to 1) understand the processes affecting quality during harvesting and storage and 2) develop practical means to minimize losses and enhance quality. Several trends in harvesting forages for silage are notable. Kern...

We investigate, at a laboratory scale, the collapse of cylindrical shells of radius R and thickness t induced by a granular discharge. We measure the critical filling height for which the structure fails upon discharge. We observe that the silos sustain filling heights significantly above an estimation obtained by coupling standard shell-buckling and granular stress distribution theories. Two e...

Abstract: Processing consists of sequential operations aimed at cleaning, classifying, and treating seeds, with the goal improving quality lot. The aim this study was to evaluate effect processing stages on physical physiological chickpea cultivar BRS Cícero. Seeds were sampled before after passing through air screen machine (upper sieve 12 mm lower 7.5 mm), elevators, storage silo, gravity tab...

Designing systems in a service-oriented manner, in which application features are decoupled and run as independently executing services over a network, is becoming more commonplace and popular. Service-oriented programming provides a natural way to model and manage many types of systems and allows software development teams to achieve operational flexibility, scalability, and reliability in a c...

This essay challenges fundamental, silo-oriented assumptions about the IS discipline. It shows how work system theory and its extensions form a potential basis for overcoming that silo-orientation and finding and exploiting areas of overlap with other disciplines. Within the IS discipline, this paper shows how WST and extensions provide a basis for thinking differently about fundamental topics ...
