This paper shows that for microbial communities, "fences make good neighbors." Communities of soil microorganisms perform critical functions: controlling climate, enhancing crop production, and remediation of environmental contamination. Microbial communities in the oral cavity and the gut are of high biomedical interest. Understanding and harnessing the function of these communities is difficu...

The study investigated the effects of prolonged oral administration of dexamethasone at a low daily dosage of 0.75 mg/head per day (Dexa) on beef cattle productive traits, behaviour and meat quality. In all, 14 finishing Marchigiana bulls were used in a trial that begun 56 days prior to slaughter, of which six bulls received treatment from day 5 to day 53, whereas the remaining animals were use...

Once a new product is available, if the company starts the sales without building an initial inventory (myopic policy), the demand for the product grows rapidly due to extensive word of mouth spreading from past sales and soon may exceed the firm’s capacity resulting in lost sales. To avoid this problem, companies generally delay product launch to build sufficient inventory prior to starting sa...

Modeling and performance evaluation of current production systems gains more and more importance because of growing system complexity and production costs. Therefore tools and methods are needed that allow a simple modeling and performance evaluation of systems. The goal of this paper is to give a short introduction into the speci cation of production systems using the model description languag...

Prednisolone is a synthetic corticosteroid acting on both hydrosaline balance and metabolism that is liable to fraudulent administration to meat-producing animals for growth-promoting purposes. Its use outside strict therapeutic control and prescription is banned by the European legislation, but official controls are hampered by its negligible direct excretion into the urinary matrix. Recent st...

F beef cattle management practices are more cost effective or have a higher return on investment than properly used growth promoting implants. Growth promoting implants are pellets that are implanted under the skin of the ear of growing calves. These pellets release extremely low concentrations of various hormones, which improve average daily gain 7 to 17 percent and feed efficiency 4 to 12 per...

The paper examines how the use of mobile technologies such as tablets and handheld MP3 players can support and promote oral language production among young language learners. It explores how the use of these mobile technologies in the language classroom supports pedagogical practices anchored in socioconstructivist theories of SLA that emphasize the role of dialogue and social interaction among...

The immune responses (serum anti-porcine epidemic diarrhea virus [PEDV] immunoglobulin G [IgG] and milk antiviral neutralizing antibodies) induced by various combinations of two PEDV immunization modalities (vaccine and oral immunization) were examined in unrelated swine production units in different locations. Anti-PEDV antibodies were undetectable in serum and milk of the control group (non-v...

This paper presents some issues in interarticulator programming in speech production, using as an example the production of a vowel, a bilabial stop consonant, and a vowel. The mechanism for making the labial closure is presented as well as the control of the duration of the closure. An examination of the coordination of the tongue movement from the first to the second vowel with the lip moveme...

Tissue-engineered oral mucosal equivalents have been developed for clinical applications and also for in vitro studies of biocompatibility, mucosal irritation, disease, and other basic oral biology phenomena. This paper reviews different tissue-engineering strategies used for the production of human oral mucosal equivalents, their relative advantages and drawbacks, and their applications. Techn...
