INTRODUCTION Endocrine pancreatic segregation is regulated by the autonomic nervous system. The parasympathetic system stimulates insulin production by the beta cells and inhibits the adrenergic discharge by the sympathetic nervous system. The aim of this study was to evaluate the effect of percutaneous neurostimulation (PENS) of dermatome T7, generating a somato-autonomic reflex, whose efferen...

One hundred and seven fattening pig units randomly selected in Catalonia (Spain) were surveyed during 2001-2003, in order to determine the frequency of the prophylactic use of antimicrobials and mass treatments against respiratory and enteric disease outbreaks. Logistic regression and regression tree analysis were done to determine the factors associated with the on-farm mass antimicrobial usag...

Massfinishing is amongst themost widely usedfinishing processes inmodernmanufacturing, in applications fromdeburring to edge radiusing and polishing. Processing objectives are varied, ranging from the cosmetic to the functionally critical. One such critical application is the hydraulically smooth polishing of aero engine component gas-washed surfaces. In this, andmany other applications the dri...

Abstract Additive manufacturing is a vanguard production technology that has contributed greatly to speed up replacing on the market of complex-shaped components. A delicate and unavoidable phase additive relating post-processing components, especially finishing process. Post-processing needs be automated made scalable so can actually adopted also for mass production. In this respect, an emergi...

Aluminium is used extensively in the transportation, architecture, electronic and packaging industries. Aluminium presents particular characteristics such as low density, high ductility and a highly protective natural oxide film. However, formability, corrosion resistance, weldability, adhesion and surface aspect depend on the chemistry and microstructure of the metal surface. Properties of par...

This work deals with the optimization of crucial process parameters related to abrasive flow machining applications at micro/nano-levels. The optimal combination for nano-finishing has been determined by applying a modified virus-evolutionary genetic algorithm. algorithm implements two populations: One comprising hosts and one viruses. Viruses act as information carriers thus they contribute bo...
