VUV single photon gaseous photomultiplier with position capability

A new position sensitive gas photomultiplier for the Vacuum Ultraviolet (VUV) region is presented in this work. The detector is composed by two THGEMs, followed by a 2D-THCOBRA being operated in Ne/CH4(5%), at 1 bar pressure in single photon mode. The 2D-THCOBRA is an hybrid microstructure which combines the robustness and the resistance to discharges of a THGEM with the two independent charge multiplication st...

Implementação de um ERP na indústria vitivinícola

Num mercado global cada vez mais competitivo, torna-se essencial que as empresas se tornem mais flexíveis e competitivas. A aposta em sistemas que permitam uma correta gestão da informação pode fazer a diferença entre continuar ou não a fazer parte do mercado. Os Sistemas de Informação aparecem para colmatar esta necessidade das empresas de gerir eficazmente a informação. O principal objetivo deste trabalho é d...

When sociable workers pay off: Can firms internalize social capital externalities?

We use an endogenous growth model to contrast the socially optimal allocation of human capital with the decentralized solution, in a context where workers make the choices that determine social capital accumulation. As social capital is expected to increase productivity but is not traded in markets, a positive social capital externality is identified. We discuss the possibility that, in response to this externa...

Evaluation of fecal recovering and long term bias of internal and external mark...

The objective of this work was to estimate the total recovering and the long term bias of the estimates of fecal excretion using the external markers chromic oxide and titanium dioxide and internal markers indigestible dry matter (iDM), indigestible neutral detergent fiber (iNDF) and indigestible acid detergent fiber (iADF) in a digestion assay with cattle fed different diets. Fourteen F1 Red Angus x Nellore av...

In situ estimation of indigestible compounds contents in cattle feed and feces ...

The objective of this experiment was to evaluate estimates of concentration of indigestible dry matter (iDM), indigestible neutral detergent fiber (iNDF) and indigestible acid detergent fiber (iADF) in samples of cattle feed and feces processed at different particle sizes (1-, 2-, and 3-mm) using bags made from nylon (50 μm), F57 (Ankom®), and non-woven textile (NWT - 100 g/m²) in a in situ evaluation proc...

The objective of this work was to evaluate the fecal excretion profile and the short term bias of the external markers chromic oxide and titanium dioxide and the internal markers indigestible dry matter (iDM), indigestible neutral detergent fiber (iNDF) and indigestible acid detergent fiber (iADF) in a digestion trial with cattle fed different diets. Fourteen F1 Red Angus × Nellore bulls averaging 12 months old...
