Information and Communication Technology (ICTs) is growing rapidly due to human needs for communication and fast access to information. This brought a new awareness around the world to create good governance and clean government. This is known as public management reform, called e-Government (e-Gov). Interoperability is a key issue in implementing an e-Government system. Grid-based services for...

in this paper, we introduce the new notion of strongly j-clean rings associatedwith polynomial identity g(x) = 0, as a generalization of strongly j-clean rings. we denotestrongly j-clean rings associated with polynomial identity g(x) = 0 by strongly g(x)-j-cleanrings. next, we investigate some properties of strongly g(x)-j-clean.

This study focuses on the employment effects of military spending versus alternative domestic spending priorities, in particular investments in clean energy, health care and education. We first present some simple alternative spending scenarios, namely devoting $1 billion to the military versus the same amount of money spent on clean energy, health care, and education, as well as for tax cuts w...

A maioria dos métodos para análise de esteróides em sedimentos marinhos é laboriosa, consome grandes volumes de solventes orgânicos (muitas vezes clorados) e produz grandes quantidades de material de descarte. Neste trabalho desenvolveu-se um método de extração com etanol e um “clean up” rápido, que oferece uma alternativa de menor custo e minimiza o uso de solventes clorados. As porcentagens d...
