Present valueIn economics and finance, present value (PV), also known as present discounted value, is the value of an expected income stream determined as of the date of valuation. The present value is usually less than the future value because money has interest-earning potential, a characteristic referred to as the time value of money, except during times of zero- or negative interest rates, when the present value will be equal or more than the future value. Time value can be described with the simplified phrase, "A dollar today is worth more than a dollar tomorrow".
Minimal Supersymmetric Standard ModelThe Minimal Supersymmetric Standard Model (MSSM) is an extension to the Standard Model that realizes supersymmetry. MSSM is the minimal supersymmetrical model as it considers only "the [minimum] number of new particle states and new interactions consistent with "Reality". Supersymmetry pairs bosons with fermions, so every Standard Model particle has a superpartner yet undiscovered. If discovered, such superparticles could be candidates for dark matter, and could provide evidence for grand unification or the viability of string theory.
ProcessusLe mot processus vient du latin pro (au sens de « vers l'avant ») et de cessus, cedere (« aller, marcher ») ce qui signifie donc aller vers l'avant, avancer. Ce mot est également à l'origine du mot procédure qui désigne plutôt la méthode d'organisation, la stratégie du changement. En anatomie, un processus est une partie proéminente d'un organe ou un relief osseux aussi appelé apophyse. En écologie et biologie, les processus environnementaux, ou processus écosystémiques, sont des mécanismes ou des événements reliant les organismes à leur environnement.
