Ehi (spirit)
''Ehi'' is the name of a personal spirit in some West African religious beliefs, especially in Edo Nigeria and Benin. Ehi means "genius", but it also means "angel" in some Nigerian languages and refers to a spirit possessing a man, similar to a guardian angel. Furthermore, Ehi means "gift" in the Idoma language of Nigeria. ''Ehi'' is a component of a person that remains with the supreme deity Osa. A person's ''ehi'' guides them through their life in the ''agbon'', or material world, while interacting with other spirits in the ''erinmwin'', or Spirit world (Spiritualism), spirit world. The ''ehi'' remains with the person during the day, and returns to report to Osa at night. ''Ehi'' is viewed as a cult in parts of western Africa with a "moderated initiative" where many believe that lack of success can be blamed on the ''Ehi'' possessing a man. The ''Ehi'' is said to be "constantly sacrificed" in gratitude for success or for guidance in difficult times. Bradbury says of it, "Close a ...

Endurmenntun Háskóla Íslands
Endurmenntun Háskóla Íslands or EHÍ is a continuing education centre operated by the University of Iceland The University of Iceland ( is, Háskóli Íslands ) is a public research university in Reykjavík, Iceland and the country's oldest and largest institution of higher education. Founded in 1911, it has grown steadily from a small civil servants' s .... Unlike its parent institution, it does not receive public funding and it entirely funded by school fees. It offers a variety of career enhancement- and personal enrichment courses in fields such as finance, administration, information technology, education, tourism, language and culture. These range from single courses to full degree programmes. Teaching is provided by University of Iceland staff, local industry specialists, and guests from abroad.

Energy Helicity Index
:''This page is about helicity in fluid dynamics. For helicity of magnetic fields, see magnetic helicity. For helicity in particle physics, see helicity (particle physics).'' In fluid dynamics, helicity is, under appropriate conditions, an invariant of the Euler equations of fluid flow, having a topological interpretation as a measure of linkage and/or knottedness of vortex lines in the flow. This was first proved by Jean-Jacques Moreau in 1961 and Moffatt derived it in 1969 without the knowledge of Moreau's paper. This helicity invariant is an extension of Woltjer's theorem for magnetic helicity. Let \mathbf(x,t) be the velocity field and \nabla\times\mathbf the corresponding vorticity field. Under the following three conditions, the vortex lines are transported with (or 'frozen in') the flow: (i) the fluid is inviscid; (ii) either the flow is incompressible (\nabla\cdot\mathbf = 0), or it is compressible with a barotropic relation p = p(\rho) between pressure p and density ...
