The nasal botfly Oestrus ovis (Diptera, Cyclorrhapha: Oestridae) is a myiasis-causing insect species, which affects the health of sheep, goats and humans. Gravid females are viviparous and larvipositâ€¦ (More)

The technique for lumbar discography is not well standardized. To better understand lumbar pathology, we have developed a consistent, reproducible, and relatively simple procedure for lumbarâ€¦ (More)

Let f : Mn â†’ RN be a submanifold of euclidean space and let Î½0(M) be the maximal parallel and flat subbundle of the normal bundle Î½(M) . Then rankf (M) is the dimension over M of Î½0(M) . One canâ€¦ (More)

We classify all connected subgroups of SO(2, n) that act irreducibly on R. Apart from SO0(2, n) itself these are U(1, n/2), SU(1, n/2), if n even, S 1Â·SO(1, n/2) if n even and n â‰¥ 2, and SO0(1, 2)â€¦ (More)

We prove that a minimal isometric immersion of a KÃ¤hler-Einstein or homogeneous KÃ¤hler manifold into an Euclidean space must be totally geodesic. As an application we show that an open subset of theâ€¦ (More)

Let M âŠ‚ Rn be a submanifold of a euclidean space. A vector d âˆˆ Rn is called a helix direction of M if the angle between d and any tangent space TpM is constant. Let H(M) be the set of helixâ€¦ (More)

Let M be a simply connected complex submanifold of C . We prove that M is irreducible, up a totally geodesic factor, if and only if the normal holonomy group acts irreducibly. This is an extrinsicâ€¦ (More)

We prove, in a purely geometric way, that there are no connected irreducible proper subgroups of SO(N, 1). Moreover, a weakly irreducible subgroup of SO(N, 1) must either act transitively on theâ€¦ (More)

In this paper we give a complete description of the KÃ¤hler immersions of Hermitian symmetric spaces into finite or infinite dimensional complex space forms.
