1 It provides orientable halogen task lighting, and its elegant counterweight and arm system keep the head constantly parallel to the table.

2 This paper establishes some formulas on orientable closed surfaces in 3-dimensional space forms.

3 As a powerful, orientable, clean and efficient light source, laser has leaded a vitally important innovation in various fields since emergence.

4 Integral absolute mean curvature is introduced to describe average curving of an orientable closed surface.

5 First the model is subdivided into simple meshes that are orientable and manifold.

6 In Chapter 1, we introduce the concepts and background of the maximum genus of graphs and graph embedding in orientable surface briefly.

7 This paper studies the maximum genus of a graph $G $ only in term of some embedding of $G $ in an orientable surface, not of its other invariants, and gives the maximum genus of this kind of graphs.

8 The main human rights thoughts of European Union is the American-European Orientable Doctrine.

9 In this paper, the lower bound problems of the maximum genus and the genus distributions of digraphs in orientable surfaces are studied.

10 Well, I claim this curve actually bounds another surface that is orientable.
