Horizontal lift

In this paper, we obtain vertical, complete and horizontal lifts of paracomplex geometric structures on paracomplex manifolds to its tangent bundle. Also, we obtain integrability on paracomplex tangent bundle.

In Cheeger and Gromoll study complete manifolds of nonnegative curvature and suggest a construction of Riemannian metrics useful in that contex. The main purpose of the paper is to investigate geodesics on the tangent bundle with respect to the Cheeger-Gromoll metric.

Horizontal sliding windows should be treated much the same as sliding glass doors. Header stops in the form of screws with metal washer stacks can be used to remove the space between the top rail of the sash and the track in a way that prevents the sash from being lifted from the track. Once this has been accomplished, a length of wood dowel or special blocking lock bar can be installed on the window to prevent the window from sliding. In some cases, both window sashes slide independently. The outer most sash should be fixed in the track by screws and/or brackets.
