Abstract: A vehicle roof has a framework with longitudinal rails that extend between a front windshield area and a rear window, hatch or door area. The rails are spaced from one another to form an opening between the rails to receive one or more removable roof panels. The removable roof panels have an inner skin and an outer skin. A honeycomb core is sandwiched between the inner and outer skins. The honeycomb core is a non-porous material with strength and lightweight characteristics such as aluminum, polypropylene or the like.

Abstract: A process for the preparation of a compound of formula I: wherein R is a hydrogen or a C1-6 alkyl group which is straight chain, branched or cyclic, with or without an oxygen, nitrogen or sulphur heteroatom anywhere in the chain or ring by reacting a compound of formula II: with a source of hydrogen selected from either hydrogen or water in the presence of a mixture of at least two catalysts selected from nickel, raney nickel, and palladium, at a pH below 7.0 in a solvent medium comprising an alcohol having a carbon chain length of up to 3.
