The invention relates in part to fused tricyclic compounds having certain biological activities that include, but are not limited to, inhibiting cell proliferation, modulating protein kinase activity and modulating polymerase activity. The laminated material also has a film-like surface on a selected surface portion of the fabric layer which is formed by applying heat to the selected surface portion. A donor graft of a size corresponding to the recipient socket is harvested from a synthetic specimen made of a synthetic tissue material, such as poly alcohol hydrogel. The content server transmits the content across the Internet according to the published schedule via a multicast transmission designated for a particular multicast group. Multi-layer materials and optoelectronic devices including such cross-linked composites are also disclosed. Additionally, the invention relates to a spraying device for spraying several surfaces that are separated from each other by means of grooves andor joints, such as, inter alia, paving stones, tiles, Bangkirai andor building bricks, wherein the spraying device comprises two or more spray heads, each of which produces a water jet.
