Tropical fishes like Leporinus macrocephalus Garavello & Britski, 1988 (piauçu) and the hybrid tambacu (Piaractus mesopotamicus Holmberg, 1887 pacu male x Colossoma macropomum Cuvier, 1818 tambaqui female) were experimentally infected with four inocula of trophonts of Ichthyophthirius multifiliis Fouquet, 1876 (Protozoa, Ciliophora) and the infection level was evaluated. Each one of twelve experimental units consisted of a tank with 200 liters of water and two specimens of each kind of fish. The following treatments were designed to each tank, in triplicate: 8, 16,32 and 64 trophonts. After 8 days of exposure the fishes were killed and the number of trophonts was counted at a stereoscopic microscope. This assay showed to be feasible at tropical conditions and was able to show that tambacu was more susceptiblc than piauçu.

We present a general catalyst design to synthesize ultrahigh density, aligned forests of carbon nanotubes by cyclic deposition and annealing of catalyst thin films. This leads to nanotube forests with an area density of at least 10(13) cm(-2), over 1 order of magnitude higher than existing values, and close to the limit of a fully dense forest. The technique consists of cycles of ultrathin metal film deposition, annealing, and immobilization. These ultradense forests are needed to use carbon nanotubes as vias and interconnects in integrated circuits and thermal interface materials. Further density increase to 10(14) cm(-2) by reducing nanotube diameter is possible, and it is also applicable to nanowires.
