Abstract: Synthetic processes are provided wherein oligomeric compounds are prepared having phosphodiester, phosphorothioate, phosphorodithioate, or other covalent linkages. The oligomers have substantially reduced exocyclic adducts deriving from acrylonitrile or related contaminants.

Abstract: The present invention relates to a composition for forming fibers of synthetic detergents. The composition includes a synthetic wax, a primary surfactant added to the synthetic wax, and a secondary surfactant added to the synthetic wax. The present invention also relates to a method for developing fibers of synthetic detergents. The method includes adding a primary surfactant to a synthetic wax; adding a secondary surfactant to the synthetic wax; and forming the synthetic wax into fibers. In another form, the present invention relates to a fiber that includes a synthetic wax, a primary surfactant embedded in the synthetic wax, and a secondary surfactant embedded in the synthetic wax. The present invention also relates to a fibrous matrix of synthetic detergents. The fibrous matrix includes fibers formed of a synthetic wax and a primary surfactant embedded in the fibers. The fibrous matrix further includes a secondary surfactant embedded in the fibers.

Abstract: The invention relates to various intraflagellar transport (IFT) polypeptides and the nucleic acids that encode them. The new IFT particle polypeptides and nucleic acids can be used in a variety of diagnostic, screening, and therapeutic methods.

Abstract: A cyclone which includes an upper cylindrical portion opening into the wider end of a lower frustro-conical portion, with a primary air inlet such that the inlet air is substantially tangential to the circumference of the cyclone, and an exhaust outlet at or adjacent the top of the cylindrical portion; a control valve is associated with the exhaust outlet and can be used to partially or completely shut off the outlet; a secondary air inlet is associated with the narrow end of the frustro-conical portion and is provided with an air flow stabilising device adapted to admit a stream of air substantially along the longitudinal axis of the cyclone; also including means for withdrawing processed product from the frustro-conical portion.
