Abstract: Animal cells are described which can be infected by influenza viruses and which are adapted to growth in suspension in serum-free medium.

Abstract: A method of storing tomato paste and like corrosive materials, a method for lining drum shells, lids and filling hole covers, and a lining therefore, prior to the assembly of these parts to make steel drums. The above are carried out by pre-treating such parts by spraying with an alkaline solution, iron phosphate and also can be treated with a standard rust inhibitor. The interiors of the drum parts are coated by electrostatic spray application with a thermosetting epoxy-based powder to a specified thickness which eliminates subsequent cracking and subsequent vulnerability to destructive substances such as tomato paste and other more corrosive chemicals. The drum parts are preheated prior to the application of the powder to accelerate the fusion of the powder particle coating as well as reduce the associated material application problems. After application of the powder to the container interiors, the components are again subjected to oven temperatures to set and cure the coating.
