Abstract: A makeup kit is disclosed which contains all of the essentials in one unit. The kit can be customized for users of different hair colors and complexions. A limited number of kit types will accommodate all users. Decision trees are provided to assist users in selecting the optimal kit type. Selection of the optimal kit is facilitated by the provision of color or gray swatches in conjunction with a decision tree to categorize skin shade. A technique for categorizing potential users for other makeup kit systems is also disclosed.

Abstract: A new rotating cell vessel and method of use have been developed. The vessel is constructed of materials which are permeable to oxygen and carbon dioxide, and when rotated horizontally suspend the contents, cells and particle substrates, in a liquid medium with a low turbulence, low shear fluid environment. The vessel walls are made at least partially of gas permeable material. The vessel is rotated in a horizontal plane to suspend the cells and substrate particles in a low turbulence liquid nutrient medium. Oxygen continuously diffuses through the permeable vessel material and through the cell culture liquid medium to provide the needed oxygen to the cells. Carbon dioxide diffuses through the cell culture medium and through the vessel wall, removing this waste product from the cell culture. The vessel is uniquely designed to be simply constructed.
