The present invention relates to a nutritional formulation comprising a lipid source, a carbohydrate source, a protein equivalent source, and an emulsifying agent comprising OSA-modified tapioca starch which contains less than about 0. The one or more medical devices each include a receiver operable to receive data signals transmitted over the network area from the broadcast provider. A grain lifter is connected to the second end of the support bar. In this manner, performance characteristics of the transistor can be accurately determined by controlling the respective geometries of the sourcedrain extension regions, the sourcedrain regions, the channel width and an optional trench formed in the underlying substrate. The invention also relates a method for controlling such an apparatus and to a computer program therefor. Also provided is a method of use and can be included as one of the items in a sample collection kit.
