The vitamin B 2 content of foods has historically been determined as total riboflavin (TRF), and the most common method of TRF analysis has been the AOAC standard fluorometric procedure. A modification of this method to permit the use of flow injection analysis (FIA) is reported here. A number of foods were analyzed and the results generally agreed with the published values.

Since the initial publication in 1994, Coordination Theory has been referenced in nearly 300 journal articles, book chapters, conference papers and theses. Coordination Theory provides an approach to a core problem in HCI: analyzing group work to suggest alternative approaches involving computer support. Coordination Theory suggests identifying the dependencies between the tasks the different g...

The stationary solution of Smoluchowski’s coagulation equation with injection is found analytically different exponentially decaying source terms. latter involve a factor in the form power law function that plays decisive role forming steady-state particle distribution shape. An unsteady analytical to obtained for initial without injection. approximate constructed by stitching and final (steady...
