This book combines knowledge of process dynamics and basic control theory to analyze a range of bioprocesses and drug-release devices. The book addresses issues and solves problems that dominate both fields (i.e., biological sciences and release devices.) Many of the textbooks written on this topic usually focus on specific topics (e.g., systems biology, control of fermentation processes), as a result, undergraduate chemical engineering students are not exposed to a range of diversified problems in biological sciences. This book builds on the new focus of providing problems in the biological area. In addition, unified theories and step-by-step problem solving procedures are provided. A unique feature of the book is the application of control theory to analyze controlled-release devices. An expected outcome of the proposed perspective is an enrichment of fundamental concepts and the development of an application-oriented environment. For example pharmaceutical companies, specializing in the production of therapeutics using biological processes, are the first beneficiaries. A qualified labor force, with competencies in process analysis, design and control will assure that the target quantity and quality of the end-products are met and in line with federal and state regulations.
