Natural Products, broadly defined as high value chemical entities derived from plants or microbial sources, have been known and exploited for many years. In recent years, as the need for higher potency and predictability of such products has increased, more sophisticated concentration and isolation procedures have been developed. With the passage of time, such procedures have been rationalized in terms of scientific principles but, in general, theory has followed behind practice, leading at any given time to an absence from the literature of methods which are truly state of the art. Downstream Processing of Natural Products: A Practical Handbook is a highly practical manual which addresses this issue, and guides researchers and industrial workers through the many potential pitfalls of natural product isolation. The contributors to this volume, all of whom have wide practical experience in this field, present state-of-the-art techniques and observations. The three main stages of natural product purification are covered, namely product release, capture, and purification, and both proteins and secondary metabolites are covered. There is special mention of the requirements of the regulatory authorities with respect to Good Manufacturing Practice, and practical guidance is given on scale-up procedures and process scale instrumentation. Downstream Processing of Natural Products: A Practical Handbook will provide essential practical guidance to all those involved in natural product isolation. This includes academic and industrial researchers, postgraduate students and technicians working in the biotechnology field.

Over the last few years, financial statement scandals, cases of fraud and corruption, data protection violations, and other legal violations have led to numerous liability cases, damages claims, and losses of reputation. As a reaction to these developments, several regulations have been issued: Corporate Governance, the Sarbanes-Oxley Act, IFRS, Basel II and III, Solvency II and BilMoG, to name just a few. In this book, compliance is understood as the process, mapped not only in an internal control system, that is intended to guarantee conformity with legal requirements but also with internal policies and enterprise objectives (in particular, efficiency and profitability). The current literature primarily confines itself to mapping controls in SAP ERP and auditing SAP systems. Maxim Chuprunov not only addresses this subject but extends the aim of internal controls from legal compliance to include efficiency and profitability and then well beyond, because a basic understanding of the processes involved in IT-supported compliance management processes are not delivered along with the software. Starting with the requirements for compliance (Part I), he not only answers compliance-relevant questions in the form of an audit guide for an SAP ERP system and in the form of risks and control descriptions (Part II), but also shows how to automate the compliance management process based on SAP GRC (Part III). He thus addresses the current need for solutions for implementing an integrated GRC system in an organization, especially focusing on the continuous control monitoring topics. Maxim Chuprunov mainly targets compliance experts, auditors, SAP project managers and consultants responsible for GRC products as readers for his book. They will find indispensable information for their daily work from the first to the last page. In addition, MBA, management information system students as well as senior managers like CIOs and CFOs will find a wealth of valuable information on compliance in the SAP ERP environment, on GRC in general and its implementation in particular.

This brief presents the main aspects of the response functions theory (RFT) for molecular solutes described within the framework of the Polarizable Continuum Model (PCM). PCM is a solvation model for a Quantum Mechanical molecular system in which the solvent is represented as a continuum distribution of matter. Particular attention is devoted (i) to the description of the basic features of the PCM model, and (ii) to the problems characterizing the study of the response function theory for molecules in solution with respect to the analogous theory on isolated molecules.

This book covers broad aspects of the chemistry of π-stacked polymers and low-molecular-weight molecules, from synthesis through theory.  It is intended for graduate students and researchers in academia and industry and consists of chapters written by renowned scientists who have made significant contributions to this field in the past decade.  π-Stacked polymers and low-molecular-weight molecules are expected to replace main-chain conjugated polymers such as polyacetylenes and polythiophenes as organic conducting and energy-transferring substances that are important as materials for photo-electronic applications.  π-Stacked polymers and molecules have significant advantages over main-chain conjugated polymers, i.e., high solubility in solvents, large freedom in molecular design, and colorless nature.
