The biorefinery concept in its modern meaning has emerged after it has become apparent that biofuel production from non-food biomass is struggling for economic viability. Lignocellulosic biomass is more recalcitrant and more complex than the starch-based feedstocks used for food. The former, therefore, calls for a more complex approach to its utilization. This chapter reflects MetGen’s vision of the future development of biorefineries. We will discuss the zero-waste approach to lignocellulosic biomass utilization and various ways to valorize the resulting streams to boost the economic viability of the biorefinery. We will mostly explore the relevant enzyme-based approaches and will make a special focus on lignin valorization. Enzymatic and cell-based approaches to sugar valorization will be discussed as well.

This article aims to describe the personality of the talented Czech linguist and distinctive philosopher Alois Richard Nykl, with a special focus on his repeated stays in Mexico as well as his reflection of the post-revolutionary developments there. The unpublished travelogue “Present-Day Mexico”, complemented with the author’s short texts and other archive materials from Nykl’s estate, served as the initial material for this study. This has resulted in a colourful and multilayered picture of the Mexican society in the 1920s as well as Nykl’s complex personality. After over 90 years, his analyses of the contemporary situation and estimates of the future development of Mexico provide an opportunity for an interesting comparison with the present state of affairs.

The article examines the state of the Holocaust historiography in Ukraine for the period of 2010 – beginning of 2014. The review analyzes activities of major research and educational organizations in Ukraine which have significant part of projects devoted to the Holocaust; main publications and discussions on the Holocaust in Ukraine, including publications of Ukrainian authors in academic European and American journals. The article illustrates contemporary tendencies and conditions of the Holocaust Studies in Ukraine, defines major problems and shows perspectives of the future development of the Holocaust historiography in Ukraine.

This paper,first presented on 21 October 1995 at ajoint seminar ofthe Scottish Law Commission and the Faculty of Law, University of Edinburgh, on the subject of breach of contract, considers the future development of the law in this area, first by considering its history and current state in comparative terms and drawing the conclusion that it is characterised by a mixture of Civilian and Common Law elements; second, by comparing Scots law with the provisions on breach contained in recently published proposals for a harmonised law of contract (the UNIDROIT Principles of International Commercial Contracts, the Principles of European Contract Law prepared by the Lando Commission, and the draft “code”for the United Kingdom prepared on behalf of the English Law Commission by Harvey McGregor in the late 1960s) and in international conventions on the sale of goods. Although Scots law emerges reasonably wellfrom this exercise, there are a number of points to be taken on board in any future reform, as well as some insights into important underlying principles.

A practical and concise total synthesis of tricyclic ketone 7 (CDE ring), a valuable intermediate for the synthesis of racemic camptothecin and analogs, was described (8 chemical steps and 29% overall yield). The synthesis starts with two inexpensive, readily available materials and is operationally simple to perform. It is worth mentioning that the reported protecting group-free synthesis, with advantages of a short route, would be helpful for the future development of industry-scale syntheses of camptothecin-family alkaloids.
