This Festschrift in honour of Professor Dr. Dr. h.c. P. Michael Schmitz covers theoretical as well as empirical works on challenges prevailing in the food and agricultural sector. Discussions of conflicts between social and ecological requests of citizens and market outcomes are provided. The contributors discuss options of policy interventions as well as their limitations. Empirical facts that can contribute to a more evidence based policy formation are also presented. The book itself consists of two parts: "agri-food markets and policies" and "agriculture, trade and development". Topics covered are moral, markets and policies, farm animal welfare, fat taxes, agricultural derivatives markets, future food value chains, free trade agreements, food security, food waste and climate change.

1.1 Preface Organic chemistry had its origin in chemicals which are synthesized by living cells. These chemicals consist of molecules whose skeletons are built up of carbon atoms. The remaining valences are connected with ligands such as hydrogen, halo gens, -OH, ==O, -NH . Some of the skeletal carbon atoms can be replaced by non 2 metals such as oxygen, nitrogen, or sulfur {"heteroatoms"}. It is characteristic for the living world, not to be in a crystalline state. However it is possible to obtain single crystals from many organic compounds both of natural and synthetic origin. For a number of years the physics and chem istry of these crystals have stimulated fundamental research on a rapidly growing scale. The great variety of possible organic structures {as compared to inorganics} opens up a large field of new materials and of novel material properties; for previous literature reviews and data compilations see 1-40) and Chap. 6. The art of producing good and pure organic single crystals has developed hand in-hand with the ever growing requirements of basic research, arising from its interest in fundamental interactions in the solid state. Interactions manifest themselves in a very detailed way by energy transfer."

Mit einem kurzgeschlossenen Skoda rasen Sebastian und ich durch das ukrainische Lviv. In der sechsten Liga Sachsens entdecke ich die mittlerweile 43-jahrige Torhuterlegende Tomislav Piplica wieder. Die Polizei raumt den Fanblock von Sigma Olmutz in der Halbzeitpause bis auf den letzten Mann und im Moskauer Hotel sorgt eine leicht bekleidete Dame fur Aufsehen.
