In 1949, in the aftermath of a devastating war, Eric Birley organised the First Congress of Roman Frontier Studies. His aim was not only to pursue the study of Roman frontiers but also to take a step towards restoring harmony in international relations within this field of research. The pattern was set early on: the exchange of information, networking and friendship. These three elements remain at the core of the approach of those organising and attending the Congress. They are reinforced by the pattern of the meetings, usually held every three years. The programme includes not only lectures but also visits to the local Roman military sites led by appropriate specialists. Over the 75 years since the First Congress, membership has grown enormously with more lecture theatres and more coaches being required every meeting. This publication marks the twenty-sixth Congress at Batumi in Georgia. It aims to help newer members understand the body they have joined; for those who have been attending for longer, it will be a reminder of friendships made and strengthened; for all, the book hopes to be a spur to continuing investigations and research into Rome’s greatest monument, its frontiers; for the moment of publication, it will be a celebration of the twenty-sixth Congress of Roman Frontier Studies.

Towards the end of Caesar’s Gallic War, Rome had reached the Rhine. Since the campaigns under Emperor Augustus (15 B.C.), larger troop contingents were stationed along the river, with focal points around Mogontiacum/Mainz and in northern Switzerland. After the Battle of the Teutoburg Forest (9 AD), when the attempt to occupy all of Germania had failed, the Lower Rhine remained the frontier of the empire’s territory until Late Antiquity. East of the Middle and Upper Rhine, however, the Roman sphere of power was pushed forward several times over a period of almost 200 years, and from 90 AD at the latest, the construction of artificial borders was initiated. When the Roman expansion came to an end around 160 AD, the province was secured in its furthest extension by the “Frontal” or “Outer Upper-Germanic Limes”, which existed until the middle of the 3rd century. This book illustrates the historical and archaeological significance of the Upper Germanic Limes and provides an up-to-date overview of its manifold features in the field.

Organometallic chemistry has shown tremendous success in developing new metal catalysts for industrial applications, e.g. polymerization, organic synthesis or fine chemical synthesis. Nowadays, several active and selective catalysts are known and still, the issue of activity and selectivity remains a challenge. Nature has solved this issue by evolving selective enzymes. These enzymes have excellent catalytic properties with high substrate specificity and product selectivity due to their specialized active site. However, the advantage of high product selectivity comes at the cost of a limited substrate scope. The shape of the active site is crucial for selectivity since it is responsible for highly efficient substrate recognition and orientation together with stabilization of reactive intermediates. The number of enzymatic processes in industry increased due to an increased demand of enantiopure products. The concept of biohybrid catalysts, also named artificial metalloproteins/-enzymes, represents an interdisciplinary field combining biology and organometallic chemistry. The ligands directly attached to the metal center form the first ligand sphere, whereas the second ligand sphere is given by the protein. Constructing artificial metalloproteins by merging these fields allows to combine the attractive features of both, homogeneous and enzymatic catalysis. Chemistry provides a broad library of organometallic complexes, which catalyze numerous challenging (non-natural) chemical reactions with a large substrate scope. Biotechnology provides with the protein scaffold and its second ligand sphere specific tunability for substrates, intermediates or catalysts to facilitate reactions or prevent different selectivities by sitedirectedmutagenesis.

In Deutschland leiden mehr als 20 Millionen Menschen unter Alopezie, dabei werden mehr als 1 Milliarde Euro j hrlich zur Vorbeugung und Behandlung von Haarausfall ausgegeben. Die moderne Wissenschaft hat innerhalb der letzten Jahre gro e Fortschritte im Bereich des Haarausfalls gemacht, diese Erkenntnisse flie en im Ratgeber mit ein. Es werden Ihnen nat rliche Behandlungen, Verhaltensweisen und ganzheitliche Anwendungen vorgestellt, mit denen Sie Ihren Haarausfall nicht nur stoppen, sondern Ihr Haarwachstum anregen k nnen. Sorgen Sie daf r, dass Ihr Haar und Ihre Kopfhaut von innen heraus revitalisiert und gest rkt werden. Eine korrekte Zusammenstellung von Vitaminen, Mineralien, pflanzlichen Wirkstoffen und den richtigen Power-Lebensmitteln st rkt jedes einzelne Haarfollikel. Es gibt aber auch Lebensmittel, die den Prozess des Haarausfalls beschleunigen, diese sollten Sie unbedingt vermeiden. Die Ern hrung ist aber nur einer von mehreren Faktoren, die von Bedeutung sind. Der K rper und speziell die Kopfhaut ben tigen eine ausreichende Blutversorgung, um zu funktionieren. Eine Einschr nkung oder ein Mangel f rdert den Haarausfall. Nur wenn die Kopfhaut ausreichend durchblutet wird, k nnen Ihre Haarfollikel zu 100 % mit den richtigen N hrstoffen versorgt werden. Im Ratgeber finden Sie Techniken und Verhaltensweisen, welche die Durchblutung zur Kopfhaut unterst tzen, sodass kein Haarfollikel mehr verk mmern muss. Sie werden au erdem erfahren, welche Ursachen dem Haarausfall zugrunde liegen und welche unterschiedlichen Arten von Haarausfall vorkommen k nnen. Lernen Sie mit welchen Entspannungs bungen, Pflegema nahmen und Massagetechniken Sie Ihren Haarwuchs unterst tzen k nnen. Wenn Sie alle Ratschl ge aus dem Buch kombinieren, tr gt jede einzelne Komponente zur St rkung Ihres Haares bei. So werden Sie in k rzester Zeit gesundes und kr ftiges Haar erhalten.
