Johann Christian Andreas Scherf was born 31 October 1818 in Lobenstein, Thuringia, Germany. His parents were Johann Christoph Heinrich Scherf and Susanne Magdelena Horn. He married Ernestina Duenkel, daughter of Johann Kaspar Duenkel and Dorothea Elisabeth Johanne Frankel, in 1840. They had six known children. They emigrated in 1848 and settled in Wisconsin. Ancestors, descendants and relatives lived mainly in Germany, Wisconsin and Iowa.
With this collection of short review papers we would like to present a broad overview of research on poly?uorenes and related heteroanalogues over the last two decades. The collection begins with papers on the synthesis of po- ?uorenesandrelatedpolyheteroarenes, thenreportsphotophysicalproperties of this class of conjugated polymers both at the ensemble and the single chain level, continues with a discussion of the rich solid state structures of poly?uorenes, and ?nally switches to device applications (e.g. in OLEDs). In addition, two chapters are devoted to de?ned oligo?uorenesas lowmolecular weight model systems forpoly?uorenes and also to degradation studies. We feel that this up-to-date collection will be very helpful to all polymer chemists and physicists, and will also aid graduate students interested in this fascinating and still growing area of research, since such a compact overview is only now available. All articles are presented by leading scientists in their ?elds, insuring state-of-the-art coverage of all relevant aspects. Together with the body of references this volume is meant to assist researchers in the daily lab routine. Moreover, Advances in Polymer Science, as an established series of high quality review papers, represents a very appropriate platform for our project.Wehopethatthisshortcollectionwillbeofgreatvaluebothforbeg- ners and established researchscientists inthe?eldofpoly?uorene research.
The celebrated French artist Edme Bouchardon (1698–1762) is primarily known as a sculptor today, but his contemporaries widely lauded him as a draftsman as well. Talented, highly innovative, and deeply invested in the medium, Bouchardon made an important contribution to the European art and culture of his time, and in particular to the history of drawing. Around two thousand of his drawings survive—most of which bear no relation, conceptual or practical, to his sculpture—yet, remarkably, little scholarly attention has been paid to this aspect of his oeuvre. This is the first book-length work devoted to the artist’s draftsmanship since 1910. Ambitious in scope, this volume offers a compelling narrative that effectively covers four decades of Bouchardon’s activity as a draftsman—from his departure for Rome in 1723 as an aspiring student to his death in Paris in 1762, by which time he was one of the most renowned artists in Europe. His accomplished and dynamic style is analyzed and copiously illustrated in a series of five interrelated chapters that serve as case studies, each of which focuses on a coherent group of drawings from a particular period of Bouchardon’s career.
This monograph deals with the species of the families Nemonychidae, Anthribidae and Attelabidae (Curculionoidea, Coleoptera) of Continental Europe north of 52 ° N and of the British Isles. 50 species are included. For each species a short diagnosis and detailed information on the taxonomy, nomenclature, geographic distribution, life habits, hosts and parasites is given. The book contains keys from family level to species and is finely illustrated with over 100 black and white drawings, almost all of which are originals drawn by the author and furthermore with four plates showing 35 representative species skilfully depicted in colour by Birgitte Rubæk. The introductory part provides general information on the taxonomic history, morphology of all life stages, life history and economic importance, comments on phylogeny and classification and some practical hints on how to collect, preserve and identify specimens. In addition lists of hosts and parasites, a catalogue of occurrence by province for the 33 species found in Fennoscandia and Denmark, an extensive list of literature and an index are given. The main objective of the book is to provide a comprehensive systematic treatment of the North European Nemonychidae, Anthribidae and Attelabidae based on richly illustrated identification keys and descriptions combined with up-to-date information on the distribution and biology of individual species. Volume 34 of this series treated the Brentidae. These volumes thus complete the treatment of the four orthocerous weevil families (weevils with straight antennae) within the superfamily Curculionoidea, and are indispensable for anyone - professional or amateur - working with or interested in weevils.

Malaria causes more death and disease than any other parasitic pathogen known today. This multiauthored text covers the important areas of malaria research, particularly focusing on those sectors which are of clinical importance for the understanding of the disease, the parasite, and its vector. The chapter authors are all leading experts within their own particular fields. The biology and molecular biology of the parasite, the clinical spectrum of the disease, the pathogenesis of malaria, and the immunology and emergence of malaria vaccines are some examples of the scientific spheres that are discussed. The book is suitable as a text for graduate students and clinicians as well as researchers at universities and companies involved in treating or studying infectious diseases.
This contributed volume applies the insights of supramolecular chemistry to biomedical applications such as ions/water transport through nano-scale channels, gene therapy, tissue engineering and drug delivery, to cite some of the major investigations.The challenge is to understand the mechanisms of transport through tissues particularly in the therapeutic treatment of a disease where the active drug must be delivered directly to diseased cells without affecting healthy cells. As a result, smaller quantities of active substances can be used to treat the disease. Another interest concerns new ways to administer gene therapy. If genes are often delivered to their target cells by adapted viruses, the supramolecular non-viral ‘vectors’ using dynamic nano-frameworks and nano-structures are presented. In addition, it is important to reconstruct damaged tissues by mimicking natural processes in cells and polymers, such as tissue engineering and self-healing. Different options are here discussed: e.g. hydrogels based on chitosan, a carbohydrate polymer, are proving especially promising for tissue engineering and drug delivery. For controlled delivery of drugs or other biologically active compounds, hydrogels sensitive to the most important stimuli in the human body, such as temperature, pH, ionic strength, glucose and biomolecules released by the organism in pathological conditions have been developed. Finally, to assist and validate the experimental studies, computer modelling and simulations of large-sized molecular structures and systems using different molecular dynamics and quantum mechanical techniques are developed based on the experimental and chemistry synthesis. This book is of great interest for graduate students, researchers and health professionals interested in acquiring a better understanding of the mechanisms of medical treatments. In addition, it provides numerous tools to develop better therapies for human diseases.
