The ASI Quarks, Leptons and Beyond, held in Munich from the 5th to the 16th of September 1983 was dedicated to the study of what we now believe are the fundamental building blocks of nature: quarks and leptons. The subject was approached on two levels. On the one hand, a thorough discussion was given of the status of our knowledge of quarks and leptons and their interactions, both from an experi mental and a theoretical standpoint. On the other hand, open problems presented by the so called standard model of quark and lepton interact ions were explored along various ways that lead one beyond this frame work. One of the principal predictions of the standard model is that weak interactions are mediated by heavy Wand Z vector bosons. These particles were discovered in 1983 at CERN and their relevant proper ties were discussed at the ASI by C. Rubbia. Further theoretical predictions concerning these Z and W bosons, yet to be checked by future experimentation, were discussed by G. Altarelli with a view of seeing where the standard model might fail and new physics ensue. The strong interactions of quarks, based on Quantum Chromodynamics (QeD), are presumed to cause the quarks to bind into hadrons. Pro gress in attempts to calculate the observed hadronic spectrum, ab initio, starting from QCD and employing lattice methods were reviewed at the ASI by P. Hasenfratz.

It is a new day, a new season for women at this unique time in history. With this new season comes a responsibility and opportunity to live life to its fullest potential . . . but how, exactly, can women wake up to all the possibilities and make the right choices to make each day matter? Popular author and speaker Holly Wagner is calling women to set aside 90 days to awaken to the life God has waiting for each of his daughters. Based on Holly's book Warrior Chicks and on Proverbs 31, these daily devotions go right to the heart of every woman's hopes and dreams for her life, and will stir readers to claim their freedom as heiresses to God's promises. Each reading includes action steps to help women make an impact on and in their day and questions to inspire deeper meditation.

In the past ten years there was a worldwide trend towards increased use of Tunnel Boring Machines (TBM''s). This trend covers a broad variety of applications ranging both from small diameters for sewers and other utilities to large diameters for double track railway and even three-lane highway tunnels. The response to this has been the development of both hard rock machines in the direction for application in soft ground, and soft ground TBM''s to be used in soft rock. Parallel to the technical development of TBM''s towards applications for longer tunnels, running through changing geological conditions, there are needs for the development of lining methods. ''TBM Tunnel Trends'' an international lecture serie collection, aims to present the latest scientific and practical state of the art of TBM tunnelling, taking into consideration interactions between machinery and lining. 26 international highly recognized papers.

In znodern pharznacognosy chemical and physical-cheznical methods are being used znore and more for the investigation of medicinal plants. This important fact and the increasing involvement of chemistry, biocheznistry and botany in pllarmaceuti- cal, znedicinal and general biological questions usher in a new epoch in the disco- very of medicinal substances and the development of drugs derived from the plant kingdom. One of the guiding ideas of the first "Syznposiuzn on Pharznacognosy and Phytocheznistry" was to promote these developments, to provide an additional sti- znulus and to establish a basis for better coordination and cooperation. The organizers intended that most of the modern branches of research into natural products should be represented, including analysis, structural chemistry, chemi- cal synthesis and biosynthesis, as well as pharmacology. Since the plenary lectures also reflect the present level of knowledge in some iznportant areas of natural products research, this volume will constitute an important source of information for an scientists interested in natural substances.Its usefulness is much enhanced by the fact, that the voluzne will appear only four znonths after the Symposiuzn, thanks to the kind assistance of Dr. K. F. Springer of Springer-Verlag. The organizers extend cordial thanks to an the participants for their interesting contributions and herewith invite them to attend the second Syznposium in 1973. We want to express our special thanks to Miss Seitz and Miss Hagendorn for their rapid and conscientious preparation of the manuscripts for offset-printing.

Bacterial CpG-DNA sequences not only serve for genetic information but act as "danger" signal to alert immune cells such as macrophages and dendritic cells. CpG-DNA directly causes activation of these members of the innate immune system yielding in up-regulation of co-stimulatory molecules and pro-inflammatory cytokines. As such they act as "natural" adjuvants to promote protective Th1 polarized T cell immune responses. This book is the first comprehensive review of the data emerging in this field.

Never has so much progress been reported in immunology as at this congress. The full impact of new technologies, developed since the late 1970s, has come to fruition: gene isolation, mutation, transfection and expression, protein structure and peptide synthesis, cell cloning, hybridization and monoclonal antibodies, CD serology, SCID and transgenic mice, modern immunomudulation and vaccines. An overwhelming mass of data has accumulated over the last years. The reports are up-to-date and outstanding, to a degree no journal will ever achieve, and the results are presented in a concise and lucid way. This report will serve as a guideline for generations of immunologists to come. Hundreds of new alleys have been opened, an abundance of research tools and goals are pointed to. This volume is a treasure trove of explorations ahead of our time - it is exciting reading. This progress report presents outstanding contributions, worth many prizes - a feature which is unusual for proceedings volumes. Immunology is exhibited at its best: an exciting research area and a rewarding subject to study for the benefit of mankind - today more than ever!

The verrucarins and roridins are secondary metabolites of the soil fungi Myrothecium verrucaria (Albertini et Schweinitz) Ditmar ex Fries and Myrothecium roridum Tode ex Fries. The species Myrothecium belongs to the fungi imperfecti, order of Moniliales, family Tubercularia- ceae (30, 17, 32). The distinction between these and other closely related fungal species is difficult. It has been studied and discussed by various authors (82, 16, 55, 75, 62, 43). Myrothecium species are parasitic on leaves of Gardenia, tomatoes, violets, kidney beans, snapdragons and other common plants. They are also found on decaying tissue and in soil. It was known earlier that cultures of the two species mentioned exhibit cellulolytic properties due to the presence of a very active cellulase which was used for the treatment of cellulose during the production of textiles [for leading references see (42, 66)]. The first investigation of the secondary metabolites of these micro- organisms was carried out by BRIAN and MCGOWAN (16). They isolated a crystalline compound, designated as glutinosin and assigned the formula C4sH60016, from cultures of Metarrhizium glutinosum S.Pope, which in fact is a Myrothecium species (82, 55). Glutinosin exhibited anti- fungal activity. Eight years later BOWDEN and SCHANTZ (14) described the isolation and characterization of a dermatitic or skinirritating crystal- line compound melting at 38 , and possessing the formula C H 04, 1s 22 from culture filtrates of Myrothecium verrucaria. They suspected the presence of additional biologically active substances.

Die 5. "Verhandlungen der Gesellschaft fur Okologie" enthalten die Vortrage der vom 22. bis 24. September 197 5 in Wien durchgefuhrten J ahrestagung. Schwer- punktsmassig behandeln die Referate alpine und arktische Okosysteme, die okologi- schen und genetischen Voraussetzungen fur das Leben in Trockengebieten sowie limnische Okosysteme. Durch die Berucksichtigung der diese Systeme tangierenden IBP- und MAB-Forschungsprogramme liefern sie zugleich auch aktuelle Informa- tionen uber laufende Forschungsprojekte unserer Osterreichischen und schweizer Kollegen. Struktudle und energetische Untersuchungen uber einzelne Okosysteme, Biozo- nosen und Populationen stehen dabei im Vordergrund. Die vorgelegten Arbeiten verdeutlichen, dass jedes lebendige System uber die Kenntnis seiner Struktur, Funk- tion und Geschichte Informationen zu einem tieferen Verstandnis des von ihm belebten Raumes liefert. Sie zeigen, dass letztlich jeder Suche nach "Belastungsindi- katoren" und "okologischen Kriterien" die Frage nach dem Informationsgehalt von Organismen und lebenden Systemen sowie deren Reaktionen auf endo- und exogene Faktoren zugrunde liegt.Sowohl aus Veranderungen der Areal- und Okosysteme, als auch aus Wandlungen von Biozonosen und deren Reaktionen wurden Ruckschlusse auf die diese Veranderungen auslosenden Faktoren gezogen. Populationen und Bio- zonosen reagieren naturgemass nach eigenen Regeln, konnen jedoch nur existieren, wenn sie bestandig auch Informationen uber andere Komponenten aus ihrem Ver- breitungsgebiet speichern und verarbeiten. Diese adaptiven Fahigkeiten der unter- suchten Arten und Systeme sind jedoch noch weitgehend unbearbeitet. Hier klafft eine echte Lucke, die den Transfer okologischer Daten z. B. in di. c Landesplanung erschwert. Die Qualitat jeder Planung hangt weitgehend von den eingesetzten okologischen, sozialen und wirtschaftlichen Erhebungsdaten ab.
