Band XIa enth??lt allgemeine Kapitel zur Systematik, Klassifikation, Ethnobotanik, Phytochemie und Chemotaxonomie der Leguminosen. Die allgemeinen chemischen Kapitel sind familiencharakteristischen Prim??r- und Sekund??rstoffen und einigen aus der Familie bisher eher sporadisch bekannt gewordenen Stoffklassen gewidmet. Insgesamt enth??lt dieser Band ??ber 2000 Literaturhinweise. Hegnauers Chemotaxonomie ist ein unentbehrliches Handbuch f??r alle naturwissenschaftlichen Disziplinen, die sich mit dem Chemismus der Pflanze - auch ausserhalb botanisch-systematischer Fragen - befassen. Text und Literaturhinweise geben gemeinsam ein Bild unseres gegenw??rtigen Wissensstandes von den Stoffwechseleigenarten der behandelten Pflanzensippen. Die Ergebnisse der Naturstoffchemie, der vergleichenden Phytochemie und der Biogeneseforschung werden zum Aufbau einer systematischen Chemie der Pflanzen, also einer mit Stoffwechselmerkmalen arbeitenden Hilfs-wissenschaft der systematischen Botanik, verwendet. Der auf zwei Teilb??nde angelegte Band XI dieses Standardwerkes beleuchtet die Relevanz der Inhaltsstoffe der Leguminosen f??r die Fachgebiete der Systematik, Physiologie, Agrarwissenschaften, Pharmazie, Toxikologie, Medizin, ??kologie und Ethnobotanik. Mit Band XIa der Chemotaxonomie der Pflanzen liegt ein unverzichtbares Arbeitsmittel und Nachschlagewerk vor f??r alle, deren Interesse den Leguminosen gilt. Es richtet sich ??ber den Kreis der Pflanzentaxonomen, Pflanzenphysiologen und Naturstoffchemiker hinaus an Pflanzen??kologen, Agrar- und Ern??hrungswissenschaftler sowie Arzneimittelforscher. Die kosmopolitische Familie der Leguminosen, zu der neben zahlreichen Nahrungs- und Futterpflanzen vieleweitere wirtschaftlich bedeutende Kultur- und Zierpflanzen geh??ren, umfasst etwa 600 Gattungen beziehungsweise 13'000 Arten.

Der Begriff "BIONIK" wird gerne als Kunstwort gekennzeichnet, zusammengesetzt aus BIOlogie und TechNIK. Bionik stellt einerseits ein Fach dar, in dem geforscht und ausgebildet wird, und kennzeichnet andererseits eine Sichtweise, namlich die des "Lernens von der Natur fur die Technik". Daruber sind in der Zwischenzeit neben popular wissenschaftlichen Werken eine Reihe von Fachbuchern erschienen. Werner Nachtigall hat darin mit der 2. Auflage seines bei Springer erschienenen Buchs "BIONIK - Grundlagen und Beispiele fur Ingenieure und Naturwissenschaftler" einen Meilenstein gesetzt. In diesem Buch kennzeichnet er die Untergliederung des Fachs und bespricht detailliert dessen Forschungsgegenstande. Dagegen fehlte bislang eine Darstellung, die sich mit den erkenntnistheoretischen Grundlagen wie mit der pragmatischen Vorgehensweise der Bionik systematisch befasst, die ja mit der ihr eigenen Prinzip-Abstraktion zwischen der belebten Welt als Vor-Bild und der technischen Umsetzung als Ab-Bild vermitteln will. Das vorliegende Werk schliesst diese Lucke mit drei grossen Abschnitten: Biologische Basis: Erforschen, Beschreiben, Beurteilen. - Abstraktion biologischer Befunde: Herausarbeiten allgemeiner Prinzipien. - Umsetzung in die Technik: Prinzipvergleich, Konzeptuelles, Vorgehensweise.

The natural, biological, medical, and related sciences would not be what they are today without the microscope. After the introduction of the optical microscope, a second breakthrough in morphostructural surface analysis occurred in the 1940s with the development of the scanning electron microscope (SEM), which, instead of light (i. e. , photons) and glass lenses, uses electrons and electromagnetic lenses (magnetic coils). Optical and scanning (or transmission) electron microscopes are called "far-field microscopes" because of the long distance between the sample and the point at which the image is obtained in comparison with the wavelengths of the photons or electrons involved. In this case, the image is a diffraction pattern and its resolution is wavelength limited. In 1986, a completely new type of microscopy was proposed, which, without the use of lenses, photons, or electrons, directly explores the sample surface by means of mechanical scanning, thus opening up unexpected possibilities for the morphostructural and mechanical analysis of biological specimens. These new scanning probe microscopes are based on the concept of near-field microscopy, which overcomes the problem of the limited diffraction-related resolution inherent in conventional microscopes. Located in the immediate vicinity of the sample itself (usually within a few nanometers), the probe records the intensity, rather than the interference signal, thus significantly improving resolution. Since the most we- known microscopes of this type operate using atomic forces, they are frequently referred to as atomic force microscopes (AFMs).

This book combines orthopedists' and radiologists' perspectives to provide a comprehensive overview of the rapidly expanding use of ultrasound in orthopedic surgery. It also highlights the growing awareness of the potential of this non-invasive and portable, real-time imaging tool, which has led to its inclusion in the minimally invasive toolkit of upper limb surgeons.The book is divided into five parts - shoulder, elbow, forearm, hand and wrist and fingers. Each part focuses on a particular anatomic region or joint, carefully analyzing the sonoanatomy of its nerves, tendons and bones. For each region, experienced experts illustrate how to perform specific techniques under ultrasound control, ranging from classic procedures, like carpal tunnel release, to the treatment of less common conditions. Covering all the basic and practical aspects of this innovative, multi-disciplinary approach, as well as future perspectives, this unique book is a must-read for all orthopedists, radiologists, sports physicians and physiotherapist wanting to gain insights into this promising field.

DNA microarrays, or biochips, are small glass chips embedded with ordered rows of DNA and by providing a massive parallel platform for data gathering represent a fundamental technical advance in biomedical research.

It was one of the great moments of humanity when Wilhelm Conrad Roentgen (1845- 1923) discovered a new kind of radiation on 8 November 1895. He himself modestly called them "X-rays". Roentgen's name and his rays became world famous. On 10 December 1901, Roentgen received the first Nobel Prize in Physics. X-rays have lost none of their appeal since then. They still permeate all areas of science, technology and medicine and accompany us in our everyday lives. However, Roentgen's scientific work cannot be reduced to this one great discovery alone. He was an excellent natural scientist, and his spirit of research is still an example for many scientists today. Roentgen's very special interest in precision physics is also more topical than ever. This carefully curated volume offers a multifaceted view of an outstanding natural scientist and provides insights into his personal legacy.

This open access book is only an introduction to show that radiation and radioisotopes (RI) are premier tools to study living plant physiology which leads to new findings. Who had ever imagined that we could see water in a plant? Who had ever imagined that we could see ions moving toward roots in solution? Who had ever imagined that we could see invisible gas (CO2) fixation and movement in a plant? These studies demonstrated for the first time that water, ions and gas can be visualized in living plants, which could be hardly seen by anyone before. This publication summarizes the results obtained by Nakanishi's lab in The Univ. of Tokyo, based on her original concept and her original tools or systems. It is useful for professional scientists, plant physiologist, and those studying plant imaging. The chapters demonstrates the innovative imaging work of the author, using radioactive tracers and neutron beam to follow the absorption and transport manner of water as well as major, minor, and trace elements in plants. Through these studies the author developed a real-time macroscopic and microscopic imaging system able to apply commercially available gamma- and beta-ray emitters. The real-time movement of the elements is now possible by using 14C, 18F, 22Na, 28Mg, 32P, 33P, 35S, 42K, 45Ca, 48V, 54Mn, 55Fe, 59Fe, 65Zn, 86Rb, 109Cd, and 137Cs. The imaging methods was applied to study the effect of 137Cs following 3/11 Fukushima Daiichi nuclear plant accident, which has revealed the movements of radiocesium in the contaminated sites.
