With the objective to collate the enormous amount of information on magnetic susceptibility parameters of a very large number of a variety of skeletons and present it in a form that can readily be retrieved and used, a new pattern is being introduced with the present volume keeping in view that now a majority of research groups look at the scientific data electronically.All the magnetic properties of each individual substance are listed as a single document which is self explainable and allowing search in respect of substance name, synonyms, common vocabulary, and even structure. It is hoped that the new pattern will facilitate greater accessibility of magnetic data.
Volume 43 of Group III deals with crystallographic data of both intermetallic and classical inorganic compounds, thus forming an update of the former Landolt-Börnstein volumes III/6 (Structure Data of Elements and Intermetallic Phases) and III/7 (Crystal Structure Data of Inorganic Compounds). It does not include compounds that contain C-H bonds.Moreover, in contrast to the earlier edition the present volume presents the data in a different, more modern arrangement - known crystal structures are combined in groups according to their type of structure; each structure type is therefore represented by a complete set of crystallographic data holding for all isotypic structures, with the data comprising space group, cell parameters and atom coordinates. Remarks, descriptions and figures are provided where necessary.The present subvolume A 1, which utilizes the databases TYPIX and Pauling File, forms the first contribution to volume 43, which is going to be published in a series of subvolumes.
The volume Observed Global Climate comprises a set of climate budget quantities, relevant for atmosphere and ocean (the climate fluids) as well as for land and ice (the climate solids). Examples for budget quantities are temperature, salinity, wind, rain, radiation. They are displayed in standardised form for all climate subsystems. The data are arranged around the budget principle which is basic for the entire climate system. The book demonstrates that budgeting is not only a useful principle but also that budget-thinking has practically become state of the art in modern quantitative climatology. Examples include the global water budget (consistency of the components better than 10%) and the global energy budget (consistency better than 5%).The data are based on direct observations but have been subject to data assimilation. They are presented in gridded form and in form of maps and sections. The DVD carries the data, the original articles, figures in original colours, plus additional material like animations of the most important climate parameters and selected non-standard quantities. The gridded fields can be loaded by the user from the DVD into the personal computer.
Biological processes are driven by complex systems of functionally interacting signaling molecules. Thus, understanding signaling molecules is essential to explain normal or pathological biological phenomena. A large body of clinical and experimental data has been accumulated over these years, albeit in fragmented state. Hence, systems biological approaches concomitant with the understanding of each molecule are ideal to delineate signaling networks/pathways involved in the biologically important processes. The control of these signaling pathways will enrich our healthier life.Currently, there are more than 30,000 genes in human genome. However, not all the proteins encoded by these genes work equally in order to maintain homeostasis. Understanding the important signaling molecules as completely as possible will significantly improve our research-based teaching and scientific capabilities.This encyclopedia presents 350 biologically important signaling molecules and the content is built on the core concepts of their functions along with early findings written by some of the world''s foremost experts. The molecules are described by recognized leaders in each molecule. The interactions of these single molecules in signal transduction networks will also be explored. This encyclopedia marks a new era in overview of current cellular signaling molecules for the specialist and the interested non-specialist alikeDuring past years, there were multiple databases to gather this information briefly and very partially. Amidst the excitement of these findings, one of the great scientific tasks of the coming century is to bring all the useful information into a place. Such an approach is arduous but at the end will infuse the lacunas and considerably be a streamline in the understanding of vibrant signaling networks. Based on this easy-approach, we can build up more complicated biological systems.
Nuclear resonance parameters for levels created in reactions with incident protons and a-particles, as well as other light charged particles such as deuterons, tritons, and He-3 nuclei, are of great interest for nuclear spectroscopy, astrophysical models, thermonuclear calculations and other applications. In the Landolt-Börnstein volume I/19A the parameters have now been compiled. No systematic compilation for such data has been performed so far. A large part of the experimental data has been produced during the last 10 years. The compilation was prepared by eminent experts in the fields. One of the characteristics of Landolt-Börnstein is that data are evaluated before they are accepted for compilation. The idea is to present ''best values'' which can be used with confidence by non-experts. Preparing such best values also implied making corrections necessary because of different energy calibrations in various publications. Subvolume I/19A2 contains the data for nuclei with Z ranging from 19 to 83. In view of the large amount of data available some of the information is given on the CD ROM only. The data for nuclei with Z up to 18 has been published in Subvolume I/19A1. Parameters for nuclear levels produced in reactions with incident neutrons were previously published by Landolt-Börnstein in volumes I/16B and I/16C.
Volume I/22B is the second of two volumes dedicated to nuclear binding energies and atomic masses of all nuclei. Related properties like the separation energies of single nucleons, or groups of nucleons, Q-values of alpha and beta nuclear reactions, and parameters of the residual interaction between nucleons, are considered as well. Also the experimental values are compared to the results of various model calculations. This comparison of experimental and theoretical results may help in the further development of nuclear theory. The data presented will also be of great significance for astrophysics and the understanding of the production of elements in the early universe. The present compilation was prepared by two eminent experts in the field. One of the characteristics of Landolt-Börnstein is that data are evaluated before they are accepted for compilation. The idea is to present ''best values'' which can be used with confidence by non-experts. Volume I/22B contains the data for 1194 nuclei with Z ranging from 55 to 100. In view of the large amount of data available some of the information is given online only at www.springerlink.com (DOI: 10.1007/978-3-540-70609-0). Parameters for nuclear levels of many nuclei were previously published by Landolt-Börnstein in Volumes I/16, I/18, and I/19.
Volume I/26A is presenting newly published neutron resonance parameters for nuclei ranging from Hydrogen (Z=1) to Californium (Z=98) supplementing data published in previous Landolt-Börnstein volumes. The quality and precision of the data have been improved considerably. The data were compiled by two eminent experts in the field who undertook great efforts to compare data from different laboratories to present best values.Accurate neutron resonance parameters embody an important contribution to improve nuclear data for a variety of applications such as the design and safe operation of nuclear reactors, the development of advanced energy production technologies, transmutation of nuclear waste, and nuclear astrophysics.Additionally, one chapter is dedicated to the characterization of materials and objects by neutron resonance spectroscopy. Transmission and capture analysis using time-of-flight measurements are described in detail. Applications ranging from archeology, astrophysics, investigation of nuclear material, thermometry or resonance imaging for the study of molten nuclear fuel are presented. Another chapter presents empirical evidence for regularities in the systematics of level spacing.In view of the large amount of data the parameters for only the most important resonances are given in the printed version, whereas the data for all resonances are available online on www.springermaterials.com. Neutron resonance parameters of many nuclei were previously published by Landolt-Börnstein in Volumes I/16B, I/16C, and I/24.
The porphyrins are an important class of naturally occurring macrocyclic compounds that play a very important role in the metabolism of living organisms. They have a universal biological distribution and were involved in the oldest metabolic phenomena on earth. Without porphyrins and their relative compounds, life as we know it would be impossible and therefore the knowledge of these systems and their excited states is essential in understanding a wide variety of biological processes, including oxygen binding, electron transfer, catalysis, and the initial photochemical step in photosynthesis. The objective of this volume is to present a full and critical spectral data coverage of the entire major fields relating to porphyrin isomers and expanded porphyrins, their precursors, catabolic derivatives, and related systems electronically.
With the development of modern instruments and theories, a considerable amount of spectroscopic informationis being permanently collected on molecules. The infrared, in particular, is seeing extraordinary activities. Using Fourier transform interferometers and infrared lasers, accurate data are measured often with extreme sensitivity. These data are also analyzed and precise molecular parameters determined. Volume II/20, "Molecular Constants Mostly from Infrared Spectroscopy", is a recent Landolt-Börnstein publication series bringing together these results. It is made up of several volumes (A, B, C, D) with comprehensive compilation of critically evaluated molecular constants of diatomic (A), linear triatomic (B); nonlinear triatomic (C), and other polyatomic (D) molecules. Subvolume II/20C1 is devoted to H2O.

Competent experts provide a summary of the enormous progress achieved in the development of new detection methods of charged and neutral particles, and photons. These achievements were initiated by the advent of new particle colliders, e.g., the LHC at CERN, but also by non-accelerator experiments. Part 1 of Subvolume B reviews the interaction of particle radiation with matter, and describes particle detectors, like, e.g., scintillation, gaseous, solid state, time-of-flight, Cerenkov, transition radiation, and neutrino detectors. Calorimetry and nuclear emulsions are considered as well. Finally, signal processing for particle detectors, data treatment and analysis methods (including detector simulation, high-level data selection, pattern recognition, distributed computing, and statistical issues) are addressed.

Graphical representations, including the calculated phase diagram for each system, are also possible. Information on more comprehensive software, allowing complex equilibrium calculations involving both pure substances and solution phases of different types (e.g. slags, salt systems, aqueous solutions, etc.), can be obtained from SGTE members. A list of the SGTE membership is presented in the cover pages of this volume.
Physics Of Solid Surfaces: Subvolume B
The Landolt-Börnstein volume II/30 contains data on the geometric parameters (internuclear distances, bond angles, dihedral angles of internal rotation, etc.) of free polyatomic molecules including free radicals and molecular ions. This volume is made of two subvolumes, each containing the geometric parameters determined in the gas phase either by an analysis of the rotational constants (and sometimes the vibrational constants) obtained from microwave, infrared, Raman, electronic, and photoelectron spectroscopy or by an analysis of electron diffraction intensities. All data obtained by these methods have been critically evaluated and compiled. The data are presented separately for each molecule, together with original references and computer-drawn figure(s). In this second subvolume, II/30B, the structures of molecules with three or more than three carbon atoms are listed. Subvolume II/30A covers inorganic molecules and molecules containing one or two carbon atoms.

1 Introduction Data extract from Landolt-Börnstein IV/17: Static Dielectric Constants of Pure Liquids and Binary Liquid Mixtures 1. 1 Selection of data This supplement updates Landolt-Börnstein''s New Series Group IV (Physical Chemistry) Volume 6, Static Dielectric Constants of Pure Liquids and Binary Liquid Mixtures, published in the year 1991 [1991WOH1]. The update provides experimental data published in the years 1991 to 2006. The ?nal date for including data was December, 31st, 2006. Specialization and selection of data for this new update follows the intentions of the original volume. The focus is on non-electrolyte systems, and only data for pure liquids and binary liquid mixtures at normal pr- sure (or in some single cases at the saturation vapor pressure) were taken into account for this volume. No data at higher pressures were collected, no data for the gaseous state, and no data for dielectric relaxation processes at higher frequencies have been included. For mixtures, this data collection is restricted to binary liquid mixtures, i. e. no ternary systems and also no solutions of any solids, salts, electrolytes, polymers are included here. At least, also molten metals and metallic alloys, molten salts, molten glasses and other hi- temperature melts were not taken into account. As the amount of data collected between 1991 and 2006 exceeds the available space for printing by far, the volume has an electronic version containing additional data which is available on www. landolt-boernstein.
