In recent years it has become apparent that knowing the average atomic structure of materials is insufficient to understand their properties. Diffuse scattering in addition to the Bragg scattering holds the key to learning about defects in materials, the topic of many recent books. What has been missing is a detailed step-by-step guide how to simulate disordered materials. The DISCUS cook book fills this need covering simple topics such as building a computer crystal to complex topic such as domain structures, stacking faults or using advanced refinement techniques to adjust parameters on a disordered model. The book contains a CDROM with all files needed to recreate every example given using the program DISCUS. The reader is free to follow the principles behind simulating disordered materials or to get down into the details and run or modify the given examples.
Diffuse X-ray scattering is a rich (virtually untapped) source of local structural information over and above that obtained by conventional crystallography. The book aims to show how computer simulation of a model crystal provides a general method by which diffuse scattering of all kinds and from all types of materials can be interpreted and analysed.
This beautifully illustrated volume explores the richness of the J. Paul Getty Museum's holdings in German and Central European manuscripts from the ninth to the eighteenth century. This book showcases full-color reproductions of masterpieces from such works as Carolingian manuscripts of the ninth century; several sumptuously illuminated Ottonian texts from the late tenth and early eleventh centuries; two of the most celebrated examples of Romanesque illumination: the Helmarshausen Gospel book from the 1120s and the Stammheim Missal, made around 1170 for Saint Michael's monastery in Hildesheim; The Life of the Blessed Hedwig from 1353, and the only known illuminations by the Cologne painter called the Master of Saint Veronica, ca. 1400. It also illustrates many richly colored illuminations from such manuscripts as a luxury psalter made in Würzburg, dating from the mid-thirteenth century; a copy of Rudolf von Ems's Weltchronik, produced in the early fifteenth century; and chivalric and dynastic manuscripts from the sixteenth to the eighteenth centuries.
Volume Three of the definitive edition of Thomas Jefferson's papers from the end of his presidency until his death presents 567 documents covering the period from 12 August 1810 to 17 June 1811. Jefferson is now firmly ensconced in retirement at Monticello and Poplar Forest. He is not free from legal and political concerns, however, with the controversy over the 1807 federal seizure of the Batture Sainte Marie at New Orleans looming particularly large. Jefferson prepares for his defense against Edward Livingston's lawsuit by corresponding at length with his counsel and involved public officials, and seeking out documents and legal authorities to vindicate himself. He also seeks to end Philadelphia journalist William Duane's growing estrangement from mainstream Republican politics, lobbies for the appointment of a committed Republican to fill a vacancy on the Supreme Court, and argues with the Rivanna Company over its proposed encroachments on his property. Other highlights are Jefferson's draft constitution for an agricultural society, his astronomical calculations, his notes on plantings at Poplar Forest, and his estimate of the cost of shipping flour. Documents on slaves and slavery include discussions of schemes for colonizing freed slaves in Africa, information on the medical condition of some of Jefferson's slaves, and an account of a visit to Monticello with a distinctly unflattering portrayal of the ex-president's standing in the community and his relations with his slaves.
Small angle solution scattering (SAS) is increasingly being applied to biological problems. It is a complementary technique that, when applied in appropriate circumstances with carefully structured questions, can provide unique information not available from other techniques. While small angle solution scattering has been around for some time, a confluence of recent developments has dramatically enhanced its power. Intense third generation X-ray sources, low noise detectors, development of new algorithms and the computational power to take advantage of these have all matured, and use of free-electron x-ray laser sources is on the horizon. Whole new classes of experiments and analyses have been created as a result. These include the generation of molecular envelopes, the ability to do time-resolved studies, and the ability to account for structural changes using modelling based on the SAS data. The technical improvements have also reduced the amount of time and material needed to carry out an experiment. Beamtime at synchrotron sources is in demand, workshops on the subject are popular and researchers adopting the technique as part of their repertoire are growing. With these in mind, this book was written to guide structural biologists who may wish to adopt the technique, understand its strengths and weaknesses or just have a general interest in its potential.
