When the first edition of this book was published in 1957, the art of making a tipi was almost lost, even among American Indians. Since that time a tremendous resurgence of interest in the Indian way of life has occurred, resurgence due in part, at least, to the Laubins' life-long efforts at preservation and interpretation of Indian culture.As The Indian Tipi makes obvious, the American Indian is both a practical person and a natural artist. Indian inventions are commonly both serviceable and beautiful. Other tents are hard to pitch, hot in summer, cold in winter, poorly lighted, unventilated, easily blown down, and ugly to boot. The conical tipi of the Plains Indian has none of these faults. It can be pitched by one person. It is roomy, well ventilated at all times, cool in summer, well lighted, proof against high winds and heavy downpours, and, with its cheerful fire inside, snug in the severest winter weather. Moreover, its tilted cone, trim smoke flaps, and crown of poles, pres...
A complete account of the theory of the diffraction of x-rays by crystals with particular reference to the processes of determining the structures of protein molecules, this book is aimed primarily at structural biologists and biochemists but will also be valuable to those entering the field with a background in physical sciences or chemistry. It may be used at any post-school level, and develops from first principles all relevant mathematics, diffraction and wave
theory, assuming no mathematical knowledge beyond integral calculus.
The book covers a host of important topics in the area, including:
- The practical aspects of sample preparation and x-ray data collection, using both laboratory and synchrotron sources
- Data analysis at both theoretical and practical levels
- The important role played by the Patterson function in structure analysis by both molecular replacement and experimental phasing approaches
- Methods for improving the resulting electron density map
- The theoretical basis of methods used in refinement of protein crystal structures
- In-depth explanation of the crucial task of defining the binding sites of ligands and drug molecules
- The complementary roles of other diffraction methods which reveal further detail of great functional importance in a crystal structure.
