With Golden Visions Bright Before Them
During the mid-nineteenth century, a quarter of a million travelers—men, women, and children—followed the “road across the plains” to gold rush California. This magnificent chronicle—the second installment of Will Bagley’s sweeping Overland West series—captures the danger, excitement, and heartbreak of America’s first great rush for riches and its enduring consequences. With narrative scope and detail unmatched by earlier histories, With Golden Visions Bright Before Them retells this classic American saga through the voices of the people whose eyewitness testimonies vividly evoke the most dramatic era of westward migration. Traditional histories of the overland roads paint th...
Free Flight Hypersonic Heat Transfer and Boundary Layer Transition Studies
Two HTV-1 Hypersonic Test Vehicles, Rounds A-40 and A-41, were flown at Holloman AFB in October 1959, with blunted and sharp 20 degree half angle nose cones, respectively. Round A-40 also incorporated nose cone incidence and a pitch disturber rocket. A maximum flight velociety of 5800 feet per second was attained, corresponding to a local shap cone Mach number and unit Reynolds number of 3.4 and 50 x 10(6) per foot respectively. Fligh dynamics data for the second stage of Round A-40 were obtained from analyses of the vector angle of attack history. The measured maximum trim angle of attack (1.5 degrees) agreed closely with the predicted trim based on an elastic structure and a nose cone inci...
Transition Reynolds Numbers of Separated Flows at Supersonic Speeds
Experimental research has been conducted on the effects of wall cooling, Mach number, and unit Reynolds number on the transition Reynolds number of cylindrical separated boudary layers on an ogive-cylinder model. Results were obtained from pressure and temperature measurements and shadowgraph observations. The maximum scope of measurements encompassed Mach numbers between 2.06 and 4.24, Reynolds numbers (based on length of separation) between 60,000 and 400,000, and ratios of wall temperatures to adiabatic wall temperature between 0.35 and 1.0.

Genetics, Genomics and Breeding of Stone Fruits
The stone fruits—including peaches, apricots, almonds, plums, and cherries—have been bred and grown for thousands of years and today are significant agricultural crops in many local economies worldwide. This volume presents a comprehensive commentary on classical genetics and breeding, molecular mapping and breeding of agronomic traits, and the cloning of genes of interest. It also explores recent advances on omics sciences including structural and functional genomics, proteomics, nd metabolomics. The book enumerates the whole genome sequencing of the model fruit plant peach and discusses bioinformatic strategies and tools for stone fruit research
Femtochemistry and Femtobiology
This book contains important contributions from top international scientists on the-state-of-the-art of femtochemistry and femtobiology at the beginning of the new millennium. It consists of reviews and papers on ultrafast dynamics in molecular science.The coverage of topics highlights several important features of molecular science from the viewpoint of structure (space domain) and dynamics (time domain). First of all, the book presents the latest developments, such as experimental techniques for understanding ultrafast processes in gas, condensed and complex systems, including biological molecules, surfaces and nanostructures. At the same time it stresses the different ways to control the rates and pathways of reactive events in chemistry and biology. Particular emphasis is given to biological processes as an area where femtodynamics is becoming very useful for resolving the structural dynamics from techniques such as electron diffraction, and X-ray and IR spectroscopy. Finally, the latest developments in quantum control (in both theory and experiment) and the experimental pulse-shaping techniques are described.
Molecular Marker Systems in Plant Breeding and Crop Improvement
Successful release of new and better crop varieties increasingly requires genomics and molecular biology. This volume presents basic information on plant molecular marker techniques from marker location up to gene cloning. The text includes a description of technical approaches in genome analysis such as comparison of marker systems, positional cloning, and array techniques in 19 crop plants. A special section focuses on converting this knowledge into general and specific breeding strategies, particularly in relation to biotic stress. Theory and practice of marker assisted selection for QTL, gene pyramiding and the future of MAS are summarized and discussed for maize, wheat, and soybean. Furthermore, approaches in silviculture on the examples of Fagus, Populus, Eucalyptus, Picea and Abies are presented. The volume ends with a comprehensive review of the patents relevant for using molecular markers and marker assisted selection.
