DOWNLOAD EBOOKIn Land Is the Cry! Susanne Starling tells the fascinating story of Warren Angus Ferris, Rocky Mountain fur trader, surveyor, farmer, and "Father of Dallas County". Ferris was one of the two founders of Dallas, along with land speculator William P. King. But Ferris merited fame even before he came to Texas in 1837, for his remarkable story encompasses three arenas: the Niagara frontier of western New York, the fur-trading country of the Rocky Mountains, and frontier northeast Texas during the years of the Republic. Ferris served as the official surveyor for Nacogdoches County, which then included much of northeast Texas. Warren Ferris spent another thirty-five years of his eventful life in Texas.

DOWNLOAD EBOOKLearning to Think Spatially examines how spatial thinking might be incorporated into existing standards-based instruction across the school curriculum. Spatial thinking must be recognized as a fundamental part of Kâ€"12 education and as an integrator and a facilitator for problem solving across the curriculum. With advances in computing technologies and the increasing availability of geospatial data, spatial thinking will play a significant role in the information-based economy of the twenty-first century. Using appropriately designed support systems tailored to the Kâ€"12 context, spatial thinking can be taught formally to all students. A geographic information system (GIS) offers one example of a high-technology support system that can enable students and teachers to practice and apply spatial thinking in many areas of the curriculum.

DOWNLOAD EBOOKCities across the globe are looking to develop affordable, environmentally friendly, and socially responsible transportation solutions that can meet the accessibility needs of expanding metropolitan populations and support future economic and urban development. When appropriately planned and properly implemented as part of a larger public transportation network, urban rail systems can provide rapid mobility and vital access to city centers from surrounding districts. High-performing urban rail services, when carefully approached as development projects, can help enhance quality of life by giving citizens access to employment opportunities, essential services, urban amenities, and neighboring communities. The purpose of this Handbook is to synthesize and disseminate knowledge to inform the planning, implementation, and operations of urban rail projects with a view towards: -- Emphasizing the need for early studies and project planning; -- Making projects more sustainable (economically, socially, and environmentally); -- Improving socioeconomic returns and access to opportunities for users; -- Maximizing the value of private participation, where appropriate; and -- Building capacity within project implementing and managing institutions This Handbook provides experiential advice to tackle the technical, institutional, and financial challenges faced by decision makers considering urban rail projects. It brings together the expertise of World Bank staff and the input of numerous specialists to synthesize international 'good practices' and recommendations that are independent of commercial, financial political, or other interests. The material presented is intended as an honest-broker guide to maximize the impact and manage the challenges of urban rail systems in cities in both developed and developing countries. Rather than identify a single approach, this Handbook acknowledges the complexities and context necessary when approaching an urban rail development by helping to prepare decision makers to ask the right questions, consider the key issues, perform the necessary studies, apply adequate tools, and learn from international good practice all at the right time in the project development process.

DOWNLOAD EBOOKThis collection presents, for the first time, a much-needed synthesis of the major research themes and findings that characterize the Woodland Period in the southeastern United States. The Woodland Period (ca. 1200 B.C. to A.D. 1000) has been the subject of a great deal of archaeological research over the past 25 years. Researchers have learned that in this approximately 2000-year era the peoples of the Southeast experienced increasing sedentism, population growth, and organizational complexity. At the beginning of the period, people are assumed to have been living in small groups, loosely bound by collective burial rituals. But by the first millennium A.D., some parts of the region had densely packed civic ceremonial centers ruled by hereditary elites. Maize was now the primary food crop. Perhaps most importantly, the ancient animal-focused and hunting-based religion and cosmology were being replaced by solar and warfare iconography, consistent with societies dependent on agriculture, and whose elites were increasingly in competition with one another. This volume synthesizes the research on what happened during this era and how these changes came about while analyzing the period's archaeological record. In gathering the latest research available on the Woodland Period, the editors have included contributions from the full range of specialists working in the field, highlighted major themes, and directed readers to the proper primary sources. Of interest to archaeologists and anthropologists, both professional and amateur, this will be a valuable reference work essential to understanding the Woodland Period in the Southeast.

DOWNLOAD EBOOKThis publication presents cleaning and etching solutions, their applications, and results on inorganic materials. It is a comprehensive collection of etching and cleaning solutions in a single source. Chemical formulas are presented in one of three standard formats - general, electrolytic or ionized gas formats - to insure inclusion of all necessary operational data as shown in references that accompany each numbered formula. The book describes other applications of specific solutions, including their use on other metals or metallic compounds. Physical properties, association of natural and man-made minerals, and materials are shown in relationship to crystal structure, special processing techniques and solid state devices and assemblies fabricated. This publication also presents a number of organic materials which are widely used in handling and general processing...waxes, plastics, and lacquers for example. It is useful to individuals involved in study, development, and processing of metals and metallic compounds. It is invaluable for readers from the college level to industrial R & D and full-scale device fabrication, testing and sales. Scientific disciplines, work areas and individuals with great interest include: chemistry, physics, metallurgy, geology, solid state, ceramic and glass, research libraries, individuals dealing with chemical processing of inorganic materials, societies and schools.

DOWNLOAD EBOOKM. C. Roco and W.S. Bainbridge In the early decades of the 21st century, concentrated efforts can unify science based on the unity of nature, thereby advancing the combination of nanotechnology, biotechnology, information technology, and new technologies based in cognitive science. With proper attention to ethical issues and societal needs, converging in human abilities, societal technologies could achieve a tremendous improvement outcomes, the nation's productivity, and the quality of life. This is a broad, cross cutting, emerging and timely opportunity of interest to individuals, society and humanity in the long term. The phrase "convergent technologies" refers to the synergistic combination of four major "NBIC" (nano-bio-info-cogno) provinces of science and technology, each of which is currently progressing at a rapid rate: (a) nanoscience and nanotechnology; (b) biotechnology and biomedicine, including genetic engineering; (c) information technology, including advanced computing and communications; (d) cognitive science, including cognitive neuroscience. Timely and Broad Opportunity. Convergence of diverse technologies is based on material unity at the nanoscale and on technology integration from that scale.
