What would you do if you lost everything at age thirteen? When this happens to David, he has to a make a choice to be bitter and let life's situation bring him down or learn and grow. To make matters worse, he is also saddled with being responsible for his stubborn little brother, Sam. The real adventure begins when they are moved to a Texas orphanage called Boy's Ranch. There they meet the people (both good and bad) who will help shape their lives. David meets his best friends, the love of his life, and his worst nightmares while trying to establish a new family. Before he knows it, he becomes the head of a family of broken kids who have been thrown away. They band together, learn to trust, have crazy escapades, and find hope and faith to help them on their way. Just when it seems that everything is coming together, it all falls apart.
For better or for worse, in recent times the rapid growth of international economic exchange has changed our lives. But when did this process of globalization begin, and what effects did it have on economies and societies? Pim de Zwart and Jan Luiten van Zanden argue that the networks of trade established after the voyages of Columbus and Da Gama of the late fifteenth century had transformative effects inaugurating the first era of globalization. The global flows of ships, people, money and commodities between 1500 and 1800 were substantial, and the re-alignment of production and distribution resulting from these connections had important consequences for demography, well-being, state formation and the long-term economic growth prospects of the societies involved in the newly created global economy. Whether early globalization had benign or malignant effects differed by region, but the world economy as we now know it originated in these changes in the early modern period.
Lubricants are essential in engineering, however more sustainable formulations are needed to avoid adverse effects on the ecosystem. Bio-based lubricant formulations present a promising solution. Biolubricants: Science and technology is a comprehensive, interdisciplinary and timely review of this important subject. Initial chapters address the principles of lubrication, before systematically reviewing fossil and bio-based feedstock resources for biodegradable lubricants. Further chapters describe catalytic, (bio) chemical functionalisation processes for transformation of feedstocks into commercial products, product development, relevant legislation, life cycle assessment, major product groups and specific performance criteria in all major applications. Final chapters consider markets for biolubricants, issues to consider when selecting and using a lubricant, lubricant disposal and future trends. With its distinguished authors, Biolubricants: Science and technology is a comprehensive reference for an industrial audience of oil formulators and lubrication engineers, as well as researchers and academics with an interest in the subject. It provides an essential overview of scientific and technological developments enabling the cost-effective improvement of biolubricants, something that is crucial for the green future of the lubricant industry.

Contains an outline of the principles and characteristics of relevant instrumental techniques, provides an overview of various aspects of direct additive analysis by focusing on an array of applications in R ampD, production, quality control, and technical service.
This industrially relevant resource covers all established and emerging analytical methods for the deformulation of polymeric materials, with emphasis on the non-polymeric components. Each technique is evaluated on its technical and industrial merits. Emphasis is on understanding (principles and characteristics) and industrial applicability. Extensively illustrated throughout with over 200 figures, 400 tables, and 3,000 references.
Biodiesel production is a rapidly advancing field worldwide, with biodiesel fuel increasingly being used in compression ignition (diesel) engines. Biodiesel has been extensively studied and utilised in developed countries, and it is increasingly being introduced in developing countries, especially in regions with high potential for sustainable biodiesel production. Initial sections systematically review feedstock resources and vegetable oil formulations, including the economics of vegetable oil conversion to diesel fuel, with additional coverage of emerging energy crops for biodiesel production. Further sections review the transesterification process, including chemical (catalysis) and biochemical (biocatalysis) processes, with extended coverage of industrial process technology and control methods, and standards for biodiesel fuel quality assurance. Final chapters cover the sustainability, performance and environmental issues of biodiesel production, as well as routes to improve glycerol by-product usage and the development of next-generation products. Biodiesel science and technology: From soil to oil provides a comprehensive reference to fuel engineers, researchers and academics on the technological developments involved in improving biodiesel quality and production capacity that are crucial to the future of the industry. Evaluates biodiesel as a renewable energy source and documents global biodiesel development The outlook for biodiesel science and technology is presented exploring the challenges faced by the global diesel industry Reviews feedstock resources and vegetable oil formation including emerging crops and the agronomic potential of underexploited oil crops
