Download or read book Indigenous Food Systems written by Priscilla Settee and published by Canadian Scholars. This book was released on 2020-01-31 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Indigenous Food Systems addresses the disproportionate levels of food-related health disparities among First Nations, Métis, and Inuit people in Canada, seeking solutions to food insecurity and promoting well-being for current and future generations of Indigenous people. Through research and case studies, Indigenous and non-Indigenous food scholars and community practitioners explore salient features, practices, and contemporary challenges of Indigenous food systems across Canada. Highlighting Indigenous communities’ voices, the contributing authors document collaborative initiatives between Indigenous communities, organizations, and non-Indigenous allies to counteract the colonial and ecologically destructive monopolization of food systems. This timely and engaging collection celebrates strategies to revitalize Indigenous food systems, such as achieving cultural resurgence and food sovereignty; sharing and mobilizing diverse knowledges and voices; and reviewing and reformulating existing policies, research, and programs to improve the health, well-being, and food security of Indigenous and Canadian populations. Indigenous Food Systems is a critical resource for students in Indigenous studies, public health, anthropology, and the social sciences as well as a vital reader for policymakers, researchers, and community practitioners.

Download or read book Structural Control of Mineral Deposits written by Alain Chauvet and published by MDPI. This book was released on 2019-04-16 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Structural Control” remains a crucial point that frequently lacks in any scientific and/or economic analysis of ore deposits, whatever their type and class. The case of lode deposits is exemplary, although also other deposits, like breccia pipe, stockwerk, massive sulphides, skarn, etc., can, surprisingly, be concerned. Several concepts like the gold-bearing shear zone have not proven valid during the last few decades in terms of our understanding of gold deposit and have been totally abandoned. Additionally, the relationships between magmatism, regional tectonic context, and mineralization remain uncertain and have been debated in several recent publications. This demonstrates that this issue is still relevant, and its solution may help in the distinction between intrusion-related and orogenic deposits. In this Special Issue, we particularly invite any case study of mineral deposits, in which it has been demonstrated that structural geology may have a significant role in the establishment of the deposit model of formation and/or on exploration and exploitation programs. Examples in which the structural model diverges from those described in the classical literature are particularly welcomed, including studies in which relationships with magmatism can be suspected and/or demonstrated. Indeed, all cases that illustrate concepts that differ from the classic ones and from theoretical models may represent significant contributions to this volume.
Download or read book Methods in Human Cytogenetics written by E. Passarge and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume was originally intended to be an English translation of the book MetllOden in der medizinischen Cytogenetik, published in 1970. Just about then, however, a number of new techniques were introduced in human cytogenetics and soon acquired the utmost importance, parti cularly in clinical diagnosis, so that the English edition had to be con siderably enlarged. As a result, there are now twelve chapters instead of eight, and two additional authors have been called upon, Dr. KRONE and Dr. SCHNEDL. In addition to the up-to-date presentation of con ventional methods of cell culture and techniques for the preparation and identification of human chromosomes, this text covers the various tech niques of producing banding patterns and applying them in chromo some identification. Further, it deals with the culture of amniotic fluid cells and gives instructions for handling tissue-culture cells for bio chemical analysis; it thus meets the ever-increasing requirements of a modern cell-culture laboratory. To paraphrase the aims of this book, we quote part of the preface to the German edition: "It was intended to collect the various methods so as to make them accessible for laboratory use. Furthermore, it is hoped that the reader faced with current research problems will be stimulated to modify and supplement the techniques described, instead of merely applying them automatically. In a rapidly developing field, some methods are still preliminary, and no final presentation seems possible.
Download or read book Biology of Hevea Rubber written by P.M. Priyadarshan and published by Springer. This book was released on 2017-06-09 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the second edition of this book, the origin, upkeep and latex harvest from the Hevea rubber tree are dealt with succinctly. New chapters have been included on Propagation Systems and Genetic Resources. The importance of Heterozygosis and Breeding is a new theme for the section on Breeding. A new chapter on Genomics and Molecular Breeding that focuses on the latest advancements on gene mapping, marker assisted selection and stimulation has been added. Lastly, ‘textboxes’ that highlight points and topics of significant interest are included in the new addition. Natural rubber has been an essential commodity not only for the tire industry but also for more than 50,000 products that holds elasticity as an attribute. The prime source of natural rubber worldwide is Hevea brasiliensis. Hevea rubber tree is an excellent example of how a soil-tree-atmosphere system can work in tandem. The retrieval of rubber through ‘injuring’ the tree on alternate days or once in three days or once in seven days, is indeed a unique arrangement followed universally that ensures income to the planter almost throughout the year. Every molecule of rubber is the end result of meticulous biochemical changes. Therefore the biology of Hevea rubber tree itself is a subject that aggregates science and technology for the realization of its industrial utility.
Download or read book Directions in Educational Planning written by Mark Bray and published by United Nations Education, Scientific & Cultural Organization. This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nature of educational planning has evolved significantly during the past few decades. For many years, it generally relied on grand models focusing on macro-planning. Today, the field is increasingly defined by decentralized approaches, non-government funding, and cross-national forces in the context of globalization. IIEP has played a lead role in contributing to conceptual issues, developing methodologies, and facilitating capacity development. In 2008, the Institute organized a symposium to discuss the changing context and content of educational planning, reflecting on continuities and changes in the past and looking ahead to the future. This publication is based on selected papers presented at the symposium.

Download or read book Adhesion Between Polymers and Concrete Adh sion Entre Polym res Et B ton written by H. R. Sasse and published by Springer. This book was released on 1986 with total page 792 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.
Download or read book Handbook of Multilingualism and Multiculturalism written by Geneviève Zarate and published by Archives contemporaines. This book was released on 2011 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Built around the concept of linguistic and cultural plurality, this book defines language as an instrument of action and symbolic power. Plurality is conceived here as : a complex array of voices, perspectives and approaches that seeks to preserve the complexity of the multilingual and multicultural enterprise, including language learning and teaching ; a coherent system of relationships among various languages, research traditions and research sites that informs qualitative methods of inquiry into multilingualism and its uses in everyday life ; a view of language as structured sociohistorical object, observable from several simultaneous spatiotemporal standpoints, such as that of daily interactions or that which sustains the symbolic power of institutions. This book is addressed to teacher trainers, young researchers, decision makers, teachers concerned with the role of languages in the evolution of societies and educational systems. It aims to elicit discussion by articulating practices, field observations and analyses based on a multidisciplinary conceptual framework.
Download or read book Lipids and Lipid Polymers in Higher Plants written by M. Tevini and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains a number of papers dealing with the main topics of a Symposium on "Lipids and Lipid Polymers in Higher Plants", held in July 1976 at the Botanical Institute of the University of Karlsruhe. The symposium was organized by Professors E. Heinz, H.K. Lichtenthaler, H.K. Mangold, and M. Tevini. The sponsorship by the Deutsche Forschungsgemeinschaft and the Erwin-Riesch-Stiftung is gratefully acknowledged. The intention of the Symposium was to bring together in one place scientists working in very different fields of plant lipids, such as fatty acids, glycolipids, phospholipids, prenyllipids, sterols, and lipid polymers. The emphasis was placed on biosynthesis, distribution, function, and physiology of the various higher plant lipids and their role in biomembranes and epidermal cell walls. By combining the major contributions in this book, we hope to give all plant scientists access to the recent developments in biochemistry and physiology of plant lipid metabolism. The editors are very grateful to the contributors, who have taken great care to present up-to-date reviews. Karlsruhe, May 1977 M. TEVINI H.K. LICHTENTHALER Contents Section 1.

Download or read book Glyoxal written by J. Kielhorn and published by WHO. This book was released on 2004 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication, part of a series from the International Programme on Chemical Safety, evaluates the risk to human health and the environment posed by exposures to glyoxal. Glyoxal is used as a chemical intermediate in the production of pharmaceuticals and dyestuffs, as a cross-linking agent in the production of a range of different polymers, as a biocide, and as a disinfecting agent. It is frequently detected in fermented food and beverages since it is produced by microbial activity as well as non-enzymatic autoxidation of oil or browning reactions of saccharides.
Download or read book Plant Diseases and Food Security in the 21st Century written by Peter Scott and published by Springer Nature. This book was released on 2021-05-22 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of the global population of more than 7 billion people, some 800 million do not have enough to eat today. By 2050, the population is expected to exceed 9 billion. It has been estimated that some 15% of food production is lost to plant diseases; in developing countries losses may be much higher. Historically, plant diseases have had catastrophic impact on food production. For example: potato blight caused the Irish famine in 1845; brown spot of rice caused the Great Bengal Famine of 1943; southern corn leaf blight caused a devastating epidemic on the US corn crop in 1970. Food security is threatened by an ongoing sequence of plant diseases, some persistent for decades or centuries, others more opportunistic. Wheat blast and banana xanthomonas wilt are two contrasting examples of many that currently threaten food production. Other emerging diseases will follow. The proposed title aims to provide a synthesis of expert knowledge to address this central challenge to food security for the 21st century.
