Book Synopsis Traditional Forest-Related Knowledge by : John A. Parrotta
Download or read book Traditional Forest-Related Knowledge written by John A. Parrotta and published by Springer Science & Business Media. This book was released on 2011-10-14 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exploring a topic of vital and ongoing importance, Traditional Forest Knowledge examines the history, current status and trends in the development and application of traditional forest knowledge by local and indigenous communities worldwide. It considers the interplay between traditional beliefs and practices and formal forest science and interrogates the often uneasy relationship between these different knowledge systems. The contents also highlight efforts to conserve and promote traditional forest management practices that balance the environmental, economic and social objectives of forest management. It places these efforts in the context of recent trends towards the devolution of forest management authority in many parts of the world. The book includes regional chapters covering North America, South America, Africa, Europe, Asia and the Australia-Pacific region. As well as relating the general factors mentioned above to these specific areas, these chapters cover issues of special regional significance, such as the importance of traditional knowledge and practices for food security, economic development and cultural identity. Other chapters examine topics ranging from key policy issues to the significant programs of regional and international organisations, and from research ethics and best practices for scientific study of traditional knowledge to the adaptation of traditional forest knowledge to climate change and globalisation.

This book was released on 2016-12-02 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2016 in the subject Engineering - Aerospace Technology, grade: -, , course: Aerospace Engineering, language: English, abstract: The primary aim of this research work is to examine the mechanical properties per weight density of novel core materials for use in sandwich panels. Composite lattice core sandwich structures with relative densities in the range of 3% to 35% were manufactured and tested under quasi-static compression loading conditions. Collapse strength, failure mechanisms and energy absorption characteristics of the lattice structures have been evaluated. Since these core material shapes are unique, research involved developing suitable manufacturing methods. The study started by looking at introducing simple through thickness lattice structure into PET foam cores. This was achieved by drilling the foam material, glass fibers were then inserted into the perforations. The panel was then infused with resin using the vacuum assisted resin transfer molding process. This was then extended to look at the possibility of removing the core by adopting a-lost mold manufacturing procedure that would leave a free-standing lattice structure. This involved inserting reinforcing fiber tows through holes in wax blocks. Following infusion with an epoxy resin and subsequent post curing, the preforms were heated to a temperature above that required to melt the wax, leaving well-defined lattice structures based on vertical, pyramidal, modified-pyramidal, octet configurations and others based on what are termed BCC, BCCz, FCC and F2BCC designs. Compression tests showed that the strength of individual struts and the corresponding cores increases with strut diameter and fiber volume fraction. Smaller diameter struts failed in buckling, whereas the larger diameter columns failed in a crushing mode involving high levels of energy absorption. Truss core structures with 4 mm diameter columns, based on 28% fiber volume fractions offered specific energy absorption values above 70 kJ/kg. Compression tests on the four lattice structures based on BCC, BCCz, FCC and F2BCC designs indicated that the F2BCC lattice offered the highest compression strength of approximately 12 MPa. Although, when normalized by relative density, the BCCz lattice structure out-performed the three remaining structures. The specific energy absorption values of the lattices were relatively high, ranging from 44 kJ/kg for the BCC lattice to 80 kJ/kg for the BCCz structure. Similarly, the specific compression strengths of some of the lattices have been shown to be superior to those of more traditional core materials. [...]

Book Synopsis Shepherds and Demons by : Hans Austnaberg
Download or read book Shepherds and Demons written by Hans Austnaberg and published by Peter Lang. This book was released on 2008 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Malagasy revival movement, which started in 1894 and operates within the structure of the historical churches, continues to have a profound impact on Protestant church life. This book focuses on exorcism as practised and understood by the so-called shepherds (lay, unsalaried, consecrated church workers) and defines «exorcism» as the expulsion of demons and prayer with the laying on of hands. This study, with Malagasy actors at its centre, argues that exorcism constitutes a synthesis between the biblical message and the traditional Malagasy culture. The shepherds, who vehemently oppose traditional religion, understand exorcism as a practice appropriate for people with a wide variety of problems, and they assert that the purpose of exorcism is to create a living faith in Jesus. The shepherds consider the battle with demons absolutely decisive because it concerns nothing less than salvation or condemnation.

Book Synopsis Rethinking Agriculture by : Timothy P Denham
Download or read book Rethinking Agriculture written by Timothy P Denham and published by Routledge. This book was released on 2016-07 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the need to study agriculture in different parts of the world on its “own terms” has long been recognized and re-affirmed, a tendency persists to evaluate agriculture across the globe using concepts, lines of evidence and methods derived from Eurasian research. However, researchers working in different regions are becoming increasingly aware of fundamental differences in the nature of, and methods employed to study, agriculture and plant exploitation practices in the past. Contributions to this volume rethink agriculture, whether in terms of existing regional chronologies, in terms of techniques employed, or in terms of the concepts that frame our interpretations. This volume highlights new archaeological and ethnoarchaeological research on early agriculture in understudied non-Eurasian regions, including Island Southeast Asia and the Pacific, the Americas and Africa, to present a more balanced view of the origins and development of agricultural practices around the globe.

Book excerpt: Two of the biggest challenges faced by human kind are the conservation of our environmental resources and the elimination of poverty. It is increasingly recognised that these problems are interlinked: the goods and services provided by natural resources are needed to improve well-being, whilst for conservation to succeed it must relate to the poor's needs. This is reflected by all major international policies focused on development or conservation, such as the Millennium Development Goals, and the Convention on Biological Diversity. BGCI believes that biodiversity conservation and poverty reduction must be linked if we are to succeed in either aim. This report highlights how botanic gardens across the world are involved in a variety of projects that use biodiversity to improve human well-being and is based upon an extensive literature survey, and a multilingual survey of BGCI's members. For the purposes of the report, BGCI has divided human well-being into four main areas: (1) improving healthcare, (2) improving nutrition, (3) alleviating financial poverty, and (4) improving community and social relations. The many case studies within the report illustrate how botanic gardens across the world are contributing to these aspects in many diverse ways. Many botanic gardens promote improved nutrition and health through their support of home gardens. Their horticultural skills and ability to propagate plant materials often prove invaluable in this respect. For example, Aburi Botanical Garden in Ghana has been improving local access to medicinal plants by empowering local communities to set up medicinal gardens. As well as establishing a model home garden, it gives a wide range of lectures, seminars, workshops and demonstrations, distributes manuals and provides seedlings to enable communities to set up their own nurseries and first aid gardens. There are many other ways that botanic gardens work for well-being, from developing and hosting horticultural therapy programmes, to educating children about healthy eating, and training disadvantaged minorities in useful skills. Around the world, botanic gardens are also helping local communities to develop income generating projects, such as the production of handicrafts, based on the sustainable use of plant resources. This report also illustrates how various activities of botanic gardens underpin their ability to conduct projects that address well-being issues. Education and research are core strengths that need to be supported and directed to ensure they can continue to link plant diversity with human well-being. For example, many gardens have strong emphasis on research relevant to the development of useful plants in use in agriculture and healthcare. A typical example is Kisantu Botanic Garden in the Democratic Republic of Congo, which conducted trials on the popular fruit mangosteen, to enable farmers to extend the shelf-life of the harvested fruit, and so reach a larger market. Other gardens, such as Botanic Garden "Fundación Xochitla" in Mexico, have focused on developing plants to be locally cultivated for use in the ornamentals market. Well-being projects are not limited to developing countries. In developed countries urban greening projects can make a significant contributions to improving neighbourhood environment and community relations. Sometimes well-being projects involve collaboration between gardens, linking well-resourced gardens with those in an early stage of development, or with little financial support, and in many cases the unique role of botanic gardens is complemented by partnerships and collaborations with non-botanic garden institutions, such as local healthcare clinics. Botanic gardens are clearly much more than just "pretty places". As this report illustrates, they are uniquely placed to use plant diversity to contribute to human well-being. Given the scale of the crisis facing our efforts for both conservation and development, BGCI believes that it is an ethical and practical imperative that botanic gardens are mobilised for this goal.

Book Synopsis Traces of Ancestry by : Martin Jones
Download or read book Traces of Ancestry written by Martin Jones and published by McDonald Institute Monographs. This book was released on 2004 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1987, Colin Renfrew's Archaeology and Language challenged many perceptions about how one language family spread across large parts of the world. In doing so he re-invigorated an important exchange between archaeologists and historical linguists. At precisely the same time, a quite separate field, human genetics, was making considerable steps forward in the elucidation of human ancestry. These three parallel lines of enquiry into genes, words, and things have, over the ensuing two decades, entirely transformed our perceptions of the human past. This volume brings together contributors to that transformation from around the world, to honour Colin Renfrew with a series of key papers. They include a number of impressive synthetic statements, as well as case studies at the frontiers of three different branches of research. They range from global accounts of human dispersal through to archaeological, genetic and linguistic studies, illustrating what has been achieved over the past two decades, and the most promising avenues of research for the future.
