Santa Rita del Cobre: A Copper Mining Community in New Mexico (Mining the American West)
by Christopher J. Huggard Terrence M. HumbleAn account of the rise and fall of a mining town over two centuries, including photos: &“An excellent story of the people and their community.&” ―New Mexico Historical ReviewThe Spanish, Mexicans, and Americans, successively, mined copper for more than two hundred years in Santa Rita, New Mexico. Starting in 1799 after an Apache man led the Spanish to the native copper deposits, miners at the site followed industry developments in the nineteenth century to create a network of underground mines. In the early twentieth century these works became part of the Chino Copper Company&’s open-pit mining operations—operations that would overtake Santa Rita by 1970. In Santa Rita del Cobre, Christopher Huggard and Terrence Humble detail these developments with in-depth explanations of mining technology, and describe the effects on and consequences for the workers, the community, and the natural environment. Originally known as El Cobre, the mining-military camp of Santa Rita del Cobre ultimately became the company town of Santa Rita, which after World War II evolved into an independent community. From the town&’s beginnings to its demise, its mixed-heritage inhabitants from Mexico and the United States cultivated rich family, educational, religious, social, and labor traditions. Extensive archival photographs, many taken by officials of the Kennecott Copper Corporation, accompany the text, providing an important visual and historical record of a town swallowed up by the industry that created it.

Saproxylic Insects: Diversity, Ecology And Conservation (Zoological Monographs #1)
by Michael D. UlyshenThis volume offers extensive information on insect life in dying and dead wood. Written and reviewed by leading experts from around the world, the twenty-five chapters included here provide the most global coverage possible and specifically address less-studied taxa and topics. An overarching goal of this work is to unite literature that has become fragmented along taxonomic and geographic lines. A particular effort was made to recognize the dominant roles that social insects (e.g., termites, ants and passalid beetles) play in saproxylic assemblages in many parts of the world without overlooking the non-social members of these communities.The book is divided into four parts:· Part I “Diversity” includes chapters addressing the major orders of saproxylic insects (Coleoptera, Diptera, Hymenoptera, Hemiptera, Lepidoptera and Blattodea), broadly organized in decreasing order of estimated global saproxylic diversity. In addition to order-level treatments, some chapters in this part discuss groups of particular interest, including pollinators, hymenopteran parasitoids, ants, stag and passalid beetles, and wood-feeding termites.· Part II “Ecology” discusses insect-fungal and insect-insect interactions, nutritional ecology, dispersal, seasonality, and vertical stratification.· Part III “Conservation” focuses on the importance of primary forests for saproxylic insects, offers recommendations for conserving these organisms in managed forests, discusses the relationships between saproxylic insects and fire, and addresses the value of tree hollows and highly-decomposed wood for saproxylic insects. Utilization of non-native wood by saproxylic insects and the suitability of urban environments for these organisms are also covered.· Lastly, Part IV “Methodological Advancements” highlights molecular tools for assessing saproxylic diversity. The book offers an accessible and insightful resource for natural historians of all kinds and will especially appeal to entomologists, ecologists, conservationists and foresters.

Sarcopenia: Molecular, Cellular, and Nutritional Aspects
by Dominique Meynial-DenisSarcopenia: Molecular, Cellular, and Nutritional Aspects describes the progressive loss of skeletal muscle mass and strength, defined by Rosenberg in 1997 as a hallmark of aging and referred to as &“sarcopenia.&” As life expectancy continues to increase worldwide, sarcopenia has become a major public health issue. The condition worsens in the presence of chronic diseases accelerating its progression. Sarcopenia is not considered to be &“a process of normative aging&” but according to the International Classification of Disease, Tenth Revision, Clinical Modification (ICD-10-CM), as a disease. As sarcopenia is an ineluctable process, prevention and management are the only options to promote healthy aging; these actions should perhaps be taken during youth. <p><p>Included in this book: <li>Features essential information on sarcopenia, its current definition, and molecular and cellular aspects of this disease <li>Discusses the development of physical frailty, a complication of sarcopenia, and predicts its occurrence in the older population <li>Presents alterations in muscle protein turnover and mitochondrial dysfunction in the aging process <li>Provides data on the negative involvement of sarcopenia in certain chronic diseases <li>Describes presbyphagia or age-related changes in the swallowing mechanism in older people <li>Details possible strategies to combat muscle wasting in healthy older adults and their limits <p><p>This book features information collected from pioneers or experts on human aging from around the globe, including Europe, Brazil, Canada, Japan and the United States. It is a valuable source of information for nutritional scientists, medical doctors, sports scientists, food scientists, dietitians, students in these fields, and for anyone interested in nutrition. We hope this book provides a better understanding of sarcopenia which inevitably occurs with aging without weight loss. Moreover, this book will supply information outlining strategies to prevent or limit muscle wasting due to normal aging in order to promote successful aging.

Satellite-Based Mitigation and Adaptation Scenarios for Sea Level Rise in the Lower Niger Delta (Ihe Delft Phd Thesis Ser.)
by Zahrah Naankwat MusaThe Niger delta with its gentle slope and low elevation is extremely sensitive to effects of climate change. Its adaptive capacity is the second lowest in terms of socio-economic development in Nigeria. Quantitative studies on developing measures for coastal planning and management in the lower Niger delta have been limited by data availability and inaccessibility of parts of the delta. The use of satellite data can help bridge the data gap by providing ancillary data (imagery, elevation, altimetry etc.) that can be used to quantify the effects of SLR in the Niger delta. This thesis uses satellite data as the main source for hydrodynamic modelling and GIS analysis. Until recently such data might not have the accuracy and precision of directly measured data. However recent innovative approaches have enabled better exploitation of satellite data to overcome these limitations and produce adequate results to assess the impact of SLR on the Niger delta in an integrated way that will lead to practical recommendations for adaptation. Using projected global eustatic SLR values in combination with land subsidence, this thesis estimated SLR levels for the Niger delta and its effect on inundation areas and flood extent. The results indicate that the Niger delta is very vulnerable to inundation and that even minimal SLR will affect flooding in the lower Niger delta since the area continues to subside. A new coastal vulnerability index was developed in this thesis by evaluating physical, social and human influence indicators of exposure, susceptibility and resilience. The results show that parts of the Niger delta are highly vulnerable to SLR and need adequate mitigation/adaptation measures to protect them. It is recommended that sustainable local resilience practices already being used in parts of the Niger delta should be included in adaptation planning.

Satellite Equivalence Orbits: Analysis of Orbits Combining Different Motions (Space Technology Library #42)
by Ernst Friedrich JochimThis book presents the essential characteristics of the different satellite motions. Satellite motions can be classified as anomalistic, draconitic, tropical, Hansen-, Kepler-, meridional, Sun-synodical, Moon-synodical motion, depending on the relevant reference point. When two of these types of motions (in some cases even more than two) are coupled, satellite orbits are obtained, which are called equivalence orbits in this book. They share the special properties of the different coupled motions and are therefore of particular interest in the selection of special satellite orbits. In the book the author calculates mean equivalence orbits with secular perturbation formulas, as well as true equivalence orbits considering a complete orbit model including periodic motion effects. Some of the equivalence orbits can be determined unambiguously and with extremely high accuracy, they are stable in the long term. Others can only be found with low accuracy and reduced stability. The author investigates all possible combinations and the associated general equations of condition are derived in each case. Some well-known families of satellite orbits, such as the Sun-synchronous orbits, can be interpreted as mean equivalence orbits. The study of their stability is of great interest in orbit mechanics. Special applications and numerous numerical examples, graphical representations of all possible ranges of the Kepler elements, and detailed studies of the stability of particularly important equivalence orbits are carried out using the Brouwer orbit model as well as the modification by Eckstein. This lays the foundation for possible refinements using arbitrary extended orbital models and for possibly required orbital corrections. Numerous problems are to deepen the treated topics and/or to stimulate for further investigations. The book will be of interest to Astrodynamics and Aerospace Engineers as well as graduate students studying satellite orbits.
