This book was released on 2024-02-09 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Serpentinization is a reaction that involves the hydration of ferromagnesium minerals (e.g., olivine, pyroxenes), resulting in the production of hydrogen gas and reduced carbon compounds. This reaction also leads to the formation of mineral carbonates, and highly alkaline and reducing fluids. Microorganisms have adapted to such extremes and robust microbial communities were discovered at several locations, including the Mid-Atlantic Ridge, Mariana Forearc, the Cabeço de Vide Aquifer, the Cedars, the Coast Range Ophiolite Microbial Observatory, Hakuba Happo, the Samail ophiolite, the Voltri Massif, and the Zambales ophiolite. These locations represent a range of pressure and temperature conditions, demonstrating that serpentinization is a ubiquitous geologic process occurring at subduction zones, mid-ocean ridges, and passive margins. This process is also thought to have supported early life because of the availability of reduced products and the presence of geochemical disequilibria.

This book was released on 2016 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although serpentinization produces abiogenic organic compounds that can theoretically sustain microbial communities, it creates multiple challenges microbial communities must overcome, including alkaline environments (pH 10-12), highly reducing conditions and limited access to inorganic carbon. These adverse conditions make sustaining crucial physiological processes, such as maintaining a proton motive force and stabilizing RNA, difficult challenges for microbes to overcome. It is currently unknown what metabolic adaptations microbes have undergone to survive under these harsh conditions. In 2011, boreholes were drilled for core recovery and core fluid experimentation at two sites within the Coast Range Ophiolite Microbial Observatory (CROMO) near Lower Lake, CA in the McLaughlin Natural Reserve (Cardace et al., 2013). Alkaliphilic microbes were grown and isolated from recovered core samples. Genomic DNA was extracted from cultivable isolates and used to sequence their 16S rRNA gene to identify them and perform phylogenetic studies. Microbial assays provided insight into the biochemical processes of microbes that have been under the unique pressures of serpentinization. Finally, cellular proliferation was measured relative to pH tolerances. These qualitative studies allowed us to explore the metabolic capabilities of microorganisms in a serpentinite-hosted subsurface biosphere. Furthermore, this research helped us look into the habitability of microbes in extreme environments as well to examine their potential use in future bioremediation projects.

Download or read book Paleopalynology written by Alfred Traverse and published by Springer Science & Business Media. This book was released on 2007-05-21 with total page 816 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides complete coverage of all aspects of the study of all fossil palynomorphs yet studied. It is a profusely illustrated treatment. The book serves both as a student text and general reference work. Palynomorphs yield information about age, geological and biological environment, climate during deposition, and other significant factors about the enclosing rocks. Extant spores and pollen are treated first, preparing the student for more difficult work with fossil sporomorphs and other kinds of palynomorphs. An appendix describes laboratory methods. The glossary, bibliographies and index are useful tools for study of the literature.

Book excerpt: Earth is undergoing constant changes from the beginning of its formation. After the formation of the planet around 4.54 billion years ago, it has been changing ever since. In the beginning, it was in a liquid gas form which eventually cooled down and the surface took a hard-solid form during the time period of nearly 2 billion years after the creation of the earth. First life on the surface of earth was created about 3.8 billion years ago. And only less than 5 million years ago Homo sapiens developed. Within this really short period of time of existence compared to the age of the earth, mankind has been developing fast. And the main fuel of this development has been science and the technological advancements derived from the knowledge of science. The development of science started the moment humans created fire for the first time and now the knowledge of science has become so vast and widespread that it is literally impossible for an individual to even go through the complete knowledge acquired by humans. In the knowledge and the scientific practices, the environment plays an important role. As we are surrounded by the materials of the environment, they affect every single effort of science to understand the unknown and to develop new ways of development. In every aspect of science, the environment plays an important role which cannot be neglected or overlooked. To address the effect of the atmosphere and environment around us in our everyday life as well as in the development of science, the scientists have been feeling the necessity to modify the acquired knowledge to acknowledge and understand the effects of environment on the facts explore. And this is where environmental physics comes in. Environmental physics is a part of physics which discuss and describes the effect of environment on many scientific effects and vice versa. In order to understand and face the rapid changes in the atmosphere and to make proper utilization of the discoveries conducted by science, it is important to understand the physical effects of different simulations on the environment and also to develop the ways of controlling them. This book was developed to make the readers easily understand the close interrelation of physics with biology, chemistry, and environmental science as well as providing knowledge about the interrelations within different natural forces and their effects on each other as well as on the environment. If this book is able to help the reads in understanding the deep relationship within different Book jacket.

Download or read book Don t Let the Sun Step Over You written by Eva Tulene Watt and published by University of Arizona Press. This book was released on 2004-09 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the Apache wars ended in the late nineteenth century, a harsh and harrowing time began for the Western Apache people. Living under the authority of nervous Indian agents, pitiless government-school officials, and menacing mounted police, they knew that resistance to American authority would be foolish. But some Apache families did resist in the most basic way they could: they resolved to endure. Although Apache history has inspired numerous works by non-Indian authors, Apache people themselves have been reluctant to comment at length on their own past. Eva Tulene Watt, born in 1913, now shares the story of her family from the time of the Apache wars to the modern era. Her narrative presents a view of history that differs fundamentally from conventional approaches, which have almost nothing to say about the daily lives of Apache men and women, their values and social practices, and the singular abilities that enabled them to survive. In a voice that is spare, factual, and unflinchingly direct, Mrs. Watt reveals how the Western Apaches carried on in the face of poverty, hardship, and disease. Her interpretation of her peopleÕs past is a diverse assemblage of recounted events, biographical sketches, and cultural descriptions that bring to life a vanished time and the men and women who lived it to the fullest. We share her and her familyÕs travels and troubles. We learn how the Apache people struggled daily to find work, shelter, food, health, laughter, solace, and everything else that people in any community seek. Richly illustrated with more than 50 photographs, DonÕt Let the Sun Step Over You is a rare and remarkable book that affords a view of the past that few have seen beforeÑa wholly Apache view, unsettling yet uplifting, which weighs upon the mind and educates the heart.
