Available in PDF, EPUB and Kindle. Book excerpt: Se aborda uno de los temas más importantes de la durabilidad de estructuras de hormigón armado, la modelización de la penetración de agentes activadores de la corrosión de la armadura. Actualmente, la durabilidad del hormigón se basa principalmente en dotarle de resistencia mecánica suficiente y recubrir la armadura con un espesor de hormigón que se calculan sin tener en cuenta la velocidad de penetración de los agentes agresivos; por lo que se ha comprobado en la práctica que la mayoría de las estructuras que presentan corrosión tienen un espesor de recubrimento insuficiente. Así pues, en la actualidad es objetivo de diversos investigadores el desarrollo de métodos de cálculo del recubrimiento basados en parámetros de la microestructura del hormigón y de la agresividad del medio ambiente. En definitiva, en la presente ...

Available in PDF, EPUB and Kindle. Book excerpt: The Archaeology of the Spanish Civil War offers the first comprehensive account of the Spanish Civil War from an archaeological perspective, providing an alternative narrative on one of the most important conflicts of the twentieth century, widely seen as a prelude to the Second World War. Between 1936 and 1939, totalitarianism and democracy, fascism and revolution clashed in Spain, while the latest military technologies were being tested, including strategic bombing and combined arms warfare, and violence against civilians became widespread. Archaeology, however, complicates the picture as it brings forgotten actors into play: obsolete weapons, vernacular architecture, ancient structures (from Iron Age hillforts to sheepfolds), peasant traditions, and makeshift arms. By looking at these things, another story of the war unfolds, one that pays more attention to intimate experiences and anonymous individuals. Archaeology also helps to clarify battles, which were often chaotic and only partially documented, and to understand better the patterns of political violence, whose effects were literally buried for over 70 years. The narrative starts with the coup against the Second Spanish Republic on 18 July 1936, follows the massacres and battles that marked the path of the war, and ends in the early 1950s, when the last forced labor camps were closed and the anti-Francoist guerrillas suppressed. The book draws on 20 years of research to bring together perspectives from battlefield archaeology, archaeologies of internment, and forensics. It will be of interest to anybody interested in historical and contemporary archaeology, human rights violations, modern military history, and negative heritage.

This book was released on 1993-01-01 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: This design code for concrete structures is the result of a complete revision to the former Model Code 1978, which was produced jointly by CEB and FIP. The 1978 Model Code has had a considerable impact on the national design codes in many countries. In particular, it has been used extensively for the harmonisation of national design codes and as basic reference for Eurocode 2. The 1990 Model Code provides comprehensive guidance to the scientific and technical developments that have occurred over the past decade in the safety, analysis and design of concrete structures. It has already influenced the codification work that is being carried out both nationally and internationally and will continue so to do.

Book excerpt: Overall, this book illustrates the complexities of the regulation and deregulation of genes mediated through epigenetics in the development and progression of human malignancies. All the articles have been carefully chosen to represent several cancer systems with state of our knowledge on the role of epigenetic deregulation of microRNAs (miRNAs) and their target mRNAs along with epigenetic deregulation of mRNAs. This book also illustrates the role of several dietary agents, collectively called nutraceuticals or natural agents in modulating the epigenetic reprogramming of miRNAs and mRNAs for the prevention and/or treatment of human malignancies. It is well known that genetic aberrations, especially inherited through parents (somatic genetic alterations) contribute to the development of less than 10% of all cancer yet epigenetic alterations in genes especially through selective methylation and acetylation appears to be responsible for the development and progression of the vast majority of all cancers. Therefore, understanding the role of epigenetics in the regulation of genes especially through deregulated expression of miRNAs as presented in this book will allow scientists to devise targeted therapeutic strategies for re-expression of the lost genes or down-regulate the genes that are over-expressed in order to eradicate cancer. It is hoped that targeting epigenetics will not only target cancer cells but it will also target the tumor microenvironment (more like the entire tumor environment such as the entire host) for achieving better treatment outcomes for patients diagnosed with cancer which will lead to achieve the long-term objective for complete eradication of cancer. This book contains fifteen chapters which begins with the concept of systems and network biology for investigating the epigenetics of cancer followed by a series of articles on the role of miRNAs and their target genes in the biology of pancreatic cancer and other cancers such as breast, kidney, prostate and and colon. Since it is becoming increasingly clear that cancer stem cells (CSCs) are important in the development and progression of cancer, and CSCs are important in therapeutic resistance, treatment failure and tumor recurrence, thus the importance of CSCs and epigenetics has been highlighted by a very timely article on epigenetic variations of stem cell markers in cancer including miRNAs. Moreover, just targeting heterogeneous cancer cell populations may not be optimal to eradicate tumors and for which one must take a holistic approach for developing drugs that could also target the tumor microenvironment and tumor dormancy that are regulated through epigenetics. Keeping abreast with this thought process the concluding chapter provides a concept towards curative cancer therapy with maspin, which could be a unique window of opportunity to target tumor dormancy. Therefore, it suggest that targeting the tumor dormancy and the tumor microenvironment using novel therapeutics specifically by targeting epigenetics would become the future of medicine.

Book excerpt: Asphalt pavements are easy to maintain, quick to construct, and provide a safe, smooth, quiet ride. Simply put, asphalt pavements provide the greatest level of drivability at the most economical price. Asphalt pavement refers to any paved road surfaced with asphalt. Hot Mix Asphalt (HMA) is a combination of approximately 95% stone, sand, or gravel bound together by asphalt cement, a product of crude oil. Asphalt cement is heated aggregate, combined, and mixed with the aggregate at an HMA facility. Asphalt is America's most recycled material. Reclaimed asphalt is not just reusable as a "black rock" the asphalt cement in the reclaimed pavement is reactivated to become an integral part of the new pavement.
