This third edition of the Boiler Operator's Handbook is intended to help such operators in the quest for improved operability and performance of their boilers and their plants. The theme of this book is to "operate wisely". The goal is to instill not only "know how" but "know why". The main details have been provided by the original author, Mr. Ken Heselton. This updated version has been somewhat expanded to include a wider range of examples and some of the more recent environmental requirements. To illustrate these points, topics include multi boiler operations, understanding the plant load, maintenance issues, and controls. Every plant is different. However, it is hoped that with the information provided in this book, the wise operator will be able to address the various unique issues posed by the specific plant and provide timely solutions to meet the present-day requirements. This 3rd edition of the Boiler Operator's Handbook is intended to help operators in the quest for improved operability and performance of their boilers and their plants.

English | 2021 | ISBN: 1789144353 | 433 pages | True PDF | 15.98 MB Blood, Sweat and Earthis a hard-hitting historical exposé of the diamond industry, focusing on the exploitation of workers and the environment, and the monopolization of uncut diamonds, and how little this has changed over time. It describes the use of forced labour and political oppression by Indian sultans, the Portuguese in Brazil, and South African industrialists, as well as the hoarding of diamonds to maintain high prices, from the English East India Company to De Beers.  English | 2021 | ISBN: 0367654482 | 441 pages | True PDF | 54.3 MB Distributed and peer-to-peer (P2P) applications are increasing daily, and cyberattacks are constantly adopting new mechanisms to threaten the security and privacy of users in these Internet of Things (IoT) environments. Blockchain, a decentralized cryptographic-based technology, is a promising element for IoT security in manufacturing, finance, healthcare, supply chain, identity management, e-governance, defence, education, banking, and trading. Blockchain has the potential to secure IoT through repetition, changeless capacity, and encryption.  English | 2022 | ISBN: 9811221510 | 481 pages | True PDF EPUB | 68.19 MB This textbook focuses on distributed ledger technology (DLT) and its potential impact on society at large. It aims to offer a detailed and self-contained introduction to the founding principles behind DLT accessible to a well-educated but not necessarily mathematically oriented audience. DLT allows solving many complicated problems arising in economics, banking, and finance, industry, trade, and other fields. However, to reap the ultimate benefits, one has to overcome some of its inherent limitations and use it judiciously. Not surprisingly, amid increasing applications of DLT, misconceptions are formed over its use. The book thoroughly dispels these misconceptions via an impartial assessment of the arguments rooted in scientific reasoning.Blockchain and Distributed Ledgers: Mathematics, Technology, and Economics offers a detailed and self-contained introduction to DLT, blockchains, and cryptocurrencies and seeks to equip the reader with an ability to participate in the crypto economy meaningfully.

English | 2021 | ISBN: 9811233446 | 591 pages | True PDF | 12.46 MB Assuming basic knowledge of special and general relativity, this book guides the reader to problems under consideration in modern research, concerning black holes, wormholes, cosmology, and extra dimensions. Its first part is devoted to local strong field configurations (black holes and wormholes) in general relativity and its most relevant extensions: scalar-tensor, f(R), and multidimensional theories. The second part discusses cosmology, including inflation and problems of a unified description of the whole evolution of the universe. The third part concerns multidimensional theories of gravity and contains a number of original results obtained by the authors. Expository work is conducted for a mechanism of symmetries and fundamental constants formation. The original approach to nonlinear multidimensional gravity that is able to construct a unique perspective describing different phenomena is highlighted.Much of the content was previously presented only in journal publications and is new for book contents, e.g., on regular black holes, various scalar field solutions, wormholes and their stability, inflation, clusters of primordial black holes, and multidimensional gravity. The last two topics are added in this new edition of the book. The other chapters are also updated to include new discoveries like the detection of gravitational waves.  English | 2021 | ISBN: 1119737591 | 317 pages | pdf, epub | 17.2 MB Pollution due to various anthropogenic activities continues to increase. In terms of water pollutants, organic and inorganic pollutants are the most problematic. Although several measures have been proposed and implemented to prevent or reduce contamination, their increased concentration in water bodies has created serious concerns. Over the years, the problem has been aggravated by industrialization, urbanization and the exploitation of natural resources. The direct discharge of wastewater contaminants and their geographical mobilization have caused an increase in concentration in ground, surface, fluvial and residual waters. Extensive information about detection and disposal methods is needed in order to develop technological solutions for a variety of environments, both urban and rural. |
