 English | 2022 | ISBN: 1789257778 | 257 pages | True PDF EPUB | 93.58 MB This book concerns textile production at the fringes of north-western Europe - areas in western Norway and the North Atlantic in the expanding, dynamic and transformative period from the early Viking Age into the Middle Ages. Textiles constitute one of the basic needs in human life - to protect and keep the body warm but also to show social status and affiliations. Textiles had a wide spectrum of use areas and qualities, fine and coarse in various contexts, and in the Viking Age not least related to the production of sails - all essential for the development and character of the period. So, what were the tools and textiles like, who made them, who used them and who exposed them? By tracing textile production from the remains of tools and textiles in varied landscapes and settings - Viking Age graves and in situ workplaces from the whole period - and combining this with textual information, many layers of information are exposed about technology and qualities as well as gender, gender roles, social relations, power and networks. By combining tools, textiles and texts in various settings, this book aims to contextualize dispersed archaeological finds of tools and textiles to uncover patterns across larger areas and in a long-term perspective of half a millennium.

"A gripping, stranger-than-fiction tale of how a small team of geeks and federal agents cracked what was once thought to be untraceable cryptocurrency." —Garrett M. Graff,New York Timesbestselling author ofThe Only Plane in the SkyandWatergate  English | 2022 | ISBN: 978-1685077976 | 180 pages | True PDF | 15.77 MB Trace metals are necessary for the proper functioning of living organisms and are absorbed by the body through diet or environmental exposure. However, excessive intake of trace metals can cause health problems. As such, the study of the presence of trace metals in the environment and their effects on health is important. This volume includes four chapters that provide details about trace metals in various contexts. Chapter One explains the nutritional zinc requirements of humans and discusses the usefulness of different supplements in various applications. Chapter Two addresses the different aspects of metal-microbial interactions, focusing on soil and sediment ecosystems. Chapter Three addresses pollution of heavy metals, emission sources, health implications, and commonly used methods for assessment of pollution. Lastly, Chapter Four assesses possible changes in the geochemical behavior of chromium caused by sediment resuspension in a hypereutrophic estuary that receives domestic and industrial effluents daily.

These metals are emitted to the environment mainly by anthropological sources, such as industries, extractive processes and burning of fossil fuels. This book presents the main sources of toxic metals emission, demonstrate the state of the art of waste disposal and valuation techniques, especially solids and wastewater treatment.

Technology companies and device designers correlate touchscreens and online sites with physical contact and emotional sentiments, promising unmediated experiences in which the screen falls away in favor of visceral materiality and connections. While touchscreens are key elements of most people's everyday lives, critical frameworks for understanding the embodied experiences of using them are wanting. In Touch Screen Theory, Michele White focuses on the relation between physically touching and emotionally feeling to recenter the bodies and identities that are empowered, produced, and displaced by these digital technologies and settings. Drawing on detailed cases and humanities methods, White shows how and why gender, race, and sexuality should be further analyzed in relation to touchscreen use and design.
 English | 2022 | ISBN: 0784415943 | 461 pages | True PDF | 7.63 MB Prepared by the Total Maximum Daily Load Analysis and Modeling Task Committee and sponsored by the Watershed Management Technical Committee of the Watershed Council of the Environmental and Water Resources Institute of ASCE Total Maximum Daily Load Development and Implementation: Models, Methods, and Resources , MOP 150, describes the state of the practice and provides guidance to practitioners in selecting analytical tools and models in the development of a total maximum daily load (TMDL) and its implementation plan. The MOP includes detailed descriptions of a variety of watershed and receiving water quality models that can be used, highlighting recent advances in TMDL analysis and modeling.  English | 2022 | ISBN: 0750333499 | 198 pages | True PDF EPUB | 38.36 MB This book offers a complete presentation of the physics, math, and experimental setups for both TIRF and related evanescence microscopies. It covers evanescence in both fluorescence excitation or emission. It also discusses, in detail, the theory, setups, and practical biological/biochemical applications for combinations of evanescence microscopies with other optical techniques such as polarization, photobleaching, correlation spectroscopy, scattering, image enhancement, optical force, two-photon, energy transfer, structured illumination, scanning, quenching, and single molecule detection. Physical and qualitative discussions augment the rigorous math, making the book accessible and interesting to a wide range of audiences with backgrounds from biology to chemistry to physics. The book also contains useful step-by-step guides to building, modifying, and aligning TIRF microscopy systems for specialized purposes. Key Features:  English | 2022 | ISBN: 1032345535 | 321 pages | True PDF | 41.94 MB This book is devoted to the consideration of unusual laser beams – vortex or singular beams. It contains many numerical examples, which clearly show how the phase of optical vortices changes during propagation in free space, and that the topological charge is preserved. Topological Charge of Optical Vortices shows that the topological charge of an optical vortex is equal to the number of screw dislocations or the number of phase singularities in the beam cross-section. A single approach is used for the entire book: based on M. Berry's formula. It is shown that phase singularities during beam propagation can be displaced to infinity at a speed greater than the speed of light. The uniqueness of the book is that the calculation of the topological charge for scalar light fields is extended to vector fields and is used to calculate the Poincare–Hopf singularity index for vector fields with inhomogeneous linear polarization with V-points and for the singularity index of vector fields with inhomogeneous elliptical polarization with C-points and C- lines.  English | 2022 | ISBN: 978-3110757699 | 292 pages | True PDF EPUB | 50.36 MB Complex analysis is found in many areas of applied mathematics, from fluid mechanics, thermodynamics, signal processing, control theory, mechanical and electrical engineering to quantum mechanics, among others. And of course, it is a fundamental branch of pure mathematics. The coverage in this text includes advanced topics that are not always considered in more elementary texts. These topics include, a detailed treatment of univalent functions, harmonic functions, subharmonic and superharmonic functions, Nevanlinna theory, normal families, hyperbolic geometry, iteration of rational functions, and analytic number theory. As well, the text includes in depth discussions of the Dirichlet Problem, Green's function, Riemann Hypothesis, and the Laplace transform. Some beautiful color illustrations supplement the text of this most elegant subject.

This idea was the crazy dream of concert promoter Sid Bernstein. No rock band had ever played a baseball stadium, and no one believed he could pull it off. But on that glorious night, The Beatles sold out Shea Stadium, shattering all existing box office and attendance records in show business history. Oh, and they also changed the world. Against the backdrop of a remarkably volatile year in our nation's history, Top of the Mountain: The Beatles at Shea Stadium, 1965 delivers all the detail and excitement of Shea and the spirited, curious new generation who would soon claim the decade for its own. Told through first-person interviews and quotes, a unique cast of characters tells the story: celebrities then and celebrities now, writers, agents, producers, photographers, opening act performers, fans, security guards, radio personalities, cameramen, and media—all of whom were part of the night. Caryn Johnson (Whoopi Goldberg) and Steven Lento (Little Steven Van Zandt); future Beatle wives Linda Eastman and Barbara Bach; established stars like Bobby Vinton and Ed Sullivan; and artists hoping one day to equal this success, such as Mick Jagger, Keith Richards, Felix Cavaliere and The Rascals, Marvin Gaye, and more share their memories of this remarkable night in Top of the Mountain. |
