Free Download Arne Gennerich, "Optical Tweezers: Methods and Protocols "
English | ISBN: 1071622285 | 2022 | 771 pages | EPUB | 105 MB
This detailed volume explores a wide variety of techniques involving optical tweezers, a technology that has become increasingly more accessible to a broad range of researchers. Beginning with recent technical advances, the book continues by covering the application of optical tweezers to study DNA-protein interactions and DNA motors, protocols to perform protein (un)folding experiments, the application of optical tweezers to study actin- and microtubule-associated motor proteins, and well as protocols for investigating the function and mechanical properties of microtubules and intermediate filaments, and more. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.

Free Download Open Design and Innovation : Facilitating Creativity in Everyone By Leon Cruickshank
2014 | 188 Pages | ISBN: 1409448541 | EPUB | 1 MB
Open innovation, crowd sourcing, democratised innovation, vernacular design and brand fanaticism are amongst a handful of new approaches to design and innovation that have generated discussion and media coverage in recent years. In practice, these ideas are often inspiring propositions rather than providing pragmatic strategies. Open Design and Innovation develops the argument for a more nuanced acknowledgement and facilitation of 'non-professional' forms of creativity; drawing on lessons from commercial design practice; theoretical analysis and a wider understanding of innovation. Specifically this book examines: innovation and design, the reality and myth of mass creativity and the future of the design profession, through a series of case studies of new approaches to open design practices. The text draws on academic research, practical experience of the author in delivering open design projects and first hand interviews with leaders in the fields. The author challenges the notion of the designer as 'fountain-head' of innovation and, equally, the idea of 'user creativity' as a replacement for traditional design and innovation. The book offers a critique of the hype surrounding some of the emerging phenomena and a framework to help understand the emerging relationship between citizens and designers. It goes on to propose a roadmap for the development of the design profession, welcoming and facilitating new modes of design activity where designers facilitate creative collaborations.

Free Download Online Hate Speech: Analysis, Detection, and Mitigation
English | 2025 | ISBN: 3031865944 | 240 Pages | PDF EPUB (True) | 12 MB
This book informs readers on how to understand, detect, and mitigate hate speech in online social media. The authors first cover the definition of hate speech and how its prevalence can be measured on online social media platforms using text and graph-based methods. The book then describes the process of detecting hate speech and presents a comprehensive account of the AI models that are currently being used. Further, the authors discuss the associated challenges that must be overcome while using these models. The book concludes with an overview of the mitigation techniques for hate speech, including blocking or suspension of the accounts (hard technique) and counterspeech (soft technique), and a discussion of the effects of these techniques on social media platforms.

Free Download Fred E. C. Culick, Spencer Dunmore - On Great White Wings: The Wright Brothers and the Race for Flight
McArthur & Company | 2001 | ISBN: 155278214X | English | 182 pages | PDF | 115.93 MB
On the eve of the hundredth anniversary of the historic events at Kitty Hawk comes a splendidly illustrated account of the legendary twelve-second flight that changed the world forever. On December 17, 1903, Orville and Wilbur Wright took to the air for less than a minute, accomplishing what mankind had only dreamed of for centuries. Now, almost one hundred years later, this definitive account offers a unique look at the Wright Brothers' achievement, and at the many experiments that led up to their momentous ride. Revealing the brothers' youthful interest in technology and flight, the authors recount the trials and errors of other would-be aviators, and explain how the race to be the first man aloft became an international obsession. Readers will learn how The Flyer - the Wright Brothers' original plane - was built, and how its indefatigable inventors solved the challenges that stumped their predecessors. And finally there is the historic flight itself - what went wrong and what, amazingly, went right - and the enormous impact the Wright Brothers had on their own and future generations. Written in engaging, accessible prose and, featuring more than 200 photographs and illustrations, On Great White Wings will delight anyone interested in the history of flight and in the fantastic story behind the twentieth century's most important achievement.

Free Download Offender Reentry and Cognitive Intervention : Propensity Score Matching Utility for Outcome Assessment By Ken Balusek
2014 | 161 Pages | ISBN: 1593327234 | PDF | 1 MB
The mass incarceration policies of recent decades have created the corresponding realization that the vast majority of these individuals will someday be released back into society. Failure to properly prepare these individuals for their return to society will result in a large number of these individuals returning to prison. This research uses propensity score matching to create comparison groups in order to evaluate a cognitive intervention program designed to reduce recidivism. Survival analysis reveals that offenders who completed the program were less likely to recidivate and their survival time was longer when compared to offenders who did not complete the program.

Free Download Julian P. McCreary, "Observations and Dynamics of Circulations in the North Indian Ocean "
English | ISBN: 9811958637 | 2023 | 536 pages | EPUB | 98 MB
The book is the first to focus on the physical oceanography of the North Indian Ocean (NIO), a special region of the global ocean that exhibits a distinct seasonality due to the impact of the South Asian Monsoon (SAM). It is written as a textbook about the NIO for graduate students, lecturers, and researchers in physical oceanography. It will also be useful for courses on the interior, coastal, and equatorial dynamics in any other ocean. It helps readers, particularly new entrants to the field, to gain a comprehensive understanding of tropical-ocean dynamics by: developing from first principles the equation set for the linear continuously stratified (LCS) model, which has long been used to study tropical oceans; and then obtaining solutions that explore different aspects of the dynamics.
