The 24th Leeds-Lyon Symposium was held in London from 4th-6th September 1997, where it was hosted by the Imperial College of Science, Technology and Medicine.The meeting addressed the topic of "Tribology for Energy Conservation" and attracted a wide range of stimulating papers and speakers. Some 150 delegates from nineteen countries attended and about sixty papers were presented in fifteen sessions. These covered the topics of lubricants, wear, friction reduction, hydrodynamics, elastohydr...

This collection of fully peer-reviewed papers were presented at the 26th Leeds-Lyon Tribology Symposium which was held in Leeds, UK, 14-17 September, 1999. The Leeds-Lyon Symposia on Tribology were launched in 1974, and the large number of references to original work published in the Proceedings over many years confirms the quality of the published papers. It also indicates that the volumes have served their purpose and become a recognised feature of the tribological literature. This year'...

In this 2nd edition of Micro-Drops and Digital Microfluidics, Jean Berthier explores the fundamentals and applications of digital microfluidics, enabling engineers and scientists to design this important enabling technology into devices and harness the considerable potential of digital microfluidics in testing and data collection. This book describes the most recent developments in digital microfluidics, with a specific focus on the computational, theoretical and experimental study of micr...

We live in a society where effective communication is vital to success. Artificial intelligence (AI) automates writing and editing processes but stifles originality. Depending on AI for your writing needs results in less brain activity. Keeping your mind active helps improve cognitive function and reduces the risk of dementia.This book helps you master basic writing essentials and get through to your readers by employing appropriate words and phrases, having consistency in the type...

Terrestrial arthropods (insects, spiders, etc.) dominate the world in numbers and extreme diversity. This book presents the combined views of a physicist, a chemist, and a biologist on the fascinating interactions of these organisms with the primary source of energy on Earth, light. It describes the plethora of important phenomena observed in different spectral ranges, from ultraviolet to visible to mid-infrared. These phenomena, often unprecedented, occur at all scales - macroscopic, micr...

The Physics of Microdroplets gives the reader the theoretical and numerical tools to understand, explain, calculate, and predict the often nonintuitive observed behavior of droplets in microsystems.Microdrops and interfaces are now a common feature in most fluidic microsystems, from biology, to biotechnology, materials science, 3D-microelectronics, optofluidics, and mechatronics. On the other hand, the behavior of droplets and interfaces in today's microsystems is complica...

Open microfluidics or open-surface is becoming fundamental in scientific domains such as biotechnology, biology and space. First, such systems and devices based on open microfluidics make use of capillary forces to move fluids, without any need for external energy. Second, the "openness" of the flow facilitates the accessibility to the liquid in biotechnology and biology, and reduces the weight in space applications.This book has been conceived to give the reader the fundamental ba...

From Digital Traces to Algorithmic Projections describes individual digital fingerprints in interaction with the different algorithms they encounter throughout life. Centered on the human user, this formalism makes it possible to distinguish the voluntary projections of an individual and their systemic projections (suffered, metadata), both open (public) and closed. As the global algorithmic projection of an individual is now the focus of attention (Big Data, neuromarketing, targeted adver...

After spending over 12 years developing new microsystems for biotechnology – especially concerned with the microfluidic aspects of these devices – Jean Berthier is considered a leading authority in the field. Now, following the success of his book, Microfluidics for Biotechnology, Dr. Berthier returns to explain how new miniaturization techniques have dramatically expanded the area of microfluidic applications and microsystems into microdrops and digital microfluidics.Engineers interested ...

Transcortical aphasias is the term used for syndromes in which the ability to repeat language is relatively preserved despite marked disturbances in other linguistic domains. Although there are a number of well-known reference texts on language disturbances after acquired brain damage that uncover the classical syndromes of aphasia (e.g. conduction aphasia) in a comprehensive fashion, this monograph is unique in its coverage of the different clinical, linguistic, and neuroanatomical aspect...

Avoir le contrôle de sa vie peut être bénéfique mais aussi dangereux si des éléments extérieurs viennent la perturber. Le désir de ne plus faire partie de ce monde est une pulsion incontrôlable qui peut se jouer en quelques secondes, mais aussi se préparer en amont si on y pense depuis longetmps. C'est une douleur qui ronge de l'intérieur au cours du temps, qui nous brûle à petit feu. Cependant si on arrive à trouver les bonnes personnes au bon moment, on peut s'en sortir et repartir de l'...

This book provides clinicians and researchers with the current state-of-the-art on the pharmacological treatment of aphasia. The focus is on the role of different pharmacological agents to improve aphasia associated with stroke and to attenuate language dissolution in degenerative conditions like Alzheimer’s disease and primary progressive aphasia. This book is the first one that addresses these topics. Leaders in the field provide tutorial reviews on how focal brain injury and degeneratio...
