'A compelling narrative of the human story' TIM MARSHALL, author of Prisoners of Geography'Lively, rich and exciting... full of surprises' PETER FRANKOPAN, author of The Silk Roads_____________Sand, salt, iron, copper, oil and lithium. They built our world, and they will transform our future.These are the six most crucial substances in human history. They took us from the Dark Ages to the present day. They power our computers and phones, build our homes and offices, and create life-saving medicines. But most of us take them completely for granted.In Material World, Ed Conway travels the globe - from the sweltering depths of the deepest mine in Europe, to spotless silicon chip factories in Taiwan, to the eerie green pools where lithium originates - to uncover a secret world we rarely see. Revealing the true marvel of these substances, he follows the mind-boggling journeys, miraculous processes and little-known companies that turn the raw materials we all need into products of astonishing complexity.As we wrestle with climate change, energy crises and the threat of new global conflict, Conway shows why these substances matter more than ever before, and how the hidden battle to control them will shape our geopolitical future. This is the story of civilisation - our ambitions and glory, innovations and appetites - from a new perspective: literally from the ground up.

Anvendt elektroteknik – forsyningsanlæg til elektriske installationer er en lærebog, der retter sig mod studerende, som ønsker at opnå kompetencer inden for højspændingsteknik. Bogen har særlig fokus på, at læseren får et overblik og kan se den systematik, der er fælles for transmissionsnettet og distributionsnettet. Anvendt elektroteknik – forsyningsanlæg til elektriske installationer gør sig fri af specifikke typer effektafbrydere og behandler mere generelle indstillinger. Bogen benytter impedansmetoden, der er en enkel metode og sikker nok til at foretage beregninger af kortslutningerne på 10 kV eller 20 kV niveau, samt på lavspændingsnettet. Bogen er målrettet de videregående tekniske uddannelser, især elinstallatøruddannelsen og maskinmesteruddannelsen, men kan også anvendes som håndbog af elrådgivere. Bogen er tillige rettet mod at opnå læringsmål svarende til el-autorisationsprøvens første opgave. Den er skrevet som et værktøj, der øger analyseniveauet hos de teknikere, elektrikere og el-ansvarligere, der arbejder med sikkerhed i elinstallationer, som er påvirket af højspændingsnettet.

This book consists of chapters written by international experts on various aspects of single molecule toroics (SMTs).The chapters cover a broad range of relevant topics and highlight the latest advances performed in the field. An up-to-date overview of the emerging SMT architectures is presented while particular attention is given to not only the magnetism and relaxation effects involved but also to the respective applications in advanced electronics and memory devices. The role that lanthanides play -especially that of dysprosium- is discussed, while a thorough analysis using theoretical/ab initio calculations is provided. Since SMTs have grown out of single molecule magnetism (SMM), it is an expanding and topical subject and the present book will engender excitement and interest amongst chemists, physicists, theoreticians and materials scientists. The volume will be of great interest to researchers and graduates working on this topic and particularly those involved in lanthanide chemistry, magnetism and theory. 

The tropical zones are dominated by developing countries, which mainly face problematic environmental issues. Different than four-season countries, tropical countries have a continuous summer-like season and therefore they are rich in clean energy sources like solar and biomass. Hence, the mitigations of environment and energy issues in the tropics would require specific understanding and different approach to solutions. This book offers an assortment of studies on scenarios of environment as well as energy demand and power generation technologies in the tropics. Many of the countries within the tropics are highly populated, and this results in various problems related to the environment and energy. The demand for energy in these countries keeps increasing but concurrently there are also environmental issues that require serious attention. As the global concern on the environment is alarming today, the choice of power generation should be of the cleanest possible resource. This various reports on research activities carried out in the tropics on the aspect of environment and energy presented in this book are highly beneficial for those who like to see an improvement in the tropics with regard to environment and energy systems.

This book provides a complete analysis of molecular communications systems from the paradigm of TCP/IP network stack, and it exploits network theories (e.g. independent functions of a layer into a stack, addressing, flow control, error control, and traffic control) and applies them to biological systems. The authors show how these models can be applied in different areas such as industry, medicine, engineering, biochemistry, biotechnology, computer sciences, and other disciplines. The authors then explain how it is possible to obtain enormous benefits from these practices when applied in medicine, such as enhancing current treatment of diseases and reducing the side effects of drugs and improving the quality of treatment for patients. The authors show how molecular communications systems, in contrast to existing telecommunication paradigms, use molecules as information carriers. They show how sender biological nanomachines (bio-nano machines) encode data on molecules (signal molecules) and release the molecules into the environment. They go on to explain how the molecules then travel through the environment to reach the receiver bio-nano machines, where they biochemically react with the molecules to decipher information. This book is relevant to those studying telecommunications and biomedical students, engineers, masters, PhDs, and researchers.
