Administrar os pagamentos dos inúmeros tributos que incidem sobre as empresas, os quais, além de vencerem em datas variadas, são calculados sobre bases diferentes, com múltiplas alíquotas, tem sido um pesadelo para o empresariado brasileiro. Os contribuintes acabam gastando um tempo enorme e têm altos custos para compreenderem, se organizarem e cumprirem as determinações de um emaranhado de leis tributárias que se modificam continuamente. Este 9º volume da coleção LEXNET vem ao encontro do clamor empresarial por uma urgente Reforma Tributária devido à complexidade, tempo e custos despendidos para cumprimento dos deveres fiscais tributários e iniquidades que se transformaram em...

More than half the world's population now lives in cities. Creating sustainable, healthy and aesthetic urban environments is therefore a major policy goal and research agenda. This comprehensive handbook provides a global overview of the state of the art and science of urban forestry. It describes the multiple roles and benefits of urban green areas in general and the specific role of trees, including for issues such as air quality, human well-being and stormwater management. It reviews the various stresses experienced by trees in cities and tolerance mechanisms, as well as cultural techniques for either pre-conditioning or alleviating stress after planting. It sets out sound planning, design, species selection, establishment and management of urban trees. It shows that close interactions with the local urban communities who benefit from trees are key to success. By drawing upon international state-of-art knowledge on arboriculture and urban forestry, the book provides a definitive overview of the field and is an essential reference text for students, researchers and practitioners.
We live in a noisy world! In all applications (telecommunications, hands-free communications, recording, human-machine interfaces, etc.) that require at least one microphone, the signal of interest is usually contaminated by noise and reverberation. As a result, the microphone signal has to be "cleaned" with digital signal processing tools before it is played out, transmitted, or stored. This book is about speech enhancement. Different well-known and state-of-the-art methods for noise reduction, with one or multiple microphones, are discussed. By speech enhancement, we mean not only noise reduction but also dereverberation and separation of independent signals. These topics are also covered ...

“Essential reading for historians of [Francis’s] papacy in years to come, from the New York Times–bestselling author of The Reformer and Let us Dream.” —The Tablet Austen Ivereigh’s colorful, clear-eyed portrait of Pope Francis takes us inside the Vatican’s urgent debate over the future of the church in Wounded Shepherd This deeply contextual biography centers on the tensions generated by the pope’s attempt to turn the Church away from power and tradition and outwards to engage humanity with God’s mercy. In turbulent meetings and on global trips, history’s first Latin-American pope has attempted to reshape the Church to evangelize the contemporary age. At the same time, h...
The main topic of the book are the superconducting dipole and quadrupole magnets needed in high-energy accelerators and storage rings for protons, antiprotons or heavy ions. The basic principles of low-temperature superconductivity are outlined with special emphasis on the effects which are relevant for accelerator magnets. Properties and fabrication methods of practical superconductors are described. Analytical methods for field calculation and multipole expansion are presented for coils without and with iron yoke. The effect of yoke saturation and geometric distortions on field quality is studied. Persistent magnetization currents in the superconductor and eddy currents the copper part of ...
