Emerging Energy Alternatives for Sustainable Environment
Sustainability of environment is an emerging global issue at present. Unsustainable or deteriorating environment is a matter of concern as it has threatened the survival of living creatures. Recently, climate change has been a matter of great concern at a global platform owing to imbalances in natural environment. Increasing population has increased the demand for energy, which has ultimately put pressure on natural resources and caused a paradigm shift from resource generation to exploitation. Emerging Energy Alternatives for Sustainable Environment aims to address the role of sustainable technologies in energy generation options for clean environment. It covers a wide spectrum of energy ge...
Conesa
Aquesta guia d&’itineraris ens endinsa en el terme municipal de Conesa, a la Conca de Barberà. Són recorreguts per caminar plausiblement, preferiblement en família, tot i que hi ha excursions que requereixen estar preparat, en un entorn equilibrat, amb una esponerosa vegetació cap a la vall de Saladern o bé amb un serret més aspre, si pugeu cap a Forès... En qualsevol cas, caminareu dins d&’un marc d&’equilibri, pau i solitud. «De Conesa, la bellesa» afirma la tradició popular. La majoria de la vintena d&’itineraris del llibre comencen en aquesta població, concretament a la font del Pati, i transcorren entre els 600 i 900 metres d&’altitud, sense sortir de la comarca natural de la Baixa Segarra, tot i fer-se alguna incursió a la veïna Segarra. Les excursions han estat pensades per fer-se a peu, però la naturalesa de la majoria dels itineraris fa també molt recomanable realitzar-les en bicicleta de muntanya o a cavall. En la fitxa tècnica de cada excursió s&’informa del quilometratge, el temps i el desnivell de l&’itinerari.
Excursions pel Tarragonès
Tota guia excursionista reclama ser escrupulós i sistemàtic a l'hora de descriure els itineraris, però el que amoroseix aquestes fredes descripcions quilomètriques sóc les informacions històriques, els matisos del paisatge, apunts sobre geologia i vegetació i opinions divertides que afegeix l'autor. El recull de rutes i camins per la comarca del Tarragonès (i en alguns casos per l'alt Camp i el Baix Penedès), té dues grans parts: en primer lloc, itineraris circulars, que s'inicien i acaben en el mateix lloc; i en segon lloc, els camins de ronda. Tots els indrets que es volen fer conèixer han estat pensats per fer-se a peu, i, sovint, també en bicicleta de muntanya.

Thermal Energy Storage
The ability of thermal energy storage (TES) systems to facilitate energy savings, renewable energy use and reduce environmental impact has led to a recent resurgence in their interest. The second edition of this book offers up-to-date coverage of recent energy efficient and sustainable technological methods and solutions, covering analysis, design and performance improvement as well as life-cycle costing and assessment. As well as having significantly revised the book for use as a graduate text, the authors address real-life technical and operational problems, enabling the reader to gain an understanding of the fundamental principles and practical applications of thermal energy storage technology. Beginning with a general summary of thermodynamics, fluid mechanics and heat transfer, this book goes on to discuss practical applications with chapters that include TES systems, environmental impact, energy savings, energy and exergy analyses, numerical modeling and simulation, case studies and new techniques and performance assessment methods.
Theoretische und experimentelle Untersuchungen zur Weiterentwicklung von solaren Partikelreceivern
Die vorliegende Arbeit beschäftigt sich mit der Modellierung eines solaren Partikelreceivers. Beim Partikelreceiver handelt es sich um ein Konzept zur Absorption konzentrierter solarer Strahlung mit Hilfe von Feststoffpartikeln. Zunächst wird der aktuelle Stand der Wissenschaft und Technik beleuchtet. Es werden verschiedene Konzepte für Partikelreceiver beschrieben und anhand festgelegter Kriterien bewertet. Der Fallfilmreceiver, bei dem die Absorption der konzentrierten Solarstrahlung in einem Vorhang aus fallenden Partikeln erfolgt, ist vielversprechend für die großtechnische Stromerzeugung. Der aktuelle Stand der Technik bezüglich der Modellierung von Fallfilmreceivern wird vorgeste...

Tourism and Dictatorship
Following WWII, the authoritarian and morally austere dictatorship of General Francisco Franco's Spain became the playground for millions of carefree tourists from Europe's prosperous democracies. This book chronicles how this helped to strengthen Franco's regime and economic and political standing.
