The propulsion system behaviour is a key aspect for the overall dynamics of a ship. However, despite its great importance, numerical methodologies for detailed investigations on marine propulsion dynamics are not yet widely covered in scientific literature. This book presents the main steps for the development of a multi-physic simulation platform, able to represent the motions of a twin screw ship in six degrees of freedom, taking into account the whole propulsion system and automation effects. A number of mathematical sub-models had been developed and calibrated by a set of experimental tests, in model and full scale. Finally, the sea trials campaign of a ship is used to validate and tune the developed simulator. The proposed simulation methodology can be used in the ship preliminary design phase, in order to plan and test the propulsion system and automation. Further applications can include the design optimization and crew training.

Research in Science Education (RISE) Volume 6, Research Based Undergraduate Science Teaching examines research, theory, and practice concerning issues of teaching science with undergraduates. This RISE volume addresses higher education faculty and all who teach entry level science. The focus is on helping undergraduates develop a basic science literacy leading to scientific expertise. RISE Volume 6 focuses on research-based reforms leading to best practices in teaching undergraduates in science and engineering. The goal of this volume is to provide a research foundation for the professional development of faculty teaching undergraduate science. Such science instruction should have short- and longterm impacts on student outcomes. The goal was carried out through a series of events over several years. The website at http://nseus.org documents materials from these events. The international call for manuscripts for this volume requested the inclusion of major priorities and critical research areas, methodological concerns, and results of implementation of faculty professional development programs and reform in teaching in undergraduate science classrooms. In developing research manuscripts to be reviewed for RISE, Volume 6, researchers were asked to consider the status and effectiveness of current and experimental practices for reforming undergraduate science courses involving all undergraduates, including groups of students who are not always well represented in STEM education. To influence practice, it is important to understand how researchbased practice is made and how it is implemented. The volume should be considered as a first step in thinking through what reform in undergraduate science teaching might look like and how we help faculty to implement such reform.

In the summer of 1783, an unusual dry fog blanketed large parts of the northern hemisphere. The fog brought with it bloodred sunsets, a foul sulfuric odor, and seemingly, a host of other peculiar weather events. Inspired by the Enlightenment, many naturalists attempted to find reasonable explanations for these occurrences. Between 8 June 1783 and 7 February 1784, unbeknown to the contemporaries outside of Iceland, a 27-kilometer-long fissure volcano erupted, producing the largest volume of lava released by any volcanic eruption on planet Earth in the last millennium. In Iceland, the eruption led to the death of one-fifth of the population. The jetstream carried its volcanic gases further afield to Europe and beyond. "The Laki Eruption of 1783" is an environmental history of the Laki eruption, which combines methods of historical disaster research, climate history, global history, history of science, and geology in an interdisciplinary approach. Icelandic Laki-sized flood lava eruptions have a statistical recurrence period of 200 to 500 years; it is crucial to understand their consequences so that we can prepare for the next one. A volcanic eruption of this scale could be disastrous for our modern, globalized, and interconnected world.

Throughout my life I have been always on the go, always looking for the next level. I ve never felt settled and comfortable, always setting the next goal as soon as the current one nears completion and pushing myself all the time. With this attitude, I felt myself under pressure most of the time, and with pressure comes stress, loads of stress, and the feeling that I never had enough time. I was burning the candle at both ends, but I concluded that this was what life required. For those of us who want to thrive and lead a healthy lifestyle in this high-pressure world of instability, confusion, constant change, and stress, we couldn t stand a chance if we were physically or mentally sluggish. So when I got to know about flotation therapy, I quickly realised that this could be the natural answer to the stresses of this ever-changing world of ours. Regular floating can be the way to relax your tired body while engaging your subconscious mind as you control your thoughts. I discovered that regular floating made me a healthier and happier person. I said goodbye to a stressful lifestyle as I exercised and reinforced my body s capacity for happy thoughts, healing, good sleep, creativity, and imagination. I had lower blood pressure, easier concentration, and more energy. I discovered how regular floating positively changed my life and helped me focus on the things I want out of life. The powerful technique of floating can help people, especially go-getters, to achieve their goals, to become much more centred, and to tackle the issues and problems that life throws at them easily and calmly. Isn t true that if we approach our problems in a relaxed state, we stand a better chance of solving them? So when I was called up to run one of the very first flotation centres in England, I was completely blown away by the difference this form of therapy made in my life. The experience of lying in a tank, a gravity-free environment, experiencing weightlessness and proper blood circulation, sold me on the idea of floating regularly. I thought of the millions of people out there with busy lifestyles like me who could find the results from floating regularly very helpful. I thought of people who may be magnesium deficient, who may be at risk of developing or already suffer from poor blood circulation, diabetes, arthritis, obesity, stroke, cancer, heart disease, fatigue, and those who may be so stressed out that they cannot even sleep at night. At the flotation centre, I started researching flotation and the difference it made in people s lives. My position at the time facilitated this research, as I always found the time to chat with all my clients about their experiences on the day to see what changes regular floating was making for them. What I found was that there was not enough information out there about how this fantastic therapy can be beneficial in the long term. I was so involved with the floating business that even my spare time was eaten up by research on the topic, and I promised myself that as soon as the opportunity arose, I would put pen to paper to let the world know in depth the benefits of being present within, switching off, and being in solitude and seclusion while spending some time in a gravity-free, sensory deprivation isolation tank for just an hour or a lunchtime holiday. Some of the long-term benefits described in this book will just blow you away. Read and digest this information and keep the book close at hand for reference. This is not just intellectual entertainment, so please do act on this book s contents for the well-being of yourself, your friends, and your family.

This excellent book represents one of the first and best presentations of Eastern wisdom in the English language. It concerns ancient Hindu traditions and the Yogic practice of observing and regulating the breath. We begin with an admission that Western students are often confused by what exactly Yoga is, and what it is meant to accomplish. Stereotypes of the yogi as spindly, dirty and disheveled men commonly seen sitting in fixed posture at a roadside or marketplace abound. Yet these dismissive images serve only to neglect the spiritual substance and ancient wisdom of yogi science. Seeking to dispel the negative stereotypes and present the vivid truth, Atkinson discusses the multiple schools of yoga and their general purpose. Some emphasize control over the body's motions, while others favor inner development of the spirit. Several however emphasize the control of the breath; and it a practical explanation of this that Atkinson relays in the remaining fifteen chapters of this book.

Russian psychiatrist Vasily Kasatkin devoted more than half a century to collecting and studying dreams and is the author of the book "Theory of Dreams" (Medical 1967). The theory Kasatkin proposes is not filled with mystical symbols, but numerous scientifically-based facts and interesting observations. His work is based on an extensive 30-year collection of dreams, which allowed Kasatkin to make significant conclusions. He demonstrates that the sleeping brain warns us of impending disease, of which the first symptoms may occur weeks, months or even years before the overt physical symptoms.

COMMERCIAL WAXES NATURAL AND SYNTHETIi Including Properties, Uses, Methods of Handling and Formulas for Making Commercial Wax Compositions. A SYMPOSIUM AND COMPILATION Edited by H. BENNETT. PREFACE: Natural waxes and wax-lifle materials have been used, from time immemorial, for candles, waterproofing, sealing, decorative, preservative, and other purposes. Synthetic waxes and wax-like materials, developed in the last decade, are finding increasing use and are supplanting natural waxes for many purposes. Since different waxes have different properties, each one is used to obtain certain end results. Whereas certain waxes are used alone, as paraffin wax in waxed papers, other uses require com binations of different waxes, resins, etc., to obtain a desired result. Because there is no one source of information available on the waxes used in industry, the writer was asked to prepare a book on commercial waxes for the chemist, engineer, superin tendent, purchasing agent, and student. It is hoped that this book will be helpful to these and others who are interested in commercial waxes and wax compositions. Much of the data given herein is from the writer's own laboratory and has never been disclosed. Grateful acknowledgment is made to Allan B. Olsen, both for data supplied by him and his constructive criticism of the manuscript. H. BENNETT. Contents include: PREFACE iii INTRODUCTION xi ABBREVIATIONS xv I.

A superbly thorough guide to psychology, William James' thesis successfully summarizes the tenets of the science in the early 20th century - this edition contains the vital notes and illustrations. Appearing in 1890, The Principles of Psychology was a landmark text which established psychology as a serious scientific discipline. William James' compiled a convincing, lengthy and broad thesis, devoting detail and vigorous analysis in every chapter. The text's comprehensiveness and superb presentation played a pivotal role in bringing the science of mental health closer toward the scholarly mainstream. The entire book is set out intuitively: there are two volumes, each of which has a certain number of chapters. While some chapters have sub-sections, James is careful not to make his textbook dry or convoluted in organisation.

There is no "you" consciously making decisions. So how do we make decisions? How can we have free will if we don't pull the levers on our own behavior? What moral and legal implications follow if we don't have free will? Who's in Charge? is a primer for a new era in the understanding of human behavior that ranges across neuroscience, psychology, ethics, and the law with a light touch but profound implications.

"Explicar una cuestion cualquiera con argumentos mas complicados parece un signo de inteligencia, pero no lo es" Esta sabia afirmacion, escrita hace muchos siglos por el filosofo (y muchas otras cosas) Aristoteles, siempre ha guiado mis pasos en la divulgacion cientifica y en la exposicion docente de temas complejos y escabrosos. Hacerse entender y facilitar a los otros el entendimiento, siempre y cuando se respete la verdad y exactitud cientificas, es la mejor manera de adelantar en la evolucion positiva de la sociedad. Con estas premisas en cuenta, vamos entonces a adentrarnos en esos territorios tan apasionantes de las leyes cientificas y el caos.
