Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

This collection of papers delivered at the Fifth International Symposium in Economic Theory and Econometrics in 1988 is devoted to the estimation and testing of models that impose relatively weak restrictions on the stochastic behaviour of data. Particularly in highly non-linear models, empirical results are very sensitive to the choice of the parametric form of the distribution of the observable variables, and often nonparametric and semiparametric models are a preferable alternative. Methods and applications that do not require string parametric assumptions for their validity, that are based on kernels and on series expansions, and methods for independent and dependent observations are investigated and developed in these essays by renowned econometricians.

A field bus is a two-way link between a programmable controller or operations monitor and an industrial device like a sensor, an electric motor, or a switch. It is a critical part of any automated industrial process - whether for factory automation (discrete processes like an assembly line) or process automation (continuous flow of materials being mixed, treated, or processed). PROFIBUS is a widely established program that allows for communication among and between controllers, fieldbuses, and actuator devices. This very concise introduction for industrial engineers, controls engineers, and manufacturing technicians covers the basics of field bus architecture and communication and the fundamentals of the PROFIBUS language protocol.

The Moon is the most viewed object in the sky, the Sun being too bright to look at directly and the planets too far away. The Greeks deduced everything that could be learned about the Moon using only the naked eye, including that it has no light of its own but reflects that of the Sun. They understood the cause of eclipses and used the Earth's shadow on the Moon to conclude that our planet is a sphere and to calculate the size of both the Moon and the Earth. The invention of the telescope some two millennia later offered the opportunity for much greater understanding, but the early observers became sidetracked onto a dead end: First, they fooled themselves into believing that they saw evidence of life on the Moon, even the works of a civilization. Second, they became convinced that the craters of the Moon were volcanoes like those we have on the Earth. These wrong-headed beliefs took centuries to dispel. The origin of the Moon itself has proven an even more difficult question, but scientists have now closed in on the answer. They find that our placid and seemingly unchanging Moon was born in colossal violence as a planet the size of Mars crashed into the primordial Earth and flung off a blob that solidified to become our heavenly companion. Unlocking the Moon's Secrets follows these developments to show how science evolves, complete with misunderstandings, contentious arguments, difficult to relinquish assumptions, and shifting views as new facts come to light. Thanks to the work of generations of determined scientists, we understand our Moon, at last.

Graphs are about connections, and are an important part of our connected and data-driven world. A Librarian's Guide to Graphs, Data and the Semantic Web is geared toward library and information science professionals, including librarians, software developers and information systems architects who want to understand the fundamentals of graph theory, how it is used to represent and explore data, and how it relates to the semantic web. This title provides a firm grounding in the field at a level suitable for a broad audience, with an emphasis on open source solutions and what problems these tools solve at a conceptual level, with minimal emphasis on algorithms or mathematics. The text will also be of special interest to data science librarians and data professionals, since it introduces many graph theory concepts by exploring data-driven networks from various scientific disciplines. The first two chapters consider graphs in theory and the science of networks, before the following chapters cover networks in various disciplines. Remaining chapters move on to library networks, graph tools, graph analysis libraries, information problems and network solutions, and semantic graphs and the semantic web.

As his health begins to fail, a historian in the year 2084 sets out to document the irreparable damage climate change has wrought on the planet over the course of his life. He interviews scientists, political leaders and ordinary people all around the world who have suffered its catastrophic effects, from devastating floods and mass droughts to war and famine. In a series of short chapters, we learn that much of New York has been abandoned, 50 million Bangladeshis are refugees and half of the Netherlands is under water. This is all fiction. But it is rooted in scientific fact. Written by a professor of geochemistry, James Lawrence Powell, The 2084 Report accurately chronicles the future we will face if nothing is done to address the climate crisis. A vivid portrait of climate change and its tangible impact on our lives, The 2084 Report is a powerful prophecy and urgent call to action.

From a young age many children express an interest in becoming a vet. However, the classic representation of the profession no longer fits with the realities of a modern veterinary career. Children in the 8-12 age group are encouraged to think about career options through dedicated syllabus programmes at Key Stages 2 and 3 and GCSE choices later on, but there is no veterinary career book for this age group. To Vet School and Beyond is written in an easy-to-read format, enabling the book to be a point of reference right through from pre-GSCE to A level. Bold and interactive, with plenty of illustrations and sub-sections, the book is a fresh and modern perspective on the veterinary career. For children who are curious about the veterinary world. This fun and approachable book introduces, through profiles of real vets, the different sectors beyond the familiar small animal/family vet practice in which veterinarians can work, such as research, fish veterinary, zoo medicine and charity work. It also provides some guidance in how to study to get into veterinary school.
