This series of short texts provides accessible accounts of a range of essential topics in chemistry and chemical engineering. Written with the needs of the student in mind, the " Oxford Chemistry Primers " offer just the right level of detail for undergraduate study, and will be invaluable as a source of material commonly presented in lecture courses yet-not adequately covered in existing texts. All the basic principles and facts in a particular area are presented in a clear and straightforward style, to produce concise yet comprehensive accounts of topics covered in both core and specialist courses. Many of today's best selling drugs are first made in the chemical laboratory on a very small scale many years before they enter the market place. During the intervening period, organic chemists investigate alternative methods both to improve the overall yield of the process and to ensure that it operates safely on a manufacturing scale. "Top Drugs : Top Synthetic Routes" reviews the syntheses of the best selling drugs used in tackling many of the major categories of human disease cardiovascular, gastrointestinal, central nervous system, inflammatory and infectious diseases-comparing the original research method used in the discovery programme with more recent approaches aimed Ether at improving the development route or at validating newer methodologies or reagents in the context of drug synthesis. This Primer clearly explains how an understanding of modern organic chemistry is pivotal to the overall drug discovery process and will allow students to see how the organic chemistry taught in undergraduate courses is applied by medicinal chemists in industry.

The Golden Retriever, with its glamourous good looks and kindly disposition, is now firmly established as one of the world''s most popular companion dogs. The Golden was developed in the nineteenth century by Lord Tweedsmouth at his country seat in Guisachan, Scotland, and soon this intelligent, biddable worker was sought after both in Britain and overseas. Today the Golden Retriever is still highly prized as a versatile gundog, retrieving game over land and water, and it has also excelled in other spheres of activity. It is widely used as a guide dog for the blind, and this cheerful, extrovert breed is ideally suited to working as an assistance dog for the disabled and as a hearing dog for the deaf. Quick to learn and eager to please, the Golden Retriever has also made its mark in the competitive sports of Field Trails, Working Trails, Agility, and Obedience. The Golden''s handsome looks ensures its success in the show ring, but perhaps most important, the Golden Retriever is the perfect companion dog. In The Ultimate Golden Retriever, 2nd Edition, Editor Valerie Foss has recruited a start-studded cast of specialists to write the definitive book on the breed. Experts from all over the world have pooled resources to give the most comprehensive coverage of the Golden Retriever today. Starting with in-depth research into the origins and development of the breed, the experts go on to analyze the Breed Standard in detail. A unique feature of The Ultimate Golden Retriever is "The Judge''s View," in which an American, British, and German judge make a pictorial critique of six different Golden Retrievers. The Ultimate Golden Retriever, lavishly illustrated with more than 200 colorphotographs, is a must-have reference for the true Golden enthusiast.

A cultura ambiental dos galegos e galegas agroma dunha ética e dunha sensibilidade que se configuran ao longo da historia. Neste libro Díaz-Fierros achéganos a un ensaio no que analiza as orixes e a evolucion do pensamento sobre os limites dos recursos naturais da sociedade galega.

This is a brand new edition of the book that was called ‘the most beautiful chemistry book ever written’. In it, we see the molecules responsible for the experiences of our everyday life - including fabrics, drugs, plastics, explosives, detergents, fragrances, tastes, and sex. With engaging prose Peter Atkins gives a non-technical account of an incredible range of aspects of the world around us, showing unexpected connections, and giving an insight into how this amazing world can be understood in terms of the atoms and molecules from which it is built. The new edition has dozens of new molecules, a completely new graphical presentation, and an even more accessible and enthralling account of the molecules themselves.

Esta sección describe algunos pasos prácticos para aquellos que deseen enseñar la Química a lo largo de las líneas descritas en el Proyecto de Enseñanza de la Ciencia según Nuffield. El profesor, si no esta familiarizado ya con los metodos, debe prepararse para cambiar a un estilo de enseñanza que supone mucha participacion de los alumnos tanto en el trabajo de laboratorio como en la discusion de las clases. La preparacion del profesor ha de ser mas a fondo y, sin embargo, mas flexible -hay mas trabajos practicos que realizar y al mismo tiempo ha de encontrarse presto para tratar las nuevas ideas que surjan en la clase-. Esto puede implicar la necesidad de realizar algun experimento que no se habia pensado, seguir una discusion a lo largo de lineas inesperadas y encontrarse algunas veces en condiciones de tener que decir: “No lo se. Lo buscare en los libros”. EL MANUAL DEL PROFESOR constituira una leccion fundamental util para el profesor, y es una obra de referencia que deberian poseer todos los profesores de Quimica. Lo mismo puede decirse de la COLECCION DE experimentos. En este ultimo libro, todos los experimentos descritos en el CURSO MODELO y otros mas se agrupan por temas. Son “experimentos ensayados”, es decir, han sido sometidos a prev

Desarrolla los diferentes ejercicios que se presentan en el cálculo diferencial, empleando el gran programa MATLAB. Para ello, se explican los comandos necesarios del programa que logran la optimizacion de los procesos en los ejercicios de limites y derivadas. Este libro tiene como objetivo constituir un aporte para aproximar a los usuarios a este software, el cual es utilizado para optimizar procesos y ahorrar tiempo para el diseño, la manufactura o las ventas de productos. En su contenido, se tratan temas relacionados con el calculo de limites y derivados, entre otros

Basado en los más recientes descubrimientos en genética molecular y en genética del desarrollo, sin olvidar los recuestionamientos de la peleontología, este libro enriquece la teoría sintética de la evolucion tal como estaba formulada desde los trabajos de Dobzhansky, Mayr y Simpson. Contestando a las preguntas que se plantean los cientificos, estudiantes y todos los que se interrogan sobre las leyes que rigen el universo, este balance critico muestra lo esencial de la nueva sintesis evolutiva tal como se desprende de las numerosas investigaciones multidisciplinarias llevadas a cabo en el transcurso de las ultimas decadas.

La presente publicación expone un conjunto de soluciones a problemas desarrollados, usando como base los comandos del MATLAB. Asimismo, se utilizan las TIC aplicadas a las ciencias y a la ingeniería.

Este libro tiene como objetivo la elaboración de material didáctico para el estudio y aplicación práctica del Diseño de Experimentos. Se hace referencia y se explican los dos paquetes estadísticos má

Perry R Hinton, Charlotte Brownlow, Isabella McMurray, Bob CozensSPSS Explained provides the student with all that they need to undertake statistical analysis using SPSS, guiding the student from the basic rationale behind the statistics, through detailed explanations of the procedures, and finally to all aspects of the SPSS output. The SPSS output is explained in a unique way: for each part of the output the explanation is divided into both an essentials section and an advanced section. The essentials section covers the basics that the student will need to write up statistics for a research report. The advanced section provides the more advanced student with an explanation for every part of the output to help with further understanding of the statistics. SPSS Explained is supported by Perry Hinton's highly successful textbook Statistics Explained which outlines all the major statistical tests used by undergraduates in psychology and the social sciences. Both books will be warmly welcomed by students at all levels, and by the lecturers who teach them. The authors collectively have many years' experience of teaching statistics to undergraduates in the social sciences. They all have current teaching expertise and deal with student SPSS questions on a daily basis.
