A description of general techniques for solving linear partial differential equations by dividing space into regions to which the equations are independently applied and then assembling a global solution from the partial ones. Intended for researchers and graduates involved in calculations of the electronic structure of materials, this will also be of interest to workers in quantum chemistry, electron microscopy, acoustics, optics, and other fields. The book begins with an intuitive approach to scattering theory and then turns to partial waves and a formal development of multiple scattering theory, with applications to the solid state. The authors then present a variational derivation of the formalism and an augmented version of the theory, concluding with a discussion of the relativistic formalism and a discussion of the Poisson equation. Appendices discuss Green's functions, spherical functions, Moller operators and the Lippmann-Schwinger equation, irregular solutions, and singularities in Green's functions.
This classic work by Poucher, first published in 1923, was last produced in three volumes titled, respectively The Raw Materials of Perfumery (seventh edition, 1974), The Production, Manufacture and Application of Perfumes (eighth edition, 1974) and Modern Cosmetics (eighth edition, 1974). Its popularity is well demonstrated by there having been three reprints of these editions in 1976, 1979 and 1984, respectively. The history of events can be traced by reference to the prefaces to earlier editions and those interested should study these with care since they give a fascinating insight into developments in the subject fields covered by Poucher's Perfumes, Cosmetics and Soaps over the years. It is not proposed to provide a resume here. In this Volume I, the current edition attempts to provide data about raw materials in a more formalized way than before, so that not only the history of some compounds can be checked, but also so that useful reference information can be obtained. It is particularly relevant to do this, since it is not always easy to be certain of nomenclature. Moreover, as we move towards 'ingredient labelling' (a trend not welcomed by some), a high level of uniformity will be needed. Whether this will come from adoption of CTFA terminology, use of CAS numbers or some other system is not clear. Where possible, such data have been included so that readers may identify materials more readily. Where given, CAS numbers are located in the top right-hand corner of each entry.
Museum professionals' increased focus on visitors in recent years has been demonstrated by, among other things, the enhanced practice of evaluation and the development of interpretive plans. Yet too often, these efforts function independent of one another. This book helps museums integrate visitors' perspectives into interpretive planning by recognizing, defining, and recording desired visitor outcomes throughout the process. The integration of visitor studies in the practice of interpretive planning is also based on the belief that the greater our understanding, tracking, and monitoring of learners, the greater the impact museums will make on public understanding of the science and humanities disciplines. An approach that advocates thoughtful and intentional interpretive planning that constantly integrates visitor perspectives is the next step in working with, rather than for, our communities; a step toward truly becoming visitor-centered and impactful as essential learning institutions of the 21st century.
In this one-of-a-kind volume, museum staff and social scientists begin to explore the many facets of the relationship between museums and families. They examine the museum's importance to the family as a source for socialization and learning. At the heart of this exciting book is a concentration on developing programs of experiential learning and knowledge building that will assist families in understanding their history and culture.
Straight talk about what it means to be African American men. "Let's have a conversation. Let's talk man-to-man and brother-to-brother. Let's talk about how we grow into adults and what manhood means. Let's talk brother-to-brother and man-to-man about how we relate to one another as we grow into adults. Let's talk about what defines our maleness and our manhood. Let's talk brother-to-brother as African American men. Let's talk openly and honestly about what it means to be black men and American. We can no longer assume that we all know what it means to be African American men. This is a conversation that is long overdue. Let's talk together and listen to one another. This is our time to talk instead of being talked about. It is time for us to shed the unhealthy images and opinions that we have accepted as the standards of what it means to be Black men. The benefits of our talk will transform our souls as well as benefit all the girls and women in our lives." from the book
Wednesday, November 9, 2016 is the day that changed America. A Republican business mogul and reality television host who once proclaimed that if women didn’t accept the intimate advancements of men, then men were could simply grab these women by a particularly sensitive extremity below their stomachs, snatched the electoral collegiate vote and since then has worked tirelessly on reversing President Barack Obama’s progressive policies and pushing immigration legislation backwards. This vital resource guide incorporates the basic understandings of spiritual care with the current social, emotional, existential and spiritual needs of African Americans simply surviving in Trump’s violent America. It’s one-of-a-kind, offering specific spiritual care strategies and interventions for African Americans dealing with particular physical, social and emotional health challenges in the midst of rising statistics of racism, sexism, classism, and homophobia leading to violence in the United States. Intended for anyone in academia or the helping professions, this comprehensive work benefits those seeking to provide spiritual care to African American hospital patients, counseling clients, church congregants and parishioners, military veterans, or returning service members. The contributors to this anthology are experts in their respective fields who offer a new, refreshing, and energizing perspective on important issues impacting African Americans.
Here are more than two hundred recipes from Hawaii that are as varied and distinctive, as appealing and inviting as are its delightful scenery and its charming people. Polynesian to begin with, the islanders and their food have been tempered extensively--and nicely--by assimilating many of the fine traits of the Chinese, Japanese, Korean, Filipinos, Portuguese, and mainland Americans who have make Hawaii their home. All of these influences are reflected in this delightful potpourri of delectable and distinctive Hawaiian dishes. Some of them call for the generous use of the Islands luscious fruits and vegetables, or its readily available and varied products of the sea, with plenty more proving how versatile pork and poultry can be. Besides describing a kaleidoscopic variety of drinks, desserts, and main dishes, this book provides numerous menus and complete notes on how to entertain in a truly Hawaiian manner. In addition there is a glossary of Hawaiian terms and an extensive list of specialty food shops in the United States where one can find the few unusual ingredients that are called for.
Paul Sietsema makes things, then films them in order both to see them more clearly and to render them more abstract. This book contains stills from his 16mm film "Figure 3", and interview with the artists, plus plates of his work overlaying newspaper cuttings with ink or paint.
On Line: Drawing Through the Twentieth Century explores the radical transformation of drawing that began during the last century as numerous artists critically re-examined the traditional concepts of the medium. In a revolutionary departure from the institutional definition of drawing and from reliance on paper as the fundamental support material, artists instead pushed the line into real space, expanding the medium's relationship to gesture and form and connecting it with painting, sculpture, photography, film and dance. Published in conjunction with an exhibition at The Museum of Modern Art, On Line presents a discursive history of mark-making through nearly 250 works by 100 artists, including Aleksandr Rodchenko, Alexander Calder, Karel Malich, Eva Hesse, Anna Maria Maiolino, Richard Tuttle, Mona Hatoum and Monika Grzymala, among many others. Essays by the curators illuminate individual practices and examine broader themes, such as the exploration of the line by the avant-garde and the relationship between drawing and dance.
The mathematical apparatus of group theory is a means of exploring and exploiting physical and algebraic structure in physical and chemical prob lems. The existence of structure in the physical processes leads to structure in the solutions. For group theory to be useful this structure need not be an exact symmetry, although as examples of exact symmetries we have that the identity of electrons leads to permutation symmetries in many-electron wave functions, the spatial structure of crystals leads to the Bloch theory of crystal eigenfunctions, and the rotational invariance of the hydrogenic Hamiltonian leads to its factorization into angular and radial parts. In the 1930's Wigner extended what is known to mathematicians as the theory of group representations and the theory of group algebras to study the coupling coefficients of angular momentum, relating various properties of the coefficients to the properties of the abstract group of rotations in 3-space. In 1949 Racah, in a paper on rare earth spectra, showed that similar coefficients occur in other situations. Immediately a number of studies of the coefficients were begun, notably by Jahn, with his applications in nuclear physics. In the years since then a large number of physicists and chemists have added to the development of a general theory of the coefficients, or have produced specialized tables for a specific application. Applications now range from high-energy physics to biology.
For the convenience of research workers, particularly those with limited knowledge of embryology, we have put together a series of tables to enable rapid identification of specific stages of embryonic development in the more commonly used mammals. Because if its frequent usage the chick embryo is included this atlas.
When a plane carrying top Soviet officials crashes en route to an epoch-making summit in San Francisco, and a US Air Force jet missile is blamed for the crash, it suddenly looks like WW III is about to begin. USAF Colonel Jack Phillips must get past the Russians and the US military to find answers that no one seems to want him to find.
In her expressionistic drawings and paintings of the last three decades, acclaimed South African artist Marlene Dumas has focused on the human figure, probing themes of love, despair, desire and confusion in order to critique social and political attitudes towards women, children, people of colour and others who have been historically victimized. This substantial, fully illustrated volume, published on the occasion of Dumas's first major American survey, features a newly commissioned essay by renowned scholar Richard Schiff, placing the artist's work in relation to both American figurative painting since the 1980s and Abstract Expressionism. The book also includes curator Cornelia H. Butler's examination of Dumas's photographic sources and shorter texts by Lisa Gabrielle Mark and Matthew Monahan. Writings by the artist, as well as an extensive illustrated exhibition history and bibliography, complete this comprehensive examination of the work of one of the most thought-provoking artists working today.
