El diccionari UB anglès-català és el resultat d’una activitat conjunta de diferents agents que, de manera complementària, han sumat coneixements, continguts i tecnologia per fer una obra de referència rigorosa, posada al dia, útil a un ampli sector de la ciutadania i que contribueixi a eixamplar els horitzons culturals i lingüístics no solament de la comunitat universitària, sinó de la societat catalana...Pel seu contingut, constitueix una obra idònia tant per als usuaris comuns de la llengua com per a especialistes d’un ampli ventall de sectors professionals, així com per al professorat i estudiants universitaris i de cursos avançats de secundària. La mobilitat estudiantil a nivell internacional el converteix en un company de viatge imprescindible per als estudiants catalans que viatgen a l’estranger i en una eina bàsica per al coneixement de la llengua i la cultura catalanes per als qui vénen a completar els seus estudis al nostre país.
The Raman effect is a most useful tool for the study of molecular vibrations and molecular structure. Information about the structure and symmetry of molecules, as well as about their vibrational energies can be obtained to a reasonable degree of satisfaction from their infrared and Raman vibrational spectra. The body of knowl edqe of the vibrational infrared and Raman spectra of molecules is immense and is now so well organized and understood that it is found to be represented in any stan dard upper level undergraduate curriculum in chemistry. The rotational energies of a molecule and quantitative details about its structure can only be obtained through the techniques of microwave, and high-resolution infrared and Raman spectroscopy of low pressure gases and vapors. The results of such investigations are of interest . not only to the academic scientists, but also to scientists and engineers who are active in applied fields of chemistry and physics, as well as the atmospheric sciences. This book deals with basic investigations of the Raman scattering of light by gases, with some attention also being given to liquid substances. After a brief in troductory chapter that delineates the historical development of Raman spectroscopy of gases, high-resolution rotation-vibrational and pure rotational Raman spectros copy is described in Chapters 2 and 3. The all-important intensity parameter, the Raman scattering cross section, is treated in Chapter 4, while the broadening of Raman lines due to the effects of intermolecular forces is taken up in Chapter 5.
This conference is an international forum to discuss fundamental and applied research associated with the formation of spectral line profiles. It includes research involving line profiles observed in absorption, emission, and scattering by laboratory and astrophysical sources. The conference brings together specialists from many diverse fields to discuss common aspects of line shape theory and experiments. Areas covered in the conference included: laser-produced plasmas, magnetically confined plasmas, stellar atmospheres, molecular and atomic systems, high-resolution spectroscopic applications and measurements, collision-induced effects, and ultracold regimes. Papers on experiments, theory, and applications are included in this volume.
Travelers can let the stars be their guide with this Michelin Red Guide that groups attractions in three categories: three stars, famous sites not to be missed; two stars, really must sees; and one star, make an effort to see if time permits.
Reissue of Encyclopedia of Physics / Handbuch der Physik, Volume VIa The mechanical response of solids was first reduced to an organized science of fairly general scope in the nineteenth century. The theory of small elastic deformations is in the main the creation of CAUCHY, who, correcting and simplifying the work of NAVIER and POISSON, through an astounding application of conjoined scholarship, originality, and labor greatly extended in breadth the shallowest aspects of the treatments of par of bodies by GALILEO, LEIBNIZ, JAMES BERNOULLI, PARENT, DANIEL BER ticular kinds NOULLI, EULER, and COULOMB. Linear elasticity became a branch of mathematics, culti vated wherever there were mathematicians. The magisterial treatise of loVE in its second edition, 1906 - clear, compact, exhaustive, and learned - stands as the summary of the classical theory. It is one of the great "gaslight works" that in BOCHNER'S words! "either do not have any adequate successor[s] . . . or, at least, refuse to be super seded . . . ; and so they have to be reprinted, in ever increasing numbers, for active research and reference", as long as State and Society shall permit men to learn mathe matics by, for, and of men's minds. Abundant experimentation on solids was done during the same century. Usually the materials arising in nature, with which experiment most justly concerns itself, do not stoop easily to the limitations classical elasticity posits.
