Book excerpt: Les comprimés sont une forme galénique très populaire parmi les préparations solides grâce aux nombreux avantages proposés aussi bien aux industriels qu’aux malades. Malgré les multiples avantages, la mise au point d’un comprimé demande une connaissance approfondie des propriétés physiques et mécaniques des matières premières. Le succès de la conception des comprimés est principalement déterminé par le choix d’excipients appropriés. Pour être comprimée, la poudre doit posséder des propriétés physiques, rhéologiques et mécaniques adéquates. Elle doit d’une part avoir une fluidité qui lui permette de remplir rapidement et régulièrement la matrice de compression et d’autre part être constituée de particules qui s’agglomèrent et restent liées après la compression sans pour autant provoquer l’adhésion de la poudre sur les poinçons ou les parois de la matrice. Le collage est un des problèmes les plus fréquemment rencontrés lors de la compression. Il peut se produire à n’importe quel moment de la compression d’un lot. La résolution du problème de collage peut paraître simple : on pense immédiatement à une optimisation de la lubrification. Cependant, le collage est dû à de nombreux paramètres (conditions atmosphériques, caractéristiques physico-chimiques de l’actif et/ou des excipients, paramètres de fabrication...) qui peuvent être difficile à contrôler, surtout de manière simultanée. L’étude de faisabilité d’un comprimé orodispersible a montré que des problèmes annexes peuvent survenir après la résolution d’un phénomène de collage (friabilité non-conforme, temps de désintégration trop longs) et devenir, à leur tour, difficiles à résoudre.

Book excerpt: Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.

Available in PDF, EPUB and Kindle. Book excerpt: Many scholars, practitioners, and policy-makers in the cultural sector argue that Canadian cultural policy is at a crossroads: that the environment for cultural policy-making has evolved substantially and that traditional rationales for state intervention no longer apply. The concept of cultural citizenship is a relative newcomer to the cultural policy landscape, and offers a potentially compelling alternative rationale for government intervention in the cultural sector. Likewise, the articulation and use of cultural indicators and of governance concepts are also new arrivals, emerging as potentially powerful tools for policy and program development. Accounting for Culture is a unique collection of essays from leading Canadian and international scholars that critically examines cultural citizenship, cultural indicators, and governance in the context of evolving cultural practices and cultural policy-making. It will be of great interest to scholars of cultural policy, communications, cultural studies, and public administration alike.

Book excerpt: Covers all the soil mechanics and foundation engineering topics that are commonly included in civil engineering degree courses, and provides a number of springboards into related advanced topics. Although it is intended principally to satisfy the needs of student civil engineers, this guide should also prove useful to those practicing engineers who are unaware of the powerful and elegant reconstruction of the subject which has been made possible by the recent concepts of plasticity, dilatancy and critical states.

Available in PDF, EPUB and Kindle. Book excerpt: Experimental results and analyses are given in this report on bridge abutment scour in compound channels. Experiments were conducted in a laboratory flume with a cross section consisting of a wide floodplain adjacent to a main channel. The embankment length, discharge, sediment size, and abutment shape were varied, and the resulting equilibrium scour depths were measured. Water-surface profiles, velocities, and scour-hole contours were also measured. In the report, a methodology is developed for estimating abutment scour that takes into account the redistribution of discharge in the bridge contraction, abutment shape, sediment size, and tailwater depth. The independant variables in the proposed scour formula are evaluated at the approach-channel cross section and can be obtained froma one-dimensional water-surface profile computer program such as the Water-Surface Profile Program (WSPRO). The proposed scour evaluation procedure is outlined and illustrated, including consideration of the time required to reach equilibrium scour. The proposed methodology is applied to two cases of measured scour in the field.

Book excerpt: This volume offers exciting results, perspectives, and case studies for the treatment of problems arising in transonic aerodynamics. New advances including triple deck theory, analysis of stagnation at the nose of a body, transonic choked flow, and the transonic area rule are presented. Interest in analyzing the transonic range of flight, its stability properties, and especially the question of designing reduced drag (shockless or weak shock) airfoils keeps growing. Present day commercial aircraft cruise in the transonic range. Mechanical and aeronautical engineers interested in compressible fluid flows, design of optimal wings, and an understanding of transonic flow held about wings and airfoils will find the book invaluable. This book is understandable to those with a knowledge of continuum mechanics (fluids) and asymptotic methods. It is appropriate for graduate courses in aerodynamics and mathematical methods.

Book excerpt: Cultural planning is as important to communities as roads, rates and rubbish. Local councils and urban planners are increasingly recognising the value of community cultural resources as a means of improving the quality of life and economic vitality of a region, city or town, as well as consolidating identity and sense of place. Until now, however, there has been little Australian-based information to assist cultural planners in their task. The Cultural Planning Handbook fills the information gap with practical guidelines for mapping the cultural resources of communities and devising and implementing appropriate cultural development strategies. It is an essential guide for community development workers, planning professionals, tourism operators, artists and cultural workers as well as all community members involved in cultural development.
