    Heritage Regimes and the State

    What happens when UNESCO heritage conventions are ratified by a state? How do UNESCO鈥檚 global efforts interact with preexisting local, regional and state efforts to conserve or promote culture? What new institutions emerge to address the mandate? The contributors to this volume focus on the work of translation and interpretation that ensues once heritage conventions are ratified and implemented. With seventeen case studies from Europe, Africa, the Caribbean and China, the volume provides comparative evidence for the divergent heritage regimes generated in states that differ in history and political organization. The cases illustrate how UNESCO鈥檚 aspiration to honor and celebrate cultural diversity diversifies itself. The very effort to adopt a global heritage regime forces myriad adaptations to particular state and interstate modalities of building and managing heritage.What happens when UNESCO heritage conventions are ratified by a state?

    Organophosphorus chemistry is an important discipline within organic chemistry. Phosphorus compounds, such as phosphines, trialkyl phosphites, phosphine oxides (chalcogenides), phosphonates, phosphinates and >P(O)H species, etc., may be important starting materials or intermediates in syntheses. Let us mention the Wittig reaction and the related transformations, the Arbuzov- and the Pudovik reactions, the Kabachnik鈥揊ields condensation, the Hirao reaction, the Mitsunobu reaction, etc. Other reactions, e.g., homogeneous catalytic transformations or C-C coupling reactions involve P-ligands in transition metal (Pt, Pd, etc.) complex catalysts. The synthesis of chiral organophosphorus compounds means a continuous challenge. Methods have been elaborated for the resolution of tertiary phosphine oxides and for stereoselective organophosphorus transformations. P-heterocyclic compounds, including aromatic and bridged derivatives, P-functionalized macrocycles, dendrimers and low coordinated P-fragments, are also of interest. An important segment of organophosphorus chemistry is the pool of biologically-active compounds that are searched and used as drugs, or as plant-protecting agents. The natural analogue of P-compounds may also be mentioned. Many new phosphine oxides, phosphinates, phosphonates and phosphoric esters have been described, which may find application on a broad scale. Phase transfer catalysis, ionic liquids and detergents also have connections to phosphorus chemistry. Green chemical aspects of organophosphorus chemistry (e.g., microwave-assisted syntheses, solvent-free accomplishments, optimizations, and atom-efficient syntheses) represent a dynamically developing field. Last, but not least, theoretical approaches and computational chemistry are also a strong sub-discipline within organophosphorus chemistry

    Prediction of the Mechanical Properties of Molecular Crystals Based Upon Their Crystallographic Structure

    The APIs mechanical properties particularly, tabletability and flowability are of significant interest in the drug dosage tabletting. Insights into the APIs mechanical behaviour not only assist in the selection of optimum tabletting process but the choice of suitable excipients for dosage blend. Prediction of the mechanical properties of seven solid forms was described in this study two of which were used at the initial stage to develop the model. The objective of the model is to test the reliability of applying molecular and crystallographic modelling to predict the slip behaviour of APIs which will provide a quick tool for observing the mechanical properties. Plane rugosity and interlock properties were calculated for the first time by taking the crystallographic properties of each compound. The prediction model comprises of three main components. Firstly, the identification of likely dislocation Burgers vectors based on lattice geometry and dependency to line dislocation; secondly, selection of slip planes for plastic deformation using the calculation of interplanar interactions, rugosity and surface energy and thirdly, characterisations of slip systems or propensity for cleavage and fracture. The pentaerythritol and its derivative, pentaerythritol tetranitrate were selected as the basis structure during development of model because of known cleave and plastic behaviour. From the calculation, the primary Burgers vector for pentaerythritol was identified as 陆 [111], and the prominent slip plane for pentaerythritol is a non-habit plane of (001). The (001) was 94% behaving as an ideal slip plane. However, the primary slip system of pentaerythritol was inactive because the Burgers vector was not in the (001) plane. Pentaerythritol was predicted to cleave at (001) because of strong intraplanar intermolecular interactions. In contrast, pentaerythritol tetranitrate was predicted to undergo deformation by slipped on the plane (110) and in the direction of [001]. The (110) was behaving with 82% of ideal slip plane. The predicted slip behaviour was agreeing with the micro-indentation measurements in the literature. Five solid forms of paracetamol, namely polymorph I and II, paracetamol theophylline, paracetamol trihydrates and paracetamol hydrochloride monohydrate were tested using the developed model to verify the prediction robustness. The influence of each component towards the mechanical behaviour of paracetamol varies depending on intermolecular interactions present in the crystal system

    La Siguiente Generaci贸n de Sistemas de Fabricaci贸n (SGSF) trata de dar respuesta a los requerimientos de los nuevos modelos de empresas, en contextos de inteligencia, agilidad y adaptabilidad en un entono global y virtual. La Planificaci贸n de Recursos Empresariales (ERP) con soportes de gesti贸n del producto (PDM) y el ciclo de vida del producto (PLM) proporciona soluciones de gesti贸n empresarial sobre la base de un uso coherente de tecnolog铆as de la informaci贸n para la implantaci贸n en sistemas CIM (Computer-Integrated Manufacturing), con un alto grado de adaptabilidad a la estnictura organizativa deseada. En general, esta implementaci贸n se lleva desarrollando hace tiempo en grandes empresas, siendo menor (casi nula) su extensi贸n a PYMEs. La presente Tesis Doctoral, define y desarrolla una nueva metodolog铆a de implementaci贸n pan la generaci贸n autom谩tica de la informaci贸n en los procesos de negocio que se verifican en empresas con requerimientos adaptados a las necesidades de la SGSF, dentro de los sistemas de gesti贸n de los recursos empresariales (ERP), atendiendo a la influencia del factor humano. La validez del modelo te贸rico de la metodolog铆a mencionada se ha comprobado al implementarlo en una empresa del tipo PYME, del sector de Ingenier铆a. Para el establecimiento del Estado del Arte de este tema se ha dise帽ado y aplicado una metodolog铆a espec铆fica basada en el ciclo de mejora continua de Shewhart/Deming, aplicando las herramientas de b煤squeda y an谩lisis bibliogr谩fico disponibles en la red con acceso a las correspondientes bases de datos
