Download or read book Citrus bergamia written by Giovanni Dugo and published by CRC Press. This book was released on 2013-08-23 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Calabria, Italy, where bergamot has been successfully cultivated since the eighteenth century, it is commonly defined as "the prince of the Citrus genus." Written by an international panel of experts from multiple disciplines, Citrus bergamia: Bergamot and its Derivatives represents the most complete treatise on bergamot and its derivatives currently available. Although production of bergamot and its derivatives is comparatively small, its chemical composition and biological properties have been of great scientific interest and the oil is considered essential in many high-quality perfumes. There is also an increased demand for bergamot oil for food flavorings and gastronomy. A tribute to bergamot, Citrus bergamia: Bergamot and its Derivatives covers all aspects of bergamot, from its historical and botanical origins, cultural practices, and transformation technologies to the use of its derivatives, possible contaminations, and biological activity. The book examines the chemical composition of bergamot in peel oils, leaf oils, juice, and fruits, extracted by various techniques—mechanical, distillation, and by supercritical fluids. It covers newly identified classes of compounds, limonoids and statins, describing the identification and assay of natural statins and the pharmacological activities of limonoids. It also discusses bergapten properties and its uses in cosmetics and medicine, as well as the use of bergamot in perfumery and in foods and beverages. The book concludes with a chapter reviewing the available data and global legislative status of bergamot as they relate to the safe use and trade of bergamot products.

Download or read book Catalysis by Transition Metal Sulphides written by RAYBAUD Pascal and published by Editions TECHNIP. This book was released on 2013-03-01 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main application of Transition Metal Sulphides (TMS) as solid catalysts is for production of clean fuels in petroleum refineries. The various feedstocks to be processed all contain more or less sulphur, included in highly stable heteroaromatic molecules. In order to meet the stringent specifications imposed worldwide nowadays on transportation fuels to reduce their environmental impact, catalytic hydroprocessing remains essential. In this process, sulphur is removed as H2S following the reaction between molecular hydrogen and the heteroaromatics. The reaction conditions and reaction medium composition are such that only TMS provide stable catalysts, generally supported on alumina. Both for their fundamental and applied interest, these fascinating systems are still the subject of a very significant research effort, while major advances have been made over the past 30 years, involving innovative preparation routes, sophisticated surface science experiments for characterisation, detailed kinetic and mechanistic studies, and state of the art DFT simulations giving unprecedented insight into the local structure as well as elementary steps at microscopic level. This book aims at providing a complete, comprehensive and updated survey of the field, useful for anyone involved: the student starting a research project, the academic researcher or the refinery engineer willing to deepen their knowledge on the catalytic as well as on the process aspects. 37 specialists from IFP Energies nouvelles, CNRS, or French universities have contributed, reporting a unique synthesis of the last 15 years of research. The preface written by Michèle Breysse, a well known leading scientist who devoted most of her fruitful career to this topic, puts this collective work into a meaningful historical perspective.

Download or read book Electrokinetics Across Disciplines and Continents written by Alexandra B. Ribeiro and published by Springer. This book was released on 2015-08-25 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: The socio-economic activities due to world development are promoting increasing pressures on land, creating competition and conflicts, resulting in suboptimal use of resources. Integrated planning and management of land resources is a top subject of Agenda 21 (managed by FAO), which deals with the cross-sectoral aspects of decision-making for the sustainable use and development of natural resources. This is essential for life-support systems and its productive capacity. In this context, there is a need to find new strategies for sustainable development that links social and economic progress with environmental protection and enhancement. Electrokinetic transport processes (EK) uses a low-level direct current as the “cleaning agent”. EK has been applied to the remediation of polluted soils and other contaminated matrices. It also shows a great potential to be used in different fields, as in saline soil restoration, nutrients recovery from wastes or repair and maintenance of building structures. EK may be an integrated approach for new strategies aiming at sustainable development and to support waste strategies, with worldwide interest. EK can also be coupled with phytoremediation and integrated with nanotechnology, enlarging the scope of its application. The conciliation of the EK in the recovery of secondary resources, remediation and conservation is a multidisciplinary novel approach that opens new technical possibilities for waste minimization, through upgrading of particulate waste products and the recovery of secondary resources for industrial, agricultural or social use.
