  • 9625607141102

  Release : 21 June 2024 - Entry pnb : 23 June 2024

  Patrice Uguet is an independent researcher, engineer by trade. A true realist.
  He looks for explanations and descriptions of still unexplained quantum phenomena.
  We discover with great surprise and great pleasure what entanglement could actually mean.
  He tries to rationally solve the EPR paradox and nonlocality.
  A new fibre theory is slowly born, structured, logical, elegant.
  He brings a new light to the current quantum physics notions that are vague or unexplained: the gravitational force, the expansion accelerating or dark matter.
  His realistic description of time passing by is quite singular.

  Modelling of coagulation processes and removal of non-metallic inclusions at melt's inert gas flushing inside a ladle

  Kaoma Mulenga Michou

  • Connaissances & Savoirs
  • 3612225724622

  Release : 2 September 2016 - Entry pnb : 6 September 2016

  The present work is devoted to optimization based upon physical and mathematical modelling of calcium treatment processes for low-alloy steel grades in Ladle, using Steel Refining Unit (SRU). The widely applicable method of calcium injection into ladle on Steel Refining Unit by means of Flux-Cored Wire (FCW) or the method of silicocalcium blowing-in often requires significant flow rate of calcium containing alloys to ensure the necessary concentration of calcium and sulfur in the finished steel. Methods of mathematical modelling are widely applied for the purpose of improvement of calcium alloys injection modes into ladle. However, mainly heating processes in the ladle are taken into consideration in this connection; meanwhile hydrodynamic processes are accounted only partially. At the same time, interfacial reactions of the metal with steam bubbles play a significant role in the processes of interaction between calcium and supernatant liquid, whereby sulfur and oxygen that are dissolved in steel take part in the reactions described above. Nevertheless, only single quantitative estimates are known for kinetics of mass exchanging processes in the ladle. Finally, efficiency of calcium treatment depends on chemical composition of steel. Probability of low-melting calcium aluminates formation, which ensure improvement of pouring capacity, depends not only on the frequently used proportion of [Ca] to [Al], but also on conditions of steel oxidation and sulfur content in the steel. Therefore, optimization of injection modes for calcium containing alloys based on the thermodynamic and kinetic analysis of steel deoxidation and modification conditions, as well as on the mathematical modelling of mass exchanging processes, represents a crucial scientific and technical challenge of nowadays.

  Nuclear medicine ; radioactivity for diagnosis and therapy

  Richard Zimmermann

  • EDP Sciences
  • HORS COLLECTION
  • 9782759815814

  Release : 2 January 2013 - Entry pnb : 21 February 2014

  Nuclear medicine is a specialized medical field based on the application of radiopharmaceuticals, i.e. drugs associated to radioactivity, for diagnosis or therapeutic purposes. In the past fifty years, nuclear medicine has progressed in such a way that it is now a major tool in hospitals. Nowadays, this technology enables to better detect, observe and describe diseases, and also to improve treatments. Cancer therapy is the main application of this speciality. Once injected to the patient, the radiopharmaceutical drug aims selectively at the tumoral cells, including the metastases, settles there and emits radiation. Depending on the type of radiation, the drug will either help to identify the cells or to destroy them. Recent breakthroughs in this technology bring new perspectives to oncology, haematology and neurology.
  At the same time, since the beginning of the 21st century nuclear medicine has also benefited from a double revolution in terms of imaging technology. On the one hand, the Positron Emission Tomography (PET) made a real impact with a polyvalent imaging drug called FDG. On the other hand, a new tool combining functional and morphological imaging (PET-CT) was very recently made available to the medical community. This scientific book aims to introduce nuclear medicine to a larger audience, pointing out, among other things, the difficulties both physicians and patients meet when trying to access new technologies. There are still some issues to overcome, but recent scientific breakthroughs bring great hopes for patients in the near future. Read more Close

  Atom movements ; diffusion and mass transport in solids

  Jean Philibert

  • EDP Sciences
  • 9782759813438

  Release : 2 January 2013 - Entry pnb : 21 February 2014

  The present book is the result of diverse courses on diffusion. It is intended to give as complete an overview as possible of diffusion in solid media, while relating the process of diffusion to both their physical bases and their applications. A series of a real situations is covered in this account, from self-diffusion of radiotracers to the more complex cases of mass flow under chemical or thermal gradients or under electric fields, or diffusion in structures of lower dimensionality (surfaces and interfaces).
  In all these analyses, no category of materials was favored; metals, ionic crystals, oxydes, and semiconductors all had their turn. Only polymers were not specifically touched. One chapter is specifically devoted to techniques for studying diffusion, including methods of numerical simulation, and a last and long chapter gives a number of metallurgical phenomena in which diffusion plays a fundamental role.

  Thermodynamics and phase tranformations ; the selected works of Mats Hillert

  John Agren, Yves Bréchet, Christopher Hutchinson, Gary Purdy, Jean Philibert

  • EDP Sciences
  • Sciences des matériaux
  • 9782759815852

  Release : 3 December 2012 - Entry pnb : 21 February 2014

  For more than a half-century, Mats Hillert has contributed greatly to the Science of Materials. He is widely known and respected as an innovator and educator, a scientist with an enormous breadth of interest and depth of insight. The difficult choice of twenty-four papers from a publication list of more than three hundred was carried out in consultation with him. He also suggested or approved names of those scientists who would be invited to write brief introductions to each of the papers.
  
  A brief reading of the topics of the selected papers and their introductions reveals something of their range and depth. Several early selections - including internal reports of the Swedish Institute for Metal Research, published here in their original shape - contained seminal material that established Mats as a leading figure in the study of phase transformations in solids. Others established his presence in the areas of solidification and computational thermodynamics.
  
  This volume represents a judicious sampling only of Mats Hillert's extensive body of work; it is necessarily incomplete, but it is hoped and expected that it will prove useful to students of Material Science and Engineering at all levels, and that it will inspire the further study and appreciation of his many contributions.
