• Confronté à l'un des spectacles les plus beaux du monde - Istanbul et le Bosphore, vus du sommet de la tour de Galata - Georges Cohen éprouve une soudaine nostalgie pour son "paradis perdu", Tunis, et la petite vie, humble et simple, qu'il a vécue au sein d'une communauté juive inconsciente des bouleversements qui allaient l'affecter. Il décide alors de raconter "le banal, le quotidien" afin de conserver au moins la mémoire de ce qui fut et n'est plus. La Tunisie qu'il décrit est "sa" Tunisie. Elle est différente de celle d'un petit Arabe de Bab Souika, d'un petit Français, fils de fonctionnaire ou de colon, d'un Italien de la "Piccola Sicilia". C'est celle d'un enfant juif, vivant à Tunis, dans un quartier qui n'est ni la Hara, ni la deuxième porte du Belvédère. Les vingt ans qui occupent ce récit seront traversés par deux événements majeurs : d'une part l'occupation allemande, en 42-43, d'autre part la lutte pour l'Indépendance et la fin du Protectorat. L'auteur essaye de comprendre et d'expliquer un processus au terme duquel des communautés qui coexistaient harmonieusement, formant une mosaïque de peuples, de races, de religions, de coutumes, de traditions, ont pris le chemin du départ. Il s'intéresse, dans ce récit, à celle qu'il connaît le mieux, la sienne.

  • Ce livre, compagnon de Le métabolisme cellulaire et sa régulation du même auteur et de la même collection, donne les bases physiologiques et moléculaires d'une étude rationnelle des mécanismes par lesquels la cellule microbienne arrive à s'adapter avec succès aux changements que peut subir son environnement.

    The present work emphasises the importance of microbial physiology, biochemistry, genetics and evolu­tion in the study of biosynthesis. It takes into account the considerable advances made in the field in the last twenty years by the introduction of gene cloning and sequencing and by the exponential development of physical methods such as X-ray crystallography of proteins.
    After dealing with the kinetics of bacterial growth and the most recent developments in the mechanisms of cellular permeability, a chapter treats the phenomenon of allostery, indispensable for the understanding of many phenomena described in the rest of the book.

  • Transport systems are facing an impossible dilemma: satisfy an increasing demand for mobility of people and goods, while decreasing their fossil-energy requirements and preserving the environment. Additionally, transport has an opportunity to evolve in a changing world, with new services, technologies but also new requirements (fast delivery, reliability, improved accessibility). The subject of traffic is organized into two separate but complementary volumes: Volume 3 on Traffic Management and Volume 4 on Traffic Safety. Traffic Management, Volume 3 of the `Research for Innovative Transports' Set, presents a collection of updated papers from the TRA 2014 Conference, highlighting the diversity of research in this field. Theoretical chapters and practical case studies address topics such as cooperative systems, the global approach in modeling, road and railway traffic management, information systems and impact assessment.

  • Legal, Tax and Accounting Strategies for the Canadian Real Estate Investor begins and ends with the premise that buying property in Canada can be a smart, safe and successful way to invest your money. However, like most things in life, success requires hard work. You need to do your homework, understand what you are buying, and know the pros and cons of various decisions. Most importantly, you also need to know how to structure and maintain your investment. That's where we come in. Experience is a good teacher-but its lessons can be nasty and, in the real estate business, mistakes can cost you big bucks. Our goal with this book is to help you do it right-the first time. Rest assured that this book covers a vast range of topics and you're going to appreciate its breadth and depth if you're wondering about things like whether: You should opt for a sole proprietorship versus a partnership or corporate ownership strategy. There are things you can do to manage the way HST impacts your real estate investment business. You need information about the tax implications of a real estate disposition. You can change your bookkeeping system to better meet your needs and those of your accountant. Who Are We? This book was written by two individuals whose collective experience in helping Canadians make wise property investment decisions spans several decades. Steve Cohen is a securities lawyer with a great deal of experience in the real estate sector. George Dube is a chartered accountant whose knowledge is based on many years of helping clients with their property buying needs. Both Steve and George are real estate investors themselves. Working from this foundation, we have put together the definitive guide on how to build a successful real estate portfolio in Canada from a legal, tax and accounting perspective.
