Cette recherche porte sur la caract�risation morphologique de sols m�diterran�ens et sur la r�alisation de leurs profils coll�s. Men� dans le cadre d'une collaboration entre la Cit� des Sciences et la Facult� des Sciences � Tunis, le travail s'appuie sur une s�lection de sites situ�s le long de l'axe B�ja-Oued Zerga-Mjez El Bab, zone restreinte mais repr�sentative d'une diversit� bioclimatique allant du subhumide au semi-aride. Cette diversit� refl�te les grands processus de p�dogen�se m�diterran�enne, illustr�s par des sols fersiallitiques, des profils calcaires diff�renci�s, des Vertisols et des sols peu �volu�s influenc�s par l'aridit� et l'�rosion. Sur le plan m�thodologique, l'�tude a permis d'�laborer et de tester un protocole op�rationnel de fabrication de monolithes grandeur nature et de mini-profils, ainsi que la conception de supports mus�ographiques adapt�s. Enfin, un texte explicatif bilingue a �t� r�dig� afin d'accompagner ces monolithes et de guider l'observation des caract�res morphologiques cl�s, notamment la couleur, la structure et la texture. Cette d�marche contribue � la valorisation p�dagogique et scientifique des sols tunisiens.

Store Description

**Please note our transit times are from the date of dispatch.** We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first purchase with us, or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
