• Sommario/riassunto: Clay minerals are one of the most important groups of minerals that destroy permeability in sandstones. However, they also react with drilling and completion fluids and induce fines migration during hydrocarbon production. They are a very complex family of minerals that are routinely intergrown with each other, contain a wide range of solid solutions and form by a variety of processes under a wide range temperatures and rock and fluid compositions. <br /> In this volume, clay minerals in sandstones are reviewed in terms of their mineralogy and general occurrence, their stable and radiogenic i

• Sommario/riassunto: Today more and more ethnically, culturally, and linguistically diverse students enroll in our college and university courses. These diverse, multilingual students enrich our campuses and at the same time present challenges. Who are these students? What skills do these diverse students need to be successful in college? How can faculty help them succeed? For faculty in all disciplines seeking answers to these questions, this is an essential book. This text provides practical advice on how to assist these students with academic tasks and how to help them to succeed in the academy.
