Colloid-polymer mixtures are subject of intensive research due to their wide range of applicability, for instance in coatings and food-stuffs. This thesis constitutes a fundamental investigation towards a better control over the stability of such suspensions. Through the chapters, different key parameters governing the stability of colloid-polymer mixtures are explored. How the colloid (pigment) shape and the effective polymer-colloid affinity modulate the stability of the suspension are examples of these key parameters. Despise the mostly theoretical results presented, the thesis is written in a format accessible to a broad scientific audience. Some of the equations of state presented might of direct use to experimentalists. Furthermore, new theoretical insights about colloid-polymer mixtures are put forward. These include four-phase coexistences in effective two-component, quantification of depletant partitioning at high colloidal concentrations, multiple re-entrant phase behaviour of the colloidal fluid-solid coexistence, and a condition where polymers are neither depleted nor adsorbed from/to the colloidal surface.

The 18 papers of the book give a comprehensive overview over recent advancesof geodetic research in Latin America. The book is divided in three parts: 1. Geodetic and gravimetric control in Latin America 2. Regional Gravity and Geoid Determination 3. Geodynamic Research Projects The Symposium was held in Vienna, August 1991, at the General Assembly of the International Union of Geodesy and Geophysics.

Existing research on Professional Learning Networks looks at experiences in Europe and North America, with very little attention focused on education systems in the Global South, such as Chile. In 2015 more than 500 School Improvement Networks were created to support state-funded schools across the country with the idea of promoting a culture of collaboration. Although schools are expected to work in networks, they are held to account individually through high-stakes standardized testing and external inspections.This book employs the theoretical framework of collaborative inquiry to guide a mixed method study of fifteen in-depth multi-site case studies and descriptive statistical analysis of a questionnaire answered by 400 networks. The analysis provides evidence of the depth and spread of the knowledge and collaborative practices of these networks. Linking with the literature on Professional Learning Networks, this study highlights how school improvement networks can support the professional capital of principals and curriculum coordinators. The findings of this study are discussed around the issue of network sustainability, stressing the importance of network leadership and conditions of system infrastructure to mobilize network knowledge to schools, increasing the potential impact of school networks to transform schools' practices. By providing a unique inquiry, into an under researched part of the globe in regards to school networks, this book will prove invaluable for academics and practitioners in the areas of mixed method research, educational leadership and comparative education.
