For a more encompassing and stimulating picture of Modernism - seen as a movement of the 20th century, a broad spectrum of work across many countries - we must explore its diversity. Portuguese Modernism manifested itself both in visual art and in literature, and made a vigorous contribution to this time of profound cultural change. Indeed, the sociocultural transformations that marked the early 20th century in Portugal are still current. This volume provides a critical guide for students and teachers, contributed to by an array of scholars with unparalleled knowledge of the period, its artists and its writers. Steffen Dix is Research Fellow at the Institute of Social Science, University of Lisbon; Jeronimo Pizarro is Research Fellow at the Linguistics Centre, University of Lisbon.

This book presents a number of essays written by specialists in various fields that include literary criticism, linguistics, sociology, history and art criticism. It offers an excellent overview of Portuguese modernism in a current, challenging and encompassing manner.

Optical anisotropy effects can occur in building envelopes made of tempered glass. The visual effect has been neglected in the evaluation of the building product and increasingly leads to disputes between the parties involved. This thesis extends the state of knowledge on the cause and perception of optical anisotropic effects and presents a concept for measuring and evaluating them in flat monolithic tempered architectural glass. Initially, an overview and description of current photoelastic measurement methods are given, and the accuracy of the used measurement setups is verified for the first time. The experimental basis for the concept is formed by extensive full-field retardation measurements in the laboratory and field studies of the maximum visibility of the anisotropy effects in an outdoor test rig with accompanying polarization measurements of the sky. Various glass types, geometries, and tempering levels are selected based on typically used products, and their influence on the resulting retardation image is investigated. Determining a correlation of the retardation images with the reflection images of selected test specimens in the outdoor test rig complements the experiments. Based on this, digital evaluation methods are presented, further developed, and applied to the measured retardation images. From the critical analysis of these results, limit values for different anisotropy quality classes are derived, and the concept is complemented. With the implementation of the evaluation methods and the limit values in commercial anisotropy scanners, the quality of each glass pane can be determined directly after tempering in the future. By choosing the highest quality class A, it will be possible in the future to significantly reduce anisotropy effects in constructions made of tempered glass panes.
