The Italian Communist Party,local government and the Cold War

The Italian national elections of 18 April 1948 handed power to the Christian Democratic Party. The Italian Communist Party had, however, gained significant municipal control in the local elections of 1946. For the Communists, the local level became the testing ground where administrative practices, political initiatives, social alliances and economic projects were developed. The leaders and the intellectuals worked to outline the cultural framework of a political project which could challenge national politics from town councils. Meanwhile, with a view to making gains in the local elections of 1951–1952, propaganda was used in an attempt to diffuse and proselytise municipal political programmes among different social classes in a divided socioeconomic environment.     

In situ desalination of a granitic column by the electrokinetic method

Desalination of rocks used in monuments is a common strategy to reduce the possibility of deterioration by soluble salt crystallization processes. In the last years, some laboratory studies have demonstrated that the application of electrokinetic techniques allow to achieve higher desalination effectiveness, overcoming most limitations of the traditional methods. However, to our knowledge no studies have been conducted on the effectiveness of this technique for in situ desalination of granite. The present study is aimed at filling this gap. The results of an in situ desalination intervention using electrokinetic methods, on a column highly contaminated with salts are presented. The desalination method was optimized to desalinate large in situ structures, trying to establish the necessary protocols (buffering system, irrigation system, setup, etc.) to obtain results as satisfactory as those obtained in laboratory. The results demonstrated the high effectiveness of this method in terms of total salt extraction and depth of salt extraction. The concentration of anions in the column was decreased by more than 80% after 55 days of treatment. No mineralogical and aesthetic damages on the stone were detected after the treatment, confirming the reliability of this method to be applied in situ on granitic rocks.     

Seismic Assessment of the Lima Cathedral Bell Towers via Kinematic and Nonlinear Static Pushover Analyses

ABSTRACT

The protection of cultural heritage against earthquake induced actions is one of the main challenges the earthquake engineering science and practice are facing. This article presents a seismic assessment study on one of the most ancient colonial buildings present in Peru, the Cathedral of Lima, focusing on its towers. A historical review highlighted how these structures, together with the whole Cathedral, suffered intense damage and partial collapse during previous earthquakes. In order to identify the structure main deficiencies, both linear kinematic analyses and nonlinear static analyses have been performed. Different nonlinear finite element models have been created to evaluate the influence of the adjacent walls. Different load distributions have been compared to evaluate how simplified patterns could provide results close to load distributions taken from a modal analysis of the complex. A simple retrofit strategy, consisting on the introduction of steel ties, has also been studied as a reference. Results show good correlation between kinematic and pushover analyses. The construction, when compared to the requirements of the national code for new buildings, results significantly vulnerable, pointing out the need to accept some structural damage even after seismic retrofit.     

D/Escribiendo lo sagrado: texto y contexto de las dos primeras crónicas marianas de América

Abstract

Mercedarian friar Luis de Cisneros wrote a chronicle on Our Lady of Remedios, first patroness of Mexico City that was published in 1621. Significantly, that same year Augustinian friar Alonso Ramos Gavilán's history on Our Lady of Copacabana, patroness of Peru and Bolivia, was printed in Lima. This paper compares these two founding accounts, not only in their literary structures, but also their patronage, and reception. It also ponders how both cults aimed to integrate both Spaniards and Indigenous peoples under one symbolic figure—the mother of God—as a key element for the consolidation of colonial society, not by coincidence, one of the key goals of the local Church councils that took place in the 1580s.
