Late-medieval construction site management at the Monastery of Jerónimos in Lisbon

Through the analysis of the exceptional accounting documents of 1517 related to the construction of the Monastery of Jerónimos (Lisbon), this paper discusses the main characteristics of a new model of construction site organization. In the later Middle Ages we can find, among others, two main models of constructing site organization. One, older and more widespread, consisted in a centralized and pyramidal management model. The other, apparently more recent, was based in the existence of several autonomous teams working simultaneously, each one responsible for building a specific part or section of the building. This paper describes and discusses this new organizational model as it was adopted and implemented by João de Castilho (1470–1552) for the construction of the Monastery of Jerónimos in 1517, probably for the first time in Portugal, but with some parallels in other places in Europe.

Organization of construction activity in medieval Portugal: a comparative approach

This paper aims to identify and characterize the organizational models of construction site and building activity in late fifteenth and early sixteenth centuries, through the analysis of specific Portuguese case studies, related with important buildings financed by the royal power. This paper also intends to develop a comparative analysis between those different organizational models, identifying the main features of each one, as well as their similarities and differences. In this sense, we intend to present a comparative analysis between the two main models of organization of the construction site, through a methodology of crossing different types of sources, including written ones, such as books of accounts, but also iconographic and material sources, as well as the buildings and monuments still preserved today. In terms of written sources, the construction site accounting books allow us to study several specific aspects of the construction process, but also allow us to infer the organizational models of the construction activity.

Characterization of late antique and early medieval pottery production of the city of Braga and its territory

The fundamental goal we set ourselves when developing this study is to try to characterize, both technically and formally, ceramics made in the city of Braga and its territory from the initial moments of the Late Antiquity to the Middle Ages. Thus, we will focus on analyzing some own productions that appear attached to the phases of late antique occupation —ceramics of red engobes and late gray—, as well as in the early medieval containers identified in different archaeological interventions practiced in the Braga environment. Concretely, we will analyze the material from various excavations conducted recently at the Theatre in the solar number 20/28 and 36/56 from the Afonso Henriques Street and the former District Hostel as well as the church of São Martinho de Dume.

Os grupos populares nas cidades medievais portuguesas: problematização e inserção no espaço urbano

O objetivo deste estudo visa caracterizar as diferentes categorias sociais que compõem os grupos populares nas cidades medievais portuguesas dos séculos XIV e XV, bem como proceder a uma análise reflexiva acerca do papel destes grupos no desenvolvimento e caracterização do espaço urbano.

Thin films composed of Ag nanoclusters dispersed in TiO2: Influence of composition and thermal annealing on the microstructure and physical responses

Noble metal powders containing gold and silver have been used for many centuries, providing different colours in the windows of the medieval cathedrals and in ancient Roman glasses. Nowadays, the interest in nanocomposite materials containing noble nanoparticles embedded in dielectric matrices is related with their potential use for a wide range of advanced technological applications. They have been proposed for environmental and biological sensing, tailoring colour of functional coatings, or for surface enhanced Raman spectroscopy. Most of these applications rely on the so-called localised surface plasmon resonance absorption, which is governed by the type of the noble metal nanoparticles, their distribution, size and shape and as well as of the dielectric characteristics of the host matrix. The aim of this work is to study the influence of the composition and thermal annealing on the morphological and structural changes of thin films composed of Ag metal clusters embedded in a dielectric TiO2 matrix. Since changes in size, shape and distribution of the clusters are fundamental parameters for tailoring the properties of plasmonic materials, a set of films with different Ag concentrations was prepared. The optical properties and the thermal behaviour of the films were correlated with the structural and morphological changes promoted by annealing. The films were deposited by DC magnetron sputtering and in order to promote the clustering of the Ag nanoparticles the as-deposited samples were subjected to an in-air annealing protocol. It was demonstrated that the clustering of metallic Ag affects the optical response spectrum and the thermal behaviour of the films.

Imagens e representações: o nordeste brasileiro representado entre os finais do século XIX e as primeiras décadas do século XX

Neste artigo desejamos entender como as secas periódicas e seu produto social, o retirante, tornaram-se a representação mais poderosa das paisagens e gentes do Nordeste brasileiro, principalmente quando observamos duas importantes fontes: a imprensa ilustrada do final do século XIX e os manuais escolares. Percebe-se nesses documentos que em ambos a imagem ratifica o discurso civilizatório que fechava os olhos para os problemas sociais. Após análise documental, consideramos a cobertura da seca de 1877-1879 como um marco do nascimento do fotojornalismo no Brasil e do surgimento de uma imprensa que desejava denunciar a calamidade da seca.
