Flat Roofs

Reservoir, or water-collecting roofs present greater thermal inertia than inverted flat roofs due to the mass of water they contain. This feature gives them better thermal performance and leads to greater stability in the indoor air temperature Ti and the wall surface temperatures. In the summer, they can dampen the effect of solar radiation and regulate external thermal loads thanks to their greater effusivity and thermal capacity. This research compares the thermal behavior of the roofs of two buildings located in Alicante on the Spanish Mediterranean coast: a loft flat in the city center and a water-covered roof in the Museum of the University of Alicante (MUA). Values for effusivity, diffusivity, thermal capacity, decrement factor, time lag and internal, as well as external thermal admittance were obtained. After monitoring both roofs during 2014, behavior simulations were performed in Design Builder using 6 different scenarios reflecting different combinations in both buildings of water-covered, inverted and conventional roofs and marble or terrazzo paving. The water-covered roof led to a higher decrement factor and time lag, as well as to a reduction of annual energy demands between 8.86% and 9.03%.

Bodin arrived in Toulouse c.1550, a brief account of the economy, social composition, and governmental institutions of which opens the chapter. There follow comments on its cultural life and identification of its leading citizenry, with remarks on the treatment of alleged religious dissidents by the city itself, and especially on discordant intellectual influences at work in the University, most notably the Law Faculty and the modes of teaching there. The chapter’s second part reviews Bodin’s translation and edition of the Greek poem Cynegetica by Oppian ‘of Cilicia’, assessing the quality of his editorial work, the extent to which allegations of plagiarism levelled against him were valid, and the nature and merits of his translation. The third section recounts contemporary wrangling over educational provision in Toulouse and examines the Oratio in which Bodin argued the case for humanist-style educational provision by means of a reconstituted college there.

A substantial share of the building sector in global energy demand has attracted scholars to focus on the energy efficiency of the building sector. The building’s energy consumption has been projected to increase due to mass urbanization, high living comfort standards, and, more importantly, climate change. While climate change has potential impacts on the rate of energy consumption in buildings, several studies have shown that these impacts differ from one region to another. In response, this paper aimed to investigate the impact of climate change on the heating and cooling energy demands of buildings as influential variables in building energy consumption in the city of Poznan, Poland. In this sense, through the statistical downscaling method and considering the most recent Typical Meteorological Year (2004–2018) as the baseline, the future weather data for 2050 and 2080 of the city of Poznan were produced according to the HadCM3 and A2 GHG scenario. These generated files were then used to simulate the energy demands in 16 building prototypes of the ASHRAE 90.1 standard. The results indicate an average increase in cooling load and a decrease in heating load at 135% and 40% , respectively, by 2080. Due to the higher share of heating load, the total thermal load of the buildings decreased within the study period. Therefore, while the total thermal load is currently under the decrease, to avoid its rise in the future, serious measures should be taken to control the increased cooling demand and, consequently, thermal load and GHG emissions.

In this article, Silvija Jestrovic introduces the notion of spatial inter-performativity to discuss theatre's relationship to actual political and cultural spaces. Focusing on the Berlin of the 1920s in performances of Brecht and Piscator, then on a street procession of the Générik Vapeur troupe that took place in Belgrade in 1994, she examines how theatrical and political spaces refer to and transform one another. Silvija Jestrovic was a SSHRC postdoctoral fellow at York University in Toronto, and has recently taken up an appointment in the School of Theatre Studies at the University of Warwick. She is currently working on a book-length project entitled Avant-Garde and the City.

The Welfare State

In 1983 we organized a conference on “Questioning the Welfare State and the Rise of the City” at the University of Paris, Nanterre. About a hundred persons attended, including many French social scientists and political activists. Significant support came from the new French Socialist government. Yet with Socialism in power since 1981, it was clear that the old Socialist ideas were being questioned inside and outside the Party and government—especially in the important decentralization reforms. There was eager interest in better ways to deliver welfare state services at the local level.

<p>The Altstadtring-Tunnel is one of the essential east-west traffic routes in the city center of Munich and was constructed in the late 1960s. Segment 34 of the tunnel was built directly underneath the existing Prince-Carl- Palais, a historic building from 1804. Therefore 15 pre-stressed concrete girders with an effective depth of</p><p>3.5 m and a maximum span of up to 30 m were built which now form the tunnel roof slab. These girders were pre-stressed with steel nowadays well known for stress corrosion cracking. A recalculation of the slab showed that no ductile failure can be guaranteed in case of a progressive rupture of the tendons. Therefore, a concept for strengthening the slab was developed using concrete screw anchors as post installed bending and shear reinforcement. The concrete screw anchors are normally installed as anchoring elements in cracked and non- cracked concrete and are available with diameters up to 22 mm. Developing this concept further, it is straight forward to use these anchoring elements as post-installed reinforcement in existing concrete structures. This new strengthening system was developed at the University of Innsbruck in the last few years and can fulfill the special requirements of this project, such as installation of the strengthening system from underneath the tunnel slab during ongoing use of the structure. High strength steel with diameters of up to 63.5 mm will be used as post-installed bending reinforcement covered with a new shotcrete layer on the underside of the tunnel slab. In total 59.3 tons of new flexural reinforcement and 7199 concrete screws for strengthening the shear capacity of the girders will be used to ensure a ductile failure of the tunnel slab. The on-site work started in March 2019 and is expected to take two years to complete.</p>

This reflection is based on the notes recorded in a field journal and its objective is to systematize the experience acquired as an educator in the Diagnostic and Derivation Center, operated by the University of Antioquia through the Grow with Dignity Project (Zuluaga, 2015-2016), attached to the Unit of Childhood, in the City of Medellín, Colombia, whose purpose is the immediate protection of children and adolescents in situations of violation of rights. We will analyze, here, the power relations that are established within the adult-centered paradigm; we will reveal the genesis of child abuse in these relations, and we will see how these normalized practices in the upbringing of children by their families of origin permeate the protection institutions that have been created to accomplish processes of restoration of rights. When unequal power relationships are instituted and legitimated within the family, the hegemony of adults over childhood is consolidated, and the latter ends up being objectified, like this normalizing their abuse. These relational paradigms are also susceptible to reproduction in educational institutions, including those aimed at the protection of children in situations of violation of rights. We will suggest a proposal called humanized reeducation, which is indicated for group leadership in protection institutions, a task entrusted to educators.
