Il duomo di San Giorgio a Ragusa-The Cathedral of St. Giorge in Ragusa
2015
Il volume ripercorre la storia di una grande fabbrica dell'architettura siciliana del Settecento, opera dell'architetto Rosario Gagliardi: il duomo di San Giorgio a Ragusa. Le “due raguse” dopo il terremoto del 1693; la chiesa di San Giorgio e il suo architetto; i frammenti della chiesa cinquecentesca: la tribuna di Antonino Gagini; la ricostruzione del duomo dopo il terremoto del 1693; un nuovo progetto per la cupola sono gli argomenti approfonditi dalla ricerca. The volume traces the story of a large religious factory of the eighteenth century in Sicily, a work of the architect Rosario Gagliardi: the cathedral of St. George in Ragusa. The two Raguse after the earthquake of 1693; the churc…
Zu schlesischen Szenarien der Identitätskonstruktion in Szczepan Twardochs Romanen "Morfina" und "Drach"
2020
Because of the dynamic history of Silesia and the related heterogeneity of its population, the problem of national identity in this region was and still is a very sensitive issue. Based on Szczepan Twardoch’s novels Morfina and Drach, the article’s author reconstructs the selected literary identity construction scenarios in the multinational region of Upper Silesia, thus attempting to identify the factors depending on the relevant historical context that affect the development of the sense of national and cultural identity, such as the political climate, individual benefits and interests, continuation of family traditions or the will to dissociate oneself from the past and ancestors. Furthe…
Inconsistencies in the pozzolanic strength activity index (SAI) for silica fume according to EN and ASTM
2014
Published version of an article in the journal: Materials and Structures. Also available from the publisher at: http://dx.doi.org/10.1617/s11527-014-0457-6 Open Access New supplementary cementitious materials claimed to possess pozzolan properties emerge frequently. This development is driven both by economic and environmental pressures. Properties of new materials are compared with those of materials already well known, such as silica fume. Several test methods are standardized for making such comparisons, regulated by both European (EN) and American (ASTM) standards. Standardization indicates that procedures are secured to make comparisons valid and informative. In this article the sensit…
Experimental Investigation on Stiffness and Strength of Single-Lap Z-Pinned Joints in a Laminated CFRP Stress-Ribbon Strip
2016
Carbon fiber-reinforced polymer (carbon-polymer) is an advanced lightweight composite material with high strength and excellent resistance to corrosion and fatigue. Over the past decades, application of fiber-reinforced polymers has been spread from the aerospace to other branches of industry such as automobile and civil engineering. Unidirectional carbon-polymers have a high potential for replacing steel in tensile members. Recently, the first carbonpolymer stress-ribbon bridge has been constructed in Germany. The non-laminated strip-loop carbon-polymer thin strips were used as the load bearing components in this bridge. In comparison with the laminated components, the applied cables are c…
Primitives extraction based on structured-light images
2013
International audience; Geometric attributes such as curvature or surface orientation are additional information of the 3D points obtained after the scanning of an object. In the classic 3D chain, characterized by a sequential structure, these information are determined from the dense point cloud (from a 3D scanner). Then, they are used to reduce the amount of information and allows to obtain a simplified model. In this paper, we investigate the possibility to extract some geometric attributes, directly from 2D images obtained by the camera of a structured-light system.
Towards a Guidance System to Aid in the Dosimetry Calculation of Intraoperative Electron Radiation Therapy
2015
In Intraoperative Electron Radiation Therapy (IOERT), the lack of specific planning tools limits its applicability, the need for accurate dosimetry estimation and application during the therapy being the most critical. Recently, some works have been presented that try to overcome some of the limitations for establishing planning tools, though still an accurate guidance system that tracks, in real-time, the applicator and the patient is needed. In these surgical environments, the acquisition of an accurate 3D shape of the patient’s tumor bed in real-time is of high interest, as current systems make use of a 3D model acquired before the treatment. In this paper, an optical-based system is pre…
Who am I? : the teacher identity construction of student teachers
2015
Opettajaidentiteetti on tutkimusaiheena varsin ajankohtainen ja viime vuosina huomiota on aiempaa enemmän alettu kiinnittää myös opettajaopiskelijoiden ammatti-identiteettiin, sillä tämän rakennusprosessin osatekijät vaikuttavat varsin eri tavoin lopulliseen identiteettiin. Aiempien tutkimusten pohjalta voidaan huomata, että opettajaidentiteetin muodostumisprosessissa on useita eri osatekijöitä, jotka tässä tutkielmassa on jaettu kahteen faktoriryhmään: henkilökohtaisiin ja opettajankoulutuksellisiin faktoreihin. Kirjallisuuskatsauksen perusteella kävi myös ilmi, että useat opettajaopiskelijat kokevat ristiriitaa henkilökohtaisten näkemystensä ja opettajankoulutuksen painotuksen välillä. Tä…
Aristocratic power exaltation between XVI and XVIII centuries in Palermo Area: psychological and symbolic aspects behind suburban villas' constructio…
2014
From ancient times, due to a very favourable climate, and the presence of many pure water sources, the “Golden Valley” surrounding the city of Palermo saw the settlement of an elaborate system of rural farms, “industrial” buildings. During the XVI century, and especially towards the XVIII century, spending some time in the countryside became a real trend for the urbanized Sicilian aristocracy. Thus, such buildings were slowly renewed into sumptuous suburban palaces to exhibit feudal family richness and power as well as to make living in the countryside more pleasant. In western Sicilian area, the architectural typology of the suburban villa is locally characterized by a mixture of the luxur…
Last millennium northern hemisphere summer temperatures from tree rings: Part I: The long term context
2016
Текст статьи не публикуется в открытом доступе в соответствии с политикой журнала. Large-scale millennial length Northern Hemisphere (NH) temperature reconstructions have been progressively improved over the last 20 years as new datasets have been developed. This paper, and its companion (Part II, Anchukaitis et al. in prep), details the latest tree-ring (TR) based NH land air temperature reconstruction from a temporal and spatial perspective. This work is the first product of a consortium called N-TREND (Northern Hemisphere Tree-Ring Network Development) which brings together dendroclimatologists to identify a collective strategy for improving large-scale summer temperature reconstructions…
Quantitative reconstruction of hydroclimate variability over the last 200 kyr in the West Mediterranean
2022
The data show the quantitative annual, winter and summer precipitation reconstructions (mm/yr) from southern Iberian Peninsula for the last ~200,000 years (Camuera et al., 2022), based on the previously published fossil pollen data from the Padul-15-05 lake sediment record (Ramos-Román et al., 2018a, b; Camuera et al., 2019, 2021). The Padul-15-05 record, located in southern Spain (37º00'39''N, 3º36'14''W, 726 masl), was retrieved during summer 2015 from the current edge of the lake using a Rolatec RL-48-L hydraulic percussion coring machine. The quantitative precipitation reconstructions were performed using the performance statistics of the Weighted Averaging-Partial Least Squares (WA-PLS…
