The sestiere of San Polo : a cross section of Venetian society in the second half of the fifteenth century
No full textThis thesis seeks to add to our understanding of Venetian
society in the latter half of the fifteenth century by
offering a new approach: an in-depth study of one of
Venice's six districts (sestier1). My researches
concentrated on the sestiere of San Polo, which embraced
the Rialto. My intention in narrowing the focus of analysis
is to reveal a cross-section of society. Fundamental to this
inquiry is to discover the identity of this sestiere; to
explore its little known social profile, trades and
solidarities and to sharpen the images of its urban fabric.
At the same time, it is an investigation into the
significance and role of neighbourhood and local loyalties
in Renaissance Venice. The opening chapter discusses the
changing topography of San Polo and its definition over the
following three centuries. Boundaries were blurred; parish
disputes document how and why they were changed. Chapter Two
introduces the three social orders recognised by
contemporaries (patriciate, citizenry and artisans), tracing
the sharpening of hierarchy, the growing cohesion of the
cittadini originarii and the emergence of poorer
neighbourhoods towards the city's margins. Chapter Three
investigates noble and cittadini families in San Polo,
through a number of detailed case studies. A complex and
varied picture emerged, in which family structures and
residential patterns amongst the nobility did not conform to
rigid models. Chapter Four attempts to flesh out a
collective portrait of the "little people", beginning with
Rialto. Chapters Five and Six discuss property; initially
through a massive survey after the Rialto fire (1514);
Quattrocento sources are then used to examine property at
Rialto, domestic housing, building activity and renting. The
final chapter deals with neighbourhood, concluding that the
sestiere was not an effective social unit and that local
loyalties formed part of complex and changing webs of
allegiance
The mechanical power output in water polo game: a case report
No full textIn water polo some authors have assessed the physical requirements of the game by analysing physiological indices or considering the distances covered at various swimming speeds in the match. In this work, the passive drag was measured in “best glide” (Swim) and “head-up” (Wp) position in a water polo player. The active drag was estimated indirectly from the passive drag. The mechanical power required to play a match is calculated on the data of a match model obtained from a video analysis in a series of international water polo matches. The average mechanical power of a water polo match in the Swim model was 150489 J/2400 s= 62.70 W, while in WP model it was 481375 J/2400 s= 200.57 W. The mechanical power required in water polo players could be more than three-fold higher mechanical power required in water polo players could be more than that required for freestyle swimming at the same velocities
"O, Małgorzato, będzie na bogato". Dynamika swojskości i światowości w ikonografii wideoklipów disco polo
No full textThe author traces the phenomenon of disco polo music and analyses the video clips of popular musicians from the 90’s (Shazza and Boys), comparing them with modern visual representations (Mig and Niecik), following the idea that what made and still makes this music genre popular is the specific tension between familiarity and wordliness.The author traces the phenomenon of disco polo music and analyses the video clips of popular musicians from the 90’s (Shazza and Boys), comparing them with modern visual representations (Mig and Niecik), following the idea that what made and still makes this music genre popular is the specific tension between familiarity and wordliness
Solar Radiation and Daylighting Assessment Using the Sky-view Factor (SVF) Analysis as Method to Evaluate Urban Planning Densification Policies Impacts
No full textAbstractThis study identifies and proposes simple methods to assess solar radiation, daylighting availability and Sky-View Factor (SVF) modification, in complex urban environment. Numerical methods and 3D simulation software are combined with photo processing methods using digital cameras with special mirrors to project the hemispherical environment onto a circular image. This methodology has been applied to a real case study in Switzerland that is undergoing a very fast urban densification process, where urban planning strategies will determine significantly the possibility to relish solar irradiation in buildings. This paper analyzed the particularities of different urban scenarios considering the effects of urban densification planning strategies on existing buildings, in particular historical protected buildings
The Energy Performance Evaluation of Buildings in an Evolving Built Environment: An Operative Methodology
No full textAbstractThe paper is based on a case study in Switzerland, where the Cantonal Director Plan, expected for the next years, will change the urban density. The plan allows raising from three and four floors the height of the existing buildings now separated by streets that are quite narrow, to get over up to eight floors, without modifying the width of street. A case study located in Paradiso municipality, part of Lugano's city (CH) is used to understand and quantify the impact of the future buildings on the energy performance of historical heritage buildings. The building adopted as case study is protected as cultural monument by the new Master Plan and listed in the sectorial regulations for the landscape. However, this building as others in the area is strongly influenced by the new changes in act, due to the New Master Plan, in term of solar availability and thus energy demand. The actual urban density scenario is compared to the future one to evaluate through dynamic energy simulation the change affecting the building considering the energy and economic aspects
Kinesis 'versus' logos en la filosofía de Leonardo Polo
No full textKinesis versus logos in Leonardo Polo´s philosophy. Kinesis and praxis are analogous concepts in Aristotle. Although Leonardo Polo’s philosophy is right in pointing the differences between these concepts, the article demonstrates that beyond their opposition these terms refer to an analogous pros en: energeia. The author explains Leonardo Polo’s ne-cessity to point the difference and Aristotle’s concern for poin-ting their similarity
Mitotic Exit Function of Polo-like Kinase Cdc5 Is Dependent on Sequential Activation by Cdk1
No full textSummaryTo complete mitosis, Saccharomyces cerevisiae needs to activate the mitotic phosphatase Cdc14. Two pathways contribute to Cdc14 regulation: FEAR (Cdc14 early anaphase release) and MEN (mitotic exit network). Cdc5 polo-like kinase was found to be an important mitotic exit component. However, its specific role in mitotic exit regulation and its involvement in Cdc14 release remain unclear. Here, we provide insight into the mechanism by which Cdc5 contributes to the timely release of Cdc14. Our genetic and biochemical data indicate that Cdc5 acts in parallel with MEN during anaphase. This MEN-independent Cdc5 function requires active separase and activation by Cdk1-dependent phosphorylation. Cdk1 first phosphorylates Cdc5 to activate it in early anaphase, and then, in late anaphase, further phosphorylation of Cdc5 by Cdk1 is needed to promote its MEN-related functions
L'Italia settentrionale. Le contaminazioni del Gotico
No full textL’articolo ripercorre, sulla base di un disegno geografico e cronologico, i caratteri e le vicende dell’arte gotica nell’Italia settentrionale, partendo dal Piemonte, dove il gotico si diffonde precocemente in ambito architettonico (basti pensare al Sant’Andrea di Vercelli, eretto nel 1219-27), per poi investire anche il campo della pittura, con esiti che trapassano anche in area lombarda. Qui gli orientamenti gotici, introdotti dai cantieri cistercensi, assumono in ambito architettonico caratteri peculiari che si riverberano per tutto il XIV secolo sia nel campo dell’edilizia religiosa, sia in quello dell’architettura civile e fortiificata, che trova nei castelli viscontei la sua espressione più compiuta. La costruzione e la decorazione scultorea di queste fabbriche è monopolizzata per tutto il Trecento dai così detti “maestri campionasi”, tra i quali emergono, in ambito scultoreo, personalità di assoluto rilievo, come Ugo e Giovanni da Campione, Matteo da Campione e Bonino da Campione, la cui attività, segnata da forti influssi toscani, oltrepassa l’area lombarda, per investire anche centri come Verona e Padova. Influssi toscani trovano riscontro anche in pittura, specie a partire dall’età di Azzone Visconti, ma vengono comunque interpretati in termini originali. La stessa originalità che si evidenzia nella produzione artistica dei domini scaligeri, dove operano artisti come Tommaso da Modena e Altichiero da Zevio
"Le Puglie per il viaggiatore incantato": immagini pasoliniane
No full textIl saggio analizza le pagine di Pier Polo Pasolini dedicate alla Puglia: si tratta di alcuni articoli dei primi anni Cinquanta e di una parte del reportage del 1959 "La lunga strada di sabbia". Lo scrittore apprezza particolarmente il paesaggio pugliese, che torna a visitare quando si accinge a girare "Il Vangelo secondo Matteo", alcune parti del quale saranno collocate a Massafra e in altri luoghi vicini, ritenuti più vicini all’atmosfera degli spazi evocati nel testo sacro rispetto alla Palestina
Corrosion of concrete structures due to climate change
No full textConcrete is clearly one of the most predominant-used material in both residential and non-residential structures across Europe (Peled and Fishman, 2021). A reinforced concrete (RC) structure is expected to satisfy criteria for serviceability, structural integrity, and stability over its designed operational lifespan, without significant loss of utility or excessive unforeseen maintenance (for general requirements see also EN 1990). Comprehending the degradation mechanisms that impact these structures is essential for accurately estimating their service life and formulating cost-effective maintenance strategies. The main mechanisms responsible for concrete degradation include corrosion caused by carbonation and the presence of chloride ions, freeze-thaw cycles, sulphate attack and erosion due to high-velocity water flow, ice, or wind-blown sand.Integral Design & Managemen
