Territorial capital and the economic crisis: The role of spatial effects
2013
Activity-geospatial approach forms methodological basis of the concept of geospatial self-organization of a society as new theoretical paradigm of societal geography (SG) with next main principles: a) Self-organization of society and its key subsystems (economical, social, political, spiritual) in specifically localised natural and societal qualities of geospace (Earth's surface space) forms the process of geospatial self-organization of a society and its results - geospatial interests, processes, systems, structures as societal-geospatial phenomena of different scale (global, regional, local, etc.). So societal processes acquire specific geospatial shapes that combine a geospatial (geograp…
Efektīva arābu valodas apguve mobilajās lietotnēs
2021
Bakalaura darbā ''Efektīva arābu valodas apguve mobilajās lietotnēs'' tiek pētīta arābu valodas apguve mobilajās lietotnēs. Šī darba mērķis ir aplūkot efektīvas arābu valodas apguves metodes, kuras ir iespējams izmantot arābu valodas apguves mobilajās lietotnēs. Mūsdienās ļoti strauji pieaug pieprasījums pēc viedtālruņiem, cilvēki aizvien vairāk izmanto tieši mobilās lietotnes, tāpēc pieaug arī pieprasījums pēc valodas apguves mobilajām lietotnēm. Mobilās lietotnes ir iespējams lietot neatkarīgi no atrašanās vietas un laika, kas ir liels ieguvums valodu apguvē, sevišķi arābu valodas apguvē. Sākotnēji pirmajā nodaļā tiek pētīta valodas apguves metodoloģija, kādu ir iespējams pielāgot arābu v…
Italica (Seville, Spain): use of local marble in Augustan age
2010
This study concerns 51 marble finds made of “Cipollino verde” coming from the ancient city of Italica (north of the modern city of Santiponce, 9 km NW of Seville, Spain), the earliest Roman settlement in Spain, founded in 206 B.C. The aim of this work was to determine their provenance from Greek and Italian quarries or from local quarries worked in the Iberian Peninsula. Thin-section optical microscopy, X-ray powder diffraction, bulk rock chemistry and O, C and Sr stable isotope analyses were carried out. Results were compared with literature data on “Cipollino verde” marbles quarried in southern Euboea (Greece), Apuan Alps (Italy), Almería, Extremoz, Seville (Spain) and Évora (Portugal). T…
A Viscoelastic Model for the Long-Term Deflection of Segmental Prestressed Box Girders
2017
Most of segmental prestressed concrete box girders exhibit excessive multidecade deflections unforeseeable by past and current design codes. To investigate such a behavior, mainly caused by creep and shrinkage phenomena, an effective finite element (FE) formulation is presented in this article. This formulation is developed by invoking the stationarity of an energetic principle for linear viscoelastic problems and relies on the Bazant creep constitutive law. A case study representative of segmental prestressed concrete box girders susceptible to creep is also analyzed in the article, that is, the Colle Isarco viaduct. Its FE model, based on the aforementioned energetic formulation, was succ…
La vegetazione del litorale di Manfria, presso Gela (Sicilia), area soggetta a vincolo archeologico.
2000
The results of a phytosociological investigation about a coastal area of S. Sicily, close to Gela, are presented. The coexistence of several lithological substrata, as well as the particular climatic conditions of this area, gives rise to a noteworthy floristic and vegetational biodiversity. As matter of fact, a set of N. African species are here localized, taking part to peculiar vegetation types, sometimes exclusive of this sicilian coast-stretch. The observed plant communities are represented by psammophilous associations of Cakiletea maritimae, Ammophiletea and Malcolmietalia, salt-marsh vegetation of Sarcocornietea and Phragmito-Magnocericetea, halophilous rupicolous shrublands of Crit…

Role of theN*(1535)resonance and theπ−p→KYamplitudes in the OZI forbiddenπN→ϕNreaction
2008
We study the $\ensuremath{\pi}N\ensuremath{\rightarrow}\ensuremath{\phi}N$ reaction close to the $\ensuremath{\phi}N$ threshold within the chiral unitary approach, by combining the ${\ensuremath{\pi}}^{\ensuremath{-}}p\ensuremath{\rightarrow}{K}^{+}{\ensuremath{\Sigma}}^{\ensuremath{-}},{\ensuremath{\pi}}^{\ensuremath{-}}p\ensuremath{\rightarrow}{K}^{0}{\ensuremath{\Sigma}}^{0}$, and ${\ensuremath{\pi}}^{\ensuremath{-}}p\ensuremath{\rightarrow}{K}^{0}\ensuremath{\Lambda}$ amplitudes with the coupling of \ensuremath{\phi} to the $K$ components of the final states of these reactions via quantum loops. We obtain good agreement with experiment when the dominant ${\ensuremath{\pi}}^{\ensuremath{…
Numerical analysis of masonry structures via interface models
2001
The present paper is devoted to the theoretical formulation and numerical implementation of an interface model suitable to simulate the behavior of mortar joints in masonry structures. The interface laws are formulated in the framework of elasto-plasticity for non-standard materials in order to simulate the softening response which occurs along the decohesion process in presence of shear and tension tractions. A variable material dilatancy parameter is introduced together with a further geometrical dilatancy related to the roughness of contact surfaces after joint fracture. An asperity model is adopted with the aim to describe the evolution of the contact surface shape during the loss of co…
