L'ÉMOTION ET LA RAISON : L'EFFET MODÉRATEUR DU GENRE SUR LE COMPORTEMENT D'ACHAT EN LIGNE
2018
RESUMEN: A pesar de la evidencia existente en torno a las diferencias entre mujeres y hombres en los procesos de toma de decisiones, así como en la adopción de la tecnología, la investigación llevada a cabo hasta la fecha no ha sido concluyente. El objetivo de este trabajo es estudiar las intenciones comportamentales de los consumidores según su género en los intercambios comerciales B2c. En este sentido, se propone identificar cómo el valor funcional -representando el raciocinio del consumidor-, el valor simbólico -representando la motivación emocional- y la confianza actúan como antecedentes de la intención de compra en el canal online. A partir de los resultados derivados de una investig…

La resistenza di interfaccia calcestruzzo poroso-terreni a grana fina per il consolidamento di pendii mediante trincee drenanti profonde
2022
Le trincee drenanti profonde rappresentano uno dei metodi più efficaci per la mitigazione del rischio da frana, in pendii con falda idrica. Esse sono realizzate mediante pannelli o pali secanti. Il riempimento è costituito di calcestruzzo poroso o materiale granulare. Se le trincee sono adeguatamente “innestate” nel terreno stabile e il materiale di riempimento ha sufficiente resistenza e rigidezza come il calcestruzzo poroso, si ha ulteriore in-cremento di resistenza a taglio per effetto shear keys, oltre a quello derivante dalla riduzione delle pressioni in-terstiziali. L’incremento di resistenza è dovuto sia alla resistenza all’interfaccia calcestruzzo–terreni sia a quella intrinseca del…
Vademecum lektora języka polskiego na Słowacji i w Czechach - pomoce dydaktyczne
2017
The purpose of this study is to describe the specificity of teaching Polish as a foreign language to Slovaks and Czechs (including the advantages and disadvantages resulting from language transfer), and to present the available teaching materials for Slovak and Czech students. The text includes an evaluation of the practical utility of different PFL textbooks designed for these groups and presents some suggestions for new teaching Solutions, such as the textbooks created at the Comenius University in Bratislava.
ON SOME GENERALIZATION OF SMOOTHING PROBLEMS
2015
The paper deals with the generalized smoothing problem in abstract Hilbert spaces. This generalized problem involves particular cases such as the interpolating problem, the smoothing problem with weights, the smoothing problem with obstacles, the problem on splines in convex sets and others. The theorem on the existence and characterization of a solution of the generalized problem is proved. It is shown how the theorem gives already known theorems in special cases as well as some new results.
Aerosol and droplet generation during intubation and normal breathing: a simulation study
2021
COVID-19 pacientu aprūpē var būt nepieciešama intubācija, kas ir aerosola un pilienu ģenerējoša procedūra, šādi palielinot vīrusa izplatības iespēju. Intubāciju ieteicams veikt pieredzējušam speciālistam labākai balss saišu vizualizācijai un ātrākai procedūras veikšanai, kas tādējādi samazinātu aerosola un pilienu veidošanās laiku. Šī pētījuma mērķis ir izpētīt pilienu un aerosola daudzumu, kas rodas normālas elpošanas laikā, kā arī salīdzināt intubācijas ilgumu, kontakta kontamināciju, pilienu izplatību un aerosolizāciju, kas rodas intubāciju veicot pieredzējušam enesteziologan un anestezioloģijas pirmā gada rezidentam. Metodes Eksperimentā I AMBU elpināšanas maiss tika piestiprināts manek…
Partial data inverse problems and simultaneous recovery of boundary and coefficients for semilinear elliptic equations
2021
We study various partial data inverse boundary value problems for the semilinear elliptic equation $\Delta u+ a(x,u)=0$ in a domain in $\mathbb R^n$ by using the higher order linearization technique introduced in [LLS 19, FO19]. We show that the Dirichlet-to-Neumann map of the above equation determines the Taylor series of $a(x,z)$ at $z=0$ under general assumptions on $a(x,z)$. The determination of the Taylor series can be done in parallel with the detection of an unknown cavity inside the domain or an unknown part of the boundary of the domain. The method relies on the solution of the linearized partial data Calder\'on problem [FKSU09], and implies the solution of partial data problems fo…
Pressure-Induced Deformation of Pillar-Type Profiled Membranes and Its Effects on Flow and Mass Transfer
2019
In electro-membrane processes, a pressure difference may arise between solutions flowing in alternate channels. This transmembrane pressure (TMP) causes a deformation of the membranes and of the fluid compartments. This, in turn, affects pressure losses and mass transfer rates with respect to undeformed conditions and may result in uneven flow rate and mass flux distributions. These phenomena were analyzed here for round pillar-type profiled membranes by integrated mechanical and fluid dynamics simulations. The analysis involved three steps: (1) A conservatively large value of TMP was imposed, and mechanical simulations were performed to identify the geometry with the minimum pillar density…
A hierarchical model for novel schemes of electrodialysis desalination
2019
Abstract A new hierarchical model for the electrodialysis (ED) process is presented. The model has been implemented into gPROMs Modelbuilder (PSE), allowing the development of a distributed-parameters simulation tool that combines the effectiveness of a semi-empirical modelling approach to the flexibility of a layered arrangement of modelling scales. Thanks to its structure, the tool makes possible the simulation of many different and complex layouts, requiring only membrane properties as input parameters (e.g. membrane resistance or salt and water permeability). The model has been validated against original experimental data obtained from a lab scale ED test rig. Simulation results concern…
12C ion beam dose distribution in presence of medium inhomogeneities: comparison between different measurements and simulations with the treatment pl…
2012
Heavy-ions beams offer several advantages compared to other radiation such as low lateral scattering and high biological effectiveness (RBE) in the Bragg peak region, making them particularly attractive for the treatment of radio-resistant tumours localized close to organs at risk [1]. The extension of ion therapy to new clinical cases requires the exploitation of a dedicated treatment planning system (TPS) based on the existing version of TRiP98 [2,3], established TPS for carbon ions. The theoretical models and experimental databases included in TRiP98 are presently mainly based on measurements in water. This approximation can be applied successfully to reproduce many biological tissues wi…
