Lo scambio e il legame

2009

Lo studio analizza il modello economico dello scambio economico e finanziario, nel mondo contemporaneo, visto come modello relazionale che esige la libertà e l'interruzione dei legami affettivi come importante requisito per progredire nell'aderenza al modello liberista. Si mostra anche come il paradigma del dono, (dare, ricevere e ricambiare) rappresenta un momento resistenziale nella realtà odierna per mantenere il legame, interpersonale e sociale.

L'incoscienza del dono

2003

L'autore mostra come il dono sospende la coscienza, il principio di identità e quello di ragion sufficiente.

ESSERE-L'AMATO: DONO E GRATITUDINE D'ESSERE

2013

La conoscenza riflessa di sé è un dono; questo permette di giustificare una ontologia della persona come essere-l'amata. L'esistenza, in questa prospettiva, è vista ed intesa come un dono offerto per un compito responsabile

Przeszczepy narządowe w okresie epidemii COVID-19

2020

Epidemia COVID-19 zmieniła podejście do kwalifikacji dawców i biorców przeszczepów narządowych. Kwalifikacja następuje po obowiązkowym wykonaniu tomografii komputerowej płuc i testu RT-PCR na obecność wirusa, w wyniku indywidualnej oceny korzyści i ryzyka zakażenia. W bardziej odległym okresie od transplantacji na ciężkość objawów w większym stopniu niż leczenie immunosupresyjne wpływają zaawansowany wiek i współchorobowości. Pierwszym krokiem w redukcji leczenia immunosupresyjnego u biorców przeszczepów narządowych jest odstawienie leku antyproliferacyjnego z pozostawieniem inhibitora kalcyneuryny i steroidów. Terapia immunosupresyjna znamiennie wydłuża czas eliminacji wirusa, ale może ogr…

Ab initio calculations of Nb doped SrTiO3

2010

We present and discuss the results of the large scale Hartree–Fock calculations of Nb impurities substituting for Ti ions in SrTiO3 using ab initio computer code CRYSTAL and several supercells containing up to 135 atoms. The local structure optimisation, the electronic charge redistribution, chemical bond covalence and the band-structure changes induced by the defect are analysed. According to the results of our calculations, Nb is a shallow donor; six nearest O ions are slightly displaced outwards from the Nb ion. The calculated bond population between nearest Ti and O ions (64 me) is much larger than that between Nb and O ions (8 me), since Nb impurity is more ionic than the host Ti.

Multiobjective muffler shape optimization with hybrid acoustics modelling

2010

Shape optimization of a duct system with respect to sound transmission loss is considered. The objective of optimization is to maximize the sound transmission loss at multiple frequency ranges simultaneously by adjusting the shape of a reactive muffler component. The noise reduction problem is formulated as a multiobjective optimization problem. The sound attenuation for each considered frequency is determined by a hybrid method, which requires solving Helmholtz equation numerically by finite element method. The optimization is performed using non-dominated sorting genetic algorithm, NSGA-II, which is a multi-objective genetic algorithm. The hybrid numerical method is flexible with respect …

Multiobjective muffler shape optimization with hybrid acoustics modelling

2011

This paper considers the combined use of a hybrid numerical method for the modeling of acoustic mufflers and a genetic algorithm for multiobjective optimization. The hybrid numerical method provides accurate modeling of sound propagation in uniform waveguides with non-uniform obstructions. It is based on coupling a wave based modal solution in the uniform sections of the waveguide to a finite element solution in the non-uniform component. Finite element method provides flexible modeling of complicated geometries, varying material parameters, and boundary conditions, while the wave based solution leads to accurate treatment of non-reflecting boundaries and straightforward computation of the …

Rīcības ar cilvēka audiem un orgāniem regulējums Latvijā

2019

Darba tēma ir „Rīcības ar cilvēka audiem un orgāniem regulējums Latvijā”. Šobrīd, kad pasaulē strauji attīstās tāda medicīnas nozare kā cilvēka audu un orgānu transplantācija, pieaug arī cilvēka ķermeņa nelikumīgas izmantošanas gadījumi. Lai arī audu un orgānu nelikumīgas izmantošanas prakse Latvijā ir reti sastopama, arī šiem gadījumiem jāparedz atbilstošs regulējums starptautiskajiem tiesību avotiem. Darba mērķis bija noskaidrot, par kādām nelikumīgām darbībām ar cilvēka audiem un orgāniem ir paredzēta kriminālatbildība Latvijā, kādi ir embriju (fetālo) audu izmantošanas tiesiskie aspekti, un salīdzināt Latvijas tiesisko regulējumu ar starptautisko un ārvalstu regulējumu. Transplantācijas…
