Economic sanctions against Russia: italian point of view
This article is devoted to the impact of economic sanctions against Russia imposed by the European Union on the economy of Italy and reflects the views of the Italians. Special attention is paid to the losses incurred by the economy of Italy
Kinetic Solvers with Adaptive Mesh in Phase Space
An Adaptive Mesh in Phase Space (AMPS) methodology has been developed for
solving multi-dimensional kinetic equations by the discrete velocity method. A
Cartesian mesh for both configuration (r) and velocity (v) spaces is produced
using a tree of trees data structure. The mesh in r-space is automatically
generated around embedded boundaries and dynamically adapted to local solution
properties. The mesh in v-space is created on-the-fly for each cell in r-space.
Mappings between neighboring v-space trees implemented for the advection
operator in configuration space. We have developed new algorithms for solving
the full Boltzmann and linear Boltzmann equations with AMPS. Several recent
innovations were used to calculate the discrete Boltzmann collision integral
with dynamically adaptive mesh in velocity space: importance sampling,
multi-point projection method, and the variance reduction method. We have
developed an efficient algorithm for calculating the linear Boltzmann collision
integral for elastic and inelastic collisions in a Lorentz gas. New AMPS
technique has been demonstrated for simulations of hypersonic rarefied gas
flows, ion and electron kinetics in weakly ionized plasma, radiation and light
particle transport through thin films, and electron streaming in
semiconductors. We have shown that AMPS allows minimizing the number of cells
in phase space to reduce computational cost and memory usage for solving
challenging kinetic problems
Recent developments in the political landscape of Spain and the European Landscape Convention
En este artículo se analiza el desarrollo de las políticas paisajísticas en España, especialmente en su etapa actual, cuando el
paisaje se ha convertido en un instrumento importante para la diagnosis y el desarrollo del territorio. En primer lugar, se
estudian las diferentes etapas en la evolución de las políticas del paisaje en España, desde el periodo donde el paisaje sólo
tenía un significado artístico y cultural (principios del siglo XX) hasta la firma y ratificación por España del Convenio Europeo del
Paisaje (CEP) que establece un marco común para las políticas paisajísticas europeas. Se realiza un análisis crítico de los
planteamientos del CEP y de los problemas de su implementación en España. Se hace hincapié en la problemática de la
democracia y participación pública en la toma de decisiones políticas en materia de ordenación del territorio y paisaje que
recomienda el CEP y las dificultades para llevar a cabo las medidas que allí se proponen. Como conclusión, se realiza una
reflexión sobre la integración del paisaje en las políticas de ordenación del territorio europeas como una manifestación de la
emergencia de las formas más democráticas de gestión del territorio y sobre los nuevos retos de las investigaciones
paisajísticas.In this article the development of the landscaping policies in Spain is analyzed, especially in its present stage, when the
landscape has become an important instrument for the diagnosis and the development of the territory. First of all, the
different stages of Spain’s landscape policies evolution are studied, from the period where the landscape only had an artistic
and cultural meaning (principles of century XX) up to the signature and ratification by Spain of the European Agreement of the
Landscape (CEP) that establishes a common frame for the European landscaping policies. Ratification for Spain of the European
Agreement of the Landscape (CEP) that establishes a common frame for the landscape European policies
A critical analysis of the expositions of the CEP and the problems of their implementation is realised. From the CEP some
Spanish regional laws were derived that they are examined next.
Like conclusion, a reflection is realised on the integration of the landscape in the policies of arrangement of the territory
European as a manifestation of the emergency of the most democratic forms of management of the territory and on the new
challenges of the landscaping investigationsFil: Frolova, Marina.

A Question of Mastery. Defects and Layers
This work began with a topic that was interesting and exciting to me: the technology of
multiple firing in ceramics and defective glazes. Almost immediately, I thought I knew how to
build a testing and scientific research process. My goal was to collect an extensive library of
effects and techniques that would meet my expectations, and using this palette, as a painter
move directly to the very process of creating art objects.
For the study, I chose one defect of my interest - the appearance of craters in the
glaze driven by Silicon Carbide (SiC) and the dependence of the characters of the craters on
the amount of SiC. The project was undertaken to evaluate how crater glazes work with
other glazes such as copper red and crystalline glazes in layers, which will provide a variety
of glazing textures.
In the process of working with defects in glazes, there was an encounter with control,
a desire to conform to the outlined plan, followed by the attempt to free myself and follow a
more organic process. "Two" fundamental questions emerged on which to base the study of
my art practice:
1. What are the layers of process that make up my artistic practice? Who are the
participants in this process: the inner values, intuition, the material with which I
interact, fire, chance...something else?
2. What role do 'chance and control’ play in my art practice?
Trying to find answers to these questions brought me closer to personal understanding about
my artistic practice:
● Dealing with uncertainty
● Failure and disappointment
● Empathy for the material
● Trust of fire
● Acting, not just planningEste trabalho começou com um tópico que era interessante e entusiasmante para mim: a
tecnologia de múltiplas cozeduras em cerâmica e vidrados com “defeitos”. Quase
imediatamente, consegui imaginar um protocolo para testar estes processos de forma
científica. O meu objetivo foi recolher uma extensa biblioteca de efeitos e técnicas que
fossem ao encontro das minhas expectativas, usando esta paleta diretamente no processo
de criação de obras de arte.
Para o estudo, escolhi um dos defeitos que me interessavam – o aparecimento de crateras
(ou pústulas) no vidrado por efeito do carboneto de silício (SiC) e a relação entre as
características das crateras e quantidade de SiC. O estudo incluiu ainda a avaliação da
interação entre os vidrados de crateras (crater glaze) e outros – tais como o vidrado
vermelho de cobre e os vidrados cristalinos – quando aplicados em camadas, originando
uma variedade de texturas e cores.
No processo de trabalhar com os defeitos em vidrados, deparei-me com a questão do
controlo, com o desejo de corresponder a um plano delineado, a que se seguiu a tentativa
de me libertar e seguir um processo mais orgânico. Surgiram “duas” questões fundamentais
nas quais basear o estudo da minha prática artística:
1. Quais são as camadas do processo que constituem a minha prática artística? Quem são
os participantes neste processo: os valores intrínsecos, a intuição, o material com que
interajo, o fogo, o acaso... algo diferente?
2. Que papel desempenham o “acaso e o controlo” na minha prática artística?
Tentar responder as estas questões aproximou-me de uma compreensão pessoal acerca da
minha arte:
· Lidar com a incerteza
· Fracasso e desilusão
· Empatia pelo material
· Confiar no fogo
· Agir, não planear apenas
