The circular economy model in the socio-economic systems of the wood industry : the case of the Tomsk oblast
2021
Using the Circular Economy (CE) model appears to be today a means more and more employed by organizations and public policies to overcome the problem of waste and bring it to a new stage of progress: the one of sustainability. If the issue of diagnosis and the need for a transition to CE is generally no longer discussed, the question of its implementation is all the more so, especially in Russia. Depending on the type of economic sector and the territory considered, an CE strategy cannot be viewed in the same way. Whether in terms of natural resources, labour or capital, different economic factors are brought to interfere in the search for circularity and sustainability. The objective of th…

Combining work with family life is a topical and socially important question. This article examines how under-40-year old female PhD students with a family manage to combine the roles of a mother and a doctoral student in their everyday life and how they deal with the major and simultaneous challenges these roles bring. The focus is on the everyday challenges female PhD students face and the choices they have to make at the interface of family and study. This article is part of research examining the life course and future thinking of female PhD students. Nowadays the atmosphere of planning is all-pervasive. Individuals are expected to plan their life course carefully. They should plan thei…
<i>Datasharing</i>: guía práctica para compartir datos de investigación
2013
To associate research data to the published results favors their reuse by the scientific community, but this does not afford sufficient guarantees of preservation. To store them in databases solves this contingency and provides visibility, but in Spain there are not many services of this kind. For this reason, we describe, evaluate and discuss the pros and cons of foreign multidisciplinary data repositories that can be useful for researchers and information managers: Dryad, Figshare, Zenodo and Dataverse. It is still early to choose optimally and definitively one or the other application, so we conclude with recommendations to guide the user community and intermediaries.

Spectral approach to D-bar problems
2017
We present the first numerical approach to D-bar problems having spectral convergence for real analytic, rapidly decreasing potentials. The proposed method starts from a formulation of the problem in terms of an integral equation that is numerically solved with Fourier techniques. The singular integrand is regularized analytically. The resulting integral equation is approximated via a discrete system that is solved with Krylov methods. As an example, the D-bar problem for the Davey-Stewartson II equations is considered. The result is used to test direct numerical solutions of the PDE.© 2017 Wiley Periodicals, Inc.

Weeds sampling for map reconstruction: a Markov random field approach
2012
In the past 15 years, there has been a growing interest for the study of the spatial repartition of weeds in crops, mainly because this is a prerequisite to herbicides use reduction. There has been a large variety of statistical methods developped for this problem ([5], [7], [10]). However, one common point of all of these methods is that they are based on in situ collection of data about weeds spatial repartition. A crucial problem is then to choose where, in the eld, data should be collected. Since exhaustive sampling of a eld is too costly, a lot of attention has been paid to the development of spatial sampling methods ([12], [4], [6] [9]). Classical spatial stochastic model of weeds cou…
A multispecies approach for modeling the ecological impact of urban development using landscape graphs
2013
International audience; Managing urban sprawl is become a major concern in the field of landscape ecology, since the land use changes involved by urban development may affect the ability of wildlife species to move across the landscape. In order to compare the ecological impact of several urban patterns, we aim at combining two complementary approaches: 1) Simulations of residential development from an initial land use map, using morphological rules of urban development (i.e. fractal vs non fractal) and accessibility constraints; 2) Models of ecological networks applied to a given natural habitat, using a landscape graphs-based approach. As landscape graphs are built according to the moving…
