Francisco Pizarro de Rosa Arciniega-Un intento de legitimación de la voz de una historiadora
2022
A reading of the historical novel Francisco Pizarro, written by the Peruvian Rosa Arciniega in 1936, is proposed. Through the analysis of the work, we will reflect on the relationship of the writer with the national historiography and with the ideal of a woman who dominated Latin American political and cultural discourse in the first half of the 20th century. From this, we seek to identify the place that the author constructs for herself within the intellectual field.
Analysis of the angular acceptance of surface plasmon Bragg mirrors
2007
International audience; We analyze an important aspect of the behavior of surface plasmon polariton (SPP) Bragg mirrors: the dependence of the angular acceptance for reflection on the incidence angle. By means of leakage radiation microscopy, both in direct and Fourier space, we observe that the angular acceptance diminishes for increasing incidence angles. This effect, which can considerably affect the design of devices based on these elements, is shown to be the consequence of the decrease of the bandgap width with increasing incidence angle.

Seasonal dynamics of the bacterial community in forest soils under different quantities of leaf litter
2010
International audience; Soil microbial communities play an important role in soil carbon functioning, particularly in forest ecosystems. Their variation in response to climate change may affect soil carbon processes, highlighting the importance of understanding how environmental factors affect microbial communities. This study aimed to determine to what extent an increase in the quantity of fresh litter may affect heterotrophic mineralization of organic carbon and bacterial community structure in soil and litter. A litter manipulation experiment was performed in situ in a temperate deciduous forest. Three treatments of fresh litter inputs were considered: litter exclusion, natural condition…
Soil aggregates and humus systems
2016
The European Society for Soil Conservation Conference, organized by the Babes-Bolyai University will take place from 15th June to the 18th June 2016 at the Babes-Bolyai University of Cluj-Napoca in Cluj-Napoca, Romania. The conference will cover areas like Soils – Our Common Future” stresses the vital interconnection between soil and life, as well as its importance for the future of the human society.; International audience; The survey of few main morphological soil aggregates (with intrinsic biological, chemical and physical contents) reveals the existence of different humus systems. Recognizable by naked eyes in the field, each humus system is confined in an ecological frame (climate, ve…
Synchronie entre l'offre et la demande dans le cycle des nutriments: apprendre des écosystèmes naturels pour construire des agrosystèmes durables
2023
Redesigning agrosystems with more ecological regulations can help feed a growing population, preserve soils for future productivity and reduce environmental impacts. However, guidelines for redesigning agrosystems from natural systems are limited. Reviewing the last knowledge of ecosystem functioning, we outlined four ecological systems synchronizing the supply of soluble nutrients by soil biota to fluctuating plant nutrient demand. This synchrony limits deficiencies and excesses of soluble nutrient, which usually penalize both production and regulating services of agrosystems such as nutrient retention and soil carbon storage. We detail how ecological systems promoting synchrony can be ins…

L’umanismo nell’opera narrativa e divulgativa di Alberto Manzi
2019
Alberto Manzi is a key figure in the panorama of the development of Italian language and culture. The analysis of his biography and his writing highlights the humanism that characterizes all his literary works and his pedagogical thinking. A fil rouge that underlies his life and professional experiences, an urgency of renewal that results in a concrete commitment against injustice and ignorance, in the expression of a new paideia, in politically engaged writing.He wrote many novels (Grogh storia di un castoro, Collodi award, translated in 20 languages; Orzowei, honored at the Andersen award translated in 32 languages), tales, articles, informative writings; he developed TV and radio program…
