Vr̥kṣa vivāha. Dendrogamie in India fra tradizioni antiche e pratiche devozionali contemporanee
2021
An inextricable tangle of branches and roots arises in many Indian villages in the place where two trees united in marriage (vr̥kṣa vivāha), grow intertwining with each other in an everlasting 'embrace'. This interweaving describes well the complex network of symbols and textual references that are revealed in the relationships that Indian culture has built around a pair of trees: the aśvattha and the śamī. In this paper, I will try to highlight some mythological and ritual aspects related to this pair. The two trees, in fact, although in today's context separately, are the object of rituals that turn out to be true tree marriages. In particular, concerning aśvattha, what is striking is tha…
Un Churel Mandir in Gujarat. Note sulla diffusione delle rappresentazioni della figura della strega in India
2021
The churels are figures of the folk imagery of a vast area of South Asia. They, commonly identified with witches, are spirits of women who died during pregnancy or childbirth, and who return to the world of the living, possessing them. The aim of this study is to provide an interpretative analysis of the representations of the churels and of the ambiguous climate that has been created around these figures in recent decades in India. A reflection on the power of the representations of the churels throughout history up to present-day India could be considered a key to penetrating the dense network of relationships and reinventions, but also of divergences and contradictions, sometimes with tr…
In the footsteps of the cows The ritual of gavāmayana between ancient and contemporary India
2022
Codified in classical Vedic times (8th-4th century BCE), the gavāmayana (‘the cow path’) was a year-long ritual session (sāmvatsarikasattra), which accompanied the succession of months of the Vedic religious calendar and ended with the celebration of mahāvrata (‘the great vow’) during the winter solstice. Marking the conclusion of the arduous ritual journey, it celebrated rebirth and consecrated the beginning of the new year. The book investigates gavāmayana based on a philological analysis of the texts and on a historical-religious and anthropological perspective, focusing on ancient India and some contemporary practices. The mahāvrata, in particular, seems to preserve the memory of very a…
Ragazze folli di miele, Il miele e la celebrazione della parola nel rito del mahāvrata
2021
In these pages, we will explore the rite of mahāvrata, a Vedic rite connected to the celebration of the new year, from a study perspective aimed at the performative dimension. Specifically, I will focus on the final scene of the rite, because it is only at this moment that the actors and the ritual dynamics compose a particular scenario, evocative of fertility, in which some maidens, the ritual fire, and honey are the protagonists. The maidens are called upon to dance around the mārjālīya hearth and to intone a chant in which they repeat the word madhu ("honey") in an increasingly frenzied manner. The words spoken, in some cases meaningless formulas, reveal a unitary sense and hint at the f…
Etude de l'influence de l'hydratation des laitiers sur les propriétés de transfert gazeux dans les matériaux cimentaires
2015
Cements with high slag content are currently studied as possible candidate for nuclear waste containment materials. In this context it is important to know their microstructure and the transport properties (permeability and diffusion) of the gases that are formed by the radiolysis of the water present in this material. According to literature, these properties are strongly impacted by the addition of blast furnace slag. The aim of this work is to correlate the hydration processes of slag blended cements with their transport properties. In the first part of this work, the hydration of the slag blended cements, for which only few results have been reported to date, has been studied. Silicon-2…
Analyse cartographique de données pédologiques et hydrogéologiques appliquée à la gestion responsable de produits phytosanitaires
2014
BASF launched a Responsible Bentazone Management plan in 2011, in order to preserve water resources and sustain its bentazon based herbicide solutions. This molecule is commercialized by the company for several years and is found at concentrations above the standard for drinking water in about 1% of groundwater catchments in France. The action plan aims to reduce contamination situations with recommendations on the use of bentazone (dose, timing of application, restrictions on vulnerable soils on groundwater catchment areas) that complement the commercialization authorization. The study carried out during the internship focused on the diagnosis of a groundwater catchment area located in the…
Rôle des espèces sulfures dans la corrosion des aciers non alliés : hétérogénéités de la couche de produits de corrosion et couplages galvaniques
2014
The present study relates to the problem of the long-term interim storage of nuclear wastes. In France, it is envisaged that high-level radioactive wastes will be confined in a glass matrix, stored in a stainless steel canister, itself placed in a carbon steel overpack. The wastes will then be stored at a depth of ~450 m in a deep geological disposal, drilled in a very stiff (indurated) clay (argillite) formation. A temperature as high as 90°C is expected at the steel surface because of the intense radioactivity. Anodic polarization at applied current density was used to synthetize corrosion product layers likely to be formed in storage conditions. The S235 steel electrodes were covered by …
FINDUS: An Open-Source 3D Printable Liquid-Handling Workstation for Laboratory Automation in Life Sciences
2020
3D-printed laboratory devices can enable ambitious research purposes even at a low-budget level. To follow this trend, here we describe the construction, calibration, and usage of the FINDUS (Fully Integrable Noncommercial Dispensing Utility System). We report the successful 3D printing and assembly of a liquid-handling workstation for less than $400. Using this setup, we achieve reliable and flexible liquid-dispensing automation with relative pipetting errors of less than 0.3%. We show our system is well suited for several showcase applications from both the biology and chemistry fields. In support of the open-source spirit, we make all 3D models, assembly instructions, and source code ava…
UV resistance of Bacillus subtilis spores - Involvement of DPA and characterization by photonic microscopy
2022
The aim of this project was to study the UVc resistance of Bacillus subtilis spores. The first part of this project focused on the dipicolinic acid molecule (DPA) which is known to be involved in the UV resistance of spores. However, some points remain unresolved. In particular, it is known that this molecule forms fluorescent photoproducts (DPAp), which were not identified at the beginning of this project. No information concerning the role of these DPAp in UVC resistance was available at that time. During this project, a protocol was established to follow the appearance of these photoproducts directly inside the spore core. A method was also set up to artificially introduce DPAp into the …
"Diagonale des Fous" : stratégie événementielle d'un ultra-trail
2016
Une recherche pédagogique, appliquée au cas du Grand-Raid, qui traite de la stratégie événementielle d'une organisation sportive au travers des jeux d'acteurs, d'une logique touristique et dans un environnement concurrentiel en développement. Le Grand-Raid/Diagonale des fous est un Ultra-trail, organisé par l'association du Grand-Raid, sur l'île de La Réunion. A l'heure où les sports de randonnée, de nature et de découverte se développent, l'étude de la stratégie événementielle d'une telle manifestation prend toute son importance.
