Morphological variability within the indigenous sheep population of Benin
19 octobre 2021, HE CondorcetArticle scientifiqueKnowledge of both the genetic diversity and geographical distribution of animal genetic resources is a prerequisite for their sustainable utilization, improvement and conservation. The present study was undertaken to explore the current morphological variability within the sheep population in Benin as a prelude for their molecular characterization. From November 2018 to February 2020, 25 quantitative ... -
A new manufacturing chain for ceramic shaping: sequential combination of milling and laser machining in green ceramic
juin 2020, DEMARBAIX, Anthonin
; Ducobu, François; Petit, François; Rivière-Lorphèvre, Edouard, HE Condorcet
Acte de conférence ou de colloqueContribution to euspen’s 20th International Conference & Exhibition (Geneva, CH, June 2020) Abstract : "The ceramic microcomponents have very interesting mechanical and thermal properties in an extreme environment such as a high temperature, a corrosive environment, etc. Unfortunately, the principal limitation of ceramic material usage is its shaping because of the brittlness of the material. ... -
A new phenotype of Polymyxa betae in Arabidopsis thaliana
21 avril 2011, HE CondorcetArticle scientifique"The aim of this work was to assess the infection of P. betae in Arabidopsis thaliana in order to learn more about the P. betae genome and its interaction with the host." Extrait de l'abstract -
Not in your usual Top 10 : protists that infect plants and algae
11 juillet 2017, HE CondorcetArticle scientifiqueFungi, nematodes and oomycetes belong to the most prominent eukaryotic plant pathogenic organisms. Unicellular organisms from other eukaryotic lineages, commonly addressed as protists, also infect plants. This review provides an introduction to plant pathogenic protists, including algae infecting oomycetes, and their current state of research. -
Numerical Modelling of the Heat Source and the Thermal Response of an Additively Manufactured Composite during an Active Thermographic Inspection
19 décembre 2023, Notebaert, Arnaud; Quinten, Julien; Moonens, Marc; Oldez, Vedi; Barros, Camila; Cunha, Sebastião Simões Jr.; DEMARBAIX, Anthonin, HE Condorcet
Article scientifiqueAbstract : "This paper deals with the numerical modelling of non-destructive testing of composite parts using active thermography. This method has emerged as a new approach for performing non-destructive testing (NDT) on continuous carbon fibre reinforced thermoplastic polymer (CCFRTP) components, particularly in view of detecting porosity or delamination. In this context, our numerical model has ... -
Oilseed Rape Cultivars Show Diversity of Root Morphologies with the Potential for Better Capture of Nitrogen
14 décembre 2021, HE CondorcetArticle scientifiqueThe worldwide demand for vegetable oils is rising. Oilseed rape (Brassica napus) diversifies cereal dominated crop rotations but requires important nitrogen input. Yet, the root organ is offering an untapped opportunity to improve the nitrogen capture in soil. This study evaluates three culture systems in controlled environment, to observe root morphology and to identify root attributes for superior ... -
Pedigree Validation and Reconstruction Applied in the Cultivated Potato Using 35 Microsatellites Markers
05 juin 2023, HE CondorcetCARAHArticle scientifiqueAbstract ; "Knowledge of the parental origin of crop species is a prerequisite for formulating efective strategies for genetic conservation, management, and utilisation of genotypes in breeding programmes and genetic studies. In the case of the potato, although pedigree information is well documented, the possible lack of accurate pedigree data for certain cultivars constitutes a loss of opportunity ... -
Plant Microbiota Beyond Farming Practices: A Review
29 mars 2021, HE CondorcetArticle scientifique"Being able to engineer microbial communities in ways that benefit crop health and growth will help decrease the number of chemical inputs required. Against this background, this review explores the impacts of agricultural practices on soil- and plant-associated microbiomes, focusing on plant growth-promoting microorganisms from a metagenomic perspective." Extrait de l'abstract -
Prediction of local sintering in laser beam machining of green Y-TZP ceramic
20 mai 2020, Ducobu, François; Rivière-Lorphèvre, Edouard; DEMARBAIX, Anthonin; Lauwers, Berth, HE Condorcet
Article scientifiqueAbstract : "Laser beam machining of Y-TZP engineering ceramic material is carried out in green stage to increase the material removal rate. The generation of hot spots may cause local sintering of the ceramic material leading to a decrease of the mechanical properties of the final sintered component. This paper presents the implementation of alternative laser beam paths to reduce the hot spots ... -
Que nous apprend cette 1ère mesure de l’activité biologique des sols ?
22 juin 2023, HE CondorcetCARAHPublication d'intérêt général/presse"Évaluer la fertilité des sols n'est pas trivial. Très souvent, on résume cela à une série de mesures physico-chimiques telles que le pH, la granulométrie (texture), la richesse en éléments nutritifs (P, K, etc.) ou le statut organique (teneur en carbone total). Cette approche a ses avantages car elle se base sur des procédures éprouvées et bien souvent standardisées, relativement rapides et stables ... -
Systemic resistance induced by Bacillus lipopeptides in Beta vulgaris reduces infection by the rhizomania disease vector Polymyxa betae
19 décembre 2012, HE CondorcetArticle scientifiqueThe control of rhizomania, one of the most important diseases of sugar beet caused by the Beet necrotic yellow vein virus, remains limited to varietal resistance. In this study, we investigated the putative action of Bacillus amylolequifaciens lipopeptides in achieving rhizomania biocontrol through the control of the virus vector Polymyxa betae. Some lipopeptides that are produced by bacteria, ... -
Use of self-organizing map to analyze images of fungi colonies grown from Triticum aestivum seeds disinfected by ozone treatment
16 octobre 2012, HE CondorcetCARAHArticle scientifiqueWe submitted to ozone treatment Triticum aestivum (common wheat) seeds severely contaminated by fungi. Fungi colonies developed when seeds were placed over malt agar medium in Petri dishes; Fusarium sp. and Alternaria sp. were identified. However, conventional colonies counting did not allow a clear assessment of the effect of ozone disinfection. We thus used self-organizing maps (SOMs) to perform ... -
Valorization of dairy waste and by-products through microbial bioprocesses
28 novembre 2021, HE CondorcetArticle scientifiqueWaste is an inherent and unavoidable part of any process which can be attributed to various factors such as process inefficiencies, usability of resources and discarding of not so useful parts of the feedstock. Dairy is a burgeoning industry following the global population growth, resulting in generation of waste such as wastewater (from cleaning, processing, and maintenance), whey and sludge. These ... -
Valorization of sugar beet pulp to value-added products: A review
février 2022, HE CondorcetArticle scientifiqueThe processing of sugar beet in the sugar production industry releases huge amounts of sugar beet pulp as waste which can be considered a valuable by-product as a source of cellulose, hemicellulose, and pectin. Valorization of sugar beet pulp into value added products occurs through acid hydrolysis, hydrothermal techniques, and enzymatic hydrolysis. Biochemical conversion of beet pulp into simple ... -
