Green Ceramic Machining: Determination of the Recommended Feed Rate for Y-TZP Milling
01 septembre 2021, DEMARBAIX, Anthonin
; Mulliez, Marylou; Rivière-Lorphèvre, Edouard; Spitaels, Laurent; Duterte, Charles; Petit, Fabrice; Ducobu, François, HE Condorcet
Article scientifiqueAbstract : "Manufacturing of advanced ceramic parts exhibiting complex geometries is laborious and expensive. Traditionally, the machining is carried out on a so-called ‘green ceramic’: a compact composed of ceramic powder held with the help of a binder. This difficulty is due not only to the composition of the material, but also to the lack of methods that determine optimal machining parameters. ... -

Intraspecific size shifts in generalist bumblebees and flowers lead to low functional consequences
04 septembre 2023, HE CondorcetArticle scientifiqueAbstract : "Body size is a trait that can affect plant–pollinator interaction efficiency and plant reproductive success. We explored the impact of intraspecific size shifts on the interactions between pollinators and flowering plants under controlled conditions. We considered two development conditions leading to the production of large and small individual flowers of Borago officinalis and Echium ... -
Investigation and development of potato parentage analysis methods using multiplexed SSR fingerprinting
25 décembre 2014, HE CondorcetCARAHArticle scientifiqueParentage assessment in the potato (Solanum tuberosum L.), based on a reliable characterization of DNA varieties, can be a useful tool in validating pedigree information as well as for assigning potential parents to orphan varieties. The approach suggested in this study was to use the genetic profiles obtained on 577 cultivars using a set of 17 polymorphic simple sequence repeats (SSR) markers in ... -

Molecular interactions between sugar beet and Polymyxa betae during its life cycle
20 janvier 2014, HE CondorcetArticle scientifique"Polymyxa betae is a biotrophic obligate sugar beet parasite that belongs to plasmodiophorids. The infection of sugar beet roots by this parasite is asymptomatic, except when it transmits Beet necrotic yellow vein virus (BNYVV), the causal agent of rhizomania. To date, there has been little work on P. betae–sugar beet molecular interactions, mainly because of the obligate nature of the parasite and ... -
