Contribution to "euspen’s 19th International Conference & Exhibition, Bilbao, ES, June 2019"
Abstract :
"The requirements for quality amelioration of engineered products are increasingly stringent, and specially when the miniaturization and difficult-to-machine materials are considered. The development of hybrid machining processes (HMPs) answers this problem.
Indeed, HMPs are variants of ...

Contribution to "Euspen’s 17th International Conference & Exhibition, Hannover, DE, May 2017".
Abstract : "The demand for micro products has increased gradually since last decades in various areas, requiring the development of micro manufacturing processes. Micro manufacturing is characterized by the size of functional features (smaller than 10 um), a high precision, a good surface finishing and ...

"The aims of this paper is to study the advantages and disadvantages of laser micro-machining and the micro-milling. The final goal is to couple these processes in the same structure. The sequential hybrid process is subtractive-subtractive it combines the laser u-machining and the u-milling. The samples are machined with the two processes to compare the dimensional tolerance and the geometrical ...
Behaviour of pre-sintered Y-TZP during machining operations: Determination of recommended cutting parameters

- Article scientifique
Article scientifique
"In this paper,the NF E 66-520-5 standard, dedicated to the determination ofthe optimal cutting parameters suitable for ductile material, is applied to the pre-sintered ceramic Y-TZP. The objective of the standard is to calculate the specific cutting energy of the forces created between the chosen tool and material during machining operation. Specific cutting energy is the energy required to remove ...
Chemical etching as a finishing process for electron beam melting (EBM) parts

Acte de conférence ou de colloque
"The goal of this research is to analyze the impact of chemical etching on parts produced by electron beam melting. Given that the surface conditions are poor (Ra between 25 to 35 µm), an enhancement of these is asked. Dimensional and surface measurements were realized on conceived parts. Different exposure times were tested. The impact of these times on surface quality was evaluated. To help ...
In Vitro Dual Culture of Polymyxa betae in Agrobacterium rhizogenes Transformed Sugar Beet Hairy Roots in Liquid Media

- Article scientifique
Article scientifique
"Polymyxa betae is a soil-borne protist and an obligate parasite of sugar beet that transmits the beet necrotic yellow vein virus. Sugar beet hairy roots, transformed by Agrobacterium rhizogenes, were inoculated with surface-sterilized root fragments infected by P. betae. After 10 wk in a liquid medium, typical structures of P. betae were observed in this in vitro system. This first in vitro culture ...
Molecular interactions between sugar beet and Polymyxa betae during its life cycle

- Article scientifique
Article 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 ...

- Article scientifique
Article scientifique
The 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, ...
Not in your usual Top 10 : protists that infect plants and algae

Article scientifique
Fungi, 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.
