Towards events ontology based on data sensors network for viticulture domain
2018
International audience; Wine Cloud project is the first "Big Data" platform on the french viticulture value chain. The aim of this platform is to provide a complete traceability of the life cycle of the wine, from the wine-grower to the consumer. In particular, Wine Cloud may qualify as an agricultural decision platform that will be used for vine life cycle management in order to predict the occurrence of major risks (vine diseases, grape vine pests, physiological risks, fermentation stoppage, oxidation of vine, etc...). Also to make wine production more rational by offering winegrower a set of recommendation regarding their strategy's of production development. The proposed platform "Wine …
Porous 3D Printed Scavenger Filters for Selective Recovery of Precious Metals from Electronic Waste
2018
Selective laser sintering (SLS) 3D printing is used to fabricate highly macroporous ion scavenger filters for recovery of Pd and Pt from electronic waste. The scavengers are printed by using a mixture of polypropylene with 10 wt% of type‐1 anion exchange resin. Porosities and the flow‐through properties of the filters are controlled by adjusting the SLS printing parameters. The cylinder‐shaped filters are used in selective recovery of Pd and Pt from acidic leachate of electronic waste simply by passing the solution through the object. Under such conditions, the scavenger filters are able to capture Pd and Pt as anionic complexes with high efficiency from a solution containing mixture of dif…
The effect of sad mood on early sensory event-related potentials to task-irrelevant faces
2023
It has been shown that the perceiver's mood affects the perception of emotional faces, but it is not known how mood affects preattentive brain responses to emotional facial expressions. To examine the question, we experimentally induced sad and neutral mood in healthy adults before presenting them with task-irrelevant pictures of faces while an electroencephalography was recorded. Sad, happy, and neutral faces were presented to the participants in an ignore oddball condition. Differential responses (emotional – neutral) for the P1, N170, and P2 amplitudes were extracted and compared between neutral and sad mood conditions. Emotional facial expressions modulated all the components, and an in…
Polyoxypregnanes as safe, potent, and specific ABCB1-inhibitory pro-drugs to overcome multidrug resistance in cancer chemotherapy in vitro and in vivo
2021
Multidrug resistance (MDR) mediated by ATP binding cassette subfamily B member 1 (ABCB1) is significantly hindering effective cancer chemotherapy. However, currently, no ABCB1-inhibitory drugs have been approved to treat MDR cancer clinically, mainly due to the inhibitor specificity, toxicity, and drug interactions. Here, we reported that three polyoxypregnanes (POPs) as the most abundant constituents of Marsdenia tenacissima (M. tenacissima) were novel ABCB1-modulatory pro-drugs, which underwent intestinal microbiota-mediated biotransformation in vivo to generate active metabolites. The metabolites at non-toxic concentrations restored chemosensitivity in ABCB1-overexpressing cancer cells v…
Positive effects of an extracellular matrix hydrogel on rat anterior cruciate ligament fibroblast proliferation and collagen mRNA expression
2015
Summary Background/Objective We have previously shown that an extracellular matrix (ECM) bioscaffold derived from porcine small intestine submucosa (SIS) enhanced the healing of a gap injury of the medial collateral ligament as well as the central third defect of the patellar tendon. With the addition of a hydrogel form of SIS, we found that a transected goat anterior cruciate ligament (ACL) could also be healed. The result begs the research question of whether SIS hydrogel has positive effects on ACL fibroblasts (ACLFs) and thus facilitates ACL healing. Methods In the study, ECM-SIS hydrogel was fabricated from the digestion of decellularised and sterilised sheets of SIS derived from αGal-…
Liiketoimintatiedon hallinnan soveltuvuus urheiluorganisaation käyttöön : case AKK Sports Oy
2016
Nykyisessä tietoyhteiskunnassa johtamisen roolin tulisi perustua aiempaa enemmän liiketoimintatietoon, joka on systemaattisempaa ja ennakoivampaa kuin ennen. Tietotarpeiden määrittäminen ja tunnistaminen toimii lähtökohta- na tiedolla johtamisen prosesseissa ja tehokkaan liiketoimintatiedon hallinnan hyödyntämisessä. Liiketoimintatiedon hallinta on toimintaa, jonka avulla orga- nisaatio kerää, analysoi, jakaa ja hyödyntää oman toimintansa kannalta merkit- tävää liiketoimintatietoa. Kypsyysmallien tarkoitus on tuottaa organisaatiosta analyyttinen arviointi, joka toimii tukipilarina organisaation kehittymisproses- sissa. Kypsyysmalleja käytetään kuvaamaan, selittämään ja arvioimaan organi- sa…
Seinäjoen Aalto-keskuksen paikan henkeä etsimässä : "Alvarin askelissa" -teemalukuvuoden suunnitteluprosessin kuvaus
2015
Tutkimukseni kuvaa suunnitteluprosessia, jonka tuloksena syntyi luonnostelma ”Alvarin askelissa” teemalukuvuonna (2015–2016) käytettävistä arkkitehtuurikasvatuksen menetelmistä. Teemalukuvuosi johdattaa Seinäjoen kaupungin perusopetuksen 2., 5., 7. ja 8. luokkien oppilaita havainnoimaan ja tiedostamaan arkkitehtuurin ja rakennetun ympäristön merkitystä heidän omassa ympäristössään. Teemalukuvuoden keskiössä on Seinäjoen Alvar Aallon suunnittelema, kuusi rakennusta ja kansalaistorin käsittävä, arkkitehtoninen kokonaisuus, jota kutsutaan Aalto-keskukseksi. Tavoitteena on, että oppilaat oppivat tiedostamaan, että heidän kotikaupungissaan on maailmanlaajuisesti tunnetun arkkitehdin ainutlaatuin…
Crystal structure of sinhalite MgAlBO4 under high pressure
2015
We report on high-pressure angle-dispersive X-ray diffraction data up to 27 GPa for natural MgAlBO4 sinhalite mineral and ab initio total energy calculations. The experimental bulk modulus of sinhalite is B-0 = 171(3) GPa with a first-pressure derivative of B-0' = 4.2(3). A comparison with other olivine-type compounds shows that the value for B0 is 27% larger than that of Mg2SiO4 forsterite and 29% smaller than that of Al2BeO4 chrysoberyl. These differences are interpreted, on the basis of our ab initio calculations, in terms of the relative incompressibility of Al-O bonds in AlO6 octahedra (with a calculated bulk modulus of 250(1) GPa) as compared to Mg-O bonds in MgO6 octahedra (with a ca…
Apprentissage automatique de réseaux d'interaction à partir de données de séquences de nouvelle génération
2022
Climate change and other human-induced processes are modifying ecosystems, globally, at an ever increasing rate. Microbial communities play an important role in the functioning ecosystems, maintaining their diversity and services. These communities are shaped by the different abiotic environmental effects to which they are subjected and the biotic interactions between all community members. The ANR Next-Generation Biomonitoring (NGB) project proposed to reconstruct interaction networks from abundance measures obtained sequencing environmental DNA (eDNA) and to use these networks to monitor ecosystem change. In this thesis, conducted as part of the NGB project, I evaluate the potential of tw…
The role of parasitism in adaptive radiations – when might parasites promote and when might they constrain ecological speciation?
2012
Research on speciation and adaptive radiation has flourished during the past decades, yet factors underlying initiation of reproductive isolation often remain unknown. Parasites represent important selective agents and have received renewed attention in speciation research. We review the literature on parasite-mediated divergent selection in context of ecological speciation and present empirical evidence for three nonexclusive mechanisms by which parasites might facilitate speciation: reduced viability or fecundity of immigrants and hybrids, assortative mating as a pleiotropic by-product of host adaptation, and ecologically-based sexual selection. We emphasise the lack of research on specia…
