Daarnaast beoogt het project om in een samenwerking van technologische en gamma-georiënteerde kennisinstellingen te leren hoe de ontwikkelde kennis kan worden ingezet in nieuwe internationale agrogrondstofketens en hoe daarbij partnerships met het bedrijfsleven kunnen bijdragen aan de financiering van die kennisontwikkeling

    The relationship between amyloid structure and cytotoxicity

    Get PDF
    Self-assembly of proteins and peptides into amyloid structures has been the subject of intense and focused research due to their association with neurodegenerative, age-related human diseases and transmissible prion diseases in humans and mammals. Of the disease associated amyloid assemblies, a diverse array of species, ranging from small oligomeric assembly intermediates to fibrillar structures, have been shown to have toxic potential. Equally, a range of species formed by the same disease associated amyloid sequences have been found to be relatively benign under comparable monomer equivalent concentrations and conditions. In recent years, an increasing number of functional amyloid systems have also been found. These developments show that not all amyloid structures are generically toxic to cells. Given these observations, it is important to understand why amyloid structures may encode such varied toxic potential despite sharing a common core molecular architecture. Here, we discuss possible links between different aspects of amyloidogenic structures and assembly mechanisms with their varied functional effects. We propose testable hypotheses for the relationship between amyloid structure and its toxic potential in the context of recent reports on amyloid sequence, structure, and toxicity relationships

    Performative Work: Bridging Performativity and Institutional Theory in the Responsible Investment Field

    Callon’s performativity thesis has illuminated how economic theories and calculative devices shape markets, but has been challenged for its neglect of the organizational, institutional and political context. Our seven-year qualitative study of a large financial data company found that the company’s initial attempt to change the responsible investment field through a performative approach failed because of the constraints posed by field practices and organizational norms on the design of the calculative device. However, the company was subsequently able to put in place another form of performativity by attending to the normative and regulative associations of the device. We theorize this route to performativity by proposing the concept of performative work, which designates the necessary institutional work to enable translation and the subsequent adoption of the device. We conclude by considering the implications of performative work for the performativity and the institutional work literatures

    Acquisition of an Agrobacterium Ri Plasmid and Pathogenicity by Other -Proteobacteria in Cucumber and Tomato Crops Affected by Root Mat

    Get PDF
    Root mat of cucumbers and tomatoes has previously been shown to be caused by Agrobacterium radiobacter strains harboring a root-inducing Ri plasmid (pRi). Nine other pRi-harboring -Proteobacteria have subsequently been isolated from root mat-infected crops. Fatty acid profiling and partial 16S rRNA sequence analysis identified three of these strains as being in the genus Ochrobactrum, five as being in the genus Rhizobium, and one as being in the genus Sinorhizobium. An in vitro pathogenicity test involving inoculation of cucumber cotyledons was developed. All pRi-harboring -Proteobacteria induced typical root mat symptoms from the cotyledons. Average transformation rates for rhizogenic Ochrobactrum (46%) and Rhizobium (44%) strains were lower than those observed for rhizogenic A. radiobacter strains (64%). However, individual strains from these three genera all had transformation rates comparable to those observed from cotyledons inoculatedwith a rhizogenic Sinorhizobium strain (75%)

    We call a right-continuous increasing process KxK_x a partial right inverse (PRI) of a given L\'{e}vy process XX if XKx=xX_{K_x}=x for at least all xx in some random interval [0,ζ)[0,\zeta) of positive length. In this paper, we give a necessary and sufficient condition for the existence of a PRI in terms of the L\'{e}vy triplet.Comment: Published in at http://dx.doi.org/10.1214/09-AOP515 the Annals of Probability (http://www.imstat.org/aop/) by the Institute of Mathematical Statistics (http://www.imstat.org

    In the Slovenian language syllabus, teachers are recommended to provide a greater share of group work during class. During types of learning such as cooperative learning in smaller groups or pairs, students actively develop communicative competence. The present article presents a survey that attempted to determine whether teachers from the first to the fifth grade execute cooperative learning in language classes. The purpose of the article is to raise teachers’ awareness and encourage them to design and execute cooperative learning more frequently. (DIPF/Orig.

    This paper presents the results from an experimental study of the thermal method applied for obtaining platinum-group metals (PGMs) by melting used autocatalysts in an 80 kVA plasma reactor, using suitable fluxes and a reducing agent. As the collector of noble metals, grey cast iron was used during the melting. The melt products were the alloy, inert vitrified slag, syngas and fly ash. In the alloy, when melting the catalyser based on cordierite. there was 99.27 % PGMs and 99.00 % in the case of Cr/Ni-strip catalysts. The loss of PGMs in the slag during the melting of cordierite catalysts was 0.34 % and for Cr/Ni catalysts, it was 0.26 %. A chemical analysis of the ash confirmed that in addition to the mechanically removed CaO, SiO2, MgO, Al2O3, it also contained condensed vapours of Fe+PGMs. During the melting of the cordierite catalyst, the ash contained 0.40 % of the refined metals, while 0.74 % was the figure for the Cr/Ni-strip catalyst. The synthesis gas from the process had a very low heating value (0.16 MJ m(-3) or 0.24 MJ m(-3)).V tem članku avtorji predstavljajo rezultate eksperimentalnih raziskav termičnega postopka pridobivanja kovin platinske skupine (PGM, angl.: Platinum Group Metals) s taljenjem izrabljenih avtomobilskih katalizatorjev v 80 kVA plazemskem reaktorju z uporabo primernih talil in redukcijskega sredstva. Kot zbiralnik plemenitih kovin je bila med taljenjem uporabljena siva litina. Produkti taljenja so zlitina, inertna steklasta žlindra, sintezni plin in pepel. V zlitini je bilo pri taljenju katalizatorja na osnovi kordierita koncentriranih 99,27 % PGM, pri katalizatorjih s Cr/Ni trakom pa 99,00%. Pri taljenju kordieritnih katalizatorjev se je v žlindri izgubilo 0,34 % PGM, pri Cr/Ni katalizatorjih pa 0,26 %. Kemijska analiza pepela je potrdila, da poleg mehansko pridobljenih oksidov CaO, SiO2, MgO, Al2O3, le-ta vsebuje tudi kondenzirane pare Fe in PGM. V pepelu se je pri taljenju katalizatorja na osnovi kordierita nahajalo 0,40 % plemenitih kovin, pri katalizatorju s Cr/Ni trakom pa 0,74 %. Sintezni plin iz procesa taljenja je imel zelo nizko kurilno (kalorično) vrednost (0,16 MJ m–3 oz. 0,24 MJ m–3).Web of Science52334033
