Influence of the modes of shaping of sand-resin shellis on quality of the produced castings

open access: yesЛитьë и металлургия, 2019
Resin in sand-resin mixes in the course of heating at production of casting shell molds undergoes changes of a state: solid – liquid – solid. For the purpose of increase in durability and decrease in contents of binding (pulverbakelit) in mix when ...

Energy consumption for ion transport in a segmented Paul trap [PDF]

open access: yes, 2018
There is recent interest in determining energy costs of shortcuts to adiabaticity (STA), but different definitions of "cost" have been used. We demonstrate the importance of taking into account the Control System (CS) for a fair assessment of energy ...

Study of Asphaltene Solutions by Electrical Conductivity Measurements Conductivité électrique des solutions d'asphaltènes

open access: yesOil & Gas Science and Technology, 2006
The asphaltene interactions in model solutions were studied using a technique based on the electrical conductivity measurement. Interactions with n-heptane, resins, surfactants, water, phenol and NaCI were investigated.

Adhesion between the Resin Shell and Composite Resin.

open access: yesThe Journal of Nihon University School of Dentistry, 1992
Adhesiveness between the resin shell and composite resin was examined. As the resin shell, SR-PE-ISOCETTE, made from thermosetting crown and bridge resin, was used. The shear bond strengths between the resin shell and photocurable composite resin bonded by various methods were measured after 1-day of immersion in water at 37 degrees C. Super-bond C & B

L’EPURATION TERTIAIRE DES EAUX USEES DE L’INDUSTRIE DE LA CELLULOSE [PDF]

open access: yesAnnals: Series on engineering sciences (Academy of Romanian Scientists), 2010
Les processus de fabrication de la cellulose représentent des sources importantes de pollution tant pour les eaux, que pour l’aire et le sol. La pollution de l’eau est du, essentiellement, aux substances organiques dissous, aux substances en suspension ...

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

open access: yesFEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Résines et asphaltènes : évolution en fonction des types de matière organique et de leur enfouissement Resins and Asphaltenes: Evolution As a Function of Organic-Matter Type and Burial

open access: yesOil & Gas Science and Technology, 2006
151 résines et 175 asphaltènes d'extraits de roche de plusieurs bassins ont été étudiés par analyse élémentaire. On montre que : - les résines ont des valeurs moyennes en carbone et en hydrogène plus élevées ainsi qu'un rapport C/H plus faible que celui ...

Resin composite repair: Quantitative microleakage evaluation of resin-resin and resin-tooth interfaces with different surface treatments

open access: yesEuropean Journal of Dentistry, 2015
ABSTRACT Objective: The aim was to evaluate the effect of different adhesive systems and surface treatments on the integrity of resin-resin and resin-tooth interfaces after partial removal of preexisting resin composites using quantitative image analysis for microleakage testing protocol. Materials and Methods: A total of 80 human molar teeth

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Les cires de surbouchage : un élément esthétique ou fonctionnel ?

open access: yesIVES Technical Reviews
Une étude approfondie a été menée pour évaluer le transfert d'oxygène à travers différentes cires et résines, seules, ou utilisées en combinaison avec des bouchons à base de liège. Les travaux ont permis de répondre à une question cruciale que se posent
