Notch Signaling in Pigment Cells and Generation of Mouse Models for Ocular Diseases

Bhushan Sarode

Cellular signaling mediated by Notch receptors results in coordinated regulation of cell growth, survival and differentiation. In melanocytes, Notch signaling is essential for the maintenance of melanocytes and the melanocyte stem cell population. Whereas, ...

High-statistics study of K-S(0) pair production in two-photon collisions

Mingkui Wang, Olivier Schneider, Chao Wang, Yiming Li, Jun Yong Kim

We report a high-statistics measurement of the differential cross section of the process gamma gamma -> (KSKS0)-K-0 in the range 1.05 GeV

Application des réseaux de Bragg à la détermination des déformations distribuées dans les matériaux composites

The behaviour of brittle matrix fibre reinforced-composites is dependent of the properties of its constituents (fibre, matrix and fibre-matrix interface) and is affected by the mechanical and environmental loads. The fracture of a unidirectional composite ...

UV-cured Epoxy for Adhesion in Steel Reinforced Thermoplastic Composites

Basile Golaz

This work addresses the development of composite materials that contain metallic load-bearing cords with the aim of combining outstanding mechanical performance with added functionality, including electrical conductivity, data transmission, and temperature ...

Anthocyanins and betalains as light-harvesting pigments for dye-sensitized solar cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Jun Ho Yum

We present the photoelectrochemical properties of dye-sensitized solar cells using natural pigments containing betalains and anthocyanins as sensitizers. The dyes extracted from grape, mulberry, blackberry, red Sicilian orange, Sicilian prickly pear, eggpl ...

Photocatalytic Discoloration of Organic Compounds on Outdoor Building Cement Panels Modified by Photoactive Coatings

César Pulgarin, Victor Sarria

Cement based Eternit plates modified by TiO2/SiO2 surface layers acquired self-cleaning properties. The TiO2/SiO2 coating was transparent indicating that the small TiO2 (rutile) crystals cause no significant scattering. The parameters related to the compos ...

UV-curable epoxy primer for adhesion between metallic oxides and thermoplastic polyurethane

Jan-Anders Edvin Maansson, Véronique Michaud, Basile Golaz

We report results on the development of an innovative fast-curing coupling method using a UV-curable epoxy primer based on a cycloaliphatic di-epoxide resin. The materials to bond are metallic wires and a thermoplastic polyurethane matrix. The curing kinet ...

Epoxy-graphite Resistive Composites : Formulation, Characterization and Applications

Nathalie Sophie Adeline Serra

In this thesis, we proposed to study polymer-based thick-film resistors (TFRs) made of graphite particles dispersed in an epoxy matrix. Three main axes were investigated: formulation of the composites, characterization with the determination of electrical, ...

Model-Based deduction of CMYK Surface Coverages from Visible and Infrared Spectral Measurements of Halftone Prints

Roger Hersch, Thomas Bugnon

The Yule-Nielsen modified Spectral Neugebauer reflection prediction model enhanced with an ink spreading model provides high accuracy when predicting reflectance spectra from ink surface coverages. In the present contribution, we try to inverse the model, ...

Dynamic capillary effects in liquid composite moulding with non-crimp fabrics

Jan-Anders Edvin Maansson, Véronique Michaud

A technique is presented to measure the capillary pressure drop DPg during infiltration of non-crimp fabrics by a liquid matrix. Three types of liquids are used: polyethylene glycol (PEG) dissolved in water, a thermoset epoxy resin and a reactive thermopla ...
