Acquisition et reproduction d'images couleur : approches colorimétrique et multispectrale

The goal of the work reported in this dissertation is to develop methods for the acquisition and reproduction of high quality digital colour images. To reach this goal it is necessary to understand and control the way in which the different devices involved in the entire colour imaging chain treat colours. Therefore we addressed the problem of colorimetric characterisation of scanners and print...

Physiology, Endocrinology, and Reproduction: Reproduction

conditions throughout the test. The hens were provided nutrients to meet the needs of all the hens based upon compilation of the breeder recommendations. The eggs from these strains were collected every 28 days from the previous 24 hrs production. Once collected the quality and compositional properties of the eggs such as pH, solids, whipping height, Haugh units and angel food cakes were evalua...

Le Chondriome De Trypanosoma Mega

Un organite d'ultrastructure typiquement mitochondriale a t6 rcemment observe chez les trypanosomes, en troite association avec le kin6tonucleus (3, 6-8, 17). Cette meme association a 6t6 trouvee chez un bodonide (14). Bien que de forme assez variable, cet organite est generalement allong6 et a souvent 6t6 decrit sous l'aspect d'un long tube ou canal (6, 7) sinueux, allant du kin6tonucleus chac...

Differents aspects du fer dans l'organisme

Des cellules réticulaires remplies de molécules de ferritine et d'hémosidérine se trouvent au centre "d'ilots érythroblastiques." Dans la zone de contact entre la cellule réticulaire chargée de ferritine et les érythroblastes, on voit des invaginations et des petites vacuoles au bord desquelles adhérent des molécules de ferritine. Il est postulé que la ferritine passe de la cellule réticulaire ...
