Повний текст джерелаCage rearing systems of laying hens is disappearing in Europe, in favour of cage-free systems that offer living conditions more respectful of the animals’ welfare. Hens live in groups and have access to nests for the egg-laying. Usually, laying hens have been bred in breeding programmes based on a measurement of the egg-laying in cages. The development of electronic nests that continuously record egg-laying in the nests offers the opportunity to change breeding programmes by raising pure lines in groups and on the floor.The first objective of this thesis was to characterize the egg-laying in nests and to study the genetic determinism of potential selection criteria to improve it. The second objective was to estimate the effects of genotype-by-environment interactions between floor and cage systems, for egg quality and body weight.The third and last objective was to explore a reorganisation of breeding programmes assuming the end of the use of cages.The egg-laying in nests was studied through 14 new traits related to egg-laying, laying rhythm, nest preference, time spent in the nest, and social behaviour. Heritability estimates for these traits were moderate-to-high and genetic correlations were low with egg quality and body weight. Genotype-by environment interactions were found to be limited. These results confirm the opportunity of selecting hens on egg-laying without the use of cages

Повний текст джерелаThis work deals with the opto-electronic and magnetic properties of zinc oxides and fluorides. In a first part, NIR absorption / reflection properties of aluminium and gallium doped zinc oxides powders have been studied. Dopant rates have been accurately determined for different experimental conditions and correlated with optical properties which were measured by diffuse reflection spectrometry. The same investigation has been performed on zinc fluoride but this compound could not have been doped by aluminium because of high chemical stability of aluminium fluoride. However, a structural study has been carried out on zinc hydroxyfluoride, which can be doped by aluminium. The last part of this dissertation deals with the investigation of carriers effect, which can be followed by diffuse reflection, on magnetic properties of cobalt doped zinc oxide. Free carriers have beeb no effect, only a paramagnetic behaviour has been observed

Повний текст джерелаThis thesis presents the results of a statistical study of the geometrical features of grain boundaries in nickel oxide NiO obtained by thermal oxidation of nickel. This work is divided into two parts: The first is a critical study of the methods used to determine the geometrical characteristics of the grain boundaries, orientation relationships, coincidence index, criteria of specialty, grain boundary plane. In the second part, we present the date of the study of 128 boundaries taken in 3 types of specimen resulting either from oxidation or additionally annealed. The following features were examined for each sample: granular morphology, distribution and density of dislocations, distribution of grain boundaries between subgrain boundaries and boundaries, oxidation texture, orientation relationships, "special" grain boundaries. It is shown in particular that boundaries parallel to a {011} plane are quite unstable and that the proportion of coincident boundaries is higher than that existing in a randomly distributed sample

Повний текст джерелаThe electronic state distribution of the NiO antiferromagnetic ground state has been studied within the local spin density approximation. All electrons, including the localized 3D electrons, are described by means of itinerant states according to the translational symmetry. The wave functions and energies are obtained self-consistently through a spin polarized linear combination of atomic orbitals method. Unlike a classical calculation, the charge fluctuations have been taken into account and related to a potential acting specifically on the 3D electrons. The main term in that potential is the on-site electrostatic interaction U between two electrons. The presence of U alters the repartition of the allowed and forbidden electronic states as well as the degree of hybridyzation of the eigenfunctions. The results show that the occupied 3D bands are narrow and nearly separated. The calculated gap value is in agreement with the experimental value when U is adjusted to 5. 4 eV. The occupied and empty 3D functions are those predicted by the ligand field applied to an atom in a cubic surrounding. The oxygen 2p bands reside below the small dispersive metallic 3D bands and confer a Mott insulating character to NiO. Nevertheless the full bands are not entirely pure because U enhances the ratio of the oxygen 2p functions within these bands. The theoretical electronic state diagram allows the interpretation of the whole experimental results particulary the optical absorption and the photoemission. Finally the satisfactory agreement with the angular photoemission spectra shows the ability of our approch to describe the ground state of NiO
