Corn grain (Zea mays L.) is widely produced all over the world and is intensively used in poultry and pigs feeding. Drying with hot air is usually utilized to preserve corn after harvest by decreasing the water content. During high temperature drying, major components (starch and proteins) of corn grain undergo some structural changes with possible nutritional implication. This thesis aimed at increasing knowledge regarding the effect of the drying process on the feeding value of the corn grain for broilers and pigs feeding. After the general introduction and a review which attempts to summarize the major findings of previous studies carried out on the effects of drying on the nutritive value of corn for broilers feeding, the first in vitro experiment performed aimed to assess the effect of fluidized-bed drying on the digestibility of dry matter, starch and protein using a sequential pepsin-pancreatin protocol. It appeared that when corn grains harvested at similar moisture content are dried at different temperatures, the digestibility of starch and that of crude proteins are not affected in a similar way. Higher drying temperatures increased the final digestibility of starch while the digestibility of crude proteins decreased mainly during the pepsin step of digestion. Differences in the kinetics of starch digestion according to the corn grain temperature were attributed to the structural modifications induced within starch granules and proteins in response to the drying conditions. As the digestion of starch involves the breakdown of glycosidic bonds and results in the production of various oligosaccharides, a second experiment was performed in order to get more insight into the nature of saccharides released after the in vitro digestion of corn grains. Three methods were thus compared in their ability to provide relevant information about sugar saccharides released during an in vitro digestion procedure that mimics the pig digestive model. High Performance Anion Exchange Chromatography coupled with a Pulsed Amperometric Detector was revealed to give the most effective qualitative and quantitative information regarding the digestion of starch. Five major saccharides were found as the result of in vitro pepsin-pancreatin digestion of corn grain: glucose, isomaltose, maltose, maltotriose and glucosyl-maltotriose. The relative concentration of these saccharides varied according to the temperature applied during the corn drying, suggesting that structural changes occurring within starch granules (partial gelatinization) would lead to different digestion profiles in the small intestine and may therefore affect the nutritional physiology in pig intestinal tract. Protein is also affected by the high drying temperature. Among corn protein subgroups, salt-soluble proteins are the most sensitive to heat and their solubility decreases when the drying temperature increases. In a third experiment, the denaturation of salt-soluble proteins during corn drying and hydrothermal treatment was monitored and modelled. The impairment of corn protein solubility in saline buffer was revealed to depend mainly on temperature, time of processing and moisture content of materials treated. The evolution of extractible salt-soluble proteins content of corn kernels during drying at high temperature was more correctly described using the second order kinetic reaction than with the first order kinetic reaction when classical kinetic models were compared. In a forth study the relationship between the in vitro digestibility of dry matter and the salt-soluble protein index was assessed. It was found that the use of salt-soluble protein index as an indicator of the may lead to doubtful conclusion due to confounding factors (temperature and moisture content). Although this study has achieved some progress in understanding the possible link between corn drying parameters and their effects on the performance of poultry and pigs feeding using corn-based diets, as well as on methodologies that may be used to assess the nutritive value of dried corn grains, complementary studies aiming to determine the effectiveness of these effects on livestock and pigs have to be done.

« Ombres de réalité » a pour objectif de partager avec vous nombre d’erreurs personnelles – factuelles et d’appréciation –, à la lumière de ce que d’autres ont eu l’élégance de nous transmettre. Le socle de la réalité, lieu de convergence de ses ombres, et que décrit à merveille la comédie humaine, ne peut jamais être approché qu’au travers d’une recherche sincère et permanente. Apprendre à désapprendre résolument, apprendre à reconstruire patiemment, et apprendre à transmettre modestement, constituent le but ultime de la vie. Personnellement, je n’en vois pas d’autre aujourd’hui. Après une brève introduction, ou « Sortie de l’ombre », de courts chapitres couvrent un thème particulier, généralement à la lumière d’observations, d’expériences personnelles, ou de lectures qui m’ont touché. La sélection et l’ordre des sujets ne traduit aucun souci particulier, même si je ne crois plus beaucoup au hasard. Tous deux pourraient évoluer au fil des révisions que connaîtra ce texte dans les années à venir. Le choix actuel va de « Chacun pour soi » au « Secret du silence », en passant par « L’aventure à deux », « La foire aux illusions », « La tyrannie des marchés », « L’intérêt général », « Non ! merci », et « Une chance d’être ». Chaque thème peut être exploré isolément. A vous, donc, de constituer votre menu en fonction de votre curiosité et de votre appétit. [less ▲]

Calcium carbonate particles are promising candidates as proteins carriers for their controlled delivery in the body. The present paper aims at investigating the protein encapsulation by in situ precipitation of calcium carbonate particles prepared by a process based on supercritical CO2 and using a new type of degradable well-defined double hydrophilic block copolymers composed of poly(ethylene oxide) and polyphosphoester blocks acting as templating agent for the calcium carbonate. For this study, lysozyme was chosen as a model for therapeutic protein for its availability and ease of detection. It was found that by this green process, loading into the CaCO3 microparticles with a diameter about 2 mm can be obtained as determined by scanning electron microscopy. A protein loading up to 6.5% active lysozyme was measured by a specific bioassay (Micrococcus lysodeikticus). By encapsulating fluorescent-labelled lysozyme (lysozyme-FITC), the confocal microscopy images confirmed its encapsulation and suggested a core–shell distribution of lysozyme into CaCO3, leading to a release profile reaching a steady state at 59% of release after 90 min.

Any imbalance between electric power supply and demand results in power system frequency deviations from its nominal value. Frequency regulation is one of the most important services that regional system operators perform to ensure reliable system operation. Traditional power supply sources such as generators are usually automatically modulated to help balance generation and demand by adjusting their output based in part on system frequency. As a result of the decreased inertia of the system caused by decommissioning of traditional power plants and the increase in the penetration of renewable energy sources, the increased use of demand side controls for the purpose of frequency regulation is receiving increased attention. Demand control can provide fast response to any imbalance. This opens up the possibility for Electric Vehicles (EVs) to be used as frequency regulation grid resources. This write-up discusses the potential, opportunities and benefit of doing so. [less ▲]

Surface mass balance (SMB) variations of the Greenland ice sheet (GrIS) has been identified as an important contributor to contemporary and projected global mean sea level variations but their impact on the regional sea level change pattern is still poorly known. This study provides for the first time, consistent estimates (i.e. computed with the same models over the past -1900-2015- and over the future -2015-2100-) of GrIS SMB over 1900-2100 based on the output of 32 atmospheric-ocean General Circulation Models and Earth system models involved in the Climate Model Intercomparison Project phase 5 (CMIP5). It is based on a downscaling technique calibrated against the MAR regional climate model in order to calculate an ensemble of 32 Greenland SMB estimates at regional scale. Because the GrIS SMB does not respond uniformly to greenhouse gases (GHG) emissions. the southern part of the GrIS is more sensitive to climate warming. This study shows that it should be in imbalance in the 21st century sooner that the northern part. This regional variability affects significantly the associated relative sea level pattern over the entire ocean and particularly along the eastern coast of US and the northern coast of Europe. This highlights the necessity of taking into account GrIS regional SMB changes to evaluate accurately relative sea level changes in future projections. [less ▲]
