ماتلاب فييمIndex. décimale : 622 Electro-Technique Résumé :
This thesis aims to: study, design and comparison of innovative generators adapted to the conversion of renewable energies, especially wind power in a direct drive. From a power (1.5 MW) and speed (1.55 rad / s) data given, we are dimensioned analytically two innovative topologies of machines to associate with a wind turbine with high power without gearbox.
The first topology is a Permanent Magnets Synchronous Machine with Low Speed (PMSMLS) and the second topology is an innovative generator for wind turbine that is the Switched Reluctance Machine with Low Speed (SRMLS), therefore, with large diameters. Start by an analytical model, we calculated the main dimensions of PMSMLS and the SRMLS and simulated operation of the generators from a numerical approach based on the finite element method.
Eventually, we performed a comparatives analysis of design equations, volumes, weights and costs of two different topologies of wind turbines generators studied (PMSMLS and the SRMLS).
Our work was mainly focused on the permanent magnet generator because this machine seems to be the most cost effective and most widely used in recent years. However, thanks to developments made in different areas and with the high cost of the magnets, the switched reluctance generator interests more researchers and industry for wind generators applications.Diplôme : Doctorat En ligne : ../theses/electrotec/LEB6905.pdf Format de la ressource électronique : Permalink : index.php?lvl=notice_display&id=10237 Performances comparées de machines synchrones à aimants permanents et à réluctance variable associées à une chaine de conversion d'energie renouvelable [texte imprimé] / Abdelkadir Lebsir, Auteur ; Ammar Bentounsi, Directeur de thèse ; Mohamed Benbouzid, Directeur de thèse . - جامعة الإخوة منتوري قسنطينة, 2016 . - 109 f. ; 30 cm.

Japanese quail is a very interesting bird. Thus, this research was undertaken to determine feed formulas specific to it (at the different production stages) by partially substituting soy with locally produced cheaper protein-crops.
Each formula contains either of the entire Faba beans, treated Faba beans or peas for forage at several substitution levels: 10, 20 or 30% of the ration.
The results showed that quails of batches that received treated Faba beans have recorded the best performances (growth and laying) in comparison with those of the other groups. The entire Faba beans had adverse impacts especially on growth in relation with anti-nutrients. The peas for forage had close effects of 44% soybean meal, but its high fiber and average protein contents represent a limitation to its incorporation at high levels.
The substitution of soybean meal with treated Faba beans led to a hypoglycemia and a reduction of uremia with hypercalcemia and hyperphosphatemia. The entire Faba bean conducted to the same results of hypoglycemia and decrease of uremia which were accompanied by hyperproteinemia. The peas for forage have no effect on the biochemical parameters of Coturnix japonica except a non-significant decrease of uremia.
Finally, the treated Faba bean and peas for forage could solve the import problem of soybean meal in our country, but this requires more extensive studies with higher levels of incorporation and accurate analysis of bigger number of parameters (performances, nutritional, organoleptic, biochemical, hematological and histological).

Two groups of 200 broilers, strain ISA15, have been raised in the same building with the same ambient conditions, lighting, and feeding, during two periods, the first, in spring time (April- May). ) and the second in the autumn period (October-November).broilers received three vitamin treatments in the drinking water (chicktonic premix, vitE / selenium and antistress, betamint)from 1day to 48 day. In order to avoid cases of rickets or growth retardation, as well as breeding stress , all chickens in the summer treated with chicktonic as miltivitamin and betamint. The lots were identified according to the following therapeutic schema: control lot CH (chicktonic 1ml /, betamint 1ml / then 2ml / l from day 41). Lot CH + 41 (chicktonic 1ml / l then 2.5 ml / l from day 41, betamint, same as controllot ). Lot CH + 13 (chicktonic 1ml / l, then increasing the dose gradually from day 13). Lot VitE / Se + 41 (1ml / l then 2.5 ml / l from day 41, betamint, same as controllot ). Lot VitE / Se + 13 (1ml / l, then increase the dose gradually from day 13). Lot Bet + 13: chicktonic 1ml / l, betamint 1ml / l, then increase the dose gradually from day 13). The results obtained are significant at the p< 0.05, for live weight, yields, and blood profile. We obtained the best live weight (2821.33 g ± 229.77) with the increase in the dose of vitamin E / Selenium from day 41. Increased doses of chicktonic from day 41 improved performance, IC (2.08 ± 1.0) and IP (358.24 ± 313.25) and CV% (8.3), as well as serum cholesterol (1.23 g / l ± 0.17) and blood glucose (2.34 g / l ± 0.21), but carcass yield (74.70% ± 4.99) and that of organs are better when the doses were increased from day 13. Increasing the selvite dose from day 13 gave a lower IC (1.6 ± 1.6). The organ yield is better with the lowest abdominal fat yield (0.69 ± 0.28). The increase in dose of antistressBetamint, gave a high level of total protein (34.50 g / l ± 4.63), that of cholesterol (1.32 g / l ± 0.17) and that white blood cells (952.2610 ^ 3 / μl ± 26.60). With respect to the mortality rate, the three treatments gave low values between 0.10% and 0.33%.Diplôme : Doctorat en sciences En ligne : ../theses/veterinaire/CHO7467.pdf Format de la ressource électronique : Permalink : index.php?lvl=notice_display&id=11298 Influence de l’apporten vitamines et antistress sur les performances zootechniques et le profil hématologique chez le poulet de chair.
