In this work, we took Dendranthema indicum as a target plant and two stored insects which include Tribolium castaneum and Stegobium paniceum adults as target insects. Essential oil obtained from Salair indicum was analyzed by gas chromatography-mass spectrometry GC-MS. A total of 31 components representing Significantly, in the progress of assay, it showed that the essential oil and chamazulene exhibited stronger insecticidal and repellent activities against Stegobium paniceum than Tribolium castaneum.
The results indicate that additional to its traditional use as Chinese medicinal herb, the essential oil of Dendranthema indicum aerial parts and isolated compounds have potential to be developed into natural insecticides or gdille for control of insects in stored grains. The present study examines the financial profitability grilld beekeeping in Cameroon.
The global objective is to compare the profitability of two types of bee farms in the North West Region. The osnatrach hypothesis, however, is the following: As regards the methodology used, a two stage stratified random sampling technique was used to select bee farmers. Primary data was collected on elements of costs and revenue.
The technique of cost benefit analysis was used to analyze the data. Findings showed that traditional beekeeping and semi-modern beekeeping using Kenyan hives “KTBH” farms have an average production of The semi-modern bee hives perform better than the traditional one.
Even with some difficulties faced by some farmers, bee farming in the North West Cameroon remains profitable. Despite the static character of this study, we suggest that beekeepers should adopt the semi-modern Kenyan hives.
Comparative study of energy conversion system dedicated to a small wind turbine; Etude comparative de chaines de conversion d’energie dediees a une eolienne de petite puissance. This study presents a comparison of architectures and strategies of energy management dedicated to VAWT turbines such as Savonius. A Maximum Power Point Tracking must be implemented in order to optimize the energetic behavior.
A torque or a speed control, or an indirect control of the DC bus current is possible. In the fact that the wind turbine characteristic is unknown, an operational research based on fuzzy logic is proposed. Aiming to minimize the cost of the static conversion structure, simple structures diode bridge inverter, associated with DC-DC chopper are analyzed and compared with a system based on a PWM Voltage Source Inverter.
A test bench has been realized in the meantime as a system simulation. Comparisons of the provided energy are made for different wind speeds allowing to evaluate the performance of each structure and of the control strategies. A comparative study of both the evolution of strontium content in the bones of individuals of different ages for the period as related to calcium, and the corresponding diets allowed to establish the relationship between food contribution and the resulting bone burden.
The study is mainly devoted to the group of adults for which a mathematical expression is proposed which allows for the exchangeable form of a skeletal calcium fraction turned over in less than a year from the dietary calcium, and the stabilized form constituting the larger part of bone tissue characterized by a slow turnover. Both the amount of the exchangeable fraction and the turnover rate of the stabilized fraction are determined for vertebrae and ribs.
At birth, bone levels indicate that the calcium used for skeleton modelling during foetal life originates from both maternal diet and bone tissue and a value is given, to their relative significance. There appears a good relationship between bone levels in infants from 6 months to 1 year of age and their diets. The physiological parameters particular to this age are quantified.
L’essentiel de l’ etude est consacre au cas des adultes. Pour ce groupe la formulation mathematique proposee tient compte de la presence de la forme echangeable d’une fraction du calcium osseux, renouvelee en moins d’un an a partir du calcium alimentaire, et de la forme stabilisee, constituant la majeure partie du tissu osseux, caracterisee par un renouvellement lent.
L’importance de la fraction echangeable, ainsi que le taux de renouvellement de la fraction stabilisee sont etablis pour les vertebres et les cotes. Comparative study of the creep behaviour of single crystals and polycrystals of alpha uranium; Etude comparee du comportement au fluage de l’uranium alpha mono et polycristallin. In the first chapter, one describes the creep machine developed to study the deformation of uranium at high temperature in vacuum with a continuous recording.
The second chapter presents the results concerning the polycrystals of uranium. The study of the variation of the creep rate with the applied stress and the metallographic observations of the deformation induced polygonization allow to conclude that the deformation is controlled by climb of dislocations.
The major deformation mode is slip. The preexisting polygonization of these single crystals is very stable and the disorientation between adjacent sub-grains increases with the deformation.
The activation energy for creep is higher than that for polycrystals. Le deuxieme chapitre presente les resultats relatifs aux polycristaux. L’ etude de l’influence de la contrainte appliquee sur la vitesse de fluage et l’observation micrographique de la polygonisation developpee au cours de la deformation permettent de conclure que le phenomene est controle par la montee des dislocations.
Dans le troisieme chapitre, on etudie le comportement au fluage au-dessus de C des monocristaux obtenus par.

Cast duplex stainless steels are commonly used in components of pressurized water reactors primary circuit. When submitted to in-service temperatures embrittlement occurs because of the nucleation and growth of a harder phase in the ferrite by spinodal composition.
Macrostructure of this steel ferritic primary grain size is about mm and embrittlement of ferrite due to aging lead to a very high scattering of mechanical properties xalaire monotonous loadings. We showed that, in spite of this macrostructure, the cyclic behaviour of aged duplex stainless steels fits usual Manson-Coffin law while initial hardening is followed by softening, in part because of the demodulation of the composition.
The fatigue crack propagation rate of material follows a Paris law.
While crack initiation mainly appears next to the millimetric cast defects, fatigue crack propagation remains a continuous mechanism. Ferritic and austenitic elements break successively ferrite first breaks by cleavage, then austenite breaks by ductile fatigue. In spite of the salsire that the aged ferrite is embrittled, cleavage microcracks, for load levels examined, seldom appear in ferrite at the crack tip and on both sides of the main crack.
Effects of cast defects and crystallographic ferrite orientation were also studied. Propagation fatigue crack behaviour was modeled assuming that the crack tip material behaves as if it was submitted to low cycle fatigue loadings.
If we consider a homogeneous material, results are in good agreement with experiments.
