Entanglement fidelity for electron-electron interaction in strongly coupled semiclassical plasma and under external fields

This paper presents the effects of AB-flux field and electric field on electron-electron interaction, encircled by a strongly coupled semiclassical plasma. We found that weak external fields are required to perpetuate a low-energy elastic electron-electron interaction in a strongly coupled semiclassical plasma. The entanglement fidelity in the interaction process has been examined. We have used partial wave analysis to derive the entanglement fidelity. We found that for a weak electric field, the fidelity ratio for electron-electron interaction increase as projectile energy increase but remains constant or almost zero for a strong electric field. Our results provide an invaluable information on how the efficiency of entanglement fidelity for a low-energy elastic electron-electron interaction in a strongly coupled semiclassical plasma can be influenced by the presence of external fields

Evolution of physical and mechanical characteristics of deposited composite coatings on A356 mild steel

This research investigated the development of Zn-SnO2/Zn-Al2SiO5 thin film on A356 mild steel using the electrodeposition technique. The developed coating was attained in 2.0 V for 10 min at a constant current density of 1.5 A/cm2. The electroplating process was maintained at a constant stirring rate of 250 rpm, temperature of 45 °C, 10 g of SnO2 was used for the bath while Al2SiO5 was varied from 5 to 15 g. The surfaces of coated samples were characterized using a scanning electron microscope (SEM). The effects of 3.56% NaCl on the coated and uncoated sample were examined via the potentiodynamic polarization technique, employing Autolab PGSTAT 101 Metrohm potentiostat with NOVA software of version 2.1.2. The outcome of the experiment revealed that the electrodeposited Zn-SnO2/Zn-Al2SiO5 exhibits better stability, improved microhardness, excellent microstructural qualities, and outstanding corrosion resistance. The Zn-10SnO2-15Al2SiO5-coated steel exhibits the lowest corrosion rate of 0.0473 mm/year, representing 99.32% reduction in corrosion rate compared to the uncoated sample. Similarly, a corrosion current density (jcorr) value of 20.5 μA/cm2 was recorded for the uncoated sample which is much greater than the jcorr of the coated samples. This shows that the coating minimizes the exchange of current within the steel. The hardness value of the Zn-10SnO2-15Al2SiO5-coated steel was higher than other coated samples and 17.51% higher than the uncoated steel, and this indicates improvement in the mechanical property of the steel

All hands on deck: levels of dependence between the EU and other international organizations in peacebuilding

The EU seeks extensive partnership with other international organizations when it comes to security challenges. This is puzzling as the EU relies for its resources mostly on its member states. The relations between the EU and other international organizations have thoroughly been studied, yet scholars rarely question the actual rationale for partnership. We start from resource dependency theory which explains that almost all organizations are dependent on the resources of their partners. Yet we extend this theory by distinguishing between macro, meso and micro-level dependencies. To illustrate resource dependencies between the EU and other international organizations, we analyse EU’s peacebuilding policies in Kosovo, Mali and Armenia. By accounting for macro- and micro-level dependencies we provide a more holistic perspective than conventional meso-level explanations. Our contribution is therefore to expand the scope of the resource dependency theory and provide a framework to analyse dependencies between the EU and other international organizations

Comparative study of the efficacy of Duocoxin and Amprol in relation to their effects on the development of resistance against mixed Eimeria infections in young chicks

Comparative efficacy of Duocoxin ® and Amprol ® on mixed populations of Eimeria necatrix, E. tenella,E. maxima and E. brunetti in chicks and their effect on the development of resistance against the infections were studied. The two anticoccidial drugs fed to chicks in drinking water for 14 days consecutively, or once 4 days after inoculation, inhibited and reduced oocyst production in chicks that had double exposure. Duocoxin ® was more efficacious than Amprol ® . When the two anticoccidials were fed to chicks 3 days before inoculation, pre-patent period was delayed, but the chicks later discharged more oocysts than those medicated for 14 days or once. The 60 mg/litre or 240 mg/litre of water levels of the two drugs did not interfere with the development of resistance against coccidiosis in the infected and medicated chicks. Chicks infected and medicated with the two anticoccidial agents for 14 days gained more weight, had better feed conversion rates and superior fecal and lesion scores than those that were either infected or medicated once after infection or those medicated 3 days before infection or those that were infected but not medicated. The two anticoccidials were not toxic in the chicks. Mortality rate was 14.29%-19.05% in chicks that were medicated once after infection; and 23.81%-28.57% in those medicated before infection. There was no death among chicks that were infected and medicated for 14days and those not infected but medicated for the same period. Animal Production Research Avancees Vol. 3 (1) 2007: pp. 55-6
