Opis:
Brucellosis is a worldwide zoonosis, that can still be classified as endemic despite its ancient origins which causes economic losses and public health problems. Although effectively controlled by vaccination in animals, there is currently no vaccine for use in humans. Outer Membrane Proteins (OMP) that play an active immunogenic and protective role in the Brucellae family. OMP19 is present in all Brucella species as a surface antigen and is a potent immunogen responsible for Brucellosis intracellular infection. For this reason, the study was aimed to be used safely as a potential recombinant vaccine candidate against all Brucella infections, especially in humans and pregnant animals. This study evaluated a Brucella lipoprotein antigen, i.e. 19 kilodalton (kDa) outer membrane protein (OMP19), which was amplified and cloned into the pETSUMO vector system. The immunogenic power of the purified recombinant OMP19 antigen against brucellosis was compared with that of OMP19 (Raybiotech Inc, USA) in a mouse model and the obtained rOMP19 antigen was found to be similar to the commercially available recombinant protein.

Opis:
The influence of severe plastic deformation on wear properties of Al-5wt.%Grp and Al-5wt.%B₄Cp reinforced aluminum matrix composites was studied. Al matrix composites were produced by solid state processing via powder metallurgy route that provides good incorporation and distribution of the reinforcement particles in the matrix. Wear tests were performed by dry sliding using a pin on disk wear tester. Scanning electron microscope was used to examine worn surfaces to study the wear mechanism. Severely deformed specimens exhibited better wear resistance due to the increase of surface hardness of both Al-5wt.%Grp and Al-5wt.%B₄Cp composites. Al-B₄Cp reinforced composite has higher hardness value through the excellent hardness of B₄C particulates. Al-Grp reinforced composites exhibited better wear resistance due to the solid lubricant effect of Gr particulates.

Opis:
Treating chalcopyrite flotation concentrates by hydrometallurgical techniques seems to be the most convenient method for leaching copper due to concerns over air pollution and regulations regarding the emission of sulfur dioxide that result from smelting. In this study, the leaching recovery-time trajectories of bulk chalcopyrite concentrate obtained from a flotation plant in the Kastamonu region of Turkey are presented. The effects of various parameters were elucidated in the nitrous-sulfuric acid electrolyte (CNaNO2:0.05 M–0.15 M, CH2SO4:1 M) at a moderate temperature (80–120 °C). A high level of copper recovery (98%) from bulk chalcopyrite concentrate was obtained under a total pressure of 6 atm at 120°C within 2 h when using small amounts of nitrite species due to their autocatalytic behavior in acidic solutions. The kinetics were well correlated with the shrinking core model for the diffusion controlled mechanism with an apparent activation energy of 34.06 kJ·mol–1. Elemental sulfur was the primary leaching product on the mineral surface, as confirmed using XRD and SEM/EDX. The semi-empirical equation explaining the reaction rate under the present conditions was expressed as follows: ...[wzór].
