yersiniosis is a common infection in human and animals. yersinia enterocolitica infection has been associated with a variety of clinical manifestations. this bacterium has been isolated from water, meat, milk environment, animals and so on. our studies have been accomplished about isolation of y. enterocolitica from vegetables such as lettuce, carrot, celery, parsley, tomato, cabbage, radish, m...

a new approach for analyzing cracked problems in 2d orthotropic materials using the well-known element free galerkin method and orthotropic enrichment functions is proposed. the element free galerkin method is a meshfree method which enables discontinuous problems to be modeled efficiently. in this study, element free galerkin is extrinsically enriched by the recently developed crack-tip orthot...

  Performance and capacity of sulfur recovery unit (SRU) are greatly affected by the H2S:CO2 ratio of the acid gas stream. The acid gases in Iran contain around 35 mol% H2S and 60 mol% CO2. This low concentration of H2S calls for more complex sulfur plant, larger equipments, and higher costs. Acid gas enrichment processes (AGE) is run to upgrade low quality acid gas collected from gas treating...

The paper announces that the Ministry of Energy and Environmental Protection Ukraine has developed “Ukrainian Green Deal”, ambitious goal which is transition to a climate-neutral economy, reducing greenhouse gas emissions decarbonizing economy by 2070. “European Deal” provides for achievement similar goals 2050. It mentioned share biomethane “green” methane in overall system transmission consum...

In this study, batch experiments were carried out to investigate the effectiveness of persulfate (PS) as an oxidant agent remediate benzene, toluene, ethylbenzene, and xylenes (BTEX) in saline environments at high water temperatures (30 °C). This hydrological setting is quite common contaminated groundwater aquifers Middle Eastern countries. general, increasing system temperature from 10 30 °C ...

Large Eddy Simulation (LES) with Conjugate Heat Transfer (CHT) is used to analyze the impact of H2-enrichment on flame structure and combustion dynamics a lean partially-premixed turbulent CH4/Air swirling flame. Experimentally, combustor operated at atmospheric pressure H2 fuel fractions up 50%, by volume. LES-CHT results are compared validated against time-resolved stereo PIV, OH* chemilumine...
