TL;DR: The authors analyzed the South Korean policy and citizen attitudes regarding Joseonjok, or ethnic Korean Chinese citizens moving to South Korea, and showed how Korea's hierarchical nationhood is shaped by economic and geopolitical goals, and described analogous cases in Asia and Europe.
Abstract: Though nationhood is typically understood to be an equalizing or horizontal concept, the phenomenon of ethnic return migration has shown that states as well as societies can draw hierarchical distinctions between persons of the same ancestry. We demonstrate two dimensions - legal and social - of this 'hierar- chical nationhood' by analysing the South Korean policy and citizen attitudes regarding Joseonjok, or ethnic Korean Chinese citizens moving to South Korea. On the legal dimension, the Korean state defines Joseonjok as foreigners, allowing them entry mainly for low-wage jobs and excluding them from social benefits, while preferring them over other foreigners. The legal dimension of hierarchy is also institutionalized in a more favourable visa for Korean Americans that excludes Joseonjok. The social dimension of hierarchical nationhood is shown by public opinion data of Korean citizens towards Joseonjok foreign workers and data on reported experiences of discrimination. Finally, the authors show how Korea's hierarchical nationhood is shaped by economic and geopolitical goals, and describe analogous cases in Asia and Europe.

TL;DR: The synthesized AgNPs showed a moderate antibacterial activity against bacterial food pathogens and the nanocrystalline phase of Ag and Au with FCC crystal structures have been confirmed by X-ray diffraction analysis.
Abstract: In the present study, we synthesized silver and gold nanoparticles with a particle size of 10–20 nm, using Zingiber officinale root extract as a reducing and capping agent. Chloroauric acid (HAuCl4) and silver nitrate (AgNO3) were mixed with Z. officinale root extract for the production of silver (AgNPs) and gold nanoparticles (AuNPs). The surface plasmon absorbance spectra of AgNPs and AuNPs were observed at 436–531 nm, respectively. Optimum nanoparticle production was achieved at pH 8 and 9, 1 mM metal ion, a reaction temperature 50 °C and reaction time of 150–180 min for AgNPs and AuNPs, respectively. An energy-dispersive X-ray spectroscopy (SEM–EDS) study provides proof for the purity of AgNPs and AuNPs. Transmission electron microscopy images show the diameter of well-dispersed AgNPs (10–20 nm) and AuNPs (5–20 nm). The nanocrystalline phase of Ag and Au with FCC crystal structures have been confirmed by X-ray diffraction analysis. Fourier transform infrared spectroscopy analysis shows the respective peaks for the potential biomolecules in the ginger rhizome extract, which are responsible for the reduction in metal ions and synthesized AgNPs and AuNPs. In addition, the synthesized AgNPs showed a moderate antibacterial activity against bacterial food pathogens.

TL;DR: Temperature of 35°C and pH 7 were found to be optimum for maximum degradation and the mixed bacterial consortium showed more growth and degradation than did individual strains.
Abstract: A preliminary study was undertaken to determine the optimal conditions for the biodegradation of a crude oil. Among 57 oil-degrading bacterial cultures isolated from oil-contaminated soil samples, Bacillus sp. IOS1-7, Corynebacterium sp. BPS2-6, Pseudomonas sp. HPS2-5, and Pseudomonas sp. BPS1-8 were selected for the study based on the efficiency of crude oil utilization. Along with the selected individual strains, a mixed bacterial consortium prepared using the above strains was also used for degradation studies. The mixed bacterial consortium showed more growth and degradation than did individual strains. At 1% crude oil concentration, the mixed bacterial consortium degraded a maximum of 77% of the crude oil. This was followed by 69% by Pseudomonas sp. BPS1-8, 64% by Bacillus sp. IOS1-7, 45% by Pseudomonas sp. HPS2-5, and 41% by Corynebacterium sp. BPS2-6. The percentage of degradation by the mixed bacterial consortium decreased from 77 to 45% as the concentration of crude oil was increased from 1 to 12%. Temperature of 35°C and pH 7 were found to be optimum for maximum degradation.
