The dissolution behavior of nickel in the MgO-SiO 2-FeO slag system was investigated by using the thermodynamic equilibrium *** distribution ratio between molten MgO-SiO 2-FeO slag and molten Fe-Ni alloy at 1773 K and 1873 K was measured to understand the dissolution mechanism of nickel into the *** dependence of oxygen partial pressure and basicity on the distribution of nickel was *** distribution behavior between slag and Fe-Ni alloy increased with higher oxygen partial pressure showing a dependence of 1/*** basic slag systems near the olivine saturated composition,the nickel distribution ratio increased with higher basicity showing a slope of 1 and for acidic slag systems near the cristobalite saturated composition,the nickel distribution ratio decreased with higher basicity showing a slope *** dissolution behavior of nickel in the MgO-SiO 2-FeO slag system showed two independent mechanisms similar to that found in the CaO-SiO 2-CaF 2 *** distribution ratio of sulfur between the（CaO）-MgO-FeO-SiO 2 slag and Fe-Ni alloy at high temperature was also investigated to understand the refining ability of Ferronickel smelting slag by chemical equilibrating *** experimental results indicated that sulfide capacity in terms of the slag composition of MgO-FeO-SiO 2 slag and temperature was increased with increasing FeO and CaO contents as well as *** FeO is considered to work as relatively basic component in this slag system that has low *** the effect of components of slag on sulfide capacity,CaO and FeO is considered to be more effective basic oxide than MgO in MgO-FeO-SiO 2 slag system while the effect of FeO on sulfide capacity was gradually retarded with increasing *** effect of CaO on MgO solubility of slag and the relationship between sulfide and Ni oxide capacities was also discussed.

Global Genomic Variations of Pathogenic Bacteria <i>Salmonella</i>Reading

Computational Molecular Bioscience 2021年第3期11卷 57-68页

作者： Woo hyung Lee Yein Jeon Jonathan S. Chung Woo Jun Shim Min Jae Shin Seok Gyu Han Seunghan Baek James kim Jaewoo kim Paul S. Chung Biotechnology School of Sciences Hong Kong University of Science of Technology Hong Kong China Fuzbien Technology Institute Rockville USA Ernest Mario School of Pharmacy Rutgers University New Brunswick USA College of Letters & Sciences University of California Los Angeles USA Biology Bachelor of Science California Institute of Technology Pasadena USA School of Arts & Sciences Johns Hopkins University Baltimore USA School of Arts & Sciences University of Michigan Ann Arbor USA Youth with Talents Fairfax USA

US Centers for Disease Control and Prevention (CDC) estimates food-borne pathogenic Salmonella bacteria cause about 1.35 million infections, 26,500 hospitalizations, and 420 deaths in the U.S. every year. Outbreaks of multidrug-resistant Salmonella Reading linked mainly to raw turkey products and alfalfa sprouts have accounted for human illness including mortality. Therefore, we downloaded and compared genome sequences of 897 Salmonella Reading isolated from 27 resources in 11 countries at 21 year-points from the National Center for Biotechnology Information database. Isolates were clustered into 10 clades which consisted of 3 major and 7 minor or single node clades. Although 3 major clades included both Europe and American isolates, one clade consisted of 605 North American isolates out of 614 isolates. Evolutionary distance is more related to the continent than the source of isolation. The host source, continent (North America and Europe) and phylogenetic clade were related to the prevalence of isolates encoding Antimicrobial Resistance Genes (ARGs). Prevalence of prophages was greater in bovine and swine isolates than poultry and human isolates and the least prevalence was found in human isolates. Between continents, the prevalence of phage was greater in North Ame- rican isolates than European. The diversity of virulence factors in swine isolates differed from poultry isolate while no difference was found among continents. In conclusion, evolutionary distance is related to isolation host source rather than the continent, and genome features were distinguished by host and cluster. Our genomic analysis implies that Salmonella Reading evolved independently to environments within its lineages.

Development of a power control system for AUVs probing for underwater mineral resources

引用

Journal of Marine Science and Application 2009年第4期8卷 259-266页

作者： Young Jin kim hyung Tae kim Young June CHO Kang Won LEE Manufacturing System Division Korea Institute of Industrial Technology Technology Service Division Korea Institute of Industrial Technology

Valuable mineral resources are widely distributed throughout the seabed. autonomous underwater vehicles (AUVs) are preferable to remotely-operated vehicles (ROVs) when probing for such mineral resources as the extensive exploration area makes it difficult to maintain contact with operators. AUVs depend on batteries, so their power consumption should be reduced to extend exploration time. Power for conventional marine instrument systems is incorporated in their waterproof sealing. External intermittent control of this power source until termination of exploration is challenging due to limitations imposed by the underwater environment. Thus, the AUV must have a power control system that can improve performance and maximize use of battery capacity. The authors developed such a power control system with a three-step algorithm. It automatically detects underwater operational states and can limit power, effectively decreasing power consumption by about 15%.
