To explore the physiological role of tetraheme cytochrome c(3) in the sulfate-reducing bacterium Desulfovibrio desulfuricans G20, the gene encoding the preapoprotein was cloned, sequenced, and mutated by plasmid insertion. The physical analysis of the DNA from the strain carrying the integrated plasmid showed that the insertion was successful. The growth rate of the mutant on lactate with sulfa...

A key element of the G20 response to the global financial crisis has been to develop policies to address the ‘too-big-to-fail’ problem posed by systemically important financial institutions (SiFis). the first step is to identify such entities. to that end, there has been extensive work undertaken in recent years, especially at the global level in view of the cross-country impact of large intern...

The paper investigates the contributions of foreign direct investment (FDI) net inflows to clean energy use, carbon emissions, and economic growth. The paper employs cointegration tests to examine a longrun equilibrium relationship among the variables and fixed effects models to examine the magnitude of FDI contributions to the other variables. The paper analyzes panel data of 19 nations of the...

We employ the difference-in-difference and synthetic control methods to investigate capitalization effect of hosting G20 Summit on land market, based China’s transaction dataset from 2011 2019. find that has a significant positive prices in host city, increasing by over 22.6% compared comparable cities. The impact is larger post-G20 period than preparation period. Further, heterogeneous distrib...

What kind of leadership role is China playing in the G20? How has this evolved over time, particularly with recent global crises created by COVID-19 pandemic? In addition, will China’s rising providing badly needed public goods reinforce its rivalry a declining US, present opportunity co-leading BRICS counterparts, or mediate and foster co-operative solutions among all? This study seeks to addr...

Signature-tagged mutants of Desulfovibrio desulfuricans G20 were screened, and 97 genes crucial for sediment fitness were identified. These genes belong to functional categories including signal transduction, binding and transport, insertion elements, and others. Mutants with mutations in genes encoding proteins involved in amino acid biosynthesis, hydrogenase activity, and DNA repair were furt...

Abstract Transparency in global value chains of materials, fuels, and food is critical for the implementation sustainability policies. Such policies should be led by G20, who represent more than 80% material, fuel, consumption. Multi-regional input–output analysis plays an important role consumption-based assessment, including supply their environmental impacts. However, previous accounting sch...
