The prevalence of lipids devoid of phosphorus suggests that the availability of phosphorus limits microbial growth and activity in many anoxic, stratified environments. To better understand the response of anaerobic bacteria to phosphate limitation and starvation, this study combines microscopic and lipid analyses with the measurements of fitness of pooled barcoded transposon mutants of the mod...

In order to characterize the genetic diversity and phylogenetic affiliations of marine cyanophage isolates and natural cyanophage assemblages, oligonucleotide primers CPS1 and CPS8 were designed to specifically amplify ca. 592-bp fragments of the gene for viral capsid assembly protein g20. Phylogenetic analysis of isolated cyanophages revealed that the marine cyanophages were highly diverse yet...

Purpose The Group of 20 (G20) is tasked with responding to economic shocks in the global financial system, COVID-19 having proved be most significant shock since G20's inception. also represents first crisis accompanied by a concerted attempt “build back better”, principally through climate-compatible recovery. In 2021, there little clarity as response this challenge, primarily due considerable...

Parallel zur Wirtschaftsund Finanzkrise war nach 2008 bei vielen Beobachtern der Eindruck entstanden und medial dann kräftig vermittelt worden, als habe die G20 (= Gruppe der 20 wichtigsten Industrieund Schwellenländer – vgl. www.g20.org) nicht nur die G7 bzw. G8 (USA, Jap., D, F, GB, I, Can + Russ. seit 1998) als ordnungspolitisches Kraftzentrum abgelöst, sondern auch effektiv die Neuordnung d...

The design and implementation team of computer automation systems for the Polish power industry faced many difficult problems connected with the lack of experience in this domain in the country. Another kind of problems was implied by different levels of information and communication technology in that country and in well developed ones. The differences were generated by both internal (importat...

The influential papers on the effect of credit constraints on growth and international trade (Rajan and Zingales, 1998; Manova, 2013) tend to assume that asset tangibility and the share of external borrowing are exogenous industry characteristics, which are timeand country-invariant. In the finance literature, however, the share of external borrowing is viewed as endogenous and dependent on the...

The purpose of this paper was to compare the relative efficiency COVID-19 transmission mitigation among 23 selected countries, including 19 countries in G20, two heavily infected (Iran and Spain), highly populous (Pakistan Nigeria). for each country evaluated at stage by using data envelopment analysis (DEA) tools changes were analyzed across stages. Pearson correlation tests conducted between ...
