The Mycobacterium tuberculosis Rv2358-furB is induced by zinc
The Mycobacterium tuberculosis genome encodes two ferric uptake regulator homologues, furA and furB, the function of which is under investigation. Using Mycobacterium smegmatis as a model system, we investigated the transcriptional pattern of Rv(Ms)2358-furB genes. Transcripts covering the two genes could be identified by northern blotting and by reverse transcriptase PCR. The transcriptional start point was mapped at one base upstream of the Ms2358 start codon by the RACE technique. By cloning M. smegmatis and M. tuberculosis DNA regions upstream of a reporter gene, we demonstrated the presence of one promoter, located immediately upstream of the Rv(Ms)2358 gene. Promoter induction was tested on several cultures grown under different conditions of pH and temperature, and in the presence of different concentrations of metallic ions. The promoter was found to be specifically induced by zinc. The recombinant M. tuberculosis FurB protein typically contained two zinc ions per protein monomer. Complete removal of zinc could not be obtained, even with strong denaturation treatment. Our data are in favour of the hypothesis that Rv2358 and FurB are transcriptional regulators involved in zinc homeostasis

Adsorption of lead(II) and copper(II) on activated carbon by complexation with surface functional groups.
The adsorption of lead(II) and copper(II) on an activated carbon (Filtrasorb 300, Chemviron) was characterized assuming
that it takes place by formation of complexes with functional groups, present in the activated carbon. Their concentration and
conditional adsorption coefficients were determined for each metal by titration of the carbon in suspension in aqueous phase,
at constant acidity, with the metal itself. For each titration point, the concentration of the metal in the solution phase after
equilibration was determined, and the data were processed by the Ruzic linearization method, to obtain the concentration of
the active sites involved in the sorption, and the conditional constant. The effect of the pH was also examined, in the range
4–6, obtaining that the adsorption increases at increasing pH. The protonation and adsorption constants were determined from
the conditional adsorption coefficients obtained at the different acidities. The concentration of the active sites is 0.023 and
0.042 mmol/g, and the protonation constants are 1.0 × 10^(6) and 4.6 × 10^(4) M^(−1) for Pb(II) and Cu(II). The corresponding adsorption constants are respectively 1.4 × 10^(5) and 6.3 × 10^(3) M^(−1). All the parameters are affected by a large uncertainty, probably due to the heterogeneity of the active groups in the activated carbon. Even if so, these parameters make it possible a good prediction of the adsorption in a wide range of conditions. Other sorption mechanism can be set up at different conditions, in particular at different pH, as it has been demonstrated in the case of copper(II)

The Poem of Memory. "Triumphi"
Writing of the "Triumphi" Fabio Finotti finds that its author undercuts a medieval idea of ascent to God in the structural progression from Love to Chastity, Death, Fame, Time, and Eternity. Here Petrarch programmatically counters Dante, transforming a universal, eschatological vision into a subjective, cultural and psychological experience
Fabio Tronchetti
Fabio Tronchetti is an Associate Professor of Law at the School of Law of the Harbin Institute of Technology, People’s Republic of China, where he also serves as Director of the International Law Department. Since January 2014 he works as an Adjunct Professor of Comparative National Space Law at the the School of Law of the University of Mississippi, United States. Earlier in his career he was Lecturer and Academic Coordinator at the International Institute of Air and Space Law, Leiden University, the Netherlands.
Professor Tronchetti is regularly invited to give lectures at several European and Chinese Universities, including the Cologne University (Germany), the Leiden University (the Netherlands) and the Beihang University (Beijing, China) and has participated as a speaker at numerous international conferences.
Prof. Tronchetti’s scholarly is primarily in the areas of international space law and public international law. His publications include two books and more than 20 articles in internationally peer-reviewed space law and policy journals, such as Space Policy, the German Journal of Air and Space Law, the Journal of Space Law, etc.
He holds a PhD in International Space Law (Leiden University) and an Advanced LL.M in International Relations (Bologna University, Italy). He is Member of the International Institute of Space Law (IISL), European Centre for Space Law (ECSL), and the Asian Society of International Law (ASIL). He is the recipient of the 2007 Diederiks-Verschoor award for the best paper submitted by an author not older than 40 years to the International Institute of Space Law (IISL) during the 58th International Astronautical Congress of the International Astronautical Federation (IAF).https://commons.erau.edu/stm-images/1076/thumbnail.jp
