Reduction over condensation of carbonyl compounds through a transient hemiaminal intermediate using hydrazine
(American Chemical Society, 2020)
Reduction of carbonyl moieties to the corresponding alcohol using simply hydrazine hydrate has been considerably unfeasible until now due to the well-known condensation reaction. However, herein, we report that using an ...
The alkaline silica-saturated ultrapotassic magmatism of the Riacho do Pontal Fold Belt, NE Brazil: an example of syenite–granite Neoproterozoic association
(Journal of South American Earth Sciences, 2000)
The Neoproterozoic of northeastern Brazil was marked by the development of collisional fold belts, mainly surrounding the Sa˜o Francisco
Craton, and an associated widespread granitic magmatism. The Casa Nova 555 ^ 10 Ma; ...
Brasiliano-age granitoids in the Sergipana Fold Belt, NE Brazil: the Coronel João Sá Pluton
(1998)
The Coronel João Sá pluton is a zoned Brasiliano-age, late- to post-tectonic intrusion in the Macururé schist domain of the Sergipana Foldbelt, Northeast Brazil. Biotite-hornblende granodiorite predominates, and flattened ...
Stress field and active faults in the orogenic front of the Andes in the Malargüe fold-and-thrust belt (35°–36°S)
(Elsevier Science, 2019-09)
We integrate field and wellbore data to discuss the stress field in the frontal sector of the Malargüe fold-and-thrust belt (Andes of Argentina). Surface observations indicate N-S thrusts and NW to WNW and ESE strike-slip ...
Effect of biosynthetic intermediates and citrate on the phenyllactic and hydroxyphenyllactic acids production by Lactobacillus plantarum CRL 778
(Wiley Blackwell Publishing, Inc, 2011-12)
Aim: To evaluate the influence of biosynthetic precursors, intermediates and electron acceptors on the production of antifungal compounds [phenyllactic acid (PLA) and hydroxyphenyllactic acid (OH-PLA)] by Lactobacillus ...
Overexpression and refolding of the hydrophobic ribosomal P0 protein from Trypanosoma cruzi: A component of the P1/P2/P0 complex
(Academic Press Inc Elsevier Science, 2001-06)
The P0 protein is part of the ribosomal eukaryotic stalk, which is an elongated lateral protuberance of the large ribosomal subunit involved in the translocation step of protein synthesis. P0 is the minimal portion of the ...
Ribosomal internal transcribed spacer 2 (ITS2) exhibits a common core of secondary structure in vertebrates and yeast
(Oxford University Press, 1999-12)
Molecular mechanisms of ITS2 processing, a eukaryotic insertion between the 5.8S and LSU rRNA, remain largely elusive even in yeast. To delineate ITS2 structural and functional features which could be common to eukaryotes, ...
Energy self-supply estimation in intermediate cities
(2020)
© 2020 Elsevier Ltd Cities are responsible for more than three quarters of greenhouse gas emissions due to their intensive use of fossil resources. Hence, proposals to modify the current urban energy model have been ...
Contributions to the Morphology of Plectrohyla mykter (Anura: Hylidae), with Comments on Some Controversial Characters and the Diagnosis of this Species
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Instituto de Ciencias Naturales, 2015-01-01)
We describe the tadpole, juveniles, and two adult specimens of Plectrohyla mykter. The tadpole of this species is unique among Plectrohyla by having labial tooth row formula 4(4)/6. We found that tarsal fold, thoracic fold, ...
