Non-canonical roles of tRNAs and tRNA mimics in bacterial cell biology
(Wiley-Blackwell, 2016)
Transfer RNAs (tRNAs) are the macromolecules that transfer activated amino acids from aminoacyl-tRNA synthetases to the ribosome, where they are used for the mRNA guided synthesis of proteins. Transfer RNAs are ancient ...
Probing the hydride transfer process in the lumiflavine-1- methylnicotinamide model system using group softness
(2004)
The hydride transfer process between the isoalloxazine moiety of flavins and the nicotinamide moiety of NAD(P)H has been explored by using density functional theory based reactivity index in the 1-methylnicotinamide-lumiflavine ...
Functionality of tRNAs encoded in a mobile genetic element from an acidophilic bacterium
(Taylor and Francis Inc., 2018)
© 2018, © 2018 Taylor & Francis Group, LLC. The genome of the acidophilic, bioleaching bacterium Acidithiobacillus ferrooxidans, strain ATCC 23270, contains 95 predicted tRNA genes. Thirty-six of these genes (all 20 species) ...
Effect of soil structure interaction on the dynamic responses of base isolated bridges and comparison to experimental results
(Elsevier Ltd, 2018)
In this paper, the effect of soil structure interaction and base isolation on the dynamic characteristics of an instrumented bridge is examined using transfer functions and measured motions in the frequency domain. A three ...
On the Reaction Mechanism of the Complete Intermolecular O2 Transfer between Mononuclear Nickel and Manganese Complexes with Macrocyclic Ligands
(Chemistry - A European Journal, 2018)
Hydrogen bonding and dissociation effects on the gas phase proton transfer reactions of ozone
(Springer New York LLC, 1998)
© Springer-Verlag 1998. Recently, the proton affinity (PA) of ozone was experimentally determined by Cacace and Speranza [Science (1994) 265: 208] using a bracketing technique that involved the proton transfer (PT) reactions: ...
ELECTRONIC SYSTEM FOR EXPERIMENTATION IN AC ELECTROGRAVIMETRY I: TECHNIQUE FUNDAMENTALS
(Fondo Editorial EIA - Universidad EIA, 2013-10-07)
Basic fundamentals of AC electrogravimetry are introduced. Their main requirements and characteristics are detailed to establish the design of an electronic system that allows the appropriate extraction of data needed to ...
Theoretical study of conformational aspects, excited states and directional energy transfer: The Terphenylene, Diphenylhexatriene and Quinquethiophene triad included in PHTP nanochannels
(Elsevier, 2011-04)
The limited one-dimensional space of nanochannels of the supramolecular Perhydrotriphenylene (PHTP) matrix host induce changes on the structure of included molecules that affect some of their properties. A combination of ...
The value of information in cooperative environment
(Universidad de Chile. Facultad de Economía y Negocios, 2003-12)
In this paper we analyze the value of the information in a cooperative game.
There is a player, the innovator, having a know how or relevant information
which is not useful for himself but it can be sold to some potential ...
Implementation of transfer trip schemes in numerical overcurrent relays.
(2011-10-13)
Numerical protection devices are much more than just relays. Actually they are small computers with protective functions complemented with others like control, metering, logic, logging and communication. These functions ...
