The PhoP/PhoQ System and Its Role in Serratia marcescens Pathogenesis
(American Society for Microbiology, 2012-06)
Serratia marcescens is able to invade, persist, and multiply inside nonphagocytic cells, residing in nonacidic, nondegradative, autophagosome-like vacuoles. In this work, we have examined the physiological role of the ...
Site-Specific Structural Constraints on Protein Sequence Evolutionary Divergence: Local Packing Density versus Solvent Exposure
(Oxford University Press, 2013-10)
Protein sequences evolve under selection pressures imposed by functional and biophysical requirements, resulting in site-dependent rates of amino acid substitution. Relative solvent accessibility (RSA) and local packing ...
Water use in rain-fed farming at different scales in the Pampas of Argentina
(Elsevier, 2012-06)
Water use in farming will be an issue of increasing global concern since competition for freshwater among sectors will grow, especially in a water-scarce scenario. Understanding how farming system configurations at different ...
Bone-repair properties of biodegradable hydroxyapatite nano-rod superstructures
(Royal Society of Chemistry, 2015-10)
Nano-hydroxyapatite (nano-HAp) materials show an analogous chemical composition to the biogenic mineral components of calcified tissues and depending on their topography they may mimic the specific arrangement of the ...
Detection of Organic Vapors Using Tamm Mode Based Devices Built from Mesoporous Oxide Thin Films
(Wiley VCH Verlag, 2019-10)
In this work, Tamm mode based devices were synthesized using mesoporous thin films as building blocks. Several systems were designed and built, based on silicon and titanium mesoporous oxides obtained through amphiphilic ...
Bromide counterion as a spectroscopic sensor at the interface of cetyltrimethylammonium micelles
(Pergamon-Elsevier Science Ltd, 2019-12-05)
The strong UV absorption of the bromide in aqueous solution undergoes a remarkable red shift of more than 10 nm induced by the addition of the salts that constitute a saline buffer. The maximum absorption wavelength of the ...
Interaction between natural magnetite sub-micrometric particles and the Fasciola hepatica egg: The role of the exposed surface area
(Academic Press Inc Elsevier Science, 2019-04)
Fasciolosis is a zoonotic world widely distributed disease caused by the liver fluke Fasciola hepatica, which affects animals and occasionally humans. On the other hand, natural iron oxide particles like magnetite are ...
An EIS based study of a Ni-MH battery prototype. Modeling and identification analysis
(Pergamon-Elsevier Science Ltd, 2010-06)
Modeling and simulation of the dynamics of batteries is a useful method to improve design and predict their performance. This paper outlines the development of a simple physicochemical model to simulate the impedance ...
Spectroelectrochemical examination of the interaction between bacterial cells and gold electrodes
(American Chemical Society, 2007-05)
The interaction between bacterial cells of Pseudomonas fluorescens (ATCC 17552) and gold electrodes was analyzed by cyclic voltammetry (CV) and attenuated total reflection-surface-enhanced infrared absorption spectroscopy ...
Spin chains for robust state transfer: Modified boundary couplings versus completely engineered chains
(American Physical Society, 2012-01)
Quantum state transfer in the presence of static disorder and noise is one of the main challenges in building quantum computers. We compare the quantum state transfer properties for two classes of qubit chains under the ...
