Stationary states in a potential well
(UNESCO, 2007)"In the early days of the 20th century a set of important observations in atomic and molecular physics could not be explained on the basis of the laws of classical physics. One of the main findings was the emission of light ... -
Phthalates affect the in vitro expansion of human hematopoietic stem cell
(Springer, 2019)"Phthalates are esters of phthalic acid used industrially as plastic additives, however, these are not covalently bound to the polymer matrix and therefore can be released to the environment. The aim of this study was to ... -
Diisononyl Phthalate differentially affects sirtuin expression in the HepG2 cell line
(American Chemical Society, 2019)"Human exposure to phthalates has received special attention due to their possible adverse human health effects. Diisononyl phthalate (DINP) is a plasticizer still widely used in many products, despite being considered an ... -
Radius evolution for bubbles with elastic shells
(Elsevier, 2021)"We present an analysis of an extended Rayleigh–Plesset (RP) equation for a three dimensional cell of microorganisms such as bacteria or viruses in some liquid, where the cell membrane in bacteria or the envelope (capsid) ... -
Estimating entropy rate from censored symbolic time series: A test for time-irreversibility
(American Institute of Physics, 2021)"In this work, we introduce a method for estimating the entropy rate and the entropy production rate from a finite symbolic time series. From the point of view of statistics, estimating entropy from a finite series can be ... -
Co-production of ethanol-hydrogen by genetically engineered Escherichia coli in sustainable biorefineries for lignocellulosic ethanol production
(Elsevier, 2021)"This work shows the impact of the hydrogen and ethanol co-production –via dark fermentation– using a genetically engineered Escherichia coli in the environmental and economic sustainability of a lignocellulose-based ... -
Catalytic conversion of 5-hydroxymethylfurfural (5-HMF) over Pd-Ru/FAU zeolite catalysts
(Elsevier, 2021)"We present this study on FAU-type zeolites were prepared varying the Si/Al ratio (4, 5 and 6) and crystallization time (4, 6 and 8?h) to produce a highly pure and homogeneous material with enhanced surface area values. ... -
Biodegradation of diisononyl phthalate by a consortium of saline soil bacteria: optimisation and kinetic characterisation
(Springer, 2021)"Diisononyl phthalate (DINP) is one of plasticisers most employed in the production of plastic materials and belongs to the most important environmental contaminants. In this work, a consortium of saline soil bacterial ... -
Multifractal analysis of the symmetry of a strictly isospectral energy landscape on a square lattice
(Elsevier, 2021)"We use the Höder regularity analysis to study the symmetry breaking and recovery due to a parametric potential generated via the strictly isospectral factorization method. The initial potential is two-dimensional and ... -
Biocompatibility of nitrogen-doped multiwalled carbon nanotubes with murine fibroblasts and human hematopoietic stem cells
(Springer, 2019)Chemical vapor deposition (CVD) methods to create carbon nanotubes (CNTs) with specific dopant atoms have been of interest in biomedical applications due to the relative ease of synthesis of doped CNTs with controlled ... -
Diminution of migration of phthalic acid esters in tequila beverage by the year of production
(Taylor & Francis, 2020)"The presence of diethyl-phthalate (DEP), dibutyl-phthalate (DBP), butylbenzyl-phthalate (BBP), diethylhexyl-phthalate (DEHP) and diisononyl-phthalate (DINP) was determined in 295 tequila samples. They were grouped by age ... -
Consensus Stability of a Large Scale Robotic Network under Input and Transmission Delays
(IEEE, 2021)"A large scale network of differential-wheeled robots seeking consensus is considered in the presence of input and transmission delays. Consensus stability of this nonlinear network dynamics holds if its linear part can ... -
Coproduction of hydrogen, ethanol and 2,3-butanediol from agro-industrial residues by the Antarctic psychrophilic GA0F bacterium
(Elsevier, 2020)"In this study, the simultaneous production of hydrogen, ethanol, and 2,3-butanediol was assessed using three agro-industrial residues: cheese whey powder (CWP), wheat straw hydrolysate (WSH) and sugarcane molasses (SCM), ... -
Autodisplay of an endo-1,4-?-xylanase from Clostridium cellulovorans in Escherichia coli for xylans degradation
(Elsevier, 2021)"In this work, the scale-up from 0.01 to 10 L process for the co-production of hydrogen (H2) and ethanol (EtOH) by a genetically engineered Escherichia coli that utilizes hemicellulosic hydrolysates from wheat straw ... -
Scale-up of hydrogen and ethanol co-production by an engineered Escherichia coli
(Elsevier, 2021)"In this work, the scale-up from 0.01 to 10 L process for the co-production of hydrogen (H2) and ethanol (EtOH) by a genetically engineered Escherichia coli that utilizes hemicellulosic hydrolysates from wheat straw ... -
Autodisplay of alpha amylase from Bacillus megaterium in E. coli for the bioconversion of starch into hydrogen, ethanol and succinic acid
(Elsevier, 2020)"In this work, the expression of an alpha-amylase from Bacillus megaterium on the cell surface of Escherichia toll strains WDHA (Delta hycA and Delta ldhA) and WDHFP (Delta hycA, Delta frdD and Delta pta) by the autodisplay ... -
Superfluid Rayleigh–Plesset extension of FLRW cosmology
(Elsevier, 2021)"Guided by the analogy with the Rayleigh–Plesset dynamics of multielectron bubbles in superfluid He-4, we consider the cosmological FLRW evolution equation with additional cubic and sixth powers of the inverse of the scale ... -
