The entero-mammary pathway is a specialized route that selectively translocates bacteria to the newborn's gut, playing crucial role in neonatal development. Previous studies report shared bacterial and archaeal taxa between human milk intestine. However, functional implications for development are not fully understood due limited evidence. This study aimed identify characterize microbiota metabolome of milk, mother, infant stool samples using high-throughput DNA sequencing FT-ICR MS...
New equipment has been designed and constructed to simultaneously measure dynamic viscosity density on the basis of capillary flow technique vibrating tube method, respectively, up 70 MPa 423.15 K. This apparatus built taking into account a number physical parameters such as volumetric flow, length, inner radius border effects. On results this work, densities for liquids are measured with relative combined expanded uncertainties 0.07 % water ethanol, 0.7 hexane, 0.2 heptane, 0.17 1-pentanol...
New experimental data of the dynamic viscosity and density pentane, octane, nonane, decane, dodecane are reported. The method was validated by determining comparing decane with previously published in international literature, obtaining a maximum deviation 12 μPa·s 0.35 kg·m–3 for density, respectively. measurements were performed simultaneously using capillary tube viscometer vibrating densimeter at temperatures between 293 353 K pressures up to 30 MPa. estimated relative combined expanded...
Experimental data of dynamic viscosity (η) and density (ρ) pure alcohols (1-butanol, 1-pentanol, 1-heptanol, 1-octanol 1-nonanol) are presented in the temperature range from (293.15 to 323.15) K pressures up 30 MPa. The were obtained simultaneously, a capillary tube viscometer was used measure coupled with vibrating densimeter where is obtained. expanded uncertainties (k = 2) reported estimated considering impurities samples 0.90% 0.10% for measurements, respectively. Also, this study...
A Mexican natural zeolite (MNZ) was impregnated with Fe at concentrations of 5 and 10 mg FeCl 3 /g MNZ (MNZ/Fe) in order to study the photo-Fenton degradation Reactive Black (RB5) dye. Two samples were prepared calcined 550 700°C for each concentration. These also characterized by following techniques: X-ray diffraction (XRD) determine crystalline phases mineral, photoelectron spectroscopy (XPS) observe elemental composition material where main element as Fe2p, Mössbauer establish which...
Hydrate equilibrium conditions of carbon dioxide in the presence hexane aqueous solutions 1-propanol/tetra-n-butyl ammonium bromide (TBAB) have been studied this Article. The hydrate dissociation water + CO2 1-propanol and TBAB systems measured 271.21–290.77 K 1.21–3.57 MPa temperature pressure ranges, respectively, using an isochoric pressure-search method (synthetic nonvisual method). mass fractions were 0.05, 0.09, 0.30, while 0.10 0.30 for 0.09 0.19. H2O system are compared with...
Natural zeolite is a widely used material with excellent environmental cleaning performance, especially in water and wastewater treatment. (Zini) calcined by CO2-laser radiation (ZL) was tested as catalyst for the photodegradation adsorption of industrial azo dye Lanasol Yellow 4G (LY4G) water. Morphology, chemical structure, surface composition Zini ZL were analyzed XRD, SEM, EDS, XPS. UV/Visible spectrophotometry to evaluate photocatalytic activity ZL. The studied zeolites associated...

Materiales métodos: Las muestras microbiomas recolectaron Sierra Madre Sur estado Oaxaca. Los...
In 1997, a new thermodynamic laboratory was create from scratch. Throughout 20 years of work, this has performed and reported experimental determinations thermophysical properties, such as phase equilibria (VLE, SLE, SLVE), critical points pure fluids mixtures, volumetric properties (PvT), dynamic viscosities, supercritical fluid extraction (SFE), studies on the formation gas hydrates. Over time, systems have been designed, developed, and/or modified according to experiments. Besides,...
Abstract Quantum chemistry calculations were performed to elucidate the reaction sites and degradation routes of dexamethasone. Flow Injection Analysis Electrospray Fourier‐Transform Ion Cyclotron Resonance Mass Spectrometry (FIA‐ESI‐FTCIR‐MS) was used identify dexamethasone its byproducts in Mexico City's wastewater, guided by results from ab‐initio on bond energy analysis thus propose possible routes. Products hydroxylation/reduction, decarbonylation/formylation defluorination reactions...
