Kinetic and equilibrium adsorption parameters estimation based on a heterogeneous intraparticle diffusion model

In this work, a commercial resin with a well-developed internal pore structure was chosen to adsorb four parabens used as probe molecules. The main novelty was to propose and validate a phenomenological transient adsorption model based on conservation law in both phases coupled with Langmuir’s equilibrium law and Fick’s mass transfer rate law inside the pores. With such an aim, a heterogeneous three-parameter intraparticle diffusion model, IPDM, was formulated, and its numerical solution was fitted to time-dependent concentration data by minimizing the sum of squared residuals. Equilibrium constants were also predicted by fitting Langmuir isotherm to equilibrium data. A monolayer capacity of 0.81 mmol/g was calculated for the four parabens regardless of the number of carbons in the ester group. With the optimal parameters values from the IPDM fitting process, a system of ODEs comprising local sensitivity coefficients as dependent variables was solved to compute the parameters’ variance-covariance matrix and infer their ranges for a 95% marginal confidence interval. In order to test the validity of the proposed model, an attempt to crosscheck between the parameters obtained by the estimation of the equilibrium related parameter, κ, and the modified capacity parameter, and the ones obtained by fitting the Langmuir’s isotherm to equilibrium data was carried out. As far as equilibrium related parameters concern, there is a relative agreement inside the limits of the confidence range between the estimated values of the amount adsorbed in equilibrium with initial bulk solution concentration, q0, and Langmuir’s equilibrium constant, K, adjusted to kinetic and equilibrium data, independently. Additionally, the order of magnitude of pore diffusivity obtained in this work is in accordance with the one predicted by Wilke-Chang correlation and is inversely proportional to the van der Waals volume raised to the power 0.53 in close agreement with the literature.The authors gratefully acknowledge financial support of this research work through the Comisión Interministerial de Ciencia y Tecnología (CICYT)-CTM2013-41354-R and Fundação para a Ciência e a Tecnologia (FCT)-UIDB/04730/2020 projects.info:eu-repo/semantics/publishedVersio

Effect of confinement by SARS-CoV-2 on the degree of steatohepatitis in university students from Reynosa, Tamaulipas

Introduction: Healthy lifestyles are relevant for several diseases, steatohepatitis, although little known, is common in young people. There are reasons to be concerned about homebound college youth who are at risk for steatohepatitis. By restricting the mobility of the population, the risk factors for weight gain and the intake of calorie-dense foods increase, which are elements associated with steatohepatitis. Objective: To determine the effect of confinement during the COVID-19 pandemic on the degree of steatohepatitis by comparing transient elastography results taken before and after confinement. Method: Longitudinal study. A sample of 114 young university students of random sex was included. The transient elastography technique (FibroScan) was implemented, determining the degrees of steatosis and hepatic fibrosis by performing the test before and after the confinement of the participants. Student´s t-test was used to analyse the differences in the degrees of steatohepatitis before and after confinement. Results: the degrees of steatosis during the first sampling were S0 (52.6%), S1 (14.9%), S2 (5.3%) and S3 (27.2%) (m = 250.89, DE= ± 56.91), in the second sampling were presented S0 (56.1%), S1 (13.2%), S2 (5.3%) and S3 (5.4%) (m = 243.81, DE = ± 52.330), the relation of both samples was (p = 0.131). The results in the degrees of fibrosis in the first sampling were F0 (91.4%), F1 (6.1%). F2 (2.6%) (m= 4.80, DE = ±1.11), in the second F1 (95.6%), F2 (3.5) and F2 (0.9%) (m = 4.33, DE = ±1.16) and the relation of the two sampling was (p= 0.000). Conclusions: The degrees of hepatic fibrosis presented significant changes, on the other hand, steatosis tends to decrease, but the change is not significant, however, it is necessary to investigate with third variables to detect other factors involved in the changes

Oort cloud perturbations as a source of hyperbolic Earth impactors

The observation of interstellar objects 1I/'Oumuamua and 2I/Borisov suggests the existence of a larger population of smaller projectiles that impact our planet with unbound orbits. We analyze an asteroidal grazing meteor (FH1) recorded by the Finnish Fireball Network on October 23, 2022. FH1 displayed a likely hyperbolic orbit lying on the ecliptic plane with an estimated velocity excess of $\sim$0.7 km$\,$s$^{-1}$ at impact. FH1 may either be an interstellar object, indicating a high-strength bias in this population, or an Oort cloud object, which would reinforce migration-based solar system models. Furthermore, under the calculated uncertainties, FH1 could potentially be associated with the passage of Scholz's binary star system. Statistical evaluation of uncertainties in the CNEOS database and study of its hyperbolic fireballs reveals an anisotropic geocentric radiant distribution and low orbital inclinations, challenging the assumption of a randomly incoming interstellar population. Orbital integrations suggest that the event on March 9, 2017 (IM2) from CNEOS may have experienced gravitational perturbation during the Scholz fly-by, contingent upon velocity overestimation within the expected range. These findings suggest that apparent interstellar meteors may, in fact, be the result of accelerated meteoroid impacts caused by close encounters with massive objects within or passing through our solar system.Comment: Accepted for publication in Icaru

SUMMARY:The family Pachylaelapidae Vitzthum, 1931, in Tenerife Island (Canarian Archipelago) is represented by Pachyseius humeralis Berlese, 1910, and twelve species of Pachylaelaps, seven of which are new for science - P silviae, P mandibularis, P auricularis, P intermedius, P glandular is, P canariensis and P subkarawaiewi. P longisetis, Halbert, 1915, P brachyperitrematus, Koroleva, 1977, P regularis, Berlese, 1921 are recorded, and two unknown species which are not considered new, because of the absence of female specimens, are described. The ontogeny and notation of the dorsal chaetotaxy is discussed.RESUMEN:La familia Pachylaelapidae Vitzthum, 1931, esta representada en 1a isla de Tenerife (Archipielago Canario) por Pachyseius humeralis Ber1ese, 1910 y doce especies del genero Pachylaelaps, siete de 1as cuales se describen como nuevas para la ciencia - P silviae, P mandibularis, P auricularis, P intermedius, P glandularis, P canariensis y P subkarawaiewi.

Molecular dynamics simulation of surface phenomena due to high electronic excitation ion irradiation in amorphous silica

We studied by means of an atomistic model based on molecular dynamics the thermal evolution of surface atoms in amorphous silica under high electronic excitation produced by irradiation with swift heavy ions. The model was validated with the total and differential yields measured in sputtering experiments with different ions and ion energies showing a very good quantitative prediction capability. Three mechanisms are behind the evolution of the surface region: (1) an ejection mechanism of atoms and clusters with kinetic energy exceeding their binding energy to the sample surface, which explains the experimentally observed angular distributions of emitted atoms, and the correlation of the total sputtering yield with the electronic stopping power and the incidence angle. (2) A collective mechanism of the atoms in the ion track originated by the initial atom motion outwards the track region subsequently followed by the return to the resulting low-density region in the track center. The collective mechanism describes the energy dissipation of bulk atoms and the changes in density, residual stress, defect formation and optical properties. (3) A flow mechanism resulting from the accumulation and subsequent evolution of surface atoms unable to escape. This mechanism is responsible for the crater rim formation.Open Access funding provided thanks to the CRUE-CSIC agreement with Springer Nature.
