Eficiencia del tratamiento de los lixiviados en la infraestructura de tratamiento y disposición final de residuos sólidos de Cajamarca 2021

El presente trabajo determinó la eficiencia del tratamiento de los lixiviados en la infraestructura de tratamiento y disposición de residuos sólidos, la cual se encuentra ubicada en el sector Palturo, caserío de San José de Canay, distrito de Jesús; provincia y departamento de Cajamarca en el año 2021. La toma de muestras fue realizada en las pozas de los lixiviados sin tratamiento y de las pozas tratadas, el tratamiento se realiza con hidróxido de calcio Ca (OH)₂ y recirculación, se tomó un total de cuatro muestras en dos periodos, época seca y de lluvia. Los ensayos fueron realizados por el Laboratorio Regional del Agua de Cajamarca, los resultados que se pudieron obtener a partir del análisis a nivel fisicoquímico y microbiológico, se presentan en los informes IE 0821629 - I, IE 1221744-I; Los parámetros identificados de arsénico, cromo, plomo, zinc y pH no tienen cambio significativo entre el ingreso y salida, en el caso de hierro, sólidos suspendidos totales, existe un incremento en la salida, para la demanda bioquímica de Oxígeno (DBO5) y la (DQO), tienen una remoción de 40.1 % y de 39.5 % esta eliminación es muy baja, en el parámetro microbiológico se tiene una remoción alta de 90 %, sin embargo, no cumple con el valor de referencia del Límite Máximo Permisible. Se concluye que la eficiencia del tratamiento en los lixiviados es deficiente, debido a los procesos realizados en la planta, lo cual no ayuda para el cumplimiento normativo, dado que la prueba Anova obtiene un Sig = 1.000, siendo este valor p>0.05 por ende, se niega la hipótesis alternativa y se da la aceptación de la hipótesis nula

Electrochemical sensors modified with combinations of sulfur containing phthalocyanines and capped gold nanoparticles: A study of the influence of the nature of the interaction between sensing materials

Producción CientíficaVoltametric sensors formed by the combination of a sulfur-substituted zinc phthalocyanine (ZnPcRS) and gold nanoparticles capped with tetraoctylammonium bromide (AuNPtOcBr) have been developed. The influence of the nature of the interaction between both components in the response towards catechol has been evaluated. Electrodes modified with a mixture of nanoparticles and phthalocyanine (AuNPtOcBr/ZnPcRS) show an increase in the intensity of the peak associated with the reduction of catechol. Electrodes modified with a covalent adduct-both component are linked through a thioether bond-(AuNPtOcBr-S-ZnPcR), show an increase in the intensity of the oxidation peak. Voltammograms registered at increasing scan rates show that charge transfer coefficients are different in both types of electrodes confirming that the kinetics of the electrochemical reaction is influenced by the nature of the interaction between both electrocatalytic materials. The limits of detection attained are 0.9 × 10−6 mol∙L−1 for the electrode modified with the mixture AuNPtOcBr/ZnPcRS and 1.3 × 10−7 mol∙L−1 for the electrode modified with the covalent adduct AuNPtOcBr-S-ZnPcR. These results indicate that the establishment of covalent bonds between nanoparticles and phthalocyanines can be a good strategy to obtain sensors with enhanced performance, improving the charge transfer rate and the detection limits of voltammetric sensors.Ministerio de Economía, Industria y Competitividad - Fondo Europeo de Desarrollo Regional (projects RTI2018-097990-B-I00 / CTQ2017-87102-R)Junta de Castilla y Leon - Fondo Europeo de Desarrollo Regional (project VA275P18

Characterization of goat colostrum oligosaccharides by nano-liquid chromatography on chip quadrupole time-of-flight mass spectrometry and hydrophilic interaction liquid chromatography-quadrupole mass spectrometry

A detailed qualitative and quantitative characterization of goat colostrum oligosaccharides (GCO) has been carried out for the first time. Defatted and deproteinized colostrum samples, previously treated by size exclusion chromatography (SEC) to remove lactose, were analyzed by nanoflow liquid chromatography–quadrupole-time of flight mass spectrometry (Nano-LC-Chip–Q-TOF MS). Up to 78 oligosaccharides containing hexose, hexosamine, fucose, N-acetylneuraminic acid or Nglycolylneuraminic acid monomeric units were identified in the samples, some of them detected for the first time in goat colostra. As a second step, a hydrophilic interaction liquid chromatography coupled to mass spectrometry (HILIC-MS) methodology was developed for the separation and quantitation of the main GCO, both acidic and neutral carbohydrates. Among other experimental chromatographic conditions, mobile phase additives and column temperature were evaluated in terms of retention time, resolution, peak width and symmetry of target carbohydrates. Narrow peaks (wh: 0.2–0.6 min) and good symmetry (As: 0.8–1.4) were obtained for GCO using an acetonitrile:water gradient with 0.1% ammonium hydroxide at 40 ◦C. These conditions were selected to quantify the main oligosaccharides in goat colostrum samples. Values ranging from 140 to 315 mg L−1 for neutral oligosaccharides and from 83 to 251 mg L−1 for acidic oligosaccharides were found. The combination of both techniques resulted to be useful to achieve a comprehensive characterization of GCO.This work has been funded by Junta de Andalucía (project AGR2011-7626), CSIC (project i-link0827), Comunidad Autónoma de Madrid (Spain) and European funding from FEDER program (AVANSECAL-CM S2013/ABI-3028) and Fundación Ramón Areces.

The Usefulness of a Massive Open Online Course about Postural and Technological Adaptations to Enhance Academic Performance and Empathy in Health Sciences Undergraduates

Massive open online courses (MOOCs) provide accessible and engaging information for Physical Therapy and Occupational Therapy students. The objective of this research was to determine the usefulness in improving academic performance and empathy in health sciences undergraduates, and to test a hypothetical model through structural equation analysis. This research was carried out using a descriptive and quasi-experimental design. It was conducted in a sample of 381 participants: 176 used a MOOC and 205 did not. The results of the Student’s t-test showed statistically significant differences in academic performance between the groups in favor of those students who had realized the MOOC. Participants carried out an evaluation rubric after taking MOOC. Statistically significant differences in empathy were also obtained between the pre (X = 62.06; SD = 4.41) and post (X = 73.77; SD = 9.93) tests. The hypothetical model tested via structural equation modeling was supported by the results. Motivation for the MOOC explained 50% of the variance. The MOOC (participation and realization) explained 58% of academic performance, 35% of cognitive empathy and 48% of affective empathy. The results suggest an association between higher realization and participation in a MOOC and higher levels of academic performance, and cognitive and affective empathy.University of Malaga (UMA) for the Call for Educational Innovation Projects (PIE19-148), to the Call 2019-2021Initiation Grant for Research from the UMA's Own Plan, in Modality A (Grade
