Electrochemical Characterization of Mass Transport at Microelectrode Arrays
Authors: Torres Hernández Walter 
Published: November 2017

Electrodes with dimensions in the micro- and nano-meter scale can be used as analytical probes in confi ned places such as cells and organelles. Arrays of microelectrodes, particularly disk-shaped electrodes, are now a platform to fabricate electrochemical sensors and multisensors. A useful characteristic of such arrays is that enhancement of the current signal is due to the fact that radial diffusion becomes important as the disk radius gets smaller and steady state currents are attainable in a relatively short time. Because there is no general analytical solution for the current response at MEAs, previous characterization of any micro electrode array at hand is still required. This paper discusses the electrochemical characterization of the mass transport of a reversible electrochemical probe at a commercially available micro-disk electrode array by two commonly used tools for electro analysis, namely: cyclic voltammetry and chronoamperometry. The questions to be addressed are whether clear radial diffusion control can be effectively achieved and the time required for the electrode system to reach steady state. For chronoamperometric experiments, the current response almost achieves steady state in the time range between 0.49 s and 1 s. This is precisely the time bracket in which analytical measurements should be made in order to achieve high sensitivity.

Los constituyentes del suelo (arcillas, carbonatos, materia orgánica y óxidos e hidróxidos), intervienen en la movilidad del arsénico (As) y determinan su variación espacial; por lo cual, su cartografía puede contribuir al entendimiento de la presencia de este metaloide en el suelo. Los objetivos de esta investigación fueron determinar la concentración de As en los suelos del Distrito de Riego 017 (DR017) de México y establecer su distribución espacial, utilizando dos métodos de interpolación. Cuatro etapas fueron realizadas; la primera consistió en trabajo de gabinete y campo, en la que 33 sitios de muestreo fueron localizados en un polígono del DR017, posteriormente en cada sitio, muestras simples de suelo (0-30 cm de profundidad) fueron colectadas. La segunda y tercera se llevaron a cabo en laboratorio, en las cuales, a cada muestra se determinó la concentración de As disponible, contenidos de arcilla, carbonatos de calcio y fósforo disponible y su regresión. La cuarta etapa tuvo dos partes, la elaboración de dos mapas con dos métodos de interpolación (Interpolador Ponderación Inversa de la Distancia, IDW en sus siglas en inglés y Kriging ordinario, KO), así como la verif icación de la precisión de cada mapa. Los resultados mostraron que, la distribución del As en el DR017 no es uniforme y está asociada con el contenido de arcilla y CaCO3. De tal manera que, las concentraciones de As fluctuaron de 0.07 a 1.89 mg kg-1, donde las mayores concentraciones de este metaloide (1.39-1.89 mg kg‑1) se relacionaron positivamente (R2 = 0.9058) con altos contenidos de arcilla (39.44 a 43.44%). El mapa de distribución espacial de As obtenido con KO, tuvo la mayor precisión (75.7%), en el cual se muestra que la concentración aumenta en un sentido sur-norte, donde el área de mayor concentración está en la parte norte del distrito.

El uso de variedades mejoradas, así como biofertilizantes elaborados con hongos micorriza favorecen la nutrición y permiten complementar el uso de fertilizantes químicos, lo que podría incrementar la producción. El objetivo de este trabajo fue determinar el rendimiento de grano de los híbridos por efecto de la aplicación, y testigo sin aplicar, de micorriza (Glomus intraradices), en cinco híbridos de maíz en sus versiones fértiles y androestériles. La evaluación se realizó por medio de cuatro experimentos, dos ubicados en la Facultad de Estudios Superiores FES Cuautitlán-UNAM y dos en el Campo Experimental del Valle de México CEVAMEX - INIFAP, en Texcoco, México. Se utilizó un diseño de bloques completos al azar con cuatro repeticiones; las siembras de los materiales se efectuaron en la segunda quincena de mayo y primera de junio de 2012. El análisis estadístico de los datos fue factorial, donde los factores principales fueron ambientes, genotipos, androesterilidad/fertilidad, aplicación o no de biofertilizante, así como las interacciones de los mismos. En los rendimientos se detectó signif icancia debido a los ambientes y genotipos, no así para ningún otro factor o interacciones. La media general del rendimiento fue de 8294 kg ha1. El rendimiento obtenido en la segunda fecha de siembra en la FES Cuautitlán-UNAM fue de 9939 kg ha-1, siendo superior al de la fecha 1 del CEVAMEX (6071 kg ha‑1). No hubo efecto de la aplicación de micorriza en el rendimiento medio de los híbridos (8310 kg ha-1), el cual fue similar al del testigo sin aplicación de micorriza (8279 kg ha-1). El genotipo con mayor rendimiento fue Tsíri PUMA, con 9557 kg ha-1, y resultó diferente estadísticamente al del H-47 AE (8692 kg ha-1). TSÍRI PUMA I y PUMA 1183 AE rindieron 8687 kg ha-1 y 8150 kg ha‑1, respectivamente. Por otro lado, el rendimiento medio de la versión androestéril de los híbridos fue de 8447 kg ha‑1, siendo similar estadísticamente al promedio de la versión fértil (8142 kg ha-1). Si bien la aplicación de micorriza a la semilla no propició un efecto signif icativo en el rendimiento promedio de los genotipos, es conveniente verif icar en ciclos siguientes en los maíces androestériles y fértiles, con manejo de fechas de siembra diferentes, donde pudiera expresarse el efecto de Glomus intraradices, y contar con mayor información de la respuesta a este biofertilizante.

Las emisiones de carbono (C) a la atmósfera, así como sus reservorios, en el sector de agricultura, silvicultura y otros usos del suelo son signif icativas en el balance global del ciclo del carbono; sin embargo, a pesar de esta importancia, es el sector con la mayor incertidumbre en el balance global debido principalmente a la falta de conocimiento preciso de los factores de emisión, por lo que se requiere mayor investigación en el tema. Debido a lo anterior, este trabajo tuvo como objetivo estimar el C almacenado en los cinco depósitos considerados en ecosistemas forestales: biomasa viva sobre el suelo, biomasa viva debajo del suelo, madera muerta sobre el suelo, mantillo y carbono orgánico del suelo (COS) en dos sitios de muestreo ubicados en las faldas del Monte Tláloc, Texcoco, Estado de México: el primero en un bosque de oyamel (Abies religiosa) y el segundo en un bosque de ciprés (Cupressus lusitanica). El promedio de la densidad de carbono en el bosque de oyamel en los cinco depósitos estimados fue de 376 Mg ha‑1, siendo el depósito más importante el de biomasa aérea (59%), seguido del COS (22%); en tanto que en el bosque de ciprés fue de 205 Mg ha-1, siendo el depósito con mayor densidad el COS (50%), seguido de biomasa aérea (36%). Los valores de densidad de carbono para biomasa aérea en el caso de bosque de oyamel fueron superiores a los reportados en otros trabajos; lo cual se explica por la existencia de árboles de grandes dimensiones de esta especie en el sitio de muestreo, lo cual nos da una idea precisa del potencial como almacén de carbono que este tipo de vegetación tiene cuando llegan a estados maduros.

Published: November 2017

El estilo de vida de los estudiantes univer­sitarios es considerado un factor que favo­rece la ingestión inadecuada de alimentos, ocasionando cambios importantes en su peso corporal. El propósito de la presente investigación fue analizar longitudinalmente la frecuencia de consumo de alimentos, el índice de masa corporal (IMC) y el porcentaje de grasa de jóvenes que ingresan a la univer­sidad. Participaron 96 estudiantes de primer ingreso a una institución pública de educa­ción superior (mujeres = 59 y varones = 37) con una edad promedio de 19.81 años (DE = 2.64). Los jóvenes universitarios contestaron el Cuestionario de Frecuencia de Consumo de Alimento en tres momentos diferentes, con un intervalo de seis meses; también fueron medidos y pesados para obtener el IMC y el porcentaje de grasa. Los resultados del ANO­VA mostraron que el IMC aumentó significativamente entre el primer y segundo tiempo tanto en las mujeres (F = 3.58, P < 0.05) como en los varones (F = 3.01, P < 0.05); el porcentaje de grasa aumentó significativamente en los tres tiempos tanto en las mujeres (F = 4.75, P < 0.05) como en los varones (F = 3.29, P < 0.05). La frecuencia de consumo de grasas-aceites aumentó significativamente entre el primer y segundo tiempo en ambos géneros (F = 2.88, P < 0.05, mujeres; F = 3.71, P < 0.05, varones) y la frecuencia de consumo de azúcares aumentó en cada tiempo para ambos géneros (F = 6.45, P < 0.001, mujeres; F = 7.85, P < 0.001, varones). Estos hallazgos muestran que se modificó el IMC, el porcentaje de grasa y la frecuencia de consumo de alimentos de los jóvenes, siendo relevante el cambio en los primeros meses de su ingreso a la universidad.

Published: November 2017

Abstract
A novel slit die with an adjustable gap is designed to perform transient swell measurements while changing the die gap dynamically. A generalized control model is developed to predict time-dependent swell using characteristic relaxation time and corresponding steady state swell as model parameters. Further, a series of slit dies are designed and used to measure steady state thickness swell of a high-molecular-weight blow-molding grade high density polyethylene resin under various operating and geometrical conditions. A generalized expression for steady state thickness swell is obtained by applying multi-variable nonlinear regression on thus obtained steady state thickness swell data, and is used in the empirical control model to predict transient extrudate swell.
Rheological In-Mold Measurements and Characterizations of Sheet-Molding-Compound (SMC) Formulations with Different Constitution Properties by Using a Compressible Shell Model

Published: November 2017

Abstract
The rheological characterization of Sheet Molding Compound (SMC) and its modelling is crucial for reliable process simulations. In the past, characterization and material modelling were mainly focusing on SMC with low glass fiber content and a high filler fraction. Due to new application areas, SMC without fillers and with high glass fiber contents, and SMC with carbon fibers become more important. Therefore, these three types of SMCs are characterized in this work, using an inline rheological tool. Differences regarding their compressibility and their flow dependency are identified and considered in an analytical shell modelling. The comparison of the different materials leads to a better understanding of the phenomenological parameters related to the viscosity and friction in the models. Furthermore, the importance to properly consider all relevant material-specific effects becomes evident.

Abstract
Galactic X-ray binary black hole candidate Swift J1753.5-0127 was discovered on 2005 June 30 by the Swift/BAT instrument. In this paper, we make a detailed analysis of spectral and timing properties of its 2005 outburst using the archival data of the RXTE/PCA instrument. A simultaneous observation of Swift/XRT with PCA is also used to study the broadband features. Here, we study the evolution of the spectral properties of the source from spectral analysis with an additive table model fits file of the Chakrabarti-Titarchuk two-component advective flow (TCAF) solution. From the spectral fit, we extract physical flow parameters, such as the Keplerian disk accretion rate, sub-Keplerian halo rate, shock location, and shock compression ratio, etc. We also study the evolution of temporal properties, such as the observation of low-frequency quasi-periodic oscillations (QPOs), and the variation of X-ray intensity throughout the outburst. From the nature of the variation of QPOs, and accretion rate ratios (ARRs = ratio of halo to disk rates), we classify the entire 2005 outburst into two harder (hard-intermediate and hard) spectral states. No signatures of softer (soft-intermediate and soft) spectral states are seen. This may be because of a significant halo rate throughout the outburst. This behavior is similar to a class of other short-orbital-period sources, such as MAXI J1836-194, MAXI J1659-152, and XTE J1118+480. We estimate the probable mass range of the source to be in between

based on our spectral analysis.
Discovery of Diffuse Dwarf Galaxy Candidates around M101

Published: November 2017

Abstract
We have conducted a search of a 9 deg2 region of the Canada–France–Hawaii-Telescope Legacy Survey around the Milky Way analog M101 (D ∼ 7 Mpc), in order to look for previously unknown low-surface-brightness galaxies. This search has uncovered 38 new low-surface-brightness dwarf candidates, and confirmed 11 previously reported galaxies, all with central surface brightness μ(g, 0) > 23 mag arcsec−2, potentially extending the satellite luminosity function for the M101 group by ∼1.2 mag. The search was conducted using an algorithm that nearly automates the detection of diffuse dwarf galaxies. The candidates’ small sizes and low surface brightnesses mean that the faintest of these objects would likely be missed by traditional visual or computer detection techniques. The dwarf galaxy candidates span a range of −7.1 ≥ M

g
≥ −10.2 and half-light radii of 118–540 pc at the distance of M101, and they are well fit by simple Sérsic surface brightness profiles. These properties are consistent with dwarfs in the Local Group, and to match the Local Group luminosity function, ∼10–20 of these candidates should be satellites of M101. Association with a massive host is supported by the lack of detected star formation and the overdensity of candidates around M101 compared to the field. The spatial distribution of the dwarf candidates is highly asymmetric, and concentrated to the northeast of M101, therefore distance measurements will be required to determine if these are genuine members of the M101 group.

Abstract
The Planck cosmic microwave background temperature data are best fit with a ΛCDM model that mildly contradicts constraints from other cosmological probes. The South Pole Telescope (SPT) 2540

SPT-SZ survey offers measurements on sub-degree angular scales (multipoles

) with sufficient precision to use as an independent check of the Planck data. Here we build on the recent joint analysis of the SPT-SZ and Planck data in Hou et al. by comparing ΛCDM parameter estimates using the temperature power spectrum from both data sets in the SPT-SZ survey region. We also restrict the multipole range used in parameter fitting to focus on modes measured well by both SPT and Planck, thereby greatly reducing sample variance as a driver of parameter differences and creating a stringent test for systematic errors. We find no evidence of systematic errors from these tests. When we expand the maximum multipole of SPT data used, we see low-significance shifts in the angular scale of the sound horizon and the physical baryon and cold dark matter densities, with a resulting trend to higher Hubble constant. When we compare SPT and Planck data on the SPT-SZ sky patch to Planck full-sky data but keep the multipole range restricted, we find differences in the parameters n

and

. We perform further checks, investigating instrumental effects and modeling assumptions, and we find no evidence that the effects investigated are responsible for any of the parameter shifts. Taken together, these tests reveal no evidence for systematic errors in SPT or Planck data in the overlapping sky coverage and multipole range and at most weak evidence for a breakdown of ΛCDM or systematic errors influencing either the Planck data outside the SPT-SZ survey area or the SPT data at
