Published: May 2017

La investigación expone el caso de las revistas académicas de comunicación de acceso abierto en México, sus antecedentes, estado actual, retos y vicisitudes. Asimismo, considera el número de licenciaturas y posgrados de comunicación en el país, con la idea de reflexionar y relacionar la información con el total de revistas existentes. Metodología: De corte descriptivo, el trabajo se sustenta en la revisión de las publicaciones académicas de acceso abierto que abordan temas de comunicación. Identifica las características que les otorga el adjetivo “académicas”, examina su visibilidad a través de la indexación a las bases de datos, formatos de acceso, utilización del Open Journal Systems (ojs), inclusión del digital object identifier (doi), uso de programas antiplagio, adhesión al Committee on Publication Ethics (Cope), empleo de las licencias Creative Commons y registro de citas en Google Académico, diversidad en los formatos de acceso, entre otros. Resultados y discusión: Se especifica, en dos tablas, el estado actual de las publicaciones de comunicación de acceso abierto en México; se reconoce que las publicaciones existentes son insuficientes, que, paralelamente, coexisten con su versión impresa, y que la versión electrónica está rezagada por los avances tecnológicos y los procesos internacionales de normalización, lo que las deja fuera del interés de algunos connacionales para publicar en ellas. Se reconoce, también, la existencia de revistas avaladas por instituciones educativas, que no tienen precisamente el interés de ser indizadas a las bases de datos nacionales e internacionales, ya que su rol endogámico/institucional les permite, apropiadamente, ser una plataforma de aprendizaje para la formación de académicos que experimentan, por primera vez, el arte de publicar.

ABSTRACTIntroductionWhite spot lesion is the early sign of demineralization occurring under intact enamel which may lead to the development of caries.AimThe aim of this study is to compare and evaluate the caries-preventive efficacy of a resin infiltrant, casein phosphopeptideamorphous calcium phosphate (CPP-ACP), and nanohydroxyapatite (nano-HA) on white spot enamel lesions.Settings and designsA total of 40 freshly extracted human maxillary incisors were used in this study. Enamel samples (2 mm thickness) were prepared and sample preparation windows were created (dimension of 5 × 5 mm) using adhesive tape, and the sample was made completely resistant to acid attack by coating nail varnish.Materials and methodsThe samples were divided into four groups, which are resin infiltrant, CPP-ACP, nano-HA, and control of 10 enamel samples in each group. The samples were evaluated using confocal laser scanning microscopy before and after the application of resin infiltrant and remineralizing agents.Statistical analysisStatistical analysis was done using analysis of variance andpost hocBonferroni test was used for comparing intragroups and Tukey test for comparing intergroups.ResultsThe mean value after demineralization is 245, 246, 250, and 247 μm for Groups I to IV. After remineralization, group I > group II > group III > group IV. After acid challenge for a period of 14 days, group I > group II > group III > group IV.ConclusionThe resin infiltrant showed higher caries inhibition potential and superior acid resistance than CPP-ACP and nano-HA.Clinical significanceThe inhibition of caries progression by resin infiltration technique should be considered as an alternative approach to the more invasive therapies and warrants a place in the range of minimally invasive dentistry techniques.How to cite this articleArvindkumar A, Maheswari U, Kingston C, Gnanaseelan R, Jonathan Emil Sam R.

Abstract
Aim
The aim of the present study is to evaluate the influence of socioeconomic status and social habits on the prevalence of dental caries in Chennai population. Cross sectional study was conducted in 500 patients by survey method using a questionnaire. Data was collected based on demographic details, information on the income, educational qualification, occupation, social habits (tobacco and alcohol consumption) and the caries exposure in terms of presence or absence of dental caries or a restoration. The data was tabulated using Microsoft Excel and statistically analysed using SPSS version 22. 91.8% of subjects in the lower socio economic status have a caries exposure while only 82% and 73.4% of the medium and higher economic status had caries. Within the limitations of the present study it can be concluded that there exists a connection between the individuals' socio economic condition and the oral health status that calls for implementation of oral health programs.

Low planktic foraminiferal diversity and abundance observed in a spring 2013 west–east Mediterranean Sea plankton tow transect
Authors: Mallo Miguel , Ziveri Patrizia , Mortyn P. Graham , Schiebel Ralf , Grelaud Michael 
Published: May 2017

Abstract. Planktic foraminifera were collected with 150 µm BONGO nets from the upper 200 m water depth at 20 stations across the Mediterranean Sea between 2 May and 2 June 2013. The main aim is to characterize the species distribution and test the covariance between foraminiferal area density (ρA) and seawater carbonate chemistry in a biogeochemical gradient including ultraoligotrophic conditions. Average foraminifera abundances are 1.42 ± 1.43 ind. 10 m−3 (ranging from 0.11 to 5.20 ind. 10 m−3), including 12 morphospecies. Large differences in species assemblages and total abundances are observed between the different Mediterranean sub-basins, with an overall dominance of spinose, symbiont-bearing species indicating oligotrophic conditions. The highest values in absolute abundance are found in the Strait of Gibraltar and the Alboran Sea. The western basin is dominated by Globorotalia inflata and Globigerina bulloides at slightly lower standing stocks than in the eastern basin. In contrast, the planktic foraminiferal assemblage in the warmer, saltier, and more nutrient-limited eastern basin is dominated by Globigerinoides ruber (white). These new results, when combined with previous findings, suggest that temperature-induced surface water stratification and food availability are the main factors controlling foraminiferal distribution. In the oligotrophic and highly alkaline and supersaturated with respect to calcite and aragonite Mediterranean surface water, standing stocks and ρA of G. ruber (white) and G. bulloides are affected by both food availability and seawater carbonate chemistry. Rapid warming increased surface ocean stratification impacting food availability and changes in trophic conditions could be the causes of reduced foraminiferal abundance, diversity, and species-specific changes in planktic foraminiferal calcification.

Published: May 2017

Abstract. We compare geocoded heights derived from the interferometric mode (SARIn) of CryoSat to surface heights from calibration–validation sites on Devon Ice Cap and western Greenland. Comparisons are included for both the heights derived from the first return (the point-of-closest-approach or POCA) and heights derived from delayed waveform returns (swath processing). While swath-processed heights are normally less precise than edited POCA heights, e.g. standard deviations of  ∼  3 and  ∼  1.5 m respectively for the western Greenland site, the increased coverage possible with swath data complements the POCA data and provides useful information for both system calibration and improving digital elevation models (DEMs). We show that the pre-launch interferometric baseline coupled with an additional roll correction ( ∼  0.0075° ± 0.0025°), or equivalent phase correction ( ∼  0.0435 ± 0.0145 radians), provides an improved calibration of the interferometric SARIn mode. We extend the potential use of SARIn data by showing the influence of surface conditions, especially melt, on the return waveforms and that it is possible to detect and measure the height of summer supraglacial lakes in western Greenland. A supraglacial lake can provide a strong radar target in the waveform, stronger than the initial POCA return, if viewed at near-normal incidence. This provides an ideal situation for swath processing and we demonstrate a height precision of  ∼  0.5 m for two lake sites, one in the accumulation zone and one in the ablation zone, which were measured every year from 2010 or 2011 to 2016. Each year the lake in the ablation zone was viewed in June by ascending passes and then 5.5 days later by descending passes, which allows an approximate estimate of the filling rate. The results suggest that CryoSat waveform data and measurements of supraglacial lake height change could complement the use of optical satellite imagery and be helpful as proxy indicators for surface melt around Greenland.
Determination of Lutein and β-Carotene in Infant Formula and Adult Nutritionals by Ultra-High-Performance Liquid Chromatography: Single-Laboratory Validation, First Action 2016.13
Authors: Hostetler Gregory L 
Published: May 2017

Abstract
An ultra-HPLC method for the determination of lutein and β-carotene in infant formula and adult nutritionals wasvalidated using both unfortified and fortified samples provided by the AOAC Stakeholder Panel on Infant Formula and AdultNutritionals (SPIFAN). All experiments showed separation of all-trans-lutein and β-carotene from their major cis isomers, apocarotenal, α-carotene, lycopene, and zeaxanthin. Samples spiked with all-trans-lutein and β-carotene showed no isomerization during sample preparation. Linearity of the calibration solutions correlated to approximately 0.8–45 μg/100 g (reconstituted basis) for samples prepared for the lowest sample concentrations. With dilutions specified in the method, the range can be extended to approximately 2250 μg/100 g. The LOD for both lutein and β-carotene was 0.08 μg/100 g, and the LOQ for both was 0.27μg/100 g. For all measurements in the range of 1–100 μg/100 g, repeatability RSD was ≤5.8% forlutein and ≤5.1% for β-carotene. For measurements &gt;100 μg/100 g, repeatability RSD was ≤1.1% for lutein and ≤1.7% for β-carotene. Accuracywas determined by recovery from spiked samples and ranged from 92.3 to 105.5% for lutein and from 100.1 to 107.5% for β-carotene. The data provided show that the method meets the criteria specified in the Standard Method Performance Requirements for carotenoids (SMPR 2014.014).

Abstract
A QuEChERS technique–based sample preparation method was optimized and validated in small cardamom to monitor the residues of 154 pesticides by LC with tandem MS. The proposed multiresidue method involved soaking powdered cardamom (2 g) in water (8 mL) for 30 min, followed by extraction with acetonitrile (10 mL). Cleanup by dispersive SPE was performed using primary secondary amine (25 mg/mL), C18 (25 mg/mL), and anhydrous magnesium sulfate (150 mg/mL). The method was validated as per the SANTE/11945/2015 guidelines at 5, 10, 50, and 100 ng/g spiking levels, and most of the analytes showed recoveries between 70 and 120% (with RSDs ≤20%). The LOQ of ≤10 ng/g was achieved for almost 90% of the target pesticides. The measurement uncertainties were evaluated at 100 ng/g, and the global uncertainty values were below 22% for all the analytes.

Phytostabilization is a remediation technology that uses plants for in-situ stabilization of contamination in soils and mine tailings. The objective of this study was to identify native plant species with potential for phytostabilization of the abandoned mine tailings in Nacozari, Sonora in northern Mexico. A flora of 42 species in 16 families of angiosperms was recorded on the tailings site and the abundance of the most common perennial species was estimated. Four of the five abundant perennial species showed evidence of regeneration: the ability to reproduce and establish new seedlings. A comparison of selected physicochemical properties of the tailings in vegetated patches with adjacent barren areas suggests that pH, electrical conductivity, texture, and concentration of potentially toxic elements do not limit plant distribution. For the most abundant species, the accumulation factor for most metals was <1, with the exception of Zn in two species. A short-term experiment on adaptation revealed limited evidence for the formation of local ecotypes inProsopis velutinaandAmaranthus watsonii. Overall, the results of this study indicate that five native plant species might have potential for phytostabilization of the Nacozari tailings and that seed could be collected locally to revegetate the site. More broadly, this study provides a methodology that can be used to identify native plants and evaluate their phytostabilization potential for similar mine tailings.
Role of interannual Kelvin wave propagations in the equatorial Atlantic on the Angola Benguela Current system

Published: May 2017

AbstractThe link between equatorial Atlantic Ocean variability and the coastal region of Angola‐Namibia is investigated at interannual time scales from 1998 to 2012. An index of equatorial Kelvin wave activity is defined based on Prediction and Research Moored Array in the Tropical Atlantic (PIRATA). Along the equator, results show a significant correlation between interannual PIRATA monthly dynamic height anomalies, altimetric monthly Sea Surface Height Anomalies (SSHA), and SSHA calculated with an Ocean Linear Model. This allows us to interpret PIRATA records in terms of equatorial Kelvin waves. Estimated phase speed of eastward propagations from PIRATA equatorial mooring remains in agreement with the linear theory, emphasizing the dominance of the second baroclinic mode. Systematic analysis of all strong interannual equatorial SSHA shows that they precede by 1–2 months extreme interannual Sea Surface Temperature Anomalies along the African coast, which confirms the hypothesis that major warm and cold events in the Angola‐Benguela current system are remotely forced by ocean atmosphere interactions in the equatorial Atlantic. Equatorial wave dynamics is at the origin of their developments. Wind anomalies in the Western Equatorial Atlantic force equatorial downwelling and upwelling Kelvin waves that propagate eastward along the equator and then poleward along the African coast triggering extreme warm and cold events, respectively. A proxy index based on linear ocean dynamics appears to be significantly more correlated with coastal variability than an index based on wind variability. Results show a seasonal phasing, with significantly higher correlations between our equatorial index and coastal SSTA in October–April season.

AbstractIn June 2013, a glider equipped with oxygen and fluorescence sensors has been used to extensively sample an anticyclonic Submesoscale Coherent Vortex (SCV) in the Ligurian Sea (NW Mediterranean Sea). Those measurements are complemented by full‐depth CTD casts (T, S, and oxygen) and water samples documenting nutrients and phytoplankton pigments within the SCV and outside. The SCV has a very homogeneous core of oxygenated waters between 300 and 1200 m formed 4.5 months earlier during the winter deep convection event. It has a strong dynamical signature with peak velocities at 700 m depth of 13.9 cm s−1 in cyclogeostrophic balance. The eddy has a small radius of 6.2 km corresponding to high Rossby number of −0.45. The vorticity at the eddy center reaches
. Cross‐stream isopycnic diffusion of tracers between the eddy core and the surroundings is found to be very limited due to dynamical barriers set by the SCV associated with a diffusivity coefficient of about 0.2 m2 s−1. The deep core is nutrients‐depleted with concentrations of nitrate, phosphate, and silicate, 13–18% lower than the rich surrounding waters. However, the nutriclines are shifted of about 20–50 m toward the surface thus increasing the nutrients availability for phytoplankton. Chlorophyll‐a concentrations at the deep chlorophyll maximum are subsequently about twice bigger as compared to outside. Pigments further reveal the predominance of nanophytoplankton inside the eddy and an enhancement of the primary productivity. This study demonstrates the important impact of postconvective SCVs on nutrients distribution and phytoplankton community, as well as on the subsequent primary production and carbon sequestration.
Absence of a detectable lunar nanodust exosphere during a search with LRO's LAMP UV imaging spectrograph

Published: May 2017

AbstractThe Lyman‐Alpha Mapping Project (LAMP) UV spectrograph on board the Lunar Reconnaissance Orbiter (LRO) performed a campaign to observe the Moon's nanodust exosphere, evidence for which was provided by the Lunar Atmosphere and Dust Environment Explorer (LADEE) Ultraviolet and Visible Spectrometer (UVS) during the 2014 Quadrantid meteoroid stream. These LADEE/UVS observations were consistent with a nanodust exosphere modulated by meteoroid impacts. LRO performed off‐nadir maneuvers around the peak of the 2016 Quadrantids, in order to reproduce, as closely as possible, the active meteoroid environment and observing geometry of LADEE/UVS. We analyzed LAMP spectra to search for sunlight backscattering from nanodust. No brightness enhancement attributable to dust, of any size, was observed. We determine an upper limit for dust column concentration of ~105 cm−2 for grains of radius ~25 nm, and an upper limit for dust column mass of ~10−11 g cm−2, nearly independent of grain size for radii <100 nm.

AbstractUsing the particle data measured by Van Allen Probe A from October 2012 to March 2016, we investigate in detail the radiation belt seed population and its association with the relativistic electron dynamics during 74 geomagnetic storms. The period of the storm recovery phase was limited to 72 h. The statistical study shows that geomagnetic storms and substorms play important roles in the radiation belt seed population (336 keV electrons) dynamics. Based on the flux changes of 1 MeV electrons before and after the storm peak, these storm events are divided into two groups of “large flux enhancement” and “small flux enhancement.” For large flux enhancement storm events, the correlation coefficients between the peak flux location of the seed population and those of relativistic electrons (592 keV, 1 MeV, 1.8 MeV, and 2.1 MeV) during the storm recovery phase decrease with electron kinetic energy, being 0.92, 0.68, 0.49, and 0.39, respectively. The correlation coefficients between the peak flux of the seed population and those of relativistic electrons are 0.92, 0.81, 0.75, and 0.73. For small flux enhancement storm events, the correlation coefficients between the peak flux location of the seed population and those of relativistic electrons are relatively smaller, while the peak flux of the seed population is well correlated with those of relativistic electrons (correlation coefficients >0.84). It is suggested that during geomagnetic storms there is a good correlation between the seed population and ≤1 MeV electrons and the seed population is important to the relativistic electron dynamics.
