Introducción: Los manglares son los mayores sumideros de carbono y contribuyen a mitigar los efectos del cambio climático global.Objetivo: Estimar la biomasa aérea (BA) del estero El Sargento y de la Bahía del Tóbari, para comparar los almacenes de carbono entre ambos lugares.Materiales y métodos: Las mediciones se realizaron en mayo de 2014 a noviembre de 2015. Las especies se identificaron, y el diámetro de árboles, altura y cobertura del dosel se midieron en 16 parcelas de 10 x 10 m. La BA se estimó con ecuaciones alométricas y se relacionó con el contenido de carbono mediante el factor 0.5. Las diferencias estadísticamente significativas entre los contenidos de carbono de ambos sitios de estudio se detectaron con la prueba t para muestras independientes.Resultados y discusión: La BA en el estero El Sargento se estimó entre 108.1 y 316.78 Mg∙ha-1 con predominancia de Laguncularia racemosa (L.) Gaertn (60 %); en Bahía del Tóbari, la BA varió entre 72.12 y 130 Mg∙ha-1, prevaleciendo Avicennia germinans (L.) L (83.4 %). En los dos sitios se encontró Rhizophora mangle L. de manera marginal. El almacén total de carbono fue mayor en El Sargento (con un rango de 54.1 a 158.4 Mg C∙ha-1) que en Bahía del Tóbari (36.1 a 65.5 Mg C∙ha-1); la diferencia fue estadísticamente significativa (F = 0.01; P = 0.02).Conclusión: La diferencia en las reservas de carbono de los lugares de estudio se relaciona con el buen desarrollo y diversidad de especies de un medio ambiente prístino (El Sargento), en comparación con otro severamente impactado (Bahía del Tóbari).

This research aimed to find out how lighting influence visual task performance of the elderly.The experiment was done on the table with different lamp position and by giving mark on the landolt ring chart printed on different reading media. Three position, the front, the middle and the back were the variables for lamp position, whilst different reading medias were the brown paper usually used for newspaper, the white silk uncoated paper or ‘HVS’ paper and the white gloss paper. The lamp were TL5 LED with 4000 °K and 6500 °K color temperature. The illumination level maintained specificly at 250-325 lux range. The respondents were 12 elderly with 58 years as the mean age. The result findings, for newspaper, the best position for speed was the front with 1.15 second per stroke; followed by the back with 1.18 second per stroke; and the middle got the lowest result with 1.4 second per stroke. For the HVS and glossy paper with higher luminance, the best for speed was the middle position that was the darkest in illumination, with 1.25 second per stroke for HVS and 1.3 second per stroke for glossy. The worst result was the back with 1.4 second per stroke for HVS and 1.36 second per stroke for glossy paper. For accuracy, the best for newspaper was the front, 96.02%. For the HVS paper, the middle and the back position has got the same highest accuracy, 90.45%. For the glossy paper, the middle position has got the highest accuracy, 91.62%. The visual task performance result, for the newspaper, the front position has got the highest score, followed by the back position that have brighter in illumination, but the score was lowest for the middle position. Contrary, for white HVS and white gloss paper, which get almost identic result, the middle position which was rather dark in illumination was the best, while the front and the back position were worse in visual task performance score. So that can be concluded that the higher illumination level was not always give the best to visual task performance; but depending to the user and the kind of paper or reading media as well.
COSMOGENIC ARCHITECTURE: A STUDY OF YOKA SARA’S DESIGN APPROACH ON ANTONIO BLANCO’S HOTEL
Authors: Widyaevan Dea Aulia 
Published: September 2018

The Antonio Blanco’s hotel design by Balinese base architect Yoka Sara been design to represent the extension of Antonio Blanco’s museum in Ubud Bali. Although this design only achieves in a preliminary stage, the design approach in which Yoka Sara offer to interpret the style of Balinese contemporary, reflect the idea of Cosmogenic Architecture by Charles Jencks. In his book “Architecture of The Jumping Universe” Jencks stated about how in the postmodern era, the architect should have the freedom to use architecture as a language. The nature of architecture has been identified with a definition of the universe through contemporary sciences. This paper tries to reveal the cosmogenic value in Antonio Blanco’s hotel approach by analogizing the architectural vocabulary into the linguistic system as Jencks mention in his book “The Language of Postmodern Architecture”. The issue of genius loci concept of cosmos also discusses to be coherent with the idea of cosmos in contemporary science. In related to architecture design, and a new way to re-define cosmos in contemporary Balinese architecture

Published: September 2018

AbstractHydrogen has attracted considerable attention as an energy source, and various attempts to develop suitable methods for hydrogen generation are made at the National Institute of Advanced Industrial Science and Technology. In this paper, the authors introduce their recent strategies to store hydrogen using formic acid (FA) as a hydrogen carrier. FA, which is believed to be one of the most promising liquid organic hydrogen carriers, can provide a viable method for safe hydrogen transportation. In order to optimize the performance of hydrogen storage with FA, the authors have investigated both homogeneous and heterogeneous catalysts. For example, Ir catalysts anchoring N^N‐bidentate ligands show high catalytic activity for both the reactions of FA synthesis and hydrogen generation from FA. Ultrafine Pd‐based nanoparticles are also immobilized on various supports, which show excellent catalytic performance for FA dehydrogenation under mild conditions. The authors also develop both homogeneous and heterogeneous catalysts to generate high‐pressure gases (H2 and CO2) over 120 and 35 MPa, respectively, from direct FA dehydrogenation without any compressing procedures. The generated high‐pressure gases (H2 and CO2) can be easily and simply separated by changing the fluid phase from the supercritical to gas–liquid phase by cooling without depressurization.

AbstractExploring effective electrocatalysts for oxygen evolution reaction (OER) is a crucial requirement of many energy storage and conversion systems, involving fuel cells, water splitting, and metal–air batteries. Herein, a heterogeneity metal‐organic framework (MOF) is prepared by the assembling of metals, terephthalic (A) and 2‐aminoterephthalic ligands (B), defined as A2.7B‐MOF‐FeCo1.6. More importantly, A2.7B‐MOF‐FeCo1.6 exhibits excellent OER activity with an ultralow overpotential of 288 mV at 10 mA cm−2 and a Tafel slope of 39 mV dec−1. The high electrocatalytic performance for OER is attributed to the optimized electronic structure of the intrinsic catalytic center in MOFs via the engineering of the metal node and linkers. The work offers not only a benchmark for pure MOFs in electrocatalysis but also a new efficient strategy to improve electrocatalytic performance by electronic structure engineering of catalytic active centers in MOFs.

BackgroundQuality improvement (QI) in the management of chronic rhinosinusitis (CRS) is garnering increasing attention. Defining frameworks and metrics to assess the quality of key components in CRS management could assist in reducing unwarranted practice variation and increase high‐quality care.MethodsA panel of the American Rhinologic Society (ARS) QI committee reviewed the literature to determine important presurgical components of CRS care that warrant QI. The evidence was organized into 4 categories: (1) diagnosis, (2) medical management, (3) appropriate patient selection for surgery, and (4) patient‐centered discussion. The combination of these categories was used to develop a framework termed the CRS Appropriate Presurgical Algorithm (CAPA).ResultsPrior to offering surgery for CRS, the best available evidence support the following quality metrics: (1) a guideline‐based diagnosis should be confirmed; (2) appropriate medical management, including a minimum of topical corticosteroid therapy and saline irrigations, should have been attempted (assuming patient tolerance); (3) a computed tomography (CT) scan should be obtained (to confirm the presence of sinus inflammation and for surgical planning); and (4) a patient‐centered discussion regarding treatment options for refractory CRS (ie, alternative medical therapies vs surgery vs observation) while focusing on risks and benefits, the need for long‐term medical compliance, and understanding of patient preferences and expectations.ConclusionDefining metrics that assess key components to CRS care prior to offering surgery has the potential to further improve upon an already successful treatment paradigm, reduce unwarranted practice variation, and to ensure that patients are receiving a similar level of high‐quality care.

ABSTRACTThe performance and modification mechanism of Buton rock asphalt (BRA) modified asphalt were analyzed. The road performance of modified asphalt was observed and compared with SBS modified asphalt to confirm the modification mechanism. Four‐component test, and dynamic shear rheological tests were conducted to identify the performance of modified asphalt. Fourier transform infrared spectroscopy was carried out to analyze the modification mechanism of modified asphalt. Finally, the rutting, low‐temperature bending beam failure, and freeze–thaw splitting tests were used to evaluate the high‐temperature performance, low‐temperature cracking resistance, and water stability performance of mixtures, respectively. The results show that the high‐temperature performance of asphalt can be improved by BRA with asphaltene and resin increased. It is likely that there is no new functional group generated and this process was physical changes mainly. The honeycomb structure of BRA ashes/particles increased the contact area between the base asphalt and BRA ashes/particles, which makes the asphalt change from the homogeneous body into a two‐phase continuous structure system. Consequently, the adhesion between asphalt and BRA ashes/particles was enhanced, and the dynamic stability, bending coefficient and splitting strength ratio were improved. It indicates that the test results of asphalt mixtures verified the modification effect of BRA. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 46903.

Published: September 2018

AbstractThis paper reports the preparation of new ruthenium(II) complexes supported by a pyrazole‐phosphine ligand and their application to transfer hydrogenation of various substrates. These Ru complexes were found to be efficient catalysts for the reduction of nitriles and olefins. Heterocyclic compounds undergo transfer hydrogenation with good to moderate yields, affording examples of unusual hydrogenation of all‐carbon‐rings. Internal alkynes with bulky substituents show selective reduction to olefins with the unusual E–selectivity. Esters with strong electron‐withdrawing groups can be reduced to the corresponding alcohols, if ethanol is used as the solvent. Possible mechanisms of hydrogenation and olefin isomerization are suggested on the basis of kinetic studies and labelling experiments.

AbstractSingle‐atom catalysts with ionic Pd active sites supported on nitrogen‐doped carbon nanotubes have been synthesized with a palladium content of 0.2–0.5 wt %. The Pd sites exhibited unexpectedly high stability up to 500 °C in a hydrogen atmosphere which was explained by coordination of the Pd ions by nitrogen‐containing fragments of graphene layers. The active sites showed a high rate of gas‐phase formic acid decomposition yielding hydrogen. An increase in Pd content was accompanied by the formation of metallic nanoparticles with a size of 1.2–1.4 nm and by a decrease in the catalytic activity. The high stability of the single‐atom Pd sites opens possibilities for using such catalysts in high‐temperature reactions.

AbstractObjectiveLittle epidemiological evidence exists on rumination disorder behavior (RB) and pica behavior (PB). We examined prevalence of RB and PB and presence of comorbid feeding/eating disorder symptoms among school‐aged children.MethodIn elementary schools in Switzerland, 1,430 children (54.0% female) ages 7–13 completed the Eating Disorder Examination‐Questionnaire for children (ChEDE‐Q) and the Eating Disturbances in Youth Questionnaire (EDY‐Q).ResultsEDY‐Q behavior frequency showed 9.7% reported RB only, 10.0% reported PB only, and 3.1% reported RB + PB (≥1 on 0–6 Likert scale). At a clinical cut‐off score of ≥ 4, 1.7% had RB only, 3.8% had PB only, and 1.1% had RB + PB. Avoidant/restrictive food intake disorder symptoms were most common in those with RB + PB, and more common in those with RB or PB than those without. The degree of eating disorder symptoms (by ChEDE‐Q) over the past 28 days were similar among those with RB, PB, or RB + PB, but less common in those without RB or PB.DiscussionRB and PB were commonly reported in our sample of school‐aged children, even at a potential clinically significant cut‐off. Our findings also suggest that the degree of eating disorder symptom comorbidity is similar between those with RB and PB.

Published: September 2018

AbstractDistinct functional cell types in the medial entorhinal cortex (mEC) have been shown to represent different aspects of experiences. To further characterize mEC cell populations, we examined whether spatial representations of neurons in mEC superficial layers depended on the scale of the environment and changed over extended time periods. Accordingly, mEC cells were recorded while rats repeatedly foraged in a small or a large environment in sessions that were separated by time intervals from minutes to hours. Comparing between large and small environments, we found that the overall precision of grid and non‐grid cell spatial maps was higher in smaller environments. When examining the stability of spatial firing patterns over time, differences and similarities were observed across cell types. Within‐session stability was higher for grid cells than for non‐grid cell populations. Despite differences in baseline stability between cell types, stability levels remained consistent over time between sessions, up to 1 hr. Even for sessions separated by 6 hrs, activity patterns of grid cells and of most non‐grid cells lacked any systematic decrease in spatial similarity over time. However, a subset of ~15% of mEC non‐grid cells recorded preferentially from layer III exhibited dramatic, time dependent changes in firing patterns across 6 hrs, reminiscent of previous characterizations of the hippocampal CA2 subregion. Collectively, our data suggest that mEC grid cell input to hippocampus in conjunction with many time invariant non‐grid cells may aid in stabilizing hippocampal spatial maps, while a subset of time varying non‐grid cells could provide complementary temporal information.
MIL‐53 and its Isoreticular Analogues: a Review of the Chemistry and Structure of a Prototypical Flexible Metal‐Organic Framework
Authors: Millange Franck , Walton Richard I. 
Published: September 2018

AbstractWe present a review of the structural chemistry of metal‐organic framework materials with the MIL‐53 type structure. This family of materials is well‐known for its structural flexibility, and also the wide variety of metal cations and functional ligands that can be included. This gives rise to a set of multivariate materials and isoreticular analogues, to which isoreticular functionalisation can also be applied. Starting from the parent structure, containing infinite chains of octahedral trivalent metal cations cross‐linked by benzene‐1,4‐dicarboxylate, we illustrate the compositional variety possible: this includes materials that contain tetravalent and divalent cations, mixtures of metal cations, functionalised ligands, expanded structures from extended linkers and inclusion of pendant ligands. We emphasise the crystal chemistry of this group of materials, but will give some examples of properties, particularly those associated with the structural breathing effect of relevance to molecular sieving, and also discuss emerging practical applications.

AbstractBACKGROUNDThe c‐type cytochrome of the CymA of Shewanella oneidensis MR‐1 is essential for the anaerobic respiration of Shewanella sp. and transfers electrons from the inner membrane to various terminal electron acceptors, such as soluble redox shuttles and insoluble metal oxides. CymA is believed to be a passage to the outer membrane for dissipating the respiratory electron to the carbon electrode in a microbial fuel cell (MFC) with simultaneous electricity generation. While the deletion and heterologous expression of cymA in Escherichia coli have been studied, there are no reports of the overexpression and its effects on the corresponding bioelectrochemical performance in a MFC.RESULTSThe cymA gene was overexpressed in Shewanella oneidensis MR‐1, and its upregulation was examined under aerobic, anaerobic, and MFC operating conditions by a reverse transcription‐polymerase chain reaction (RT‐PCR). Overexpression of the CymA protein was confirmed by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS‐PAGE). The MFCs inoculated with the engineered strains of MR‐1 achieved a higher maximum power of 0.13 mW and specific growth rate of 0.087 h−1 than those of the wild type MR‐1 (0.11 mW and 0.043 h−1, respectively). The higher electrochemical activity of the mutant strains demonstrated by cyclic voltammetry and linear sweep voltammetry, indicates that more respiratory electrons can be transferred to the electrodes through overexpression of the cymA gene of MR‐1 in a MFC.CONCLUSIONOverexpression of CymA improves the bioelectrochemical performance of MFCs. This suggests that metabolic engineering of a membrane‐associated redox protein, such as CymA, can further improve electricity generation of MFCs and produce an electrochemically enhanced bioprocess. © 2018 Society of Chemical Industry

AbstractBackgroundThis initiative aims to build a global consensus around core diagnostic criteria for malnutrition in adults in clinical settings.MethodsThe Global Leadership Initiative on Malnutrition (GLIM) was convened by several of the major global clinical nutrition societies. Empirical consensus was reached through a series of face‐to‐face meetings, telephone conferences, and e‐mail communications.ResultsA 2‐step approach for the malnutrition diagnosis was selected, that is, first screening to identify at risk status by the use of any validated screening tool, and second, assessment for diagnosis and grading the severity of malnutrition. The malnutrition criteria for consideration were retrieved from existing approaches for screening and assessment. Potential criteria were subjected to a ballot among GLIM participants that selected 3 phenotypic criteria (non‐volitional weight loss, low body mass index, and reduced muscle mass) and 2 etiologic criteria (reduced food intake or assimilation, and inflammation or disease burden). To diagnose malnutrition at least 1 phenotypic criterion and 1 etiologic criterion should be present. Phenotypic metrics for grading severity are proposed. It is recommended that the etiologic criteria be used to guide intervention and anticipated outcomes. The recommended approach supports classification of malnutrition into four etiology‐related diagnosis categories.ConclusionsA consensus scheme for diagnosing malnutrition in adults in clinical settings on a global scale is proposed. Next steps are to secure endorsements from leading nutrition professional societies, to identify overlaps with syndromes like cachexia and sarcopenia, and to promote dissemination, validation studies, and feedback. The construct should be re‐considered every 3–5 years.
