Deconstruyendo el vilipendio de las masculinidades musulmanas en los Estados Unidos
Authors: Bosch Vilarrubias Marta 
Published: May 2019

Para entender las políticas internacionales del presidente Donald J. Trump, y en especial el veto migratorio puesto en marcha en junio de 2017, el presente artículo deconstruye la historia discursiva de vilipendio de las masculinidades árabes en los Estados Unidos. Empezando por los primeros encuentros coloniales, expuestos por Edward W. Said en Orientalismo, el artículo traza un recorrido histórico desde el siglo XVIII hasta la actualidad, haciendo especial hincapié en la patologización y adscripción de anormalidad al varón musulmán a través de su oximorónica caracterización como hipermasculino y emasculado. El articulo luego se centra en las consecuencias del 11 de septiembre de 2001, tomando como ejes de la reflexión los conceptos de abyección (Kristeva), biopolítica y gubernamentalidad (Foucault), y necropolítica (Mbembe), para así explicar como las masculinidades musulmanas fueron vilificadas al ser concebidas como masculinidades queer-ificadas y fallidas (Puar), contrapuestas a la masculinidad hegemónica occidental, y como Donald Trump ha re-apropiado estos discursos para intentar aseverar su propia hombría.
La Gran Guerra llega a España: la revista “Los Aliados” y la causa aliadófila
Authors: Tomasoni Matteo 
Published: May 2019

En este artículo se pretende analizar algunos de los acontecimientos finales de la Primera Guerra Mundial y los efectos que estos provocaron en un país neutral como España a lo largo de la segunda mitad de 1918. Este estudio se hará a través del enfoque periodístico de una revista aliadófila, Los Aliados, que en su momento se creó no solo como respuesta a los ambientes germanófilos –en su mayoría reunidos en torno a la revista Renovación Española–, sino también como núcleo intelectual comprometido con una paz democrática de claros matices wilsonianos. Lo que nos demostrará que, pese a su neutralidad, España permaneció muy atenta al desarrollo del conflicto y comprometida con un debate que con el tiempo proporcionó las condiciones de su futura adhesión a la Sociedad de Naciones. A este respecto, observaremos que la propaganda jugó un papel fundamental en este avance político, debido a la publicación –precisamente en Los Aliados– de una ingente cantidad de material propagandístico proveniente en su mayoría desde el exterior, originando a su vez la base y el filtro informativo más cercano a las posturas aliadófilas.
Una nación descamisada. Ortega y Gasset y su idea de España durante la Primera Guerra Mundial (1914-1918)
Authors: Archilés Cardona Ferran 
Published: May 2019

Ortega dedicó una atención algo escasa a la Primera Guerra Mundial en sus escritos. Pero para él la guerra fue una posibilidad de pensar la posibilidad de regeneración de la nación española . Estuvo menos interesado en escoger campos entre los aliados o Alemania que en lamentar los efectos de la neutralidad para España (en 1914 como en 1918). Esta equidistancia revisable fue, además, su manera de crearse un lugar en el campo de fuerzas intelectual y en la esfera política.Ortega insistió siempre en que la neutralidad, si era fruto de la debilidad, era la peor cosa que podía sucederle a España, pues la condenaba a la periferia de la toma de decisiones internacionales. Era causa y a la vez efecto de un mal más profundo, de una falta de vitalidad de la nación.El pensamiento de Ortega fue siempre, en su dimensión política, un pensamiento sobre la nación. Para Ortega, España seguía siendo una nación moribunda, por ello era precisa una fuerte tarea de regeneración nacional.
Da identidade religiosa: a singularidade judaica em Belo Horizonte em tempos de migração
Authors: Calvo Júlia , Ferreira Amauri Carlos 
Published: May 2019

O artigo discute e analisa a identidade religiosa judaica a partir do marco da diáspora que originou comunidades novas, marcadas por diferenças linguísticas, religiosas, históricas e culturais. A identidade judaica e sua configuração no campo religioso constitui na trama do simbólico o que é ser judeu em qualquer lugar do mundo, conduzindo a ideia de um povo /nação. Para entender o processo identitário do povo judeu foi necessário um contexto republicano. A capital mineira em sua fundação experimentou uma diversidade de povos migrantes judeus de diversas partes do país. Na formação da comunidade prevaleceram os judeus migrantes do Leste europeu responsáveis pelas primeiras organizações religiosas e comunitárias na cidade. A partir da década de 1930, principalmente com o aumento do antissemitismo europeu, a cidade passou a receber um outro grupo que trouxe novas contribuições para os judeus belo-horizontinos, ampliando a influência cultural e política, evidenciando uma singularidade no modo de ser judeu. O caminho escolhido para entender esse processo identitário e de singularidade foi o histórico.

Published: May 2019

Com o objetivo de investigar o comportamento termodinâmico da camada limite convectiva (CLC) na transição da estação seca para a chuvosa 2002/2003 no Oeste da Amazônia (Rondônia), foram comparados resultados observacionais obtidos em dois tipos de cobertura vegetal: floresta nativa e pastagem plantada. Os dados foram obtidos durante a campanha de 2002 do LBA (DRY TO WET) no período de 16 de setembro a 31 de outubro. Os resultados mostraram que o padrão de evolução da CLC, tanto na floreta, quanto na pastagem, foi bastante parecido com aqueles observados na estação chuvosa (LBA 1999). Em termos de desenvolvimento vertical, tanto os padrões de crescimento como os valores de espessura alcançados nos dois sítios foram praticamente iguais. A média na floresta foi de 858m e na pastagem de 888m. Os padrões de evolução dos valores médios e das taxas de variação temporal nos dois sítios, no interior da CLC, são, na sua maioria, semelhantes.

Osteoarthritis is characterized by articular cartilage breakdown, and emerging evidence suggests that dysregulated innate immunity is likely involved. Here, we performed proteomic, transcriptomic, and electron microscopic analyses to demonstrate that mast cells are aberrantly activated in human and murine osteoarthritic joint tissues. Using genetic models of mast cell deficiency, we demonstrate that lack of mast cells attenuates osteoarthritis in mice. Using genetic and pharmacologic approaches, we show that the IgE/FcεRI/Syk signaling axis is critical for the development of osteoarthritis. We find that mast cell-derived tryptase induces inflammation, chondrocyte apoptosis, and cartilage breakdown. Our findings demonstrate a central role for IgE-dependent mast cell activation in the pathogenesis of osteoarthritis, suggesting that targeting mast cells could provide therapeutic benefit in human osteoarthritis.Editorial note: This article has been through an editorial process in which the authors decide how to respond to the issues raised during peer review. The Reviewing Editor's assessment is that all the issues have been addressed (<xref ref-type="decision-letter" rid="SA1">see decision letter</xref>).

Published: May 2019

Studying Agriculture Knowledge Information System (AKIS) in terms of generation, dissemination, transformation, utilization, storage and retrieval of knowledge and information is needed for agriculture development. A study was conducted in Nadia district of West Bengal and Betel vine growers, Extensionist, Researchers were considered as respondents. Cultivation of betel vine is one of the most important horticultural crops at it is gradually increasing its popularity in the Nadia district as cash crop. It is observed that in- adequate information regarding Betel vine production in the sampled areas, almost cent percent growers were using their own traditional planting materials since long and growing their crops with their indigenous knowledge, skill and their past experiences. They have little awareness regarding the improved method of cultivation. The study further indicated that the respondents were receiving better information and technical knowhow about betel vine cultivation from Opinion leader, participating in training programmes, discussing with Extension personnels, input dealers, neighbours and different NGOs and to some extent from electronic media. The respondents treated relatives, neighbours and co-operatives as better credible sources followed by demonstration, campaign, Argil. University expert, Krishi-mela, Leaflet and Input dealers and electronic media to some extent. Establishment of research station, transfer knowledge information system and marketing system might be useful for realising better return on betel vine cultivation and young farmers are quite enthusiastic to cultivate the betel vine and promotion of this crop should be continued in the other parts of the district for gainful employment through need based and location specific technology support system.

Aims: To establish the most suitable extraction method for sweet lupine seeds and to determine minerals, phenolic content, flavonoids, antioxidant activity and antimicrobial activities.
Study Design: Known and standard experimental procedures are employed.
Place and Duration of Study: Department of Chemistry, Bethlehem University- Palestine, from January 2019 to March 2019.
Methodology: Seeds were ground and extracted by Soxhlet extractor using ethanol with different percentages (50%, 60%, 70%, 80% and 95%). Sodium, potassium and ferrous ion content were determined. Resistance to bacteria was performed against Escherichia coli and Staphylococcus aureus, while antioxidant activity was determined by FRAP method. Two types of flavonoids were measured: Flavonones and dihydroflavonols via the reaction with 2,4-dinitrophenylhydrazine. Phenolics were determined by the Folin-Ciocalteu method.
Results: 50% ethanol resulted in the highest extract residue (18.6%) while 70% and 60% showed the lowest content (10.0% for both). 80% ethanol extracted sample showed the highest content for sodium (56.51 mg Na/g extract), while 60% and 50% ethanol extracts showed the highest content of potassium (2.25 and 2.33 mg K/g extract, respectively). The maximum concentration of ferrous ion was obtained with 70% ethanol (6.854 mg Fe+2/g extract). 95% ethanolic extract showed the highest antioxidant activity (20.24 mg FeSO4/g extract). Similar results were obtained for total phenolic content and flavonoids: 24.60 mg gallic acid/g extract for phenolics and 116.02 mg rutin/g extract for flavonoids. Extracts showed no bacterial activity against both types of bacteria used.
Conclusion: 95% ethanol extracted samples showed the highest antioxidant activity and the highest flavonoids and phenolic content. Sweet lupine extract did not perform any antimicrobial activity against both Gram positive and Gram negative bacteria.

Published: May 2019

Aims: To determine the safety of caloric substitution with 10% (g/kg) apple pomace to a healthy or Western diet.
Study Design: Growing (age 22-29 days) female Sprague-Dawley rats were randomly assigned (n=8 rats/group) to consume a purified standard rodent diet (AIN-93G), AIN-93G/10% g/kg apple pomace (AIN/AP), Western diet, or Western/10% g/kg apple pomace (Western/AP) diets for 8 weeks.
Results: Histological evaluation showed renal interstitial hypercellularity in rats fed AIN/AP, Western, and Western/AP diets. However, there were no effects on renal expression of oxidative stress and inflammatory genes or serum measures of kidney damage and function among diet groups. Apple pomace was also high in calcium which can affect calcium balance. Dietary calcium consumption was highest (P < .001) in rats consuming Western/AP. However, there were no significant differences in calcium absorption and retention among diet groups. Further, there was no evidence of renal calcification. There were also no impacts on femoral calcium, total mineral content, size or strength.
Conclusions: Based on the results, apple pomace consumption was safe for renal and bone health in a rodent model, regardless of diet quality. Future preclinical studies should be conducted to further determine the efficacy and safety of apple pomace.

Aim: Comparative Effects of Some Preservative Hurdles on the Quality of Zobo Stored at Ambient Temperature were assessed.
Place and Duration of Study: Department of Microbiology Federal University of Technology, Minna, Nigeria, between June 218 and January 2019.
Methodology: Fresh zobo drink samples were prepared from Hibiscus sabdariffa using modified methods of HACCP and Hurdle technology for preservation and stored on the shelf for six months. The samples were divided into seven. Analyses were carried out on monthly basis with respect to microbial quality, pH, titratable acidity (TTA), total soluble solids (TSS), vitamin C content and sensory qualities of the beverage for six months. The parameters changed significantly (p<0.05) with respect to storage period. Zero microbial count was recorded for all the samples as at the time of production.
Results: The control sample deteriorated after one month, pasteurization at 75°C for 20 minutes successfully eradicated all coliforms and indicator organisms as none was isolated during the shelf study. Bacillus subtilis, Lactobacillus fermentum, Aspergillus niger, penicillium sp, Saccharomyces cerevisiae isolated from the both the control and pasteurized (Gcontrol and G2) samples were responsible for the spoilage of the beverage after one month. G3, G4 G5, G6 and G7 preserved beyond six months, without imparting negatively on the sensory qualities of the drink. They significantly (p<0.05) showed the same overall acceptability, mouthfeel, flavour, colour and taste.
Conclusion: Sample G3 stored best after six months on the shelf.

Published: May 2019

Human dihydroorotate dehydrogenase (DHODH), the enzyme that catalyzes the rate‐limiting step in de novo pyrimidine biosynthesis, is considered to be an attractive target for potential treatment of autoimmune disease and cancer. Here, we present a novel class of human DHODH inhibitors with high inhibitory potency. The high‐resolution crystal structures of human DHODH complexed with various agents reveal the details of their interactions. Comparisons with the binding modes of teriflunomide and brequinar provide insights that may facilitate the development of new inhibitors targeting human DHODH.
Temporal Control of Plant–Environment Interactions by the Circadian Clock
Authors: Haydon Michael J. , Li Xiang , Ting Michael K.Y. 
Published: May 2019

AbstractThe rotation of the earth generates dramatic daily and seasonal variation in the terrestrial environment. Plants, like other organisms, have evolved an endogenous biological oscillator to predict these daily changes in light and temperature and adjust to shifting seasonal conditions. This system must be robust to unexpected environmental challenges but can also assist plants to adjust physiology accordingly. Key features of the circadian system that contribute to achieve these are the process of entrainment, by which external cues adjust the state of the oscillator, and gating, by which the sensitivity to a stimulus is modified according to the time of day. In this way, the circadian clock is a dynamic hub which integrates physiology, metabolism, and growth in the context of a plant's current environment. We provide a comprehensive summary of the molecular composition of the core oscillator in Arabidopsis and the mechanisms of entrainment and gating. In particular, we focus on phytohormone signalling, photosynthetic metabolism, and defence responses as examples of core plant responses to environment that are integrated within the circadian system.
Thermally Conductive Reduced Graphene Oxide Thin Films for Extreme Temperature Sensors

Published: May 2019

AbstractReduced graphene oxide (RGO) films are promising in applications ranging from electronics to flexible sensors. Though high electrical and thermal conductivities have been reported for RGO films, existing thermal conductivity data for RGO films show large variations from 30 to 2600 W m−1 K−1. Further, there is a lack of data at low temperatures (<300 K), which is critical for the understanding of thermal transport mechanisms. In this work, a temperature‐dependent study of thermal (10–300 K) and electrical (10–3000 K) transport in annealed RGO films indicates the potential application of RGO films for sensing temperatures across an extremely wide range. The room‐temperature thermal conductivity increases significantly from 46.1 to 118.7 W m−1 K−1 with increasing annealing temperature from 1000 to 3000 K with a corresponding increase in the electrical conductivity from 5.2 to 1481.0 S cm−1. In addition, films reduced at 3000 K are promising for sensing extreme temperatures as demonstrated through the measured electrical resistivity from 10 to 3000 K. Sensors based on RGO films are advantageous over conventional temperature sensors due to the wide temperature range and flexibility. Thus, this material is useful in many applications including flexible electronics and thermal management systems.

Published: May 2019

AbstractPaper‐based superomniphobic surfaces are of great interest because paper is flexible, inexpensive, lightweight, breathable, and recyclable. Prior reports on paper‐based superomniphobic surfaces have failed to demonstrate high mobility with low surface tension liquids. In order to overcome this issue, in this work, superomniphobic papers are developed through growth of nanofilaments on inherent microfibers of papers without noticeably altering their microscale features (i.e., diameter and distance of the microfibers). These superomniphobic papers display very low roll‐off angle, indicative of ultra‐high droplet mobility, even with low surface tension liquids. Here, a facile method is also developed to control the motion and adhesion of the droplets on the superomniphobic paper. Utilizing such liquid mobility in a controlled manner on these superomniphobic papers, a simple on‐paper pH sensor is fabricated. It is anticipated that this on‐paper, simple, and rapid detection methodology can also be extended to the colorimetric sensing of protein and chemical assays. Further, these superomniphobic papers have potential applications in water–oil separation and enhanced weight‐bearing capacity.

AbstractRecent studies on flexible/stretchable medical electronics are almost all focusing on passive monitoring of physiological signs for medical diagnostics, but rare reports have been found on those for active therapeutic purposes. Here, a novel infrared skin‐like active stretchable electronics (ISASE) is introduced with the organic–inorganic composite design for promotion of cutaneous wound healing, which can be conformally mounted anywhere on the human body due to its excellent flexibility and stretchability. Comprehensive experiments, including the proliferation and migration of human skin fibroblasts and rat dermal fibroblasts in vitro, and various tests on wound healing of rats, show favorable effects of the ISASE on promoting the fibroblast migration and proliferation, reducing the inflammatory phase, stimulating the angiogenesis, and shorting the wound healing period. A typical ISASE significantly shortens the cure time for a wounded rat by at least two days compared with the normal treatment with 12 days cure. The mechanical tests confirm the validity of the ISASE when used in extreme large deformations (e.g., stretched by up to 80% strain), which enables the conformability with the human body. The present portable and wearable ISASE demonstrates great potential for cutaneous wound healing, which constitutes an important complement to the current applications in the healthcare field.
Rh(III)‐Catalyzed Distal C‐H Alkenylation of Weakly Coordinating Acetamides Via Desilylation Pathway

Published: May 2019

AbstractRh(III)‐Catalyzed distal ortho‐C−H alkenylation of arylacetamides have been reported employing acetamide, a weak coordinating group, as a directing group. This challenging C−H alkenylation of arylacetamides has been achieved by using arylalkynyl silanes as a surrogate for terminal alkynes under redox neutral process through desilylation pathway. The control experiments suggest that the in situ generatedRh‐species is likely to be Lewis acidic, which is playing a vital role in the desilylation step.magnified image
Palladium‐Catalyzed Umpolung Type‐II Cyclization of Allylic Carbonate‐Aldehydes Leading to 3‐Methylenecycloalkanol Derivatives
Authors: Tsukamoto Hirokazu , Kawase Ayumu , Doi Takayuki 
Published: May 2019

AbstractPalladium‐catalyzed umpolung type‐II cyclization of allylic carbonate‐aldehydes leading to 3‐methylenecycloalkanol derivatives was developed. The formate reductant was effective for the cyclization without causing a reduction of the η3‐allylpalladium intermediate. One‐pot decarboxylative allylation of aldehyde‐containing malonate with 2‐[(acetyloxy)methyl]‐2‐propenyl methyl carbonate followed by the cyclization of the allyl acetate‐aldehyde formed in situ was also achieved. The high diastereoselectivities observed in the cyclization of branched substrates indicates that a chair‐chair transition state should be involved. Based on the presumed transition state, we could predict the enantioselectivity of the cyclization using SEGPHOS as a chiral diphosphine ligand and obtain optically active alcohols in up to 95:5 er.magnified image
