Published: January 2017

Abstract
The determination of polyphenols in wines is of great interest in the field of food analysis due to health and organoleptic implications. In addition, the applicability of polyphenols as food descriptors to be used for characterization, classification, and authentication purposes is gaining popularity. In this work, a simple and reliable method based on HPLC separation in reversed-phase mode with UV-Vis detection was developed and applied to determine polyphenolic compounds in white wines. The chromatographic separation was performed using aC18 column under a methanol elution gradient and assessed by an experimental design approach. Analytical parameters were established under the optimal experimental conditions. LOD values were between 3 and 220 µg/L, and repeatability values were better than 1% for most of the analyzed polyphenols. Compositional data were further exploited to characterize white wines based on principal component analysis to discriminate among mono- and polyvarietal compositions.

Published: January 2017

O presente estudo tem como objetivo estabelecer uma discussão acerca dos mapas presentes em dois livros didáticos utilizados no primeiro e segundo ano do ensino médio de geografia no Estado de Minas Gerais. Três critérios foram adotados na análise dos mapas. Inicialmente foi feito uma análise exploratória dos documentos cartográficos existentes, onde foi adotada a metodologia de Bertin (1977) e Martinelli (2003) para a classificação dos mapas. Em seguida, os mapas selecionados foram analisados levando em consideração os elementos da comunicação visual e proposições, quando necessárias, foram sugeridas com o intuído de melhorar a percepção das informações contidas nos mapas. Finalmente, foi analisada a conexão do conteúdo teórico com as informações dos mapas apresentados. Esta etapa foi importante porque permitiu avaliar a real funcionalidade do mapa no ensino de geografia contido nos dois livros selecionados. Os resultados mostraram que no geral, os mapas são bem apresentados e que há um forte desequilíbrio de métodos cartográficos empregados. Infelizmente, também foi observada uma fraca conexão do conteúdo teórico com os mapas apresentados, sendo estes mais utilizados como instrumento de localização do que de comunicação visual.

Published: January 2017

Fungal infections are the main cause of emerging infectious diseases in forest trees. Over the past decades, the number of invasive fungal pathogens in Europe has increased exponentially. In this paper the fungal pathogens causing the most common diseases in pines like Dothistroma needle blight, brown spot needle blight, Lophodermium needle cast, Scots pine blister rust, Scleroderris canker, and Pitch canker were analyzed. These diseases cause defoliation, increase susceptibility of plants to other diseases and pests, and tree mortality can also occur. As a result, the forest industry is suffering severe economic losses. The fungi species causing infection in forest trees have been described as serious pathogens across the world including Europe, confirming a fast spread of their ranges. Knowledge of pathogens distribution, life cycle and disease symptoms are essential for the diagnostic and control of pathogenic fungi. Human-driven species expansion has increased in the last century due to the growth of international travel and trade, resulting in huge disturbance to ecosystems. Most of the plant diseases are strongly influenced by environmental conditions. Climate change has important consequences on plants, pathogens, and the interaction between them, resulting in changes on diseases epidemics. Fungal infections of plants are difficult to control because pathogens populations are variable in time, space, and genotypes. The potential damage in the future may be large, and that is why we have to be aware of the problems and discuss some possible approaches to reducing the threats.

La diáspora obligada a partir del ‘arreo’: aproximaciones a poemas de Juan Pablo Riveros y Christian Formoso / Round-up forced diaspora in poems by Juan Pablo Riveros y Christian Formoso
Authors: Mellado Silvia Renee 
Published: January 2017

En una serie de trabajos, he abordado la representación de los traslados forzosos del pueblo mapuche y tehuelche (1870 - 1900), a partir de la imagen del ‘arreo’, en textos actuales del ‘área cultural sur’ (Espinosa 2014). El presente trabajo intenta continuar las indagaciones sobre las relaciones entre sujeto, cuerpo y mercancía vinculadas con la ganadería a partir de un corpus de poemas pertenecientes a Juan Pablo Riveros y Christian Formoso. En especial, las relaciones que se establecen entre el exterminio de los pueblos australes durante el proceso de colonización del siglo XIX y las detenciones en el marco de la dictadura cívico militar de chile (1973 -1990). Palabras clave: poesía, arreo, Patagonia austral, Riveros, Formoso. In a group of works in “Área Cultural Sur” (Espinosa, 2014), I have dealt with the representation of the forced moves of the Mapuche and Tehuelche people ((1870 – 1900) based on the image of “The roundup” (arreo). The present work aims to continue the enquiry about the relationship between subject, body and goods in connection to stockbreeding by exploring a corpus of poems by Juan Pablo Riveros and Christian Formoso. I particularly aim to explore the relation between the extermination of the southern people during the process of colonization in the XIX century and the detentions during the civic- military dictatorship in Chile (1973-1990).

El testimonio recurrente de la experiencia concentracionaria de Jorge Semprún: dar voz al silencio y a la palabra
Authors: Coca Méndez Beatriz 
Published: January 2017

La prosa sempruniana se caracteriza por la circularidad y la reiteración de ciertos episodios vividos, que ilustran pasajes de su narrativa –autobiográfica y de ficción. La iteración, más que recurso estilístico, parece dar consistencia a una inquietud de primer orden: dar consistencia al recuerdo de una experiencia límite y, por ello, perseguir sin descanso su vitalidad para que sea contraofensiva al olvido. El paso por Buchenwald es una vivencia capital para el escritor-testigo, ya que lo inefable de dicha experiencia requiere una organización estética que dé cartas de naturaleza a la sustancia que la nutre. La estructura reticular se torna una sutil tela de araña que enlaza los diferentes episodios, con la esperanza de dar voz a los acallados y a los que sobrevivieron. Palabras clave: prosa concentracionaria; Buchenwald; memoria; autobiografía; Jorge Semprún.
Los olores de Buchenwald. Memoria olfativa de Jorge Semprún en La escritura o la vida
Authors: García Cames David 
Published: January 2017

La literatura de los supervivientes de los campos se expresa como una tensión entre la exigencia ética del testimonio y la búsqueda de la palabra precisa que sepa dar cuenta de él. Este trabajo aborda uno de los clásicos de la literatura concentracionaria, La escritura o la vida (1994) de Jorge Semprún, a partir del análisis de los mecanismos descriptivos mediante los cuales el autor se acerca a los olores que era posible percibir en Buchenwald. La memoria olfativa se constituye como una forma de construcción de la otredad cuya pregnancia queda fijada en la escritura. La persistencia de ese recuerdo sensorial simboliza para Semprún la vivencia directa de la muerte y la condición inefable de su paso por el Lager. Palabras clave: Jorge Semprún; literatura concentracionaria; memoria olfativa; inefabilidad; otredad.
'Maus' y 'El arte de volar': dos representaciones paradigmáticas del universo concentracionario
Authors: García Navarro Carmen 
Published: January 2017

La conjunción de lo visual y lo textual ofrece en el cómic una particular visión de la representación ficcional del referente histórico. Si bien los autores que nos ocupan (Spiegelman; Altarriba) no son testigos directos, la transmisión intergeneracional de lo vivido permite articular y reflexionar en sus narraciones sobre lo traumático, lo criminal y lo inhumano de estos campos de exterminio o internamiento que fueron tanto Auschwitz como, en el caso francés, Saint-Cyprien. El ejercicio metanarrativo de Maus o la apropiación de la voz testimonial del narrador de Altarriba son algunos de los recursos narrativos y gráficos sometidos aquí a análisis como estrategias para solventar la problemática representación de lo real, la experiencia traumática y la imagen de los campos de concentración. Palabras clave: cómic; campos de concentración; memoria; testimonio; compromiso.
La memoria catalana de los campos de concentración franceses. Apuntes para una síntesis
Authors: García Raffi Josep Vicent 
Published: January 2017

La diáspora republicana producida por el final de la Guerra Civil española significó el exilio de decenas de miles de personas. Muchas de ellas pasaron por los Pirineos y fueron internadas en grandes campos de concentración improvisados en playas y toda clase de lugares, sobre todo del Rosellón. Esta experiencia límite generó una gran variedad de textos de literatura memorialista de los exiliados republicanos. Una parte importante la realizaron refugiados catalanes, alguno de ellos escritores, otros ciudadanos anónimos que querían consignar lo que habían vivido con la derrota. Se trata de una literatura memorialística, autobiográfica o ficcional que ofrece una textualidad diversa. Palabras clave: campos de concentración franceses; escritura concentracionaria; literatura catalana; literatura autobiográfica; diàspora republicana.

Liana Millu e Charlotte Delbo: scrivere e riscrivere la memoria
Authors: Sanfilippo Marina 
Published: January 2017

Questo lavoro propone un’analisi delle strategie di costruzione della memoria del lager usate da autrici che vissero la deportazione nazista e a tal scopo studia le opere di Millu e Delbo, due delle voci femminili più personali della letteratura della Shoah caratterizzate da una poetica frammentaria, in cui la riscrittura ossessiva di alcuni episodi occupa un luogo cruciale. Considero opportuno stabilire tra le due autrici un parallelismo che, superando i confini delle letterature nazionali, serva ad evidenziare possibili coincidenze tematiche e strutturali e a verificare la solidità di ipotesi generali su caratteristiche specifiche della scrittura a mano femminile nella letteratura concentrazionaria. Parole chiave: Charlotte Delbo; Liana Millu; memoria; letteratura della Shoah; prospettiva di genere.
Forward Head Posture and Activation of Rectus Capitis Posterior Muscles
Authors: Hallgren Richard C. , Pierce Steven J. , Sharma Dhruv B. , Rowan Jacob J. 
Published: January 2017

Abstract

Context: Rectus capitis posterior (RCP) muscles have physical attachments to the pain-sensitive spinal dura. Atrophy of these muscles is associated with chronic headache in some patients. The authors suspect that the significance of atrophy in the RCP muscles has been undervalued because the functional role of these muscles is not well defined.

Objective: To determine whether a statistically significant change in normalized levels of electromyographic activity in RCP muscles occurs when the head is voluntarily moved from a self-selected neutral head position to a protruded head position.

Methods: Fine wire, intramuscular electrodes were used to collect electromyographic data as asymptomatic participants moved their head from a neutral head position into a forward head position and back into the neutral head position. This sequence was repeated 4 times. Normalized levels of electromyographic activity were quantified using a 2-head position × 2 sides of the body repeated measures design that incorporated mixed-effects β regression models.

Results: Twenty participants were studied. Electromyographic activity collected from RCP muscles was found to increase as the head was voluntarily moved from a self-selected neutral head position (11% of maximum voluntary isometric contraction [MVIC] in RCP minor, 14% of MVIC in RCP major) into a protruded head position (35% of MVIC in RCP minor, 39% of MVIC in RCP major) (P<.001).

Conclusion: Rectus capitis posterior muscles may contribute to segmental stabilization of the occipitoatlantal and atlantoaxial joints by helping to maintain joint congruency during movement of the head.
Delirium Update for Postacute Care and Long-Term Care Settings: A Narrative Review
Authors: Forsberg Martin M. 
Published: January 2017

AbstractAdvances have been made in our understanding of the neuropathogenesis, recognition, and strategies for reducing the incidence of delirium in acute-care settings. However, relatively little attention has been given to delirium in elderly patients in the postacute care (PAC) and long-term care (LTC) settings. The present article reviews the most relevant current research pertaining to this population. Hospital patients with delirium are often discharged to PAC settings. Delirium that develops in the LTC setting is often more insidious and subtle in presentation. Despite incorporating systematic screening tools for delirium in PAC and LTC settings, delirium prevention strategies have not yet been shown to be beneficial beyond the acute-care setting. The management of delirium combined with dementia and guidance on when it is appropriate to use antipsychotic medications is also discussed.

The adaptative bleaching hypothesis (ABH) states that, depending on the symbiotic flexibility of coral hosts (i.e., the ability of corals to “switch” or “shuffle” their algal symbionts), coral bleaching can lead to a change in the composition of their associatedSymbiodiniumcommunity and, thus, contribute to the coral’s overall survival. In order to determine the flexibility of corals, molecular tools are required to provide accurate species delineations and to detect low levels of coral-associatedSymbiodinium. Here, we used highly sensitive quantitative (real-time) PCR (qPCR) technology to analyse five common coral species from Moorea (French Polynesia), previously screened using only traditional molecular methods, to assess the presence of low-abundance (background)Symbiodiniumspp. Similar to other studies, each coral species exhibited a strong specificity to a particular clade, irrespective of the environment. In addition, however, each of the five species harboured at least one additionalSymbiodiniumclade, among clades A–D, at background levels. Unexpectedly, and for the first time in French Polynesia, clade B was detected as a coral symbiont. These results increase the number of known coral-Symbiodiniumassociations from corals found in French Polynesia, and likely indicate an underestimation of the ability of the corals in this region to associate with and/or “shuffle” differentSymbiodiniumclades. Altogether our data suggest that corals from French Polynesia may favor a trade-off between optimizing symbioses with a specificSymbiodiniumclade(s), maintaining associations with particular background clades that may play a role in the ability of corals to respond to environmental change.

Published: January 2017

AbstractFrom the late 1990s to mid‐2010, Australia was affected by a prolonged period of drought, the “Millennium Drought,” during which numerous severe dust storms crossed the continent. We inspect this period to produce the first continental‐scale climatology of air‐parcel trajectories that is specific to dust and use it to gain new insights into dust transport dynamics over the eastern half of Australia. The analysis is based upon dust arrival times from airport meteorological observations made at nine mostly coastal cities for 2000–2009. The Hybrid Single‐Particle Lagrangian Integrated Trajectory model was used to calculate 1.26 million backward trajectories from receptor cities, with only those trajectories associated with a dust storm observation considered in the analysis of dust transport. To tie dust trajectories from receptors to likely emission sources, trajectories were linked to six known major dust source regions in and around the Lake Eyre Basin. The Lake Eyre North ephemeral lake system, alluvial‐dominated Channel Country, and agricultural Mallee‐Riverina regions emerge as important sources for the period, providing variable contributions to different parts of the seaboard as controlled by different front‐related wind systems. Our study also provides new detail regarding dust pathways from continental Australia. For the Millennium Drought we identify that the broadly established Southeast Dust Path may be more accurately subdivided into three active pathways, driven by prefrontal northerly winds and a variation in the influence of frontal westerlies. The detail of these pathways has implications for dust delivery from specific Australian sources to different marine environments.

AbstractStratosphere‐to‐troposphere transport (STT) and biomass burning (BB) are two important natural sources for tropospheric ozone that can result in elevated ozone and air‐quality episode events. High‐resolution observations of multiple related species are critical for complex ozone source attribution. In this article, we present an analysis of coinciding ground‐based and airborne observations, including ozone lidar, ozonesonde, high spectral resolution lidar (HSRL), and multiple airborne in situ measurements, made on 28 and 29 June 2013 during the Southeast Nexus field campaign. The ozone lidar and HSRL reveal detailed ozone and aerosol structures as well as the temporal evolution associated with a cold front passage. The observations also captured two enhanced (+30 ppbv) ozone layers in the free troposphere (FT), which were determined from this study to be caused by a mixture of BB and stratospheric sources. The mechanism for this STT is tropopause folding associated with a cutoff upper level low‐pressure system according to the analysis of its potential vorticity structure. The depth of the tropopause fold appears to be shallow for this case compared to events observed in other seasons; however, the impact on lower tropospheric ozone was clearly observed. This event suggests that strong STT may occur in the southeast United States during the summer and can potentially impact lower troposphere during these times. Statistical analysis of the airborne observations of trace gases suggests a coincident influence of BB transport in the FT impacting the vertical structure of ozone during this case study.

Published: January 2017

AbstractCatalytic syntheses of organic sulfenamides and disulfides have great significance and value in synthetic chemistry and bioscience. To establish a versatile and efficient technology for such reactions, an aerobic oxidative coupling method for the formation of S−N and S−S bonds, using TEMPO as a catalyst and O2 as an oxidant, has been successfully developed. Reactions showed good tolerance toward various amines and thiols. Sulfenamides were produced in up to 99 % yield, while disulfides were formed in up to 97 % yield in one‐pot syntheses. Activation of the N−H bond by 2,2‐disbenzothiazoledisulfide showed the great potential in organic synthesis.
