Published: September 2017

Abstract
The aim of the study was to determine the influence of the source material and the applied S. cerevisiae strain on the concentrations of carbonyl fractions in raw spirits. Acetaldehyde was the most common aldehyde found, as it accounted for 88–92% of the total amount of aldehydes. The concentration of acetaldehyde in maize, rye and amaranth mashes was highly correlated with fermentation productivity at a given phase of the process, and reached its highest value of 193.5 mg/l EtOH in the first hours of the fermentation, regardless of the yeast strain applied. The acetaldehyde concentration decreased over the time with the decreasing productivity, reaching its lowest value at the 72nd hour of the process. The final concentration of acetaldehyde depended on the raw material used (ca 28.0 mg/l EtOH for maize mashes, 40.3 mg/l EtOH for rye mashes, and 74.4 mg/l EtOH for amaranth mashes). The effect of the used yeast strain was negligible. The overall concentration of the analyzed aldehydes was only slightly higher: ca 30.3 mg/l EtOH for maize mashes, 47.8 mg/l EtOH for rye mashes, and 83.1 mg/l EtOH for amaranth mashes.

Published: September 2017

Abstract
Bacteria play a fundamental role in the cycling of nutrients in aquatic environments. A precise distinction between active and inactive bacteria is crucial for the description of this process. We have evaluated the usefulness of Coomassie Blue G250 for fluorescent staining of protein containing potentially highly active bacteria. We found that the G250 solution has excitation and emission properties appropriate for direct epifluorescence microscopy observations. It enables fast and effective fluorescent visualization of living, protein-rich bacteria, both in freshwater environment and culture. Our results revealed that the number of G250-stained bacteria from eutrophic lake was positively correlated with other standard bacterial activity markers, like number of bacteria containing 16S rRNA, bacterial secondary production or maximal potential leucine-aminopeptidase activity. In case of the E. coli culture, the percentage of bacteria visualized with G250 was similar to that of bacteria which accumulated tetracycline. Compared to other common methods utilizing fluorogenic substances for bacteria staining, the approach we evaluated is inexpensive and less hazardous (for example mutagenic) to the environment and researchers. It can be regarded as an additional or alternative method for protein rich, active bacteria staining.

Abstract
Investigations of bacterial communities and characterization of mineralogy of the environment in the Złoty Stok As-Au deposit were carried out. PXRD analysis revealed the presence of picropharmacolite as the most common secondary arsenic mineral in the mine. Total DNA was extracted from slime streams or slime biofilms samples to investigate the bacterial communities. PCR amplification of 16S rDNA was performed followed by subcloning of its products. Over 170 clones were analyzed by means of RFLP method. Eight group of clones representing different restriction patterns were identified. The nucleotide sequences of their inserts suggest that bacteria present in the mine environment belong to: Flavobacteria, Sphingobacteriia, Bacteroides, Proteobacteria, Mollicutes and Firmicutes. The metagenomic approach allows to demonstrate a higher diversity of microbiota than classical microbiological studies of cultivable isolates.

Published: September 2017

Este artigo tem como objetivo promover a visualização acerca do panorama contemporâneo que diz respeito à utilização do aparato tecnológico característico da sociedade em rede a partir da perspectiva da emergência de novas doenças relacionadas à essa expertise tecnológica. Assim, pretende-se explorar a relação existente entre as novas tecnologias informacionais e verificar se existe a sua relação direta com os novos distúrbios de saúde observados hodiernamente. Nesse sentido, para a feitura do presente trabalho optou-se pela utilização do método de abordagem indutivo, partindo de uma concepção mais restrita, baseada na perspectiva da morfologia da sociedade em rede, alargando-se tal prerrogativa para a observância das novas doenças ocasionadas por esse uso constante de tecnologias no cotidiano dos indivíduos. Também se utilizou o método de procedimento funcionalista, consubstanciado com a técnica de pesquisa baseada em fonte documental e pesquisa bibliográfica. Por fim, restou verificada a emergência de novas doenças em decorrência da utilização maciça e potencial das novas tecnologias digitais, como as Tecnologias da Informação e Comunicação (TIC), o que flagrantemente provoca e traz à tona um iminente novo problema de saúde pública, o que deixa claro a imediata necessidade de uma estruturação moderna e eficaz dos mecanismos de saúde para tratar desse tipo de nova ocorrência, característica de uma sociedade em rede.
DETERMINANTES SOCIAIS E TERRITÓRIO EM SUA INTER-RELAÇÃO COM AS FAMÍLIAS E OS PROCESSOS DE SAÚDE-DOENÇA
Authors: Jacques Carla Oliveira , Leal Graziela Milani 
Published: September 2017

No contexto sócio-histórico de apreensão e intervenção no processo de saúde-doença, apesar de todos os avanços no campo do marco legal, ainda figura como um desafio para a realidade brasileira a materialização e implementação integral dos princípios norteadores preconizados pelo Sistema Único de Saúde (SUS). Tensionados pelo contexto neoliberal que configura o papel do Estado em sua intervenção mínima e a intensificação das expressões da questão social, não raras vezes a responsabilidade por atender às demandas por proteção social recaem em uma culpabilização e estigmatização sobre as famílias. Desta forma, este artigo busca problematizar o movimento de apreensão sócio-histórica do processo saúde-doença e sua relação com as famílias, sobretudo, sob a ótica de sua materialidade socioespacial e de seus determinantes sociais, mediadas por meio das políticas públicas.
L’École du fort Frontenac (1676)
Authors: Gervais Gaétan 
Published: September 2017

Gaétan Gervais sonde les fondements historiques de la fameuse « école mère » du fort Frontenac (aujourd’hui Kingston). Cette institution, que Cavelier de la Salle y aurait fait construire, en 1676 ou 1678, pour l’instruction de la population qui y séjournait et confiée aux récollets, aurait été le premier établissement d’enseignement de l’Ontario. Analysant tour à tour les caractéristiques qu’on supposait à cette petite école et les arguments avancés par Arthur Godbout, qui se fit le principal diffuseur de cette thèse, il en trouve les sources chez trois historiens de la fin du xixe et du début du xxe siècle (Louis Le Jeune, Camille de Rochemonteix et Benjamin Sulte) et la reconnaissance officielle par trois groupes de chercheurs de la mouvance pédagogique qui tous, à une exception près, ont accepté cette hypothèse sans sourciller (historiens, chercheurs et pédagogues) et l’ont colportée, jusqu’à tout récemment, en amplifiant même le « fait ». Après avoir aussi noté les « lourds silences » des groupes d’acteurs (militants, historiens, compilateurs et récollets) qui n’auraient pas manqué de relever une telle réalité, Gervais conclut qu’il n’y a jamais eu d’école au fort Frontenac et que cette thèse appartient au monde du mythe : elle s’accordait si bien aux revendications scolaires que défendait Godbout et qu’ont soutenues, après lui, d’autres chercheurs engagés, pourtant mieux outillés, que l’idée d’une remise en cause n’effleura aucun de ces militants.
Fidélité à soi et au devenir franco-ontarien : Fernand Dorais essayiste
Authors: Gaulin Michel 
Published: September 2017

Michel Gaulin propose de « faire le point sur l’essentiel de la pensée » de Fernand Dorais, telle qu’il l’a pu dégager des deux recueils d’essais publiés par ce dernier : Entre Montréal... et Sudbury et Témoins d’errances en Ontario français. Il met en perspective l’activité de ce professeur de littérature de l’Université Laurentienne et la réflexion que l’essayiste entretint sur son métier de pédagogue et sur la matière qui était sienne. Il aborde ainsi la conception de la littérature de ce « penseur provocant » et l’idée qu’il se faisait du « devenir franco-ontarien ». Cet article est un hommage que Michel Gaulin rend à l’actualité des idées de cet auteur.
Coup d’oeil sur le répertoire traditionnel d’un chanteur franco-ontarien
Authors: Pichette Jean-Pierre 
Published: September 2017

Jean-Pierre Pichette explore la littérature orale franco-ontarienne dans cet article consacré au répertoire des chansons de Donat Paradis, un nonagénaire à la mémoire alerte qu’il a eu le privilège de rencontrer et d’interroger de façon brève mais intensive en 1982. Il expose d’abord les circonstances du collectage de ces oeuvres lyriques, montre aussi le rôle du réseau familial dans l’apprentissage et la transmission des chansons, et fait une analyse sommaire des types poétiques et des thèmes récurrents. Après quoi, il en dégage quelques éléments caractéristiques et en fait voir l’originalité ; franco-ontarien et blézardois par la géographie, familial et vicinal par l’inspiration, paysan par le milieu social, ce répertoire paraît tout à fait représentatif de la tradition canadienne-française. Sa recherche s’inscrit dans les travaux préparatoires à l’édition intégrale du chansonnier Paradis.
1910. Une première prise de parole collective en Ontario français
Authors: Dionne René 
Published: September 2017

René Dionne, pionnier des études littéraires franco-ontariennes à l’Université d’Ottawa, se penche sur un texte fondateur de l’identité franco-ontarienne : les actes du Congrès d’éducation des Canadiens-Français d’Ontario tenu à Ottawa en 1910. Par le compte rendu fidèle et détaillé qu’il en donne, il réaffirme le long passé littéraire franco-ontarien, dont la prise de parole actuelle n’est qu’un épisode, puisqu’il a dénombré plus de deux cents oeuvres écrites par vingt-quatre écrivains outaouais qui prirent individuellement la parole entre 1865 et 1909. Puis il compare ce congrès aux grandes conventions nationales (la franco-américaine, les québécoises et les acadiennes) pour mieux marquer l’originalité du congrès franco-ontarien qui, bien que tardif, fut, observe l’auteur, démocratique, provincial, national, loyal, optimiste et littéraire. Devant les conflits politiques et religieux qui menaçaient de dégénérer, l’heure était à la vigilance et à la cohésion; la prise de parole de 1910 se devait d’être collective.

AbstractWe describe the physiological responses of boreal conifers to climate change for the past 112 years using ring‐width and carbon isotope ratio (δ13C) chronologies at six forest sites in northern Eurasia and Canada. Responses differed among regions, depending on their climatic and/or geographic characteristics. Tree radial growth decreased over the past 52 years in central eastern Siberia with the higher rate of summer temperature increase than other regions, as indicated by the negative correlation between radial growth and summer temperature, but increased in northern Europe and Canada. Changes in tree‐ring δ13C indicated that recent climatic conditions have induced stronger drought stress for trees from central eastern Siberia than for those from other regions. The observed tree growth trends were compared to those simulated using a dynamic global vegetation model. Although the modeled annual net primary production (NPP) for trees generally exhibited similar decadal variation to radial growth, simulations did not show a recent decrease in tree growth, even in central eastern Siberia. This was probably due to an overestimation of the sensitivity of modeled tree NPP to precipitation. Our results suggest that the tree NPP forecasted under the expected future increases in temperature and average precipitation might be overestimated, especially in severely dry regions such as central eastern Siberia.
Simultaneous Measurements of Substorm‐Related Electron Energization in the Ionosphere and the Plasma Sheet

Published: September 2017

AbstractOn 26 March 2008, simultaneous measurements of a large substorm were made using the Poker Flat Incoherent Scatter Radar, Time History of Events and Macroscale Interactions during Substorm (THEMIS) spacecraft, and all sky cameras. After the onset, electron precipitation reached energies ≳100 keV leading to intense D region ionization. Identifying the source of energetic precipitation has been a challenge because of lack of quantitative and magnetically conjugate measurements of loss cone electrons. In this study, we use the maximum entropy inversion technique to invert altitude profiles of ionization measured by the radar to estimate the loss cone energy spectra of primary electrons. By comparing them with magnetically conjugate measurements from THEMIS‐D spacecraft in the nightside plasma sheet, we constrain the source location and acceleration mechanism of precipitating electrons of different energy ranges. Our analysis suggests that the observed electrons ≳100 keV are a result of pitch angle scattering of electrons originating from or tailward of the inner plasma sheet at ~9RE, possibly through interaction with electromagnetic ion cyclotron waves. The electrons of energy 10–100 keV are produced by pitch angle scattering due to a potential drop of ≲10 kV in the auroral acceleration region (AAR) as well as wave–particle interactions in and tailward of the AAR. This work demonstrates the utility of magnetically conjugate ground‐ and space‐based measurements in constraining the source of energetic electron precipitation. Unlike in situ spacecraft measurements, ground‐based incoherent scatter radars combined with an appropriate inversion technique can be used to provide remote and continuous‐time estimates of loss cone electrons in the plasma sheet.
The Modulation of the Quasi‐Two‐Day Wave on Total Electron Content as Revealed by BeiDou GEO and Meteor Radar Observations Over Central China

Published: September 2017

AbstractThe ground‐based total electron content (TEC) observations from BeiDou Geostationary Orbit (GEO) satellites provide more accurate temporal ionospheric variations nearly at the fixed ionospheric pierce points as compared with the non‐GEO TEC. BeiDou GEO TEC measurements during 2016, along with the horizontal wind observations from a collocated meteor radar, are utilized to quantitatively study the ionospheric response to the quasi‐two‐day wave (QTDW) in the neutral atmosphere at Meng Cheng (116.6°E, 33.3°N) over central China. The QTDW peaks during July with amplitudes of ~25–30 m/s for both zonal and meridional winds. It is suggested that the nonlinear interactions between the QTDW and tides and their influences on TEC are insignificant for this QTDW event. Nevertheless, the diurnal tide decreases by ~40–60% during the QTDW episode, which is most likely related to the change of background wind induced by the QTDW. Correspondingly, the 24 h oscillations in TEC decrease by ~18%. In addition, the wind perturbations of the QTDW can also possibly modulate the midlatitude electric dynamo and result in a quasi‐two‐day oscillation (QTDO) of ~1.2 total electron content unit (TECU), about ~10% of the background TEC. Our analysis also shows that the background TEC decreases by ~1 TECU (~8%) when the QTDW reaches maximum amplitude. This is probably related to the thermospheric composition changes (e.g., O and N2) induced by the QTDW dissipation.
Interesting Equatorial Plasma Bubbles Observed by All‐Sky Imagers in the Equatorial Region of China

Published: September 2017

AbstractThis paper reports some interesting equatorial plasma bubbles (EPBs) on 4 and 5 October 2013 and 29 and 30 September 2013 observed by two all‐sky imagers located in the magnetically equatorial region of Hainan (19.5°N; 9.5° geomagnetic latitude) and Guiping (23.8°N; 13.9° geomagnetic latitude), China. The case of 4 and 5 October 2013 shows the following: (1) EPBs had planar wave‐like structures and their wavefronts were parallel to each other before midnight. (2) The angle between the wavefronts of those EPBs and the geomagnetic meridian were ~30°. (3) Near midnight, the higher‐latitude part of one EPB suddenly began to rotate with a large eastward zonal drift, resulting in an unusual C‐shaped EPB that was observed for the first time by an all‐sky imager. (4) After midnight, one EPB merged into another EPB and formed an integrated EPB. The other EPB case on 29 and 30 September 2013 shows the following: (1) The images captured the full evolution processes of an “I” shaped EPB with an angle of ~30° with respect to the geomagnetic meridian. The imagers also observed “S” and “Y” shaped EPBs. (2) The change of EPBs' shape was directly related to the change of EPBs' zonal drift velocities. (3) The angle between the I‐shaped EPBs and the geomagnetic meridian was likely caused by the change of the latitudinal gradient of zonal neutral wind velocities and ionospheric conductivity. (4) The zonal velocity of each branch of the “Y” shape EPB was different, which could be related to the polarization electric fields within each branch.

AbstractThe Southern Ocean (SO) hosts plankton communities that impact the biogeochemical cycles of the global ocean. However, weather conditions in the SO restrict mainly in situ observations of plankton communities to spring and summer, preventing the description of biological successions at an annual scale. Here, we use shipboard observations collected in the Indian sector of the SO to develop a multivariate relationship between physical and bio‐optical data, and, the composition and carbon content of the plankton community. Then we apply this multivariate relationship to five biogeochemical Argo (BGC‐Argo) floats deployed within the same bio‐geographical zone as the ship‐board observations to describe spatial and seasonal changes in plankton assemblage. The floats reveal a high contribution of bacteria below the mixed layer, an overall low abundance of picoplankton and a seasonal succession from nano‐ to microplankton during the spring bloom. Both naturally iron‐fertilized waters downstream of the Crozet and Kerguelen Plateaus show elevated phytoplankton biomass in spring and summer but they differ by a nano‐ or microplankton dominance at Crozet and Kerguelen, respectively. The estimated plankton group successions appear consistent with independent estimations of particle diameter based on the optical signals. Furthermore, the comparison of the plankton community composition in the surface layer with the presence of large mesopelagic particles diagnosed by spikes of optical signals provides insight into the nature and temporal changes of ecological vectors that drive particle export. This study emphasizes the power of BGC‐Argo floats for investigating important biogeochemical processes at high temporal and spatial resolution.
Physicochemical and Biological Controls on Carbon and Nitrogen in Permafrost from an Ultraxerous Environment, McMurdo Dry Valleys of Antarctica

Published: September 2017

AbstractLittle is known about the abundance and source of soil organic carbon and biogeochemical cycling in permafrost soils from the ultraxerous environment of the Dry Valleys of Antarctica. Here we investigate the distribution, source and cycling of organic carbon, total nitrogen and carbonates in the icy permafrost soils of University Valley, Quartermain Mountains. Results indicate that organic carbon content is lowest in icy soils from the perennially cryotic zone (<40 μg g−1 dry soils) and higher in the icy soils from the seasonally noncryotic zone, where the highest concentrations were found in the warmer‐wetter section of the valley and near a frozen pond (up to 313 μg g−1 dry soils). The δ13Corg of organic carbon in the icy soils showed that it is derived from the weathering of Beacon Supergroup sandstone that hosts active endolithic communities. The C:N ratios in icy soils formed two populations: one with ratios <5 and the other with ratios near the Redfield ratios. The low C:N ratios suggest that physicochemical processes dominates these soils, as supported by the absence of microbial activity and atmospherically deposited NO3 with minimal postdeposition modification. The near Redfield C:N ratios can be explained by physical processes (translocation of SOC in the soils from snow meltwater) or balanced microbial activity. The latter is supported by the δ13CCaCO3 values of carbonates that suggest a contribution from microbially respired endolith‐derived organic matter, providing indirect evidence of heterotrophic activity in permafrost soils from an ultraxerous environment.
