Authors: Ridley Jeff K. , Blockley Edward W. , Keen Ann B. , Rae Jamie G. L. , West Alex E. , Schroeder David 
Published: February 2018

Abstract. A new sea ice configuration, GSI8.1, is implemented in the Met Office global coupled configuration HadGEM3-GC3.1 which will be used for all CMIP6 (Coupled Model Intercomparison Project Phase 6) simulations. The inclusion of multi-layer thermodynamics has required a semi-implicit coupling scheme between atmosphere and sea ice to ensure the stability of the solver. Here we describe the sea ice model component and show that the Arctic thickness and extent compare well with observationally based data.

Published: February 2018

In the processes of agricultural products production a sufficiently large amount of solid wastes which contain high molecular weight hydrocarbons such as lignin, cellulose, etc. is accumulated. However, such wastes are rarely used to produce active carbons, and only technologies with their use for obtaining crushed or powdered sorption materials are known. In the industrial production of granular activated carbon the fossil coals are mainly used. In this work, research was conducted on the development of methods for producing granulated active carbon of spherical form. And the characteristics of their porous structure were studied. The process of granulation of the spherical shape of sorbents was carried out by liquid dispersing composition containing pulverized wastes of vegetable origin and a binder. As plant materials we used walnut shells and peanuts, apricot seed, buckwheat husk, and for comparison, the dust caking coal of SSOM brand. As a binder a phenol formaldehyde resin was used. To remove volatile substances of plant the raw material was subjected to preliminary heat treatment without access of air in a muffle furnace at optimum temperature which was determined by thermogravimetry. Crushed carbon material was mixed with a binder component in a weight ratio of 1:5 and was sprayed into a solution of sulfuric acid with a concentration of 30-35% for the curing of the pellets. The obtained pellets were soaked in acid solution for 24-30 h, were separated from the liquid, were washed with distilled water to pH = 5-6, and were dried first in air and were subjected to heat treatment. The result of the research shows the possibility of regulation of characteristics of the porous structure of the spherical granular activated carbon depending on the plant material. The resulting spherical granules of activated carbon have developed system of micro - and mesopores. Depending on the type of plant waste the received active carbon has a radius of micropores in the range of (0.527-0.635) nm and maximum sorption volume varied from 0.46 to 0.71 cm3/g.Forcitation:Farberova E.A., Tingaeva E.A., Chuchalina A.D., Kobeleva A.R., Maximov A.S.

Authors: IsaBelle Claire , Martineau Vachon Hélène 
Published: February 2018

Les avantages de travailler en communauté d’apprentissage professionnelle dans les écoles sont nombreux. Toutefois, les directions semblent avoir des habiletés limitées pour implanter ce nouveau mode de fonctionnement. Afin d’identifier les composantes de la compétence nécessaires pour instaurer et faire progresser ce nouveau mode de fonctionnement, une étude qualitative, par entrevues, a été menée auprès de 15 directions d’école de trois provinces canadiennes. Une thématisation mixte appuyée du logicielQDA Minera été utilisée pour analyser les données. La majorité des participants ont cité trois habiletés : articuler une vision et assumer un leadership pédagogique, développer une culture de confiance et de collaboration, et diriger. De plus, une attitude a été soulignée par plusieurs participants : être à l’écoute des enseignants et accepter les erreurs. Quant aux connaissances, les nouvelles pédagogies et les pratiques efficaces ont été nommées par peu de participants.
La gestion commune au sein des couples : une question de mariage ou pas ?
Authors: Belleau Hélène , Lavallée Carmen , Seery Annabelle 
Published: February 2018

Dans plusieurs pays, on observe que les couples mariés tendent à gérer ensemble leur argent alors que les couples en union libre sont plus enclins à le gérer séparément. L’objectif de cet article est de déterminer si ces différences sont aussi présentes au Québec où les unions libres sont largement répandues et d’identifier d’autres variables que l’état matrimonial pour expliquer ces différences. L’étude s’appuie sur une enquête québécoise inédite (n = 3246) réalisée en 2015 par Belleau et collab. (2017) et portant sur les arrangements économiques des couples et les enjeux juridiques qui s’y rattachent. Les résultats de deux analyses de régression logistique confirment l’existence d’un modèle explicatif permettant de mieux comprendre la mise en commun des revenus qui tient compte de variables telles que : la durée de la vie commune, la présence d’enfant commun, le fait d’être copropriétaire et les connaissances juridiques. Les auteures soulignent qu’il est impératif que les lois privées, sociales et fiscales soient adaptées aux situations réelles des couples du Québec, peu importe qu’ils soient mariés ou non.

Anther development in tribe Epidendreae: orchids with contrasting pollination syndromes
Authors: Valencia-Nieto Benjamín , Sosa Victoria , Márquez-Guzmán Judith 
Published: February 2018

BackgroundEpidendreae is one of the most diverse tribes among the orchids with remarkable variation in life form, floral morphology and pollination syndromes. Its circumscription was recently revised and subtribes Agrostophyllinae and Calypsoinae were transferred into this tribe. One of the principal floral characters utilized in classification of orchids is the incumbency or bending of the column. This study records and compares late stages of anther, column and lip development, and discusses anther characters in fifteen representative taxa of five of the six subtribes in Epidendreae with respect to classification and pollination biology.MethodsA series of late floral stages were sampled and fixed for examination under scanning electron microscope.ResultsAnther incumbency or bending in this group varies from 90° to almost 180°. Incumbency in the late stages of development is reached in Bletiinae, Ponerinae, Pleurothallidinae and Laeliinae whereas incumbency is reached early in its development inCorallorhizaandGoveniaof Calypsoinae.DiscussionOur observations indicate that the position ofChysisin subtribe Bletiinae needs revision based on differences in a number floral, and in particular of anther characters; and thatCoeliaonly shares the early anther incumbency with Calypsoinae members, but not the rest of floral and anther characters. Anatomical characters such as crystals around the actinocytic stomata on the anther cap and sugar crystals in Laeliinae; lack of rostellum in Bletiinae; coalescent anther with the column, lack of trichomes and papillae on lip keels, and underdeveloped rostellum inChysis; a mechanism by which the anther cap comes off (it is joined with the grooved lip by a claw) inIsochilusare all related to pollination syndromes and reproductive biology.

<p>Resenha-se o livro de Mauri Iasi, lançado neste ano de 2017 pela Instituto Caio Prado Jr., intitulado <em>Política, Estado e ideologia</em> na trama conjuntural. Esta obra é composta por duas partes: a primeira de cunho teórico e a segunda com temas da conjuntura dos governos do partido dos trabalhadores (PT). Em virtude da abordagem teórica dos temas tratados esta obra pode ser incluída no conjunto daquelas que de algum modo lembram e festejam os cem anos da Revolução Russa de outubro de 1917. Por conta disso, fazem-se apontamentos sobre as contribuições da referida Revolução a todo o século XX. As relações entre a obra de Iasi e a Revolução Russa impõe considerar a categoria longa duração, um século, contribuição da Escola dos Annales (1929), na sua primeira geração, afinal, lá como cá um espectro ronda o mundo – o comunismo. A obra de Iasi trata dos temas com rigor, algumas vezes com heroína, sempre com erudição e compromisso político revolucionário. </p><p> </p>

The introduction of tyrosine kinase inhibitors (TKI) has transformed chronic myeloid leukemia (CML) into a chronic disease with long‐term survival exceeding 85%. However, resistance of CML stem cells to TKI may contribute to the 50% relapse rate observed after TKI discontinuation in molecular remission. We previously described a model of resistance to imatinib mesylate (IM), in which K562 cells cultured in high concentrations of imatinib mesylate showed reduced Bcr‐Abl1 protein and activity levels while maintaining proliferative potential. Using quantitative phosphoproteomic analysis of these IM‐resistant cells, we have now identified significant upregulation of tumor progression locus (Tpl2), also known as cancer Osaka thyroid (COT1) kinase or Map3k8. Overexpression of Tpl2 in IM‐resistant cells was accompanied by elevated activities of Src family kinases (SFKs) and NF‐κB, MEK‐ERK signaling. CD34+ cells isolated from the bone marrow of patients with CML and exposed to IMin vitro showed increased MAP3K8 transcript levels. Dasatinib (SFK inhibitor), U0126 (MEK inhibitor), and PS‐1145 (IκB kinase (IKK) inhibitor) used in combination resulted in elimination of 65% of IM‐resistant cells and reduction in the colony‐forming capacity of CML CD34+ cells in methylcellulose assays by 80%. In addition, CML CD34+ cells cultured with the combination of inhibitors showed reduced MAP3K8 transcript levels. Overall, our data indicate that elevated Tpl2 protein and transcript levels are associated with resistance to IM and that combined inhibition of SFK, MEK, and NF‐κB signaling attenuates the survival of IM‐resistant CML cells and CML CD34+ cells. Therefore, combination of SFK, MEK, and NF‐κB inhibitors may offer a new therapeutic approach to overcome TKI resistance in CML patients.
Present and Future Mercury Concentrations in Chinese Rice: Insights From Modeling

Published: February 2018

AbstractWe construct a rice paddy biogeochemical cycle model to investigate processes governing rice mercury sources and to understand factors influencing spatiotemporal variability in Chinese rice mercury concentrations. The rice paddy model takes atmospheric mercury deposition, simulated from a global atmospheric chemistry transport model (GEOS‐Chem), and soil and irrigable surface water mercury concentrations obtained from literature and calculates rice inorganic (IHg) and methylmercury (MeHg) concentrations. We use ranges of GEOS‐Chem‐simulated future atmospheric mercury deposition—no policy and strict policy to regulate mercury emissions from Chinese coal‐fired power plants under the Minamata Convention on Mercury—to simulate future rice IHg and MeHg concentrations. Sensitivity analyses suggest that rice IHg and MeHg concentrations are more sensitive to the process of soil desorption than infiltration of recently introduced mercury (atmospheric and irrigation source). The rate of internal methylation via microbial activity has the largest modeled influence on rice MeHg concentration. We find that soil mercury, rather than atmospheric deposition, explains observed spatial variability in rice IHg and MeHg concentrations and captures locations of rice mercury hot spots (>20 ng/g; China National Standard Limit). Under our future scenarios, the Chinese median rice IHg and MeHg concentration increases by 13% and decrease by 18% under no policy and strict policy, respectively. Regions with the largest percentage decline in rice IHg and MeHg concentrations under strict policy are in central China, which have high rice mercury concentrations, rice production, and consumption. Our study suggests that addressing Chinese rice mercury contamination requires attention to contaminated soil and regulation of anthropogenic mercury emissions.
Mixing of Felsic Magmas in Granite Petrogenesis: Geochemical Records of Zircon and Garnet in Peraluminous Granitoids From South China

Published: February 2018

AbstractMixing of felsic magmas from different sources may be common in granite petrogenesis, but challenging to unravel. Nevertheless, this is identified by a combined study of in situ zircon and garnet geochemistry with whole‐rock geochemistry for the Jiuling batholith in South China. The Jiuling batholith is composed of low‐Si granitoids and high‐Si granites. Although they show similar whole‐rock Sr‐Nd‐Hf isotope compositions, the low‐Si granitoids exhibit higher MgO, FeO, TiO2, Al2O3, and Middle rare earth elements contents, and higher Zr saturation temperature than the high‐Si granites. Two groups of zircons and garnets are identified in the form of either individual grains or different domains of a grain. Although they exhibit highly variable O and Hf isotope compositions, Group I zircons show higher δ18O and lower εHf(t) values than Group II zircons. Group I garnets are higher in FeO and MgO but lower in CaO and MnO than Group II garnets. Group I garnets show more remarkable negative Eu anomalies than Group II garnets. Groups I and II garnets exhibit distinct δ18O values, in equilibrium with Groups I and II zircons, respectively. These differences indicate that the two groups of zircons and garnets were derived from two different batches of felsic magmas. Batch I magma may be derived from partial melting of ancient sedimentary rocks at higher temperature, whereas Batch II magma would probably form by partial melting of relatively juvenile crust at lower temperature. Therefore, the Jiuling batholith is produced by mixing between two batches of granitic magmas with different trace element and isotope compositions.
A Century of Stability of Avannarleq and Kujalleq Glaciers, West Greenland, Explained Using High‐Resolution Airborne Gravity and Other Data

Published: February 2018

AbstractThe evolution of Greenland glaciers in a warming climate depends on their depth below sea level, flow speed, surface melt, and ocean‐induced undercutting at the calving front. We present an innovative mapping of bed topography in the frontal regions of Sermeq Avannarleq and Kujalleq, two major glaciers flowing into the ice‐choked Torssukatak Fjord, central west Greenland. The mapping combines a mass conservation algorithm inland, multibeam echo sounding data in the fjord, and high‐resolution airborne gravity data at the ice‐ocean transition where other approaches have traditionally failed. We obtain a reliable, precision (±40 m) solution for bed topography across the ice‐ocean boundary. The results reveal a 700 m deep fjord that abruptly ends on a 100–300 m deep sill along the calving fronts. The shallow sills explain the presence of stranded icebergs, the resilience of the glaciers to ocean‐induced undercutting by warm Atlantic water, and their remarkable stability over the past century.
Cytoprotective activity of mitochondrial uncoupling protein‐2 in lung and spleen
Authors: Jabůrek Martin , Ježek Jan , Ježek Petr 
Published: February 2018

Mitochondrial uncoupling protein‐2 (UCP2) mediates free fatty acid (FA)‐dependent H+ translocation across the inner mitochondrial membrane (IMM), which leads to acceleration of respiration and suppression of mitochondrial superoxide formation. Redox‐activated mitochondrial phospholipase A2 (mt‐iPLA2γ) cleaves FAs from the IMM and has been shown to acts in synergy with UCP2. Here, we tested the mechanism of mt‐iPLA2γ‐dependent UCP2‐mediated antioxidant protection using lipopolysaccharide (LPS)‐induced pro‐inflammatory and pro‐oxidative responses and their acute influence on the overall oxidative stress reflected by protein carbonylation in murine lung and spleen mitochondria and tissue homogenates. We provided challenges either by blocking the mt‐iPLA2γ function by the selective inhibitor R‐bromoenol lactone (R‐BEL) or by removing UCP2 by genetic ablation. We found that the basal levels of protein carbonyls in lung and spleen tissues and isolated mitochondria were higher in UCP2‐knockout mice relative to the wild‐type (wt) controls. The administration of R‐BEL increased protein carbonyl levels in wt but not in UCP2‐knockout (UCP2‐KO) mice. LPS further increased the protein carbonyl levels in UCP2‐KO mice, which correlated with protein carbonyl levels determined in wt mice treated with R‐BEL. These results are consistent with the UCP2/mt‐iPLA2γ antioxidant mechanisms in these tissues and support the existence of UCP2‐synergic mt‐iPLA2γ‐dependent cytoprotective mechanism in vivo.
Electrical Double‐Slope Nonideality in Organic Field‐Effect Transistors

Published: February 2018

AbstractThe field effect transistor (FET) is arguably one of the most important circuit elements in modern electronics. Recently, a need has developed for flexible electronics in a variety of emerging applications. Examples include form‐fitting healthcare‐monitoring devices, flexible displays, and flexible radio frequency identification tags. Organic FETs (OFETs) are viable candidates for producing such flexible devices because they incorporate semiconducting π‐conjugated materials, including small molecules and conjugated polymers, which are intrinsically soft and mechanically compatible with flexible substrates. For OFETs to be industrially viable, however, they must achieve not only high charge carrier mobility, but also ideal and comprehensible electrical characteristics. Most recently, nonideal double‐slope characteristics in the transfer curves of OFETs (i.e., high slope at low gate voltage and low slope at high gate voltage), have stirred debate, which has led to different mechanistic rationales in the literature. This review focuses on the general observations, mechanistic understanding, and possible solutions associated with phenomena that result in FETs with double‐slope characteristics. By surveying and systematically summarizing in a single source relevant literature that deals with the issue of double slope, the experimental framework and theoretical basis for interpreting and avoiding this electrical nonideality in OFETs is provided.
