Abstract
The 2698 Ma LaRonde Penna deposit, with over 71 Mt of ore at 3.9 g/t Au (280 t Au or ~9 Moz Au), is the second largest Au-rich volcanogenic massive sulfide (VMS) deposit in the world. It is part of the Doyon-Bousquet-LaRonde mining camp in the eastern part of the Blake River Group.
The deposits of the Doyon-Bousquet-LaRonde mining camp are hosted by the volcanic rocks of the Hébé-court (base) and Bousquet (top) formations that form a southward-younging homoclinal sequence, with nearly vertical dips due to a north-south compressional event responsible for the development of an E-W–trending, steeply S-dipping, penetrative schistosity under prograde, upper greenschist to lower amphibolite facies meta-morphism. The E-trending, steeply S-dipping schistosity is associated with strong flattening, transposition, and minor folding of the volcanic rocks, alteration zones, and sulfide lenses.
The ore lenses at LaRonde Penna, which are stacked in the upper half of the Bousquet Formation, are characterized by semimassive to massive sulfides or narrow intervals of transposed sulfide veins and veinlets. The synvolcanic hydrothermal alteration at LaRonde Penna now corresponds to mappable upper greenschist-lower amphibolites-grade metamorphic assemblages.
In the upper part of the deposit, the 20 North lens comprises a transposed pyrite-chalcopyrite (Au-Cu) stockwork (20N Au zone) overlain by a pyrite-sphalerite-galena-chalcopyrite-pyrrhotite (Zn-Ag-Pb) massive sulfide lens (20N Zn zone). The 20 North lens (20N Au and 20N Zn zones) is underlain by a large, semiconformable alteration zone that comprises a proximal quartz-Mn-garnet-biotite-muscovite alteration assemblage. The 20N Zn zone tapers with depth in the deposit and gives way to the 20N Au zone. At depth in the deposit, the 20N Au zone consists of semimassive sulfides (Au-rich pyrite and chalcopyrite) enclosed by a large aluminous alteration assemblage interpreted to be the metamorphic equivalent of an advanced argillic alteration zone.
At LaRonde Penna, the presence of sulfide lenses characterized by Au-rich portions and base metal-rich portions demonstrates that a VMS system can generate mineralization styles that gradually evolve, both in space and time, from neutral (Au-Cu-Zn-Ag-Pb ore), to transitional, to acidic (advanced argillic alteration and Au ± Cu-rich ore) in response to the evolving local geologic setting.
El papel de las mujeres en los rituales religiosos y las performances políticas entre los nahuas en la época precortesiana y colonial
Authors: Szoblik Katarzyna 
Published: July 2019

El presente trabajo parte de los estudios más amplios acerca del lugar de la mujer en la oralidad nahua y se enfoca en uno de los aspectos concretos de este tema, es decir, en la variedad de papeles desempeñados por los personajes femeninos en la manifestación artística inscrita en los contextos religiosos y políticos. El análisis de los papeles de la mujer en los cantos-bailes (en nahuatl: cuicatl) registrados en varios manuscritos coloniales y en los mitos indígenas lleva a las conclusiones importantes acerca de la conceptualización idealizada de lo femenino en la cultura estudiada.
La reelaboración del mito como apropiación de la memoria andina en Baladas peruanas de González Prada
Authors: Huarcaya Gutierrez Evelyn Isamar 
Published: July 2019

En este artículo, se tiene como hipótesis que a partir de la implementación del elemento del mito dentro de la composición de las piezas poéticas de Baladas peruanas, se produce una apropiación de la memoria andina. Es decir, a través de las estrategias de textualización como la dedicatoria, la cita pórtico y el epígrafe, Prada legitima en Baladas peruanas una forma mítica de pensar el mundo y lo inserta dentro de un contexto de mayor raigambre como el europeo-occidental. Para lo cual se establecen primero vasos comunicantes entre Comentarios reales del Inca Garcilaso de la Vega y propiamente Baladas peruanas, a partir del cual se rescata el elemento del mito, se le reutiliza y recrea de una manera plástica, nueva y autónoma, conservando la matriz de los mitos prehispánicos. De esta manera, el sujeto textual se apropia de elementos de la cultura andina y su forma de ver el mundo a nivel estructural y semántico lo que deviene en una autentificación e universalización de una manera válida y diferente de concebir la historia
Desangrar. Violencia y relaciones inter-étnicas en algunos relatos de la Amazonía peruana
Authors: Pau Stefano 
Published: July 2019

La región amazónica peruana es el escenario en el que vive y actúa una terrorífica figura que se conoce como sacacara, pelacara o sacaojos. Este personaje “mítico”, percibido por los habitantes de la región como una realidad simbólica alternativa, tiene algunas características propias de su manera de obrar que lo conectan con el tigre negro o yanapuma, protagonista de otros cuentos de la tradición oral, cuya difusión se hizo más frecuente a partir de la época del llamado “boom” del caucho. En el artículo, a partir de algunos relatos orales y de algunas referencias de literatura escrita, se abordará el tema de la explotación y de las desequilibradas relaciones de poder entre poblaciones autóctonas y occidentales, sintetizadas en el paralelismo entre la extracción de la savia de los árboles de goma y la práctica del desangramiento, extraño modus occidendidel tigre negro.
La mexicanidad de Xólotl/Axolotl: Maravilla de la literatura y la gastronomía.
Authors: Holguin Fdo. Valerio 
Published: July 2019

Para los aztecas, los axólotls eran animales divinos, ya que representaban al dios Xólotl, quien escapó convirtiéndose en maíz, maguey y, luego, en axolotl, para evitar el sacrificio, pero, finalmente, fue atrapado y sacrificado. Varios escritores mexicanos han recuperado tanto a Xólotl como a Axolotl en sus textos literarios y ensayísticos. Salvador Elizondo escribe “Ambystoma trigrinum”, texto que forma parte del libro El grafógrafo. Así también Juan José Arreola publica “El ajolote”, que después sería incluido en su Bestiario. Octavio Paz recupera el sustrato mitológico del dios Xólotl en Salamandra, así como también lo hace José Emilio Pacheco en El reposo del fuego. Mi propósito en este ensayo consiste en analizar cómo el dios azteca Xólotl y su representación anfibia Axólotl han sido objeto de estudio en la imaginación científica, cultural y literaria en el México contemporáneo.
Microhistoria del relato policial. Modulaciones políticas del detective latinoamericano
Authors: Garí Barceló Bernat 
Published: July 2019

La figura del detective literario adopta distintas formas y declinaciones políticas a lo largo de su historia. La narrativa policial decimonónica ―o relato enigma― se inscribe en una matriz biopolítica y es el producto madurado de una reflexión teórica y social sobre las nuevas dinámicas del hombre moderno en el contexto de la gran ciudad. Su variante brutalizada ―el hard-boiled bosquejado por Hammet y Chandler y las distintas reformulaciones que suscita― da cuenta de un patrón reformista, agotados los presupuestos del marxismo ortodoxo y la posibilidad de una ruptura total. Finalmente, en el contexto de la posmodernidad, el metapolicial despliega una línea experimental y despolitizada. Trataré de exponerlo sumariamente en las líneas que siguen a través de algunos ejemplos seleccionados aleatoriamente.
Rozhodovanie podľa zásad spravodlivosti v prípadoch dotknutých korupciou v medzinárodnej obchodnej arbitráži
Authors: Garajová Michaela 
Published: July 2019

Rozhodovanie podľa zásad spravodlivosti v medzinárodnej obchodnej arbitráži sa stáva pomerne častým javom. Striktnosť národných pravidiel neumožňuje stranám flexibilitu v sporoch, ktorú vzhľadom na dlhotrvajúce obchodné vzťahy potrebujú. To, že sa v rozhodcovskom konaní neaplikujú národné právne predpisy neznamená, že by rozhodcovia nemali v rukách nástroje, ktoré môžu použiť v prípadoch, keď odhalia korupčné konanie strán priamo súvisiace s predmetným sporom. Rozhodcovia síce nemôžu prekročiť svoje právomoci, ale stále majú povinnosť skúmať a aplikovať verejný poriadok. Týmto sa musia riadiť aj v prípadoch, keď rozhodujú podľa zásad spravodlivosti.
O ensino de Filosofia em tempos hipermodernos: Desafios do amanhã.
Authors: Alves Mauricio Silva 
Published: July 2019

A sociedade hipermoderna tem suas estruturas fundadas na lógica do imediatismo, hedonismo, consumismo bem como no fascínio estético que torna uma sociedade alicerçada no espetáculo, este não dá subsídios que permitam o homem distinguir o que é real do que é irreal, deste modo, constitui-se um indivíduo que se imagina eterno e que não precisa cultivar a atitude perguntante diante dos aparatos inovadores e sedutores da hipermodernidade, é por assim dizer uma traição, pois fascinado pelo imediatismo, e por todos os padrões espetaculares, porém superficiais que lhe são oferecidos, é incapaz de lidar com seus problemas existenciais. A filosofia deve permanecer à margem para garantir o seu espaço como disciplina? A proposta desse trabalho é que se busque a interdisciplinaridade que se coloca como possibilidade de efetivar uma nova maneira de ensinar a Filosofia por meio da reconsideração do discurso das disciplinas do currículo e do modo como elas se articulam sobre uma mesma temática. Nesse sentido, desenvolver um Ensino de Filosofia eficaz, nesses tempos hipermodernos, pressupõe não só a utilização dos textos clássicos dos filósofos de maneira a construir uma exegese filosófica no ensino médio, mas como um distintivo que possibilite o desenvolvimento da criticidade dos alunos do Ensino Médio por meio da interdisciplinaridade.

BackgroundForage production in the saline-sodic soil of the western Songnen Plain Northeast China depends on irrigation. Therefore, the water use efficiency (WUE) and soil chemical properties are key factors in the overall forage productivity in this water scarce region. Improving forage yield, WUE, and soil properties under irrigation are very important for food and ecological security in this water-deficient region. Additionally, a suitable irrigation schedule for this region is necessary.MethodsA field experiment was conducted between 2015 and 2018 to evaluate the effects of irrigation on artificial grassland productivity and the changes in soil chemical properties as well as to plan a reliable irrigation schedule for the western Songnen Plain. Eight irrigation treatments were designed, which depended on the three growth stages of alfalfa. The shoot height (SH), the chlorophyll content (SPAD), the dry yield (DM), the ratio of stem to leaves (SLR), the WUE, the changes in the chemical properties of the soil, and precipitation and evaporation were investigated.ResultsThe SH, DM, WUE, and SLR were significantly increased by irrigation (P< 0.01). However, the SPAD resulting from irrigation was not significantly higher than the SPAD of CK (no irrigation) (P< 0.05). In addition, the soil chemical properties at the depth of 0–100 cm were significantly decreased by irrigationP(0.05). For example, the soil electrical conductivity, sodium absorption ratio, and total alkalization were reduced 182–345 μS cm−1, 8.95–9.00 (mmolc/L)1/2, and 3.29–4.65 mmolcL−1by different irrigation treatments, respectively. Finally, considering the highest WUE of I5 (irrigation at branch stage) (2.50 kg m−3), relative high DM of I5 (787.00 g m−2), the precipitation, the evaporation, the water resources, and the changes of the soil’s chemical properties, 236.50 mm of irrigation water was recommended at the branching stage of alfalfa for the western Songnen Plain, Northeast China.

Published: July 2019

Agricultural intensification has resulted in severe soil nutrient depletion in Africa. Alternative agricultural practices have been promoted to restore and sustain soil fertility. Use of mineral fertilizer alongside different cropping systems has been particularly promising. This study was conducted in the Guinea savannah zone of Ghana during the 2015 and 2016 cropping season (July to November) to assess the performance of soybean and maize in a rotation system. In season one, using randomized complete block design the treatments were, soybean (without treatment), inoculated soybean, soybean with phosphorus application, inoculated soybean with phosphorus application and maize. During the second season, the first season experimental plots served as main-plots and divided into four sub-plots on which maize planted and treated with four nitrogen rates in a split plot design. The results show that soybean production leads to significant increase in residual soil nitrogen content of about 16kg/ha to 55kg/ha, which is about 28 folds higher than that observed in maize fields. The level of Residual N was enhanced with inoculation. Phosphorus application during the first season of maize cultivation led to increases in residual P levels, which had a positive impact on yield of soybean in the second season. Grain yield of maize that followed soybean in a rotation system performed better than maize that followed maize at various fertilizer rates. This shows that, the residual N and P helps maize and soybean respectively in a rotation system which makes it highly economical.

AbstractWe report the case of a patient suffering from cortical blindness following bilateral occipital stroke, who recovered normal vision in his right visual field following injection of the local anesthetic mepivacaïne. The effect was transient but reproducible, allowing the patient to lead a normal life. Effect duration increased after adjunction of paroxetine. We provide anatomical and functional brain imaging correlates of this improvement, showing particularly how functional connectivity is restored between intact perilesional cortex and distant brain regions. This serendipitous finding may potentially benefit patients suffering from visual but also nonvisual handicap following brain lesions.
Design of 2‐hydroxyethyl methacrylate‐functional macromonomer dispersants by semi‐batch cobalt chain transfer polymerization
Authors: Van Steenberge Paul H. M. , Hutchinson Robin A. 
Published: July 2019

AbstractAcrylic resins for automotive coatings are produced in nonaqueous dispersions (NAD) of nanometer size. These must be sterically stabilized by oligomeric dispersants, which are complex reactive oligomers possessing vinyl and hydroxyl functionalities, controlling the size of the nanocolloid. Hence, we have developed a kinetic Monte Carlo (kMC) model to improve the molecular structure of 2‐hydroxyethyl methacrylate‐functionalized poly (butyl methacrylate) (pBMA) dispersants of ca. 6,000 g/mol produced via semi‐batch cobalt chain transfer polymerization (CCTP). The kMC‐predicted degree of functionalization is benchmarked against a novel analytic expression suitable for oligomers. Stepwise adjustment of the semi‐batch feed program illustrates the successive improvement in molecular structure of the dispersant product, finally arriving at a functionalization degree close to the theoretical maximum for CCTP.

AbstractAmerican Indian (AI) communities have high levels of stress and trauma and are disproportionately affected by numerous preventable diseases. Here, we describe an academic–community partnership based on a collaboration between Blackfeet Community College students and faculty in Psychology and Immunology at Montana State University (MSU). The collaboration, which has spanned over 5 years, was sparked by community interest in the relationship between stress and disease on the Blackfeet reservation. Specifically, community members wanted to understand how the experience of psychological stress and trauma may affect disease risk in their community and identify factors that promote resilience. In doing so, they hoped to identify pathways through which health could be improved for individual community members. Here, we discuss all stages of the collaborative process, including development of measures and methods and themes of research projects, challenges for community members and non‐indigenous collaborators, future directions for research, and the lessons learned. Finally, we note the ways in which this partnership and experience has advanced the science of community engagement in tribal communities, with the hope that our experiences will positively affect future collaborations between indigenous community members and non‐indigenous scientists.

BackgroundAs the management of ventral skull‐base pathology has transitioned from open to endonasal treatment, there has been an increased focus on the prevention and endoscopic endonasal management of internal carotid artery (ICA) and major vascular injury. The use of adenosine to induce transient hypotension or flow arrest has been previously described during intracranial aneurysm surgery; however, there have been no reports of the technique being used during endonasal skull‐base surgery to achieve hemostasis following major vascular injury.MethodsCase report (n = 1) and literature review.ResultsA 25‐year‐old female underwent attempted endoscopic endonasal resection of an advanced right‐sided chondrosarcoma. During resection of the tumor, brisk arterial bleeding was encountered consistent with focal injury to the right cavernous ICA. Stable vascular hemostasis could not be achieved with tamponade. An intravenous bolus dose of adenosine was administered to induce a transient decrease in systemic blood pressure and facilitate placement of the muscle patch over the direct site of vascular injury. The patient subsequently underwent endovascular deconstruction of the right ICA.ConclusionThis is the first reported use of adenosine to induce transient hypotension for a major vascular injury sustained during endonasal skull‐base surgery. Based on well‐established safety data from neurosurgical application, adenosine has the potential to be used as a safe and effective adjunctive technique in similar endonasal circumstances and may represent an additional tool in the armamentarium of the skull‐base surgeon. Surgeons should consider having adenosine available when a risk of ICA injury is anticipated.

AbstractThis study aimed to verify whether the fatty acid profiles of mid‐oleic genotypes grown in the tropical region of Brazil fit the Codex Alimentarius and to examine the possibility of using traditional inbred lines to produce high‐oleic hybrids. For this purpose, we assessed the fatty acid profile of six mid‐oleic hybrids grown in environments with different minimum temperatures during oil formation in the achenes. The tests were conducted between 2015 and 2017 in an experimentally randomized complete block design with four replications. The oleic, linoleic, palmitic, and stearic acid contents were determined using gas chromatography. The mid‐oleic hybrids presented varying levels of fatty acids, with oleic acid ranging between 43.6% and 84.6%, linoleic acid between 8.5% and 45.6%, palmitic acid between 3.9% and 5.7%, and stearic acid between 2.2% and 6.2%. Some of the fatty acid values were outside the ranges established by the CODEX STAN 210‐1999 and were characteristic of high‐oleic type sunflowers. This finding shows that we can take advantage of the potential of combining traditional inbred lines to produce high‐oleic hybrids for faster and more economical breeding programs in these environments.
Catalytic hydrodeoxygenation of bio‐oil model compound for production of fuel grade oil

Published: July 2019

AbstractBio‐oil, a promising renewable fuel candidate obtained from the hydrothermal liquefaction/pyrolysis of agricultural waste, contains significant amount of oxygen in the form of oxygenated compounds such as aldehydes, ketones, aliphatic/aromatic acids, alcohols, and ethers. This prevents it from being used directly as a fuel. Technologies that can lower the oxygen content of bio‐oil are desired. The present work was driven towards the deoxygenation of bio‐oil. To understand the mechanism of deoxygenation, guaiacol was selected as a model compound. The deoxygenating ability of acid site (support) and hydrogenation ability of metal were leveraged in this work. Highly acidic mixed oxide support such as ZrO2–Al2O3 was used to synthesize a bimetal catalyst Ni–Mo/ZrO2–Al2O3, and the said catalyst was used for deoxygenation of bio‐oil/model compound in tetralin as hydrogen donor solvent. The effects of reaction time, temperature, and hydrogen pressure on the conversion were examined. Results showed that 100% guaiacol conversion was obtained with 45.3% phenol and 11.1% cyclohexane yield at 330°C and 30‐bar H2 pressure and reaction time of 10 hr.
