Towards practical dynamic induction control of wind farms:
analysis of optimally controlled wind-farm boundary layers and
sinusoidal induction control of first-row turbines
Authors: Munters Wim , Meyers Johan
Published: February 2018

Abstract. Wake interactions between wind turbines in wind farms lead to reduced energy extraction in downstream rows. In recent work, optimization and large-eddy simulation were combined with optimal dynamic induction control of wind farms to study the mitigation of these effects, showing potential power gains of up to 20 % (Munters & Meyers 2017 Phil Trans R Soc A 375, 20160100, doi:10.1098/rsta.2016.0100). However, the computational cost associated with these optimal control simulations impedes practical implementation of this approach. Furthermore, the resulting control signals optimally react to the specific instantaneous turbulent flow realizations in the simulations, so that they cannot be simply used in general. The current work focuses on the detailed analysis of the optimization results of Munters & Meyers, with the aim to identify simplified control strategies that mimic the optimal control results and can be used in practice. The analysis shows that wind-farm controls are optimized in a parabolic manner with little upstream propagation of information. Moreover, turbines can be classified into first-row, intermediate-row, and last-row turbines based on their optimal control dynamics. At the moment, the control mechanisms for intermediate-row turbines remain unclear, but for first-row turbines we find that the optimal controls increase wake mixing by periodic shedding of vortex rings. This behavior can be mimicked with a simple sinusoidal thrust control strategy for first-row turbines, resulting in robust power gains for turbines in the entrance region of the farm.
El ensayismo crítico y la transnacionalización del latinoamericanismo en el Cono Sur (1990-2000)
Authors: Patiño Roxana
Published: February 2018

Este artículo se enfoca en el estudio del debate teórico sobre el latinoamericanismo crítico transnacionalizado a finales del siglo XX en su intersección con el ensayismo crítico del Cono Sur, en particular, en la forma en que éste se transforma en un dispositivo discursivo para establecer una diferencia respecto de los usos y la razón crítica de los discursos académicos sobre la literatura latinoamericana en la primera fase de la globalización. Especial énfasis se hace en el ensayismo de las revistas Punto de Vista (Argentina) y Revista de Crítica Cultural (Chile), y de sus dos directoras, Beatriz Sarlo y Nelly Richard, respectivamente.
La construcción somocista de la figura de Rubén Darío
Authors: Moro Diana
Published: February 2018

Este artículo describe y analiza cómo el régimen de Anastasio Somoza García toma la figura y la obra de Rubén Darío con una intencionalidad política explícita para su propia legitimación. A partir del desarrollo de los homenajes celebrados en el año 1941, a 25 años de muerte de Darío y de la publicación de fragmentos de La vida de Rubén Darío escrita por él mismo y de El viaje a Nicaragua, se percibe la manipulación de la obra del poeta y la continuación de una disputa que comienza en el momento mismo de su muerte.
Brasil y la cuestión americana (Rodó por Sérgio Buarque de Holanda, Gilberto Freyre y João Pinto da Silva, 1920-1926)
Authors: Rocca Pablo
Published: February 2018

Brasil fue un espacio semivacío en la reflexión americana de Rodó, casi un enigma. Sin embargo, en distintos puntos del país-continente, jóvenes que con el tiempo fueron intelectuales decisivos vieron en la obra de Rodó un obstáculo y un desafío. Algunas notas tempranas de los muy jóvenes Sérgio Buarque de Holanda y de Gilberto Freyre revelan sus preocupaciones por las ideas de Rodó en relación a sus propias búsquedas, mientras para el crítico más destacado del Novecientos, José Veríssimo, Ariel se había convertido ya a comienzos de siglo en una posibilidad de diálogo americano y hasta de síntesis de sus ideales profundos, el gaúcho João Pinto da Silva adoptó las ideas del montevideano casi como una guía. Este artículo revisa qué pudo llevar, sobre todo entre 1920 y 1926, a tales escrutinios y posiciones, y cuáles fueron algunos de sus efectos en la escritura y el pensamiento que enlaza Brasil con Hispanoamérica, territorios físicos, lingüísticos y simbólicos de siempre compleja articulación.
Ilusión de presencia y mirada en dos poemas sobre arte de Álvaro Mutis
Authors: Giraldo Efrén
Published: February 2018

Los estudios sobre la écfrasis poética han puesto de presente la naturaleza elusiva de su representación. El propósito de este artículo es confirmar esta hipótesis, analizando recursos de orden retórico, hermenéutico y crítico en dos poemas del poeta colombiano Álvaro Mutis. Para ello se rastrea la presencia del sociolecto del arte en los poemas, se examina la superposición de lo crítico y valorativo sobre lo descriptivo y se analizan los contextos estéticos que enmarcan los dos cuadros a los que aluden los poemas.
Un viaje interminable hacia el pasado. El testigo de Juan Villoro
Authors: Perilli Carmen
Published: February 2018

Juan Villoro transforma escritura y vida del poeta Ramón López Velarde en la trama de una metaficción que reflexiona sobre la literatura y la cultura nacional mexicana. El personaje Julio Valdivieso, que llega a México a seguir los pasos del escritor, acaba encontrándose consigo mismo en la medida en que acepta que el futuro es un viaje hacia el pasado. Villoro, en la mejor tradición latinoamericana, rescata la provincia como metáfora de la nación. Julio, una suerte de Juan Preciado, se interna en el paisaje familiar para aceptar la destrucción de los archivos y la ineptitud de los testigos. Encuentra su destino personal en un desierto donde sólo habitan las vidas desechadas y se escucha las voces de los muertos.
El testimonio y la experiencia de la muerte. Raúl González Tuñón
Authors: Straccali Eugenia
Published: February 2018

La mirada del que testimonia no sólo es prueba, evidencia, también se impone como lugar simbólico desde el cual se narra una experiencia única e irrepetible. Raúl González Tuñón configura un sujeto ficcional y testimonial, pero no se inscribe como autoridad que presenta la verdad de lo acontecido, sino como sujeto garante de una experiencia inenarrable, la de la muerte. Ese sujeto ficcional, poético, habla de la muerte y recupera esta experiencia de lo real como vivencia, rescata lo impresentable, estetiza, da a conocer zonas veladas de lo real. El tipo de sujeto que rubrica un testimonio no se verá implicado solo como testigo que ve y da fe de lo visto, sino que se construye desde una posición de sujeto partícipe que postula una versión posible de lo ocurrido y además cuestiona otras versiones: todo lo testimoniado depende de una enunciación que es siempre postura y selección.

The scarcity of good quality water is a limiting factor for irrigated agriculture, especially in arid and semiarid regions, where water sources generally contain high concentrations of ions. In such conditions, it is essential to cultivate genotypes with economic potential and tolerance to salinity. Considering the importance of citrus and the need to identify genetic materials that adapt to saline stress, this study evaluates the salinity tolerance of 10 genotypes with rootstock potential. For the irrigation water, five levels of electrical conductivity (ECw: 0.8, 1.6, 2.4, 3.2 and 4.0 dS/m at 25 °C) were used in a randomized block design with three replications, and seed germination and growth variables, as well as physiological plant parameters, were evaluated. The germination rate of the hybrid TSKC × CTARG – 019 was the best under salt conditions, as it was the genotype with the highest tolerance to salinity in the germination stage. Salinity reduced the growth of the citrus genotypes, with the possibility of using water with EC of up to 1.6 dS/m in the rootstock formation stage. Salt stress affected the photosynthetic rate of the genotypes ‘San Diego’ citrandarin and TSKC × CTSW – 018 by reducing the stomatal conductance, restricting the diffusion of CO2 into the substomatal camera. The genotypes TSKC × CTARG – 019, TSKC × CTTR – 012 and TSKC × TRBK – 007 have the greatest potential for growth and photosynthetic apparatus efficiency when subjected to salinity.

Evaluation the performance of the algorithms and the method that is used to implement it play a major role in the assessment of the performance of many applications and it help the researchers to decide which algorithm to use and which method to implement it, it also give indicate of the performance of the hardware that the algorithm is tested over. In this paper we evaluate the performance of solving linear equation application over supercomputer which was implemented and using Message Passing interface (MPI) library. The sequential and multithreaded algorithm for solving linear equations has been experimented too and the results has been recorded, the speedup and efficiency of the algorithm has been calculated and the results showed that the parallel algorithm outperforms other methods with the large size matrix of 8192 * 8192 over the number of processors of 64. For large input size, the results also showed that there is a noticeable decrease in running time as the number of processors increase. But in case of multithreaded the results showed that as the matrix size increase the time required for running the algorithm is rapidly increasing although the number of threads increased. This indicates that the parallel performance over for large matrix input size is better and outperforms other methods.

El tópico de la cualidad y el individualismo en la publicidad: “El efecto J&B”
Authors: Cobo Durán Sergio , Hernández de Santaolalla Aguilar Víctor
Published: February 2018

La publicidad recurre a la retórica para la construcción de sus mensajes, y utiliza los lugares comunes o “topoi” para facilitar la comprensión de su público. De todos los lugares comunes, el tópico de la cualidad es uno de los más utilizados. Así pues, la publicidad es un discurso marcadamente individualista condicionado por la situación política y socioeconómica en la que está inmerso, lo que ayuda a entender la preeminencia del tópico de la cualidad frente a otros existentes.

Published: February 2018

Las características físicas de los modelos masculinos publicitarios es un aspecto no verbal del mensaje que suele ser utilizado en los procesos creativos de determinados anuncios, para atraer y dotar al producto/marca anunciado de atributos que objetivamente no posee. La vigorexia es una reciente psicopatología que provoca, en quienes la sufren, alteraciones en su percepción somática con cuadros depresivos y obsesivos. Por su influencia y repercusión social, la publicidad de determinados productos y los modelos allí representados, parecen erigirse como uno de los factores del macroentorno social que influye en el origen y desarrollo de esta nueva patología.

Konflikt zbrojny polsko-czechosłowacki o Śląsk Cieszyński (styczeń–luty 1919) w polskojęzycznej prasie regionu
Authors: Wnętrzak Grzegorz
Published: February 2018

The article shows the role of the Polish press in the military conflict between
Poland and Czechoslovakia about Cieszyn Silesia that took place in January and
February 1919. The press at that time was of key significance due to many
reasons. One of them was that local politicians were often editors and journalists
of these magazines. The author analyses the articles of particular press titles, not
only those that were pro-Polish, but he also takes into account the Pro-Czechoslovak
ones, associated with the Józef Kożdoń’s Movement. The author shows that
the press had both an informational and propagandist function. He also points
out the similarities and differences in the propagandist activity in the pro-Polish
press, determined by the political affiliation of the particular magazine. The
author presents the methods of the press propaganda, so that in specific local
circles they played a role of the pro-Polish or pro-Czechoslovak factor.
The Exhibition-Organising Activity of the Committee for Cultural Cooperation with Foreign Countries (1950–1956)
Based on the Example of Selected Exhibitions at the Zachęta Central Bureau of Art Exhibitions
Authors: Zychowicz Karolina
Published: February 2018

The documentation of the Committee for Cultural Cooperation with Foreign Countries,
which was an offi cial agency active in the years 1950–1956, is currently deposited at the
Central Archives of Modern Records in Warsaw and constitutes an invaluable source for
any Polish scholar interested in the history of exhibitions. It contains large amounts of
interesting data which make it possible to ascertain the character of Polish exhibitionorganising
activity in the fi rst half of the 1950s. In the six years of its existence the Committee
organised ca. one hundred exhibitions. The essay concerns exhibitions hosted in
the main building of the Central Bureau of Art Exhibitions, i.e. the Zachęta. Foreign exhibitions
prepared by the Committee were intended to justify the state’s cultural strategy
based on promoting the aesthetics of Socialist Realism, which programmatically referred
to 19th-century Realism and its historical traditions. Exhibitions of art produced in the
countries of the Eastern bloc presented the local version of Social Realism plus 19th-century
painting that could be described as “Critical Realism”. Bringing to Poland exhibitions of
folk art from the “brotherly” countries of the Eastern bloc was an important element of
the Committee’s policy, as in the years 1949–1956 attempts were made to use folk art in
the process of remodelling the country in the Socialist spirit. The Committee for Cultural
Cooperation with Foreign Countries was established in 1950 in order to centralise, expand
and politicise artistic exchange. On the whole, however, the idea to centralise all of the
cultural exchange with foreign countries turned out to be a utopia. In 1955, just as the
so-called thaw was beginning, the Ministry of Culture and Art offered the proposal to
decentralise the exchange and to dissolve the Committee.

What happened when the poster, originally an advertising medium, became an object of
appreciation in the museums of Communist Poland? What criteria did it have to comply
with in order to be accepted into a temple of art, a museum? The article analyses poster
exhibitions organised at the Zachęta Central Bureau of Art Exhibitions in the 1950s. During
this period, the interest of museum curators, critics and art historians in this medium
must be envisioned as always being underpinned by political and propagandist interests;
the transition of the poster to the status of a work of art is analysed here in this double,
i.e. cultural and political, perspective.
Socio-pedagogical knowledge expertise across the social care sectors in Northern Europe
Authors: Dychawy Rosner Irena
Published: February 2018

A major challenge in contemporary welfare societies is the delivery of services affirming people’s expectations for their life standard, health and social care services. For decades, there has been a search to understand new ways of conceptualising social pedagogy as a field of practice, as a theory, and as a programme design and implementation. Despite the growing body of literature on social pedagogy, to date, little has been written on the subject of the unique complexities of social pedagogy knowledge expertise when bridging the supporting relationships between an individual and the social dimensions in his/her world.

Based on research conducted in Northern Europe, particularly focusing on Denmark and Sweden, the aim of this special issue of International Journal of Papers of Social Pedagogy (PSP) on Contemporary Issues in Social Pedagogy in Northern Europe is to convey the central importance of social pedagogy for the study of vitality and diversity behind social pedagogy thought. The presented research projects in this special issue are, in their foundation, associated with a constructivist approach that views the body of knowledge development as an active and cooperative process of knowledge construction and its application in social pedagogy discipline. This article intends to provide a general perspective concerning the presence of various knowledge forms according to the search for, and implementation of, thinking and acting in a social pedagogy inspired way, and working under various conditions.
Is Nature Natural? And Other Linguistic Conundrums
Authors: Utsler David ,   International Association for Environmental Philosophy
Published: February 2018

One of Scott Cameron’s most recent contributions to environmental hermeneutics (a field in which he was a founding scholar) was to defend the concept of nature against those who would argue that it should be abandoned in order to stave off the ecological destruction. Rather than jettison nature as an outdated and unhelpful construct, Cameron argued for its redemption based on Gadamer’s hermeneutical insights into language. In this article, I will look at Cameron’s arguments against Steven Vogel as well as particular points made against nature as a concept recently articulated by Slavoj Žižek and Timothy Morton. I will follow these arguments through, demonstrating that while the arguments can be accepted and are, indeed, accurate, the conclusion that the concept of nature be abandoned need not and should not be conceded. Finally, I will return to Cameron’s hermeneutic defense of a concept of nature and expand further on his insights and arguments. With Cameron, I conclude that the concept of nature can be redeemed. Extending Cameron’s line of reasoning, I argue that this aim is accomplished by refiguring the concept of nature with the insights offered by philosophical hermeneutics.
OBTAINING GRANULATED ACTIVE CARBON FROM WASTES OF VEGETABLE RAW MATERIALS
Authors: Farberova Еlena A. , Tingaeva Elena A. , Chuchalina Anna D. , Kobeleva Asiya R. , Maximov Andrei S.
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.

SOLVATION CONTRIBUTIONS OF PYRIDINE FUNCTIONAL GROUPS IN TRANSFER ENTHALPY OF AMINE FROM METHANOL TO ACETONITRILE, DIMETHYL SULFOXIDE AND DIMETHYLFORMAMIDE
Authors: Kuz’mina Irina A. , Volkova Mariya A. , Kuz’mina Kseniya I. , Sharnin Valentin A. , Belova Natalya V.
Published: February 2018

Quantum-chemical calculations of the energy and structure of pyridine molecule (Py) in the free state, methanol (MeOH), acetonitrile (AN), dimethyl sulfoxide (DMSO) and dimethylformamide (DMF) have been performed using the density functional theory (DFT) at the B3LYP with the 6-31G basic set supplemented by polarization and diffuse functions and within the model of the self-consistent reactive field (PCM). It was found that the transfer of the pyridine molecule from the free state to the MeOH, AN, DMF and DMSO media leads to: an increase in bond distances only between nitrogen and carbon atoms of amine; significant changes in the charges on the carbon atoms associated with the reaction center (the growth of positive charges varies in the series: DMF = DMSO < MeOH = AN); an increase in the positive charge on hydrogen atoms, which varies in the series: MeOH = AN < DMF = DMSO. A comparative analysis of the results from quantum chemical calculations was carried out with data on transfer enthalpies of amine from MeOH to AN, DMF and DMSO (ΔtrH°(Py)MeOH → solv) which were obtained by calorimetric method. It was found that the resolvation of the nitrogen atom gives the major contribution to the change in the solvate state of pyridine when the composition of the solvent MeOH → DMF and MeOH → AN changes. In case of transfer of Py from MeOH to DMSO, contributions from the resolvation of the nitrogen atom and the hydrocarbon radical to the overall energy of the resolvation of molecule are approximately the same.Forcitation:Kuz’mina I.A., Volkova M.A., Kuz’mina K.I., Belova N.V., Sharnin V.A.

EXPERIMENT-CALCULATING STUDY OF THERMAL DECOMPOSITION OF NATURAL DOLOMITES IN FLUIDIZED BED
Authors: Mitrofanov Andrey V. , Mizonov Vadim E. , Vasilevich Sergey V. , Malko Mikhail V.
Published: February 2018

The aim of the present investigation is to develop a model to describe the hydrodynamics, heat and mass transfers during thermal decomposition of dolomite particles in a fluidized bed. The decomposition of dolomite samples with mass from the range of 0.5-1.4 g under heat treatment has been studied in a laboratory furnace. The dissociation rate constants for magnesium and calcium components of dolomite have been determined in form of the Arrhenius equation. The obtained kinetic equations have been used in the model of fluidized bed. The model is based on the Markov chain approach and allows simulating the heat and mass transfers in fluidized bed. It contains two parallel chains of cells: one for the dolomite particles and another one for the fluidizing gas. The homologic cells of the chains can exchange heat and mass while the longitudinal the media is described by the matrices of transition probabilities. The cells for particles contain heat sources caused by the ongoing reactions. The transition matrices are associated with current physical properties of substances involved that makes the proposed model non-linear. A good agreement with the experimental data has been achieved in simulating of gas supplying, heating and decomposition of an individual particle. The modeling of the heat treatment of dolomite particles with mass 350 g under the action of fluidization was performed. One of the main features of the process influencing the bed hydrodynamics is the bed expansion with time. It occurs due to the dolomite particles settling velocity decrease during their thermal treatment. The calculating results have shown space and time non-homogeneity of the dissociation rate. The proposed mathematical model can be used as the scientific basis for operating control and design of fluidized bed reactors.Forcitation:Mitrofanov A.V., Mizonov V.E., Vasilevich S.V., Malko M.V.

La méthode des entretiens de groupe a été employée lors de rencontres avec sept directions d’établissement au Québec et 17, au Nouveau-Brunswick. Une analyse de contenu a montré que, dans l’ensemble, les indicateurs des composantesConnaissances,AttitudesetHabiletésduModèle initialétaient bien adaptés au contexte des deux provinces. Cependant, six indicateurs ont été ajoutés afin de permettre une meilleure adaptation duModèle initialau contexte des dites provinces. Cette recherche permet donc de présenter unModèle adaptéde la compétence interculturelle des directions d’établissement scolaire de langue française au Québec et au Nouveau-Brunswick qui peut servir d’outil d’(auto)formation.
L’impact d’une initiative de formation internationale sur la notion de leadership et les pratiques professionnelles des directions d’école1
Authors: Rocque Jules
Published: February 2018

Cette recherche a pour objectif de cerner l’impact d’une initiative de formation continue internationale sur la notion de leadership de 23 directions d’école haïtiennes de même que son incidence sur le développement de leurs pratiques professionnelles. Les données obtenues par un questionnaire auprès des directions d’école et les observations sur le terrain ont permis de conclure que l’initiative de formation, fondée sur une approche collaborative, a eu un impact sur la notion de leadership allant d’une vision bureaucratique à collaborative tout en contribuant au développement des capacités locales. Nous estimons qu’un retour sur le terrain nous permettra de mieux saisir la portée de la formation sur le développement des pratiques professionnelles des directions d’école, et ce faisant, de leur rôle en tant qu’agents de changement au sein du système scolaire.
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.

Published: February 2018

Afin de faciliter la participation sociale des enfants ayant un trouble primaire de langage (TPL), il est important de connaître les obstacles ou les facilitateurs environnementaux dans les milieux de vie de l’enfant. Le but de cette étude exploratoire est d’identifier ces facteurs pour des élèves du primaire ayant un TPL. Vingt-six parents d’enfants de 5 à 13 ans ayant un TPL et onze intervenantes scolaires ont rempli le questionnaire Évaluation des facteurs environnementaux influençant la participation sociale des élèves du primaire présentant un trouble de la communication (Croteau et al., 2015b). Plusieurs facteurs des milieux scolaires et familiaux sont perçus comme étant des facilitateurs à la réalisation des habitudes de vie, tandis que des obstacles sont mentionnés à l’école, dans la famille et dans la communauté. Des cibles d’actions sont suggérées au plan de la disponibilité des services, de la réduction du bruit et de l’attitude des pairs.
Microplastics in the environment: Much ado about nothing? A debate
Authors: Backhaus Thomas , Wagner Martin
Published: February 2018

This manuscript documents a debate between the two authors on the issue of microplastics in the environment. It was sparked by a recent viewpoint article published by G. A. Burton in Environmental Science and Technology (http://doi.org/10.1021/acs.est.7b05463) and started as a Twitter debate. To expand, we decided to continue our conversation publishing 1000 word texts on peerJ and responding to each other in two-week intervals.

Currently, the text contains the following:

1) An introduction, which sets the scene for the article

2) Martin' kick-off statement dated Feb. 27, 2018

Thomas will then follow up with his comment & rebuttal two weeks later.

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

Background

Epidendreae 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.

Methods

A series of late floral stages were sampled and fixed for examination under scanning electron microscope.

Results

Anther 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.

Discussion

Our 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.

O trabalho livre e associado é rememorado/experienciado em diversas comunidades tradicionais espalhadas pelo Brasil, bem como no estado do Mato Grosso. Tratam-se de exemplos de formas autogestionárias, coletivas, solidárias e cooperativas de produção da existência em que trabalhadoras e trabalhadores buscam resistir ao individualismo, ao mercado, à competição e à maximização dos lucros, demonstrando que possuem uma específica concepção de mundo e de trabalho. Assim, a partir do materialismo histórico dialético, o presente escrito tem como objetivo refletir acerca de experiências de existências e resistências frente ao capital de comunidades tradicionais localizadas no Mato Grosso. 
O tempo longo e a obra: exigências da história
Authors: Pereira Maria de Fátima Rodrigues
Published: February 2018

Resenha-se o livro de Mauri Iasi, lançado neste ano de 2017 pela Instituto Caio Prado Jr., intitulado Política, Estado e ideologia 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.

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.
