Figures disparues, figures de la disparition dans les œuvres de Luis Caballero et d’Oscar Muñoz
Authors: Bernard-Nouraud Paul
Published: May 2017

En portant attention à l’œuvre de Luis Caballero d’abord, à celle d’Oscar Muñoz ensuite, cet article entend mettre en évidence les processus de figuration des disparus dans l’art contemporain colombien du tournant des années 1990 jusqu’à aujourd’hui. Les corps que figure Caballero à cette période montrent en effet une tendance intensive là où ils avaient d’abord semblé s’étendre au-delà des limites du tableau ; tendance intensive qui informe en revanche tout l’œuvre de Muñoz. Cette forme est voisine du paradigme indiciaire qu’a énoncé Rosalind Krauss à propos de l’art états-unien des années 1970 et que María Margareta Malagón-Kurka a transposé au contexte colombien cité, à ceci près qu’à partir des corps qu’il figure il produit des traces davantage que des indices, dans la mesure où leur figuration même est menacée de disparition.
Erotismo y transgresión en la obra “El delirio de las monjas muertas” de Juan Antonio Roda
Authors: Miklos Aline
Published: May 2017

Este artículo analiza la obra “El delirio de las monjas muertas” (1972-74), de Juan Antonio Roda (Valencia 1921 – Bogotá 2003), constituida por una serie de 12 grabados en aguafuerte, aguatinta y punta seca. A partir de conceptos como erotismo, transgresión, espectro y síntoma visual se indaga sobre el juego de lenguaje presente en el título y los juegos visuales en los cuales predominan las metáforas, las yuxtaposiciones y las superposiciones. Todos estos movimientos son centrales en la obra en cuestión y en la visión del artista sobre la relación entre las monjas y su divinidad. Ellos traducen el mutuo deseo de poseer, de ser poseído y evocan la danza sensual entre los amados. Asimismo, forman el conjunto de herramientas elegidas por el artista para transgredir, es decir, para jugar con los límites de los tiempos, de las formas, de lo sagrado y de lo profano. Así, este artículo pretende contribuir, en particular, a la comprensión de esta obra que ha sido debatida entre los críticos de arte, y, en general, al estudio de la relación entre el arte contemporáneo y el cristianismo.
The 3rd Bienal da Bahia: Transgressive Archives
Authors: Lawrence Adiva
Published: May 2017

This article looks at the means deployed by the 3 Bienal da Bahia (2014) to re-enact the spirit of transgression that defined its previous editions, which took place in the 1960s at a time of political turmoil in Brazil, and questions the ability of artistic events to affect political resistance through the subversion of established codes. The Bienal was conceived as an archive-in-progress, and this article examines the potential of the archive as a transgressive tool. It provides an overview of the structure of the event, from its curatorial project to its actual execution, analysing it in the light of theoretical insights into contemporary exhibition making and archive politics.
Art vidéo, corps, espace public et télévision: les tranchées et les Institutions au Brésil et au Chili des années 1980
Authors: Melo Tálisson
Published: May 2017

Cet article vise à rendre compte des premiers résultats issus d’une période de stage de recherche accomplie au Museo de Arte Contemporáneo de l’Université du Chili (MAC-U.Chile). Je pars d’un groupe de manifestations artistiques qui ont eu lieu dans la rue ou pendant des évènements institutionnels ouverts au public, où la vidéo a été utilisée comme forme d’enregistrement et expérimentation. Je propose une réflexion sur la participation des critiques d’art dans la dynamique d’institutionnalisation de l’art vidéo à Rio de Janeiro, São Paulo et Santiago, à travers la circulation de leurs idées et leur contact avec les artistes. La présente analyse vise à mettre en parallèle les réflexions sur le contexte d’émergence de l’art vidéo au Brésil et au Chili ; ainsi qu’à appréhender la dynamique de transgression et d’institutionnalisation de ce nouveau langage qui émergeait sous la dictature. Le corps, l’espace public et la télévision sont ici les points de connexion entre ces pratiques artistiques.
Seduciendo al mundo con paisajes: las imágenes de El Ecuador en Chicago
Authors: Haro María Beatriz
Published: May 2017

Este artículo explora la representación de paisajes ecuatorianos en El Ecuador en Chicago, libro publicado en conmemoración de la participación de esta nación en la Exposición Universal Colombina de 1893. Este trabajo expande la propuesta de Matthías Leonhardt (2009) sobre las tendencias del paisaje ecuatoriano en el siglo XIX, definiendo dos categorías para entender las complejidades de este género artístico en el Ecuador finisecular. Este artículo propone al paisaje-naturaleza y al paisaje-en-progreso como los dos modelos que reflejan las tensiones políticas del Ecuador, pensando en cómo la representación de la naturaleza industrializada y “moderna” de la Costa fue una respuesta a los paisajes sublimes e idealizados de la Sierra.
The Power of Interpretation (or How MoMA explained Guernica to its audience)
Authors: Giunta Andrea
Published: May 2017

In 1947 the publication in English of the book of Juan Larrea, Guernica. Pablo Picasso, produced a great bewilderment in Alfred Barr, who was in charge of the collections of the Museum of Modern Art, New York. The interpretation of the Spanish writer radically contradicted what Barr believed correct, based on the artist’s words. In order to establish the final interpretation of the painting, Barr organized a symposium at MoMA. This essay analyzes the debate that took place through the minutes of the conference and the correspondence and interprets the reasons why it was so important to establish the meaning of the picture.
Notas sobre ’La Cumparsita’. Su recepción en Francia entre 1920 y 1950
Authors: Vidal Edgard
Published: May 2017

La Cumparsita, considerada en el mundo entero el himno de los tangos, festeja su centenario. ¿Pero cómo fue recibida en Europa, a principios del siglo XX y cómo se constituye su suceso francés? ¿Cuáles son en su trayectoria las versiones y agrupaciones mas citadas entre los años 1920 y 1950? El estudio de los diarios y revista de la época nos pareció la mejor manera de estudiar la recepción de éste tango en Paris. Esta nota se propone analizar la trayectoria del “tango de los tangos” a partir de unos documentos muy poco explotados hasta ahora : los carnets de la TSF.
Panser l'erreur à l'école
Authors: Reuter Yves
Published: May 2017

Le terme d'erreur est massivement présent dans les discours sur la dégradation de l'école et la baisse de niveau des élèves. Pourtant, à y regarder de près, cette notion s’avère particulièrement floue et les modes de traitement classiques, fort limités mais encore dominants, n’arrivent guère à éradiquer les problèmes.C’est à partir de ce constat que cet ouvrage s’est donné pour but de mieux comprendre ce que cette notion recouvrait ainsi que les raisons de la résistance des erreurs en milieu scolaire.Le concept de dysfonctionnement – articulant une variante et un jugement porté à son propos – a donc été construit permettant de mettre au jour les intérêts potentiels des difficultés des élèves. Les problèmes, appréhendés dans cette perspective, favorisent en effet une meilleure compréhension des démarches des élèves, des fonctionnements de l'enseignement ou encore de la complexité de certains contenus. Ils permettent, complémentairement, de mieux saisir les spécificités des disciplines de recherche qui s'en servent.Cette perspective offre encore comme avantage d’envisager les interventions d’une manière différente en ouvrant la palette des stratégies possibles.
Airway Epithelial Cells Are Crucial Targets of Glucocorticoids in a Mouse Model of Allergic Asthma

Published: May 2017

Although glucocorticoids (GCs) are a mainstay in the clinical management of asthma, the target cells that mediate their therapeutic effects are unknown. Contrary to our expectation, we found that GC receptor (GR) expression in immune cells was dispensable for successful therapy of allergic airway inflammation (AAI) with dexamethasone. Instead, GC treatment was compromised in mice expressing a defective GR in the nonhematopoietic compartment or selectively lacking the GR in airway epithelial cells. Further, we found that an intact GR dimerization interface was a prerequisite for the suppression of AAI and airway hyperresponsiveness by GCs. Our observation that the ability of dexamethasone to modulate gene expression in airway epithelial cells coincided with its potency to resolve AAI supports a crucial role for transcriptional regulation by the GR in this cell type. Taken together, we identified an unknown mode of GC action in the treatment of allergic asthma that might help to develop more specific therapies in the future.
CXCL4 Exposure Potentiates TLR-Driven Polarization of Human Monocyte-Derived Dendritic Cells and Increases Stimulation of T Cells

Published: May 2017

Chemokines have been shown to play immune-modulatory functions unrelated to steering cell migration. CXCL4 is a chemokine abundantly produced by activated platelets and immune cells. Increased levels of circulating CXCL4 are associated with immune-mediated conditions, including systemic sclerosis. Considering the central role of dendritic cells (DCs) in immune activation, in this article we addressed the effect of CXCL4 on the phenotype and function of monocyte-derived DCs (moDCs). To this end, we compared innate and adaptive immune responses of moDCs with those that were differentiated in the presence of CXCL4. Already prior to TLR- or Ag-specific stimulation, CXCL4-moDCs displayed a more matured phenotype. We found that CXCL4 exposure can sensitize moDCs for TLR-ligand responsiveness, as illustrated by a dramatic upregulation of CD83, CD86, and MHC class I in response to TLR3 and TLR7/8-agonists. Also, we observed a markedly increased secretion of IL-12 and TNF-α by CXCL4-moDCs exclusively upon stimulation with polyinosinic-polycytidylic acid, R848, and CL075 ligands. Next, we analyzed the effect of CXCL4 in modulating DC-mediated T cell activation. CXCL4-moDCs strongly potentiated proliferation of autologous CD4+ T cells and CD8+ T cells and production of IFN-γ and IL-4, in an Ag-independent manner. Although the internalization of Ag was comparable to that of moDCs, Ag processing by CXCL4-moDCs was impaired. Yet, these cells were more potent at stimulating Ag-specific CD8+ T cell responses. Together our data support that increased levels of circulating CXCL4 may contribute to immune dysregulation through the modulation of DC differentiation.

We show that the chainable continua (also called snake-like or arc-like)continua, are precisely the Hausdorff reflections of inverse limits of sequences of finite COTS under maps which are continuous and are separating.
Cofinitely and co-countably projective spaces
Authors: Mendoza Iturralde Pablo , Tkachuk Vladimir V.
Published: May 2017

We show that X is cofinitely projective if and only if it is a finite union of Alexandroff compactatifications of discrete spaces. We also prove that X is co-countably projective if and only if X admits no disjoint infinite family of uncountable cozero sets. It is shown that a paracompact space X is co-countably projective if and only if there exists a finite set B C X such that B C U ϵ τ (X) implies │X\U│ ≤ ω. In case of existence of such a B we will say that X is concentrated around B. We prove that there exists a space Y which is co-countably projective while there is no finite set B C Y around which Y is concentrated. We show that any metrizable co-countably projective space is countable. An important corollary is that every co-countably projective topological group is countable.
Fenestrations induced by perfect tilings
Authors: Arenas F.G. , Puertas M.L.
Published: May 2017

In this paper we study those regular fenestrations (as defined by Kronheimer in [3]) that are obtained from a tiling of a topological space. Under weak conditions we obtain that the canonical grid is also the minimal grid associated to each tiling and we prove that it is a T0-Alexandroff
 semirregular trace space. We also present some examples illustrating how the properties of the grid depend on the properties of the tiling and we pose some questions. Finally we study the topological properties of the grid depending on the properties of the space and the tiling.
The local triangle axiom in topology and domain theory
Authors: Waszkiewicz Pawel
Published: May 2017

We introduce a general notion of distance in weakly separated topological spaces. Our approach differs from existing ones since we do not assume the reflexivity axiom in general. We demonstrate that our partial semimetric spaces provide a common generalization of semimetrics known from Topology and both partial metrics and measurements studied in Quantitative Domain Theory. In the paper, we focus on the local triangle axiom, which is a substitute for the triangle inequality in our distance spaces. We use it to prove a counterpart of the famous Archangelskij Metrization Theorem in the more general context of partial semimetric spaces. Finally, we consider the framework of algebraic domains and employ Lebesgue measurements to obtain a complete characterization of partial metrizability of the Scott topology.
Functorial approach structures
Authors: Brümmer Guillaume C.L. , Sioen Mark
Published: May 2017

We show that there exists at least a proper class of functorial approach structures, i.e., right inverses to the forgetful functor T : AP→ Top (where AP denotes the topological construct of approach spaces and contractions as introduced by R. Lowen). There is however a great difference in nature of these functorial approach structures when compared to the quasi-uniform paradigm which has been extensively studied by the first author: whereas it is well-known from [2] that a large class of epireflective subcategories of Top0 can be “parametrized” using the interaction of functorial quasi-uniformities with the quasi-uniform bicompletion, we show that using functorial approach structures together with the approach bicompletion developed in [10], only Top0 itself can be retrieved in this way.
Di-uniform texture spaces
Authors: Ozcag Selma , Brown Lawrence M.
Published: May 2017

Textures were introduced by the second author as a point-based setting for the study of fuzzy sets, and have since proved to be an appropriate framework for the development of complement-free mathematical concepts. In this paper the authors lay the foundation for a theory of uniformities in a textural context. Analogues are given for both the diagonal and covering approaches to the classical theory of uniform structures, the notion of uniform topology is generalized and an analogue given for the well known result that a topological space is uniformizable if and only if it is completely regular. Finally a textural analogue of the classical interplay between uniformities and families of pseudo-metrics is presented.

Locally convex approach spaces
Authors: Sioen M. , Verwulgen S.
Published: May 2017

We continue the investigation of suitable structures for quantified functional analysis, by looking at the notion of local convexity in the setting of approach vector spaces as introduced in [6]. We prove that the locally convex objects are exactly the ones generated (in the usual approach sense) by collections of seminorms. Furthermore, we construct a quantified version of the projective tensor product and show that the locally convex objects admitting a decent exponential law with respect to it are precisely the seminormed spaces.

Intrastate Dynamics in the Context of Hegemonic Decline: A Case Study of China’s Arms Transfer Regime
Authors: Luo Zhifan
Published: May 2017

The decline of a hegemon can create openings for lesser powers to expand their influence in the world-system. Is this what China is currently attempting to do? This paper contributes to this on-going debate by examining China’s arms transfer activities from a historical perspective. Using data from the Stockholm International Peace Research Institute arms transfer database and the World Military Expenditures and Arms Transfers database, I argue that the Chinese arms transfer regime has evolved through three phases. In Phase One, China used gifts of arms to compete with the Soviet Union and to expand influence among Third World countries. In Phase Two, China used arms exports mainly to assist national developmental projects. Only evidence in Phase Three supports the emergence of a global strategy that attempts to extend China’s economic, political, and possibly military outreach. This paper suggests that though China has not yet become a contender for world hegemony as Arrighi argues (2007), China has formulated a globally-focused agenda which, in the medium-term, could extend its influence in regions where U.S. domination is relatively weak.
Hollow Ecology: Ecological Modernization Theory and the Death of Nature
Authors: Ewing Jeffrey A.
Published: May 2017

The last few decades have seen the rise of ‘ecological modernization theory’ (EMT) as a “green capitalist” tradition extending modernization theory into environmental sociology. This article uses a synthesis of political economy, world-systems theory, and political, economic, and environmental sociology to demonstrate that the EMT presumption of growth and profit as economic priorities (alongside its neglect of core-periphery relations) produces many feedback loops which fatally undermine the viability of EMT’s own political, technological, and social prescriptions, alongside creating problems for the fundamental EMT concept of ‘ecological rationality.’ Furthermore, this article attempts to explain why “green capitalist” approaches to environmental analysis have influence within policy and social science circles despite their inadequacies within environmental sociology. Finally, this article argues that in order to address the ecological challenges of our era, environmental sociology needs to reject “green capitalist” traditions like ‘ecological modernization theory’ which presuppose the desirability and maintenance of profit and growth as economic priorities (and predominantly fail to critique power imbalances between core and non-core nations), and instead return to the development of traditions willing to critique the fundamental traits of the capitalist world-system.
The Caribbean Cruise Ship Business and the Emergence of a Transnational Capitalist Class
Authors: Sprague-Silgado Jeb
Published: May 2017

This paper will provide an overview of the fundamental changes that the cruise ship business has undergone with the emergence of capitalist globalization and in the context of the Caribbean region. Rising profits and investments in tourism during the later decades of the 20th century and into the 21st century have been an important part of the globalizing economy. This has been a consequence of both the major technological and organizational developments of global capitalism, but also, and most importantly, of the global system’s changing social and class relations. The shifting social relations and productive activities that undergird the cruise ship business have meant gains for some involved, most especially, transnational capitalists, and exploitative and contradictory dynamics for many others. Annually millions of tourists from high consuming sectors worldwide partake in brief holiday escapes aboard cruise ship vessels. At the same time, the cruise ship business has become an oligopoly, controlled by a handful of large companies, that has driven many competitors out of business or acquiried them. Labor in the business has become more flexibilized, with low-wage workers (from a variety of nationalities) whose activities are increasingly standardized, monitored and micro-managed. While moving away from indicative development planning (with an eye to national goals), state policymakers in the Caribbean, for their own social reproduction, increasingly promote the interests of transnational capital such as with the cruise ship business. Importantly, labor and environmental protections have been stymied as the cruise ship companies, adept at public relations and skirting regulations, remain largely unaccountable.
Research Note: Measuring the Impacts of Colonialism: A New Data Set for the Countries of Africa and Asia
Authors: Ziltener Patrick , Künzler Daniel , Walter André
Published: May 2017

We present a new dataset with 15 indicators for the political, economic and social impact of colonialism. This dataset and our four indices for the impact of colonialism create for the first time the opportunity to compare directly the levels of colonial transformation for a sample of 83 African and Asian countries. Some of our exploratory findings on the interrelation of the dimensions show that in British colonies political domination was in general less direct and less violent. Plantation colonies experienced more investment in infrastructure and more violence during decolonization. The correlations between indicators for economic distortion (trade policy, trade and FDI concentration) show that the economic re-direction of some colonies towards a more exclusive exchange with the metropole country was an interdependent process. In general, a more intense political domination came along with a higher level of economic transformation. If an area was transformed economically, however, a social transformation was likely to take place too, but these processes should not be confounded. In areas that were politically united for the first time under colonialism, economic distortion and social transformation were more profound.

RESUMO: Neste trabalho foi realizado um estudo de vibrações e conforto humano em uma passarela utilizando modelo numérico tridimensional. Foi elaborado um modelo numérico no software SAP2000, no qual foi realizada uma análise de vibrações livres. Os resultados obtidos foram comparados com valores prescritos por normas. O sistema estudado apresentou frequências fundamentais com valores acima dos valores limites mínimos prescritos por normas, indicando que ele apresentaria problemas relacionados ao conforto humano. A interferência do corrimão da passarela não foi considerada na análise de vibrações, sendo que uma eventual modelagem deste elemento poderia contribuir para elevação da rigidez da estrutura e contribuir para uma provável melhora no comportamento dinâmico.

ABSTRACT: In this work was carried out a study of vibrations and human comfort on a footbridge using three - dimensional numerical model. A numerical model was developed in SAP2000 software, in which a free vibrations analysis was performed. The results obtained were compared with values prescribed by standards. The system studied presented fundamental frequencies with values above the minimum limits prescribed by standards, indicating that it would present problems related to human comfort. The interference of the footbridge was not considered in the analysis of vibrations, and a possible modeling of this element could contribute to increase the rigidity of the structure and contribute to a probable improvement in the dynamic behavior.

Published: May 2017

Bruxism is one of the most common occlusal parafunctions. Etiopathogenesis of bruxism is not fully understood, it is now believed that this phenomenon can be caused by many factors. There are scientific proofs that indicate a relationship between bruxism and disorders or systemic diseases including: insomnia, sleep breathing disorders, uncontrolled limbs movements during sleep, reflux disease, neurological disorders and hypertension. The aim of this study is to determine the relationship between bruxism, hypertension and sleep breathing disorders based on selected literature.
EXPECTATIONS OF THE PATIENTS REFERRED TO PHYSICAL AND REHABILITATION MEDICINE DOCTORS
Authors: Cabak Anna
Published: May 2017

Background: Understanding the expectations of patients seems to be an essential complement to medical diagnosis and an aid in ordaining the healing process. The aim of this study was to assess and analyse the expectations of patients who are re ferred to physical and rehabilitation medicine doctors as a result of various musculoskeletal diseases.
Material/Methods: 90 patients were tested, including 34 males and 56 females, ranging in age from 22 to 88 years (mean age 52.5 ± 19.54), who go to see a doctor predominantly because of back pain. As adopted by Juczyński, the questionnaire assessing patients’ expectations “Patients’ Request Form (PRF), was em ploy ed for statistical analysis, the Mann-Whitney U, Kur skala-Wallis and chi-square tests were also used.
Results: It has been shown that primarily all patients await the diagnosis of their disease and then information about further examination and treatment. Expectation of any emotional support was at the lowest rate, though it did increase with age and was higher in women than in men (p <0.05). The majority of respondents express a wish to take advantage of supplementary physiotherapeutic consultations, ones specially targeted for interim aid, especially when the waiting time for any assigned rehabilitation is two-months and longer.
Conclusions: Further research on patients’ expectations towards medical rehabilitation specialists should be conducted, and its results should be taken into account in the treatment process in order to improve the efficiency and quality of medical services as well as the entire, long-lasting therapy process.
VISUAL-VESTIBULAR AND POSTURAL ANALYSIS OF MOTION SICKNESS, PANIC, AND ACROPHOBIA
Authors: Coelho Carlos M. , Silva Janete , Pereira Alfredo F. , Sousa Emanuel , Taephant Nattasuda , Pisitsungkagarn Kullaya , Santos Jorge A.
Published: May 2017

Background: Visual-vestibular and postural interactions can act as cues that trigger motion sickness and can also have a role in some anxiety disorders. We explore a method to detect individual sensitivity to visual-vestibular unusual patterns, which can signal a vulnerability to develop motion sickness and possibly anxiety disorders such as a fear of heights and panic.
Material/Methods: 65 undergraduate students were recruited for the purposes of this study as voluntary participants (44 females); average age 21.65 years (SD=2.84) with normal or corrected to normal vision, without vestibular or postural deficiencies. Panic was assessed with the Albany Panic and Phobia Questionnaire, Motion Sickness with the Motion Sickness Susceptibility Questionnaire and Acrophobia was assessed by means of the Acrophobia Questionnaire. The Sharpened Romberg Test was used to test participant’s postural balance. The Rod and Frame Test (RFT) measures the participant’s ability to align a rod to the vertical within a titled frame providing a measure of error in the perception of verticality by degrees. This test was changed to measure the error offered when a participant’s head was tilted, and to trace the error caused by manipulating the vestibular system input.
Results: The main findings show only motion sickness to be correlated with significant errors while performing a visual-vestibular challenging situation, and fear of heights is the only anxiety disorder connected with postural stability, although all disorders (fear of heights, panic and motion sickness) are correlated between each other in the self-report questionnaires.
Conclusions: All disorders are correlated to each other in the surveys, and might have some common visual-vestibular origin, in theory. The rod and frame test was exclusively correlated with motion sickness whereas the postural stability test only displayed sensibility to acrophobia. Panic disorder was correlated to neither the RFT nor the Romberg. Although this method was initially employed to increase sensibility in order to detect anxiety disorders, it ended up showing its value in the detection of motion sickness.
The Oslo Accords: Their Context, Their Consequences
Authors: Chomsky Noam
Published: May 2017

In September 1993, United States President Bill Clinton presided over a handshake between Israeli Prime Minister Yitzhak Rabin and Palestine Liberation Organization Chairman Yasser Arafat on the White House lawn—capping off a “day of awe,” as the press described it with reverence. The occasion was the announcement of the Declaration of Principles (DOP) for political settlement of the Israel–Palestine conflict, which resulted from secret meetings in Oslo sponsored by the Norwegian government. This chapter examines the nature and significance of the Oslo Accords, and the consequences that flowed from them. It begins by reviewing highlights of the immediate background that set the context for the negotiations. It then turns to the DOP and the consequences of the Oslo process, which extends to the present, adding a few words on lessons that should be learned.
Avaliação dos limites recomendados de pesos de toras manuseadas em atividades de descascamento de madeira.
Authors: Fiedler Nilton Cesar
Published: May 2017

O presente estudo foi realizado em uma empresa florestal no norte do Estado da Bahia com o objetivo de analisar os pesos manuseados por trabalhadores em operações de descascamento de madeira e compará-los com os limites recomendados de pesos estabelecidos pelo Instituto Nacional de Segurança e Saúde Ocupacional dos Estados Unidos (NIOSH). O descascamento era realizado com um descascador acoplado na tomada de força de um trator. O abastecimento da mesa receptora de madeira era feito por dois ajudantes. Um terceiro direcionava as toras para o interior do descascador e um quarto recebia as toras descascadas e as direcionava para o solo. Os dados dos pesos manuseados foram obtidos com uma célula de cargas. As distâncias da carga ao corpo, ângulos, deslocamentos e freqüências foram obtidos por medições diretas e um estudo de tempos. As análises foram feitas de acordo com o método do NIOSH. De acordo com os resultados obtidos, o maior peso manuseado pelos ajudantes de descascamento foi encontrado na alimentação do descascador, correspondendo a uma média de 20,3 kgf de peso por tora empurrada. A alta freqüência de alimentação por minuto inviabilizou a realização da operação dessa forma, levando a um limite recomendado de pesos igual a zero.

Considerando a expressiva área de florestas plantadas com espécies do gênero Eucalyptus e o uso dessa madeira para múltiplos propósitos, sua cultura é de grande importância econômica para o Brasil. O uso de substratos com boas características físico-químicas constituem importante fator para a qualidade das mudas produzidas. Neste sentido, o objetivo do trabalho foi avaliar o desenvolvimento de diferentes doses de vermicomposto em tubetes com capacidade de receber aproximadamente 50 cm3 de substrato. O estudo foi conduzido em casa de vegetação com Eucalyptus grandis, no período de janeiro a abril de 1997. O substrato utilizado para produção das mudas foi o solo coletado no horizonte A (0-20 cm) da Unidade de Mapeamento São Pedro (Argissolo Vermelho-Amarelo) acrescido de diferentes doses de vermicomposto (0; 5,0; 10,0; 15,0 e 20,0 cm3 por tubete). O vermicomposto utilizado foi proveniente de produção de minhocas vermelhas da Califórnia (Eisenia foetida Savigny) valendo-se de esterco de bovino. Após 100 dias de desenvolvimento, observou-se que as mudas de Eucalyptus grandis responderam de maneira distinta às doses aplicadas, não suportando misturas acima 15,0 cm3 (30%) de vermicomposto por tubete.

Este experimento teve como objetivo avaliar a influência do sombreamento no crescimento de mudas de Peltophorum dubium (Canafístula) e Clitoria fairchildiana (Sombreiro), espécies utilizadas no reflorestamento de encostas do município do Rio de Janeiro. As sementes foram colhidas em diversas matrizes e semeadas em sacos plásticos. As porcentagens de sombreamento testadas foram: 0% (sol pleno), 30%, 50% e 75%. A instalação do experimento iniciou-se um mês após a semeadura. O parâmetro altura foi analisado aos 30, 60, 90, 120 e 150 dias após a semeadura. O peso da matéria seca da raiz foi analisado aos 150 dias. Os resultados demostraram que as espécies estudadas apresentam diferentes respostas  para os parâmetros analisados. Para o plantio imediato recomenda-se a produção de mudas de Sombreiro sob o sombreamento de 30% e de Canafístula, sob sol pleno, 30% ou 75% de sombra. Na produção de mudas para estocagem, seria indicado para o Sombreiro, a produção a sol  pleno e para Canafístula, as mudas poderiam ser mantidas sob 50% de sombreamento. Ambas as espécies podem ser plantadas sob pleno sol, 30%, 50% e 75% de sombreamento, sendo indicadas para a implantação de reflorestamentos ou  para enriquecimento de área degradadas.

Para avaliar o efeito da temperatura e velocidade do ar sobre a taxa de secagem, peças de madeira de Pinus elliottii de 25 x 125 x 750 mm foram submetidas à secagem em estufa semi-industrial de convecção forçada. O processo foi conduzido para duas temperaturas e duas velocidades de ar e controlado por meio de um sistema computadorizado. Os resultados mostraram que a taxa de secagem tem uma relação diretamente proporcional com a temperatura, velocidade do ar e umidade da madeira. Por meio da análise de regressão múltipla detectou-se efeito estatisticamente significativo da temperatura e da velocidade do ar sobre a taxa e o tempo de secagem, com um nível de confiança de 99%. Como a importância da velocidade do ar na secagem decresce com a diminuição do teor de umidade, sugere-se, por razões de economia, mais investigações acerca das relações entre as duas variáveis durante o período de taxa de secagem decrescente.

Com o objetivo de avaliar os efeitos de doses crescentes de Zn sobre o teor, o conteúdo e o índice de translocação de nutrientes, mudas de cedro foram conduzidas em solução nutritiva de Clark, em condições de casa de vegetação do Departamento de Ciência do Solo da Universidade Federal de Lavras, e submetidas a doses crescentes de Zn: 2, 76, 152, 304 e 456 µmol L-1, adotando-se para tal um delineamento estatístico de blocos ao acaso. Ao final de 60 dias de exposição ao metal pesado, foram feitas avaliações do teor e do conteúdo de macro e de micronutrientes na matéria seca de raiz, caule, folhas, parte aérea e total, bem como da translocação desses nutrientes da raiz para a parte aérea. Os resultados mostram que, de maneira geral, há resposta diferenciada nos teores e redução no conteúdo de macro e de micronutrientes, independente da parte da planta analisada, ao passo que o índice de translocação de nutrientes é crescente com as doses de Zn aplicadas.

Com o objetivo de avaliar a deposição estacional de serapilheira em uma Floresta Ombrófila Mista, instalou-se um experimento em setembro/98 na Estação Experimental de São João do Triunfo, no estado do Paraná. A estação possui uma área de 31,7 ha, dividida em trinta parcelas de 1 ha. Em três dessas parcelas foram instalados 27 coletores (nove em cada uma). As coletas foram realizadas a cada 45 dias, atentando-se sempre para o final das estações. O material coletado foi acondicionado em sacos plásticos, os quais foram identificados com o número do coletor e a parcela na qual está localizado. Após uma pré-secagem, o material de cada coletor foi separado nas frações folhas, galhos e miscelânea. Em seguida, estas foram embaladas em sacos de papel e levadas à estufa à temperatura de 65oC, até peso constante, para a determinação do peso seco por fração de serapilheira. Os dados obtidos até o momento demonstram que a primavera foi a estação que apresentou a maior deposição de serapilheira, seguida pelo inverno, verão e outono, com valores médios (kg/ha) de 2.433,31; 2.164,79; 1.799,72 e 1.339,00 respectivamente. A fração folhas constituiu-se no principal componente, respondendo por 57% da serapilheira total, seguida por galhos com 27% e miscelânea com 16%.

Catorce procedencias de Acacia saligna fueron evaluadas en función del crecimiento a los 15 meses en dos sitios del norte de Chile. Correlaciones genéticas tipo B fueron estimadas para examinar la interacción genotipo x ambiente (G x A) del crecimiento en altura total, diámetro medio de copa y diámetro de cuello. Máxima Verosimilitud Restringida (REML), fue el método utilizado para la estimación de componentes de varianza. Para el crecimiento en altura, la correlación genética fue moderada (ΓpB = 0,46). Para diámetro de cuello y diámetro medio de copa, los valores de correlación genética mostraron un valor bajo (ΓpB = 0,27 y 0,17, respectivamente), indicando una alta interacción G x A. Los resultados mostraron diferencias significativas entre las procedencias, en cada sitio estudiado (p ≤ 0,01). El crecimiento promedio de las procedencias varió entre los distintos sitios, mostrando mayor potencial hacia el sur de la Región. De persistir una alta interacción GxA en el tiempo, se hace necesario seleccionar grupos de procedencias específicos para cada sitio, debido a que no siempre el mejor grupo para un sitio específico mantuvo su superioridad en el otro.

Este trabalho teve como objetivo estudar a flutuação populacional de espécies da ordem Coleoptera em plantio de Eucalyptus urophylla no município de Almerin, estado do Pará. Esses insetos foram coletados com armadilhas luminosas durante uma noite, a cada quinze dias, de setembro de 1995 a agosto de 1996 com os exemplares identificados de acordo com coleções entomológicas e com a literatura especializada, e divididos em grupos identificados em nível de espécie (INE) ou de família (INF). Foram coletados 132 espécies da ordem Coleoptera, sendo 23 identificadas por espécie e 109 por família, com 2972 e 7187 indivíduos respectivamente. As espécies mais abundantes foram Anomala sp.1, Leucothireus sp. (Scarabaeidae) e Ciclocephala lamminata (Dynastidae) com 93,4% dos indivíduos do primeiro grupo. Carabidae apresentou o maior número de indivíduos (6411) e de espécies (31) dos insetos identificados por família. Todas as coletas apresentaram indivíduos da ordem Coleoptera, com maior número de exemplares dessa ordem em janeiro de 1996.

O objetivo deste trabalho foi produzir chapas de partículas "Strand" e maravalhas partindo de Schizolobium parahyba e Erytrina verna e suas combinações. Os parâmetros de manufatura foram: densidade nominal de 0,65 g/cm³, temperatura de prensagem de 180ºC, tempo de prensagem de 14 minutos, resina fenol-formaldeído a 8% e umidade das partículas a 5%. Os melhores resultados para o ensaio de flexão estática foram encontrados quando se utilizou guapuruvu puro e/ou na capa, embora a maioria dos tratamentos tenha apresentado valores superiores aos estabelecidos pela norma canadense (CSA O437-0, 1993). Em relação à ligação interna, 50% dos tratamentos apresentaram valores superiores aos estabelecidos pela norma canadense. Os valores de absorção de água e inchamento em espessura foram considerados altos para todos os tratamentos, devendo-se considerar que não foi utilizado parafina para a confecção das chapas.

Published: May 2017

A Floresta Estacional Decidual da região nordeste de Goiás é um tipo de vegetação florestal do grande bioma Cerrado, que pode ocorrer em áreas de afloramento de calcário e, geralmente, apresenta maior biomassa de espécies arbóreas que a vegetação de cerrado adjacente. Este estudo foi desenvolvido em uma área de floresta intacta (Fazenda Flor Ermo) e em quatro áreas de floresta perturbada (Fazendas Formosa, Traçadal, Manguinha e Conçeição Mocambo). O objetivo foi estimar a área basal e a intensidade amostral utilizando o relascópio de Bitterlich em florestas deciduais. A área basal foi de 29,3 m²/ha na floresta intacta e de 23 a 24 m²/ha nas perturbadas. As florestas com perturbação acentuada apresentaram curvas de distribuição do desvio padrão dos pontos de amostragem com pequena variação comparada com a curvas das áreas com baixo nível de perturbação. Para um limite de confiança de 95 % de probabilidade de confiança para a estimativa da média, 20 unidades amostrais com o relascópio podem ser suficientes para amostrar satisfatoriamente a área basal nesse tipo de vegetação.

Duas espécies de Pinus (Pinus elliottii e Pinus taeda) foram utilizadas para realizar o presente estudo. Procurou-se correlacionar através de uma equação de regressão linear, o teor de umidade e a concentração da madeira, considerando três ângulos de grã (30º, 45º e 90º). Existe para as duas espécies uma alta correlação entre a concentração e o teor de umidade da madeira, entre o P.S.F. e o O% de umidade, para os diferentes ângulos estudados. As equações de regressão linear encontradas para ambas espécies, podem ser usadas sem maiores erros de cálculos para a determinação da contração da madeira a diferentes teores de umidade.
