O TRABALHO DE HOMENS E MULHERES NO TURISMO RURAL EM SÃO JOSÉ DOS AUSENTES: O “LEVE” E O “PESADO”
Authors: Lunardi Raquel , De Souza Marcelino , Perurena Fátima
Published: June 2015

Este trabalho tem como objetivo estudar as relações de trabalho na atividade turística no meio rural de São José dos Ausentes. As mudanças produtivas ocorridas no meio rural por meio da diversificação das culturas agrícolas e da inserção de atividades não agrícolas no espaço rural têm permitido um novo debate sobre o desenvolvimento rural. Novas formas de uso do espaço rural estão postas e com elas novas formas de organização da vida familiar, cuja divisão do trabalho é uma das esferas mais afetadas. A proximidade entre as tarefas realizadas no ambiente doméstico com a atividade produtiva turismo rural permite que homens e mulheres desenvolvam e reestruturem suas funções dentro da unidade familiar. Porém, não se sabe se estas mudanças permitem transformações na divisão sexual do trabalho e se isto possibilita repensar as estruturas de gênero no meio rural. Para compreender essa teia de relações, foi preciso refletir sobre as relações internas à família, como a organização das tarefas diárias, o sistema produtivo e a participação de cada membro nas decisões que envolvem o grupo familiar. Para isso pesquisaram-se sete famílias pluriativas e seis famílias agrícolas no meio rural do município de São José dos Ausentes, RS. De forma geral, pode-se sinalizar para uma reprodução da forma tradicional da divisão sexual do trabalho nas famílias rurais pesquisadas, sobretudo no que diz respeito ao trabalho feminino no momento em que velhas práticas são reafirmadas pelo turismo. Palavras-Chave: Turismo rural. Trabalho. Gênero.
The Effectiveness of Mexico’s Faculty Improvement Program (Promep) in Public State Universities
Authors: Guzman Teresa , Martínez-Arcos Cruz Alberto
Published: June 2015

This article evaluates the effectiveness of Promep, a faculty improvement program implemented by Mexico’s Federal Department of Public Education (SEP) since 1996 to improve the academic qualifications, performance, and organization of faculty at the public higher education institutions. This evaluation examines the degree to which Promep has achieved its quantitative objectives with regard to the Public State Universities (PSU), which is the higher education subsystem that Promep has been active in for the longest period of time (1996–2013). The evaluation is based on numerous data reports published by Promep, the SEP, and other federal institutions as well as on essential subsystem-wide indicators calculated from data individually collected from each of the PSU for the purposes of this study. The results indicate that Promep has significantly improved the academic qualifications, performance, and organization of the full-time faculty staff of the PSU, but also that by 2013 the program has not been able to meet the quantitative goals it expected to achieve by late 2008, which was its initial deadline. The study suggests that the failure to achieve these initial and manageable goals has occurred mostly because many PSU have allowed the infringement of their own faculty recruitment, permanence, and promotion regulations and Promep has failed to stop these practices through the establishment of more drastic strategies, such as binding agreements and penalization schemes.
What Goes around Comes around: The Impact of Marketing Alliances on Firm Risk and the Moderating Role of Network Density
Authors: Thomaz Felipe , Swaminathan Vanitha
Published: June 2015

Although the value gained from partnership formation (through alliances) or through the firm's position in a network has received significant research attention, little is known about the risks that can accompany this increasing reliance on partners. The authors investigate the change in firm idiosyncratic and systematic risks after the announcement of marketing alliances and analyze whether the density of the firm's network of alliance partners moderates the risk exposure, demonstrated through investors' expectations of a firm's risk or the equity risk of a firm. The results indicate that marketing alliances reduce firm risk, so long as the alliance is a novel connection between the partnering firms. Furthermore, at high levels, the interconnectedness of partners or density of a firm's network can cause idiosyncratic risk to increase, and the density of a partner's network can also result in increases in systematic risk of a firm after alliance formation.
Lagrangian F-stability of closed Lagrangian self-shrinkers
Authors: Li Jiayu , Zhang Yongbing
Published: June 2015

In this paper we study the Lagrangian F-stability of closed Lagrangian self-shrinkers in complex Euclidean space.
We show that any closed Lagrangian self-shrinker with first Betti number greater than one is Lagrangian F-unstable.
For a closed Lagrangian self-shrinker with first Betti number equal to one,
we show that Lagrangian F-stability is equivalent to Hamiltonian F-stability.
We also characterize Hamiltonian F-stability of a closed Lagrangian self-shrinker by its spectral property of a drift Laplacian.

Let D be a division ring with center k and multiplicative group D
†, and let N be a normal subgroup of D
†. Assuming that N contains a subgroup G which is nonabelian torsion-free polycyclic-by-finite (not abelian-by-finite), we construct a free noncyclic subgroup of N in terms of elements of G. We also show that if char(k) ≠ 2, D is generated over k by the torsion-free polycyclic-by finite group G (not abelian-by-finite), and if it is possible to extend the involution
x*

Violently Peaceful: Tibetan Self-Immolation and the Problem of the Non/Violence Binary
Authors: Soboslai John
Published: June 2015

The paper investigates the conceptual dichotomy of violence and nonviolence in reference to the self-immolations that have been taking place in Tibet for the last several years. First using the insights of Hannah Arendt to distinguish between the categories of violent, nonviolent and peaceful, I approach the question of violence as the problem of acts that transgress prohibitions against causing harm. Using that heuristic, I examine the ways multiple ethical systems are vying for recognition regarding the selfimmolations, and how a certain Buddhist ambivalence around extreme acts of devotion complicate any easy designations of the act as ‘violent’ or ‘nonviolent’. I conclude by suggesting how any such classification inculcates us into questions of power and assertions of appropriate authority.

Published: June 2015

An analysis of dense cements, such as polymer cement concrete, is made to produce original innovative components for different types of constructing materials. These materials present good functional properties (ageing resistance, crack formation resistance, hardness, and stability of mechanical modules) and can be used for various applications. In this paper, experimental tests on Portland cement with added γ-Al2O3 and redispersible dry polymer performed using small angle neutron scattering are reported. The objective of the investigation was to assess the key parameters of the material (e.g., porosity, fractal dimensions, and size distribution) at the nanoscale level as well as to obtain useful structural information for expanding the possibility of applications. The results obtained can contribute to the optimisation of the consistency of the material, the design of operating conditions of elements of structures and facilities, and the design of the procedures that support ecological criteria and enhance quality and safety levels.
Eleventh Dynasty Written Evidence on the ­Relationship between the
k˒͗
and the Cult Image
Authors: Demidchik Arkadiy E.
Published: June 2015

The article points to some additional written evidence on the relation between the k˒͗-concept and the cult image. It is argued that connection with the latter was essential and inherent for the ḥw.t-k˒͗ and the service of the ḥm-k˒͗. The inscriptions on JE 46068, BM EA 627 and BM EA 1164, by highlighting the cult image-twt as recipient of the boons provided for the k˒͗, almost equate these two notions, that is best explainable if the cult image was considered as “door” for the k˒͗’s “going forth”. Such revealing deviations from the Old Kingdom written tomb etiquette may have been induced by the rarity of tomb sculpture and some innovations in its use in the First Intermediate Period.

This small Middle Kingdom sculpture is approximately datable to the reign of King Amenemhat II and is one of the earliest preserved block statues. The inscription added hundreds of years after the statue’s creation, sometime between the Ramesside Period and the Third Intermediate Period reflects the regard in which the object was held, even in ancient times.
Wenn Archäologie und Philologie nicht harmonieren
Authors: Theis Christoffer
Published: June 2015

The article compiles all in situ finds of magical bricks, which were placed in niches around the body inside the grave that are known so far. It is demonstrated that the text of the ritual described in the Book of the Dead spell 151 is not put to practice exactly as written. The archaeological evidence shows an entirely different approach by the ancient priests, who used the bricks in a more practical way rather than following the strict instructions described in BD 151.
Regulation of Peripheral Nerve Myelin Maintenance by Gene Repression through Polycomb Repressive Complex 2
Authors: Ma Ki H. , Hung Holly A. , Srinivasan Rajini , Xie Huafeng , Orkin Stuart H. , Svaren John
Published: June 2015

Myelination of peripheral nerves by Schwann cells requires coordinate regulation of gene repression as well as gene activation. Several chromatin remodeling pathways critical for peripheral nerve myelination have been identified, but the functions of histone methylation in the peripheral nerve have not been elucidated. To determine the role of histone H3 Lys27 methylation, we have generated mice with a Schwann cell-specific knock-out of Eed, which is an essential subunit of the polycomb repressive complex 2 (PRC2) that catalyzes methylation of histone H3 Lys27. Analysis of this mutant revealed no significant effects on early postnatal development of myelin. However, its loss eventually causes progressive hypermyelination of small-diameter axons and apparent fragmentation of Remak bundles. These data identify the PRC2 complex as an epigenomic modulator of mature myelin thickness, which is associated with changes in Akt phosphorylation. Interestingly, we found that Eed inactivation causes derepression of several genes, e.g.,Sonic hedgehog(Shh) andInsulin-like growth factor-binding protein 2(Igfbp2), that become activated after nerve injury, but without activation of a primary regulator of the injury program, c-Jun. Analysis of the activated genes in cultured Schwann cells showed that Igfbp2 regulates Akt activation. Our results identify an epigenomic pathway required for establishing thickness of mature myelin and repressing genes that respond to nerve injury.

Multiple sclerosis (MS) is a demyelinating disease of the CNS characterized by inflammation and neurodegeneration. Animal models that enable the study of remyelination in the context of ongoing inflammation are greatly needed for the development of novel therapies that target the pathological inhibitory cues inherent to the MS plaque microenvironment. We report the development of an innovative animal model combining cuprizone-mediated demyelination with transfer of myelin-reactive CD4+T cells. Characterization of this model reveals both Th1 and Th17 CD4+T cells infiltrate the CNS of cuprizone-fed mice, with infiltration of Th17 cells being more efficient. Infiltration correlates with impaired spontaneous remyelination as evidenced by myelin protein expression, immunostaining, and ultrastructural analysis. Electron microscopic analysis further reveals that demyelinated axons are preserved but reduced in caliber. Examination of the immune response contributing to impaired remyelination highlights a role for peripheral monocytes with an M1 phenotype. This study demonstrates the development of a novel animal model that recapitulates elements of the microenvironment of the MS plaque and reveals an important role for T cells and peripheral monocytes in impairing endogenous remyelinationin vivo. This model could be useful for testing putative MS therapies designed to enhance remyelination in the setting of active inflammation, and may also facilitate modeling the pathophysiology of denuded axons, which has been a challenge in rodents because they typically remyelinate very quickly.
Persistent Nociception Triggered by Nerve Growth Factor (NGF) Is Mediated by TRPV1 and Oxidative Mechanisms

Published: June 2015

Nerve growth factor (NGF) is elevated in certain chronic pain conditions and is a sufficient stimulus to cause lasting pain in humans, but the actual mechanisms underlying the persistent effects of NGF remain incompletely understood. We developed a rat model of NGF-induced persistent thermal hyperalgesia and mechanical allodynia to determine the role of transient receptor potential vanilloid 1 (TRPV1) and oxidative mechanisms in the persistent effects of NGF. Persistent thermal hypersensitivity and mechanical allodynia requirede novoprotein translation and are mediated by TRPV1 and oxidative mechanisms. By comparing effects after systemic (subcutaneous), spinal (intrathecal) or hindpaw (intraplantar) injections of test compounds, we determined that TRPV1 and oxidation mediate persistent thermal hypersensitivity via peripheral and spinal sites of action and mechanical allodynia via only a spinal site of action. Therefore, NGF-evoked thermal and mechanical allodynia are mediated by spatially distinct mechanisms. NGF treatment evoked sustained increases in peripheral and central TRPV1 activity, as demonstrated by increased capsaicin-evoked nocifensive responses, increased calcitonin gene-related peptide release from hindpaw skin biopsies, and increased capsaicin-evoked inward current and membrane expression of TRPV1 protein in dorsal root ganglia neurons. Finally, we showed that NGF treatment increased concentrations of linoleic and arachidonic-acid-derived oxidized TRPV1 agonists in spinal cord and skin biopsies. Furthermore, increases in oxidized TRPV1-active lipids were reduced by peripheral and spinal injections of compounds that completely blocked persistent nociception. Collectively, these data indicate that NGF evokes a persistent nociceptive state mediated by increased TRPV1 activity and oxidative mechanisms, including increased production of oxidized lipid TRPV1 agonists.

Published: June 2015

Intracortical brain–machine interfaces (BMIs) may eventually restore function in those with motor disability after stroke. However, current research into the development of intracortical BMIs has focused on subjects with largely intact cortical structures, such as those with spinal cord injury. Although the stroke perilesional cortex (PLC) has been hypothesized as a potential site for a BMI, it remains unclear whether the injured motor cortical network can support neuroprosthetic control directly. Using chronic electrophysiological recordings in a rat stroke model, we demonstrate here the PLC's capacity for neuroprosthetic control and physiological plasticity. We initially found that the perilesional network demonstrated abnormally increased slow oscillations that also modulated neural firing. Despite these striking abnormalities, neurons in the perilesional network could be modulated volitionally to learn neuroprosthetic control. The rate of learning was surprisingly similar regardless of the electrode distance from the stroke site and was not significantly different from intact animals. Moreover, neurons achieved similar task-related modulation and, as an ensemble, formed cell assemblies with learning. Such control was even achieved in animals with poor motor recovery, suggesting that neuroprosthetic control is possible even in the absence of motor recovery. Interestingly, achieving successful control also reduced locking to abnormal oscillations significantly. Our results thus suggest that, despite the disrupted connectivity in the PLC, it may serve as an effective target for neuroprosthetic control in those with poor motor recovery after stroke.

Over the past decades, tremendous efforts have been made to establish pancreatic islet transplantation as a standard therapy for type 1 diabetes. Recent advances in islet transplantation have resulted in steady improvements in the 5-year insulin independence rates for diabetic patients. Here we review the key challenges encountered in the islet transplantation field which include islet source limitation, sub-optimal engraftment of islets, lack of oxygen and blood supply for transplanted islets, and immune rejection of islets. Additionally, we discuss possible solutions for these challenges.

Published: June 2015

Background & Aims: Non-Alcoholic Fatty Liver Disease (NAFLD) is the commonest cause of chronic liver disease in the western world. Current diagnostic methods including Fibroscan have limitations, thus there is a need for more robust non-invasive screening methods. The gut microbiome is altered in several gastrointestinal and hepatic disorders resulting in altered, unique gut fermentation patterns, detectable by analysis of volatile organic compounds (VOCs) in urine, breath and faeces. We performed a proof of principle pilot study to determine if progressive fatty liver disease produced an altered urinary VOC pattern; specifically NAFLD and Non-Alcoholic Steatohepatitis (NASH).Methods: 34 patients were recruited: 8 NASH cirrhotics (NASH-C); 7 non-cirrhotic NASH; 4 NAFLD and 15 controls. Urine was collected and stored frozen. For assay, the samples were defrosted and aliquoted into vials, which were heated to 40±0.1°C and the headspace analyzed by FAIMS (Field Asymmetric Ion Mobility Spectroscopy). A previously used data processing pipeline employing a Random Forrest classification algorithm and using a 10 fold cross validation method was applied.Results: Urinary VOC results demonstrated sensitivity of 0.58 (0.33 - 0.88), but specificity of 0.93 (0.68 - 1.00) and an Area Under Curve (AUC) 0.73 (0.55 -0.90) to distinguish between liver disease and controls. However, NASH/NASH-C was separated from the NAFLD/controls with a sensitivity of 0.73 (0.45 - 0.92), specificity of 0.79 (0.54 - 0.94) and AUC of 0.79 (0.64 - 0.95), respectively.Conclusions: This pilot study suggests that urinary VOCs detection may offer the potential for early non-invasive characterisation of liver disease using 'smell prints' to distinguish between NASH and NAFLD.
Recent data on the causative agent of pale green dwarf (Acholeplasma laidlawii var. granulum incertae sedis) in Ukraine: pathogenicityand virulence factors and host reactions
Authors: Korobkova K. , Patyka V.
Published: June 2015

Contemporary state of the distribution of mycoplasma diseases of cultivated crops in Ukraine was analyzed. The changes of the physiological state of plant cells under the impact of mollicutes were investigated. It was demonstrated that there is temporary increase in the activity of peroxidase, catalase, polyphenoloxidase, phenylalanine-ammonia-lyase at the early stages of interaction. The adhesive properties are changed in the mollicutes under the impact of plant lectin; there is synthesis of new polypeptides. It was determined that the phytopathogenic acholeplasma is capable of producing a complex of proteolytic enzymes into the culture me- dium. It was concluded that when plant cells are infected with acholeplasma, a number of signaling interactions and metabolic transformations condition the recognition of pathogenesis and ensure the aggregate response of a plant to stress in the form of defense reactions. It was assumed that some specifi cities of the biology of phy- topathogenic acholeplasma determine
their avoiding the immune mechanisms of plants and promote long-term persistence of mollicutes.
El crudo despertar de Lázaro de Betania

Published: June 2015

En este escrito se discute cómo el personaje principal de la novela costarricense El despertar de Lázaro (2003) de Julieta Pinto, rompe con el eterno silencio del personaje bíblico, con lo cual se deconstruye el relato bíblico y se logra percibir a Lázaro como a una persona real, de “carne y hueso”. Asimismo, experimenta un doble exilio, en tanto una vez muerto es forzado a regresar a la vida; ya no pertenece a la vida ni a la muerte. Como resultado, este personaje literario se instaura como el otro o la alteridad inaceptable.

György Martin’s place in applied ethnochoreology
Authors: Quigley Colin
Published: June 2015

Apart from a few key works on dance structure, improvisation and Central European traditional dance, the breadth and depth of Martin’s work remains inaccessible to the English reading audience and little known in dance studies. One such unacknowledged area of significant contribution is his important work in applied ethnochoreology through key interventions in Hungarian presentational stage choreography and participatory social dance revival. In both spheres Martin made a significant contribution at key moments in their development. At least two fundamental concepts drawn from his theoretical work informed his activist interventions. First, that folk dancing needs to be conceptualized, and studied, as a process (táncfolyamat). Second, that this process cannot be excised from its complete contextualization in the lives and history of its practitioners if it is to be fully understood. This theori-zation of dance is relevant far beyond the village dance idiom that so absorbed him. It should be more widely known, acknowledged and, indeed, applied specifically within ethnochoreology as well as dance studies in general today. As work in the application of scholarly knowledge outside the walls of academia becomes ever more important in our field, it is worth remembering that this is not an activity without precedent. Martin’s theoretically informed interventions in both participatory and presentational dance practices in Hungary provide an excellent model for such work.

Growth of Hexagonal Boron Nitride on Microelectronic Compatible Substrates
Authors: Snure Michael , Paduano Qing S.
Published: June 2015

Boron nitride has attracted a great deal of attention as a two dimensional (2D) insulator for substrate and gate dielectric applications in 2D electronics. Development of a scalable technique to grow mono- to few-layer h-BN on microelectronics compatible substrates is desirable. Work on the growth of atomically smooth BN and graphene on sapphire and Si is presented in this paper. Two approaches are described: i) growth of h-BN and graphene on Si and sapphire substrates using a catalyzing Cu thin film, and ii) low pressure metal organic chemical vapor deposition (MOCVD) growth on sapphire. In approach i) we discuss problems associated with the thermal instability of Cu at the interface with the substrate and show how the stability may be improved through the use of a thin Ni buffer layer or careful substrate selection. The correlation between Cu film morphology and h-BN (and graphene) quality is shown. In approach ii) we find two different growth modes, 3D island growth at low V/III ratios and self-terminating growth at high V/III ratios. Under self-terminating growth atomically smooth few-layer h-BN films are produced. Nitridation of the sapphire surface is found to promote this self-terminating growth by improving nucleation of BN on the substrate. Finally, we present results from the growth of graphene/h-BN on sapphire in a single process.

Molybdenum disulfide (MoS2), one of the transition-metal dichalcogenides, is a 2-dimensional semiconducting material that has a layered structure. Owing to excellent optical and electronic properties, the ultra-thin MoS2 film is expected to be used for various devices, such as transistors and flexible displays. In this study, we investigated the physical and chemical properties of sputtered-MoS2 film in the sub-10-nm region by Raman spectroscopy and X-ray photoelectron spectroscopy (XPS). As the results of Raman spectroscopy investigations, we observed two Raman modes, E12g and A1g, in the 2-dimensional MoS2 films. As the thickness of the MoS2 film decreased, the peak frequency difference between E12g and A1g modes increased. From the XPS investigations, we confirmed sulfur reductions from the 2-dimensional MoS2 films. Therefore, we considered that the sulfur vacancies in the MoS2 film affected the Raman peak positions. Moreover, we performed the additional sulfurization of sputtered-MoS2 films. From the XPS and Raman investigations, the quality of the sputtered-MoS2 films was improved by the additional sulfurization.
A cell-based smoothed discrete shear gap method (CS-FEM-DSG3) for dynamic response of laminated composite plate subjected to blast loading
Authors: Hau Dang Trung , Hanh Nguyen Thoi My , Trung Nguyen Thoi
Published: June 2015

The paper investigates the dynamic response of laminated composite plate under the effect of blast loading. The cell-based smoothed discrete shear gap method (CS-FEM-DSG3) based on the first-order shear deformation theory (FSDT) and the equivalent layer theory (ELT) is used to model the behavior of the laminated composite plate. The blast loading is simulated by a time diagram of rectangular, triangular, exponential, or sinusoidal shape. The effects of the number of layers and fiber orientation to the displacement and stress fields of the laminated composite plate are discussed. Numerical results demonstrated the accuracy and reliability of the present method compared with previous published methods.
Actuator saturation control of a benchmark structure using hedge-algebras-based fuzzy controller
Authors: Le Bui Hai
Published: June 2015

In this paper, the problem of actuator saturation control of a benchmark structure using hedge-algebras-based fuzzy controller (HAC) is presented. In HAC, linguistic values of linguistic terms are obtained through semantically quantifying mappings (SQMs) based on few fuzziness parameters of each linguistic variable without using any fuzzy set and inherent order relationships between linguistic values of each linguistic variable are always ensured. Hence, the design of a HAC leads to determining parameters of SQMs, which are fuzziness measures of primary terms and linguistic hedges occurring in a fuzzy model. As a case study, a HAC is designed to actuator saturation control of a benchmark structure with active bracing system (ABS) subjected to earthquake excitation. Control performance of the controller is also discussed in order to show advantages of the proposed method.

We investigate in detail  $one-loop$ contribution of new particles to the muon  anomalous magnetic moment \((g-2)_\mu\) in the framework of the economical 3-3-1 model. The main contributions to the anomalous magnetic moment come from new neutral gauge boson \(Z'\),  bilepton  singly charged  vector boson $Y^\pm$. The contributions of new neutral/charged scalars are small and can be neglected. The result is extended to other versions of 3-3-1 models.Comparing the anomalous magnetic moment value in this model with experimental value we set the extension requirement for the model.

In particular, the changes in luminescence intensity according to the pH value of the solution environment containing biosensor have been considered, before and after the presence of pesticides. The changes in luminescence intensity of the biosensor after the presence of pesticide over time from 2 seconds to 26 minutes were also surveyed. We have been carried out the tests to determine the trace amounts of commercial pesticides like Motox 5EC, containing 5% cypermethrin and Tungatin 10 EC, containing 10% abamectin, on the real samples of tealeaves. Some characteristics of the relationship between composition, structure, and special optical properties of ternary alloy quantum dots will also be presented. These studies open up the potential applications of  ternary quantum dots for agricultural production.
Monte Carlo Simulation on the Phase Transition of Animal Group
Authors: The Nguyen Phuoc , Thanh Ngo Van
Published: June 2015

In this work, we proposed a new model in order to study the phase transition behaviour of animal group. The individuals in the group are considered as the XY spins which can move freely in a plane with the same speed. For the interactions between every pairs of the individuals, we used the Hamiltonian of the system in the model of spin current with including a long-range Morse potential. Using the Monte-Carlo simulation technique, we obtained the main parameters of the model: the averaged velocity of all individuals which is equivalent to the order parameter or magnetization for the spin model, and the concentration of the individuals. The simulation result clearly shows that the system has three phases which correspond to the uncollected, flocking (schooling) and runaway behaviors at very low, medium and high noise, respectively. The simulation predictions are in good agreement with experimental observations.

A sample of 34 solar flares recorded in Ha Noi using the VATLY radio telescope between April 2012 and January 2014 at frequencies of 1415 and 1417.6 MHz is compared with the corresponding observations made at 1415 MHz by the solar observatory of Learmonth (Australia). While good overall agreement is obtained, a few differences are noted and studied in some detail. In particular, the use of different feeds in Ha Noi and Learmonth reveals a case of very large polarization of the flare emission.
Coherent structures in wall-bounded turbulence
Authors: Dennis David J.C.
Published: June 2015

The inherent difficulty of understanding turbulence has led to researchers attacking the topic in many different ways over the years of turbulence research. Some approaches have been more successful than others, but most only deal with part of the problem. One approach that has seen reasonable success (or at least popularity) is that of attempting to deconstruct the complex and disorganised turbulent flow field into to a set of motions that are in some way organised. These motions are generally called "coherent structures". There are several strands to this approach, from identifying the coherent structures within the flow, defining their characteristics, explaining how they are created, sustained and destroyed, to utilising their features to model the turbulent flow. This review considers research on coherent structures in wall-bounded turbulent flows: a class of flow which is extremely interesting to many scientists (mainly, but not exclusively, physicists and engineers) due to their prevalence in nature, industry and everyday life. This area has seen a lot of activity, particularly in recent years, much of which has been driven by advances in experimental and computational techniques. However, several ideas, developed many years ago based on flow visualisation and intuition, are still both informative and relevant. Indeed, much of the more recent research is firmly indebted to some of the early pioneers of the coherent structures approach. Therefore, in this review, selected historical research is discussed along with the more contemporary advances in an attempt to provide the reader with a good overview of how the field has developed and to highlight the perspicacity of some of the early researchers, as well as providing an overview of our current understanding of the role of coherent structures in wall-bounded turbulent flows.

Com o surgimento de áreas degradadas por ações antrópicas, os atributos químicos do solo e os caracteres silviculturais passaram a ter importância quanto ao entendimento do processo sucessional das espécies arbóreas e ao planejamento de recomposição da paisagem. Assim, este trabalho teve como objetivo avaliar a distribuição de espécies arbóreas em áreas com diferentes níveis de antropização, relacionando aspectos silviculturais com os atributos químicos do solo e caracterizando o tipo de vegetação, para fins de integração de programa de conservação genética in situ. O trabalho foi desenvolvido em área da Fazenda Experimental de Pesquisa e Extensão (FEPE) da UNESP, de Ilha Solteira, no Município de Selvíria, MS. Por meio de transecto, foram demarcadas 64 parcelas equidistantes de 50 m com dimensões de 10 x 10 m, sendo 29 parcelas em área altamente antropizada (AAA), cinco em área medianamente antropizada (AMA), 15 em área pouco antropizada (APA), seis na Mata Ciliar do córrego da Véstia (Mata Ciliar) e nove na Reserva Legal. As amostras de solo foram coletadas em duas profundidades (0,0 a 0,20 m e 0,20 a 0,40 m) para os atributos químicos, além da avaliação dos caracteres silviculturais, como altura, Diâmetro à Altura do Peito (DAP) e Forma. O estudo da distribuição natural de espécies arbóreas e condição edáfica nas diferentes áreas avaliadas permitiu concluir que os atributos químicos do solo, associados ao nível de antropização e conservação das áreas, estão influenciando a ocorrência natural, diversidade de espécies e desenvolvimento dos indivíduos arbóreos. A altura, DAP e Forma são bons indicadores para avaliar o crescimento da comunidade arbórea e relacioná-los aos atributos químicos do solo. A APA e a Reserva Legal apresentam maior ocorrência natural, número de indivíduos e número de espécies. Na Mata Ciliar, os valores de área basal, altura, forma e atributos químicos do solo foram superiores. Das 97 espécies encontradas, seis têm potencial para serem utilizadas num programa de conservação genética in situ. São elas: Astronium fraxinifolium, Terminalia argentea, Curatella americana, Cupania vernalis, Qualea jundiahy e Andira cuyabensis.

A erva-mate (Ilex paraguariensis A. St. Hil.) é uma espécie nativa brasileira de grande interesse econômico. Programas de melhoramento genético dessa espécie têm visado ao aumento da produtividade de biomassa e qualidade. A polinização controlada permite a combinação de características desejáveis da espécie. Para isso, técnicas adequadas de polinização controlada devem ser disponibilizadas. Este trabalho teve por objetivo definir uma metodologia para a polinização controlada de erva-mate. Para isso, utilizou-se um teste clonal de 15 anos de idade na Embrapa Florestas-Colombo-PR com nove tratamentos em flores de três árvores (repetições). As flores foram polinizadas em novembro de 2010 e os frutos, coletados em março de 2011. Os frutos e sementes produzidos foram quantificados e a viabilidade dos embriões, avaliada pelo teste de tetrazólio. Os dados foram analisados com base no procedimento GLM do programa R. Maior quantidade de frutos e sementes foi observada na polinização controlada comparativamente à polinização livre. Conclui-se que a polinização controlada após a antese dessa espécie deve ser realizada em dois dias consecutivos, para assegurar boa produção de sementes em erva-mate.

O bioma Pantanal pode ser considerado um ambiente de hipersazonalidade, onde há um período de inundação pronunciada seguido por extenso período seco com temperaturas muito elevadas. A diversidade de suas fitofisionomias ocasiona aportes de carbono para o solo em quantidade e qualidade distintas. Com esse foco, este trabalho teve por objetivo verificar o efeito do ciclo hidrológico do Pantanal (enchente, cheia, vazante e estiagem) sobre a dinâmica do estoque carbono orgânico do solo nas fitofisionomias de Cambarazal, de Floresta Ripária, de Cordilheira e de Espinheiral. Verificou-se que as fitofisionomias puderam ser separadas pela análise de componentes principais (ACP) em três grupos distintos, caracterizados pela reserva de nutrientes e pela acidez do solo. O estoque de carbono do solo está condicionado por fatores sazonais e igualmente dependentes da fitofisionomia local que ocorreram nas fitofisionomias que apresentaram maior nível de fertilidade natural, ou seja, respectivamente o Cambarazal e o Espinheiral. O maior teor de carbono foi observado no período de enchente, na maioria das fitofisionomias, e o menor estoque de carbono aconteceu no período de vazante (2008), após o período de anaerobiose em razão da enchente e antes que o período seco passasse a ser determinante.

Eucalyptus plantations represent a short term and cost efficient alternative for sequestrating carbon dioxide from the atmosphere. Despite the known potential of forest plantations of fast growing species to store carbon in the biomass, there are relatively few studies including precise estimates of the amount of carbon in these plantations. In this study it was determined the carbon content in the stems, branches, leaves and roots of a clonal Eucalyptus grandis plantation in the Southeast of Brazil. We developed allometric equations to estimate the total amount of carbon and total biomass, and produced an estimate of the carbon stock in the stand level. Altogether, 23 sample trees were selected for aboveground biomass assessment. The roots of 9 of the 23 sampled trees were partially excavated to assess the belowground biomass at a singletree level. Two models with DBH, H and DBH2H were tested. The average relative share of carbon content in the stem, branch, leaf and root compartments was 44.6%, 43.0%, 46.1% and 37.8%, respectively, which is smaller than the generic value commonly used (50%). The best-fit allometric equations to estimate the total amount of carbon and total biomass had DBH2H as independent variable. The root-to-shoot ratio was relatively stable (C.V. = 27.5%) probably because the sub-sample was composed of clones. Total stand carbon stock in the Eucalyptus plantation was estimated to be 73.38 MgC ha-1, which is within the carbon stock range for Eucalyptus plantations.
