De pai para filho: o paradoxo fundamental da masculinidade
Authors: Oliveira André Assis Breder , França Cassandra Pereira
Published: June 2019

Partindo da defesa de Silvia Bleichmar da masculinidade enquanto uma constituição que perpassa o paradoxo no qual o menino precisa, numa relação de amor, incorporar o pênis paterno para revestir de potência e legitimar sua posição sexuada, o presente artigo contempla as peculiaridades da relação paterno-filial enquanto fonte de afirmação e contradição, já que essa fantasmática identificatória será classificada pelo Eu como homossexual. As vicissitudes da relação entre filho e pai são abordadas do estádio pré-edipiano à adolescência deflagrando que os paradoxos deixados por esse laço, ainda que represente a fragilidade da identidade masculina como essencialmente defensiva, compõem uma posição mais fértil para o sujeito. O enigma de uma posição sexuada em busca de confirmação viril apresenta a conjectura de que o sujeito, buscando a solução para a falta simbólica, pode colocar em ato a fantasmática da incorporação e, assim, estar mais suscetível à submissão sexual violenta a outros homens.
Ensaio: da história às características do gênero na esfera literária
Authors: Ferragini Neluana Leuz de Oliveira
Published: June 2019

O gênero ensaio corresponde a uma modalidade discursiva com contornos maleáveis que pode circular em diferenciadas esferas da comunicação humana. No domínio literário, o ensaio combina conceitos e juízos, figuras e metáforas, críticas e análises. Trata-se de uma reflexão discursiva, cultivada por um processo de subjetivação artística cujo produto resulta em profunda contemplação de um tema e/ou análise de uma obra, período, estilo. Não obstante seja reconhecido como gênero argumentativo, ao ensaio como produção literária não se destinam maiores e mais detalhados estudos quanto às suas características. Dessa forma, a presente abordagem, propõe-se a apresentar uma categorização para o gênero, ancorada na perspectiva baktiniana de gêneros discursivos, ao observar as marcas linguístico-enunciativas, condições de produção, conteúdo temático e construção composicional. Para empreender a compilação de corpus para análise, deriva-se, metodologicamente, das seguintes etapas: i) investigação de textos-enunciados/obras que se intitulassem ensaio (s) e/ou abordassem o enunciado ensaio; ii) diagnóstico e apreciação do material; iii) seleção e estudo de textos representativos do gênero; iv) organização das características do ensaio na esfera literária. Nessa perspectiva, discorre-se sobre a genealogia do ensaio e apresenta-se uma organização para as regularidades e instabilidades do gênero a partir dos textos-enunciados analisados.
Dos relatos reflexivos do Estágio Supervisionado em Língua Portuguesa: a questão do regime enunciativo
Authors: Leite João De Deus , Agustini Cármen
Published: June 2019

À luz das teorizações de Benveniste sobre enunciação escrita, problematizamos e analisamos o modo como uma acadêmica do Curso de Letras: Língua Portuguesa e suas literaturas de uma instituição federal produz seus “relatos reflexivos” do Estágio Supervisionado em Língua Portuguesa. Estamos considerando que, no tempo da escrita, a acadêmica, já na condição de locutora, precisa lidar com as coerções implícitas e explícitas do gênero “relato reflexivo”, que integra o gênero “relatório final”, e com as coerções da “situação de discurso”, tendo por base a contingência da sala de aula. Dessa maneira, por meio da escrita, a acadêmica (re)elabora a sua experiência no Estágio Supervisionado, dado o processo de metaforização, que se constitui a partir de três tempos que constituem a narratividade da experiência: o tempo do fato vivido, o tempo da escrita e o tempo da leitura. As análises, pautadas em recortes discursivos, mostram os pontos de dispersão da escrita da acadêmica, já que, ao relatar a experiência supostamente exitosa no Estágio Supervisionado, pontos de contradição marcam o regime enunciativo das enunciações escritas da acadêmica, deixando flagrar seu processo de identificação com certos espaços de interpretação que o regime enunciativo implica.

Evolution of U.S. Presidential Discourse over 230 Years: A Psycholinguistic Perspective
Authors: Chen Xueliang , Hu Jie
Published: June 2019

Much of recent research on U.S presidential discourse has focused on the nexus between language forms and their underlying social processes and psychological states. However, little work has been done to shed light on how these latent characteristics have evolved over time. This study investigated the evolution of three psychological states (authenticity, affect, and time orientation) underlying U.S. presidential discourse over approximately 230 years (1789–2016). Based on one of the most comprehensive corpora of presidential speech transcripts, Linguistic Inquiry and Word Count (LIWC) 2015, a text analysis software, was utilized to explore these psychological states. To see the overall trend of these states across U.S. presidential history as a whole, initial analysis was based on LIWC indices, which showed that, 1) overall, authenticity level is on a steady increase in U.S. presidential discourse; 2) in the presidents’ speeches, positive emotions invariably outweigh negative emotions, and both types of emotion remain relatively constant in the long run; 3) the discourse of “focus on present” consistently outweighs the discourse of “focus on future”, which outweighs the discourse of “focus on past”. To see whether the general trend holds across different parties, a series of independent samples t-tests were first performed to check for significant difference. The results indicated that in all the three psychological states, there was no significant difference between the Democratic presidents and the Republican presidents, and that the trend in different parties is in agreement with the overall trend. Subsequent visualization of the LIWC indices according to party generally corroborated these results, with only one exception: authenticity levels are on a steady increase in the discourse of the Democratic presidents, but in the Republican presidents, there was a sharp increase in recent years.
Economic Analysis of Optimal Sample Size in Legal Proceedings
Authors: Megerdichian Aren
Published: June 2019

In many legal settings, a statistical sample can be an effective surrogate for a larger population when adjudicating questions of causation, liability, or damages. The current paper works through salient aspects of statistical sampling and sample size determination in legal proceedings. An economic model is developed to provide insight into the behavioral decision-making about sample size choice by a party that intends to offer statistical evidence to the court. The optimal sample size is defined to be the sample size that maximizes the expected payoff of the legal case to the party conducting the analysis. Assuming a probability model that describes a hypothetical court’s likelihood of accepting statistical evidence based on the sample size, the optimal sample size is reached at a point where the increase in the probability of the court accepting the sample from a unit increase in the chosen sample size, multiplied by the payoff from winning the case, is equal to the marginal cost of increasing the sample size.

Knowledge of the population fluctuation of a pest in an orchard allows the producer preventing and making use of techniques that control the insect pest before it causes economic damages. The objective of the present work was to verify fruit fly species population dynamics in a commercial of Psidium guajava L. (Myrtaceae) orchard in the Curimataú microregion of Paraíba, also to characterize the community of fruit flies through faunistic analysis as well. Fruits were collected biweekly, the total was 24 collections between August 2014 and July 2015 in the municipality of Nova Floresta-PB. Fruits were preferentially collected mature or at the beginning of maturation, differentiating fruits harvested on the soil, plants, and through PET traps containing different food attractants. After collection, fruits were kept in plastic trays filled with a layer of two centimeters of sterilized sand and covered with fabric ‘voil’. The trays were labeled with the field data and placed in a greenhouse. Past the period of 15-25 days the fruits, already in the stage of decomposition were examined in order to collect pupae and larvae of 3rd instar. A total of 462 specimens of fruit flies were collected in 12 months sampling period, they were collected from fruits gathered from the ground and from the tree, and through trapping, being 209 males and 253 females, all collected in P. guajava. From the results obtained during the sampling period, a total of four species were recorded by fruit collection and six species by a trap. A new specimen of Anastrepha was found that there was no register in Paraíba yet, Anastrepha hadropickeli Canal, Uramoto and Zucchi (2013), as well as a Rhagoletis sp. (Loew).

The sugar and alcohol sector have invested heavily in technologies to increase the productivity of sugarcane and consequently the gross income of sugar and alcohol; among these practices irrigation and fertilization stands out. Based on the hypothesis that the source and the availability of nitrogen influence the growth, development and yield of irrigated sugarcane in the cerrado region, this study aimed to evaluate the accumulation of biomass and yield to define the best source and dose of nitrogen fertilization in irrigated sugarcane, in the cane-plant cycle, in a very clayey dystrophic Red Latosol, cerrado phase. The experiment was carried out at the Raízen Plant, located in the municipality of Jataí-GO. Brazil. The variety IACSP95-5000 was used in a randomized block experimental design, analyzed in a split-split-plot scheme, with four replicates. The factors evaluated were in the plots of four N rate (0, 60, 120 and 180 kg ha-1); In the split-plot two N sources (urea and ammonium nitrate) and as split-split-plot were represented by four evaluation periods (210, 250, 290 and 330 days after the planting-DAP). The irrigation was by sprinkling, performed by a central pivot. The highest gross sugar yield and gross alcohol yield in the average source of 131.72 kg N ha-1 had an average increase of 32.19%, compared to without N application 0 kg N ha-1.

Published: June 2019

This investigation was a case study of designs for grid-tie photovoltaic systems in agribusiness enterprises in the western region of the state of Paraná, in Brazil. Electricity consumption data of three grain storage enterprises and a complex with three aviaries was studied. Their monthly electricity consumption and production costs data were collected, and solar radiation data for the same locations were collected from the SunData database. Indices that related electricity costs and production expenses, and the photovoltaic system costs and production expenses were developed. The indices showed to be efficient tools of cost relation for systems of different installed powers and different agricultural productions. The study showed a cost reduction in production of up to 62.71% for the aviaries, and 76.87% for the grain storage enterprises, concluding that the use of grid-tie photovoltaic systems reduces the cost of production and increases the profit of the enterprises.

The present study aimed to assess the drying kinetics of black rice and fit different mathematical models (empirical and diffusive) to the experimental data, and evaluate the effect of drying air temperature on the physical-chemical and bioactive compounds quality of black rice. Drying air temperatures ranged from 40 to 80 ºC and the drying air speed was 1.5 m/s. Physical-chemical characterization of the product was based on the following parameters: moisture, water activity, ashes, total protein content, pH, total acidity, lipids, total carbohydrates, total anthocyanins, flavonoids, total phenolic compounds and antioxidant activity. Among the empirical models, Page showed the lowest mean squared deviations (MSD) and highest coefficients of determination (R2). For the diffusion model, the values of effective mass diffusivity and convective heat transfer coefficient increased with increasing drying air temperature, and the Biot number indicated that the first-type boundary condition would also describe well the drying process. Physical-chemical parameters and bioactive compounds differed between the temperatures used, and the temperature of 60 ºC led to the best relationship between drying time and preservation of product characteristics.

The objective of this work was to propose models of equations from measurements of the linear dimensions of the last leaflet for the estimation of the leaf area of the composite leaves of Canavalia rosea. For this purpose, 441 composite leaves of 198 seedlings were used, 45 days after sowing, produced in nursery and belonging to the Federal University of Espírito Santo, Campus São Mateus, located in the municipality of São Mateus, North of the State of Espírito Santo, Brazil. The length (L) along the main midrib and the maximum leaf width (W) of the last leaflet of each composite leaf, as well as the leaf area of all leaflets, were measured. Subsequently, it was determined the product of the multiplication of the length with the width (LW) and leaf area observed (OLA) from the sum of leaf area of leaflets in front of these measures were adjusted linear and non-linear equations of linear first degree, quadratic and power models, where, OLA was used as a dependent variable in function of L, W and LW as independent variable. Based on the models tested, we obtained equations for the estimated leaf area (ELA). The mean values of ELA and OLA were compared by Student's t test 5% probability. The mean absolute error (MAE), the root mean square error (RMSE) and the Willmott d index, were determined as criteria for validation. The best adjusted equation was chosen through the non-significant values in the comparison of the means of ELA and OLA, values of MAE and RMSE closer to zero, value of the index d near the unitary and higher values of R2. Thus, the leaf area of the composite leaf of C. rosea seedlings can be estimated by the power model represented by equation ELA = 2.2951 (LW)0.9474 quickly, easily and non-destructively.
The Influences of Sio2 on the Sintering Behavior and the Properties of Na+- Β/Β"-Al2O3 Solid Electrolyte
Authors: LEE Sung-Tae , LEE Dae-Han , LIM Sung-Ki
Published: June 2019

SiO2-doped Na+-β/β″-Al2O3 was synthesized via a solid-state reaction, and the relationship between the SiO2 content and properties of Na+-β/β″-Al2O3 was investigated. Respective specimens were doped with 0 – 5 wt.% SiO2 as a liquid phase sintering promotor and sintered. The specimens were characterized by XRD, SEM, densimeter and impedance analyzer. In the sintered samples, the phase fraction of β″-Al2O3 decreased as the SiO2 content increased, whereas the relative sintered density was enhanced with the inclusion of less than 0.7 wt.% SiO2. The relative sintered density of Na+- β/β″-Al2O3 sintered specimen with 0.7 wt.% SiO2 doping reached 99.2 % of the theoretical density and the sintered density decreased when the amount of SiO2 was larger than 1 wt.% result from excessive liquid-phase formation during sintering. Similarly, the ionic conductivity of SiO2-doped Na+-β/β″-Al2O3 was enhanced by doping with a small amount of SiO2, whereas the addition of more than 1 wt.% SiO2 negatively affected the ionic conductivity of Na+-β/β″-Al2O3 due to a decrease in the sintered density and unfavorable phase relationship.

Published: June 2019

The paper reports the use the sol-gel auto-combustion method for the preparation of nanocrystalline La1-xSrxFeO3 (x = 0¸0.7). The physical and chemical properties, microstructure, morphology and magnetic properties of the particles thus formed were studied. The X-ray diffraction (XRD) results indicated that Sr2+ instead of perovskite La are attributed to the lattice forming solid solution La1-xSrxFeO3, which has single orthogonal perovskite structure, space group Pnma, and does not show any impurity peaks. Fourier-transform infrared (FT-IR) spectroscopy confirmed the presence of Fe-O-Fe bond antisymmetric stretching vibration of FeO6 regular octahedron. The scanning electron microscope (SEM) analysis showed that introduction of Sr2+ ions can inhibit the growth of size of the particles thereby forming particles with spherical shape and better dispersion properties. The magnetic properties of the sample showed that with increase in Sr2+ ion concentration leads to increase in sample’s magnetism. DOI: http://dx.doi.org/10.5755/j01.ms.25.3.19455
Influence of Drying Temperature on Tensile and Bursting Strength of Bacterial Cellulose Biofilm
Authors: SEDERAVIČIŪTĖ Florentina , DOMSKIENĖ Jurgita , BALTINA Ilze
Published: June 2019

The article presents an experimental study of mechanical properties of cellulose biofilm produced by bacterial fermentation process. Naturally derived biomaterial has great current and potential applications therefore the conditions of material preparation as well as control and prediction of mechanical properties is still a relevant issue. Bacterial cellulose was obtained as a secondary product from Kombucha drink. Presented technique for material preparation and drying is particularly simple and easy to access. The influence of drying temperature (25 °C, 50 °C and 75 °C) on the sample size (thickness and planar dimensions) and mechanical properties (tensile and bursting strength) of cellulose biofilm has been evaluated. It was estimated that during drying biofilm specimens lost up to 92 % of weight and up to 87 % of thickness therefore planar specimen dimensions varied insignificantly. The study showed that the drying temperature is important for optimum strength properties of bacterial cellulose biofilm. The maximum tensile strength (27.91 MPa) was recorded for the samples dried at temperature of 25 °C, when the moisture from the biomaterial is removed gradually and good deformation properties are ensured (respectively tensile extension 18.8 %). Under higher drying temperature biomaterial shows lower values of tensile strength and higher values of bursting strength. The maximum bursting strength (57.2 MPa) was recorded for samples dried at 75 °C when punch displacement changes were insignificant for all tested samples (from 17.8 mm to 21.7 mm).

Published: June 2019

Topotactic transformation was one of the most frequently related processes in the synthesis process of cobalt oxide nanomaterials. Microstructural evolution studies of this process inform and enable the process of controlling the shape of the final products. One such topotactic transformation was investigated here, the transition from Co(OH)2 hexagonal nano platelets to Co3O4 octahedra by a hydrothermal method in an ammonia solution. Evolution of phase and microstructure was studied during different stages of the reaction to reveal the criteria which prompt this transformation. A phase transformation from Co(OH)2 to CoOOH and hence to Co3O4 was observed. High resolution transmission electron microscopy and image simulation were utilised to disclose the role of defects in the topotactic transformation. A high density of defects including edge dislocations and displacements was found on the surface of dried Co(OH)2 nano platelets. The coexistence of CoOOH domains embedded in the Co(OH)2 surface indicates the absence of the hydrogen bonds of the starting materials. The breaking of hydrogen bonds leads to bonding variation and the further creation of defects, finally prompting the transformation from Co(OH)2 to CoOOH. The breaking of hexagonally arranged hydrogen bonds creates seeds for the formation of Co3O4. DOI: http://dx.doi.org/10.5755/j01.ms.25.3.22005
Sleep Disorder at High Altitude
Authors: Kong Fanyi
Published: June 2019

In this chapter, we discuss the occurrence, mechanism, clinical manifestations, outcomes, and managements of a commonly encountered sleep disorder of someone traveling in high altitude for working and sight-seeing. Humans ascending to altitudes above 2500 m usually suffer from substantial disturbances in sleep quality as difficulty in sleep onset, frequent awakenings, respiratory disturbance, and a feeling of drowsiness on the next day. Data obtained from polysomnographic studies demonstrated several variations of sleep architecture in those healthy subjects ascending to high altitude during sleep, including periodic breathing and decreased non-rapid eye movement deep sleep stage 3 and 4 (in new nomenclature N3), which were usually accompanied by and the lowered arterial O2 and restricted ventilation. Hypoxia is most severe during sleep and in correspondence to periodic breathing and sleep disturbance at high altitude. Poor sleep quality impairs cognition and executive abilities at high altitude though it may largely be improved after full time of acclimatization. Evidence-based choices for clinicians to treat sleep disorder at high altitude are relatively scarce at present. Supplemental oxygen and dietary nitrate are effective in alleviating nocturnal hypoxia. There is strong evidence supporting the efficacy and safety of acetazolamide and nonbenzodiazepines in minimizing periodic breathing and improving sleep quality at high altitude.
Lack and Excess / Zero and One
Authors: Finkelde Dominik ,   DePaul University
Published: June 2019

How can a set throw itself into itself and remain a set and an element of itself at the same time? This is obviously impossible, as Bertrand Russell has prominently shown. One simply cannot pick a trash can up and throw it into itself. Now, Hegel and Badiou, but also the anti-Hegelian W. Benjamin, take different positions on the subject when they refer time and again to versions of “concrete universality” as an oxymoronic structure that touches ontologically upon their theoretical as well as their practical philosophies. The article tries to show how the philosophers affirm the mentioned paradox as central for the understanding of Dialectical Materialism in its classical (nineteenth-century) as well as in its modern (twentieth-century) and contemporary (twenty-first-century) understanding.
Políticas do esquecimento: trauma e fantasmagoria nas culturas brasileira e portuguesa
Authors: Vasconcellos Lisa Carvalho
Published: June 2019

A escassa produção de textos – literários ou não – sobre a Colônia Correcional da Ilha Grande, no Brasil, e o campo de prisioneiros de Tarrafal, na África portuguesa, dois importantes centros de detenção política, pode ser tomada como um índice das dificuldades enfrentadas pelas culturas desses países na elaboração das práticas autoritárias às quais ambos foram submetidos ao longo de quase todo o século XX.  Escritos sob o influxo da dor e do trauma, mas também do interdito e do recalque (cf. FREUD, 2010), muitos dos testemunhos, dos depoimentos e dos textos ficcionais (memorialísticos e autobiográficos em sua maioria) que procuraram pensar tais assuntos estão marcados pelo silenciamento de conflitos e pela denegação – novamente em sentido freudiano – da violência experienciada. Nesse sentido – e conforme propõem Roberto Vecchi e Margarida Calafate Ribeiro (cf. RIBEIRO & VECCHI, 2011) no que diz respeito à memória poética da Guerra Colonial lusa – os conceitos de fantasmagoria, rastro e resto propostos por Walter Benjamin podem funcionar como provocação teórica para o entendimento dos textos literários e da cultura letrada desses países (assim como das práticas políticas que lhe servem de horizonte). No trabalho que ora propomos, o objetivo será estudar comparativamente os livros Memórias do cárcere (1953), de Graciliano Ramos e Tarrafal, o pântano da morte, de Cândido de Oliveira, procurando ver como ambas as obras – ao mesmo tempo em que se reconhecem assombradas pelos fantasmas do silenciamento e da repressão – decidem enfrentá-los, usando o próprio texto como arma e mediação.
O autoritarismo e a violência em O rei branco, de György Dragomán
Authors: Lazzaretti Jildonei , Martins Adriana Claudia
Published: June 2019

Este artigo consiste em uma análise da obra O rei branco, de György Dragomán, a partir dos conceitos de autoritarismo e de violência, a fim de constatar como a narrativa se desenvolve em relação a essas duas temáticas. Nesse sentido, são consideradas as definições de “autoritarismo” e “violência” presentes no Dicionário de Política, de Bobbio el al. (1998), bem como a  reflexão teórica e alegórica de Wolfgang Sofsky no Tratado sobre la violencia (2006). Além disso, são também analisadas as referências históricas utilizadas na construção ficcional da narrativa, a fim de compreender as especificidades do regime autoritário e violento mencionado na obra. Desta forma, a presente análise demonstra a centralidade dos conceitos de autoritarismo e de violência em O rei branco, sendo determinantes, não apenas para o desenvolvimento do enredo, como também para a transformação do narrador-personagem: Dzsátá.

Nos últimos quinze anos, a população carcerária do país praticamente triplicou. Asrevoltas e os massacres que atingiam São Paulo se espalharam e hoje se dão em capitais menores, como Boa Vista e Fortaleza. De fato, estamos mergulhados numa crise ampla e generalizada, cujas proporções não conhecemos. Pois, diferentemente de outras “pautas”, esta não tem ganhado a percepção social que julgamos merecer, na grande imprensa, na grande política. Nesse contexto, consideramos fundamental refletir e elaborar o nosso passado prisional a partir, sobretudo, do nosso campo de estudo: a produção literária e cultural.

Agression en milieu psychiatrique fermé : identification des déclencheurs qui précèdent les agressions contre les intervenants
Authors: Groleau Robert , Da Silva Guerreiro Joao
Published: June 2019

Cette étude vise l’identification des déclencheurs qui précèdent les agressions survenues dans un hôpital psychiatrique fermé. Une analyse de contenu de 140 rapports d’incident visant l’identification du déclencheur qui précédait immédiatement les événements d’agression survenus entre 2012 et 2017 a été effectuée. Avec un accord interjuge de 0,87, les résultats concordent avec ceux retrouvés dans des études précédentes. Plus de 37 % des agressions surviennent à la suite d’une intervention verbale d’un intervenant, alors qu’un peu plus de 54 % ont lieu à la suite d’un contact physique entre un intervenant et un patient. Moins de 9 % des agressions subies par le personnel sont liées à des événements où il a été impossible d’observer un déclencheur. Ces résultats sont discutés dans le cadre d’une approche interactionnelle sur l’agression en psychiatrie légale et ils permettent de proposer des pistes pour réduire le risque d’agression.
On the Challenges of Transnational Feminist Translation Studies
Authors: Flotow Luise von
Published: June 2019

The term “transnational” developed over the 20th century to describe cosmopolitan, multicultural societies that stem from migration; the concept of transnational feminist translation studies adds references to postcolonial feminisms to this term, offering new collaborative avenues of research and publication. This article reports on the challenges such collaborations pose, and how they have impacted an early attempt to produce an anthology of scholarly texts in the area of transnational feminist translation studies (Flotow and Farahzad, 2017). It develops a number of specific areas of difficulty: the “hegemony” of English in academic publishing and how this affects the circulation of feminist texts from beyond the Anglo-American Eurozone; the issue of power relations between editors and authors, cultures, and languages; questions of inclusion and exclusion, especially as different religious/cultural backgrounds affect scholarly discussion; and the importance of women’s/feminist diversity as well as the risks/benefits of a universalizing discourse. While the article is concerned with “challenges”, it ends with a call for more such collaborative transnational work to re-energize and promote the field of feminist translation studies worldwide.

The mammalian auditory sensory epithelium has one of the most stereotyped cellular patterns known in vertebrates. Mechano-sensory hair cells are arranged in precise rows, with one row of inner and three rows of outer hair cells spanning the length of the spiral-shaped sensory epithelium. Aiding such precise cellular patterning, differentiation of the auditory sensory epithelium is precisely timed and follows a steep longitudinal gradient. The molecular signals that promote auditory sensory differentiation and instruct its graded pattern are largely unknown. Here, we identify Activin A and its antagonist follistatin as key regulators of hair cell differentiation and show, using mouse genetic approaches, that a local gradient of Activin A signaling within the auditory sensory epithelium times the longitudinal gradient of hair cell differentiation. Furthermore, we provide evidence that Activin-type signaling regulates a radial gradient of terminal mitosis within the auditory sensory epithelium, which constitutes a novel mechanism for limiting the number of inner hair cells being produced.

Background

The Star Excursion Balance Test (SEBT) is commonly used to assess dynamic postural balance both in clinical practice and research. The aim of our study was to assess the within-session relative and absolute reliability of participants’ performance of the modified SEBT (mSEBT) using a single practice trial in healthy elite athletes who were familiar with the test.

Methods

An intra-session repeated-measures design was used to investigate the relative and absolute reliability of participants’ (healthy athletes partaking in sports at a high-risk of ankle sprain injury) performance of the mSEBT. A total of 122 healthy elite athletes from soccer (n = 73), basketball (n = 15), and volleyball (n = 34) performed one practice trial and three test trials within one session, in three directions (anterior, postero-medial, and postero-lateral), for both legs. Intraclass correlation coefficient (ICC), standard error of measurement (SEM), and smallest detectable change at a 95% confidence were calculated.

Results

We found a good to excellent relative within-session intra-rater reliability between the three trials on specified directions, with an ICC (3,1) from 0.90 to 0.95. SEM and SDC95 for normalized and composite scores, for both legs ranged from 0.91 to 2.86, and 2.54 to 7.94, respectively.

Conclusions

In conclusion, we report good to excellent within-session reliability for the mSEBT. Our results confirm that the test can be reliably used with only one practice trial in healthy elite athletes familiar with the test.

An experiment was carried out to evaluate the effect of increased temperature on roots and leaf water and osmotic potential, osmotic adjustment (OA) and transpiration on Triticum durum L. (CIRNO C2008 variety) during growth (seedling growth), tillering and heading phenophases. Wheat was sown under field conditions at the Experimental Technology Transfer Center (CETT-910), as a representative wheat crop area from the Yaqui Valley, Sonora México. Thermal radiators were placed at 1.20 m from the crop canopy. Treatments included warmed plots (2 °C) and ambient canopy temperature with five replicates. Temperature treatment was controlled using a (proportional, integrative, derivative) feedback control system on plots covering a circular area of r = 1.5 m. Results indicated a significant decrease in the osmotic potential of roots and leaves for the warmed plots. Water potential, under warming treatment, also experienced a significant reduction and a potential gradient was observed in both, roots and leaves, while the phenophases were delayed. Such results demonstrate that, under warmer conditions, plants increase water absorption for cooling. Hence, transpiration experienced a significant increase under warming in all phenophases that was related to the low root and leaf water potential. CIRNO C2008 also experienced OA in all phenophases with glycine betaine as the osmolyte with major contribution.

Published: June 2019

Dehydration-responsive element-binding factor 2 (DREB2) belongs to the C-repeat-binding factor (CBF)/DREB subfamily of proteins. In this study, a 2,245 bp PsDREB2 promoter fragment was isolated from the genome of Paeonia suffruticosa. The fragment was rich in A/T bases and contained TATA box sequences, abscisic acid (ABA)-response elements, and other cis-elements, such as MYB and CAAT box. The promoter was fused with the β-glucuronidase (GUS) reporter gene to generate an expression vector. Arabidopsis thaliana was transformed with a flower dipping method. Gus activity in different tissues and organs of transgenic plants was determined via histochemical staining and quantified via GUS fluorescence. The activity of promoter regulatory elements in transgenic plants under drought, low-temperature, high-salt, and ABA stresses was analyzed. The results showed that the PsDREB2 gene promoter was expressed in the roots, stems, leaves, flowers, and silique pods but not in the seeds of transgenic Arabidopsis. Furthermore, the promoter was induced by drought, low temperature, high salt, and ABA. Hence, the PsDREB2 promoter is tissue- and stress-specific and can be used in the genetic engineering of novel peony cultivars in the future.
Bioinformatic pipelines for whole transcriptome sequencing data exploitation in leukemia patients with complex structural variants

Published: June 2019

Background

Extensive genome rearrangements, known as chromothripsis, have been recently identified in several cancer types. Chromothripsis leads to complex structural variants (cSVs) causing aberrant gene expression and the formation of de novo fusion genes, which can trigger cancer development, or worsen its clinical course. The functional impact of cSVs can be studied at the RNA level using whole transcriptome sequencing (total RNA-Seq). It represents a powerful tool for discovering, profiling, and quantifying changes of gene expression in the overall genomic context. However, bioinformatic analysis of transcriptomic data, especially in cases with cSVs, is a complex and challenging task, and the development of proper bioinformatic tools for transcriptome studies is necessary.

Methods

We designed a bioinformatic workflow for the analysis of total RNA-Seq data consisting of two separate parts (pipelines): The first pipeline incorporates a statistical solution for differential gene expression analysis in a biologically heterogeneous sample set. We utilized results from transcriptomic arrays which were carried out in parallel to increase the precision of the analysis. The second pipeline is used for the identification of de novo fusion genes. Special attention was given to the filtering of false positives (FPs), which was achieved through consensus fusion calling with several fusion gene callers. We applied the workflow to the data obtained from ten patients with chronic lymphocytic leukemia (CLL) to describe the consequences of their cSVs in detail. The fusion genes identified by our pipeline were correlated with genomic break-points detected by genomic arrays.

Results

We set up a novel solution for differential gene expression analysis of individual samples and de novo fusion gene detection from total RNA-Seq data. The results of the differential gene expression analysis were concordant with results obtained by transcriptomic arrays, which demonstrates the analytical capabilities of our method. We also showed that the consensus fusion gene detection approach was able to identify true positives (TPs) efficiently. Detected coordinates of fusion gene junctions were in concordance with genomic breakpoints assessed using genomic arrays.

Discussion

Byapplying our methods to real clinical samples, we proved that our approach for total RNA-Seq data analysis generates results consistent with other genomic analytical techniques. The data obtained by our analyses provided clues for the study of the biological consequences of cSVs with far-reaching implications for clinical outcome and management of cancer patients. The bioinformatic workflow is also widely applicable for addressing other research questions in different contexts, for which transcriptomic data are generated.
SOME COMMENTS ON COASTAL ENGINEERING
Authors: O'Brien M.P.
Published: June 2019

The Canadian Organizing Committee, the Vancouver Executive Committee and the National Research Council of Canada have done a superb job in planning this conference and in carrying out the enormous amount of detail necessary for its realization. On behalf of the Coastal Engineering Research Council, the other participating organizations, and all of the attendees I thank most heartily all who participated in this work. I am personally most grateful to those representatives of the Canadian Committee who made the final selection of papers. I should explain at this point that a small papers Committee is appointed for each of these conferences to review the summaries submitted by the authors - but this screening is intended only to appraise their appropriateness for a coastal engineering audience - and to eliminate those few papers which are promotional "blurbs". It has not been a technical review such as is made for "refereed" technical and scientific journals. The number of papers submitted for this Conference passing this simple review far exceeded the reasonable limits of the program - and for a brief period the Papers Committee faced the new and distasteful task of selection among papers acceptable under past standards. However, the problem was handled by the Canadian Committee - applying a formula which seemed equitable and reasonable. I trust that those affected concur in this judgment.
CONFIDENCE INTERVALS FOR OCEAN WAVE SPECTRA
Authors: Borgman Leon E.
Published: June 2019

The random nature of ocean wave records introduces statistical variability into the wave spectrum estimates based on these records. This may cause inaccuracy in subsequent calculations such as the prediction of the primary wave direction or the estimation of structural response. Confidence intervals on such estimates are needed to evaluate whether adequate estimate accuracy has been obtained. The chi-squared confidence interval commonly used for wave spectra is based on the assumption of a Gaussian sea surface. Its applicability for hurrican size waves has been open for question. Therefore, after a brief outline of the relevant statistical relations basic to the chi-squared procedure, wave data from Hurrican Carla is empirically analyzed and compared with the theoretical conclusions. A simulation procedure is used to proceed from the data to probability interval statements. A comparison of these with the correponding chi-squared statements shows the chi-squared relations to be fairly reasonable approximations for spectral estimates averaged over bands of at least eight values. The empirical simulation procedure can be extended to subsequent calculations based on the spectral estimates while the chi-square method encounters difficulty for such problems.
REFLECTION AND TRANSMISSION FOR A POROUS STRUCTURE
Authors: Kondo Hideo , Toma Satoshi
Published: June 2019

Effects of characteristics of incident waves and of the thickenss of structure on wave reflection by and transmission through a porous structure were studied. Use of an idealized porous structure which is a lattice composed of circular cylinders was made. The relative thickness of structure B/L was found to have appreciable effects on reflected and transmitted wave energies. The reflection coefficient Kr reaches to a maximum of it for B/L of about 0.2 to 0.25, then decreases as B/L increases, and remains approximately uniform for B/L larger than about 0.6. The transmission coefficient Kt, however, decreases nearly exponentially as B/L increases. Measurement of wave height within structure revealed a Dattern of standing waves having a loop at the front face and a node at the rear face of it. That relates to the trend of Kr. Analytical approaches to predict the transmitted wave height, and wave heights before and within porous structures are found to be useful.
