Frequency-dependent amplification of the Sanriku tsunamis in Ryori Bay
Authors: Yamanaka Yusuke , Nakamura Miyuki
Published: January 2020

In the present study, the local tsunami amplification observed in Ryori Bay, located on the Sanriku coast of Japan, was investigated using numerical simulations. Large-scale tsunami propagation simulations and tsunami inundation simulations for the bay were systematically conducted to estimate and model the 2011, 1933, and 1896 tsunamis that occurred off the Sanriku coast and which resulted in large run-ups. The simulation results, which are moderately consistent with observations, presented larger run-up heights and inundations for the 1933 and 1896 tsunamis (which followed relatively small earthquakes) compared to those of the 2011 tsunami (which followed a larger earthquake). Furthermore, the frequency analysis indicated that the former two tsunamis comprised higher predominant components. A tsunami inundation simulation using parametrized synthetic waveforms was conducted to identify the contributing factors associated with the large amplification and run-ups. The results indicated that the predominant components are significantly amplified in the bay and the initial decrease in the water surface elevation prior to the primary waves of the two tsunamis leads to an increase in their run-up heights. Furthermore, the simulated waveforms of the tsunamis revealed that the 1933 and 1896 tsunamis had their wavefronts changed into a steep wavefront, i.e., a bore-like wave, during their wave developments in the bay, attributed to shoaling, narrowing bay width, and the nonlinear effect of the wave. These results, therefore, indicate that bores which are known to generate large run-up heights were generated in the bay during the two tsunamis.
Tri-trophic interactions among nitrogen-fertilized tomato cultivars, the tomato fruit worm, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) and the ectoparasitoid, Habrobracon hebetor (Say) (Hymenoptera: Braconidae)

Published: January 2020

Nitrogen is one of the most critical elements for plant and herbivore growth. This research aimed to investigate the bottom-up effect of varying nitrogen fertilization on the demography of the ectoparasitoid,Habrobracon hebetor(Say) on the tomato fruit worm,Helicoverpa armigera(Hübner) reared under different host-plant treatments. Six tomato plant cultivars (e.g., Kingston, Riogrand, Earlyurbana, Redston, Superstrain-B, and Primoearly and 4 N-fertilization levels (0, 2.1, 3.0, 3.9 g/pot nitrogen as urea 46%) were tested, using 5th instar larvae ofH. armigeraparasitised byH. hebetorunder laboratory conditions. The mortality rate and developmental time of the immature stages of the parasitoid, as well as adult longevity and fecundity, were recorded. Data were analyzed based on age-stage two-sex life-table theory. The results showed that the developmental duration of the parasitoids was affected by the increase in the levels of nitrogen. The highest value was observed at 12.83 ± 0.11 days on Earlyurbana with the lowest nitrogen level. The lowest intrinsic rates of increase (r) and finite rates of increase (λ) were 0.1058 ± 0.0147 and 1.1013 ± 0.0157 day− 1, respectively, regarding the lowest (zero) level of added fertilizer. However, the highest rates were 0.1515 ± 0.018 and 1.1608 ± 0.013 day− 1, respectively. The fecundity and longevity of adult wasps were positively correlated with nitrogen levels. Accordingly, differences in host-plant quality can indirectly affect the performance of parasitoids via the herbivore.

Published: January 2020

Background

EpiFibro (Brazilian Epidemiological Study of Fibromyalgia) was created to study patients with fibromyalgia (FM). Patients were included since 2011 according to the classification criteria for FM of the American College of Rheumatology of 1990 (ACR1990).

Objective

To analyze the therapeutic measures prescribed by Brazilian physicians.

Materials and methods

Cross-sectional study of a multicenter cohort. The therapeutic measures were described using descriptive statistics.

Results

We analyzed 456 patients who had complete data in the registry. The mean age was 54.0 ± 11.9 years; 448 were women (98.2%). Almost all patients (98.4%) used medications, 62.7% received health education, and less than half reported practicing physical exercise; these modalities were often used in combination. Most patients who practiced exercises practiced aerobic exercise only, and a significant portion of patients combined it with flexibility exercises. The most commonly used medication was amitriptyline, followed by cyclobenzaprine, and a minority used medication specifically approved for FM, such as duloxetine and pregabalin, either alone or in combination. Combinations of two or three medications were observed, with the combination of fluoxetine and amitriptyline being the most frequent (18.8%).

Conclusion

In this evaluation of the care of patients with FM in Brazil, it was found that the majority of patients are treated with a combination of pharmacological measures. Non-pharmacological methods are underused, with aerobic exercise being the most commonly practiced exercise type. The most commonly prescribed single drug was amitriptyline, and the most commonly prescribed combination was fluoxetine and amitriptyline. Drugs specifically approved for FM are seldom prescribed.

Published: January 2020

The effects of ultrasound power on extraction kinetic model, and physicochemical and structural characteristics of collagen from chicken lung were studied. Ultrasound power caused a significant increase in extraction rate and equilibrium concentration, with the maximum extraction yield (31.25%) at 150 W. The experimental data were consistent with the predicted ones in this empirical equation, in which the percentage error differences was 0.026–4.159%. Besides, ultrasound treatment did not affect their triple-helical structure. The thermal stability of pepsin-soluble collagen by ultrasound pre-treatment (UPSC) was higher, due to the higher imino acid content (20.76%). UPSC also exhibited better solubility and fibril forming capacity. Overall, the kinetic model of UPSC from chicken lung could serve the purpose of obtaining collagen, which displayed a potential alternative source to mammal collagens for application in food, biomaterials and biomedical fields.

Developing emulsion gels by incorporating Jerusalem artichoke inulin and investigating their lipid oxidative stability
Authors: Li Feijie , Gunenc Aynur , Hosseinian Farah
Published: January 2020

This study investigated physical, chemical and lipid oxidative properties of emulsion gels (W/O) incorporating Jerusalem artichoke (JA) inulin. Primary purified inulin extract (PPIE, 1%) improved the homogeneity of emulsion gel (with no syneresis) and developed smaller particle size droplets (average 40 μm) than control (average size 60 μm). HPLC revealed that PPIE had 80.28% inulin content compared with commercial inulin (CI, 100%). Crude inulin extract (CIE, 0.08–0.33 mg/mL) delayed linoleic acid oxidation because of higher total phenolic content (4.96 ± 0.01, mg GAE/g), compared with PPIE (0.72 ± 0.03). Lipid oxidative stability of emulsion gels with inulin samples was in the order of CI > PPIE > CIE (P < 0.05) by Rancimat analysis, which agreed with volumetric gel index results. This study suggests that emulsion gels with JA inulin (PPIE) could act as a potential fat replacement in food systems.

Authors: Elamragy Ahmed Adel , Meshaal Marwa Sayed , El-Kholy Amani Ali , Rizk Hussein Hassan
Published: January 2020

Background

No data exists about the gender differences among patients with infective endocarditis (IE) in Egypt. The objective was to study possible gender differences in clinical profiles and outcomes of patients in the IE registry of a tertiary care center over 11 years.

Results

The IE registry included 398 patients with a median age of 30 years (interquartile range, 15 years); 61.1% were males. Males were significantly older than females. Malignancy and recent culprit procedures were more common in females while chronic liver disease and intravenous drug abuse (IVDU) were more in males. IE on top of structurally normal hearts was significantly more in males (25.6% vs 13.6%,p= 0.005) while rheumatic valvular disease was more common in females (46.3% vs 29.9%,p= 0.001). There was no difference in the duration of illness before presentation to our institution. The overall complication rate was high but significantly higher in females. However, there were no significant differences in the major complications: mortality, fulminant sepsis, renal failure requiring dialysis, heart failure class III–IV, or major cerebrovascular emboli.

Conclusion

In this registry, IE occurred predominantly in males. Females were significantly younger at presentation. History of recent culprit procedures was more common in females while IVDU was more common in males who had a higher incidence of IE on structurally normal hearts. The overall complication rate was higher in women. IE management and its outcomes were similar in both genders.
Local growth charts for an Iranian child population aged 2–5 years in comparison with the World Health Organization Child Growth Standards
Authors: Heidari Zahra , Feizi Awat , Rezaei Sara , Kelishadi Roya
Published: January 2020

Background

There are no national reference charts in Iran for children aged under five. This study aimed to develop representative growth reference charts of height, weight, and BMI for children aged 2–5 years in Isfahan, Iran, and to compare them with the WHO reference curves.

Results

This population-based study has a combination of longitudinal and cross-sectional design. It included 1325 and 761 healthy children, who were born between 2002 and 2015 in Isfahan, central Iran, in longitudinal and cross-sectional phases. Expert health care providers measured the height and weight of children in health centers. The lambda-mu-sigma method was used to construct the age- and sex-specific growth charts of anthropometric measures. The study sample comprised 1029 boys and 1057 girls. The centiles of height, weight, and BMI of boys were higher than that of girls in all age groups. The weight patterns of studied children were close to those of the WHO references in the lower percentiles. However, our study children, especially girls, were lighter compared with WHO standards based on the middle and upper percentiles of the weight distribution. Compared with WHO standards, boys of our study were taller especially at older ages. The percentiles of the BMI for our study samples were considerably lower than WHO standards.

Conclusion

There are differences between our local growth charts for weight, height, and BMI with WHO standards. The local growth standards could be more precise for assessing growth problems in local and national settings. Due to notable differences between our results with WHO standards, future studies are warranted for constructing nationwide growth charts.
A support vector regression approach to predict geotechnical properties of soils from electrical spectra based on Jonscher parameterization
Authors: Boadu Fred Kofi
Published: January 2020

Electrical-conductivity spectra of soils contain valuable information about their texture, structure, and composition that can be linked to their geotechnical properties. Concurrent measurements of electrical spectra in the frequency range of 0.01 Hz to 10 kHz and geotechnical properties, that is, the dry unit weight [Formula: see text], modulus of elasticity [Formula: see text], and the hydraulic conductivity [Formula: see text], are performed on natural soil samples in a laboratory environment. The electrical spectra are modeled with the Jonscher fractal power law model characterized by three parameters: DC conductivity [Formula: see text], transition frequency [Formula: see text], and an exponent [Formula: see text]. We explore a machine-learning technique, the support vector regression (SVR) methodology, to model and predict the geotechnical properties from the Jonscher parameters, and we compare our results with the predictions of multiple linear regression (MLR). For model training and testing, the Jonscher parameters are used as the input, and a geotechnical parameter is used as the output. Model comparisons indicate that the developed SVR models predict [Formula: see text] with an [Formula: see text], predict [Formula: see text] with [Formula: see text], and predict [Formula: see text] with [Formula: see text]. In comparison, MLR models predict [Formula: see text] with an [Formula: see text], [Formula: see text] with [Formula: see text], and [Formula: see text] with [Formula: see text]. The results illustrate that the SVR models are more accurate, reliable, and achieve better performance for predicting the geotechnical properties from the electrical parameters in comparison to the predictions of the MLR models. Our study offers an opportunity in our quest in using noninvasive electrical geophysical methods to obtain geotechnical properties of soils, and it has broad implications in engineering geophysics.
Realistic weather conditions and removal of time-varying sea-surface effects: Application on ocean-bottom-cable data
Authors: Cecconello Elsa , Söllner Walter
Published: January 2020

In marine seismic acquisition, seismic reflections at the sea surface, such as sea-surface ghosts and multiples, affect the accuracy of the retrieved subsurface reflections and reduce the usable frequency bandwidth. These sea-surface effects tend to increase with the increasing roughness of the weather conditions. Consequently, processing techniques that neglect the roughness and time variation of the sea surface induce errors in the data that could compromise the validity of the final images and interpretations. We study the impact of time-varying rough sea surfaces using a modeling method derived from the Rayleigh reciprocity theorem for time-varying surfaces, and we analyze errors in the source-deghosting operation. We show that the source-deghosting limitations are weather dependent for data including sea-surface multiples: For calm sea states (wave heights below 1.25 m), the error made by the source-deghosting process is negligible; however, for rough seas (wave heights above 1.5 m), it becomes significant and blurs the deghosted image at the sea-surface multiple signals. To accurately remove all sea-surface effects from the seismic data, we simultaneously apply source-deghosting and multiple-removal operations to the same up-going wavefield. This procedure is shown to be weather independent based on our theoretical derivation and the synthetic results. Finally, this is tested on a 2D OBC data set. Comparing the proposed inversion to up-down deconvolution, we observe similar features in both wavefields: Source ghosts and sea-surface multiples seem to have been correctly removed from the data, and the inverted result indicates a slightly better resolution for deeper reflections.
The choice and definition of summary measure for meta-analysis of clinical studies with binary outcomes: effect on clinical interpretation
Authors: Plumb Andrew A , Halligan Steve , Mallett Susan
Published: January 2020

Many systematic reviews and meta-analyses concern the effect of a healthcare intervention on a binary outcome i.e. occurrence (or not) of a particular event. Usually, the overall effect, pooled across all studies included in the meta-analysis, is summarised using the odds ratio (OR) or the relative risk (RR). Under most circumstances, it is obvious how to identify what should be considered as the event of interest—for example, death or a clinically important side-effect. However, on occasion it may not be clear in which “direction” the event should be specified—such as attendance (vs non-attendance) at cancer screening. Usually, this choice is not critical to the overall conclusion of the meta-analysis, but occasionally it can lead to differences in how the included studies are pooled, ultimately affecting the overall meta-analytic result, particularly when using RRs rather than ORs. In this commentary, we will explain this phenomenon in more detail using examples from the literature, and explore how analysts and readers can avoid some potential pitfalls.
Single-cell analyses uncover granularity of muscle stem cells
Authors: Saber John , Lin Alexander Y.T. , Rudnicki Michael A.
Published: January 2020

Satellite cells are the main muscle-resident cells responsible for muscle regeneration. Much research has described this population as being heterogeneous, but little is known about the different roles each subpopulation plays. Recent advances in the field have utilized the power of single-cell analysis to better describe and functionally characterize subpopulations of satellite cells as well as other cell groups comprising the muscle tissue. Furthermore, emerging technologies are opening the door to answering as-yet-unresolved questions pertaining to satellite cell heterogeneity and cell fate decisions.

OS EFEITOS DO MÉTODO PILATES NA FUNCIONALIDADE DO ASSOALHO PÉLVICO FEMININO E NA INCONTINÊNCIA URINÁRIA: UMA REVISÃO SISTEMÁTICA
Authors: Couto Ana Paula Jardim Pires do , Toigo Adriana Marques
Published: January 2020

Introdução: É a musculatura do assoalho pélvico (MAP) que sustenta a uretra e a bexiga, que se contrai durante o esforço de forma a prevenir a perda urinária. O enfraquecimento ou lesões nesta estrutura de suporte podem levar à sua disfuncionalidade. Segundo a Associação Internacional de Uroginecologia, a Incontinência Urinária (IU) é toda perda involuntária de urina. A IU pode ser classificada em 3 principais tipos: a Incontinência Urinária de Esforço (IUE) onde a perda involuntária de urina que ocorre durante a realização de como tossir, espirrar, levantar pesos, rir ou exercitar-se, Incontinência Urinária de Urgência (IUU), caracteriza-se por um desejo súbito e abrupto de urinar, difícil de ser inibido e a Incontinência Mista (IUM) que é a IUE somada à IUU. Embora a MAP não tenha sido enfatizada no trabalho original do Método Pilates (MP), algumas escolas têm integrado o foco na MAP em sua abordagem.  O objetivo deste estudo foi revisar achados anteriores quanto aos efeitos do MP na funcionalidade do assoalho pélvico feminino e na IU. Método: Foram selecionados e analisados artigos de periódicos arbitrados e estudos presentes em bancos de dados acadêmicos. Resultados: dez estudos foram selecionados para análise dos resultados. Os estudos abordaram o efeito do MP na funcionalidade do assoalho pélvico feminino e na IU. Conclusão: Observou-se que o MP trouxe resultados positivos na maioria das variáveis analisadas em 9 dos 10 estudos selecionados, porém mais estudos são necessários.

Volatile and permanent optical gratings recorded in Bi2TeO5photorefractive crystal under high cw intensity
Authors: de Oliveira I. , Capovilla D. A.
Published: January 2020

We report the recording of optical gratings on photorefractiveBi2TeO5crystals usingλ=532nmwavelength light. We studied the behavior of this material under high light intensity and found the presence of fast and slow gratings, both of photorefractive nature and exhibiting quite significant light intensity dependence for the1−13kW/m2range. A permanent grating was found after the complete erasure of fast and slow holograms recorded at room temperature. The experimental results show that the diffraction efficiency of the permanent grating increases with the recorded light intensity. The permanent grating performance as an optical Bragg filter was characterized by measuring the angular selectivity approximately 1.0 mrad. We also show that the diffraction efficiency of the permanent grating is quite dependent on the direction of light polarization.

Authors: Zhu Chengyu , Liang Lingxi , Yuan Hang , Zhou Luoxian , Li Yuxin , Wang Wenjie
Published: January 2020

In this study, stress wave and damage morphology on the rear surface of silica during laser induced damage with cumulative UV pump shots is investigated. Time resolved imaging system, along with stress induced birefringence detecting, is used to demonstrate the development of stress wave. The properties of three types of stress waves, namely, compressive wave (P-wave), shear wave (S-wave), and Rayleigh wave (R-wave) are recorded and studied during the damage process. The experimental and simulated results indicated that R-wave exhibits the highest intensity among all the three stress waves. Because the R-wave is mainly localized at the region near the surface, it is responsible for the mechanical damage along the surface; in addition, it rapidly increases the damage diameter, which was observed from the front view of the damage.

Super-resolved angular displacement estimation is of crucial significance to the field of quantum information processing. Here we report an estimation protocol based on a Sagnac interferometer fed by a coherent state carrying orbital angular momentum. In a lossless scenario, through the use of parity measurement, our protocol can achieve a 4ℓ-fold super-resolved output with quantum number ℓ; meanwhile, a shot-noise-limited sensitivity saturating the quantum Cramér-Rao bound is reachable. We also consider the effects of several realistic factors, including nonideal state preparation, photon loss, and inefficient measurement. Finally, with mean photon number

Published: January 2020

Terahertz time-domain spectroscopy measurements were performed on 0.7 mol% Mg-doped stoichiometric lithium niobate crystal with ordinary and extraordinary polarization in the 4-460 K temperature range. The absorption coefficient and refractive index spectra were recorded in the terahertz frequency range from 0.5 to 1.8 THz. The data extracted from the measurements are given in simple and concise form in order to provide easily usable practical information for those who would like to use this material in the terahertz range. Through a practical example it was also pointed out, that the effect of the temperature must not be neglected during the design and adjustment of terahertz sources if the goal is to maximize the optical-to-THz conversion efficiency.
Strategic planning of scientific research activities: What is the added value for Algerian research institutions?
Authors: Mezhouda Abdelmalik
Published: January 2020

Strategic planning becomes, nowadays, an integral part of higher education institutions management. It aims at supporting universities and colleges to anticipate changes, mobilize institutional energies and potentials around a shared vision and face new challenges. In spite of the well-acknowledged added value of strategic planning in higher education institutions worldwide, it still has not received enough attention within Algerian research institutions where traditional long-run planning is still prevailing. The present article aims at exploring the practice of research planning among Algerian research institutions focusing on its main elements, namely planning model, setting research priorities, alignment of objectives, research project planning, criteria of validating research projects, researchers' motivations and research projects monitoring. The article also highlights the potential value that strategic planning can deliver to help Algerian research institutions improve their performance and achieve their goals.

Encontramos un nuevo método de creación coreográfica presentado por Juan José Linares Martiañez (1933-2009), en Romance, basado en el respeto, conservación y mantenimiento de los elementos más esenciales que posee la danza tradicional popular. En este artículo se pretende extraer mediante el análisis de la composición coreográfica de Romance, las señas de identidad, y rasgos diferenciadores presentes en las danzas y bailes de la obra, para compararlos con las señas de identidad y rasgos diferenciadores que tienen las danzas y bailes tradicionales populares. Este trabajo analítico comparativo nos llevará al resultado aportado por Juanjo Linares, un nuevo lenguaje coreográfico: la danza tradicional escénica.
Wine, bread, and water, between doctrine and alternative. Norms and practical issues concerning the Eucharist and baptism in thirteenth-century Europe
Authors: Maraschi Andrea
Published: January 2020

Guillaume Durand’s Rationale divinorum officiorum was a liturgical encyclopedia which soon became the most important work of its kind, and thus represents an invaluable resource for the study of various aspects of liturgy and ritual in late thirteenth-century Europe. This contribution focuses on norms featured in the Rationale regarding two Christian sacraments - the Eucharist and baptism - for the they were held to originate from the same source (the wound on Christ’s side caused by the spear thrown by a Roman soldier). Both of these sacraments required elements for the administration (wine, water, bread) which had to meet specific characteristics, and this generated several issues, mainly concerning their availability and other practical issues. This study analyzes such characteristics and occasional proposals to replace the aforementioned elements by contextualizing Guillaume’s work within a wider intellectual and normative context, including Thomas Aquinas and earlier canon law. The intention is to show: 1) how fundamental a role normativity played in drawing the line between liturgy, heresy, and desecration; and 2) that normativity had to take practicality into account.
Os Conhecimentos do Budismo Sínico do Jesuíta Português Tomás Pereira
Authors: Zhang Minfen
Published: January 2020

O missionário jesuíta português Tomás Pereira entrou no império chinês durante o reinado de Kangxi (1662-1722) da dinastia Qing (1644-1912) com o fim de pregar a religião cristã. Viveu em Pequim durante 37 anos, dedicando quase toda a sua vida à causa cristã e à divulgação das ciências ocidentais na China. Como os seus predecessores Matteo Ricci e Álvaro Semedo, entre outros padres jesuítas, foi não só um missionário, mas também um observador, investigador e modelador da cultura chinesa. Como tal, é natural que tenha prestado um enorme interesse e atenção ao budismo, que foi introduzido na China durante as dinastias Han e já se tinha tornado uma das principais correntes religiosas da China. Pereira estudou e observou a cultura chinesa, tão heterogénea quanto o cristianismo, do ponto de vista de um sacerdote ocidental. O presente texto pretende fazer um estudo sobre a sua compreensão do budismo da China Qing baseando-se no seu Tratado do Budismo Sínico.

Published: January 2020

O presente estudo visa compreender como se processava o financiamento da universidade medieval portuguesa durante o século XIV, dando a conhecer a conflitualidade crescente entre o studium e a Igreja – conflitualidade essa relacionada com a alocação de rendas oriundas de diversos benefícios eclesiásticos, e que constituíam a principal fonte de sustento da universidade, desde a sua fundação nos últimos anos da centúria anterior. Além disso, procuraremos também analisar o impacto que as sucessivas deslocalizações do estudo geral entre as cidades de Lisboa e Coimbra tiveram na universidade medieval, com as consequentes alterações das igrejas designadas pela Coroa para o sustento dos lentes, mestres e do próprio studium, criando um foco de instabilidade e até de conflito na relação entre estas duas instituições de natureza eclesiástica – Igreja e universidade.
La formación gradual del pensamiento poético de Eduardo García
Authors: Mora Vicente Luis
Published: January 2020

El pensamiento poético de Eduardo García (São Paulo, Brasil, 1965) sufrió cambios y evoluciones a lo largo de los diferentes períodos de su vida, aunque un suelo común de diálogo entre irracionalismo poético y racionalismo filosófico puede detectarse con facilidad. En este artículo analizaremos la importancia de sus primeros trabajos teóricos y su libro sobre escritura creativa, Escribir un poema, para determinar su importancia en el ulterior desarrollo de su poética personal.

Published: January 2020

Los contenidos audiovisuales se han convertido en estrellas del contenido de consumo digital en la actualidad, especialmente de la mano de la eclosión de los social media. Las organizaciones que han dado el salto al nuevo paradigma comunicativo (más participativo y dialógico) buscan acercarse a sus públicos a través de los espacios y canales en los que se encuentran y por medio de una estrategia de contenidos que les ayude a posicionarse y relacionarse. El presente trabajo analiza el uso de vídeo/s en los dos medios sociales con mayor número de usuarios en España: Facebook y YouTube. El estudio de la gestión de dichos contenidos por parte de las empresas con mejor reputación (Reptrack 2017) ayudará a ofrecer resultados sobre tipologías, objetivos y grados de participación de sus públicos.
THE INFLUENCE OF LOW-TEMPERATURE PROCESSING OF CELLULOSE ON HEATS OF HYDRATION AND STRUCTURE CELLULOSE
Authors: Osovskaya Iraida Ivanovna , Antonova Veronika Sergeyevna
Published: January 2020

The urgency of the problem of modification of cellulose is dictated by the need to create the latest environmentally friendly technologies for processing cellulose using physical methods of exposure. The complex structure of crystalline and disordered zones, the presence of energetically-unequal system of hydrogen bonds largely determines the sorption, hydrophilic and paper-forming properties of cellulose composites. The method is developed of low-temperature processing of cellulose to create promising environmentally friendly technologies, in particular, for the production of fluff pulp and paper of low mechanical strength with high absorbency. The study of the freezing process of wet cellulose characterizes the behavior of cellulose as a high-molecular polymer with a mobile, plastic structure, easily changed under the influence of various factors. The dependence of the conditions of low-temperature treatment of cellulose on the absorption, hydrophilicity and structure of cellulose fiber is established from the standpoint of the thermodynamic method. Optimum conditions are revealed conditions of freezing wet cellulosic fibers to improve the hydrophilicity and ability formation of links of cellulose. The minimum water content under different conditions of low-temperature treatment of cellulose for the formation of water clusters and ice formation was established. The results of the density measurements by the gradient column method and the sorption of the direct green trisazo dye are consistent with the regularities found in the measurement of the enthalpy of wetting and sorption isotherms.

Three-dimensional (3D) body scanning is becoming an increasingly popular tool for research in the field of family and consumer sciences (FCS) because it quickly and accurately measures constructs that describe the human form. This study compared viewing a 3D body representation to viewing
a two-dimensional (2D) representation and whether the effects of these assessments varied by gender. College-student participants (N = 164, 63 women, 101 men) were randomly assigned to one of two different body image groups, a 3D image and a somatomorphic (2D) assessment of body shape.
Participants in both conditions completed a body-esteem pre-assessment, had their bodies scanned by a KX-16 body scanner, assessed the copy of their 3D or 2D body image, and then completed the body-esteem post-assessment. The 3D body scan group reported larger drops in body esteem than did
the 2D group from pretest to posttest. More specifically, women in the 3D condition reported a larger drop in body esteem from pretest to posttest compared to what the men reported. The results suggest that using a 3D body scanner could have negative short-term effects on body esteem.
Glory in the Memory of Men: Military Masculinities in the Mohawk Wars
Authors: Slater Sandra
Published: January 2020

Cet article explore les relations masculines entre Samuel de Champlain et ses alliés autochtones pendant la guerre avec les Agniers de 1609–1610. Cette alliance militaire permettait à Champlain et aux Indiens de faire preuve de leur masculinité en démontrant leur courage, bravoure et leurs prouesses sur le champs de bataille. Contestations et conformités entre eux suscitèrent des liens profonds qui allaient au-delà de la nécessité et de la courtoisie; il y avait entre eux un respect authentique et réciproque concernant leur identité en tant qu’hommes. Contrairement à ses prédécesseurs du 16ème siècle, Jean Ribault et René Laudonnière, dont les carences comme chefs finirent par affaiblir l’implantation des français en Floride, la population de la Nouvelle-France sous Champlain augmenta avec régularité du en grande partie aux alliances durables forgées avec les tribus des Grands-Lacs. Cet article juxtapose les deux tentatives de colonisations françaises et postule que les efforts de Champlain aboutirent car il savait s’adapter aux exigences masculines et à la creation de liens d’amitié de rigueur chez ses alliés, contrairement à ce que se passa en Floride. La guerre avec les Agniers, qui se limita à deux batailles en 1609–1619, fut l’occasion pour Champlain et les hommes Algonquins de démontrer ce que signifiait courage et virilité. La décision de Champlain de nouer une alliance avec les tribus des Grands-Lacs contre les Agniers (membre de la ligue des Iroquois) qui étaient perpétuellement belliqueux n’aboutit pas seulement à un respect mutuel, mais à une connaissance de valeurs masculines communes concernant la prouesse militaire et le courage. Les Indiens et Champlain connaissaient l’importance de démontrer une forte masculinité à la guerre. Champlain reconnaissait qu’il était crucial pour créer et conserver une alliance de faire une bonne prestation sur le champ de bataille et posséder un courage propre aux hommes. Cette similitude permet à Champlain et ses alliés de developer un plus grand sens d’égalité. Contrairement à Jean Ribault et René Laudonnière en Floride le siècle précédent, Champlain s’engageait avec enthousiasme dans les rites autochtones ce qui conduisit à la création d’amitiés chaleureuses. Ces rites masculins produisirent de la stabilité en Nouvelle-France et, au final, le succès de la colonie.
Assimilation, Association, and French Advice to Japan on How to Rule Taiwan
Authors: Hennessey John L.
Published: January 2020

Quels liens trans-impériaux ont existés entre l’empire colonial de la France et celui du Japon? Dans un exemple qui se raconte fréquemment dans l’historiographie coloniale japonaise, l’on discute du conseil que l’expert judiciaire français Michel Revon a présenté en 1895 quant au système administratif que le Japon devrait instaurer à Taiwan. Dans une note de politique, Revon aurait recommandé que l’on adopte un système français d’assimilation, ce qui aurait exercé une influence considérable sur le futur Premier ministre Hara Takashi. Cet article démontre que ce compte-rendu des faits n’est pas tout à fait exact et il présente donc une analyse nouvelle des sources primaires dans le contexte des théories françaises coloniales qui étaient dominantes pendant les années 1890. Nous avançons que Revon était en fait un partisan de l’association et que le programme d’assimilation coloniale de Hara Takashi n’était que superficiellement influencé par des modèles français.
Pensar (e fazer) de outras formas

Published: January 2020

Este número da Revista Letras & Letras constitui um Dossiê que, orientado por uma perspectiva Transdisciplinar, reúne textos de cientistas da linguagem, membros do GT Transculturalidade, Linguagem e Educação, filiado à Associação Nacional de Pós-Graduação e Pesquisa em Letras e Linguística (ANPOLL), que se propõem a discutir, problematizar e refletir sobre suas bases epistemológicas e a práxis em pesquisa, ensino e extensão. O sintagma Thinking (and doing) otherwise foi lançado como um convite aos membros para expor como têm mobilizado suas filiações teóricas, (re/des)territorializado e criado conceitos e agenciado as maneiras de fazer pesquisa. Os ecos teórico-políticos pós e decoloniais, críticos e anti-hegemônicos que resultaram do convite poderão ser lidos nos textos que abordam questões sobre educação linguística, políticas linguísticas, ensino de línguas e literatura, contextos multilíngues, linguagem e multimodalidade, letramento, tradução, migração e formação de professores. Os textos sugerem uma intelectualidade e um fazer acadêmico e educacional outro, compromissado com questões relacionadas à ética nas relações humanas, à visibilização de minorias sociais, ao questionamento constante das lógicas que determinam as identificações e representações de língua e saber.
(Des)alinhavando a(o)s ponta(o)s de contato epistemológicos entre os estudos da tradução e dos letramentos na pós-modernidade

Published: January 2020

Os estudos da tradução e dos letramentos são espectadores e, simultaneamente, protagonistas, das transições, crises e reformulações promovidas pela pós-modernidade. Um novo paradigma epistemológico surge, neste cenário, como uma necessidade de repensar o modelo de racionalidade tradicional das ciências, as quais mostravam sinais de exaustão (SOUSA SANTOS, 2008). Nosso objetivo é, assim, analisar possíveis pontos de contatos epistemológicos entre as teorias de tradução e as de letramentos, levando em consideração essa ruptura paradigmática pós-moderna. Nessa visada, partindo de uma perspectiva crítica dos estudos de letramentos (LANKSHEAR; KNOBEL, 2006), e contestadora (DERRIDA, 2001, 2002 2005) dos estudos da tradução, muitos pontos se entrecruzam na descontinuidade, na fragmentação e na diferença em que os sujeitos significam e traduzem, não apenas a palavra, mas o mundo, pelas lentes da alteridade, da heterogeneidade e da pluralidade.
