Effectiveness of Direct Application of Phosphate Rock in Upland Acid Inceptisols Soils on Available-P and Maize Yield
Authors: Nurjaya . , Nursyamsi Dedi
Published: August 2018

Source of P fertilizer which is used by farmers in upland acid soils area is generally acidulated phosphate rock (PR), such as tripel super phosphate (TSP), super phosphate 36% P2O5 (SP-36), as well as partial acidulated phosphate rock (PAPR) which contain 10-30% P2O5. Their effectiveness, however, varies and depends on the soil and plant types. Phosphate rock fertilizers have a high prospects for acid soils because its effectiveness equals to the SP-36, cheaper, slow release, and its application can also leave  the residual P in the soil that available for plants for next few seasons. Field experiment aimed to study the effectiveness of direct application of PR at upland acid soils and its effect on soil available-P as well as maize (Zea mays L.) yield was conducted in Acid Inceptisols of Ciampea, Bogor in wet season years 2008/2009. The experiment was arranged by a Randomized Completely Block Design with 3 replications. Maize of P-12 variety was used as a plant indicator. The treatment consisted of 6 levels of phosphate rock: 0, 20, 30, 40, 50, and 60 kg P ha-1, as well as one level of SP-36 40 kg P ha-1 as standard fertilizer. In addition, urea of 300 kg ha-1 and KCl of 100 kg ha-1 were used as basal fertilization. The result showed that the application of PR in the amount ranging from 20 to 60 kg P ha-1 increased total-P and available-P, and pH, decreased exchangeable Al in the soils as well as increased maize straw and grain. Phosphate rock  application at 40 kg P ha-1 level was equally effective as SP-36 in the tested soils. Critical level of soil P for maize grown in the soil was 675 and 5.00 mg P2O5 kg-1 extracted with HCl 25% and Bray I, respectively. The requirement of P for maize grown in the soil to achieve maximum profit was 38 kg P ha-1 and 17.5 kg P  ha-1 or equivalent to PR of 583 and 268 kg ha-1 in low (soil P < critical level) and high (soil P > critical level) soil P status,  respectively.Keywords: Direct application, phosphate rock, soil available-P, upland acid soils.[How to Cite: Nurjaya and D Nursyamsi. 2013.

Authors: Nurdin . , Zakaria Fauzan
Published: August 2018

The research aimed to study effect the application of river sand (RS), coconut coir (CC), and banana coir (BC) on growth and yield of rice (Oryza sativa L.) in Ustic Endoaquert. The research was carried out in a green house using 3 × 3 × 3 factorial design. The RS factor consists of three treatment levels which were 0% RS, 25% RS, and 50% RS. Meanwhile, the CC and BC consist of three treatment levels, where each level were 0 Mg ha-1, 10 Mg ha-1 and 20 Mg ha-1. The results showed that RS, CC and BC applications did not have significant effect on plant height. On the other hand, all ameliorant applications had significantly increase leaf length and the highest percentage increasing was in BC (13.49%). The leaf numbers and tiller numbers had relatively similar pattern, except BC that had significantly increased leaf numbers by 77.69% and amount of tiller numbers by 49.45%. Furthermore, for yield components, RS, CC and BC applications had significant increased panicle numbers by 37.76%. It was only RS and BC that increased panicle lenght and the best increasing of 26.82% on RS. Meanwhile, the BC application only increased the rice grain numbers.[How to Cite: Nurdin and F Zakaria. 2013.

Assessment Erosion 3D Hazard with USLE and Surfer Tool: A Case Study of Sumani Watershed in West Sumatra Indonesia
Authors: Aflizar . , Afrizal Roni , Masunaga Tsugiyuki
Published: August 2018

Quantitative evaluation of soil erosion rate is an important basic to investigate and improve land use system, which has not been sufficiently conducted in Indonesia.  The Universal Soil Loss Equation (USLE) and Erosion Three Dimension (E3D) in Surfer were used to identify characteristic of dominant erosion factors in Sumani Watershed in West Sumatra, Indonesia using data soil survey and monitoring sediment yield in outlet watershed.  Climatology data from three stations were used to calculate Rainfall erosivity (R) factor. As many as101 sampling sites were used to investigate soil erodibility (K-factor) with physico-chemical laboratory analysis. Digital elevation model (DEM) of Sumani Watershed was used to calculate slope length and Steepness (LS-factor). Landsat TM imagery and field survey were used to determine crop management (C-factor) and conservation practices (P-factor). Calculating soil loss and map of USLE factor were determined by Kriging method in Surfer 9. Sumani Watershed had erosion hazard in criteria as: severe to extreme severe (26.23%), moderate (24.59%) and very low to low (49.18%).  Annual average soil loss for Sumani watershed was 76.70 Mg ha-1 y-1 in 2011. Upland area was designated as having a severe to extreme severe erosion hazard compared to lowland which was designated  as having very less to moderate.  On the other land, soil eroded from upland were deposited in lowland. These results were verified by comparing one year’s sediment yield observation on the outlet of the watershed. Land use (C-factor), rainfall erosivity (R- factor), soil erodibility (K-factor), slope length and steepness (LS-factor) were dominant factors that affected soil erosion. Traditional soil conservation practices were applied by farmer for a long time such as terrace in Sawah.  The USLE model in Surfer was used to identify specific regions susceptible to soil erosion by water and was also applied to identify suitable sites to conduct soil conservation planning in Sumani Watershed.[How to Cite : Aflizar, R Afrizal, T Masunaga. 2013.

Oral Versus Written Recall of Long-Term Memory Items: Replicating and Extending the Writing Superiority Effect Across Knowledge Domains
Authors: Janczyk Markus , Aßmann Martin , Grabowski Joachim
Published: August 2018

Although language production offers a commonly used window into individuals’ knowledge, it remains questionable whether oral or written language production allows better diagnostic content validity, for example, in educational or legal settings. Existing results vary with respect to empirical evidence in favor of the oral or the written modality in knowledge assessment. However, for list-like organized knowledge domains (i.e., domains consisting of a definite number of uniform items), a writing superiority effect (WSE) has been consistently observed. We present 3 experiments in which the WSE is replicated and generalized to hitherto untested knowledge domains and participant pools. To estimate the content validity of the verbal recall modes, free recall performance is analyzed as a function of modality, taking into account cued recall performance, which is known to allow more complete knowledge recollection. Throughout all experiments, free recall performance was better in the written than in the oral diagnosis of list-like knowledge. The results recommend written diagnosis at least for similarly structured knowledge domains. Future research should investigate to which degree writing superiority also holds for other kinds of knowledge domains and which language production and retrieval processes are responsible for the effect.

Published: August 2018

A partir do surgimento e disponibilização de base de Modelos Digitais de Elevação (MDE) de abrangência mundial e gratuitos, houve um expressivo aumento de trabalhos para a realização da modelagem de superfície da Terra. Contudo, a qualidade dos produtos gerados a partir desses dados e as escalas adequadas de uso ainda carecem de estudos mais detalhados. O presente trabalho visou analisar a precisão altimétrica de dados AW3D, SRTM e do projeto SPMGGO50 do IBGE na bacia hidrográfica do Ribeirão São Domingos (BHSD), município de Catalão/GO, avaliando a adequação desses dados às escalas 1:50.000, 1:100.000 e 1:250.000, observando a metodologia indicada pelo Padrão de Exatidão Cartográfica dos Produtos Cartográficos Digitais (PEC-PCD). Foram coletados 44 pontos de controle/validação em campo para a aferição dos modelos. Para tanto, foram calculados a tolerância vertical e o Erro médio quadrático dos modelos em relação aos pontos de validação. Os sensores SRTM e AW3D e o projeto SPMGGO50 atingiram a classe “B” na escala 1:100.000 e “A” na escala 1:250.000.

Published: August 2018

Este trabalho tem como objetivo utilizar indicadores para avaliar o processo de expansão da pastagem no Pantanal de Cáceres-Mato Grosso, no período de 1999 a 2014. Realizou-se uma análise espaço-temporal dos últimos 15 anos, com intervalo de tempo de cinco anos, por meio de imagens do Landsat 5 e Landsat 8. Três classes de uso da terra foram mapeadas: Vegetação Natural Florestal, Pastagem e Savana Arborizada + Savana Gramíneo-Lenhosa. As classes geradas possibilitaram o cálculo dos índices para a determinação de um cenário ambiental na área de estudo. Os indicadores mostraram um aumento crescente da área pastagem, na ordem de 182,34% para o Índice de Ocupação de Pastagem e 23,08% para Índice de Expansão de Pastagem até o ano de 2014 e demonstraram que a supressão da Vegetação Natural Florestal é maior que a supressão da Savana Arborizada + Savana Gramíneo Lenhosa. A oscilação dos índices no período de estudo pode ser atribuída à ocorrência de queimadas, secas, cheias e vazão. Os indicadores apontaram que, apesar da expansão da pastagem, o Pantanal de Cáceres é uma região que apresenta uma dinâmica ambiental complexa, rica e diversificada, o que sugere a necessidade de monitoramento constante para verificação de ações antrópicas que ameaçam seu equilíbrio ambiental.
A Preliminary Evaluation of Symbiotic N Fixation in Mungbean
Authors: Salley Charles , Bhardwaj Harbans L.
Published: August 2018

We are interested in developing mungbean [(Vigna radiata (L.) R. Wilczek] as a short duration summer crop to be produced in rotation with winter wheat due to its’ increasing popularity and potential for Symbiotic N Fixation (SNF). However, scarcity of mungbean SNF information is limiting to support its use as an N-fixing crop. We conducted a greenhouse study with ten mungbean genotypes and twelve Bradyrhizobium strains. The objective was to study nodule traits (number and size) and chlorophyll concentration in leaves using Minolta SPAD meter using a CRD design with six replications. Eight to ten seeds of each of the 120 combinations were planted in vermiculite and inoculated with the bacterial strains. Upon germination, plants were thinned to six plants per pot. The data were recorded on approximately 40-day old plants. Results indicated that variation for nodule traits was not significant. However, significant effects of bradyrhizobial strains and mungbean genotypes on SPAD readings were observed. Results indicated existence of specificity between mungbean genotypes and bradyrhizobial strains, as indicated by significant interaction for SPAD values. We identified three bradyrhizobial strains (Strain-11 isolated from partridge pea, Strain-12 isolated from Baptisia sp., and Strain-3-CB 756, wide range type strain from Australia) to be highly efficient. Three mungbean genotypes (MB-80, TexSprout, and MB-84) were identified to be best for SNF. The results provide basic information to support future detailed SNF research in mungbean.

Two experiments were carried out in the experimental field of the Universidade Estadual Paulista-UNESP in Ilha Solteira, São Paulo state, Brazil, in a greenhouse from April to July 2015. This study aimed at evaluating the best sowing season and response to nitrogen doses for the cultivars of yellow oat São Carlos and black IAPAR 61. The experiments were conducted in randomized blocks designs in a factorial scheme with three replicates. The sowing seasons were April 23, May 08, and May 5 and the nitrogen doses were 0; 12.5; 25; 35.5 and 50 kg ha-1 cycle. Harvests at 30 and 60 days were conducted in order to estimate of the production of dry weight (DW), crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF). For a productivity of DW, there was interaction between sowing season and oat cultivars and significant differences for CP in the second harvesting. For NDF, a significant difference was observed between harvesting. The most suitable time for sowing of both yellow oats and black oats is early May. Dry weight yield and the CP content of yellow oats increased linearly with increasing nitrogen rates while for black oats a maximum DM yield were obtained with the application of 43.5 kg ha-1 of N.

The production of yellow passion fruit seedlings is common among producers. Low cost techniques to maximize and reduce the cost of production with the application of cattle manure make the production of seedlings feasible. The objective of experiment was to evaluate different concentrations of cattle manure in substrate with and without liquid the biofertilizer in the production of yellow passion fruit seedlings. The experiment was carried out at the Universidade Estadual da Paraíba, Catolé do Rocha county, Paraíba state. The experimental design was completely randomized, in a 5 × 2 factorial scheme, with 5 repetitions end 3 plants per plot. The treatments consisted of five concentrations of cattle manure (0, 20, 40, 60, and 80% of the substrate volume), without and with the biofertilizer (10 mL plant-1). Sixty days after sowing, the following items were evaluated: plant height; number of leaves; root length; leaf area; leaf fresh mass; stem fresh mass; root fresh mass; aerial part fresh mass; total plant fresh mass; aerial part dry mass, and the Dickson quality index. The concentrations between 38 and 69% of composted cattle manure combined with the application of liquid biofertilizer increased the initial growth of yellow passion fruit plants, making its use feasible in the production of seedlings.

The aim of this study was to perform a comparative analysis of the methods of ergonomics assessment RULA, REBA, OWAS and TOR-TOM, which the intent is to highlight similarities and differences in their use, during tillage operation with farm machinery. The study was conducted through an exploratory research in Boa Vista do Incra, RS, in August 2017, during soil preparation operation, with a tractor-subsoiler set. The operation was filmed over a period of 10 hours. After that, it was selected one hour of video, which was assumed to be representative, the video was analyzed by the methods RULA, REBA, OWAS and TOR-TOM through the software Ergolândia 5.0 and TOR-TOM, with the aid of information on noise, temperature and strength. For the comparative analyses, it was analyzed the ease of application, the importance of posture and complementary variables, and the scope of activity and postural factors. The OWAS method showed highlight in the ease of application, while the REBA and RULA methods stood out for the importance of the postural variables. For the importance of the complementary variables, RULA, followed by REBA, are worth mentioning as the most suitable. Similar results were obtained for the scope of posture factors, especially for these two methods. Regarding the scope of activity factors, the TOR-TOM obtained the most satisfactory results. Thus, the comparative analysis has highlighted the RULA method as the most suitable for postural analysis in agricultural machinery, besides the REBA method, for presenting very similar situations, contemplating full body analysis.

Nitrogen is a component of proteins contained in grains and potassium an enzymatic activator in nitrate (NO3-) assimilation and contributes to the translocation and storage of plant assimilates. Together they can increase protein contents of wheat grains. This research aimed to evaluate whether the interaction between nitrogen (N) and potassium (K) fertilizations in irrigated wheat in the Cerrado region of the Mato Grosso State increases the content and accumulation of N, K, and protein in wheat grains. The experiment was carried out in the field for two consecutive years (2014 and 2015) in the Federal University of Mato Grosso. It was designed in randomized blocks in 52 fractional factorial, composed of combinations between five doses of each of N and K, 13 treatments combinations in total with four replicates. After harvest, the grains were dried to determine the contents of N, K, and protein. The nitrogen content was influenced by nitrogen doses in both years and the accumulation significantly influenced by the nitrogen and potassium doses with an average increase among the years of 55.29% as a function of the potassium application. Nitrogen influenced the accumulation of potassium only in 2015 with effect for potassium in both years. Although there was no interaction between treatments, the influence of K on N absorption was evident. Contents and accumulations of N and K and the content of protein in wheat grains are influenced by N and K fertilizations.

Published: August 2018

The saccharine sorghum has been investigated as a complementary source of raw material for ethanol production, especially during the sugarcane off-season, however, it has been susceptible to the attack of the sugarcane borer Diatraea saccharalis. The objective of this work was to verify the effect of sorghum cultivars on D. saccharalis’ biological parameters. Cultivars, BRS 506, BRS 509 and BRS 511 were used to determine duration and survival rates of eggs, larvae, pre-pupae and pupa phases, along with larval weight and adult longevity. D. saccharalis completed its biological cycle in all treatments, however, when fed with dry extracts of BRS 509 cultivar, the net reproduction rate, the intrinsic rate of increase and the finite rate of increase was superior from the others. BRS 506 was the cultivar that negatively affected D. saccharalis’ biological parameters, with possible antibiosis effect. Based on this study, the sorghum cultivars evaluated are not recommended for a grain production system, since D. saccharalis’ larvae presented good development when fed with its dry extract incorporated into the diet.

Stimulating the use of renewable energy instead of fossil fuels, especially biofuels, has become one of the alternatives to the issue of global warming. Of these species listed for the production of biodiesel is the Jatropha curcas crop. The aim of this study was to analyze the drying of the seeds of Jatropha, as well as to verify the effect of the different temperatures on the quality of the product, germination percentage and Emergence speed index (ESI). The experimental design was a completely randomized design, with four replications. Experimental drier was used to test the temperatures of 29, 35, 40, 45 and 50 °C and the data were compared by regression equation. The vigor and germination of the jatropha seeds were little affected as the drying temperatures were increased to 50 °C.

Various types of industrial wastes have been tested as a source of pasture fertilization. However, little is known about the sludge of the gelatine industry. This study aimed at testing gelatine sludge as a soil amendment by assessing the chemical modifications caused in the soil profile. The experiment was conducted in Araguaina, Tocantins, using a typical Quartzipsamment soil (Entisols) from February to November 2013. Four doses were tested in experimental plots: 0, 50, 150 and 300 m3 ha-1. Soil sampling was performed at four depths: 0-5, 5-10, 10-20 and 20-30 cm with collection at the beginning and the end of the experimental period. Five grazing simulations of 21 days of rest of Piatã grass were testes. The gelatine sludge was able to raise the contents of calcium, phosphorus, and sum of bases only in the superficial layer (0-5 cm) and did not alter the pH, potential acidity and saturation by base, indicating that there was no use restriction due to salinization or acidification. Therefore, it was concluded that the maximum tested dose (300 m3 ha-1) improved the chemical characteristics of the soil, especially in the 0-5-cm layer.
Psychische Belastung, Burnout, Perfektionismus, Optimismus, Pessimismus und Erholungskompetenz bei professionellen Sängerinnen und Sängern
Authors: Hodapp Bastian
Published: August 2018

Bislang existieren kaum (musik-)psychologische Studien, welche die gesundheitliche Situation von Berufssänger/innen adressieren. Mit N = 313 Teilnehmenden handelt es sich bei der hier vorgestellten Forschungsarbeit um eine der bislang größten Studien, in welcher gesundheitspsychologische Aspekte bei Profisänger/innen untersucht wurden. Es konnte gezeigt werden, dass die Sänger/innen trotz hoher beruflicher Belastungen in 16 von 27 Burnout-Kennwerten niedrigere Werte aufweisen als die Personen der repräsentativen Vergleichsstichprobe. Bei den elf anderen Burnout-Kennwerten zeigte sich kein statistisch signifikanter Unterschied zwischen den beiden Gruppen. Mit den in den Regressionsanalysen berücksichtigten Prädiktoren lassen sich bis zu 40 Prozent des Kriteriums Burnout erklären. Als aussagekräftigste Prädiktoren konnten die Variablen Erholungskompetenz, Optimismus und Pessimismus identifiziert werden. Perfektionismus als unter Musiker/innen häufig stark ausgeprägte Persönlichkeitseigenschaft trug wider Erwarten kaum zur Vorhersage der Burnout-Ausprägungen der Berufssänger/innen bei. Für präventive und rehabilitative Maßnahmen mit Profisänger/innen lässt sich aus den Befunden mit Blick auf eine (potenzielle) Burnout-Erkrankung die Empfehlung ableiten, sich eher auf die Ressourcen der Musiker/innen (Erholungskompetenz, Optimismus) zu konzentrieren und weniger auf deren scheinbare Defizite (Perfektionismus).

Published: August 2018

Este artigo pretende compreender as relações entre popularização do passado e democratização da história. Para tal, realizamos três estudos de caso que nos permitem pensar em outros regimes de escrita, presença e memória. No primeiro caso, descrevemos um suposto plágio que a revista de divulgação Leituras da História teria cometido a partir da Wikipédia, no segundo analisamos como as artes cênicas representam uma possibilidade ativa de relação com o passado traumático e, no terceiro, lidamos com a forma pela qual inscrições históricas no espaço urbano são constantemente ressignificadas. Concluímos que a popularização do passado em diferentes meios desestabiliza os lugares tradicionais de produção e consumo de conhecimento histórico, e lançam uma série de questões para repensar o lugar da historiografia na contemporaneidade. Palavras-chave: Popularização do passado.

A formação do movimento feminista brasileiro: considerações a partir de narrativas de mulheres que militaram contra a ditadura civil-militar
Authors: Kreuz Débora Strieder
Published: August 2018

A partir dos anos 1960, grande parte do mundo ocidental viu emergir novas formas de manifestação relacionadas com pautas até então consideradas secundárias.  No Brasil, contudo, vivíamos um momento conturbado politicamente, com a implantação, em 1964, de uma ditadura civil-militar que perdurou até 1985 e reprimiu violentamente toda e qualquer forma de resistência. Em meados da década de 1970, entretanto, iniciou-se a rearticulação de novos movimentos sociais, os quais, além da luta pelo retorno da democracia, inseriram novas discussões no cenário. O artigo se propõem a analisar, a partir de narrativas de militantes que atuaram em organizações clandestinas de combate a ditadura e posteriormente no movimento feminista, a maneira como este se organizou no país. Intentamos compreender a relação entre a participação em grupos revolucionários e a posterior militância feminista das narradoras. Para a análise dos relatos partimos de duas categorias analíticas principais: memória e gênero. A partir do que elenca a metodologia da História Oral temos acesso a memória das militantes, que é compreendida enquanto um processo de constante rearranjo em virtude das experiências vividas. Assim, o trabalho busca a compreensão da forma como o movimento feminista brasileiro de segunda onda se organizou, sobretudo a partir das vivências daquelas que lutaram contra o arbítrio ditatorial, partindo do pressuposto que tal experiência foi fundamental para a caracterização das suas especificidades. Palavras-chave: Mulheres.

Génétique textuelle et écritures mono- et plurilingues
Authors: Leblay Christophe
Published: August 2018

Le choix méthodologique de ce travail pose la génétique textuelle comme discipline de référence ; celle-ci prend en compte prioritairement une description des phénomènes intrinsèques de scripturalité, bien avant de s’intéresser au seul produit final. Les concepts clés de la génétique textuelle (successivité, immédiateté, linéarité) sont réactualisés et transférables à de nouveaux corpus hétérogènes, collaboratifs, polygraphiques et professionnels. En ajoutant l’appareil conceptuel génétique, il devient possible de suivre et de visualiser le pas-à-pas des transformations : le retour critique sur sa propre écriture s’apprend, se raffine à l’aide de ressources visuelles. À partir de repères élémentaires en génétique textuelle, il s’agit de considérer les différentes manières d’étudier ce que la génétique nomme avant-texte, afin de pouvoir classer les principaux corpus génétiques, depuis les premiers corpus littéraires jusqu’aux plus récents, multimodaux, dont font partie les écritures professionnelles monolingue (rédaction) et plurilingue (traduction).
Diversité des pratiques dans la production plurilingue de textes politiques. Comparaison entre trois partis suisses
Authors: Bohn Véronique
Published: August 2018

Qu’ils soient étatiques ou non, les acteurs qui évoluent dans un système officiellement plurilingue doivent tenir compte de l’existence de plusieurs communautés linguistiques. La question qui se pose alors est de savoir comment il est possible de communiquer politiquement dans un tel contexte. En particulier, il paraît essentiel pour l’existence d’une vie démocratique d’empêcher que les discussions ne soient cloisonnées par publics de langues maternelles différentes et donc d’assurer une coordination des messages entre les langues. Dans notre étude qualitative, nous nous intéressons aux dispositifs que trois partis politiques suisses ont mis en place pour assurer ce lien dans la production des périodiques destinés à leurs membres. Ces pratiques, que nous appelons « modes de coordination interlinguistique », peuvent impliquer, à des degrés divers, l’utilisation de la traduction. Au-delà de la description de ces modes, il s’agit de comprendre les logiques qui guident le choix d’une pratique particulière et qui sont définies comme l’ensemble cohérent d’éléments représentationnels et matériels, internes et externes au parti. Pour comprendre ces logiques, des entretiens semi-structurés ont été menés avec les responsables des publications, et les logiques qu’ils permettent de mettre en évidence ont ensuite été comparées. En particulier, l’accent est mis sur les éléments qui divergent d’un parti à l’autre et qui semblent expliquer l’adoption d’une pratique plutôt qu’une autre. Les résultats sont exposés selon trois grands thèmes : développement historique des publications, perception de la traduction et articulation entre stratégie politique et système de valeurs. De manière plus générale, l’étude suggère que de nombreux éléments entrent en ligne de compte dans la production plurilingue des textes politiques et que la situation est bien plus complexe qu’une simple distinction entre traduction et non-traduction.
Éthos des traducteurs et langues cibles : les traductions d’oeuvres spirituelles espagnoles aux Pays-Bas méridionaux au XVIe et XVIIe siècle
Authors: Behiels Lieve
Published: August 2018

Au XVIe et XVIIe siècle, les Pays-Bas méridionaux, grâce à leur intégration dans la monarchie hispanique, représentent un carrefour d’échanges dans tous les domaines de la culture, particulièrement en ce qui concerne la spiritualité catholique. Ils sont en outre un centre important en matière d'imprimerie et de traduction. Ainsi, de nombreux auteurs religieux espagnols ont été traduits non seulement dans les langues vernaculaires (le néerlandais, le français, parfois l’anglais), mais aussi en latin. À partir de quatre traductions de l’oeuvre d’un auteur franciscain espagnol, Alonso de Madrid, en latin, en français et en néerlandais, nous nous penchons sur l’image de soi que projettent les auteurs des péritextes et sur le rapport entre cet éthos et la langue, donc le public cible. L’analyse des épîtres dédicatoires des traducteurs montre qu’à la position dans la hiérarchie intellectuelle et politique des traducteurs et de leurs publics cibles correspond une hiérarchie des langues et que le choix d’une langue vernaculaire comme le néerlandais peut causer la réorientation du skopos de la traduction.
A Model for Defining the Concept and Practice of Translation, from the Perspective of Greimassian Semiotics
Authors: Troqe Rovena
Published: August 2018

In this study, a new model of translation as a general theoretic concept and as a social practice is outlined, drawing form Greimassian semiotics. As a theoretic concept, translation is defined by the Semiotic Square of Translation as the emergence of the general category self coming into being in relation to the category non-self, through the semio-logic operations that correlate the immanent concepts, equivalence and difference. As a social practice, translation arises from the contractual interaction between two actants, the Initiator and the Translator, which operate through acts of manipulation, performance and sanction. This theoretical framework is applied to the study of a parallel corpus.
Extinction recall of fear memories formed before stress is not affected despite higher theta activity in the amygdala

Published: August 2018

Stress is known to exert its detrimental effects not only by enhancing fear, but also by impairing its extinction. However, in earlier studies stress exposure preceded both processes. Thus, compared to unstressed animals, stressed animals had to extinguish fear memories that were strengthened by prior exposure to stress. Here, we dissociate the two processes to examine if stress specifically impairs the acquisition and recall of fear extinction. Strikingly, when fear memories were formed before stress exposure, thereby allowing animals to initiate extinction from comparable levels of fear, recall of fear extinction was unaffected. Despite this, we observed a persistent increase in theta activity in the BLA. Theta activity in the mPFC, by contrast, was normal. Stress also disrupted mPFC-BLA theta-frequency synchrony and directional coupling. Thus, in the absence of the fear-enhancing effects of stress, the expression of fear during and after extinction reflects normal regulation of theta activity in the mPFC, not theta hyperactivity in the amygdala.

Oral squamous cell carcinoma (OSCC) is a major malignant cancer of the head and neck. Long non-coding RNAs (lncRNAs) have emerged as critical regulators during the development and progression of cancers. This study aimed to identify a lncRNA-related signature with prognostic value for evaluating survival outcomes and to explore the underlying molecular mechanisms of OSCC. Associations between overall survival (OS), disease-free survival (DFS) and candidate lncRNAs were evaluated by Kaplan–Meier survival analysis and univariate and multivariate Cox proportional hazards regression analyses. The robustness of the prognostic significance was shown via the Gene Expression Omnibus (GEO) database. A total of 2,493 lncRNAs were differentially expressed between OSCC and control samples (fold change >2, p < 0.05). We used Kaplan–Meier survival analysis to identify 21 lncRNAs for which the expression levels were associated with OS and DFS of OSCC patients (p < 0.05) and found that down-expression of lncRNA AC012456.4 especially contributed to poor DFS (p = 0.00828) and OS (p = 0.00987). Furthermore, decreased expression of AC012456.4 was identified as an independent prognostic risk factor through multivariate Cox proportional hazards regression analyses (DFS: p = 0.004, hazard ratio (HR) = 0.600, 95% confidence interval(CI) [0.423–0.851]; OS: p = 0.002, HR = 0.672, 95% CI [0.523–0.863). Gene Set Enrichment Analysis (GSEA) indicated that lncRNA AC012456.4 were significantly enriched in critical biological functions and pathways and was correlated with tumorigenesis, such as regulation of cell activation, and the JAK-STAT and MAPK signal pathway. Overall, these findings were the first to evidence that AC012456.4 may be an important novel molecular target with great clinical value as a diagnostic, therapeutic and prognostic biomarker for OSCC patients.

Development of electrocatalysts for hydrogen evolution reaction (HER) with low overpotential and robust stability remains as one of the most serious challenges for energy conversion. Herein, a serviceable and highly active HER electrocatalyst with multilevel porous structure (Co‐Co2P nanoparticles@N, P doped carbon/reduced graphene oxides (Co‐Co2P@NPC/rGO)) is synthesized by Saccharomycete cells as template to adsorb metal ions and graphene nanosheets as separating agent to prevent aggregation, which is composed of Co‐Co2P nanoparticles with size of ≈104.7 nm embedded into carbonized Saccharomycete cells. The Saccharomycete cells provide not only carbon source to produce carbon shells, but also phosphorus source to prepare metal phosphides. In order to realize the practicability and permanent stability, the binderless and 3D electrodes composed of obtained Co‐Co2P@NPC/rGO powder are constructed, which possess a low overpotential of 61.5 mV (achieve 10 mA cm−2) and the high current density with extraordinary catalytic stability (1000 mA cm−2 for 20 h) in 0.5 m H2SO4. The preparation process is appropriate for synthesizing various metal or metal phosphide@carbon electrocatalysts. This work may provide a biological template method for rational design and fabrication of various metals or metal compounds@carbon 3D electrodes with promising applications in energy conversion and storage.

In this paper, the utilization of plasmon‐induced cleavage of CI bond in the structure of iodonium salt followed by grafting of organic radicals to Au surface is proposed. The plasmon is excited by the coupling of Au‐covered optical fiber with the laser light source, with wavelength corresponding to the plasmon absorption band, and immersion of fiber in the solution of iodonium salt. Grafting procedure is monitored through the shift of surface plasmon resonanse (SPR) position during the laser light transmission. Further verifications are performed using the surface enhanced Raman spectroscopy (SERS) and scanning electron microscopy and energy‐dispersive X‐ray spectroscopy methods. Only in the case of coincidence of coupled laser emission and initial SPR absorption band wavelengths efficient activation of diaryliodonium salt (IS) is observed. With the aim to introduce hydrophobic and repellent surface properties the di‐[3,5‐bis(trifluoromethyl)phenyl]iodonium tetrafluoroborate salt is used. Surface functionality is further tested using the wettability and antifouling test. Proposed method for the first time utilizes the plasmonic phenomenon as an effective tool for initiating the iodonium salt heterophase reaction and can be considered as extremely effective approach in the case of surface activation, in terms of energy and materials harvesting.

Published: August 2018

Although diversified biological structures have evolved fog collection abilities, the typical speeds of the condensed water droplets on these surfaces are too slow to have practical utility. The main challenge focuses on the elimination of the interfacial hydrodynamic resistance without external energy support. Here, an unusual strategy for superfast self‐support transfer condensed droplets is supported by sliding on seta of desert scorpion. It can be rapidly wetted by the fog droplets owing to its conical shape with linear gradient channels. A loss of interfacial resistance by this hydrodynamically lubricating water membrane could significantly accelerate the movement of the droplets, thus making its velocity increasing by one order of magnitude, or even more. Inspired by this novel strategy, the novel bioinspired materials are fabricated with the similar gradient channel structures and droplet transportation mode, which can make the condensed droplets spontaneously slide on the low‐friction liquid membrane. The fundamental understanding of superfast fog capture and the sliding dynamics of condensed droplets in this system could inspire to develop novel materials or various systems to transfer liquid fast and efficiently without external energy support.

Published: August 2018

2D monolayer cell cultures are routinely utilized for preclinical cancer drug screening, but the results often do not translate well when drugs are tested in vivo. To address this limitation, a biocompatible chitosan‐PEG‐genipin hydrogel (CSPG gel) is synthesized to create a gel that can be easily dispensed into 96‐well plates at room temperature and neutral pH. The stiffness of this gel is tailored to be within the range of human glioblastoma tissue to promote the formation of tumor spheroids. Differences in cell morphology, proliferation rate, and dose‐dependent drug cytotoxicity are compared among cell spheroids grown on CSPG gels, cells in monolayer culture on tissue culture polystyrene, and cells cultured on Matrigel. Tumor spheroids on CSPG gels display statistically significantly greater resistance to chemotherapeutics than in the conditions where cells do not form spheroids. Gene expression analysis suggests that resistance of cells on CSPG gels to the therapy may be partially attributed to upregulation of ATP‐binding cassette transporters and downregulation of DNA mismatch repair genes stimulated by spheroid formation. These findings suggest CSPG gel generates tumor spheroids that better reflect the malignant behavior of glioblastomas and provides a cost‐effective substrate for preclinical, high‐throughput screening of potential cancer therapeutics.

Published: August 2018

Perovskite‐type solid‐state electrolytes exhibit great potential for the development of all‐solid‐state lithium batteries due to their high Li‐ion conductivity (approaching 10−3 S cm−1), wide potential window, and excellent thermal/chemical stability. However, the large solid–solid interfacial resistance between perovskite electrolytes and electrode materials is still a great challenge that hinders the development of high‐performance all‐solid‐state lithium batteries. In this work, a perovskite‐type Li0.34La0.51TiO3 (LLTO) membrane with vertically aligned microchannels is constructed by a phase‐inversion method. The 3D vertically aligned microchannel framework membrane enables more effective Li‐ion transport between the cathode and solid‐state electrolyte than a planar LLTO membrane. A significant decrease in the perovskite/cathode interfacial resistance, from 853 to 133 Ω cm2, is observed. It is also demonstrated that full cells utilizing LLTO with vertically aligned microchannels as the electrolyte exhibit a high specific capacity and improved rate performance.
The role of compensation in explaining harmful effects of overtime work on self‐reported heart disease: Preliminary evidence from a Germany prospective cohort study
Authors: Li Jian , Siegrist Johannes
Published: August 2018

Background

Research evidence suggests harmful effects of overtime work on risk of heart disease. However, whether withdrawing compensation for overtime work (time‐off or money) provides a relevant explanation of this association has not been explored.

Methods

Using cohort data, we included 6345 employees from Germany (3079 men and 3266 women), and applied Poisson regression analysis to examine the prospective association of overtime work without compensation with risk of self‐reported incident heart disease over 2 years.

Results

Uncompensated overtime work was associated with an elevated risk of heart disease after adjustment for relevant variables (RR = 1.85, 95%CI: 1.05‐3.25), compared to no overtime work. Stratified analyses indicated particularly strong effects among women and among employees with low socioeconomic position.

Conclusions

In line with the stress‐theoretical model of effort‐reward imbalance at work, these findings document an important role of compensation on heart disease in the frame of overtime work.
