A Brief Exposure to Leftward Prismatic Adaptation Enhances the Representation of the Ipsilateral, Right Visual Field in the Right Inferior Parietal Lobule
Authors: Crottaz-Herbette Sonia , Fornari Eleonora , Tissieres Isabel , Clarke Stephanie 
Published: September 2017

AbstractA brief exposure to rightward prismatic adaptation (PA) was shown to shift visual field representation within the inferior parietal lobule (IPL) from the right to the left hemisphere. This change in hemispheric dominance could be interpreted as (1) a general effect of discrepancy in visuomotor alignment caused by PA or (2) a direction-specific effect of rightward PA. To test these hypotheses, we compared the effects of rightward and leftward PA on visual representation in normal human subjects. Three groups of normal subjects underwent an fMRI evaluation using a simple visual detection task before and after brief PA exposure using leftward- or rightward-deviating prisms or no prisms (L-PA, R-PA, neutral groups). A two-way ANOVA group × session revealed a significant interaction suggesting that PA-induced modulation is direction specific.Post hocanalysis showed that L-PA enhanced the representation of the right visual field within the right IPL. Thus, a brief exposure to L-PA enhanced right hemispheric dominance within the ventral attentional system, which is the opposite effect of the previously described shift in hemispheric dominance following R-PA. The direction-specific effects suggest that the underlying neural mechanisms involve the fine-tuning of specific visuomotor networks. The enhancement of right hemispheric dominance following L-PA offers a parsimonious explanation for neglect-like symptoms described previously in normal subjects.
Localization of Cdc7 Protein Kinase During DNA Replication in Saccharomyces cerevisiae

Published: September 2017

Abstract
DDK, a conserved serine-threonine protein kinase composed of a regulatory subunit, Dbf4, and a catalytic subunit, Cdc7, is essential for DNA replication initiation during S phase of the cell cycle through MCM2-7 helicase phosphorylation. The biological significance of DDK is well characterized, but the full mechanism of how DDK associates with substrates remains unclear. Cdc7 is bound to chromatin in the Saccharomyces cerevisiae genome throughout the cell cycle, but there is little empirical evidence as to specific Cdc7 binding locations. Using biochemical and genetic techniques, this study investigated the specific localization of Cdc7 on chromatin. The Calling Cards method, using Ty5 retrotransposons as a marker for DNA–protein binding, suggests Cdc7 kinase is preferentially bound to genomic DNA known to replicate early in S phase, including centromeres and origins of replication. We also discovered Cdc7 binding throughout the genome, which may be necessary to initiate other cellular processes, including meiotic recombination and translesion synthesis. A kinase dead Cdc7 point mutation increases the Ty5 retrotransposon integration efficiency and a 55-amino acid C-terminal truncation of Cdc7, unable to bind Dbf4, reduces Cdc7 binding suggesting a requirement for Dbf4 to stabilize Cdc7 on chromatin during S phase. Chromatin immunoprecipitation demonstrates that Cdc7 binding near specific origins changes during S phase. Our results suggest a model where Cdc7 is loosely bound to chromatin during G1. At the G1/S transition, Cdc7 binding to chromatin is increased and stabilized, preferentially at sites that may become origins, in order to carry out a variety of cellular processes.

Published: September 2017

Este trabalho tem como objetivo estudar a melhor região de microemulsão através do cálculo integral da área, mediante a variação de alguns parâmetros. Utilizou-se o óleo de coco saponificado (OCS) tensoativo, butanol (cotensoativo), querosene (componente apolar), água ou salmoura (KCl) (componente polar). As curvas de solubilidade (binodal) foram determinadas utilizando p método de turbidez. A composição da mistura para cada ponto da binodal foi determinada a partir de quantidades tituladas até a turbidez usando balança analítica. Estudou-se a influência da razão cotensoativo/tensoativo (C/T) e a salinidade por meio da variação desses parâmetros. Priorizando a região microemulsionada, verificou-se que para o sistema com água, o aumento da razão C/T amplia a região de microemulsão. O sistema que apresentou melhor área nesse caso foi o água-querosene-butanol/OCS=3. Para um sistema com salmoura, verificou-se que o aumento da salinidade diminuía a região de microemulsão, para uma dada razão C/T fixa. Os sistemas que apresentaram melhor área, nesse caso, foram os sistemas querosene-butanol/OCS=2/2%KCl e querosene-butanol/OCS=3/2%KCl. Analisando a influencia da razão C/T e salinidade juntas, verificou-se que o aumento da razão C/T associado ao aumento da salinidade diminui a região de microemulsão(querosene/butanol/OCS=2-água-2%KCl).

Authors: Studzieniecki Tomasz , Soares Jakson Renner Rodrigues 
Published: September 2017

The purpose of this article is the answer of the question if interregional cooperation supported by economic policy of UE fosters tourism development and if yes in what way. The relation between tourism and interregional cooperation is relatively seldom analysed in comparison with other strands of territorial cooperation such as crossborder and transnational cooperation. This results from specific philosophy of interregional cooperation.In order to achieve the purpose of the paper it was necessary to present the system of interregional cooperation management and model of tourism in European Union. The paper analyses the period 2007 – 2013 when INTERREG IVC provided funding for interregional cooperation across Europe.The overall objective of the INTERREG IVC Programme was to improve the effectiveness of regional policies and instruments with special attention to the areas of support such as:• innovation and the knowledge economy,• environment and risk prevention. Tt could be assumed that it had been possible to include tourism in tourism projects implemented within Interreg IV C. To prove it the qualitative and quantitative analysis of 204 projects divided into 12 themes has been done. Aditionally the database of good practices was analyzed. The analysis of its documents allowed to identify 60 tourism-related good practices. These practices focused on cultural and sustainable tourism.
El punto de partida del análisis bioético de la ciencia y la tecnología: críticas al determinismo

Published: September 2017

¿Cuál debería ser el punto de partida del análisis bioético de la ciencia y la tecnología? En casi medio siglo de historia se han formulado diversas perspectivas de análisis bioético de la ciencia y la tecnología. En este artículo se reconoce el amplio contexto teórico sobre el tema y no se va indagar sobre él, sino sobre un asunto más básico: la necesidad de precisar un punto de partida común a los distintos análisis, para evitar algunos presupuestos frecuentemente viciados. En el artículo se propone como punto de partida para el análisis bioético señalado, una perspectiva internalista, orientada fundamentalmente a enfrentar la tarea de desmantelar presupuestos deterministas, y no una mirada externalista, tradicional y moralizante. En el texto se precisan los distintos sentidos de los puntos de vista deterministas sobre la ciencia y la tecnología comúnmente asumidos, y sus relaciones con los juicios morales. También se analiza, de forma comparada, la manera como varios autores y perspectivas toman o cuestionan este tipo de planteamientos. El aporte fundamental del artículo consiste en proponer como perspectiva ética básica, la tarea de abrir la caja negra de los juicios morales, y disolver las precarias comprensiones deterministas de la naturaleza de la ciencia y de la tecnología, en la que se quedan presos muchos de los análisis bioéticos sobre el tema.

No Brasil, a oferta de projetos padronizados e com dimensões mínimas para as habitações de interesse social demanda maior atenção e aponta a necessidade do desenvolvimento de projetos mais eficientes considerando as transformações que ocorrem nos costumes e nos perfis familiares. A participação dos usuários no processo do projeto pode contribuir na qualidade do ambiente construído ao permitir o entendimento das necessidades desses usuários, pois este processo é baseado no aprimoramento da comunicação entre leigos e profissionais. Nesse contexto, o objetivo deste trabalho foi realizar uma simulação com o uso do modelo tridimensional físico ajustável como modo de investigar as prioridades e desejos dos usuários das habitações de interesse social. O modelo permite ajustes e alterações rápidas nas posições de paredes e aberturas, proporcionando uma leitura clara de diferentes opções de projeto. Além da simulação, o método de pesquisa também incluiu um questionário e a técnica de preferência declarada com modelos digitais. Foi possível observar que essas ferramentas auxiliaram na coleta das informações, permitindo que os entrevistados expressassem suas prioridades e as motivações das suas escolhas. A simulação com modelo físico ajustável demonstrou eficácia na comunicação do projeto, para pessoas leigas ao aproximar os envolvidos das decisões sobre o projeto da moradia e auxiliar os futuros moradores a fazerem escolhas mais conscientes.
Memória, identidade e resistência: o desenvolvimento econômico como ameaça

Published: September 2017

Busca-se neste artigo, por meio de um estudo de caso, discutir o papel da identidade fundamentada na memória como luta de resistência à desapropriação de terras. O marco teórico deste trabalho está fundado nas contribuições de Erving Goffman (1978), Stuart Hall (2003), Zygmunt Bauman (2006) e Anthony Giddens (2002), em torno do conceito de identidade e de Peter Burke (2000) em relação à memória. Apontamos que, frente a pós-modernidade caracterizada pela liquidez, a identidade coletiva resgatada por meio da memória pode ser uma arma de resistência e afirmação identitária, principalmente tratando-se de grupos étnicos que possuem respaldo constitucional específico, como os índios.

Mosquito density could predict the risk of Dengue Virus (DENV) transmission in certain area. Ovitrap Index (OI) is one of the methods to measure the mosquito density beside other methods such as Stegomyia Indices and free larvae index. Ovitrap index is cheaper, more appliacable and sensitive to detect Aedes sp activity to lay their eggs on the wall of container. The aims of this research were to measure ovitrap index in endemic DENV areas, to find out the preferences of female Aedes sp to lay their eggs, and find out the correlation between OI and dengue cases in endemic DENV areas. Type of this study was decriptive with cross sectional design. The area of study was in Community Health center Purwokerto Timur II in Kranji, Sokanegara and Purwokerto Lor. Ovitrap were installed at 50 houses of each vilagges (one indoor, one outdoor), with total ovitrap 100 in each villages. After 6 days of installation, ovistrips were collected and the eggs were counted. The Ovitrap index in three villages were observed at percentage more than 50%, with the highest OI detected in Kranji Village (97.56%). Female Aedes sp were monitored to lay their eggs outdoor than indoor. The OI is not always relevant to predict the dengue cases but could inform the risk of DENV tranmission in certain area. The community should do efforts to minimize potential breeding sites, mainly unused container outdoor to reduce the mosquito density.
Sorption of Iron–Cyanide Complexes on Goethite in the Presence of Sulfate and Desorption with Phosphate and Chloride
Authors: Rennert Thilo , Mansfeldt Tim 
Published: September 2017

ABSTRACTSoils are contaminated with potentially toxic iron–cyanide complexes by some industrial activities. The influence of sulfate on the sorption of the iron–cyanide complexes ferricyanide, [Fe(CN)6]3−, and ferrocyanide, [Fe(CN)6]4−, on goethite was investigated in batch experiments. The experiments were conducted as influenced by pH and varying sulfate/iron–cyanide complex concentration ratios. Furthermore, the desorption of iron–cyanide complexes sorbed on goethite was studied using phosphate and chloride solutions as influenced by pH and anion concentration. Over the whole pH range (pH 3.5 to 8), ferricyanide and sulfate showed similar affinities for the goethite surface. The extent of ferricyanide sorption strongly depended on sulfate concentrations and vice versa. In contrast, ferrocyanide sorption was only decreased (approximately 12%) by sulfate additions at pH 3.5. Ferricyanide was completely desorbed by 1 M chloride, ferrocyanide not at all. Unbuffered phosphate solutions (pH 8.3) desorbed both iron–cyanide complexes completely. Even in 70‐fold excess, pH‐adjusted phosphate solutions could not desorb ferrocyanide completely at pH 3.5. For ferricyanide we propose a sorption mechanism that is similar to the sulfate sorption mechanism, including outer‐sphere and weak inner‐sphere surface complexes on goethite. Ferrocyanide appears to form inner‐sphere surface complexes. Additionally, we assume that ferrocyanide precipitates probably as a Berlin Blue–like phase at pH 3.5. Hence, ferrocyanide should be less mobile in the soil environment than ferricyanide or sulfate.
Soil Temperature, Nitrogen Concentration, and Residence Time Affect Nitrogen Uptake Efficiency in Citrus

ABSTRACTWe try to elucidate which environmental and soil factors control nitrogen uptake efficiency in citrus. Effects of residence time and nitrogen (N) concentration (three 500‐mL applications of 7 mg N L−1, representative of reclaimed water used for citrus irrigation in central Florida, or one 150‐mL application of 70 mg N L−1) on nitrogen uptake efficiency (NUE) of young citrus seedlings were studied. Increasing residence times from 2 to 8 h increased NUE from 36 to 82% and from 17 to 34% for high and low application frequencies, respectively. We developed a model to predict N uptake based on root density, N concentration, and soil temperature (Ts). Assuming a base temperature (Tb) of 10°C, N uptake temperature sum (UTS) = ∑(Ts − Tb)/24 (°CdN, degree day units of N uptake). To eliminate the risk of N leaching for young seedlings, minimum uptake periods of 5 and 16°CdN were required at initial soil N concentrations of 0.9 and 2.5 mg N L−1, respectively. After correcting for differences in root length, this information was then used to predict the effect of irrigation practices on N uptake from reclaimed water for mature trees. Applying 2500 mm yr−1 vs. 400 mm yr−1 reclaimed water reduced the NUE of N in this water from 100 to 63% during the summer and from 100 to 28% during the winter. Reductions in NUE at higher irrigation rates appeared to be related to N displacement below the root zone prior to complete N uptake.
Transport and Fate of Nitrate in a Glacial Outwash Aquifer in Relation to Ground Water Age, Land Use Practices, and Redox Processes
Authors: Puckett Larry J. , Cowdery Timothy K. 
Published: September 2017

ABSTRACTA combination of ground water modeling, chemical and dissolved gas analyses, and chlorofluorocarbon age dating of water was used to determine the relation between changes in agricultural practices, and NO−3 concentrations in ground water of a glacial outwash aquifer in west‐central Minnesota. The results revealed a redox zonation throughout the saturated zone with oxygen reduction occurring near the water table, NO−3 reduction immediately below it, and then a large zone of ferric iron reduction, with a small area of sulfate (SO2−4) reduction and methanogenesis (CH4) near the end of the transect. Analytical and NETPATH modeling results supported the hypothesis that organic carbon served as the electron donor for the redox reactions. Denitrification rates were quite small, 0.005 to 0.047 mmol NO−3 yr−1, and were limited by the small amounts of organic carbon, 0.01 to 1.45%. In spite of the organic carbon limitation, denitrification was virtually complete because residence time is sufficient to allow even slow processes to reach completion. Ground water sample ages showed that maximum residence times were on the order of 50 to 70 yr. Reconstructed NO−3 concentrations, estimated from measured NO−3 and dissolved N gas showed that NO−3 concentrations have been increasing in the aquifer since the 1940s, and have been above the 714 μmol L−1 maximum contaminant level at most sites since the mid‐ to late‐1960s. This increase in NO−3 has been accompanied by a corresponding increase in agricultural use of fertilizer, identified as the major source of NO−3 to the aquifer.
Spatial and Temporal Modeling of Microbial Contaminants on Grazing Farmlands
Authors: Tian Yong Q. , Gong Peng , Radke John D. , Scarborough James 
Published: September 2017

ABSTRACTThis paper introduces an integrated spatial and temporal modeling system developed mathematically for assessing microbial contaminants on animal‐grazed farmlands. The model uses fecal coliform, specifically Escherichia coli, as an indicator of fecal contamination and describes the sources, sinks, transport processes, and fate of E. coli contaminants in catchments and associated streams. Spatial features include grazing location, land topography, distance to a nearby stream, and distance through the stream network to the outlet. Temporal features are population dynamics on the land surface, in flow, and on streambeds. The model applies the principles of conservation of mass balance on two different types of pools: grid cells on land surfaces and networked stream segments. The model aims to improve the prediction of the effects of different land management strategies on the fecal contamination of waterways. This is achieved by characterizing the movement of fecal contaminants from land to streams and in‐stream mobilization. Processes of attenuation, diffusion, and transport govern the movement. Our study site is a hill land catchment with an area of 140 ha and is used exclusively for animal grazing. The model was calibrated with previous research results, and then tested using the data collected at the outlet of the catchment. The sensitivity of the model predictions was analyzed for different scenarios: effect of stock rate, attenuation rate, and flow volumes. The similar pattern between monitored and predicted E. coli concentration proved that the model captures the key features that control the population dynamics of fecal contaminants. Further experiments are required to expand the model's functionality for covering more mitigation options.
Regional Scale Variability in Sediment and Nutrient Delivery from Small Agricultural Watersheds
Authors: Verstraeten Gert , Poesen Jean 
Published: September 2017

ABSTRACTAlthough many studies have pointed out the various controlling factors of sediment and nutrient delivery on a plot or watershed scale, little is known on the spatial variability of sediment and nutrient delivery on a regional scale. This study was conducted to reveal regional variations in sediment‐associated nutrient delivery in central Belgium. Sediment deposited in 13 small retention ponds was sampled and analyzed for total phosphorus (TP), K, Mg, and Ca content. The TP content of the sediment deposits varied from 510 to 2001 mg P per kg sediment. Nutrients are predominantly fixed on the very fine sediment fraction (<16 μm), which is the reason why the nutrient trap efficiency of the ponds is only a fraction of the sediment trap efficiency. Average nutrient trap efficiency of the studied ponds varies between 4 and 31%, whereas sediment trap efficiency varies between 10 and 72%. For watersheds ranging from 7 to 4873 ha, sediment yield ranged between 1.2 and 20.6 Mg ha−1 yr−1, whereas TP export varied from 1.8 to 39.7 kg ha−1 yr−1 The observed spatial variability in nutrient losses is primarily attributed to regional variations in erosion and sediment yield values and to a far lesser degree to the spatial variations in fertilizer application. Redistribution of manure in the framework of an agricultural policy may increase the rate of nutrient delivery by ways of erosion and sediment transport.

ABSTRACTGolf course putting greens typically receive high pesticide applications to meet high quality demands. Research on pesticide fate in turf ecosystems is important to better understand the potential impact of pesticide use on the environment and human health. This research was conducted to evaluate the environmental fate of two commonly used insecticides—trichlorfon (dimethyl 2,2,2‐trichloro‐1‐hydroxyethylphosphonate) and chlorpyrifos (O,O‐diethyl O‐3,5,6‐trichloro‐2‐pyridylphosphorothioate)—in a creeping bentgrass (Agrostis palustris Huds.) putting green under customary field management practices at the University of California‐Riverside Turf Research Facility during 1996 and 1997. The two insecticides were chosen because of their difference in water solubility, persistence, adsorption, and vapor pressure. Volatilization, clipping removal, and soil residues of the insecticides were quantified and leaching was monitored using lysimeters installed in putting green plots. Results showed trichlorfon volatilization, clipping removal, and leaching loss was insignificant (in the range of 0.0001–0.06% of applied mass) both in 1996 and 1997. No significant difference in clipping removal of trichlorfon and chlorpyrifos was observed in both years (0.06 and 0.05% of applied mass for trichlorfon and 0.15 and 0.19% of applied mass for chlorpyrifos, respectively, in 1996 and 1997), but significantly lower cumulative leaching and lower soil concentration was observed in 1997 than in 1996. Volatilization loss of chlorpyrifos was not significantly different between 1996 (2.05%) and 1997 (2.71%). Volatilization loss of trichlorfon in 1996 (0.01%) was significantly higher than in 1997 (0.008%). This study demonstrated the fraction of applied insecticides leaving the turf putting greens was minimal.
