The literature review of technology adoption models and theories for the novelty technology
Authors: Lai PC
Published: August 2017

This paper contributes to the existing literature by comprehensively reviewing the concepts, applications and development of technology adoption models and theories based on the literature review with the focus on potential application for the novelty technology of single platform E-payment. These included, but were not restricted to, the Theory of Diffusion of Innovations (DIT) (Rogers, 1995), the Theory of Reasonable Action (TRA) (Fishbein and Ajzen, 1975), Theory of Planned Behavior (TPB) (Ajzen, 1985, 1991), Decomposed Theory of Planned Behaviour, (Taylor and Todd, 1995), the Technology Acceptance Model (TAM) (Davis, Bogozzi and Warshaw, 1989, Technology Acceptance Model 2 (TAM2) Venkatesh and Davis (2000) and Technology Acceptance Model 3 (TAM3) Venkatesh and Bala (2008). These reviews will shed some light and potential applications for technology applications for future researchers to conceptualize, distinguish and comprehend the underlying technology models and theories that may affect the previous, current and future application of technology adoption.
Exploring Vital Sign Data Quality in Electronic Health Records with Focus on Emergency Care Warning Scores
Authors: Chen Rong , Blomqvist Hans , Koch Sabine , Skyttberg Niclas
Published: August 2017

Background: Computerized clinical decision support and automation of warnings have been advocated to assist clinicians in detecting patients at risk of physiological instability. To provide reliable support such systems are dependent on high-quality vital sign data. Data quality depends on how, when and why the data is captured and/or documented.

Objectives: This study aims to describe the effects on data quality of vital signs by three different types of documentation practices in five Swedish emergency hospitals, and to assess data fitness for calculating warning and triage scores. The study also provides reference data on triage vital signs in Swedish emergency care.

Methods: We extracted a dataset including vital signs, demographic and administrative data from emergency care visits (n=335027) at five Swedish emergency hospitals during 2013 using either completely paper-based, completely electronic or mixed documentation practices. Descriptive statistics were used to assess fitness for use in emergency care decision support systems aiming to calculate warning and triage scores, and data quality was described in three categories: currency, completeness and correctness. To estimate correctness, two further categories –plausibility and concordance –were used.

Results: The study showed an acceptable correctness of the registered vital signs irrespectively of the type of documentation practice. Completeness was high in sites where registrations were routinely entered into the Electronic Health Record (EHR). The currency was only acceptable in sites with a completely electronic documentation practice.

Conclusion: Although vital signs that were recorded in completely electronic documentation practices showed plausible results regarding correctness, completeness and currency, the study concludes that vital signs documented in Swedish emergency care EHRs cannot generally be considered fit for use for calculation of triage and warning scores. Low completeness and currency were found if the documentation was not completely electronic.

Air pollution near arterial roads: An experimental and modelling study
Authors: Huertas Cardozo José Ignacio , Prato Sánchez Daniel Fernando
Published: August 2017

Abstract. Aiming to advance in the understanding of pollutant dispersion near arterial roads, we measured, simultaneously, meteorological parameters, emission mass rates and TSP, PM10 and PM2.5 concentrations at several locations downwind two roads, located on a flat region without any other source of pollutants. We also implemented on a state of the art commercial CFD software, an air quality model to simulate the dispersion of solid and gas-phase pollutants emitted from arterial roads. Numerical results of long-term averages and daily measurements of particle concentration showed high correlation with experimental measurements (R2 > 0.76). We found that the plots of pollutants concentration vs distance to the road edge describe a unique curve when expressed in terms of non-dimensional numbers and that this curve is well described by a beta function. Profiles of vertical concentration sketch an exponential function at the road edge, an S shape downwind and a flat shape far from the road. Particles exhibit a Rosin Rambler size distribution with average diameter of ~ 7 μm. This distribution remains unaltered downwind from the road, which implies that at any location, PM10 and PM2.5 concentrations are a constant fraction of TPS concentration. Experimental data confirmed this observation. Previous results can be used to determine the size of the area impacted by roads, identify mitigating and adaptive countermeasures, and to improve the accuracy of vehicular emission factors.

Published: August 2017

Abstract. The novel aircraft optical cloud probe PHIPS-HALO has been developed to establish clarity regarding the fundamental link between the microphysical properties of single atmospheric ice particles and their appropriated angular light scattering function. After final improvements have been implemented to the polar nephelometer part and the acquisition software of PHIPS-HALO, the instrument was comprehensively characterized in the laboratory and was deployed in two aircraft missions targeting cirrus and Arctic mixed-phase clouds. This work demonstrates the proper function of the instrument under aircraft conditions and highlights the uniqueness, quality, and limitations of the data that can be expected from PHIPS-HALO in cloud-related aircraft missions.
The sensitivity of estuarine aragonite saturation state and pH to the carbonate chemistry of a freshet-dominated river
Authors: Moore-Maley Benjamin L. , Ianson Debby , Allen Susan E.
Published: August 2017

Abstract. Ocean acidification threatens to reduce pH and aragonite saturation state (ΩA) in estuaries, potentially damaging their ecosystems. However, the impact of highly variable river total alkalinity (TA) and dissolved inorganic carbon (DIC) on pH and ΩA in these estuaries is unknown. We assess the sensitivity of estuarine surface pH and ΩA to river chemistry using a 1-dimensional, biogeochemical-coupled model of the Strait of Georgia on the Canadian Pacific coast and generalize the results in the context of global rivers. The productive Strait of Georgia estuary has a large, seasonally variable freshwater input from the glacially fed, undammed Fraser River. Analyzing TA and pH observations from this river and its estuary, we find that the Fraser is moderately alkaline (TA 500–1350 μmol kg−1) but relatively DIC-rich, especially during winter (low flow). Model results show that estuarine pH and ΩA, while sensitive to freshwater DIC and TA, do not vary in synchrony. Instead, rivers with high DIC and TA produce lower estuarine pH due to an increased estuarine DIC : TA ratio, but higher estuarine ΩA because of DIC contributions to the carbonate ion. This estuarine pH sensitivity decreases with increasing mean river TA, but the zone of maximum pH sensitivity also moves to higher salinity which could impact a larger areal extent of the estuary. Many temperate rivers, such as the Fraser, are expected to experience weaker freshets and stronger winter flows under climate change, reducing the extent of the river plume and the impact of river chemistry in much of the estuary. However, increasing carbon in rivers will move the highest sensitivity zone to higher salinities that cover larger areas under present-day flow regimes.
A method to employ the spatial organization of catchments into semi-distributed rainfall–runoff models
Authors: Oppel Henning , Schumann Andreas
Published: August 2017

Abstract. A distributed or semi-distributed deterministic hydrological model should consider the hydrologically most relevant catchment characteristics. These are heterogeneously distributed within a watershed but often interrelated and subject to a certain spatial organization which results in archetypes of combined characteristics. In order to reproduce the natural rainfall–runoff response the reduction of variance of catchment properties as well as the incorporation of the spatial organization of the catchment are desirable. In this study the width-function approach is utilized as a basic characteristic to analyse the succession of catchment characteristics. By applying this technique we were able to assess the context of catchment properties like soil or topology along the streamflow length and the network geomorphology, giving indications of the spatial organization of a catchment. Moreover, this information and this technique have been implemented in an algorithm for automated sub-basin ascertainment, which included the definition of zones within the newly defined sub-basins. The objective was to provide sub-basins that were less heterogeneous than common separation schemes. The algorithm was applied to two parameters characterizing the topology and soil of four mid-European watersheds. Resulting partitions indicated a wide range of applicability for the method and the algorithm. Additionally, the intersection of derived zones for different catchment characteristics could give insights into sub-basin similarities. Finally, a HBV96 case study demonstrated the potential benefits of modelling with the new subdivision technique.

Published: August 2017

Physical activity is an effective method for managing depressive symptoms, and web-based interventions may be an effective tool for promoting physical activity within this population. People with depressive symptoms may experience condition-specific facilitators and barriers to be considered when developing physical activity interventions. This study provides insight into web-based physical activity intervention preferences and physical activity motivation of people with depressive symptoms. This study was part of a larger trial of a web-based physical activity intervention for people with depressive symptoms. Thematic analysis of participants’ (N = 20) written responses to open-ended survey questions was conducted. Preferences for web-based intervention features included social forums, self-monitoring, suggestions for types of physical activity in different circumstances and information targeted to people with depressive symptoms. When discussing physical activity motivation instrumental beliefs (i.e., beliefs of the benefits and cost of physical activity) and controllability (i.e., whether the behaviour is under their control) were discussed. Additionally, people reported condition-specific barriers of physical activity such as depressive symptoms of apathy, worthlessness, and pain. Further research is needed to test the effectiveness of web-based physical activity interventions targeting people with depressive symptoms, which incorporates these findings.

Objetivo: avaliar, in vitro, a variação de cor e dureza de três materiais restauradores (3M ESPE): Ketac Molar Easymix (KME); Vitremer (VT) e resina composta Filtek Z250 (Z250) após o clareamento com peróxido de carbamida a 37% (PC37- Whiteness Super) e peróxido de hidrogênio a 35% (PH35- Whiteness HP Maxx). Materiais e método: foram confeccionados 108 corpos de prova (CP), sendo 36 para cada material, avaliados inicialmente (baseline) e após cada aplicação dos agentes clareadores realizadas em subseqüentes 7 períodos, ou seja, após 1, 7, 14, 21, 28, 35 e 42 dias. As avaliações colorimétricas (coordenadas CIELAB) dos CP foram realizadas usando um espectrofotômetro (Easyshade, Vita Zahnfabrik, Bad Sackingen, Alemanha) sob fundo branco e em ambiente clínico. Para a avaliação da dureza (H), usou-se um durômetro (Pantec HVS 10, Panambra Ind. e Téc. SA, São Paulo, SP Brasil) com penetrador tipo Vickers. Os resultados das diferenças de cor (ΔE*ab), diferenças de L* (ΔL*) e H foram calculados e avaliados estatisticamente usando análise de variância (ANOVA) e as diferenças avaliadas pelo teste Tukey (α=0,05). Resultados: após o clareamento, houve alterações significativas no valor de ΔE*ab para os dois materiais a base de ionômero de vidro (KME e VT), com ambos os clareadores (PC37 e PH35) mostrando efeito similar para cada material. Não houve diferença na H dos materiais. Conclusão: após 42 dias, agentes clareadores alteraram a cor dos materiais ionoméricos e não alteraram a dureza dos materiais testados.
Pulmonary embolism four days after interruption of therapy with rivaroxaban
Authors: Göndör Gabor , Stöllberger Claudia
Published: August 2017

Thrombosis after cessation of anticoagulation, also named rebound thrombosis, is a matter of concern and controversy. There are only few published data about occurrence of rebound thrombosis associated with non-vitamin K-antagonist oral anticoagulant drugs (NOACs). We report on a 58-year-old male with paroxysmal atrial fibrillation (AF) with a CHA2DS2VASC score of 4 who developed central pulmonary embolism four days after interruption of rivaroxaban because of parotid surgery. He had received 40 mg enoxaparin/d. The parotid gland was partially resected within 6 hours without blood loss. Pulmonary embolism and AF occurred on the first postoperative day. He recovered with low-molecular-weight heparin in therapeutic dosages and amiodarone and was discharged with phenprocoumon. The relevance of a rivaroxaban rebound phenomenon, manifesting as arterial embolism, stroke or venous thromboembolism should be clarified. It should be assessed if rebound-phenomena also exist for the NOACs dabigatran, apixaban and edoxaban. Thus, the randomized trials and registries investigating patients with AF or venous thromboembolism should be re-analysed and, based on these data, recommendations should be developed for situations in which NOAC-therapy has to be interrupted or ceased.
Numerical Simulations with the Galerkin Least Squares Finite Element Method for the Burgers' Equation on the Real Line
Authors: Konzen Pedro Henrique de Almeida , Azevedo F S , Sauter E , Zingano P R A
Published: August 2017

In this work we present an efficient Galerkin least squares finite element scheme to simulate the Burgers' equation on the whole real line and subjected to initial conditions with compact support. The numerical simulations are performed by considering a sequence of auxiliary spatially dimensionless Dirichlet's problems parameterized by its numerical support $\tilde{K}$. Gaining advantage from the well-known convective-diffusive effects of the Burgers' equation, computations start by choosing $\tilde{K}$ so it contains the support of the initial condition and, as solution diffuses out, $\tilde{K}$ is increased appropriately. By direct comparisons between numerical and analytic solutions and its asymptotic behavior, we conclude that the proposed scheme is accurate even for large times, and it can be applied to numerically investigate properties of this and similar equations on unbounded domains.

Published: August 2017

A series of temperature-sensitive polyurethanes (TSPUs) with polytetrahydrofuran glycol (PTMG), poly(ethylene glycol) (PEG) and maleic anhydride modified castor oil (MCO) as soft segments were prepared in this paper. The morphology of the temperature-sensitive polyurethane films was characterised by SEM, DSC and WAXD. SEM studies were also carried out to investigate the surface structure of coated and uncoated fabrics. The water vapour permeability of the coated and uncoated fabrics were measured as well. The results showed that a nonporous TSPU layer was formed on the coated fabric surface. The tailor -made TSPUs had one to three soft segment crystal melting point temperatures, with the the lower peak temperature Tpm1 belonging to the soft segment PTMG and the higher peak temperature Tpm2 to the hydropilic soft segment PEG2000. The water vapour permeability of TSPUs coated fabrics increased with an increase in PEG2000 concentration and PEG molecular weight, but decreased with an increase in the hard segment content, and triggered around the soft segment crystal melting point temperature of TSPUs.

Published: August 2017

Electrospinning is an effective technique for fabricating submicron to nanoscale fibers from synthetic polymer as well as natural proteins. In this study, multiwalled carbon nanotubes (MWNTs) were embedded via electrospinning by adding MWNTs into the spinning dope, and found to be well aligned along the fiber axis in the silk fibroin nanofibers. The morphology and microstructure of the electrospun nanofibers were characterised using a field emission scanning electron microscope (FESEM) and Transmission electron microscopy (TEM). X-ray diffraction (XRD) and TG-DTA were used to study the crystal structure of the silk/MWNTs composite nanofibres, carried out to alter the strength, toughness and electrical conductivity of silk nanofibers by adding a small amount of MWNTs. The electrospun random silk mats with 1% MWNTs had a Young’s modulus, ultimate tensile strength and strain of 107.46 ± 9.15MPa, 9.94 ± 1.2MPa and 9.25 ± 1.5%, respectively, and electrical conductivity increased to 1.2×10-4S/cm. The silk/MWNTs composite nanofibres could potentially be applied in nerve repair materials owing to their excellent mechanical properties and electrical conductivity.
Filtration Properties of Nonwoven Structures with Superabsorbents for Respiratory Protective Devices
Authors: Brochocka Agnieszka
Published: August 2017

The paper presents a study of the protective and functional properties of nonwoven structures, such as penetration by solid and liquid aerosols, airflow resistance, and air moisture sorption capacity. Nonwovens were modified by the introduction of electrostatic charges in the structure of polymer fibers and by the addition of a superabsorbent polymeric (SAP) directly to the fiber-forming area in a melt-blown process. The resulting materials (outer nonwovens containing SAP of different grain sizes and filtering nonwovens with and without electrostatic charges) had varied morphological structures. The materials developed were characterised by high filtering efficiency at low airflow resistance and good moisture sorption ability. The study proved the possibility to apply nonwoven structures containing SAP in respiratory protective equipment used in harsh work environments at high temperature and relative humidity. The materials fabricated were found to improve hygienic comfort.

Published: August 2017

In the process of producing covered yarn, a single outer wrapping yarn forms a balloon when it rotates at high speed. In this work, we used a mathematical model of a balloon formed by polyamide,which is a common outer wrapping yarn, and verified its feasibility with a group of experimental data. The effects of yarn tension, rotation speed, balloon height and turntable radius on the balloon shape were analysed and the correctness simultaneously demonstrated.
Porosity of Knitted Fabrics in the Aspect of Air Permeability - Discussion of Selected Assumptions
Authors: Havlová Marie , Špánková Jana
Published: August 2017

The main focus of this paper is to look into the relationship between the structure and air permeability of single jersey knitted fabric – especially verifying some basic assumptions. First, if it is possible to neglect the permeability of yarns themselves when we evaluate that of knits, and second, if yarn hairiness plays a significant role when we evaluate the relationship between air permeability and the porosity of knits. Theoretical calculations and experiments which were performed using an analysis of microscopic images of the structure of textile materials are used for the determination of inter-yarn and intra-yarn porosity. The paper aims to show t hat the characteristic dimension of inter-yarn pores is significantly higher than that of intra-yarn pores, and also that the values of inter-yarn porosity measured using image analysis methods with hairiness and after the removal of hairiness are statistically significantly different. The correlation coefficients for the porosity values measured and calculated are very high.
Meta-discourse as a Source for Exploring the Professional Image(s) of Conference Interpreters
Authors: Diriker Ebru
Published: August 2017

Simultaneous conference interpreters, like all other professionals, operate with a ’professional identity’ that shapes, and is shaped, by the way a variety of actors and institutions inside and outside the ﬁeld of activity see and describe the profession(al). Departing from the assumption that the professional image of conference interpreters is largely (meta-)discursive in nature, this paper analyzes how various actors and institutions depict conference interpreting and interpreters in their discourses, whether the images propagated converge or diverge from each other, and what the divergences may imply for the profession and the professional.
Going Localised - Getting Recognised. The Interplay of the Institutional and the Experienced Status of Translators in the European Commission
Authors: Koskinen Kaisa
Published: August 2017

This paper explores how and whether the different institutional and organisational contexts affect translators’ professional activities and professional identities. The site researched is the European Commission, where the changing political impetus has recently instigated a new role for some of the translators. For them, the institutional framework has thus changed substantially. This presents an opportunity to research how institutionally expressed status affects the status as experienced by the translators themselves. The data consists of institutional documents as well as interview and observation data from two different settings, a traditional translation unit in Luxembourg (2004) and the local representation of the European Commission in Helsinki (2008). The results indicate that the institutional and physical space occupied by the translators can drastically change their experienced status and motivation even within a single organisational setting.
The Community Interpreter: A Question of Role
Authors: Jacobsen Bente
Published: August 2017

Studies of conference interpreting and community interpreting differ from studies of the translation of written texts in their object of study. Thus, unlike studies of written translations, studies of interpreting have traditionally focused on the individual performing the translation, i.e. the interpreter, as opposed to interpreting. Moreover, whereas research in conference interpreting has traditionally centred on issues connected with the process of interpreting, research in community interpreting has traditionally centred on role perceptions and expectations among users of interpreting services and interpreting practitioners. This article presents an overview of relevant community interpreting literature and shows how the topic of interpreter role has always dominated the ﬁeld.
Intercultural Alternatives - two Nordic Books on Intercultural Communication
Authors: Tange Hanne
Published: August 2017

The article compares two recent Nordic anthologies on intercultural communication. One volume, Askehave/Norlyk’s Meanings and Messages (2006) addresses the topic from a speciﬁc, business-oriented viewpoint, whereas the second collection, Dahl et al.’s Bridges of Understanding (2006) builds on a broader deﬁnition of the subject. This reﬂects on the contents, with the former relying on business as a central point of reference, while the latter highlights theoretical differences and interdisciplinarity. The review assesses the books in relation to the teaching of intercultural communication, discussing editorial aims, theoretical outlook, approach to culture, and accessibility. It concludes that the books are important because of the way they attempt to communicate Nordic research, but also that they do not quite meet the requirements that this reader makes from course literature in intercultural communication.

Les constructions siamoises en français et dans cinq autres langues européennes. Étude sur la comparative corrélative
Authors: Stage Lilian
Published: August 2017

This article discusses the comparative correlative constructions in French and ﬁve other European languages. A comparative correlative construction is a binary structure whose two parts are conjoined as Siamese twins (to use the ﬁne metaphor invented by Savelli, a French linguist). The most striking feature of this construction is the fronting of the comparatives in two clauses which are interdependent and inseparable, though at ﬁrst glance no clear relation can be seen, neither in French nor in English. It is hoped that this study of six European languages will contribute to an elucidation of the structuring of the two clauses and the relation between the two parts as well as the meaning they convey.
Rotina de ordenha eficiente para produção de leite de alta qualidade
Authors: Leonel Gonçalves Juliano , Tomazi Tiago , Veiga dos Santos Marcos
Published: August 2017

A ordenha das vacas é uma das atividades mais importantes de uma propriedade leiteira, devido a três aspectos principais: é nessa hora que o produtor coleta o leite, produto resultante de todos os demais esforços realizados na propriedade; é no momento da ordenha que existe alto risco de as vacas contraírem a mastite; é o momento de alto risco de contaminação microbiana do leite. A produção de leite de alta qualidade depende das condições higiênicas das vacas durante o processo de ordenha, do programa de sanidade do úbere e do resfriamento eficiente do leite cru. Durante o processo de ordenha, alguns dos fatores críticos que influenciam o risco de novas infecções intramamárias são: limpeza do úbere e tetos, manejo das vacas e funcionamento do equipamento de ordenha. Diante deste cenário, o objetivo dessa revisão é descrever sucintamente os principais fatores associados com um manejo de ordenha eficiente para produção de leite de alta qualidade.

O objetivo desta revisão é trazer informações atualizadas sobre o papel dos fatores imunes do colostro, além das imunoglobulinas (Igs), na proteção direta ou indireta dos bezerros. Os recém-nascidos são hipogamaglobulinêmicos e imunossuprimidos, além de possuírem sistema imune adaptativo näive. Desta forma, é consensual que a colostragem é prioridade no sistema de criação de bezerras, entretanto as novas descobertas sobre a atuação dos leucócitos maternos e seus subprodutos (citocinas),  amplificando os mecanismos da resposta imunes inata e adaptativa, tem gerado muitas discussões no meio científico internacional. Além disso, as recentes descobertas sobre o microbioma humano têm sugerido que o processo de amamentação é fundamental para a transferência vertical de Lactobacillus e Bifidobacterium, microrganismos que desempenham um importante papel no desenvolvimento da imunidade de mucosas e saúde intestinal.  Em geral, estas descobertas possuem aplicabilidade e trazem reflexões sobre o manejo tradicionalmente empregado na criação de bezerras, considerando-se o contato entre a vaca e recém-nascido, colostragem, sistema de aleitamento, higienização e desinfecção ambiental.

Statistical methods of fracture characterization using acoustic borehole televiewer log interpretation
Authors: Massiot Cécile , Townend John , Nicol Andrew , McNamara David D.
Published: August 2017

Acoustic borehole televiewer (BHTV) logs provide measurements of fracture attributes (orientations, thickness, and spacing) at depth. Orientation, censoring, and truncation sampling biases similar to those described for one‐dimensional outcrop scanlines, and other logging or drilling artifacts specific to BHTV logs, can affect the interpretation of fracture attributes from BHTV logs. K‐means, fuzzy K‐means, and agglomerative clustering methods provide transparent means of separating fracture groups on the basis of their orientation. Fracture spacing is calculated for each of these fracture sets. Maximum likelihood estimation using truncated distributions permits the fitting of several probability distributions to the fracture attribute data sets within truncation limits, which can then be extrapolated over the entire range where they naturally occur. Akaike Information Criterion (AIC) and Schwartz Bayesian Criterion (SBC) statistical information criteria rank the distributions by how well they fit the data. We demonstrate these attribute analysis methods with a data set derived from three BHTV logs acquired from the high‐temperature Rotokawa geothermal field, New Zealand. Varying BHTV log quality reduces the number of input data points, but careful selection of the quality levels where fractures are deemed fully sampled increases the reliability of the analysis. Spacing data analysis comprising up to 300 data points and spanning three orders of magnitude can be approximated similarly well (similar AIC rankings) with several distributions. Several clustering configurations and probability distributions can often characterize the data at similar levels of statistical criteria. Thus, several scenarios should be considered when using BHTV log data to constrain numerical fracture models.
Evidence for tectonic, lithologic, and thermal controls on fracture system geometries in an andesitic high‐temperature geothermal field
Authors: Massiot Cécile , Nicol Andrew , McNamara David D. , Townend John
Published: August 2017

Analysis of fracture orientation, spacing, and thickness from acoustic borehole televiewer (BHTV) logs and cores in the andesite‐hosted Rotokawa geothermal reservoir (New Zealand) highlights potential controls on the geometry of the fracture system. Cluster analysis of fracture orientations indicates four fracture sets. Probability distributions of fracture spacing and thickness measured on BHTV logs are estimated for each fracture set, using maximum likelihood estimations applied to truncated size distributions to account for sampling bias. Fracture spacing is dominantly lognormal, though two subordinate fracture sets have a power law spacing. This difference in spacing distributions may reflect the influence of the andesitic sequence stratification (lognormal) and tectonic faults (power law). Fracture thicknesses of 9–30 mm observed in BHTV logs, and 1–3 mm in cores, are interpreted to follow a power law. Fractures in thin sections (∼5 μm thick) do not fit this power law distribution, which, together with their orientation, reflect a change of controls on fracture thickness from uniform (such as thermal) controls at thin section scale to anisotropic (tectonic) at core and BHTV scales of observation. However, the ∼5% volumetric percentage of fractures within the rock at all three scales suggests a self‐similar behavior in 3‐D. Power law thickness distributions potentially associated with power law fluid flow rates, and increased connectivity where fracture sets intersect, may cause the large permeability variations that occur at hundred meter scales in the reservoir. The described fracture geometries can be incorporated into fracture and flow models to explore the roles of fracture connectivity, stress, and mineral precipitation/dissolution on permeability in such andesite‐hosted geothermal systems.

With recognition of the biological importance of hydrogen sulfide (H2S), we present a simple and effective fluorescent probe for H2S using a Tb3+ coordination polymer–Cu2+ compound (DPA/Tb/G–Cu2+). Dipicolinic acid (DPA) and guanosine (G) can coordinate with Tb3+ to form a macromolecular coordination polymer (DPA/Tb/G). DPA/Tb/G specifically binds to Cu2+ in the presence of coexisting cations, and obvious fluorescence quenching is observed. The quenched fluorescence can be exclusively recovered upon the addition of sulfide, which is measured in the mode of time‐resolved fluorescence. The fluorescence intensities of the DPA/Tb/G–Cu2+ compound enhance linearly with increasing sulfide concentrations from 1 to 30 μM. The detection limit for sulfide in aqueous solution is estimated to be 0.3 μM (at 3σ). The DPA/Tb/G–Cu2+ compound was successfully applied to sense H2S in human serum samples and exhibited a satisfactory result. It displays some desirable properties, such as fast detection procedure, high selectivity and excellent sensitivity. This method is very promising to be utilized for practical detection of H2S in biological and environmental samples.
Sea level rise may increase extinction risk of a saltmarsh ontogenetic habitat specialist

Specialist species are more vulnerable to environmental change than generalist species. For species with ontogenetic niche shifts, specialization may occur at a particular life stage making those stages more susceptible to environmental change. In the salt marshes in the northeast U.S., accelerated sea level rise is shifting vegetation patterns from flood‐intolerant species such as Spartina patens to the flood‐tolerant Spartina alterniflora. We tested the potential impact of this change on the coffee bean snail, Melampus bidentatus, a numerically dominant benthic invertebrate with an ontogenetic niche shift. From a survey of eight marshes throughout the northeast U.S., small snails were found primarily in S. patens habitats, and large snails were found primarily in stunted S. alterniflora habitats. When transplanted into stunted S. alterniflora, small snails suffered significantly higher mortality relative to those in S. patens habitats; adult snail survivorship was similar between habitats. Because other habitats were not interchangeable with S. patens for young snails, these results suggest that Melampus is an ontogenetic specialist where young snails are habitat specialists and adult snails are habitat generalists. Temperature was significantly higher and relative humidity significantly lower in stunted S. alterniflora than in S. patens. These data suggest that thermal and desiccation stress restricted young snails to S. patens habitat, which has high stem density and a layer of thatch that protects snails from environmental stress. Other authors predict that if salt marshes in the northeast U.S. are unable to migrate landward, sea level rise will eliminate S. patens habitats. We suggest that if a salt marsh loses its S. patens habitats, it will also lose its coffee bean snails. Our results demonstrate the need to consider individual life stages when determining a species’ vulnerability to global change.

There are many varieties of gastroenteritis viruses, of which norovirus (NoV) accounts for over 90% of the viral food poisoning incidents in Japan. However, protocols for rapidly identifying other gastroenteritis viruses need to be established to investigate NoV‐negative cases intensively. In this study, a multiplex real‐time PCR assay targeting rotavirus A, rotavirus C, sapovirus, astrovirus, adenovirus, and enterovirus was developed using stool samples collected from gastroenteritis patients between 2010 and 2013 in Fukui Prefecture, Japan. Of the 126 samples collected sporadically from pediatric patients with suspected infectious gastroenteritis, 51 were positive for non‐NoV target viruses, whereas 27 were positive for NoV, showing a high prevalence of non‐NoV viruses in pediatric patients. In contrast, testing in 382 samples of 58 gastroenteritis outbreaks showed that non‐NoV viruses were detected in 13 samples, with NoV in 267. Of the 267 NoV‐positive patients, only two were co‐infected with non‐NoV target viruses, suggesting that testing for non‐NoV gastroenteritis viruses in NoV‐positive samples was mostly unnecessary in outbreak investigations. Given these results, multiplex real‐time PCR testing for non‐NoV gastroenteritis viruses, conducted separately from NoV testing, may be helpful to deal with two types of epidemiological investigations, regular surveillance of infectious gastroenteritis and urgent testing when gastroenteritis outbreaks occur.

Seven hydroxyanthraquinones were successfully separated from the traditional Chinese medicinal herb Cassiae semen by conventional and pH‐zone‐refining countercurrent chromatography with an environmentally friendly biphasic solvent system, in which elution–extrusion mode was investigated for pH‐zone‐refining countercurrent chromatography for the first time. A two‐phase solvent system composed of n‐hexane/ethyl acetate/ethanol/water (5:3:4:4, v/v/v/v) was used for the conventional countercurrent chromatography while the same system with a different volume ratio n‐hexane/ethyl acetate/ethanol/water (3:5:2:6, v/v/v/v) was used for pH‐zone‐refining countercurrent chromatography, in which 20 mmol/L of trifluoroacetic acid was added in the organic phase as a retainer and 15 mmol/L of ammonia was added to the aqueous phase as an eluter. A 400 mg crude sample could be well separated by pH‐zone‐refining countercurrent chromatography, yielding 53 mg of aurantio‐obtusin, 40 mg of chryso‐obtusin, 18 mg of obtusin, 24 mg of obtusifolin, 10 mg of emodin, and 105 mg of the mixture of chrysophanol and physcion with a purity of over 95.8, 95.7, 96.9, 93.5, 97.4, 77.1, and 19.8%, as determined by high‐performance liquid chromatography. Furthermore, the difference in elution sequence between conventional and pH‐zone‐refining mode was observed and discussed.

Background

Prostate cancer (PCa) diagnostics would greatly benefit from more accurate, non‐invasive techniques for the detection of clinically significant disease, leading to a reduction of over‐diagnosis and over‐treatment. The aim of this study was to determine the association between a novel urinary biomarker‐based risk score (SelectMDx), multiparametric MRI (mpMRI) outcomes, and biopsy results for PCa detection.

Methods

This retrospective observational study used data from the validation study of the SelectMDx score, in which urine was collected after digital rectal examination from men undergoing prostate biopsies. A subset of these patients also underwent a mpMRI scan of the prostate. The indications for performing mpMRI were based on persistent clinical suspicion of PCa or local staging after PCa was found upon biopsy. All mpMRI images were centrally reviewed in 2016 by an experienced radiologist blinded for the urine test results and biopsy outcome. The PI‐RADS version 2 was used.

Results

In total, 172 patients were included for analysis. Hundred (58%) patients had PCa detected upon prostate biopsy, of which 52 (52%) had high‐grade disease correlated with a significantly higher SelectMDx score (P < 0.01). The median SelectMDx score was significantly higher in patients with a suspicious significant lesion on mpMRI compared to no suspicion of significant PCa (P < 0.01). For the prediction of mpMRI outcome, the area‐under‐the‐curve of SelectMDx was 0.83 compared to 0.66 for PSA and 0.65 for PCA3. There was a positive association between SelectMDx score and the final PI‐RADS grade. There was a statistically significant difference in SelectMDx score between PI‐RADS 3 and 4 (P < 0.01) and between PI‐RADS 4 and 5 (P < 0.01).

Conclusions

The novel urinary biomarker‐based SelectMDx score is a promising tool in PCa detection. This study showed promising results regarding the correlation between the SelectMDx score and mpMRI outcomes, outperforming PCA3. Our results suggest that this risk score could guide clinicians in identifying patients at risk for significant PCa and selecting patients for further radiological diagnostics to reduce unnecessary procedures.
Quality of life of patients with inflammatory bowel disease

Published: August 2017

Rationale Crohn's disease and non-specific ulcerative colitis are part of inflammatory bowel diseases. They have a chronic evolution, leading to important repercussions on patients’ quality of life. Measuring this subjective parameter requires an evaluation tool in clinical trials and health programs. The “Inflammatory Bowel Disease Questionnaire” is an American instrument of McMaster University, which had its reproducibility and validity determined in studies in other countries as a measure of the quality of life in IBD.

Objective To evaluate the quality of life of patients with inflammatory bowel disease through the Inflammatory Bowel Disease Questionnaire, and to correlate the results with sociodemographic data of the patients.

Methods This is a prospective cross-sectional study carried out with 58 patients; the patients’ follow-up was conducted at the outpatient clinic of Coloproctology.

Results Among the 58 patients evaluated, 70.1% had DC, 62.1% were women, the mean age was 46.08 years, 96.6% were non-smokers, and 24.1% were submitted to surgery for the underlying disease. 43% were in a combination therapy scheme, 44% in monotherapy, and 12% were not using medication. Significant change in quality of life was observed in patients taking prednisone.

Conclusion The patients with better quality of life are those who were taking prednisone. There was no other correlation with significance in the patients’ quality of life.
