Harmonization of External Quality Assessment Schemes and their role – clinical chemistry and beyond
Authors: Ceriotti Ferruccio , Cobbaert Christa 
Published: May 2018

Abstract
The article tries to reply to the following three questions: Are External Quality Assessment Schemes (EQAS) really fit for purpose? Are all schemes equivalent and sufficiently harmonized? Is the role of EQAS similar and necessary in all branches of laboratory medicine? Although the reply to the first two questions is, unfortunately, negative for several reasons (lack of commutable material with reference method values, EQAS with different scopes, etc.), the reply to the third one is positive: EQAS are a necessary source of information on trueness and accuracy and must be fully developed for all the branches of the clinical laboratory.
Modelling world energy security data from multinomial distribution by generalized linear model under different cumulative link functions
Authors: Iyit Neslihan 
Published: May 2018

AbstractEnergy securityis one of the major components of energy sustainability in the world’s energy performance. In this study,energy securityis taken as an ordinal response variable coming from the multinomial distribution with the energy grade levelsA,B,C, andD. Thereafter, the worldenergy securitydata is tried to be statistically modelled by usinggeneralized linear model (GLM)approach for the ordinal response variable under different cumulative link functions. The cumulative link functions comparatively used in this study are cumulative logit, cumulative probit, cumulative complementary log-log, cumulative Cauchit, and cumulative negative log-log. In order to avoid a multicollinearity problem in the data structure, principal component analysis (PCA) technique is integrated with theGLMapproach for the ordinal response variable. In this study, statistically, the importance of determining the best cumulative link function on the accuracy of parameter estimates, confidence intervals, and hypothesis tests in theGLMfor the multinomially distributed response variable is highlighted. In terms of energy evaluation, by usingcumulative logitas the best cumulative link function,energy sources consumptions,electricity productions from nuclear energy,natural gas,oil,coal,and hydroelectric,energy use per capita and energy importsare found to have statistically significant effects onenergy securityin the world’s energy performance.

Published: May 2018

Abstract
The present work aimed to investigate the effect of crude oil on the rate of diffusion-controlled corrosion of copper pipeline in acidified dichromate under fully developed flow. To achieve this goal, various parameters were investigated, such as crude oil percentage volume (%), flow physical properties, active height of the copper pipeline, flow velocity, and the presence of Triton X-100. The results of our study revealed that the rate of copper pipeline inner-wall corrosion increases with the increase of crude oil percentage volume and flow velocity. On the other hand, the active height of copper pipeline has no significant effect on the corrosion rate. In addition, the presence of crude oil and Triton has a synergistic effect on retarding the corrosion rate. The inhibition efficiency of Triton X-100 varied from 4.4% to 41.3% depending on its concentration and flow velocity. Polarization curves indicated that the corrosion kinetics is diffusion controlled in acidified dichromate and in the presence of crude oil and Triton X-100. However, the corrosion kinetics is mixed controlled in the presence of acidified dichromate and crude oil. Correlation of the present mass transfer data using dimensionless analysis led to the following dimensionless equation: Sh=0.58Re
0.5
Sc
0.33, with the conditions 677<Sc<1490 and 3699<Re<30,874. The present work highlighted the practical importance of the present mass transfer correlation in the design and protection against corrosion of pipelines due to crude oil transportation.

Abstract

Background:
Relapsing polychondritis (RP) is a rare autoimmune disorder, and myelodysplastic syndrome (MDS) is accompanied by RP at variable rates. Herein, we report a case with RP and MDS who responded dramatically to 5-azacitidine for MDS.

Case presentation:
With conventional immunosuppressive treatment, our patient had several episodes of different side effects, including infections. With the diagnosis of MDS and initiation of azacitidine treatment, all the manifestations of RP disappeared, and remission was achieved for MDS. Although he had relapses of either RP or MDS after several years of azacitidine treatment, all relapses were controlled well with the initiation of azacitidine treatment every time.

Conclusions:
Azacitidine should be kept in mind as a treatment option for RP patients with MDS.

AbstractDr Chao-Chien Jan, Research Geneticist with the USDA-Agricultural Research Service (USDA-ARS), Red River Valley Agricultural Research Center, Northern Crop Science Laboratory, Sunflower and Plant Biology Research Unit, Fargo, ND retired January, 2017 after 35 years of dedicated service. He began his research career in 1974 after receiving his Ph.D. in genetics from the University of California, Davis, CA, working with wheat. He was a postdoctoral Research Biologist at the Cancer Research Institute, University of California, San Francisco in 1975. From 1976 to 1981 he was a postdoctoral Research Agronomist, Department of Agronomy and Range Science, UC, Davis, CA. working on wheat. In 1981, Dr Jan joined the U.S. Department of Agriculture, Agricultural Research Service (USDA-ARS) as a Research Geneticist at the Rice and Oilseed Unit at Davis, CA with an emphasis on cytogenetics, working on sunflower (Helianthus annuus) crop wild relatives (CWR) for the improvement of the sunflower crop. The sunflower program at Davis, CA was closed in 1984, and he was transferred to the USDA-ARS Sunflower Unit in Fargo, ND where he spent the rest of his career working on sunflower CWR. Dr Jan’ research contributed significantly to the ability to utilize the genetic diversity of the 53 species of wild sunflowers, especially in the areas of germination, use of embryo culture and chromosome doubling to overcome embryo abortion and fertility problems. His pioneering research in interspecific hybridization, cytoplasmic male sterility and fertility restoration, cytogenetic stocks, disease resistance and mutation opened doors to genetic diversity never before available for utilization by the sunflower industry. This led to his global stature with invitations to serve as a visiting scientist and fellowships in Australia, Serbia, Spain, Romania, and China. He has hosted over 20 scientists from 15 countries, as well as countless students during his career. Due to his stature, he has been invited to present several invited plenary talks, both national and international, and in 2012 he was presented the prestigious Pustovoit Award, the highest award in the sunflower industry given by the International Sunflower Association for his contribution to sunflower science and technology.

Published: May 2018

AbstractParticleboard (PB), medium density fibreboard (MDF), oriented strand board (OSB) and plywood (PW), the most common products of wood panel industry, are produced by means of synthetic adhesives (resins). From the wide range of adhesives employed, amino resins as combination of formaldehyde (F) and urea (U), and melamine (M) are the most important ones, which include the most popular UF and MUF resins. This review is an introduction to the UF and MUF synthesis processes, and also addresses the key parameters for the performance of these adhesives and gives an overview about the final characteristics of PB and MDF prepared with amino resins. The characterization methods for amino resins and panels are outlined. The strategies for the optimization of resin properties and pressing conditions are discussed in terms of their good performance also under conditions of low formaldehyde emission.

Authors: Nemestóthy Nándor 
Published: May 2018

Abstract
The long-term stability of membranes is determined mainly by their sensitivity to pollutants. Their stability was tested using a novel, multichannel measuring system, which is based on pressure differences. This measuring system is suitable to determine the changes in permeability of polymer membranes. The damaging effects of H2S, BTX and n-dodecane were investigated in terms of polyimide gas separation membranes using nitrogen gas.
Replacement of Biased Estimators with Unbiased Ones in the Case of Student’s t-Distribution and Geary’s Kurtosis
Authors: Tóth Gergely , Szepesváry Pál 
Published: May 2018

Abstract
The use of biased estimators can be found in some historically and up to now important tools in statistical data analysis. In this paper their replacement with unbiased estimators at least in the case of the estimator of the population standard deviation for normal distributions is proposed. By removing the incoherence from the Student’s t-distribution caused by the biased estimator, a corrected t-distribution may be defined. Although the quantitative results in most data analysis applications are identical for both the original and corrected tdistributions, the use of this last t-distribution is suggested because of its theoretical consistency. Moreover, the frequent qualitative discussion of the t-distribution has come under much criticism, because it concerns artefacts of the biased estimator. In the case of Geary’s kurtosis the same correction results (2/π)1/2 unbiased estimation of kurtosis for normally distributed data that is independent of the size of the sample. It is believed that by removing the sample-size-dependent biased feature, the applicability domain can be expanded to include small sample sizes for some normality tests.

Published: May 2018

Abstract
Heterogeneous photocatalysis can be successfully applied for the degradation of organic pollutants, although the efficiency of this method is insufficient. It can be increased by modification of the catalyst with precious metals (e.g. silver) or heterogeneous catalysis can be combined with other oxidative procedures such as ozonation. Another obstacle to the infield use of the method is that separating the catalyst from the liquid phase is difficult. This problem can be eliminated by the immobilization of the catalyst. The poly(vinyl alcohol)-TiO2 immobilized catalyst has been prepared for this purpose. During TiO2-based photocatalysis, active oxygen species such as the hydroxyl radical, superoxide radical and hydrogen peroxide are produced. The formation rate of the oxidative •OH radicals was also determined in the case of the previously mentioned techniques. As a scavenger of this radical, coumarin was added.
Surface Energy Heterogeneity Profiles of Carbon Nanotubes with a Copolymer-Modified Surface Using Surface Energy Mapping by Inverse Gas Chromatography
Authors: Gerencsér Fruzsina , Rieder Norbert , Varga Csilla , Hancsók Jenő , Dallos András 
Published: May 2018

Abstract
The effectiveness and quantitative control of the surface transition of multi-walled carbon nanotubes (MWCNTs) was characterized by inverse gas chromatography (iGC). The surface energy profile of carbon nanotubes compatibilized with an olefin-maleic-anhydride-ester-amide (OMAEA)-type coupling agent was determined by a surface energy analyzer (SEA). The surface energetic heterogeneity with energy distributions of dispersive and specific (acid-base) components of the surface energy of the MWCNTs were determined at various surface coverages. The results of the surface energy mapping showed that surface treatment significantly reduced the dispersive surface energy of MWCNTs and increased the specific surface energy. Furthermore, the surface modification enhanced its Lewis basic character and simultaneously decreased the acidic character of MWCNTs. It has been demonstrated that the surface treatment modified the heterogeneity profiles of the energetic surface of the carbonaceous nanomaterials.

Published: May 2018

Abstract
The equilibrium phases were investigated and the corresponding phase diagram constructed for the TlInP2Se6–In4(P2Se6)3 system from physical and chemical analyses, namely differential thermal analysis (DTA), X-ray diffraction (XRD), and microstructural analysis (MSA). It was established that this system belongs to the eutectic type and is characterized by the formation of boundary solid phases containing complex compounds. Single crystals of the compounds TlInP2Se6 and In4(P2Se6)3 were grown using the Bridgman method. Both crystals were found to exhibit diffuse reflection spectra and photoinduced dependence of birefringence at various IR wavelengths generated by CO2 laser irradiation. Birefringence properties were investigated using the Senarmont method.

Roberto Arlt: el Oriente “al margen del cable”
Authors: Camenen Gersende 
Published: May 2018

ResumenLa obra de Roberto Arlt da un giro inesperado a partir de 1935, año en que el escritor emprende un viaje por Marruecos que lo deslumbra. De aquí en adelante, el Oriente no cesará de aparecer en los textos de Arlt, con funciones tan distintas como sus contextos de publicación. Pese al entusiasmo del escritor, para la crítica posterior, Arlt será culpable de haber cedido a un orientalismo de pacotilla que empañaba, con sus aires conservadores, la poética vanguardista de sus grandes obras. Me propongo mostrar cómo en una serie de textos periodísticos publicados a finales de los años treinta, el escritor, liberado de sus aspiraciones a la legitimidad literaria, construye otra mirada sobre Oriente en un contexto internacional cambiado. En “Al margen del cable”, su columna en El Mundo a partir de 1937, Arlt recompone toda una trama de contactos internacionales (China-Alemania, Polinesia-Alemania-Estados-Unidos-Inglaterra) de modo que, si bien todavía actúan los filtros de los imaginarios orientalistas de la época, tanto populares (Hollywood) como cultos (Stevenson, Malraux), emerge en ellos una conciencia aguda de que el Oriente es parte de un mundo global que va formándose en la marcha hacia la guerra.
Poetas chilenos y sus dobles orientales: impostores y plagios
Authors: Faúndez Morán Pablo 
Published: May 2018

ResumenEl artículo rescata dos episodios de la vida literaria de las primeras décadas del siglo XX en Chile: la publicación del poemario Fragmentos del poeta afgano Karez-I-Roshan en 1921, y la acusación de plagio contra Pablo Neruda el año 1934. Ambos informan de una situación atractiva: dos veces y de formas distintas el poeta chileno se transfiguró en poeta oriental. La lectura propuesta permite apreciar a partir de ellos dos niveles en que el intercambio literario-cultural entre Chile y Oriente se vio obstaculizado por la mediación europea: primero, en la comprensión de un sistema de producción y difusión de las obras, y segundo, en la de la pertenencia de los escritores locales a una tradición occidental.
El Lejano Oriente en la poesía mexicana
Authors: Cross Elsa 
Published: May 2018

ResumenEl presente trabajo reúne los resultados de una investigación que explora la recepción que las culturas del Este de Asia, en todas sus manifestaciones, han tenido en poetas mexicanos a partir de 1900, fecha en que José Juan Tablada viajó al Japón. Más que una disquisición teórica, se ofrece una descripción de esta travesía que, si bien partió de un deslumbramiento estético, va a ir reflejando, posteriormente, el interés por ámbitos de la filosofía y la espiritualidad del Oriente, lo mismo que por diversas formas del arte culto y popular, así como por los paisajes, ciudades y costumbres. De los numerosos poetas que forman parte de dicha travesía, se hará hincapié en algunos autores paradigmáticos en los que puede apreciarse un cambio de rumbo o una aportación excepcional a través de la cual se harán evidentes los importantes cambios en el acercamiento hacia el fenómeno de lo “oriental” en la poesía mexicana.
Desplazamiento imaginario de Oriente: Augusto d’Halmar y la transmigración literaria del sujeto
Authors: Loebell Ricardo 
Published: May 2018

ResumenLa sombra del humo en el espejo, tríptico con Nirvana (1918) y Mi otro yo – De la doble vida en la India (1924), esboza una importante inflexión en la obra de Augusto d’Halmar, dado que con la experiencia del viaje concreto realizado a la India a finales de 1907 el autor enriquece el vaiven de la imaginación literaria de sus escritos. Atraído por lejanas culturas y diversas corrientes religiosas, d’Halmar compone allí narraciones donde el protagonista se desplaza desde América Latina al Extremo Oriente, en un viaje literario que no se realiza desde el Océano Pacífico sino por un camino indirecto, vía Europa, donde el autor hace un transbordo conceptual en el cual recoge ideas y sensaciones de la moda literaria europea del momento. En ese proceso se desembarca de conceptos nacionalistas, a la vez que rechaza el pensamiento hegemónico eurocéntrico y prefigura con ello conceptualizaciones y pensamientos centrales para la comprensión del Oriente y el fenómeno oriental desde lo americano.
La difusión global de la literatura filipina en español por una ruta transversal
Authors: Park Paula C. 
Published: May 2018

ResumenSi bien la literatura filipina en castellano ha sido prácticamente marginada en Filipinas y en el conjunto del mundo hispánico, el presente trabajo enfoca su difusión y recepción en Hispanoamérica en el siglo XX tomando en cuenta el hecho de que por 250 años (desde 1565 hasta 1815) Filipinas y el Virreinato de Nueva España desarrollaron una relación intercolonial, no sólo en términos comerciales sino también culturales. Entre los esfuerzos por difundir esta literatura se hallan la visita a México del escritor filipino Jesús Balmori en 1931, durante la cual organizó eventos culturales y recitó su poesía ante un público mexicano, y la labor del crítico y traductor húngaro-mexicano Pablo Laslo, quien publicó una edición bilingüe (castellano-alemán) más dos selecciones de poesía filipina en México y Argentina. A partir de estos dos casos, se explora el potencial crítico de la difusión de la literatura filipina en castellano en Hispanoamérica enfatizando las posibilidades y desafíos que surgen al estudiar la literatura filipina en castellano dentro del marco de las relaciones Sur-Sur.
Three accounts of propositional relation reports
Authors: Davis Wayne A. 
Published: May 2018

AbstractPeter Hanks and Scott Soames have developed a theory of propositions as structured cognitive event types, as have I in earlier works. They use the theory to offer similar accounts of transparent propositional relation reports, and very different accounts of opaque reports. For both, the sentences used to report propositional attitudes or speech acts are semantically unambiguous. Hanks invokes context-sensitivity, Soames pragmatics, to account for the different interpretations. I raise problems and offer solutions. Their accounts succumb to the non-compositionality of transparent reports, and wrongly predict that all propositional relation reports have both transparent and opaque interpretations. Soames’s pragmatic enrichment account of the opaque interpretation is unfounded, and forces him to conclude that competent speakers do not know what the sentences they use mean. The notion of an “object-dependent” or “bare” proposition is both problematic and unnecessary. I offer a new account, on which propositional relation reports have the semantic ambiguity characteristic of idioms, with the transparent interpretation being highly but not completely compositional.
A dialectical approach to presupposition
Authors: Macagno Fabrizio 
Published: May 2018

AbstractThis paper advances an approach to presupposition rooted in the concept of commitment, a dialectical notion weaker than truth and belief. It investigates ancient medieval dialectical theories and develops the insights thereof for analyzing how presuppositions are evaluated and why a proposition is presupposed. In particular, at a pragmatic level, presuppositions are reconstructed as the conclusions of implicit arguments from presumptive reasoning, grounded on presumptions of different type and nature. A false (or rather unaccepted) presupposition can be thus represented as the outcome of a conflict of presumptions – the ones used by the speaker and the ones commonly accepted or backed by evidence. From an interpretative perspective, this defaulted presumptive reasoning can be explained by comparing the available presumptions and repaired by replacing the weaker and unacceptable ones.
Areas of Civil Aviation Hazards

Published: May 2018

Abstract
Risk management is one of the most important tools of modern systemic approach to process modeling. Generally, it may be described as a system of interrelated actions and decisions aimed at integration and coordination of processes in the organization, in cooperation with the external parties. The aim of management is therefore to improve the proficiency, effectiveness and efficiency of the operation and - in the case of risk management arising from the transport processes - to improve flight safety. The publication describes a proposal of risk management method in air transport including analysis of areas threats to civil air operations.
