A Hybrid High-Order Method for Highly Oscillatory Elliptic Problems
Authors: Cicuttin Matteo , Ern Alexandre , Lemaire Simon 
Published: June 2018

Abstract
We devise a Hybrid High-Order (HHO) method for highly oscillatory elliptic problems that is capable of handling general meshes. The method hinges on discrete unknowns that are polynomials attached to the faces and cells of a coarse mesh; those attached to the cells can be eliminated locally using static condensation. The main building ingredient is a reconstruction operator, local to each coarse cell, that maps onto a fine-scale space spanned by oscillatory basis functions.
The present HHO method generalizes the ideas of some existing multiscale approaches, while providing the first complete analysis on general meshes. It also improves on those methods, taking advantage of the flexibility granted by the HHO framework. The method handles arbitrary orders of approximation

Was heißt es, Kunst als paradigmatische Praxis der zweiten Natur zu begreifen?
Authors: Bertram Georg W. 
Published: June 2018

AbstractThe paper argues that the concept of second nature has two aspects that are inherently bound up with one another. Firstly, second nature has to be conceived of as a concept that has a critical force. Secondly, art has to be understood as an essential part of what second nature is. The paper explains these two dimensions of the concept by drawing on Hegel’s and Heidegger’s conceptions of second nature as the nature of essentially incomplete beings. Since the incompleteness in question always has to be reproduced, human beings have to develop and constantly engage in practices of self-criticism. As a practice of self-criticism, art is constitutive of second nature understood in this way. Thus, the specificity of art is to be found in its form of self-criticism as articulated through objects, which for their part give orientation to beings that realize their second nature through their practices. In the end, art prompts them to revise and enliven these practices.
Cubic Transmuted-G Family of Distributions and Its Properties
Authors: Aslam Muhammad , Hussain Zawar , Asghar Zahid 
Published: June 2018

Abstract
In this article, a new family of distributions is introduced by using transmutation maps. The proposed family of distributions is expected to be useful in modeling real data sets. The genesis of the proposed family, including several statistical and reliability properties, is presented. Methods of estimation like maximum likelihood, least squares, weighted least squares, and maximum product spacing are discussed. Maximum likelihood estimation under censoring schemes is also considered. Further, we explore some special models of the proposed family of distributions and examined different properties of these special models. We compare three particular models of the proposed family with several existing distributions using different information criteria. It is observed that the proposed particular models perform better than different competing models. Applications of the particular models of the proposed family of distributions are finally presented to establish the applicability in real life situations.
Nitrogen Adsorption Compounds in the Presence of Dibenzothiophene on Mesoporous Materials for Obtaining Ultra-Low-Sulfur Diesel

Published: June 2018

AbstractThis work presents the adsorption process of nitrogen compounds, namely quinoline (Q), pyridine (Pyr), and indole (In), from liquid fuels such as gasoline and diesel containing dibenzothiophene (DBT) as sulfur-containing molecules. These compounds were adsorbed on mesoporous materials, namely SBA-15 and SBA-16, in calcined form in batch mode using dodecane as a solvent represent to a diesel mixture. The main conclusion of this research is that SBA-15 showed a higher nitrogen adsorption capacity than SBA-16 for all molecules containing nitrogen and sulfur. A comparative study of nitrogen and sulfur adsorption confirms that selective removal of nitrogen compounds from fuels using SBA-15 was better than that of sulfur compounds. Moreover, an increase in the adsorption of Q was found with SBA-15 material compared to SBA-16. To explain this behavior, the solids were characterized using X-ray diffraction (XRD), nitrogen physisorption, and High-Resolution Transmission Electron Microscopy (HRTEM). A pseudo-second-order kinetic model, rather than a first-order one, fitted the nitrogen adsorption data best. Moreover, the Langmuir model was suitable for describing the adsorption of nitrogen compounds from simulated diesel fuel, instead of the Freundlich model, which means that nitrogen compounds are adsorbed in a monolayer.
Protection Systems and Earthing Schemes for Microgrids: Main Aspects and Fault Analysis
Authors: Bandeiras Filipe , Gomes Mário , Coelho Paulo , Fernandes José , Moreira Carlos 
Published: June 2018

AbstractThe content of this paper aims to assist in the development and implementation of microgrids by addressing the challenges and possible solutions for their protection systems. Therefore, an overview of some protection methods available in the literature that can be implemented to ensure a safe and reliable microgrid operation is presented, including the most common protection devices and earthing schemes that can be adopted in low voltage distribution systems. In addition, this paper also presents a brief fault analysis of internal faults at three different locations in an industrial microgrid with centralized and decentralized deployment of energy sources, as well as a short-circuit analysis of symmetric and asymmetric faults at these faulty locations. An approximate method based on the calculation of the equivalent impedance seen from the fault location is used to determine the fault currents. This study is made to observe how microgrids with different configurations perform in the event of internal faults.It is demonstrated in this work that setting a specific protection strategy to allow the microgrid to operate effectively during both operation modes can be problematic and expensive in most situations. With this in mind, additional effort is necessary to engineer and implement new protection approaches that can overcome the limitations of protection systems in future microgrids.
Ius vitae necisque: the politics of killing children
Authors: Curran John 
Published: June 2018

AbstractThis paper seeks to challenge the long-standing interpretation of the ius vitae necisque as a formal legal right of Roman fathers. It offers a review and critique of the evidence upon which the claim of ancient origin is founded and highlights the consequent problems in comprehending late Republican and Imperial references to the killing of sons by fathers. An alternative and more satisfactory understanding is to be found in sociological thinking and it is argued that the comprehension of the ius vitae necisque as a formal right is not only invalid but obscures the real significance of its promotion as a political phenomenon in the age of Augustus and the early emperors of Rome.
Camillus as Numa: religion in Livy’s refoundation narratives
Authors: McIntyre Gwynaeth 
Published: June 2018

AbstractLivy’s first pentad of Ab Urbe Condita begins and ends with the founding and refounding of the city. Both are achieved first through violence and then through the establishment and re-establishment of religious authority and the restoration of Rome’s relationship with its gods. This article examines the connection Livy makes between Numa and Camillus and the place of religion within the refoundation narratives. The religious topography of Rome is essential to Camillus’ argument for the Romans to remain in the city following the Gallic sack. By citing particular priesthoods, the flamen Dialis and the Vestal Virgins in particular, both of which were established or developed by Numa, Livy not only constructs Camillus as a new Numa but also promotes these priesthoods as monumenta. Camillus’ speech forges direct connections between Rome’s conditores, the topography of the city, the devotion to its gods, and the city’s continued glory.
Anzahl und Ausmaß. Die griechisch-arabisch-lateinische Rezeption der aristotelischen Zeitdefinition
Authors: Lammer Andreas 
Published: June 2018

AbstractThis paper traces the reception of the Aristotelian definition of time from its earliest (Boethus of Sidon) to its most authoritative interpretations (Alexander of Aphrodisias), and describes how their readings pave the way for a sophisticated amalgamation of divergent Aristotelian and Platonic elements in the temporal theory of Avicenna. The focus of attention lies on specific perceptions of the relation between time and motion, more precisely on the contrary descriptions of time as the measure of motion and motion as the measure of time. The latter leads to a conception of time as a universal self-subsisting substance beyond all measure, and the former to an understanding of time as an accident providing all motion with its particular measure. It is the antagonism between these two conceptions, both inherent in the Arabic term miqdār (“measure, magnitude”) at the heart of Avicenna’s definition of time, which arguably informs the Latin tradition and thereby also shapes the early modern contrast between objective and subjective theories of time.
Angemessene Tugend und Wissenserwerb in der byzantinischen Ethik des Michael Psellos
Authors: Walter Denis 
Published: June 2018

AbstractThe Byzantine philosopher Michael Psellos (1018–1078 AD) describes in his ethics two kinds of virtue: practical and intellectual virtues. Practical virtues are defined as a middle term between two extremes as is known from the Aristotelian tradition. His innovation is to define also a middle regarding the intellectual virtues. He says that the highest object of knowledge is not graspable for the human intellect because it exceeds his powers. Whoever strives to understand the highest object of knowledge, the essence of god, is determined to fail. Thus, the best objects that the human intellect can contemplate are situated below god, in the “middle”. The concept of the middle is thus present twice in Psellos’ ethics: once in the practical virtues and once in the intellectual virtues.
Das Maßlose Begreifen. Gott als Gegenstand der Theologie bei vier scholastischen Autoren (13./14. Jahrhundert)
Authors: Wöller Florian 
Published: June 2018

AbstractThis article examines four medieval views on the subject of theology. Thomas Aquinas, Giles of Rome, John Duns Scotus, and Peter Auriol were all confronted with an idea based on Aristotle’s theory of knowledge according to which any scientific discipline is unified by its proper subject. In defining this subject of theology, however, the theologians had to confront one thorny problem: God, whom they considered to be the subject of theology, cannot be grasped by any concept accessible to the human mind. In their respective discussions, two distinct strategies to solving this puzzle emerged. Aquinas and Giles, on the one hand, argued for a concept proportionate to human cognition. This concept or ratio functioned as a placeholder for the quidditative concept of God. Scotus and Auriol, on the other hand, elaborated on a concept which they believed grasped God’s quiddity, albeit in a somewhat approximative way. Their theories, therefore, figure as attempts to find a concept, that is, the concept of being, that in itself was as boundless as to grasp God’s immensity.
Size-fractionated chlorophyll a and phycocyanin temporal variations in a highly eutrophic lake and its isolated karstic springs

Published: June 2018

Abstract
Monthly variations of size-fractionated chlorophyll a and phycocyanin were studied in Lake Pamvotis between August 2016 and January 2017. Sampling was conducted at two sampling sites: in the main lake (Site 1: Lake) and in an adjacent man-made water ski lake with karstic springs (Site 2: Springs). Samples were fractionated into three size classes: 0.2–2 μm (pico), 2–20 μm (nano) and 20–180 μm (micro). According to chlorophyll a values, eutrophic to hypereutrophic conditions prevail at Site 1 and oligotrophic to mesotrophic conditions – at Site 2. Similarly, Site 1 was distinguished by higher concentration of phycocyanin compared to Site 2. Fractionated chlorophyll a showed monthly variations at Site 1 with alternations in the dominance between the two larger fractions. The maximum of the 0.2–2 μm fraction was observed in October but it contributed less to the total chlorophyll a content than nano- or microphytoplankton. Its contribution was higher at Site 2, reaching occasionally ~ 40% of the bulk chlorophyll a. However, nanophytoplankton was the fraction found to respond faster when disturbances occurred. At Site 1, phycocyanin correlated well with total chlorophyll a as well as with the micro- and nanophytoplankton fractions, indicating that cyanobacteria represent an important component of the large-sized phytoplankton in Lake Pamvotis.

Published: June 2018

Abstract
The aim of the study was to indicate the abiotic parameters of water and bottom sediments, which significantly affect the reproduction of Potamothrix hammoniensis in 9 shallow eutrophic lakes, of which 5 were dominated by macrophytes and 4 – by phytoplankton. Samples were collected once a month from January to December 2012.
The percentage of Potamothrix hammoniensis individuals with a developed reproductive system varied in individual lakes and ranged from 14 to 72%. There was no correlation between the distinguished lake types and the proportion of sexually mature individuals. The reproductive activity was not observed in summer and early autumn. Among the measured parameters, the highest values of the Pearson correlation coefficient were found between the percentage of individuals with a developed reproductive system and the conductivity (r = 0.69; p < 0.001), pH (r = 0.51; p = 0.002) and the organic matter content in the sediments (r = −0.42; p = 0.012). It is worth noting that there was no correlation between the percentage of sexually mature specimens and the water temperature (r = −0.22, p = 0.204) and the oxygen concentration (r = −0.08; p = 0.648).
Applying industrial tomography to control and optimization flow systems
Authors: Rymarczyk Tomasz , Sikora Jan 
Published: June 2018

Abstract
The flow control and optimization system based on industrial tomography is presented in this publication. Multiphase flow measurement technologies are still being built and improved. There is a clear tendency in the industry to implement more optimally related functions with an emphasis on active inspection and monitoring. Control methods include issues related to the processing of data obtained from various sensors located in nodes. Monitoring takes place within the scope of acquired and processed data and parameter automation. The main purpose of this work is to design a system for data acquisition and analysis by image reconstruction for various tomographic methods (resistive, capacitive, ultrasonic). The practical application of ultrasonic flow measurement to study gas emissions in the heat and power station chimney is presented
Using Exponentially Weighted Moving Average to Improve Buffer Adjustment of Demand-Driven Replenishment Strategies
Authors: Chang Yung-Chia , Chang Kuei-Hu , Lee Mu-Chien , Tsao Kuo-Hao 
Published: June 2018

Abstract
Stock management is a critical issue in supply chain management. Previous studies have shown that the demand-pull inventory replenishment strategy combined with a buffer management mechanism (DPBM) suggested by the theory of constraints (TOC) performs better than traditional replenishment strategies in supply chain stock management. In DPBM, buffer management is applied for controlling the target amount of stock to keep, which is adjusted by some predetermined rules that instruct when and how much to adjust the target level. Previous studies found that when applying DPBM to making replenishment decisions for products with a high-variation demand, long production lead-time, and short product life cycle, the conventional DPBM is not very effective. This article proposes a novel method for improving the conventional buffer management mechanism. Instead of the predetermined rules suggested by TOC, this study borrowed the concept of the exponentially weighted moving average approach that has been successfully applied in statistical quality control to design a new set of rules to assist in making buffer adjustment decisions based on the trends shown in demand. To evaluate the proposed method’s feasibility and validity, this article uses both real demand data provided by a wafer foundry factory in Taiwan and simulated data that reveal various demand patterns. As a result, the proposed method performs better than the conventional demand-driven replenishment strategies suggested by TOC, especially when demand has a large variance.
Réflexion sur la pertinence de s’intéresser aux stratégies d’étude des étudiants ayant un trouble d’apprentissage ou un TDA/H afin de favoriser leur réussite scolaire
Authors: Turcotte Jonathan , Doucet Manon , Baron Marie-Pierre 
Published: June 2018

Depuis les deux dernières décennies, le nombre d’étudiants collégiaux ayant un trouble d’apprentissage (TA) ou un trouble du déficit de l’attention avec ou sans hyperactivité (TDA/H) a connu une augmentation fulgurante et il apparait de plus en plus urgent de se préoccuper davantage de leur réussite scolaire. L’un des principaux obstacles à la réussite identifiés par ces étudiants est « le manque de technique pour étudier » (Wolforth et Roberts, 2010, p. 28). Cet article cherche à démontrer la nécessité de s’intéresser de près aux stratégies d’études employées par les étudiants collégiaux qui ont un TA ou TDA/H afin de s’assurer que ces derniers utilisent des stratégies d’études efficaces.
Reading Books Differently
Authors: Bădulescu Dana , Cristea Dan 
Published: June 2018

[full article, abstract in English; abstract in Lithuanian]
Starting from the premise that the book is a world in itself, which sometimes invades reality, that the “reality” of the city is “literaturized” in the sense given to it by Bertrand Westphal, and so the city is a book, we present a technology intended to complement electronic reading with contextual information. Automatic language processes working on the original text adorn it with electronic artefacts that highlight mentions of entities and relations between them, thus revealing semantic links within the text and outside it, towards web pages and maps, or helping readers initiate and access communities of people preoccupied with sharing readings. The first instantiation of the “Mapping Books” system allows the reader using a tablet or another mobile device to navigate outside the book, pertaining to the geographical entities that the book contains. “Mapping Books” pushes the interactivity with the book content well beyond the usual hypertext links: a mapped book can contextualise instantaneous positions of the user while reading, as well as her/his personality and cultural preferences. Although rooted in a given, constant text, once associated with a specific reader, the book is personalised to enhance reading satisfaction and maximise guiding. The actual effects of such a technology remain to be studied.
RESECTION OF ULNAR NERVE GIANT CELL NEURINOMA
Authors: Mahadewa Tjokorda Gde Bagus 
Published: June 2018

Giant cellular ulnar nerve neurinoma is a very rare condition. According to the literature, the author reports the first case while only two other reports of the cellular neurinoma can be found in English literature in different locations. The author presents the case of large size cellular neurinoma of the ulnar nerve, where the primary tumour was resected using the shelled out technique, without neurolysis and any nerve repair. Histopathologic characteristics, radiological findings and clinical data on these tumours were reviewed, and the proposed chosen surgical technique, which differs from that used in the previous cases and taking into account the rate of recurrence after total resection.

Authors: Janotti Leticia , Mendes Junior Walter Vieira 
Published: June 2018

Justificativa e Objetivo: Apesar da presença de indicadores obrigatórios nos protocolos de higiene das mãos, presentes no Programa Nacional de Segurança do Paciente do Brasil, não foram recomendados instrumentos de monitoramento, com indicadores que avaliem os componentes estruturais, de processo e resultado que permitam análise periódica e construção de ações de melhoria no âmbito da prevenção de controle das infecções relacionadas à assistência à saúde. O objetivo foi adequar um instrumento de monitoramento da higienização das mãos dos profissionais de saúde de um hospital do Rio de Janeiro. Métodos: um questionário foi aplicado aos auditores que avaliam o desempenho da política de qualidade do hospital para verificar a adequação de um instrumento de verificação da prática de higienização das mãos. Os achados deste questionário e os dados do levantamento na literatura - sobre a segurança do paciente, infecções relacionadas à assistência à saúde e instrumentos de monitoramento - possibilitaram a criação de um novo instrumento, que foi
submetido ao julgamento de especialistas, usando a técnica de consenso Delphi. Resultados: em duas rodadas foi obtido um consenso dos especialistas. As questões que não atingiram 75% de concordância foram modificadas. Conclusão: O novo instrumento validado por especialistas permite a avaliação e monitoramento de implantação do protocolo de
higienização das mãos, comparação entre sistemas e avanços nas metodologias e processos de trabalho, permitindo que sejam cada vez mais seguros.
