The Lebanese Electricity Woes: An Estimation of the Economical Costs of Power Interruptions
Authors: Bouri Elie , El Assad Joseph
Published: July 2016

This paper contributes to the political and scientific debate surrounding the economic costs entailed by the regular power cuts in Lebanon. Examining the data on electricity consumption that was produced by onshore and offshore power plants, this paper estimates the economical costs of power interruptions in Lebanon over the period 2009–2014. Based on 700 USD/MWh, representing the average value of lost load (VOLL) in that period, results indicate that electricity shortages continue to render significant transfers of wealth to the detriment of economy and society as a whole. Over the period 2009–2014, the total losses for the Lebanese economy reached 23.23 billion USD. Just as importantly, some evidence suggests a sharp decline in the economical costs of power interruptions with the inception of the two floating power plants in 2013. The results are crucial for the decision makers to identify the economic efficiency of alternative measures to enhance the security of the Lebanese electricity supply.

Published: July 2016

Passive cooling techniques have been used mostly in countries with hot and arid climates such as Iran, Egypt, and India. However, the use of this important technology has not been seriously considered until a time of energy crisis, and consequently, environmental crisis scenarios, emerge. Scholars have renewed their interest in investigating passive cooling technology, particularly the aspects of new materials, thermal comfort, energy efficiency, new designs, climate, and environmental considerations. This review paper highlights the opportunities to use green materials, such as geopolymers, as evaporative cooling materials with different types of industrial and agricultural waste products as components. Novel ideas for passive cooling design using ancient and nature-inspired concepts are also presented to promote green technology for future applications.
Dynamic Prediction of Power Storage and Delivery by Data-Based Fractional Differential Models of a Lithium Iron Phosphate Battery
Authors: Jiang Yunfeng , Zhao Xin , Valibeygi Amir , De Callafon Raymond
Published: July 2016

A fractional derivative system identification approach for modeling battery dynamics is presented in this paper, where fractional derivatives are applied to approximate non-linear dynamic behavior of a battery system. The least squares-based state-variable filter (LSSVF) method commonly used in the identification of continuous-time models is extended to allow the estimation of fractional derivative coefficents and parameters of the battery models by monitoring a charge/discharge demand signal and a power storage/delivery signal. In particular, the model is combined by individual fractional differential models (FDMs), where the parameters can be estimated by a least-squares algorithm. Based on experimental data, it is illustrated how the fractional derivative model can be utilized to predict the dynamics of the energy storage and delivery of a lithium iron phosphate battery (LiFePO 4 ) in real-time. The results indicate that a FDM can accurately capture the dynamics of the energy storage and delivery of the battery over a large operating range of the battery. It is also shown that the fractional derivative model exhibits improvements on prediction performance compared to standard integer derivative model, which in beneficial for a battery management system.
One-Carbon Metabolism in Prostate Cancer: The Role of Androgen Signaling
Authors: Corbin Joshua , Ruiz-Echevarría Maria
Published: July 2016

Cancer cell metabolism differs significantly from the metabolism of non-transformed cells. This altered metabolic reprogramming mediates changes in the uptake and use of nutrients that permit high rates of proliferation, growth, and survival. The androgen receptor (AR) plays an essential role in the establishment and progression of prostate cancer (PCa), and in the metabolic adaptation that takes place during this progression. In its role as a transcription factor, the AR directly affects the expression of several effectors and regulators of essential catabolic and biosynthetic pathways. Indirectly, as a modulator of the one-carbon metabolism, the AR can affect epigenetic processes, DNA metabolism, and redox balance, all of which are important factors in tumorigenesis. In this review, we focus on the role of AR-signaling on one-carbon metabolism in tumorigenesis. Clinical implications of one-carbon metabolism and AR-targeted therapies for PCa are discussed in this context.

Published: July 2016

The accurate diagnosis and management of individuals with interstitial lung diseases (ILDs) poses an interesting challenge in clinical practice. A multidisciplinary team (MDT) approach is considered the gold standard. This is a single-centre retrospective review spanning a five-year period. We assessed the accuracy of prior ILD diagnosis, the methodology used to establish a correct diagnosis and how an MDT approach affected subsequent management. Our data supports an MDT approach in an experienced specialist ILD centre. We have demonstrated that diagnosis is often changed after an MDT review and that this impacts the subsequent management. Our results demonstrate that an MDT approach to diagnosis can establish a diagnosis in the majority of cases when prior diagnosis is uncertain (76%). We also show that a prior diagnosis of idiopathic pulmonary fibrosis is deemed inaccurate in over 50% of cases after MDT discussion. We have shown that during diagnostic uncertainty the considered gold standard of proceeding to a lung biopsy is not always feasible due to disease severity and comorbidities. In these circumstances, an MDT approach to diagnosis of ILDs combines clinical data with serial lung function and disease behavior, with or without responses to previous treatment trials to establish an accurate expert diagnosis.
A Novel Fabrication Technique for Liquid-Tight Microchannels by Combination of a Paraffin Polymer and a Photo-Curable Silicone Elastomer
Authors: Mogi Katsuo , Sakata Kenshiro , Hashimoto Yuki , Yamamoto Takatoki
Published: July 2016

The development and growth of microfluidics has been mainly based on various novel fabrication techniques for downsizing and integration of the micro/nano components. Especially, an effective fabrication technique of three-dimensional structures still continues to be strongly required in order to improve device performance, functionality, and device packing density because the conventional lamination-based technique for integrating several two-dimensional components is not enough to satisfy the requirement. Although three-dimensional printers have a high potential for becoming an effective tool to fabricate a three-dimensional microstructure, a leak caused by the roughness of a low-precision structure made by a 3D printer is a critical problem when the microfluidic device is composed of several parts. To build a liquid-tight microchannel on such a low-precision structure, we developed a novel assembly technique in which a paraffin polymer was used as a mold for a microchannel of photo-curable silicone elastomer on a rough surface. The shape and roughness of the molded microchannel was in good agreement with the master pattern. Additionally, the seal performance of the microchannel was demonstrated by an experiment of electrophoresis in the microchannel built on a substrate which has a huge roughness and a joint.
Negative Thermal Expansion in Ba0.5Sr0.5Zn2SiGeO7
Authors: Thieme Christian , Rüssel Christian
Published: July 2016

Solid solutions with the composition Ba0.5Sr0.5Zn2Si2-xGexO7 and BaZn2Si2-xGexO7 were prepared with different values of x using a conventional mixed oxide route. Both compounds exhibit very different thermal expansion, which is due to the different crystal structures. Ba0.5Sr0.5Zn2Si2-xGexO7 solid solutions exhibit the structure of high-temperature BaZn2Si2O7 and show negative thermal expansion, which was proven via high-temperature X-ray diffraction. Up to around x = 1, the crystal structure remains the same. Above this value, the low-temperature phase becomes stable. The Sr-free solid solutions have the crystal structure of low-temperature BaZn2Si2O7 and show also a limited solubility of Ge. These Sr-free compositions show transitions of low- to high-temperature phases, which are shifted to higher temperatures with increasing Ge-concentration.

Published: July 2016

In this paper, a novel velocimeter based on laser self-mixing Doppler technology has been developed for speed measurement. The laser employed in our experiment is a distributed feedback (DFB) fiber laser, which is an all-fiber structure using only one Fiber Bragg Grating to realize optical feedback and wavelength selection. Self-mixing interference for optical velocity sensing is experimentally investigated in this novel system, and the experimental results show that the Doppler frequency is linearly proportional to the velocity of a moving target, which agrees with the theoretical analysis commendably. In our experimental system, the velocity measurement can be achieved in the range of 3.58 mm/s–2216 mm/s with a relative error under one percent, demonstrating that our novel all-fiber configuration velocimeter can implement wide-range velocity measurements with high accuracy.
SUPRATHERMAL ELECTRONS IN TITAN’S SUNLIT IONOSPHERE: MODEL–OBSERVATION COMPARISONS

Published: July 2016

The dayside ionosphere of the Saturnian satellite Titan is generated mainly from photoionization of N2 and CH4. We compare model-derived suprathermal electron intensities with spectra measured by the Cassini Plasma Spectrometer/Electron Spectrometer (CAPS/ELS) in Titan's sunlit ionosphere (altitudes of 970–1250 km) focusing on the T40, T41, T42, and T48 Titan flybys by the Cassini spacecraft. The model accounts only for photoelectrons and associated secondary electrons, with a main input being the impinging solar EUV spectra as measured by the Thermosphere Ionosphere Mesosphere Energy and Dynamics/Solar EUV Experiment and extrapolated to Saturn. Associated electron-impact electron production rates have been derived from ambient number densities of N2 and CH4 (measured by the Ion Neutral Mass Spectrometer/Closed Source Neutral mode) and related energy-dependent electron-impact ionization cross sections. When integrating up to electron energies of 60 eV, covering the bulk of the photoelectrons, the model-based values exceed the observationally based values typically by factors of ∼3 ± 1. This finding is possibly related to current difficulties in accurately reproducing the observed electron number densities in Titan's dayside ionosphere. We compare the utilized dayside CAPS/ELS spectra with ones measured in Titan's nightside ionosphere during the T55–T59 flybys. The investigated nightside locations were associated with higher fluxes of high-energy (>100 eV) electrons than the dayside locations. As expected, for similar neutral number densities, electrons with energies <60 eV give a higher relative contribution to the total electron-impact ionization rates on the dayside (due to the contribution from photoelectrons) than on the nightside.
MULTI-SPACECRAFT OBSERVATIONS AND TRANSPORT MODELING OF ENERGETIC ELECTRONS FOR A SERIES OF SOLAR PARTICLE EVENTS IN AUGUST 2010
Authors: Dröge W. , Kartavykh Y. Y. , Dresing N. , Klassen A.
Published: July 2016

During 2010 August a series of solar particle events was observed by the two STEREO spacecraft as well as near-Earth spacecraft. The events, occurring on August 7, 14, and 18, originated from active regions 11093 and 11099. We combine in situ and remote-sensing observations with predictions from our model of three-dimensional anisotropic particle propagation in order to investigate the physical processes that caused the large angular spreads of energetic electrons during these events. In particular, we address the effects of the lateral transport of the electrons in the solar corona that is due to diffusion perpendicular to the average magnetic field in the interplanetary medium. We also study the influence of two coronal mass ejections and associated shock waves on the electron propagation, and a possible time variation of the transport conditions during the above period. For the August 18 event we also utilize electron observations from the MESSENGER spacecraft at a distance of 0.31 au from the Sun for an attempt to separate between radial and longitudinal dependencies in the transport process. Our modelings show that the parallel and perpendicular diffusion mean free paths of electrons can vary significantly not only as a function of the radial distance, but also of the heliospheric longitude. Normalized to a distance of 1 au, we derive values of λ
∥ in the range of 0.15–0.6 au, and values of λ
⊥ in the range of 0.005–0.01 au. We discuss how our results relate to various theoretical models for perpendicular diffusion, and whether there might be a functional relationship between the perpendicular and the parallel mean free path.
DOUBLE DYNAMO SIGNATURES IN A GLOBAL MHD SIMULATION AND MEAN-FIELD DYNAMOS
Authors: Beaudoin Patrice , Simard Corinne , Cossette Jean-François , Charbonneau Paul
Published: July 2016

The 11 year solar activity cycle is the most prominent periodic manifestation of the magnetohydrodynamical (MHD) large-scale dynamo operating in the solar interior, yet longer and shorter (quasi-) periodicities are also present. The so-called “quasi-biennial” signal appearing in many proxies of solar activity has been gaining increasing attention since its detection in p-mode frequency shifts, which suggests a subphotospheric origin. A number of candidate mechanisms have been proposed, including beating between co-existing global dynamo modes, dual dynamos operating in spatially separated regions of the solar interior, and Rossby waves driving short-period oscillations in the large-scale solar magnetic field produced by the 11 year activity cycle. In this article, we analyze a global MHD simulation of solar convection producing regular large-scale magnetic cycles, and detect and characterize shorter periodicities developing therein. By constructing kinematic mean-field α
2Ω dynamo models incorporating the turbulent electromotive force (emf) extracted from that same simulation, we find that dual-dynamo behavior materializes in fairly wide regions of the model’s parameters space. This suggests that the origin of the similar behavior detected in the MHD simulation lies with the joint complexity of the turbulent emf and differential rotation profile, rather that with dynamical interactions such as those mediated by Rossby waves. Analysis of the simulation also reveals that the dual dynamo operating therein leaves a double-period signature in the temperature field, consistent with a dual-period helioseismic signature. Order-of-magnitude estimates for the magnitude of the expected frequency shifts are commensurate with helioseismic measurements. Taken together, our results support the hypothesis that the solar quasi-biennial oscillations are associated with a secondary dynamo process operating in the outer reaches of the solar convection zone.
THE NUCLEUS OF THE PLANETARY NEBULA EGB 6 AS A POST-MIRA BINARY*
Authors: Bond Howard E. , Ciardullo Robin , Esplin Taran L. , Hawley Steven A. , Liebert James , Munari Ulisse
Published: July 2016

EGB 6 is a faint, large, ancient planetary nebula (PN). Its central star, a hot DAOZ white dwarf (WD), is a prototype of a rare class of PN nuclei associated with dense, compact emission-line knots. The central star also shows excess fluxes in both the near-infrared (NIR) and mid-infrared (MIR). In a 2013 paper, we used Hubble Space Telescope (HST) images to show that the compact nebula is a point-like source, located 0.″16 (∼118 AU) from the WD. We attributed the NIR excess to an M dwarf companion star, which appeared to coincide with the dense emission knot. We now present new ground-based NIR spectroscopy, showing that the companion is actually a much cooler source with a continuous spectrum, apparently a dust-enshrouded low-luminosity star. New HST images confirm common proper motion of the emission knot and red source with the WD. The I-band, NIR, and MIR fluxes are variable, possibly on timescales as short as days. We can fit the spectral energy distribution (SED) with four blackbodies (the WD, a ∼1850 K NIR component, and MIR dust at 385 and 175 K). Alternatively, we show that the NIR/MIR SED is very similar to that of Class 0/I young stellar objects. We suggest a scenario in which the EGB 6 nucleus is descended from a wide binary similar to the Mira system, in which a portion of the wind from an AGB star was captured into an accretion disk around a companion star; a remnant of this disk has survived to the present time and is surrounded by gas photoionized by UV radiation from the WD.
SUPERNOVA DRIVING. III. SYNTHETIC MOLECULAR CLOUD OBSERVATIONS

Published: July 2016

We present a comparison of molecular clouds (MCs) from a simulation of supernova (SN) driven interstellar medium (ISM) turbulence with real MCs from the Outer Galaxy Survey. The radiative transfer calculations to compute synthetic CO spectra are carried out assuming that the CO relative abundance depends only on gas density, according to four different models. Synthetic MCs are selected above a threshold brightness temperature value, T
B,min = 1.4 K, of the J = 1 − 0 12CO line, generating 16 synthetic catalogs (four different spatial resolutions and four CO abundance models), each containing up to several thousands MCs. The comparison with the observations focuses on the mass and size distributions and on the velocity–size and mass–size Larson relations. The mass and size distributions are found to be consistent with the observations, with no significant variations with spatial resolution or chemical model, except in the case of the unrealistic model with constant CO abundance. The velocity–size relation is slightly too steep for some of the models, while the mass–size relation is a bit too shallow for all models only at a spatial resolution dx ≈ 1 pc. The normalizations of the Larson relations show a clear dependence on spatial resolution, for both the synthetic and the real MCs. The comparison of the velocity–size normalization suggests that the SN rate in the Perseus arm is approximately 70% or less of the rate adopted in the simulation. Overall, the realistic properties of the synthetic clouds confirm that SN-driven turbulence can explain the origin and dynamics of MCs.
THE BLACK HOLE CENTRAL ENGINE FOR ULTRA-LONG GAMMA-RAY BURST 111209A AND ITS ASSOCIATED SUPERNOVA 2011KL
Authors: Gao He , Lei Wei-Hua , You Zhi-Qiang , Xie Wei
Published: July 2016

Recently, the first association between an ultra-long gamma-ray burst (GRB) and a supernova was reported, i.e., GRB 111209A/SN 2011kl, enabling us to investigate the physics of central engines or even progenitors for ultra-long GRBs. In this paper, we inspect the broadband data of GRB 111209A/SN 2011kl. The late-time X-ray light curve exhibits a GRB 121027A-like fallback bump, suggesting a black hole (BH) central engine. We thus propose a collapsar model with fallback accretion for GRB 111209A/SN 2011kl. The required model parameters, such as the total mass and radius of the progenitor star, suggest that the progenitor of GRB 111209A is more likely a Wolf–Rayet star instead of a blue supergiant, and the central engine of this ultra-long burst is a BH. The implications of our results are discussed.
GAS LOSS BY RAM PRESSURE STRIPPING AND INTERNAL FEEDBACK FROM LOW-MASS MILKY WAY SATELLITES
Authors: Emerick Andrew , Low Mordecai-Mark Mac , Grcevich Jana , Gatto Andrea
Published: July 2016

The evolution of dwarf satellites in the Milky Way (MW) is affected by a combination of ram pressure stripping (RPS), tidal stripping, and internal feedback from massive stars. We investigate gas loss processes in the smallest satellites of the MW using three-dimensional, high-resolution, idealized wind tunnel simulations, accounting for gas loss through both ram pressure stripping and expulsion by supernova feedback. Using initial conditions appropriate for a dwarf galaxy like Leo T, we investigate whether or not environmental gas stripping and internal feedback can quench these low-mass galaxies on the expected timescales, shorter than 2 Gyr. We find that supernova feedback contributes negligibly to the stripping rate for these low star formation rate galaxies. However, we also find that RPS is less efficient than expected in the stripping scenarios we consider. Our work suggests that although RPS can eventually completely strip these galaxies, other physics is likely at play to reconcile our computed stripping times with the rapid quenching timescales deduced from observations of low-mass MW dwarf galaxies. We discuss the roles additional physics may play in this scenario, including host-satellite tidal interactions, cored versus cuspy dark matter profiles, reionization, and satellite preprocessing. We conclude that a proper accounting of these physics together is necessary to understand the quenching of low-mass MW satellites.
ON THE OPTICAL–X-RAY CORRELATION FROM OUTBURST TO QUIESCENCE IN LOW-MASS X-RAY BINARIES: THE REPRESENTATIVE CASES OF V404 CYG AND CEN X-4

Published: July 2016

Low-mass X-ray binaries (LMXBs) show evidence of a global correlation of debated origin between X-ray and optical luminosity. We study for the first time this correlation in two transient LMXBs, the black hole (BH) V404 Cyg and the neutron star Cen X-4, over six orders of magnitude in X-ray luminosity, from outburst to quiescence. After subtracting the contribution from the companion star, the Cen X-4 data can be described by a single power-law correlation of the form

, consistent with disk reprocessing. We find a similar correlation slope for V404 Cyg in quiescence (0.46) and a steeper one (0.56) in the outburst hard state of 1989. However, V404 Cyg is about 160–280 times optically brighter, at a given 3–9 keV X-ray luminosity, compared to Cen X-4. This ratio is a factor of 10 smaller in quiescence, where the normalization of the V404 Cyg correlation also changes. Once the bolometric X-ray emission is considered and the known main differences between V404 Cyg and Cen X-4 are taken into account (a larger compact object mass, accretion disk size, and the presence of a strong jet contribution in the hard state for the BH system), the two systems lie on the same correlation. In V404 Cyg, the jet dominates spectrally at optical–infrared frequencies during the hard state but makes a negligible contribution in quiescence, which may account for the change in its correlation slope and normalization. These results provide a benchmark to compare with data from the 2015 outburst of V404 Cyg and, potentially, other transient LMXBs as well.
FERROMAGNETISM AND PARTICLE COLLISIONS: APPLICATIONS TO PROTOPLANETARY DISKS AND THE METEORITICAL RECORD
Authors: Hubbard Alexander
Published: July 2016

The meteoritical record shows both iron partitioning and tungsten isotopic partitioning between the matrix and chondrules. Tungsten is not abundant enough to have driven its own isotopic partitioning, but if tungsten were correlated with iron then ferromagnetic interaction grains could help explain both observations. We derive a practical parameterization for the increase in particle–particle collision rates caused by mutually attracting particle magnetic dipole moments. While the appropriate magnetic parameters remain uncertain, we show that ambient magnetic fields in protoplanetary disks are expected to be strong enough to magnetize iron metal bearing dust grains sufficiently to drive large increases in their collision rates. Such increased collision rates between iron-metal-rich grains could help preserve primordial iron and W isotopic inhomogeneities, and would help explain why the meteoritical record shows their partitioning in the solar nebula. The importance of magnetic interactions for larger grains whose growth is balanced by fragmentation is less clear and will require future laboratory or numerical studies.
L’idée régulatrice du temps absolu et son rôle dans la théorie kantienne de l’expérience
Authors: Beydoun Zaki
Published: July 2016

Nous tentons ici de démontrer que le concept du temps absolu, tel qu’il intervient dans le texte des « Analogies de l’expérience », renvoie à une idée régulatrice de la raison qui joue, dans la théorie kantienne de l’expérience, un rôle parallèle à celui qu’attribue Kant à l’idée régulatrice de l’espace absolu dans les Premiers principes métaphysiques de la science de la nature. Dans ce cadre, il s’agit d’établir une distinction nette entre l’idée du temps absolu et l’intuition pure du temps, ainsi que de démontrer que les principes dynamiques de l’entendement pur et, corrélativement, la possibilité de l’expérience, reposent sur cette idée.
Comment le capitalisme européen s’est-il emparé de l’histoire ?
Authors: Commetti Henri
Published: July 2016

Le récit européen raconte l’histoire moderne à partir du « moment axial » de la Renaissance sur le modèle de l’expansion d’un foyer culturel essentiellement actif jusqu’à produire le monde comme totalité unifiée dont s’empareraient les modes capitalistes de production. Telle est l’histoire-monde que cet article propose d’interroger : une histoire vue à travers une lorgnette européocentriste armée de macro-concepts dont la validité paraît problématique sitôt qu’on tente de les définir indépendamment de la version de l’histoire qu’ils permettent précisément de formuler. À travers ce récit s’opère la conquête des histoires humaines par l’histoire : l’Orient n’y est invité qu’à titre d’accessoire. Il y a dans le concept d’« histoire » non seulement la violence du discours qui nie, mais aussi un discours qui annule la réalité de cette violence, parce qu’il la rend impensable. Il s’agira, ici, de tenter de rompre avec l’asymétrie interprétative qui fonde ce grand récit univoque de l’Occident appelé « Histoire ».
« Ôter leurs majuscules aux concepts » Ethnographie d’un sport de combat
Authors: Lauret Pierre
Published: July 2016

Jérôme Beauchez est sociologue, maître de conférences à l’université de Lyon/Saint-Étienne, et membre de l’équipe « Cultures publiques » du Centre Max Weber. Dans son premier livre, L’Empreinte du poing. La boxe, le gymnase et leurs hommes 1 , il mène une enquête ethnographique au sein d’une salle de boxe anglaise d’une ville de l’Est de la France. Dans l’entretien qui suit, il revient sur les enjeux de l’ethnographie aujourd’hui, en situant son enquête à la convergence de la sociologie urbaine américaine de Mitchell Duneier, de l’anthropologie de Clifford Geertz et de la sociologie culturelle de Jeffrey Alexander. Il prend clairement ses distances avec l’ethnographie inspirée par la sociologie de Pierre Bourdieu. C’est l’occasion de constater que si l’ethnographie n’est pas tout à fait un sport de combat, elle constitue un champ de questions théoriques passionnées, et un instrument irremplaçable pour la découverte des mondes contemporains, de leurs drames, de leurs combats et des résistances qui s’y affirment.

Published: July 2016

Ce travail porte sur des cadres à potentiel (diplômés des grandes écoles ou diplômés universitaires) afin de mieux les comprendre et de mettre en place des pratiques plus adaptées à leur profil. Ainsi, nous avons étudié les valeurs professionnelles et les préférences quant au choix de poste selon les caractéristiques sociodémographiques (âge, sexe, situation conjugale, nombre d’enfants et origine sociale) et le type de diplôme (diplôme d’une grande école ou diplôme universitaire). Nous avons mis en évidence des facteurs influençant les valeurs professionnelles et les préférences d’emploi ainsi que des différences selon le diplôme et les caractéristiques sociodémographiques des individus. Ce travail peut donc aider les responsables des ressources humaines à concevoir une meilleure gestion des cadres selon leur profil.
La retractatio du Peristephanon 10 de Prudence par Flodoard à travers l’intertextualité épique
Authors: Leyronas Julie
Published: July 2016

Cette étude a pour objet le chapitre 14 du livre 1 du De Triumphis Christi Antiochiae gestis de Flodoard à travers une traduction inédite. Consacré à saint Romain, il constitue le seul récit de martyre du De Triumphis Christi Antiochiae gestis qui se présente explicitement comme une réécriture, en l’occurrence du Peristephanon 10 de Prudence qui ne compte pas moins de 1 140 vers résumés en 81 vers par Flodoard. Sous couvert de recourir à la breuitas, il transpose le texte de Prudence, qui écrit en mètre iambique, en hexamètres dactyliques. La retractatio de Flodoard efface le caractère théâtral du poème de Prudence pour accentuer la dimension épique du martyre de Romain. En faisant dialoguer les réminiscences du Peristephanon avec des réminiscences de la poésie épique païenne, il glorifie les victoires chrétiennes tandis que ces dernières permettent un renouveau de l’épopée.
La mémoire des figures impériales chez Claudien
Authors: Tournier Charlotte
Published: July 2016

Les poèmes politiques que Claudien a écrits pour l’empereur Honorius sont émaillés de références à des empereurs antérieurs, parmi lesquels Théodose, son père, et Trajan, modèle achevé de l’optimus princeps. L’objet de cet article est d’étudier comment, au travers de ces références, le poète entreprend de dessiner pour le tout jeune Prince d’Occident la figure du bon empereur et de définir sa légitimité (ainsi que celle du régent Stilicon, qu’aucune disposition légale ne justifie) entre transmission dynastique du pouvoir et choix du meilleur. Se voit ainsi précisé le fonctionnement du panégyrique impérial, qui ne se limite pas chez Claudien à la simple louange : le discours crée et met en forme sa propre réalité, jusqu’à se faire performatif et modeler le personnage loué. La perspective chronologique qui a été choisie montre en outre l’évolution du propos de Claudien à mesure qu’Honorius passe de l’enfance à l’âge adulte.

Published: July 2016

I tituli historiarum a tema biblico costituiscono un esempio interessante e poco studiato di Umdichtung, che si distingue all’interno della produzione epigrammatica della tarda antichità latina per il suo complesso statuto letterario. Tematicamente affini alla parafrasi biblica, i tituli si propongono come obiettivo la descrizione di raffigurazioni di tema biblico, essendo per questo aspetto eredi della tradizione antica dei “Bildepigramme”. Ad una presentazione delle principali caratteristiche di questo (sotto‑)genere letterario segue un saggio di commento – letterario, esegetico e iconografico – a Prud. ditt. XXXIV.
The Problems of Development Gap between Developed and Developing Nations
Authors: Mazumdar Debashis
Published: July 2016

The persistently large income gap between the Developed Countries (DCs) of the North and relatively Less Developed and Developing Countries (LDDCs) of the South is one of the most notable features of the international community over the last few decades. Such large disparities in income are paralleled by huge gaps in other non-monetary indicators of well being. Different research works in this field have indicated that the average annual growth rate of per capita income in LDDCs has been faster compared to that in DCs particularly since early 1990s indicating a sign of convergence in the growth process. However, the absolute gap between the DCs and LDDCs in terms of per capita GNP has widened over years. In this chapter, an attempt has been made to indicate the pattern of ß-convergence and s- convergence in income growth between DCs and LDDCs during 1960-2012. The study observes that there remains a definite indication of ß and s convergence in the growth rate of real PCI across different groups of nations particularly during the period 2000-2013.
Productivity Convergence and Asian Trade Blocks
Authors: Neogi Chiranjib
Published: July 2016

The present chapter tries to examine the trend of productivity growth and the process of convergence of productivity among the countries within three blocks viz., ASEAN, APEC and SAARC, using the data compiled by R. Summers and A. Heston in Penn World Table -Mark 5.6 and 7.1. Applying Galton model of the growth process it indicates that the countries within ASEAN and SAARC block do not show any convergence of productivity during the period 1960 to 2010. However, the countries within APEC show the sign of convergence of productivity. Standard tests for convergence show that only the APEC group of countries satisfies the test of absolute convergence that is significant whereas ASEAN and SAARC fail to satisfy the test of absolute convergence. The application of the test of conditional convergence on the ASEAN group of countries does not satisfy the criteria of convergence conditioned by the volume of investment but it shows strong tendency of conditional convergence of productivity among the countries of SAARC trade block.
Economic Convergence and Real Dimensions
Authors: Chakraborty Saptarshi
Published: July 2016

Economic convergence exists when two or more economies tend to reach a similar level of development and wealth. The idea of convergence in economics is the hypothesis that poorer economies' per capita incomes will tend to grow at faster rates than richer economies. Though income is considered to be an important indicator, it is now widely recognized that ‘real' dimensions like nutrition, health, shelter, education etc. assess the overall wellbeing of an individual/household. The objective of this chapter is to discuss and formulate a methodology by which one can measure shelter deprivation and its convergence in a region as a step forward to add on to overall well-being of an individual or household. This chapter not only shows a methodology to calculate such divergence and analyses the reasons for such divergence, but also prepares a list of possible combinations of policy prescriptions by which a policy maker, such as the government, can find the extent of rectification of shelter deprivation of a group given its allotment of budget.

Food security has emerged as one of the most significant and complex challenges of the twenty-first century. The region has made impressive achievements in reducing poverty and hunger in the past two decades, driven by impressive economic growth and rising incomes over the last few decades. This progress has however been uneven within and across states, and the region remains home to over 60% of undernourished people in the world. The objective of the chapter is to examine the status of food security of Asian economies. For that purpose, we have assessed and taken into account food security situation according to various indicators across different regions of Asia as well as average food production as indicator of food security for our analysis. We then endeavor to find whether there is any convergence of average food production across Asian countries. Lastly, we have tested whether average food production is a significant determinant of undernourishment for Asian countries. The results reveal that there is no convergence in average food production in Asia. However the panel regression exercise reveals that there is significant relationship between food security and undernourishment.

In today's sustainable world the thinking should be what is the life cycle costs, resources or supply chain process. The rapid industrialization had caused negative impact on the environment because of the increase in the pollution, waste, and rapid consumption of natural resources. This chapter is reviews the previous literature on current practices and future direction of Sustainable Supply Chain Management (SSCM), thus, it can increase practitioner's understanding of the importance and value of sustainable supply chain practices. A wide literature review is conducted to identify the relative important factors constitute of Sustainable Supply Chain Integration framework. Content analysis is introduced and applied for reviewing literature reviews of supply chain management, published in English-speaking peer-reviewed journals between 2000 and 2014. A descriptive evaluation of the literature body is followed by a content analysis on the basis of a specific pattern of analytic categories derived from a typical research process. With best understanding the concept of SSCM and gap identification from literature review, this chapter can contribute to extended model of SSCM and enhance firm competitiveness. This understanding is vital due to the increase of economic importance of sustainable supply chains in addition to their role in enhancing competitive power of companies in international markets.

Published: July 2016

It becomes more and more popular to use electric drives using rechargeable batteries as a replacement of traditional gas engines in vehicles and tools, or as a new assistive feature in e-bikes. Due to the high cost of batteries, industry and users demand better understanding of proper usage pattern of these batteries in terms of discharging/charging cycles in order to extend batteries’ life-time. In the ongoing research project PedElEc we work towards a better understanding of the ageing processes of e-bike batteries by observing groups of users applying different usage pattern. By doing so, we learn about long-term consequences of different usage pattern and compare them with regard to battery capacity and performance. In the end, we hope to be able to give valid recommendations on how to handle batteries in e-bikes with regard to discharging-charging cycles, acceptable storage of batteries, and preferable load.

Thai sausage or Isan sausage is a type of north eastern Thai cuisine which is famous for being served as an appitizer. Recently, Thai sausage production depends solely on manual tasks on stuffing and belaying the product, and as a result, it is hardly that the production can be well managed in terms of quantity, quality, and time. In this paper, we propose a novel design of semi-automatic system to improve the traditional Thai sausage production. Particulary, the machine is developed with a set of 24-volt, 36-watt,100-rpm DC motors used in both stuffering and belaying the materials, and it is mainly controlled by a programmable logic controller (PLC). Our design can yeild the product with short size of 4.5 cm and long size of 9 cm in length and both have the same 4 cm in diameter. On average, the output rates for the short-size products and the long-size products are 57 cm per minute and 71 cm per minute, respectively. This machine can improve production time compared to the previous process using manpower which can make short-size sausage and long-size sauge at 40 cm and 60 cm in one minute, respectively.
