Organization, Market Structure and Modus Operandi of the Guild-Organized Leather Manufacturing Industry in Tenth-Century Constantinople
Authors: Maniatis George C. 
Published: October 2011

Abstract
This article provides an in depth analysis of the organization, technology employed and functioning of the guild-organized leather manufacturing industry in the capital during the tenth century. Emphasis is placed on the internai organization and operations of the establishments; the technical processes employed; their business organization form and governing rules; the implications of the guild's occupational exclusivity; the likely market structure, degree of exercisable market power, and their impact on price competition. The scale of operations and growth of firms was determined by entrepreneurial decisions based on market signais. Prices and wages were set by market forces – not by the guild. Pro-competitive regulations and unimpeded new entry fostered correct business conduct and maintained a level playing field. Occupational exclusivity did flot ensure market monopoly, as the guiid system did not aim to promote the members' economic interests, thwart intra-guild and extemal competition, or achieve equality of economic resuits.
Sulle Nere Ali dei Sogni. Costantino Manasse e L'ambiguitá Onirica
Authors: Pizzone Aglae M. V. 
Published: October 2011

Abstract
Moving from four fragments of Aristander and Callithea (47, 103, 115, 152), this article explores the narrative and ideological meaning of dreams in Constantine Manasses' narrative. Fr. 47, in particular, encloses a quotation from Euripides (Hecuba 72), which has been put in connection with the commentary on Aristotle's work De divinatione per somnia written by Michael of Ephesus. Nevertheless the arguments for a direct connection between the two texts are not cogent. On the contrary there is a wide range of patristic, theological and philosophical texts showing a strong and ongoing interest in Byzantine culture for the psychological aspects of the oneiric processes. This background is reflected both in Constantine's novel and in his Chronicle, where he reworks and adapts the contemporary debates for narrative purposes.
Two Praises of the Emperor Manuel II Palaiologos: Problems of Authorship
Authors: Polemis Ioannis 
Published: October 2011

Abstract
An anonymous oration, praising the emperor Manuel II Palaiologos, has been recently published by Ch. Dendrinos, who treats it as a funeral oration. However, it is evident that the emperor was still alive at the time of the composition of that text, so we can safely assume that it was intended as a an encomium of the ruling emperor, and it was written some time after the death of the emperor's nephew John VII Palaiologos (1408). On the basis of some textual parallels between that anonymous text and the works of Makarios we put forward the hypothesis that the text published by Dendrinos was written by Makres himself. Finally an anonymous text praising Manuel II Palaiologos, attributed to Isidore of Kiev by G. Mercati, is published for the first time. That piece of oratory was composed shortly after Manuel's return from the West (1403).

ABSTRACTWe have explored the application of ion implantation as a tool for the enhancement of neural cell growth on glass surfaces. Glass substrates were ion implanted with gold and with carbon using a metal vapor vacuum arc (MEVVA) ion source-based implantation system at Ege University Surface Modification Laboratory. The implantation dose was varied over the range 1014 – 1017 ions/cm2 and the ion energy spanned the range 20 – 80 keV. B35 neural cells were seeded and incubated on the implanted substrates for 48h at 37°C. After 2-days in culture the cell attachment behavior was characterized using phase contrast microscopy. The adhesion and direct contact of neural cells on these ion implanted glass surfaces were observed

Abstract
In this study, more than 200 samples of drinking water from taps in the Silesian District (southern Poland) were analyzed. Concentrations of As, Bi, Cd, Co, Cr, Mo, Ni, Pb, Rb, Sb, Se, Te, Tl and V were measured using inductively coupled plasma-mass spectrometry technique (ICP-MS). The levels of the tested elements generally met European Union regulations. All analytical results were processed using computational methods, including the Pearson and Gini coefficients with the Lorenz curves, one-way ANOVA, the Kruskal-Wallis one-way analysis of variance, the Mann-Whitney U test, the variance correlation test and the Spearman’s test. In addition, Principal Component Analysis (PCA) with Varimax and Cluster Analysis with Ward’s Method were applied. It was shown, that some parameters (e.g. hardness and alkalinity) were highly correlated. The score plot described the degree of mineralization of water samples, so the origin of water could be easily determined. In turn, based on the created dendrogram, the division of samples into several groups (with soft, medium and highly mineralized water) could be deduced.

The nonlinear optical susceptibility and electro-optic tensor of ferroelectrics: first-principle study
Authors: Cabuk Suleyman 
Published: October 2011

Abstract
The nonlinear optical properties of some ABO3 materials (BaTiO3, KNbO3, LiTaO3 and LiNbO3) are studied by density functional theory (DFT) in the local density approximation (LDA) expressions based on first-principle calculations. Our goals are to give the details of the calculations for linear and nonlinear optical properties, including the linear electro-optic (EO) tensor for some ABO3 structures with oxygen octahedral structures using first-principles methods. These results can then be used in the study of the physics of ferroelectrics, specifically, we present calculations of the second harmonic generation response coefficient X
ijk(2) (−2ω, ω, ω) over a large frequency range for ABO3 crystals. The electronic linear EO susceptibility X
ijk(2) (−ω, ω,0) is also evaluated below the band gap. These results are based on a series of the LDA calculations using DFT. Results for X
ijk(2) (−ω, ω,0) are in agreement with experiments below the band gap. The results are compared with the theoretical calculations and the available experimental data.

Published: October 2011

Abstract
Intussusception in adults is a very rare entity that occurs in only 5% of all intestinal obstructions. Most often, in 66% of cases, intussusception is localized to the small intestine, while jejunogastric intussusception is very rare and occurs in 0,1%. Since the first case of jejunogastric intussusception after gastrojejunostomy was described by Bozzi in 1914, fewer than 200 isolated cases of postoperative intussusception after gastric surgery have been reported.
Here we present a case of anterograde jejunogastric intussusception, 15 years after radical subtotal gastrectomy with Billroth II anastomosis in a 71-year-old man.
Wettability of polypropylene capillary membranes during the membrane distillation process
Authors: Gryta Marek 
Published: October 2011

AbstractStudies of membrane wettability in the membrane distillation process were performed with the application of hydrophobic capillary membranes made of polypropylene. Three kinds of Accurel PP membranes (Membrana GmbH, Germany) differing in the diameter of capillaries and pores as well as in the wall thickness were used. It was confirmed that membranes with lower wall thickness and larger pore size provide higher yields of the process. The studies demonstrated that the pores of used membranes located close to the external surface of capillaries are several times larger than those located inside the membrane wall. Based on air permeability measurements it was found that external surface of the membranes with such large pores was completely wetted by water after 50–80 h of membrane distillation. However, the pores located inside the wall with the diameter below 1 μm were not wetted and electrical conductivity of the obtained distillate was maintained at the level of 3–6 μS cm−1.

Authors: Stanley Susanne H. , Laugharne Jonathan D. E. 
Published: October 2011

Objectives: People with a mental illness are more likely to experience poor physical health as compared to the general population. Currently, Australian mental health patients experience a relatively low level of physical health appraisal, prompting the development of the Clinical guidelines for the physical care of mental health consumers assessment and monitoring package. Method: The Clinical guidelines package takes an holistic approach, with a focus on the key dimensions of medication effects, lifestyle, existing or developing physical disorders, alcohol and illicit drug use, and psychosocial factors. Results: The package consists of a metabolic syndrome algorithm wall chart, a Clinician handbook, a Psychosocial assessment booklet, and a set of three screening forms. Conclusions: By taking a user-friendly, flexible, evidence-based approach, the resource can be used by all clinicians involved in the healthcare of people with a mental illness.
Les conséquences socio-spatiales des politiques de la vieillesse en milieu rural dans la région pays de la Loire
Authors: Blanchet Mickaël , Pihet Christian 
Published: October 2011

L’étude menée en 2011 sur les impacts géographiques des politiques de la vieillesse dans la région Pays de la Loire 1 indique que la prise en charge des personnes âgées dans les espaces à dominante rurale observés repose sur les structures médico-sociales héritées et demeure en marge des mutations sectorielles et économiques qui affectent l’action gérontologique. Il en résulte une moindre concentration et spécialisation de l’offre qui modèle les rapports entre les personnes âgées, les familles et les professionnels et tend à restreindre localement les trajectoires des personnes âgées en besoin.

Published: October 2011

En nous appuyant sur le triptyque de co-création proposé par le programme de recherche CreActE qui s'intéresse à la création d'activités nouvelles et d'emplois, nous proposons d'éclairer la situation et les dynamiques de création d'activités par les retraités (âgés de 60 ans ou plus). En effet, la localisation et le profil de ces retraités-créateurs sont mal connus et relativement sous-estimés. À partir d'une enquête postale transmise à 3336 retraités-créateurs de service, grâce au concours du RSI, sur huit départements des régions Rhône-Alpes et Auvergne, nous identifions les caractéristiques de ces retraités qui créent ou reprennent une activité à leur retraite, les motivations qui les poussent à créer, ainsi que les facteurs ayant freiné ou favorisé leur création. Nous dressons également deux portraits-types de retraités-créateurs : le retraité-créateur urbain autochtone et le retraité-créateur migrant vers le rural, qui peuvent constituer des opportunités de développement économique selon le profil du territoire concerné.
La généralisation des « prestations monétaires » en Europe
Authors: Le Bihan-Youinou Blanche 
Published: October 2011

Depuis les années 1990, l'introduction ou le développement de dispositifs visant à proposer aux personnes âgées en perte d'autonomie des prestations monétaires –dispositifs de cash for care – semblent se généraliser dans l'ensemble des pays européens. Si l'un des principaux arguments avancés pour défendre ce type de dispositif est celui du libre choix qu'il offre aux familles quant à l'organisation de la prise en charge de leur(s) parent(s) âgé(s), la situation est beaucoup plus complexe et ambigüe. Cet article interroge l'impact des prestations monétaires dans différents pays européens en s'intéressant aux processus de familialisation et défamilialisation du care et souligne l'importance de la contextualisation et de la régulation de tels dispositifs.
Vivre et dire la vieillesse à plus de 90 ans, se sentir vieillir mais ne pas être vieux
Authors: Balard Frédéric 
Published: October 2011

Définir la vieillesse n’est pas chose aisée car cette notion varie en fonction des sociétés et des représentations culturelles. Si la santé, la fonctionnalité (pouvoir effectuer normalement les tâches coutumières assignées aux adultes), l’autonomie et la sécurité sont des attributs apparemment transculturels autour desquels on analyse le vieillissement et l’entrée dans la vieillesse, ils ne suffisent pas à définir toutes les facettes du « vieux ». À travers l’analyse du discours et du vécu de nonagénaires et centenaires français, cet article propose d’explorer la vieillesse et de voir en quoi il est possible, à plus de 90 ans, de se sentir vieillir sans être vieux.
Working Memory Contributions to Reading Comprehension Components in Middle Childhood Children

Published: October 2011

Abstract
This study examined working memory contributions to reading comprehension subskills in Greek children (mean age 9 years, 1 month). The phonological loop of the Baddeley and Hitch working memory model was assessed with 3 recall tasks (words, nonwords, and digits) and a word list matching task. The central executive (CE) was assessed with 3 tasks (listening, counting, and backward digit recall). Participants were also given a receptive vocabulary task, a reading fluency task, and written stories accompanied by comprehension questions. Canonical correlation analyses showed that the comprehension variables were related to the CE rather than the phonological loop measures. CE functions were more strongly associated with elaborative inference generation (involving significant offline processing) and comprehension control (involving metacognitive monitoring). Smaller yet significant associations were observed between the CE and the necessary inference and literal comprehension measures, whereas a moderate relationship was found in the case of the simile comprehension variable. Among the CE variables, listening recall demonstrated the highest loading on the canonical function, followed by moderate yet significant counting and backward digit recall loadings. Vocabulary was found to fully mediate several associations between working memory and comprehension measures; however, the relationship between listening recall and elaborative inferences was partly mediated. Reading fluency and, on several occasions, Greek vocabulary knowledge did not mediate the relationships between CE measures and comprehension skills assessed. This study demonstrates the usefulness of CE measures for identifying young children’s possible difficulties in carrying out specific reading comprehension processes.

Published: October 2011

Several announcements in recent years by the United States and Canadian governments featuring their space exploration plan have one major thing in common: mission preparation at terrestrial analogue sites. Mission simulations carried out at these sites often involve traverses that allow access to areas of special interest needed to meet mission's objectives. Despite many recommendations, no WEB-based geographic information system exists for terrestrial analogues for mission planning. This paper reports the development of a WEB-based geographic information system for terrestrial analogues, illustrated using the example of the Haughton impact crater analogue site. This system demonstrates functionality that provides users with tools to plan their missions by enabling traverse planning between areas of interest based on a least cost path analysis method. The geographic information system will be composed of open source libraries and software, and will be compliant with Open GeoSpatial Consortium standards.
Amélioration du positionnement relatif temporel GPS avec les corrections GPS•C
Authors: Kirouac Valérie , Santerre Rock 
Published: October 2011

Le positionnement relatif temporel (PRT) est une méthode de traitement des observations GPS qui fonctionne selon le même principe que le positionnement relatif GPS conventionnel excepté que la différence d'observation s'effectue entre deux époques consécutives recueillies avec un seul et unique récepteur sans utilisation d'une station de référence à proximité. Cependant, les erreurs qui varient rapidement avec le temps doivent être tenues en compte adéquatement, en particulier les erreurs d'orbite et d'horloge des satellites ainsi que l'erreur liée à la perturbation des signaux dans l'ionosphère. Dans cet article, la contribution des corrections GPS•C, distribuées par le service CDGPS (Système de corrections GPS différentielles pan-canadien), dans l'amélioration de la précision du positionnement relatif temporel est démontrée. Une précision du positionnement horizontal de 30 centimètres (ou mieux) est conservée pour des intervalles de temps allant jusqu’à 20 minutes en appliquant les corrections GPS•C aux mesures de phase recueillies par un seul récepteur GPS mono-fréquence traitées en mode PRT. Sans ces corrections, les erreurs du positionnement relatif temporel se dégradent beaucoup plus rapidement.
Global Asymptotic Stability of PD Control for PM Stepper Motor Servo‐Systems
Authors: Carrillo‐Serrano R. V. , Hernández‐Guzmán V. M. , Santibáñez V. 
Published: October 2011

AbstractCommutation is a well‐known and successful strategy used in practice to control permanent magnet stepper motors. However, stability analysis has not been presented until now for this simple control strategy. In this note we prove, for the first time, that commutation achieves global asymptotic stability when used to regulate position in Euler–Lagrange systems actuated by permanent magnet stepper motors. Contrary to the traditional design methodology, this is accomplished by taking into account the electrical dynamics of the motors and, hence, we avoid the possibility of either performance degradation or instability due to the neglected electrical dynamics. We include high‐gain electric current loops and we introduce a saturated output feedback PD controller as the desired torque, i.e. velocity measurements are not required.
Relationships among service quality, corporate image, customer satisfaction, and behavioral intention for the elderly in high speed rail services
Authors: Kuo Chung‐Wei , Tang Mei‐Ling 
Published: October 2011

SUMMARYSince the Taiwan High Speed Rail operations, Taiwan's transportation market entered into a new era. Because of its competitive service of speed, convenience, environmental concerns and comfort, the High Speed Rail has not only made significant changes but has played a significant role in Taiwan's transportation. However, Taiwan now is an aging society. Due to the physical constraints among the elderly, demands to redesign the traffic system and maintain transportation safety are essential considerations. In the current market, Taiwan's transportation construction is facing fewer barriers; however, it must still improve, especially considering the health of the elderly. Thus, this study investigates elderly passengers' demands and further examined the relationships among service quality, corporate image, customer satisfaction, and behavioral intention. According to empirical analytical results based on structural equation modeling (N = 341), satisfaction directly affected travel behaviors, while service quality and corporate image played indirect roles. In addition, service quality plays a significant role on the effect of satisfaction. This study provides empirical evidence to indicate the quality of the accessible environment affects not only the effectiveness and efficiency of service quality, but also, the corporate image. The results provide valuable references for critically managing the elderly's usage of the high speed rail transportation service. Copyright © 2011 John Wiley & Sons, Ltd.
Power Plant Technologies for Low‐Enthalpy Geothermal Energy
Authors: Rohloff Kathrin , Kather Alfons 
Published: October 2011

AbstractWeltweit liegen in vielen Regionen keine geothermischen Hochenthalpie‐Ressourcen zur direkten Dampfnutzung vor. Aufgrund des oft geringen Temperaturniveaus sind angepasste Technologien zur Stromerzeugung erforderlich. Hierfür stehen zurzeit die Organic‐Rankine‐Cycle‐ und die Kalina‐Cycle‐Technologie zur Verfügung. Die Anlagen erfordern generell eine Gesamtoptimierung und weisen darüber hinaus einen hohen Eigenbedarfsanteil auf. Bei den in Deutschland vorliegenden Bedingungen sind so bereits Prozessbruttowirkungsgrade von bis zu 14 % erreichbar. Die Nettoanlagenwirkungsgrade, welche den Eigenbedarf und das Angebot der geothermischen Wärme berücksichtigen, liegen jedoch lediglich im mittleren einstelligen Bereich.

High Temperature Catalysis: Efficient Way for Chemical Conversion of Logistic Fuels
Authors: Deutschmann Olaf 
Published: October 2011

AbstractHeterogen katalysierte Gasphasenreaktionen bei hohen Temperaturen werden seit langem bei Energieumwandlungsprozessen eingesetzt, um effizient chemische Energieträger in Wärme, Strom und wertvollere chemische Energieträger zu wandeln. Aufgrund der hohen Temperaturen und kurzen Verweilzeiten sind die verwendeten Apparate durch komplexe, nichtlineare Wechselwirkungen zwischen Massen‐ und Wärmetransport sowie heterogene und mitunter auch homogene und elektrokatalytische chemische Reaktionen charakterisiert, deren Verständnis für Optimierung von Reaktordesign und Betriebsbedingungen Voraussetzung ist. Der Beitrag diskutiert die aktuellen Herausforderungen der Hochtemperaturkatalyse sowohl in der Grundlagenforschung als auch der Technologieentwicklung anhand von mit logistischen Kraftstoffen betriebenen Reformern zur Erzeugung wasserstoffreicher Reformate.
