Published: October 2015

Este trabalho objetivou a comparação da fenologia de fitofisionomias de cerrado e classes de cobertura da
terra utilizando o Índice de Vegetação por Diferença Normalizada (NDVI) na Bacia Hidrográfica do rio São
Marcos. As etapas de trabalho foram: (1) identificação espacial de cada classe de cobertura da terrautilizando
o mapa de vegetação PROBIO; (2) vetorização de amostras em cada uma das áreas; (3) extração das médias
de NDVI para todas as cenas MODIS entre os anos 2001 e 2011 e (4) elaboração dos gráficos da série
temporal para cada fitofisionomia e classe de cobertura da terra. Os resultados mostraram semelhança na
distribuição sazonal do NDVI para as áreas de savana parque e gramíneo-lenhosa, sendo que as diferenças
anuais se dão em função da época chuvosa ou seca. A área de agricultura apresentou diferença anual mais
abrupta devido à ocorrência de monocultura. Na área de atividade pecuária ocorreu diferença sazonal em
função das épocas chuvosa e seca, e alteração para valores maiores de NDVI a partir do ano 2005,
possivelmente pela inserção de pastagem plantada no local. A utilização do NDVI permitiu a comparação
entre afenologia dasfitofisionomias e o entendimento da dinâmica de cobertura da terraque ocorre na área de

Discusiones en torno al rol asignado a la inteligencia militar en la Argentina contemporánea
Authors: Tello Ángel Pablo , Spota Julio César
Published: October 2015

En el presente artículo de investigación nos proponemos indagar en la función asignada a la Inteligencia Militar por parte del Estado argentino. El propósito específico del trabajo implicó efectuar un ejercicio de interrogación sobre el papel jugado por la inteligencia militar del país austral dentro del esquema estratégico nacional. A tales efectos encausamos la investigación evaluando el grado de compatibilidad existente entre la apreciación estratégica general manejada por la dirigencia política argentina (caracterizada por una apreciación regional ‘pacificada’ en términos inter-estatales) y la asignación diferencial de partidas presupuestarias entre los distintos componentes del instrumento militar nacional en beneficio de la Inteligencia Militar. En relación con el plano metodológico articulamos un ejercicio de análisis comparativo de información cuantitativa recabada sobre los presupuestos nacionales –local y regionales– junto con la realización de una serie de entrevistas efectuadas a personal de inteligencia civil y militar, cuyo eje central fue determinar la interpretación de los acontecimientos en curso desde el enfoque propio de los miembros de los servicios de inteligencia. Los resultados alcanzados nos condujeron a formular una hipótesis: el Estado argentino lleva a cabo actividades ilegales de inteligencia interior utilizando segmentos de la estructura de la Inteligencia del Ejército para lograr su propósito.
Drones: ¿Hacia una guerra sin regulación jurídica internacional?
Authors: Villamizar Lanús Fernando
Published: October 2015

Dadas sus ventajas, los drones se están convirtiendo en un arma fundamental en los conflictos armados contemporáneos. Este artículo tiene como objetivo dar respuesta a algunas preguntas relacionadas esa realidad: ¿Qué tan adecuada es la normatividad internacional para regularlos? ¿Será el Derecho Internacional Humanitario (DIH) la forma de evitar que se causen estragos ilimitados? ¿Será posible aplicar algún tipo de estatuto diferente al DIH para regular el uso de los drones? ¿Cómo opera el DIH cuando el Estado usa drones contra actores armados no estatales o éstos los utilicen contra el Estado? La metodología para responder a esos interrogantes consistirá en revisar y cotejar la acción de los drones con respecto al Derecho de la Guerra Aérea, al Derecho de Ginebra y a las normas sobre el uso de drones en el espacio exterior. Se encontrará que pese a la obsolescencia y generalidad de algunas normas, el DIH es plenamente aplicable al uso de los drones con fines bélicos.

Se utilizó el método documental y descriptivo; el primero, por la consulta realizada a diferentes documentos científicos en internet; y el segundo porque de la información encontrada en la web se extrajo, describió e interpretó lo más trascendente de determinada culturas, personalidades y organizaciones. Teniendo presente que quienes conocen una sola representación cultural, argumentan que podrían tener un conocimiento de las características culturales de otros lugares, cuando en realidad no es así. Siglos atrás las religiones ya ofrecieron normas de conducta y valores para que las personas implementen en su diario vivir y más aún al libre comercio local e internacional. Por esta razón las personas de diferentes dogmas (Hindú, Cristiana, Islámica, Budistas, etc.) desean conocer cómo implementar sus creencias para el entorno empresarial para una mejor comprensión entre las partes y crear sinergias entre ellas (religión- cultura - comercio).
Individual and demographic consequences of reduced body condition following repeated exposure to high temperatures
Authors: Gardner Janet L. , Amano Tatsuya , Sutherland William J. , Clayton Mark , Peters Anne
Published: October 2015

Although the lethal consequences of extreme heat are increasingly reported in the literature, the fitness costs of exposure to sublethal high air temperatures, typically identified in the 30–40°C range, are poorly understood. We examine the effect of high (≥35°C) daily maxima on body condition of a semiarid population of White‐plumed Honeyeaters, Ptilotula penicillatus, monitored between 1986 and 2012. During this 26‐yr period, temperature has risen, on average, by 0.06°C each year at the site, the frequency of days with thermal maxima ≥35°C has increased and rainfall has declined. Exposure to high temperatures affected body condition of White‐plumed Honeyeaters, but only in low‐rainfall conditions. There was no effect of a single day of exposure to temperatures ≥35°C but repeated exposure was associated with reduced body condition: 3.0% reduction in body mass per day of exposure. Rainfall in the previous 30 d ameliorated these effects, with reduced condition evident only in dry conditions. Heat‐exposed males with reduced body condition were less likely to be recaptured at the start of the following spring; they presumably died. Heat‐exposed females, regardless of body condition, showed lower survival than exposed males, possibly due to their smaller body mass. The higher mortality of females and smaller males exposed to temperatures ≥35°C may have contributed to the increase in mean body size of this population over 23 years. Annual survival declined across time concomitant with increasing frequency of days ≥35°C and decreasing rainfall. Our study is one of few to identify a proximate cause of climate change related mortality, and associated long‐term demographic consequence. Our results have broad implications for avian communities living in arid and semiarid regions of Australia, and other mid‐latitudes regions where daily maximum temperatures already approach physiological limits in regions affected by both decreased precipitation and warming.

Published: October 2015

In preparation for developing a website to enhance emotional wellness and healthy lifestyle during the perinatal period, this study examined women’s informational needs and barriers. Seventy-four women who were pregnant or had given birth completed an online survey inquiring about information needs and preferred sources related to psychosocial aspects and lifestyle behaviors. Information related to healthy diet choices and weight management, followed by exercise, was rated highly as a need. Information related to depression, stress, and anxiety was also rated as important. Health-care providers and the Internet were found to be preferred sources of information. Evidence-based websites can serve as a powerful low-cost educational resource to support and reinforce the health promotion advice received from their health-care providers.
Research on the Influence of Anti-fatigue Effect and Movement Ability of Blueberry Polysaccharides on Aged Mice
Authors: Bo Bai
Published: October 2015

The article introduces functions as well as extraction and purification of polysaccharides, and the effect of blueberry polysaccharides (BPs) on movement endurance, anti-fatigue capacity and related physiological indexes in aged mice induced by D-galactose is going to be investigated. The method of water extract-alcohol precipitation is used in the experiment to extract polysaccharides from blueberries, andin-vitrooxidation resistance and bacteriostasis of polysaccharides are studied after preliminary purification so as to provide a reference for the production and application of blueberry polysaccharides. Mice are randomly divided into a normal control group, an aged model group, a BP low-dose group, a BP medium-dose group, and a BP high-dose group. After the administration of BPs for 20 consecutive days, the exhaustive swimming time and fatigue indexes are determined. The results show that BPs could prolong the exhaustive swimming time, decrease the content of BUN, BLA and MDA, and obviously increase the activity of HG, MG, SOD and LDH. To conclude, BPs have good anti-fatigue effect. This study may provide theoretical evidence for the development of anti-fatigue drugs from BPs.
The Research on the Impact of Green Beans Sports Drinks on Relieving Fatigue in Sports Training
Authors: Qi Li , Ying Liu
Published: October 2015

For researching the function of relieving fatigue of green beans sports drinks, this paper selected 60 mice as subjects. They were randomly divided into four groups (low dose group, middle dose group, high dose group and physiological saline group). Each time they were respectively feed 10g 20g/L, 40g/L, 80 g/L green beans sports drinks and 15ml/(kg.d) physiological saline. The experiment lasted for a month. We recorded weight of mice, swimming time and blood urea nitrogen indicators. The results show that green beans sports drinks can significantly prolong swimming time of mice (p <0.05). For serum urea the results show no effect. So green beans sports drinks have a certain function of relieving physical fatigue.
Aflatoxin B1 adsorption by the natural aluminosilicates - concentrate of montmorillonite and zeolite
Authors: Markovic Marija , Dakovic Aleksandra , Rottinghaus George , Stojanovic Mirjana , Dondur Vera , Kragovic Milan , Gulisija Zvonko
Published: October 2015

Aflatoxin B1 adsorption by the concentrate of bentonite clay -
montmorillonite and the natural zeolite - clinoptilolite and was investigated
at the initial toxin concentration 4 ppm, with different amonunts of solid
phase in suspension (10, 5, 2 and 1 mg/10 mL) and different pH values - 3, 7
and 9. Results indicated that for both minerals, decreasing the amount of
solid phase in suspension, decrease the amount of active sites relevant for
adsorption of aflatoxin B1. Thus, for concentrate of montnorillonite, at the
lowest level of solid phase in suspension (1 mg/10 mL), aflatoxin B1
adsorption indexes were 97% at pH 3, 88% at pH 7 and 82% at pH 9, while for
the natural zeolite, adsorption of toxin was 9% at pH 3 and 7% at pH 7 and 9.
Since inorganic cations in minerals are mainly responsible for aflatoxin B1
adsorption, even the natural zeolite - clinoptilite has much higher cation
exchange capacity (the content of inorganic exchangeable cations) compared to
the concentrate of montmorillonite, adsorption of aflatoxin B1 by this
mineral is much lower. Comparing the molecular dimensions of aflatoxin B1
molecule with the dimension of channels of clinoptilolite and interlamellar
space of montmorillonite it is obvious that this toxin is adsorbed only at
the external surface of clinoptilolite while in the montmorillonite all
active sites are equally available for its adsorption. Thus, the concentrate
of montmorillonite posess by higher adsorption capacity for aflatoxin B1.
Results presented in this paper confirmed the fact the differences in the
structure of minerals led to their different efficiency for adsorption of
aflatoxin B1. Mineralogical and chemical composition, determination of cation
exchange capacity, etc., are very important parameters influencing the
effectiveness of minerals as aflatoxin B1 adsorbents. [Projekat Ministarstva

Application of mixture experimental design in formulation and characterization of solid self-nanoemulsifying drug delivery systems containing carbamazepine
Authors: Krstic Marko , Ibric Svetlana
Published: October 2015

One of the problems with orally used drugs is their poor solubility, which
can be overcame by creating solid self-nanoemulsifying drug delivery systems
(SNEDDS). Aim is choosing appropriate SNEDDS using mixture design and
adsorption of SNEDDS on a solid carrier to improve the dissolution rate of
carbamazepine. Self-emulsifying drug delivery systems (SEDDS) consisting of
oil phase (caprilic-capric triglycerides), a surfactant (Polisorbat 80 and
Labrasol? (1:1)) and cosurfactant (Transcutol? HP) are formed by applying
mixture design. 16 formulations were formulated, where proportion of lipids,
surfactant and cosurfactant were varied (input parameters) in the following
ranges: 10-30%, 40-60%, 30-50%, respectively. After dilution of SEDDS with
water (90% water), the droplet size and polydispersity index (PdI) of the
obtained emulsions (output parameters) were measured using photon correlation
spectroscopy. After processing data, appropriate mathematical models that
describe the dependence of input and output parameters were selected. The
optimized SNEDDS was adsorbed on the carbamazepine and solid carrier physical
mixture, containing 20% carbamazepine. Neusilin? UFl2, Neusilin? FL2,
Sylysia? 320, diatomite were used as the carriers. The ratio of
SNEDDS:carrier varied (1:1, 2:1). Dissolution testing was carried out in the
rotation paddles apparatus. Caracterization of solid SNEDDS was performed
using the hot stage microscopy (HSM), thermogravimetric analysis (TGA),
differential scanning calorimetry (DSC), infrared spectrophotometry with
Fourier transformation (FT-IR), scanning electron microscopy (SEM) and X-ray
diffraction (PXRD). Selected SNEDDS consisting of lipids (21.12%), surfactant
(42.24%) and cosurfactant (36.64%) had a droplet size 157.02?34.09 nm and PDI
0.184?0.021. Drug release profiles showed that in all formulations
dissolution rate increased (the fastest drug release was observed in
formulations with Sylysia? 320). It can be concluded that in all formulations
carbamazepine is present in the thermodynamically most stable polymorphic
form III. Formulation of solid SNEDDS can significantly increase dissolution
rate carbamazepine, with conservation of the polymorphic form III CBZ and
potentially increased bioavailability.

Cook and Thomas, LLC: Balancing Auditor Liability, Client Confidentiality, and the Public Interest
Authors: Brasel Kelsey R. , Daugherty Brian E.
Published: October 2015

In this case students are asked to assume the role of Alex Trifold, CPA, an audit partner for the public accounting firm, Cook and Thomas, LLC, who holds going concern information about an audit client that may impact other entities audited by Cook and Thomas. The case study illustrates how adherence to auditing standards may place auditors in a difficult situation when balancing the auditor's risk of litigation, the clients' rights to confidentiality, and the auditor's duty to the public. Additionally, the case provides exposure to prior litigation cases against auditors with unfavorable outcomes when auditors chose to protect their client's confidentiality, and, conversely, in cases where auditors chose to protect the greater public interest. The case requires students to engage in critical thinking by providing their viewpoints as to the optimal balance of limiting auditor liability, adhering to client confidentiality requirements, and simultaneously serving the public interest. The case study is appropriate for both undergraduate and graduate auditing courses.
Facilitating Student Learning in Accounting through Scaffolded Assessment
Authors: Abraham Anne , Jones Hazel
Published: October 2015

With the emergence of new sets of technological tools, university students are now offered more authentic learning experiences involving real-world, complex problems and their solutions. This focus on problem-based activities and case studies has produced a learning environment that is inherently multidisciplinary. This paper reports on the development of a scaffolded learning assignment with blended components applied in an accounting subject that was taught in a cross-disciplinary setting. The assignment was developed in a sociocultural context, based on a Vygotskian approach, and this paper details its design and development. The five stages of the assignment were carefully scaffolded and included elements of individual and group tasks, finishing with an individual reflection on the process. Formative assessment and associated feedback are important elements of the scaffolding and thus the paper reports both the design and implementation of the assignment, and provides qualitative feedback from students regarding how completing the assignment enhanced their learning in accounting. The paper concludes with suggestions for further applications for the learning design of the assignment.
How Categorisation Shapes the Attitude–Behaviour Gap in Responsible Consumption
Authors: Antonetti Paolo , Maklan Stan
Published: October 2015

Scholars have documented that many consumers have positive attitudes towards responsible products but do not consistently buy these alternatives. In this paper we present a new perspective, based on categorisation theory, to examine the attitude–behaviour gap. Through a qualitative study, we identify two dimensions that influence consumers’ categorisation of ethical products: (1) construing the decision as altruistic or self-interested and (2) perceiving the context of the behaviour as private or public. Using these dimensions to assess the consumption situation, consumers construe four types of responsible purchase that rest on different motivations. Analysing the categorisation process allows a more nuanced understanding of the potential reasons that underpin the attitude-behaviour gap. We show that the inconsistency between words and deeds has different explanations depending on the frame applied by consumers to the decision, and suggest that a deeper understanding of framing processes is necessary for the development of more effective marketing strategies.
The Best Times to Call in a Mobile Phone Survey
Authors: Vicente Paula
Published: October 2015

Establishing contact with the sample units is an important part of the survey response process, and an efficient calling schedule is critical to achieve high response rates. The rapid increase in mobile phone ownership has triggered the interest of marketing researchers in the use of mobile phones for collecting survey data about consumers. Mobile phone surveys may favour establishing contact with sample units since the mobile phone is a personal device carried at all times, thus making the person permanently contactable. This paper aims to identify the best times to call in a mobile phone survey by investigating the influence of the day and time of the call on the likelihood of establishing contact and obtaining an interview. A three-level ranking of calling periods, based on call efficiency, is proposed. Outcomes also revealed that the level of efficiency of calling periods is not dissociated from respondents’ socio-demographic characteristics, namely in terms of age and region of residence.
A New Approach to Network Analysis for Brand Positioning
Authors: Wang Hui-Ju
Published: October 2015

The purpose of this paper is to expand the domain of brand positioning measurement by demonstrating how network analysis techniques are used in brand positioning research. Using 12 sample brands in the electronic industry, this paper proposes a four-step process as a practical guide in analysing the effects of brand positioning on differentiation. Through the techniques of core-periphery structure, the paper creates four clusters to reveal differentiation of brand positioning. It provides clear arguments for using network analysis as the preferred method to capture the structure of brand positioning. The results have significant theoretical and practical implications for academic researchers and practitioners in the field of brand management.
Knowledge Sharing in IT Consultant and SME Interactions
Authors: Bradshaw Adrian , Pulakanam Venkateswarlu , Cragg Paul
Published: October 2015

Many small and medium enterprises (SMEs) depend on consultants to overcome knowledge barriers, especially for IT projects. This paper aims to determine how IT consultants affect the IT knowledge of SMEs when IT consultants and SMEs interact. Data were collected using face-to-face interviews with both IT consultants and SME managers. The study is the first to identify what and how SMEs learn from consultants during an IT implementation project. Consultants help SMEs gain different types of knowledge, employing a broad range of knowledge sharing mechanisms. As consultants are an important part of the knowledge creation processes of SMEs, SMEs should strive to form long-term relationships with consultants and use these interactions to develop IT knowledge within the SME.
Who Needs to be Informed? – Empirical Results From a Field Experiment on The Adoption of IOIS Among SMEs
Authors: Kreuzer Stanislav , Born Friedrich , Bernius Steffen
Published: October 2015

Inter-organizational information systems (IOIS) play a critical role in today’s organizations and their relationships with business partners. While large organizations already began utilizing IOIS at the outset, small and medium-sized enterprises (SME) have subsequently been reluctant to adopt and use IOIS. As such systems are subject to high network effects, a firm thus has to reach out especially to its SME partners to achieve a critical mass of adopters among them. Prior research agrees that the provision of support in terms of circumstantial information and expertise can influence organizational adoption decisions. However, research in this direction has remained inconclusive. This study conducts a controlled field experiment at the organizational level to investigate the provision of support as a non-coercive persuasion strategy to foster the adoption of IOIS among 203 SME business partners of a large German organization. A cluster analysis is further conducted to identify distinct clusters of IOIS adopters showing significantly different adoption rates that result from informing them as a strategy. The results first offer evidence for the importance of informing SMEs as a viable strategy to foster IOIS adoption among them. Furthermore, the results provide empirical evidence for the presence of particular arrangements of characteristics describing the strategy and structure of analyzed organizations that ultimately interact with the effect of the provision of support as a persuasion strategy.
A review of studies on information systems and SMEs in high ranked IS journals (2000-2014)
Authors: Parker Craig M. , Burgess Stephen , Al-Qirim Nabeel
Published: October 2015

This paper identifies novel approaches to future small and medium enterprise (SME) research from a review of articles, and then introduces the papers in this AJIS special section which evidence these approaches. More specifically, the paper makes an important contribution by reviewing 61 articles in high ranked IS journals (2000-2014) and introducing three new facets which are used to analyse research on SME adoption/use of IS (units of analysis, SME sizes and SME types) not considered in previous literature review studies. These facets provide the basis for proposing various future research opportunities. The editorial then introduces the four papers in this special section covering the research theme on SMEs, and highlights the contributions they make using the three facets.
How to Improve Sustainability and Environmentally Friendly Behaviour in Automatic Dishwashing? Example: Germany
Authors: Bichler Sandra , Gorny Susanne , Seifert Monika , Kessler Arnd , Stamminger Rainer
Published: October 2015

Decreasing resource consumption concerning electricity, water and detergents in the framework of automatic dishwashing is not only determined by technical improvements. First and foremost, the use phase, in other words, the consumers and their choices, for example, the type of dishwasher, the kind of dishwashing programmes selected and the method of pretreating dishes, play an important role in terms of saving energy. To investigate the current dishwashing habits in Germany, 4 000 private households were asked about the usage of automatic dishwashers and the general dish treatment in everyday life. The results of the survey have shown a broad range of consumer behavior due to individual dishwashing habits. It also became obvious that consumers who more frequently use the energy saving “eco programme” tend to pretreat some dishes, such as pots and pans, with additional resources more often than the households who use other programmes. Therefore, the study reveals that a holistic view due to all resources consuming dishwashing steps is necessary to deduce adequate consumer recommendations for saving energy, water and detergents.
The Effect on Solution Properties of Replacing a Hydrogen Atom with a Methyl Group in a Surfactant
Authors: Raykundaliya Nirav , Bordes Romain , Holmberg Krister , Wu Jun , Somasundaran Ponisseril , Shah Dinesh O.
Published: October 2015

Two surfactants, namely, dodecanoylglycinate and dodecanoylsarcosinate, differing only in a methyl group vs. a hydrogen atom on the amide nitrogen, have been studied with respect to solution behavior and adsorption at the air–water, oil-water and calcium carbonate-water interfaces. It was found that the ability of the glycinate surfactant of forming intermolecular hydrogen bonds via the amide group leads to tighter molecular packing, which greatly influenced the behavior at interfaces. Based on this molecular observation, potential applications were considered and emulsification, foaming and wetting tests were carried out. It could be concluded from this work that a minor change in the structure of a surfactant molecule can be very significant for technological systems and processes.
Synthesis and Properties of 1,2,3,4-Butanetetracarboxylic Acid Type Gemini Surfactants with Semifluoroalkyl Chain as Hydrophobic Group
Authors: Kawase Tokuzo , Nomura Yoshifumi , Oida Tatsuo
Published: October 2015

Two kinds of 1,2,3,4-butanetetracarboxylic acid type gemini surfactants having semifluoroalkyl groups (Rf-(CH2)n-; Rf = C8F17, n = 2,3,4,5,6,8,11) as diester of 2,3-bis-COOH and 1,4-bis-COOH were prepared from 1,2,3,6-tetrahydrophthalic anhydride as the key material. Their surface properties were studied by surface tension and surface pressure-area (π–A) measurements. Semifluoroalkylated geminis showed excellent surface tension re-ducing ability, but the values of the critical micelle concentration (CMC) and γCMC remained nearly unaffected by the methylene chain length. From the zero-pressure molecular areas of semifluoro-alkylated geminis and the compression modulus analysis, it was clarified that semifluoroalkylated gemini surfactants having short methylene chains would form more rigid monolayers than those having long methylene chains. But, there were not very large differences in surface properties between two geminis having the same methylene chain length.
Erosion Damage to Last-Stage Compressor Disk of a Heavy-duty Gas Turbine Engine
Authors: Neidel A. , Gädicke T. , Wallich S.
Published: October 2015

In the course of a service life extension after 100 000 operating hours, the rotor of a heavy-duty gas turbine was inspected. During the visual inspection, some compressor wheel disks, particularly in the last stage, showed conspicuous features and flawed material. The only causal damage mechanism worth considering is erosion: only very little deformation was found in the metallographic sections' microstructure immediately underneath the flawed material areas (wear or deformation induced damages would have lead to more deformation) and, what is more, the microstructure showed no evidence of corrosion. In accordance with VDI guideline 3822, the exact designation of the damage mechanism is “Flow wear in the form of sliding jet wear in the two-phase mixture gaseous/solid”.

Inconel 625, Inconel 600, Inconel 800H were friction surfaced on steel and Inconel substrates. The interface between steel and Ni-based alloys showed intermixing of two alloys while the interface between two Ni-based alloys showed no such intermixing. The XRD results confirmed that this intermixed zone consisted of mechanical mix two separate metals and no intermetallics were noticed. Friction surfaced Inconel coatings were metallurgically bonded to steel and Inconel substrates with out any physical defects such as voids or cracks. Friction surfaced coatings showed equiaxed fine grained microstructures (4–18 µm) compared with their consumable rod counterparts (12 – 85 µm). Scanning electron microscope electron backscattered diffraction results showed that the coatings consisted of mainly high angle grain boundaries indicative of dynamic recrystallization mechanism. The temperatures recorded using Infra Red camera showed that the temperature attained at the interface between rod and the substrate is about 1100 °C. The grain size of the consumable rod was relatively fine near the coating/substrate interface and relatively coarser away from interface indicating the change in strain and temperature the rod experienced at or away from the interface.
Quantitative Classification and Assessment of Sr Modification in Hypoeutectic Al-Si and Al-Si-Mg Alloys
Authors: Rossi P. , Engstler M. , Mücklich F.
Published: October 2015

This work focuses on quantitatively characterizing and classifying the modification of Al7Si and Al7Si0.3Mg casting alloy microstructures. Different levels of modification were induced through the addition of Sr and varying cooling rates during solidification. Firstly, a round robin test (RRT) was developed in which representative micrographs were subjectively evaluated by a group of experts in the area of aluminum casting alloys, from thirteen different laboratories. Secondly, a quantitative evaluation of the micrographs was conducted using an image analysis software. Lastly, a classification model was generated with the help of a data mining software, combining the quantitative data and the experts' evaluations. Different classes of microstructures were quantitatively defined, allowing objective assessment of the microstructures. Additionally, a quantitative degree of modification (M), which depends on the microstructure homogeneity, was developed to evaluate the modified microstructures. The result of this work lays the foundation for a forthcoming study of the quantitative correlation between process settings, microstructures, and casting properties.

To understand the dynamics of ice shelves, a knowledge of their internal and basal structure is very important. As the capacity to perform local surveys is limited, remote sensing provides an opportunity to obtain the relevant information. We must prove, however, that the relevant information can be obtained from remote sensing of the surface. That is the aim of this study. The Jelbart Ice Shelf, Antarctica, exhibits a variety of surface structures appearing as stripe-like features in radar imagery. We performed an airborne geophysical survey across these features and compared the results to TerraSAR-X imagery. We find that the stripe-like structures indicate surface troughs coinciding with the location of basal channels and crevasse-like features, revealed by radio-echo sounding. HH and VV polarizations do not show different magnitude. In surface troughs, the local accumulation rate is larger than at the flat surface. Viscoelastic modelling is used to gain an understanding of the surface undulations and their origin. The surface displacement, computed with a Maxwell model, matches the observed surface reasonably well. Our simulations show that the surface troughs develop over decadal to centennial timescales.
‘Doing her spiriting’: Lady Morgan's Irish Tempests
Authors: Seynhaeve Benedicte , Ingelbien Raphaël
Published: October 2015

Several studies have tried to answer the question ‘where is Ireland in The Tempest?’, while others have assessed Ireland's sense of its own postcoloniality through Irish writers' engagement with Shakespeare's most ‘colonial’ play. This essay argues that Lady Morgan's national tales offer the first significant Irish rewritings of The Tempest. It shows how her allusions to the play constitute coherent intertextual patterns, informed by a clear sense of parallels between the enchanted isle of Shakespeare's imagination and Ireland around the time of the Act of Union. Those parallels, however, challenge the idea that The Tempest illustrates a (post)colonial relation between Ireland and Britain. Instead, Morgan's focus on the spells cast on foreign visitors by the island and by the native magic of Prospero and Ariel suggests that she used the play in order to allegorize possible ways of making the Union work, rather than to impugn the illegitimacy of colonial rule. Her last and most pessimistic national tale embryonically sketches a wild, native Irish Caliban who would later recur in both British and Irish imaginations with the rise of militant radical nationalism, but Morgan's version of the figure still shows important differences with subsequent postcolonial embodiments of Irish otherness. Although seminal in many ways, Morgan's rewritings of The Tempest only later make room for more conflictual uses of the play as an allegory of British-Irish relations.
‘Nauseous Tides of Seductive Debauchery’: Irish Story Papers and the Anti-Vice Campaigns of the Early Twentieth Century
Authors: Rains Stephanie
Published: October 2015

This essay explores the relationship between anti-vice campaigns and the popular publishing industry of early-twentieth century Ireland. Specifically, it argues that there existed an informal but strongly symbiotic relationship between the two. The Irish anti-vice campaigns emphasised their objections to imported ‘pernicious literature’ in the form of British newspapers and story papers, thus allying themselves with both religious and nationalist movements of the time in Ireland. The Irish popular press, especially the story papers in direct and unequal competition with their large-scale British equivalents such as the Boys Own Paper, were able to use these moral attacks upon their competitors to position themselves as alternative leisure reading which was both wholesome and patriotic. This essay examines the ways in which Irish story papers such as the Emerald and Ireland's Own were able to use social purity rhetoric as a marketing technique against their British competitors. This occurred even though, as the essay outlines, in many cases the content of their stories was equally sensationalist and also had a strong emphasis upon violence, lurid plotlines and sometimes even sexually-suggestive advertising. Despite this, the anti-vice campaigns reserved their condemnations almost entirely for British publications, thus maintaining a co-operation with Irish publications which benefitted both parties.
Snail Conversions: Derrida's Turns with Ponge
Authors: Marder Elissa
Published: October 2015

Conversion is at work in prayer, promise, psychoanalysis and poetry. This paper begins by turning around Jacques Derrida's discussion of the importance of ‘anasemic conversion’ (linguistic traces not yet or no longer endowed with meaning) in the work of Nicolas Abraham and turns into a reading of the aneconomic effects of the silvery trail deposited by the eponymous snails in Francis Ponge's prose poem ‘Escargots’ (Snails). Anasemic conversion wrests language from meaning and returns it to its material, non-mattering, primal matter. Made of slimy spit, the snail's trail is not a product per se, but rather a by-product, an excessive residue, perhaps even a waste product. This silvery wake is a poetic amalgam of all elements pertaining to the snail's vital activities (expression, secretion, affection, excretion) and converts snails’ life experiences into a photographic figure of writing, a critique of an anthropocentric aesthetic, and a poetic death sentence.
Without Grace (a working title)
Authors: Connors Clare
Published: October 2015

This essay takes up Derrida's discussion in ‘Force and Signification’ of reading and writing as a ‘strange labour of conversion and adventure in which grace can only be absent [l'absente]’. It focuses on the ideas of work, the oeuvre, labour and travail in Derrida and Cixous, and in J. M. Coetzee's Disgrace. And it pursues the thinking of a work other than that fetishized by conservative ideologues, and links this to the work of fiction, and of the novel. While it eschews any theological debate about the relationship between grace and works, some space is left open here for the advent of grace, the absent one.
An Inexperience
Authors: Wood Sarah
Published: October 2015

‘This experience of conversion’ is a phrase of Derrida's. It struck me as something that couldn't be imagined: ‘not an as if.’ Nor a fantasy, nor a pretence. Not mediated. A magic word. That is what I managed to imagine. I had no idea (that is, no image) how to bring an experience of conversion about—not for myself, still less for you. But, I told myself, a word can be read, and read out. And I told myself: the point, with a word like this, is to speak it, or speak to it …

Design and Characterization of a High-Precision Digital Electromagnetic Actuator with Four Discrete Positions
Authors: Petit Laurent , Dupont Erwan , Doré Emmanuel , Lamarque Frédéric , Prelle Christine
Published: October 2015

A high-precision planar digital electromagnetic actuator with two displacement directions and four discrete positions is presented in this paper. The four discrete positions are located at each corner of a square cavity where a mobile permanent magnet moves thanks to Lorentz forces generated when a driving current passes through two orthogonal wires placed below the cavity. Four fixed permanent magnets are placed around the cavity in order to ensure high-precision magnetic holding of the mobile magnet at each discrete position. An analytical model of the actuator is presented and used to characterize its properties (switching time, energy consumption, and displaceable mass). Based on this model, an experimental prototype has been developed and then characterized. Comparisons between experimental and simulated results are carried out and show good agreement. The positioning repeatability errors have also been characterized according to the input signal in order to qualify the digital behavior of this high-precision actuator. Finally, an application of this digital actuator as a linear conveyor is presented and experimentally tested.
Double Properties of Novel Acylhydrazone Nanomaterials Based on a Conjugated System: Anion Binding Ability and Antibacterial Activity

Published: October 2015

A series of new compounds (1–12) containing 1,5-diaza-fluorenone, 1,10-phenanthroline-5,6-dione, ferrocene-1,1ʹ-dione, anthracene-9-carbaldehyde have been synthesized and optimized. The nanomaterials were also developed successfully. The binding properties were evaluated for biologically important anions (F−, Cl−, Br−, I−, AcO−, and H2PO4−) by theoretical investigation, UV-vis, and fluorescence experiments, and compound 6 displayed the strongest binding ability for AcO− ion among the synthesized compounds. Theoretical investigation analysis revealed that the intramolecular hydrogen bond existed in the structure of compound 6 and the roles of molecular frontier orbitals in molecular interplay. In addition, compound 6 showed wide antibacterial activity for colon bacillus, typhoid bacillus, and Pseudomonas aeruginosa, and inferior activity for hay bacillus and Staphylococcus aureus. This series of acylhydrazone nanomaterials showed double properties, anion binding ability, and antibacterial activity.
