Authors: Manner I. , Alanen A. , Komu M. , Savunen T. , Kantonen I. , Ekfors T. 
Published: June 2015

Purpose: The thermal effects of MR imaging in the presence of circular nonferromagnetic metallic implants were studied in 6 rabbits. Material and Methods: A sternotomy was performed and fixed with stainless steel wires, and small titanium rings (diameter 3 mm) were placed on the surface of the ascending aorta and subcutaneous tissue of the thigh. Four of the rabbits were exposed to an imaging procedure with a 1.5 T scanner applying a T1-weighted spin-echo sequence and a gradient echo sequence. Two of the animals served as unexposed controls. Thirty-six hours after the exposure, tissues adjacent to the implants were examined histologically and compared with corresponding samples of the control animals. Results: In the area of the titanium rings, histologic analysis revealed slight inflammatory changes apparently caused by the operation. No evidence of thermal injury was found, suggesting that the presence of the rings does not contraindicate MR examinations. Necrosis was noted in all of the sternal specimens. This was probably postoperative, but it impaired the assessment of thermal injury in this area.

Published: June 2015

Purpose: To evaluate the early effects of radiation on the liver using single photon emission CT (SPECT) with 99mTc-phytate combined with a pinhole collimator and MR imaging with superparamagnetic iron oxide (SPIO) and to compare 2 modalities regarding the assessment of the reticuloendothelial cell function. Material and Methods: The right sides of the livers of 12 anesthetized rats were irradiated with X-rays (4000 cGy). On the 3rd and 4th days postirradiation, SPECT and MR imaging pre- and postcontrast were performed. Results: On SPECT, the irradiated areas appeared as areas with reduced 99mTc-phytate uptake in 9 rats. In the remaining 3 rats, irradiated lesions were not evident on SPECT. On the early postcontrast MR images, differential negative enhancement of the irradiated and nonirradiated areas in the same 9 rats as on SPECT was apparent. However, on the later postcontrast images of 3 of these rats, the irradiated areas, which were brighter than the nonirradiated areas, were visually less clear than those on the earlier postcontrast images. In the remaining 3 rats, no radiation damage was evident on MR images. Conclusion: SPECT with 99mTc-phytate and early postcontrast MR imaging with SPIO can show early radiation damage of the liver. The serial assessment of the postcontrast MR images provides functional information on the Kupffer cells.

Authors: Kakitsubata Y. , Kakitsubata S. , Kiyomizu H. , Ogawa T. , Kato K. , Watanabe K. 
Published: June 2015

Purpose: Radiological findings were investigated in 6 cases of intrahepatic portal-hepatic venous shunt (IPHVS) without chronic liver disease. Material and Methods: Six patients with IPHVS were examined using US, CT and MR imaging. US was performed in all patients and color Doppler imaging in 5 patients. CT was performed after i.v. bolus injection of contrast medium in 4 patients. MR imaging and MR angiography were performed in one patient. Results: The shunt was present in the right lobe in 4 patients and in the left lobe in 2 patients. The shunts consisted of focally dilated or tubular vessels (1 aneurysmal) in 4 patients, and multiple small vessels in 2 patients. US revealed anechoic structures with various configurations at the shunt. Color Doppler imaging could detect blood flow in various directions in the shunt vessels in 5 patients. CT and MR images showed these abnormal vascular structures in the liver. MR angiography was also useful for evaluating the relationship between the portal and the hepatic veins. Conclusion: Color Doppler imaging was the best modality for evaluation of IPHVS.
Fragmented Platinum Microcoils as Embolization Material
Authors: Irie T. , Kusano S. 
Published: June 2015

Purpose: To evaluate the feasibility of using fragmented microcoils as embolization material. Material and Methods: Fragmented microcoil particles were produced from a coil of 0.42-mm platinum guide wire. The diameter of the particles was 420 μ and the length was 450–800 μ. To prevent the catheters from being obstructed by the particles, a core shaft wire was passed through the channels of the particles and a hollow plunger was used to release particles from the catheter. Forty particles were introduced into 4 kidneys in 4 adult dogs following transfemoral catheterization and systemic heparinization. Renal arteriography was performed immediately, and at 60 min, and at 3 weeks after embolization. Results: All particles were successfully introduced into the periphery of the kidneys, and caused occlusion within 3 weeks of embolization. Conclusion: Fragmented platinum microcoil particles can be used as embolization material to avoid catheter obstruction.

Purpose: To compare the performances of 4 imaging systems in the diagnostic radiology of the chest: an asymmetric screen-film combination (a-SFC); a conventional screen-film combination of speed class 200 (SFC); a screen-film combination of speed class 200 with an aluminium lung filter; and digital luminescence radiographs (DLR). Material and Methods: Object detectability studies were carried out using an anthropomorphic chest phantom. The images were obtained under standard exposure conditions at 125 kVp. The detection performance of the various systems was evaluated by receiver operating characteristic (ROC) analysis on the basis of a total of 12 240 observations. Results: In the overall evaluation the a-SFC and the SFC plus lung filter received equally high ratings of 0.878±0.018 and 0.860±0.21, respectively (p>0.05). There was no significant difference between the 200-speed SFC and the storage phosphor radiographs. In the mediastinum all the tested systems were clearly superior to the 200-speed SFC (p<0.05) while in the lung fields the 200-speed SFC received a high rating of 0.866±0.026. The a-SFC had slight advantages over the SFC plus lung filter and the 2 digital imaging modes (p>0.05). Conclusion: The a-SFC and the digital luminescence radiographs provide a significant gain in diagnostic information in the mediastinum without diminishing detail detectability in the lung fields and without additional radiation exposure.
Psychological flexibility in migraine: A study of pain acceptance and values-based action

Published: June 2015

Background Studies of musculoskeletal pain patients confirm that acceptance of pain and values-based action are strong predictors of pain-related disability and that interventions fostering “psychological flexibility” confer positive outcomes. However, data on these processes in migraine remain limited. This cross-sectional study examined relations between components of psychological flexibility and headache among treatment-seeking migraineurs. Methods A total of 103 adults ( M age = 41.5 (11.9) years; 88.2% female) with ICHD-confirmed migraine (71.8% episodic, 28.2% chronic) across three clinics completed measures of psychological flexibility and headache-related disability. Hierarchical regressions quantified relations between acceptance/values-based action and headache variables after first controlling for pain severity and gender. Results Acceptance of pain and values-based action accounted for 10% of unique variance in headache severity (Δ R2 p = 0.006) and up to 20% in headache-related disability (Δ R2 ps = 0.02 and < 0.001) but were weakly related to headache frequency. Psychological flexibility was more strongly associated with MIDAS-measured disability than was headache severity or headache frequency. Significant effects were typically of medium-to-large size and driven primarily by values-based action. Conclusions Paralleling results from the broader chronic pain literature, pain acceptance and values-based action play significant roles in headache pain and disability. Further study of interventions targeting these processes may enhance existing treatments.
Multivariate adaptive regression splines models for vehicular emission prediction
Authors: Oduro Seth Daniel , Metia Santanu , Duc Hiep , Hong Guang , Ha Q.P. 
Published: June 2015

Abstract
Background
Rate models for predicting vehicular emissions of nitrogen oxides (NO
X
) are insensitive to the vehicle modes of operation, such as cruise, acceleration, deceleration and idle, because these models are usually based on the average trip speed. This study demonstrates the feasibility of using other variables such as vehicle speed, acceleration, load, power and ambient temperature to predict (NO
X
) emissions to ensure that the emission inventory is accurate and hence the air quality modelling and management plans are designed and implemented appropriately.

Methods
We propose to use the non-parametric Boosting-Multivariate Adaptive Regression Splines (B-MARS) algorithm to improve the accuracy of the Multivariate Adaptive Regression Splines (MARS) modelling to effectively predict NO
X
emissions of vehicles in accordance with on-board measurements and the chassis dynamometer testing. The B-MARS methodology is then applied to the NO
X
emission estimation.

Results
The model approach provides more reliable results of the estimation and offers better predictions of NO
X
emissions.

Conclusion
The results therefore suggest that the B-MARS methodology is a useful and fairly accurate tool for predicting NO
X
emissions and it may be adopted by regulatory agencies.
Between mother tongue and ‘ceremonial tongue’: Boubacar Boris Diop and the self-translation of Doomi Golo
Authors: Carré Nathalie 
Published: June 2015

This article is a case study focusing on the not-so-common experience of writing and publishing in French as well as in an African language. Senegalese writer Boubacar Boris Diop decided to switch from French to his mother tongue, Wolof, after a stay in Rwanda as part of the ‘Rwanda,
écrire par devoir de mémoire’ project. This study focuses specifically on the novel Doomi Golo and on Diop’s self-translation of the text into French. What is at stake in the translation from Wolof to French? How has Boubacar Boris Diop managed to translate or transpose
his text for different audiences? To what extent have traditional literary patterns influenced the writing of the text? These are a few of the questions raised and discussed in this contribution.
Cette contribution se présente sous forme d’une étude de cas et s’intéresse
à une expérience encore relativement marginale dans le champ des littératures francophones: celle de l’écrivain sénégalais Boubacar Boris Diop. Représentant important de la littérature francophone durant les années 1980–2000,
celui-ci a en effet décidé d’effectuer un retour vers sa langue maternelle, le wolof, après un séjour au Rwanda dans le cadre de la résidence d’écriture ‘Rwanda, écrire par devoir de mémoire’. La présente
contribution s’intéresse en particulier à l’expérience d’auto-traduction que son premier roman en Wolof, Doomi Golo, a fait naître. Que se joue-t-il dans le travail de traduction entre Wolof et Français? Quelles nécessaires adaptations
/ transpositions se font jour? Comment les traditions littéraires (génériques et de réceptions) influencent-elles le texte même? Voici quelques-unes des questions abordées au long de cette contribution.
Identités multiples dans l’écriture francophone des Italiens de Tunisie: la mission de l’écrivain dans l’œuvre de Cesare Luccio (1906–1980)
Authors: Loreti Alessio 
Published: June 2015

This article focuses on Francophone Italian literature of Tunisia and more particularly on the work of Cesare Luccio (1906–1980). Halfway between French colonizers and colonized Tunisian, Italian emigrants challenged French acculturation in Colonial Tunisia. What are the motivations
that led Italian expatriates to experiment with forms of French writing? The first part of this article discusses the issues of identities and languages in a context of separations and shared cultures. It will then examine more deeply the Francophone work of Cesare Luccio, i.e. the novel Cinq
hommes devant la montagne (1933) and the collection of short stories Humbles figures de la cité blanche ou la Sicile à Tunis (1934). How does this writer consider his own community in his writings on the fringes of French and Italian literatures? What is the role of his French-speaking
literary work?
Cet article présente un regard critique sur la littérature italienne francophone de Tunisie à travers une analyse de l’œuvre de Cesare Luccio (1906–1980). À mi-chemin entre colonisateurs français et colonisés tunisiens,
les écrivains italiens de Tunisie sont confrontés à l’acculturation française. Quelles sont les motivations qui ont mené des émigrés d’origine italienne à expérimenter des formes d’écriture française
en Tunisie coloniale? La première partie de ce texte aborde les enjeux identitaires de cette littérature, à savoir la question de la langue, dans un contexte de séparations et de cultures partagées. Il s’agira ensuite d’examiner de plus près
l’œuvre francophone de Cesare Luccio, à savoir le roman Cinq hommes devant la montagne (1933) ainsi que le recueil de nouvelles Humbles figures de la cité blanche ou la Sicile à Tunis (1934). Quel regard porte l’écrivain sur sa propre communauté
dans ses écrits aux marges des littératures française et italienne? Quel rôle confie-t-il à son écriture d’expression française?

Abstract
With the proliferation of mobile and distributed systems capable of providing its geoposition and even the geoposition of any other element, commonly called point of interest, developers have created a multitude of new software applications. For this purpose, different technologies such as the GPS or mobile networks are used. There are different languages or formats used to define these points of interest and some applications that facilitate such work. However, there is no globally accepted standard language, which complicates the intercommunication, portability and re-usability of the definitions of points of interest currently in use. In this paper, we take the first steps towards a language and a development environment independent of the underlying technologies, allowing developers to define the points of interest in a simple and fast way, and automatically generate other different formats from the same definition that can be considered a bridge among current technologies. We use the Model-Driven Engineering approach, focusing on the creation of models to abstract the definition of systems from the underlying technologies.
Opening paper 2015- Some comments on Bioglass: Four Eras of Discovery and Development
Authors: Hench Larry L. 
Published: June 2015

AbstractHistorically the function of biomaterials was to replace diseased or damaged tissues. First generation biomaterials were selected to be as bio-inert as possible and thereby minimize formation of scar tissue at the interface with host tissues. Bioactive glasseswere discovered in 1969 and provided for the first time an alternative; strong, stable interfacial bonding of an implant with host tissues. In the 1980’s it was discovered that bioactive glasses could be used in particulae form to stimulate osteogenesiswhich thereby led to the concept of regeneration of tissues. This article summarizes the four eras of development of bioactive glasses that have led from concept of bioactivity to widespread clinical and commercial use, with emphasis on the first composition, 45S5 Bioglassr. The four eras are; A) Era of Discovery, B) Era of Clinical Application, C) Era of Tissue Regeneration, and D) Era of Innovation. Key scientific and technological questions answered for the first three eras are presented. Questions still to be answered for the fourth era are included to stimulate innovation in the field.

Published: June 2015

AbstractGenetic and environmental factors, especially nutrition and lifestyle, have been discussed in the literature for their relevance to epidemic obesity. Gene-environment interactions may need to be understood for an improved understanding of the causes of obesity, and epigenetic mechanisms are of special importance. Consequences of epigenetic mechanisms seem to be particularly important during certain periods of life: prenatal, postnatal and intergenerational, transgenerational inheritance are discussed with relevance to obesity. This review focuses on nutrients, diet and habits influencing intergenerational, transgenerational, prenatal and postnatal epigenetics; on evidence of epigenetic modifiers in adulthood; and on animal models for the study of obesity.

AbstractIn 2013, the World Health Organisation (WHO) released an update of the report on “Priority Medicines for Europe and the World” with the aim to bridge the gap between public health needs and the current research and development priorities. A number of emerging technologies are currently explored for their potential to respond to the identified unmet medical needs. Nanotechnology has the potential to offer scientific/technical solutions for some of these pharmaceutical gaps. The present report investigates to what extent projects funded by the European Commission will lead to innovative formulations as well as new therapeutic concepts, if clinical studies in European Member States investigating nanomedicines and finally if nanotech based products authorised in the European Union will contribute to identified public health needs.
Construction Of Hedonic Price Index For The “Most Liquid” Polish Painters
Authors: Kompa Krzysztof , Witkowska Dorota 
Published: June 2015

Abstract
Art market has been developing in Poland and the first Art Fund was established in 2011. Therefore it seems that investment in art can be considered as alternative form by Polish investors. In order to decide whether art is a good investment, it is necessary to evaluate expected returns which might be obtained from such investment thus an art price index should be developed. The aim of the paper is to discuss artworks as investment assets and evaluate price index of paintings produced by 11 Polish artists whose artworks were traded the most often on auctions that were held in Poland in the years 2007–2010. In our research, employing data concerning 750 objects, we apply the hedonic index methodology to estimate returns from the paintings market. The results of our investigation show that hedonic quality adjustment essentially influences evaluation of artwork prices therefore we propose the aggregated hedonic index which might better describe situation at the art market than the hedonic index biased by the specification of a single model.

Published: June 2015

AbstractIn this work, microwave energy is used for preparing a granular red mud (GRM) adsorbent made of red mud with different binders, such as starch, sodium silicate and cement. The effects of the preparation parameters, such as binder type, binder addition ratio, microwave heating temperature, microwave power and holding time, on the absorption property of GRM are investigated. The BET surface area, strength, pore structure, XRD and SEM of the GRM absorbent are analyzed. The results show that the microwave roasting has a good effect on pore-making of GRM, especially when using organic binder. Both the BET surface area and the strength of GRM obtained by microwave heating are significantly higher than that by conventional heating. The optimum conditions are obtained as follows: 6:100 (w/w) of starch to red mud ratio, microwave roasting with a power of 2.6 kW at 500℃ for holding time of 30 min. The BET surface area, pore volume and average pore diameter of GRM prepared at the optimum conditions are 15.58 m2/g, 0.0337 cm3/g and 3.1693 A0, respectively.
No More Battles – User-centric Approaches as Key to Successful Intranets
Authors: Wagner Anne Christine 
Published: June 2015

Abstract
In the short history of intranets a lot of IT-centric paradigms have been prevailing (tool choice, architectural questions, overall IT strategy). The emergence of intranet paradigms, referred to as Web2.0, as well as changed user expectations due to consumerization and high adaption of mobile devices challenge the traditionally technology-driven approach in enterprises: Today, users realize that there is more to claim and fight for. This article introduces approaches that start from the practitioner's perspective and help to align users, IT and strategic stakeholders with the purpose of forming an alliance between them and of finding the scope and design that fits all requirements.

Published: June 2015

Abstract
Mobile devices and associated applications (apps) are an indispensable part of daily life and provide access to important information anytime and anywhere. However, the availability of university-wide services in the mobile sector is still poor. If they exist they usually result from individual activities of students and teachers. Mobile applications can have an essential impact on the improvement of students’ self-organization as well as on the design and enhancement of specific learning scenarios, though. This article introduces a mobile campus app framework, which integrates central campus services and decentralized learning applications. An analysis of strengths and weaknesses of different approaches is presented to summarize and evaluate them in terms of requirements, development, maintenance and operation. The article discusses the underlying service-oriented architecture that allows transferring the campus app to other universities or institutions at reasonable cost. It concludes with a presentation of the results as well as ongoing discussions and future work.
