Authors: Zeng Yan , Ma Hongfang , Zhang Haitao , Ying Weiyong , Fang Dingye 
Published: November 2014

Abstract
Ni-Al2O3 catalysts prepared by solution combustion method for syngas methanation were enhanced by employing various heating rate and different solvent. The catalytic properties were tested in syngas methanation. The result indicates that both of heating rate and solvent remarkably affect Ni particle size, which is a key factor to the catalytic activity of Ni-Al2O3 catalysts for syngas methanation. Moreover, the relationship between Ni particle size and the production rate of methane per unit mass was correlated. The optimal Ni-Al2O3 catalyst prepared in ethanol at 2°C/min, achieves a maximum production rate of methane at the mean size of 20.8 nm.

Published: November 2014

Abstract
Introduction. Currently tourist activity management is in need of creating special conditions for the development of integrated management tools based on the general information and analytical base. Material and methods. The creation of architecture and the content of geoinformation and hybrid information systems are oriented at the usage of the Integrated Tourist Spaces Management (ITSM) to set up a specific claim related to the features of management model. The authors created the concept of tourist space. The information and the analytical system are used to create the information model of tourist space. Information support development of ITSM system is a sort of a hybrid system: an expert system constructed on the basis of GIS. Results and conclusions. By means of GIS collecting, storage, analysis and graphic visualization of spatial data and the related information on the objects presented in an expert system is provided. The offered approach leads to the formation of an information system and the analytical maintenance of not only human decision-making, but it also promotes the creation of new tourist products based on more and more differentiated inquiries of clients or a ratio of the price and quality (from the point of view of satisfaction of inquiries).
Cerebral Toxoplasmosis in a Diffuse Large B Cell Lymphoma Patient
Authors: Savsek Lina , Opaskar Tanja Ros 
Published: November 2014

AbstractBackground. Toxoplasmosis is an opportunistic protozoal infection that has, until now, probably been an underestimated cause of encephalitis in patients with hematological malignancies, independent of stem cell or bone marrow transplant. T and B cell depleting regimens are probably an important risk factor for reactivation of a latent toxoplasma infection in these patients.Case report. We describe a 62-year-old HIV-negative right-handed Caucasian female with systemic diffuse large B cell lymphoma who presented with sudden onset of high fever, headache, altered mental status, ataxia and findings of pancytopenia, a few days after receiving her final, 8th cycle of rituximab, cyclophosphamide, vincristine, doxorubicin, prednisolone (R-CHOP) chemotherapy regimen. A progression of lymphoma to the central nervous system was suspected. MRI of the head revealed multiple on T2 and fluid attenuated inversion recovery (FLAIR) hyperintense parenchymal lesions with mild surrounding edema, located in both cerebral and cerebellar hemispheres that demonstrated moderate gadolinium enhancement. The polymerase chain reaction on cerebrospinal fluid (CSF PCR) was positive for Toxoplasma gondii. The patient was diagnosed with toxoplasmic encephalitis and successfully treated with sulfadiazine, pyrimethamine and folic acid. Due to the need for maintenance therapy with rituximab for lymphoma remission, the patient now continues with secondary prophylaxis of toxoplasmosis.Conclusions. With this case report, we wish to emphasize the need to consider cerebral toxoplasmosis in patients with hematological malignancies on immunosuppressive therapy when presenting with new neurologic deficits. In such patients, there are numerous differential diagnoses for cerebral toxoplasmosis, and the CNS lymphoma is the most difficult among all to distinguish it from. If left untreated, cerebral toxoplasmosis has a high mortality rate; therefore early recognition and treatment are of essential importance.

Abstract
Conchological Variability of Anadara inaequivalvis (Bivalvia, Arcidae) in the Black-Azov Sea Basin. Anistratenko, V. V., Anistratenko, O. Yu., Khaliman, I. A. - An alien species in the Black Sea and the Sea of Azov - Anadara inaequivalvis (Bruguiere, 1789) - was recently discovered to have a wide range of shell variability. From the investigated samples (over 900 valves) six basic types of the shell commissural opening were defined; they are not, however, discrete conditions. Th e presence of intermediate variants reveals a gradual (continuous) character of the shell variability and indicates that all the samples investigated belong to the same species. Th e variation of some other Anadara characteristics is also discussed, including: quantity and ornamentation of the ribs on the surface of the valves, quantity of chevrons on the ligament area, shape of the hinge plate and quantity of hinge teeth. A comparison of conchological characteristics of Anadara from the Black-Azov Sea Basin with A. inaequivalvis from southeast India shows that ranges and patterns of shell variability of Azov-Black Sea Anadara correspond to variability of A. inaequivalvis from this species type locality - Coromandel Coast of India.

Published: November 2014

Abstract
Birds as the Feeders of Ticks (Acari, Ixodida) in Megalopolis of Kyiv. Nebogatkin, I. V. - Data about ticks parasitizing on birds in the city of Kyiv were summarized. 117 birds and 27 nests were examined. Ticks were found on six species collecting food on the ground level: Great Tit (Parus major), White Wagtail (Motacilla alba), Rook (Corvus frugilegus), blackbird (Turdus merula), and Nuthatch (Sitta europaea). 56 Ixodidae specimens of four species from two genera were collected from the birds and their nests: Ixodes ricinus (Linnaeus, 1758); I. arboricola Schulze et Schlottke, 1930; I. lividus (Koch, 1844), Haemaphysalis concinna Koch, 1844. Th e role of birds as feeders of all developmental stages of ticks not only increases under conditions of urban landscape, but also becomes leading in the places with low population of small mammals. Ectoparasites of birds of the other taxonomic groups along with the ticks can play an important role in maintaining the circulation of pathogens of various aetiologies in the urban landscapes.
Communication, Respect, and Leadership: Interprofessional Collaboration in Hospitals of Rural Ontario
Authors: Morris Diane , Matthews June 
Published: November 2014

Purpose: Health care professionals are expected to work collaboratively across diverse settings. In rural hospitals, these professionals face different challenges from their urban colleagues; however, little is known about interprofessional practice in these settings. Methods: Eleven health care professionals from 2 rural interprofessional teams were interviewed about collaborative practice. The data were analyzed using a constant comparative method. Results: Common themes included communication, respect, leadership, benefits of interprofessional teams, and the assets and challenges of working in small or rural hospitals. Differences between the cases were apparent in how the members conceptualized their teams, models of which were then compared with an “Ideal Interprofessional Team”. Conclusions: These results suggest that many experienced health care professionals function well in interprofessional teams; yet, they did not likely receive much education about interprofessional practice in their training. Providing interprofessional education to new practitioners may help them to establish this approach early in their careers and build on it with additional experience. Finally, these findings can be applied to address concerns that have arisen from other reports by exploring innovative ways to attract health professionals to communities in rural, remote, and northern areas, as there is a constant need for dietitians and other health care professionals in these practice settings.

Authors: Danaher Kavanagh , Curley Tristaca 
Published: November 2014

Purpose: Coaches’ sports nutrition knowledge and subsequent nutrition recommendations can have an impact on athletes’ health and performance. The purpose of this study was to determine sports nutrition knowledge and nutrition recommendation practices of varsity coaches at one Canadian university and to determine if the coaches’ nutrition knowledge influenced nutrition recommendations to athletes. The coaches’ accessibility to sports dietitians was also examined.Methods: Coaches (n = 5) completed a modified psychometrically validated nutrition knowledge questionnaire and a semi-structured interview. Mean scores were calculated for questionnaire answers based on the correct answer and the coach's degree of certainty in their answer. Interviews were analyzed using thematic analysis.Results: Results showed a low nutrition knowledge, yet all coaches made nutrition recommendations to their athletes for fluid needs, dietary supplementation, and weight management; areas that may be potentially detrimental to the health of athletes. In addition, they made recommendations with regard to fluid needs, training diet, precompetition diet, recovery diet (i.e., post training or competition), dietary supplementation, and weight management; areas that could have potentially negative performance consequences to the athlete.Conclusions: It was determined that coaches had low nutrition knowledge scores and still made nutrition recommendations to athletes. The importance of sports dietitian involvement in varsity athletics is emphasized.
Assessment of Nutritional Adequacy of Packaged Gluten-free Food Products
Authors: Kulai Tasha , Rashid Mohsin 
Published: November 2014

Purpose: There is concern about the nutritional quality of processed gluten-free (GF) products. The aim was to investigate the nutrient composition and cost of processed GF products compared with similar regular products. Methods: Product size, price, caloric value, and macro- and micronutrient composition were compared between foods labeled “Gluten-free” and comparable regular products in 5 grocery stores in 3 Canadian cities. Data were calculated per 100 g of product. Results: A total of 131 products were studied (71 GF, 60 regular). Overall, calories were comparable between GF and regular foods. However, fat content of GF breads was higher (mean 7.7 vs. 3.6 g, P = 0.003), whereas protein was lower (mean 5.0 vs. 8.0 g, P = 0.001). Mean carbohydrate content of GF pasta was higher (78 vs. 74 g, P = 0.001), whereas protein (7.5 vs. 13.3 g, P < 0.001), fibre (3.3 vs. 5.8 g, P = 0.048), iron (9% vs. 25%DV, P < 0.001), and folate content (5% vs. 95%DV, P < 0.001) were lower. Mean price of GF products was $1.99 versus $1.23 for regular products (P < 0.001). Conclusions: Some commonly consumed packaged GF foods are higher in fat and carbohydrates and lower in protein, iron, and folate compared with regular products. GF products are more expensive. Dietitians should counsel patients on the GF diet regarding its nutritional and financial impact.
Pilot Evaluation of an In-Store Nutrition Label Education Program
Authors: Dukeshire Steven , Nicks Emily , Ferguson Jennifer 
Published: November 2014

Purpose: To describe and provide recommendations for the implementation of an evaluation for an already existing, in-store Nutrition Label Education Program (NLEP). Methods: We describe the development and implementation of an evaluation consisting of a pre- and postsurvey and one month follow-up. The evaluation was designed to assess satisfaction with the NLEP as well as changes in participant nutrition label knowledge, confidence in using nutrition labels, and actual changes in nutrition label use. Results: Nineteen participants took part in the pilot evaluation. The evaluation was successful in demonstrating high levels of satisfaction with the NLEP as well as positive changes in participant confidence and some increased knowledge in using nutrition labels. However, only 3 people participated in the follow-up, limiting the ability to assess behaviour change. Conclusions: Ideally, NLEPs should include ongoing evaluation that extends beyond just assessing participant satisfaction. Recommendations are provided for conducting such evaluations, including the importance of incorporating the evaluation into the program itself, using existing questionnaires when possible, and employing pre- and postsurveys as well as follow-up interviews to assess change.
L'utilisation de l'eau de mer dans la préparation des pâtes céramiques calcaires, premières observations sur les conséquences d'un tel traitement
Authors: Dufournier Daniel 
Published: November 2014

L'eau mer probablement utilisée sur
nombreux littoraux pour la préparation des pâtes céramiques. Les potiers tunisiens (à Naseul ou à Djerba) qui ont observé son pouvoir décolorant sur les argiles qu'ils exploitent l'utilisent pour fabriquer certains types de vases.
Le blanchissement qui résulte de l'utilisation de l'eau de mer
se manifeste uniquement pour les argiles riches en calcium. Les expériences réalisées montrent que la présence conjuguée du carbonate de calcium présent dans l'argile et des chlorures contenus dans l'eau de mer est responsable de cette décoloration.
Ce travail examine aussi l'influence de l'eau de mer sur la
composition chimique des pâtes calcaires. Elle se traduit par une augmentation des proportions de sodium et de magnésium et par une diminution importante du pourcentage de potassium. L 'élimination partielle de ce dernier élément tirerait également son origine de la présence conjointe du calcium et du chlore. Il est en outre démontré que la quantité de potassium perdu est une fonction croissante des teneurs initiales en calcium et en chlore de la pâte et de sa température de cuisson. Ces données éclairent d'un jour nouveau certaines anomalies de composition qui étaient jusqu'à présent mal perçues ou mal interprétées. Elles remettent aussi en question les modes opératoires de l'analyse chimique de certains constituants. *
Approche de l'artisanat du "Bronze" au Mont-Beuvray. La fabrication de fibules et l'organisation d'un atelier
Authors: Pernot Michel 
Published: November 2014

Le but de ce travail est de proposer une méthodologie pour apporter des éléments de réponse aux nombreuses questions que pose l'artisanat des alliages base cuivre des périodes protohistoriques. Par exemple : Qu'est-ce qu'un atelier ? Qu y produit-on ? Avec quelles technologies ?
La méthode utilisée fait appel, en interaction, à l'étude de la documentation des fouilles anciennes et à la fouille fine d'un site d'atelier. Des examens et analyses de laboratoire, des opérations d'archéologie expérimentale, et le nettoyage et l'étude de tous les matériels, sont mis en oeuvre. Cette démarche est appliquée au cas d'un atelier de la fin du 1er siècle avant notre ère du site du Mont-Beuvray en Bourgogne.
Dans le cas étudié, les résultats sont que l'on obtient la preuve de la fabrication de petits objets en laiton à 20% de zinc, dont des fibules en une seule pièce. Les différentes phases de la chaîne opératoire : fonderie, martelage et finitions ont été réalisées dans un espace de cinquante mètres carrés, certaines de ces phases peuvent être reliées à des structures et donc à la gestion de l'espace.
Apport de la méthode ICP-MS couplée à l'ablation laser pour la caractérisation des archéomatériaux

Published: November 2014

Au cours des années quatre-vingts, de nouvelles méthodes d'analyses ont été développées. Parmi celles-ci, l'ICP-MS semble pouvoir apporter une aide précieuse à la caractérisation des matériaux archéologiques. Le couplage récent de cette méthode avec l'ablation laser permet d'autre part d'envisager l'application de cette technique lorsque l'objet à analyser ne peut être échantillonné.
Après avoir décrit rapidement le principe de l'ICP-MS (Inductively Coupled Plasma Mass Spectrometry), nous étudierons l'intérêt du couplage de cette méthode avec l'ablation laser.
Nous présenterons ensuite les premiers résultats obtenus lors d'une étude conjointe réalisée au Service Central d'Analyse du CNRS à Solaize. Au cours de ce travail, des matériaux aussi divers que des métaux précieux (or et argent) et des matières siliceuses (verre et obsidienne) ont été étudiés.
Nous nous sommes plus particulièrement attachés à vérifier selon les types de matériaux étudiés :
- le caractère non-destructif de la méthode ;
- la reproductibilité et la représentativité des résultats. Pour cela, une comparaison a été effectuée entre les résultats obtenus par cette méthode et ceux obtenus sur les mêmes échantillons par les méthodes d'activation nucléaire développées au Centre E. Babelon pour ces matériaux ;
- les limites de détection de la méthode ;
- les éléments détectés par rapport aux problématiques archéologiques envisagées.
Le verre : les éléments de réponses que peuvent proposer les méthodes de caractérisation physico-chimiques aux problématiques archéologiques posées par ce matériau

Glass is a quite complexe archaeological material. Different ways to caracterize this matter exist depending on the problem to solve.
The first approach is a physical caractérisation of the corrosion phenomena sufferred by this material. These studies are necessary to try to answer the problems of conservation of glass. These problems are shortly described in this paper.
Other studies try to understand either the glass making recipies and techniques or the problems of trade and provenance posed by this material. The analytical methods used are essentially chemical analytical methods. A brief review of applications published by different authors is made here.
La monnaie Almoravide : de l'Afrique à l'Espagne.
Authors: Roux Corinne , Guerra M.F 
Published: November 2014

L'événement almoravide fut une véritable révolution. Une révolution non pas seulement politique, ni même sociale ou encore religieuse, mais avant tout une révolution économique. La clef de voûte de ce pouvoir, de ce renouveau politique du Maghreb extrême de la 2e moitié du XIe- 1ère moitié du XIIe siècle, est en effet de nature commerciale : la maîtrise du commerce transsaharien ramenant l'or depuis le pays noir jusqu'au nord musulman. La manifestation la plus éclatante de cette réussite étant la monnaie émise par le gouvernement almoravide.
L'outil monétaire apparaît, par conséquent, comme l'un des meilleurs indices de la santé de l'émirat berbère. L'association de la technique LA-ICP-MS à Factivation protonique, nous permet ainsi de mettre en évidence les phénomènes de monétaire, de même qu'elle nous laisse espérer identifier l'origine des minerais employés. De cette façon, en palliant les insuffisances des sources écrites, pourrons-nous saisir davantage l'histoire, qu'elle soit économique, sociale ou politico- militaire, de la dynastie almoravide.
Observations sur la conservation pollinique dans le remplissage de quelques grottes et abris paléolithiques du sud-ouest français et d'Algérie.
Authors: Fellag Hocine 
Published: November 2014

L'analyse pollinique du remplissage de quelques sites archéologiques en grotte du sud-ouest de la France et d'Afalou en Algérie a révélé des problèmes de conservation. Certains niveaux sont complètement stériles, d'autres ont conservé quelques grains qui appartiennent essentiellement, à la famille des Astéracées, notamment les cichoriées, à la famille des Pinacées (pin) et les spores de fougères. Ce sont des types polliniques particulièrement résistants aux de corrosion. Mis à part quelques cas où les résultats sont fiables, dans la majorité des échantillons étudiés, les données sont soit nulles soit biaisées, en raison des problèmes de conservation différentielles, rendant ainsi impossible paléoécologique.
Pour une meilleure estimation de la validité des résultats, il est important de relever l'état de conservation, la variété taxonomique, le nombre de grains, la concentration sporopollinique, le taux des indéterminables et la cohérence écologique. Dans cet article, les problèmes de conservation sont discutés et les raisons probables synthétisées.
Essais de caractérisation des silex bédouliens provençaux par analyse chimique élémentaire.
Authors: Blet-Lemarquand Maryse , Binder Didier , Gratuze Bernard 
Published: November 2014

This paper deals with the first results of chemical elementary analyse of early cretaceous flint from South Eastern
France. These flints have been exchanged, principally during the Neolithic, between the Alps and the Pyrenean. The
analyses concern geological samples, from a primary or secondary position, and archaeological samples as well. The latter
are coming from excavations concerning significant archaeological entities.
Raw and archaeological materials, attributed to several geological deposit (late cretaceous, tertiary) have been sampled to
contrast the results.
These analyses specially use LA-ICPMS, a non-destructive method whose results are compared with destructive ones
(liquid ICP MS, ARNC).
Several markers of provenance have been identified. These traces let us distinguish major geological deposits, and, let us
exceptionally establish differences between early cretaceous flints.
After this first approach, it will be necessary to increase the number of analysed samples and use a multidimensional
statistical treatment in order to specify the differences and variability observed.
