New geological model of the Lagoa Real uraniferous albitites from Bahia (Brazil)
Authors: Oliveira Chaves Alexandre 
Published: July 2013

AbstractNew evidence supported by petrography (including mineral chemistry), lithogeochemistry, U-Pb geochronology by Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS), and physicochemical study of fluid and melt inclusions by LA-ICP-MS and microthermometry, point to an orogenic setting of Lagoa Real (Bahia-Brazil) involving uraniferous mineralization. Unlike the previous models in which uraniferous albitites represent Na-metasomatised 1.75 Ga anorogenic granitic rocks, it is understood here that they correspond to metamorphosed sodium-rich and quartz-free 1.9 Ga late-orogenic syenitic rocks (Na-metasyenites). These syenitic rocks are rich not only in albite, but also in U-rich titanite (source of uranium). The interpretation of geochemical data points to a petrogenetic connection between alkali-diorite (local amphibolite protolith) and sodic syenite by fractional crystallization through a transalkaline series. This magmatic differentiation occurred either before or during shear processes, which in turn led to albitite and amphibolite formation. The metamorphic reactions, which include intense recrystallization of magmatic minerals, led uraninite to precipitate at 1.87 Ga under Oxidation/Reduction control. A second population of uraninites was also generated by the reactivation of shear zones during the 0.6 Ga Brasiliano Orogeny. The geotectonic implications include the importance of the Orosirian event in the Paramirim Block during paleoproterozoic Săo Francisco Craton edification and the influence of the Brasiliano event in the Paramirim Block during the West-Gondwana assembly processes. The regional microcline-gneiss, whose protolith is a 2.0 Ga syn-collisional potassic granite, represents the albitite host rock. The microcilne-gneiss has no petrogenetic association to the syenite (albitite protolith) in magmatic evolutionary terms.

AbstractThis study analyzes the relationship between Aerosol Optical Depth (AOD) obtained from Terra and Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) and ground-based PM10 mass concentration distribution over a period of 5 years (2008–2012), and investigates the applicability of satellite AOD data for ground PM10 mapping for the Croatian territory. Many studies have shown that satellite AOD data are correlated to ground-based PM mass concentration. However, the relationship between AOD and PM is not explicit and there are unknowns that cause uncertainties in this relationship.The relationship between MODIS AOD and ground-based PM10 has been studied on the basis of a large data set where daily averaged PM10 data from the 12 air quality stations across Croatia over the 5 year period are correlated with AODs retrieved from MODIS Terra and Aqua. A database was developed to associate coincident MODIS AOD (independent) and PM10 data (dependent variable). Additional tested independent variables (predictors, estimators) included season, cloud fraction, and meteorological parameters — including temperature, air pressure, relative humidity, wind speed, wind direction, as well as planetary boundary layer height — using meteorological data from WRF (Weather Research and Forecast) model.It has been found that 1) a univariate linear regression model fails at explaining the data variability well which suggests nonlinearity of the AOD-PM10 relationship, and 2) explanation of data variability can be improved with multivariate linear modeling and a neural network approach, using additional independent variables.

Authors: Renigier-Biłozor Małgorzata , Wiśniewski Radosław 
Published: July 2013

Abstract
This paper aims to determine the influence of selected variables on residential property price indices for the European countries, with particular attention paid to Italy and Poland, using a rough set theory and an approach that uses a committee of artificial neural networks. Additionally, the overall analysis for each European country is presented.
Quarterly time series data constituted the material for testing and empirical results. The developed models show that the economic and financial situation of European countries affects residential property markets. Residential property markets are connected, despite the fact that they are situated in different parts of Europe.
The economic and financial crisis of countries has variable influence on prices of real estate. The results also suggest that methodology based on the rough set theory and a committee of artificial neural networks has the ability to learn, generalize, and converge the residential property prices index.

Published: July 2013

Abstract
Seed pre-sowing magnetic field treatment was reported to induce biochemical and physiological changes. In the present study, response surface methodology was used for deduction of optimal magnetic field doses. Improved growth and yield responses in the pea cultivar were achieved using a rotatable central composite design and multivariate data analysis. The growth parameters such as root and shoot fresh masses and lengths as well as yield were enhanced at a certain magnetic field level. The chlorophyll contents were also enhanced significantly vs. the control. The low magnetic field strength for longer duration of exposure/ high strength for shorter exposure were found to be optimal points for maximum responses in root fresh mass, chlorophyll ‘a’ contents, and green pod yield/plant, respectively and a similar trend was observed for other measured parameters. The results indicate that the magnetic field pre-sowing seed treatment can be used practically to enhance the growth and yield in pea cultivar and response surface methodology was found an efficient experimental tool for optimization of the treatment level to obtain maximum response of interest.
Cartographical Aspects in the Design of Indoor Navigation Systems
Authors: Gotlib Dariusz , Marciniak Jacek 
Published: July 2013

Abstract
The development of indoor navigation systems should utilize advanced teleinformation, geoinformation and cartographical knowledge. The authors analyzed available specifications of prototypes of indoor navigation systems and drew conclusions about how to enhance the use of cartographical methods in the whole process of designing a new system. The analysis proves that cartographical methodology is still very limited in the process of designing indoor navigation systems. Researchers focus mainly on improving the positioning accuracy, and they often neglect the issue of developing spatial databases and the rules of their effective visualization. The process of designing indoor navigation systems, just like in the case of outdoor navigation systems, consists of a number of tasks that can be supported by the theory and practice of cartography. This article presents the issues of determination of spatial database model appropriate for an indoor system, improvement of accuracy of positioning algorithms utilizing spatial data and methodology of generating graphical and voice directions for indoor navigation. In the authors’ opinion, the discussed cartographical methods and techniques may considerably enhance indoor navigation systems and accelerate their development. The fundamental knowledge of cartographical methods should be within the interest of designers of these systems. At present the first attempts in this field may be observed, although they are still not mature and complex
Accuracy Performance Of E-Loran Receivers Under Cross-Rate Interference Conditions
Authors: Šafář Jan , Williams Paul , Vejražka František 
Published: July 2013

Abstract
According to a recent Business Case produced by the General Lighthouse Authorities of the United Kingdom and Ireland (GLAs), e-Loran is the only system that, when combined with GNSS, can achieve cost effective resilient Positioning, Navigation and Timing (PNT) by 2018 for maritime e-Navigation. The GLAs currently operate a trial e-Loran service from Harwich, UK and are working towards establishing e-Loran Initial Operational Capability (IOC) in the seven busiest UK ports and port approaches by mid-2013. A future extension of e-Loran coverage to the entire GLA service area will require the installation of additional transmitting stations. When planning the installation of e-Loran transmitters service providers will need a good understanding of the effects of the new signals on the system’s performance. Since all e-Loran stations share the same frequency band and the e-Loran signals propagate over vast distances, special attention needs to be paid to the issue of intra-system interference. This is also referred to as Cross-Rate Interference (CRI) and is inherent to the way e-Loran operates.
In this paper we examine the impact of CRI on the position accuracy performance of e-Loran receivers. First, a signal processing model for a typical e-Loran receiver is developed. This could provide the e-Loran community with a unified framework for receiver performance evaluation. Numerical and, where possible, analytical results obtained from the model are then presented, describing the achievable accuracy performance under different interference conditions. The theoretical results are also compared to those obtained from measurements made on a commercially available receiver driven by a signal simulator.
Our analysis shows that modern e-Loran signal processing algorithms can achieve a substantial reduction of the negative effects of CRI. However, there is still an appreciable residual effect, which should be taken into account when designing future e-Loran networks and determining their coverage and performance
Deterministic-Probabilistic Method of Waterway Design Parameters Determination
Authors: Gucma Stanisław , Zalewski Paweł 
Published: July 2013

Abstract
The paper presents a method of recommended waterway parameters determination, based on modified relationships derived from actual empirical research - the authors’ combination of PIANC and Canadian deterministic methods and stochastic relationships). These relationships are mostly discontinuous functions (e.g. of ship type variable, speed, method of determining the position, etc.), which can be approximated by continuous spline functions. Application built in C# allows determining the recommended minimum width of the waterway, the width increase due to the accuracy of the vessel positioning method, and the minimum radius of waterway bends. The results can be further utilized in the Decision Support System for Water Transport Safety.

Published: July 2013

Abstract
In this work the EGNOS performance before and after applying a novel methodology called Error Extraction is tested using real data. These data are collected at the EGNOS Monitoring Station placed in Sofia by Eurocontrol. The tests concern aircraft navigation, namely Approach with Vertical Guidance services. All results confirm that the designed new algorithms are very promising. They allow reduction of the error standard deviation and significant availability improvement without breaches of the integrity. The probability of system discontinuity decreases substantially.
On Computational Algorithms Implemented in Marine Navigational Software Used in Marine Navigation Electronic Devices and Systems
Authors: Weintrit Adam , Kopacz Piotr 
Published: July 2013

Abstract
In the paper the authors attempt to present the computational problem related to the navigational algorithm (meridian arc formula) implemented in the software applied in marine navigation electronic devices and systems, such as GNSS (GPS, GLONASS, Galileo), AIS, ECDIS/ECS, and other marine GIS.
From the early days of the development of the basic navigational software built into satellite navigational receivers, it has been noted that for the sake of simplicity and a number of other reasons, this navigational software is often based on the simple methods of limited accuracy. It is surprising that even nowadays the use of navigational software is still used in a loose manner, sometimes ignoring basic computational principles and adopting oversimplified assumptions and errors such as the wrong combination of spherical and ellipsoidal calculations in different steps of the solution of a particular sailing problem. The lack of official standardization on both the ‘accuracy required’ and the equivalent ‘methods employed’, in conjunction to the ‘black box solutions’ provided by GNSS navigational receivers and navigational systems (ECDIS and ECS) suggest the necessity of a thorough examination of the issue of sailing calculations for navigational systems and GNSS receivers
La fragilisation du rapport père/enfant. Une enquête auprès des pères divorcés
Authors: Bertaux Daniel , Delcroix Catherine 
Published: July 2013

Une enquête récente de l'INED a révélé que 54 % des enfants, dont les parents se sont séparés, perdent le contact avec leur père ou n'ont plus avec lui que des rencontres épisodiques. Des proportions voisines ont été trouvées dans d'autres pays européens ou aux Etats-Unis. Par contre, comme on pouvait s'y attendre, moins de dix pour cent des enfants de parents séparés perdent le contact avec leur mère. La différence des chiffres semble donc révélatrice d'une profonde dissymétrie entre les relations mère/enfant(s) d'une part, les relations père/enfant(s) de l'autre ; dissymétrie que le divorce (ou la séparation de couples non mariés) mettrait à jour.
Cette recherche effectuée par D. Bertaux et C. Delcroix pour la CNAF (programme Droit et évolution des formes de vie familiale) met en évidence certains des éléments qui structurent cette dissymétrie.
Vers un ethnoburb à la française ? Ancrages et diffusions des étrangers acquéreurs de biens immobiliers en Île-de-France
Authors: Desponds Didier , Bergel Pierre 
Published: July 2013

Aborder les transformations de la société sous l’angle des nationalités suscite des inquiétudes en France. Ces réticences dépassées, la difficulté demeure de mobiliser les données permettant de discerner les dynamiques à l’œuvre. Cet article s’appuie sur la base bien de la Chambre des Notaires de Paris, pour appréhender les logiques de distribution spatiale des acquéreurs de biens immobiliers de nationalité étrangère au sein de trois départements de la région Île-de-France. Discerne-t-on des spécialisations, ou des formes d’association, selon la nationalité ? La méthode quantitative employée cerne, à différentes échelles, les transformations en cours dans les périphéries parisiennes. Ces mobilités résidentielles résultent des stratégies complexes des ménages acquéreurs, ce qui requiert une approche qualitative. Ces transformations interrogent la pertinence de l’adoption du concept d’ ethnoburb de Li Wei dans le contexte francilien.
Géopolitique et métropolisation, le rôle de « minorité intermédiaire » des Juifs d'Istanbul
Authors: Morvan Yoann 
Published: July 2013

Cet article retrace les parcours résidentiels et identitaires des Juifs d’Istanbul, leurs trajectoires dans la mégapole turque et dans les différentes diasporas , suite à leurs migrations successives : Israël, France, Espagne, Amériques du nord et du sud. Il repose sur une enquête ethnographique menée au sein de la communauté entre avril 2009 et novembre 2012. À travers le concept de « minorité intermédiaire », il analyse l’évolution du rôle commercial des Juifs dans la métropole stambouliote à l’ère de la mondialisation. L’articulation entre la structure sociale interne de la communauté, notamment en matière de hiérarchie et de don, et son rôle externe permet de dresser une anthropologie économique de la minorité. Le concept de « minorité intermédiaire » révèle indirectement le processus de métropolisation d’Istanbul.
Horizons du mariage et critères de légitimité sur trois générations : établir, retenir et consentir
Authors: Ramos Gil Irene 
Published: July 2013

Cet article présente des récits de mariages d’hommes et de femmes vivant dans un village de la Costa Chica du Guerrero, recueillis au cours d’une recherche ethnographique. Leurs récits font transparaître des unions de différentes formes sur trois générations ainsi que la transformation des rapports d’autorité entre parents et enfants. L’autorité des parents qui prévalait dans la génération des grands-parents a été critiquée de façon persistante et par conséquent fragilisée, donnant lieu à l’acceptation de l’initiative des enfants pour choisir le moment, la façon et la personne avec qui ils se marieront. Cette transformation de la hiérarchie familiale est intelligible au travers des critères qui guident le jugement des acteurs de chaque génération quant à la légitimité du mariage : établir, retenir et consentir.
ON THE VERSATILITY OF VON WILLEBRAND FACTOR
Authors: Rauch Antoine , Lenting Peter 
Published: July 2013

Von Willebrand factor (VWF) is a large multimeric protein, the function of which has been demonstrated to be pivotal to the haemostatic system. Indeed, quantitative and/or qualitative abnormalities of VWF are associated with the bleeding disorder Von Willebrand disease (VWD). Moreover, increased plasma concentrations of VWF have been linked to an increased risk for thrombotic complications. In the previous decades, many studies have contributed to our understanding of how VWF is connected to the haemostatic system, particularly with regard to structure-function relationships. Interactive sites for important ligands of VWF (such as factor VIII, collagen, glycoprotein Iba, integrin aIIbb3 and protease ADAMTS13) have been identified, and mutagenesis studies have confirmed the physiological relevance of the interactions between VWF and these ligands. However, we have also become aware that VWF has a more versatile character than previously thought, given its potential role in various non-hemostatic processes, like intimal thickening, tumor cell apoptosis and inflammatory processes. In the presence review, a summary of our knowledge on VWF structure-function relationships is provided in the context of the "classical" haemostatic task of VWF and in perspective of pathological processes beyond haemostasis.

Published: July 2013

Objectives: This study aimed to compare polymerase chain reaction (PCR) and IgM detection using enzyme linked immune-sorbent assay (ELISA) in diagnosis of congenital cytomegalovirus (CMV) infection. Methods: This study was conducted from May 2009 to December 2010. Urine and blood samples were collected from 94 neonates with suspected congenital CMV infection. Serum and part of urine samples were stored at -20°C freezer, until the serologic and PCR tests were achieved. A 94 fresh urine samples were processed for cell culture. Nineteen (20.2%) out of 94 urine samples were proven positive for CMV infection by viral culture. For comparing PCR and IgM ELISA we used tissue culture technique as a reference, the 19 positive samples on culture (CMV group) and 20 negative samples (control group) were included in the comparison. Some characteristics of CMV and control groups were compared including sex, age, birth weight, gestational age < 37 and small for gestational age. Clinical and laboratory abnormalities were also compared in both groups. Results: This study showed that the sensitivity and specificity of PCR in relation to viral culture were 100% and 100% respectively, there was excellent agreement between both tests (Kappa coefficient was 1 and P=0.000). On the other hand, the sensitivity of IgM CMV ELISA in relation to viral culture was 63.2% and the specificity was 85%. There was good agreement between both tests (Kappa coefficient was 0.48 and P=0.002). By comparing CMV and control groups, there were high statistically significant differences between both groups as regard the birth weight, gestational age < 37 and small for gestational age items (P= 0.00, 0.03 and 0.01 respectively). There were statistically insignificant differences as regarding the clinical and laboratory abnormalities detected for neonates of both groups. In this study jaundice (63%) and hepato-splenomegaly (42%) were the most common clinical signs in both groups. Conclusion: PCR is more sensitive and specific technique for detection of congenital CMV infection than CMV IgM ELISA. Being more cost effective, less cumbersome and less time consuming in relation to viral culture, PCR may be used in detection of congenital CMV infection.
THE ROLE OF BLEEDING HISTORY AND CLINICAL MARKERS FOR THE CORRECT DIAGNOSIS OF VWD
Authors: Tosetto Alberto 
Published: July 2013

Quantification of the bleeding severity by use of bleeding assessment tools (BAT) and bleeding score (BS) has been consistently shown to improve the clinical diagnosis of von Willebrand disease (VWD) while helping researchers establish phenotype/genotype correlations. Subjects with a BS equal or higher than 3 may be consider having a bleeding tendency, and should be referred for a laboratory investigation, particularly for VWD. In the diagnosis of type 1 VWD, the use of the BS has been shown to be highly specific (>95%) with reported sensitivities ranging from 40 to 100%. The BS is related to all available measurements of von Willebrand factor activity, including the PFA-100 closure time. Therefore, in clinical practice the use of BAT should always be the first step to standardize the assessment of patients with suspected VWD. The use of the recent ISTH consensus BAT is suggested to harmonize the collection of bleeding symptoms in patients with a suspected or confirmed hemostatic disorder, particularly VWD. The ISTH BAT is also coupled with a Web-based repository of bleeding symptoms, therefore providing an integrated framework for collaboration in the field of clinical evaluation of VWD and mild bleeding disorders.
Transcending Triples
Authors: Dubinko Micah 
Published: July 2013

Semantic modeling to date has been largely an exercise in considering the whole world as triples (or at least, n-way tuples). Efforts to bridge the XML gap such as XSPARQL have focused on low-hanging syntactic fruit, and have not had much effect on deeper layers of the architecture.
In semantic modeling, common situations that are supposedly bread-and-butter for RDF, for example tracking provenance or recording facts known to a certain probability, give rise to complexity such as the much reviled RDF reification, or statements about statements. Even the W3C RDF Primer doesn't seem altogether comfortable with it:

While there are applications that successfully use reification, they do so by following some conventions, and making some assumptions, that are in addition to the actual meaning that RDF defines for the reification vocabulary, and the actual facilities that RDF provides to support it.

In a similar vein, inference is commonly viewed in the semantic world as something that produces (only) triples from (only) triples. A broader view of inference encompassing XML documents and values as inputs and outputs can make many common use cases far more straightforward. This paper discusses a (hypothetical?) world where triples and documents get along better with each other, and speculates about what future products fusing these technologies might look like.
