Analysis of water level variations in Brazilian basins using GRACEA comparison between daily in-situ water level time series measured at ground-based hydrometric stations (HS - 1,899 stations located in twelve Brazilian basins) of the Agência Nacional de Águas (ANA) with vertically-integrated water height anomaly deduced from the Gravity Recovery and Climate Experiment (GRACE) geoid is carried out in Brazil. The equivalent water height (EWH) of 10-day intervals of GRACE models were computed by GRGS/CNES. It is a 6-year analysis (July-2002 to May-2008). The coefficient of determination is computed between the ANA water level and GRACE EWH. Values higher than 0.6 were detected in the following basins: Amazon, north of Paraguay, Tocantins-Araguaia, Western North-East Atlantic and north of the Parnaíba. In the Uruguay (Pampas region) and the west of São Francisco basins, the coefficient of determination is around 0.5 and 0.6. These results were adjusted with a linear transfer function and two second degree polynomials (flood and ebb period) between GRACE EWH and ANA water level. The behavior of these two polynomials is related to the phase difference of the two time series and yielded four different types of responses. This paper shows seven ANA stations that represent these responses and relates them with their hydro-geological domain.

Comparison of column-coupled electrophoresis with liquid chromatography methods in food analysis of quinineComparison of column-coupled electrophoresis with liquid chromatography methods in food analysis of quinine (QUI) is presented in this work. The capillary isotachophoresis (CITP) on-line coupled with capillary zone electrophoresis (CZE) and hyphenated with fibre-based spectrophotometric diode array detection (DAD) was compared with, (i) high performance liquid chromatography (HPLC) method with DAD detection, and (ii) HPLC method with fluorescence detection (FD). These methods were compared through their performance parameters and determined concentrations of QUI in beverages. The concentrations of QUI in two selected bitter drinks determined by the CITP-CZE-DAD method were in a good accordance with the HPLC-DAD and HPLC-FD methods. In addition, the electrophoretic method, as well as the chromatographic methods, was able to separate potential QUI related impurities from the QUI peak. The CITP-CZE-DAD method provided excellent performance parameters that were comparable (precision, accuracy, LOD, robustness) or even better (separation efficiency) than those ones provided by the chromatographic methods. Moreover, the effectivity of the electrophoresis method was higher when considering cost of analysis (equipment, consumption of separation systems), environmental aspects (organicvs. aqueous solvents), on-line sample pretreatment (CITP preconcentration and sample clean-up suitable also for the more complex matrices). Considering these findings, CITP-CZE-DAD was approved as a routine automatized method for the highly reliable quality food control.

Determination of kaempferol in extracts from Lilium candidum L. Liliaceae by means of liquid chromatographyThere is an optimized, validated and implemented method for determination of kaempferol through liquid chromatography in terms of isocratic separation in the proportion: 0.05% phosphoric acid and acetonitril (50:50) v/v. The limits of detection (LOD) and quantification (LOQ) were determined. The content of kaempferol in samples from Lilium candidum L. with the use of different concentrations of extract agent and after releasing kaempferol from dermal semisolid medicaments was investigated. The samples were prepared by various producers. The results obtained proved that the implemented method shows good validated parameters and is favourable for determination of kaempferol in samples from Lilium candidum L. It was kaempferol that evaluated best from the samples that were prepared by extraction of 80% ethanol. The contents in the samples were determined using the method, after releasing kaempferol from dermal semisolid medicaments.

Comparison of different computational methods for water structure optimisationWe have compared several computational techniques with the aim to compute the radial distribution function (RDF) as a good characterization of water structure. In particular, we have used molecular mechanic (AMBER99), semi-empirical (AM1, PM3, PM6) and ab initio (DFT) technique. It has been shown that molecular mechanic gives very poor results in the case of water RDF. Ab initio techniques which are in general accepted as very exact methods, in the case of water underestimate intermolecular interaction. Unexpectedly, the semi-empirical method with PM6 parameterisation gives the best results in comparison with RDF measured by X-ray scattering experiment.

Geography and Social Sciences in Transdisciplinary Science
The subject of the paper is the status and relationships of geography, especially human geography, with the social sciences on the background of the evolution of science from multidisciplinary to transdisciplinary. Progressive hybridization of disciplines and specialties upset the identity of geography in modern science, but geography (human geography), as she was, so it is hardly accepted as a social science among scientists. An important role is played by the traditional assignment of the entire geography to natural sciences and greater isolation of human geography in flows of knowledge within the social sciences. The article presents the specificities of the social sciences in the classification of the sciences, the impact of social sciences on past development of geography and contemporary impact of geography on spatial turn in the social sciences.

Contemporary Climate Changes in the High Mountain Part of the Tatras
The purpose of this study was to determine the contemporary changes of precipitation and nival conditions in the high-mountain area of Tatras. Main features of thermal climate changes are the background of this investigation. The study makes use of the daily data from the weather station on Kasprowy Wierch Mt. from the years 1966-2006. Various climate characteristics were considered. The increase of the air temperature is not accompanied by significant changes in precipitation conditions. The signs of the more continentality climate features are also visible. The warming and a slight decrease in precipitation and the evolution of circulation conditions significantly influence the length of the period with the snow cover and not significantly its depth.

Annual and Daily Changes of Thunderstorms in Temperate Climate in London, Warsaw and Moscow
The aim of the study is to show and compare variation of the annual and daily course of thunderstorms in selected European cities in 2005-2009. Data on thunderstorms originate from dispatches METAR for three airport stations: London Gatwick, Warsaw Okęcie and Moscow Sheremetyevo. These cities represent the various types of climate: warm temperate marine, transitional and continental. Thunderstorms mostly occurred in Warsaw - 207 (Moscow - 174, London - 71). The maximum of thunderstorms frequency, in the yearly course, in all towns occurred in July (Warsaw - 11,8; Moscow - 13,4; London - 5,0). Thunderstorms predominantly started at 13:30 in London, 17:00 in Warsaw, 18:00 in Moscow (13:30 means period 13:01-13:30, 17:00 means period 16:31-17:00 etc.). Thunderstorms most often ended at 13:30 in London, 17:00 in Warsaw, 20:30 in Moscow. There were dominated, at all stations, brief thunderstorms, which lasted for 30 minutes. The longest thunderstorm remained 9 hours (Warsaw), 5,5 (Moscow), 4,5 (London).

Potential and Conditions for the Development of the Creative Sector in Warsaw
The creative sector has become an important source used to create competitive advantages of the cities. The importance of creative industries in urban development was spotted more than a decade ago. Creative capital is perceived as an impulse and engine of urban changes, a source of new advantages and attractions. Some point out that it mainly develops in big cities, where the authorities deliberately implement measures aimed at supporting and attracting creative entities. The purpose of this study is to present the condition of the creative sector in Warsaw and the way its functioning is perceived by its representatives. It also discusses the support of city authorities for the development of the creative sector.

The Potential of Fuzzy Logic for Quantitative Land Cover Change Analysis Basing on Historical Topographic Maps
This paper describes an approach that allows to reduce error propagation when comparing historical topographic maps. By linking the fuzzy set theory with simple map algebra and Kappa statistics, the uncertainty resulting from dissimilar quality of the maps can at least be partly eliminated and a distinction between ‘true’ and ‘false’ land cover changes can be made.

On Computational Power of Partially Blind Automata
In this paper we deal with 1-way multihead finite automata, in which the symbol under only one head (called read head) controls its move and other heads cannot distinguish the input symbols, they can only distinguish the end-marker from the other input symbols and they are called the blind head. We call such automaton a partially blind multihead automaton. We prove that partially blind k + 1-head finite automata are more powerful than such k-head finite automata. We show also that nondeterministic partially blind k-head finite automata languages are not closed under iteration and intersection for any k ≥ 2, and moreover, deterministic partially blind k head finite automata languages are not closed under intersection, union, complementation and reversal for any k ≥ 2. Finally we prove that deterministic partially blind k-head finite automata with endmarker are more powerful that such automata without endmarker for each k ≥ 4.

Minimize Traffic Congestion: An Application of Maximum Flow in Dynamic NetworksAn important characteristic of a network is its capacity to carry flow. What, given capacities on the arcs, is the maximum flow that can be sent between any two nodes? The dynamic version of the maximum flow problem on networks that generalizes the well-known static one. This basic combinatorial optimization problem has a large implementation for many practical problems. Traffic congestion is a consequence of the nature of supply and demand: capacity is time consuming and costly to build and is fixed for long time periods, demand fluctuates over time, and transport services cannot be stored to smooth imbalances between capacity and demand. In this paper, I tried to solve the traffic congestion problem i.e. Maximum flow of goods in a dynamic network with the help of a Lingo Model. The same can be generalized for the large product if the software supports the systems.

La relation dans tous ses états. Les objets flottants comme révélateurs de complexité et facteurs de changement
Authors: Caillé Philippe 
Published: August 2012

La relation humaine qui se veut pérenne exige que ses participants sortent du cycle du troc pour entrer dans celui du don. Ce changement fondamental implique que, lorsqu’on croit donner à l’autre ou aux autres, on donne en fait à la relation, à sa structure autoréférentielle qu’on appellera le « tiers » de la relation ou son « absolu relationnel ». De ce fait, la demande d’aide est généralement conditionnée par la perte de contact des intéressés avec le « tiers » qui fondait leur relation, les reconduisant à une situation de troc précaire et chargée de conflits. Pour répondre au besoin du système demandeur de retrouver un « tiers » fiable et évolutif, l’intervenant devra respecter l’intégrité du système demandeur en créant rapidement l’espace de travail partagé qu’est l’« espace intermédiaire » et en tentant d’entraîner le système demandeur à une découverte de son « tiers » par l’usage des « objets flottants », révélateurs de complexité relationnelle. Cette expérience amènera le système demandeur de retrouver un « tiers » authentique et par là même une nouvelle autonomie, mettant ainsi fin à la mission de l’intervenant.
Thérapie de couple et objets flottants
Authors: Rey Yveline 
Published: August 2012

En thérapie de couple, deux moments sont particulièrement délicats et sensibles : celui de la rencontre et celui de la séparation. L’auteur propose d’aborder plus précisément ces deux étapes à travers la modélisation des objets flottants. Les techniques les plus adaptées comme le panier à problèmes, le blason puis le conte systémique seront illustrées par des situations cliniques qui donnent un nouvel éclairage, aussi bien de la relation de couple que de la relation avec les couples ; elles mettent également en évidence la pertinence et l’élégance de ces méthodes d’entretien systémique dans la rencontre thérapeutique.

La « Carte géo-affective » et l'évaluation en « Trio ». Outils inspirés du psychodrame en formation systémique
Authors: Barreau Catherine , Filleul Bernard , Nève-Hanquet Chantal 
Published: August 2012

Cet article présente deux « outils » qui s’apparentent au psychodrame, soit par des approches spécifiques (doublage), soit par l’engagement corporel. La « Carte géo-affective » peut être utilisée comme exercice de mise en train et favorise la présentation entre les membres d’un groupe avec créativité et spontanéité. Elle révèle les appartenances multiples et les définitions relationnelles qui existent entre les membres du groupe. Le dispositif du « Trio » est proposé pour une évaluation formative et se construit sur trois rôles : le « Donneur », le « Receveur » et le « Doubleur ». Il favorise l’engagement personnel des étudiants qui seront alors les acteurs d’une évaluation qualitative. La mise en jeu, l’aspect ludique des deux exercices présentés activent l’audace et la créativité dont feront preuve les futurs thérapeutes.
Cibler l'accompagnement de la parentalité avec le MOSIPE, Modèle d'Observation Systémique des Interactions Parents-Enfants
Authors: Bopp-Limoge Christiane 
Published: August 2012

Cet article décrit le MOSIPE, Modèle d’Observation Systémique des Interactions Parents-Enfants, conçu pour flexibiliser les systèmes familiaux ; il facilite la traversée des cycles de vie, et prévient l’enlisement des crises grâce à trois items transversaux : l’existence de Plaisir partagé dans les relations entre les membres du système, qui dynamise la cohésion du système tout en lui procurant de la flexibilité ; la possibilité de recevoir de l’Estime de soi dans ces relations, ce qui permet d’une part de se différencier de l’autre, et en même temps d’accepter que l’autre se différencie par rapport à soi sans se sentir en danger ; la capacité de percevoir et tenir compte des Besoins de l’autre, qui atteste à la fois des capacités de différenciation des membres du système, et de leur solidarité. Ce modèle peut être également utilisé pour flexibiliser d’autres systèmes humains.
L'âge virtuel de compétence
Authors: Berlioz-Ruffiot Anne 
Published: August 2012

L’« âge virtuel de compétence » est un outil métaphorique élaboré dans le but de faciliter le travail avec l’enfant en difficulté à l’école et sa famille. Lorsqu’une tâche est prescrite à l’enfant, elle donne lieu à un recueil d’informations sur la façon dont il s’en acquitte (sourires, grimaces, nombre de réussites...). On peut alors calculer l’âge virtuel de l’enfant par rapport à cette compétence, qui consiste à lui attribuer un pourcentage de son âge réel correspondant au pourcentage de réussite ou de réalisation de la-dite tâche. Cet outil présente deux avantages : il permet un feed-back clair et immédiatement appréhendable par les enfants comme par leurs parents et il constitue, à lui seul, un recadrage efficace de la difficulté de l’enfant comme une étape du « grandir ».

Abstract
Cigarette smoke (CS), the major cause of chronic obstructive pulmonary disease, contains a variety of oxidative components that were implicated in the regulation of Src homology domain 2-containing protein tyrosine phosphatase 2 (Shp2) activity. However, the contribution of Shp2 enzyme to chronic obstructive pulmonary disease pathogenesis remains unclear. We investigated the role of Shp2 enzyme in blockading CS-induced pulmonary inflammation. Shp2 levels were assessed in vivo and in vitro. Mice (C57BL/6) or pulmonary epithelial cells (NCI-H292) were exposed to CS or cigarette smoke extract (CSE) to induce acute injury and inflammation. Lungs of smoking mice showed increased levels of Shp2, compared with those of controls. Treatment of lung epithelial cells with CSE showed elevated levels of Shp2 associated with the increased release of IL-8. Selective inhibition or knockdown of Shp2 resulted in decreased IL-8 release in response to CSE treatment in pulmonary epithelial cells. In comparison with CS-exposed wild-type mice, selective inhibition or conditional knockout of Shp2 in lung epithelia reduced IL-8 release and pulmonary inflammation in CS-exposed mice. In vitro biochemical data correlate CSE-mediated IL-8 release with Shp2-regulated epidermal growth factor receptor/Grb-2–associated binders/MAPK signaling. Our data suggest an important role for Shp2 in the pathological alteration associated with CS-mediated inflammation. Shp2 may be a potential target for therapeutic intervention for inflammation in CS-induced pulmonary diseases.
Current therapy and recent advances in the management of retinoblastoma

Published: August 2012

AbstractRetinoblastoma is the most common intraocular malignancy in children. The survival of retinoblastoma patients and visual outcome has improved dramatically in the developed world. This can be attributed to early tumor recognition and advances in the management of retinoblastoma. Chemoreduction followed by adjuvant consolidative treatment has replaced external beam radiotherapy as the primary modality of treatment for intraocular retinoblastoma. Further, histopathological high-risk factors have been identified in enucleated eyes, allowing use of prophylactic chemotherapy to take care of possible micrometastasis. The survival in case of extraocular retinoblastoma is still low, and the reported survival rate ranges between 50% and 70%. In developing countries, the overall survival of retinoblastoma patients remains low, primarily due to a delayed presentation, resulting in larger proportions of extraocular disease compared with the developed world, where majority of the disease is intraocular. Greater efforts need to be directed toward early tumor recognition in order to improve the survival of retinoblastoma patients in the developing world. In this article, we provide an overview of the current clinical management of retinoblastoma.
