Novel Cu and Cu2In/aluminosilicate type catalysts for the reduction of biomass-derived volatile fatty acids to alcohols
Authors: Harnos Szabolcs , Onyestyák György , Barthos Róbert , Štolcová Magdalena , Kaszonyi Alexander , Valyon József 
Published: September 2012

Abstract
This work relates to the consecutive reduction of short chain carboxylic acids (volatile fatty acids, VFAs) to alcohols as main products. Acetic acid (AA) was used as a reactant to model the VFAs that can be produced by either thermochemical or biological biomass degradation. The amorphised zeolite supported copper catalysts (Cu/SiAl), especially the In-modified CuIn/SiAl catalysts, showed high hydroconversion activity and selectivity for alcohol, ester and aldehyde. Catalysts containing dispersed copper particles in amorphous aluminosilicate were obtained by dehydrating and H2-reducing Cu-forms of low-silica synthetic zeolites (A, X, P). The activity of the highly destructed Cu-aluminosilicates was found to depend on the structure of the zeolite precursor. The formation of ethyl acetate could be suppressed by adding water to the AA feed and by modifying the catalyst, e.g. by In2O3 additive. In the catalysts modified by In2O3 additive formation of copper-indium alloy phase (Cu2In intermetallic compound) was detected resulting in a different selectivity than the one recorded for the Cu/SiAl.
Application of multivariate curve resolution-alternating least squares (MCR-ALS) for resolving pyrogallol autoxidation in weakly alkaline aqueous solutions

Published: September 2012

Abstract
Multivariate curve resolution — alternating least squares (MCR-ALS) has been applied to data collected from UV/Vis spectrophotometric analysis of the autoxidation process of pyrogallol in weakly alkaline aqueous solutions. The MCR-ALS analysis was able to explain the autoxidation kinetics of pyrogallol at pH 7.4 and 8.0, allowing deduction of the pure spectra and concentration changes of different species present throughout the entire process. The autoxidation process at pH 7.4 was found to follow a first-order reaction model, with formation of purpurogallin as the sole and terminal product. Changing the pH to 8.0 not only accelerated autoxidation of pyrogallol to purpurogallin but also introduced a further autoxidation of purpurogallin. At pH 8.0 the process fits a model of two consecutive first-order reactions. The first step is formation of purpurogallin, which reacts in a further autoxidation to form a yellow colored substance, most probably purpurogallin polymer.
Chitosan/anionic surfactant microparticles synthesized by high pressure spraying method for removal of phenolic pollutants

Published: September 2012

Abstract
Biopolymeric microparticles were prepared by rapid expansion of high pressure CO2-chitosan (Chi) solution in sodium bis-(2-ethyl hexyl) sulfosuccinate (AOT) solution. At pressures higher than 2 MPa, ultrafine particles were formed while under this value, wires were obtained. The formation of Chi/AOT complex was confirmed by Fourier Transform Infrared (FTIR) Spectroscopy, whereas scanning electron microscopy was used to characterize the morphology, size and shape of the particles. The FTIR spectrum proved the interaction between the sulfonate groups of AOT and the amino groups of Chi. Microparticles are quasi-spherical in wet conditions and irregular after freeze drying, presenting a rough surface with many pores. Lyophilized hydrophobic microparticles were used to remove phenol and o-cresol from aqueous solution, and the adsorption process showed a maximum efficiency in the 7–8 pH range. The uptake of phenol and o-cresol increased with the amount of particles and decreased with increasing the pollutant concentration. The adsorption occurred rapidly in the first 60–120 minutes, and leveled off thereafter.
On the influence of Greenland outlet glacier bed topography on results from dynamic ice-sheet models

Published: September 2012

AbstractPrediction of future changes in dynamics of the Earth’s ice sheets, mass loss and resultant contribution to sea-level rise are the main objectives of ice-sheet modeling. Mass transfer from ice sheet to ocean is, in large part, through outlet glaciers. Subglacial topography plays an important role in ice dynamics; however, trough systems have not been included in bed digital elevation models (DEMS) used in modeling, because their size is close to the model resolution. Using recently collected CReSIS MCoRDs data of subglacial topography and an algorithm that allows topographically and morphologically correct integration of troughs and trough systems at any modeling scale (5 km resolution for SeaRISE), an improved Greenland bed DEM was developed that includes Jakobshavn Isbræ, Helheim, Kangerdlussuaq and Petermann glaciers (JakHelKanPet DEM). Contrasting the different responses of two Greenland ice-sheet models (UMISM and SICOPOLIS) to the more accurately represented bed shows significant differences in modeled surface velocity, basal water production and ice thickness. Consequently, modeled ice volumes for the Greenland ice sheet are significantly smaller using the JakHelKanPet DEM, and volume losses larger. More generally, the study demonstrates the role of spatial modeling of data specifically as input for dynamic ice-sheet models in assessments of future sea-level rise.
Effective or Appropriated Federalism?
Authors: Nurieva Elvira 
Published: September 2012

Résumé Un fédéralisme effectif se caractérise par l’autonomie politique, juridique et administrative des entités constituantes, par des subventions financières attribuées aux différents ordres de gouvernement et par une instance représentant les intérêts régionaux au niveau fédéral (Ronald Watts). De jure, la constitution de la fédération de Russie considère deux niveaux de gouvernement, précise les compétences (fédérales, partagées et résiduelles), et garantit la représentation régionale dans la seconde chambre, le Conseil de la Fédération. Cependant, de facto, le fédéralisme russe, en particulier après les réformes fédérales du président Vladimir Poutine (2000-2004), représente une forme de gouvernance loin d’être aussi « effective ». Par exemple, la nouvelle organisation du Conseil de la Fédération a substantiellement affaibli cette institution, et l’a transformée en un organe plutôt cérémoniel. La désignation des gouverneurs de région par le président russe a privé les entités constituantes de leur autonomie politique. L’étude de la situation troublée du peuple Mari dans la république de Mari El, en particulier durant la présidence continue de Leonid Markelov, nourrit ce débat avec les constatations et les mises en garde des principales organisations des droits de l’homme (Minority Rights Group International, International Helsinki Federation for Human Rights, Moscow Helsinki Group).
Les enjeux de la prévention
Authors: Forette Françoise 
Published: September 2012

La révolution de la longévité est un privilège de nos nations développées à la condition que la population vieillisse en bonne santé, active et pleinement intégrée à la société. C’est dire la nécessité absolue de la prévention qui a trois cibles : les maladies liées à l’âge, la fragilité et l’inactivité. Les acteurs prioritaires en sont l’école, le milieu professionnel, les institutions de prévoyance et de retraite et le médecin généraliste. Ainsi, l’éducation, la prévention et l’intégration sociale et professionnelle feront du vieillissement une nouvelle aventure du vivant.
Résultats d'un programme de prévention bucco-dentaire
Authors: Birou Gérard 
Published: September 2012

Le service prévention santé, l’échelon national du contrôle médical de la Caisse centrale de la mutualité sociale agricole (CCMSA) et les chirurgiens-dentistes conseils du réseau ont mis en place un programme de prévention bucco-dentaire axé sur certains âges ou populations à risque. L’action destinée aux bénéficiaires de 65 ans de la mutualité sociale agricole (MSA) a pour objet de leur proposer un bilan bucco-dentaire gratuit. Il s’agit pour le praticien de réaliser un état des lieux des besoins en soins et de donner des conseils personnalisés. La méthodologie de l’action permet également d’évaluer le pourcentage de personnes qui n’ont pas participé à l’examen de prévention et qui ne sont pas suivies habituellement sur le plan dentaire. L’analyse des résultats par catégories socioprofessionnelles traduit des inégalités de l’état bucco-dentaire, des comportements et des recours aux soins.

L’année 2011 est une année d’évolution pour les maisons pour l’autonomie et l’intégration des malades Alzheimer (Maia) . Ces dispositifs innovants qui visent à simplifier le parcours des personnes en perte d’autonomie entrent dans les textes réglementaires. Inscrit dans la loi de finances de la sécurité sociale 2011, le cahier des charges national approuvé par décret vient donner les bases légales et réglementaires pour lancer la généralisation du dispositif. Maia est une méthode pour conduire des porteurs identifiés de la coordination (réseaux de santé, centres locaux d’information et de coordination (Clic), conseils généraux...) vers une dynamique partenariale innovante : l’intégration des services d’aide de soins et d’accompagnement en un même dispositif.
Les Agamas : des livres saints canoniques
Authors: Fuller Chris 
Published: September 2012

Les Agamas sont des textes sanscrits qui régissent le rituel hindou des temples de Shiva. Dans les écoles religieuses, les prêtres en mémorisent par cœur des passages entiers, mais n’apprennent pas à exécuter les rituels conformément aux règles agamiques, comme les réformistes estiment qu’ils devraient le faire. Or, une telle exigence renvoie à une conception moderne des Agamas comme livres saints canoniques, qui a été favorisée par l’impression, la publication et la révision de copies manuscrites de ces textes. L’Institut français de Pondichéry a joué un rôle important dans ce processus en faisant paraître des versions autorisées de textes agamiques. La primauté de l’oralité reste valorisée et, bien qu’ils soient désormais des « livres saints », les Agamas ne sont pas des « livres-objets » sacrés comme il en existe dans d’autres religions.

Cross-linking for the Management of Pellucid Marginal Degeneration in a Case of an Unsuccessful Implantation of Intracorneal Ring Segments
Authors: Tuffaha Bader Tarek , Piñero David P 
Published: September 2012

ABSTRACT
We present a case of progressive pellucid marginal degeneration (PMD) treated with cross-linking (CXL) after a previous unsuccessful implantation of intracorneal ring segments. One year after surgery, an increase in the corneal biomechanical properties accompanied by an improvement in corrected visual acuity and a decrease in the magnitude of corneal coma-like aberrations was observed. However, the magnitude of the refractive cylinder and keratometry increased whereas the internal astigmatism was reduced by 3.93 D. CXL in a cornea with a progressive PMD seems to induce not only changes in the anterior corneal surface, but also in the posterior corneal surface.

Published: September 2012

ABSTRACT
Corneal cross-linking has proven safety and efficacy in arresting the progression of keratoconus. Its use has been extended to resolution of corneal edema. We present a case report and review of literature on the treatment of corneal edema using corneal cross-linking. Corneal cross-linking seems to be an effective method in reducing corneal edema at least as a temporary measure till definitive solution, such as penetrating keratoplasty (PKP) or Descemet's stripping automated endothelial keratoplasty (DASEK) is preformed.

Fixed Dilated Pupilla as a Common Complication of Deep Anterior Lamellar Keratoplasty Complicated with Descemet Membrane Perforation
Authors: Bozkurt Kansu Tahir , Acar Banu Torun , Acar Suphi 
Published: September 2012

Purpose. To report 8 cases of fixed dilated pupilla (FDP) (Urrets-Zavalia syndrome) following deep anterior lamellar keratoplasty (DALK) with Descemet membrane (DM) perforation and change of management to avoid FDP. Methods. Retrospective analysis of 106 eyes of 94 patients who underwent DALK for various diagnoses was performed. Intraoperative and postoperative details of eyes that developed DM detachment, FDP, as well as change of management to prevent rise of intraocular pressure (IOP) (as a common trait of these eyes) were evaluated. Results. Descemet membrane perforation developed in 17 (16%) eyes. Fixed dilated pupilla was diagnosed in 8 (7.5%) eyes. Seven of the eyes with FDP experienced DM perforation and air bubble was left in anterior chamber (AC) to tamponade DM perforation at the end of the surgeries. Five eyes developed FDP in the early postoperative period and the remaining 2 eyes, which were diagnosed as double AC and managed by repeated air injections, developed FDP in the third postoperative week. The last patient who experienced intense postoperative inflammation had a fixed dilated pupil in the third postoperative week. Conclusions. Fixed dilated pupilla is an uncommon but well-known complication of keratoplasty. The exact mechanism remains unknown but postoperative high IOP seems to be an important risk factor following complicated DALK. Rise in IOP during the management of complications following DALK related to DM was found to be important in the development of FDP in this series.
Droit et pédagogie : définition d’un domaine de recherche
Authors: Emond Louis 
Published: September 2012

Dans l’article qui suit, l’auteur définit ce que pourrait être le domaine de recherche « droit et pédagogie » en faisant l’inventaire des publications pouvant s’y intégrer et servir de fondements. Trois grandes approches orientent la démarche d’exploration de ce domaine de recherche : le droit de la pédagogie, le droit comme pédagogie et le droit dans la pédagogie. Chacune permet d’explorer une autre dimension de la relation qu’entretiennent, ou pourraient entretenir, la justice et l’école, deux institutions étatiques chargées, entre autres, de réguler les comportements des individus. L’article se termine par une analyse critique du livre de Violaine Lemay, Évaluation scolaire et justice sociale, seul ouvrage québécois à se réclamer ouvertement du droit et de la pédagogie.
Students’ Participation in Learning Activities and Innovative Approaches to Increase Students’ Participation at Higher Level
Authors: Rasul Saima , Bukhshl Qadir 
Published: September 2012

Learning is acquiring new or modifying existing knowledge, behaviors, skills, values, or preferences and may involve synthesizing different types of information. It provides students with opportunities to learn and practice new knowledge and strategies, to explain their reasoning, and to examine their thinking processes and recognize the need to revise thinking. The study analyzed the students’ participation in learning activities and innovative approaches to increase students’ participation at higher level. To achieve the purpose of study two questionnaires were designed as research tool separately for teachers and students. The questionnaire was administered to 200 students and 100 teachers of The Islamia University of Bahawalpur (Pakistan) and Bahauddin Zakriya University of Multan (Pakistan). It was strongly recommended that learning activities should be according to students’ level. Students should be motivated and encourage by the teachers to participate in learning activities. Less emphasis should be placed on transmitting information and more on developing student’s skills. New innovative approaches should be used to increase students’ participation in learning activities. Keywords - Students’ participation, learning activities, innovative, approaches, higher level
Awareness of Internet Plagiarism Among The Secondary School Students in Gombak, Selangor, Malaysia
Authors: Hasan Rajiah 
Published: September 2012

Plagiarism has long been a problem in educational setting and with the advent of the Internet revolution and highly user-friendly word processing software, plagiarism has become a widespread phenomenon. Internet exposes students to a multitude of resources in their learning process. Ironically, these phenomena also brought tremendous opportunities for the plagiarism on cyberspace to take place. Students freely copy and paste informations directly from Internet in the assignments and claimed the works as theirs. Very limited research had been done and there are no study had been conducted in secondary school students in Malaysia. This study aims to investigate the reasons behind the increased phenomena of the internet plagiarism among students in one of the secondary schools in Gombak, Selangor, Malaysia. Data collection and the subsequent analyses were guided by qualitative research methods with the theoretical backdrop of Rogers Model of Innovation-Decision Process (Rogers, 1962). In this research, researcher uses the term “awareness of the internet plagiarism” as the “innovation”. 4 themes emerged from this research, namely (1) lack and limited knowledge (2)lack and limited awareness and (3) normal phenomena (4) easy access to Internet. These themes are discussed with reference to the finding of other studies in plagiarism and the implication for the continuum of the education in Malaysia is pointed out. Keywords - internet plagiarism, secondary school student, Gombak, Selangor, Malaysia
‘What Would You Say if You Were Guilty?’ Suspects' Strategies During a Hypothetical Behavior Analysis Interview Concerning a Serious Crime
Authors: Masip Jaume , Herrero Carmen 
Published: September 2012

SummaryPrevious research has shown that the Behavior Analysis Interview (BAI) indicators of guilt or innocence are merely commonsense notions. In this study, we examined whether this would lead suspects of a serious crime to try to manipulate their behavior during a BAI in order to look innocent. A serious crime was described to 74 undergraduates who were asked to imagine that they were guilty or innocent. They then completed a questionnaire about the strategies that they would use during a BAI. Both guilty and innocent suspects were more willing to show the innocence rather than guilt indicators of the BAI. Innocent suspects had a blind faith in the power of innocence to demonstrate that they were not guilty. The general (non‐BAI) strategies coincided with those of previous studies; this indicates that prior findings on strategies can be generalized to serious crimes and that strategies can be examined with uncomplicated procedures such as the one used in this study.

Magnetite/Polypyrrole Hybrid Nanocomposites as a Promising Magnetic Resonance Imaging Contrast Material
Authors: Alves Kleber G. B. , Andrade Cesar A. S. , Campello Sergio L. , de Souza Ricardo E. , de Melo Celso P. 
Published: September 2012

AbstractWe have prepared magnetite nanoparticles (Fe3O4_NPs) almost spherical in shape with average particle size of 10 nm and successfully encapsulated them in an envelope of polypyrrole (PPY) chains via an emulsion polymerization route using sodium dodecyl sulfate as surfactant. The resulting PPY‐coated Fe3O4_NPs (Fe3O4_NPs/PPY) suspensions were stable with particles exhibiting a triangular prismatic morphology and an average diameter below 100 nm. In fact, all colloidal solutions were stable in aqueous media with typical ζ‐surface potential values of −33.9 mV (Fe3O4_NPs) and −20.0 mV (Fe3O4_NPs/PPY). Although X‐ray diffraction studies revealed the presence of a magnetic phase Fe3O4, the identified diffraction peaks are consistent with the presence of a spinel structure of magnetite. A ferromagnetic behavior, such as lower coercive force (Hc= 0.065 T), was observed for all magnetic nanoparticles examined. The1H NMR relaxation timesT1andT2of selected Fe3O4_NPs/PPY samples were also measured and their relaxivitiesr1(1.1 s−1mM−1) andr2(61.9 s−1mM−1) compare favorably to those of contrast agents commercially used in human examinations. We suggest that the present results indicate that these hybrid nanocomposites are promising materials for the development of a platform of specialized contrast agents for1H Magnetic Resonance Imaging. © 2012 Wiley Periodicals, Inc.

AbstractIn this paper, the isolation of dillapiole (1) fromPiper aduncumwas reported as well as the semi‐synthesis of two phenylpropanoid derivatives [di‐hydrodillapiole (2), isodillapiole (3)],viareduction and isomerization reactions. Also, the compounds' molecular properties (structural, electronic, hydrophobic, and steric) were calculated and investigated to establish some preliminary structure–activity relationships (SAR). Compounds were evaluated forin vitroantileishmanial activity and cytotoxic effects on fibroblast cells. Compound1presented inhibitory activity againstLeishmania amazonensis(IC50 = 69.3 µM) andLeishmania brasiliensis(IC50 = 59.4 µM) and induced cytotoxic effects on fibroblast cells mainly in high concentrations. Compounds2(IC50 = 99.9 µM forL. amazonensisand IC50 = 90.5 µM forL. braziliensis) and3(IC50 = 122.9 µM forL. amazonensisand IC50 = 109.8 µM forL. brasiliensis) were less active than dillapiole (1). Regarding the molecular properties, the conformational arrangement of the side chain, electronic features, and the hydrophilic/hydrophobic balance seem to be relevant for explaining the antileishmanial activity of dillapiole and its analogues.
