Published: July 2017

The aim of the study was to evaluate antioxidant activity and total phenolic content of juice from three different types of fruits: elderberry (Sambucus nigra), lingonberry (Vaccinium vitis-idaea) and cornelian cherry (Cornus mas), and their action against adhesion of bacterial strains of Asaia lannensis and Asaia bogorensis isolated from spoiled soft drinks. The antioxidant profiles were determined by total antioxidant capacity (2,2-diphenyl-1-picrylhydrazyl, DPPH), and ferric-reducing antioxidant power (FRAP). Additionally, total polyphenol content (TPC) was investigated. Chemical compositions of juices were tested using the chromatographic techniques: high-performance liquid chromatography (HPLC) and liquid chromatography–mass spectrometry (LC-MS). Adhesion properties of Asaia spp. cells to various abiotic materials were evaluated by luminometry, plate count and fluorescence microscopy. Antioxidant activity of fruit juices expressed as inhibitory concentration (IC50) ranged from 0.042 ± 0.001 (cornelian cherry) to 0.021 ± 0.001 g/mL (elderberry). TPC ranged from 8.02 ± 0.027 (elderberry) to 2.33 ± 0.013 mg/mL (cornelian cherry). Cyanidin-3-sambubioside-5-glucoside, cyanidin-3-glucoside, and cyanidin-3-sambubioside were detected as the major anthocyanins and caffeic, cinnamic, gallic, protocatechuic, and p-coumaric acids as the major phenolic acids. A significant linear correlation was noted between TPC and antioxidant capacity. In the presence of fruit juices a significant decrease of bacterial adhesion from 74% (elderberry) to 67% (lingonberry) was observed. The high phenolic content indicated that these compounds may contribute to the reduction of Asaia spp. adhesion.

Published: July 2017

Hollow halloysite nanotubes have been used as nanocontainers for loading and for the triggered release of calcium hydroxide for paper preservation. A strategy for placing end-stoppers into the tubular nanocontainer is proposed and the sustained release from the cavity is reported. The incorporation of Ca(OH)2 into the nanotube lumen, as demonstrated using transmission electron microscopy (TEM) imaging and Energy Dispersive X-ray (EDX) mapping, retards the carbonatation, delaying the reaction with CO2 gas. This effect can be further controlled by placing the end-stoppers. The obtained material is tested for paper deacidification. We prove that adding halloysite filled with Ca(OH)2 to paper can reduce the impact of acid exposure on both the mechanical performance and pH alteration. The end-stoppers have a double effect: they preserve the calcium hydroxide from carbonation, and they prevent from the formation of highly basic pH and trigger the response to acid exposure minimizing the pH drop-down. These features are promising for a composite nanoadditive in the smart protection of cellulose-based materials.
Phonon Transport through Nanoscale Contact in Tip-Based Thermal Analysis of Nanomaterials
Authors: Dulhani Jay , Lee Bong
Published: July 2017

Nanomaterials have been actively employed in various applications for energy and sustainability, such as biosensing, gas sensing, solar thermal energy conversion, passive radiative cooling, etc. Understanding thermal transports inside such nanomaterials is crucial for optimizing their performance for different applications. In order to probe the thermal transport inside nanomaterials or nanostructures, tip-based nanoscale thermometry has often been employed. It has been well known that phonon transport in nanometer scale is fundamentally different from that occurred in macroscale. Therefore, Fourier’s law that relies on the diffusion approximation is not ideally suitable for describing the phonon transport occurred in nanostructures and/or through nanoscale contact. In the present study, the gray Boltzmann transport equation (BTE) is numerically solved using finite volume method. Based on the gray BTE, phonon transport through the constriction formed by a probe itself as well as the nanoscale contact between the probe tip and the specimen is investigated. The interaction of a probe and a specimen (i.e., treated as a substrate) is explored qualitatively by analyzing the temperature variation in the tip-substrate configuration. Besides, each contribution of a probe tip, tip-substrate interface, and a substrate to the thermal resistance are analyzed for wide ranges of the constriction ratio of the probe.

Published: July 2017

PbS colloidal quantum dots (CQDs) solar cells have already demonstrated very impressive advances in recent years due to the development of many different techniques to tailor the interface morphology and compactness in PbS CQDs thin film. Here, n-hexane, n-octane, n-heptane, isooctane and toluene or their hybrids are for the first time introduced as solvent for comparison of the dispersion of PbS CQDs. PbS CQDs solar cells with the configuration of PbS/TiO2 heterojunction are then fabricated by using different CQDs solution under ambient conditions. The performances of the PbS CQDs solar cells are found to be tuned by changing solvent and its content in the PbS CQDs solution. The best device could show a power conversion efficiency (PCE) of 7.64% under AM 1.5 G illumination at 100 mW cm−2 in a n-octane/isooctane (95%/5% v/v) hybrid solvent scheme, which shows a ~15% improvement compared to the control devices. These results offer important insight into the solvent engineering of high-performance PbS CQDs solar cells.
Automated Water Quality Survey and Evaluation Using an IoT Platform with Mobile Sensor Nodes
Authors: Li Teng , Xia Min , Chen Jiahong , Zhao Yuanjie , De Silva Clarence
Published: July 2017

An Internet of Things (IoT) platform with capabilities of sensing, data processing, and wireless communication has been deployed to support remote aquatic environmental monitoring. In this paper, the design and development of an IoT platform with multiple Mobile Sensor Nodes (MSN) for the spatiotemporal quality evaluation of surface water is presented. A survey planner is proposed to distribute the Sampling Locations of Interest (SLoIs) over the study area and generate paths for MSNs to visit the SLoIs, given the limited energy and time budgets. The SLoIs are chosen based on a cellular decomposition that is composed of uniform hexagonal cells. They are visited by the MSNs along a path ring generated by a planning approach that uses a spanning tree. For quality evaluation, an Online Water Quality Index (OLWQI) is developed to interpret the large quantities of online measurements. The index formulations are modified by a state-of-the-art index, the CCME WQI, which has been developed by the Canadian Council of Ministers of Environment (CCME) for off-line indexing. The proposed index has demonstrated effective and reliable performance in online indexing a large volume of measurements of water quality parameters. The IoT platform is deployed in the field, and its performance is demonstrated and discussed in this paper.
Yield Perceptions, Determinants and Adoption Impact of on Farm Varietal Mixtures for Common Bean and Banana in Uganda

Published: July 2017

Crop variety mixtures (different varieties of a crop grown together in a single plot) have been successfully deployed in pathogen and pest management for several crops including wheat, common bean and rice. Despite the available evidence, promotion of this approach has remained limited in many countries, including Uganda. The factors that influence farmers’ adoption of varietal mixtures for common bean and banana were assessed, as well as the perceptions of farmers on the effects of mixtures on yields, through household surveys and statistical modelling. A three-year yield increase in both common bean and banana varietal mixtures in farmer fields, of 5.2% and 28.6%, respectively, is realized using robust OLS estimates. The study reveals that accessing knowledge on the importance of crop varietal mixtures and the skills relating to the approach are crucial for their adoption. Location of the farm significantly determined the perceived yield change, which calls for more research into mixtures’ suitability under particular contexts in respect to compatibility of genotypes, management practices and appropriate acreage for maximum impact. The positive effects of mixtures on yields make it an effective bioeconomy strategy. Policies that minimize the adoption barriers could improve the adoption of crop varietal mixtures on a wider scale.
La genèse du droit des aquifères transfrontières, un feuilleton familial complexe (partie 1)
Authors: Sohnle Jochen
Published: July 2017

This is a commentary of the Draft articles of the International Law Commission on the law of transfrontier aquifers of 2008 in the light of the latest developments (signature of the Agreement on Guaraní aquifer in August 2010, resumption of the draft by the 6th Commission of the United Nations General Assembly in November 2011). This commentary shows in particular that the Draft is not merely an adjunction to the 1997 Convention on International Waterways but an autonomous text strongly influenced by the International law on Shared Natural Resources. This autonomy appears mainly through its proper scope and the setting of material and procedural principles it contains.
The legal framework of cooperation for protection of marine biodiversity in the Black Sea
Authors: Oral Nilüfer
Published: July 2017

La mer Noire, riche en biodiversité dans les années 1990, a subi une perte importante en biodiversité. En 1992, sous les auspices du Programme des mers régionales du PNUE, un programme concernant la mer Noire a été adopté. Malgré des besoins précis révélés par des études scientifiques terminées en 1990, le Protocole sur la biodiversité et la conservation du paysage de la mer Noire ne fut adopté qu’en 2002 et n’est toujours pas entré en application en 2012. Cependant, quand le Protocole entrera en vigueur, il fournira la base légale nécessaire et les instruments de gestion appropriés sont développés depuis 1992. Le présent article fournit une analyse juridique détaillée du Protocole.
Après Durban, quelle structuration juridique pour un nouvel accord international sur le climat ?
Authors: Maljean-Dubois Sandrine , Wemaëre Matthieu
Published: July 2017

Le Protocole de Kyoto n’impose pas aux Etats parties d’obligations chiffrées de réduction des émissions au-delà d’une première période d’engagement prenant fin en 2012. La forme et le contenu des engagements pour une deuxième période d’engagement restaient donc entièrement à définir. Les négociations du «post-2012 » ont démarré dès 2005, dès l’entrée en vigueur du Protocole. En 2007, les Parties ont ouvert en parallèle une deuxième voie de négociation, cette fois dans le cadre de la Convention, pour préparer un accord international plus global, amenant tous les grands pays émetteurs à réduire leurs émissions de gaz à effet de serre. Cet accord devait pouvoir être en vigueur en 2013, à l’issue de la première période d’engagement du Protocole. Or, ni la Conférence de Copenhague en 2009, ni la Conférence de Cancun en 2010, n’ont représenté l’aboutissement des négociations. Elles n’ont pas tranché les questions délicates que sont le sort du Protocole de Kyoto, la forme juridique et l’architecture du futur régime post-2012, qui ont été au centre de la Conférence de Durban. Cette conférence y a apporté une réponse en forme de compromis. La décision a été prise de continuer le Protocole pour une deuxième période, mais également de lancer les négociations pour un nouveau régime, plus inclusif et plus ambitieux, qui devrait être en place à partir de 2020.
Normalisation et certification dans le photovoltaïque : perspectives juridiques
Authors: Boy Laurence
Published: July 2017

In France, as elsewhere, the development of renewable energies (among which the photovoltaic) relies on a voluntary strategy of aid and promotion through various instruments (research, fiscal policy, legal framing). All these means have been used until 2010 summer, when public authority wished to reduce financing an activity that, according to some people, had become speculative. Being anxious, professionals asked for the maintenance of the fiscal incentives sustaining the industry, for the clarification of the legal and fiscal system applying to solar farms, and for the setting up of controls to avoid spreading frauds. Among these means, normalization and certification play an essential part, often ignored by the doctrine. The benefit of flexible law is essential to all concerned (professionals, insurance and consumers). It should be compared to the risk of seizure of this normative power by the most powerful and the exclusion of small industries from the market, though they were strongly encouraged to make investments in this field.
La genèse du droit des aquifères transfrontières, un feuilleton familial complexe (partie 2)
Authors: Sohnle Jochen
Published: July 2017

La présente étude commente le Projet d’articles de la Commission du droit international sur le droit des aquifères transfrontières de 2008 à la lumière des dernières évolutions (signature de l’Accord sur l’aquifère Guaraní en août 2010, reprise du Projet à la 6e Commission de l’Assemblée générale des Nations Unies en novembre 2011). Ce commentaire démontre notamment que le Projet n’est pas un simple complément à la Convention de 1997 sur les cours d’eau internationaux, mais un texte autonome qui a fortement subi l’influence du droit international des ressources naturelles partagées. Cette autonomie se manifeste notamment à travers un champ d’application qui lui est propre et une articulation particulière de la plupart des principes matériels et procéduraux qu’il contient.
La lente consécration de la nature, sujet de droit : le monde est-il enfin Stone ?
Authors: David Victor
Published: July 2017

Les péripéties judiciaires relatives aux poursuites pénales dont a fait l’objet l’industriel Vale, pour pollution à l’acide sulfurique le 1er avril 2009 du Creek de la Baie Nord en province Sud, ont montré que la protection de l’environnement en Nouvelle-Calédonie n’échappait pas à la conception anthropocentrique qui sépare l’homme et la nature et qui s’est imposée au fil des siècles un peu partout dans le monde. Le droit de l’environnement, qu’il soit international ou national, a longtemps été imprégné de cette tradition anthropocentrique qui refuse de reconnaître des droits intrinsèques à la nature en la soumettant systématiquement à l’homme et à la satisfaction de ses besoins et caprices. Pourtant, une autre approche, fondée sur des relations plus inclusives entre homme et nature, est possible. Lancée par le professeur Christopher Stone aux Etats-Unis en 1971, l’idée de reconnaître des droits légaux à la nature et ses éléments a connu la consécration avec l’adoption de la Constitution de l’Equateur en 2008 qui fait de la Terre Mère, la Pacha Mama, un véritable sujet de droit, doté à l’instar des humains, de droits fondamentaux garantis par la Constitution du pays. L’évolution (ou la révolution ?) semble lancée, la Bolivie a pris des mesures similaires en 2009 et depuis 2010, c’est l’ONU qui proclame que l’harmonie avec la nature doit être recherchée et accompagner le développement des sociétés humaines. Des exemples et pistes qui invitent en Nouvelle-Calédonie à redessiner un droit de l’environnement qui (ré) concilie davantage hommes et nature.
Le régime de la publicité, des enseignes et des préenseignes depuis le décret n° 2012-118 du 30 janvier 2012 ou les contradictions du nouveau droit de l’affichage
Authors: Zavoli Philippe
Published: July 2017

Bien davantage qu’une simple mise en oeuvre de la loi du 12 juillet 2010 et après une gestation mouvementée, le décret du 31 janvier 2012 a procédé à une refonte complète de la partie réglementaire du Code de l’environnement relative au droit de la publicité extérieure. Outre la modification du régime national des dispositifs publicitaires existants et l’encadrement des nouveaux dispositifs tels la publicité numérique et les bâches pouvant accueillir de la publicité, le décret simplifie de manière bienvenue les procédures d’instruction des déclarations et des autorisations préalables. La réforme du régime d’élaboration des règlements locaux de publicité a cependant peu appelé de dispositions règlementaires particulières dans la mesure où la loi de 2010 a principalement renvoyé aux procédures propres au plan local d’urbanisme figurant dans le Code de l’urbanisme. Le décret est entré en vigueur le 1er juillet 2012.
Territory, Sovereignty, and New Statehood in the Middle East and North Africa
Authors: Ahram Ariel I.
Published: July 2017

This article examines the interaction between territory, sovereignty, and statehood in the Middle East and North Africa. Various groups have aspired — and have failed — to become states since the contemporary regional system's inception after World War I. Since the 2011
uprisings, movements claiming territory and sovereignty have emerged or become more viable throughout the region, including the Islamic State in Iraq and al-Sham (ISIS), Rojava, Cyrenaica, Azawad, and the Kurdistan Regional Government. Each poses different challenges to the regional system
and holds out different hopes for rectifying historical missteps in state-building.
Human Rights and Wrongs in Iran's Drug Diplomacy with Europe
Authors: Bjerre Christensen Janne
Published: July 2017

Europe has a strong interest in and a history of assisting Iran in controlling inflows of drugs from Afghanistan. But due to Iran's increasing use of the death penalty in drug trafficking cases, Europe has terminated its cooperation. Based on interviews with Iranian policy-makers and
representatives of both human rights organizations and the United Nations Office on Drugs and Crime (UNODC), this article presents Denmark's withdrawal of drug control funding in 2013 as a case study, analyzing the dilemmas and trajectories of joint Iranian-European drug diplomacy and the
prospects for reengagement following the nuclear agreement.

In 2014 February, the System for High contrast And coronography from R to K at VISual bands (SHARK-VIS) Forerunner, a high contrast experimental imager operating at visible wavelengths, was installed at the Large Binocular Telescope (LBT). Here we report on the first results obtained by recent on-sky tests. These results show the extremely good performance of the LBT Extreme Adaptive Optics (ExAO) system at visible wavelengths, both in terms of spatial resolution and contrast achieved. Similarly to what was done by Amara & Quanz (2012), we used the SHARK-VIS Forerunner data to quantitatively assess the contrast enhancement. This is done by injecting several different synthetic faint objects in the acquired data and applying the angular differential imaging (ADI) technique. A contrast of the order of 5 × 10−5 is obtained at 630 nm for angular separations from the star larger than 100 mas. These results are discussed in light of the future development of SHARK-VIS and compared to those obtained by other high contrast imagers operating at similar wavelengths.
The Presence of Turbulent and Ordered Local Structure within the ICME Shock-sheath and Its Contribution to Forbush Decrease
Authors: Shaikh Zubair , Raghav Anil , Bhaskar Ankush
Published: July 2017

The transient interplanetary disturbances evoke short-time cosmic-ray flux decrease, which is known as Forbush decrease. The traditional model and understanding of Forbush decrease suggest that the sub-structure of an interplanetary counterpart of coronal mass ejection (ICME) independently contributes to cosmic-ray flux decrease. These sub-structures, shock-sheath, and magnetic cloud (MC) manifest as classical two-step Forbush decrease. The recent work by Raghav et al. has shown multi-step decreases and recoveries within the shock-sheath. However, this cannot be explained by the ideal shock-sheath barrier model. Furthermore, they suggested that local structures within the ICME’s sub-structure (MC and shock-sheath) could explain this deviation of the FD profile from the classical FD. Therefore, the present study attempts to investigate the cause of multi-step cosmic-ray flux decrease and respective recovery within the shock-sheath in detail. A 3D-hodogram method is utilized to obtain more details regarding the local structures within the shock-sheath. This method unambiguously suggests the formation of small-scale local structures within the ICME (shock-sheath and even in MC). Moreover, the method could differentiate the turbulent and ordered interplanetary magnetic field (IMF) regions within the sub-structures of ICME. The study explicitly suggests that the turbulent and ordered IMF regions within the shock-sheath do influence cosmic-ray variations differently.
A New Approach to the GeV Flare of PSR B1259-63/LS2883
Authors: Yi Shu-Xu , Cheng K. S.
Published: July 2017

PSR B1259-63/LS2883 is a binary system composed of a pulsar and a Be star. The Be star has an equatorial circumstellar disk (CD). The Fermi satellite discovered unexpected gamma-ray flares around 30 days after the last two periastron passages. The origin of the flares remains puzzling. In this work, we explore the possibility that the GeV flares are consequences of inverse Compton scattering of soft photons by the pulsar wind. The soft photons are from an accretion disk around the pulsar, which is composed of the matter from the CD captured by the pulsar’s gravity at disk-crossing before the periastron. At the other disk-crossing after the periastron, the density of the CD is not high enough, so accretion is prevented by the pulsar wind shock. This model can reproduce the observed spectrum energy distributions and light curves satisfactorily.
Triggering Collapse of the Presolar Dense Cloud Core and Injecting Short-lived Radioisotopes with a Shock Wave. V. Nonisothermal Collapse Regime
Authors: Boss Alan P.
Published: July 2017

Recent meteoritical analyses support an initial abundance of the short-lived radioisotope (SLRI) 60Fe that may be high enough to require nucleosynthesis in a core-collapse supernova, followed by rapid incorporation into primitive meteoritical components, rather than a scenario where such isotopes were inherited from a well-mixed region of a giant molecular cloud polluted by a variety of supernovae remnants and massive star winds. This paper continues to explore the former scenario, by calculating three-dimensional, adaptive mesh refinement, hydrodynamical code (FLASH 2.5) models of the self-gravitational, dynamical collapse of a molecular cloud core that has been struck by a thin shock front with a speed of 40 km s−1, leading to the injection of shock front matter into the collapsing cloud through the formation of Rayleigh–Taylor fingers at the shock–cloud intersection. These models extend the previous work into the nonisothermal collapse regime using a polytropic approximation to represent compressional heating in the optically thick protostar. The models show that the injection efficiencies of shock front materials are enhanced compared to previous models, which were not carried into the nonisothermal regime, and so did not reach such high densities. The new models, combined with the recent estimates of initial 60Fe abundances, imply that the supernova triggering and injection scenario remains a plausible explanation for the origin of the SLRIs involved in the formation of our solar system.
The Effect of Three Different Biomaterials on Proliferation and Viability of Human Dental Pulp Stem Cells (In-vitro Study)
Authors: Mohamed Dalia A. , Abdelfattah Maha I. , Aboulezz Eman H. A.
Published: July 2017

BACKGROUND: Biomaterial cytotoxicity on dental stem cells plays a critical role in managing the regeneration of dental tissue.AIM: The aim of the present study was to evaluate the effect of Nano-hydroxy apatite (NHA), Mineral trioxide aggregate (MTA), and Calcium-enriched mixture (CEM) on the proliferation, and viability of human dental pulp stem cells (hDPSCs) isolated from third molar teeth.METHODS: Cultured DPSCs were characterized and the tested biomaterials were shaped into cylinders then inserted directly on the DPSCs. Proliferation and viability percentage of DPSCs were evaluated at 1, 3, 5, 7, 9, 11, and 14 days of culture.RESULTS: The biomaterials supplemented DPSCs showed a significant initial decrease in cell count and viability percentage at day one. Then, a rise in cell counts and viabilities was noticed after that. There was a decrease in cell counts, and viabilities in the NHA supplemented cells in comparison to other tested biomaterials.CONCLUSIONS: All tested biomaterials maintain the proliferation of DPSCs for different durations. NHA showed less proliferative and more cytotoxic effect than other tested materials.
Genetic Diagnosis of Chromosomal Congenital Anomalies in Albanian Pediatric Patients by Array CGH
Authors: Babameto-Laku Anila , Roko Dorina , Vyshka Gentian
Published: July 2017

AIM: The aim of our study was to identify chromosomal imbalances by whole-genome microarray-based comparative genomic hybridization (array CGH) in DNA samples of children in which karyotype results cannot be obtained. The present paper describes the first Albanian experience of an array CGH application.MATERIAL AND METHODS: The cohort included seven children with developmental delay or intellectual disability, facial dysmorphism and congenital anomalies according to clinical criteria, suggestive of chromosomal anomalies. The age range was from newborn to five years old. The cytogenetic analysis determined by a standard method of G-banding according to the International System for Human Cytogenetic Nomenclature (ISCN 2005) was performed for all our patients, while array CGH was performed on genomic DNA isolated from the blood of 7 cases.RESULTS: Among the seven patients analysed with array CGH, three patients resulted in duplication and one deletion, one patient with a microdeletion and three patients with duplication. Array CGH facilitated the recognition of submicroscopic deletions and duplications as risk factors for genetic diagnosis in all our patients.CONCLUSIONS: Our case series with congenital chromosomal anomalies confirms the high diagnostic value of the method, as suggested by previous studies. The technique must be available also in less developed countries, to significantly improve the genetic diagnosis of paediatric patients with developmental delay or intellectual disability, congenital anomalies and dysmorphic features. The identification of chromosomal abnormalities in these patients and the genetic counselling will provide family members with an explanation for their child’s developmental disability or birth defect, allowing better information about recurrence risks, and permit the anticipation of certain medical problems that require intervention.

O açaí é o fruto proveniente da palmeira tropical Euterpe Oleracea M. que é bastante difundida e cultivada na Amazônia brasileira. A polpa do açaí é extraída utilizando equipamentos adequados com adição de água durante o processamento. Esta polpa é largamente consumida pela população paraense, sendo esta, a principal atividade econômica de muitas famílias ribeirinhas da região. O objetivo do presente estudo foi caracterizar a polpa de açaí em relação à composição nutricional e funcional, com ênfase na quantificação de compostos fenólicos totais, antocianinas totais e da capacidade antioxidante total. A polpa de açaí apresentou valores elevados de umidade (85,36%) e atividade de água (0,996). Esta foi classificada como do tipo A, grossa ou especial de acordo com a legislação vigente e com base no teor de sólidos totais encontrados (14,64%). A polpa possui teor lipídico relativamente elevado, e baixo teor proteico. A polpa de açaí apresentou 346,14 mg de AGE/100g de compostos fenólicos totais, 73,54 mg/100g de antocianinas totais e 17,15 µmol de TE/g para capacidade antioxidante, podendo ser considerada como uma boa fonte de compostos antioxidantes.
AVALIAÇÃO QUÍMICA E FÍSICA DO QUEIJO DE PORCO: UM EMBUTIDO COZIDO PREPARADO COM SUB-PRODUTOS COMESTÍVEIS ORIUNDOS DE ABATE DE SUINOS

Published: July 2017

O queijo de porco é um produto cozido elaborado a partir de subprodutos proveniente do abate suíno. Sabendo-se que o suíno gera em torno de 44% de subprodutos a utilização racional deste material tem importância econômica e ambiental. A composição química, valor energético, nitrito residual, oxidação lipídica e parâmetros físicos (cor e textura) foram avaliadas para contribuir com os órgãos fiscalizadores brasileiros na regulamentação do produto. A composição química apresentou variabilidade quando comparado a outros queijos de porco devido a formulação e qualidade da matéria-prima. O uso de miúdos na formulação proporcionou maiores teores de colesterol, colágeno e ferro em relação a outros embutidos da categoria. Maior parte da proteína é constituída de colágeno, e responsável pelos valores encontrados de força de cisalhamento (7,84 ± 1,68 N). Contém expressiva quantidade de sódio devido à adição de condimentos não ser regulamentada e teores de cálcio próximos a de outros embutidos. Houve predominância de ácidos graxos poli-insaturados (AGPI), e a razão AGPI/ácidos graxos saturados (AGS) foi de 0,51 acima do recomendado que é de 0,45 para AGPI/AGS. O nitrito estava dentro dos limites estabelecidos pela legislação brasileira (89,5 ± 28,7 mg kg-1) e pode ter sido o responsável pela conservação do produto. Sendo assim, baixos níveis de oxidação foram quantificados. Baixos índices de vermelho (a*) ocorreram provavelmente devido à ação do cozimento e formação de metamioglobina que acarreta ao produto uma cor mais amarronzada

A escritora Lygia Bojunga, de forma recorrente, tem recebido a láurea. Sua mais recente obra premiada foi Querida, publicada em 2009 e premiada em 2010.  O presente trabalho busca identificar em que medida a obra Querida (2009) dialoga com o leitor, considerando-o pertencente à faixa etária cuja obra foi premiada, aos adolescentes. De fato, para identificar tais aspectos de diálogo (leitor-livro), este trabalho considerará a literatura como uma representação simbólica e imaginária das relações sociais, amparando-se nos conceitos e discussões da Sociologia da Leitura, bem como, da estética da recepção, a partir daquilo que a obra Querida pressupõe de seu leitor modelo, apontando o que este deve ser capaz de entender para preencher os vazios do texto. Dessa forma, este estudo procura indicar, também, a relevância dos aspectos socioculturais imbricados na construção deste leitor modelo.
Mickey, Zé Colmeia e Cia: vertentes do cinema de animação (1920 – 2015)
Authors: Luiz Fernando
Published: July 2017

ResumoÍndices expressivos de bilheteria atestam que o gênero animação é aclamado por crianças e adolescentes, embora não integre, de maneira efetiva, o cotidiano escolar, que prioriza a leitura do cânone literário a partir de uma proposta metodológica ainda didatizadora, monológica e estruturalista. Os desenhos animados, desse modo, penetrariam nas unidades de ensino como gênero marginal, vivo e incisivo nas falas e comportamentos dos alunos. Tendo em vista esse quadro, a presente pesquisa tem como principal objetivo problematizar as propostas estéticas veiculadas em desenhos tradicionais e contemporâneos, produzidos, divulgados e comercializados em diferentes países. Para tanto, a investigação, fundamentada no dialogismo bakhtiniano, analisou duzentas e quinze produções lançadas ao longo de quase cem anos, comercializadas em DVDs ou disponibilizadas na internet, especificamente no You Tube. Almeja-se, desse modo, a partir dos recursos empregados pelos estúdios na tecitura do texto visual e das múltiplas vozes instauradas ao longo dos desenhos, identificar as propostas artísticas tanto em narrativas mais “formais”, veiculadas entre os anos de 1960 e 1970, quanto nas produções mais “arrojadas”, firmadas após a década de 1990, de natureza polissêmica e emancipatória, marcadas pela metalinguagem, pela polifonia, pela incidência de heróis excêntricos, por anacronismos, pelas inúmeras alusões à cultura pop e, em especial, pela intertextualidade.Palavras-Chave: desenho animado; estética; dialogismo; infância; ideologia.
Dialogismo em textos para crianças: Nícolas e a orquestra da lua cheia
Authors: Galvão Ribeiro Ferreira Eliane Aparecida , Valente Thiago Alves
Published: July 2017

Este artigo analisa as obras Nícolas, escrito por Agnès Laroche, ilustrado por Stéphanie Augusseau, e traduzido por Isabelle Gamin e Rosana de Mont’Alverne Neto, e A orquestra da lua cheia, escrita e ilustrada por Jens Rassmus, com tradução de Sofia Mariutti, a partir da ideia de dialogismo de Bakhtin (1995) e de leitor implícito de Wolfgang Iser (1996). As obras se destacam pela qualidade do texto verbal integrada aos textos imagéticos relevantes para o leitor infantil. A construção identitária e os conflitos familiares apresentam-se nas obras que não se entregam a discursos maniqueístas e previsíveis, antes convidam à imaginação e à superação dos problemas por meio do pensar e do agir em um mundo, muitas vezes, pouco sensível às necessidades da criança. Embora os temas sejam comuns em livros infantis, ambos os textos são marcados por uma escrita criativa e interessante para as crianças leitoras.
Faustino e o ciclo do demônio logrado na literatura infantil
Authors: Magri da Rocha Guilherme , Pandolfi Maira Angélica
Published: July 2017

Ainda que um tempo considerável tenha se passado desde o início da produção dos primeiros livros para crianças, no final do século XVII, não são poucas as obras de literatura dita infantil que ainda carregam consigo a chave moralizante da tradição pedagógica, que marcou o começo do gênero. Felizmente, este não é o caso de Faustino, um Fausto nordestino, texto de Eliane Ganem que recebeu os prêmios Prêmio INACEN de Dramaturgia e Patativa do Assaré do MinC, sobre a qual este artigo se propõe a apresentar uma possibilidade de leitura. Trata-se de um texto polissêmico em que a escritora constrói como protagonista aquele personagem cuja história é um dos mitos do individualismo moderno: Fausto. Em nossa análise, discutiremos o personagem protagonista tendo em vista a dialogia proposta por Ganem ao remitificar este que é um dos grandes mitos ocidentais. Para isso, utilizaremos como elementos de discussão estudos como os de Joseph Campbell, Jerusa Ferreira e Darío Henao Restrepo.
Cinderela surda: o surdo e o simbólico no conto infantil
Authors: Barbosa de Oliveira Silva Ione Barbosa , Cerqueira Alves Francislene Cerqueira , Tannus Souza Jorgina de Cássia Tannus
Published: July 2017

RESUMO: O presente trabalho propõe-se a analisar o conto Cinderela Surda de Hessel, Rosa e Karnopp (2007), a partir de sua representação e significados simbólicos. O conto analisado é uma releitura da tradicional Cinderela de Perrault (1999) para a realidade dos surdos, ressaltando aspectos pertencentes à cultura e identidade surda. A partir deste conto, interessa-nos compreender e trazer à tona possíveis conflitos e dificuldades enfrentadas pela criança surda. Para isso, tivemos como suporte teórico Bettelheim (1980), Corso e Corso (2006) e Abramovich (1997) na abordagem acerca dos contos infantis e seu material simbólico e Goldfeld (2002), Quadros (1997) e Skliar (1997) no que se refere à criança surda. Compreendemos a partir da análise que a linguagem simbólica pode retratar conflitos internos enfrentados por crianças surdas, permitindo-as entender sobre si mesmas e encontrar significados para suas vidas. Além disso, percebemos a importância de uma literatura surda visando recuperar as tradições culturais de suas comunidades.
Corporate Governance and British Industry
Authors: Jones Geoffrey
Published: July 2017

Cet article décrit l’évolution du système de corporate governance britannique passant d’un capitalisme individuel avant 1945 à un modèle proche des USA depuis quelques années. On retrouve dans les deux systèmes les mêmes préoccupations de court terme. Le récent développement du poids des investisseurs institutionnels a renforcé ces caractéristiques et posé quelques difficultés au maintien des droits de propriétés nationaux dans des industries cycliques et intensives en capital.
Corporate Governance of Zaibatsu during the Inter-war Period
Authors: Takeda Haruhito
Published: July 2017

Structurés autour de la famille et de structures holding, les zaibatsu sont de véritables investissements relationnels. Cette caractéristique de gouvernement d’entreprise est propre à la structure organisationnelle du Japon avant la seconde guerre mondiale. Aussi l’économie de marché joue-t-elle un faible rôle dans les relations de la société mère avec ses filiales. Le cas des zaibatsu est alors caractéristique d’une corporate governance sans marchés financiers et qui n’en conserve pas moins une certaine efficacité.
Le travail des soignants de la psychiatrie française à l’épreuve du New Public Management
Authors: Mougeot Frédéric
Published: July 2017

Les réformes issues du New Public Management ont transformé le système de soin français et la psychiatrie n’est pas en marge de ces mutations. On peut aujourd’hui constater une pénétration de la politique du chiffre dans le monde psychiatrique. Quels sont les effets des politiques managériales sur la pratique soignante en psychiatrie ? Les soignants de cette filière de soins doivent-ils être dorénavant perçus comme des opérateurs de l’ordre gestionnaire ? Fondée sur un important matériau ethnographique, cette contribution propose une plongée dans l’univers des pratiques de santé en psychiatrie dans le contexte actuel de pression des lits.
Penser la complexité, un étayage pour la pratique managériale
Authors: Miailhe Denis , Balas-Ezzemzami Judith , Combes Jean-Marc , Lojou-Julien Chantal
Published: July 2017

Dans un contexte de complexification croissante, de notre place de formateurs et d’intervenants, nous proposons de penser cette réalité en termes de complexité pour l’étayage de la pratique managériale. Quatre pistes s’offrent à nous : réinventer le travail : une valeur ajoutée pour l’entreprise associative ; faire coopérer le stratégique et l’opérationnel : une condition de l’innovation ; investir la fonction des cadres : le lieu où s’articulent instances associatives et réalités de terrain ; former l’encadrement à la compréhension des enjeux : un incontournable de l’engagement associatif.

L’identité au risque de l’altérité : littérature et interculturation
Authors: Jeannin Magali
Published: July 2017

Cette contribution s’intéresse aux valeurs effectivement véhiculées par les dispositifs didactiques centrés sur l’altérité et sur son appréhension dans et par les textes littéraires. Certains supports et/ou exploitations destinés aux élèves, figeant les identités et représentations culturelles, reproduisant voire construisant des stéréotypes, apparaissent inadéquats. Il s’agit donc de dépasser le constat de la différence des cultures, pour engager une dialectique de reconnaissance simultanée du similaire et du dissemblable, à la fois en soi et hors de soi : une expérience d’interculturation qui envisage le concept d’altérité dans sa pleine signification. L’exploitation de deux œuvres de littérature jeunesse, La Montagne aux trois questions (1976) et La Fille du samouraï (2012), est proposée, dans le cadre d’une didactique subjective associant à la prise en compte de l’activité fictionnalisante les enjeux spécifiques de l’éducation interculturelle.
De la transmission de valeurs à l’enseignement de l’ambigüité : la littérature et l’égalité fille-garçon
Authors: Coste Marion
Published: July 2017

L’analyse des réactions d’élèves de lycée à propos de textes permettant des interprétations féministes interroge la façon dont l’étude de la littérature met en branle les représentations des élèves liées au genre. Après avoir explicité le cadre théorique permettant d’affirmer l’ambigüité inhérente au texte littéraire, l’étude décrit des situations d’enseignement dans deux lycées. Le texte littéraire, principalement grâce aux personnages porteurs d’avis et d’expériences variés, sert de médiation et offre aux élèves la possibilité de dire ce qu’ils n’auraient pas dit en leur nom propre. Ils nuancent alors leurs positions et prennent conscience des conséquences de certains préjugés. L’œuvre littéraire permet des interprétations multiples, qui invitent les élèves à émettre des interprétations personnelles et à prendre conscience de certains de leurs modèles de représentation en les confrontant à ceux des autres.
Construire une nation d’agriculteurs : l’« homme économique » et l’attente du développement dans le Malawi postcolonial
Authors: Traugh Geoffrey , Botiveau Raphaël
Published: July 2017

Cet article traite de la façon dont les théories de la raison économique ont transformé la planification du développement agricole dans l’Afrique des années 1960. À partir de l’analyse du travail de la Banque mondiale au Malawi, il montre que l’image de l’« agriculteur maximisateur » a permis aux planificateurs de penser le développement dans des économies dites de subsistance, tout en empêchant aux agriculteurs malawites d’imposer à l’État et aux grands projets de développement mis en œuvre après l’indépendance leurs attentes politiques et leurs perspectives en matière de développement.
Les statistiques comme mode de communication politique. Le cas des premiers plans de développement au Kenya
Authors: Speich Chassé Daniel , Botiveau Raphaël
Published: July 2017

Cet article porte sur l’histoire des statistiques et de la planification du développement. Il montre comment, à travers l’exemple du Kenya, le gouvernement par les nombres est devenu une norme. Les enquêtes statistiques sont comprises ici comme des exemples d’une « société globale » en référence au concept de « situation coloniale » de Georges Balandier. Je propose de voir les statistiques comme un mode de communication entre différents acteurs. Sur la base d’une brève histoire de la planification du développement dans le Kenya colonial tardif et dans les premiers temps de l’indépendance, l’article met en évidence l’usage des statistiques à des fins de communication par les administrateurs coloniaux, les experts des organisations internationales et les politiciens et bureaucrates africains qui prirent les rênes du pouvoir au début des années 1960. Je montre que, lorsque le développement est devenu la raison d’être des organisations internationales et des États nouvellement indépendants dans le Sud global, les débats collectifs sur la définition d’objectifs communs ont perdu en importance face à la prolifération de pratiques de planification chiffrée. Cette dé-politisation a fait de la communication statistique une importante source de pouvoir politique.
