HOLOCENE DEVELOPMENT OF SHELF-PHASE MISSISSIPPI RIVER DELTA PLAINS
Authors: Penland Shea , McBride Randolph A. , Suter John R. , Boyd Ron , Williams S. Jeffress
Published: October 2019

Early delta plain scientists emphasized the concept of the Mississippi River building a single delta plain at the end of the Holocene transgression beginning about 3000-4000 yBP Their work suggests that during the Holocene transgression the rate of relative sea level rise was sufficient enough to prevent delta plain development and as a consequence, the Gulf of Mexico flooded the alluvial valley until the end of the Holocene transgression. Using new geophysical, geotechnical, and radiometric techniques, recent geologic studies of the Mississippi River delta plain and continental shelf reveal the occurrence of several relative sea level stillstands during the last stages of the Holocene transgression. Three shelf-phase delta plains have been identified to date, each separated by a regional transgressive surface of erosion produced by a rise in relative sea level. Sequence stratigraphic relationships suggest that whenever relative sea level rise rates exceed 2 cm/yr for several centuries, the delta cycle process of the Mississippi River stops, and the shelf-phase delta plain undergoes regional submergence and transgression. In contrast, it appears that whenever relative sea level rise rates drop below 2 cm/yr, the delta cycle process operates building a new shelf-phase delta plain.
BEACH REPLENISHMENT ON GULF OF MEXICO SHORELINES
Authors: Pilkey Orrin H. , Dixon Kathie
Published: October 2019

Thirty-five Gulf of Mexico replenished beaches (over 100 pumpings) furnish the basis for this report of the beach replenishment experience through 1988 in the Gulf of Mexico. Beach replenishment along the Gulf shoreline has been sporadic in both application and maintenance. The primary reasons for this appear to be availability of funds and the willingness of communities to meet federal requirements. In at least one case, South Seas Plantation, Florida, the delays associated with the federal funding process led the community to fund their own project. One of the most successful (measured in terms of project lifetime) open ocean shoreline projects is South Seas Plantation, Florida. Among the least successful open ocean projects are Upham Beach, Florida and Grand Isle, Louisiana. Fill densities on the Gulf range from seven to 1,000 m3/m. Projects carried out on the open ocean coast range in length from one to seven kilometers. Since monitoring of replenished beaches is rarely carried out, data are sketchy on the validity of engineering design parameters. Of the beach design parameters investigated including project dimensions, fill grain size, proximity of structures, wave height, and storm frequency, none seem to be of overriding importance in determining beach durability; although beach length and storm history clearly play a role.
DEFINING THE BASINWARD LIMITS OF SALT DEPOSITION, NORTHERN GULF OF MEXICO
Authors: FIDUK J.C. , MCBRIDE B.C. , WEIMER P. , ROWAN M.G. , TRUDGILL B.D.
Published: October 2019

From widely spaced locations across the northern Gulf of Mexico, seismic reflection data suggest the presence of salt at great depth basinward (south) of the Sigsbee Escarpment. Seismic data from east Alaminos Canyon, central Walker Ridge, and easternmost Atwater Valley display strikingly similar reflection character and geometries in the interval between 7.5 seconds and 10.5 seconds of two-way travel time (TWTT). The salt interval lies between the Middle Cretaceous Sequence Boundary (MCSB) and interpreted basement. Above basement and below the base of autochthonous salt is interpreted an interval of variable thickness, composed of synrift and/or early postrift sediments.

The interpreted salt interval is wedge-shaped and pinches out in a basinward direction. The top of the wedge is undulatory while the wedge base appears relatively flat. Flat lying reflections onlap the wedge from a basinward direction. Other onlapping reflections infill the area between undulations on the wedge surface. Internally, mounded seismic character is observed beneath undulation crests, while a more chaotic reflection character is observed between crests, but between lines reflection character is variable. Clear internal reflection terminations are seen downlapping against the base of the wedge as the wedge pinches out basinward. Undulations in the salt wedge’s upper surface are thought to reflect early salt pillow or salt roller development. Salt within the identified interval and possessing the described reflection character and geometry may represent the basinward depositional limit of deformed autochthonous salt. This depositional limit is thought to lie close to the oceanic-extended continental crust boundary.

Similar wedge-shaped structures within this time interval have not been observed south of the Sigsbee Escarpment in Keathley Canyon or western Walker Ridge. The structures may not exist in this area, may be obscure because of poor/sparse data, or existing structures may have already been overridden by the allochthonous salt.
ECONOMIC SUBSALT EXPLORATION IN THE GULF OF MEXICO: PRESENT AND FUTURE CHALLENGES
Authors: FOX JAMES F.
Published: October 2019

Interest in the hydrocarbon potential of the subsalt play in the Gulf of Mexico has continued to grow over the last decade, especially now that the play has produced economic results. The emphasis on economics is crucial. The rapid evolution of ideas on the interaction of sedimentation, salt, and hydrocarbons has been driven by the fact that the oil industry believes that it can make money and generate value for its shareholders, and therefore is willing to invest in research and technical work to support the play.

High drilling costs and a lack of consistent success in finding world-class reserves are two main factors that are generating doubt as to the continued economic viability of the play. However, the industry as a whole must still believe that the future rewards are worth the current investment. Activity at the recent lease sales has been high, and numerous subsalt wells continue to be drilled each year.

Continued success in the short-term will be necessary to maintain the high level of funding for both operations and research. The challenge facing geoscientists is to reduce the exploration risk and attendant high costs by gaining a better understanding of the relationship between salt, sediment, and hydrocarbons.
THE MAHOGANY SUBSALT DISCOVERY: A UNIQUE HYDROCARBON PLAY, OFFSHORE LOUISIANA
Authors: HARRISON HOLLY , ‘CLINT’MOORE DWIGHT , HODGKINS PEGGY
Published: October 2019

The Mahogany subsalt discovery is the petroleum industry’s first commercial subsalt oil development in the Gulf of Mexico. The discovery well tested 7,256 BOPD and 7.3 MMCFD on a 32/64” choke at 7,063 PSI flowing tubing pressure. The primary subsalt reservoir is a high-pressured oil sand with high permeability and porosity and has tremendous deliverability. The field is located 80 miles offshore Louisiana on Ship Shoal South Additions blocks 349/359. The structure is interpreted as a faulted anticline overlain by allochthonous salt. Prestack depth-migrated 3-D seismic data was integrated into a regional geologic model that was based on 2-D time-migrated data. Regionally, the area is characterized by multiple salt sheets, which form a salt canopy sutured east of Mahogany, and several older and deeper sheets are also identified. Subsalt depositional fairways can be approximated by mapping relative salt-induced paleo-bathymetry. Deepwater sand fairways are closely related to salt movements and extend under the salt sheets.
TOWARD AN UNDERSTANDING OF THE DEVELOPMENT OF SALT-RELATED OVERBURDEN STRUCTURES IN THE SOUTHERN NORTH SEA BASIN, U.K.
Authors: HOOPER ROBERT J. , COLLERAN JOHN , GUNN CAROL
Published: October 2019

The present-day structural configuration of the Mesozoic and younger section in the Southern North Sea (SNS) Basin results from the complex interaction between extension, salt tectonics, inversion, and subsidence, that began in the late Triassic and continued well into the Tertiary. Interpretation of high-resolution 3D seismic data, combined with 2D cross-section restorations and the new insights into salt tectonics derived from scaled analog- and numerical-model experiments, has prompted a reevaluation of the development of salt-related structures in the basin. Several key aspects of the developmental history can be well explained using the concepts derived from experimental data notably diapiric rise and fall and inversion-related diapiric rejuvenation.

A wide variety of salt-related structures occurs in the SNS Basin, including graben-diapir systems, salt-walls, and salt swells and troughs. These structures, though physically very different, have similar development histories. Salt-related overburden structures in the basin are considered to result from thin-skinned gravity-driven deformation that was responsible for triggering and controlling graben and diapir growth, and for the selective later inversion of some diapirs. Additional structures were created by bending and vertical movements associated with extensionally-driven diapiric collapse. The development of structures in the overburden was not driven by salt movement; salt structures developed as a simple “reaction” to the thin-skinned extension and subsequent contraction of the overburden.
SALT TECTONICS STRUCTURAL STYLES: CONTRASTS AND SIMILARITIES BETWEEN THE SOUTH ATLANTIC AND THE GULF OF MEXICO
Authors: MOHRIAK WEBSTER UEIPASS
Published: October 2019

The tectonic evolution of the South Atlantic and the Gulf of Mexico salt basins are associated with rupture of Gondwana and the emplacement of oceanic crust in different chronological and geological settings. Salt basins developed diachronously from the Jurassic to the Early Cretaceous, subsequent to an intracontinental rift phase, and were deformed by several tectono-sedimentary episodes in the geologic history, which are responsible for their contrasting halokinetic structural styles. Mechanisms of convergent and divergent radial flow may explain some of the differences between compressional and extensional regimes, but the stratigraphic framework, associated with changing environments of deposition and different episodes of sediment input, controls the formation of extensional and compressional structures, salt mounds, salt diapirs, and salt tongues in different compartments along the sedimentary basins.

Allochthonous salt tongues, which have been thoroughly studied in the Gulf of Mexico, are not so spectacularly developed in the South Atlantic, but some deep water structures bear some resemblance to the Sigsbee Scarp. Fold belts associated with proximal extensional regimes giving way to distal compressional regimes have been identified both in the Gulf of Mexico and in the South Atlantic. The occurrence of systematic arrays of counter-regional (landward-dipping) normal faults has been documented both in the Gulf of Mexico and in the South Atlantic. In the deep water province of the Cabo Frio region, this style of salt tectonics resulted in well-developed antithetic faults responsible for large stratigraphic gaps along the salt weld. Late Jurassic to Early Cretaceous autochthonous halokinetic structures, which are often masked by the phenomenal Miocene-Pleistocene progradation that originated salt tongues and other allochthonous structures, can also be visualized in the northeastern Gulf of Mexico.

Deep seismic reflection profiles have characterized some enigmatic features offshore the northeastern Brazilian margin.

Some of these structures show a moundlike geometry and overlie the rift-drift regional unconformity. Multiple interpretations have been proposed, including tilted rift blocks, reefs, basement highs, volcanic plugs, and even processing artifacts. Some of these features seem to be associated with magmatic activity during the emplacement of oceanic crust, and others occur along fracture zones. On the other hand, some structures show striking evidence of salt tectonics. These features, when analyzed within a basinwide context, have important geologic significance and possible deep-water exploratory plays. Similar structures may be interpreted in the Gulf of Mexico, North Sea, and along the eastern margin of North America.
GEOLOGIC CONTROLS ON STYLE OF SALT PIERCEMENTS IN THE PRICASPIAN BASIN, KAZAKHSTAN: CONTRASTS WITH THE GULF OF MEXICO
Authors: SCHAMEL STEVEN , PILIFOSSOV VICTOR M. , VOTSALEVSKY EDGAR S.
Published: October 2019

The Pricaspian basin at the close of the Paleozoic was a silled, remnant ocean basin about a fourth the areal size of the Gulf of Mexico, but about as deep. In mid-Permian time this basin filled with up to 4.5 km thick succession of evaporites, mainly salt. The evaporites were followed immediately by nearly complete infilling of the basin by Upper Permian-Triassic coarse clastics derived from the southern Urals and other active orogens marginal to the basin. The volume of post-Triassic sediments has decreased through time as the depocenter shifted to the northwest margin of the basin.

The thick original accumulation of salt followed by rapid, and early, nearly complete, infilling of the basin has favored development of massive, uniformly spaced salt stocks and massifs with minor overhangs. Vertical migration of the salt dominates. Allochthonous salt sheets, common piercement structures in the Gulf of Mexico, are not recognized.
FACIES ANALYSIS OF THE LOWER OLIGOCENE T1 SANDSTONE (CARBONERA FORMATION), APIAY FIELD, LLANOS BASIN, COLOMBIA
Authors: MALAGON CLAUDIA , WEIMER PAUL , KRAUS MARY J. , PULHAM ANDREW J.
Published: October 2019

The Apiay field is located in the southwestern part of the Llanos Basin, Colombia. The main Apiay reservoirs are in Upper Cretaceous (Coniacian-Campanian) sandstones. Within the lower Tertiary strata (lower Oligocene), a secondary gas/ condensate reservoir occurs in the lowermost sandstones of the Carbonera Formation, informally named the “T1 sandstone.”

The T1 sandstone is sandstone-rich across the central part of the field and more mud-rich to the west, and is interpreted as representing the fill of a paleovalley. It comprises dominantly marginal marine strata deposited under brackish water conditions, as indicated by a detailed facies analysis, the trace fossil assemblages, and biostratigraphic data.

Lithofacies descriptions recognize the following depositional history within the valley (from bottom to top): a thin interval of fine-grained fluvial sandstone, which rests unconformably over black, shallow marine shales. These fluvial deposits are confined to the deepest part of the paleovalley and have a restricted distribution within the field. There is an abrupt transition upward into marginal marine, brackish deposits composed of medium-grained sandstones, that represent mainly intertidal sandstone bars. The upward change from fluvial deposition to marginal marine is interpreted to reflect an overall transgression during filling of the paleovalley. Marginal marine deposits are volumetrically the most important within the T1 sandstone reservoir.

The T1 sandstone can be divided into two flow units. Flow unit 1 shows poor reservoir quality (porosity 17%, permeability of 146 md); flow unit 2 shows good reservoir quality (porosities 14.5%-15.6%, permeabilities 309-397 md). A zone of lower porosity and permeability (13% and 197 md, respectively) was found within this flow unit.

Published: October 2019

Reservoir sandstone geometry of tide-dominated depositional sequences in the Lower Misoa Formation (lower Eocene), together with multiple northwest-trending normal faults, exerts a strong influence on fluid distribution and poorly swept areas in the VLA-6/9/21 Area in north-central Lake Maracaibo. An integrated reservoir-characterization study by the Bureau of Economic Geology (BEG) and Maraven, S. A., identifies depositional and structural controls on bypassed oil in poorly swept areas adjacent to elongate pathways of water encroachment along depositional axes within sparsely drilled, fault-bounded compartments.

The upper C6 to C3 Members consist of multiple tide-dominated depositional sequences, 30.5 to 91.5 m (100 to 300 ft) thick, bounded below by tidal-ravinement surfaces and capped by flooding surfaces. Each sequence contains multiple parasequences composed of 50- to 100-ft (15.2- to 30.5-m), predominantly upward coarsening, pervasively burrowed sandstones, eroded by cross bedded sandstones. Limited accommodation space resulted in tidal ravinement and erosion of older genetic stratigraphic units. Detailed depositional modeling of these depositional sequences provides a framework for understanding and predicting reservoir drainage patterns and distribution of remaining oil.
A Colônia Benito Mussolini e a formação de Videira/SC: a criação de um Brasil europeu no Vale do Rio do Peixe e a manutenção das estruturas de preconceito em um território outrora caboclo

Ao entender que uma região é composta por diversos grupos que compõem sua população, cuja saga jamais será relativa a uma única etnia, mas dialogará com a trajetória de diferentes grupos em um complicado equilíbrio dotado de múltiplas variáveis, pode-se traçar caminhos teóricos capazes de fornecer relações entre a formação de um território e a trajetória dos povos que territorializam o espaço. A partir do território, busca-se criar um diálogo entre a formação de Videira/SC, criada oficialmente a partir da colonização estruturada como uma cultura “europeia” em um território caboclo marcado pelo genocídio de sua população a partir da Guerra do Contestado. Em uma análise bibliográfica, valendo-se ainda da história oral através de entrevista semiestruturada, busca-se evidenciar a invisibilidade sobre a memória e cultura cabocla na cidade formada a partir de diversas colônias organizadas a partir de premissas étnicas que tem, em sua estrutura profunda, a manutenção e o fomento das estruturas de preconceito, especialmente racial, permeando a história oficial.
Geopolítica dos recursos naturais estratégicos e questão agrária em Moçambique: a Vale S.A. e o extrativismo epidêmico

Published: October 2019

Moçambique possui algumas das maiores reservas de recursos naturais de potencial energético do mundo, sobretudo, carvão mineral, gás natural e, mais recentemente descoberto, petróleo, ainda que em menor quantidade. Os recursos naturais energéticos são, ou podem ser, instrumentos de poder ou armas políticas. Destarte, determinam e condicionam ações sobre o uso dos territórios. Território e poder determinam relações instáveis e motivam pretextos para o surgimento de práticas e estratégias geopolíticas e todo recurso é produto de uma relação de poder sobre determinado território. Assim, os recursos naturais energéticos são considerados estratégicos, produtos das relações sociais de produção e do poder que interfere diretamente na posse dos mesmos e controle territorial, o que envolve, também, a conflitualidade gerada a partir da intensificação da questão agrária resultante desses processos.Palavras–chave: Geopolítica dos recursos naturais, questão agrária, território, poder, MoçambiqueAbstract Mozambique has some of the world's largest reserves of natural resources with potential for energy, mainly mineral coal, natural gas and, more recently, oil, although in a smaller amount. Natural energy resources are or may be, instruments of power or political weapons. Thus, they determine and condition actions on the use of territories. Territory and power determine unstable relationships and motivate pretexts for the emergence of geopolitical practices and strategies, and every resource is the product of a power relationship over a given territory. Thus, natural energy resources are considered strategic, products of social relations of production and power that directly interfere in their possession and territorial control, which also involves the conflict generated by the intensification of the agrarian issue resulting from these processes.Keywords: Geopolitics of natural resources, agrarian question, territory, power, Mozambique
GLiMPSE - A Framework for Evaluating UX in Games
Authors: Carvalho Vítor Marques , Furtado Elizabeth Sucupira
Published: October 2019

The gaming industry has grown considerably in the last decades, designing experiences and interactive platforms through games, an entertainment media from the popular culture. With the advancement of technologies and user experience design methods, a challenge is faced for the constant improvement of the characteristics of a game aiming to improve the enjoyment and immersion perceived by users. To face this challenge, we designed a conceptual framework named GLIMPSE based on constructs used to evaluate user experiences with games. GLIMPSE brings together concepts of presence and interaction, goals, learning, context, and immersion used to evaluate experiences with games. Its applicability was tested through a questionnaire answered by 241 users from gaming forums and communities. The results provide insights revealing the GLIMPSE conceptual framework to be a useful tool for evaluating experiences in games by assessing the main UX elements and their existing overlap.

A criação de jogos educacionais é uma tarefa complexa e interdisciplinar. Para que os elementos do jogo sejam adequados aos usuários finais é importante projetá-lo envolvendo as partes interessadas e técnicas de Design Participativo (DP) permitam a efetiva inserção dos usuários no processo de design. No caso de design com crianças surdas ou com deficiência auditiva (S/DA), um dos desafios é a identificação de soluções de DP que permitam a participação desses sujeitos. Apresentamos neste artigo um relato de experiência de design de jogos educacionais com a participação de crianças S/DA. Foi realizado um estudo de caso em uma escola estadual para surdos, com uma turma de 1º ano do ensino fundamental, uma professora e duas intérpretes de Libras, cujo elemento propulsor foi a criação de jogos educacionais para ensino de letras e números, como parte de uma demanda pedagógica existente. Foram produzidos dois jogos digitais feitos por e para crianças S/DA. Elas se reconheceram como produtoras dos jogos e, além disso, os jogos criados tendem a refletir elementos subjetivos e culturais próprios dos seus criadores.

Liver transplantation (LT) is a common current technique for end-stage liver disease. Complications after the surgical procedure, though uncommon, can be of very different origin and can also be severe enough to lead to liver and multiorgan failure and finally graft loss and/or recipient’s death. Intensivists and the surgical team must be familiarized with these early complications to detect them as soon as possible in order to use the best diagnostic tools and take the best therapeutic measures to restore anatomical integrity and organ function to optimize the liver graft. In this chapter, we present an updated state of the art for efficiently tackling with all different, most usual complications that an LT patient can present during early postoperative period.
Consciousness: The Point of View of Process Philosophy and Genetic Structuralism
Authors: Riffert Franz ,   Bulgarian Academy of Sciences
Published: October 2019

First a sketch of the current state of the debate of the phenomenon of consciousness is provided; based on it David Chalmer’s distinction between the weak and the hard problem of consciousness will be introduced. It will be indicated that Whitehead’s process philosophy is able to offer a promising basis for solving the hard problem by showing how the concept of consciousness is anchored in his metaphysical theory. In the remaining parts of the paper the so-called weak problem of consciousness will be addressed in more detail by comparing Whitehead’s speculative account with Piaget’s empirical research results concerning the phenomenon of consciousness. By showing that Whitehead’s and Piaget’s positions on consciousness overlap widely a kind of indirect empirical support of Whitehead’s philosophical position will be achieved. At those points where the two positions deviate – that is in only two points – there are indications that Whitehead holds the more plausible position. So this investigation confirms William Seager’s suggestion that more attention should be drawn to Whitehead’s process philosophy when trying to solve the hard, as well as the weak problem of consciousness. In order to substantiate this claim two topics are discussed from the point of view of Whitehead’s position of consciousness: (a) learning and consciousness and (b) artificial consciousness.
Newton’s Bucket (Thought) Experiment
Authors: Malec Maja ,   Bulgarian Academy of Sciences
Published: October 2019

The bucket experiment in Newton’s Principia is quite simple. Nonetheless, physicists as well as philosophers and historians of science are still debating its purpose and success. I present two interpretations found in the literature. According to the first, Newton tries to prove absolute rotation and thus the existence of absolute space. According to the second, he tries to provide a definition of absolute rotation as it is used in his mechanics. Closely connected to this is his rejection of Descartes’ explanation of rotation and of motion in general. I conclude with a short discussion on whether the bucket experiment can be classified as a thought experiment.

L’INTERFACE COMMERCE-CULTURE ET LA QUESTION DU RÈGLEMENT DES DIFFÉRENDS
Authors: Gagné Gilbert
Published: October 2019

Le traitement des biens et services culturels relève, en droit international, à la fois de l’OMC et de l’UNESCO et pose donc la question des liens entre les dispositions de chaque régime, particulièrement en ce qui touche au règlement des différends. Une jurisprudence en matière de produits culturels devrait émaner du mécanisme de règlement des différends prévu par la Convention sur la protection et la promotion de la diversité des expressions culturelles afin d’assurer que cette jurisprudence repose sur des considérations culturelles. Cependant, dans la mesure où le mécanisme de règlement des différends de l’OMC est de loin le plus élaboré et le plus utilisé, c’est ce dernier qui risque de développer une telle jurisprudence. Pour autant que la Convention reflète un consensus international quant au traitement des produits culturels, cette dernière pourrait influencer les conclusions des instances de règlement des différends à l’OMC.
De l’usage du droit international au Moyen-Orient : approche critique
Authors: Mohammedi Adlene
Published: October 2019

En sortant d’une approche positiviste et en abordant le droit international public sous un angle critique, l’usage prend le pas sur le cadre. Au Moyen-Orient, le droit apparaît comme un outil ambigu au service de diverses stratégies et mobilisé par divers acteurs. À travers des exemples précis (la question palestinienne; la politique israélienne; le Liban; les conflits libyen et syrien; la politique russe dans la région), nous nous rendons compte que le droit international est avant tout une langue. Du moins, il est possible d’affirmer qu’il n’est jamais ce qu’il prétend être. Une désacralisation du droit devient alors nécessaire, salutaire. Il ne s’agit cependant pas ici d’une désacralisation nihiliste, mais d’un travail serein de déconstruction qui conserve une certaine place à la notion de souveraineté. Nous pouvons ainsi affirmer que notre approche est une approche réaliste-critique. Critique sur les utilisations contemporaines du droit international et réaliste quant à l’importance du cadre stato-national, et donc de la souveraineté, objet de notre conclusion.
Le retrait de la déclaration du Rwanda permettant aux individus et ONG de saisir la Cour africaine des droits de l’homme et des peuples
Authors: Pavot David
Published: October 2019

Le 1er mars 2016, le Rwanda informait la Cour africaine des droits de l’homme et des peuples du retrait de sa déclaration émise au titre de l’article 34(6) du Protocole relatif à la Charte africaine des droits de l’homme et des peuples portant création d’une Cour africaine des droits de l’homme et des peuples permettant aux individus et ONG de saisir la Cour à son encontre. Non prévue par cette dernière, l’hypothèse de retrait posait à la Cour plusieurs défis en raison des affaires pendantes impliquant le Rwanda mais surtout en raison du faible nombre d’États ayant soumis de telles déclarations. Au-delà des enjeux propres à la Cour, le retrait rwandais suscitait plus largement une interrogation relative à l’interprétation des actes unilatéraux. En effet, il s’agissait – pour la Cour – d’une occasion de clarifier les règles applicables à celle-ci. Malheureusement, l’arrêt de la Cour africaine des droits de l’homme des peuples du 3 juin 2016 dans l’affaire Victoire Umuhoza Ingabire c. Rwanda se limite à une analogie avec la Convention de Vienne sur le droit des traités et ni ne renouvelle, ni ne clarifie les règles d’interprétation des actes unilatéraux.
La sociologie de l’éducation au Québec : entre discipline et spécialité
Authors: Doray Pierre , Groleau Amélie
Published: October 2019

Il y a plus de cinquante ans maintenant, le Québec était traversé par de grandes réformes du système éducatif au cours de la Révolution tranquille. Les sociologues ont non seulement pris part aux changements, ils en ont également examiné les effets, critiqué les manques, documenté les solutions alternatives, etc. Ce faisant, ils ont participé à la formalisation de la sociologie de l’éducation québécoise. Cet article traite de l’évolution de cette spécialité au Québec au cours des dernières décennies. Prenant appui sur le concept d’institutionnalisation des disciplines scientifiques, il examine l’émergence de la sociologie de l’éducation sur le plan social et intellectuel en lien avec le contexte politique et social québécois. Quelles furent les étapes de sa structuration ? Quels furent les moments forts et les grands thèmes étudiés ? Quelle est la place de la sociologie de l’éducation au Québec en sociologie et en éducation à l’heure actuelle ? Il ressort de cet état des lieux que malgré une influence marquante au cours des années 1970, le poids formel de la sociologie de l’éducation est aujourd’hui relativement faible tant par rapport aux sciences de l’éducation qu’à la sociologie en général. Toutefois, cette spécialité demeurerait pertinente en raison de l’arrimage entre sa production scientifique et les changements sociaux et politiques dans le champ de l’éducation.
DEFICIT ALFA-1 ANTITRIPSINA

Deficit alfa-1 antitripsina je relativno retko i klinički veoma heterogeno autozomnorecesivno oboljenje iz grupe serpinopatija. Javlja se u svim populacionim grupacijama,a najčešće kod naroda evropskog porekla (1:2000-5000), posebno severnoevropskog(1:1600). Klinički ispoljene oblike bolesti karakteriše progresivna destrukcija jetre i pluća,a ređe druge manifestacije. Iako nizak serumski nivo alfa-1 antitripsina u odsustvuhipoproteinemije i inflamacije gotovo redovno ukazuje na prisustvo bolesti, za pouzdanudijagnozu je neophodna njegova fenotipizacija ili genotipizacija. Terapija bolestije dosta kompleksna i zavisna od tipa deficita. Najčeći oblik bolesti zahteva primenuodgovarajućih mera usmerenih na supresiju progresije pulmonalnih i hepatičnih lezija.Teška forma plućne bolesti iziskuje aerosol ili intravensku primenu alfa-1 antitripsina,a hepatična adekvatan dijetetsko-terapijski tretman. Jedino rešenje kod bolesnika saterminalnom insuficijencijom jetre i pluća je transplantacija ovih organa.

The giant panda (Ailuropoda melanoleuca) is one of the most endangered mammals, and its conservation has significant ecosystem and cultural service value. Cytosine DNA methylation (5mC) is a stable epigenetic modification to the genome and has multiple functions such as gene regulation. However, DNA methylome of giant panda and its function have not been reported as of yet. Bisulfite sequencing was performed on a 4-day-old male giant panda’s brain, liver and pancreatic tissues. We found that the whole genome methylation level was about 0.05% based on reads normalization and mitochondrial DNA was not methylated. Three tissues showed similar methylation tendency in the protein-coding genes of their genomes, but the brain genome had a higher count of methylated genes. We obtained 467 and 1,013 different methylation regions (DMR) genes in brain vs. pancreas and liver, while only 260 DMR genes were obtained in liver vs pancreas. Some lncRNA were also DMR genes, indicating that methylation may affect biological processes by regulating other epigenetic factors. Gene ontology and Kyoto Encyclopedia of Genes and Genomes analysis indicated that low methylated promoter, high methylated promoter and DMR genes were enriched at some important and tissue-specific items and pathways, like neurogenesis, metabolism and immunity. DNA methylation may drive or maintain tissue specificity and organic functions and it could be a crucial regulating factor for the development of newborn cubs. Our study offers the first insight into giant panda’s DNA methylome, laying a foundation for further exploration of the giant panda’s epigenetics.

Aims : This study aims to determine the organoleptic characteristics of different formulations nectars elaborated with ginger oleoresin.

Study Design : Ginger nectars were formulated, using a composite central plan, from oleoresin or ginger rhizome, lemon juice and sugar. Then, they were subjected to sensory analyzes.

Place and Duration of Study : The study was conducted, between November and December 2017, at the Biochemistry and Food Sciences Laboratory of the Félix Houphouët-boigny University.

Methodology : Seventeen (17) nectars formulas were established by considering varying amounts of three ingredients: oleoresin (X1), sugar (X2) and lemon juice (X3) according to a composite experimental plan. The acceptance of these nectar formulas with consumers has been estimated. The intensities of perception of their color, texture and flavor were also evaluated relative to the artisanal nectar of ginger taken as a control. The sensory evaluation was carried out by panels of tasters.

Results : The hedonic analysis indicates that in addition to the control Ft accepted at 91.43% by the tasters, the formulations F2; F8; F12; F13 and F14 are preferred in proportions ranging from 57.14% to 77.15%. The intensities of the organoleptic characteristics of these nectars are translated by sensory profiles. The formulations F2; F8; F12; F13 and F14 are yellow while the control is brown. As regards the texture, the control has a turbidity more pronounced than the formulations. While the intensities of the fluidity and homogeneity are higher for formulations F2; F8; F12; F13 and F14 than the control. In addition, the control Ft appears sweeter and more acidic than the formulations. This character is also observed in the flavors of gnamankou and lemon.

Conclusion : The formulations F2; F8; F12; F13 and F14 close to the witness would be indicators for producers of ginger nectar.

Fruits are susceptible to insect pest infestations, bird attack, various pathogens, and mechanical damages, all of which can reduce their commercial value and thereby cause significant yield and economic losses. The objective of this study was to control mango pests and diseases as well as to improve the fruit quality of mango through bagging technology. An investigation was performed during the year 2016 from March to July for safe mango production by applying minimum use of pesticide entitled studies on influence of bagging on physico-chemical properties and shelf life of mango cv. Langra. The mango fruits were bagged at marble stage (40 days from fruit set) with different types of bags which constituted the various treatments viz: T1: Brown paper bag; T2: White paper bag; T3: Polythene bag T4: Muslin cloth bag; T5: No bagging (control). Bagging with brown paper bag and white paper bag improved fruit retention, weight of fruit, diameter of fruit, pulp weight, total soluble solids, ascorbic acid, percent of citric acid, reducing sugars and β-carotene at harvest and ripe stage over control. Brown paper bag changed fruit color. In all cases good quality, cleaner, disease and insect free fruits were harvested. The sensory qualities in fruits of brown, white and muslin cloth bags were improved over control. Pre-harvest bagging also reduced occurrence of spongy tissue and the incidence of mealy bugs. These results indicate that fruit bagging can improve fruit quality through reduction in disease and insect-pest attack and shelf life of mango cv. Langra.
On Chebyshev and Riemann-Liouville Fractional Inequalities in q-Calculus
Authors: Ajega-Akem Stephen. N. , Iddrisu Mohammed M. , Nantomah Kwara
Published: October 2019

This paper presents some new inequalities on Fractional calculus in the context of q-calculus. Fractional calculus generalizes the integer order differentiation and integration to derivatives and integrals of arbitrary order. In other words, Fractional calculus explores integrals and derivatives of functions that involve non-integer order(s). Quantum calculus (q-Calculus) on the other hand focuses on investigations related to calculus without limits and in recent times, it has attracted the interest of many researchers due to its high demand of mathematics to model complex systems in nature with anomalous dynamics. This paper thus establishes some new extensions of Chebyshev and Riemann-Liouville fractional integral inequalities for positive and increasing functions via q-Calculus.
Information-Seeking Behaviour of Women Regarding Household Health and Hygiene Practices
Authors: Kaur Loveleen , Kaur Sukhjeet , Sharma Preeti
Published: October 2019

Background: Inadequate health and hygiene practices have direct effect on health of the individual, family, communities and nation as a whole. The knowledge about different health and hygiene practices depends largely upon the sources from where we regularly get information. Women tend to be the primary health information seekers for family and for themselves. Therefore there is a need to study their information seeking behaviours.

Aim: The present study was conducted with the objectives to identify the information-seeking behaviour of women regarding household health and hygiene practices, and to ascertain the relationship of information-seeking behaviour of women with their household and socio-economic characteristics.

Methodology: The study was conducted in Ludhiana district of Punjab. Two blocks and two zones were selected purposively from Ludhiana district. Further two villages from each block and two localities from each zone were selected randomly. Twenty five women from each selected village as well as from each locality in the age of 25-50 years were selected on random basis. Thus, a total of 200 women formed the sample for the study and data was collected with the help of an interview schedule.

Results: Information-seeking behaviour was studied in terms of information needs, use of information source and information source evaluation. Findings of the study revealed that majority of the respondents i.e. 59 per cent had low information needs for selected household health and hygiene practices. Informal sources were the most frequently used sources of information whereas use of all information sources by most of the respondents (98%) was found to be low. Around 40 per cent of the respondents never evaluate the source of information while looking for information on household health and hygiene practices. Half of the respondents (50%) had active information-seeking behaviour regarding household health and hygiene practices.

Conclusion: Information-seeking behaviour of the respondents was positively correlated with their education, occupation and mass media exposure while age of the respondents and the family type were negatively correlated with their information-seeking behaviour.

In non‐metallic atom‐doped carbonaceous materials, the disparity in electronegativity between the doped constituents and carbon atoms predetermines the bonding topology of covalent bonds and the distribution of electron density. This, consequently, influences the polarization and electron transport behavior within the doped domain and the electromagnetic wave attenuation attributes of the carbonaceous material. However, the influence of covalent bonds formed by doping with weakly electronegative atoms on electron density distribution, polarization effects, and electromagnetic wave attenuation remains uncharted. To address this deficiency, this study fabricates a porous carbonaceous material (NCP) and incorporates boron‐doped atoms to form a material with tunable B─C bonding configurations (B‐NCP). By modulating the B─C bonding configuration and proportion, it is feasible to achieve the synergistic optimization of conductive loss and polarization loss of the B‐NCP specimen. The optimized prototype B‐NCP‐1200 sample displays exceptionally efficient electromagnetic wave absorption capabilities with a minimum reflection loss (RLmin) of −52.03 dB and an effective absorption bandwidth (EAB) of 5.36 GHz. This study presents a conscientious model for comprehending the electromagnetic attenuation mechanisms associated with weakly electronegative atom doping in carbon‐based electromagnetic wave‐absorbing materials.

Liposomes are established in the clinic as drug delivery system, and can be designed for heat‐triggered drug release. Thermal nanotherapies, like magnetic nanoparticle hyperthermia (MNH) and photothermal therapy (PTT), show great promise for cancer therapy and other diseases, but the great challenge of them is temperature detection. In this study, a thermoluminescent vesicle for real‐time monitoring of PTT and MNH is developed. The temperature sensor is a liposome containing IR780 dyes incorporated in the membrane. For PTT, the liposome is the thermal agent and temperature sensor, while for MNH only the sensor, since the nanoheaters are Mn‐based iron oxide nanoparticles. Mn‐ferrite nanoparticles showed a good response at low field MNH conditions. The photothermal conversion efficiency of the liposomes altered from 11% to 22%. Thermal sensitivity varied from 0.3% to 5.0% and change after freeze‐drying, while repeatability ranged from 0.91 to 0.98. Photostability studies of MNH and PTT with five heat‐cooling cycles confirmed the temperature sensor application. In vivo and post‐mortem studies using the B16F10 murine tumor model are reported. After intratumoral injection of the thermoluminescent vesicle a blue‐like fluorescence peak shift of ≈20 nm is observed, which maintains the thermometry capabilities and reveals remotely the intratumoral temperature during PTT. The results demonstrate that the near‐infrared thermoluminescent liposome is able to real‐time monitoring the thermal therapy.
