Le recours à l’Angleterre dans les débats publics de la France révolutionnaire
Authors: Dupuy Pascal 
Published: October 2019

Pour beaucoup de députés, au-delà de leurs convictions philosophiques ou politiques, il s’agissait pour la plupart, à la suite d’un mouvement initial de sympathie pour le réformisme anglais, de ressusciter ou de maintenir un courant anglophobe dont les racines sortaient en réalité renforcées depuis au moins le milieu du siècle. Ces sentiments hérités d’anglophobie chez les députés se coulent dans la réalité des rapports entre révolution et contre-révolution et se réactualisent dans le contexte politique et diplomatique d’après 1792. Les principes de souveraineté générale, de droit des peuples à l’exercice de leur souveraineté nationale s’accordaient assez mal avec « l’impérialisme » politico-naval et la domination commerciale de l’Angleterre.
L’énigme, une clef d’interprétation de l’architecture ?
Authors: Léchot Timothée 
Published: October 2019

Dans les périodiques du XVIIIe siècle, un nombre remarquable d’énigmes et de logogriphes porte sur l’architecture. Les réponses de ces devinettes versifiées peuvent désigner des constructions connues de tous, comme le château de Versailles ou la colonnade du Louvre, des réalisations qui caractérisent l’espace urbain, comme les enseignes des marchands, ou des éléments qui relèvent de l’espace domestique, comme la cheminée ou l’escalier. À côté d’autres sources, les énigmes déploient un imaginaire architectural qui reste à étudier. Elles révèlent certains traits saillants des motifs architecturaux dans les représentations collectives et permettent de suivre l’évolution de ces représentations sur une longue période. Réciproquement, il existe un imaginaire architectural de l’énigme : ce jeu littéraire possède sa propre architecture textuelle labyrinthique que les auteurs et les théoriciens cherchent à définir. Dans cette perspective, beaucoup de textes décrivent des motifs ou des espaces qui troublent la frontière entre l’intérieur et l’extérieur, le privé et le public, le caché et le visible. Enfin, l’énigme et le logogriphe apparaissent comme des entreprises ludiques de déconstruction. En démembrant et en recomposant des mots, les devinettes explorent l’architecture du langage.

Como describe Botero y Restrepo, la toxoplasmosis es una infección producida por un protozoo Toxoplasma Gondi intracelular de la subclase coccidia que afecta a una parte de la población en todo el mundo, se asocia con una infección congénita y abortos. El objetivo de este estudio es determinar serológicamente la presencia de Anticuerpos IgM del Parasito Toxoplasma Gondii en mujeres embarazadas que habitan en la Zona número 4 de Juigalpa. La investigación se llevó a cabo con el propósito de conocer el grado de positividad que presentaban las muestras sanguíneas de estas personas, el instrumento utilizado en esta investigación fue la encuesta y el análisis serológico a muestras sanguíneas, los datos obtenidos fueron insertados en un programa probabilístico (SPSS).
Esta investigación se posiciona en el paradigma positivista, en el que participaron 21 mujeres embarazadas. El examen de Toxoplasma gondii se llevó a cabo a través del método ELISA IgM. El 23.8% del 100% de las muestras analizadas provenientes de las participantes en la investigación, presentaron positividad para anticuerpos de tipo IgM, lo cual es un peligro para una mujer embarazada ya que si la madre se infecta de toxoplasmosis durante el embarazo, hay muchas posibilidades de que transmita la infección al feto, y el porcentaje de riesgo de transmisión es mayor cuanto más avanzada se encuentra la gestación en el momento de contraer la infección, siendo del 15% si esta ocurre durante el primer trimestre, del 30% durante el segundo trimestre, y llegando al 60% en el tercer trimestre
Endoscopic transnasal resection of tuberculum sellae meningioma - case report
Authors: Kozok-Paździor Monika , Dobosz Paweł , Sobolewska Aleksandra , Sobański Dawid 
Published: October 2019

Introduction: Tuberculum sellae meningiomas (TSM) represent 5-10% of all intracranial meningiomas.	Tumours are located on tuberculum sellae or chiasmatic sulcus of the sphenoid bone. These suprasellar lesions often displace the optic nerves causing visual impairment that is commonly the presenting symptom. Tuberculum sellae meningiomas are traditionally operated by transcranial approach. There is an alternative method to remove tumours of anterior skull base by using endoscopic transnasal surgery. Methods: In this article we describe a case of the patient with tuberculum sellae meningioma. Results: 63-year old women was diagnosed due to a headache, facial sensation defects on the right and peripheral vision loss. Ophthalmology examination showed bitemporal vision loss up to 10-15%. Using magnetic resonance imaging scan the tumour of diameter 8.1x8.0mm was located in tuberculum sellae. The endoscopic transsphenoidal operation was made confirming diagnosis of meningioma. In postoperative period the symptoms was almost completely minimalized. Conclusion: The treatment of choice for tuberculum sellae meningiomas is a surgery. Neurosurgeons have two options to remove the tumour: by transcranial approaches or via endoscopic transsphenoidal surgery with rhinologist. The decision of the optimal surgical technique should be individually made. Knowing possible complications during endoscopic approach, the benefits prevail. Cerebrospinal fluid leak is still challenging but using nasoseptal flap (Hadad’s flap) makes reconstruction easier. Recovery is quicker and postoperative results are promising.
UPPER PLEISTOCENE TO RECENT SHELF AND UPPER-SLOPE DEPOSITS OF OFFSHORE MISSISSIPPI-ALABAMA
Authors: KINDINGER JACK L. 
Published: October 2019

ABSTRACT
A high-resolution single-channel seismic survey of the Mississippi-Alabama continental shelf and upper slope revealed relatively thin upper Pleistocene and Holocene deposits. The stratigraphy was defined by identifying depositional and erosional episodes recognized on seismic profiles by geomorphic patterns, high-angle clinoform progradational deposits, buried stream entrenchments, planar conformities, and erosional unconformities.
The regional bathymetry shows a gently sloping shelf with a relatively steeper continental slope. Local tectonics have had minimal effect on the shelf, with surface and subsurface faults exhibiting a random pattern. Diapirs on the shelf break and upper slope, in contrast, have created several topographic highs with associated faults.
The upper Pleistocene shelf and slope deposits are examples of two depositional environments, including four differentiated areas: inner shelf, middle shelf, outer shelf, and upper slope. The presence of sandy sediments in the shelf deposits is inferred to be the result of reworking by marine processes.
A five-stage model of sedimentation and shelf evolution is presented. The earliest stage (stage 1) is the early Wisconsinan transgression across a seaward-sloping erosional horizon. During the transgression, this paleosurface was overlain by a thin (&lt; 10 m) layer of sediments (stage 2). The third stage was the late Wisconsinan regression, during which fluvial channels eroded the shelf, forming a thick (&gt; 90 m) shelf margin delta. The Holocene transgression deposited a thin layer of sediment over parts of the shelf (stage 4). The last depositional episode occurred during the Holocene highstand and was the progradation of the St. Bernard delta (stage 5).
REASONS FOR AND SIGNIFICANCE OF DEEP, HIGH-RANK HYDROCARBON GENERATION IN THE SOUTH TEXAS GULF COAST
Authors: Price Leigh C. , Clayton Jerry L. 
Published: October 2019

ABSTRACT
Organic geochemical analyses of Tertiary to Jurassic rocks from a 6,704 m wellbore in LaSalle County, Texas (interior South Texas Gulf Coast) revealed two hydrocarbon (HC) generation zones: a shallow (2,255–2,682 m) zone with a HC concentration maximum at a vitrinite reflectance (Ro) of 0.9, and a deep zone (4,000–5,791 m) with a HC concentration maximum at Ro = 3.4.
The shallow zone was due to generation from terrestrial-based (Type III) organic matter (OM), and organic-geochemical data of this zone agreed with results of other studies of HC generation from Type III OM and closely followed the generally accepted model of organic metamorphism. In contrast, the deeper, carbonate-rich, Lower Cretaceous to Jurassic rocks contained a marine-derived OM, and significant organic-geochemical changes accompanied this change in OM type at a lithologic break at 3,300 m in the well bore: 1) Hydrogen indices sharply increased. 2) ROCK EVAL Tmax and Transformation Ratio values sharply decreased. 3) Gas chromatograms of C15+ saturated and aromatic HCs had mature characteristics above the break and immature characteristics below the break. 4) In both the saturated and aromatic HCs, molecular compositions and compound ratios, which had been continually increasing to mature values with depth, strongly reversed themselves to very immature values. The immature characteristics of bitumen from the carbonate-rich rocks below the lithologic break are believed to be largely original characteristics which had not yet been diluted by significant HC generation.
Below the lithologic break, the maturity of both the saturated and aromatic HCs increased up to a deep generation zone defined by a sharp increase in the concentration of C15+ bitumen at 4,116 m (Ro = 1.9), followed by increases in the concentrations of C15+ saturated and aromatic HCs at 4690 m (Ro = 2.5), and 4,910 m (Ro = 2.8), respectively. A maximum in C15+ HC and bitumen concentrations at 5,242 m (Ro = 3.4) was followed by a decrease to background values by 5,821 m (Ro = 4.5) from primary migration. Thus, a generation sequence was encountered of resins and asphaltenes being generated first, followed by saturated and then aromatic HCs. A thermal deadline for C15+ HCs was apparently being approached at well bottom at Ro = 7.0.
The moderate to high amounts of C15+ bitumen and HCs, and the measurable to moderate amounts of generation potential in the deep, high-rank (Ro = 1.3–7.0) rocks of this well bore do not agree with the hypothesis of a thermal deadline for C15+ HCs in fine-grained rocks by Ro = 1.35. The organic maturation path of the marine-derived (presumed hydrogen-rich OM) from the deep rocks of this well supports the conclusions of other studies, that hydrogen-rich OM may have higher activation energies than Types II-S and III OM and therefore requires higher burial temperatures and maturation ranks to initiate and sustain HC generation and primary migration.
On the Origin of Hydrocarbons in the Gulf of Mexico Basin–A Reappraisal
Authors: Bissada K. K. , Katz B. J. , Barnicle S. C. , Schunk D. J. 
Published: October 2019

The origin of hydrocarbons in the Gulf of Mexico basin has been a subject of controversy for many years. One series of arguments invokes source rocks of average organic enrichment, pervasively distributed throughout the Cenozoic sequence and intimately associated with the reservoir system. Other arguments invoke organic-rich, discrete source rocks not in direct contact with the reservoirs, possibly in pre-Tertiary sequences drained by deep-rooted faults and piercement structures.
Geochemical analyses of hundreds of crude oils, natural gases, and nonreservoir rocks from the Mesozoic and Cenozoic trends along the northern Gulf of Mexico basin and from DSDP sites indicate the general inadequacy of the Oligocene to Recent section to source significant oil accumulations. Furthermore, isotopic data indicate that much of the gas found in Neogene and Quaternary reservoirs is thermogenically derived from much greater depths where maturation is consistent with dry gas generation.
Geochemical data from several Mesozoic and Paleogene units in the basin indicate the existence of excellent oil-prone source rocks. It is proposed that such units extend below Cenozoic producing trends and are drained by deep-rooted faults and piercement salt structures. Maturation history, structural style, and patterns of migration and remigration control the variable productivity along the various trends.
Evidence for Large-Scale Vertical and Lateral Migration of Formation Waters, Dissolved Salt, and Crude Oil in the Louisiana Gulf Coast
Authors: Hanor Jeffrey S. , Sassen Roger 
Published: October 2019

Spatial variations in properties of both inorganic and organic components of Louisiana Gulf Coast fluids provide insight into migration pathways of formation waters and hydrocarbons. The salinity variation of subsurface formation waters, for example, helps delineate the regional permeability field of a sedimentary basin and pathways of long-range solute transport. Variations in the carbon isotopic composition of crude oils help to establish sources of hydrocarbons and pathways of migration.
In the Louisiana coastal parishes, aqueous fluid flow directions in most of the deep, geopressured sediments are nearly vertically up. Contrary to the presumed membrane behavior of the shale-rich sediments of the geopressured zone, however, pore water salinities also increase upward. It is possible, therefore, that fluids are being channeled through fractures and faults, rather than through matrix porosity. Geochemical characteristics of crude oils in thermally immature Tertiary reservoirs of the shallow hydropressured zone suggest that they have been emplaced by vertical migration from deeper and older geopressured source rocks.
The 2 to 3 km-thick, sand-rich hydropressured zone which overlies the geopressured sediments in south Louisiana is far more dynamic hydrologically than previously recognized. Dissolution of salt diapirs generates brines at shallow depth and helps to produce pore-fluid density inversions sufficient in magnitude to drive large-scale vertical and lateral flow. Vertical mixing of oxygenated meteoric and formation waters may explain the presence of many biodegraded crude oils in south Louisiana.
Calculated fluid flow directions in the geopressured zone north of the coastal parishes have a pronounced lateral component to the north. Regional variations in pore water salinities suggest that fluids from the overpressured zone are channeled laterally updip through regionally continuous sand sequences of the Wilcox Group where they mix with brines formed by the dissolution of salt domes in the Northern Louisiana and Mississippi salt basins 200 km to the north. Geochemical characterization of crude oils in Wilcox reservoirs in this area suggests that long-range lateral migration from deeply buried Lower Tertiary source rocks to the south has occurred. Some of these crude oils have been altered by water washing, suggesting a zone of significant fluid flow exists along the axis of the Mississippi Embayment.
BIPOLAR SIMPLE-SHEAR RIFTING RESPONSIBLE FOR DISTRIBUTION OF MEGA-SALT BASINS IN GULF OF MEXICO?
Authors: WATKINS JOEL S. , MacRAE GRANT , SIMMONS GREGORY R. 
Published: October 2019

ABSTRACTMajor salt basins in the Gulf of Mexico region are distributed in a diagonally symmetric manner with greatest abundances of salt located in the northeastern (Texas-Louisiana shelf and slope basin) and southwestern (Campeche basin) quadrants. Basement elevation and hydrocarbon distribution are also diagonally symmetric. Highest basement elevations occur in the southeastern (Yucatan) and northwestern (Llano-San Marcos Arch) quadrants. Hydrocarbon distribution mimics salt distribution.We believe that these diagonal symmetries are a consequence of the nature of the rifting process. We envisage a simple-shear rift sequence in which the Gulf basin is fractured and fragmented by a series of northwest-southeast trending transfer faults. The transfer faults divide the lithosphere into segments characterized by different rates of extension, amounts of extension, and most importantly, directions of detachment dip.The principal transfer fault is the Brazos transfer fault (BTF). It parallels the eastern margin of the Llano Uplift-San Marcos Arch in the northern Gulf and may follow the Ticul fault in western Yucatan. The basal detachment surface in the segment northeast of the BTF dips southeast, whereas the detachment southwest of the BTF dips northwest. The Llano-San Marcos and Yucatan areas belong to paleo upper (or breakoff) plates, whereas major salt basins overlie subsided lower (or breakaway) plates.
INCISED VALLEYS IN THE BRENT GROUP OF NORTHWEST HUTTON FIELD, UK NORTH SEA: FILL CHARACTERISTICS, GEOMETRIES AND COMPARISON WITH OUTCROP ANALOGUES FROM THE BOOK CLIFFS, UTAH
Authors: FLINT STEPHEN , HOWELL JOHN , KNIGHT SIMON , TILBROOK ANDY 
Published: October 2019

ABSTRACT
The Middle Jurassic Brent Group of Northwest Hutton Field includes recently recognized incised valley systems in the Etive and Ness formations. These valleys were cut during relative sea-level falls and back-filled during subsequent rises. Valley-fills comprise mixed fluvial-tidal and purely fluvial rocks. Their grain size, orientation, and geometry contrast markedly with volumetrically greater highstand shoreface and delta mouth bar sheet sandstones. The valley-fills have significantly influenced production history of the field.
Published data from other Brent Group fields allows correlation of sequence boundaries semi-regionally. Incised valley-fills range from 1.5 to 15 km in width and appear to have been focused on the Northwest Hutton area through time. Similarly other Brent Group fields appear to have occupied interfluve positions at successive sequence boundary times. This observation reconciles historical conflicts over the presence of sequence boundaries in the Brent province, with some fields having only subtle expressions of these key regional surfaces. Comparison of Brent incised valleys with well exposed examples from the Book Cliffs, Utah increases confidence in valley-fill interpretation and allows prediction of likely ranges of geometry and fill type in undrilled areas. The Book Cliffs example also raises the issues of the nature and location of possible lowstand deposits in front of the Brent delta.
Produção e valorização do espaço urbano: o caso dos novos loteamentos de Alfenas-MG
Authors: Ribeiro Ariádina Aparecida Lelis 
Published: October 2019

Este trabalho apresenta um estudo da expansão urbana no município de Alfenas-MG através dos novos loteamentos horizontais e suas implicações sobre a estrutura socioespacial da cidade. Evidencia-se que o crescimento horizontal da cidade está sendo impulsionado por uma intensa especulação imobiliária, viabilizada pelo poder, acumulação e competitividade pelo espaço. Tal processo provoca alterações na paisagem urbana e rural e, afeta os valores das residências já instaladas próximas aos novos loteamentos, assim como também dos moradores e dificulta o acesso às terras das camadas de menor renda, contribuindo assim, para o aprofundamento da desigualdade socioespacial, da exclusão social e segregação dos bairros da cidade. Buscou-se através de pesquisas bibliográficas, trabalhos de campo realizados e consultas em sites IBGE, entre outros, mostrar que esses novos loteamentos se tratam de uma visível especulação e antecipação espacial, pois a cidade, por mais que é considerada como média, não possui porte e demanda para tais empreendimentos, assim como também não possui estruturas para atender novas demandas sociais. Além disso, é plausível de atenção para que não ocorra novos empreendimentos imobiliários e que sejam realizados estudos e um planejamento urbano mais coerente com os ensejos da população.Palavras-chave: Produção do espaço, especulação imobiliária, cidade média, segregação, acumulação.Abstract This research presents a study of urban expansion in the city of Alfenas-MG through the new horizontal subdivisions and their implications in the socio-spatial structure of the city. The horizontal growth of the city is being driven by intense real estate speculation, made feasible by the power, accumulation and competitiveness by the space. This process causes changes in the urban and rural landscape and affects the values of residences already installed in the vicinity of the new subdivisions, as well as of the residents and demanding access to the lands of the lower-income layers, thus contributing to the deepening of the socio-spatial conditions Inequality, Social exclusion and segregation of the city's neighborhoods. It was searched through bibliographical researches, field works and consultations in the IBGE, sites, among others, to show that these new subdivisions are a visible speculation and a spatial anticipation, since the city, although considered average, does not have size and demand By these companies, nor do they have the structures to meet new social demands. Besides, it is plausible to ensure that no new real estate developments occur and that studies and urban planning are conducted that are more consistent with the opportunities of the population.Keywords: Production of space, real estate speculation, middle-sized city, segregation, accumulation.
