Résumé : This cigar-making industry has contributed materially to the development and growth of Tampa during the last five years, and it promises much greater benefit in the future. It was in October, 1885, that Martinez Ybor & Co., who began manufacturing in Havana in 1854, and afterward put up a large factory in Key West, came to Tampa to investigate the resources and advantages offered for cigar-making. They soon afterward purchased forty acres of land in the Fourth Ward, cleared it of the pines, wild-oats and gophers, and built a factory, a large boarding-house or hotel, and several small cottages for the workmen whom they brought from Key West and Havana. The venture proved a success from the start and improvements were added. The original factory, a wooden structure, is now the opera house, and a large brick factory has succeeded the first one, where the daily output of the 450 cigar makers employed is40,000 to 50,000 cigars. Then came Sanchez & Haya, Emilio Pons, and others, and all declare that they are doing an excellent business.

Résumé : A Inner lid label for one of the earliest factories in Ybor City.
When Vicente Martínez Ybor departed Spain for Cuba in 1832, the enterprising fourteen-year-old quickly became involved in the emerging cigar industry. By 1853, he had consolidated small workshop production of cigars into a large Havana factory. His early brand El Principe de Gales, remained his most popular brand of cigars throughout his manufacturing career which extended to Key West, New York City and Ybor City. As a tribute to the namesake of Ybor City, the V. Martínez Ybor's Sons Company produced a brand of cigars in honor of their father in 1902, six years after his death.

Résumé : La manufacture de la soie est une industrie qui fut présente en France, mais aussi dans les colonies durant la moitié du xviie siècle. Elle représentait le luxe dans le secteur textile. Pourtant, il n’y a pas d’études sur la question. Elle est oubliée au profit de la culture du sucre, davantage étudiée. Cet article permet de comprendre les efforts faits afin de l’implanter dans les Antilles. La Métropole voulait développer une alternative au sucre, tandis que les colons voulaient rester dans l’économie servile et rentable avec le système des habitations et des raffineries. La question de la dépendance est présente avec des opinions très différentes.
The manufacture of silk, is an industry that was present in France and also in the colonies during the mid-seventeenth century. It was the luxury in the textile sector. However, there are no studies on the issue. It’s forgotten in favor of the cultivation of sugar, which is present in the studies. This article provides an understanding of the efforts to promote the Caribbean. France wanted to develop an alternative to sugar, while the settlers wanted to stay in the profitable slave economy with system habitations and refineries. The dependence is present with very different opinions.

Résumé : International audience
BACKGROUND: Phthalic acid esters are widely used in the manufacture of plastics. Numerous studies have shown that these phthalates impair testicular testosterone production in the rat. However, the scarce and contradictory data concerning humans have cast doubt over whether these compounds are also anti-androgenic in man. We therefore investigated the direct effects of di-(2-ethylhexyl) phthalate (DEHP) and mono-(2-ethylhexyl) phthalate (MEHP) on organo-cultured adult human testis and a human cell line. METHODS: Adult human testis explants or NCI-H295R adrenocortical human cells were cultured with DEHP or MEHP. The effects of ketoconazole, used as a reference molecule, were also assessed. RESULTS: In both models, DEHP and MEHP significantly inhibited testosterone production. The effects of both phthalates appeared to be specific for steroidogenesis, as INSL3 production by Leydig cells was not altered. Furthermore, the phthalates of interest had no effect on inhibin B production by Sertoli cells or on germ cell apoptosis. As only a small fraction of the phthalates added was found in the testis explants, and as these compounds were found to be metabolized, we estimate that the anti-androgenic effects observed occurred at concentrations of phthalates that are of the same order of magnitude as exposures reported in the literature for men. CONCLUSIONS: We provide the first evidence that DEHP and MEHP can inhibit testosterone production in the adult human testis. This is consistent with recent epidemiological findings of an inverse correlation between exposure to MEHP and testosterone concentrations.

Résumé : Les zones franches sont des espaces de dérogations législative et sociale. Elles sont spécialisées dans des activités manufacturières où dominent majoritairement l’assemblage textile et minoritairement l’électronique et les services. Elles se développent dans la région Caraïbe, au cours des décennies 1980 et 1990, dans un contexte économique favorable. Dans cet article nous nous interrogeons sur les causes économiques de leur émergence. Ces espaces industriels sont difficiles à définir tant les activités présentes sont diverses et évolutives dans le temps. C’est pour cette raison que dans la première partie nous traitons de la complexité de cette notion. Ensuite, nous verrons les causes économiques de leur émergence. Le semi-échec des politiques d’industrialisation par substitution des importations oriente l’industrialisation vers l’extraversion. Les principes libéraux appliqués à Puerto-Rico servent à encadrer les industries exportatrices. Les plans d’ajustement du FMI pour réguler le problème de l’endettement ont servi de catalyseur aux exportations des biens manufacturés. Parallèlement, les accords commerciaux du Caribbean Basin Initiative (CBI) avec la puissance étasunienne ont encadré leur essor. Enfin, nous montrerons les modalités de leur implantation dans la Caraïbe, modalités qui induisent des différences géographiques entre des îles entièrement franches et celles où les zones franches sont des enclaves économiques. L’étude de ces dernières en République dominicaine permet de mettre en exergue leur expansion spatiale.
The free zones are spaces of social and legislative exemptions. They are specialized in manufacturing activities dominated mainly by the textile assembly. They develop in the Caribbean during decades 1980s and 1990s, in a favourable economic environment. In this article we question the economic causes of their emergence. These industrial areas are difficult to define as these activities are diverse and evolving over time. For this reason in the first part we deal with the complexity of the concept. Then we will see the economic causes of their emergence. The semi-failed policies of industrialization by import substitution industrialization oriented toward the extrovert. The IMF adjustment plans to regulate the problem of indebtedness has been a catalyst for exports of manufactured goods. Meanwhile, the trade agreements of the Caribbean Basin Initiative (CBI) with the U.S.A. supervised their development. Finally, we show how their presence in the Caribbean, conditions that lead to geographical differences between completely free zone islands and those where the free zones are economic enclaves. The recent study in the Dominican Republic will highlight their spatial expansion.

Résumé : International audience
A set of synthetic aggregates, containing mixtures of calcite and muscovite, were compacted with varying uniaxial loads ranging from 20 MPa up to 400 MPa. Their elastic properties have been measured using compressional and shear waves in confining hydrostatic pressures up to 475 MPa. Measured seismic velocities are shown to depend on 1) the ratio of calcite to muscovite, 2) the uniaxial load used during sample manufacturing, and 3) the porosity amount prior to velocity measurements. The matrix framework may also affect the seismic velocities, but this effect is not easily quantifiable. In general, measured seismic velocities decrease with increasing muscovite content and porosity. Elastic properties have been calculated based on texture measurements, which were obtained by neutron diffraction. The calculated velocities are based on the calcite and muscovite single crystal elastic tensors, their orientation distribution functions, and their modal fractions. A large discrepancy is apparent between calculated and measured velocities, where the former always overestimate the actual velocities. Shear waves display less of a difference between calculated and measured values, than do compressional waves, indicating that waves propagating by shearing are less affected by sample porosity and matrix framework. A better agreement between measured and calculated seismic velocities arises when the initial porosity is taken into account, using a differential effective medium model. Seismic anisotropy is evident from both measured and calculated velocities, and is low for samples containing pure calcite, but becomes prominent as the muscovite concentration increases. The intensity of anisotropy further depends on the uniaxial load used during sample compaction and the initial porosity.

Résumé : International audience
Given the clinical success of commercial amphotericin B lipid products, investigators have begun making generic formulations of liposomal amphotericin B. Generic medicines are an attractive approach to help decrease the cost and accessibility to healthcare, provided that appropriate studies are performed to ensure bioequivalence with the parent product. This is of particular concern for liposomal drugs such as amphotericin B where liposomes are used as a carrier system to reduce the toxicity of the active agent. A favorable therapeutic profile for this form of the drug has to include the proper chemical composition along with strictly controlled manufacturing processes. Studies have shown that a comparison of liposomal amphotericin B products with different or the same chemical compositions, using different methods of production, will vary in size, and have significantly dissimilar in vitro and in vivo toxicities along with reduced efficacy. These results underscore the importance of establishing appropriate bioequivalence testing for liposome products to ensure uniformity of their therapeutic index

Résumé : Une étude de faisabilité de poutres en bois lamellé-collé a été menée en Guyane Française en utilisant les essences locales. Le but est de déterminer les paramètres de collage assurant la bonne résistance mécanique des assemblages par lamellation et par aboutage, nécessaires à la fabrication de poutres en bois lamellé-collé en climat tropical. Trois essences de bois abondantes de différentes densités ont été sélectionnées. Les adhésifs de types Mélamine-Urée-Formol et Résorcinol-Phénol-Formol ont été utilisées. Les paramètres de collage considérés sont : le grammage, le temps d’assemblage fermé et la pression.En utilisant les normes Européennes, plusieurs campagnes de tests ont été conduites sur des échantillons normalisés. Concernant le collage par lamellation, des tests élémentaires de délamination et de cisaillement des joints de colle ont été réalisés. Le test de délamination consiste en deux cycles d’immersion dans l’eau sous pression et de séchage, il induit de sévères variations d’humidité du bois susceptibles de créer des ouvertures des joints de colles. Le collage par aboutage est réalisé sur des poutres normalisées aboutées. Les entures sont obtenues grâce à un outillage standard communément utilisé pour les résineux. Les résultats ont mis en évidence l’influence des propriétés du bois et des paramètres de collage sur la résistance du joint et la résistance mécanique du produit. En effet, les paramètres du bois, tels que la densité, la rétractibilité et l’imprégnation, ont une forte influence sur le collage, en particulier sur la pression et le grammage nécessaires à la production d’un produit commercialisable. Il apparait qu’un bois de densité moyenne et poreux nécessite un grammage et une pression élevés comparé à un bois de densité élevée qui nécessite des valeurs moindres. Aussi, l’influence d’autres paramètres de fabrication, tels que le rabotage, l’encollage double face et simple face ainsi que l’épaisseur des lamelles, a été établie. Par contre il semblerait que le matériel communément utilisé pour l’aboutage des résineux n’est pas adapté aux feuillus tropicaux. En final, des paramètres de collage ont été validés pour la fabrication de lamellé-collé endémique en Guyane Française et une étude du coût de production d’une poutre lamellé-collé standard a identifié les conditions économiques d’une fabrication en Guyane Française.
A feasibility study of glued-laminated timber beams was carried out in French Guiana using local wood species. The aim of the study was to evaluate the gluing parameters that could ensure good mechanical properties for the manufactured glued-laminated beams in tropical climates. Three abundant wood species with different specific gravity were selected for the study. Melamine-Urea-Formaldehyde and Resorcinol-Phenol-Formaldehyde resins were used for gluing. The three gluing parameters considered are: adhesive spread rate, closing assembly time and gluing pressure.Using European standards, several laboratory tests were performed on normalized samples. The evaluation of a successful lamella’s gluing was done by using elementary tests of delamination and shearing. A delamination test consists of two cycles of water immersion at high pressure and drying which induces severe hygroscopic variation in wood thus causing joints opening. The finger-joints are made using a standard tool usually used for cutting softwoods. The performed tests revealed the influence of wood properties and the gluing parameters on the joint resistance and the mechanical properties of the product. Results show that wood properties such as specific gravity, shrinkage coefficient, and permeation, have a high degree of influence on the gluing step especially on the gluing pressure and on the adhesive spread rate needed to produce a commercial product. Furthermore, wood with medium specific gravity needs more adhesive and more pressure than the one with high specific gravity. Additionally, the effects of other manufacturing parameters, such as planning, double or simple side glue spreading and lamellae thicknesses, on the glue joint resistance were demonstrated. Finally, the common tools used for softwoods are not adapted to making the finger joints with tropical hardwoods.In conclusion, optimal gluing parameters for manufacturing glued-laminated timber beams in French Guiana were established and an economical study using standard glued-laminated timber beams revealed the economic conditions under which a successful manufacturing of these local beams can be implemented in French Guiana.

Résumé : This document shows several of the main findings of the research work in the towns of San Juan de los Lagos and Santa Ana de Guadalupe, Jalostotitlán, Mexico, on the occasion of knowing the impact it has had the policy used by the Ministry of Tourism, regarding the promotion of religious tourism in both populations as a source for economic development.Among the findings are that the project whose intent is to develop a similar route to that of the "Camino de Santiago" in Spain, and include both populations is often unknown to visitors to these religious sites.Another important result concerns the data were limited marketing of products manufactured locally or regionally. This prevents the economic benefits of religious tourism that visits this population, have very little benefit to people nearby.

Résumé : International audience
To study the associations between occupation, industry and prostate cancer risk in Guadeloupe, a high incidence area. Incident cases of prostate cancer (707 cases) and 722 population controls were included. Information on lifetime occupational history and other potential risk factors was collected by interview. Logistic regression was used to estimate adjusted odds-ratios (OR) and their 95% confidence intervals (CI). A significantly decreased risk was observed in farmers (OR=0.5; CI 0.4-0.7), whereas marginally elevated ORs were found for farm workers, especially in sugarcane and banana farming. Banana plantation workers had been exposed to chlordecone, an estrogenic insecticide previously found to be associated with prostate cancer risk in this population. Significantly increased risks of prostate cancer were found in stock clerks (OR=2.7; CI 1.0-7.2), fishermen (OR=2.0; CI 1.0-4.0), mail distribution clerks (OR=7.7; CI 1.7-34.4) and electricians employed for more than 20 years (OR=4.0; CI 1.0-15.8), as well as in public administration (OR=1.8; CI 1.2-2.9), retail trade (OR=2.6; CI 1.1-6.0) and manufacture of food products (OR=2.0; CI 1.1-3.9), particularly sugar (OR=13.2; IC 1.6-108). Non-significantly elevated ORs were also seen for construction workers and transport equipment operators. Although the overall findings suggest that occupational factors have only a limited role in prostate cancer aetiology, elevated risks of prostate cancer were found in several occupations or industries. Exposure to pesticides, solvents, traffic-related air pollution, low physical activity, whole-body vibration may explain some of these increased risks.

Résumé : The maritime economy includes the activities linked to the sea, namely: - Marine resource extraction: living resources and marine minerals, - Exploitation of marine space and of physical properties of marine waters (energy plants - using marine water as a heat sink, marine renewable energies, submarine cable laying, - maritime and coastal construction and public works, maritime transport, Navy), - Exploitation of seascapes (tourism, leisure, boating), - Resource processing (of living resources and oil & gas) - Manufacturing and service industries supplying the above exploitation activities: shipbuilding, ship repair and boat building and their suppliers, oil and gas services, financial services, - Public services: defence; State intervention at sea and public services to maritime activities and to seafarers; public and private activities contributing to the protection of marine and coastal environment; and public research. Since 1997, the French Marine Economic Data report, published by Ifremer, includes a set of key sectoral indicators used to value the economic significance of the French marine-related activities in terms of production and jobs, their role in the national economy, their weight in international competition and the importance of non-market public services. The analysis of the marine sectors is carried out mainly at national scale but regional indicators are also presented when they are available. The European dimension of the activities is also taken into account.

Résumé : Our method for the simultaneous determination of the four natural Ra isotopes (Ra-226, Ra-228, Ra-224 and Ra-223) in thermal waters involves a separation of Ra on a selective filter (3 M EMPORE (TM) Radium Rad disk), and a single counting using a broad-energy HPGe detector (BE Ge manufactured by CANBERRA (TM)). The calculation of Ra-223 and (228)a activities requires interference and cascade summing corrections. The Ra-226 activities in CO2-rich thermal waters of the Lodeve Basin (South of France) range from 530 to 2240 mBq/l. The low (Ra-228/Ra-226) activity ratios (0.19-0.29) suggest that Ra is mostly derived from the aquifer carbonates. The short-lived Ra-224 and Ra-223 are probably added to the water through recoil or desorption processes from Th-enriched coatings on the fracture walls.

We propose new methods for evaluating the spatial distribution of firms. To assess whether firms are concentrated or dispersed, economists have tradi-tionally used indices that analyse the heterogeneity of a spatial structure at a single geographic level. We introduce distance-based methods, Besag's L function (derived from Ripley's K function) and Diggle and Chetwynd's D function to describe simultaneously spatial distribution at different geographical scales. Our empirical applications consider the distribution of French manufacturing firms in the Paris area and in France generally. For some geographic levels, results show significant concentration or dispersion of firms according to their sector of activity.

Résumé : Monitoring crustal deformation during the interseismic phase when searching for earth transients requires precise instruments able to operate for very long periods. The ANR-LINES project aimed to develop three new instruments: a single-axis seismometer, a hydrostatic long base tiltmeter and a borehole pendulum tiltmeter. These three instruments benefit of an extrinsic Fabry-Pérot interferometer (EFFPI) with long optic fibers for displacement detections. Their mechanical architectures and their disposal of long fibers help these newly manufactured geophysical instruments complete their goals. The first objective of this study is to propose appropriate methods for estimating the phase of the optical path in the Fabry-Pérot cavities. A modulation of the laser diode current, followed by a homodyne demodulation of the interference signal and a Kalman filter, allow determining the phase in real time. The results are convincingwhile taking short periods measurements but require additional solutions for protection against environmental phenomena variations. The EFFPI sensor integrated in the LINES borehole tiltmeter gives it the opportunity to establish a differential measurement of the bob's oscillation thanks to three Fabry-Perot cavities. The LINES seismometer also uses the EFFPI displacement sensor to measure its coil's displacement. A description of the two instruments' mechanical structures and an analysis of the detected phenomena (slow movements, tides, earthquakes, microseisms . . . ) are part of this thesis.
Le suivi de la déformation de la croûte terrestre durant la phase intersismique pour la recherche des transitoires nécessite des instruments précis capables d'opérer pour de très longues durées. Le projet ANR-LINES a visé le développement de trois nouveaux instruments : un sismomètre mono-axial, un inclinomètre hydrostatique à longue base et un inclinomètre de forage pendulaire. Ces trois instruments profitent d'un capteur interférométrique de déplacement à longues fibres optiques du type Fabry-Pérot Extrinsèque (EFFPI). Leurs architectures mécaniques et l'utilisation de longues fibres permettent à ces instruments géophysiques nouvellement fabriqués d'atteindre les objectifs fixés. Le premier objectif de cette étude est de proposer des méthodes adaptées à l'estimation de la phase du chemin optique dans les cavités Fabry-Pérot. Une modulation du courant de la diode laser, suivie par une démodulation homodyne du signal d'interférence et un filtre de Kalman permettent de déterminer la phase en temps réel. Les résultats sont convaincants pour des mesures de courtes durées mais exigent des solutions complémentaires pour se prémunir des effets de la variation des phénomènes environnementaux. Le capteur EFFPI intégré dans l'inclinomètre de forage LINES lui offre l'opportunité d'établir une mesure différentielle de l'oscillation de la masselotte pendulée grâce à trois cavités Fabry-Pérot. Le sismomètre LINES utilise lui aussi le capteur de déplacement EFFPI pour la mesure du déplacement de sa bobine. Une description de l'architecture mécanique de ces instruments et une analyse des phénomènes détectés (mouvements lents, marées, séismes, microséismes . . . ) font partie de cette thèse.
