    A card system is developed using BPCS (Business Planning and Control System) steganography, with electronic data imbedded in the card. Under the system, the visual recognition of the user and the mechanical verification of the card are carried out simultaneously, with the card rejecting any abuse. In fiscal 1998, a system was built by way of trial, constituted of technologies of encoding, decoding, and packaging data into an IC (integrated circuit) card. A photograph of the user's face is attached to the card, the card carries an 8KB IC memory device, and the device stores data of the photograph of the user's face etc. A password has to be inputted before any data may be taken out. A customized key is required to display the imbedded personal data and, for the restoration of the key data, the personal key known only to the owner and the company key that is kept by the card managing company need to be collated with each other. Multiple checking is available for the prevention of abuse, which include the collation of face photographs, collation with display by inputting the password, and request for the customized key to confirm the presence of authority to read the imbedded personal data.

    For the purpose of developing technology for supplying products with competitive power on the industry basis in terms of quality, cost and function, the R and D were conducted by grasping cultured skin/mucosa in a frame of products, and the FY 2000 results were reported. In the study of systematization of the culture of epithelial cell, automatic management of products using bar codes and automation in the culture medium exchange process using robot increased productivity and made the culture of high-quality epithelial cell possible. Further, it was confirmed that it was possible to introduce genes into the cultured cell in this system. In the study of improvement of the existing cultured skin, development of the low-cost transplantation carrier was made keeping characteristics of the medical instrument. Also developed was the packaging of cultured skin on the brittle carrier. In the developmental study of new cultured skin, the following were studied, and the useful knowledge/information were acquired: study of the transplantation using cultured skin/mucosa of base material composition type, study of the packaging, study of the cell detrimentality, etc. (NEDO)

Les paléoenvironnements mésozoïques et cénozoïques de quelques marges du bassin Ionien profond (Méditerranée orientale et plus particulièrement ceux de l'escarpement de Malte ont pu être reconstitués partiellement grâce à une étude biostratigraphique. Aux faciès de plate-forme du Trias et Lias inférieur-moyen succèdent, comme en Sicile, des séries pélagiques au Jurassique moyen et supérieur. Au Crétacé inférieur, lacunes ou érosions caractérisent la série de l'escarpement de Malte par opposition aux séries de plate-forme des monts de Médine. Dès l'Albien jusqu'au Miocène, la sédimentation est à dominance pélagique avec présence locale de dépôts circalittoraux et brèches à éléments de plate-forme (Maestrichtien, Eocène, Oligocène ou phénomènes d'érosion, voire hiatus (Cénomanien-Turonien.

Enfin, on notera un magmatisme important accompagnant des phénomènes de distension dès le Jurassique supérieur. The Escarmed 3 coring and dredging campaign in the Ionian Sea comes after a series of similar surveys by French and Italian vessels. They made it possible to partially reconstruct the Mesozoic and Cenozoic paleoenvironments of several margins of the deep Ionian basin (Eastern Mediterranean, especially those of the Malta escarpment, on the basis of biostratigraphic analysis. Whereas a shallow-water environment prevailed during the Triassic and the Lower to Middle Lias period, pelagic facies are observed in the Middle-Upper Jurassic series of this area, just as has been found in Sicily. During the Lower Cretaceous, gaps or erosions characterize the Malta Escarpment, whereas the Medina seamounts are subject to continuous shelf sedimentation. From the Albian up to the Miocene

    In the Republic of Kenya, problems are how to build bridges over small rivers, not big rivers, and what bridge types to choose for reduction in cost. Concrete bridges under the direct control of the Government construction office are 15m at the longest, and they are directly founded on the hard basement after a little excavation. In formulating construction plans, it is necessary to take climate into account, such that there is but a small amount of precipitation and that it concentrates in the rainy season. The first stage of bridge building involves the construction of low-cost structures which enable river-crossing except in the rainy season. This first-stage concept is worth deliberation when it is known that there are semiarid regions where river-crossing is prohibited due to high water levels in the rainy season but for approximately two weeks a year. In the second stage, permanent structures are required, serviceable even in the high water level season. In the third stage, it is necessary to construct bridges conforming to the road assuring excellent trafficability. For reduction in the cost of small bridge construction, drift types, culvert types, and temporary bridges like Bailey bridges are important choices. 2 refs., 12 figs.

    Fuji Electric has realized highly reliable and functional control systems by the dispersion type control system FOCUS, which uses the controller (ICS-2000) enjoying good reputation in controlling industrial plants for a long time and a personal computer with high windows operability, the former for controlling and the latter for MHI responsible for monitoring. The smelting process in a steel-making plant needs a highly reliable system for advanced control to ensure continuous operation. Fuji Electric delivered the FOCUS system to Kubota in 1998, as the smelting furnace instrumentation/control system for the cupola furnace. The system has been in service smoothly. Moreover, a total of four control systems have been delivered, 2 for steel-making furnaces and the other 2 for continuous casting. (NEDO)

    In this survey, studies for popularization and practical utilization of small and medium size geothermal binary cycle power systems which assesses low and medium temperature geothermal resources were conducted, and studies for development of the system to be introduced for practical use and for promotion of the popularization were made. A study was carried out of preconditions and various conditions of a demonstrative test plant (100kW class, 500kW class) in view of the initial cost of the actual plant, and an analysis was made of the power generation cost. Acceptability of the demonstrative test plant (100kW class) was examined to analyze problems on the introduction. A thermodynamic analysis was made of the output of geothermal binary cycle power generation. Analysis/evaluation of the results of the 100kW demonstrative test plant were carried out in view of the operation results of the plant of the same kind, and checks/reviews were conducted of performance and reliability of the system, equipment simplification, etc. Inspection of the system was made in the stage of design/manufacture of the 500kW demonstrative test plant. Concerning the spread/expansion of the system, studied were multiple stage geothermal utilization and PR promotion method. 14 refs., 62 figs., 55 tabs.

    Palaeostresses and deformation axis reconstruction related to the intracontinental High-Atlas uplift evidences two shortening phases from Upper Cretaceous to Quaternary. The first compression is oriented N20-30°E and is Maastrichtian to Oligocene age; the second one, oriented N120-160°E, is syn-Mio-Pliocene. Tectonic inversion of the lateral to compressive Jurassic regime is contemporaneous with the beginning of Africa and Europe collision. Rotation of the Mio-Pliocene shortening orientation could be linked to the change of the convergence direction between the Africa and Europe plates. To cite this article: M. Amrhar, C. R.

    The above-named effort aims to work out modification plans and to predict their energy saving, energy substituting, and greenhouse gas reduction effects, and thereby to scout out a project which will effectively utilize flexibility-ensuring 'joint implementation' for the attainment of greenhouse gas reduction levels defined at COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change). The results of assessment of this project based on the outcome of the survey show that (1) there is necessity for the project and that the presence of needs to be urgently satisfied is clear, that (2) energy saving, energy substituting, and greenhouse gas reduction effects are proved to exist and that the project is therefore an appropriate candidate for an activity to be implemented jointly, that (3) Russian agencies concerned are strongly interested in the project and that a sufficiently cooperative system will be available toward implementation, and that (4) there is an extremely large room for energy saving in the district heating oriented heat supply business in Russia and that probabilities are quite high that natural gas-fired turbine cogeneration plants capable of improving overall energy efficiency will enjoy extensive diffusion.

  16. Evolution of the Northeastern Arabian Plate Margin and Shelf: Hydrocarbon Habitat and Conceptual Future Potential L'évolution géologique de la plate-forme arabe et de sa marge : répartition des hydrocarbures et concepts pour son potentiel futur

    Full Text Available About 98% of the huge recoverable hydrocarbon reserves of the Arabian Plate are concentrated in the Northeastern Margin Shelf extending from NW Iraq through the Gulf to Central Oman. The plate tectonic evolution of this region is reviewed as background for its enormous hydrocarbon productivity. This is intimately linked to a near-continuous passive margin history and gentle subsidence of an extraordinarily wide epeiric shelf, which allowed repeated regional development of source rocks in large intra-shelf basins frequently in optimal juxtapositional relationships with good regional reservoirs and seals; these events are discussed. Although currently reported reserve figures relate to Mesozoic and Tertiary reservoirs, it is concluded that several pre-Mesozoic regional sources have generated enormous volumes of hydrocarbons, the bulk of which still await discovery in up-dip Paleozoic reservoirs, and that future ultimate recoverable reserves could conceivably double. Près de 98 % des énormes réserves récupérables d'hydrocarbures de la plaque arabique sont concentrés dans la marge nord-est qui s'étend du nord-ouest de l'Irak au centre d'Oman, à travers le Golfe. L'auteur passe en revue l'évolution tectonique de cette région, origine de son énorme productivité pétrolière. La passivité presque continue de cette marge, combinée à l'affaissement progressif d'un plateau épicontinental particulièrement large, a permis le développement local répété de roches mères, au sein du plateau, dans de vastes bassins bénéficiant souvent d'une juxtaposition optimale avec les roches réservoir et roche-couvertures. L'article étudie ces évènements. Si les réserves actuellement prises en compte sont essentiellement d'origine mésozoïque et tertiaire, l'auteur conclut que de nombreuses sources régionales pré-mésozoïques ont généré d'énormes volumes d'hydrocarbures, dont la majeur partie reste à découvrir dans des réservoirs pal

    Full Text Available Background: Lost to follow-up (LTFU is a major challenge that hinders the success of antiretroviral treatment (ART.Objective: To identify factors conducted to a low LTFU rate.Methods: We conducted a two-part descriptive and quantitative study. Part 1 comprised interviews with clinic staff to determine their perspectives on LTFU and to establish the clinic’s follow-up procedures for patients on ART. Part 2 of the study was a retrospective review of clinic and patient records. LTFU patients were identified and those with contact details were contacted for telephonic interview to determine if they were still on ART and/or their reasons for becoming LTFU.Results: A low LTFU rate (7.9%; N = 683 was identified. Work-related stress, and lack of transport and funds were reported reasons for LTFU. Monthly visits, non-adherent defaulters and LTFU patients were tracked by an electronic system (SOZO. Factors contributing to high rates of retention in care were: location of the clinic in the inner city, thus in close proximity to patients’ homes or work; clinic operating on Saturdays, which was convenient for patients who could not attend during the week; an appointment/booking system that was in place and strictly adhered to; a reminder SMS being sent out the day before an appointment; individual counselling sessions at each visit and referrals where necessary; and a stable staff complement and support group at the clinic.Conclusion: Achieving a low LTFU rate is possible by having a patient-centred approach and monitoring systems in place.

    Full Text Available On présente ici les principaux résultats de l'étude géochimique réalisée, dans le bassin de Paris, à partir des déblais et des carottes provenant de 100 sondages pétroliers ou miniers, et des huiles prélevées dans les réservoirs du Mésozoïque (Trias, Bathonien supérieur, Néocomien. Les différentes méthodes géochimiques utilisées sont la pyrolyse, particulièrement bien adaptée à l'étude des nombreux échantillons de déblais recueillis, la chromatographie en phase gazeuse pour l'analyse détaillée des huiles et des extraits de roche, la spectrométrie de masse pour l'étude des biomarqueurs. Les époques principales de formation de l'huile et du gaz ont été déterminées par simulation sur ordinateur d'un modèle mathématique de genèse des hydrocarbures. Les méthodes de pyrolyse ont permis de dresser des logs géochimiques des forages étudiés et de déterminer, par le calcul, les paramètres de pyrolyse initiaux des roches-mères, avant leur enfouissement. On a pu ainsi établir, dans le périmètre étudié, des cartes de carbone organique initial, de potentiels pétroliers totaux et de quantités d'HC migrés. L'ensemble de ces résultats montre que les roches-mères de la grande majorité des huiles du Mésozoïque sont situées dans le Lias, s'échelonnant depuis le Toarcien jusqu'à l'Hettangien et que les meilleures zones de potentiel pétrolier du Bassin sont localisées à l'emplacement des régions de forte subsidence à l'époque du Lias. L'étude détaillée des hydrocarbures et celle des biomarqueurs ne permettent pas de distinguer les différentes huiles entre elles, quelle que soit leur profondeur, ni de leur attribuer une origine précise à partir des différents niveaux du Lias. Les cartes de migration mettent en évidence des déplacements latéraux des hydrocarbures dans certaines roches-mères (cas du Toarcien inférieur. Elles montrent aussi un déficit important en hydrocarbures à la base du

En effet, en plus du facteur lithologique (parois calcaires imposantes, il y a un facteur tectonique essentiel : l'évolution d'une marge continentale mésozoïque réactivée par des phases tectoniques plus récentes, essentiellement Miocène et Plio-Quaternaire. C'est cette originalité qui distingue l'escarpement de Malte et les monts de Médine des autres marges méditerranéennes occidentales et qui permet leur comparaison avec d'autres marges continentales, atlantiques par exemple. The Comité d'Etudes Pétrolières Marines (CEPM and the Centre National pour I'Exploitation des Océans (CNEXO have carried out a series of subsea surveys of Ionian escarpments to define their origin, age and evolution. The results given here concern the Malta escarpment, the Alfeo and Medina seamounts west and southwest of the deep Ionian basin. They include bathymetric data in the form of a 1:100,000th map accompanying the text, a morphological analysis of reliefs, stratigraphic determinations performed on samples gathered by dredging, coring or diving, a structural analysis from seismic-reflection profiles and dives, and a study of subsidence since the Upper Triassic from actual boreholes drilled in the Maltese shelf and fictitious boreholes on the edge of the Malta escarpment. The conclusions bring out:(a the existence of calcareous platform series of early Jurassic age for the Malta escarpment and the Alfeo seamount and of early Cretaceous age for the Medina seamounts;(b a major paleogeographic change starting in the late Jurassic for the Malta escarpment and in the Albian for the Medina seamounts;(c the development of condensed series dating from this paleogeographic change and the presence of constant erosion until the Present, an erosion in which the various processes have numerous consequences on the sedimentation of such reliefs;(d four main

Les grès de faible perméabilité se trouvent surtout parmi les couches permiennes (Rotliegend aux Pays-Bas et dans le nord de l’Allemagne, mais aussi dans les couches du Carbonifère supérieur. La production est déjà active dans quelques-uns de ces réservoirs. Pour l’avenir, le développement dépendra principalement de l’amélioration de la compréhension du gaz en place et de la distribution régionale de la porosité et la perméabilité qui, d’ailleurs, dépendent du faciès lithologique et la diagénèse. La recherche de gaz dans les roches argileuses, par contre, vient juste de commencer. Les roches argileuses mésozoïques dans le sud du bassin de Basse-Saxe (Lower Saxony Basin sont des objets d’exploration prioritaire à cause de leur épaisseur, de leur maturité et de leur teneur en matière organique. Mais il existe d’autres séries intéressantes dans le carbonifère inférieur et des couches plus anciennes. Actuellement, un projet de recherche international vise à acquérir des données géologiques sur ces systèmes. La recherche du gaz de houille (CBM a commencé dans la bassin de la Ruhr il y a une vingtaine d’années, mais avec un succès très limité à cause de faibles débits de gaz. En revanche, le captage de grisou des mines de charbon abandonnées a fourni de considérables quantités de gaz. De par la multitude des filons houillers et des conditions de maturité et de teneurs en gaz favorables, il existe dans cette région un potentiel considérable de gaz de houille.

    Full Text Available Des études de terrain détaillées ont été reprises récemment par l'Institut Français du Pétrole (IFP et l'Ecole Nationale Supérieure du Pétrole et des Moteurs (ENSPM dans la partie occidentale du bassin nummulitique des Alpes du Sud afin d'aider les interprétations de données sismiques. Ces études soulignent l'importance de la tectonique en distension qui a affecté le bassin durant la sédimentation; elles remettent en question l'interprétation géodynamique de ce bassin considéré classiquement comme une avant-fosse de la chaîne alpine en cours de formation. Sur un substratum mésozoïque structuré par la phase pyrénéo-provençale, la transgression nummulitique envahit dès le Lutétien les parties les plus basses du bassin situé à l'Est dans une zone qui sera oblitérée au Mio-Pliocène par l'accident pennique. Elle s'étend progressivement vers l'Ouest durant l'Eocène supérieur. Dans le même temps une phase de distension E-O bien visible le long des failles du Var et en bordure du Pelvoux se traduit par le compartimentage des bordures du bassin et par des jeux en blocs basculés durant la sédimentation. Dans les calcaires qui débutent la série marine, ces jeux sont responsables du passage rapide de faciès de plate-forme à des faciès resédimentés sur les pentes, puis à une sédimentation gravitaire de plus en plus réduite en s'éloignant des bordures. Les marnes sus-jacentes correspondent à des dépôts de talus qui soulignent la topographie héritée. Le passage à la sédimentation turbiditique des grès d'Annot s. l. , est corrélé avec le début d'une activité de rift sur le bloc corso-sarde et le changement climatique qui intervient à cette époque. Le dépôt de ces grès dont l'épaisseur maximale observée est de 1 200 m correspond à une phase de remplissage, avec des onlaps bien marqués soulignant les paléopentes. La distension E-O se poursuit durant la sédimentation des grès mais elle s

    'unification des deux ex-Yemen, a incité de nombreuses compagnies pétrolières à se lancer dans la course à l'exploration, à exécuter des études sismiques approfondies et à entreprendre des campagnes de forage intensives en de nombreux points du pays. Il en a résulté un accroissement rapide du nombre des nouvelles données géologiques concernant le sous-sol et une perception de plus en plus claire de la distribution, de l'orientation et du moment de formation des principaux bassins. Il convient de noter, toutefois, qu'aucune synthèse de l'ensemble des résultats n'a encore été entreprise, chaque compagnie ne s'intéressant qu'à sa concession et aux zones avoisinantes. Des études récentes portant sur l'analyse, la comparaison et la synthèse de la masse des nouvelles données stratigraphiques disponibles, dans le cadre de la standardisation de la nomenclature lithostratigraphique utilisée au Yemen et de sa mise en conformité avec les normes et règles internationales ont demandé obligatoirement la mise en place d'un cadre structurel général permettant une corrélation stratigraphique entre les bassins et à l'intérieur de ces derniers. L'objet du présent article est donc de présenter la nouvelle carte des bassins sédimentaires et des redressements qui les séparent. La formation des principaux bassins mésozoïques résulte de l'extension et de l'effondrement du système jurassique récent qui ont entraîné, essentiellement, la réjuvénation de l'ancienne faille de Najd orientée nord-ouest/sud-est suivie de l'apparition d'un rejet horizontal. Les bassins du Tertiaire sont nés de la séparation de l'Arabie et de l'Afrique au Néogène le long des axes du golfe d'Aden et de la mer Rouge. Les principaux redressements remontent à la même époque, le plus ancien et le plus persistant étant la chaîne de l'Hadhramaout. Toute l'activité tectonique est liée à la fragmentation et à l'éclatement du Gondwanan, depuis la fermeture initiale du pal
