AbstractOver the past decades, the development of fibre optic cables, which pass light waves carrying data guided by total internal reflection, has led to advances in high-speed and long-distance communication, large data transmission, optical imaging, and sensing applications. Thus far, fibre optic sensors (FOSs) have primarily been employed in engineering, biomedicine, and basic sciences, with few reports of their usage in geophysics as point and distributed sensors. This work aimed at reviewing the studies on the use of FOSs in geophysical applications with their fundamental principles and technological improvements. FOSs based on Rayleigh, Brillouin, and Raman scatterings and fibre Bragg grating sensors are reviewed based on their sensing performance comprising sensing range, spatial resolution, and measurement parameters. The recent progress in applying distributed FOSs to detect acoustic, temperature, pressure, and strain changes, as either single or multiple parameters simultaneously on surface and borehole survey environments with their cable deployment techniques, has been systematically reviewed. Despite the development of fibre optic sensor technology and corresponding experimental reports of applications in geophysics, there have not been attempts to summarise and synthesise fibre optic methods for prospecting as a comprehensive and modern branch of geophysics. Therefore, this paper outlines the fibre optic prospecting methods, with an emphasis on their advantages, as a guide for the geophysical community. The potential of the new outlined fibre optic prospecting methods to revolutionise conventional geophysical approaches is discussed. Finally, the future challenges and limitations of the new prospecting methods for geophysical applications are elucidated.

The Lushi gold polymetallic ore-concentration area, located in the southern margin of North China Craton, is an important polymetallic ore district in the Qinling metallogenic belt. The Jianbeigou gold deposit is an important quartz vein type gold deposit in this district. In order to reveal the geological structure of the Jianbeigou gold deposit to guide deep prospecting, the EH4 conductivity image system was used in the Jianbeigou area. The sections obtained by the audio magnetotellurics method (AMT) indicate that the steeply dipping low resistivity zone in the area has a good corresponding relationship with the location of the known shallow ore bodies, and an extension in the deep. The low resistivity anomaly zone obtained by the inversion results are well correlated with the gold mineralization zone of the ore bodies, indicating good deep prospecting and exploration potential in this area. Based on geological and geophysical evidences, this paper inferred the possible occurrence location and depth range of the buried ore bodies. The AMT survey results reflect good exploration potential of the mining area and provide a geophysical basis for deep prospecting.

This study aimed to understand the social environment of groundnut production in Burkina Faso. The prospecting was carried out in three regions of Burkina Faso, namely the Central-East, the Central-North, and the Central-West Regions. Data were collected through direct observations and individual interviews using a questionnaire guide. At the end of this study, five (05) local ecotypes were collected which varied according to the ethnic group. These were Mayoro, zampou, dalga in Bissa ethnic group and Balolé, Wobgo in Mooré ethnic group. It appeared that groundnuts are mainly grown by women in small areas and these local ecotypes are disappearing progressively in favour of improved varieties developed by INERA (SH470P, QH243C). Research efforts for an agro-morphological and molecular genetic characterization of local varieties are necessary to facilitate their conservation.

The Hetaoping ore district in Baoshan City, Yunnan Province, is one of the major localities of Pb-Zn polymetallic skarn deposits in China, where geophysical and geochemical surveys play an important role in exploring Pb-Zn polymetallic mineral resources. Based on the exploration and prospecting carried out at the periphery of the Hetaoping Pb-Zn polymetallic deposit, this study proposed an aero-ground joint exploration method to determine the metallogenic model of distal skarns in the Hetaoping ore district, achieving ideal prospecting results. The steps of this method are as follows. First, the locations of ore-induced anomalies were determined using high-amplitude aeromagnetic anomalies. Then, the ore-induced anomalies were determined to be anomalies of Pb-Zn polymetallic deposits through geochemical surveys of soil samples and ground geophysical surveys. Based on these data, a quantitative analysis and metallogenic potential assessment of ore bodies and their surrounding rocks were conducted using the interactive 2.5D magnetic inversion. In addition, the 3D inversion of regional gravity data was also performed in order to determine the spatial location of the deep magma chamber. Accordingly, the metallogenic geological process in this area was analyzed by determining the spatial morphology of the deep magma chamber, and a prospecting model of the Pb-Zn polymetallic deposits was finally built. The results show that the aero-ground joint exploration method, which first conducts a rapid scanning survey using the aeromagnetic method and then locates, distinguishes, and assesses significant aeromagnetic anomalies by combining comprehensive verification means such as ground geophysical, geochemical, and geological surveys, is efficient and economical. This study will guide regional metallogenic research and the exploration and prospecting of Pb-Zn polymetallic deposits.

ABSTRACT. Multisource spatial data integration represents a common tool in mineral prospecting, especially with the advent of Geographic Information Systems(GIS), which allow manipulation, interpretation, analysis, integration and modelling of spatial data. The Nova Brasilˆandia Metasedimentary Belt (NBMB), located in SWAmazonian craton, is part of a geological context with considerable metallogenic potential for base metals, although significant deposits are not known yet. The presentpaper aimed to process aeromagnetometry and aerogammaspectrometry data for integration with geochemical and geological mapping campaigns in order to build aprospectivity model for nickel in the NBMB region of in a 1:500,000 scale. Using knowledge-driven approach modelling, fuzzy logic was chosen to combine geophysics,geochemistry and geological mapping data. As result, it was possible to build a prospectivity model for nickel, consistent with the distribution of nickel occurrencesregistered by the Geological Survey of Brazil (Servic¸o Geol´ogico do Brasil – CPRM), and witch may guide detailed prospecting campaigns in the region.Keywords: airborne geophysics, fuzzy logic, prospective modelling, metasedimentary belt, Nova Brasilândia.RESUMO.

Subway tunnel construction plays a significant role in the development of urban underground space. Advance surface grouting treatment of adverse subsurface geological bodies is an effective measure to avoid the accidents during subway construction. This paper describes the successful application of geological prospecting and grouting assessment at the tunnel site of Qingdao subway line No. 1. The study area is located in a coastal bedrock fissure water distribution area. It was decided to conduct surface grouting to reduce the high risk of water inrush. Integrated investigation consisting of electrical resistivity tomography (ERT), seismic ahead prospecting, surface vertical drilling and cross-hole ERT was conducted to ascertain the geological conditions and guide the grouting scheme design. Surface ERT and seismic ahead prospecting were adopted to provide a rough survey of water bearing conditions and fractured zones. Then, detailed imaging was conducted using cross-hole ERT inversion with the inequality constraint based on the information obtained using surface vertical drilling. The shape and location of three water bearing structures were identified. Based on the integrated investigation results, an appropriate grouting scheme was designed. After the application of grouting, cross-hole ERT was carried out again to assess the effect of grouting by comparing the vibration of twice inversion results of cross-hole ERT and resistivity tests of the grout sample. Such information serves as a basis for guiding geotechnical excavations in complex urban environments and avoids the risk of construction accidents.

Sugar cane bagasse flour (Saccharum officinarum L.) is a promising product and has great market potential with application in human food. With the help of technological and scientific prospecting, it is possible to guide and cover the view on research about the use of this material in the area of food science. With that, the objective was to investigate the existence of the development of sugarcane bagasse flour in technological and scientific databases. The patent bases analyzed were the National Institute of Industrial Property (NIIP), the World Intellectual Property Organization (WIPO), the United States Patent and Trademark Office (USPTO) and the Espacenet Patent Search database. The scientific platforms analyzed were Scientific Electronic Library Online (SciELO), Web of Science, Pubmed and Portal Periódicos Capes (Brazil). Brazil has made progress in intellectual production on patent bases, however, no technological and / or scientific record has been identified regarding the use of flour for human consumption in the analyzed period. From this, it is necessary, then, to carry out research on the food potential of this flour, mainly in Brazil, since the country is considered the largest producer of sugarcane, having a vast material to be explored, developing functionality in the development of new products and increasing intellectual property in the area.

Dachang ore field is located in the central of Au, Sb, Hg metallogenic belt in the north Bayankela mountain, with the Maduo - Gande deep major fault as its regional guide mineral structure. The gold deposits have grew up in the fracture - fissure system of large share zone in BaYanKaLa mountain group of Triassic strata, and Magmatic activities in Yanshan Period provides favorable conditions for the activation, migration, enrichment and mineralization of gold element. Geophysical - geochemical anomaly and remote sensing of this area have shown that they are related with the mineralization, that means abnormal area with bigger Intensity is often located in the cross area of tectonic alteration and mineralization. Triassic strata, the north - west fault and its secondary structure - rock system and geophysical - geochemical anomaly are the obvious symbols of gold prospecting in the area. Through the metallogenic regularity, obvious symbols and distincting some geophysical - geochemical anomalies, more large and medium-sized gold deposits have been found. We should along the Maduo - Gande fault zone, extending for east - west trend and the depth, and larger scale gold deposits is expected to be found.

Percussion drilling has been widely used in oil and gas industry, yet it still has some shortcomings, such as severe damages to drilling tools, low energy transferring efficiency and low rock-fragmenting efficiency. Thus it is necessary to reveal the mechanism of interactions between the hammer bit and rock in geophysical prospecting percussion drilling. Taking account of the coupling effect of the Weight on Bit (WOB), impact force and rotary torque, this paper constructed a Finite Element Method (FEM) model using the finite element analysis software (ANSYS/LS-DYNA) and conducted a computer simulation of bit-rock interaction under rotating and simple impact effect, which showed the rock-fragmenting process of hammer bit and the curves of volume-time and depth-time of craters as well as the effective stress-time curves of the centre tooth, second-row tooth and peripheral tooth. The results showed that: the percussion drilling process under rotating impact effect is characterized as four fundamental processes; the crater depth mainly depends on impact force rather than rotary torque; the crater created under rotating impact effect is twice the volume of that under impact effect; the effective stress of each tooth changes severely: the stress of second-row tooth is the largest, centre tooth the second, and peripheral tooth the smallest. This study provided a guide for the structural optimization of hammer bit and general applications of percussion drilling.

L’existence de fluides géologiques riches en hydrogène (H2) doit nécessairement faire l’objet de travaux d’exploration afin de statuer sur le potentiel énergétique de cette éventuelle ressource décarbonée. Depuis plus d’un siècle de nombreuses exhalations naturelles d’H2 ont été mis en évidence. Or à ce jour il n’existe aucun guide d’exploration basé sur une méthodologie et sur des indicateurs robustes. La détection d’occurrence gazeuse en surface correspond bien évidemment à l’approche la plus efficace et la plus rapide à mettre en œuvre pour identifier des flux. Il n’en reste pas moins qu’un flux ne constitue pas une ressource pour autant, puisqu’à ce jour, l’homme n’exploite que les stocks de ressources énergétiques fossiles. Il sera donc important de développer un guide d’exploration non pas orienté uniquement sur une problématique de surface, mais aussi sur des considérations géologiques profondes intégrant le système hydrogène dans son entier de la source au piège ou à la fuite dans l’atmosphère.Au cours de ce travail de thèse nous proposons d’utiliser le cadre géologique du piémont nord Pyrénéen pour élaborer un guide d’exploration. La compilation des données bibliographiques a révélé un contexte prometteur pour un système H2 du fait d’un lien entre sources profondes, chemins de migration crustale, dynamique de circulation de fluides, et pièges sédimentaires. En effet le nord-ouest des Pyrénées et plus particulièrement le Bassin Mauléon est caractérisé par la présence i) d’un corps mantellique (<10 km) où les conditions pression-température sont favorables à la serpentinisation ; ii) d’accidents structuraux majeurs tels que le Chevauchement Frontal Nord Pyrénéens (CFNP) constituant des drains collecteurs de grande ampleur, iii) des gradients hydrauliques, conjugués à des gradients de température et de pressions qui permettent la mise en mouvement des fluides ; iv) des formations sédimentaires imperméables ou de couvertures comme les évaporites ou les argiles consitutant des pièges pour accumuler l’H2.Suite à cette étude préalable, nous avons mis en place une campagne d’analyses des gaz du sol (H2, CO2, 222Rn, O2, CH4) à l’échelle régionales. Cette campagne d’analyse réalisée sur plus de 7500 km2 a très vite permis de mettre en évidence une zone à très fortes anomalies en H2, CO2, et 222Rn sur le pourtour du Bassin de Mauléon. Cette découverte nous a permis de resserrer rapidement le maillage de prospection sur la partie nord du bassin de Mauléon. Une campagne d’analyses géochimiques et géophysiques a été réalisée à Sauveterre-de-Béarn afin de déterminer l’origine et le parcours des gaz à l’origine de cette anomalie. Sur la base de l'analyse des gaz du sol et des levés électromagnétiques, nous avons confirmé l'existence d'une faille drainant les fluides profonds. De plus, l’étude des données historiques des forages entrepris dans la région il y a plus de 50 ans, conjugué à une mise en perspective des dernières connaissances géologiques et géophysiques de la région, nous a permis de mettre en évidence des zones où l’H2 pourrait s’accumuler.Enfin une partie expérimentale de broyage de quartz et de roches de la région a été menée afin d’explorer de nouveaux mécanismes de production d’H2 le long des failles. Nous avons mis en évidence une très forte influence du rapport eau/roche (W/R) et du pH sur la production d’H2. Ces découvertes apportent un éclairage nouveau sur les mécanismes mécano-radicalaires de production d’H2 où la spéciation des sites des surface des minéraux sont des paramètres clés contrôlant la production d’H2. Nous révélons pour la première fois que le broyage du quartz en présence de solutions carbonatés induit la formation d’espèces carboxylates (formate, acétate, oxalate). En plus de produire de l’H2, les mécanismes mécano-radicalaires permettent donc de produire des espèces réduites du carbones pouvant constituer une source d’énergie pour les écosystèmes microbiens lithotrophe de subsurface
The existence of geological fluids rich in hydrogen (H2) rise the question about the energy potential of this carbon-free resource. For more than a century and throughout the world, numerous natural H2 seepages have been discovered. However, to date there is no exploration approach based on robust methodologies and pathfinders. The detection of H2 seepages at the surface is known to be the most ecient and straight forward approach to identify H2 flows. However, a gas flow does not necessarily constitute a resource, since to date, mankind only exploit reservoirs of fossil energy resources. Therefore, it is important to develop an exploration guide that is not only focusing on surface gas monitoring, but also considering a deep geological approach integrating the entire hydrogen system from source to trap or leakage into the atmosphere. Here, we propose to use the geological framework of the North Pyrenean foothills as a case study to develop this exploration guide. A literature review of the area revealed a promising geological setting for a H2 system due to a strong link between putative deep H2 sources, crustal-scale migration pathways, fluid circulation dynamics, and sedimentary traps. Indeed, the northwestern Pyrenees and particularly the Maul´eon Basin is characterised by the presence of i) an ultramafic mantle body located less than 10 km depth and under pressure-temperature conditions favourable to serpentinisation ; ii) major faults such as the North Pyrenean Frontal Thrust (NPFT) constituting large-scale flow convergence and drainage, iii) hydraulic gradients due to the presence of strong reliefs, combined with temperature and pressure gradients that trigger fluids ; iv) impermeable sedimentary formations or caprocks such as evaporites or claystones overlying porous reservoir rocks that can constitute traps for accumulating H2.Following this preliminary geological survey, we set up a soil gas exploration campaign (H2, CO2, 222Rn, O2, CH4) at the regional scale. These field measurments, carried out over more than 7,500 km2, revealed several hotspots with very high H2, CO2 and 222Rn concentrations anomalies around the Maul´eon Basin. This discovery allowed us to refine the mesh of the prospecting grid to the northern part of the Maul´eon Basin around the locality of Sauveterre-de-Béarn. Geochemical and geophysical measurements were carried out at Sauveterre-de-B´earn to determine the source and migration path of the gases at the origin of this anomaly. Based on soil gas analysis and electromagnetic surveys, we confirmed the existence of a fault draining deep fluids. In addition, the study of historical data from drilling carried out in the region more than fifty years ago, combined with the latest geological and geophysical knowledge of the region, enabled us to highlight zones where H2 could accumulate.Finally, an experimental part of comminution of quartz and rocks from the region was carried out in order to explore the reaction mechanisms of H2 production in active fault zones. We reveal the very strong influence of the water/rock ratio (W/R) and pH on H2 production. These findings shed new light on the mechano-radical mechanisms of H2 production where the efficiency of grinding as well as the speciation of mineral surface sites are key parameters controlling H2 production. We reveal for the first time that grinding of quartz in the presence of carbonate solutions induces the formation of carboxylate species (formate, acetate, oxalate). In addition to producing H2, the mechano-radical mechanisms thus allow the production of reduced carbon species that can constitute an energy source for subsurface lithotrophic microbial ecosystems

The United States Naval Facilities Engineering Command awarded over 1-billion dollars in construction contracts in 1990 and is expected to increase that figure in 1991. These contracts will be awarded all over the world. They will range in size from five thousand dollar playgrounds to hundred million dollar buildings. The objective of this paper is to develop a guide that will allow contractors to make a smooth transition from contracting with other sources into contracting with the United States Navy. It will cover various areas that often lead to difficulties for contractors unfamiliar with Navy construction contracting. Also the guide will provide an overview of the entire contracting experience from reading the advertisement for the job, to the warranty period after construction. It should be understood that the information presented in this guide applies to the most common type of construction contract used by the Navy - fixed price/lump sum.

Lévolution des modes de vie conduit à une évolution des besoins et des souhaits des personnes, en quête «d'expérience », de « bien-être » et de « plaisir » à travers les produits qu'elles utilisent. Les entreprises doiventaujourd'hui satisfaire et séduire ces personnes de plus en plus exigeantes, en étant source d'innovation et denouveauté. Ainsi, elles s'intéressent de plus en plus dans leur démarche de conception de produits à une meilleureprise en compte du facteur humain. Faire vivre aux personnes des expériences positives et de qualité, demandeune démarche spécifique qui les placent au centre des préoccupations des acteurs-métier de la conception deproduits. Dans ce contexte, le processus de conception requiert l'intervention de différentes disciplines sensiblesjustement au facteur humain. Ainsi dans le cadre de nos travaux de recherche, nous nous sommes intéressés aurapprochement de l'ergonomie et du design, deux disciplines sensibles aux personnes qui évoluent vers denouvelles pratiques : le design pour « des besoins » et l'ergonomie prospective. Nous axons nos travaux derecherche sur les pratiques de ces deux disciplines qui convergent vers une vision commune, prospective et «humaniste » de la conception de produits, pour une meilleure prise en compte des personnes. Le principal enjeuscientifique de notre travail est de mieux cerner les pratiques actuelles, de l'ergonomie et du design dans uncontexte de conception de produits. Ceci, pour proposer à ces acteurs-métier une démarche (IDLifeS) et des outils(Guides de Connaissances), interdisciplinaires, qui correspondent à l'évolution de leurs pratiques respectives et quileur permettent de co-concevoir des produits et des situations de vie qui correspondent aux besoins, aux souhaits etaux caractéristiques des personnes
Lifestyles change led to the development of the needs and wishes of people who are looking for "experience", "wellbeing"and "pleasure" through the products they use. Companies must now satisfy and seduce these people whoare increasingly exigent, by being a source of innovation and new ideas. Thus, companies are more and moreinterested in their product design process, in order to better take into account, the human factor. It requires aspecific approach to make people have positive and quality experiences. In this approach, people are at the heart ofthe concerns of the product design actors. In this context, the design process requires the intervention of differentdisciplines rightly sensitive to human factor. In our research, we focused on ergonomics and design, two disciplinessensitive to people who are moving towards new practices: design for "needs" and the prospective ergonomics. Ourresearch is focus on the practices of these two disciplines that converge on a common vision, which is a prospectiveand "humanist" one, of the product design for a better integration of people. The main scientific challenge of ourwork is to better understand ergonomics and design current practices in a product design context. This, to suggestto these actors an approach (IDLifeS) and tools (Knowledge Guides), interdisciplinary, which correspond to thedevelopment of their practices and offer them to co-design products and life situations which correspond to theneeds, wishes and characteristics of people

A região de Itutinga foi alvo de estudos prospectivos por parte da empresa BP mineração na década de 80, onde foram encontradas mineralizações em lentes de sulfetos metálicos (Zn-Cu-Ag-Fe) associados a rochas komatiíticas peridotíticas e basaltos toleíticos (anfibolitos) do greenstone belts, nas proximidades da fazenda São Jerônimo, enquadrando-se em um depósito do tipo VMS. A partir destas informações encontradas na literatura propôs-se estudar a estaurolita, a magnetita e a ilmenita para, a partir da determinação do seu conteúdo em zinco, indicar a aplicabilidade destes três minerais como traçadores desses tipos de depósitos. Para isso foram coletadas amostras de sedimentos de corrente e concentrados de batéia na região próxima à ocorrência, no entorno da cidade de Itutinga, e também em uma região próxima a cidade de Itumirim, já que existem semelhanças litológicas entre as duas áreas. Os sedimentos de corrente, as frações magnéticas e as frações de 0,3A (separador eletromagnético Frantz) foram enviados para análises químicas por absorção atômica e ICP-OES. Os concentrados de batéia foram descritos, separando-se cristais de estaurolita de cada amostra coletada, e analisando-os em MEV-EDS para determinação da química mineral. Os resultados dos sedimentos de corrente apontaram que os pontos da fazenda São Jerônimo (ME-03, Itutinga 51,7 ppm de Zn) e o ponto do Ribeirão Santa Cruz, (ME-06, Itumirim 36,1 ppm de Zn) foram os que apresentaram melhores resultados, indicando anomalias em zinco nas duas áreas estudadas . As estaurolitas, retiradas dos concentrados de batéia de cada ponto estudado, foram divididas em três conjuntos, de acordo com os teores de ZnO encontrados: 1 - entre 2,96% e 3,25% de ZnO em peso; 2 - entre 2,03% e 2,76% de ZnO em peso; 3 - < 1,67% de ZnO em peso, sendo comparável com outras estaurolitas encontradas em diversos depósitos de Zn do mundo, como Dry River, Austrália e Palmeirópolis Goiás. Assim, as estaurolitas apresentam bons resultados como minerais indicadores na área estudada. Em relação as magnetitas e ilmenitas estudadas, o número de amostras coletadas no presente estudo foram muito pequenas para se ter informações conclusivas sobre o papel destes minerais como traçadores. Por outro lado, os resultados das análises químicas nos concentrados de ilmenita (até 856 ppm de Zn) e nos concentrados de magnetita (até 216 ppm de Zn), indicam a disponibilidade deste metal nas áreas estudadas. Assim, é possível se detectar a presença do zinco por dois meios: através de sedimentos de corrente, através de halos de dispersão química do elemento zinco, e através dos minerais resistatos (estaurolita zincífera, magnetita e ilmenita), a partir de uma dispersão clástica do grão.
The Itutinga region was studied for BP mineration in 80s , where they found sulphide mineralization in lenses (Zn-Cu-Ag-Fe) associated with komatiitic peridotite rocks and tholeitic basalts (amphibolites) of greenstone belts, near of Fazenda São Jerônimo. With this information in the literature the propose is study the staurolite, magnetite and ilmenite for indicating the applicability of these three minerals as tracers of these types of mineralization. For this, samples of stream sediment and panning concentrates in the region near the city of Itutinga, and also in a region near the city of Itumirim. The stream current, magnetic fractions and ilmenite fractions were sent to chemistry analyses (Atomic absorption and ICP-OES), and the panning concentrates were analyzed for the separating of staurolite crystals, and sent to SEM-EDS. The stream sediments results showed that the point of Fazenda São Jerônimo (ME-03, Itutinga 51,7 ppm of Zn) and the point of Ribeirão Santa Cruz (ME-06, Itumirim 36,1 ppm of Zn) were presented the best result. The staurolite of panning concentrates were divided into three groups according to levels of ZnO matched: 1 - between 2.96% and 3.25% by weight of ZnO, 2 - from 2, 03% and 2.76% by weight of ZnO, 3 - <1.67% ZnO by weight, comparable with other staurolite found in many zinc deposits in the world, such as Dry River, Australia and Palmeirópolis Goiás. Thus, the staurolite show good results as indicator minerals in the area. With respect to magnetite and ilmenite concentrates, the number of samples collected in both areas was too small to have conclusive information. On the other hand, the results of the chemical ilmenite (up to 856 ppm Zn) and magnetite (up to 216 ppm Zn), indicate the availability of this metal in the areas studied. Thus, it is possible to detect the presence of zinc by two means: through stream sediments through chemical dispersion halos of zinc, minerals and through resistive minerals (zincian staurolite, magnetite and ilmenite), from a crystal clastic dispersion.

Aims: The aim of this study was to compare two different methods of root surface debridement for the treatment of moderate to advanced chronic periodontitis; fluorescence-guided laser debridement using an Er:YAG laser (ERL) or mechanical scaling and root-planing (SRP/UL) using an ultrasonic scaler and hand instruments. The effectiveness of each treatment method was assessed by patient-centred outcomes such as clinical periodontal measurements and patients� overall experience. Methods: This study was a phase IV randomised controlled clinical trial, with all examinations and treatments carried out between 1st February 2007 and 7th March 2008. Using a split-mouth design, each patient received both test and control treatments. The control quadrants received scaling and root planing using a Piezon� (EMS, Nyon, Switzerland) ultrasonic scaler and Gracey curettes, while the test quadrants received fluorescence-guided Er:YAG laser root debridement (Keylaser 3, Kavo, Biberach, Germany; panel settings 160mJ/pulse, 10Hz, water spray, 655nm fluorescence calculus-detection system). Full mouth clinical measurements [plaque index (PlI), probing depth (PD), gingival recession (GR), bleeding on probing (BOP), and clinical attachment level (CAL)] were recorded at baseline, and 6 and 12 weeks post-therapy. A patient questionnaire was used to evaluate patient perception in terms of pain, discomfort and satisfaction during treatment, and 24 hours and one week post-treatment. A wash-out period of 6 weeks enabled each patient to evaluate their experience of each treatment on its own merit. Results: Twenty-eight patients received both treatments and completed the patient perception questionnaire. No significant difference was found between ERL and SRP/UL in terms of pain and discomfort during treatment, and 24 hours and one week post-treatment. In terms of patient satisfaction, none of the patients rated ERL more favourably than SRP/UL immediately following treatment, however no significant difference was found 24 hours later and one week post-therapy. Complete clinical data was collected for 22 patients, four of whom increased their tobacco consumption to [greater than or equal to] 10 cigarettes/day. Therefore, the analysis of clinical data was carried out twice with respect to patients� smoking status. In patients who smoked [less than or equal to] 9 cigarettes/day (n = 18 patients), ERL provided less PD reduction at 6 and 12 weeks (p < 0.001, 6 weeks; p < 0.05, 12 weeks) than SRP/UL. Even though SRP/UL quadrants had a greater proportion of sites with BOP (% BOP) at baseline, at 6 weeks they showed a significantly greater reduction in %BOP (p = 0.0123) than ERL quadrants, however there was with no significant difference in bleeding scores (p = 0.202) at 12 weeks post-therapy. When patients who smoked [greater than or equal to] 10 cigarettes/day were included in the analyses (n = 22 patients), ERL resulted in less BOP reduction and PD reduction at 6 and 12 weeks following treatment (BOP reduction: 6 weeks p < 0.05, 12 weeks p < 0.001; PD reduction: 6 weeks p < 0.01, 12 weeks p < 0.05). Although statistically significant, the differences between the treatment groups were very small and were not clinically significant. Conclusion: The use of ERL for root surface debridement offers no significant advantages over mechanical therapy in the treatment of moderate to advanced chronic periodontitis, in terms of clinical outcomes and patient perception of pain, discomfort or satisfaction related to the procedure.

Avec l’avènement du traitement distribué et l’utilisation accrue des services web inter et intra organisationnels alimentée par la disponibilité des connexions réseaux à faibles coûts, les données multisources partagées ont de plus en plus envahi les systèmes d’informations. Ceci a induit, dans un premier temps, le changement de leurs architectures du centralisé au distribué en passant par le coopératif et le fédéré ; et dans un deuxième temps, une panoplie de problèmes d’exploitation allant du traitement des incohérences des données doubles à la synchronisation des données distribuées. C’est le cas des bases de prospection marketing où les données sont enrichies par des fichiers provenant de différents fournisseurs.Nous nous intéressons au cadre particulier de construction de fichiers de prospection pour la réalisation de campagnes marketing B-to-B, tâche traitée manuellement par les experts métier. Nous visons alors à modéliser le raisonnement de brokers humains, afin d’optimiser et d’automatiser la sélection du « plan fichier » à partir d’un ensemble de données d’enrichissement multisources. L’optimisation en question s’exprimera en termes de gain (coût, qualité) des données sélectionnées, le coût se limitant à l’unique considération du prix d’utilisation de ces données.Ce mémoire présente une triple contribution quant à la gestion des bases de données multisources. La première contribution concerne l’évaluation rigoureuse de la qualité des données multisources. La deuxième contribution porte sur la modélisation et l’agrégation préférentielle des critères d’évaluation qualité par l’intégrale de Choquet. La troisième contribution concerne BrokerACO, un prototype d’automatisation et d’optimisation du brokering multisources basé sur l’algorithme heuristique d’optimisation par les colonies de fourmis (ACO) et dont la Pareto-optimalité de la solution est assurée par l’utilisation de la fonction d’agrégation des préférences des utilisateurs définie dans la deuxième contribution. L’efficacité du prototype est montrée par l’analyse de campagnes marketing tests effectuées sur des données réelles de prospection
In Business-to-Business (B-to-B) marketing campaigns, manufacturing “the highest volume of sales at the lowest cost” and achieving the best return on investment (ROI) score is a significant challenge. ROI performance depends on a set of subjective and objective factors such as dialogue strategy, invested budget, marketing technology and organisation, and above all data and, particularly, data quality. However, data issues in marketing databases are overwhelming, leading to insufficient target knowledge that handicaps B-to-B salespersons when interacting with prospects. B-to-B prospection data is indeed mainly structured through a set of independent, heterogeneous, separate and sometimes overlapping files that form a messy multisource prospect selection environment. Data quality thus appears as a crucial issue when dealing with prospection databases. Moreover, beyond data quality, the ROI metric mainly depends on campaigns costs. Given the vagueness of (direct and indirect) cost definition, we limit our focus to price considerations.Price and quality thus define the fundamental constraints data marketers consider when designing a marketing campaign file, as they typically look for the "best-qualified selection at the lowest price". However, this goal is not always reachable and compromises often have to be defined. Compromise must first be modelled and formalized, and then deployed for multisource selection issues. In this thesis, we propose a preference-driven selection approach for multisource environments that aims at: 1) modelling and quantifying decision makers’ preferences, and 2) defining and optimizing a selection routine based on these preferences. Concretely, we first deal with the data marketer’s quality preference modelling by appraising multisource data using robust evaluation criteria (quality dimensions) that are rigorously summarized into a global quality score. Based on this global quality score and data price, we exploit in a second step a preference-based selection algorithm to return "the best qualified records bearing the lowest possible price". An optimisation algorithm, BrokerACO, is finally run to generate the best selection result

AbstractTraditionally, volleyball coaches’ education has been conducted physically in the gym and classroom, but due to Covid-19 and the actions needed to contain the pandemic, that was no longer possible in the spring of 2020. Instead of canceling the already planned course we decided to move the course online. The development process was guided by the question if we can teach volleyball-specific skills online. As a result, we designed a fully online blended learning course with a problem-centered approach and authentic video-based tasks. A total of 23 prospective coaches took part in the course. Skills acquisition was measured using a pretest-posttest design revealing a large effect of our design on skills acquisition. Additionally, we surveyed participants attitudes towards the learning design. The results show that prospective coaches were satisfied with the design and perceived the online learning course as useful for volleyball coaches’ education. Based on the results, we can recommend the combination of videos and interactive content to provide authentic problem-centered tasks to facilitate skills online in volleyball coaches’ education.

Abstract The Middle East contains some of the most fascinating and prolific oil provinces in the world. The combination of excellent source rocks of different geologic ages, the presence of outstanding reservoirs and ubiquitous seals, optimal thermal history, and structural evolution provides an ideal recipe to produce the largest oilfields in the world. The UAE is currently estimated to hold 6% of global oil reserves, 96% of which are within Abu Dhabi. However, exploration for additional recoverable reserves is becoming more challenging. Finding hydrocarbons for the future is dependent upon a detailed understanding of the petroleum systems and subtle play types. For southeastern Abu Dhabi, several petroleum systems have been proposed to explain the oil and gas accumulations in Lower Cretaceous reservoirs. This study presents the practical application of a geochemical inversion workflow to a set of oil samples from Lower Cretaceous reservoirs collected in two exploration wells recently drilled in southeastern Abu Dhabi. The geochemical inversion workflow is based on stable isotope, biomarker, and oil composition data. Preliminary results and comparisons with previously identified oil families in the UAE suggest that the oils were generated from a carbonate-rich source rock deposited during Jurassic time. Compositional data and detailed stratigraphic and structural analyses support the possibility of multiple episodes of lateral and vertical migrations. The implications and risk associated with the timing of oil generation and trap formation are presented here to define a path forward and guide the prospecting efforts within this exciting region.

In this paper we describe a model of pedagogical content knowledge with a formative cycle directed to simultaneously increase the teachers’ statistical and pedagogical knowledge. In this cycle, teachers are first given a statistical project to work with and then carry out a didactical analysis of the project. An analysis guide, based on the notion of didactical suitability, helps increase the teachers’ competence related to the different components of pedagogical content knowledge and their ability to carry out didactical analyses. At the same time it provides the teacher educator with information regarding the future teachers’ previous knowledge and learning. Results of experimenting with this formative cycle for a particular project in a group of 55 prospective teachers indicated a need for better statistics preparation of these teachers and illustrated the usefulness of the formative cycle and analysis guide proposed.

Background: With advent of surgical advancements like HIPEC several unstudied pathophysiological aspects need to be evaluated. We studied the trends in coagulation profile in patients undergoing CRS with HIPEC in the peri-operative period, utilizing Thromboelastography (TEG) in comparison with standard coagulation tests. The utility of TEG as a guide for transfusion of blood products was also evaluated. Materials and Methods: It was a Prospective observational Cohort study which included 30 consecutive patients undergoing CRS with HIPEC at RGCI in 2015. Methodology: Preoperatively standard coagulation tests were done as a baseline. Intra-operative arterial blood samples were collected for ABG, PT, APTT, and TEG at following time points: before starting of HIPEC, after completion of HIPEC and on 1 and 2 postoperative days. Statistical analysis was done using Chi-square test and unpaired t-test for categorical and continuous variables. Pearson’s correlation coefficient was calculated for analysing the correlation between the variables. P < 0.05 was considered statistically significant. Results: A strong correlation was observed between PT & R values of TEG. Similar correlation was also observed between the α angle, MA of TEG and platelet count throughout the peri-operative period. Immediately post HIPEC, we observe value of APPT decreases while the other parameters of coagulation profile showed a rising trend. R value showed rising trend after CRS, a dip after HIPEC followed by a rising trend on first post operative day which normalizes only after second post operative day. It gives a mixed picture of both hypo and hyper coagulable state. α angle, MA rise immediately after HIPEC and continue to rise till the second postoperative day. There was no requirement of transfusion of blood and blood products as guided by the TEG findings and no clinical evidence of any bleeding or thromboembolic episode occurred. Conclusion: To conclude, our study demonstrated TEG to be a useful and comprehensive tool to assess coagulopathy and accordingly guide blood product transfusion in patients undergoing CRS with HIPEC.

Intro: Undifferentiated dyspnea can be a complicated presentation muddled by patient comorbidities and similar symptomology shared among etiologies. Some studies have shown increased mortality and length of stay in the hospital when incorrectly initially diagnosed in the ED. US has been shown more effective at differentiating these causes and improves diagnostic accuracy. This study will implement US exam upon initial exam of patient and chart time to diagnosis/treatment, length of stay in ED, length of stay in hospital admissions versus discharge rates, and 30 day mortality. ADHF and COPD/asthma patient differentiation will be the focus. Methods: Prospective cohort study of more than 18 years that present with the primary complaint of dyspnea with more than one complicating comorbid condition. Initial exam by physician will be accompanied by cardiothoracic US previously verified. Results: Study powered by previous year average of time to diagnosis of institution. Patient characteristics, distribution by diagnostic category, and characteristics found on US in correlation with diagnosis will be included for multivariate analysis. Conclusions: We expect to see a singificant difference in our time to diagnosis/treatment and mortality rate.
