Abstract:
In the context of thermal conduction taken as a prototype of numerous transport phenomena, a general method is elaborated to study Eshelby's problem of inclusions inside a bounded homogeneous anisotropic medium. This method consists in: (i) recasting by a linear transformation the initial problem into Eshelby's problem of the transformed inclusion inside the transformed finite isotropic medium and (ii) decomposing Eshelby's problem of a thermal inclusion embedded in a finite isotropic medium into the sub-problem of the same inclusion inside the associated infinite medium and the sub-problem of the finite ambient isotropic medium including no inclusion but undergoing appropriate compensating boundary conditions. The general method is applied in the two-dimensional situation and the corresponding temperature field and Eshelby's conduction tensor are explicitly expressed in terms of some curvilinear complex integrals for the Dirichlet and Neumann boundary conditions. Thus, the difficulties owing to the unavailability or non-existence of Green's function are overcome. The general results in the two-dimensional case are finally specified and illustrated by considering a finite circular medium with circular or polygonal inclusions.

Abstract:
The thermal transportation caused by absorbing inclusions in optical films under the radiation of laser pulse is unsteady heat conduction. The temperature distribution in films is ununiform and time-dependent. Considering the small size of inclusions, the absorbing inclusions were treaded as dot-heat sources. Based on this assumption, the unsteady heat conduction model was brought out and the temperature distribution in films was figured out and discussed, the mechanism that the catastrophic damage may avoid with micro-damage or micro-deformation in films through the release of stress concentration is presented. By comparing the thermal effects caused respectively by single inclusion and assembling ones, the effect of inclusion size on thermal damage in films was discussed.

Abstract:
Composites with hybrid inclusions have shown remarkable thermal conductivity enhancement over composites with a single type of inclusion. However, to achieve maximum thermal conductivity enhancement, the optimum ratio of inclusions in the hybrid mix needs to be determined. In this communication, an effective medium theory based model for the estimation of effective thermal conductivity of composites with hybrid inclusions is presented. The proposed model accurately captures the synergic effect of hybrid inclusions within the composite and can be used to optimise the filler ratio in the hybrid mix. The model has been validated against several published experimental results and is found to be in good agreement with them. Parametric studies have also been carried out to study the effect of material and model parameters on the optimum ratio of hybrid inclusions.

Abstract:
It is well established that the fluorescence colours of crude oils shift towards the blue end of the spectrum with increased API gravity and implied thermal maturity. Oil inclusions also fluoresce, and it would be useful to correlate these fluorescence colours likewise to thermal maturity, because oil inclusions often contain the only direct evidence of residual oils once present in a reservoir. In order to validate this concept, the geochemical and petrographic properties of fluid inclusion oils in 36 sandstone samples from Australasian oil fields have been compared. A maturity assessment was made for each fluid inclusion oil using 25 molecular maturity ratios. Each fluid inclusion oil was placed in one of four maturity brackets, approximately equivalent to early, mid, peak and post oil generation windows.Samples containing mainly blue-fluorescing oil inclusions have thermal maturities throughout the oil window, including relatively low maturities (Rc

Abstract:
The thermal effect arisen from absorbing inclusions is the main factor which causes the damage of optical materials or component irradiated by the longer pulse duration laser. The unsteady heat conduction depends markedly on both the thermal properties of inclusions and the parameters of laser. Based on the differential equation of heat conduction, the temperature distribution caused by single absorbing inclusion is solved by use of finite difference method. The effect of the laser intensity and the pulse duration on temperature field is analyzed in detail. The result demonstrates that the smaller size inclusion and the smaller pulse duration cause relative safe thermal effect, consequently, the less probability to be damaged by thermal effect.

Full text
Abstract:
Thermal motion of nanoscale liquid Pb inclusions attached to fixed dislocations in thin Al foils is investigated using in-situ TEM. In contrast with 3D random motion of free inclusions, the attached inclusions demonstrate oscillations in the close proximity of the dislocations. This is due to the elasticity of the dislocations. It is found that inclusions captured by one dislocation repulse at small separations, and attract at large ones and this is also caused by the dislocation elasticity. Such behaviour of trapped inclusions can be considered as a motion in a potential well or in coupled potential wells in the case of motion of several trapped inclusions on one dislocation. The potential of interaction of an inclusion with a dislocation and the potential of mutual interaction between inclusions are determined.

Abstract:
The Linxing area is located in the north of the eastern margin of the Ordos Basin, which has great resource potential for tight gas. In this paper, fluid inclusion analysis and basin modeling are the main means to clarify the gas accumulation mechanism of the Upper Paleozoic in the Linxing area. Petrographic analysis shows that fluid inclusions can be classified into 5 types: aqueous inclusions, hydrocarbon-bearing aqueous inclusions, hydrocarbon inclusions, crystal-bearing aqueous inclusions, and aqueous-carbonic inclusions. According to the statistical analysis of homogenization temperature and salinity of fluid inclusions, combined with the burial-thermal evolution, the study area was divided into 3 areas: the inner-magma baking area, the middle-anomal thermal area, and the outer-normal thermal area. The gas accumulation characteristics are differences among the 3 areas, the closer to Zijinshan magmatic pluton, the earlier gas accumulation period; and the vertical gas accumulation in the inner-magma baking area and the middle-anomal thermal area was not a slow and gradual process from bottom to top. The period from the Middle Jurassic to the Early Cretaceous is the key period for rapid pressure accumulation in the Upper Paleozoic reservoirs, which is consistent with the period of natural gas accumulation. The area near the Zijinshan magmatic pluton was the high fluid potential area during the gas accumulation period, which indicates that natural gas and other fluids migrated from Zijinshan magmatic pluton to the surrounding area. It is concluded that in the Linxing area, the Zijinshan magmatic pluton had a significant impact on natural gas accumulation, and the natural gas accumulation model under the control of magmatic thermal-tectonic effect was proposed.

Abstract:
The problem of determining nonlinear neutral inclusions in (electrical or thermal) conductivity is considered. Neutral inclusions, inserted in a matrix containing a uniform applied electric field, do not disturb the field outside the inclusions. The well-known Hashin-coated sphere construction is an example of a neutral inclusion. In this paper, we consider the problem of constructing neutral inclusions from nonlinear materials. In particular, we discuss assemblages of coated ellipsoids. The proposed construction is neutral for a given applied field.

Abstract:
Many geologic processes occur in association with hydrothermal fluids and some of these fluids are eventually trapped as fluid inclusions in minerals formed during the process. Fluid inclusions provide valuable information on the pressure, temperature and fluid composition (PTX) of the environment of formation, hence understanding PTX properties of the fluid inclusions is required. The most important step of a fluid inclusion study is the identification of Fluid Inclusion Assemblages (FIA) that represent the finest (shortest time duration) geologic event that can be constrained using fluid inclusions. Homogenization temperature data obtained from fluid inclusions is often used to reconstruct temperature history of a geologic event. The precision with which fluid inclusions constrain the temperatures of geologic events depends on the precision with which the temperature of a fluid inclusion assemblage can be determined. Synthetic fluid inclusions trapped in the one-fluid-phase field are formed at a known and relatively constant temperature. However, microthermometry of synthetic fluid inclusions often reveals Th variations of about ± 1- 4 degrees Centigrade, or one order of magnitude larger than the precision of the measurement for an individual inclusion. The same range in Th was observed in well-constrained natural FIAs where the inclusions are assumed to have been trapped at the same time. The observed small variations are the result of the effect of the fluid inclusion size on the bubble collapsing temperature. As inclusions are heated the vapor bubble is getting smaller until the pressure difference between the pressure of the vapor and the confining pressure reaches a critical value and the bubble collapses. It was observed that smaller inclusions reach critical bubble radius and critical pressure differences at lower temperatures than larger inclusions within the same FIA. Homogenization temperature (Th) variations depend on many factors that vary within different geological environments. In order to determine minimum and acceptable Th ranges fro FIAs formed in different environments we investigated several geologic environments including sedimentary, metamorphic, and magmatic hydrothermal environments. The observed minimum Th ranges range from 1-4 degrees Centigrade and acceptable Th range from 5-25 degrees Centigrade. The variations are mostly caused by the fluid inclusion size, natural temperature and pressure fluctuations during the formation of an FIA and reequilibration after trapping. Fluid inclusions containing H₂O-CO₂-NaCl are common in many geologic environments and knowing the salinity of these inclusions is important to interpret PVTX properties of the fluids. A technique that combines Raman spectroscopy and microthermometry of individual inclusions was developed to determine the salinity of these inclusions. In order to determine the salinity, the pressure and temperature within the inclusion must be known. The pressure within the inclusions is determined using the splitting in the Fermi diad of the Raman spectra of the CO₂ at the clathrate melting temperature. Applying the technique with to synthetic fluid inclusions with known salinity suggests that the technique is valid and useable to determine salinity of H₂O-CO₂-NaCl fluid inclusions with unknown salinity.

Abstract:
Mineral inclusions in non-fibrous and fibrous diamonds from an Archean metaconglomerate deposit in Wawa, Ontario, Southern Superior craton were studied to characterize the compositional and thermal state of the lithospheric mantle from the Archean to present day. Electron microprobe analysis of Wawa non-fibrous diamonds shows large inclusions of Cr-pyrope, Mg-chromite, olivine, and enstatite indicating harzburgitic parent rock. Wawa fibrous diamonds host microinclusions of pyrope and olivine of predominantly lherzolitic assemblage. Thermobarometry calculations for non-fibrous diamonds yield temperatures and pressures consistent with formation in a cool, cratonic root reaching to a minimum depth of 190 km with a geotherm between 39-41 mW/m², located beneath the Southern Superior province during the Archean. Comparison to results from xenoliths in nearby post-Archean kimberlites, and to modern geophysics, indicates heating and thinning of the cratonic root. This effectively destroyed the diamondiferous portion of the lithospheric mantle, as early as 1.1 Ga in some areas of the Southern Superior, through tectonic erosion during amalgamation of terranes to the protocraton. Diamond inclusion analysis for Wawa fibrous diamonds and datasets for non-fibrous and fibrous diamonds from Diavik, Ekati (Panda kimberlite), and Koffiefontein (South Africa) reveal metasomatic trends of mantle rock evolution due to the influx of K-rich hydrous carbonatitic fluid related to fibrous diamond precipitation. Thermometry for fibrous diamond inclusions yields temperatures of 580-1030°C. Low formation temperatures, paired with the alkali-rich and hydrous nature of the metasomatic agent, result in subsolidus diamond growth in the absence of melting or thermal disturbance of the mantle. Fibrous diamond growth, previously linked to kimberlite generation, may be a temporally distinct and genetically independent event, as suggested by long mantle residence times for fibrous diamonds and contrasting chemistry of fibrous diamond fluid and kimberlites. This would make metasomatism associated with formation of fibrous diamonds a “cratonic root-friendly” process that would not have played any part in the destruction of the Southern Superior lithospheric root.

Abstract:
The properties of composite materials in which spherical inclusions are embedded in a matrix of some kind, have been studied for many decades and many analytical models have been developed which measure these properties. There has been a steady progression in the complexity of models over the years, providing greater insight into the nature of these materials and improving the accuracy in the measurement of their properties. Some of the properties with which this thesis is concerned are, the elastic, thermal and electrical properties of such composites. The size of the spherical inclusion which acts as the reinforcing phase, has a major effect on the overall properties of composite materials. Once an inclusion is embedded into a matrix, a third region of different properties between the inclusion and matrix is known to develop which is called the interphase. It is well known in the composite community that the smaller the inclusion is, the larger the interphase region which develops around it. Therefore, with the introduction of nanoparticles as the preferred reinforcing phase for some composites, the interphase has a major effect on its properties. It is the aim of this thesis to consider the role of the interphase on the properties of composites by modeling it as an inhomogeneous region. There is much scientific evidence to support the fact that the interphase has an inhomogeneous nature and many papers throughout the thesis are cited which highlight this. By modeling the inhomogeneous properties by arbitrary mathematical functions, results are obtained for the various properties in terms of these general functions. Some specific profiles for the inhomogeneous region are considered for each property in order to demonstrate and test the models against some established results.

Abstract:
As condições de pressão e temperatura existentes no evento tectônico que atuou na zona de fold-and-thrust da margem oeste do Cráton do São Francisco foram estimadas com base em estudos estruturais, microestruturais, petrográficos e de inclusões fluidas de veios sintectônicos. A presença de veios de diferentes gerações na zona de fold-and-thrust é evidenciada por fluidos atuando em diferentes cenários de paleoestresse ao longo da história deformacional da área. A área é composta por rochas do Grupo Bambuí fracamente deformadas que registram condições de metamorfismo que variam de diagênese a fácies subxisto verde. Dois eventos tectônicos foram identificados através da disposição geométrica dos veios e da superfície dobrada: (i) uma compressão principal NE-SW (D1) com \'sigma\'1 subhorizontal de orientação SW e \'sigma\'3 sub-vertical, relacionado à formação de veios sintectônicos sub-horizontais de orientação NW formados em condições que atingiram pelo menos 140- 160°C e pressões em torno de 200-363 MPa; (ii) uma compressão posterior NW-SE (D2) com \'sigma\'1 sub-horizontal de orientação NW e \'sigma\'3 também sub-horizontal de orientação NE. Estão relacionados à D2 a formação de veios sintectônicos sub-verticais paralelos à clivagem, formados nas mesmas condições mínimas de temperatura de 140-160°C e pressões entre 181- 295 MPa. A indicação de flutuações na pressão durante esses eventos desempenhou um papel crucial, pois os fluidos influenciam significativamente os processos mecânicos, os mecanismos de deformação e as reações químicas que operam em cinturões de fold-andthrust. Os fluidos apresentam composição formada por H2O-NaCl-CaCl2, onde o processo de mistura de diferentes fontes de fluidos (metamórficas e meteóricas) é evidenciado pela tendência evolutiva de temperaturas de homogeneização e salinidades, resultando em alguma variação na salinidade (12 contra 4% em peso equivalente de NaCl para os veios subhorizontais e para os paralelos à clivagem, respectivamente). Este trabalho confirma que a combinação entre a reconstrução do paleoestresse e o estudo de inclusões fluidas podem fornecer informações fundamentais sobre a relação entre o fluxo de fluidos e a tectônica de terrenos orogênicos, contribuindo para o conhecimento científico sobre a evolução deformacional/metamórfica do Grupo Bambuí e, consequentemente, da zona de fold-andthrust da margem ocidental do Cráton do São Francisco.
P-T conditions existing at the tectonic event that acted at the fold-and-thrust zone of the western margin of the São Francisco Craton were estimated on the basis of structural, microstructural, petrographic and fluid inclusion study of syntectonic veins. The presence of veins of different generations in the fold-and-thrust zone is evidenced by fluids operating at different scenarios of paleostress throughout the deformation history. The area are composed of weakly deformed rocks of the Bambuí Group recording a metamorphism with conditions ranging from diagenetic to sub-greenschist facies. Two tectonic events were identified by vein geometric arrangement and folded surface, a major early NE-SW compression (D1 - \'sigma\'1 subhorizontal SW-trending and \'sigma\'3 subvertical), related with subhorizontal NW-trending syntectonic veins formed at conditions that have reached at least 140°C and pressures around 200-363 MPa; and later NW-SE compression (D2 - \'sigma\'1 subhorizontal NW-trending and \'sigma\'3 subhorizontal NE-trending), related with subvertical syntectonic cleavage-parallel veins formed at the same range of temperature and pressures between 181-295 MPa. Indication of fluctuations in pressure during these events played a crucial role as fluids significantly influence the mechanical processes, deformation mechanisms and chemical reactions that operate in fold-thrust belts. Fluids show H2O-NaCl-CaCl2 composition where mixing process of different fluids sources (metamorphic and meteoric) are evidenced by evolutive trending of homogenization temperatures and salinities resulting in some variation in salinity (12 against 4 wt.% NaCl eq. for subhorizontal and cleavage-parallel veins respectively). This research confirms that combine the reconstruction of the paleostress states and fluid inclusion studies can provide fundamental information of relationship between fluid flow and tectonic of orogenic terrains contributing to the scientific knowledge about the deformational/metamorphic evolution of the Bambuí Group and the fold-and-thrust zone of the western margin of the São Francisco Craton.

Abstract:
Dans l’étude de la diagenèse des formations silico-clastiques ou carbonatées, il est souvent difficile de contraindre la température et l’âge des différents épisodes de cimentation ou de recristallisation. Le premier objectif de ce travail de thèse était de tester le potentiel de deux outils isotopiques récents (le géothermomètre des « clumpedisotopes » Δ47 et le géochronomètre U-Pb par analyse ponctuelle sur lame mince) dans le cadre de l’étude de la diagenèse des carbonates. Le deuxième objectif était de préciser l’histoire diagénétique, thermique, ethydrogéologique des réservoirs carbonatés du bassin de Paris. Pour atteindre ces deux objectifs, nous avons étudié des ciments de calcite et dolomite collectés dans les calcaires du Jurassique Moyen du dépocentre du bassin de Paris. La bonne caractérisation pétrographique et sédimentologique de ces échantillons, et le couplage entre les géothermomètres Δ47 et inclusions fluides, nous ont permis d’accéder à plusieurs informations de premier ordre. Premièrement, nous montrons que le Δ47 permet de reconstruire simultanément et précisément la température de formation des ciments diagénétiques dans la gamme 60-100°C (avec une précision de ~3-5°C) et la composition isotopique en oxygène des fluides (δ18Owater) à partir desquels ces ciments ont précipités (avec une précision de ~ 1‰). Deuxièmement, nous présentons une amélioration des connaissances de l’histoire thermique et des périodes de paléo-circulation des fluides à l’échelle régionale dans le bassin de Paris. Notamment, le croisement du géothermomètre Δ47 avec la méthode de datation U-Pb nous a permis pour la première fois de poser des contraintes thermo-chronologiques absolues sur l’ensemble des phases de circulations de fluides étudiées. Plus largement, ce couplage Δ47 /(U-Pb) inédit dévoile un champ d’application nouveau en thermo-chronologie de basse température (10-100°C). Nous anticipons que ce travail initie de nombreuses applications pour l’étude des histoires thermiques des bassins sédimentaires, via l’analyse de la diagenèse des carbonates
Diagenesis studies of both siliciclastic and carbonate rock units face the difficulty of constraining the temperature and age of the successive episodes of mineral crystallization. The first objective of this PhD work was to test the potential of two recent isotopic tools (the "clumped isotopes" Æ47 geothermometer and the laser ablation U-Pb geochronometer ) to integrate conventional carbonate diagenesis studies. The second objective was to reconstruct the diagenetic, thermal, and hydrogeological histories of the Middle Jurassic carbonate reservoirs of the Paris Basin. To achieve these goals, we studied calcite and dolomite cements mostly collected in the basin subsurface (exploration cores). The good petrographical and sedimentological characterization of the studied samples, together with the analysis of fluid inclusions and ?47 thermometry for determining the temperature and the chemical and isotopic compositions of the mineralizing fluids, allowed us to reach several first-order information. First, we show that Æ47 allows to simultaneously and precisely reconstruct the formation temperature of diagenetic cements in the range 60-100 ¡C (with an accuracy of ~ 3-5 ¡C) and the oxygen isotopic composition of the parent fluids (d18Owater) with a precision of ~ 1 ä. Secondly, this work improves our knowledge on the thermal history and past fluid-flows occurring at the basin scale. In particular, the coupling of the Æ47 thermometer with the U-Pb chronometer permitted for the first time to set absolute thermo-chronological constraints on every fluid-flow episodes investigated. More broadly, this unprecedented Æ47/(U-Pb) coupling reveals a new field of application in the low-temperature thermo-chronology field (10-100 ¡C). We anticipate that this pioneer thermo-chronological approach will induce many future applications in the study of sedimentary basins via carbonate diagenesis studies

Abstract:
A Formação Serra Alta é constituída por uma sequência de folhelhos e siltitos cinza supostamente de origem marinha. Esta unidade é uma potencial rocha geradora de hidrocarbonetos e zona preferencial para alojamento de sills associados ao magmatismo Serra Geral. Visando a caracterização do potencial gerador de hidrocarbonetos, a evolução térmica e os paleofluidos diagenéticos da Formação Serra Alta, foram realizadas medidas de concentração de carbono orgânico total (COT) e hidrogênio (H) em amostras coletadas em afloramentos e estudos isotópicos e de inclusões fluidas em materiais diagenéticos. Os teores de carbono orgânico total (COT) e hidrogênio (H) para as amostras de folhelhos da Formação Serra Alta estão situados entre 0,1 e 0,5% e entre 0,24 e 3,20%, respectivamente. Os dados microtermométricos apresentaram temperaturas de homogeneização (Th) que variaram de 55 a 220°C, temperaturas eutéticas (Te) de -57,5 a -49,5ºC (sistema H2O + NaCl + CaCl2) e temperaturas de fusão do gelo (Tfg) de -2,5 a 1,0°C, indicativas de salinidades baixas, entre 0 e 4,2% em peso de NaCl equivalente. Os resultados de \'\'delta\'\' POT.13\'\'C IND.PDB\' e \"delta\'\'POT.18\' \'O IND.PDB\' das amostras de veio e cimento de calcita demonstram valores negativos (%o), tanto para \'delta\'\'POT.13\' C quanto para \'delta\'\'POT.18 O. Enquanto os valores de \'delta\'\'POT.13\'\' C IND.PDB\' do cimento dos folhelhos da Formação Serra Alta variam entre -8,6 e -2,3%o, os veios de calcita apresentam uma estreita faixa de valores entre -5,1 e -3,7%o. Os teores de COT indicam potencial de geração de óleo e gás considerado baixo para os folhelhos da Formação Serra Alta. As características das inclusões (monofásicas associadas a bifásicas com pequena variação nas proporções volumétricas entre as fases), as salinidades relativamente constantes associadas às grandes variações em Th são indicativos de aprisionamento em zona freática de baixa temperatura (<50°C) com posterior reequilíbrio térmico causado por stretching devido ao soterramento e à presença de corpos ígneos. Os pleofluidos aquosos aprisionados como inclusões em zona de baixa temperatura, antes do pico térmico do Cretáceo, explicariam a ausência de inclusões fluidas primárias de hidrocarbonetos nos veios de calcita. As Th acima de 150ºC indicam elevada maturidade térmica alcançada pela Formação Serra Alta em função do soterramento e do magmatismo Serra Geral. Estes resultados são semelhantes aos obtidos para as formações adjacentes (Irati e Teresina) à Formação Serra Alta. Valores de \'delta\'\'POT.13\'\'C IND.PDB\' e \'delta\'\'POT.18\'\'O IND.PDB\' para o cimento carbonático dos folhelhos, revelam duas gerações ou duas fases de precipitação distintas da calcita. A primeira geração compatível com assinatura isotópica próxima ao fluido marinho original (\'delta\'\'POT.13\' C entre -2,3 e -4,6%o e \'delta\'\'POT.18\'O entre -7,6 e 1,4%o) e a segunda geração compatível com assinatura isotópica de um fluido diagenético de origem meteórica (\'delta\'\'POT.13\' C entre -6,2 e -8,6%o e \'delta\'\'POT.18\'O entre -8,4 e -4,1%o). Assim, a hipótese de origem meteórica para os fluidos percolantes nas fraturas corrobora a salinidade baixa registrada nas inclusões fluidas dos veios de calcita, mas com alguma influência ou modificação por meio de fluidos pré-existentes, que interagiram com carbonatos marinhos das unidades estratigráficas adjacentes (formações Irati e Teresina) à Formação Serra Alta.
The Serra Alta Formation at the eastern border of the Paraná Basin consists of a sequence of gray shales and siltstones presumably of marine origin. This unit is a potential source rock for hydrocarbons and preferred area for hosting sills associated with the early Cretaceous Serra Geral magmatism. In order to characterize the hydrocarbon generation potential, the thermal evolution and diagenetic paleofluids of the Serra Alta Formation, were performed measurements of concentration of total organic carbon (TOC) and hydrogen (H), in shale samples collected from outcrops, and isotope and fluid inclusions studies on diagenetic calcite. The total organic carbon (TOC) and hydrogen (H) contents for shale samples of the Serra Alta Formation lie between 0.1 and 0.5% and between 0.24 and 3.20% respectively. The microthermometry data show homogenization temperature (Th) ranging from 55 to 220°C, eutectic temperature (Te) from -57.5 to -49.5°C (H2O + CaCl2 + NaCl system) and ice melting temperatures from -2.5 to 1.0°C, indicative of low salinity between 0 and 4.2 wt. % of NaCl equivalent. \'delta\'\'POT.13\'\'IND.CPDB\' and \'delta\'\'POT.18\'O IND.PDB\' results from samples of calcite cement and veins demonstrate negative values (%o), both for \'delta\'\'POT.13\'C and for \'delta\'\'POT.18\'O. While the values \'delta\'\'POT.13\'C IND.PDB\' cement of the Serra Alta Formation shales vary between -8.6 and -2.3%o, the calcite veins have a narrow range of values between -5.1 and -3.7%o. The TOC content indicate that the shales of the Serra Alta Formation have low potential for oil and gas generation. The association of one-phase and two-phase fluid inclusions with small variations in volumetric ratio between phases and the relatively constant salinity associated with large variations in Th are indicative of fluid trapping in low temperature (<50°C) groundwater zone, with subsequent thermal reequilibrium caused by stretching due to burial and the presence of igneous bodies. The fluid trapping at this low temperature zone, before Cretaceous thermal peak, would explain the absence of hydrocarbon primary fluid inclusions in the calcite veins. Temperatures of homogenization higher than 150ºC indicate high thermal maturity achieved by the Serra Alta Formation due to burial and the Serra Geral magmatism. These results are similar to those obtained for the adjacent formations (Irati and Teresina) of the Serra Alta. \'delta\'\'POT.13\'C IND.PDB\' and \'delta\'\'POT.18\'O IND.PDB\' values for carbonate cement reveal two generations or two distinct phases of calcite precipitation. The first generation is compatible with isotopic signature close to the original marine carbonate (\'delta\'\'POT.13\'C between -2.3 and -4.6%o and \'delta\'\'POT.18\'O between -7.6 and 1.4%o) and the second generation is compatible with isotopic signature of a diagenetic fluid of meteoric origin (\'delta\'\'POT.13C between -6.2 and -8.6%o and \'delta\'\'POT.18\'O between -8.4 and -4.1%o). Thus, the meteoric origin for the paleofluids percolating in fractures corroborates the low salinity recorded in fluid inclusions from veins of calcite, but with some influence of paleofluids, which interacted with marine carbonates of stratigraphic units (Irati and Teresina formations) adjacent to the Serra Alta Formation.

Abstract:
This thesis demonstrates that geological setting, depositional facies, open system flux of hot basinal brines and descending of shallow waters have a strong impact on the distribution of the diagenetic alterations within continental and paralic/shallow marine sandstones which in turn control the quality and heterogeneities of the reservoirs. Geological setting controls the mineralogical and textural maturity of sandstone, whereas depositional facies control the pore water chemistry (marine, brackish or meteoric), sedimentary texture and sand body geometry. Eogenetic alterations in the fluvial deposits are dominated by precipitation of infiltrated clays, kaolinitization of detrital silicates, whereas the shallow marine deposits are dominated by precipitation of early calcite and kaolinite. Conversely mesogenetic alterations are dominated by clay minerals transformation, quartz overgrowths and Ferroan- carbonates, barite and anhydrite. Flux of hot basinal brines is evidenced by precipitation of mesogenetic minerals that lack of internal sources (e.g. barite, anhydrite and ferroan carbonate cements), which is evidenced by: (1) restricted occurrence of these minerals in downthrown blocks. (2) The high fluid inclusion homogenization temperatures (Th) of quartz overgrowths (Th > 110-139°C), and carbonate cements (T > 80-140°C), which also have light δ18OV-PDB(-17.6‰ to -6.7‰). Flux of hot basinal brines is further evidenced by occurrence of saddle Fe-dolomite along stylolites. Fluid inclusion microthermometry further revealed a dramatic shift in pore- water chemistry from NaCl dominated brines during precipitation of quartz overgrowths to NaCl-CaCl2 dominated brines during cementation by Fe-dolomite. Presence of mixed brine (NaCl+CaCl2) systems in the fluid inclusions suggests flux of descending waters, which have circulated in the overlying carbonate-evaporite successions. The restricted occurrence of oil- filled inclusion to quartz overgrowths and methane to Fe-carbonate cements suggest migration of oil during precipitation by quartz and migration of methane during precipitation by Fe- carbonate cements. The extensive mesogenetic cements in the down thrown blocks is attributed to flux of basinal brines along deep seated faults, i.e. open system diagenesis. Integration of fluid inclusion microthermometry, isotopes, Raman spectrometry and thermal tectonic evolution of basins are essential techniques for unraveling the evolution of basinal fluids, cementation conditions and relative timing of hydrocarbons migration.

Abstract:
AbstractwIRA has been shown to reduce extracellular chlamydial forms and intracellular chlamydial inclusions in different cell culture infection models, and similarly on different human or animal chlamydial species. Repeated wIRA applications increase the efficacy of treatment in vitro, and in vivo in a guinea pig ocular model of inclusion conjunctivitis. The guinea pig model reflects the human ocular disease trachoma, the most common cause of infectious blindness worldwide which is caused by ocular strains of Chlamydia trachomatis. In this model, ocular wIRA treatment reduces conjunctival chlamydial load and ocular pathology. First insights into the mechanisms of anti-chlamydial activity indicate the involvement of both thermal and non-thermal effects. Interestingly, wIRA treatment of non-infected cells renders them more resistant to subsequent chlamydial infection, suggesting cell-related mechanisms that might involve cytochrome C. Further studies envisage the refinement of wIRA treatment protocols, the enhancement of anti-chlamydial activity by adding photodynamic substances, and characterization of the mechanisms underlying the therapeutic benefit of wIRA.

Abstract:
Increasing power dissipation in today’s microprocessors demands thermal interface materials (TIMs) with lower thermal resistances. The TIM thermal resistance depends on the TIM thermal conductivity and the bond line thickness (BLT). Carbon Nanotubes (CNTs) have been proposed to improve the TIM thermal conductivity. However, the rheological properties of TIMs with CNT inclusions are not well understood. In this paper, the transient behavior of the BLT of the TIMs with CNT inclusions has been measured under controlled attachment pressures. The experimental results show that the impact of CNT inclusions on the BLT at low volume fractions (up to 2 vol%) is small; however, higher volume fraction of CNT inclusions (5 vol%) can cause huge increase in TIM thickness. Although thermal conductivities are higher for higher CNT fractions, a minimum TIM resistance exists at some optimum CNT fraction for a given attachment pressure.

Abstract:
Abstract It was recently discovered that inclusions and other types of inhomogeneities can be nondestructively detected by thermoelectric measurements in an entirely non-contact way by using high-sensitivity magnetometers to sense the weak thermoelectric currents around the affected region when the specimen is subjected to directional heating or cooling. This paper presents theoretical models capable of predicting the magnetic field produced by thermoelectric currents around inclusions under external thermal excitation. We investigated how the magnetic signal to be detected depends on (i) the relevant physical properties of the host and the inclusion, (ii) the size of the inclusion, (iii) the polarization of the magnetometer, (iv) the lift-off distance of the magnetometer from the specimen, and the (v) direction and (vi) strength of the external heating or cooling applied to the specimen. The presented analytical model is numerically evaluated for comparison to experimental results that were obtained by measuring the magnetic field produced by thermoelectric currents around surface-breaking spherical tin inclusions in copper under external thermal excitation for different lift-off distances between the sensor and the surface of the specimen. The diameter of the inclusions and the lift-off distance varied from 2.4 to 12.7 mm and from 12 to 20 mm, respectively. A fairly modest 0.7 °C/cm temperature gradient in the specimen produced peak magnetic flux densities ranging from 1 to 250 nT, that could be easily measured by a commercial fluxgate magnetometer. The experimental results were found to be in very good agreement with our analytical predictions.

Abstract:
Abstract Linearly thermoelastic composite media are treated, which consist of a homogeneous matrix containing a statistically homogeneous random set of ellipsoidal uncoated or coated inclusions. Effective properties (such as compliance, thermal expansion, stored energy) as well as both first and second statistical moments of stresses in the components are estimated for the general case of nonhomogeneity of the thermoelastic inclusion properties. The micromechanical approach is based on Green’s function techniques as well as on the generalization of the “multiparticle effective field” method (MEFM), previously proposed for the estimation of stress field averages in the components. The application of the theory is demonstrated by calculating overall strength surfaces of composite materials. The influence of the coating is analyzed by the use of both the assumption of homogeneity of the stress field in the inclusion core and of the thin-layer hypothesis. Let us consider statistically uniform random set of coated ellipsoidal inclusions having all the same form, orientation and mechanical properties. We are using the main hypothesis of many micromechanical methods, according to which each inclusion is located inside a homogeneous so-called effective field. It is shown, in the framework of the effective field hypothesis, that from a solution of the pure elastic problem (with zero stress free strains) for the composite the relations for effective thermal expansions, stored energy and average thermoelastic strains inside the components can be found. This way one obtains the generalization of the classical formulae by Rosen and Hashin, which are exact for two-component composites. The proposed theory is applied to the example of composites reinforced with ellipsoidal inclusions with thin inhomogeneous (along inclusion surface) coatings. For a single coated inclusion the micromechanical approach is based on the Green function technique as well as on the interfacial Hill operators. Functionally graded materials are considered, which consists of a homogeneous matrix and a statistically inhomogeneous random set of ellipsoidal inclusions. The hypothesis of effective field homogeneity near the inclusions is used, non-local effects in the constitutive relations are not considered. Non-local dependencies of local effective elastic properties as well as of conditional averages of the stresses in the components on the local concentration of the inclusions are demonstrated. Numerical results are represented for spherical clusters of spherical inclusions. In the interior of a large cluster, sufficiently far away from the boundary, the local effective moduli coincide with the isotropic effective moduli for the statistically homogeneous medium. However, near the boundary of the cluster the tensors of the effective moduli lose isotropy, i.e., they become transversally isotropic and vary significantly within the boundary layer, the thickness of which equals approximately two diameters of the inclusions (non-local boundary layer effect). The character of the dependence of the effective elastic moduli varies (i.e., they increase or decrease monotonically or non-monotonically with the distance from the boundary of the cluster) with the variation of the cluster size (scale effect). Both average meso stresses and average micro stresses in the phases are estimated along the radius of the cluster.

Abstract This paper provides results from experimental studies with regard to novel, thermally sprayed coatings for tribological applications, which consist of mechanical mixtures of cast iron powders (2.16% by weight C and 5.18% by weight Si) and solid lubricant (calcium fluoride or iron oxide) produced in an amount of 10 to 20% by volume. It was established that a basic phase of initial cast iron powder and detonation coatings is gamma-Fe and it is alpha-Fe in plasma coatings. Oxide inclusions which are products of cast iron oxidation are observed in coatings structure. Metallographic investigations showed an uniform distribution of solid lubricant inclusions in a metallic-matrix of coatings. Tribotechnical tests of coatings containing 20 vol. % calcium fluoride carried out in conditions of room temperature indicated that the best antifriction properties were obtained for coatings with calcium fluoride additions which were sprayed by supersonic air-gas plasma method.

Abstract:
The results obtained from the modeling of thermal partial oxidation of kerosene based Jet-A fuel are presented using one dimensional chemical modeling. Two detailed kinetic models for alkenes chemistry ranging between C8 to C16 were evaluated and compared against experimental data of thermal partial oxidation of Jet-A fuel. The key difference between these two kinetic models was the inclusion of model for soot formation reactions. Chemical modeling was performed using dodecane to represent Jet-A fuel. The results showed that the model with soot reactions was significantly more accurate in predicting reformate products from Jet-A. In particular, the formation of carbon monoxide, methane and acetylene closely followed the experimental data with the model that included soot formation reactions. The results revealed that the soot formation reactions promoted the smaller hydrocarbons to decompose via the alternate kinetic pathways and from additional radical formation. The results also reveal that the inclusions of soot formation reactions are critical in the modeling of thermal partial oxidation of fuels for fuel reforming.

Abstract:
A comparison between reported analytical results with experimental data of the magnetic flux density produced by weak thermoelectric currents around cylindrical inclusions of elliptical cross-section embedded in a copper matrix under external thermal excitation for different aspect ratios b/a of the elliptical inclusions is presented. The aspect ratio of the elliptical cylindrical inclusions varied from 0.5 to 3.250. By changing the aspect ratios b/a of the elliptical inclusions, a wide range of real situation such as slender inclusions, cracks and even porosity can be simulated. A fairly modest 2.3°C/cm temperature gradient in the specimen produced magnetic flux densities ranging from 2 to 100 μT at 2 mm lift-off distance between the tip of the magnetometer probe and the specimen. The experimental magnetic field distribution illustrated the potential for the non contacting thermoelectric technique to detect and characterize metallic inclusions of different geometries based on their magnetic signature.
