Abstract:
Three kinds of aluminum foam of different pore sizes were prepared with a tailor-made low-pressure infiltration device. CaO granules in three sizes (0.45~0.71mm,0.71~090mm and 1.25~1.60mm) were selected as infiltrating agents. The processing parameters were as follows: granules preheat temperature of 700 °C,infiltration pressure of 0.04 MPa and aluminum liquid temperature of 720 °C. In order to improve the removal performance and porosity, mixture of CaO powder of finer than 300 mesh and pure alcohol was mixed uniformly with granules, which made the slurry-coating granules conformal contacts rather than point contacts as in the traditional infiltration method. The testing results show that among all aluminum foam specimens tested with transfer function methods, two kinds have high sound absorption coefficient in low frequency (250~1600Hz).

The infiltration capacity is a decisive factor to ensure the effective operation of groundwater reservoir. This study analysis the infiltration capacity variation and its factors based on the data of infiltration test in Hutuo River Groundwater Reservoir. The results show that, there is a high infiltration rate in the alternative field, the infiltration rate is 3m/d, and decreased by 50% as 1.4m/d 6 days later; the contrast of soil permeability, vertical permeable rate of aerial zone, permeability of saturation zone between pre-test and post-test show that, the vertical permeable rate of aerial zone and permeability of saturation zone vary little, the descend of soil permeability is the main factor of the infiltration capacity decay.

Abstract:
At the experimental base of Tianjin Agricultural University, the infiltration process of water was measured by double - ring infiltration instrument at six points. Horton，Philip and Kostiakov-lewis (K-l) infiltration models were fitted with the infiltration data measured and the parameters were correspondingly obtained. Six sets of parameters of the corresponding infiltration model were obtained, and six sets of parameters were used for statistical analysis. The reasonable number of points of the corresponding model was obtained. Then, the statistical analysis of the cumulative infiltration amount was used to obtain the variation of the number of reasonable points in the three models with time. The results show that the imitative effect of accumulative infiltration water and time in K-l model is the best, and the curve of reasonable test points determined by K-l model with time is located under the other two models; The reasonable number of points determined by the parameter K in the K-l model is the least and most reasonable. In view of this, the number of reasonable points was determined by using the parameter K in the K-l model.

Abstract:
Infiltration is customarily assumed to increase the heating and cooling load of a building by an amount equal to the mass flow rate of the infiltration times the enthalpy difference between the inside and outside air—with the latent portion of the enthalpy difference sometimes neglected. Calorimetric measurements conducted on a small test cell with measured amounts of infiltration introduced under a variety of conditions show convincingly that infiltration can lead to a much smaller change in the energy load than is customarily calculated; changes as small as 20 percent of the calculated value have been measured in the cell. The data also suggest that the phenomenon occurs in full-sized houses as well. Infiltration Heat Exchange Effectiveness (IHEE), ε, is introduced as a measure of the effectiveness of a building in “recovering” heat otherwise lost (or gained) due to infiltration. Measurements show that ε increases as: (a) flow rate decreases; (b) flow path length increases; (c) hole/crack size decreases. There is a clear correlation between large values of ε and large values of the exponent, n, so fan pressurization results may be useful in predicting ε for buildings.

Abstract Previous studies have shown declining rates of pulpal anesthesia over 60 minutes when a cartridge of 4% articaine is used with 1∶100,000 epinephrine for buccal infiltration in the mandibular first molar. The authors conducted a prospective, randomized, single-blind, crossover study comparing the degree of pulpal anesthesia obtained with 2 sets of mandibular first molar buccal infiltrations, given in 2 separate appointments, to 86 adult subjects: an initial infiltration of a cartridge of 4% articaine with 1∶100,000 epinephrine plus a repeated infiltration of the same anesthetic and dose given 25 minutes following the initial infiltration versus an initial infiltration of a cartridge of 4% articaine with 1∶100,000 epinephrine plus a mock repeated infiltration given 25 minutes following the initial infiltration. The authors used an electric pulp tester to test the first molar for anesthesia in 3-minute cycles for 112 minutes after the injections. The repeated infiltration significantly improved pulpal anesthesia from 28 minutes through 109 minutes in the mandibular first molar. A repeated infiltration of a cartridge of 4% articaine with 1∶100,000 epinephrine given 25 minutes after an initial infiltration of the same type and dose of anesthetic significantly improved the duration of pulpal anesthesia, when compared with only an initial buccal infiltration, in the mandibular first molar.

Abstract:
One of the primary factors for generating heating and cooling loads in apartment houses is infiltration. However, the evaluation method for infiltration rates has not been well established for the apartment houses in Korea. The existing method measures air change per hour of a house at 50 Pa (ACH50) and divides it by the leakage–infiltration ratio, N = 20, as suggested by the Lawrence Berkeley National Laboratory (LBL). In this study, a method to evaluate the average infiltration rate of an apartment house using blower door tests and simulations is suggested. Six sets of blower door tests were conducted, and the measurement data were used to estimate the flow coefficients and pressure exponents of all infiltration routes. The values were used as the input data for EnergyPlus to calculate the natural air change per hour values (ACHn) of two households. The calculated ACHn values were compared to the ACHn values calculated using the LBL method, which is commonly used in Korea. Through this process, the limitations of applying the LBL method to calculate the ACHn values in Korea were investigated. The results show that investigating the proper leakage–infiltration ratio is required for Korea. The method suggested in this study can be used to determine the proper leakage–infiltration ratio for apartment houses.

Abstract:
Le contrôle de la sûreté des ouvrages hydrauliques est l’une des grandes priorité dans le domaine du génie civil et de l’ingénierie hydraulique. Durant sa vie, un ouvrage est soumis à des sollicitations variables hydromécaniques, physicochimiques et climatiques qui contribuent à son éventuelle détérioration. Parmi les phénomènes qui en résultent, l’érosion des sols sous toutes ses formes représente un enjeu majeur à comprendre, maîtriser et empêcher. L’objectif de ce travail est d’étudier l’érosion des sols par le Jet Erosion Test. La première partie est consacrée à la description des dispositifs expérimentaux, surtout le Jet Erosion Test (JET) développé à l’Ecole Centrale Paris permettant de mesurer directement quelques paramètres d’érosion. A partir des résultats du JET, à l’aide d’une loi d’érosion empirique, nous déduisons la contrainte de cisaillement critique, le coefficient d’érosion, la profondeur d’érosion d’équilibre. La deuxième partie du travail est consacrée à l’étude de l’influence des paramètres de compactage sur l’infiltration de l’eau et la résistance du sol, en utilisant le pénétromètre. Dans les troisième et quatrième parties, nous étudions l’influence des propriétés géotechniques du sol et celle des paramètres d’essai sur les paramètres d’érosion du sol. Les résultats obtenus montrent que les paramètres d’érosion sont influencés non seulement par les propriétés géotechniques du sol mais aussi par les paramètres d’essai. La dernière partie présente la synthèse entre les résultats des essais de pénétromètre et ceux des essai de JET, et tente de relier les paramètres d’érosion avec les propriétés géotechniques du sol
Control of the safety of hydraulic structures is a major priority in the field of civil and hydraulic engineering. During its life, the hydraulic structure is submitted to variable hydromechanical, physicochemical and climatic loads that may contribute to its possible failure. Among the resulting phenomena, soil erosion under all its forms is a major challenge which it is important to understand, control and prevent. The objective of this work is to study soil erosion by the Jet Erosion Test. The first part is devoted to the description of the experimental devices, especially the Jet Erosion Test (JET) developed at the Ecole Centrale Paris to directly measure some erosion parameters. From the results of JET, using an empirical erosion law, we deduce the critical shear stress, the erosion coefficient, the equilibrium scour depth. The second part of this work is devoted to the study of the influence of compaction parameters on water infiltration and soil strength, using the penetrometer. In the third and fourth parts, we study the influence of the geotechnical properties of soil and of the test parameters on the erosion parameters of soil. The obtained results show that the erosion parameters are influenced not only by the geotechnical properties of soil but also by the test parameters. The final section presents a synthesis of the results of penetrometer tests and JET tests, and attempts to link the erosion parameters with the geotechnical properties of soil

Abstract:
This work characterizes the material properties of carbon infiltrated carbon nanotube (CI- CNT) structures. The impacts of temperature, time, and hydrogen flow rates on the material prop- erties of modulus of elasticity and strength are examined and compared. Carbon infiltration levels are assessed through the use of SEM images to determine which parameters give the highest level of infiltration. Through the use of SEM, carbon capping is observed on samples infiltrated for longer times at 900 and 950◦ C, suggesting that the samples are not being infiltrated during the entire desired infiltration period at these temperatures. The highest material properties of modulus and strength were reached when infiltrating the carbon nanotube forests for 150 mins at 850◦ C with hydrogen flowing at 311 sccm (0.0115 m/s). With these parameters, a modulus of 20.4 GPa and strength of 289.8 MPa were attained. The poorest results were seen when the samples were infiltrated at 800◦ C, and is therefore not recommended as an infiltration temperature if high mod- ulus and strength are desired. Density is correlated to strength and modulus and it is seen that there is a strong correlation between higher strength and modulus with higher density.

A determinação dos parâmetros hidráulicos não saturados em laboratório nem sempre representa efetivamente as situações observadas em campo, principalmente devido ao erro causado pelo efeito de escala. Nesse sentido, inúmeros ensaios de campo vêm sendo desenvolvidos, fazendo o uso de medidas de carga de pressão no tempo, para a determinação das propriedades hidráulicas não saturadas. No presente estudo, foi utilizado o ensaio de campo proposto por Velloso (2000), denominado Ensaio de Infiltração Monitorada (EIM). Neste ensaio é mantida uma carga constante, utilizando um permeâmetro tipo Gueplh, sendo monitorada, com o auxílio de um tensiômetro, a variação da sucção ocasionada pela frente de infiltração. Quando a variação da sucção no solo torna-se constante e próxima a zero, o ensaio atingiu, portanto, a condição de fluxo permanente, podendo-se assim finalizar o teste. Os parâmetros do solo e os respectivos parâmetros do modelo de Van Genuchten (1980), os quais descrevem a curva de saturação versus o potencial mátrico, são obtidos matematicamente, através da resolução do problema inverso. Nesse sentido, o objetivo principal do presente trabalho é realizar uma avaliação detalhada dos procedimentos numéricos e experimentais para uso no Ensaio de Infiltração Monitorada (EIM), seguindo as diretrizes e recomendações apontadas nos estudos anteriormente realizados. Desta forma, buscou-se um melhor entendimento do EIM, e para isto, foram realizadas: análises comparativas com resultados de ensaio de laboratório do tipo papel filtro; foi adicionado o monitoramento de umidade de solo durante o EIM; e foram utilizados diferentes métodos de estimativa de parâmetros. Os ensaios apresentados no presente estudo foram realizados em cinco áreas do Estado do Rio de Janeiro.
The determination of unsaturated hydraulic parameters in laboratory tests is not always represents as observed on the field, especially because of the presence of errors caused by the scale factor. So, several field tests have been developed using suction measures with time for a determination of the unsaturated hydraulic properties. This research aims to use the field test proposed by Velloso (2000), called Monitored Infiltration Test (EIM) to determine the Soil Water Characteristic Curve. In this test the constant head is maintained, using a constant head permeameter and, at the same time, monitoring a variation of the suction caused by the infiltration front with a tensiometer. When a variation of the suction in the soil becomes constant and close to zero, then, the test reached a condition of permanent flow, being possible to finalize the procedure. In addition, the soil water characteristic curve (SWCC) and the respective Van Genuchten parameters, that describes a saturation curve versus the matric potential, are obtained mathematically by solving the inverse problem. In this context, the main objective of this research is to develop a detailed evaluation of the numerical and experimental procedures to use it in the Monitored Infiltration Test (EIM), following the guidelines and recommendations pointed out in previous studies in the area. Moreover, was sought a better understanding of EIM, and for this, comparative analyzes were performed with laboratory test results of the filter paper type. In addition, it was added the soil moisture monitoring during the EIM. Finally, was used many optimization methods for parameter estimation. The tests developed and presented in this research, were performed in five areas around the State of Rio de Janeiro.

Resumo: Utilizando-se de dados hidrogeológicos em área selecionada na cidade de Londrina (PR), foi realizada avaliação da vulnerabilidade natural do aqüífero constituído pelo manto de alteração das rochas basálticas da Formação Serra Geral, através da aplicação do índice DRASTIC. Este método possui características de simplicidade, de baixo custo, de fácil aplicação e é amplamente utilizado em estudos de vulnerabilidade natural. A caracterização da susceptibilidade do meio à poluição fornece subsídios para tomada de decisões quanto ao uso e ocupação do solo e conseqüentemente ao planejamento sócio-econômico. Na zona não-saturada, através dos ensaios de infiltração, obteve-se baixa permeabilidade dos solos, com variações entre 10-3 cm/s e 10-5 cm/s. Os ensaios de slug, na zona saturada, por sua vez, indicaram condutividade hidráulica de 10-1 a 10-4 cm/s, apresentando média ao redor de 10-2 cm/s. Dessa forma, o poluente ao atingir a zona dos saprolitos, tende a se espalhar rapidamente através das linhas de fluxo subterrâneo. O fluxo preferencial subterrâneo apresenta-se orientado de sul para norte, seguindo grosso modo o declive do terreno. Em geral, na área de estudo predomina a vulnerabilidade moderada, enquanto que nas proximidades do ribeirão Lindóia e nos divisores d'água, as vulnerabilidades foram classificadas como alta e baixa, respectivamente.
Abstract: The DRASTIC index was used for the evaluation of the natural vulnerability of groundwater constituted by the mantle of weathering of the basaltic rocks of the Serra Geral Formation. DRASTIC method was used in this evaluation, for its simplicity, low cost, easy application and it has been widely used for analysis of the natural vulnerability. The characterization of the enviromental to the pollution supports the decisions about ground use and occupation for partner-economic planning. Hydraulic conductivities in the unsaturated and saturated zones, as well as the groundwater flow direction were determined. In the unsaturated zone, permeability of the soils is low, as reveled by infiltrations tests with ranging 10-3 cm/s to 10-5 cm/s. Hydraulic conductivity obtained from slug tests range from 10-1 to 10-4 cm/s, with average around 10-2 cm/s. The flow direction occurs from south to north, accompanying the general slope of the landscape. The pollutant when reaches the zone of the saprolite, tends to spread quickly through the groundwater flow lines. In general, the vulnerability of the studied area can be classified as moderate, while that in the water divide region and in the vicinity of ribeirão Lindóia, are ranked low and high, respectively.

Abstract:
Aluminium matrix composites are among the most promising candidate materials for light weight and high strength applications such as transportation and armour. In a previous study 6061 aluminum matrix composites reinforced with plain weave carbon fiber preform (AS4 Hexcel) were successfully fabricated by squeeze casting using the laminate fabrication technique. This research aims at optimizing the fabrication process in order to achieve improved strength and mechanical properties. It focuses on the liquid infiltration squeeze casting method. Good mechanical bonding between fiber and aluminium is achieved thanks to improved infiltration and impregnation of the fabric by liquid aluminium. Oxidation products at fiber/aluminium interface and porosity are reduced. As a result, composites are produced with overall improved mechanical properties. The flexural strength is increased by up to 19.9% and 15.4% compared to the laminate approach and the reference 6061 aluminium alloy squeeze cast under identical conditions, respectively. Similarly, overall hardness is improved. However, the impact strength is reduced by 7.76% and 25.78% when compared to casts fabricated by the laminate method and the reference aluminium alloy, respectively. The thesis constitutes a good basis for further research on fiber and particle reinforced aluminium matrix composites with the goal of further improving fracture toughness, particularly for gradient materials used in armour applications.

Full text
Abstract:
This thesis examines the hydrology of three experimental waste rock piles located in the Canadian Arctic at Diavik Diamond Mine (DDMI). Seven years of hydrology data is presented, including measurements of moisture contents, outflow volumes and soil tensions, along with an estimate of annual rainfall infiltration. The hydrology of each pile is influenced by freezing and thawing, and pore water flow is restricted to the time periods when the pile is thawed. The base of each pile contains drain pipes used to collect pore water from the piles, and these pipes are lined with internal heat traces. This research shows that the heat traces significantly influence the thermal behaviour and hydrology of the waste rock. A flooding event in the winter of 2012 interrupted power to the heat trace in two of the waste rock piles, and led to altered outflow volumes and patterns in 2013. A heat trace in the base of the third pile was intentionally turned off in 2011, and led to a significant decrease in the volume of outflow collected from the pile in 2012 and 2013. A bromide tracer was applied to the crest of one of the piles in 2007, and the recovery of the tracer is analysed until 2013. The results of this analysis are used to quantify the average residence time and flow velocity of pore water within the pile. The concentration of stable isotopes is analysed in outflow from the same pile, and is used to estimate the contribution of snowmelt to the total recharge received by the pile. The infiltration of snowmelt into another waste rock pile is estimated using the results of four snow surveys, a snowmelt ablation model, and an infiltration model suitable for use on frozen porous media. The research contained in this thesis provides information that will be incorporated into the final closure plan for DDMI, and will be used to help prevent the formation and release of low quality effluent from the full scale waste rock pile located at the mine site.

These buildings are naturally ventilated via air infiltration and airing. Air infiltration is the airflow through adventitious leakages in the building envelope, while airing is the intentional air exchange through large openings like windows and doors. Airing can in turn be performed either as single-sided (one opening) or as cross flow ventilation (two or more openings located on different walls). The total air exchange affects heating energy and indoor air quality. In churches, deposition of airborne particles causes gradual soiling of indoor surfaces, including paintings and other pieces of art. Significant amounts of particles are emitted from visitors and from candles, incense, etc. Temporary airing is likely to reduce this problem, and it can also be used to adjust the indoor temperature. The present study investigates mechanisms and prediction models regarding air infiltration and open-door airing by means of field measurements, experiments in wind tunnel and computer modelling. In natural ventilation, both air infiltration and airing share the same driving forces, i.e. wind and buoyancy (indoor-outdoor temperature differences). Both forces turn out to be difficult to predict, especially wind induced flows and the combination of buoyancy and wind. In the first part of the present study, two of the most established models for predicting air infiltration rate in buildings were evaluated against measurements in three historical stone churches in Sweden. A correction factor of 0.8 is introduced to adjust one of the studied models (which yielded better predictions) for fitting the large single zones like churches. Based on field investigation and IR-thermography inspections, a detailed numerical model was developed for prediction of air infiltration, where input data included assessed level of the neutral pressure level (NPL). The model functionality was validated against measurements in one of the case studies, indicating reasonable prediction capability. It is suggested that this model is further developed by including a more systematic calibration system for more building types and with different weather conditions. Regarding airing, both single-sided and cross flow rates through the porches of various church buildings were measured with tracer gas method, as well as through direct measurements of the air velocity in a porch opening. Measurement results were compared with predictions attained from four previously developed models for single‑sided ventilation. Models that include terms for wind turbulence were found to yield somewhat better predictions. According to the performed measurements, the magnitude of one hour single-sided open-door airing in a church typically yields around 50% air exchange, indicating that this is a workable ventilation method, also for such large building volumes. A practical kind of diagram to facilitate estimation of suitable airing period is presented. The ability of the IDA Indoor Climate and Energy (IDA-ICE) computer program to predict airing rates was examined by comparing with field measurements in a church. The programs’ predictions of single-sided airflows through an open door of the church were of the same magnitude as the measured ones; however, the effect of wind direction was not well captured by the program, indicating a development potential. Finally, wind driven air flows through porch type openings of a church model were studied in a wind tunnel, where the airing rates were measured by tracer gas. At single-sided airing, a higher flow rate was observed at higher wind turbulence and when the opening was on the windward side of the building, in agreement with field measurements. Further, the airing rate was on the order of 15 times higher at cross flow than at single-sided airing. Realization of cross flow thus seems highly recommendable for enhanced airing. Calibration constants for a simple equation for wind driven flow through porches are presented. The measurements also indicate that advection through turbulence is a more important airing mechanism than pumping.   The present work adds knowledge particularly to the issues of air infiltration and airing through doors, in large single zones. The results can be applicable also to other kinds of large single-zone buildings, like industry halls, atriums and sports halls.
Naturlig ventilation är den dominerande ventilationsprocessen i äldre byggnader såsom kyrkor, och även i de flesta småhus i Sverige och övriga delar av världen. Luftinfiltration och vädring utgör viktiga komponenter i naturlig ventilation, där luftinfiltration är luftflöde genom oavsiktliga läckage i byggnadsskalet, medan vädring är avsiktligt luftutbyte genom stora öppningar såsom fönster och dörrar/portar. Vädring kan i sin tur ske ensidigt (genom en öppning) eller som tvärdrag (genom två eller flera öppningar belägna på olika ytterväggar). Det totala luftutbytet påverkar värmeförluster och inomhusluftens kvalité. I kyrkor orsakar avsättning av luftpartiklar en gradvis nedsmutsning av invändiga ytor, inklusive väggmålningar och andra konstföremål. Betydande mängder partiklar avges från besökare, tända ljus, rökelse, o.d. Tillfällig vädring kan minska detta problem, men även användas för att justera innetemperaturen. Föreliggande studie analyserar mekanismer och predikteringsmodeller gällande luftinfiltration och dörrvädring genom fältmätningar, vindtunnelförsök och datorsimuleringar. Luftinfiltration och vädring har samma drivkrafter, d.v.s. vind och termik (inne‑ute temperaturskillnader). Båda dessa drivkrafter är svåra att predicera, särskilt vindinducerade flöden och kombinationen av termik och vind. Två av de mest etablerade modellerna för luftinfiltrationsprediktering i byggnader har utvärderats via mätningar i tre kulturhistoriska stenkyrkor i Sverige. En korrigeringsfaktor av 0,8 föreslås för bättre prediktion av den ena modellen (som gav bäst resultat) gällande höga en-zonsbyggnader såsom kyrkor. En detaljerad numerisk modell är utvecklad för luftinfiltrationsprediktering, där indata baseras på fältundersökningar, inkl. IR-termografering och uppmätt av neutrala tryckplanet (NPL). Modellens funktionalitet har validerats via mätningar i en av fallstudierna och pekar på tämligen god prediktionsprestanda. Vidare utveckling av modellen föreslås, inkl. ett mer systematiskt kalibreringssystem, för olika typer av byggnader och väderförhållanden. Gällande vädring mättes både ensidigt flöde och tvärdrag genom portar i olika kyrkobyggnader med hjälp av spårgas samt direkta lufthastighetsmätningar i portöppning. Mätresultaten jämfördes med erhållna prediktioner från fyra tidigare utvecklade modeller för ensidig ventilation. De modeller som tog hänsyn till vindturbulens gav något bättre resultat. Enligt utförda mätningar medför en timmes ensidig portvädring i en kyrka cirka 50 % luftutbyte, vilket indikerar att detta är en tillämpbar ventilationsmetod, även för så pass stora byggnadsvolymer. Ett särskilt vädringsdiagram presenteras, som syftar till att underlätta uppskattning av erforderlig vädringsperiod. Vidare studerades predikteringsprestanda hos IDA Indoor Climate and Energy (IDA-ICE) simuleringsprogram avseende vädring, där simuleringsdata jämfördes med fältmätningar i en kyrka. Programmets prediktion av ensidigt luftflöde genom en öppen kyrkport var av samma storlekordning som det uppmäta; dock klarade programmet inte av att hantera inverkan av vindriktning så väl, vilket pekar på en utvecklingspotential. Avslutningsvis undersöktes vinddrivet flöde igenom portöppningar i en kyrkmodell i vindtunnel, där luftomsättningen mättes med hjälp av spårgasmetoden. Vid ensidig vädring observerades högre flöde vid högre vindturbulens och när öppningen var på vindsidan av byggnaden, i överensstämmelse med fältmätningarna. Dessutom var vädringsflödet vid tvärdrag i storleksordningen 15 högre än det vid ensidig vädring. Det verkar alltså som att man kan öka vädringstakten avsevärt om man kan åstadkomma tvärdrag. Kalibreringskonstanter presenteras också för en enkel ekvation för vinddrivet flöde genom portar. Vindtunnelstudien indikerar vidare att advektion genom turbulens är en viktigare vädringsmekanism än pumpning. Föreliggande arbete bidrar med kunskap speciellt kring luftinfiltration och vädring genom portar i höga en-zonsbyggnader. Resultaten kan även vara tillämpliga på andra typer av höga en-zonsbyggnader såsom industrihallar, atrier/ljusgårdar och idrottshallar.

Abstract:
Thermal barrier coatings (TBC) are used in the hot sections of gas turbine engine in order to insulate the substrate at high temperature. Molten salt infiltration retards the durability of TBCs. The current standard material, i.e. 8YSZ is susceptible to molten salt infiltration. Therefore, alternate TBC materials are desirable. In addition to material composition, the TBC microstructure plays an important role in mitigating molten salt infiltration. Therefore, in this work, three different TBC variations were investigated. The first variation was a columnar microstructured 48YSZ TBC processed by SPS (48YSZ-SPS). The second variation was a columnar microstructured 8YSZ TBC processed by SPS (8YSZ-SPS), and the third variation was a lamellar microstructured 8YSZ TBC deposited by APS (8YSZ-APS). The as-sprayed TBC specimens were characterized by SEM/EDS, porosity analysis and XRD measurements. Later, the TBC specimens were exposed to hot corrosion test and their interaction with the molten salts were investigated using SEM (EDS and XRD). It was shown that an increase in stabilizer content (yttria content) in zirconia (in the case of 48YSZ) leads to an improved hot corrosion resistance due to the adequate amount of yttria content, which restricts the molten salt infiltration by forming needle like YVO4 phase. In terms of microstructure comparison, the infiltration behavior was similar for columnar microstructured 8YSZ and lamellar microstructured 8YSZ-APS as the molten salts infiltrated the coatings completely compared to the 48YSZ TBC. Furthermore, it seems that the molten salt infiltrates the TBC through globular pores, delamination cracks and splat boundaries in the case of APS-TBCs whereas the column gaps favor easier infiltration of molten salts in the case of columnar microstructured SPS processed TBCs.

Abstract:
This chapter explores the acoustical dynamics of the novels Sanctuary and As I Lay Dying (with an extended glance at Light in August) to demonstrate how intimately attuned Faulkner’s verbal art was at the turn of the decade (circa 1930) to new audio technologies, particularly the phonograph and radio. It shows how new recording, playback, and broadcasting media radically affected the literary category of “voice” in Faulkner’s novels, multiplying its sources, modifying its tense and person, and warping the very nature of its authority. The chapter asks how this subtle but irresistible infiltration of the novelistic domain of voice by new sound media might have provoked new kinds of aesthetic responsiveness at a higher, organizational level too (as regards the prevailing agon between romance and modernism), and so pulled the Faulknerian text in directions that opened it to unprecedented formal mutations.

Abstract:
One of the main features of Sjögren’s syndrome (SS) is the lymphocytic infiltration of the exocrine glands, mainly of the salivary and lacrimal glands, causing gland destruction. The severity of the salivary gland dysfunction is frequently associated with disease progression. Therefore, accurate assessment of salivary flow rates has diagnostic and prognostic value. However, in addition to the serological markers, the confirmative diagnostic test for SS at present is the assessment of lymphocytic infiltrate in a minor salivary gland biopsy. As the latter is an invasive and expensive procedure, there have been studies recently advocating the benefits of salivary gland ultrasound and other noninvasive tests in diagnosing SS and in eliminating or reducing the need for a biopsy.

Abstract:
The NASA High Speed Research (HSR)/Enabling Propulsion Materials (EPM) program was charged with the responsibility for developing the materials and technologies necessary to meet the High Speed Civil Transport (HSCT) engine requirements. The combustor liner was identified as a critical component for meeting the efficiency and environmental acceptability goals of the HSCT engine. The EPM Ceramic Matrix Composite (CMC) Combustor liner program was tasked with developing and demonstrating a material system and design concept that meets the HSCT environmental, thermal, structural, economic, and durability requirements. Melt Infiltration (MI) SiC/SiC composites were ultimately selected for the combustor liner application. The culmination of this development effort was the delivery and testing of a CMC combustor liner. Testing was performed at NASA Glenn Research Center in the Sector Rig under HSCT operating conditions. The initial results of the rig testing are presented.

Full text
Abstract:
Tracer gas and blower door testing are two widely used methods to determine the rate of air infiltration through a building envelope. Blower door testing is performed at elevated pressure differentials across the building envelope whereas tracer gas testing is conducted at near zero differential pressures, better reflecting the air leakage rate at near normal building operating conditions. The primary objective of this study was to determine whether extrapolation of blower door test data to normal building operating conditions provides a good estimate of annual average air infiltration at those conditions. Two methods were used to extrapolate the data and were then compared to the baseline tracer gas tests. A secondary objective was to determine the ventilation rate of a residential facility using tracer gas tests. Tracer gas testing seems to be more reliable in determining the air leakage rate at normal operating pressures, but is sensitive to the tracer gas and ambient weather conditions. Regardless, for the subject facility, the ACH50/20 rule and Sherman’s ACH50/N correlation, extrapolated from the blower door tests, are within 6%–33% and 4%–38% of the tracer gas results, respectively. However, these errors are dependent on the assumptions used. Nevertheless, it appears that simple blower door testing can provide a reasonable measure of a building’s annual average air infiltration rate regardless of ambient conditions, whereas the more expensive and complex tracer gas tests may better reflect seasonal variations in air infiltration rates.

Abstract:
The performance of yttria stabilized zirconia (YSZ), ceria stabilized zirconia (CSZ), and magnesia stabilized zirconia (MSZ) coatings was evaluated using an atmospheric burner rig; the test environment contained compounds of vanadium, sodium and sulfur. The coatings were deposited by plasma spraying and electron beam physical vapor deposition (EB-PVD); sputtered sealant layers of hafnia, alumina and platinum were deposited on the yttria stabilized zirconia coating (YSZ). The tests were performed for up to 500 hours at 1650°F and 1300°F. The tests were designed to simulate the deposit chemistry and sulfur trioxide partial pressures expected in a marine gas turbine engine operating on contaminated fuel. YSZ, CSZ, and MSZ coatings all underwent reaction in the burner rig environment; the reaction products and their effects on spallation were varied. MSZ was by far the most reactive, readily forming MgSO4 in both 1650°F and 1300°F tests. The observed reaction products provided a measure of “protection” for the bond coat by preventing molten salt infiltration in the duration of the test. The mechanism of ceramic spallation is discussed. Sputtered overlayers of platinum, hafnia and alumina did not prevent salt infiltration and reaction with the underlying ceramic, although no reaction product between the overlayer and the salt was observed.

Abstract:
A 12′ by 24′ passive solar test building has been constructed on the campus of the University of Louisville. The building envelope is comprised of structural insulated panels (SIPs), 12″ thick, (R-value of 45 ft2F/Btu) for the floor and walls and 16″ (R-63) for the roof. The building is divided into two symmetrical rooms with a 12″ SIPs wall separating the rooms. All joints between panels are caulked to reduce infiltration. Each room contains one window (R-9) on the north side wall, and two windows (also R-9) facing south for ventilation and daylighting, but which will also provide some direct gain heating. The south wall of each room features an opening that will accommodate a passive solar heating system so that performance of two systems can be compared side-by-side. The overhang above the south openings is purposely left short to accommodate an awning to provide adjustable shading. The calculated loss coefficient (UA) for each room of the building is 6.07 W/K. Each room is also equipped with a data acquisition system consisting on an SCXI 1600 16 bit digitizer and an SCXI 1102B isolation amplifier with an SCXI 1303 thermocouple module. Pyranometers are placed on the south wall and the clerestory wall to measure insolation on the solar apertures. For initial tests, one room is equipped with an original heat pipe system previously tested in another building, while the other is equipped with a modified heat pipe system. Changes to the modified system include copper absorbers versus aluminum, an adiabatic section constructed of considerably less thermally-conductive DPM rubber than the copper used for the original design, and one of the five condenser sections of the heat pipes is exposed directly to the room air to provide early-morning heating. Experimental results will be compared to simulations with as-built building characteristics and actual weather data. Previous simulations with a load to collector ratio of 10 W/m2K, a defined room comfort temperature range between 65°F to 75°F, and TMY3 weather data for Louisville, KY, showed that the modified heat pipe wall design improves annual solar fraction by 16% relative to the original design.

Abstract:
Soil water wettability or water repellency is a phenomenon that can affect infiltration and, ultimately, runoff. Thus, there is a need to develop a model that can quantitatively capture the influence of water repellency on infiltration in a physically meaningful way and within the framework of existing infiltration theory. The analytical model developed in this study relates soil sorptivity (an infiltration parameter) with contact angle (a direct measure of water repellency) for variably saturated media. The model was validated with laboratory experiments using a silica sand of known properties treated to produce controlled degrees of water repellency. The measured contact angle and sorptivity values closely matched the model‐predicted values. Further, the relationship between the frequently used water drop penetration time test (used to assess water repellency) and sorptivity was illustrated. Finally, the direct impact of water repellency on saturated hydraulic conductivity was investigated due to its role in infiltration equations and to shed light on inconsistent field observations. It was found that water repellency had minimal effect on the saturated hydraulic conductivity of structureless sand. A quantitative model for infiltration incorporating the effect of water repellency is particularly important for post‐fire hydrologic modeling of burned areas exhibiting water repellent soils.
