Abstract:
ABSTRACT We found 73.1 to 96.9% similarity by aligning the cytolytic enterotoxin gene of Aeromonas hydrophila SSU (AHCYTOEN; GenBank accession no. M84709 ) against aerolysin genes ofAeromonas spp., suggesting the possibility of selecting common primers. Identities of 90 to 100% were found among the eight selected primers from those genes. Amplicons obtained fromAeromonas sp. reference strains by using specific primers for each gene or a cocktail of primers were 232 bp long. Of hybridization group 4/5A/5B (HG4/5A/5B), HG9, and HG12 or non-Aeromonas reference strains, none were positive. PCR-restriction fragment length polymorphism (PCR-RFLP) withHpaII yielded three types of patterns. PCR-RFLP 1 contained two fragments (66 and 166 bp) found in HG6, HG7, HG8, HG10, and HG11. PCR-RFLP 2 contained three fragments (18, 66, and 148 bp) found in HG1, HG2, HG3, and HG11. PCR-RFLP 3, with four fragments (7, 20, 66, and 139 bp), was observed only in HG13. PCR-amplicon sequence analysis (PCR-ASA) revealed three main types. PCR-ASA 1 had 76 to 78% homology with AHCYTOEN and included strains in HG6, HG7, HG8, HG10, and HG11. PCR-ASA 2, with 82% homology, was found only in HG13. PCR-ASA 3, with 91 to 99% homology, contained the strains in HG1, HG2, HG3, and HG11. This method indicated that 37 (61%) of the 61 reference strains were positive with the primer cocktail master mixture, and 34 (58%) of 59 environmental isolates, 93 (66%) of 141 food isolates, and 100 (67%) of 150 clinical isolates from around the world carried a virulence factor when primers AHCF1 and AHCR1 were used. In conclusion, this PCR-based method is rapid, sensitive, and specific for the detection of virulence factors of Aeromonas spp. It overcomes the handicap of time-consuming biochemical and other DNA-based methods.

Abstract:
Abstract. L. Zhang et al. (2012), in a recent report, compared model estimates with new observations of oxidized and particulate mercury species (Hg2+ and Hgp) in the Great Lakes region and found that the sum of Hg2+ and Hgp varied between a factor of 2 to 10 between measurements and model. They suggested too high emission inputs as Hg2+ and too fast oxidative conversion of Hg0 to Hg2+ and Hgp as possible causes. This study quantitatively explores measurement uncertainties in detail. These include sampling efficiency, composition of sample, interfering species and calibration errors. Model (Global/Regional Atmospheric Heavy Metals Model – GRAHM) sensitivity experiments are used to examine the consistency between various Hg measurements and speciation of Hg near emission sources to better understand the discrepancies between modelled and measured concentrations of Hg2+ and Hgp. We find that the ratio of Hg0, Hg2+ and Hgp in the emission inventories, measurements of surface air concentrations of oxidized Hg and measurements of wet deposition are currently inconsistent with each other in the vicinity of emission sources. Current speciation of Hg emissions suggests higher concentrations of Hg2+ in air and in precipitation near emission sources; however, measured air concentrations of Hg2+ and measured concentrations of Hg in precipitation are not found to be significantly elevated near emission sources compared to the remote regions. The averaged unbiased root mean square error (RMSE) between simulated and observed concentrations of Hg2+ is found to be reduced by 42% and for Hgp reduced by 40% for 21 North American sites investigated, when a ratio for Hg0 : Hg2+ : Hgp in the emissions is changed from 50 : 40 : 10 (as specified in the original inventories) to 90 : 8 : 2. Unbiased RMSE reductions near emissions sources in the eastern United States and Canada are found to be reduced by up to 58% for Hg2+. Significant improvement in the model simulated spatial distribution of wet deposition of mercury in North America is noticed with the modified Hg emission speciation. Measurement-related uncertainties leading to lower estimation of Hg2+ concentrations are 86%. Uncertainties yielding either to higher or lower Hg2+ concentrations are found to be 36%. Finally, anthropogenic emission uncertainties are 106% for Hg2+. Thus it appears that the identified uncertainties for model estimates related to mercury speciation near sources, uncertainties in measurement methodology and uncertainties in emissions can close the gap between modelled and observed estimates of oxidized mercury found in L. Zhang et al. (2012). Model sensitivity simulations show that the measured concentrations of oxidized mercury, in general, are too low to be consistent with measured wet deposition fluxes in North America. Better emission inventories (with respect to speciation), better techniques for measurements of oxidized species and knowledge of mercury reduction reactions in different environments (including in-plume) in all phases are needed for improving the mercury models.

Abstract. Zhang et al. (2012a), in a recent report, compared model estimates and new observations of oxidised and particulate mercury species (Hg2+ and Hgp) in the Great Lakes region and found that the sum of Hg2+ and Hgp varied between a factor of 2 to 10 between measurements and model. They suggested too high emission inputs and too fast oxidative conversion of Hg0 to Hg2+ and Hgp, as possible causes. This study quantitatively explores in detail the uncertainties in measurements, in addition to the above concerns and speciation of mercury near emission sources in the model to better understand these discrepancies in the context of oxidized mercury, i.e. gaseous (Hg2+) and particulate (Hgp) mercury. These include sampling efficiency, composition of sample, interfering species and calibration errors for measurements and in-plume reduction processes. Sensitivity simulations using Global/Regional Atmospheric Heavy Metals Model (GRAHM) were performed to analyze the role of in-plume reduction on ambient concentrations and deposition of mercury in North America. The discrepancy between simulated and observed concentrations of Hg2+ and Hgp was found to be reduced when a ratio for Hg0:Hg2+:Hgp in the emissions was changed from 50:40:10 (as specified in the original inventories) to 90:8:2 to account for in-plume reduction of Hg0 processes. A significant reduction of the root mean square error (e.g., 19.22 to 11.3 pg m−3 for New Jersey site NJ54) and bias (67.8 to 19.3 pg m−3 for NJ54) for sampling sites in the Eastern United States and Canada, especially for sites near emission sources was found. Significant improvements in the spatial distribution of wet deposition of mercury in North America was noticed. Particularly, over-prediction of wet deposition near anthropogenic sources of mercury was reduced by 43%. On a regional scale, estimated wet deposition improved by a factor of 2 for areas with more than 12 μg m−2 yearly average wet deposition. Model sensitivity simulations show that the measured concentration of oxidized mercury is too low to be consistent with measured wet deposition fluxes in North America. This improvement by a factor of 2 and measurement uncertainties within a factor of 3 to 8 provides a reasonable rationale for the discrepancy of a factor of 2–10 determined by Zhang et al. (2012a).

Abstract:
Abstract. Mercury transformation mechanisms and speciation profiles are reviewed for mercury formed in and released from flue gases of coal-fired boilers, non-ferrous metal smelters, cement plants, iron and steel plants, waste incinerators, biomass burning and so on. Mercury in coal, ores, and other raw materials is released to flue gases in the form of Hg0 during combustion or smelting in boilers, kilns or furnaces. Decreasing temperature from over 800 °C to below 300 °C in flue gases leaving boilers, kilns or furnaces promotes homogeneous and heterogeneous oxidation of Hg0 to gaseous divalent mercury (Hg2+), with a portion of Hg2+ adsorbed onto fly ash to form particulate-bound mercury (Hgp). Halogen is the primary oxidizer for Hg0 in flue gases, and active components (e.g., TiO2, Fe2O3, etc.) on fly ash promote heterogeneous oxidation and adsorption processes. In addition to mercury removal, mercury transformation also occurs when passing through air pollution control devices (APCDs), affecting the mercury speciation in flue gases. In coal-fired power plants, selective catalytic reduction (SCR) system promotes mercury oxidation by 34–85 %, electrostatic precipitator (ESP) and fabric filter (FF) remove over 99 % of Hgp, and wet flue gas desulfurization system (WFGD) captures 60–95 % of Hg2+. In non-ferrous metal smelters, most Hg0 is converted to Hg2+ and removed in acid plants (APs). For cement clinker production, mercury cycling and operational conditions promote heterogeneous mercury oxidation and adsorption. The mercury speciation profiles in flue gases emitted to the atmosphere are determined by transformation mechanisms and mercury removal efficiencies by various APCDs. For all the sectors reviewed in this study, Hgp accounts for less than 5 % in flue gases. In China, mercury emission has a higher Hg0 fraction (66–82 % of total mercury) in flue gases from coal combustion, in contrast to a greater Hg2+ fraction (29–90 %) from non-ferrous metal smelting, cement and iron and/or steel production. The higher Hg2+ fractions shown here than previous estimates may imply stronger local environmental impacts than previously thought, caused by mercury emissions in East Asia. Future research should focus on determining mercury speciation in flue gases from iron and steel plants, waste incineration and biomass burning, and on elucidating the mechanisms of mercury oxidation and adsorption in flue gases.

Abstract. Long-term continuous measurements of gaseous elemental mercury (Hg0), reactive gaseous mercury (RGM), and particulate phase mercury (HgP) were conducted at coastal (Thompson Farm, denoted as TF), marine (Appledore Island, denoted as AI), and elevated inland rural (Pac Monadnock, denoted as PM) monitoring sites of the AIRMAP Observing Network. Diurnal, seasonal, annual, and interannual variability in Hg0, RGM, and HgP from the three distinctly different environments were characterized and compared in Part 1. Here in Part 2 relationships between speciated mercury (i.e., Hg0, RGM, and HgP) and climate variables (e.g., temperature, wind speed, humidity, solar radiation, and precipitation) were examined. The best point-to-point correlations were found between Hg0 and temperature in summer at TF and spring at PM, but there was no similar correlation at AI. Subsets of data demonstrated regional impacts of episodic dynamic processes such as strong cyclonic systems on ambient levels of Hg0 at all three sites, possibly through enhanced oceanic evasion of Hg0. A tendency of higher levels of RGM and HgP was identified in spring and summer under sunny conditions in all environments. Specifically, the 10th, 25th, median, 75th, and 90th percentile mixing ratios of RGM and HgP increased with stronger solar radiation at both the coastal and marine sites. These metrics decreased with increasing wind speed at AI indicating enhanced loss of RGM and HgP through deposition. RGM and HgP levels correlated with temperature positively in spring, summer and fall at the coastal and marine locations. At the coastal site relationships between RGM and relative humidity suggested a clear decreasing tendency in all metrics from <40% to 100% relative humidity in all seasons especially in spring, compared to less variability in the marine environment. The effect of precipitation on RGM at coastal and marine locations was similar. At the coastal site, RGM levels were a factor of 3–4 to two orders of magnitude higher under dry conditions than rainy conditions in all seasons. In winter RGM mixing ratios appeared to be mostly above the limit of detection (LOD) during snowfalls suggesting less scavenging efficiency of snow. Mixing ratios of HgP at the coastal and marine sites remained above the LOD under rainy conditions. Precipitation had negligible impact on the magnitude and pattern of diurnal variation of HgP in all seasons in the marine environment.

Abstract. Mercury transformation mechanisms and speciation profiles are reviewed for mercury formed in and released from flue gases of coal-fired boilers, non-ferrous metal smelters, cement plants, iron and steel plants, municipal solid waste incinerators, and biomass burning.

The coal-fired power plant is the main anthropogenic source of mercury pollution. The mercury in flue gas exists as elemental mercury(Hg0), oxidizing state mercury(Hg2+) and particulate mercury(Hgp). Mercury speciation distribution in flue gas was influenced and controled by the factors including conditions of ignition, desulphurization or denitration and Based on the investigation of coal-fired power plant technologies of removing Hg, this research uses the modified activated carbon (MAC) and studies its removal efficiency. Result indicates that the uptake of Hg by MAC was﹥90%.

Abstract:
The introduction of a hybrid genetic programming method (hGP) in fitting and forecasting of the broadband penetration data is proposed. The hGP uses some well-known diffusion models, such as those of Gompertz, Logistic, and Bass, in the initial population of the solutions in order to accelerate the algorithm. The produced solutions models of the hGP are used in fitting and forecasting the adoption of broadband penetration. We investigate the fitting performance of the hGP, and we use the hGP to forecast the broadband penetration in OECD (Organisation for Economic Co-operation and Development) countries. The results of the optimized diffusion models are compared to those of the hGP-generated models. The comparison indicates that the hGP manages to generate solutions with high-performance statistical indicators. The hGP cooperates with the existing diffusion models, thus allowing multiple approaches to forecasting. The modified algorithm is implemented in the Python programming language, which is fast in execution time, compact, and user friendly.

Abstract:
Abstract. Mercury (Hg) emissions from biomass burning (BB) are an important source of atmospheric Hg and a major factor driving the interannual variation of Hg concentrations in the troposphere. The greatest fraction of Hg from BB is released in the form of elemental Hg (Hg0(g)). However, little is known about the fraction of Hg bound to particulate matter (HgP) released from BB, and the factors controlling this fraction are also uncertain. In light of the aims of the Minamata Convention to reduce intentional Hg use and emissions from anthropogenic activities, the relative importance of Hg emissions from BB will have an increasing impact on Hg deposition fluxes. Hg speciation is one of the most important factors determining the redistribution of Hg in the atmosphere and the geographical distribution of Hg deposition. Using the latest version of the Global Fire Emissions Database (GFEDv4.1s) and the global Hg chemistry transport model, ECHMERIT, the impact of Hg speciation in BB emissions, and the factors which influence speciation, on Hg deposition have been investigated for the year 2013. The role of other uncertainties related to physical and chemical atmospheric processes involving Hg and the influence of model parametrisations were also investigated, since their interactions with Hg speciation are complex. The comparison with atmospheric HgP concentrations observed at two remote sites, Amsterdam Island (AMD) and Manaus (MAN), in the Amazon showed a significant improvement when considering a fraction of HgP from BB. The set of sensitivity runs also showed how the quantity and geographical distribution of HgP emitted from BB has a limited impact on a global scale, although the inclusion of increasing fractions HgP does limit Hg0(g) availability to the global atmospheric pool. This reduces the fraction of Hg from BB which deposits to the world's oceans from 71 to 62 %. The impact locally is, however, significant on northern boreal and tropical forests, where fires are frequent, uncontrolled and lead to notable Hg inputs to local ecosystems. In the light of ongoing climatic changes this effect could be potentially be exacerbated in the future.

Abstract:
Os objetivos dos experimentos foram primeiro determinar as taxas de desenvolvimento in vitro de embriões murinos no estágio de 8-células expostos a 15.7 MPa de N2 durante 2 ou 4 horas. Segundo, determinar as taxas de sobrevivência embrionária à crioconservação dos blastocistos originados a partir do cultivo dos embriões de 8-células após a indução do estresse subletal celular com o auxílio da pressão gasosa. Terceiro, determinar a expressão dos genes BAX, Bcl2, GLUT1, GLUT3, IGF1, IGF2, IGF1-R, IGF2-R, SOD2, HSP70.1, AQP3 e PPIA nas seguintes etapas experimentais: no estágio de 8-células imediatamente após a coleta dos embriões; no estágio de blastocisto antes e após o congelamento. Nas seis replicações realizadas foram utilizados 14 machos e 60 fêmeas Mus musculus domesticus. Na primeira etapa dos experimentos, das fêmeas superovuladas, 38 produziram 1092 embriões viáveis no estágio de 8-células que foram, de forma aleatória, divididos em quatro grupos experimentais: Grupo P1 – os embriões foram expostos a 15.7 MPa de N2 gasoso durante 2 horas e após cultivados in vitro até alcançar o estádio de blastocisto; Grupo P2 – os embriões foram tratados de maneira idêntica aos do Grupo P1, sendo expostos aos 15.7 MPa de N2 gasoso durante 4 horas; Grupo controle CE - os embriões foram submetidos ao cultivo in vitro imediatamente após a coleta; Grupo controle CB: os embriões foram mantidos em temperatura ambiente (22 ºC) durante 4 horas e após colocados na estufa para o cultivo in vitro. Na segunda etapa, amostras dos embriões dos quatro grupos experimentais tiveram a expressão gênica determinada com auxílio da amplificação e determinação quantitativa do mRNA (“Real Time PCR”). Os resultados do desenvolvimento embrionário ao estágio de blastocisto na primeira etapa foram os seguintes: Grupo P1 – 96,4% (245/253); Grupo P2 – 94,0% (253/269); Grupo CE – 95,0% (249/262) e Grupo CB – 95,4 (249/261). Na segunda etapa dos experimentos os resultados de reexpansão dos blastocistos após a criopreservação foram: Grupo P1 – 86,3% (63/73); Grupo P2 – 80,0 (76/95); Grupo CE – 72,8 (67/92); Grupo CB – 83,6 (92/110). A análise da expressão da maioria dos genes não revelou diferenças entre os grupos experimentais, provavelmente devido à variação biológica dos embriões entre os grupos e dentro de um mesmo grupo. A exposição dos embriões no estágio de 8-células a 15.7 MPa de N2 gasoso não comprometeu a viabilidade in vitro para desenvolverem-se ao estágio de blastocisto. As taxas de sobrevivência dos blastocistos à criopreservação diferiram somente entre os grupos de embriões expostos à HGP durante 2 horas (P1) no estágio de 8-células (86,3%) e o grupo de embriões submetidos ao cultivo in vitro (CE) (72,8%). Os resultados dos experimentos revelaram que a HGP pode ser empregada na indução de estresse celular subletal em embriões murinos.
The first objective of the experiments was to determine the development rates of mouse embryos exposed to high gaseous pressure (HGP – 15.7 MPa gaseous N2) at 8-cell stage for 2 or 4 hours. Second, determine the blastocyst re-expansion rates after cryopreservation. Third, determine the relative expression of BAX, Bcl2, GLUT1, GLUT3, IGF1, IGF2, IGF1-R, IGF2-R, SOD2, HSP70.1, AQP3 and PPIA in the following experimental steps: immediately after collection of 8-cell stage embryos, at the blastocyst stage before and after freezing. Fourteen males and 60 females Mus musculus domesticus were used in six experiment replications. Thirty-eight (63%) from the 60 superovulated, females produced 1092 viable embryos. These 8-cell stage embryos were then randomly divided into four experimental groups: P1 group – embryos were first exposed to 15.7 MPa of gaseous N2 for 2 hours and after cultured in vitro until the blastocyst stage; P2 group - embryos were treated identically to the P1 group, but were exposed to 15.7 MPa of gaseous N2 for 4 hours; CE control group - embryos were submitted to in vitro culture immediately after collection; CB control group - embryos were maintained at room temperature (22ºC) for 4 hours and after cultured in vitro. The results of embryo in vitro development to the blastocyst stage were: P1 Group- 96.4% (245/253); P2 group- 94.0% (253/269); CE group- 95.0% (249/262) and CB- 95.4 (249/261). After cryopreservation the blastocyst re-expansion rates were: P1 group- 86.3 % (63/73); P2 group- 80.0 (76/95); CE group – 72.8 (67/92), CB group- 83.6 (92/110). No major differences in gene expression were observed among treatment groups for most genes analyzed in this study, likely due to the biological variability in groups of embryos within each group. Exposure of embryos at 8-cells stage to 15.7 MPa of gaseous N2 did not compromise in vitro embryo viability to reach the blastocyst stage. The survival rates of blastocysts to cryopreservation differ only among the embryos that were exposed to the HGP during 2 hours at 8-cell stage (86,3 %) and the 8-cell stage embryos that were submitted to the in vitro culture immediately after collection (72,8 %). The experimental results showed that HGP can be used to induce sublethal cell stress in murine embryos.

A presente pesquisa é um convite ao leitor a navegar no que foi vivido por mim, no papel de pesquisadora ao buscar o movimento cultural juvenil hip hop na Escola de Educação Básica Lucia do Livramento Mayvorne, no Morro do Monte Serrat em Florianópolis. Em todo processo investigativo procurei ter um olhar para este movimento cultural juvenil e para os adolescentes aqui chamados por: Margarida, Rosa, Violeta, Cravo, Dália, Jasmim, Girassol, Bromélia, Lírio e Cacto que trouxeram suas experiências desta cultura dando corpo à pesquisa. Entendi que os gestos, movimentos corporais e o estilo de seu vestuário vinham imbuídos da identidade negra, com suas tranças e seu gingado corporal. O conceito de identidade diz respeito ao pertencimento social, cultural, étnico e de gênero, pertencimento que se constrói na família, nos ambientes sociais e institucionais, por meio de comparações e contrastes nas inter-relações socioculturais. Vi em meu corpo e no prazer pela dança uma cumplicidade para a pesquisa. Compõem esta pesquisa as falas dos adolescentes, do professor de educação física, da professora de arte-educação e da diretora da escola, em relação ao corpo e dança que é o principal objeto deste estudo, onde busquei minhas reflexões, tendo como base o referencial-teórico metodológico dos estudos culturais. Na experiência da dança e do corpo os adolescentes mostraram sua importância fotografando as coreografias do movimento cultural juvenil hip hop. Fica, para a leitura do trabalho completo, a reflexão desta cultura na fala dos adolescentes negros/as pesquisados. The current research is an invitation to the reader to sail into what has been lived for me, as a researcher, reaching the hip-hop young cultural movement in the Lucia do Livramento Mayvorne´s elementary school, in the Monte Serrat hill in Florianópolis. Through the whole investigative process, I tried to have a look on this young cultural movement and on the adolescents here called: Daisy, Rose, Violet, Clove, Dahlia, jasmine, sunflower, Bromeliad, Lily and Cactus that brought their experiences of this culture giving substance to the Research. I understood that gestures, corporal motion and vestry style came imbued with the black identity, marked by their braid hairs and body swaying. The concept of identity says about the social, cultural, ethnic and gender belonging, which is constructed in family, social and institutional atmospheres, over comparisons and assays in the socio-cultural inter-relations. I have seen in my body and in the pleasure for dance complicity for the research. This research is composed by the discourse of the adolescents, physical education teachers, arts teacher and the school principal, in connection to the body and dance, which are the main object of this research, where I searched for my reflections, having the theoretical-methodological allusion of the cultural researches as support. On the dance and body experience, the adolescents manifested their importance by photographing the choreographies of the hip-hop young cultural movement. Stays for the reading of the complete research, the reflection of this culture on the discourse of black adolescents that were here investigated.

Esta dissertação discute questões em torno das convenções de gênero e feminismo no Hip Hop em Salvador a partir da perspectiva das jovens militantes. Busca-se analisar a possibilidade de um hip hop feminista soteropolitano, com vistas à compreensão do feminismo na sua pluralidade como movimento social. Para tanto, considera-se as formas de apropriação dos discursos feministas e o engajamento em suas bandeiras na militância das interlocutoras da pesquisa. Ressalta-se a atenção à articulação entre os marcadores sociais de gênero, sexualidade e raça na prática política investigada. Assumindo o método qualitativo de pesquisa, esta investigação de cunho etnográfico utilizou-se de entrevistas semiestruturadas realizadas junto às hip hoppers, bem como da observação participante oriunda da convivência junto ao grupo estudado, sob o aporte interdisciplinar dos estudos de gênero e feministas.

Abstract:
AbstractThe field of biotechnology has been rigorously researched and applied to many facets of everyday life. Biotechnology is defined as the process of modifying an organism or a biological system for an intended purpose. Biotechnology applications range from agricultural crop selection to pharmaceutical and genetic processes (Bauer and Gaskell 2002). The definition, however, is evolving with recent scientific advancements. Until World War II, biotechnology was primarily siloed in agricultural biology and chemical engineering. The results of this era included disease-resistant crops, pesticides, and other pest-controlling tools (Verma et al. 2011). After WWII, biotechnology began to shift domains when advanced research on human genetics and DNA started. In 1984, the Human Genome Project (HGP) was formerly proposed, which initiated the pursuit to decode the human genome by the private and academic sectors. The legacy of the project gave rise to ancillary advancements in data sharing and open-source software, and solidified the prominence of “big science;” solidifying capital-intensive large-scale private-public research initiatives that were once primarily under the purview of government-funded programs (Hood and Rowen 2013). After the HGP, the biotechnology industry boomed as a result of dramatic cost reduction to DNA sequencing processes. In 2019 the industry was globally estimated to be worth $449.06 billion and is projected to increase in value (Polaris 2020).

Abstract:
This paper introduces a generalization of the heuristic gradient projection (HGP) method for solving 2D and 3D frames. The main objective is to minimize the frame weight by means of size, topology and shape optimization considering stress constraint activation. HGP can give a specific iterative equation for each element cross section and loading type and consequently reach the optimum solution in a relatively smaller number of iterations compared to general heuristic recursive equations. However, the solution of frames with combined loads applied on the elements might converge slowly or oscillate around the constrained optimum value. Many approaches were investigated for the generalization of the HGP. However, the emphasis was always directed towards axial and bending loads. Although other types of loads may have an effect on the problem, like shear and torsion stresses in shafts or 3D frames. These types of loads are introduced into the optimization problem with more general algorithm. Weighting factors are utilized to give a weight to each stress type applied on each element. This factor is used to change the power of the HGP iterative formula for each element in the frame, which changes the power of the recursive formula according to the contribution of each loading type applied on the element. The proposed technique shows more accurate results in activating the stress constraints than previously developed HGP when dealing with combined loads, and keeps the advantage of the HGP in finding the optimum solution in a relatively small number of structural analyses. In the case studies several sample applications were solved to highlight the robustness of the proposed method.

Abstract:
Abstract This paper proposes a system reliability analysis method based on the hybrid of multivariate Gaussian process (MGP) and univariate Gaussian process (UGP) models, named as hybrid Gaussian process-based system reliability analysis (HGP-SRA). MGP and UGP models are selectively constructed for the components of a complex engineered system: MGP models are constructed over the groups of highly interdependent components and the individual UGP models are built over the components which are relatively independent of one another. A nonlinear-dependence measure, namely the randomized dependence coefficient, is adopted to adaptively learn and quantify the pairwise dependencies of the components with both linear and nonlinear dependency patterns. In the proposed HGP-SRA method, initial hybrid Gaussian process (HGP) models are first constructed with a set of near-random samples and these surrogate models are then updated with new samples that are sequentially identified based on the acquisition function named as multivariate probability of improvement (MPI). The results of two mathematical and a real-world engineering case studies suggest that the proposed method can achieve better accuracy and efficiency in system reliability estimation than the benchmark surrogate-based methods.

This paper presents research work about the design and optimization of pressure vessels using Hybrid Heuristic Gradient Projection (HGP), Sequential Quadratic Programming (SQP) and Genetic Algorithms (GA). The design is concerned with the pressure loading conditions, intended internal utility volume, geometrical dimensions and the induced stresses. Cylindrical pressure vessels with hemispherical ends are considered. They are required to hold a definite volume under a specific pressure. The thicknesses of each hemispherical part and the cylindrical part satisfy the recommended ASME code. The design also satisfies allowable stress constraints. The design multi-objectives are to generate the optimum geometry to satisfy required specifications, performance and cost requirements. A developed HGP, SQP and GA algorithms are utilized to perform the optimization. The efficiency of the procedure is indicated and the optimum results in the form of optimum design charts are presented.

Abstract:
This paper determines the influence of different defective components in the hot-gas path (HGP) of a civil aircraft engine on the density distribution in the exhaust. The intention is to automate the identification of defective components inside the HGP through an analysis of the density distribution in the exhaust jet. The defects include an increased radial gap of the blades in the high-pressure turbine (HPT), and a reduction of the film cooling air mass flow in the first stage of the HPT. In addition, several combinations of both defects are simulated. In the present paper the exhaust density distributions are generated numerically using CFD simulations of the HGP. The density distribution in the exhaust jet is reconstructed with synthetic Background-Oriented Schlieren (BOS) measurements and automatically analyzed. The methodology for the automated defect detection consists of two algorithms, a Support Vector Machine (SVM) algorithm to automatically classify each measurement into a corresponding defect or reference class and an outlier detection algorithm to detect variations from the reference state — without assignment. It is shown that BOS provides a sufficient reconstruction quality to automatically detect defective HGP components with a SVM algorithm. It is possible to automatically detect both defects, even when they occur at the same time. For this purpose, different features were calculated to isolate the influence of each defect on the density distribution. The outlier detection algorithm allows for an automated detection of variations in the density distribution compared to the reference state without any previous knowledge of the influence of the defects on the density distributions during the training procedure. With this algorithm it is possible to detect unknown or new defects which have not been observed or regarded yet. These results strengthen the hypothesis, that an automated detection of defects in jet engines prior to the disassembly is possible.

Abstract:
Modeling and unit-cost optimization of a water-heated humidification-dehumidification (HDH) desalination system were presented in previous work of the authors. The system controlled the saline water flow rate to prevent salts from precipitating at higher water temperatures. It was then realized that this scheme had a negative impact on condensation performance when the controlled flow rate was not sufficiently high. This work builds on the previous system by disconnecting the condenser from the saline water cycle and by introducing a solar air heater to further augment the humidification performance. In addition, improved models for the condenser and the humidifier were used to obtain more accurate productivity estimations. The Heuristic Gradient Projection (HGP) optimization procedure was also refactored to result in reduced number of function evaluations to reach the global optimum compared to Genetic Algorithms (GA’s). A case study which assumes a desalination plant on the Red Sea near the city of Hurghada is presented. The unit-cost of produced fresh water for the new optimum system is $0.5/m3 compared to $5.9/m3 for the HDH system from previous work and less than the reported minimum cost of reverse osmoses systems.

Abstract:
In this paper, a new methodology to obtain an optimal structure size considering geometries nonlinearity is presented. This method makes use of Heuristic Gradient Projection method in addition to Fuzzy Logic. The Heuristic Gradient Projection (HGP) method, a previously developed method for 3D-frame design and optimization, utilizes mainly bending stress relations in order to simplify the process of iterations. HGP is based on comparing the resulting equivalent stress with the allowable stress value. The proposed Fuzzy Heuristic Gradient Projection (FHGP) approach incorporates both bending stress and axial stress when processing with the allowable stress value. The weighting factors of both axial and bending stresses are found using a Fuzzy Logic controller. Fuzzy logic is incorporated to reach an optimal solution with lesser number of function evaluations. A simple cantilever example, subjected to axial force and bending moment, is presented to illustrate this approach in addition to a 10-member planar frame that is used to prove the efficacy of the new method. FHGP approach generally results in faster convergence.

Full text
Abstract:
Thermal barrier coatings (TBCs) are applied to blades, vanes, combustion chamber walls, and exhaust nozzles in gas turbines not only to limit the heat transfer through the coatings but also to protect the metallic parts from the harsh oxidizing and corrosive thermal environment. There is a growing interest in operating these hot gas path (HGP) components at optimal conditions which has resulted in a continuous increase of the turbine inlet temperatures (TITs). This has resulted in the increase of heat load on the turbine components especially in the high pressure side of the turbine necessitating the need to protect the HGP components from the heat of the exhaust gases using novel TBC such as electron beam physical vapor deposition thermal barrier coatings (EBPVD TBCs) and Air Plasma Sprayed thermal barrier coatings (APS TBCs). This study focuses on the estimation of temperature distribution in the turbine metal substrate (IN738) and coating materials (EBPVD TBC and APS TBC) subjected to isothermal conditions (1573 K) around the turbine blade. The heat conduction in the turbine blade and TBC systems necessary for the evaluation of substrate thermal loads are assessed. The steady state 2D heat diffusion in the turbine blade is modeled using ANSYS FLUENT computational fluid dynamics (CFD) commercial package. Heat transfer by radiation is fully accounted for by solving the radiative transport equation (RTE) using the discrete ordinate method. The results show that APS TBCs are better heat flux suppressors than EBPVD TBCs due to differences in the morphology of the porosity present within the TBC layer. Increased temperature drops across the TBC leads to temperature reductions at the TGO/bond coat interface which slows the rate of the thermally induced failure mechanisms such as CTE mismatch strain in the TGO layer, growth rate of TGO, and impurity diffusion within the bond coat.
