Denna rapport presenterar ett examensarbete på C-nivå där uppdragsgivaren har varit Hedemora Anpassning som bygger om och anpassar bilar för människor med olika funktionshinder. Företaget vill i framtiden ha möjlighet att erbjuda sina kunder ITS-tjänster. Målet med arbetet har varit att undersöka hur ITS skulle kunna stödja de funktionshindrade i deras bilkörning. Syftet delades upp i två delsyften, dels kartläggning av vilka tjänster som finns och är under utveckling inom området ITS – förarstöd och säkerhet samt hur de skulle kunna användas/anpassas för funktionshindrade dels att göra en undersökning av vilka behov de funktionshindrade har av ITS. De metoder som använts har varit kvalitativa intervjuer samt litteraturstudier. De senare har använts för att få inblick i ämnet ITS och tjänster som finns eller är under utveckling inom området. Intervjuerna gjordes med personer som endera arbetar med forskning inom ITS eller är verksamma inom området samt med funktionshindrade bilförare. En kartläggning av tjänster har skett och resultatet av intervjuerna pekar på att det finns ett behov av ITS-tjänster för funktionshindrade bilförare. Delvis finns behov av tjänster som redan finns i dag, till exempel navigationssystem. Det finns även behov av andra tjänster som är under utveckling. Gemensamt för dessa tjänster är att de i vissa fall skulle behöva anpassas till de funktionshindrade med röstanpassning eller andra specifika anpassningar.

Trichoderma are anamorphic fungi belonging to the class of Hifomicetos, also called imperfect fungi, or asexual conidial and whose gender Hypocrea teleomorph. They are free-living fungi, distributed throughout the world and found in different soil temperatures, especially those containing organic matter. Usually are not considered important human pathogens, but there are some reports indicating occasional pathogenicity of some species. Its easy handling and in vitro, stability and viability of colonies preserved this kind are a big target for biotechnology research. Because of these characteristics were isolated Trichoderma from plant Victoria amazonica, Rollinia sp. Murraya paniculata and Strychnos cogens; wood Scleronema micranthum, known as cardeiro; jatoba (Hymenaea courbaril), land of cubiu culture (Solanum sessiliflorum) and Indian black earth, in order to identify the molecular biology, the species level, such isolates and to assess their ability to produce cellulolytic enzymes. Of the 30 lines obtained were cultured spore, which were preserved in mineral oil, Castellani and method in 10% glycerol. From the suspension in glycerol, each sample was inoculated in 20ml of 10μL BD and cultivated 26oC, 100 rpm for 40:00 h. Next was extracted genomic DNA, performed PCR of specific regions of the ITS-1 and ITS-2 ribosomal DNA sequencing and subsequently. For the production of enzymes, the isolates were first grown in induction medium. Were inoculated 10μL of spore solution (glycerol 10%) in 50 mL of solution Manachini where the substratum was used to carboxymethylcellulose. The fungi were incubated at 27 ° C, 120 rpm for 120 hours. The dosage of CMCase was performed using the method of acid Dinitrosalicílico. For the determination of β-glucosidase was used p-nitrophenyl-β-D-glucopyranoside (PNPG) as substrate for the enzyme. The total protein concentration was determined by the Bradford method, using the reagent concentrate commercial Bio-RadTM and bovine serum albumin (ASB) as standard. The result of molecular identification of the first 13 samples revealed the species: T. harzianum, T. koningii, T. asperellum, T. viride, T. ovaslisporum, T. hamatum, T. piluliferum and T. koningiopsis, with a percentage between 96 and 99% identity and 100% reliability. The results indicated CMCase enzyme to low values, less than 0.100 U / mL with the exception of T. koningii (MPCE 10 3.2), T. harzianum (MPCE 2 2.2a), both isolates of M. paniculata, and isolate 1437 identified as Trichoderma sp., from Indian black earth, which showed slightly higher levels of 0.112 and 0.103 and 0.105 U / mL, respectively. For β-glucosidase, the results showed high activity in the vast majority of isolates with emphasis on T. harzianum MPCE 3 3.1 (10.45 U / mL) and T. piluliferum Vrc 2 3.2 (9.71 U / mL). All isolates produced protein in culture medium containing carboxymethylcellulose as substrate inducer
Trichoderma são fungos anamórficos pertencentes à classe dos hifomicetos, também chamados fungos imperfeitos, assexuais ou conidiais e que têm como teleomorfo o gênero Hypocrea. São fungos de vida livre, distribuídos em todo o mundo e encontrados em solos de diversas temperaturas, especialmente naqueles que contém matéria orgânica. Geralmente não são considerados importantes patógenos humanos, mas existem alguns relatos indicando patogenicidade ocasional em algumas espécies. Sua fácil manipulação e cultivo in vitro, estabilidade e viabilidade das colônias preservadas, fazem desse gênero um grande alvo para as pesquisas biotecnológicas. Por tais características, foram isolados Trichoderma das plantas Victoria amazonica, Rollinia sp., Murraya paniculata e Strychnos cogens; da madeira Scleronema micranthum, conhecida como cardeiro; de jatobá (Hymenaea courbaril), do solo de cultura de cubiu (Solanum sessiliflorum) e de terra preta de índio, com o objetivo de identificar, pela biologia molecular, em nível de espécie, tais isolados, bem como avaliar sua capacidade de produção de enzimas celulolíticas. Das 30 linhagens obtidas foram realizadas culturas monospóricas, as quais foram preservadas em óleo mineral, método Castellani e em glicerol 10%. A partir da suspensão em glicerol, de cada amostra foi inoculado 10μL em 20mL de BD e cultivado a 26oC, a 100 rpm por 40:00h. Em seguida foi extraído o DNA genômico, deste realizada a PCR específica para as regiões ITS-1 e ITS-2 do DNA ribossômico e posteriormente o sequenciamento. Para a produção de enzimas, os isolados foram previamente cultivados em meio indutor. Foram inoculados 10μL da solução de esporos (Glicerol 10%) em 50mL de solução de Manachini onde o substrato indutor utilizado foi a carboximetilcelulose. Os fungos foram incubados a 27°C, 120 rpm durante 120 horas. A dosagem de CMCase foi efetuada com base no método do Ácido Dinitrosalicílico. Para a dosagem de β-glucosidase foi utilizado o pnitrofenil- β-D-Glucopiranosídeo (pNPG) como substrato para a enzima. A concentração de proteínas totais foi determinada pelo método de Bradford, utilizando-se o reagente concentrado comercial da Bio-RadTM e albumina de soro bovino (ASB), como padrão. O resultado da identificação molecular das primeiras 13 amostras nos revelaram as espécies: T. harzianum, T. koningii, T. asperellum, T. viride, T. ovaslisporum, T. hamatum, T. piluliferum e T. koningiopsis, com um percentual entre 96 e 99% de identidade e 100% de confiabilidade. Os resultados enzimáticos para CMCase indicaram valores baixos, inferiores a 0,100 U/mL com exceção de T. koningii (MPCe 10 3.2), T. harzianum (MPCe 2 2.2a), ambos isolados de M. paniculata, e o isolado 1437 identificado como Trichoderma sp., proveniente de terra preta de índio, que apresentaram valores um pouco mais altos de 0,112 e 0,103 e 0,105 U/mL, respectivamente. Para β-glucosidase, os resultados apresentados mostraram alta atividade na grande maioria dos isolados com destaque para T. harzianum MPCe 3 3.1(10,45U/mL) e T. piluliferum Vrc 2 3.2 (9,71 U/mL). Todos os isolados produziram proteínas em meio de cultura contendo carboximetilcelulose como substrato indutor

O gênero Brasiliorchis inclui atualmente 14 espécies de orquídeas restritas ao bioma Mata Atlântica, ocorrendo desde Misiones, Argentina, até o Estado da Bahia, na região nordeste do Brasil.Embora estas espécies tenham sido tradicionalmente reconhecidas pelos seus caracteres vegetativos e principalmente florais, elas são morfologicamente muito similares e apresentam caracteres diagnósticos contínuos,assim, ousoexclusivo da morfologiapode não ser útil para identificação das espéciesneste grupo de orquídeas. Um estudo morfométrico anteriormente realizado com seis espécies deste gênero não conseguiu identificar agrupamentos claros. Amaioria dos caracteres analisados apresentou sobreposição entre diferentes espécies, sendo que apenas a espécie B. gracilisse mostrou distinta das demais. O objetivo desse estudo foi contribuir para aidentificação de linhagens evolutivamente distintas dentro do gênero e avaliar se os padrões filogenéticos de diversificação corroboram com o estudo morfométrico anteriormente realizado.Foram utilizados dados de sequências de plastídios (psbj-petA, atpl-atpH)e nucleares (ITS1-2) considerandoampla variação geográfica e morfológica observada no grupo. Foram amostrados 96 indivíduos,originados de 37 localidades de ocorrência no Brasil, incluindo 11 espéciesdo gênero. Análises de máxima parcimônia e bayesiana foram realizadas considerando os dados separadamente e concatenados.Os resultados suportam B. schunkeana como irmã de todas as outras espécies do gênero. B. barbozaefoi reconhecida como um grupo monofilético distinto, corroborando com os caracteres morfológicos diagnósticos desta espécie, e possivelmente irmão das espécies do complexo B. picta.A espécie B. gracilis não foi reconhecida como um grupo monofilético, não corroborando com o estudo de morfometria, na qual essa espécie se apresentou distinta das outras do complexo. Contudo, nas análises concatenadas alguns indivíduos apresentaram-se como irmãos das espécies do complexo B. picta. As espécies morfologicamente homogêneas pertencentes ao complexo B. picta (B. chrysantha, B. marginata, B. porphyrostele, B. ubatubana, B. phoenicanthera e B. picta) não formaram clados monofiléticos distintos. B. kautskyi e B. consanguinea, as quais são morfologicamente distintas, foram incluídas nos clados constituídos pelas espécies do complexo B. picta.Eventos de introgressão e hibridação podem ser potenciais causas da insuficiente resolução das árvores filogenéticas obtidas nesse estudo. Os padrões observados também sugerem que a separação das linhagens pode ter ocorrido recentemente e/ou rapidamente. Marcadores adicionais e análises de árvores de espécies podem ajudar a esclarecer os padrões de diversificação neste grupo.The genus Brasiliorchis currently includes 14 species of orchids occurring mainly in the Atlantic Forest Biome, from Misiones, Argentina, to the stateof Bahia, in northeastern Brazil. Although these species have been traditionally recognized by vegetative andmainly floral traits, they are morphologically very similar and display continuouscharacters, thus the exclusive use of the morphologycannot be useful for species identificationin this group of orchids. A morphometric study previously conducted with six species of this genus could not identify clear groupings. The majority of analyzed characters showed overlap between different species, with only the species B. gracilisbeing distinct from the others. The goals of this study were to contribute to the identification of evolutionary distinct lineages within the genus and assess if the phylogenetic patterns of diversification agree with a previous morphometric study available. Sequence data from plastid (psbj-petA, atpl-atpH) and nuclear (ITS1-2)regions were used considering wide morphological and geographical sampling variation. We sampled 96 individuals, originated from 37 sites of occurrence in Brazil, including 11 species of the genus. Bayesian and parsimony analyses were performed considering data separately and concatenated. The results support B. schunkeana as sister to all other species of the genus. B. barbozaewasrecognized as a monophyletic group,corroborating with morphological diagnostic characters of this species,and possibly sisters of the complex species B. picta.The species B. gracilis was not recognized as a monophyletic group, not agreeing with the morphometry study, which showed this species as being distinct from the other species in the complex. However, in the concatenated analysis, some individuals presented themselves as sisters of the species complex B. picta. The morphologically homogeneous species belonging to the B. picta complex (B. chrysantha, B. marginata, B. porphyrostele, B. ubatubana, B. phoenicanthera e B. picta) did not form distinct monophyletic clades. B. kautskyi and B. consanguinea, which are morphologically clearly distinct, are embedded in clades consisting of the B. pictaspecies complex.Hybridization and introgression events may be potential causes of insufficient resolution of phylogenetic trees obtained in this study. The observed patterns also suggest that the separation of the lineage may have occurred recently and/or quickly.Additional markers and species tree analyses may help clarify diversification patterns in this group.

Testo completoAbstract (sommario):
Le nombre de véhicules connectés augmentent et pour une utilisation plus intelligente des systèmes de transport, les véhicules ont besoin d’accroître leur connaissance de l’environnement. Cela peut être atteint en permettant aux véhicules de communiquer avec leur environnement. Pour une connectivité omniprésente, il sera nécessaire d’utiliser diverses technologies sans fil, existantes. Dans un tel environnement de réseau d’accès hétérogène, il est nécessaire de fournir aux applications des mécanismes décisionnels transparents pour gérer l’affectation des flux de données sur les réseaux disponibles. Dans cette thèse, nous proposons le Ant-based Decision Maker for Opportunistic Networking (AD4ON), un Decision Maker (DM) mécanisme modulaire capable de choisir le meilleur profil de communication disponible pour chaque fluxde données dans un environnement de réseau hétérogène et dynamique. Le mécanisme proposé gère les exigences et préférences de différents acteurs (applications, utilisateurs,etc.), ainsi que les information réseaux dans un futur proche, afin de prendre des décisions plus intelligentes. C’est-à-dire, afin d’augmenter la satisfaction de chaque acteur impliqué dans le processus de communication, ainsi que d’augmenter la stabilité de la décision (par exemple, en réduisant l’effet “ping-pong“)Demand from different actors for extended connectivity where vehicles can exchange data with other devices have pushed vehicle manufacturers to invest in embedded solutions, which paves the way towards Cooperative Intelligent Transportation Systems (C-ITS). Cooperative vehicles enable the development of an ecosystem of services around them. Due to the heterogeneousness of such services and their specific requirements, for ubiquitous connectivity it is necessary to combine existing wireless technologies, providing applications with a communication architecture that hides such underlying access technologies specificities. Moreover, due to vehicles’ high velocity it is needed a Decision Maker (DM) mechanism capable to take into account the short-term prevision about network environment in order to better manage all flow communications. Based on the Intelligent Transportation Systems (ITS) architecture proposed by International Organization for Standardization (ISO), we proposed the Ant-based Decision Maker for Opportunistic Networking (AD4ON), a modular decision maker mechanism capable to choose the best available access network for each data flow in an heterogeneous and dynamic network environment. The proposed mechanism manages requirements and preferences from different actors, taking into account the short-term prevision about the network environment. Simulations have demonstrated that the AD4ON outperforms current benchmark algorithms, by increasing decision’s stability, reducing the “ping-pong” effect and maximizing flow’s satisfaction. Moreover, we demonstrate that taking into account the short-term prevision, the AD4ON can optimize the algorithm reaction time

Testo completoAbstract (sommario):
Intelligent Transportation Systems (ITS) have attracted an increasing amount of attention in recent years. Thanks to the fast development of vehicular computing hardware, vehicular sensors and citywide infrastructures, many impressive applications have been proposed under the topic of ITS, such as Vehicular Cloud (VC), intelligent traffic controls, etc. These applications can bring us a safer, more efficient, and also more enjoyable transportation environment. However, an accurate and efficient traffic flow prediction system is needed to achieve these applications, which creates an opportunity for applications under ITS to deal with the possible road situation in advance. To achieve better traffic flow prediction performance, many prediction methods have been proposed, such as mathematical modeling methods, parametric methods, and non-parametric methods. It is always one of the hot topics about how to implement an efficient, robust and accurate vehicular traffic prediction system.
With the help of Machine Learning-based (ML) methods, especially Deep Learning-based (DL) methods, the accuracy of the prediction model is increased. However, we also noticed that there are still many open challenges under ML-based vehicular traffic prediction model real-world implementation. Firstly, the time consumption for DL model training is relatively huge compared to parametric models, such as ARIMA, SARIMA, etc. Second, it is still a hot topic for the road traffic prediction that how to capture the special relationship between road detectors, which is affected by the geographic correlation, as well as the time change. The last but not the least, it is important for us to implement the prediction system in the real world; meanwhile, we should find a way to make use of the advanced technology applied in ITS to improve the prediction system itself.
In our work, we focus on improving the features of the prediction model, which can be helpful for implementing the model in the real word. Firstly, we introduced an optimization strategy for ML-based models' training process, in order to reduce the time cost in this process. Secondly, We provide a new hybrid deep learning model by using GCN and the deep aggregation structure (i.e., the sequence to sequence structure) of the GRU. Meanwhile, in order to solve the real-world prediction problem, i.e., the online prediction task, we provide a new online prediction strategy by using refinement learning. In order to further improve the model's accuracy and efficiency when applied to ITS, we provide a parallel training strategy by using the benefits of the vehicular cloud structure.

Fungos endofíticos são micro-organismos que habitam o interior da planta hospedeira, sem causar danos aparentes ou estruturas externas visíveis. O coqueiro (Cocos nucifera L.) é uma espécie tropical, largamente distribuída na Ásia, África, América Latina e regiões do Pacífico, sendo o Brasil o quarto maior produtor mundial. Devido à importância agroeconômica do coco, este trabalho teve por objetivo determinar a micobiota endofítica de folhas sadias de C. nucifera em duas cultivares (Anão-amarelo e Anão-verde) e um híbrido (PB 121) em Goiana, Pernambuco. No laboratório, fragmentos de raque e folíolo foram lavados com água corrente e sabão neutro, e com auxílio de um furador esterilizado foram feitos discos foliares (6 mm), posteriormente desinfestados em álcool 70% por 1 minuto, em hipoclorito de sódio (NaOCl) a 2% por 2 minutos e 30 segundos, em álcool 70% por 30 segundos e finalmente duas lavagens com água destilada esterilizada. Os fragmentos foram tranferidos para placa de Petri, em triplicata, contendo Batata-Dextrose-Ágar (BDA) acrescido de cloranfenicol (50 mg.L-1). Foram sequenciados a região ITS do rDNA dos isolados e em seguida verificada a similaridade Blastn e realizada análises filogenéticas. Índices de diversidade, curva de acumulação de espécies, similaridade e frequência de ocorrência foram calculados. O total de 1296 fragmentos de folhas/raques foram analizados e 474 espécimes de fungos endofíticos foram isolados e distribuídos em 31 gêneros e 37 espécies. A espécies identificadas são representantes do filo Ascomycota, pertencentes às classes Sordariomycetes, Dothideomycetes e Eurotiomycetes, além de Occultifur externus, Rhodotorula marina e Pseudozyma hubeiensis anamorfos do filo Basidiomycota e Syncephalastrum racemosum do filo Zygomycota. Arthrinium xenocordella, Ascotricha guamenses, Phlyctaeniella sp., Pyrenochaetopsis decipiens, P. leptospora e Stenella musae são citadas pela primeira vez como endofíticos. Fusarium proliferatum, F. solani e Paecilomyces lilacinus são reportadas pela primeira vez como endofíticos em Cocos nucifera.

Tsagouria, P. "The polis, its coinage and its historians". Thesis, University College London (University of London), 2006. http://discovery.ucl.ac.uk/1445887/.
Testo completoAbstract (sommario):
This thesis sets out to explore whether the Greeks had a concept of economics and whether it is appropriate to talk about the polis economy. These issues are explored, first by studying Greek coinage and economic practices related to polis public finance and, second, by studying Greek historians' understanding of economics. In the latter case, we consider Herodotus' treatment of the economics of the Persian Wars as well as Thucydides' and Xenophon's treatment of the economics of the Peloponnesian War. From the study of economics in Greek historiography, it is maintained that Herodotus, Thucydides and Xenophon were not only interested in economics but also understood war economics. This is due to the dominance of naval warfare especially in the last years of the Peloponnesian War, which resulted in the monetization of the polis economy. However, we claim that the above historians in varying degrees failed to encapsulate the ramifications of the polis economy and its complexity, because there is a disparity between the reality of the polis economy and its interpretation by the historians. Thus any reconstruction of the polis economy and of the rationale for economic practices based on fifth century Greek historiography is limited and insufficient. It is for this reason that we have studied Greek coinage and certain economic practices employed by the polis to manage public finances, finance public expenditure and deal with economic crises. From this study, we argue that the polis economy was a rational and independent institution operating within the polis. In a nutshell, the main conclusion of this thesis is that although the understanding of economic factors was 'embedded' in the prevailing ideology of wealth and money, there was indeed a polis economy as an independent institution.

Testo completoAbstract (sommario):
The molecular characterization of twenty six Theileria spp. isolates and one C. felis isolate were done on the small subunit ribosomal RNA (SSU rRNA) gene, the 5.8S gene, and the two internal transcribed spacer regions using gDNA. The SSU rRNA gene is increasingly accepted as a widely used marker for characterization, taxonomic classification, and phylogenetic analysis and this gene has been sequenced from a variety of different organisms, resulting in a large database for sequence comparisons (Chae et al. 1998; Chae et al., 1999 a,b,c; Stockham et al., 2000; Cossio-Bayugar et al., 2002; Gubbels et al., 2000). The genomic region consists of the internal transcribed spacer 1 (ITS 1), the 5.8S gene, and internal transcribed spacer 2 (ITS 2) (ITS 1-5.8S-ITS 2 gene region) and separates the SSU rRNA gene from the large subunit ribosomal RNA gene. The 5.8S rRNA gene is highly conserved in size and nucleotide sequence, is relatively constant in molecular weight, and has an average chain length of approximately 160 nucleotides and has proven useful in dividing subgenera of Gyrodactylus ((Nazar, 1984; Zietara et al., 2002).
Pairwise comparisons were done between the clones of an individual isolate and among the clones of the different isolates. Phylogenetic trees were made from the resulting sequences. This study shows that different SSU rRNA genes may be associated with ITS 1-5.8S-ITS 2 gene regions of distinct sequence in the same isolate. This study also demonstrates that considerable ITS 1-5.8S-ITS 2 gene region sequence variation may exist within a species. This may be useful for subspeciation designation, or may simply reflect considerable variation within the population. This study shows that the ITS 1-5.8S-ITS 2 gene region may be a useful molecular marker for the taxonomy of Theileria spp.

Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgicoClassificaÃÃes taxonÃmicas de ostras sÃo problemÃticas, pois estes organismos possuem caracterÃsticas morfolÃgicas pouco informativas. A variabilidade da regiÃo ITS do cluster ibossÃmico tem sido bastante utilizada em estudos filogenÃticos e taxonÃmicos, visto que esta regiÃo apresenta uma variabilidade relativamente elevada e fÃcil amplificaÃÃo por termociclagem. A ostra Crassostrea brasiliana foi, por dÃcadas, confundida com C. rhizophorae, entretanto, estudos recentes indicam que sÃo duas espÃcies biologicamente distintas. Esta pesquisa objetivou analisar a variabilidade da regiÃo ITS-1 de populaÃÃes de ostras C. rhizophorae em trÃs estuÃrios da costa do Estado do Cearà e investigar a presenÃa de uma segunda espÃcie de ostra pertencente ao gÃnero Crassostrea. Exemplares da ostra nativa C. cf. rhizophorae foram coletados nos estuÃrios da costa cearense para anÃlise de variabilidade populacional. Foram coletados tambÃm espÃcimes de C. cf. brasiliana para estudo de filogenia e comparaÃÃo com o primeiro grupo de ostras. ApÃs extraÃÃo de DNA e amplificaÃÃo por PCR da regiÃo ITS-1, seqÃÃncias desta regiÃo foram obtidas para anÃlise filogenÃtica realizada atravÃs dos mÃtodos de neighbour-joining e mÃxima parcimÃnia. SequÃncias de ITS-1 descritas no GenBank para 35 indivÃduos, representando 12 espÃcies de ostras do gÃnero Crassostrea, e mais duas seqÃÃncias de Saccostrea glomerata (grupo externo), foram utilizadas para os alinhamentos com as sequÃncias obtidas na presente pesquisa. A variabilidade intraespecÃfica de C.cf.rhizophorae foi estudada pelo mÃtodo da mÃxima parcimÃnia. SeqÃÃncias inÃditas de ITS-1 completo foram obtidas para C.brasiliana e C.rhizophorae, com 427 e 439 pb, respectivamente. A Ãrvore de neighbour-joining evidenciou a clara separaÃÃo de C.cf.brasiliana e C.cf.rhizophorae em ramos distintos (100%), confirmando a ocorrÃncia de, pelo menos, duas espÃcies de Crassostrea no local de estudo. O estudo sugere a ocorrÃncia de C.brasiliana no Estado do CearÃ. Embora alguns autores tenham considerado C.brasiliana sinÃnimo de C.virginica, em nosso estudo, C.virginica mostrou-se muito mais prÃxima de C.rhizophorae, com forte agrupamento (100%). A Ãrvore de mÃxima parcimÃnia mostrou que as seqÃÃncias de C.cf.brasiliana e C.cf.rhizophorae formaram um grupo monofilÃtico com as demais espÃcies de Crassostrea em 100% das repetiÃÃes. C.cf.brasiliana apresentou-se na base do ramo monofilÃtico de Crassostrea e, portanto, foi o grupo mais prÃximo de S.glomerata. Esta Ãrvore tambÃm mostrou a separaÃÃo dos exemplares de C.cf.brasiliana e C.cf.rhizophorae em ramos distintos (100%), evidenciando o forte sinal filogenÃtico observado na anÃlise. Novamente, C.cf.rhizophorae mostrou-se prÃxima de C.virginica. A anÃlise de mÃxima parcimÃnia para variabilidade intraespecÃfica de C.cf.rhizophorae nos trÃs estuÃrios estudados mostrou a formaÃÃo de 7 diferentes sequÃncias para C.cf.rhizophorae. A ligaÃÃo entre as sequÃncias encontradas sugere a presenÃa de fluxo gÃnico entre as populaÃÃes estudadas e a ocorrÃncia de sequÃncias exclusivas pode indicar a formaÃÃo de populaÃÃes residentes em cada um dos estuÃrios analisados. A regiÃo ITS-1 mostrou-se ideal para estudos de filogenia de ostras e estudos de variabilidade gÃnica populacional. A confirmaÃÃo de uma segunda espÃcie de ostra pertencente ao gÃnero Crassostrea na costa cearense à relevante para uma melhor gestÃo destes recursos, que possuem grande importÃncia ecolÃgica, econÃmica e social para nosso Estado.
Taxonomic classifications of oysters are problematic, because these bodies have little morphological information. The variability of the ITS region of the cluster ibossÃmico has been used in phylogenetic and taxonomic studies, since this region presents a relatively high variability and easy amplification by thermocycling. The oyster Crassostrea brasiliana was, by decades, confused with C. rhizophorae However, recent studies indicate that two biologically distinct species. This study aimed to analyze the variability of ITS-1 region of oyster populations of C. rhizophorae in three estuaries on the coast of Cearà State and investigate the presence of a second species of oysters belonging to the genus Crassostrea. Copies of the native oyster C. cf. rhizophorae were collected in the estuaries of the coast of Cearà for the analysis population ariability. Were also collected specimens of C. cf. brasiliana for study of phylogeny and compared with the first group of oysters. After extraction of DNA and amplification by PCR of the ITS-1 region, this region sequences were obtained for phylogenetic analysis performed by the methods of neighbor-joining and maximum parsimony. ITS-1 sequences described in GenBank for 35 individuals representing 12 species of oysters of the genus Crassostrea and two sequences of Saccostrea glomerata (external group) were used for the alignments with the sequences obtained in this study. The intraspecific variability of C.cf.rhizophorae was studied by the method of maximum parsimony. Unpublished sequences of ITS-1 were obtained for full C.brasiliana and C.rhizophorae with 427 and 439 bp, respectively. The neighbor-joining tree, showed the clear separation of C.cf.brasiliana and C.cf.rhizophorae in separate branches (100%), confirming the occurrence of at least two species of Crassostrea place of study. The study suggests the occurrence of C.brasiliana in the state of CearÃ. Although some authors have considered C.brasiliana synonymous with C.virginica in our study, C.virginica was very close to C.rhizophorae, with a strong group (100%). The tree of maximum parsimony showed that the sequences of C.cf.brasiliana and C.cf.rhizophorae formed a monophyletic group with other species of Crassostrea in 100% of replicates. C.cf.brasiliana presented on the basis of branch of Crassostrea monophyletic and, therefore, was the group nearest S.glomerata. This tree also showed the separation of the copies of C.cf.brasiliana and C.cf.rhizophorae in different branches (100%), showing the strong signal observed in the phylogenetic analysis. Again, C.cf.rhizophorae showed up near C.virginica. The maximum parsimony analysis of intraspecific variability of C.cf.rhizophorae for the three estuaries studied showed the formation of 7 different sequences for C.cf.rhizophorae. The connection between the sequences found suggests the presence of gene flow between populations and the occurrence of unique sequences may indicate the formation of resident populations in each of the estuaries examined. The region ITS-1 proved to be ideal for studies of phylogeny of oysters and studies of population genetic variability. Confirmation of a second species of oysters belonging to the genus Crassostrea in Cearà coast is important for better management of these resources, which have important ecological, economic and social to our state.

Chia, Philip P. Y. "The thought of Qoheleth : its structure, its sequential unfolding, and its position in Israel's theology". Thesis, University of Sheffield, 1988. http://etheses.whiterose.ac.uk/10189/.
Testo completoAbstract (sommario):
This study analyses the theological thought of Qoheleth. In the Introduction, a survey of Qoheleth studies in the last hundred years has shown that the literary structure of the book of Qoheleth is still crucial to the understanding of the theological thought of Qoheleth. Thus, Chapter One of this thesis Is devoted to discussing various approaches, i.e. traditional critical, form critical, and modern literary approaches, which have been employed in the study of the structure of the book. Chapter Two analyses the structure of Qoheleth's theological thought, arguing that '7]T (the absurd) and fflri (joy) are the two concepts which make sense of Qoheleth's thought and also form the fundamental structure of his thought. Together with various secondary themes such as portion, profit, wisdom, wealth, death, remembrance and God, they form the total structure of Qoehleth's thought. This is followed by a reading of Qoheleth in Chapter Three, analysing the argument of the book as it develops. Chapter Four examines the position of Qoheleth's theological thought within Israel's theology. The relationships between Wisdom and Yahwism, and Wisdom and Creation are analysed, arguing that the idea that Wisdom theology is essentially Creation theology is not compatible with Qoheleth's thought. The theology of Qoheleth is to be determined by the book itself, and proves to reflect neither conservative Yahwism nor radical anti-Yahwism. The uniqueness of Qoheleth's thought leads to the identification of Qoheleth as a 'liminal intellectual' who may be going through a period of transition, in the process of adopting a new set of beliefs, social norms or status. Thus. Qoheleth's theological thought may be seen as a 'liminal' theology, with 'liminality' as its social setting.

Testo completoAbstract (sommario):
The genus Iliamna Greene has a taxonomically complex history. Since its desciption in 1906, the genus was not recognized for some time, several species were initially placed into other genera, and the species status of a few was questioned. Today, eight species of Iliamna are recognized. Six species are located in western North America and two are found isolated to the east. Species in Iliamna are very similar morphologically with only a few characters distinguishing several as separate entities. The need for systematic study became apparent since all but one species are considered rare or endangered. Also, the differentiation between two endangered species, I. corei and I. remota, was unclear in a previous study using random amplified polymorphic DNA fragments. Of the western species, four overlap in distribution (I. crandallii, I grandi ora, I. longisepala, and I. rivularis) and their recognition as separate species has been questioned. The focus of this study was to develop a phylogeny for Iliamna using sequences from the internal transcribed spacer region (ITS) of the nuclear ribosomal
RNA genes in order to determine its biogeographical and evolutionary history. Cladistic analysis was performed and the resulting phylogeny is presented. The ITS data provide new insights in the origination of the genus and its distribution. In Iliamna, the ITS region is 677 base pairs long with 120 sites providing information in the formation of phylogenetic trees. Iliamna forms a well-supported clade distinct from related genera and is monophyletic. Three well-supported groups are formed. One contains representatives from the Pacific Northwest. Another contains all of the remaining species with the third clade nested therein. This last clade contains the two eastern species, I. corei and I. remota, but there is not enough variability to support the divergence of these taxa as distinct species. There is also not sufficient variability in the ITS region to identify the western species I. crandallii, I. grandi ora, I. longisepala and I. rivularis as distinct entities.Master of Science

No Brasil as espécies D. flavipennella e D. saccharalis tem uma grande importância para o setor sucroalcooleiro por causar danos em cana-de-açúcar. Os estágios de ovo, larva, pupa e adulto são muito parecidos entre essas espécies e a identificação pode ser confusa. O Espaçador Interno Transcrito 2 (ITS2) do locus DNA ribossomal, que tem um papel importante no processamento do DNAr, vem sendo aplicado em estudos filogenéticos e populacionais por ter como característica divergência evolutiva. Este trabalho tem como objetivo compreender o grau de divergência evolutiva entre as espécies D. flavipennella e D. saccharalis com base no marcador ITS 2, analisar sua estrutura e características funcionais. O DNA foi extraído de amostras de ovo, lagarta e adulto. Foi realizada PCR e os amplicons foram purificados e sequenciados. As sequências foram analisadas com o programa MEGA 5.01. O tamanho do ITS 2 foi de 410 pb em D. flavipennella e 448 pb em D. saccharalis. O conteúdo de GC foi similar entre as duas espécies. As sequências apresentaram regiões conservadas intercaladas por regiões variáveis. Algumas regiões conservadas apresentavam motivos presentes também em espécies de diferentes grupos, provavelmente associados às estruturas participantes no processamento do RNA pós-transcricional. Três repetições microssatélites estavam presentes em D. saccharalis e ausentes em D. flavipennella, contribuindo para a diferença de tamanho entre as duas espécies. Apesar da divergência existente entre as sequências das espécies, existem regiões que são conservadas em níveis taxonômicos mais altos.

Testo completoAbstract (sommario):
The thesis attempts a portrait of The Cloud in the context of its position in the history of Christian mysticism. That the anonymous work owed much to spiritual writers of the preceding twelve hundred years is not debatable; what it owed maybe slightly less obvious. The Cloud is essentially a work of Dionysian mysticism, and various writers within that tradition who may have influenced or affected the teaching of The Cloud are examined. At the same time, however, the anonymous writer owes much to the western tradition of Augustinian theology, and the role of this, complementary to the Dionysian mysticism, is also considered. In Chapter II we look at the theological doctrine underlying the mystical doctrine of the Cloud corpus. Chapter III has two major parts, both concerned with the influence of The Cloud on the subsequent development of spiritual writing in England. The first considers the relationship with Walter Hilton. The second examines aspects of Puritan thought which may indicate that the influence of The Cloud, after the Reformation, was not restricted to Catholic thought.

Testo completoAbstract (sommario):
At the Edinburgh University Collection of Historical Instruments (EUCHMI) there are two virginals where the strings are plucked extremely close to 1/4 of their length over a substantial part of the compass. Principles of Acoustics dictate that in such cases the fourth partial of the resulting sound is unlikely to be produced with any appreciable magnitude. Similar situations affecting different partials also occur when the plucking point is located at other fractional parts of the string length, such as 1/3 or 1/5. A database of plucking points, based on museum catalogues, was created and analysed, so that pitch regions are identified where such phenomena are likely to occur for different categories of instruments. The main cue used in harpsichord tuning is related to beat phenomena produced by partials of two simultaneously played notes, whenever there is a small difference between their frequencies. Partial four being relevant for major thirds and perfect fourths, these intervals may result less accurate, or less reliably tuned, in instruments like the above virginals. Historical sources were surveyed for expressions which describe the cues that tuners were supposed to use in identifying the ideal of an interval. Although expressions such as Schwebungen are mostly related with beats, broader meanings are discussed. Hints of the use of alternative, not beat-related cues, are identified. A series of practical tuning experiments was performed in which selected intervals were tuned, the accuracy of the tuning process being assessed from recordings, which were subjected to spectral analysis. Only cues that could be related to historical sources were used. The effects of factors such as pitch, pitch region, instrument, interval type, and particularly the potential absence of relevant partials were investigated, statistical methods playing a substantial role in the research. A logbook was created, where the experimenter detailed the cues used for each tuned interval in one of the experiments. The recorded information provided some insight into a number of strategies a tuner may use for coping with difficulties in cases of absent or weak partials. The impact of inharmonicity on the exact size of just intervals was also examined, both on theoretical grounds and based on data from the experiments. A number of case studies were included, where a comparison was made between missing partial notes predicted from plucking points and the degree of absence of those partials in the actual spectra for some historical instruments.

I n a world of continuous technological growth, the discovery of plastic materials was warmly welcomed. Indeed, they opened new possibilities and revolutionized industrial
manufacture of everyday life goods.
The almost incontrollable growth of polymeric materials industrial production, however, brought along the problem of disposal of end-life plastic objects. The increasing necessity of facing the worrying plastic pollution phenomenon, pushed researchers to find environ- mentally friendly polymers, in order to replace the commonly-used oil-derived ones. Among all biopolymers, polylactic acid (PLA) was found to be one of the most attractive. In particular, PLA monomer, i.e. lactic acid, can be extracted from natural sources and PLA itself is fully biodegradable to unharmful byproducts. Polylactic acid is also character- ized by good processability, but its poor toughness and thermal stability are strong hurdles for its wide industrial applicability.
For this reason, PLA-related research is usually aimed at improving its lacking properties, while preserving its good features. The PhD thesis here presented fits in this field. In par- ticular, two strategies were studied, namely the preparation of bionanocomposites and the use of alternative synthetic methodologies.
From one side, the use of different cellulose-based nanofillers was investigated and resulted in the production of fully biodegradable and biocompatible nanocomposites with improved properties over standard PLA.
On the other hand, O-carboxyanhydrides (OCAs) and 1,3-dioxolane-4-ones (DOX) were studied as alternative monomers for the synthesis of highly functionalized polyester-based materials with tailored properties.

Testo completoAbstract (sommario):
Building from an export information processing framework this research work particularly focuses on the quality of export memory, its determinants, its subsequent use in decision-making, and its ultimate relationship with export performance. Within export memory use, four export memory use dimensions have been discovered: instrumental, conceptual, legitimizing and manipulating. Results from the qualitative study based on the data from a mail survey with 354 responses reveal that the development of export memory quality is positively related with quality of export information acquisition, the quality of export information interpretation, export coordination, and integration of the information into the organizational system. Several company and environmental factors have also been examined in terms of their relationship with export memory use. The two factors found to be significantly related to the extent of export memory use are acquisition of export information quality and export memory quality. The results reveal that export memory quality is positively related to the extent of export memory use which in turn was found to be positively related to export performance. Furthermore, results of the study show that there is only one aspect of export memory use that significantly affects export performance – the extent of export memory use.

Resumo: Poecilanthe (Leguminosae, Papilionoideae, Brongniartieae) é em gênero sul-americano que inclui atualmente dez espécies. A heterogeneidade morfológica e química encontrada em Poecilanthe dificulta sua circunscrição e coloca em dúvida sua monofilia. Além disso, limites interespecíficos imprecisos e falta de chave de identificação dificultam o reconhecimento das espécies. Este trabalho tem como objetivos testar a monofilia de Poecilanthe e estabelecer as relações entre suas espécies, bem como revisar a taxonomia do gênero. Para tanto, uma análise filogenética de máxima parcimônia baseada em caracteres morfológicos e seqüências de ITS/5.8S (nrDNA) foi realizada. Como subsídio para a análise cladística, foi feito um estudo sobre a morfologia das sementes e embriões de Poecilanthe, que resultou no reconhecimento de quatro padrões distintos de morfologia. Os resultados da filogenia mostram que Poecilanthe não é um gênero monofilético, sendo composto por três clados parafiléticos em relação à tribo. Estes três clados foram caracterizados morfologicamente e considerados como gêneros distintos. Poecilanthe é recircunscrito para incluir apenas as espécies extra-amazônicas (Poecilanthe s.s.), compreendendo então seis espécies. O gênero Amphiodon é restabelecido, e P. ovalifolia combinada neste. Um gênero novo é descrito para incluir P. amazonica e P. hostmannii. Cada um destes gêneros foi tratado taxonomicamente, constando em cada tratamento descrições, ilustrações e chave para a identificação das espécies
Abstract: The genus Poecilanthe (Leguminosae, Papilionoideae, Brongniartieae) currently comprises ten South-American species. The morphological and chemical diversity that is found within this genus renders its circumscription imprecise and brings Poecilanthe¿s monophyly into question. This work aims to test the monophyly of Poecilanthe and to revise the taxonomy of the genus. A parsimony analysis based on both morphological and ITS/5.8S data was carried out. In order to provide characters to the cladistic analysis, the morphology of the seeds and embryos of Poecilanthe was analyzed, and resulted in the identification of four different morphological patterns. The phylogeny does not support Poecilanthe as monophyletic, but resolves three different well-supported lineages that are paraphyletic with respect to the tribe. These clades are morphologically characterized and ranked at the generic level. Poecilanthe is recircumscribed to include the six extra-Amazonian species only. The genus Amphiodon is reinstated and P. ovalifolia is combined. Poecilante amazonica and P. hostmannii are segregated into a new genus. Each genus was revised and descriptions, illustrations and identification key for the species are presented.

Testo completoAbstract (sommario):
This study examines the benefits of Cooperative Intelligent Transport Systems (C-ITS) in weaving sections. The research proposes a lane-changing advisory application to alleviate the lane-changing concentration in weaving sections by coordinating weaving vehicles. While non-weaving vehicles travel as normal, weaving vehicles are monitored and advised through personalized messages based on their destination lane. The findings of this research, derived from a microscopic simulation in AIMSUN, reveal that the proposed strategy has the potential to improve delay significantly and that it can be applied to any existing one-sided weaving sections.

Testo completoAbstract (sommario):
The swelling mechanisms of U3Si2 under neutron irradiation in reactor conditions are not unequivocally known. The limited experimental evidence that is available suggests that the main driver of the swelling in this material would be fission gases accumulation at crystalline grain boundaries. The steps that lead to the accumulation of fission gases at these locations are multiple and complex. However, gradually, the gaseous fission products migrate by diffusion. Upon reaching a grain boundary, which acts as a trap, the gaseous fission products start to accumulate, thus leading to formation of bubbles and hence to swelling. Therefore, a quantitative model of swelling requires the incorporation of phenomena that increase the presence of grain boundaries and decrease grain sizes, thus creating sites for bubble formation and growth. It is assumed that grain boundary formation results from the conversion of stored energy from accumulated dislocations into energy for the formation of new grain boundaries.This thesis attempts to develop a quantitative model for grain subdivision in U3Si2 based on the above mentioned phenomena to verify the presence of this mechanism and to use in conjunction with swelling codes to evaluate the total swelling of the pellet in the reactor during its lifetime.

Testo completoAbstract (sommario):
Ethnonational movements have proliferated throughout the world since the American and French Revolutions first gave birth to the consciousness that every nation has a right to self-determination. Whether these ethnic-based nationalist movements are a new phenomenon which is rooted in the Industrial Era of Europe, or are just a recent stage in an ethnic struggle that began during the initial cultural contact between two ethnically different groups and has persisted ever since, determines the point at which an analyst will choose to begin his or her investigation. Ultimately, the selection of this starting point determines the conclusions drawn about the cause and nature of ethnonational movements.
In this thesis, the exploration of Irish ethnonationalism begins in the twelfth century when the Anglo-Normans invaded Ireland. The formation and development of the Irish ethnic group is analyzed, and self-identification found to be the key criterion for determining group membership. As social cleavages between the "Irish" and "colonizer" hardened, institutions and structures emerged to maintain and reinforce the ethnic boundary between these two groups. The thesis concludes with a detailed analysis of the operation of one mechanism of self-segregation--separate education—using ethnographic data and autobiographical accounts of the childhood experiences of people who were born and raised in Northern Ireland.
In this thesis, it is argued that Irish ethnic consciousness was brought into awareness when the invading Anglo-Normans threatened to dissolve into chaos the existing Gaelic social order. It is contended that the ethnic struggle in Ireland which began in the twelfth century and still persists today in Northern Ireland, has no single cause, but was and still is fundamentally a cultural conflict which continues to be fuelled by a long history of "remembered" grievances—cultural, political, and economic--most of which predate industrialization and the American and French Revolutions. This past is kept alive by the institutions, structures, and practices which maintain and reinforce the ethnic boundary between Catholics and Protestants in contemporary Northern Ireland, thus ensuring that the Irish nationalist movement will continue to have at its disposal a sharply defined ethnic group which it can mobilize when necessary, and from which it can recruit new members.Arts, Faculty of

Testo completoAbstract (sommario):
This research project was a study of the non-auditioned, mixed collegiate choral ensemble. The investigation focused on successful ensembles of this type at five universities in the midwestern United States. The purpose of the study was to investigate the ensemble's need for existence and its function within the university's choral program, to research teaching strategies that work with such a unique ensemble, and to discover tactics which help this type of group reach its full potential. Information for the study was garnered through observations of the five choirs, through surveys of the group participants, and through interviews with the conductors.A total of 372 participants completed surveys. The surveys contained a variety of questions regarding group demographics, reasons for participating, rehearsal techniques, repertoire, and benefits of participating. Responses were compiled and then analyzed for similarities and differences. Three types of statistical tests were utilized to discover if significant differences existed. For those responses which were of a nominal nature, a chisquare test was used to determine if there was any significant interaction between the responses and the various ensembles. For those responses which were of a numerical nature, an Analysis of Variance (ANOVA) test was performed to determine if there were any significant differences among the choirs. If significant differences were detected (p<.05), a Tukey HSD post hoc test was utilized to determine where the differences occurred. For those questions which were of a qualitative nature, responses were simply compiled and compared for similarities and differences.The five conductors were interviewed and questioned regarding the purpose of their ensemble, the type of teaching strategies they incorporate, the structure of their rehearsals, any methods of motivation and reinforcement they use, and what techniques they use to help the ensemble reach its full potential.Some similarities were discovered among the five choirs, with the most striking one being the high level of satisfaction among the participants. Significant differences were also discovered between the choirs in a variety of areas, including reasons for participating, group perception, evaluation of the conductor's rehearsal techniques, and productivity of the rehearsal.School of Music

Resveratrol (RES) has been associated with numerous pharmacological effects. Yet its pharmacokinetics is not clearly understood. It is known to get extensively metabolized into its sulfated and glucuronidated metabolites and has very low circulating RES concentrations in plasma. Although the concentrations of conjugated metabolites of RES have been reported to be much greater than that of RES, they have not been evaluated. This also becomes important in light of positive biological activities reported for sulfated metabolites of RES. Conjugation is a complex process which can sometimes be a reversible process and needs comprehensive evaluation to better understand RES and its metabolites' disposition. There has been a debate among the researchers regarding the differences in kinetics of preformed versus in vivo formed metabolites in the light of guidelines issued by regulatory bodies regarding metabolites in safety testing (MIST). We have addressed the above questions in this work, in addition to evaluating brain permeability of a potent RES analog, trimethoxy-trans-stilbene (TMS). Chapter 1 presents a detailed introduction, hypothesis and significance of my work. Chapter 2 includes the development and validation of a bioanalytical method for quantitation of RES and its metabolites on LC/MS/MS. We were able to develop and validate a robust bioanalytical method to quantitate RES and its four major metabolites resveratrol-4'-glucuronide (R4'G), resveratrol-3-glucuronide (R3G), resveratrol-4'-sulfate (R4'S) and resveratrol-3-sulfate (R3S). In Chapter 3, lung as a possible metabolizing organ for RES was evaluated. This study was performed in vivo in mouse model using multiple site of administration and single site of sampling approach. In vitro studies were also performed to confirm the in vivo results. Inter species differences in RES pulmonary metabolism were also studied. We observed lungs to be the major metabolizing organs for RES with inter species differences in its metabolism. Chapter 4 provides detailed pharmacokinetics of sulfated metabolites of RES, i.e. resveratrol-3-sulfate (R3S) and resveratrol-4'-sulfate (R4'S) in mouse model by both systemic and oral routes. In vitro studies were also conducted to test the desulfation in liver. Although we did not observe any significant RES in plasma, we observed from our in vitro studies that sulfated metabolites were desulfated in liver. Chapter 5 explains the detailed pharmacokinetics of glucuronidated metabolites of RES i.e. resveratrol-3-glucuornide (R3G) after both systemic and oral route. R3G was observed to undergo enterohepatic circulation. Explanation of R3G disposition in hepatocytes and enterocytes were proposed based on our own and reported results. In Chapter 6 we compared the differences in the kinetics of preformed versus in vivo formed metabolites using modeling and simulation approach. Individual models for disposition of RES, R3S and R3G were developed. These models were combined to give a global model for RES metabolism into R3S and R3G. Simulations were performed under two assumptions; preformed versus in vivo formed metabolite kinetics a) are same and b) they are not same. Our results reported that preformed and in vivo formed metabolite kinetics are not same at least for hydrophilic phase II metabolites. Chapter 7 includes method development and validation for quantitation of TMS in plasma and brain of mouse. Chapter 8 includes a steady state study to characterize the pharmacokinetic parameters of TMS, which was used to evaluate brain permeability of TMS. In summary we developed a robust bioanalytical method for direct quantitation of RES and its metabolites, found the lung to be a major metabolizing organ for RES, delineated complex kinetics of conjugated metabolites of RES, and showed differences in preformed versus in vivo formed metabolite kinetics and better brain permeability of TMS.

In Intelligent Transport Systems (ITS), the unavailable Road Side Unit (RSU) becomes an increasing serious safety-related problem because of its important role in ITS. However, there is no existing method to solve this problem effectively and stably nowadays. To solve the unavailable RSU problem, a novel 2-tier integrated communication system is proposed in this thesis to address the issue of unavailable RSU in ITS. Compared to some other solutions proposed in the previous research works, which mostly focus on improving the system performance by adjusting parameters of vehicular ad-hoc network among vehicles, the proposed 2-tier communication network, called ITS-LEO Integrated System (ILIS), is composed of conventional ITS system and Low Earth Orbit (LEO) mobile satellite system (MSS), where the LEO MSS is utilized as the complementary network when the RSU is unavailable. Since the LEO MSS primary message will get affected when overflowing messages from ITS to LEO MSS, we prioritize LEO MSS primary message over the overflowed message to minimize the effect, which is based on that the emergency message (EMsg) is given higher priority over routine message (RMsg) to get access to the channel in ITS. To optimize the utility of network resource, two different overflowing mechanisms are proposed in ILIS to improve system efficiency under different traffic density. Furthermore, we propose a bandwidth reservation protection mechanism for ILIS to increase the ITS network performance. A real-time simulation program in C++ is developed to evaluate the performance of ILIS in terms of Packet Loss Rate (PLR) and Delay, and simulation results show that adding LEO MSS as a complementary network to ITS is an effective way to solve the problem of an unavailable RSU.
