Pełny tekst źródłaSaproxylophagous Insects are involved in the degradation of dead wood. Many species of this complex are endangered. We studied the ecology Osmoderma eremita, a saproxylophagous beetle that is becoming scarce and is a short dispersal species. We monitored its populations by capture-recapture and radio-tracking. Fight capacities were measured in laboratory. Our goal was to explain the distribution of the species in an agricultural landscape, to study its dispersal capacities and some demographic characteristics. The landscape openness, the density of microhabitats and the persistence of the habitats during several decades have an influence on the species occurence. Dispersal capacities were three times greater than those observed in nature. The capacities of females were related to their condition. Sex-ratio was biased depending on population and year. Sex is a factor which should take place in viability analyses which would enable to propose conservation measures for O. Eremita

Resumo: A geometria de distâncias é o estudo da geometria baseado no conceito de distância. Ela é útil em várias aplicações, onde os dados de entrada consistem de um conjunto incompleto de distâncias, e a saída é um conjunto de pontos no espaço euclidiano, que realiza as distâncias dadas. No Problema de Geometria de Distâncias (DGP), é dado um inteiro K > 0 e um grafo simples, não direcionado, G = (V,E,d), cujas arestas são ponderadas por uma função não negativa d. Queremos determinar se existe uma função (realização) que leva os vértices de V em coordenadas no espaço euclidiano K-dimensional, satisfazendo todas as restrições de distâncias dadas por d. Um DGPk (com K fixado) está fortemente relacionado a um outro tipo de problema, que trata dos possíveis completamentos de uma certa matriz de distâncias euclidianas. Este último pode ser visto, em um certo sentido, como o "dual do primeiro problema". Neste trabalho, exploramos essa dualidade com a finalidade de propor melhorias no método Branch-and-Prune aplicado a uma versão discreta do DGPk
Abstract: Distance Geometry is the study of geometry based on the concept of distance. It is useful in many applications where the input data consists of an incomplete set of distances, and the output is a set of points in some Euclidean space which realizes the given distances. In the Distance Geometry Problem (DGP), it is given an integer K > 0 and a simple undirected weighted graph G = (V,E,d), whose edges are weighted by a non-negative function d. We want to determine if there is a (realization) function that associates the vertices of V with coordinates of the K-dimensional Euclidean space satisfying all distance constraints given by d. A DGPk (with K fixed) is closely related to another type of problem, which treats the possible completions of a certain Euclidean distance matrix. In some sense, this is the "dual" of the first problem. We explore this duality in order to improve the Branch-and-Prune method applied to a discrete version of the DGPk

Resumo: Motivado por estudos em estruturas 3D de proteínas, biomoléculas imprescindíveis no estudo da vida, surgiu um problema chamado Discretizable Molecular Distance Geometry Problem (DMDGP) que provou ser NP-Difícil. Para resolvê-lo, existe um algoritmo da literatura, Branch & Prune (BP), que utiliza uma estratégia combinatória de exploração de uma árvore binária de soluções associada ao problema. Além disso, foram descobertas relações de simetria que permitem obter uma solução, a partir de outra, através de reflexões nos chamados vértices de simetria. Alguns pesquisadores passaram a realizar este trabalho em paralelo (ParallelBP), dividindo uma instância em sub-instâncias, resolvendo localmente com o BP (o que pode ser feito em duas direções) e unindo as sub-soluções com movimentos rígidos, com o intuito de determinar as soluções em menor tempo. Nossa proposta é fornecer uma estratégia Dividir-e-Conquistar para resolver o DMDGP, de modo a melhorar a abordagem em paralelo. Ela possui três estágios. Inicialmente, dividimos uma instância em sub-instâncias duas-a-duas sobrepostas através dos vértices de simetria. Depois, utiliza-se os chamados gaps para decidir a direção em que o BP deve fornecer a solução local. Por fim, utilizamos rotações baseadas na Álgebra de Quatérnios para combinar as sub-soluções em soluções factíveis
Abstract: Motived by studies in 3D structures of proteins, essential biomolecules for Life, arised a problem called Discretizable Molecular Distance Geometry Problem (DMDGP) which proved to be NP-Hard. Aiming to solve it, there is an algorithm in the literature, Branch & Prune (BP), which uses a combinatorial strategy of exploring a binary tree of solutions that is associated to the problem. Moreover, some symmetry relations have been discovered which allows the obtainance of one solution from the other one by means of reflections in the so-called symmetry vertices. Some researchers started to do this work using parallel computing (ParallelBP), dividing one instance into sub-instances, solving the problem locally with the BP (what can be done in two directions) and joining the sub-solutions with rigid movements, with the objective of determining the solutions in a smaller time. Our purpose, thus, is to provide a Divide-and-Conquer strategy to solve the DMDGP in order to improve the parallel version. It has three stages. Initially, the instance is divided into sub-instances two-by-two overlapping by means of the symmetry vertices. After, the so-called gaps are used to decide the direction that the BP ought to provide the local solution. Finally, we propose to use Quaternion Rotations to combine sub-solutions into feasible solutions

Pełny tekst źródłaINTRODUCTION: Prune belly syndrome (PBS) is charactherized by a triad of abdominal wall flaccidity, bilateral criptorchidism and urinary tract malformation, that includes a large-capacity bladder, with high detrusor compliance, low sensibility and contractility, associated to urachal diverticulum or fistula and elevated post void residual volumes. Some autors recommend clinical treatment, but others propose surgery correction, with urinary tract reconstruction, including reductive ureteroplasty and cystoplasty, orchidopexy and abdominoplasty. Even after surgery, some patients need intermittent catheterism. The detrusor innervation determines its function, mediated by neuroceptors at the neuromuscular junction. The a1 adrenoceptors are related to detrusor contractility and b3 to relaxation, and some conditions, like infravesical obstruction, lead to a1 adrenoceptor up-regulation. The objective of this work is to verify whether, in the detrusor from patients with PBS, there is altered nerve density, up or down-regulation of a1a, a1b, a1d and b3 adrenergic receptors and if there is an abnormal proportion between muscle and connective tissue. MATERIALS AND METHODS A retrospective case-control study was performed involving 14 detrusor specimens from patients with PBS, who underwent surgical treatment between 1985 an 2005 at University of São Paulo, Medical School Hospital. Two groups were taken as control: 13 bladder fragments from patients who underwent radical prostatectomy at Department of Urology of Mainz University, with normal urodynamic study prior to the surgery (GC1) and 5 bladder fragments from children submitted to autopsy at SVOC-USP, with no neurological or urinary tract malformation (GC2). Staining was performed using the van Gieson dye to analyse the proportion between muscle and connective tissue, and immunohistochemical reaction was employed, with polyclonal antibodies against S100 protein, as well as a1a, a1b, a1d and b3 adrenoceptors. Brown colour was considered as evidence of adrenoceptor cell expression. Five to ten digital images were captured on an optic microscope with a digital camera. These images were analysed with Adobe Photoshop CS2Ò software. The relative quantity of receptors was calculated and the statistic analysis was done with the Kruskal-Wallis and Mann-Whitney tests. RESULTS Mean age was 1.28 ± 1.14 year in PBS patients, and 64 ± 5.22 yrs. and 1.41 ± 1.11 yrs. in GC1 and GC2, respectively. The median proportion between muscle and connective tissue was 1.08 in PBS, 1.59 in GC1 and in GC2 of 1.28 (p=0.173). The median proportion of S100/muscle area was 0.21 in PBS, 0.20 in GC1 and in GC2 of 0.01 (p=0.003). The median relative quantity of receptors of a1a was 0.06 in PBS, 0.16 in GC1 and 0.14 in GC2 (p=0.026). In a1b, the median values were 0.06 in PBS group, 0.006 in GC1 and 0.007 in GC2 (p=0.781). In a1d, the median values were 0.04 (PBS), 0.04 (GC1) and 0.05 (GC2) (p=0.618). Regarding b3, the median values were 0.07 in PBS, 0.14 in GC1 and 0.10 in GC2 (p=0.378). CONCLUSION Comparing detrusor fragments from patients with PBS and normal bladders, there was no alteration in the density of nerve endings. We observed downregulation of a1a adrenoceptors, but no alteration in the a1b, a1d and b3 receptors. Furthermore, there was no alteration of the proportion between muscle and connective tissue areas. Further investigations, with different methods and including other receptors, are necessary to transfer this knowledge to clinical use.

Pełny tekst źródłaStructural biology has allowed us expand our knowledge of living organisms. It is defined as the investigation of the structure and function of biological systems at the molecular level. Studying a biomolecule's structure offers insight into its geometry, as angles and distances between the biomolecule's atoms are measured in order to determine the biomolecular structure. The values of these geometrical parameters may be obtained from biophysical techniques, such as X-ray crystallography or nuclear magnetic resonance (NMR) spectroscopy. One of the most used methods to calculate protein structures from geometric restraints is simulated annealing. This method does not guarantee an exhaustive sampling of protein conformational space, which is a shortcoming as one protein may adopt multiple functional conformations, and it is important to determine them exhaustively. In this PhD project, the efficiency of a new method - derived from operations research and computational geometry - is studied in order to answer this question: How does this method explore the conformational spaces of small proteins? This method - implemented within the iBPprot software framework - treats protein structure determination as a distance geometry problem, which the interval branch-and-prune algorithm tries to solve by the full exploration of its solutions space. The results obtained by iBPprot on a set of test proteins, with sizes ranging from 24 to 120 residues and with known structures, are analyzed here. Using short-range exact distance restraints, it was possible to rebuild the structure of all protein targets, and for many of them it was possible to exhaustively explore their conformational spaces. In practice, it is not always possible to obtain exact distance restraints from experiments. Therefore, this method was then tested with interval data restraints. In these cases, iBPprot permitted the sampling of the positions of more than 70% of the atoms constituting the protein backbone for most of the targets. Furthermore, conformations whose r.m.s. deviations closer than 6 Angstrom to the target ones were obtained during the conformational space exploration. The quality of the generated structures was satisfactory with respect to Ramachandran plots, but needs improvement because of the presence of steric clashes in some conformers. The runtime for most performed calculations was competitive with existing structure determination method

Pełny tekst źródłaOne of the existing data mining techniques is association rules, responsible for identifying relationships that occur in the data set. Although the association rule is one of the most widely used techniques, the amount of extracted patterns can overload the user in such a way that finding interesting patterns among the large amount of obtained patterns becomes a challenge. To solve this problem, a large part of the association-related work is focused on the post-processing step. These works generally propose a post-processing approaches that, according to a certain strategy, aims facilitating the search for interesting patterns. Nowadays, approaches have included the user knowledge in the domain and / or interests on the process. However, in the current existing approaches, the user knowledge and/or interest must be explicitly described by some formalism, requiring a considerable time and may even lead to incomplete and / or incorrect specifications. In addition, the user has no idea what probably is interesting or which patterns to begin the searching. Notice that one of the challenges of these approaches is to consider the knowledge and / or user interest. In addition, consider the number of rules the user will examine is necessary. The analysis of the rules by an expert is expensive and, in most cases, the user wants to explore the rules generated without limiting exploration to the knowledge he already has. Therefore, the user evaluate the fewest amount of rules possible is important and, based on this assessment, the post-processing approaches be able to assist in the search for the rules that he may consider interesting. So, in this work is proposed that the post-processing is treated as a transductive semi supervised classification problem, since it allows the user to label some rules based on two predefined classes (e.g. \"interesting\"or \"not interesting\"), in a way that just a small amount of the rule set needs to be explored and all other association rules are automatically labeled. Furthermore, you can implicitly capture the knowledge and / or user interest in the domain by labeling some rules. Thus, the rules need to be modeled to allow: (a) select the rules to be labeled by the user to implicitly capture their knowledge and / or interest; (b) propagate the rules\' labels classified by the user to all not labeled rules. To do so, the rules were modeled via networks in this work, due to: (i) a large amount of network measures can be used in conjunction with the information provided by the user, to make item (a) possible; (ii) label propagation algorithms can be used in order to make item (b) possible. Therefore, we highlight that the contributions of this work are the ability to extract knowledge and / or user interest according to database characteristics and direct the user exploration without previously defining what will be explored. In addition, the results demonstrate that the proposed approach is able to direct the user to the knowledge considered interesting, reducing the amount of rules to be explored. Finally, this work also contributes to demonstrate that treat the post-processing of association rules as a problem of propagation of labels is possible.

Pełny tekst źródłaTwo experiments were conducted in greenhouse in order to evaluate the influence of plants spacing, the training systems and the height of pruning of main stem of mini watermelon through vertical conduction. The hybrid used was \'Smile\'. The experimental design was randomized blocks with four replications. The first experiment was carried out from August 12 to November 25, 2008. The treatments were three heights of pruning of main stem (1.7, 2.2 and 2.7 m) and two plants spacing (30 and 45 cm). The second experiment was carried out from October 20, 2008 to January 16, 2009 and the treatments consist of three training systems (S1 = one stem and one fruit per plant fixed in the main stem, S2 = one stem and one fruit plant fixed in the lateral branch and S3 = two stems and one fruit per plant fixed in the main stem) and two plants spacing (30 and 60 cm). In the first experiment the leaf area index, the content of soluble solids content (SS), ascorbic acid, acidity titratable (AT) and marketable yield were higher in 30 cm plants spacing. The total yield was influenced both the height of pruning and the plants spacing, whose greatest value was obtained by the combination of height of pruning of 2.7 m and spacing of 30 cm. However, the highest value for the ratio SS/AT was observed in the pruning of 2.2 m, and spacing of 45 cm. The height of pruning of 1.7 m provided the greatest percentage of fruit harvested in the last harvest. In the second experiment, the training system S2 with spacing of 30 cm between plants provided higher leaf area index and firmness of flesh. The total yield was higher in the training system S3 only than the training system S1. The training systems S1 and S3 promoted higher percentage of fruit harvested in the first harvest, while the system S2 the majority of fruits were harvested at last. Thus, taking into account the characteristics evaluated, in general, in the first experiment, the better option for the producer is the performance of pruning to 2.2 m in height and 30 cm plants spacing. In the second experiment, the conduction with two stems and one fruit (S3) with spacing of 30 cm between plants, and as a simple training system, provide high productivity and quality of fruit.

The objective of the present work was to determine the technical parameters for the compaction and the quality of the pellets produced from different types of forest biomass and residual agricultural biomass. The choice of the types of biomass was based on the production volume of the main agricultural and forestry crops of the State of Santa Catarina, and the economic, social and environmental importsnce of the same for the segments that produce them. In this way, the physical, chemical and energetic properties of four types of agricultural and forest residual biomass (Pinus chip, apple pruning branches, pinyon faults and araucaria grimpa) were used to produce the pellets. Thirteen treatments in the study were analyzed, consisting of pellets produced with: 100% pinus (P100), considered as a control treatment; 75% pinus and 25% of one of the analyzed residues (F25P75, when the residue was pinion failure, G25P75, for the treatment containing grimpa, and Pm25P75, when the treatment had apple pruning); 50% of pine and 50% of other analyzed components, being F50P50 (for pinion failure), G50P50 (grimpa) and Pm50P50 (apple pruning); (F100P25), G75P25 (Grimpa) and Pm75P25 (apple pruning) and the homogeneous treatments with 100% of failure (F100); 100% grimpa (G100) and 100% apple pruning (Pm100). For each treatment was established for the ideal parameters of temperature, pressure and compaction of the pellets produced in laboratory pelletizer. These data were established based on the physical and chemical properties of biomasses in nature and also on the quality of the non-process obtained pellet by means of successive compaction tests. After production of the pellets a quality of this biofuel was determined by its physical, mechanical, chemical and energetic properties. From the results obtained in the laboratory, pellets were classified based on the quality criteria of ISO 17225-2 for biomass pellets for energy generation. It was concluded that the treatments F75P25, G75P25 G50P50 and G25P75 were the only ones that reached quality for residential and commercial use. The treatment with better quality for residential and commercial use was treatment G25P75. The treatments Pm100, Pm75P25, Pm50P50, Pm25P75 and G100 did not achieve average ratings in relation to ISO 17225-2 for any quality category described in the standard
O objetivo do presente trabalho foi determinar os parâmetros técnicos para a compactação e a qualidade dos pellets produzidos a partir de diferentes tipos de biomassa florestal e agrícola residual. A escolha dos tipos de biomassa foi baseada no volume de produção dos resíduos das principais culturas agrícolas e florestais do Estado de Santa Catarina, e da importância econômica, social e ambiental dos mesmos para os segmentos que os produzem. Desta forma, foram caracterizadas as propriedades físicas, químicas e energéticas de quatro tipos de biomassas residuais agrícolas e florestais (maravalha de pinus, galhos de poda de macieira; falhas de pinhão; grimpa de araucária) que foram utilizadas para a produção dos pellets. Foram analisados 13 tratamentos no estudo, que consistiram de pellets produzidos com: 100% de pinus (P100), considerado como tratamento testemunha; 75% de pinus e 25% de um dos resíduos analisados (F25P75, quando o resíduo era a falha de pinhão, G25P75, para o tratamento contendo grimpa, e Pm25P75, quando o tratamento possuía poda de maça); 50% de pinus e 50% de outro componente analisado, sendo F50P50 (para falha de pinhão), G50P50 (grimpa) e Pm50P50 (poda de maça); misturas contendo 25% de pinus e 75% do outro resíduo analisado, sendo F75P25 (falha de pinhão), G75P25 (grimpa) e Pm75P25 (poda de maça) e os tratamentos homogêneos com 100% de falha (F100); 100% de grimpa (G100) e 100% de poda de maça (Pm100). Para cada tratamento foram estabelecidos os parâmetros ideais de temperatura, pressão e velocidade de compactação dos pellets produzidos em peletizadora piloto de laboratório. Estes parâmetros foram estabelecidos com base nas propriedades físicas e químicas das biomassas in natura, e também em função da qualidade do pellet obtido no processo, por meio de testes de compactação sucessivos. Após a produção dos pellets foi determinada a qualidade deste biocombustível por meio de suas propriedades físicas, mecânicas, químicas e energéticas. A partir dos resultados obtidos em laboratório, os pellets foram classificados com base nos critérios de qualidade da norma ISO 17225-2 para pellets de biomassa para geração de energia. Concluiu-se que os tratamentos F75P25, G75P25 G50P50 e G25P75 foram os únicos que atingiram qualidade para uso residencial e comercial. O tratamento com melhor qualidade para uso residencial e comercial foi o tratamento G25P75. Os tratamentos Pm100, Pm75P25, Pm50P50, Pm25P75 e G100 não conseguiram classificações médias em relação a ISO 17225-2 para nenhuma categoria de qualidade descrita na norma

In practice, it is not always possible to obtain exact distance restraints from experiments. Therefore, this method was then tested with interval data restraints. In these cases, iBPprot permitted the sampling of the positions of more than 70% of the atoms constituting the protein backbone for most of the targets. Furthermore, conformations whose r.m.s. deviations closer than 6 Angstrom to the target ones were obtained during the conformational space exploration. The quality of the generated structures was satisfactory with respect to Ramachandran plots, but needs improvement because of the presence of steric clashes in some conformers. The runtime for most performed calculations was competitive with existing structure determination method

Pełny tekst źródłaEls assajos en localitats múltiplas de poblacions de mapeo s'utilitzen freqüentment per a testar genotips en un conjunt d'ambients representatius de la condicions climàtiques on es volen introduir aquests genotips. La primera part d'això treball ha estat l'avaluació de la població de mapeo ‘Nure x Tremois’ constituïda de 118 de doble haploides d'ordi, juntament amb panell d'associació que comprèn 185 varietats d'ordi representatives del germoplasma conreat en la conca Mediterrània. El material vegetal ha estat assajat en una combinació de divuit camps per any desllorigats en sis països de la conca mediterrània. Els assajos s'han portat a terme en camps amb diferent disponibilitat d'aigua, classificats sobre la base de les dades relatives a les freqüència i quantitat de les precipitacions o en el mateix lloc amb un camp en secà i altre regat. Els assajos es van portar a terme per dos anys en cada localitat i això va permetre la recollida d'un gran volum de dades que comprenen caràcters agronómicos relacionats amb rendiment i components del rendiment, dades fenológicos i ambientals. Aquestes dades es van utilitzar després per a la identificació de regions genomicas involucrades en l'adaptació de l'ordi a l'ambient. Els 118 dobles haploides de la població ‘Nure x Tremois’ es genotiparon amb marcadors DaRT (Diversity Array Technology), després un set de 15 marcadors CAPS I SCCP per a gens candidats involucrats en la regulació de les fases fenológicas van ser afegits al mapa de lligament construït amb els marcadors DaRT. Les dades van ser utilitzats per a fer una anàlisi de QTL amb procediment ‘Composite Interval Mapping’ para cada combinació ambienti/ caràcter. Es van trobar diversos QTLs per rendiment i data d'espigolat i components del rendiment. Els QTL mes freqüents trobats per rendiment i data de floració i components del rendiment estan localitzats en els cromosomes 1H (3 camps), 2H (8 camps) i 5H (5 camps) coincidents respectivament amb HvFT3 locus, eam6/Eps-‐2 (earliness per se) locus i amb el locus de vernalización Vrn-‐H1. Una ulterior anàlisi de QTL feta amb el mètode “Multi Environment Trial” ha revelat que els QTL localitzats en el locus eam6/Eps-‐2 (cromosoma 2H) i Vrn-‐H1 (cromosoma 5H) són comunes per rendiment i data de floració en els 18 camps d'assaig. Per això utilitzem tots el dades ambientals col·leccionades durant tot el cicle del cultiu per a investigar la sensibilitat de dites QTL a les co-‐variables ambientals. La majoria de les associacions oposades estan relacionades amb temperatures i variables relacionades amb aquestes. Eam6/Eps-‐2 mostra una interacció de tipus quantitatiu amb aquestes variables mentre Vrn-‐H1 mostra una interacció de tipus qualitatiu amb aquestes variables. Les 185 varietats assajades van ser genotipadas amb 185 SNPs i fenotipadas per resistència a fred en dos assajos uneixo a Espanya i altre a Itàlia. El primer assaig va ser caracteritzat per un hivern excepcionalment fred, mentre el d'Itàlia ha estat utilitzat en passat per testar resistència a fred a causa de els hiverns rígids que solen registrar-‐se en aquesta localitat. Les dades van ser utilitzats per a portar a terme la analisis GWAS “Genome Wide Association Analysis” . Els resultats van permetre identificar 13 regions genomicas involucrades en la resistència a frio. Entre elles tres regions coincideixen amb loci ja mapeados i coneguts per ser involucrats en la resposta a frio en los cromosomes 2HL, 4HL i 5HL.

Exploratory testing is a software testing approach that emphasizes the tester’s experience in the attempt to maximize the chances to find bugs and minimize the time effort applied on satisfying such a goal. It is naturally a GUI-oriented testing activity for GUI-based systems. However, inmost cases,exploratory testing strategies may not be accurate enough to reach changed code regions. To reduce this gap, in this work, we propose a way of aiding exploratory testing by providing a GUI model of the regions impacted by internal code changes (for example, as result of change requests to fix previous bugs as well as for software improvement). We create such a delimited GUI model by pruning an original GUI model, quickly built by static analysis, using a reachability relation between GUI elements (i.e., windows, buttons, text fields, etc.) and internal source code changes (classes and methods). To illustrate the idea we provide promising data from two experiments, one from the literature and another from our industrial partner.
Teste exploratório é uma abordagem de teste de software que enfatiza a experiência do testador na tentativa de maximizar as chances de encontrarbugs e minimizar o esforço de tempo aplicado na satisfação desse objetivo. É naturalmente uma atividade de testes orientada à GUI aplicada em sistemas que dispõem de GUI. No entanto, na maioria dos casos, as estratégias de testes exploratórios podem não ser suficientemente precisas para alcançar as regiões de código alteradas. Para reduzir esta lacuna, neste trabalho nós propomos uma forma de auxiliar os testes exploratórios, fornecendo um modelo de GUI das regiões impactadas pelas mudanças internas de código (por exemplo, como resultado de solicitações de mudanças para corrigirbugs anteriores, bem como, para realização de melhorias do software). Criamos um modelo de GUI delimitado, podando um modelo de GUI original, construído rapidamente através de análise estática, usando uma relação de alcançabilidade entre elementos de GUI (janelas, botões, campos de textos) e alterações de código interno (classes e métodos). Para ilustrar a ideia, nós fornecemos dados promissores de dois experimentos, um da literatura e outro de nosso parceiro industrial.

Pełny tekst źródłaOur thesis studies the blames directed by the philosopher and sophist Dio of Prusa at the cities in the whole of his discourses. We show how Dio, thinking his duty to commit himself in politics, uses a skilful way to blame the immoral cities. We define the dionean idea of the city (an idealtype of the polis). The first part of our works (" Dio and the tradition of the blame to the city ") surveys the models of the past Dio uses in order to blame. The second part defines " the principles of the blame " : the power to rebuke of the Emperor and of the notables ; then we show Dio's friends and enemies, the circles and the clans. We see how many are the terms Dio uses to signify reproach ; at last, the values for which the philosopher blames the cities. In the third part (" the rebukes and their efficacy "), we list the different topoi for the blame to the city. Then are investigated the rebukes in several fields : in politics, in economy, in social life and in ethics. Finally, we assess the real efficacy of the dionean blame

Pełny tekst źródłaThe aim of this work is to show how dio's attitude as a writer has been influenced by his point of view on the greek culture and the way the latter has to be used in ancient oratory. It led him to look for elaborate stategies in literature. Dio's thoughts about the problem of education and culture in the greek world, during the 1rst century a. D. , are being analysed here : he sets himself to assess and change if necessary contemporary facts, from the point of view of a moralist. His references are the classical literature. The purpose of the second part is to explain how dio used the elements offered by the greek paideia in oral communication. The uses with great liberty a type of speech very near to the sophistic lalia, and therefore, sets himself apart from the other speakers. For his main purpose in the oratory activity is the moral edification. According to his definition of philosophical eloquence wich seeks a upheaval of the soul, literary devices must be very close to that commonly used in the attractive speeches of the sophists. Meticulous pictures, narratives and dialogues are profusely used by dio. They allow a clear representation of mankind's moral attitudes and upper feelings. However, dio seems to prefer the narration, myth, tale or anecdote. With the narration, he can also express his ideas and feelings in a better way. Then literary memories and genres are mixed, and they contribute to relating some experiences in which the search of cultural and personal truth integrate the novelist's te

Pełny tekst źródłaThere are many types of membrane lipids throughout Nature. Still little is known about synthesizing pathways and how different lipids affect the embedded membrane proteins. The most common lipids are glycolipids since they dominate plant green tissue. Glycolipids also exist in mammal cells as well as in most Gram-positive bacteria. Glycosyltransferases (GTs) catalyze the final enzymatic steps for these glycolipids. In the bacteria Acholeplasma laidlawii and Streptococcus pneumonie and in the plant Arabidopsis thaliana, GTs for mono-/di-glycosyl-diacylglycerol (-DAG) are suggested to be regulated to keep a certain membrane curvature close to a bilayer/nonbilayer phase transition. The monoglycosylDAGs are nonbilayer-prone with small headgroups, hence by themselves they will not form bilayer structures.
Here we have determined the genes encoding the main glycolipids of A. laidlawii and S. pneumonie. We have also shown that these GTs belong to a large enzyme group widely spread in Nature, and that all four enzymes are differently regulated by membrane lipids. The importance of different lipid properties were traced in a lipid mutant of Escherichia coli lacking the major (75 %), nonbilayer-prone/zwitterionic, lipid phosphatidylethanolamine. Introducing the genes for the GTs of A. laidlawii and two analogous genes from A. thaliana yielded new strains containing 50 percent of glyco-DAG lipids. The monoglyco-DAG strains contain significant amounts of nonbilayer-prone lipids while the diglyco-DAG strains contain no such lipids. Comparing these new strains for viability and the state of membrane-associated functions made it possible to connect different functions to certain lipid properties. In summary, a low surface charge density of anionic lipids is important in E.coli membranes, but this fails to be supportive if the diluting species have a too large headgroup. This indicates that a certain magnitude of the curvature stress is crucial for the membrane bilayer in vivo.

Pełny tekst źródłaThe two topics covered in this work are strictly correlated to the professional experiences. Particularly, I spent the first period at the University of Milan-Bicocca in the preclinical ICU laboratory directed by Prof. Giacomo Bellani, where my work has been focused on the diaphragm dysfunction during a mechanical ventilation (VIDD); in particular, in the effectiveness study of a therapeutical treatment with Angiotensin-(1-7) in a rat model of VIDD. In the second part of my PhD course, I had a chance to rotate at the University of Pennsylvania to conduct a similar research but in the progression of lung injury. In the anesthesia laboratory of Prof. Maurizio Cereda, the main purpose has been investigating and evaluating the effects of pronation in a large model of ARDS. Diaphragmatic dysfunction and pulmonary stress during mechanical ventilation are serious conditions that reducing positive outcomes and weaning successful in ICU patients. Ventilator-induced diaphragmatic dysfunction (VIDD) is a common event during mechanical ventilation (MV) leading to rapid muscular atrophy and contractile dysfunction. The first study in my thesis was designed to evaluate the effects of the treatment with Ang-(1-7) in a rat model of VIDD. MV resulted in a significant reduction of diaphragmatic contractility in all groups of treatment. Ang-(1-7)-treated rats showed higher muscular fibers cross sectional area and lower Atrogin-1 and Myogenin mRNA levels, compared to Vehicle treatment. Treatment with the antagonists of Mas and AT2R caused a significant reduction of muscular contractility and an increase of Atrogin-1 and MuRF-1 mRNA levels, not affecting the cross sectional fiber area and Myogenin mRNA levels. Systemic Ang-(1-7) administration during MV exerts a protective role on the muscular fibers of the diaphragm preserving muscular fibers anatomy and reducing atrophy. The involvement of Mas and AT2R in the mechanism of action of Ang-(1-7) still remains controversial. It is not known how lung injury progression during mechanical ventilation modifies pulmonary responses to prone positioning. The aim of the second work of my thesis was compared the efficacy of prone positioning on regional lung aeration in late vs. early stages of lung injury using a pig model of ARDS. The main findings reported that gas exchange and respiratory mechanics worsened over 24 hours, indicating ventilator-induced injury progression. On Day 1, prone positioning reinflated 18.9 ± 5.2% of lung mass in the posterior-caudal lung regions. On Day 2, position-associated dorsal reinflation was reduced to 7.3 ± 1.5% (P<0.05). Prone positioning decreased aeration in the anterior lungs on both days. In the early ARDS patients, prone positioning improved posterior lung compliance, but it had no effect in late ARDS subjects. Overall, the effects of prone positioning on lung aeration may depend on the stage of lung injury and duration of ventilation; this may limit the clinical efficacy of this treatment if applied late.
