A cultura do tomateiro (Solanum lycopersicum L.) é importante mundialmente devido ao alto consumo de seus frutos. Nos últimos anos surgiram nesta cultura no Brasil alguns vírus emergentes com altas taxas de disseminação, como begomovírus e crinivírus, transmitidos pela Bemisia tabaci biótipo B, que podem causar danos à produção do tomateiro. A espécie de begomovírus atualmente mais encontrada no Brasil, em plantios de tomateiro, é o Tomato severe rugose virus (ToSRV). De 2002 a 2004, pesquisadores relataram incidências desse vírus em mais da metade das amostras com sintomas de geminiviroses coletadas em vários estados brasileiros e sua presença continua sendo verificada frequentemente. No ano de 2006, um crinivírus, o Tomato chlorosis virus (ToCV), foi relatado no Brasil, infectando plantas de tomate no Estado de São Paulo e atualmente encontra-se presente em diveros estados brasileiros. Os objetivos desse trabalho foram: determinar os períodos mínimos de acesso à aquisição e à inoculação do ToSRV e do ToCV pela B. tabaci biótipo B; identificar o período de retenção do ToSRV no inseto e a interação do ToSRV e do ToCV na aquisição e na transmissão por esse aleirodídeo. Também foi avaliada a eficiência do inseticida cloridrato de cartape no controle da disseminação primária e secundária do ToSRV pela B. tabaci biótipo B em tomateiros em gaiolas em casa de vegetação. Finalmente avaliou-se a eficiência do aleirodídeo Trialeurodes vaporariorum na transmissão de um isolado brasileiro do ToCV. Os períodos mínimos de acesso à aquisição e à inoculação de ambos os vírus pela B. tabaci biótipo B foram de cinco minutos. O tempo de retenção do ToSRV em B. tabaci biótipo B foi de 25 dias. A eficiência de um único adulto de B. tabaci na transmissão simultânea do ToSRV e do ToCV para tomateiros foi de 44,7%, similar àquela da transmissão isolada do ToRSV (47,4%) e do ToCV (44,7%). A eficiência de T. vaporariorum na transmissão do ToCV foi inferior à da B. tabaci biótipo B. Usando 40 insetos por vaso com duas plantas as eficiências de transmissão foram 57,7% e 100%, respectivamente. O inseticida cloridrato de cartape reduziu a infecção secundária do ToSRV pela B. tabaci biótipo B, mas não foi eficiente para reduzir a infecção primária em tomateiros.Tomato (Solanum lycopersicum) is one of the leading vegetables grown and consumed in Brazil and in the world, after potato. The importance of tomato is related to its high consumption worldwide and also its nutritive value. Presently the most important virus diseases responsible for yield losses on tomato crops in Brazil are those caused by begomovirus and crinivirus, both transmitted by Bemisia tabaci biotype B. At the moment the prevalent species of begomovirus is Tomato severe rugose virus (ToSRV). From 2002 to 2004, researchers reported incidence of this virus in more than half of the symptomatic tomato samples collected in several Brazilian states. In 2006, a crinivirus, Tomato chlorosis virus (ToCV), was reported for the first time in Brazil, infecting tomato plants in the State of São Paulo and at present the virus occurs in several Brazilian states. The objectives of this study were to determine the minimum acquisition and inoculation access periods of ToSRV and ToCV by B. tabaci biotype B; identify the retention period of ToSRV in the insect; and the interaction of ToSRV and ToCV on the transmission by this aleyrodidae. It was also evaluated the effectiveness of the insecticide cartap hydrochloride in controlling the primary and secondary spread of ToSRV by B. tabaci biotype B on tomato plants in a greenhouse. Finally, it was evaluated the efficiency of Trialeurodes vaporariorum in the transmission of a Brazilian isolate of ToCV. The minimum acquisition and inoculation access periods for both viruses by B. tabaci biotype B were five minutes. The maximum retention time of ToSRV in B. tabaci biotype B was 25 days. The efficiency of a single adult of B. tabaci to simultaneously transmit ToSRV and ToCV to tomato plants was 44.7%, similar to the transmission of ToRSV (47.4%), and ToCV (44.7%) separately. T. vaporariorum was less efficient than B. tabaci on the transmission of ToCV. Using 40 insects per pot with two plants, transmission efficiencies were 57.7% and 100%, respectively. The insecticide cartap hydrochloride reduced secondary infection of ToSRV transmitted by B. tabaci biotype B, but was not effective in reducing the primary infection in tomato.

Barcelona – Highschool Barcelona – Vallcarca Vallcarca is a city district with very special character, rugged topography, heterogenous social structure and two different scales of constructions. It is also an important pedestrian connection between park Güell and other city parks. Soon, its probable, that considerable changes will happen here. Except the highschool, the objective was to create on our land a quality public space for students and also for Vallcarca and if possible to reuse the building of the old school. The public square is surrounded by highschool building, used by Vallcarca inhabitants. New public passage between two levels is planned, for better connection between Güell and other parks. The hisgh school is planned as four pavillions with different height, connected between them by private courtyards or public street. Students animate the public space, walking among the school functions. The principal entrance is against the old school building, its an open-air vestibule, coverred by pergola. The height of pavillions reacts on the landscape and the scale of surrounding buildings. Inside, the pavillions are composed of two tracts – the classes and the gallery. Every pavillion has two stairs and the gallery is in contact with the courtyard. At the ends of gallerie are student loggias, used as entertainment space. The same purpose has the hall in the ancient stone mine. On the other side of the street, the old school building is used as restaurant, with its facilities in the new extension. The public space is limited on the south side by new construction of the library.

Full textAbstract:
B+B Barcelona/master’s thesis/Iva Křikavová/studio of Ivan Koleček/2010 Urban Plan of Poble Nou district of Barcelona in the past was strongly defined, factory halls fully built the block, streets and squares had a clear structure. Industry terminated operations and adjacent diagonals became attractive for various companies, hotels and developers, who started to build. Thirty-storey houses with undefined environment, the structure is lost, chaos prevails. To preserve the character of the plan, the old and the newly formed buildings, became a clear definition of the school block. Definition of block one hundred years ago lay in the absolute middle of the courtyard, but how to behave now in 2010? The answer is to define a block with three houses, each of then has its function - school, sports, library and dining room. Among them are moving teachers and students, experiencing the way, change the focus away leaving behind the school building and coming to do sports, eat or read a book. Actual volumes, however, could not become the answers, they could not become to be an integrated bloc. The space between them must band them together to give a complete character, followed by the part-built and connect everything to each other, gain mobility system common to all three. The solution became a principle belts - belt bound outdoors, belt inner freedom (hall, path to the target classroom, a room) and the target belt in the form of classrooms, gym and multipurpose halls. Cerda Plan for unique compared to other rectangular nets are the squares that are created with cutting off corner of the block. Project in such an urban network should respond to this. What is the city block and cut off the corner? In a project for me is not a barrier to good regular layout, but instead of entering the city and its principles into the project and school responses to these special places. In all four corners is resulting in an open hall houses all over the floor, becoming an indoor view schools in cities and towns for school. The system is one exception, it is an existing church, which has not an ambitions to become something special and unusual, but is part of the whole. Each object has its own ledge. This has become a symbol of an element that turns the house imide to the courtyard and other buildings. It connects the building and the downstream area, it gives him character building, sport connects with an outdoor playground, building a library with a place for rest and home school with a place with trees. All three ledges are the same height, thus uniting the whole school, the whole block. Facades are open underneath, glazed, thus having a different character than the rest.

Full textAbstract:
Xanthan is a polysaccharide widely used in food, cosmetics, and enhanced oil recovery (EOR) by polymer flooding. In polymer flooding addition of polymers increases the viscosity of the injection water used for oil extraction from the oil producing wells. It is desirable to take advantage of biopolymers in EOR, due to their biodegradability and easily accessible raw materials of low costs. By hydrophobically modifying xanthan the thickening properties may be improved, due to intra- and intermolecular interactions between hydrophobic side groups. In this master thesis xanthan was hydrophobically modified by grafting of octylamine using carbodiimide chemistry, applying a method adopted from the University of Le Havre, France. Properties of non-modified and modified xanthan samples prepared from two different start xanthans, from Kelco and Statoil, were studied by SEC-MALLS, intrinsic viscosity measurements, and 1H-NMR spectroscopy. In order to obtain xanthan molecules of a size suitable for these analysis methods, sonication was performed. Xanthan samples were sonicated for different times, and an obvious decreasing trend of the molecular weight and intrinsic viscosity as the sonication time increased was shown. Intrinsic viscosity dependence on molecular weight was in good accordance to previous reported results.Depolymerisation by H2O2 and NaOH prior to 1H-NMR analysis did not have the desirable effect on degradation of xanthan chains. The side groups were cut off, rather than breaking the β-1,4 bonds between the glucose units in the xanthan backbone. By comparing the grafting density of octylamine for an acetyl and pyruvyl free xanthan sample and xanthan samples with these groups intact, it was shown for the first time that more than half of the octylamine binds to the carboxylic acid of the pyruvyl group on the β-D-mannose of xanthan. Intrinsic viscosity determined by a single capillary viscometer was higher for modified xanthan than non-modified, while by a four-bulb shear dilution viscometer the opposite was shown. The intrinsic viscosity was shown to be dependent on shear rate by the four-bulb viscometer, and the intrinsic viscosities at zero shear for non-modified and modified xanthan was significantly higher than that determined by single capillary viscometer.

Full textAbstract:
Le génome des Babesia, hémoprotozoaires parasites du phylum des Apicomplexa, étant largement méconnu, nous avons effectué une approche chromosomique par PFGE, suivie d'expériences d'hybridation moléculaire du génome de l'espèce canine B. Canis mondialement répandue, de l'espèce bovine européenne B. Divergens et de l'espèce murine B. Microti (Theileria microti), principal agent de la babéiose humaine aux U. S. A. . L'utilisation d'une sonde télomérique dérivée du génome de Plasmodium berghei et de sondes spécifiques du génome des espèces étudiées, a permis de déterminer la taille du génome, le nombre de chromosomes et d'analyser le polymorphisme caryotypique de chacune d'elles. Ainsi, l'étude du génome de B. Divergens, à travers 7 isolats des deux sous-espèces canines les plus pathogènes i. E. B. Canis canis (Europe) et B. Canis rossi (Afrique du sud), a mis en évidence 5 chromosomes pour un génome estimé à 14,5 Mpb et 16 Mpb, respectivement. Toutefois, l'analyse comparée de l'organisation télomérique possible et du contenu génique de ces deux sous-espèces a montré qu'il existait autant de différences entre celles-ci qu'entre chacune d'elles et l'espèce B. Divergens. Le génome de B. Microti estimé à 6,5 Mpb pour 4 chromosomes, apparaît quant à lui comme le plus petit génome de Babesia décrit. Enfin, cette analyse chromosomique a permis de démontrer que les gènes Bd37 sont localisés sur le chromosome 2 de B. Divergens, tandis que ceux de la famille Bc3. 1 seraient localisés sur les 5 chromosomes de B. Canis. L'analyse du polymorphisme des deux membres de la famille Bc3. 1 indique un polymorphisme important entre les extrémités 3' des deux copies et une grande conservation de ces deux copies entre isolats géographiquement distants.

Full textAbstract:
A b-coloring of G is a proper vertex coloring such that there is a vertex in each color class, which is adjacent to at least one vertex in every other color class. Such a vertex is called a color-dominating vertex. The b-chromatic number of G is the largest k such that there is a b-coloring of G by k colors.
Moreover, if for every integer k, between chromatic number and b-chromatic number, there exists a b-coloring of G by k colors, then G is b-continuous. Determining the b-chromatic number of a graph G and the decision whether the given graph G is b-continuous or not is NP-hard. Therefore, it is interesting to find new results on b-colorings and b-continuity for special graphs.
In this thesis, for several graph classes some exact values as well as bounds of the b-chromatic number were ascertained. Among all we considered graphs whose independence number, clique number, or minimum degree is close to its order as well as bipartite graphs. The investigation of bipartite graphs was based on considering of the so-called bicomplement which is used to determine the b-chromatic number of special bipartite graphs, in particular those whose bicomplement has a simple structure. Then we studied some graphs whose b-chromatic number is close to its t-degree.
At last, the b-continuity of some graphs is studied, for example, for graphs whose b-chromatic number was already established in this thesis. In particular, we could prove that Halin graphs are b-continuous.

Uno de los principales problemas que afecta la calidad de vida de los ciudadanos es el tráfico y congestión vehicular. Basados en dicha problemática, en el presente informe se investigará la situación actual y verificará la existencia de dicho problema en la ciudad de Lima, Perú. Asimismo, se propondrá una idea de negocio la cual, permitirá contrarrestar dicho mal. Para ello, se evaluaron posibles soluciones y se reconoció como medio alternativo de transporte a la bicicleta, como la micro movilidad más adecuada para atacar el obstáculo referido en nuestra ciudad. Principalmente, la propuesta de solución que se ofrece a lo largo del presente informe, es el alquiler de bicicletas pertenecientes a habitantes de Lima a quienes en adelante llamaremos Arrendadores, hacia terceros llamados Arrendatarios quienes pagarán y accederán a dichos transportes. Además, dicha transacción podrá realizarse a través de una plataforma (aplicación) que nosotros facilitaremos para poner en contacto a solicitantes de bicicletas con personas que quieren poner en alquiler la propia. A fin de validar y levantar información, se realizaron entrevistas y encuestas que validaron nuestras hipótesis. Asimismo, se fijó un precio tomando como referencia el precio base de las empresas competidoras. Finalmente, se realizaron tanto proyecciones financieras como el análisis de las mismas y finalmente, se comprobó la viabilidad, además, la rentabilidad del proyecto.One of the main problems affecting the quality of life of citizens is traffic and traffic jam.

In addition, this transaction would be carried out through a platform (application) that we will facilitate to contact bicycle applicants with people who want to rent their own. In order to validate and gather information, interviews and surveys were conducted that validated our hypotheses. Likewise, a price was set based on the base price of the competing companies. Finally, both financial projections and their analysis were made and finally, the viability was verified, in addition, the profitability of the project.

Full textAbstract:
Tesis para optar al título de Realizador en Cine y Televisión“LADO B” es un cortometraje de corte híbrido que entremezcla el registro documental con la ficción. Gonzalo Ortega (45) es un ficticio rockero ochentero que se ve obligado a volver a Chile, luego de estar casi una década viviendo en España, debido a la crisis. Tras su regreso se convierte en un allegado en la casa de su separada hermana Sofia (50), donde tiene que compartir el espacio de un pequeño departamento junto a ella y su hijo menor Javier (17), con quién comenzará a tener una relación de amistad en torno a la música, mientras vuelve a acostumbrarse a Santiago. Además junto a Mario, su antiguo manager, organizan el concierto que traerá de vuelta a Gonzalo a los escenarios, lo cual consideran es la última oportunidad de revivir la congelada carrera del músico y competir en la escena local. Esta situación llevará al personaje a reencontrarse con la vida familiar y adaptarse a la nueva escena musical. En paralelo a la historia de ficción, irá montado un material de archivo falso en el que una cámara documental seguirá a Gonzalo, conversará con él y nos adentrará en sus pensamientos y su mundo interior. Este cortometraje busca contar una historia sencilla, que mezcla rasgos de la vida cotidiana de Santiago junto con elementos de la cultura pop chilena, que acercarán al espectador y le darán verosimilitud a nuestro ficticio músico, además de entender como se mueve la ciudad y el mundo artístico en un país pequeño como Chile.

TESIS PARA OPTAR AL GRADO DE MAGÍSTER EN ADMINISTRACIÓNRicardo Enrique Cuevas Arriagada [Parte I], Neil William Páez Bustos [Parte II]
El presente trabajo desarrolla una idea de negocio llamada B-Trials, cuyo origen surge a partir de una necesidad específica en la ejecución de Estudios Clínicos de la Industria Farmacéutica local, que corresponde al aumento en la participación de pacientes en la ejecución de los protocolos de estudios, a modo de aumentar la competitividad frente a los otros países de la región. Actualmente, son los médicos tratantes, colegas y/o contactos de los mismos quienes derivan pacientes a los Estudios Clínicos, por lo que este proyecto plantea la creación de una nueva forma de captación de pacientes e implementar una nueva forma de derivación de pacientes, con el fin de revolucionar a este mercado de USD $30 MM anuales. Gracias a la fluidez de los procesos regulatorios y obtención de resultados requeridos por las compañías farmacéuticas, es que Chile se hace atractivo, sopesando la menor cantidad de pacientes que puede ofrecer a diferencia de países como Argentina, Brasil, Colombia y México. Dado que desde los inicios de la Investigación Clínica en Chile se ha utilizado el mismo sistema de derivación de pacientes, B-Trials toma esta oportunidad y captará pacientes en el mundo de las Redes Sociales, que cada vez son más utilizadas por la sociedad, los que serán registrados en una página web y se construirá una base de datos propia. La base de datos permitirá identificar a distintos pacientes dispuestos a participar en los Estudios Clínicos, de acuerdo a parámetros clínicos específicos y zonas geográficas donde se encuentran, permitiendo la derivación de estos a Centros de Estudios ya operativos y dando la opción de tener la información necesaria para la instalación de un Centro de Estudios Clínicos propio en la ubicación con mayor demanda de pacientes y abastecerlo de pacientes. El equipo gestor está encargados del marketing, operaciones y comercial, áreas cruciales para la obtención de la ventaja competitiva. El proyecto B-Trials requiere de una Inversión Inicial de CLP $67 MM., con Payback de 3,5 años, TIR = 31% y VAN al año 5 de CLP $ 23 MM. Valor Residual = $ 403 MM. Tasa de descuento aplicada = 20,4%. B-Trials representa un negocio que satisface una necesidad de la Industria en forma innovadora, siendo pionero en el país y escalable en el territorio nacional y latinoamericano, mejorando la calidad de vida de los pacientes a través del acceso gratuito a tratamientos de última generación.

Flavor oscillations of neutral B mesons have been studied with e+e- annihilation data collected at center of mass energies near the [gamma](4S) at the PEP-II asymmetric collider with the BABAR detector. One B⁰ is fully reconstructed in a hadronic decay to a flavor eigenstate. The flavor of the other B in the event is determined using an inclusive tagging algorithm which exploits the correlations between the flavor of the b quark and the charges of its decay products. By fitting the decay-time distribution of the observed mixed and unmixed final states, the oscillation frequency, [Delta]md, is determined to be 0.516 +/- 0.016 (stat.) +/- 0.010 (syst.) ps-l.

Full textAbstract:
A new set of urban design requirements is proposed to replace the current urban design guidelines for the B. C. Place site in Vancouver, B. C. The site is 90.6 hectares of open area, contiguous to the downtown, it is the subject of extensive planning activities. The site has been chosen because it is free of most of the typical impediments that constrain urban planning in more congested areas of the city. Accordingly, a new way of expressing urban space is appropriate.
To be valid urban design requirements must be conceived with a purpose in mind. The purpose, here, is the essential element of urban design, a shared vision of urban space. It must define, within a broad public consensus, a set of urban design requirements communicating, over an extended time period, a consistent vision of urban space.
Six urban design requirements are set out to implement a shared vision of urban space. They have been reduced to a minimum to provide as much freedom of expression to the design professions as possible. They are under six headings: Interim Land Use, Site Development, Physical Form and Design, Environment, Occupancy, and Movement.
Pivotal in the composition of the urban design requirements is an instrument called the Orthodox Surface Modulator, augmented by a Check List of architectural design elements. Together they become a metaphoric framework of reference, a part of the creative process within the development control system.
The Orthodox Surface Modulator, as it is applied, describes the volumetric forms of building envelopes and the public urban spaces between buildings. It describes buildings and spaces to enhance public amenity. It may, under specific environmental circumstances, mitigate undesirable site conditions by describing building envelopes as buffer buildings, shielding passive urban space from noise and distractions.
Urban Space is discussed. A Shared Vision of Urban Space, how it is evolved by public discourse, and a proposed Theory of Urban Space is explained. A critique of current urban development on Burrard Street, Vancouver, between Georgia Street and the waterfront explains why the present urban design guidelines, transfer of development rights and bonusing, have failed to produce the intended urban spatial amenity.
Urban design requirements are not a new phenomenon. Only since the early 1970s have they taken on their present complex form in the City of Vancouver. A brief historic outline traces the antecedents of the proposed urban design requirements, placing them in context from early Greek attempts to rationalize optical distortion to the present day.
The proposed application of the six urban design requirements and the Surface Modulator would be mandatory. The manner in which the elements of the Check List are integrated into the matrix of the Surface Modulator is proposed to be discretionary. The complete set of urban design requirements are intended to be used in a negotiating procedure common in planning practice.Applied Science, Faculty of

La ()-ebelactone b, molecule qui possede des proprietes immunostimmulantes, appartient a la famille des -lactones naturelles.

L'objectif de notre travail etait d'une part d'etudier la reactivite du trimethylsilylcetene dans les cycloadditions 2+2 sur des aldehydes chiraux et des imines pauvres en electrons, et d'autre part de realiser une approche synthetique de la ()-ebelactone b qui mettrait en jeu une reaction de cycloaddition 2+2 comme etape-cle. Ce manuscrit debute par une revue bibliographique des cycloadditions 2+2 catalysees par un acide de lewis, permettant d'acceder a des cyclobutanes ou a des heterocycles a 4 chainons. Il se poursuit par une mise a jour sur la preparation et la reactivite des -lactones, qui decrit les methodes nouvelles developpees depuis 1993 et leur application en synthese totale. La formation diastereoselective de -lactones par cycloaddition 2+2 entre le trimethylsilylcetene et des aldehydes chiraux - ou -substitues, en presence d'un acide de lewis a ete etudiee. Un mecanisme a ete propose pour le rearrangement parfois oberve des -lactones. La cycloaddition 2+2 catalysee par un acide de lewis entre le trimethylsilylcetene et une glyoxaldimine a conduit a la formation d'un -lactame silyle, pour laquelle nous proposons un mecanisme a demande inverse d'electrons. La reactivite du -lactame silyle a egalement ete exploree. L'aldehyde precurseur de la ()-ebelactone b, a ete synthetise en 13 etapes a partir du (r)-3-hydroxy-2-methylpropanoate de methyle, selon une strategie qui met en jeu une crotylboration de roush, une homoaldolisation de hoppe et un rearrangement-1,2 de wadman-kocienski comme etapes diastereoselectives-cles.

Full textAbstract:
Master of SciencePeriodontal disease is one of the most widespread diseases in humans and is characterised by chronic gingival inflammation and B cell accumulation and resorption of the crest of alveolar bone with subsequent loss of teeth. Porphyromonas gingivalis has been identified as a putative aetiological agent for periodontitis. The aim of the research presented in this thesis was to investigate, using in vitro systems, the responses of autoreactive B-1 and B-2 cells to enterobacterial and nonenterobacterial lipopolysaccharide (LPS) to shed light on the pathogenesis of chronic periodontitis and other diseases involving B cell accumulation and autoantibody production. The hypotheses tested were: (1) B cells respond differently to enterobacterial and non-enterobacterial LPS. (2) B-1 cells are activated by a lower concentration of LPS than B-2 cells. (3) LPS stimulation results in preferential accumulation of B-1 cells. Findings consistent with these hypotheses would provide new evidence for different roles for B-1 and B-2 cells in immune responses and that LPS stimulation could lead to B-1 cell accumulation in diseases thus characterised. Initial experiments investigated the responses of representative B-1 (CH12) and B-2 (WEHI-279) cell lines to preparations of P. gingivalis and Salmonella enteritidis LPS utilising flow cytometric and quantitative molecular methods. The cell lines responded differently to the two LPS preparations. There were significant but limited effects on viability and proliferation in the WEHI-279 cell line, but no significant changes in mRNA expression levels for genes including Toll-like receptors (TLR2, TLR4, RP105), immunoglobulin (IgM), cytokines (IL-6, IL-10), co-stimulatory molecules (CD80, CD86), and regulators of apoptosis (Bcl-2, Bax). In the CH12 cell line however, LPS stimulation had greater effect. Addition of S. enteritidis LPS from a threshold level of 100ng/mL was found to rescue the cells from death, reflected by the percentage viability and proliferation. Stimulation of CH12 cells with S. enteritidis LPS also led to a decrease in expression of RP105 mRNA, which may be part of a negative feedback loop. Interestingly, stimulation with low concentrations P. gingivalis LPS appeared to inhibit proliferation but high LPS concentrations stimulated proliferation of CH12 cells, although no further significant effects were noted in other analyses. Evidence was found that CH12 cells have a high basal level of activation. This suggests that this line is constitutively activated. Stimulation with P. gingivalis or S. enteritidis LPS did not affect the level of CD80 mRNA expression. It is possible that the CH12 line constitutively expresses a maximal level of CD80 (and possibly CD86) and further stimulation will not cause any increase. Since S. enteritidis LPS appeared to have more pronounced effects on both B cell populations, this LPS was used to further investigate B cell subset responses in a mixed splenocyte culture system. Experiments examining percentage viability and number of viable cells indicated that B-1 and B-2 B cells responded differently to LPS stimulation. A threshold level for B-2 cell response (significant increase in cell number) was found to be 100ng/mL LPS, in contrast to the B-1 B cell subset which were only significantly different to the unstimulated cells when stimulated with 50μg/mL LPS. By examining the expression of CD80, the majority of murine splenic B-1 cells were found to activated prior to any LPS stimulation in vitro. In contrast, the B-2 subset showed significant increase in CD80 expression only at high (≥10μg/mL) LPS concentrations. Studies of the division index of B-1 and B-2 cells showed a significant response in both subsets following stimulation with 1μg/mL and 10μg/mL LPS. However, overall, the results are inconsistent with LPS driving the preferential accumulation of B-1 cells in disease states. These experiments provided useful evidence that supported the idea that B-1 and B-2 cells respond differently to LPS. However, these studies were unable to directly address the role of P. gingivalis LPS in periodontitis. It may be that P. gingivalis LPS could have different effects to S. enteritidis LPS on primary B cells. It is still possible that B-1 cells may be more sensitive to P. gingivalis, as opposed to S. enteritidis LPS. Studies by other groups have suggested that the TH1/TH2 profile is skewed towards TH2 in chronic periodontitis and that P. gingivalis may drive this shift via its ability to signal through TLR2 (and modulate TLR4 signalling). Further, recent studies in our laboratories have found that P. gingivalis gingipains are able to polyclonally activate B cells and to break down both IFNγ and IL-12. Future studies should further examine the effects of B-1 and B-2 interactions in the mixed lymphocyte system together with subsequent studies utilising human periodontitis biopsies. The results presented in this thesis, together with work undertaken by other investigators, suggests that LPS could perturb the normal homeostatic mechanisms of the B-1 B cell-subset and increase polyclonal activation therefore contributing to the genesis of pathologies such as chronic periodontitis.

A vital part of this process is understanding the performance of the data acquisition system. Considerable effort was invested in the design and implementation of an application capable of collecting performance statistics from hundreds of CPUs in the data acquisition system during data collection. The monitoring application and some examples of its operation are presented in this thesis.

Le modele b-rel, defini a partir du modele b-relationnel de n. Le thanh se situe dans cette tendance. Son objectif est d'introduire un cadre general uniforme permettant l'extension progressive du modele relationnel vers le paradigme oriente objet tout en preservant au maximum ses acquis. Le caractere purement centre valeur du concept de relation est ainsi conserve (b-relation) et le concept de domaine est etendu en differentes etapes vers le concept de classe d'objet (b-domaine). Le lien entre les deux concepts est represente par les notions d'identificateur de b-tuple et d'operateur d'acces transversal permettant d'etablir des liaisons entre des valeurs localisees dans differentes b-relations. Les fondements logiques du modele b-rel sont definis a partir d'une logique centree objet, baptisee b-log, derivee des travaux de m. Kifer, g. Lausen et j. Wu sur f-logic. Cette logique est construite de maniere incrementale en mettant en evidence la representation des differents concepts tant au niveau de la syntaxe formelle qu'au niveau de la semantique. La notion syntaxique de description de base de donnees permet d'introduire deux approches de representation logique de l'information contenue dans une base de donnees b-rel: l'approche semantique caracterisee par la notion de modele de herbrand minimal, et l'approche axiomatique representee par la notion de theorie b-log.

Full textAbstract:
Studies of platelet MAO-B activity have revealed a link between low platelet activity and psychiatric syndromes characterized by an inability to control impulses and to anticipate future consequences of behavior (Oreland, 1980; Gottfries, von Knorring, & Oreland, 1980). These characteristics are fundamental to the construct of psychopathy, and we might therefore expect that psychopathy is associated with low MAO activity. Indeed, some investigators have suggested that low platelet MAO-B activity is a potential marker for vulnerability to psychopathy (Schalling, Asberg, Edman, & Oreland, 1987). However, no study to date has directly examined the association between platelet MAO activity and psychometrically-sound indices of psychopathy. The present study measured platelet MAO-B activity in a sample of 54 male offenders, assessed with the Psychopathy Checklist-Revised (PCL-R; Hare, 1991). PCL-R scores were not significantly related to level of platelet MAO activity. The results are discussed in terms of methodological issues involved in conducting biochemical research.Arts, Faculty of

Full textAbstract:
The aim of thesis was to study the effect of fluoranthene (FLT) on growth and biochemical processes of plant Petunia (Petunia hybrida cv. Lady blue) in in vitro conditions. In this experiment were used segments of the middle parts of the leaves, shoots from organogenesis in vitro and apical meristem of stem with four to five leaves from long-term in vitro culture. It was observed if fluoranthene influence organogenesis of shoots in vitro, contents of chlorophyll a and b, content of cytokinins and rating of shoots (from organogenesis in vitro) and apical meristem of stem with four to five leaves. It was used culture MS medium containing benzylaminopurin (1.5 mg/l), 1-naphtylacetic acid (0.18 mg/l) and fluoranthene (1 mg/l) or without fluoranthene (control). In the case of organogenesis in vitro, the experiment was performed at 4 different variations of media with subculturing to other media in triplicate. Variations of the media were chosen to allow period of cultivation with fluoranthene, which affects growth and biochemical processes. MS medium containing indol-3-butyric acid (0.5 mg/l) and FLT in different concentrations (0.1, 1, 3 a 5 mg/l) was used for monitoring rooting. The results showed that fluoranthen is able to affect organogenesis of shoots formed on the segments of leaves. There was lower frequency compared to the control organogenesis. It was found that fluoranthene more affects beginning of cultivation compared to later exposure of fluoranthene during cultivation. It was found the highest uptake of benzyladenine and its riboside from the culture medium. Fluoranthene affected significantly content of dihydrozeatin. Zeatin and its riboside were recorded in a minimal amount. Fluoranthene caused lower content of chlorophylls a and b in explantats. In the case of chlorophyll a were no significant differences between influence by fluoranthene at the beginning of the cultivation or during of cultivation. It was noted that fluoranthene influence the morphology of the roots subcultured shoots from organogenesis in vitro. Plant roots exhibited less branching and roots were shorter in culture medium containing higher content of fluoranthene (3 and 5 mg/l).

Nutritional factors with antioxidant properties, such as those contained in edible algae or green plants, might be implicated in protection against cancer development. Chlorophyll and other tetrapyrrolic compounds, structurally related to heme and antioxidant bile pigment bilirubin, belong to important candidate molecules, which might be responsible for these effects. Based on our studies demonstrating antiproliferative effects of S. platensis edible alga extract on experimental model of human pancreatic adenocarcinoma we investigated in detail the effect of chlorophyll occurring abundantly in this alga. Since only scarce data exist on the antiproliferative effects of chlorophylls, the aim of our study was to assess these effects. The study was performed on experimental models of human pancreatic and prostate cancer. The inhibitory effects of chlorophylls (chlorophyll a, chlorophyll b, chlorophyllin and pheophytin a) on cell proliferation and cell viability were investigated in in vitro studies. Chlorophylls reduced the mRNA expression as well as activity of hemeoxygenase in tested pancreatic cancer cells. Simultaneously, chlorophylls played an important role in redox environment of studied cancer cell lines including modulation of mitochondrial membrane potential, reactive oxygen species (ROS)...

The World Tourism Organization (UNWTO) has constantly promoted sustainable tourism development as well as played an important role since 1980; in addition, numerous standards were regulated accordingly. Under the impacts of both environment protection, energy saving and carbon reduction, the marketing strategy of numerous operators have been changes consequently. The ecological or environment lodging facilities gradually adopted by the people in this trade; nevertheless, there are still not appropriate criteria of green B&B for domestic lodge industry to carry out related strategies. One of the major aims of this study is to establish the criteria of green B&B and index of feasible implementation, and constitute index levels with fuzzy analytic hierarchy process (FAHP), as the major basis of conducting survey of adoption willingness of lodge operator in implementing environment protection strategy. Next, this study intends to explore the current status of environment strategy implemented by B&B manager as well as the factors influence the adoption willingness. Third, find out any other factors and significance that could affect the adoption willingness of B&B manager to carry out strategy. Fourth, this study intends to locate the factors and significance of influencing consumer in accepting environment protection strategy (lodging willingness). There are three research targets employed by the design method of this study, namely, representative experts and scholars in the related domain, for presenting construct index and significance degree; research model establishment of B&B manager, the green B&B index are used for interview and questionnaire survey methods, so as to confirm the aim of this study; and finally the research model establishment of lodge consumer, through hierarchical regression analysis and relevant statistic analysis, to explain significant meaning and reason of variables. The research result proves that green B&B index can be simplifies into eight main dimensions and concrete strategies (management and marketing, social participation and communication, energy management, water resources management, green purchase, solid waste treatment, green restaurant and lodge activities, natural and cultural resources), for reference by verification unit. Secondly, in the research model of B&B manager, environment knowledge behavior would influence the self-efficacy, and further affect the adoption willingness. For operator, the higher the compatibility of environment strategy is, the higher of adoption willingness will be. Finally, in the research model of consumer, the higher the frequency that consumer engaged in the environment related activity, the higher the willingness of selecting green B&B will be; while environment knowledge behavior would affect the perceived caracteristics of innovation, lodge preference, and attitude of engaging in environment activity of consumer. This study defines the implication of promoting green B&B development strategy is “to educate B&B managers attach more importance on environment ethics, and encourage consumer to change the attitude of recreation activity.” Furthermore, with the conception of simplified green lodge index, to direct towards tourism map planning of ecology village, apart from the unique features of “green B&B” image, to minimize the impact of recreation environment. By employing innovation diffusion theory (IDT) model in the behavior prediction of environment behavior and tourism behavior strategy, the result of this study could be served as a useful reference for following researches.

Accidental samples were collected from tourists who had lodged at B & B in Kenting in March of 2009. A total of 450 questionnaires were distributed and 403 of them were valid responses, yielding a valid response rate of 89.6%. The results of factor analyses and multiple regressions are as follows. There were six factors of travel motivations: activity, knowledge and social life, B & B characteristic, price, leisure and relaxation, and special interests in B & B. All of these factors of travel motivations can significantly influence repurchase intention. Moreover, B & B image can significantly influence repurchase intention. Finally, B & B image can completely mediate the impacts of factors about the price, leisure and relaxation, and special interests in B&B on repurchase intention. In addition, B & B image can partially mediate the effects of activity, knowledge and social life, and B & B characteristic on repurchase intention.
