Texte intégralRésumé :
Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Physics, 2010.Cataloged from PDF version of thesis.
Includes bibliographical references (p. 219-225).
In this thesis we study corrections to parton showers in the context of soft collinear effective theory (SCET). Monte Carlo event generators like Pythia or Herwig are heavily used by experimentalists to simulate events and they are indispensable tools to make exclusive theoretical predictions. They are based on a leading log parton shower algorithm that allows to resum the dominant contributions in the soft and collinear radiation. In this work we construct a framework to classify corrections to the parton shower that can be used to systematically improve event generators. We formulate parton showers as a standard matching procedure between a tower of soft collinear effective field theories called SCETi. We find two different kinds of corrections: hard-scattering corrections and jet-structure corrections. To relate these different effective field theories we make use of an important symmetry of SCET, called reparametrization invariance. In order to systematically study this symmetry, we construct operators that are invariant under reparametrization and we use them to find a minimal basis of operators that are homogeneous in the power counting. Complete basis of operators are constructed for pure glue operators for deep inelasting scattering at twist-4, for production of two and three jets from e+e- and for production of two jets via gluon fusion.

Texte intégralRésumé :
L'étude des populations naturelles des quatre Bromes de la sect. Genea en Bretagne montre que B. Sterilis et B. Diandrus ont une plus large amplitude d'abitat. Les caractéristiques édaphiques présentent une forte variation inter-sites pour les contraintes que peut subir la végétation. Pour essayer de relier l'exposition des populations aux embruns et l'amplitude de réponse des plantes à des traitements salin ou osmotique, des mesures de la plasticité ont été faites sur des marqueurs impliqués dans la croissance et le développement d'une part et dans les réponses aux stress d'autre part. Les résultats montrent que les enzymes antioxydants ainsi que les LOX et G6PDH ne répondent pas aux stress testés. En revanche, les variations des teneurs en amines avec les stress sont significatives. Ces variations concernent uniquement les individus de B. Sterilis, B. Madritensis et B. Diandrus issus de milieux soumis aux embruns et sont relatives au métabolisme d'oxydation de la Spd et de la Spm. Aucune des populations testées de B. Rigidus ne présente une telle plasticité. Ceci montre une association entre la plasticité du métabolisme des polyamines et le niveau de stress observé dans le milieu d'origine et de plus, suggère une relation entre cette plasticité et l'amplitude d'habitat de ces espèces. Puis, nous avons montré que la plasticité du métabolisme des amines en réponse à un stress salin était vérifiée sur la génération suivante et que cette plasticité présentait une diversité inter-famille pour ces espèces. Ceci suggère l'importance de cette composante de la variabilité biologique dans la capacité des espèces à répondre aux variations dans l'environnement. D'autre part aucune des huit familles testées de B. Rigidus ne présentaient cette plasticité, confirmant ainsi les résultats obtenus précédemment. De plus, on observe une variation de la connectance avec le stress salin différente suivant les espèces suggérant une régulation différente chez ces trois espèces.

Feri, Adeline. « Molecular mechanisms and signaling pathways involved in genome stability in the human fungal pathogen, Candida albicans ». Thesis, Sorbonne Paris Cité, 2016. http://www.theses.fr/2016USPCC246/document.
Texte intégralRésumé :
La levure Candida albicans présente une tolérance élevée aux réarrangements de son génome et en particulier, aux pertes d’hétérozygotie (LOH). Ces LOH sont le plus souvent le résultat de la réparation d’une cassure double-brin de l’ADN (DNA DSB) et jouent un rôle important dans différents aspects de la biologie de C. albicans. Afin d’étudier les mécanismes moléculaires à l’origine des LOH, nous avons combiné un système d’induction d’un DNA DSB par la méganucléase I-SceI et un système rapporteur de LOH optimisé pour l’analyse par FACS. La surexpression de I-SceI entraine une forte augmentation du taux de LOH, principalement des conversions géniques. La caractérisation des cellules ayant subi une LOH a permis d’identifier des allèles récessifs délétères et létaux présents à l’état hétérozygote dans le génome de la souche de laboratoire de C. albicans. Ces allèles influent sur la nature des LOH observés suite à un DNA DSB. Nous avons également caractérisé la fidélité de la réparation d’un DNA DSB induit par I-SceIchez C. albicans. Cette étude a permis de décrire des recombinaisons complexes et inattendues se déroulant pendant les événements de break-induced replication et de conversions géniques avec crossover. En parallèle, une collection de 564 plasmides de surexpression pour des gènes impliqués dans les voies de signalisation et dans l’intégrité du génome et de la paroi a été transformée dans une souche possédant les deux systèmes mentionnés ci-dessus. L’analyse des transformants dans des conditions ou non d’expression de I-SceI a permis d’identifier des gènes dont la surexpression augmente le taux basal de LOH ou diminue le taux de LOH élevé du à l’expression d’I-SceIThe Candida albicans genome displays a high tolerance to rearrangements, notably loss-ofheterozygosity (LOH) events. These events most often result from the repair of DNA double-strandbreaks (DSBs) and are known to play an important role in different aspects of C. albicans biology.To study the molecular mechanisms leading to LOH, we have combined an I-SceI meganuclease-dependent DSB-inducing system with a FACS-optimized reporter system of LOH. Our results show that expression of I-SceI leads to a dramatic increase in the frequency of LOH events,mainly gene conversion events. Characterization of cells having undergone a LOH led us to identify recessive lethal and deleterious alleles present in the heterozygous state in the genome of the C.albicans laboratory strain. These alleles influence the nature of the LOH events that are observed following a DSB. We also characterized the fidelity of the repair following an I-SceI-induced DNA DSB. This revealed unexpected complex recombination events occurring upon both break-induced replication and gene conversion with crossover repair events. In parallel, a collection of 564 over expression plasmids for genes involved in signaling pathways, genome integrity and cell wall integrity has been transformed in a C. albicans strainharboring the I-SceI-dependent DSB-inducing system and FACS-optimized LOH reporter. Analyses of the resulting transformants under conditions that allowed fro I-SceI expression or not, led to the identification of genes whose overexpression results either in an increase of the basal LOH rate or in areduction of the high LOH frequency associated to I-SceI expression

Texte intégralRésumé :
Abstract: Scent marketing is an area of predicted growth, with almost endless possibilities. It can successfully be applied to products, premises, places and services. Yet, this thesis explores some of the challenges scent marketing is likely to encounter, with regard to that part of the population who get sick from exposure to smells and chemicals. The purpose of this dissertation is to initiate communication and provide some tangible examples on how scent marketers and people suffering from the condition sensory hyperreactivity can co-exist in the same environment.
This paper presents a theoretical framework for the use of scent marketing, and the condition sensory hyperreactivity. The empirical study is of a qualitative nature, conducted through the mean of telephone interviews, on a sample of individuals with the condition, contacted through a website forum.
The findings show that people with this type of condition are substantially limited in their daily lives, due to scented products and places, and would be even more so with a growing use of this type of marketing. The possibilities for marketers could be to address the wishes of the interviewees, and gain a new market. The limitations for scent marketing are primarily of legislative nature, but could also include negative reactions to the subject. In addition to people with sensory hyperreactivity, and potentially young children, no specific target group could be outlined unsuited for scent marketing. Specific fragrances and chemical components to be avoided could in large not be determined. The interviewees wish for fragrance-free hospitals, dentists, waiting rooms and public places. The respondents have suggested a number of measures for marketers and shop owners that would facilitate and enable them to partake in the market place of today.
Keywords: Scent marketing, fragrance, sensory hyperreactivity, sensitivity

Orellana, Danilo Fernando Aros. « Floral scent evaluation of Alstroemeria ». Thesis, Cardiff University, 2010. http://orca.cf.ac.uk/55016/.
Texte intégralRésumé :
Alstroemeria is an important cut flower and its breeding has been developed focused on aesthetic characteristics and vase life longevity, but little is known about its scent. Five different genotypes were assessed including the non scented cultivars ‘Rebecca’ and ‘Samora’ and the scented cultivars, ‘Sweet Laura’, ‘Ajax’ and the species A. caryophyllaea. The scented Alstroemerias emitted the terpenoids: isocaryophyllene and ocimene as the major floral volatile compounds. Characterization of an Alstroemeria TPS (ALSTER) was based on four ESTs previously found in A. cv ‘Rebecca’. Rapid amplification of cDNA ends (RACE) was performed and the full length ORF was used for characterizations of the genomic organization and amino acid sequences (phylogenetic analysis). ALSTER genomic region contains five introns and six exons. This unique genomic organization classified ALSTER as a member of the class III with a merged 5-6 exon. The deduced amino acid sequence was classified into the subfamily TPS-b. A functional analysis showed enzymatic activity of ALSTER with geranyl diphosphate (GPP) and the monoterpene myrcene was the only product obtained. Gene expression evaluated through real time and semi q RT-PCR on eight different stages of development (SO to S7) showed high expression of ALSTER at around S2 - S4 in the scented Alstroemerias, coinciding with high scent emission perceived and also with the maturation of reproductive organs. Evaluations through surveys focused on level of liking of floral scent, were performed finding positive correlations between floral scent liking and floral appearance liking and between floral scent liking and floral scent intensity. Finally, 17 new lines of A. caryophyllaea were evaluated in terms of their morphology, phenology and productivity. Although none of them were suitable for the market because of their low productivity, short stems and small flowers, they were all scented and identified as promising starting points for breeding purposes.

Ett ord jag har hittat längs vägen och fastnat för är ordet ”minnesbilder”. Till en början var det ett ord som löst beskrev ett projekt, två keramiska tavlor med abstrakta, intuitivt målade motiv. När jag har arbetat intuitivt har fälten fått växa fram allt eftersom vad som känns bra och någonstans längs vägen har jag formulerat att färgerna, formerna och stämningen i målningarna kommer från en inre värld av bilder: minnen.

Texte intégralRésumé :
Solar cells are the primary energy-collection agents used onboard spacecraft converting energy from the sun into electricity. With solar cells being the main source of power for satellites, it is important to know how they operate and degrade when exposed to the harsh environment of low earth orbit. The objective of this thesis is to estimate the solar cell degradation that will be experienced on orbit due to radiation. This linked with the mission of the NPS-SCAT providing a quantitative measurement on orbit of how solar cells degrade over time can reduce risk of expensive national satellite by providing real-life solar cells exposure to threats of the space environment. A secondary goal of this thesis is to build and present a representation of the CONOPs (concept of operations) that describes the functionality expected on orbit. Coordination with the software programmers as well as the staff to set robust functionality is the goal for the CONOPs. This software package will be programmed into the two 1U flight certified CubeSats as their standard programming once implementation and testing have been completed.

Texte intégralRésumé :
Det här projektet börjar med frågeställningar kring att kunna eller inte kunna ta plats i staden och hur platstagande kan skapa förändring. Genom iscensättande (att göra en scen), med strategierna: omhändertagande, närvarande och platstagande vill jag undersöka, synliggöra och sätta igång delat platsgörande i det offentliga rummet. Jag har börjat på skenbart* övergivna platser och i temporära rum: För att den skenbart övergivna platsen bara ser ut att vara oanvänd och kan, med lite fantasi, göras om till det som behövs för stunden. För att i de spår som lämnas uppstår gåtor och mysterier, möjliga framtider och drömmar om andras äventyr. För att lusten att inta scenen ibland kräver stunder av tomma scener att inta. För att delande också är att turas om. *Med skenbart övergivna menar jag platser som tidvis upplevs oanvända men inte är det. Platser med spår av tidigare aktivitet och inspiration till framtida händelser.My degree project begins with questions formulated around the ability, or inability to take and make space in the city and how taking place can create change. By staging (making a scene) using the strategies, taking care, being present, and taking space, I want to explore, make visible and set in motion shared place-making in our common rooms. I have started in seemingly* abandoned places and in temporary rooms: Because the seemingly abandoned only appears to be unused and can, with a little imagination, be made into what is needed for the moment. Because traces that are left behind become mysteries, possible futures and dreams of the adventures of others. Because the desire to take the stage sometimes requires moments of empty stages. Because the act of sharing also means taking turns. * With seemingly abandoned I mean places that sometimes appear unused, but are not. Places with traces of past activity and inspiration to future happenings.

Texte intégralRésumé :
In this experiment it was investigated how scent affect the memory. Encoding information in the same context as retrieving it has been suggested to be beneficial for memory, earlier research has mostly explored how environmental contextual cues affects the memory. In this research the contextual cue was created by a presentation of a scent. The participants were presented with two lists of words, during the encoding of the first list all the participants were presented with a scent, half of the group was directed to forget the first list straight after encoding and the other half to keep remembering the list. For the second list no one was presented with a scent. In the retrieval of both lists half of each group was reinstated with the scent they were presented with at encoding and the other half without the scent (control group). The data were analysed with univariate ANOVAs and significant effects were followed up with independent-samples t-test. The results were that participants that were reinstated with the scent were thought to remember more than the others, however there was only a significant difference in the forget condition with reinstatement, where they remembered less than in the other conditions.

Texte intégralRésumé :
Le présent travail vise à dégager l'articulation de la volonté et de l'infini en acte. Il s'agira de montrer comment seule une pensée de la volonté comme telle permet l'inscription d'un infini en acte, à partir de l'oeuvre du théologien écossais Jean Duns Scot. Il s'agira d'abord d'examiner dans une première partie comment Duns Scot s'efforce de penser la volonté comme volonté. Il l'arrache à son statut traditionnel d'appétit intellectuel et l'identifie à la rationalité. Une logique de la liberté sera dégagée comme logique de la puissance absolue, assurant une réhabilitation de la contingence. La seconde partie montrera comment Duns Scot déduit l'infini en acte de la volonté et comment la logique de la liberté est une logique de l'infini actuel. Cette logique de l'étant est subordonnée à celle de l'infini en acte. Elle demande à être comprise dans une étroite connexion avec le concept de toute-puissance. Avec Duns Scot se défait l'identification de la limite et s'opère une subversion du principeThis present work aims at bringing out the articulation between the will and the infinite in actuality. Our purpose is to show how only a conception of the will as such will allow the inscription of an infinite in actuality, from the works of Scottish theologian John Duns Scot. .

Mestrado em Engenharia de Computadores e TelemáticaA Internet das Coisas e uma área que tem vindo a crescer ao longo dos anos e que tem suscitado grande interesse por parte das indústrias. A evolução conseguida nos últimos anos nas comunicações sem fios e sensores e atuadores tem aumentado o número de comunicações Máquina-a-Máquina no mercado. Esta evolução fez com que o número de soluções Máquina-a- Máquina aumentasse constantemente com o número de dispositivos a aumentar também, nestas soluções. Devido a este aumento do número de dispositivos em soluções Máquina-a-Máquina, a complexidade de gestão destes dispositivos torna-se cada vez mais difícil. Devido a isto, existe a necessidade de ter uma solução horizontal de gestão de dispositivos que permita a gestão desses dispositivos. Atualmente existem standards que permitem fazer esta gestão de dispositivos. As implementações destes standards de gestão, por vezes não suportam as funcionalidades necessárias para determinada solução no mercado. Nesse sentido, esta dissertação propõe uma solução de gestão de dispositivos numa plataforma IoT existente, promovendo a interoperabilidade entre os dispositivos e os protocolos de comunicação.
The Internet of Things is an area that has been growing through the years and has raised a lot of interest in the industries. The improvements made in wireless communications and sensors/actuators has allowed the increase of Machine-to-Machine communications in the market. This evolution has been causing a continuous increasing of the number of Machine-to-Machine solutions along with the number of devices in those solutions. Due to this increase in the number of devices on Machine-to-Machine solutions, the complexity of managing these devices becomes more and more di cult. For this reason, there is a need to have a horizontal solution that allows the management of those devices. Currently, there are standards that enable device management in IoT/M2M solutions. The implementations available of these device management standards sometimes do not ful ll the needs of the current market in IoT. Consequently, this dissertation proposes a possible device management solution into an existing IoT platform, promoting interoperability between devices and their communication protocols.

Texte intégralRésumé :
L'objectif de ce travail de recherche est d'identifier les facteurs d'intégration de l'information environnementale dans les décisions urbaines à partir d'une approche pluridisciplinaire. Une analyse des pratiques et les apports des sciences sociales et de l'ingénieur ont permis de dégager 3 points de vigilance qui serviront de support théorique à l'élaboration d'une proposition de tableau de bord environnemental d'aide à la décision dans le cadre des SCOT. Le premier fondement du tableau de bord environnemental est le développement de l'innovation organisationnelle qui demande, au préalable, la confrontation des visions du territoire par les différents acteurs porteurs des enjeux. En fonction des territoires et des contextes politiques, l'identification de ces acteurs-porteurs d'enjeux peut se faire différemment. Dans le cadre du tableau de bord environnemental, le principe choisi sera de produire un cadre de référence des acteurs à mobiliser. Le second fondement est la recherche de la réduction des incertitudes pour les thèmes identifiés comme des enjeux importants pour le territoire. En raison de la complexité du système informationnel lié à l'environnement, une hiérarchisation des besoins en terme d'information est proposée. Deux socles de connaissance seront ainsi mobilisés. Le premier cherche à donner une image globale des enjeux du territoire à partir de données immédiatement disponibles. Cela servira de support à la hiérarchisation des enjeux environnementaux. Le second socle informationnel correspondra à des données localisées produites par les acteurs. Enfin, le dernier fondement du tableau de bord environnemental concerne l'évaluation du processus décisionnel à partir de deux aspects : la mobilisation des acteurs en fonction des enjeux identifiés sur le territoire, et la cohérence entre les projets du SCOT, notamment par rapport aux enjeux environnementaux.

Texte intégralRésumé :
This thesis focuses on the political dimensions of aesthetic expression during the Long Sixties. The thesis deals with amateur theatre ventures both within and linked to the social democratic labour movement. ’Spelet om Norbergsstrejken’ (The Play about the Norberg Strike) had its première in 1977 in a small industrial village in the industrial region of Bergslagen. Similar plays appeared in many regions of the country and a wave of workers’ plays emerged and made an impact on the internal investments of the educational association ABF in amateur theatre. The empiricism of the thesis concludes in 1982 when a social democratic amateur theatre association was founded and after a breakaway from the social democratic movement was establishing a residential study centre in another small village in Bergslagen. Sixties radicalisation provides the social context of the study and the perspective of sociological social movement research is used and developed. Based on the perspective of cognitive practice and the concepts of cosmology and movement ideology attention is directed towards the theatre assets of performance hosts, expectation horizons and patterns of behaviour. The thesis argues for a deeper understanding of sixties radicalisation partly meaning that the periodisation needs to be extended backwards as well as forwards in terms of time and partly that the political dimensions of aesthetic expression should be focused on. Based upon the results of the thesis the concept of culturactivism was formulated which defines the specific approach that appeared in the space between political and cultural activism. This highlights the need for a concept that covers the cognitive free space that arose between aesthetic expression and political activism and which has not previously attracted the attention of historical studies about sixties radicalisation to any great degree.

The sense of smell is a mystery-and the human sense of smell is a particularly inscrutable one. Only in the last 25 years have scientists identified the molecules in our noses responsible for detecting odors, and since then, the unexpected discovery of a new family of olfactory detection molecules has complicated the story. When the complexities of the human brain, human motivation, and human variation are added to the mix, the question of what smells do to and for us becomes even more perplexing-and intriguing. Essayist and physician Lewis Thomas wrote that understanding the sense of smell "may not seem a profound enough problem to dominate all the life sciences, but it contains, piece by piece, all the mysteries." Scientists from all fields are coming together to solve these mysteries of olfaction, and their investigations are starting to reveal that the sense of smell can move us in ways that we aren't even always aware. While it's clear that scientists are far from closing the case on smell, it is also becoming increasingly obvious that the power of the human nose is nothing to sniff at.

Texte intégralRésumé :
Med användning av ramverk kan förenkling av utritningen med pixel- och vektorgrafik i webbläsaren ske vid användning av WebGL API:t och Canvas 2D API:t. Men problemet är, att en dålig utritningshastighet är inget som vill upplevas när en 2D scen ritas ut i en webbapplikation. Genom att jämföra olika ramverk mot varandra, som använder sig av WebGL API:t eller Canvas 2D API:t, togs det reda på vilket av dessa ramverk som var snabbare i utritning. Tre ramverk valdes ut till studien för att göra mätningar på. Det implementerades en webbapplikation för att jämföra hur lång tid en utritning tar i de valda ramverken vid olika scenarier. Resultatet visade att ett hybridramverk som använde sig av förstnämnda API:t och föll tillbaka på andranämnda API:t var snabbare i 9 av 10 scenarier. I en fortsatt studie skulle flera ramverk kunna jämföras och även jämföras i olika användningsfall för att se hur ramverken presterar i dessa.

Texte intégralRésumé :
Studier i Sverige har visat att skådespelare rapporterar högre nivåer av upplevd stress, ångest och fysisk smärta än generell population, men lägre nivåer av psykisk ohälsa och depression. Studiens syften var att undersöka upplevd stress, coping och personlighetsdrag hos teaterarbetare och jämföra med generell population, samt utreda betydelsen av anställningsförhållanden och yrkesutövning för upplevd stress och coping. Brief COPE, Perceived Stress Scale och Swedish universities Scales of Personality användes. De 304 respondenterna självskattade högre nivåer av upplevd stress och neuroticism än generell population, men lägre nivåer av aggression. Yrkesutövning, anställningsförhållanden och coping hade ingen effekt på upplevd stress. Signifikanta skillnader avseende copingstrategier upptäcktes, där frilansande scenartister i högre utsträckning använde sig av både dysfunktionella och funktionella copingstrategier. Vidare forskning behövs för att klargöra vilka faktorer som fungerar som skydd mot stress hos olika individer, och omvärdera vilka kombinationer av copingstrategier som skapar effektiv stresshantering bland teaterarbetare.

Popular control methods have ranged from lethal techniques, extirpating the animal, to multiple non-lethal methods focused on deterring undesired behavior. In the past, lethal methods were the preferred choice. However, with increased awareness of the need for biodiversity conservation, new management methods focus on non-lethal control, with emphasis on exploiting aspects of naturally occurring organismal behaviors and ecology. Over the past decade, technological advances in extraction method’s and equipment have also developed new techniques providing a broader range of information about species biology for management use. One of the most well documented conflicts between wildlife and humans is that of the wolf. Using advanced technology and new techniques, we investigated the implication of using chemosensory signals in canid urine to modify behavior as a possible non-lethal alternative in large predator management. Here we used the SBSE method coupled with improved GC/MS equipment to analyze the volatile organic compounds in the urine of four canid species, gray wolf (Canis lupus), red wolf (Canis rufus), wolf-dog hybrids (Canis familiaris) and the domestic dog (Canis familiaris) in order to create working urinary profiles. The extraction method identified several compounds also seen in the urinary profiles of other large predators. In addition, similarities and differences were also noted between taxa and the sexes, and these can be further explored in future studies. Two identified urinary compounds, acetophenone and methyl propyl sulfide, were selected for further behavioral evaluation. We focused on these compounds and their influence as chemosensory signals triggering urine marking events in both the gray wolf and red wolf. Behavioral observations of the effects of these two chemicals indicated they elicited responses from captive wolves. At each of the three study sites, the combination of these chemicals produced urine-marking events along the territory boundary by dominant animals. As a result, the investigation focused on what triggered the urine-marking events, the chemicals themselves, their combination, or the breakdown of the chemicals producing other odorants. It was found that there was no significant degradation of the chemicals over time and environmental conditions produced no significant breakdown of the acetophenone prior to the addition of methyl propyl sulfide. This posed a number of new questions and illustrated the need for additional behavioral studies. The results of this study analyzing chemosensory signals in canid urine, provides biologists with new information to aid in the development of new non-lethal management strategies for handling problematic wildlife as well as providing useful information for future research involving reproduction, predator/prey dynamics, territory maintenance, and a host of other studies focusing on animal ecology in association with chemosensory signaling.

Texte intégralRésumé :
Integrinas são glicoproteínas transmembrânicas envolvidas na adesão célula-célula e célula-proteina da matriz extracellular (ECM) que participam da migração e fusão de células trofoblásticas gigantes (TGC) com células do epitélio materno no placentoma bovino e interagem com inibidores teciduais de metalloproteinases (TIMPs), considerados importantes reguladores das metaloproteinases de matriz (MMPs), que são reconhecidas como passo limitande para ação de enzimas que atuam no remodelamento da ECM na implantação e na gestação. Uma vez que as integrinas são consideradas responsáveis pela manutenção da arquitetura tecidual e que as MMPs podem regular a degradação e a reconstituição da ECM necessária para a invasão do trofoblasto, temos como objetivo verificar uma possível relação das integrinas com alterações placentárias comumente observadas em gestações de animais clonados (SCNT). Para avaliar a funcionalidade placentária, a expressão do lactogênio placentário (PL) e do antígeno Ki-67 foram também verificadas. Placentomas bovinos foram coletados e divididos em 3 grupos: 1) início (n = 6) e 2) final (n = 3) da gestação de animais derivados de monta natural (n=9) e final da gestação de animais clonados (n=8), clones machos (n=4) e clones fêmeas (n=4). As proteínas foram localizadas por imuno-histoquímica indireta, exceto as subunidades de integrina α6, β1, αV e β3 que foram localizadas por imunofluorescência. A especificidade dos anticorpos e expressão protéica foi confirmada por Western blot e a expressão do RNAm foi avaliada por meio de RT-PCR e PCR em tempo real quantitativo. As células positivas para a laminina, TIMP-2, Ki-67 e lactogênio placentário (PL) foram quantificadas e para comparação entre os grupos. A proteína das subunidades α6 do receptor de integrina e β1 foi observada nos animais clonados e não clonados nos estromas materno e fetal e porção basal dos epitélios materno e fetal e foi co-localizada com a laminina. A proteína das subunidades αV e β3 do receptor de integrina foi observado nos estromas materno e fetal e foi co-localizado com a fibronectina. O TIMP-2 foi exclusivamente e especificamente localizado nas TGCs no início e final da gestação de animais clonados e não clonados, mas não houve diferença significativa em sua expressão. O PL apresentou a mesma localização do TIMP-2 em todos os grupos analisados. Houve diferença significativa (p<0,05) entre 270d e clones ao se comprar a expressão relativa do RNAm da subunidade de integrina β1 e do lactogênio placentário e ao se comparar a expressão protéica por western blot da laminina e do TIMP-2. Foi possível observar diferença significativa (p<0,05) entre o grupo controle e o grupo de animais clonados ao se quantificar o número de TGCs positivas para a laminina e para o lactogênio placentário. Apesar de algumas diferenças terem sido observadas na expressão de integrinas e de proteínas da ECM, sugere-se que a interação das integrinas com seus ligantes da ECM a termo não é um determinante da sobrevivência neonatal de bovinos clonados. Contudo, outros estudos são necessários para esclarecer se estas proteínas representam elementos chave na placentação de bovinos clonados em início de gestação. As diferenças observadas na expressão de integrinas e principalmente do PL entre clones fêmeas e machos sugerem possível influência de genes associados ao cromossomo sexual ou imprinting.Integrins are transmembrane glycoproteins involved in cell-cell and cell-extracellular matrix (ECM) adhesion and signal transduction. They participate in the migration and fusion of trophoblast giant cells (TGC) with uterine epithelial cells in bovine placentomes, and interact with tissue inhibitors of metalloproteinases (TIMPs), considered important regulators of matrix metalloproteinases (MMPs). MMPs are rate-limiting enzymes degrading ECM proteins during tissue remodeling around embryo implantation, pregnancy and parturition. Since integrins are considered to be responsible for the maintenance of the architecture within tissues and MMPs may also regulate degradation and reconstitution of ECM required for trophoblast invasion, we aimed to verify a potential relation of integrins with common placental alterations observed in cloned animals (SCNT). To verify the placental functionality, expression of placental lactogen (PL) and Ki-67 antigen was also assessed. Bovine placentomes were collected and divided into 3 groups: 1) early and 2) late gestation derived from natural mating (n=9) and 3) late gestational bovine clones (n=8), also divided into male clones (n=4) and female clones (n=4). All proteins were localized by indirect immunohistochemistry except for integrin subunits α6, β1, αV and β3 that were shown by immunofluorescence. The antibody specificity and protein expression were confirmed by Western blot. Expression of mRNA was evaluated using RT-PCR and quantitative Real Time PCR. Positive cells for laminin, TIMP-2, Ki-67 and placental lactogen were quantified for comparisons among groups. The protein of integrin receptor subunits α6 and β1 was observed in both cloned and non-cloned animals in the fetal and maternal stroma and at the basal membrane of maternal and fetal epithelial cells, co-localized with laminin and with collagen IV. The integrin receptor subunits αV and β3 were observed in the fetal and maternal stroma, co-localized with fibronectin. TIMP-2 was specifically and exclusively localized in TGC in the early and term gestation in both cloned and non-cloned animals. PL has shown the same localization of TIMP-2 in all analyzed samples. Statistically significant differences (p<0,05) between term gestation of non-cloned and cloned animals were observed comparing the mRNA expression of integrin β1 subunit and placental lactogen and the protein expression of laminin and TIMP-2. There were also statistically significant differences (p<0,05) between non-cloned and cloned animals in the number of laminin and placental lactogen positive cells. Despite some differences in integrin and ECM proteins expression, our results suggest that the interaction between integrins and their ECM ligands in term gestation is not a determinant for the survival rate of newborn cloned calves. However further studies are necessary to elucidate if integrins represent key elements in the early placentation of SCNT bovines. The differences found in the integrin and principally in the placental lactogen expression between female and male cloned calves suggests the influence of sex-chromosome associated genes or imprinting.

Texte intégralRésumé :
Remote Explosives Scent Tracing (REST) is the concept of bringing the mine field to Mine Detection Dogs or Rats, instead of vice versa. This is done by collecting air or dust from minefields, and taking these samples to a laboratory environment, where they are subsequently analysed by the detection animals.
REST has previously proven to be very fast and cost effective, but one of the issues facing the method is that there is yet no reliable tool for sampling dust. In earlier sampling units, air has been collected in filters. However, the concentration of scents related to mines has been seen to be a million times higher in dust particles than in air sampled from above the ground. The aim of this project was to evaluate and improve a dust sampling prototype constructed in the beginning of 2010. The project was initiated in cooperation with the GICHD (Geneva International Centre for Humanitarian demining), and carried out in cooperation with APOPO (Anti-Personnel Landmines Detection Product Development).
During this project, information was gathered on the samplers that have previously been used for REST. A new prototype was made in Trondheim in cooperation with NTNU (Norwegian University of Science and Technology). With this new sampler prototype, tests were made in a laboratory environment at NTNU as well as at APOPO’s test mine field in Morogoro, Tanzania. Several obstacles were faced, such as difficulties to test and evaluate the sampler during the rainy season, insufficient air supply for the prototype, and issues with the laboratory equipment in Morogoro. Due to this, the number of tests performed and the number of repetitions of each test was not as high as would have been desired.
The results of the information gathering and the tests are presented in this report, and the knowledge and experience gained resulted in several suggestions for improvements for the sampler prototype. A suggestion for a grid design that would cover the entire mouth piece, with a built-in distance to the suction inlet, in order to avoid both clogging of the grid and that too much dust is sucked in if the mouth piece touches the ground and a fully adjustable sampling unit. Several other recommendations are given that would reduce cross contamination risks and improve ergonomics and other aspects of the sampler prototype.

Texte intégralRésumé :
The automation of most of our activities has led to the continuous production of data that arrive in the form of fast-arriving streams. In a supervised learning setting, instances in these streams are labeled as belonging to a particular class. When the number of classes in the data stream is more than two, such a data stream is referred to as a multi-class data stream. Multi-class imbalanced data stream describes the situation where the instance distribution of the classes is skewed, such that instances of some classes occur more frequently than others. Classes with the frequently occurring instances are referred to as the majority classes, while the classes with instances that occur less frequently are denoted as the minority classes.
Classification algorithms, or supervised learning techniques, use historic instances to build models, which are then used to predict the classes of unseen instances. Multi-class imbalanced data stream classification poses a great challenge to classical classification algorithms. This is due to the fact that traditional algorithms are usually biased towards the majority classes, since they have more examples of the majority classes when building the model. These traditional algorithms yield low predictive accuracy rates for the minority instances and need to be augmented, often with some form of sampling, in order to improve their overall performances.
In the literature, in both static and streaming environments, most studies focus on the binary class imbalance problem. Furthermore, research in multi-class imbalance in the data stream environment is limited. A number of researchers have proceeded by transforming a multi-class imbalanced setting into multiple binary class problems. However, such a transformation does not allow the stream to be studied in the original form and may introduce bias. The research conducted in this thesis aims to address this research gap by proposing a novel online learning methodology that combines oversampling of the minority classes with cluster-based majority class under-sampling, without decomposing the data stream into multiple binary sets. Rather, sampling involves continuously selecting a balanced number of instances across all classes for model building. Our focus is on improving the rate of correctly predicting instances of the minority classes in multi-class imbalanced data streams, through the introduction of the Synthetic Minority Over-sampling Technique (SMOTE) and Cluster-based Under-sampling - Data Streams (SCUT-DS) methodologies. In this work, we dynamically balance the classes by utilizing a windowing mechanism during the incremental sampling process. Our SCUT-DS algorithms are evaluated using six different types of classification techniques, followed by comparing their results against a state-of-the-art algorithm. Our contributions are tested using both synthetic and real data sets. The experimental results show that the approaches developed in this thesis yield high prediction rates of minority instances as contained in the multiple minority classes within a non-evolving stream.

Texte intégralRésumé :
Detta arbete syftar till att undersöka de relationer som uppstår mellan teaterrekvisita, skådespelare och ljudtekniker genom det posthumanistiska perspektivet agentiell realism. Jag utforskar även vilka fenomen som uppstår ur dessa relationer. Vad händer när sensorer implementeras i rekvisitan så att skådespelarna själva kan trigga vissa ljudeffekter från scenen? För att undersöka detta har jag tagit fram prototyper av teaterrekvisita med sensorer och på så sätt i viss mening gett föremålen en egen röst. Detta bidrar till att de kan delta i dialogen med människorna i en föreställning, samtidigt som samspelet mellan skådespelare och ljudtekniker förändras. Genom processens olika iterationer har gränsen mellan subjekt och objekt blivit allt mer otydlig, liksom den mellan de olika rollerna. Skådespelaren blir i viss mening ljudtekniker, liksom både rekvisitan och ljudteknikern i sin tur blir skådespelare.This thesis aims to investigate the relationships between theatrical props, actors and sound engineers through the posthumanistic perspective of agential realism. I also explore the phenomena that emerge from these relationships. What happens when sensors are implemented in the prop in order for the actors themselves to trigger certain sound effects from the stage? To investigate this, I have developed prototypes of theater props with sensors and thus in some sense given the objects a voice of their own. This contributes to them participating in the dialogue with the people in a performance, while at the same time changing the interplay between actors and the sound engineer. Through the different iterations of the process, the division between subject and object has become increasingly unclear, just like the one between the different roles. In some sense, the actor becomes an audio engineer, as both the prop and the audio engineer in turn become actors.

Texte intégralRésumé :
La recombinaison homologue est un mécanisme de réparation de l’ADN extrêmement contrôlé et particulièrement chez les eucaryotes supérieurs. Dans les cellules méiotiques de ces derniers, où les cassures doubles brin de l’ADN sont programmées, les voies de crossing-over de la recombinaison homologue, qui génèrent de nouvelles combinaisons de gènes, sont restreintes. Dans les cellules somatiques, la recombinaison illégitime, qui assure majoritairement la réparation des cassures double brin de l’ADN, limite l’intégration ciblée du transgène par recombinaison homologue. Les entreprises de biotechnologie convoitent de maitriser la recombinaison homologue afin de contrôler d’une part le brassage génomique qui a lieu pendant la méiose, et d’autre part l’intégration du transgène dans le génome. Cette étude a porté sur le développement d’outils afin d’atteindre ces deux objectifs. Afin d’augmenter le brassage du génome, ayant lieu pendant la méiose, une version du promoteur OsDmc1b, active dans les cellules méiotiques, a été caractérisée chez le maïs. Des plantes sur-exprimant le gène ZmSpo11.1, sous contrôle de ce promoteur, ont ainsi été développées afin d’obtenir des lignées potentiellement hyper-recombinantes. Si la surexpression de ZmSpo11.1 permet effectivement d’augmenter le taux de crossing-over, il pourra être utilisé par les sélectionneurs afin d’accélérer l’introgression d’allèles d’intérêt dans des variétés élites. Concernant la mise en place d’une technique de ciblage de gène, deux stratégies, reposant sur l’utilisation de la méganucléase I-SceI, ont été testées. La démarche a nécessité trois éléments : un locus cible contenant le site de coupure I-SceI, une matrice de réparation et la séquence codant I-SceI (ou I-SceI::GR). La première stratégie, consistant à retransformer les lignées présentant le locus cible avec la matrice de réparation et I-SceI, ne semble pas exploitable car aucun évènement de ciblage de gène n’a été mis en évidence. La seconde stratégie, reposant sur l’assemblage des trois éléments par croisement, est beaucoup plus prometteuse. Malgré la faible activité d’I-SceI::GR, des évènements de recombinaison homologue ont été observés dans les tissus foliaires de certaines plantes. Du cal embryogène, développé à partir de ces dernières, a permis de régénérer des plantes présentant des évènements de ciblage de gène. Ces travaux ouvrent de nouvelles perspectives dans l’élaboration contrôlée d’OGMHomologous recombination is a DNA repair mechanism highly regulated in higher eukaryotes. In their meiotic cells, where DNA double-stranded breaks are programmed, the crossing-over pathway of homologous recombination, which generates new gene combinations, is limited in activity and genomic distribution. In somatic cells, illegitimate recombination, which mainly ensures DNA double-strand repair, limits the targeted integration of transgenes by homologous recombination. Biotechnology companies aim to master homologous recombination to control on the one hand the genomic mixing that occurs during meiosis, and on other hand, the integration of transgenes into the genome. This study focuses on the development of tools to achieve these two objectives.To increase genome mixing occurring during meiosis, a version of the OsDmc1b promoter active in maize meiotic cells was isolated. Then, plants over-expressing the ZmSpo11.1 gene under control of this promoter have been developed to obtain potentially hyper-recombinant lines. If ZmSPO11.1 overexpression increases the crossing over rate, it can be used by breeders to accelerate the introgression of alleles of interest into elite varieties. For the establishment of a gene targeting technique, two strategies based on the use of the I-SceI meganuclease were tested. These approaches involved the use of three elements which are: a target locus containing the cleavage site of I-SceI, a repair template and the sequence encoding I-SceI (or ISceI::GR). The first strategy, consisting of the retransformation of target locus lines with the repair template and I-SceI, does not seem workable because no gene targeting events were isolated. The second strategy, based on the assembly of the three components by crossing, is more promising. Despite the low activity of I-SceI::GR, homologous recombination events were observed in leaf tissues of certain plants. Embryogenic callus, developed from these plants, permitted the regeneration of plants with gene targeting events. This work opens new perspectives in the development of controlled GMO production

The objective of the study is to examine whether the experience from language courses abroad has had any impact on the career choices for four individuals. Based on a qualitative research methodology, four semi-structured interviews have been executed. The two research questions have been answered by letting four people recount their experiences from language courses abroad linked to their self-images and career choices. The outcome is that the experiences from the language courses contributed to a more or less altered self-image. Most of all, the interpersonal abilities were fostered, which led to the formation of a self-image characterized by improved confidence in social settings. The four individuals’ self-images have then impacted their career choices, however in different ways. The perceptions of their own abilities have played an important role in their choices of career paths.Studiens syfte är att undersöka om fyra individers upplevelser av språkresan har haft betydelse för deras karriärval. Utifrån en kvalitativ forskningsmetod har fyra semistrukturerade intervjuer genomförts. Genom att låta fyra personer berätta om sina upplevelser av språkresan kopplade till deras självbilder och karriärval har studiens två forskningsfrågor kunnat besvaras. Resultatet visar att upplevelserna av språkresan bidrog till en mer eller mindre förändrad självbild hos dessa personer. Framför allt främjades den sociala utvecklingen, vilken medförde att en självbild kännetecknad av högre tilltro till sig själv i sociala sammanhang formades. De fyra personernas självbilder har i sin tur påverkat deras karriärval, om än på olika sätt. Bilden om den egna förmågan har spelat en viktig roll i val av karriärbana.

Texte intégralRésumé :
Human scent has been the focal point of diverse scientific interests and research initiatives for the past several years. The knowledge gained about its composition has favored the advancement of multiple disciplines, and promoted the development of a wide variety of applications. Among these applications is the use of human scent as a resource for Forensic investigations, where scent profiles are often used as evidence to associate individuals to the scene of a crime. The characteristic nature of individual human scent has enabled this type of evidence to be used as a biometric tool for the differentiation of subjects. Nevertheless, the present study discusses a new perspective towards human scent's role and application in Forensic investigations. The foundation of this new perspective consists of employing human scent’s biometric quality to classify individuals using common traits.
In this research study, underarm and hand odor samples were collected from Caucasian, Hispanic and East Asian individuals, of both genders. Subjects were also organized into 3 different age groups: 18-30, 35-50 and 55+ years. Headspace Solid Phase Micro-extraction Gas Chromatography Mass Spectrometry (HS-SPME-GC-MS) was used to create individual scent profiles for the evaluation of subject classification by age, gender and race/ethnicity. Individual classification was assessed through the identification of qualitative and quantitative patterns in the volatile organic compound (VOC) constituents that characterize human scent. Principal Component and Linear Discriminant analyses of the collected scent profiles, led to the identification and validation of characteristic VOC marker combinations for age, gender and race/ethnicity. Statistical analysis facilitated group classification and differentiation on the basis of these traits. Moreover, this study also evaluated the use of solvent extraction as a complementary technique to HS-SPME for human scent analysis. Findings from this assessment revealed that the simultaneous consideration of data from both extraction techniques favors an enhancement of the classification of subjects by means of human scent.
The discoveries achieved in this study represent a significant step for human scent as a forensic tool. The outcome of this research has cleared a new path for further human scent investigation, and highlighted its further relevance to forensic applications.

This thesis aims to create a better branding message for the OLIVITA Artisan by finding specific scents that are closely aligned with its marketing strategy for their future product line, to reassure the existing brand image and increase its competency in the market. In order to find the scents that are aligned with OLIVITA Artisan's existing brand image, an edited version of the Zaltman Metaphor Elicitation Technique (ZMET), a patented market research tool that has been proven successful in eliciting the conscious and more importantly the unconscious thoughts by exploring people's non-literal or metaphoric expressions, was applied for the "Mediterranean life" concept among a convenience sample. The transcriptions of the interviews were analyzed, relevant statements were extracted and the strongest statements were selected and logically grouped to be able to identify the key themes in consumer's mind by Voice of the Customer analysis. The themes were also used to create short stories. The results shaped the scent recommendations for the OLIVITA Artisan, including four pure, three conceptual scents that are closely aligned with its brand image.

Texte intégralRésumé :
The purpose of this master thesis is to evaluate the results from the completed SCPT (Seismic Cone Penetration Test) surveys with respect to the methods ability to estimate dynamic young´s modulus. This has been done by comparing the result from SCPT to other seismic methods and dynamic parameters converted from “static” geotechnical surveys. SCPT is a relatively new method which has not been used by Sweco or in Sweden to any greater extent and is therefore of interest to be looked in to. By adding two geophones to an ordinary CPT (Cone Penetration Test) equipment as well as including strike plates, hammer and logger system one can log dynamic parameters in addition to the regular parameters logged by a CPT system. This is done by stopping the otherwise continuous CPT survey every meter and striking the strike plates, which are placed under the tracks of the drilling rig. Seismic waves will then travel through the soil down to the geophones and be used to calculate dynamic parameters. For this master thesis a total of 47 geotechnical and geophysical surveys have been considered. The location of these 47 are approximately 7 km north of Norrköping and have been conducted between the years 2016-2017 for the East Link Project. The geotechnical surveys are composed of weight-sounding, ram-sounding and CPT while the geophysical ones are SCPT, refraction-survey and MASW (Multichannel Analysis of Surface Waves). Static elastic parameters have been calculated using the geotechnical survey results according to the Swedish transportation administrations standardized methods. These have then been converted to dynamic parameters with the help of different relationships. When these have been converted they can be compared to SCPT results and other seismic survey methods which also use wave velocity, Poisson’s ratio and density to calculate dynamic elastic parameters. Based on the results from this thesis it can be concluded that the seismic test add-on to a standard CPTu survey is a good method for accessing dynamic modules and it gives extended information of the soil stratigraphy from one single survey point. After the studies and analyses conducted for this thesis it can be concluded that the proposed conversion between static and dynamic young’s modulus using the Alpan curve gives slightly higher values than the ones derived directly from shear waves using SCPT. The other conversion using cone tip resistance to shear wave velocity gives on the other hand slightly lower values than the ones measured with the SCPT. The analysis also indicate similar trends in results between the different seismic methods. These results does however also shows that the used assumptions are somewhat general for accurate comparisons between the methods.

Texte intégralRésumé :
This study investigates the pedagogical applications of scat-singing within the jazz trombone studio. In addition to the obvious ear-training benefits that the student player can gain from this synthesis, the palette of articulation subtleties and overall musically expressive qualities for trombonists can also be greatly enhanced. These commonalities will encompass the pedagogical focus of this document, utilizing performance recordings and publications by prominent jazz artists and writers to document existing teaching strategies as well as develop new concepts. The first section of this document presents an introduction that includes a historical overview of scat-singing, prominent scat-singing instrumentalists, and concepts and current literature. The second section presents selected biographies on Wycliffe Gordon and Bill Watrous, both prominent jazz trombonists who sing as well as play the trombone. The third section investigates jazz articulation, scat-singing articulation, and doodle-tongue articulation and their relevance to this topic. The fourth section explores musically expressive qualities as analyzed in Bill Watrous’ solo transcription of “Body and Soul.” The final section draws conclusions about the pedagogical applications of scat-singing within the jazz trombone studio and summarizes current teaching strategies.

Search engines make vast amounts of information available to Internet users. Two types of tasks users engage in using search engines are closed-ended and open-ended. For closed-ended tasks, individuals have narrow objectives that require finding specific results. For open-ended tasks, individuals only have general objectives that require finding as much relevant information as possible about a topic, which can be difficult when large numbers of both relevant and irrelevant results are returned from a query. This can also leave users in a state of information overload. Some search engines have incorporated information visualization techniques (combining cognitive senses with visual cues that allow for better understanding the information) to facilitate browsing through results in order to reduce information overload. However, there is little research that identifies which visual cues are the most desirable for the presentation of search results. According to information foraging theory, cues that have strong scents will help users find information faster. In this study, we investigate the effects of augmenting visualizations with animation as a powerful scent to help users more easily identify relevant information in search engine results. This study employs cognitive fit theory to study the effect of different information formats on users' performance in completing the two different tasks. Overall, we find evidence that the effectiveness of cues such as animation is task-dependent. For example, we find that visualizations with animation are less effective than a standard textual display for subjects performing closed-ended web search tasks. The results of this study have strong implications for integrating appropriate cues into visualizations in order to help people find information.

Texte intégralRésumé :
I analyzed 1,182 gray wolf (Canis lupus) scats, representing summer diet in 1988-1990, collected from 9 packs in northwest Alaska. Using a linear regression model, I determined the biomass of prey species consumed using relative estimated bulk and frequency of occurrence of prey types in scats. There were no significant differences (P < 0.05) between methods in percent biomass of prey consumed and ranking of prey types. Caribou (Rangifer tarandus), moose (Alces alces), microtines, and birds composed 47.0, 21.9, 10.6, and 13.8%, of prey items, respectively. Ungulates composed 90.1%, birds 6.7%, and microtines 0.5% of biomass consumed. Ungulates composed 3.4%, birds 50.4%, and microtines 38.5% of numbers of individuals consumed. Significant (P < 0.05) observer bias was found in the detection and frequency of prey types in the analysis of 1,052 scats by multiple observers.

Texte intégralRésumé :
Think-aloud protocol is a usability testing method whereby the participant running the usability test on an interface, thinks aloud as a way of giving feedback of the task he/she is performing on the given interface. It is one of the most researched on usability testing methods. It has attracted both praises and criticisms based on the effects it has on the participants or the tests at hand. A recently done study that used simple tasks, aimed at finding out the difference between using think-aloud protocol and not using think-aloud protocol. The study concluded that no notable differences were evident on the number of fixations and the amount of screen areas viewed when using think-aloud protocol and when not using think-aloud protocol.As an extension and follow-up of the recently done study, this study focused on finding the type of tasks that the concurrent think-aloud protocol has effects on. The tasks were chosen based on the information scent concept and eye-tracking methodology was used in collecting the necessary results.The study that involved twenty participants, resulted to some effects of the concurrent think-aloud protocol being noted on the low-scent tasks but not on high-scent tasks. It therefore goes ahead to conclude the tasks onto which concurrent think-aloud protocol would be more effective and the tasks that would be executed more effectively through other usability testing methods other than concurrent think-aloud protocol.

Texte intégralRésumé :
Lo screening è raccomandato per ridurre sia l'incidenza che la mortalità del carcinoma del colon-retto (CCR). Attualmente, molti Paesi organizzano programmi di screening della popolazione basati sull'analisi del sangue occulto nelle feci (FOBT). In Emilia-Romagna (Italia), dal 2005, la versione immunochimica del FOBT (FIT) viene eseguita ogni due anni su persone di età compresa tra 50 e 69 anni. Quindi, la colonscopia viene eseguita sui positivi al FIT.
Sfortunatamente, il FIT mostra un numero elevato di falsi positivi (circa il 65%), principalmente a causa di sanguinamenti di origine non tumorale, che portano a molte colonscopie negative (senza tumori).
L'introduzione di un metodo economico e di facile utilizzo per verificare i positivi FIT migliorerebbe l'efficacia dello screening, riducendo anche i costi per il Servizio Sanitario Nazionale.
Questa tesi mostra i risultati del protocollo di validazione clinica, iniziato nel 2016, di un dispositivo brevettato composto da un array di sensori di gas nanostrutturati. Questo dispositivo, detto SCENT A1, è stato progettato per identificare la presenza di CCR e di lesioni pre-cancesorse mediante la rivelazione di composti organici volatili (VOC) fecali, con un'analisi non invasiva, in vitro e a basso costo. Le feci sono, infatti, contaminate da questi biomarcatori volatili del tumore, prodotti dalla perossidazione cellulare e dalle alterazioni metaboliche delle cellule.
Il protocollo di validazione clinica prevedeva l'analisi, con SCENT A1, di campioni fecali di soggetti FIT positivi allo screening di prevenzione, e l’utilizzo della colonscopia come gold-standard.
Un totale di 398 campioni sono stati analizzati con SCENT A1 e con tecniche avanzate di apprendimento automatico (SVM e PCA).
Inizialmente i campioni sono stati analizzati dividendoli in due macrocategorie a seconda dello stato di salute: sani (individui senza alcun tipo di lesione tumorale) e malati (individui affetti da adenomi ad alto e basso rischio e/o carcinomi) ottenendo una sensibilità e specificità rispettivamente dell'84,1% e dell'82,4%. I VPP e VPN estrapolati sono risultati rispettivamente del 72% e del 91%.
Successivamente tali campioni sono stati analizzati dividendoli in tre categorie: sani, adenomi a basso rischio, adenomi ad alto rischio e carcinomi e ottenendo una sensibilità e specificità rispettivamente dell’80,2% e del 94,4%. I VPP e VPN estrapolati estrapolati sono risultati rispettivamente del 78% e del 95%.
Nel 2020 verrà effettuato uno studio multicentrico per valutare l'accuratezza del test su base demografica.Screening is recommended to reduce both incidence and mortality of colorectal cancer (CRC). Currently, many Countries organize population screening programs based on fecal occult blood test (FOBT). In Emilia-Romagna (Italy), since 2005, FOBT immunochemical version (FIT) is performed every two years on people aged between 50 and 69 years. Then, colonoscopy is carried out on FIT-positives. Unfortunately, FIT shows a high number of false positives (about 65%), mainly due to non-tumoral bleedings, leading to many negative (without tumors) colonoscopies. The use of an economic and easy-to-use method to check FIT-positives would improve effectiveness of the screening, reducing also the costs for National Health Service. This work shows the outcomes of the clinical validation protocol, started in 2016, of a patented device composed by a core of nanostructured gas sensors. This device, SCENT A1, was designed to identify the presence of CRC and pre-cancerous lesions by detecting the fecal volatile organic compounds (VOCs), with a non-invasive, in-vitro and low-cost analysis. Feces are, in fact, affected by tumor volatile biomarkers, produced by cellular peroxidation and metabolic alterations. The clinical validation protocol consisted in the analysis, with SCENT A1, of fecal samples of FIT-positive subjects, using colonoscopy as a gold-standard. A total of 398 samples has been analyzed by means SCENT A1 and with advanced machine learning techniques (PCA e SVM). The samples were initially analyzed by dividing them into two macro-categories according to their health: healthy (individuals without any type of tumor lesion) and sick (individuals with high and low risk adenomas and/or carcinomas) obtaining sensitivity and specificity respectively 84.1% and 82.4%. The extrapolated VPPs and VPNs were 72% and 91% respectively. Subsequently, these samples were analyzed by dividing them into three categories: healthy, low risk adenomas, high risk adenomas and carcinomas and obtaining a sensitivity and specificity of 80.2% and 94.4% respectively. Extrapolated VPPs and VPNs were 78% and 95% respectively. A multicenter study will be performed in 2020, to assess the accuracy of the test on a population basis.
