O objetivo desta dissertação é de apresentar que existe forte relação entre passar no teste de marca e ser capaz de entender representações. Para isso se inicia formando uma base para a discussão da consciência, chegando a conclusão de que a consciência é um problema biológico e como tal deve ser respondido por meio da Biologia. Tendo concluído que a capacidade de se reconhecer (self-recognition) é uma das características da consciência, apresenta-se o teste de marca, faz-se a sua defesa chegando a conclusão de que ele é um teste capaz de apontar se o animal é capaz ou não se de reconhecer por eliminação de qualquer outro tipo de resultado. Por fim, apresenta-se a ligação entre passar no teste de marca e ser capaz de entender representações, colocando a capacidade de se reconhecer como uma prova dessa capacidadeThe main goal of this dissertation is to show that exist a strong relationship between have a positive result in the mark test and be capable of understand representations. For it, we began building a base for the discussion of consciousness, concluding that consciousness is a biological issue and for it need to be answered by Biology. We concluded that the capacity of self-recognition is one of features of consciousness and showing that the mark test is capable to show if the animal is or not capable of self-recognition by elimination of any another kind of result. In the end, we show a bond between have a positive result in the mark test and be able to understand representations, putting the capability of self-recognition as a prove of it

Full textAbstract:
Les méthionine sulfoxyde réductases (Msr) permettent de restaurer la fonction des protéines oxydées sur leur résidus Methionine. Dans un premier temps, le mécanisme catalytique de la MsrA et de la MsrB de la protéine PilB de la bactérie pathogène Neisseria meningitidis a été étudié. Les deux classes de Msr, qui sont structuralement différentes, partagent un même mécanisme catalytique en trois étapes avec formation d'un intermédiaire acide sulfénique suivie de la formation d'un pont disulfure intra moléculaire qui est réduit par la thiorédoxine (Trx). Elles présentent en revanche une stéréospécificité de substrat inverse vis-à-vis de la fonction sulfoxyde. Dans un deuxième temps, les trois étapes du mécanisme catalytique de la MsrB ont été caractérisées au niveau cinétique. L'étude du rôle des acides aminés du site actif dans la catalyse, la caractérisation biochimique de l'interaction MsrB-Trx et, enfin, l'étude du rôle du métal coordiné ont également été abordées.

Full textAbstract:
Ad hoc networks are receiving more and more attentions these years due to their flexibility of fast network organization. The challenge for such networks is the design of efficient dynamic routing protocols adaptive to the frequent topology changes. The CCNR lab has invented the MSR (Multipath Source Routing) and BSR (Backup Source Routing) as improvement over the popular DSR. MSR can support multiple paths and to effectively reduce the congestion problems in networks while BSR (Backup Source Routing) can increase the communication reliability.
In this thesis, we have setup an ad-hoc network testbed consisting of IBM laptops equipped with wireless cards. We have coded and implemented the DSR, MSR and BSR algorithms in the Linux Operating System. Systematic tests and measurements of delay, throughput, and loss rate under various indoor and outdoor scenarios (as well as static and mobile) were carried out so that we can study the tradeoffs among these protocols. Based on our experiments, we have proposed, implemented and demonstrated an improved version of the MSR. We have also implemented these protocols in Qualnet, one of the latest simulation languages built for ad-hoc networking.

Full textAbstract:
Distributed storage systems provide fast and reliable access to data by intro- ducing redundancy for stored les. The most common approach of adding re- dundant information is by repetition and erasure codes. Two main processes in a distributed storage system are reconstruction of original le and regenerat- ing a new node. These two processes require bandwidth, which are termed as reconstruction-bandwidth and repair-bandwidth. The current literature treat- s these two processes separately. That is, there are methods to reduce the reconstructing bandwidth without considering the repair-bandwidth, and also there are methods to reduce the repair-bandwidth. We study these two pro- cesses together and try to jointly minimize the reconstruction-bandwidth and repair-bandwidth. We observe a method that has the minimum reconstruction- bandwidth might have large amount of repair-bandwidth and vice versa. We propose codes which minimizes the sum of the repair-bandwidth and reconstruction- bandwidth. The main contribution of this thesis is nding an value of repair locality r (number of nodes connected during node repair) and devising two coding meth- ods in which total bandwidth approximates to be half reduced compared with MSR and MBR when k ! 1 under the condition that 1 6 r 6 k.

A madeira é um material de fonte renovável, porém com grande variabilidade em suas propriedades mecânicas, devendo ser adequadamente avaliadas e caraderizadas para o correto uso. Uma forma de avaliar estas propriedades é através de ensaios não destrutivos, que não danificam o material. Dentre os vários métodos de classificação destaca-se a classificação mecânica por tensões (MSR), a qual é um efetivo sistema de classificação e avaliação de peças estruturais de madeira, devido sua alta produtividade, podendo todas as peças produzidas serem avaliadas e certificadas. O processo de classificação por meio de ensaios não destrutivos, objetiva determinar os valores do modulo de elasticidade (MOE) e sua correlação com os módulos de resistência a flexão(MOR). A alta produção anual de peças estruturais do gênero pínus spp no Brasil e o conhecimento tecnológico de suas propriedades, tomará sua utilização viável na construção civil em maior escala. Este trabalho avalia a influência da velocidade de ensaio e a intensidade da carga aplicada, nos valores do módulo dinâmico, correlacionando este com os módulos de elasticidade estático e o modulo de resistência à flexão, considerando a classificação visual das peças ensaiadas. Os resultados mostram que a espécie pinus spp deve ser classificada visualmente e mecanicamente para o correto uso estruturalWood is a material of renewable source, however with great variability in their mechanical properties and must becharaderized for it\'s corred use and in arder to determine these properties using non-destrudive tests. Among this tests, stands out the Machine Stress Rating (MSR), which is a effedive system of grading and assessment of strudurallumber, due their high produdivity, ali being able to the produced pieces be assessed and certifled. The process of grading by means of non-destrudive test, objedive to determine the values of MOE and correlate them with MOR values. The annual high production of strudural piaces of pinus spp in Brazil, with the technologic knowledge of their properties, made their utilization feasible in the civil construdion in great scale. This work propose the study of mechanical stress grading for this specie, correlating the values of the dynamic modulus obtained in the MSR, analysing the influence of the speed and test and the intensity of the force applied, with the static modulus and the modulus of rupture. The results showed that in order to use pinus spp to structural purpose the lumber must be visually and mechanically graded.

Full textAbstract:
Thesis advisor: Clare O'ConnorAs organisms get older, the proteins in their cells also age, and as this happens, the amino acids that make up these proteins may become chemically modified and begin to lose their integrity. One example of an age-related modification occurs when the amino acid residue methionine is oxidized by a reactive oxygen species to methionine sulfoxide. Methionine sulfoxide reductase is an enzyme that repairs this damage to the protein by catalyzing a reaction that reduces methionine sulfoxide back to methionine. The fission yeast Schizosachharomyces pombe was used as the experimental model to study methionine sulfoxide reductase in vivo, taking advantage of the variety of tools available with which to study the organism. In S. pombe there are two genes encoding methionine reductase activities, msrA and msrB. The first goal of this project was to construct yeast strains in which the endogenous msrA and msrB genes had been inactivated. This was accomplished via homologous recombination reactions in which the msr genes were replaced with a selectable marker for biosynthesis of uracil (ura4+). After the construction and verification of the two knockout strains, the sensitivities of the strains to reactive oxygen species were tested. Both strains showed reduced resistance to oxidative stress. Future experiments will include more detailed analyses of the abilities of the strains to survive oxidative stress. Finally, the two knockout strains of yeast will be mated with one another in order to produce a double msr knockout, in order to examine the effects of a complete lack of methionine sulfoxide reductase activity on the organism

Mawer, S. J. "Corporate to management social responsibility : extending CSR to MSR guided by Mary Parker Follett." Thesis, University of Salford, 2016. http://usir.salford.ac.uk/38956/.
Full textAbstract:
This research extends the concept of corporate social responsibility (CSR) by proposing that it should be operationalised as a management obligation and redefined as management social responsibility: MSR. The contribution of this research comprises two strands. First it addresses the practicalities for managers initiating and implementing MSR as an integral managerial duty. The contentiousness of defining CSR is addressed by applying a conceptual framework based on an analysis of the works of social scientist and management theorist, Mary Parker Follett (1868 – 1933). Secondly, Follett’s work is synthesised and offered as a starting point to deal with other management demands in theory and practice. The case for MSR invokes the same principles for the elimination of workplace discrimination, not for economic reasons but because it represents socially just and moral business conduct. Follett’s belief that management possesses the capability to advance human welfare was assessed during research in 20 organizations across public, private and non-profit sectors in the UK, France and the USA. Semi-structured interviews with 23 practicing managers, ranging from CEOs to junior managers, produced data on the feasibility of implementing MSR, which was validated by experiences from operationalising other social issues in management. As a result the concept of MSR evolved in which business management is central to a beneficial relationship with all stakeholders The overall qualitative findings of this research indicate that business management attitudes and practice are inclined towards initiating socially responsible business activities. By examining the challenges to managers to accept MSR, their motivation and capability to implement it have been analysed. This analysis informed proposals for a practical framework and professional partnerships to absorb Follett’s philosophies that inform MSR. Subsequent developments can be expected as managers become familiar with MSR, which will contribute to the evolution of theory and practice.

Likheter finns i form av beskrivningen av fördröjningsstrid och nyttjandet av indirekt eld.This essay aims at studying how swedish infantry regulations have changed from the invasion-deterring army of the Cold War to today’s modern expeditional army, but also to show likenesses between these.The essay is based upon two regulations, Infanterireglemente Skyttebataljon 1974 and Markstridsreglemente 6: Manöverbataljon Förhandsutgåva 4 2012, which are compared with an analytical tool constructed from elaborated and operationalized parts of the six basic abilities.The thesis shows that there is a difference concerning the use of indirect method in order to defeat the opponent, and also in the terms of mission tactics. Similarities can be found in the description delaying the opponent and the use of indirect fire.

Eight floor cases were studied and two types of lumber were considered: MSR and VSR lumber where (E is 0.11 and 0.25, respectively. The expected floor vibrational performance of MSR versus VSR lumber floors was evaluated by: 1) the probability that the fundamental frequency is less than 10 Hz and 2) the ratio of the first percentile of predicted fundamental frequency of MSR to VSR lumber.Master of Engineering

Full textAbstract:
L'efflux des macrolides chez les streptocoques, identifié comme phénotype M, est l'un des deux plus prévalent; mécanismes de résistance à ces antibiotiques très largement utilisés. Il est décrit comme impliquant deux déterminant; protéiques qui sont codés par un opéron toujours présent sur les structures génétiques disséminant la résistance. L'un de ces deux déterminants est une protéine de la superfamille MF (Membrane Facilitator) avec douze segments transmembranaires prédits. L'autre est une protéine ABC (ATP-Binding Cassette) bi-domaine dépourvue de segmemt transmembranaire, dont nous avons étudié ici les propriétés chez Escherichia coli afin de cerner son rôle dans la résistance. Dans ce travail, nous avons montré que la protéine ABC désignée ci-après Msr(D) peut conférer seule la résistance chez E. Coli alors que la protéine MFS donne un faible niveau de résistance qui est dirigé seulement contre l'érythromycine L'élévation combinée des niveaux de résistance à l'érythromycine et à l'azithromycine quand les deux protéines son présentes a démontré une synergie suggérant que Msr(D) pourrait faciliter l'action de la protéine MFS dans l'efflux de; macrolides. Nous avons validé l'hypothèse d'une interaction moléculaire entre les deux polypeptides par des approche; génétiques, biochimiques, et aussi grâce à la microscopie de fluorescence. C'est la première fois qu'-est démontrée une coopération fonctionnelle entre un composant ABC et un transporteur MFS; l'implication directe ou indirecte de Msr(D) dans le processus d'efflux restant à préciserMacrolide efflux among streptococci, identified as M phenotype, is one of the two most prevalent mechanisms of résistance to these widely used antibiotics. It is described as involving two protein determinants coded by an operon always present in the genetic structures disseminating the resistance. One of the two determinants is a protein belonging to the MF (Membrane Facilitator) superfamily and having twelve predicted transmembrane segments. The other is a dual ABC (ATP-Binding Cassette) protein devoid of any transmembrane segment, whose properties are here studied in Escherichia coli to decipher its role in the resistance. In this work, we have showed that the ABC protein, designated hereafter Msr(D), is able to confer the résistance traits o the M phenotype in E. Coli while the MFS protein gives a low-level resistance that is directed only against erythromycin The combined increase in resistance levels toward erythromycin and azithromycin when both proteins are présent has demonstrated a synergistic effect suggesting that Msr(D) would facilitate the action of the MFS protein in the macrolide efflux. We have validated the hypothesis of a molecular interaction between the two polypeptides by using genetic and biochemical approaches, and also fluorescence microscopy. To the best of our knowledge, this is the first reported example of a functional cooperation between an ABC component and a MFS transporter; the direct or indirect embroilment of Msr(D) in the efflux process is still to be clarified

Nowadays there is research into molten salt reactors. The use of chlorine-based salts, which would be more available than known fluoride salts, is envisaged. The subject of research is not only the chemical and physical properties of chloride salts, but also their behavior in the neutron field and the influence of neutron balance inside the reactor. Many properties can also be determined using calculations that draw information from scientific nuclear libraries (endf). The purpose of this work is to compare important nuclear libraries with each other, and also to compare the reaction rates calculated from the library data with the reaction rates obtained by self-measurement. The preview will include a description of the necessary activities associated with the preparation of measurements, instructions for compiling the computer program NJOY and the process of the measurement itself. At the end of the work will be summarized the results and statements of which nuclear library is the closest in its values to the results of experiments.

Full textAbstract:
Un réacteur à sels fondus (MSR pour Molten Salt Reactor) est un type de réacteur nucléaire de 4ème génération dans lequel le combustible est liquide, sous forme de sel à haute température, et sert également de caloporteur. Cette spécificité a deux impacts principaux : un fort coefficient de contre-réactivité par densité, et le transport des précurseurs de neutrons retardés par le sel combustible.Ces deux aspects nécessitent d'adapter les codes de calcul existants pour l'étude des MSRs. Au CEA, un outil couplé combinant le code neutronique déterministe APOLLO3® et le code de CFD TrioCFD est développé. Les travaux de thèse portent sur l'étude des fluctuations turbulentes dans un cœur de MSR en utilisant l'outil couplé APOLLLO3®-TrioCFD.Dans un premier temps, une phase de validation de l'outil couplé porte sur la modélisation du premier MSR historique, l'Aircraft Reactor Experiment (ARE), sur lequel de nombreuses expériences ont été réalisées et documentées. La reproduction d'expériences sur l'ARE avec un modèle numérique permet ainsi une première prise en main et une validation du code par comparaisons calculs-mesures.Dans un deuxième temps, l'outil couplé est utilisé pour modéliser le concept Molten Salt Fast Reactor (MSFR), développé depuis une vingtaine d'années d'abord au CNRS, puis au sein d’une coopération européenne. Le MSFR présentant une cuve toroïdale dans laquelle circule librement un écoulement fortement turbulent de sel combustible, les premières modélisations sont uniquement thermohydrauliques, afin de réaliser des simulations CFD (RANS et LES) bien résolues du MSFR en fonctionnement nominal. Ces modélisations permettent d'obtenir des premières estimations des fluctuations de puissance dans le cœur.Le système couplé neutronique – thermohydraulique est finalement étudié, afin d'analyser les impacts respectifs de chacune des physiques, et d'obtenir des résultats précis sur l'amplitude et la fréquence des fluctuations de température et de puissance dans le cœur du MSFRA molten salt reactor (MSR) is a GEN-IV nuclear reactor type where a liquid, high-temperature salt acts as both the fuel and the primary coolant. This characteristic has two main impacts : a strong density feedback and the delayed neutron precursors transport with the fuel salt.These two aspects require adapting the calculation codes used for nuclear reactor studies. In CEA, a coupled code was developed for MSRs studies, combining the deterministic neutronics code APOLLO3® and the CFD code TrioCFD. The objective of the PhD is to study the turbulent fluctuations in MSRs, using the coupled tool APOLLO3®-TrioCFD.In a first step, a validation step of the coupled tool was performed on the first MSR ever built, the Aircraft Reactor Experiment (ARE). Numerous experiments have been performed and documented on the ARE, which enabled comparisons between the experimental results and the simulations performed on a numerical model of the ARE.In a second step, the coupled tool was used to model the Molten Salt Fast Reactor (MSFR) concept, developed for twenty years in CNRS first, then within a European consortium. The MSFR possesses a toroidal core shape where a highly turbulent fuel salt flows. The first calculations performed on the MSFR were purely CFD (RANS and LES turbulence models), in order to resolve accurately the thermal-hydraulics model of the steady-state flow of the reactor. These first calculations also lead to early estimates of the power fluctuations in the core.Eventually the coupled neutronics – thermal-hydraulics system was studied, in order to analyse the respective impacts of each physics. Precise estimates of the temperature and power fluctuations in the MSFR core were obtained

Full textAbstract:
During the period 1990–2013 the Swedish Armed Forces made a number of organisational and material changes. This raises the question of whether these changes also led to tactical adaptations, and if so, if there is a correlation between those adopted in higher and lower levels of field manuals. The purpose of this thesis is to study adaptations in field manuals of Swedish army tactics during 1990–2013. The study also aims to investigate the level of correlation between lower and higher level field manuals. Marcus’ and Farrell’s research on military adaptation and bottom-up change sets the thesis’s theoretical framework. The method used includes a comparative and qualitative text analysis. The study’s result indicates that adaptations in Swedish field manuals show a tendency to decrease the role of artillery support, and increase the role of offensive operations. The results also show a correlation between adaptations made in higher and lower levels of field manuals. The results cannot establish a causal link between the adaptations identified and Marcus’ and Farrell’s research, they do however correlate with their theories. This thesis recommends further studies of the reasons behind the adaptations regarding the use of artillery, as well as the reasons behind the adaptations identified.

Interpretation of Mundell-Fleming (M-F) model is very similar to IS -- LM model. The main difference is that M-F model is based on an assumption of small open economy. This openness is making this model more realistic then IS -- LM model. These assumptions are suitable for Czech economy. In this thesis, model is estimated and interpreted. The most important is an application to Czech economy concerning the period 2002 - 2010. There are ex post and ex ante predictions based on the estimated reduced form of the model. The ex post forecast is used for the purpose of evaluating whether the model is suitable for the prediction. After finding relevant suitability, prediction of endogenous variables is performed in the following four seasons.

Full textAbstract:
A programme of research has now been completed in the College of
Aeronautics (CoA) at Cranfield University to investigate the use of a
Modified Stepwise Regression (MSR) procedure. The technique was
applied to data obtained from a small BAe Hawk aircraft model flown in
a dynamic wind tunnel facility in order to try to estimate the
aerodynamic stability and control derivatives of the model.
A variety of preliminary experiments were performed to enable the
static stability of the Hawk model to be evaluated and estimates for a
limited number of aerodynamic derivatives were obtained. The initial
experiments also allowed data acquisition and processing systems to be
developed. Experience of flying and controlling the model in the wind
tunnel was gained.
The MSR technique was implemented in the form of a FORTRAN 77
software program. Computer simulations of both the full scale Hawk
aircraft and scaled wind tunnel model were written. MSR was found to
produce perfect derivative estimates when using noise-free data
produced by the aircraft simulations.
Various mathematical models were produced to represent the reduced
order small perturbation equations of motion for the Hawk in the wind
tunnel. Different methods for re-constructing the perturbation
variables were implemented. Although the MSR procedure did not perform
optimally with experimental data, some insight into both the MSR method
and the practical difficulties associated with using a small dynamic
rig has been gained.

Full textAbstract:
Magnetospirillum gryphiswaldense MSR-1 is one of a number of species to have a genetic system enabling the biomineralisation of iron in c. 40 linearly arranged organelles within its cell. These magnetosomes are believed to be selectively advantageous to cells as a biological compass that helps to minimise the search for nutrients from a three dimensional environment to a one dimensional environment. The gene, mamK, is part of the genetic system involved in the production of magnetosomes and encodes an amino acid sequence with homology to actin and bacterial cell cycle proteins, such as MreB, ParM and FtsA. Results discussed in this thesis outline in vitro characterisation of recombinant Magnetospirillum gryphiswaldense MSR-1 MamK. MamK was expressed in Escherichia coli with and without an N-terminal His-tag and/or a C-terminal GFP domain or a C-terminal cysteine mutation. In all cases, inclusion bodies were formed. MamK was purified from inclusion bodies and resolubilised. Purified MamK was found to self-associate, as indicted by light-scattering assays, in the presence of divalent cations. In contrast to actin and some other bacterial actin-like proteins polymerisation did not appear to require the presence of NTP; however, ATP and GTP was required for purification by ion exchange column chromatography. Polymerisation did not result in a detectable change in tryptophan fluorescence. Depolymerisation was not readily induced by dilution, but slow depolymerisation occurred in the presence of EGTA, as judged by a decrease in light scattering. Microscopy studies showed that formation of large two-dimensional sheets. These results are consistent with in vivo microscopic studies of MamK where polymerisation has been observed.

The two classes of Msrs conversely present an opposite stereoselectivity towards the sulfoxide function. In the second part, the three steps of the MsrBs catalytic mechanism have been kinetically characterized. The study of the role of the catalytic amino acid, the characterisation of the MsrB-Trx interaction and, the study of the role of the coordinated metal have also been investigated

Les travaux de recherche traités dans cette thèse s’appuient sur l’expertise des actionsmenées entre l’Agence spatiale européenne (ESA), l’industrie Thales Alenia Space (TAS) et le laboratoirede l’Intégration du Matériau au Système (IMS) qui développent de nouvelles générations d’unités intégréesde guidage, navigation et pilotage (GNC) avec une fonction de détection des défauts et de tolérance desdéfauts. La mission de référence retenue dans cette thèse est la mission de retour d’échantillons martiens(Mars Sample Return, MSR) de l’ESA. Ce travail se concentre sur la séquence terminale du rendez-vous dela mission MSR qui correspond aux dernières centaines de mètres jusqu’à la capture. Le véhicule chasseurest l’orbiteur MSR (chasseur), alors que la cible passive est un conteneur sphérique. L’objectif au niveaude contrôle est de réaliser la capture avec une précision inférieure à quelques centimètres. Les travaux derecherche traités dans cette thèse s’intéressent au développement des approches sur base de modèle de détectionet d’isolation des défauts (FDI) et de commande tolérante aux défaillances (FTC), qui pourraientaugmenter d’une manière significative l’autonomie opérationnelle et fonctionnelle du chasseur pendant lerendez-vous et, d’une manière plus générale, d’un vaisseau spatial impliqué dans des missions située dansl’espace lointain. Dès lors que la redondance existe dans les capteurs et que les roues de réaction ne sontpas utilisées durant la phase de rendez-vous, le travail présenté dans cette thèse est orienté seulementvers les systèmes de propulsion par tuyères. Les défaillances examinées ont été définies conformément auxexigences de l’ESA et de TAS et suivant leurs expériences. Les approches FDI/FTC présentées s’appuientsur la redondance de capteurs, la redirection de contrôle et sur les méthodes de réallocation de contrôle,ainsi que le FDI hiérarchique, y compris les approches à base de signaux au niveau de capteurs, les approchesà base de modèle de détection/localisation de défauts de propulseur et la surveillance de sécuritéde trajectoire. Utilisant un simulateur industriel de haute-fidélité, les indices de performance et de fiabilitéFDI, qui ont été soigneusement choisis accompagnés des campagnes de simulation de robustesse/sensibilitéMonte Carlo, démontrent la viabilité des approches proposéesThe work addressed in this thesis draws expertise from actions undertaken between the EuropeanSpace Agency (ESA), the industry Thales Alenia Space (TAS) and the IMS laboratory (laboratoirede l’Intégration du Matériau au Système) which develop new generations of integrated Guidance, Navigationand Control (GNC) units with fault detection and tolerance capabilities. The reference mission isthe ESA’s Mars Sample Return (MSR) mission. The presented work focuses on the terminal rendezvoussequence of the MSR mission which corresponds to the last few hundred meters until the capture. Thechaser vehicle is the MSR Orbiter, while the passive target is a diameter spherical container. The objectiveat control level is a capture achievement with an accuracy better than a few centimeter. The research workaddressed in this thesis is concerned by the development of model-based Fault Detection and Isolation(FDI) and Fault Tolerant Control (FTC) approaches that could significantly increase the operational andfunctional autonomy of the chaser during rendezvous, and more generally, of spacecraft involved in deepspace missions. Since redundancy exist in the sensors and since the reaction wheels are not used duringthe rendezvous phase, the work presented in this thesis focuses only on the thruster-based propulsionsystem. The investigated faults have been defined in accordance with ESA and TAS requirements andfollowing their experiences. The presented FDI/FTC approaches relies on hardware redundancy in sensors,control redirection and control re-allocation methods and a hierarchical FDI including signal-basedapproaches at sensor level, model-based approaches for thruster fault detection/isolation and trajectorysafety monitoring. Carefully selected performance and reliability indices together with Monte Carlo simulationcampaigns, using a high-fidelity industrial simulator, demonstrate the viability of the proposedapproaches

Riversleigh, World Heritage Property, located in North-western Queensland, Australia, contains over 200 fossil bearing localities from the Oligo-Miocene. The study presented here aims at finding new methods to improve the accuracy of palaeoecological and biochronological studies and describe the palaeoenvironmental and chronological settings of the Riversleigh fossil deposits. One of the methods developed in this thesis, Minimum Sample Richness (MSR), determines the minimum number of species that must be present in a fauna to allow meaningful comparisons using multivariate analyses. Using MSR, several Riversleigh localities were selected for a palaeoecological study using the cenogram method to determine the palaeoenvironment during the Oligo-Miocene. Finally, the Numerical ages method was used to refine the relative ages of the Riversleigh localities and a re-diagnosis of the Riversleigh Systems is proposed.

Full textAbstract:
Nondestructive evaluation of the structural integrity of shaft and tunnel concrete linings is the focus of this thesis. A nondestructive testing system was assembled based on the principle of miniature seismic reflection (MSR). The MSR system consists of spherical tip impactors and a pair of vertical and tangential displacement transducers. Mechanical impact causes generation of stress P- and S-waves in the test object. The elastic waveforms undergo multiple reflections between the top and bottom of the testing layer. The surface displacements are captured by a vertical and tangential displacement transducer. The signals are transformed from time domain waveforms to frequency spectra. The vertical displacement transducer is sensitive to normal surface displacements and the highest amplitude peak on the computed frequency spectrum is related to the resonance of the P-wave between the top and the bottom layer. Similarly, the tangential displacement transducer is sensitive to the horizontal surface displacements, and the maximum peak value in the generated frequency spectrum corresponds to the resonance of the S-wave between the two layers of the testing object. Thus, knowing the thickness of the given layer, as well as the measured frequencies, allows P- and S-wave velocities to be calculated. Alternatively, if the thickness is unknown, the time-distance graph of the primary surface wave arrivals can be used to calculate the P-wave velocities and, subsequently, the thickness of the layer. The MSR response depends on the material properties of the testing object. The elastic wave velocities can be used to calculate directly the dynamic elastic properties of the test object. In this study, simulated fractures and steel reinforcement bars were detected and located using the reflected P-waves. In addition, the changes in elastic properties of various types of concrete mixes were monitored for a 28-day curing period. The MSR elastic constants were then compared with dyn

Les réacteurs nucléaires de 4ème génération devront permettre une utilisation optimisée desressources naturelles. Les travaux réalisés durant cette thèse se placent ainsi dans le cadre del'étude du potentiel de déploiement d'un tel réacteur : le MSFR (Molten Salt Fast Reactor), réacteurà sels fondus à spectre neutronique rapide dans une configuration innovante et encore peuétudiée. Comme un excellent niveau de sûreté est une condition nécessaire pour le déploiementde l'énergie nucléaire, il est important de soulever la question de la sûreté de ce type de réacteurdès les premières phases de sa conception.Le MSFR a fait l'objet d'études comparatives des outils de simulations numériques dans lecadre d'un benchmark neutronique au sein du projet européen EVOL. La définition et l'analysedu benchmark neutronique statique et en évolution ont été réalisées pendant cette thèse. Lescomparaisons des différentes grandeurs physiques ont permis de conclure à un bon accord entreles différents codes et méthodes utilisés par les partenaires du projet, et ont mis en avant l'influencedu choix des bases de données nucléaires. Dans l'objectif de l'étude de sûreté du MSFR,la puissance résiduelle a aussi été étudiée en détails. Un outil de calcul de chaleur résiduellea été développé et validé, permettant ainsi d'évaluer la puissance résiduelle précise du MSFR.Les sources de chaleur de chaque localisation contenant des produits radioactifs ont alors étéquantifiées. Ceci a permis de conclure que le sel combustible et l'unité de bullage constituent lessources majeures de puissance résiduelle.Nous avons initié un travail sur la méthodologie de l'étude de sûreté. Les principes fondamentauxde sûreté sont directement transposables au MSFR, mais leurs applications concrètes nele sont pas. En effet, la spécificité du design, due à l'état liquide du combustible et aux systèmesde retraitement associés au réacteur, ainsi que l'état embryonnaire du design, font qu'un travailpréliminaire de transposition des éléments de sûreté a dû être réalisé. Ce travail a conduit entreautres à dresser une liste d'accidents propres au MSFR. Enfin, nous avons pu mener des étudesphysiques préliminaires sur les conséquences possibles de certains de ces accidents, qui serontutilisées comme base pour des études plus approfondies avec des outils plus sophistiqués.

Full textAbstract:
Les méthionines sulfoxyde réductases (Msr) sont impliquées dans la réparation des protéines. MsrA et MsrB sont ubiquitaires et réduisent les méthionines sulfoxydes en méthionines. Chez les bactéries, MsrA et MsrB sont localisées dans le cytoplasme et sont impliquées dans la résistance au stress oxydant. Durant ma thèse, j'ai étudié le rôle du système MsrA/B dans la physiologie d'Escherichia coli. Mon travail a porté sur l'étude de la recombinase A (RecA) comme cible du système MsrA/B. RecA joue un rôle central dans la réparation de l'ADN via ses fonctions principales : la recombinaison homologue, l'induction de la réponse SOS et l'induction de la mutagénèse SOS. J’ai pu établir un lien génétique entre le système MsrA/B et RecA. L'étude révèle que l'absence des Msr affecte la fonction de recombinaison homologue de RecA. J'ai montré que RecA oxydée perd sa capacité à former des filaments sur l’ADN, à hydrolyser de l’ATP et à effectuer l’échange de brin. De manière intéressante, la réparation de RecA oxydée par le système MsrA/B permet de restituer ses fonctions. D'autres analyses ont révélé que le résidu Met35 est important pour l’activité de RecA. Ces résultats m'ont permis de proposer un modèle dans lequel l'état d'oxydation des Met de RecA modulent son activité. Un autre pan de mon travail a permis la caractérisation d’une Msr périplasmique : MsrP. J'ai montré que MsrP est importante lors d’un stress HOCl et que son expression est induite lors d’un tel stress via le système à deux composantes YedVW. La kinase YedV possédant plusieurs Met au sein de son domaine senseur, j'ai proposé un modèle dans lequel l'activation de YedV se ferait via l'oxydation de ses MetMethionine sulfoxide reductase (Msr) are involved in proteins repair. MsrA and MsrB are ubiquitous enzymes which reduce methionine sulfoxide into methionine. In bacteria, MsrA and MsrB are localized in the cytoplasm and are involved in the resistance to oxidative stress. During my PhD, I investigated the role of the MsrA/B system in the physiology of the Escherichia coli. My work was devoted to the study of the recombinase A (RecA) as the target of MsrA/B system. RecA plays a central role in DNA repair via its main functions: homologous recombination, induction of the SOS response and the induction of the SOS mutagenesis. I was able to establish a genetic link between the MsrA/B system and RecA. My study shows that the absence of Msr affects the homologous recombination function of RecA. I have shown that RecA oxidized loses its ability to form filaments on DNA, to hydrolyze ATP and perform strand exchange process. Interestingly, repair RecA oxidized by MsrA/B system restores the functions of RecA. Further analysis revealed that the residue Met 35 is important for the activity of RecA. From these results, I proposed a model in which the oxidation of Met and repair MsrA/B is a dynamic system modulating the activity of RecA. Another part of my work allowed the characterization of periplasmic Msr of E. coli: MsrP. I have shown that MsrP is important under HOCl stress and its expression is induced during such stress via the YedVW two components system. The YedV kinase possessing multiple Met in its sensor domain, I proposed a model in which the activation of YedV would be by oxidation of its Met

The thesis is composed of three main parts. The first part is theoretical and I deal here with economic relationships between macroeconomic magnitudes. Second part dedicated to the econometric theory of prognosis follows, in which I deal with different types of prognoses and prediction methods used at present. In the third, practical, part my intended aim is to create the best possible models of relations between fundamental macroeconomic magnitudes, using real Czech economy data, and to make simulation predictions of these magnitudes based on acquired models while utilising scenario analysis. First, I deal with choice of MSE and VAR models. Then follows the estimate of particular models and validation of prognostic capabilities of particular models for static and dynamic simulation. I conclude with elaboration of macroeconomic magnitudes prognosis while using scenario analysis.

Full textAbstract:
Ces travaux de recherche s’inscrivent dans le cadre de la conception de récepteurs multistandard optimisés pouvant traiter des signaux à spécifications hétérogènes. L’idée est d’appliquer l’échantillonnage aléatoire au niveau de l’étage en bande de base d’un récepteur radio logicielle restreinte afin de tirer profit de son pouvoir d’anti-repliement. La nouveauté dans ces travaux est l’étude analytique de la réduction du repliement spectral par l’échantillonnage aléatoire à temps quantifié, candidat favorable à l’implémentation matérielle. Une deuxième contribution concerne aussi l’étude analytique de l’échantillonnage pseudo-aléatoire à temps quantifié (TQ-PRS) dont l’importance réside en sa grande facilité d’implémentation matérielle. Les formulations théoriques ont permis d’estimer l’atténuation des répliques en fonction du facteur de la quantification temporelle et du facteur du sur-échantillonnage. Les mesures de l’atténuation du repliement spectral ont permis de dimensionner l’étage en bande de base d’une architecture de réception multistandard. Le dimensionnement s’intéresse à différentes configurations de l’étage en bande de base régies par les performances du convertisseur analogique numérique (ADC) utilisé.Les travaux de recherche ont démontré que l’application du TQ-PRS au niveau de l’ADC mène soit à une réduction de l’ordre du filtre anti-repliement soit à une réduction de la fréquence d’échantillonnage. Un bilan global de la consommation de puissance a permis un gain de 30% de la consommation de l’étage en bande de base analogique. En tenant compte du générateur de l’horloge TQ-PRS et de l’étage de sélection numérique du canal, ce gain devient 25%The work presented in this Ph.D. dissertation deals with the design of multistandard radio receivers that process signals with heterogeneous specifications. The originality of these research activities comes from the application of random sampling at the baseband stage of a software defined radio receiver. The purpose behind the choice of random sampling is to take advantage of its alias-free feature. The originality of this work is the analytic proof of the alias attenuation feature of the time quantized random sampling, the implementation version of the random sampling. A second contribution concerns also the analytic study of the simplest implementation version of the random sampling, the time quantized pseudo-random sampling (TQ-PRS). Theoretical formulas allow the estimation of the alias attenuation in terms of time quantization factor and oversampling ratio. Alias attenuation measurement permits to design the baseband stage of the proposed multistandard radio receiver architecture. The design concerns different configuration of the baseband stage according to the performances of the used analog-to-digital converters (ADC). The TQPRS allows decreasing the anti-aliasing filter order or the sampling frequency. The design of the baseband stage reveals a difference on the choice of the time quantization factor for each standard. The power consumption budget analysis demonstrates a power consumption gain of 30% regarding the power consumption of the analog baseband stage. This gain becomes 27.5% when the TQ-PRS clock and the digital canal selection stages are considered

When performing an analysis of the evolution of software quality and software metrics,there is a need to get access to as many versions of the source code as possible. There isa lack of research on how data or source code can be extracted from the source controlmanagement system Git. This thesis explores different possibilities to resolve thisproblem. Lately, there has been a boom in usage of the version control system Git. Githubalone hosts about 6,100,000 projects. Some well known projects and organizations thatuse Git are Linux, WordPress, and Facebook. Even with these figures and clients, thereare very few tools able to perform data extraction from Git repositories. A pre-studyshowed that there is a lack of standardization on how to share mining results, and themethods used to obtain them. There are several tools available for older version control systems, such as concurrentversions system (CVS), but few for Git. The examined repository mining applicationsfor Git are either poorly documented; or were built to be very purpose-specific to theproject for which they were designed. This thesis compiles a list of general issues encountered when using repositorymining as a tool for data gathering. A selection of existing repository mining tools wereevaluated towards a set of prerequisite criteria. The end result of this evaluation is thecreation of a new repository mining tool called Doris. This tool also includes a smallcode metrics analysis library to show how it can be extended.

The master ‘s thesis deals with the studying behavior of nuclear reactors cooled by liquid salts and with application of liquid salts for IV. Generation of nuclear reactors. For the use of liquid salts, it’s necessary to change the concept of the structure of nuclear reactors. There are new ways to use new fuel in a liquid state. Each salt compound or a set thereof is original in its nature. Therefore, it is necessary to consider a suitable compound for the purposes employed. These points are discussed in the theoretical part. The thesis examines particularly chloride salts, with which there is not much experience. The practical part monitors and verifies the nuclear properties of chloride salts, in our case it is a solid-state chloride sodium chloride’s compound. In addition to the experimental measurement, the MCNP simulation program is used also.

This is a qualitative literature analysis aimed at investigating elements of spirituality within the mindfulness practice of MBSR. This is done by looking at different definitions of spirituality, religiosity and mindfulness. I also look at the origins of mindfulness in the MBSR program and compare it to its contemporary religious counterpart to look for which similarities do or don’t exist. I consider the historical and current uses of these concepts to create a necessary background and theory. The study shows that mindfulness and related concepts are often not described in a satisfactory way within literature which creates problems in research. The founder of the MBSR method, Jon Kabat-Zinn, wanted to re-conceptualize Buddhist concepts in a secular context. But the actual inclusion of these elements depends largely on which definitions are used, and on the specific practice situation and instructor and partly on the participants’ own sense of spirituality. I discuss the use of mindfulness in secular and New age type businesses and bring up earlier criticism of mindfulness both from scientists and Buddhists. I also discuss spirituality in a secular context and how the MBSR program can be used by New age spiritual seekers and to fill people’s need for meaning and sense of coherence (SOC) in an individualistic society which is increasingly abandoning traditional religions.

Consciousness, as a biological phenomenon, may consists of states of feeling, sensation or awareness. Specialized behaviour, sophisticated actions of communication, metacognition, social interaction, spatial orientation, the use of mental maps for navigation, and spatial memory, all point to conscious processing in genus other than Homo. This work aims to identify self-awareness states in two different species: using mirror self-recognition tests in Callithrix jacchus, and using self-perception tests in Dinoponera quadriceps. Displays of C. jacchus self-recognition using a mirror, were appraised with two protocols: no mark and with mark. D.quadriceps navigational capability displays during foraging trips to food resource, were appraised considering three different tests categories: (1) free access, (2) blocked by opaque object; and 3) blocked by clear object. Our results show self-perception in both studied species. With marmosets displaying contingency check behaviour to the specular image, self-observation, environmental exploration using the mirror as a tool and little, but significant mark reactions. Tocandiras were able to perceive its own location and to calculate short return paths to the colony after obtaining the food resource in all three types of tests. Here we provide further evidence of conscious states for species other than vertebrates.

O aumento nos rejeitos industriais e a contínua produção de resíduos causam muitas preocupações no âmbito ambiental. Neste contexto, o descarte de pneus usados tem se tornado
um grande problema por conta da pequena atenção que se dá à sua destinação final. Assim sendo, essa pesquisa propõe a produção de uma mistura polimérica com polipropileno (PP), a borracha de etileno-propileno-dieno (EPDM) e o pó de pneu (SRT). A Metodologia de Superfície de Resposta (MSR), coleção de técnicas estatísticas e matemáticas úteis para
desenvolver, melhorar e optimizar processos, foi aplicada à investigação das misturas ternárias. Após o processamento adequado em extrusora de dupla rosca e a moldagem por
injeção, as propriedades mecânicas de resistência à tração e resistência ao impacto foram determinadas e utilizadas como variáveis resposta. Ao mesmo tempo, a microscopia
eletrônica de varredura (MEV) foi usada para a investigação da morfologia das diferentes misturas e melhor interpretação dos resultados. Com as ferramentas estatísticas específicas e
um número mínimo de experimentos foi possível o desenvolvimento de modelos de superfícies de resposta e a otimização das concentrações dos diferentes componentes da
mistura em função do desempenho mecânico e além disso com a modificação da granulometria conseguimos um aumento ainda mais significativo deste desempenho
mecânico.The increase in industrial waste and solid waste production cause many concerns in the environment. In this context, the disposal of used tires has become a major problem because of the little attention given to their final destination. Therefore, this research proposes the production of a polymer blend of polypropylene (PP), rubber of ethylene-propylene-diene (EPDM) and tire dust (SRT). The Response Surface Methodology (RSM), a collection of mathematical and statistical techniques useful for developing, improving and optimizing processes, was applied to the investigation of ternary mixtures. After proper processing on twin screw extrusion and injection molding, the mechanical properties of tensile and impact strength were determined and used as response variables. At the same time, scanning electron microscopy (SEM) was used to investigate the morphology of different blends and better interpretation of results. With specific statistical tools and a minimum number of experiments it was possible to develop models of response surfaces and the optimization of the concentrations of different components of the mixture depending on the mechanical performance and even with the change in particle size could increase even more significant this mechanical performance.

Full textAbstract:
Ces travaux de recherche s’inscrivent dans le cadre de la conception de récepteurs multistandard optimisés pouvant traiter des signaux à spécifications hétérogènes. L’idée est d’appliquer l’échantillonnage aléatoire au niveau de l’étage en bande de base d’un récepteur radio logicielle restreinte afin de tirer profit de son pouvoir d’anti-repliement. La nouveauté dans ces travaux est l’étude analytique de la réduction du repliement spectral par l’échantillonnage aléatoire à temps quantifié, candidat favorable à l’implémentation matérielle. Une deuxième contribution concerne aussi l’étude analytique de l’échantillonnage pseudo-aléatoire à temps quantifié (TQ-PRS) dont l’importance réside en sa grande facilité d’implémentation matérielle. Les formulations théoriques ont permis d’estimer l’atténuation des répliques en fonction du facteur de la quantification temporelle et du facteur du sur-échantillonnage. Les mesures de l’atténuation du repliement spectral ont permis de dimensionner l’étage en bande de base d’une architecture de réception multistandard. Le dimensionnement s’intéresse à différentes configurations de l’étage en bande de base régies par les performances du convertisseur analogique numérique (ADC) utilisé.Les travaux de recherche ont démontré que l’application du TQ-PRS au niveau de l’ADC mène soit à une réduction de l’ordre du filtre anti-repliement soit à une réduction de la fréquence d’échantillonnage. Un bilan global de la consommation de puissance a permis un gain de 30% de la consommation de l’étage en bande de base analogique. En tenant compte du générateur de l’horloge TQ-PRS et de l’étage de sélection numérique du canal, ce gain devient 25%The work presented in this Ph.D. dissertation deals with the design of multistandard radio receivers that process signals with heterogeneous specifications. The originality of these research activities comes from the application of random sampling at the baseband stage of a software defined radio receiver. The purpose behind the choice of random sampling is to take advantage of its alias-free feature. The originality of this work is the analytic proof of the alias attenuation feature of the time quantized random sampling, the implementation version of the random sampling. A second contribution concerns also the analytic study of the simplest implementation version of the random sampling, the time quantized pseudo-random sampling (TQ-PRS). Theoretical formulas allow the estimation of the alias attenuation in terms of time quantization factor and oversampling ratio. Alias attenuation measurement permits to design the baseband stage of the proposed multistandard radio receiver architecture. The design concerns different configuration of the baseband stage according to the performances of the used analog-to-digital converters (ADC). The TQPRS allows decreasing the anti-aliasing filter order or the sampling frequency. The design of the baseband stage reveals a difference on the choice of the time quantization factor for each standard. The power consumption budget analysis demonstrates a power consumption gain of 30% regarding the power consumption of the analog baseband stage. This gain becomes 27.5% when the TQ-PRS clock and the digital canal selection stages are considered

Full textAbstract:
Consumers are often confronted with incomplete product information. In such instances, they can eliminate the product from further consideration due to higher associated uncertainty or ask for more information. Alternatively, they can apply subjective theories about covariation to infer the value of missing attributes. This paper investigates the latter option in the context of sustainability and provides an in-depth exploration of consumers' inference formations. Drawing from rich qualitative data, it offers a conceptualization of the underlying relationships consumers use to infer product sustainability based on other product attributes. The study further assesses whether these findings can be captured in a quantifiable way. To this end, inferred sustainability is conceptualized as a formative second-order construct, thereby depicting the influence of inference-triggering product attributes. (authors' abstract)

Lind, Anders. "High-speed View Matching using Region Descriptors." Thesis, Linköping University, Computer Vision, 2010. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-58843.
Full textAbstract:
This thesis treats topics within the area of object recognition. A real-time view matching method has been developed to compute the transformation between two different images of the same scene. This method uses a color based region detector called MSCR and affine transformations of these regions to create affine-invariant patches that are used as input to the SIFT algorithm. A parallel method to compute the SIFT descriptor has been created with relaxed constraints so that the descriptor size and the number of histogram bins can be adjusted. Additionally, a matching step to deduce correspondences and a parallel RANSAC method have been created to estimate the undergone transformation between these descriptors. To achieve real-time performance, the implementation has been targeted to use the parallel nature of the GPU with CUDA as the programming language. Focus has been put on the architecture of the GPU to find the best way to parallelize the different processing steps. CUDA has also been combined with OpenGL to be able to use the hardware accelerated anisotropic sampling method for affine transformations of regions. Parts of the implementation can also be used individually from either Matlab or by using the provided C++ library directly. The method was also evaluated in terms of accuracy and speed. It was shown that our algorithm has similar or better accuracy at finding correspondences than SIFT when the 3D geometry changes are large but we get a slightly worse result on images with flat surfaces.

Thesis, Uppsala universitet, Institutionen för folkhälso- och vårdvetenskap, 2015. http://urn.kb.se/resolve?urn=urn:nbn:se:uu:diva-270901.
Full textAbstract:
Bakgrund: Vaccinationstäckning är ett av de viktigaste och mest kostnadseffektiva sättet att förbättra den globala folkhälsan. Trots det uppfattas vacciner som osäkert och onödigt av allt fler individer. Försämrad vaccinationstäckning påverkar flockimmuniteten med ökad risk för nya sjukdomsutbrott och epidemier. Syfte: Syftet var att undersöka och sammanställa den vetenskapliga litteraturen om vilka faktorer som påverkar vårdnadshavarnas beslut att vaccinera eller inte vaccinera sina barn mot mässling-påssjuka-röda hund (MPR). Metod: Systematisk litteraturöversikt där totalt tio vetenskapliga artiklar ligger till grund för resultatet. The Health Belief Model har använts som teoretisk utgångspunkt. Resultat: Flera faktorer var viktiga för föräldrars beslut om vaccination. Fem faktorer identifierades som påverkar föräldrar att inte vaccinera sina barn: att föredra naturlig immunisering, rädsla för biverkningar, rädsla för vaccinet, misstro till myndigheter och förebygga sjukdom genom livsstil. Fyra faktorer som påverkar föräldrar att låta vaccinera sina barn identifierades: att undvika sjukdom, värna om flockimmunitet, fördelar överväger nackdelar samt kunskap och information om sjukdomarna och vaccinet. I resultatet identifierades också ett bifynd, att låta barnets immunsystem mogna innan vaccination. Både föräldrar som vaccinerade och inte vaccinerade sina barn tyckte att det fanns för lite information om vaccinet och dess biverkningar. Slutsats: Flera faktorer påverkar föräldrars beslut om vaccination för sina barn mot MPR. Både föräldrar som vaccinerar och inte vaccinerar sina barn tycker informationen om vaccin och dess biverkningar är för knapphändig och svårtillgänglig. Det är viktigt som sjuksköterska att ha kunskap om vilka faktorer som påverkar föräldrars beslut för att kunna bemöta föräldrars oro och bistå med adekvat och evidensbaserad information.Background: Vaccination coverage is one of the most important and cost-effective ways to improve global health. Despite this more and more people feel uncertain about vaccinations. Impaired vaccination coverage affects the herd immunity and leads to an increased risk of disease outbreaks and epidemics. Aim: The aim of this study was to examine which factors influence parents’ decisions regarding vaccination of their children against measles-mumps-rubella (MMR). Method: A systematic review where the result is based on ten scientific articles. The Health Belief Model was used as theoretical framework. Results: Several factors were important for the decision to vaccinate or not. Five factors were identified among parents not vaccinating: to prefer natural immunization, fear of side effects, fear of the vaccine, mistrust in the authorities and prevent disease through lifestyle. While four factors were identified among parents vaccinating: to prevent disease, to protect the herd immunity, the advantages outweigh disadvantages, and knowledge and information about the disease and the vaccine. In addition, the finding, to let the child's immune system mature before vaccination was identified. Both parents who accept vaccination and parents who decline vaccination of their children considered the information about the vaccine inadequate. Conclusion: Several factors influence parents’ decision regarding vaccination of their children against MMR. Both parents who accept vaccination and parents who decline vaccination of their children consider the information about the vaccine and its side effects too scant and difficult to access. It's important that nurses have knowledge about factors that influence parents' decisions in order to respond to their concerns and provide appropriate and evidence-based information.
