Remy, Benjamin. "Generative modeling for weak lensing inverse problems". Electronic Thesis or Diss., université Paris-Saclay, 2023. http://www.theses.fr/2023UPASP163.
Pełny tekst źródłaGravitational lensing, which is the effect of the distortion of distant galaxy images through the influence of massive matter densities in the line of sight, holds significant promise in addressing questions about dark matter and dark energy. It reflects the distribution of total matter of the Universe and is therefore a promising probe for cosmological models. In the case where these distortions are small, we call it the weak gravitational lensing regime and a straightforward mapping exists between the matter distribution projected in the line of sight, called mass-map, and the measured lensing effect. However, when attempting to reconstruct matter mass-maps under conditions involving missing data and high noise corruption, this linear inverse problem becomes ill-posed and may lack a meaningful solution without additional prior knowledge. The main objective of this thesis is to employ recent breakthroughs in the generative modeling literature that enable the modeling of complex distribution in high-dimensional spaces. We propose in particular a novel methodology to solve high-dimensional ill-posed inverse problems, characterizing the full posterior distribution of the problem. By learning the high dimensional prior from cosmological simulations, we demonstrate that we are able to reconstruct high-resolution 2D mass-maps alongside uncertainty quantification. Additionally, we present a new method for cosmic shear estimation based on forward modeling of the observation at the pixel level. This represents a new paradigm for weak lensing measurement as it does not rely on galaxy ellipticities anymore. In particular, we propose to build a hybrid generative and physical hierarchical Bayesian model and demonstrate that we can remove the source of model bias in the estimation of the cosmic shear

Pełny tekst źródłaGravitational lensing, that is the distortion of the images of distant galaxies by intervening massive objects, has been identified as one of the most promising probes to help answer questions relative to the nature of dark matter and dark energy. As the lensing effect is caused by the total matter content, it can directly probe the distribution of the otherwise invisible dark matter. By measuring the shapes of distant galaxies and statistically estimating the deformations caused by gravitational lensing, it is possible to reconstruct the distribution of the intervening mass. This mass-mapping process can be seen as an instance of a linear inverse problem, which can be ill-posed in many situations of interest, especially when mapping the dark matter on small angular scales or in three dimensions. As a result, recovering a meaningful mass-map in these situations is not possible without prior information. In recent years, a class of methods based on a so-called sparse prior has proven remarkably successful at solving similar linear inverse problems in a wide range of fields such as medical imaging or geophysics. The primary goal of this thesis is to apply these sparse regularisation techniques to the gravitational lensing problem in order to build next-generation dark matter mass-mapping tools. We propose in particular new algorithms for the reconstruction of high-resolution 2D mass-maps and 3D mass-maps and demonstrate in both cases the effectiveness of the sparse prior. We also apply the same sparse methodologies to the reconstruction the primordial density fluctuation power spectrum from measurements of the Cosmic Microwave Background which constitutes another notoriously difficult inverse problem. We apply the resulting algorithm to reconstruct the primordial power spectrum using data from the Planck satellite. Finally, we investigate new methodologies for the analysis of cosmological surveys in spherical coordinates. We develop a new wavelet transform for the analysis of scalar fields on the 3D ball. We also conduct a comparison of methods for the 3D analysis of spectroscopic galaxy survey

O resfriamento a vácuo é considerado um método de resfriamento rápido, sendo largamente aplicado em vegetais folhosos, além de ser também empregado para o pré-resfriamento de flores após a colheita. O resfriamento é obtido pela evaporação da água do próprio produto, quando este é submetido a uma baixa pressão em uma câmara hermética. Um dispositivo experimental foi montado para a realização deste trabalho e a aplicação da técnica de resfriamento a vácuo foi avaliada através da realização de três estudos. A influência da taxa de redução de pressão durante o resfriamento a vácuo de cortes de frango cozidos foi investigada no primeiro estudo. Através do controle da taxa de evacuação da câmara de vácuo, por um dispositivo de vazamentos calibrados, a perda de massa foi reduzida em 1,11%. Quando comparado com outros processos de resfriamento a vácuo, onde o controle da taxa de evacuação foi efetuado, o resfriamento a vácuo de cortes de frango cozidos mostrou ser a aplicação mais eficiente quanto à relação decréscimo de temperatura por perda percentual de massa. No segundo estudo foram realizados experimentos com diferentes cortes de carne pré-cozidos, obtendo-se dados que foram utilizados para determinar correlações empíricas entre o produto do coeficiente de transferência de massa e da área total de transferência de massa (kS) com o volume das amostras avaliadas. Os resultados indicaram que a evaporação da água pode ocorrer em todo o volume das amostras, o que é fundamental para a obtenção de resfriamentos homogêneos. A aplicabilidade da técnica para o resfriamento de mexilhões após a etapa de cozimento foi avaliada no terceiro estudo. Os experimentos foram realizados em três diferentes sistemas de resfriamento. Os mexilhões pré-cozidos puderam ser resfriados de 90 a 40ºC em menos de dois minutos. Além disso, os processos de cozimento e de resfriamento podem ser realizados em uma mesma câmara, reduzindo a manipulação do produto. Assim, o resfriamento a vácuo de cortes de carnes cozidos é uma alternativa viável de aplicação industrial, mas que deve ser acompanhada de análises sensoriais do produto resfriado, pois modificações de textura e suculência das carnes foram evidenciadas.

Pełny tekst źródłaThis study aimed to compare the salivary protein content of adolescents presenting active caries lesions with caries-free persons. Twelve adolescents with average age of 15.2 (standard deviation=1.6) years old were divided into three groups according to the caries occurrence: Group CA - participants with at least four active cavitated caries lesions (n = 4), classified as scores 5 and/or 6 according to the International Caries Detection and Assessment System (ICDAS); Group MB - adolescents (n = 4) in which subjects showed at least four cavitated active lesions (ICDAS 5 and 6), group MB (n=4) with at least four active initial caries lesions (scores 1 and/or 2 of ICDAS); and group CO - with subjects with no active caries lesions (n = 4). Proteins from stimulated saliva (20 ?g) were submitted to sodium-dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) in three independent experiments. Densitometric values from fifteen bands of different molecular weights were measured and analyzed with analysis of variance (p<0.05). Mass spectrometry was used to identify and characterize the proteome from electrophoretic bands. Relative quantification consisted in submit to SDS-PAGE salivary protein samples paired by total protein concentration from groups MB and CO. Electrophoretic bands were densitometrically analyzed, and their protein content were quantified with mass spectrometry. Results from SDS-PAGE revealed that four bands of high and low molecular weight from group MB were statistically higher when compared to group CO. Samples from group CA did not show differences when compared to group CO. Mass spectrometry showed the protein content from SDS-PAGE electrophoretic bands. Relative quantitative analysis showed differences among groups in bands of high, middle and low molecular weights, as well in their proteins. This study concludes that there are differences in the proteomic composition of saliva from adolescents with active caries lesions when compared to persons with no active caries lesions, mainly considering initial active caries lesions.

Resumo: Este estudo transversal objetivou investigar a relação entre o estado nutricional, cárie dental, exposição diária ao açúcar e fatores sociais, assim como a presença de biofilme visível em 303 pré-escolares de 3 a 5 anos da cidade de Teresina-PI. A cárie dental foi determinada por meio do critério da Organização Mundial de Saúde (OMS) incluindo lesões iniciais de mancha branca (LMB). O peso e altura corporais foram mensurados e o Índice de massa corporal (IMC) obtido foi plotado em diagrama segundo gênero e faixa etária para obter-se o ranking do percentil segundo o Centers for Disease Control and Prevention (CDC). Os dados de exposição diária ao açúcar (líquido, sólido e total) foram obtidos pelo diário de dieta, usando-se a média de exposição diária de 72 horas. A presença de biofilme dental clinicamente visível nos incisivos superiores foi também registrada. Os fatores comportamentais e socioeconômicos foram coletados por meio de uma entrevista com as mães ou responsáveis pelas crianças. Os dados foram analisados por meio do teste qui quadrado seguido de regressão logística múltipla (? = 0,05, intervalo de confiança = 95%). Os resultados mostraram que 10,6% das crianças eram malnutridas, 17,2% tinham baixo peso, 44,9% apresentaram peso normal, 15,5% tinham sobrepeso e 11,9% eram obesos; 24,8% estavam livres de cárie e 75,2% apresentavam cárie precoce da infância (CPI). A média do ceo-s + LMB foi 10,8 (+ 11,2). Crianças com experiência de cárie apresentaram 0,3 mais chance de serem obesas do que aquelas livres de cárie (p = 0,0049). Da mesma forma, aquelas que consumiam líquidos açucarados mais de 2 vezes por dia apresentaram 2,7 mais chance de serem obesas (p = 0,0339). Nenhuma associação foi encontrada ente cárie e sobrepeso (p = 0,3640) e a presença de biofilme dental (p= 0,3190). Crianças que apresentaram o hábito de dormir com a mamadeira mostraram 2,3 vezes mais chance de terem baixo peso do que aquelas sem esse hábito (p = 0,0174). O gênero feminino apresentou a probabilidade 0,3 vezes maior de serem malnutridas do que o masculino (p = 0,00797). Além disso, pré-escolares com a presença de biofilme dental tiveram 3,1 vezes mais chance de serem malnutridas do que aquelas sem biofilme visível (p = 0,0247). Este estudo mostrou que houve relação entre experiência de cárie, consumo de líquidos açucarados e obesidade. Também mostrou relação entre o uso da mamadeira noturna e baixo peso na infância. Fatores socioeconômicos não foram relacionados ao estado nutricional da criança
Abstract: This cross-sectional study aimed to investigate the relationship among body mass index (BMI), dental caries, sugar exposure and social factors, as well as the presence of visible biofilm in 303 three-to-five-year-old preschoolers in the city of Teresina-PI, Brazil. Dental caries was recorded according to the World Health Organization criteria (WHO) + early caries lesions (ECL). Body weight/height was determined and BMI was calculated. Data regarding the sugar exposure was recorded using the mean exposure of 72-hour recall diet frequency chart. The presence of clinically visible dental biofilm on maxillary incisors was also recorded. Behavioral and social economic status of the study subjects were assessed using an interview applied to the mother. Data were analyzed by chi-square test followed by multiple logistic regression analysis (? = 0.05, confidence interval = 95%). The results showed that 10.6% of the children were malnourished, 17.2% were underweight, 44.9% had health weight, 15.5% were at risk of overweight, and 11.9% were obese; 24.8% were caries free and 75.2% had early childhood caries (ECC). The mean dmfs score was 10.8 (± 11.2). Preschool children with ECC were 0.3 times more likely to be obese than caries free children (p = 0.0049). In the same way, those who consumed liquid sugar more than 2 times a day, were 2.7 times more likely to be obese (p = 0.0339). No association was found between overweight and caries (p=0.3640) and dental biofilm (p= 0.3190). Preschool children who slept with a bottle were 2.3 times more likely to have underweight than children who did not sleep with a bottle (p = 0.0174). Female preschool children were 0.3 times more likely to be malnourished than boys (p = 0.00797). Moreover, preschool children with presence of dental biofilm were 3.1 times more likely to be malnourished than children with absent biofilm (p = 0.0247). In conclusion, our results suggest that preschool children having early childhood caries and a high liquid sugar consumption were more likely to be obese and those who were bottle fed during the night showed a higher chance of having underweight

Pełny tekst źródłaThe study of the cryosphere, which is one of the main active component in the global climate system, including global sea level, represents a major interest in the understanding of the current climatic changes. The polar zones are, at the moment, the world areas where the climatic changes appear in a spectacular way, and this reinforces the necessity of a better understanding of the total and surface mass balance of the ice sheets. Indeed, the Antarctic mass balance (surface and total), is not well known yet and is not correctly represented in current climatic models; this matter of fact contributes to strong uncertainties about future climate projection as well as associated potential contribution on sea level change. As a consequence, the continuation of studies on total and surface mass balance (and future change) in the different Antarctic regions, in response to the actual (and future climate), appears essential. In the framework of the present manuscript, I propose to reduce uncertainties in the Antarctic surface mass balance (SMB) estimates, inducing the possibility to optimize the reconstruction of the accumulation parameter over the continent with atmospheric general circulation (climatic) models and interpolation maps of in situ observations

Pełny tekst źródłaIn biology, mass spectrometry has become an indispensable tool for protein identification. Associated with separation techniques, it can also be used to measure the variation of protein abundance between different samples. However, due to the huge quantity and complexity of the data produced by this kind of analysis, sophisticated and suitable computer programs are needed. My PhD work was to address the different issues related to the processing of nanoLC-MS/MS data, namely the validation of the identification results, and the relative quantification of proteins using approaches based or not on isotopic labeling. The MFPaQ program, two versions of which are presented here, is the main result of this work. Version 3 includes features such as Mascot data validation, generation of non-redundant protein lists and quantification of ICAT analyses. Version 4, which represents a major upgrade of the software, incorporates additional algorithms for quantitative analysis of label-free MS data, as well as for the handling of the 14N/15N and SILAC labeling strategies. This bioinformatic tool has been used for various proteomic studies, some of which are discussed here. In order to meet future IT challenges in proteomics, I undertook later the development of the Prosper software, which is based on an optimized architecture for organizing data, and allows performing cross-queries on all analysed samples. It also constitutes a prototype tool for the development and evaluation of new algorithms

Pełny tekst źródłaENGLISH ABSTRACT: The aim of this assignment is to examine two investigative journalism programmes in South Africa, namely Carte Blanche and SpecialAssignment in order to ascertain whether two South African policing organisations have been subjected to racist stereotyping on these two programmes. Both these programmes are held in high esteem within South African and international media circles. Carte Blanche has won many awards, such as the prestigious eNN African Journalist of the Year Award in 2002. Special Assignment won the equivalent award in 2001. The approaches and styles in revealing the truth by using investigative forms of journalism are however slightly different. Both Carte Blanche and Special Assignment have produced stories from August 2003 to September 2004 that have exposed corruption within the South African policing organisations. Many of the perpetrators within the police force were identified as people of colour. This assignment therefore aims to discover whether racist stereotyping exists in this niche of investigative journalism television programmes. This opens up the possibility for these portrayals to be seen as stereotypical, since the dominant press codes in South Africa stipulates that reference to 'race' in news reporting should only be done where it will contribute significantly to understanding the subject matter or if the reference to the race of the person is particularly applicable. This assignment aims to discover whether racist stereotyping exists in this niche of investigative journalism television programmes. The research method comprised analysing programmes on Carte Blanche and Special Assignment that dealt with the South African policing organisations from August 2003 to September 2004. The original transcripts of the programmes were retrieved from the relevant websites of Carte Blanche and Special Assignment and have also been studied. Sources on media ethics as well as newspaper and magazine articles dealing with the South African policing organisations, crime and corruption were scrutinized in order to provide background information for the study. The analyses of the programmes was complemented by interviews conducted with the investigative journalists at the helm of the two programmes, namely, Ruda Landman from Carte Blanche and Jessica Pitchford from Special Assignment.
AFRIKAANSE OPSOMMING: Die doel van hierdie studie is om twee ondersoekende joernalistiekprogramme in Suid-Afrika, naamlik Carte Blanche en Special Assignment, te ondersoek ten einde vas te stelof die Suid- Afrikaanse polisiëringsorganisasies in dié twee programme aan rassestereotipering onderhewig is. Albei dié programme word hoog geag in Suid-Afrikaanse en internasionale mediakringe. Carte Blanche het reeds verskeie toekennings gewen, soos die toonaangewende eNN Afrikajoernalis van die Jaar Toekenning in 2002. Special Assignment het hierdie toekenning in 2001 gewen. Die benaderings en styl wat tydens die bekendmaking van die waarheid gevolg word deur die toepassing van ondersoekende vorme van joernalistiek verskil egter effe. Sowel Carte Blanche as Special Assignment het van Augustus 2003 tot September 2004 stories opgelewer wat korrupsie in die Suid-Afrikaanse polisiëringsorganisasies aan die kaak gestel het. Baie van die skuldiges in die polisiemag is geïdentifiseer as gekleurde mense. Hierdie studie beoog dus om vas te stel of daar rassestereotipering in hierdie afdeling van televisieprogramme met betrekking tot ondersoekende joernalistiek bestaan. Ondersoekende joernalistiek is ongetwyfeld een van die stimulerendste afdelings van die joernalistiek. Dit is 'n uitgesproke vorm van joernalistiek wat die vermoë het om die samelewing te beïnvloed. Ondersoekende joernalistiek maak gewoonlik misdrywe aan die publiek bekend. Die konsekwente uitbeelding van gekleurde mense op 'n negatiewe wyse sou kon lei tot die inboet van etiese waardes en dus tot rassestereotipering. Die navorsingsmetode het behels dat daar van Augustus 2003 tot September 2004 na programme oor die Suid-Afrikaanse polisiëringsorganisasies op Carte Blanche en Special Assignment gekyk is en dat dit op band opgeneem is. Die oorspronklike transkripsies van die programme is van Carte Blanche en Special Assignment se onderskeie webtuistes verkry en word as bylaes by hierdie studie aangeheg. Bronne oor media-etiek asook koerant- en tydskrifartikels wat oor die Suid-Afrikaanse polisiëringsorganisasies, misdaad en korrupsie handel, is noukeurig nagegaan. 'n Persoonlike onderhoud is met Ruda Landman van Carte Blanche gevoer, en met Jessica Pitchford van Special Assignment is 'n onderhoud per e-pos gevoer. Landman en Pitchford was albei betrokke by die samestelling van die betrokke

Pełny tekst źródłaObesity is one of the most rapid growing illnesses and dental caries is still a common illness by children and youth. The aims of this licentiate thesis were: describe frequency of overweight and obesity from birth to twenty years of age. analyze weight and weight development from birth to adult age. examine prevalence of approximal dental caries by teenagers fifteen years of age comparing to their age-specific BMI (isoBMI). examine early snacking habits and dental caries at the age of fifteen. The investigations have a population based longitudinal design and the analyses are based on data from 671 children followed from birth to 20 years of age. Information about weight and height were collected from health records at child health centers and school health care. At 20 years of age, weight and height measurements were performed by one of the authors. Data were also selected from caries examinations, interviews and questionnaires when the children were 1 and 3 years of age and from the children’s bitewing radiographs at 15 years of age. The result showed an association between overweight/obesity at 20 years and overweight/obesity at 5½ and 15 years. However, 70% of those who were overweight/obese at 20 years were of normal weight at 5½ years and 47% at 15 years. The majority of those who were overweight/obese at 20 years of age were recruited after 5.5 years of age and half of them in their late teens. Another finding was that overweight and obese adolescents had more approximal caries than normal-weight adolescents. Furthermore, consumption of snacking products and soft drinks at an early age appears to be associated with caries at 15 years of age. There was no connection found between birth weight and later overweight/obesity at 20 years of age. The study could not demonstrate any distinct patterns of the weight development from early childhood to young adult. A child could, for example, have overweight/obesity at one measurement, have normal weight at the next and then again have overweight/obesity at the third measurement. Because dental caries and overweight/obesity have common determinants further prevention measures should include strategies to prevent and reduce both overweight/obesity and dental caries in the young population. During the preschool period, the entire population should be the target of primary prevention from overweight/obesity, while, in the case of teenagers, prevention strategies should be developed for the whole population and treatment strategies for teenagers with established overweight/obesity.

Pełny tekst źródłaThe aim of this thesis was to study adults and the elderly from South Brazil in regards to: (1) the prevalence, extent, and intra-oral distribution of coronal and root caries; (2) the relationship of educational status with coronal and root caries experience; (3) the prevalence estimates and risk indicators for coronal and root caries activity; and (4) the relationship of overweight and obesity with coronal and root caries experience. A cross-sectional population-based study was conducted between June 2011 and June 2012. A multistage sampling strategy was used to draw a representative sample of 1,023 individuals aged ≥35 years. Questionnaires recorded data on socio-demographic characteristics, oral hygiene habits, dental care, and smoking. Oral examination assessed gingival bleeding, gingival recession, and coronal and root caries. Anthropometric measures were collected to calculate the body mass index. Survey negative binomial models were used to assess the relationship of educational status, overweight and obesity with coronal and root caries experience. Survey Poisson regression models were used to assess the relationship of explanatory variables with coronal and root caries activity. The coronal and root caries prevalence was 99.73% (95% CI 99.31-100.00) and 41.14% (95% CI 37.57-44.72), respectively. The prevalence of coronal and root caries activity was 34.26% (95% CI 27.13-41.38) and 14.73% (95% CI 11.16-18.30), respectively. The mean coronal DMFT and root DFT scores was 18.73 (95% CI 18.29-19.17) and 1.15 (95% CI 0.95-1.34), respectively. The mean coronal DMFS and root DFS scores was 66.56 (95% CI 63.30-69.83) and 1.49 (95% CI 1.25-1.73), respectively. The mean coronal DMFS score was significantly higher in the older age groups compared to individuals aged 35-44 years. The mean coronal DS score significantly decreased between individuals aged 35-44 years and those aged 45-59 and ≥60 years. The mean coronal DS score significantly decreased between individuals aged 35-44 years and those aged 45-59 and ≥60 years. The mean coronal MS score significantly increased with age. The root caries estimates were significantly higher in individuals aged 45-59 and ≥60 years compared to those aged 35-44 years. Molars and premolars were the teeth most affected by coronal and root caries, respectively. The likelihood of coronal caries significantly decreased with a high educational status. The probability of root caries significantly increased with a high educational status. Overweight and obesity were not significantly associated with coronal and root caries experience. The likelihood of coronal caries activity significantly decreased with age ≥60 years, a higher tooth brushing frequency, a higher proximal tooth cleaning frequency, regular dental care, and a larger number of retained teeth, and significantly increased with ≥60% of bleeding sites. The likelihood of root caries activity significantly decreased with a larger number of retained teeth, and significantly increased with an intermediate-high educational status and a larger number of teeth with recession. Coronal caries activity significantly increased the probability of root caries activity by 394%. Thus, it was possible conclude that: (1) coronal and root caries were highly prevalent in this Brazilian population, and molars and premolars were the teeth most attacked by coronal and root caries, respectively; (2) educational status was a risk indicator for both coronal and root caries, but individuals with a high educational status should only be considered at high risk for root caries; (3) caries activity was highly prevalent in adults and the elderly, and those with coronal caries activity should be considered at high risk for root caries activity; and (4) overweight and obese individuals should not be considered at high risk for both coronal and root caries.

Pełny tekst źródłaThe work made during my PhD, respond to the problematic of physical simulation of the behavior of deformable objects subject to topological changes in interactive time. My work resulted in the definition of a new unified model coupling a complete topological model and a physical model for physical simulation of deformable objects decomposed in surface as volume elements, while performing during this simulation topological changes such as cutting or subdivision local of a mesh element. This operation allowed us to propose an adaptive method where mesh elements are refined during the simulation according to a geometric criterion. For the topological model of our unified model, we made the choice of combinatorial maps and more particularly linear cellular complexes. Their main advantage of the latter is the simplicity of its equations, its intuitive implementation, its interactivity and its ease to handle topological changes. Finally, the definition of a unified model allowed us to propose a model avoiding duplication of information and facilitate the update after topological changes

Pełny tekst źródłaAppeared in the mid-nineteenth century as a jargon in the artistic circles of Munich designating a cheap image of poor quality, the term “kitsch” is used today not only in the art world, but also in everyday life, always with strongly pejorative sense. Generally considered as “bad taste”, “worthless art”, “artistic junk” or “vulgar art”, kitsch, however, is not a concept that remains only in aesthetic or artistic field ?. Various historical phenomena of kitsch which had been all emerged in the context of modernity, such as “bib[e]lotomanie”, “serialized novel”, “academic art” in France in the nineteenth century, or “barbershop’s painting” in Korea in the twentieth century, show that kitsch is indeed an attitude of human being toward his own existence and the world. The essence of this concept lies therefore in his negation of reality, or better in his escape from reality. That’s why photography deserves to be studied in relation with the kitsch. Having a specific link with the reality, the medium oscillate ontologically between the present and the past, the instant and the eternity, the here and the elsewhere, the subject and the object, the life and the death, etc. It is indeed because of this paradoxical ontology that the photography can become, according to the “acte photographique” not just art but also kitsch. Thus, the attitude to the latter the artists let reveal through their photographic work turn out extremely varied and ambiguous, even contradictory such as it does in the work of Pierre et Gilles, Vik Muniz, Sebastião Salgado and Oliviero Toscani

Pełny tekst źródłaThe ideas of men and women having equal opportunities on labour market emerged only in the middle of the 20th century, therefore, female leadership is a new social and economical phenomenon. Although a sufficient legal base securing equal de jure opportunities for women and men in the labour market has been developed, in reality (de facto) career women still encounter many barriers (prevailing stereotypes, family and work combination issues, real insecurity of equal opportunities, etc.). In this case the mass media assumes the main role as a medium between leaders and society, influencing formation of a certain female leader image. The Master’s final paper analyzes and compares the real female leader image (based on the facts, research and statistics) and the one created by the mass media in Lithuania, including the conclusions of the aforesaid analysis. The main part of the paper consists of three main chapters. The first chapter includes the discussion on the statistic female leader portrait, opportunities of taking the leader position, prevailing social stereotypes, issues on unequal opportunities on labour market, family and work combination difficulties and the comparison of men and women in the role of the leader. The second chapter of the paper concentrates on the analysis and comparison of the female leader image provided by two different printed publications. The purpose of the third chapter is to describe the influence of the mass media upon the formation of... [to full text]

Pełny tekst źródłaTiivistelmä Tämän poikkileikkaustutkimuksen tavoitteena oli tutkia nepalilaisten koululaisten suunterveyttä ja siihen liittyvää elämänlaatua (OHRQoL). Toiseksi tavoitteena oli tutkia karieksen ja sen seurausten mm. oireet ja tulehdus, yhteyttä suunterveyteen liittyvään elämänlaatuun, sosiodemografisiin ja antropometrisiin tekijöihin, suunterveyskäyttäytymiseen, koulupoissaoloihin sekä -menestykseen. Tutkimus toteutettiin 18/75 satunnaisesti valitussa Nepalin piirikunnassa, jotka edustivat sekä viittä kehitysaluetta että kolmea ekologista aluetta. Mukaan kutsutuista 1157 koululaisesta (27 koulua, mukavuusotos), 1137 osallistui sekä kysely- että kliiniseen tutkimukseen. Sosiodemografiset taustatiedot sekä tiedot suunterveyskäyttäytymisestä kerättiin strukturoidulla kyselylomakkeella. Suunterveyteen liittyvää elämänlaatua arvioitiin käyttäen validoitua nepalin kielistä Child-OIDP –lomaketta. Kliinisessä tutkimuksessa tutkittiin kariestilanne, sen kliiniset seuraukset (pufa/PUFA) sekä kiinnityskudosten tila WHOn ohjeiden mukaan. BMI, vyötärön ja lantion ympärysmitan suhde sekä vyötärön ympärysmitan ja pituuden suhde laskettiin mittaustulosten perusteella. Kouluista saatiin tiedot poissaoloista viimeisen kouluvuoden aikana sekä koulumenestys kolmessa keskeisimmässä oppiaineessa viimeisimmässä todistuksessa. Lähes kaikilla todettiin ienverenvuotoa. Nuorimmassa ikäryhmässä oli muita useammin korjaavan karieshoidon tarvetta (79% vs. 64%). Kariesta sekä sen seurauksia esiintyi eniten niiden keskuudessa, jotka asuivat Kathmandun laaksossa tai vuoristossa. Karieksen esiintyvyys oli myös yhteydessä mm. sokerin, makeisten ja sokeriteen kulutukseen sekä epäsäännölliseen hampaiden harjaukseen. Karies seurauksineen oli yhteydessä huonoon suunterveyteen liittyvään elämänlaatuun (OHRQoL), erityisesti syömiseen, suun puhdistamiseen sekä nukkumiseen. Sillä oli myös yhteys sekä matalaan että korkeaan BMIhin, lisääntyneisiin koulupoissaoloihin sekä huonoon koulumenestykseen. Matala ja korkea BMI, huono suunterveyteen liittyvä elämänlaatu sekä poissaolot olivat käänteisesti yhteydessä koulumenestykseen. Karies ja ienverenvuoto ovat yleisiä nepalilaisten koululaisten keskuudessa. Karies seurauksineen on yhteydessä huonoon suunterveyteen liittyvään elämänlaatuun (OHRQoL), haitalliseen suunterveyskäyttäytymiseen, sosiodemografisiin ja antropometrisiin tekijöihin (BMI, keskivartalolihavuus) sekä lisääntyneisiin koulupoissaoloihin ja huonoon koulumenestykseen

Pełny tekst źródłaThis thesis is the interaction result of two disciplines that are the change detection in multitemporal images and the evidential reasoning using the Dempster-Shafer theory (DST). Addressing the problem of change detection and analyzing by the DST, requires the determination of an exhaustive and exclusive frame of discernment. This issue is complex when images lake prior information. In this research work, we propose a new clustering algorithm based on the Fuzzy-C-Means (FCM) algorithm in order to define existing semantic classes. The idea of this algorithm is the representation of each class by a varied number of centroids in order to guarantee a better characterization of classes. To ensure the frame of discernment exhaustiveness, we proposed a new cluster validity index able to identify the optimal number of semantic classes. The third contribution is to exploit the position of the pixel in relation to class centroids and its membership distribution in order to define the mass distribution that represents information. The particularity of the proposed distribution, is the generation of a reduced set of focal elements and the respect of mathematical axioms when performing the fuzzy-mass transformation. We have emphasized the capacity of evidential conflict to indicate multi-temporal transformations. We reasoned on the decomposition of the global conflict and the estimation of the partial conflicts between the couples of focal elements to measure the conflict caused by the change. This strategy allows to identify the couple of classes that participate in the change. To quantify this conflict, we proposed a new measure of change noted CM. Finally, we proposed an algorithm to deduce the binary map of changes from the partial conflicts map

Pełny tekst źródłaGeological hazards represent a research topic that is in constant development. Populated areas are ever expanding and the requirements for the control of the hazards they represent are becoming increasingly significant. Orogenic zones are among the areas affected by different types of hazards. This study focuses on the evaluation of mass movement (MM) hazard which is the most common hazard in the Northwest part of the Rifain belt in Morocco. It introduces a three-step procedure to assess mas movement hazard (MMH). Nine contextual variables that characterize the geological environment (lithology, fracturing, seismicity, slope gradient, elevation, aspect, stream’s net, precipitation and land-use) were mapped and classified in order to better understand their interrelationships and their respective effects in the onest of MM. Following this, the classification, inventory, description and the analysis of the MM were carried out by interpretation of high remote sensing data associated to the field study. Finally, MMS was assessed using a multi-scale approach (small = 1/100,000 ; mean = 1/50,000). At the small scale, this assessment was carried out using an index-based approach where the rating nd weighting of each parameter was introduced based on real statistical data to reduce the subjectivity of the method. At the meso-scale, this evaluation was performed by applying and comparing two probabilistic approaches. These are: (i) the bivariate weights of evidence approach (WOEA), and (ii) the multivariate logistic regression approach (LRA). WOEA proved most successful in predicting landslides hazard and LR proved most successfull in modeling rockfalls and debris flow at the meso-scale in a North African mountain environment. The various maps produced constitute a powerful decision-making tool to present, compare and discuss scenarios of town and land-use planning, i. E. Urban planning, works or road plans. These results are part of a sustainable development framework winch allows mitigating the socioeconomic impacts that are usually noticed during the release of MM

У дисертації вирішена актуальна наукова задача, що полягає у встановлені закономірностей розповсюдження пилової хмари після масових вибухів в залізорудних кар’єрах та рівнем її екологічної небезпеки і розробці на цій основі екологічно ефективних способів та засобів зменшення викидів пилу у довкілля. Розроблені методичні засади визначення висоти підйому пилових частинок залізорудного пилу під дією теплових чинників як при наявності вітру, так і при його відсутності. Розроблено спосіб та засіб зменшення висоти підйому пилової хмари дальності її розповсюдження, які передбачають проведення робіт з оптимізації параметрів свердловинних зарядів, а також використання в якості набійки свердловинних зарядів гумової пробки з анкерним пристроєм. Удосконалено спосіб захисту довкілля від викидів пилу шляхом зрошування пилової хмари в цілому, обґрунтовано необхідний діаметр капель води для забезпечення максимальної ефективності пилопригнічення, а також об’єм води для цого. Для транспортуваня та розбризкування води над пиловою хмарою обґрунтовано використання спеціальним чином обладнаних вертольотів. Ступінь екологічної небезпеки при впровадженні запропонованих способів та засобів знепилення досягає рівня “безпечний”.
В диссертации решена актуальная научная задача, которая заключається в установлении закономерностей рассеивания пылевого облака после массовых взрывов в железорудных карьерах и уровня изменения его экологической опасности, а также разработке на их основе экологически эффективных способов и средств снижения выбросов пыли в окружающую среду. На основании результатов анализа рассеивания пылевого облака, образовавшегося после массового взрыва, выполнена оценка опасности загрязнения прилегающих территорий по пылевому фактору. Показано, что уровень экологической опасности от загрязнения воздуха пылью в радиусе 10 км представляется как “очень опасный”, а степень загрязнения – “недопустимая”. Уровень загрязнения пылью атмосферного воздуха и прилегающих территорий зависит от высоты подъёма пылевого облака, объёмов выброса пыли, метеорологических условий и эффективности способов и средств пылеподавления. В результате анализа существующих способов и средств подавления пылевого облака сделан вывод о необходимости их совершенствования. Для оценки экологической опасности рассеивания пылевого облака разработана методика расчёта высоты его подъёма с учётом дисперсности пылевых частиц и других влияющих факторов, что позволило выполнить расчёты рассеивания пыли в атмосфере для оценки эффективности технических мероприятий, направленных на снижение или локализацию выбросов пыли и её рассеивания. Расчёты рассеивания пылевого облака при мощности взрыва 500 т “украинита”, скорости ветра 5 м/с и нормальных метеорологических условиях показали, что дальность выноса грубодисперсной железорудной пыли составляет от 0,14 до 4,4 км, а тонкодисперсной – от 40 до, примерно, 740 км. При этом удельные выбросы пыли при общей площади рассеивания до 28770 км2 достигают 1,302 кг/км2. Разработан способ снижения высоты выброса пылегазового облака при массовом взрыве на основе оптимизации параметров скважинных зарядов (удельного заряда ВВ, диаметра скважин и соотношения длины забойки и взрывчатки в скважине). Предложена также усовершенствованная конструкция забойки скважинных зарядов, которая предусматривает использование в составе забойки резиновой пробки с анкерным устройством. Расчёты показали, что при применении этих разработок высота выброса пылегазового облака при массовом взрыве может быть снижена на величину до 30%. В работе выполнены исследования параметров подавления пылевого облака путём его орошения. Получено аналитическое выражение для оценки эффективности пылеулавливания от диаметра пылевых частиц и капель воды, скорости их движения, количества орошаемой жидкости, высоты орошения облака, а также суммарного коэффициента захвата пылевых частиц каплями жидкости. Установлено, что суммарный коэффициент захвата для тонкодисперсной пыли имеет максимальное значение 0,488 при диаметре капель воды 1 – 1,5 мм. Для грубодисперсной пыли при этих диаметрах капель воды коэффициент захвата изменяется от 0,815 до 0,996. При этом удельный расход воды для подавления тонкодисперсной фракции пыли составляет 3,195 л/кг. В качестве технического средства транспортирования орошающей жидкости и разбрызгивания её над пылевым облаком предложено использование специально оборудованных вертолётов. Оценка снижения экологической нагрузки на прилегающие территории при этом показала, что общий выброс пыли из карьера при массовом взрыве может быть снижен на 90 %. Степень экологической опасности при внедрении предложенных способов и средств пылеподавления достигает уровня “безопасный”.

Methods: Bibliographic research of scientific articles in the electronic database PubMed, Web of Science and B-On. Combined search terms were used: dental caries, BMI, children, pediatric patient, obesity and saliva. The selection of articles was made by applying inclusion and exclusion criteria. Sixty four articles were selected for the development of this narrative review. Topic covered: Since there is no direct and incontestable relationship between dental caries and obesity in children, the dentists who treat these patients must act as public health agents, alerting children and their guardians about risks and implications that overweight and obesity in children pose to children's oral and general health.

A systematic revision was done, including several articles of scientific investigation developed in several countries from all the continents, searching to specify that relationship in children aged 2 to 18, in public and private schools, coming from families showing different social, economic and regional origin. A weaker global oral health is observed in children presenting lower body mass index and obesity and also in those belonging to less favoured social and economic environments, with habits of bigger sugar ingestion and poorer nourishment regarding to healthy nutrients. This causes pathologies such as dental caries. There is a major focus on the need of promoting a wider education for oral health in schools and near families, by means of teachers and health authorities, stressing the family´s doctor role.

Pełny tekst źródłaIntroduction: Overweight and obesity are defined as abnormal or excessive fat accumulation. That pathology leads to different problems in various body systems and in oral cavity, too. Dental caries and periodontal disease have been related with overweight but the scientific community is not yet unanimous regarding the subject. The aim of this study was to evaluate how overweight and obesity have impact on lifestyle, oral habits and oral pathologies, having in concern social state, systemic pathologies and nutritional lifestyle. Methods: We conducted an observational, cross-sectional study where we applied a questionnaire to 140 individuals, those 70 had a normal BMI and 70 had an excessive BMI, in Lisbon and Viseu. We also realized an oral inspection in each individual to record the indexes DMFT, CPI and the hygiene oral state. Results: From the final sample, 30% of the subjects with overweight brush their teeth once a day or less, while the majority (62,9%) of the control group brush twice daily. In oral examination, 70% had calculus, while control group only had 22,5% of the population with calcified plaque. Also DMFT increased since group control to obesity group. Regarding periodontal disease, people with overweight are the ones that need more medical intervention (81,4%) in contrast with group control (14%). Conclusions: Most overweight individuals present precarious oral hygiene habits, higher incidences of dental caries, and worse periods of periodontal health. They are not sensitized to the repercussions of association of their cariogenic diet, oral health and overweight.

Pełny tekst źródłaIntroduction and objectives: The oral health in athletes is essential part of general health, being a determining factor in the quality of life and sports performance. Soon a good health only exist if the oral cavity is absent pathologies. The nutritional imbalances have effects on the oral cavity, thus conditioning the quality of life and athletic performance. Thus, excessive intake of certain foods can be risk factors for health, with regard to the etiology of dental caries is associated with the action of oral micro-organisms produce organic acids from the metabolism of carbohydrates. The aim of this study was to evaluate the oral health and eating habits and the use of mouthguards during sports. Participants and Methods: There were 55 volleyball athletes between 15 and 18 years of both sexes, Volleyball Club Academy José Moreira and Leixões. This was a cross- sectional study, which was conducted intraoral clinical examination (caries DMFT index, dental erosion index BEWE) and fill questionnaire, in which individuals were characterized in five components: socio-demographic data (age, weight and height), data on health perception, behaviour data on oral health data on sport and data on eating behaviours (semi-quantitative food frequency questionnaire). Descriptive and inferential statistical analysis of the data collected was performed with the SPSS software package, version 23.0. Results: Oral helth habits are not the most appropriate and the percentage of athletes who visit the dentist is high to “only when have hain” or “occasionally”. The overall average DMFT was 4.22 ± 4.55. There were no statistically significant differences (p> 0.05) between the general DMFT and BMI. None of the athletes use mouthguards during sports. The most consumed foods were meat, fruit, milk, fish and biscuits, cakes and biscuits; and the least consumed were alcohol, honey or jam and coffee. Conclusion: Oral hygiene habits are a better indicators than BMI for the presence of caries. There is no direct relationship between DMFT and BMI index. It would be important to provide more information about the use of mouthguards advantages among athletes and coaches as well as to clarify that the consistency and sensory properties linked to the texture and consistency of the food on the tooth surface interfere with caries.

Pełny tekst źródłaThe research aims to determine the distribution patterns of crustacean plankton along the longitudinal (west-east) and transversal (north shore - south shore) axes of the St. Lawrence River between Lake Saint-François and the estuarine transition zone, during two hydroperiods in May (high discharge) and August (low discharge). The zooplankton samples and the environmental data were collected at 52 stations distributed along 16 transversal transects in 2006. In chapter 1, we present the theoretical concepts of river ecosystem models, and a synthesis on the generative processes driving zooplankton spatial patterns in rivers. We also present our research objectives and hypotheses. In chapter 2, we describe spatial patterns of the zooplankton community structure in three biogeographic zones of the St. Lawrence and 6 longitudinal habitats, together with the relationships between zooplankton spatial structure and water masses spatial distribution and environmental characteristics. In chapter 3, we perform a variation partitioning procedure on spatial variables AEM (based on water masses spatial distribution) and environmental variables in order to assess how much of the zooplankton variation is explained by hydrological processes (AEM variables) and local conditions (environmental factors). The salinity-conductivity gradient related to the fluvial-estuary discontinuity determines the large-scale spatial patterns of the crustacean zooplankton. In the fluvial zones, the zooplankton distribution patterns are more influenced by the water masses spatial structure than by local environmental factors. The spatial distribution of the water masses explained more of the spatial structure of zooplankton communities in August than in May.
