Ozonation has been utilized for water treatment for over 100 years. During that time, the range of applications has grown considerably, and includes the remediation of nursery and greenhouse irrigation water. Ozone is dissolved into irrigation water to kill pathogens and degrade chemical contaminants. By convention, growers remove ozone from solutions, prior to distribution to the crop, to avoid phytotoxic effects. The available literature regarding aqueous ozone (O3(aq)) phytotoxicity is limited, making this a sagacious practice, although the removal does preclude any ancillary benefits beyond the point of treatment. The effects of applying O3(aq) under two irrigation systems are examined. Initial studies suggested O3(aq) concentrations as high as 20 mg⋅L-1 could be applied directly to mineral wool substrate in a limited (one time) fashion without a negative response. To be effective as a remediation tool, however, ozone would need to be applied more frequently (e.g. daily). The effects of daily O3(aq) application, via drip irrigation in mineral wool hydroponic tomato culture, was examined. In the first of two studies, daily applications of 3.0 mg⋅L-1 O3(aq) elicited an overall positive growth response. In a follow-up study, 6.0 mg L-1 elicited a negative response. Nursery operators often utilize overhead irrigation. A study was conducted to determine if overhead irrigation utilizing O3(aq) was compatible with select woody perennial nursery species. The amount of ozone lost from solution during application was examined, as well as crop response to the ozone environment generated. It was shown that 60 to 70% of the ozone was unaccounted for at canopy level, while phytotoxic effects were elicited at emitter concentrations above 1.5 mg L-1. Marchantia polymorpha is a significant weed species in greenhouse and nursery production; a species with few control options. Anatomical features of M. polymorpha suggested sensitivity to O3(aq). Studies were performed to examine contact time (CT) and exposure frequencies required for M. polymorpha suppression. A CT of 0.84 mg⋅L-1⋅min at an application frequency of 3-times/week achieved measurable suppression. / Natural Science and Engineering Research Council (NSEARC); Ontario Ministry of Agriculture Food and Rural Affairs (OMAFRA); Ontario Centres of Excellence (OCE); Purification Research Technologies INC (PRTI); Flowers Canada (Ontario).

Experiments were conducted to assess effects of nursery feeding programs (using complex or simple diets, including or excluding antibiotics) on growth performance of barrows and gilts up to market weight (approximately 115 kg body weight), plasma levels of growth-related hormones, chemical body composition and carcass traits at market weight. Reducing nursery diet complexity decreased (P < 0.05) growth performance and plasma levels of triiodothyronine during the nursery period, but had no negative carry-over effects on growth performance or hormone plasma levels thereafter. Excluding antibiotics from nursery diets reduced nursery growth performance and plasma levels of insulin-like growth factor-1 and triiodothyronine but appeared to induce subsequent compensatory growth. In general, nursery feeding programs had no effect on body composition and carcass traits at market weight and no effect on wean-to-finish growth performance or carcass value at market weight. This represents an opportunity to improve profitability in commercial pork production. / Ontario Pork; The Ontario Ministry of Agriculture, Food and Rural Affairs; Canadian Agriculture and Agri-Food Swine Research Cluster

The sample was composed by 253 patients underwent abdominal surgeries. The results showed a total of 63.63% females between 38 and 47 years of age (21.34%); illiterates (21.73%); married (64.03%), living in Natal and surroundings (67.97%) and Catholics (74.30%). In their first assessment, 84.19% showed postoperative pain; the pain was considered light in 18.97% of them, moderate in 21.74% and severe in 43.48%. The mean number of descriptors chosen through the McGill Questionnaire Pain was 10.78 (DP= 6.09) and pain rating 23.65 (DP= 15.93). The descriptors selected with higher frequency were: sickening pain (69.01%), tired (65.25%), thin (62.44%), bored (58.69%), ardor (46.48%), pointed (38.50%) and colic (35.21%). In their second assessment, 57.71% of patients didn t relate any postoperative pain and 42.29% were still complaining about the pain. After taking analgesic medication, just 41.90% of patients who had complete pain relief. The Pharmacological groups most used were: simple analgesic (37.86%), weak opioids (32.98%), AINES (19.85%) and strong opioid (9.31%). It was not found a significant postoperative pain variation related to the sexes, religion and kind of surgery. It was concluded there were a high level in the number of patients with postoperative pain, mainly in a severe scale. Less than half of patients had the pain relief. Then, it was observed there was not coherence between the pain intensity and the analgesic it was used. To solve or relieve this kind of problems is necessary a permanent education to the health professionals who works in this area / Estudo explorat?rio descritivo, com abordagem quantitativa, desenvolvido entre fevereiro e maio de 2010, com o objetivo de avaliar a dor dos pacientes submetidos a cirurgias abdominais em um Hospital Universit?rio, em Natal/RN; identificar a localiza??o e a intensidade dolorosa mensurada pela Escala de Estimativa Num?rica; analisar a dor nas dimens?es sensorial-discriminativa, motivacional-afetiva e a cognitivo-avaliativa, utilizando o Question?rio para dor McGill; relacionar o processo ?lgico com a idade, sexo, religi?o e tipo de abordagem cir?rgica; identificar a efetividade da medica??o utilizada no al?vio da dor p?s-operat?ria. A amostra constou de 253 pacientes submetidos a cirurgias abdominais. Os resultados mostraram que 63,63% eram mulheres, entre 38 e 47 anos (21,34%); n?o alfabetizados (21,73%), casadas (64,03%), procedentes da grande Natal (67,97%) e cat?licas (74,30%). Na primeira avalia??o, 84,19% apresentaram dor p?s-operat?ria; 18,97% apresentaram dor leve; 21,74% moderada e 43,48% severa. A m?dia do n?mero de descritores escolhidos atrav?s do Question?rio de Dor McGill foi 10,78 (DP= 6,09) e o ?ndice de dor 23,65 (DP= 15,93). Os descritores escolhidos com maior frequ?ncia foram: dor enjoada (69,01%), cansativa (65,25%), fina (62,44%), aborrecida (58,69%), ardor (46,48%), pontada (38,50%) e c?lica (35,21%). Na segunda avalia??o, 57,71% pacientes n?o referiram dor p?s-operat?ria e 42,29% continuaram com queixas de dor. Apenas 41,90% dos pacientes tiveram sua dor totalmente aliviada ap?s administra??o do analg?sico. Os grupos farmacol?gicos mais utilizados foram os analg?sicos simples 37,86%, opi?ides fracos 32,98%, AINES 19,85% e opi?ides fortes 9,31%. N?o encontramos rela??o significativa entre a vari?vel dor p?s-operat?ria com o sexo, religi?o e tipo de abordagem cir?rgica. Conclu?mos que houve uma alta preval?ncia de dor p?s-operat?ria, principalmente a de intensidade severa. A dor foi efetivamente aliviada em menos da metade dos pacientes. Dessa forma, percebemos que n?o existia coer?ncia entre a intensidade da dor do paciente e o analg?sico administrado para o seu al?vio. A educa??o permanente dos profissionais de sa?de dever? ser uma das a??es mais eficazes para evitar ou minimizar a ocorr?ncia desse evento

Since 1970, the number of Cesarean sections has constantly increased in the country and worldwide. In 2014, in Brazil, it reached 52% of the deliveries, even though surgical births levels above 15% do not indicate protection for mother and baby, according to the WHO. The literature indicates that children born by Elective C-section without labor are at higher risk of biological development problems, but few studies address the consequences in the psychological aspects. The objective of this study was to compare the psychological development among babies born of elective C-section and normal delivery, considering the few data available in the literature. Considering the exclusion criteria, the sample consisted of 263 children aged between 6 and 42 months. The instruments used were: a sociodemographic questionnaire to be answered by the mother, and the Bayley Scales of Infant Development – 3rd Edition. For this study the scale was standardized and the sample data collected normalized using percentile calculation. These data were collected individually and statistically analyzed through the SPSS - Statistical Package for Social Sciences Version 21. The results pointed out the delivery method and the gestational age at birth as risk factors for child’s psychological development. The correlations among those born by vaginal delivery or elective C-section showed a statistically significant difference (p <0.05). Among the latter, 12% presented inferior performance in relation to sensory processing, and 10 to 19% in adaptive behavior skills. The correlations with gestational age at birth, also revealed a statistically significant difference (p <0.05): 12% of the preterm infants presented lower results in the development of expressive language and 9% in fine motor skills. These results indicate that, in addition to the losses in physical development, widely described in the national and international literature, there is evidence of psychological impairment. Signs of compatibility and divergence between the US and local samples were observed. / A realidade obstétrica no país vem sofrendo alterações significativas nos últimos dois anos. Desde 1970 tem sido crescente o número de cesarianas no país e no mundo. Em 2014, o número de partos cirúrgicos no Brasil chegou a 52%, apesar de índices superiores a 15% de partos cirúrgicos não indicarem proteção à mãe e ao bebê, segundo a Organização Mundial de Saúde. A literatura aponta que crianças nascidas por cesárea eletiva sem trabalho de parto enfrentam maior risco de problemas em seu desenvolvimento orgânico, mas poucos estudos abordam as consequências nos aspectos psicológicos. O objetivo deste estudo foi comparar o desenvolvimento psicológico entre bebês nascidos de cesárea eletiva e de parto normal, uma vez que há poucos dados disponíveis na literatura. Considerando os critérios de exclusão, foi utilizada amostra composta por 263 crianças com idades entre 6 e 42 meses. Os instrumentos utilizados foram: questionário sociodemográfico respondido pela mãe da criança e a Bayley Scales of Infant Development – 3rd Edition. Foi realizada a padronização da escala e a normatização dos dados amostrais através do cálculo de percentil, para uso neste estudo. Estes dados foram coletados individualmente e analisados estatisticamente através do SPSS - Statistical Package for the Social Sciences Version 21. Os resultados apontaram a via de parto e a idade gestacional ao nascer como fatores de risco ao desenvolvimento psicológico da criança. Nas correlações realizadas entre os nascidos por parto vaginal ou cesárea eletiva, foi verificada diferença estatisticamente significativa (p<0,05). Dentre estes últimos, 12% apresentaram desempenho inferior em relação ao processamento sensorial, e 10 a 19% nas habilidades do comportamento adaptativo. Nas correlações com a idade gestacional ao nascer, também se observou diferença estatisticamente significativa (p<0,05): 12% dos nascidos a termo precoce apresentaram resultados inferiores no desenvolvimento da linguagem expressiva e 9% na motricidade fina. Estes resultados indicam que, além dos prejuízos no desenvolvimento físico, amplamente descrito pela literatura nacional e internacional, há indícios de comprometimento psicológico. Observaram-se indícios de compatibilidade e divergências entre as amostras norte-americana e local.

The second chapter is about the usage of new vegetal indices NI, PI, KI, CaI, MgI, SI, MnI, FeI, ZnI, CuI and BI in the estimate of macro and micronutrients level in eucalyptus under nursery tree conditions by using spectral reflectance. During the research, data from spectral reflectance was collected from isolated leaves, in the genetical material AEC 2034 ((Eucalyptus camaldulensis Dehnh x Eucalyptus grandis Hill (ex Maiden)) x Eucalyptus urophylla S.T. Blake) and AEC 2475 (Eucalyptus urophylla S.T. Blake x Eucalyptus pellita F. Muell) in clonal mini-garden and seedlings production of 65 days old. Spectral data was collected using a portable foliar spectrometer CI-710 (CID, Inc., Camas, Washington, USA). The spectral curves in the clonal mini-garden were statistically equal from 400 to 900 length, and statistically different in the violet, blue and ifrared surrounding area. In the seedlings production the spectral curves were statistically different from 400 to 900 nm and in all evaluated area. The vegatation indices presented good estimates under the conditions of clonal mini-garden and seedlings production, considering that the estimates were possible due to the vegetation indices in the clonal mini-garden and seedling production. The vegetation indices that showed the best estimate of nutrients content under clonal mini-garden conditions and seedlings production were the ones situated in the red edge area.

The thesis, on the subject of "The ideal nursery-school teacher in the eyes of parents", surveys the perspective of parents of children attending nursery school and investigates their point of view as to what the perfect nursery-school teacher should be like, while taking into consideration the gender of the respondents. The author focuses primarily on the theoretical specification of the nursery-school teacher's personality and professional competence, differentiation of teacher typology, education styles, the concept of authority and the related work agenda and demands connected with practising this profession. She also outlines the scientific discipline of pedeutology and existing research. In the practical section, a quantitative research investigation is made by way of questionnaire. The questionnaire is anonymous so as to protect the anonymity of the respondents. The research sample comprises the parents of children attending nursery school in the town of Písek. The responses reflect the respondents' opinions with respect to their idea of the perfect nursery-school teacher, and will be compared with hypotheses and then analysed. The thesis aims to ascertain the respondents' majority view as to the nursery-teacher ideal, the characteristics they most often want/prefer, the type of teacher (according to the typology in the theoretical section of the thesis) to which these characteristics best correspond, and whether or how ideas about the perfect nursery-school teacher vary.

Cette thèse porte sur les contenus d’enseignement et d’apprentissage de l’école maternelle. Présentée par Reuter (dir. 2007 : 45) comme renvoyant « à des choses aussi diverses que les savoirs, les savoir-faire ou les compétences qui sont les objets d’enseignement et/ou d’apprentissage les plus immédiatement identifiables dans un système didactique, mais aussi des valeurs, des pratiques, des “rapports àˮ, voire des comportements ou des attitudes. », la notion de contenus a été approchée à partir de trois corpus issus de différents espaces : l’espace de prescription (textes officiels), l’espace de recommandation (ouvrages généraux sur l’école maternelle et livres axés sur un champ disciplinaire particulier) et celui de pratiques (transcriptions de séances de classes). Les analyses menées à l’aide d’outils relevant de la linguistique (analyse de discours) et de différentes didactiques disciplinaires ont permis de mettre en relief, entre autres, une différence au sein de l’organisation structurelle des contenus présentés par les instructions officielles (organisation par thèmes et selon les domaines d’activités). De plus j’ai noté la pérennité de contenus tels que les savoirs et savoir-faire au cours de l’histoire de l’institution ainsi que l’apparition dans les années 1990 de nouveaux contenus , à savoir les compétences, la prise de conscience et “rapport àˮ). Par ailleurs, il existerait un lien entre ces différentes catégories et l’inscription disciplinaire des contenus. / This thesis focuses on teatching and learning contents in nursery school. For Reuter it refers « to such diverse things as knowledge and know-how or skills (both are teaching and/or learning contents immediately identifiable in a training system), values and practices, the « relationships to/with », and even behaviours and attitudes »To study the notion of content we based our research on a corpus of documents from three different sources : official texts, books on nursery school and specific academic fields, and transcripts of actual classroom sessions.Analyses carried out using tools from linguistic and academic training fields have highlighted a different structural organisation of contents in official texts (organisation by topics and by fields of activity). The analyses also revealed the continuity of knowledge and know-how contents throughout the history of nursery school, as well as the emergence of new contents (skills, awareness and relationships to/with ) in the 90'. Furthermore, there is a link between these categories and the location of contents in academic fields.

La perte d'habitat engendrée par l'artificialisation des côtes a de graves conséquences sur la biodiversité marine. Aussi, dans une optique de maintien de la biodiversité et des stocks de poissons, il peut s’avérer intéressant de restaurer certaines fonctions écologiques dans les zones anthropisées. Cette thèse avait pour objectif d’estimer le rôle potentiel des ports en tant qu’habitat pour les juvéniles de poissons côtiers et d’évaluer dans quelle mesure ce rôle peut être amélioré par le biais d’actions de restauration. Des expérimentations en aquarium ont permis d’estimer que le taux de survie des juvéniles sur des habitats artificiels utilisés à des fins de restauration était comparable à celui observé sur des roches. Une étude de la distribution spatiale des juvéniles à l’échelle d’un paysage sous-marin a ensuite montré que les ports pouvaient abriter des densités en juvéniles représentant de 50 à 90 % de celles retrouvées en milieu naturel. Les densités à l'intérieur des ports étaient cependant tributaires du type d’habitat considéré; les quais sans complexité structurale abritant les densités les plus faibles. Enfin, l'étude de cas concrets, a montré que la réhabilitation des ports pouvait significativement augmenter les densités de juvéniles à l’échelle de l’habitat, celles-ci pouvant atteindre des niveaux comparables au milieu naturel. Toutefois, ces bénéfices restaient faibles à l’échelle d’un port dans sa globalité. Ces travaux suggèrent un réel potentiel des infrastructures portuaires en tant qu’habitat juvénile alternatif, en particulier si des actions de restauration y sont entreprises. Cependant, pour plus d’efficacité, les projets de restauration devraient être menés à large échelle et utiliser une diversité d’habitats artificiels. La restauration écologique des ports peut ainsi être employée comme un outil complémentaire aux mesures de protection dans le cadre d’une gestion intégrée des zones côtières à l’échelle du paysage. / Habitat loss caused by urban sprawl has harmful consequences on marine biodiversity. With a view to maintaining biodiversity and fish stocks, it may be worthwhile to restore some ecological features in anthropized areas. The aim of this thesis was to estimate the potential role of ports as habitat for juvenile coastal fish and to evaluate how this role can be improvedthrough restoration actions. Tank experiments revealed that juvenile survival rate on artificial habitats used for restoration purpose could be equivalent to that observed on natural habitat. The assessment of the spatial distribution of juvenile at the scale of a seascape permitted to estimate that harbors could host densities of juvenile that were between 50 to 90% of thoseobserved in natural sites. Within harbors densities were highly dependent on the type of habitat, featureless dock hosting the lowest densities. Subsequently, based on case studies, this work demonstrated that harbors rehabilitation could significantly enhance juvenile densities at the habitat scale. Densities on restored habitat might reach those observed in natural habitats.However, at the scale of the whole harbor benefits were low. This work suggests that harbors have a real potential as an alternative juvenile habitat, especially if restoration actions are undergone. However, for more efficiency, restoration projects should be led at the scale of the whole site and include a diversity of artificial habitats. Thereby, restoration approaches shouldbe considered as a complementary tool to protection measures in a seascape integrated management approach of coastal areas

It analyses the relations established among the educators which work with infantile education, under the scope of the genre relations. At first, it discusses the historical path of the infantile Education in the main Laws and Documents that guide the Brazilian Education under the gender scope. Next, in a reflexive course, the analysis is inspired into the studies of the gender category, and brings important reflections about its definition, as well as its historical, political and social context, according to the authors: Joan Scott, Guacira Lopes Louro, Fúlvia Rosemberg and Jane Soares de Almeida. The focus of the research is guided based on the relations which are established among the educators of the institutions of infantile education. And the repercussion of these relations in the infantile education. There are many conflicts and barriers in infantile education under the scope of genders. However throughout the years several goals were reached in the perspective of the relations of gender in this teaching approach. Analyzing the relations among educators of a day nursery, it was noticed that the relations established in the infantile education present themselves as one of the ways of introduction of boys and girls in a social life. And, to think about the interaction among peers, being them little or big, boys and girls and it is as giving an opportunity to the most diverse understandings about oneself, about the other and the reality.(AU) / A presente pesquisa apresenta-se em uma perspectiva qualitativa, de cunho etnográfico. Analisa as relações estabelecidas entre os educadores e educadoras que trabalham com a educação infantil, sob a ótica das relações de gênero. Inicialmente, discute o percurso histórico da Educação Infantil nas principais Leis e Documentos que orientam a Educação Brasileira sob a ótica de gênero. Em seguida, em uma trajetória reflexiva, a análise passa a ser inspirada nos estudos da categoria gênero, e traz reflexões importantes acerca da sua definição, bem como do seu contexto histórico, político e social, segundo as autoras Joan Scott, Guacira Lopes Louro, Fúlvia Rosemberg e Jane Soares de Almeida. O foco da pesquisa está direcionado nas relações que se estabelecem entre os educadores e educadoras das instituições de educação infantil. E a repercussão dessas relações na educação das crianças pequenas. Muitos são os conflitos e barreiras da educação infantil sob a ótica de gênero. Porém, ao longo dos anos várias conquistas foram alcançadas na perspectiva das relações de gênero nessa modalidade de ensino. Ao se analisar as relações entre educadoras e educadores de uma creche, verificou-se que as relações estabelecidas na educação infantil apresentam-se como uma das formas de introdução de meninos e meninas na vida social. E, pensar na interação entre os pares, sejam eles grandes ou pequenos, meninos e meninas é oportunizar as mais variadas compreensões de si, do outro e da realidade.(AU)
