Micropropagação e acompanhamento bioquímico, fisiológico e nutricional da babosa (Aloe vera (L.) Burm. f.) cultivada ex vitro em doses de nitrogênio / Micropropagation and biochemical, physiological and nutritional aspects of Aloe vera (L.) burm.f cultivated ex vitro under nitrogen ratesEnio Tiago de Oliveira 14 December 2007 (has links)
A babosa (Aloe vera (L.) Burm. f.), família Asphodelaceae, reconhecida e explorada mundialmente pela indústria farmacêutica e cosmética devido aos princípios medicinais de seus compostos fenólicos e principalmente ao gel de polissacarídeos específicos, foi submetida a dois experimentos interligados. O primeiro, refere-se a micropropagação no qual foram avaliados tratamentos de desinfestação de ápices caulinares, multiplicação in vitro e condições de aclimatação ex vitro. O segundo experimento refere-se ao cultivo das plantas em areia lavada e irrigada com solução nutritiva, em condições controladas de casa de vegetação, onde foram testados os efeitos de doses (105; 210 e 315 ppm) de nitrogênio avaliados aos 90; 180 e 270 dias de cultivo. Os efeitos foram avaliados em função dos teores foliares dos macronutrientes e dos micronutrientes boro, cobre, ferro manganês e zinco, de proteínas totais solúveis (PTS), de açúcares redutores (AR) e açúcares totais solúveis (ATS) e sobre o crescimento por meio do índice de área foliar (IAF), da taxa de assimilação líquida (TAL), taxa de crescimento relativo (TCR), taxa de crescimento absoluto (TCA) e incrementos de massas de matérias fresca (IMMF) e seca (IMMS). Todos os dados foram analisados estatisticamente. Em relação a micropropagação, a eficiência de desinfestação foi aumentada em torno de 40% na obtenção de ápices caulinares verdes em início de brotação quando as plantas colhidas a campo foram previamente desinfestadas por lavagem com solução de hipoclorito de sódio com 0,5% de cloro ativo ou com solução de dicloroisocianurato de sódio (Sumaveg®) 0,66%. p.v-1 e os ápices caulinares submetidos a imersões alternadas nas soluções dos dois produtos utilizados. A fase multiplicativa da microproagação em meio MS apresentou um rendimento de 1:5,3 a cada intervalo de 30 dias de multiplicação. A partir de 136 ápices caulinares desinfestados, verdes, em início de brotação, foram obtidas 40.495 microplantas. Classificadas em pequenas, médias e grandes, foram submetidas a condições de aclimatação observando-se que bandejas de 64 células com 40 cm3 de substrato apresentaram economia em torno de 50% de substrato e em espaço físico na casa-de-vegetação com micro-aspersão e exaustão de ar em sistema \"pad-house\", e durante o processo de aclimatação e transporte das microplantas aclimatadas. Em relação ao cultivo das plantas em doses de nitrogênio, apesar de algumas variáveis responderem melhor à dose de 105 ppm e outras à dose de 315 ppm, a dose de 210 ppm de nitrogênio favoreceu as melhores respostas para os teores de açúcares totais solúveis (504,21 mgATS.g-1 de MMS), que são diretamente relacionados ao conteúdo de polissacarídeos específicos, de interesse comercial da cultura de Aloe vera. Esses teores, por sua vez, foram propiciados pelos melhores valores de IAF, TCA, IMMF e IMMS, todos observados aos 270 dias de cultivo, ratificando a significância do fator tempo e da dose de 210 ppm de nitrogênio no cultivo dessa espécie vegetal. / Aloe vera (L.) Burm. f., family Asphodelaceae, worldwide renowned and explored by pharmaceutics and cosmetics industries due to its phenolics bearing medicinal principles and mainly to the specific polysaccharides present in the gel, was submitted to two interlinked experiments. The first one refers to apical shoot micropropagation evaluating different disinfection treatments of the explants, the in vitro bud multiplication and ex vitro acclimatization of the microplants. The second one refers to cultivation in greenhouse of the micropropagated plants in washed sand and irrigated with nutritive solution, in the presence of three nitrogen rates (105, 210 and 315 ppm); the plant material was harvested at 90-, 180- and 270-day. All data were statistically analyzed. The effects of nitrogen were evaluated on the content of the macronutrients, the following micronutrients: B, Cu, Fe, Mn and Zn and total soluble proteins, reducing sugars, total soluble sugars; the growth of the Aloe vera plants was measured through the foliar area index, the rate of liquid assimilation, rates of relative and absolute growth and increases in the fresh and dry weights. In regards to micropropagtion, the efficiency of the disinfection process was increased by 40% when the plants harvested in the field were previously washed either with sodium hypochloride (0.5% active chlorine) solution or sodium dichloroisocyanurate (Sumaveg®) 0.66% w.v-1 solution and the apical shoots explants were afterwards alternatively treated with the two disinfectants. The multiplication phase in MS medium showed a rate of 1:5.3 of microplant production at each 30-day interval with a production of 40.495 microplants out of the 136 initial disinfected apical shoots. The microplants were classified as small, medium and large plants and acclimatized in polyethylene trays bearing 64 cells with 40 cm3 of substrate each cell, a 50% saving in terms of substrate amount and free space in the greenhouse equipped with micro-aspersion irrigation, pad-house and air exhaustion systems and also in the transport of the acclimatized microplants. In regards to the effect of nitrogen rates on the development of Aloe vera plants, besides the fact that the best responses were observed either to 105 ppm or 315 ppm nitrogen by some variables, at 210 ppm nitrogen rates the best result was obtained for total soluble sugars (504.21 mg.g-1DW); the sugars are directly related to specific polysaccharides of Aloe vera and are of great importance for the industries. On the other hand, these values were favored by the best values reached by the physiological variables studied in this work at 270-day validate the significance of the time factor and the 210 ppm N rates in the Aloe vera production system.

Ryska gerundier i översättning till och från svenska : Implicita och explicita betydelserMellquist, Simone January 2017 (has links)
Swedish lacks gerunds and is therefore suitable for studying implicit meanings of Russian gerunds that are forced to become explicit in Swedish translations. The present contrastive parallel corpus study explores translation correspondences in both directions. It is shown that constructions with finite verbs of perfective aspect followed by imperfective gerunds largely correspond to Swedish absolute withconstructions (= Swedish med-constructions). Another finding is the insertion of extra gerunds in connection with translation of Swedish locative constructions. A classification of Swedish explicit time markers corresponding to converb constructions is structured according to time relations (taxis relations): perfective aspect converbs show a clear correspondence to anterior markers, and imperfective converbs correlate with simultaneity markers. Contextual secondary meanings like means, purpose, cause, consequence are analyzed and various structures are found

Quantitative high resolution Fourier transform infrared spectroscopy / Spectroscopie infrarouge quantitative à haute résolution par transformée de FourierVander Auwera, Jean 27 May 2004 (has links)
Our work falls within the field of high resolution spectroscopy of gas phase molecules in the far-, mid- and near-infrared ranges. Its guiding line are absorption spectral intensities, dealt with experimentally and theoretically. In particular, we developed in our laboratory the field of intensities measurements of vibration-rotation lines using Fourier transform spectrometers, with a precision of about 0.5 % and an accuracy of 2-4 % for chemically stable species. We study chemically stable (CO2, N2O, C2H6, OCS, C2H2) and unstable (HOCl, HCOOH et HNO3) compounds. We also measure infrared absorption cross section spectra for CFC replacements. Some of our measured intensities, of direct interest for the study of planetary atmospheres, are now incorporated in international spectroscopic databases. Others are used to develop global theoretical models of molecules, in relationship with intra-molecular dynamics./Nos travaux de recherches relèvent de la spectroscopie à haute résolution de molécules en phase gazeuse dans les domaines de l’infrarouge lointain, moyen et proche. Ils ont pour ligne directrice les intensités spectrales d’absorption, abordées expérimentalement et théoriquement. Nous avons en particulier développé dans notre laboratoire le domaine de la mesure d’intensités d’absorption de raies de vibration-rotation à l’aide de spectromètres à transformée de Fourier. Nous réalisons ces mesures avec une précision d’environ 0.5 % et une exactitude d'environ 2-4 % pour les espèces chimiquement stables. Nous étudions des composés chimiquement stables (CO2, N2O, C2H6, OCS, C2H2) et instables (HOCl, HCOOH et HNO3). Nous mesurons également des spectres de sections efficaces d’absorption infrarouge pour des substituts des chlorofluorocarbures (CFC). Certaines de nos mesures d’intensité, d’intérêt direct pour l’étude d’atmosphères planétaires, sont aujourd’hui incorporées dans les bases de données spectroscopiques internationales. D’autres sont utilisées pour développer des modèles théoriques globaux de molécules, en liaison avec la dynamique intramoléculaire. / Agrégation de l'enseignement supérieur, Orientation sciences / info:eu-repo/semantics/nonPublished

Description morpho-syntaxique du nââ numèè (langue de l'extrême-Sud, Nouvelle-Calédonie)Wacalie, Fabrice Saiqë 08 November 2013 (has links)
Cette thèse porte sur la description morpho-syntaxique du nââ numèè, langue de l’extrême-Sud de la Nouvelle-Calédonie, parlée par moins de 1 000 locuteurs dans les tribus de Touaourou et de Goro dans la commune de Yaté et de l’île Ouen dans la commune du Mont-Dore.Dans la première partie, l’auteur aborde les faits sociaux qui ont fait de la région du Grand Sud l’une des plus impactés par les guerres traditionnelles, la colonisation, l’évangélisation, la construction du barrage de Yaté et plus récemment, l’exploitation minière.Dans la deuxième partie, l’auteur procède à l’identification des phonèmes de la langue. Ensuite, il effectue une comparaison entre le système consonantique, vocalique et tonal ainsi établi et celui réalisé par Rivierre dans les années 70. Cette analyse d’écart lui permet de mettre en exergue les évolutions phonologiques subies par la langue en presque quarante ans. Pour définir les différents morphèmes de la langue, l’auteur utilise la méthode traditionnelle dite « distributionnelle ». Il propose ensuite une catégorisation des lexèmes.Dans la troisième partie, l’auteur traite des procédés morphologiques utilisaient en dérivation et en composition.Dans la quatrième partie consacrée à la syntaxe, l’auteur expose le syntagme nominal avec les différents modes et types de détermination. Cette partie comprend également un exposé des substituts du nom, des déictiques et du système numéral. Puis, l’auteur propose une description du syntagme verbal avec en point d’orgue, l’analyse des marqueurs aspecto-temporels et les constructions sérielles. Dans la partie dédiée aux circonstants, l’auteur s’intéresse au système d’orientation développé et les différents cadres référentiels utilisaient (absolus et relatifs).Dans la dernière partie, l’auteur expose les différents types d’énoncés (simples, complexes et marqués). / This thesis deals with the morpho-syntactic description of Nââ Numèè, a language of the far south of New Caledonia, spoken by fewer than 1,000 speakers in the tribes of Touaourou and Goro in the town of Yate and the isle Ouen in the town of Mont-Dore.In the first part, the author explains the social facts which led to the great southern region being one of the most affected by traditional wars, colonization, evangelization, the construction of the dam at Yate and more recently, mining.In the second part, the author will identify the phonemes of the language. Then a comparison will be made between the consonant, vowel and tonal system thus established and made by Rivierre in the 1970s. This gap analysis allows the author to highlight the phonological changes in the language over almost forty years. The author then uses the traditional "distributional" method to define the different morphemes of language before proposing a categorization of lexemes.In the third part, the author deals with morphological processes used in derivation and in composition. In this chapter, it is interesting to see the increased use of verbal classifiers.In the fourth section dealing with syntax, the author offers a description of the nominal phrase with the modes and types of determination. This part also includes a presentation of the nominal substitutes, deictic and numeral systems. Then, the author describes the verbal phrase with special focus on the analysis of the aspect and temporal markers and serial verbs. In the part dedicated to the circonstants, the author focuses on the orientation system developed and the various repositories spaces used (absolute and relative).In the last part, the author exposes the different types of clauses (simple, complex and marked).

基於最小一乘法的室外WiFi匹配定位之研究 / Study on Outdoor WiFi Matching Positioning Based on Least Absolute Deviation林子添 Unknown Date (has links)
隨著WiFi訊號在都市的涵蓋率逐漸普及,基於WiFi訊號強度值的定位方法逐漸發展。WiFi匹配定位(Matching Positioning)是透過參考點坐標與WiFi訊號強度(Received Signal Strength Indicator, RSSI)的蒐集,以最小二乘法(Least Squares, LS)計算RSSI模型參數;然後,利用模型參數與使用者位置的WiFi訊號強度,推估出使用者的位置。然而WiFi訊號強度容易受到環境因素影響,例如降雨、建物遮蔽、人群擾動等因素,皆會使訊號強度降低,若以受影響的訊號強度進行定位,將使定位成果與真實位置產生偏移。
為了降低訊號強度的錯誤造成定位結果的誤差,本研究嘗試透過具有穩健性的最小一乘法( Least Absolute Deviation, LAD)結合WiFi匹配定位,去克服WiFi訊號易受環境影響的特性,期以獲得較精確的WiFi定位成果。研究首先透過模擬資料的建立,測試不同粗差狀況最小一乘法WiFi匹配定位之表現,最後再以真實WiFi訊號進行匹配定位的演算,並比較最小一乘法WiFi匹配定位與最小二乘法WiFi匹配定位的成果差異,探討二種方法的特性。
根據本研究成果顯示,於模擬資料中,最小一乘法WiFi匹配定位相較於最小二乘法WiFi匹配定位,在面對參考點接收的AP訊號與檢核點接收的AP訊號強度含有粗差的情形皆能有較好的穩健性,且在參考點接收的AP訊號含有粗差的情況有良好的偵錯能力。而於真實環境之下,最小一乘法WiFi匹配定位之精度也較最小二乘法WiFi匹配定位具有穩健性;在室外資料的部份,最小一乘法WiFi匹配定位之精度為8.46公尺,最小二乘法WiFi匹配定位之精度為8.57公尺。在室內資料的部份,最小一乘法WiFi匹配定位之精度為2.20公尺,最小二乘法WiFi匹配定位之精度為2.41公尺。 / Because of the extensive coverage of WiFi signal, the positioning methods by the WiFi signal are proposed. WiFi Matching Positioning is a method of WiFi positioning. By collecting the WiFi signal strength and coordiates of reference points to calculate the signal strength transformation parameters, then, user’s location can be calculated with the LS (Least Squares). However, the WiFi signal strength is easily degraded by the environment. Using the degraded WiFi signal to positioning will produce wrong coordinates.
Hence this research tries to use the robustness of LAD (Least Absolute Deviation) combining with WiFi Matching Positioning to overcome the sensibility of WiFi signal strength, expecting to make the result of WiFi positioning more reliable. At first, in order to test the ability of LAD, this research uses simulating data to add different kind of outliers in the database, and checks the performance of LAD WiFi Matching Positioning. Finally, this research uses real data to compare the difference between the results of LAD and LS WiFi Matching Positioning.
In the simulating data, the test result shows that LAD WiFi Matching Positioning can not only have better robust ability to deal with the reference and check points AP signal strength error than LS WiFi Matching Positioning but also can detect the outlier in the reference points AP signal strength. In the real data, LAD WiFi Matching Positioning can also have better result. In the outdoor situation, the RMSE (Root Mean Square Error) of LAD WiFi Matching Positioning and LS (Least Squares) WiFi Matching Positioning are 8.46 meters and 8.57 meters respectively. In the indoor situation, the RMSE (Root Mean Square Error) of LAD WiFi Matching Positioning and LS (Least Squares) WiFi Matching Positioning are 2.20 meters and 2.41 meters respectively.
