A floricultura no Brasil, que inclui flores e plantas ornamentais, vem gradualmente crescendo como atividade econômica. Considerando a carência de informações sobre as exigências nutricionais de roseiras, nas condições de produção no Brasil, objetivou-se: a) determinar a curva de crescimento pelo acúmulo de matéria seca de plantas cultivadas em solo, em ambiente protegido; b) estudar a técnica de subtração de nutrientes, para o desenvolvimento e a caracterização dos sintomas de deficiência da cultura cultivada em solução nutritiva em casa de vegetação; e c) avaliar as concentrações e os acúmulos de nutrientes, durante os experimentos em solo e em solução nutritiva. Plantas de Rosa sp. cultivares Vegas e Tineke, foram avaliadas aos 60, 88, 116, 144, 172, 200, 228 e 256 dias após o transplantio, em um delineamento inteiramente casualizado, no período de novembro de 2005 a setembro de 2006. Plantas do cultivar Vegas, foram cultivadas, em casa de vegetação, com solução nutritiva completa e solução com omissão de N, P, K, Ca, Mg, S, B, Cu, Fe, Mn e Zn, em delineamento inteiramente casualizado, no período de agosto a novembro de 2007. A produção de material seco da parte aérea foi crescente durante o período analisado para os cultivares Vegas e Tineke. As plantas do cultivar Vegas apresentaram uma demanda crescente dos macronutrientes e um acúmulo máximo de B, Cu, Fe, Mn e Zn entre 166 e 230 dias após o transplantio. O cultivar Tineke apresentou uma demanda crescente por N, P, K, Ca, S, B, Cu, Fe, Mn e Zn. Os sintomas de deficiência nutricional foram caracterizados, de acordo com os sintomas típicos para a maioria das culturas, exceto para o Cu e Mn. A omissão dos nutrientes afetou a produção de material seco das folhas velhas, folhas novas, caule, rosas e raízes. As concentrações dos nutrientes nas folhas velhas das plantas desenvolvidas em solução nutritiva completa foram: 20,79; 2,52; 22,83; 17,19; 3,30 e 1,37 g kg-1, respectivamente, para N, P, K, Ca, Mg e S e, 148,64; 0,63; 151,40; 129,00 e 9,83 mg kg-1 respectivamente para B, Cu, Fe, Mn e Zn. A ordem de importância dos nutrientes, representada pelo acúmulo nas folhas velhas, foi: K > N > Ca > Mg >P > S > Fe > B > Mn > Zn > Cu e nas flores foi: N > K > P > Ca > Mg > S > Fe > Mn > B > Zn > Cu. / Considering the little information on roses mineral nutrition at production conditions in Brazil, this study objectives were: a) to determine plants dry matter accumulation curve, grown in soil under protected conditions; b) to study nutrient absence technique for the development and deficiency symptoms characterization of a culture grown on nutrient solution in greenhouse and c) to evaluate the contents and nutrients accumulations, during the soil and nutrient solution experiments. Rosa sp. cultivar Vegas and Tineke plants were collected and evaluated to the 60, 88, 116, 144, 172, 200, 228 and 256 days after transplanting in greenhouse condition, in a completely randomized design, from November of 2005 to September of 2006. Cultivar Vegasplants grown in greenhouse, with complete nutrient solution and solution with N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn omission, in a completely randomized design, from August to November of 2007. Aerial part dry matter production increased during the analyzed period to cultivar Vegas and Tineke. Vegascultivar plants presented an increasing demand of the macronutrients and a maximum accumulation of B, Cu, Fe, Mn and Zn between 166 and 230 days after the transplanting. Cultivar Tineke presented an increasing demand for N, P, K, Ca, S, B, Cu, Fe, Mn and Zn. The nutrient deficiency symptoms were characterized in accordance with typical symptoms for the majority of cultures, except for the Cu and Mn. The nutrients omission affected dry matter production of old leaves, young leaves, stem, flowers and roots. The nutrient contents in the old leaves of plants grown in complete nutrient solution were: 20,79; 2,52; 22,83; 17,19; 3,30 and 1,37 g kg-1, respectively, for N, P, K, Ca, Mg and S and, 148,64; 0,63; 151,40; 129,00 and 9,83 mg kg-1, respectively, for B, Cu, Fe, Mn and Zn. The nutrients importance order, represented for old leaves accumulation were: K > N > Ca > Mg > P > S > Fe > B > Mn > Zn > Cu and, in flowers were: N > K > P > Ca > Mg > S > Fe > Mn > B > Zn > Cu.

In my essay I will discuss the role of the main character, Miss Emily, in the short story "A Rose for Emily" by William Faulkner. The short story was written in 1930 and takes place in the small town of Jefferson, in the south of the USA. Miss Emily is the only person remaining of the Grierson family, a family seen as mighty, as it used to be wealthy and had a prominent position in the town, and therefore she considers herself as finer than the other townspeople. As a result, she never marries and keeps to herself most of the time. The story stretches over most of Miss Emily‟s life and the narrator focuses on her. When she in the end dies, it is revealed that she had poisoned her lover and slept next to the dead body for forty years. In this essay I suggest that Miss Emily is imaged as a goddess and I will try to show evidence for that by pointing out religious references in the text as well as by discussing the important role of the narrator. I will argue that due to the Grierson family‟s history being of importance to the town, the prominence of Miss Emily‟s looks, and the way she acts imply that she is seen by the townspeople as a goddess. Moreover, Miss Emily‟s relationship with Homer Barron and the description of her house will be analyzed to strengthen the idea that Miss Emily could be linked to divinity. In my view, if Miss Emily is perceived as a goddess, she is bound to emerge as more than a mentally disturbed woman who killed her lover.

In order to facilitate design and maintenance of such a large and complex site as a nuclear power plant, all system functions must be described in a stringent way. In the past, these descriptions consisted of text documents and logical diagrams, but today there are an increasing number of object-oriented programs available on the market which might be used for this purpose. This Master Thesis has made a closer study of one of these programs named Rational Rose. The principal of the program is to facilitate software design and development, not to create models of plants. However, using the program the same way as developing software, specifying actors then gradually extend the model with use cases, use cases diagrams etc, the same methods can be used when modelling plants. During this Master Thesis most of the time has been spent developing, structuring and classifying the functions composing the Feed Water Backup System of the reactor named Oskarshamn 3. A considerable amount of time was also spent to find a general structure for typical motor and valve circuits in the plant, which are also applicable for the configuration of the Feed Water Backup System. This general structure will then be used to support maintenance and to get faster decisions when new systems are designed. Effectuating the modernization of the nuclear power plants in Sweden, an ever- increasing use of highly software intensive systems will be introduced, which also leads to the need of finding other ways to describe those systems. A suitable method is to use Rational Rose, where the entire process, from description to final product, will be done in an integrated way. Use cases are generated and together with their related documentation they will form the description of the desired system functions.

A phytochemical investigation on methanolic extract of roots of yellow rose led to the isolation of a catechin gallate. The crude extract first underwent fractionation using petroleum ether, chloroform, ethylacetate, butanol with water as solvents in their respective order. The emerging solvent fractions were subjected to further separation using lipophilic sephadex (LH-20), and silica gel column chromatography to isolate pure compounds. Analytical thin layer chromatography (TLC) was used to confirm the presence of a catechin in butanol fraction. Purified catechin compound was subjected to 2,2-diphenyl-1-picrylhydrazyl (DPPH) experiment to determine its Radical Scavenging Capacity, which was found quite promising. Chemical structure of purified compound was established by using Nuclear Magnetic Resonance (NMR) and Mass Spectrometry (MS) experiments.
