With this, it is necessary to handle them correctly in order to favor the growth of the culture. In this study, the objective was to evaluate the silvicultural and physiological characteristics, the levels of nutrients in the leaves, and the microbiological activity of the eucalypts rhizosphere, submitted to methods of control of the Urochloa species. The experiment was conducted in a protected environment, used a randomized outline with five repetitions, in a factorial scheme (5 x 2) +1, with five groups of Urochloa spp (no control; chemical control maintain the waste of weeds in the pot; chemical control removing the waste of weeds from the pot; mechanical control maintaining the weed waste in the pot; and mechanical control removing the weed waste from the pot), two species of weed plants (U. brizantha e U. decumbens) and a control (eucalypts without a weed plant). The experimental units had pots with 110 dm3 with one plant of eucalypts and 10 plants of U. brizantha or of U. decumbens, 50 plants -2. The growth of eucalypts was measured every 10 days using the height of the plant (cm) and root collar diameter. At the days 18, 38, 48 and 105, after the transplanting (DAT), the photosynthetic level, the transpiration level, the consumption of CO2, the stomatal conductance, the efficiency in the use of water, the concentration of internal CO2, the ratio between the concentrations of internal carbon and of atmospheric carbon, and the leaf temperature were evaluated. After 107 DAT, leaves, stem, branches and the root system of the eucalyptus were collected separately for the determination of dry matter and of the foliar area. Foliar samples of the eucalypts were also collected for the ascertainment of the level of nutrients and ground rhizosphere for the ascertainment of the microbiological activity. The results were submitted to the Dunnett test, with a 5% probability and only the management had significant relevance for the silvicultural, physiological, basal respiratory level, and the microbiological biomass carbon variables. The eucalypts plants in competition presented stagnation in the root collar diameter at 20 DAT and decreasing photosynthetic levels at 48 DAT, indicating the necessity of controls, made at 50 DAT. The height of the plants was not affected by the presence of the competitor species until the control, however, after the control the treatments where there was chemical control (keeping or removing the residues of weeds of the species Urochloa in/from the pot) and in the treatment where there was mechanical control keeping the weed residues of Urochloa spp. in the pot, the eucalypts presented greater increase in height, deferring from the other arrangements and the control. Living with the species Urochloa for 107 days affected the root collar diameter, influencing negatively in the dry matter of the eucalypts. The same was observed for the foliar area, photosynthetic level and foliar levels of nitrogen, manganese and iron of the eucalypts plants. In the presence of U. brizantha, the eucalypts presented smaller foliar levels of phosphorus for the chemical management, keeping or removing the weed residues of the competitor agents, and higher foliar levels of copper in the chemical treatment, keeping the weed residues of Urochloa spp. in the pot. There was no significant impact in the microbiota of the soil because of the plants. One concludes that, the presence of the species Urochloa, for 107 days, affects the silvicultural and physiological variables negatively. A difference between chemical and mechanical management of the plants was not observed, maintaining or not weed residue in the pot. This shows that all of the controls were effective and did not cause disturbances to micro-organisms of the eucalypts. / A interferência das espécies Urochloa brizantha e Urochloa decumbens pode causar danos irreversíveis as plantas de eucalipto. Com isso, torna-se necessário manejá-las corretamente a fim de favorecer crescimento da cultura. Neste trabalho, objetivou-se avaliar o crescimento inicial, as características silviculturais, as características fisiológicas, os teores de nutrientes nas folhas e a atividade microbiológica da rizosfera do eucalipto submetido a métodos de controle das espécies de Urochloa. O experimento foi conduzido em ambiente protegido, em DBC com cinco repetições, no esquema fatorial (5 x 2) +1, sendo cinco manejos de Urochloa spp. (sem controle; controle químico mantendo os resíduos da capina no vaso; controle químico retirando os resíduos da capina do vaso; controle mecânico mantendo os resíduos da capina no vaso e controle mecânico retirando os resíduos da capina do vaso), duas espécies de plantas daninhas (U. brizantha e U. decumbens) e uma testemunha (eucalipto isento de planta daninha). As unidades experimentais consistiram de vasos de 110 dm3 com uma planta de eucalipto e dez plantas de U. brizantha ou de U. decumbens, 50 plantas m-2. O crescimento do eucalipto foi mensurado a cada 10 dias por meio da altura de planta (cm) e do diâmetro do coleto (mm). Aos 18, 38, 48 e 105 dias após o transplantio (DAT) avaliou-se a taxa fotossintética, a taxa transpiratória, o consumo de CO2, a condutância estomática, a eficiência do uso de água, a concentração de CO2 interno, a razão entre as concentrações de carbono interno e de carbono atmosférico e a temperatura foliar. Após 107 DAT, coletaram-se separadamente folhas, caule, ramos e o sistema radicular do eucalipto para a determinação da matéria seca e área foliar. Amostras foliares do eucalipto também foram coletadas para a determinação dos teores de nutrientes e solo rizosférico para determinação da atividade microbiológica. Os resultados foram submetidos ao teste Dunnett, a 5% de probabilidade, sendo que apenas o manejo apresentou significância para as variáveis silviculturais, fisiológicas, taxa respiratória basal e o carbono da biomassa microbiana. Para a análise de nutrientes e quociente metabólico observou-se interação significativa para manejos e espécies. As plantas de eucalipto em competição apresentaram estagnação do diâmetro do coleto aos 20 DAT e decréscimos nas taxas fotossintéticas aos 48 DAT, indicando a necessidade da realização dos controles, que foram realizados aos 50 DAT. A altura de plantas não foi afetada pela presença das espécies competidoras até o momento do controle controle, porém, após o mesmo os tratamentos onde houve controle químico (mantendo ou retirando os resíduos da capina das espécies de Urochloa do vaso) e no tratamento onde houve controle mecânico mantendo os resíduos da capina das Urochloa spp. no vaso, o eucalipto apresentou maior ganho em altura, diferindo dos demais manejos e da testemunha. A convivência das espécies de Urochloa por 107 dias afetou o diâmetro do coleto, influenciando negativamente na matéria seca do eucalipto. O mesmo foi observado para a aérea foliar e taxa fotossintética e teores foliares de nitrogênio, manganês e ferro das plantas de eucalipto. Na presença de U. brizantha, o eucalipto apresentou menores teores foliares de fósforo para os manejos químicos, mantendo ou retirando os resíduos da capina dos agentes competidores, e maiores teores foliares de cobre no tratamento químico, mantendo os resíduos da capina de Urochloa spp. no vaso. Não houve impacto significativo na atividade da microbiota do solo pelos manejos. Conclui-se que a presença das espécies de Urochloa, por 107 dias, afetou negativamente as variáveis silviculturais e fisiológicas. Não observou-se diferenças entre os manejos químico e mecânico, mantendo ou retirando os resíduos da capina das espécies de Urochloa, evidenciando que todos os controles se mostraram eficientes e não causaram distúrbios aos micro-organismos da rizosfera do eucalipto.

Foram abertas seis trincheiras em cada sistema avaliado, para realização do estudo morfológico pelo método do perfil de manejo. Com base na identificação das unidades morfologicamente homogêneas encontradas na descrição do perfil de solo, foram realizadas amostragens para análises de granulometria, densidade de partículas, densidade do solo, estabilidade de agregados e porosidade total, além de análises químicas de rotina. As análises morfológicas, físicas e químicas permitiram concluir que as principais modificações químicas, físicas e morfológicas verificadas nos tratamentos com a cultura de cana-de-açúcar no sistema tradicional e com trigo no sistema de plantio direto restringiram-se aos primeiros 45 cm dos perfis. Os tratamentos com a cultura de cana-de-açúcar no sistema tradicional de manejo e com trigo no sistema plantio direto apresentaram redução entre 15 e 20% na porosidade, enquanto a macrofauna de invertebrados desempenhou importante papel na formação de canais e no transporte de materiais para dentro dos perfis pedológicos estudados. O método do perfil de manejo permitiu uma adequada percepção das principais alterações encontradas nos tratamentos estudados / Abstract: The study was carried in 2002, in the north of Paraná, Rolandia, in Jaú Farm and had how objective asses the morphological modification, physicals and chemistries about a clayey Oxisols, comparing the conventional systems of sugar cane used by Rolandia's Cooperative Agriculture and the systems of no tillage with wheat culture in rotation with others years cultures, both with eight years of successes cultivations, using how reference a vegetation native area localized beside valuated systems. Were opened six trenches in each valuated system, for carrying about morphological study by method of Cropping Profile Method. Based on the identification of the units morphologically homogeneous found in the description about the profile of soil, were realized samples for analysis of soil texture, particle density, bulk density, soil total porosity, distribution of water stable aggregate, besides chemistries systems of routine. The morphological analyzes, physicals and chemistries, helped to conclude that the mains chemistries, physicals and morphological changed checked in treatment with the sugar cane culture in the traditional systems and with trig in the systems of no tillage restricting in the first forty-five centimeters of the profiles. The treatments with the conventional systems of sugar cane and with wheat in the no tillage systems presented a reduction between fifteen and twenty per cent in soil porosity, while the soil fauna of invertebrates played an important role in the formation of ducts and in the transport of materials into the profiles studied. The Cropping Profile Method helped to understand an apropriate notion about the mains changed found in the treatment studied. / Doutorado / Agua e Solo / Doutor em Engenharia Agrícola

The main goal of this diploma thesis is to analyse the customer satisfaction with the loyalty program Active beauty and to propose some improvement suggestions. The theoretical part is focused on the issue of the customer care, customer satisfaction and loyalty. In the following part is described the situation in the retail market and chemist's market in the Czech Republic. Subsequently is introduced the loyalty program Active beauty and evaluated results of the research.

This work deals with customer loyalty and loyalty programmes in areas of buying chemist goods, clothing, footwear and groceries. The main objective of this work is to compare the approach of English and Czech customers to loyalty programmes in these areas. The intention of the analysis is to discover whether the approach to loyalty programmes in these two countries varies and what are the major differences. Does using a loyalty programme really affect customer loyalty? Who are more loyal, Czech or English customers? The aim is also to find out how customers use their loyalty programs, what kind of rewards are the most attractive for them and what personal information are they willing to provide when they sign up for loyalty programmes. The analysis also aims to pose these same questions to multi-brand partnership programmes and also mobile applications. This work can therefore benefit companies operating in both Czech and English markets to adapt their loyalty programs to be most effective.

The registered midwives are engaged in continuous health education lessons In antenatal visits, discouraging antenatal clients from using hannful traditional and cultural practices in an attempt to preserve pregnancy to tenn. Despite the registered midwives' efforts, the clients continue to use hannful cultural methods, which are life-threatening to both the mother and the foetus In utero. The prenatal clients perceive the registered midwives as not being sensitive to their culture. The results of this study revealed that health education in antenatal clinics should be collaborative: that is, the people who have influence over the clients' pregnancy, like me mother-in-law, the traditional practitioners, cUents and their family members, should be involved by the midwives during the preparation of pregnancy lessons and health education lessons on how to preserve pregnancy to term according to· scientifically proven methods. / Health Studies / M.A. (Health Studies)
