Resumo: Os tecidos vegetais tendem a ficar mais tenros em sistemas de produção onde maior fertilização com nitrogênio (N) é exigida, favorecendo o auto-sombreamento das plantas; entretanto, com aplicação de silício (Si), há melhoria na arquitetura foliar, reduzindo tal fenômeno. Objetivou-se, com este estudo, avaliar os efeitos da adubação nitrogenada e sua interação com a adição de Si na forma de escória de siderurgia nos atributos químicos do solo, na nutrição e na produtividade da cana-planta. O experimento foi instalado em condições de campo no município de Jaboticabal, SP, Brasil. Os tratamentos foram dispostos em esquema fatorial 5x2, sendo cinco doses de N (0, 30, 60, 90 e 120 kg ha-1) com Si (escória de siderurgia) e sem adição de Si (calcário), em delineamento em blocos ao acaso, com quatro repetições. Os atributos químicos do solo não diferiram com a aplicação de calcário ou de escória após 99 dias da aplicação dos materiais corretivos tampouco não houve mobilidade das bases no perfil do solo. A adubação nitrogenada com ou sem adição de Si não afetou as variáveis de desenvolvimento da cana-planta. Os maiores acúmulos de N, P, K, Mg, S, Cu e Zn ocorreram no colmo, ao passo que os maiores acúmulos de Ca, B, Fe, Mn e Si apresentaram-se nas folhas. Os elementos mais extraídos pela cana-planta (variedade RB855156) foram Si, K e N. Houve efeito da adubação nitrogenada na produtividade da cana-planta quando associada à adição de Si na forma de escória, ocorrendo aumento de 15 t ha-1 na produção de colmos industrializáveis. O uso da adubação nitrogenada incrementou o teor de sacarose e fibra de forma linear, entretanto, não houve efeito da escória nas variáveis tecnológicas da cana-planta. De modo geral, a adubação nitrogenada associada à adição de Si na forma de escória mostra-se adequada ao cultivo da cana-planta / Abstract: In cases where more N fertilization is applied, plant tissues are tender and self-shading of the plants may result. Moreover, Si is important because it promotes improved leaf architecture and reduces self-shading. The objective of this study was to evaluate the effect of nitrogen with addition of Si as slag in soil chemical properties, nutrition and cane plant yield. The experiment was carried out in Jaboticabal, Sao Paulo State, Brazil with five N rates: 0, 30, 60, 90, and 120 kg ha-1 with Si (slag) and without Si (lime), in a randomized block with four replications. The soil chemical properties did not differ with the application of lime or slag in 99 days after application neither any mobility of bases in the soil profile was verified. Nitrogen fertilization with or without addition of Si did not affect the growth parameters of the cane plant. Accumulation of N, P, K, Mg, S, Cu and Zn mostly occurred in the stalk, while the highest Ca, B, Fe, Mn and Si accumulation were found in the leaves. Si, K and N were the most elements extracted by the cane plant (variety RB855156). No significant effects of N fertilization on cane plant yield; however, when associated with Si as slag, there was an increase of 15 t ha-1 of stalks. Nitrogen fertilizer increased the sucrose content and fiber linearly, however, no effect of adding slag in the technological variables of the cane plant. In general, nitrogen associated with Si added in the form of slag proved to be adequate for the cultivation of cane plant / Orientador: Renato de Mello Prado / Coorientador: Wanderley José de Melo / Banca: José Lavres Junior / Banca: Francisco Maximino Fernandes / Banca: Edson Luiz Mendes Coutinho / Banca: Miguel Ângelo Mutton / Doutor

Extensive published literature shows that hydrated lime improves Hot Mix Asphalt (HMA) durability. Its impact on the environmental impact of HMA has not been investigated. This paper presents a comparative Life Cycle Assessment (LCA) for the use of HMA without hydrated lime (classical HMA) and with hydrated lime (modified HMA) for the lifetime of a highway. System boundaries cover the life cycle from cradle-to-grave, meaning extraction of raw materials to end of life of the road. The main assumptions were: 1. Lifetime of the road 50 years; 2. Classical HMA with a life span of 10 years, maintenance operations every 10 years; 3. Modified HMA with an increase in the life span by 25%, maintenance operations every 12.5 years. For the lifetime of the road, modified HMA has the lowest environmental footprint compared to classical HMA with the following benefits: 43% less primary total energy consumption resulting in 23% lower emissions of greenhouse gases. Partial LCAs focusing only on the construction and/or maintenance phase should be used with caution since they could lead to wrong decisions if the durability and the maintenance scenarios differ. Sustainable construction technologies should not only consider environmental impact as quantified by LCA, but also economic and social impacts as well. Avoiding maintenance steps means less road works, fewer traffic jams and hence less CO2 emissions.

This thesis presents the results of a series of undrained cyclic triaxial tests carried out on four lime-cement stabilized specimens and clay specimen. The shear resistance degradation rate of lime-cement column subjected to cyclic loading simulated from heavy truck was investigated based on stress-controlled test. The influence of lime and cement on the degradation rate was investigated by comparing the behavior of stabilized kaolin and unstabilized kaolin with similar initial condition. The results indicate an increase in degree of degradation as the number of loading cycles and cyclic strain increase. It is observed that the degradation index has approximately a parabolic relationship with the number of cycles. Generally adding lime and cement to the clay will increase the degradation index which means lower degree of degradation. The degradation parameter, t has a hyperbolic relationship with shear strain, but it loses its hyperbolic shape as the soil getting stronger. On the other hand, for unstabilized clay an approximate linear relationship between degradation index and number of cycles was observed and the degradation parameter has a hyperbolic shape with the increase number of cycles. It was also observed that the stronger the material was, the lesser pore pressure developed in the lime-cement stabilized clay.

The aim of my master's project is to design a new building of kindergarden with nearly zero energy consumption. The project consists of three main parts. The first part is to create project documentation. The building is designed regarding to architectural expression. The kindergarden is split into two departments each for twenty children. It is single storey building with saddle roof. It is based on concrete foundation and under them there is foam glass. External walls are made of sand-lime blocks which are insulated with a contact thermal insulation system. The second part is to assess the energy performance of the building and usage of energy from renewable sources. The building uses ground source heat pump as a heating, air is provided by mechanical ventilation with heat recovery and eleckricity is partly provided by a photovoltaic system. The last part of master's project evaluates the building by the method of multi–criteria analysis. For this evaluation I used national method SBToolCZ.
