2. Avaliação comparativa da pegada de carbono de margarina e manteiga produzidas no Sul do Brasil
RESUMO A avaliação de ciclo de vida (ACV) é uma técnica de estimativa de impactos ambientais, como emissão de gases de efeito estufa (CO2eq), para geração de produto ou realização de processo. O objetivo deste estudo foi estabelecer a pegada de carbono para a produção da margarina e da manteiga com uso das normas ISO e PAS aplicadas a uma empresa

3. Combined effects of low light and water stress on Jatropha curcas L. promotes shoot growth and morphological adjustment
Jatropha curcas (physic nut) is a plant with economic and pharmaceutical uses. Basic studies on the influence of environmental factors on the early development of J. curcas are important for improving farming techniques and increasing productivity. This study investigated the adjustments of J. curcas to the environmental factors of drought and light stress i

4. Modeling the microbial growth of two Escherichia coli strains in a multi-substrate environment
The microbial growth in multi-substrate environments may be viewed as an optimal resources allocation problem. The optimization aims at maximizing some biological objective like the biomass growth. The models developed using this hypothesis are called "cybernetic" and they represent the complex cell structure as an optimizing function that regulates the intr

5. Input of sugarcane post-harvest residues into the soil
Sugarcane (Saccharum spp.) crops provide carbon (C) for soil through straw and root system decomposition. Recently, however, sugarcane producers are considering straw to be removed for electricity or second generation ethanol production. To elucidate the role of straw and root system on the carbon supply into the soil, the biomass inputs from sugarcane straw

6. Aspectos fisiológicos e da produção do arroz em resposta ao silício / Physiological and productive aspects of rice plants according to silicon supplying
The objective of this study was to analyze the role of supplemental silicon (Si) in the biomass accumulation and grain yield of rice (Oryza sativa L.). Different experiments were carried out in which wild rice plants (japonica subsp. Oochikara - WT) and mutant defective for the absorption of Si - lsi1 (Low silicon rice 1) were raised under hydroponics condit

8. Caracterização da capacidade fotossintética e da condutância estomática em sete clones comerciais de Eucalyptus e seus padrões de resposta ao déficit de pressão de vapor / Photosynthetic capacity and stomatal conductance characterization for seven commercial Eucalyptus clones and their variation due to vapor pressure deficit
This study aimed to characterize the physiological variables related to photosynthesis, in seven commercial Eucalyptus clones with high productivity, by evaluating maximum photosynthetic capacity (Amax), and the response of photosynthesis (A), stomatal conductance (gs) and transpiration (E) to Vapor Pressure Deficit (VPD). A trial was installed in 2004, at E

9. Capacidade de regeneração da floresta tropical amazônica sob deficiência nutricional: resultados de um estudo numérico da interação biosfera-atmosfera / Amazon rainforest regrowth under nutrient stress: results from a biosphere-atmosphere interaction numerical study
This thesis investigates how the climate feedback and the nutrient feedback interact to regulate the patterns in the regrowth of the Amazon tropical forest after a large-scale deforestation. The study is performed using the fully coupled biosphere-atmosphere model CCM3-IBIS. Initially, the model was validated against observed climate and vegetation dynamics

10. Anatomical and physiological plasticity of leaves of Coffea arabica L. in response to irradiance / Plasticidade anatômica e fisiológica de folhas de Coffea arabica L. em resposta à irradiância
Morphological, physiological and biochemical parameters were examined in coffee leaves from different canopy positions. Four classes of leaves were chosen based on the mean diurnal intercepted photosynthetically active radiation. These classes (treatments) comprised leaves intercepting 30, 75, 300, 750 μmol photons m-2 s-1, hereafter referred to T1, T2,

11. Transferência do carbono de resíduos da colheita de eucalipto para frações da matéria orgânica do solo / Carbon transference from eucalypt harvest residues to soil organic matter fractions
Eucalypt plantation areas in Brazil have increased continuously over the years. The practice of removing more lignified material, such as bark and branches, from the ground after wood harvesting in eucalypt forests may prevent the stabilization of carbon (C) in recalcitrant fractions of soil organic matter (SOM). The recalcitrance of such organic fractions i

12. A redução compensada do desmatamento no Mato Grosso: uma análise econômica-ecológica / Compensated reduction in Mato Grosso state: an Ecological economic analysis
The focus of this dissertation is the system adopted by the State of Mato Grosso [Brazil] for managing and taking command and control of its environmental policies through the pillars of Ecological Economics, i.e. scale, allocation and distribution. One of the goals of SLAPR ["System for Environmental Licensing of Rural Properties", for short] is to reduce i
