Carotenogênese em células de Haematococcus pluvialis induzidas pelos estresses luminoso e nutricional

The objective of this work was to evaluate the responses of Haematococcus pluvialis cells to the carotenogenesis induction process, under light and nutrition stress. Cells were acclimated during 15 days in WC medium, with aeration with synthetic, filtered atmospheric air and flow rate of 100 mL min-1, light intensity of 50 µmol photons m-2 s-1, photoperiod of 12 hours, and temperature of 23ºC. The following two treatments were compared: cultivation under the described conditions, but with increase of light intensity up to 350 µmol photons m-2 s-1 ; and cultivation under the same conditions as the previous treatment, but with aeration containing 4% CO2. The treatments were done in triplicate, during ten days. With the addition of CO2 and the increment in lighting, an increase was observed in the carotenoids/chlorophyll ratio and cell biomass. Cells stopped dividing on the second day of stress, when nitrate became limiting, and significantly increased their biovolume. The excretion of organic carbon and the concentration of astaxanthin increase in response to the addition of CO2. Stress by light intensity combined with CO2 addition optimizes carotenogenesis in H. pluvialis and increases astaxanthin production.

Arte e resistência: Vincent Willem Van Gogh

Esta tese apresenta uma proposta interdisciplinar para abordar o objeto artístico, almejando demonstrar como a Psicologia pode enfocar a leitura e a interpretação das produções artísticas visuais. Foram aplicados métodos psicológicos considerados eficazes para entender o fenômeno artístico e, assim, interpretar o trabalho do artista. O instrumental teórico foi o da apreensão fenomenológica e o conhecimento psicanalítoco. Trinta e nove telas de Van Gogh (produzidas em Arles, 1888; no asilo de Saint Rémy, Provence, 1889; e em Auvers Sur Oise, 1890) foram selecionadas para análise. Foram Observados os aspectos da visualidade da obra, segundo a ótica fenomenológica, e as imagens foram investigadas em sua disposição em um espaço simbólico do espaço pessoal do artista, dos elementos configurados que compõem a foma, da iluminação e cor empregadas no trabalho e da dinâmica e expressão dos conteúdos manifestos. A tese constitui-se de quatro capítulos. O primeiro apresenta a história do artista; o segundo, a teoria para abordar a percepção fenomenológica, definindo elementos utilizados para interpretar o objeto artístico; o terceiro analisa as imagens produzidas por Van Gogh no período estudado; o quarto diagnostica, analisa e interpreta a expressão das imagens. Foi também analisada a temática explorada pelo artista, de acordo com sua manifestação simbólica. A trajetória deste trabalho assemelhase ao psicodiagnóstico, que levanta hipóteses e verifica se elas são verdadeiras ou falsas. Assim foi levantada a hipótese de que a arte atuava na existência do artista como um procedimento terapêutico e mantenedor do seu equilibrio. A maior êncase da literatura recai na loucura de Van Gogh como propulsora de sua obra, visão oposta à desta tese... (Resumo completo, clicar acesso eletrônico abaixo)

Cogeração de energia com motores de combustão interna

The tertiary sector is largely responsible for the growth of electricity consumption in Brazil. The large commercial and public buildings, hypermarkets and shopping centers stand out as major consumers of electricity for lighting, power and thermal energy. Brazil presents significant potential for the deployment of small cogeneration plants, especially in the tertiary sector. Allied to this, the possibility of natural gas supply and the growing demands in favor of maintaining and preserving the environment favor the implementation of cogeneration plants. In this context, this paper presents a technical and economic analysis of installing a cogeneration plant using internal combustion engine with natural gas in a mall

Avaliação do potencial de microgeração em despacho econômico para atendimento aos requisitos de etiquetagem de edifícios

The discussions about the energy rationalization are gaining more and more space on the everyday of engineers and other professionals in the field of energy. A greater focus is being tied to commercial buildings, because they are one of the biggest responsible for the high energetic expenditure according to the National Energetic Balance, especially by the use of air conditioners for the people’s thermal comfort. Such finding made INMETRO to develop a building labeling procedure through th National Program of Electric Energy Conservation in Buildings; by means of this systematic, the built areas are classified by levels that go from A(the best) to E(the worst), taking into account envelopment, illumination system and air conditioning. A bonus process based on water rationalization, use of renewable energy sources, cogeneration systems or technical innovations, allows the classification to be changed up to one level. A study made exactly on a commercial building, the building of Foundation for Technological and Scientific Development located inside of the College of Engineering of Guaratinguetá, sought to identify technical/economic alternatives for the building certification and appealed to the bonus based on water rationalization. The present study is based on analysis of deploying a cogeneration system formed by internal combustion engine and an absorption refrigeration system as bonus alternative, so that the costs are analyzed regarding energy consumption and use of the motor. With the calculations and results, the viability of the building to receive a bonus from INMETRO through its National Program for Energy Conservation in Buildings is studied and concluded from this study whether or not you can get a better level of energy efficiency for the building in question...

Análise cinemática e dinâmica para conversão de um VW saveiro em veículo elétrico

This work aims to kinematic and dynamic analysis of a VW Saveiro in order to estimate the power requested to the engine with the imposed movement conditions. Thus, the study will be the basis to the specification of the electric engine, on the conversion of the internal combustion vehicle into electric one. First of all, a literature review was done in order to understand the state of the art for this issue and come up with the technical features of the vehicle in question. The next step is the identification and calculation of all forces acting on the prototype in motion, from 0 to 120 km/h, in intervals of 10 km/h, under the defined conditions of path and time. Then, were determined the values of the torque and rotation of the components from the transmission system, as well as the engine power, for each speed range. The results show the most influential forces on the resistence of the movement in each speed range, and the behavior of the torque curve is verified. Finally, it was also analyzed the implementation of pinwheels on the frontal area of the vehicle, in order to convert wind energy into electrical energy to supply the lighting subsystem of the vehicle and the proposal was validated. Limiting the maximum speed of the vehicle to 90 km/h, it was finally concluded that the power of the electric engine should be 40 HP

Avaliação do Efeito Fotodinâmico sobre o Crescimento in vitro de Pythium insidiosum

Photodynamic Therapy (PDT) is a therapeutic method which employs a photosensitizer and light to cause cellular death. The chemical compounds have low or none toxicity for hosts cells. Under the incidence of light, in an appropriated wavelength, these chemical compounds produce reactive oxygen which affects the biomolecules of the target-cells. The specific illumination of the affected area increases the selectivity of the therapy, since the photodynamic process occurs only in the irradiated area. Pythiosis, for instance, is a life-threatening emerging disease caused by a fungus-like organism called Pythium insidiosum. The disease occurs in man and other animals, being mostly observed in horses. Human pythiosis may present as ophthalmic, cutaneous-subcutaneous and systemic forms of lesions. Due to the fact that P. insidiosum is not a true fungus, it is refractory to most antifungal drugs and the treatment of the disease is difficult. Extensive surgery procedures, such as limb amputation, are the treatment of choice, however relapses may occur frequently. Although not totally effective, the use of immunotherapy associated to surgery have shown some results. Considering that pythiosis is an emerging disease few explored in its etiological and therapeutic aspects, which are limited and few effective, it is of great importance to encourage the development of researches for new strategies of treatment. In this sense, it was evaluated the effect of PDT on in vitro growth of the pathogen employing two chemical compounds as photosensitizer, porphyrin and chlorine, at different concentrations in combination with several energetic dosages. Porphyrin showed inhibition of growth at 25mg/mL with 100J/cm2 of energetic dosage and chlorine showed similar results employing low concentrations (0,7, 1,0 and 1,3mg/mL) with 70J/cm2 of energetic dosage...
