13. Orchidaceae nativas da região central de São Paulo, Brasil : florística, interação com forófitos, proposta de novas espécies e propagação in vitro de uma espécie ameaçada de extinção / Native Orchidaceae of the central region of São Paulo, Brazil: floristic, interaction nested with host tree, new species proposed and in vitro propagation of threatened of extinction species
Aiming to know the sorts of Orchidaceae of the central region of the State of São Paulo, from 1996 and more intensively from 2005, visits were carried out in 125 forest fragments of 23 local municípios, with weekly periodicity and also, fortnightly. The collect were assistematics, being each fragment visited in the biggest number of points. The species not

14. Estruturas de bandas e propriedades de simetria dos modos eletromagnéticos em um cristal fotônico unidimensional
We perform in this work, through the techniques of transfer matrix, an analytical study of the photonic band structure and the density of states of a one dimensional photonic crystal consisting of a super-lattice composed by two alternating layers of air and GaAs of thicknesses a and the b, respectively. We find photonic band gaps, as expected, and also null

15. TURBULENT FLOWS OF CO2 IN A RICE CROP IRRIGATED IN RS (BRAZIL) / FLUXOS TURBULENTOS DE CO2 EM UMA ÁREA DE ARROZ IRRIGADO NO RS
This thesis quantifies the net change of CO2 (NEE) in an irrigated rice crop cultivation in RS (Brazil). The research is part of the project CT-HIDRO, which presents as main purpose the description of surface conditions for different ecosystems in the country. Data were gathered during the cultivation period, from October 2003 to March 2004. During this time

16. Fluxos de agua em especie de citro (citrus sinensis L. Osbeck - laranja pera) - Campinas - São Paulo / Water flows in species of citrus (citrus sinensis L. Osbeck - Orange pear) - Campinas - São Paulo - Brazil
The variables ecofisiológicas exercise great influence, not only in the vegetative behavior of the cultivated plants, but, above all in your acting in relation to the productive characteristics. The studies on gas exchange have been enlarging since the decade of eighty, given your importance in tropical cultivations, just as, in citrus varieties. Has been i

17. Sizing procedure of solar heating systems for agricultural products drying / Metodologia de dimensionamento de sistemas de aquecimento solar para secagem de produtos agricolas
A solar collector design procedure was proposed for sizing solar assisted crop-drying systems using empiric correlations, previously found, to determine the solar fraction supplied by the system. A case study of an in-bin crop drying was accomplished in the city of Campinas - SP with pre-heating of the air through a solar collector complemented by convention

18. Efeitos nÃo lineares em lÃquidos orgÃnicos e meios nanoestruturados
In this thesis, we report studies of nonlinear transverse effects in organic liquids, carbon disulfide (CS2) and dimetil sulfoxide (DMSO), and of fluorescent emission effects in nanostructured media, more specifically, frequency upconversion in erbium doped barium titanate nanocrystals (BaTiO3:Er3+) and laserlike emission from inverted opal nanostructure of

19. METROLOGICAL EVALUATION OF OPTICAL EMITTERS AND DETECTORS APPLIED TO THE CHARACTERIZATION OF ATMOSPHERIC PARTICULATES POLLUTANTS / AVALIAÇÃO METROLÓGICA DE EMISSORES E DETECTORES ÓPTICOS APLICADOS À CARACTERIZAÇÃO DE POLUENTES PARTICULADOS ATMOSFÉRICOS
The atmospheric pollution is a latent world-wide problem, and it is harmful to the health, visibility and climate. For these factors, several studies and researches have been developed to characterize the chemical composition of the pollutants, concentration, size of particles, etc, with the objective of constructing adjusted instruments for the control of t

20. Modelagem e analise de janelas termicas
Air flow windows or ventilated windows represent a potential concept as thermally effective windows. In the present study the thermal behavior of a ventilated window is investigated numerically. This window is composed of two glass plates forming an open channel and indoor air passing between the panes removes the solar heat. This air then exits through an o

21. InteraÃÃo entre fatores climÃticos e um recinto localizado na cidade de recife: estudo teÃrico-experimental
Ambient temperatures lying between medium and high values, combined with small thermal amplitude, high values of relative humidity and solar radiation make the city of Recife a region that can be considered as having scarce possibilities for the use of passive or low energy consumption methods for providing thermal comfort conditions in local residences. Tak

22. Estudo da atenuação da radiação solar incidente por diferentes especies arboreas
This work proposes a methodology to study reduction of solar radiation by different tree species, ITomexperimental data relating to solar radiation, air and globe temperatures, as well as relative humidity. Five species are analysed (Jatobá, Chuva-de-ouro, Magnólia, Ipê Roxo and Sibipiruna) relating to improvement of microclimate by tree hading. Incident

23. Verificação do modelo de circulação geral da atmosfera do CPTEC/COLA: ciclo hidrológico e processos de superfície / Verification of the global model circulation atmospheric of CPTEC/COLA: hydrological cycle and surface process
The verification of surface processes and hydrological cycles obtained in the climate simulation experiment using the COLACPTEC atmospheric general circulation model, forced by the monthly mean sea surface temperatures, is conducted. The simulated climate is obtained from the 12-month average of a set of four 15-month integration?s. The verification is made
