1. Chilling and forcing requirement of five international fig cultivars grown in Southeastern Brazil
ABSTRACT Chill hours availability influence break dormancy, sprouting and production of temperate fruits trees in different regions. However, there are few reports on the subject for fig tree. This study aimed to evaluate the effects of the accumulated chilling hours on the physiology and dormancy release of fig cultivars. Stem cuttings of five fig cultivars

2. HYBRID SYSTEM SIMULATION TO SUPPLY HEATED AIR TO A SOLAR FOOD DRYER
ABSTRACT The intermittence of solar radiation, due to continuous rainy or cloudy days, is a limitation of simple and small solar dryers. These conditions often make them impossible to use. By including storage systems (thermal accumulation) and/or auxiliary energy sources, drying processes or dehydration can be conducted continuously, even during periods of

3. Evaluation of the contributions of possible sources to the leucosome of the diatexite of Socorro-Guaxupé Nappe, in the Alfenas Region, MG, Brazil
Abstract The Socorro-Guaxupé Nappe crops out in southern Minas Gerais and it has an intermediate unit called Metaxite Unit, dominated by diatexites at its base, with large volumes of leucosome and schollen of stromatic garnet-biotite metatexite. Leucosome within the schollen crystallized via fractional crystallization and is dominated by plagioclase and qua

4. Development and evaluation of an inhalation chamber for in vivo tests
ABSTRACT The bioavailability, toxicity, and therapeutic efficacy of a drug is directly related to its administration route. The pulmonary route can be accessed by inhalation after fumigation, vaporization or nebulization. Thus, pharmacological and toxicological evaluation accessed by an apparatus specifically designed and validated for this type of administr

5. DECOMPOSIÇÃO DE RESÍDUOS CULTURAIS DE PLANTAS DE COBERTURA DE SOLO E EMISSÕES DE ÓXIDO NITROSO / COVER CROPS RESIDUES DECOMPOSITION AND NITROUS OXIDE EMISSIONS
The inclusion of summer cover crops (SCC) in the no-till system is an interesting alternative to promote the addition of elevated quantities of plant biomass and nitrogen (N) to the soil. The C and N dynamics during the SCC residue decomposition can control the nitrous oxide (N2O) fluxes to the atmosphere. This study was carried out to quantify the SCC resid

6. Estudo da exalação de radônio em placas e tijolos de fosfogesso de diferentes procedências / Study of radon exhalation from phosphogypsum plates and blocks from different origins
O fosfogesso é um resíduo da indústria de fertilizantes fosfatados que concentra radionuclídeos naturais. Neste trabalho foi estudada a taxa de exalação de 222Rn em placas e tijolos de fosfogesso, visando sua utilização na construção de residências. Para tanto, foram determinadas a taxa de exalação de 222Rn por meio da técnica da câmara de acu

7. Avaliação do desempenho energetico e operação de uma camara de estocagem com fluido secundario termoacumulado / Energy performance evaluation and operation of a cold storage chamber with thermo-accumulated secondary fluid
El uso racional de la energía es, en la actualidad, una preocupación mundial. Las cuestiones ambientales relativas a la degradación de la capa de ozono y el calentamiento global van conjuntamente al buen uso energético. La refrigeración se destaca como grande consumidora de energía eléctrica, debido principalmente al uso de los compresores. Hacer un e

8. Influence of ethylbenzene on the pharmacokinetic enantiosselective of lercanidipine in rats. / Influência do etilbenzeno na farmacocinética enantiosseletiva do lercanidipino em ratos
Cytochrome P450 (CYP) is responsible for biotransformation of drugs, pollutants and other xenobiotics. Lercanidipine (LER), clinically employed as quiral compound in the treatment of arterial hypertension, is biotransformed by CYP3A4. Etylbenzene (EBZ), a solvent of large industrial use, is substrate and inducer of CYP3A in rats. The present study investigat

9. Cryopreservation of the sugarcane germplasm / Criopreservação de germoplasma de cana-de-açúcar
This study was carried out to develop some protocols for cryopreservation of sugarcane germplasm in liquid nitrogen at -196C. The exposure time of the shoot tips encapsulated in the laminar flow chamber for obtaining the moisture contents of 30, 20 and 10% was determined in an assay. The results were analyzed and interpreted, by using the free R software. Th

11. Efeitos fisiológicos e bioquímicos causados pela deposição de ferro particulado em Clusia hilariana, uma espécie de restinga / Physiological and biochemical effects of iron ore dust in Clusia hilariana, a plant of restinga
Clusia hilariana, a CAM plant with crucial ecological role, has a broad distribution in brazilian restingas. With the aim to evaluate the physiological and biochemical effects of iron ore particulate matter (MSPFe), deposited in different fashions, on this species, three distinct experiments were carried out. Young plants were hydroponic cultivated in Hoagla

12. Aspects of seeds germination and influence of light on the development, leaf anatomy and chemical composition of essential oil in Ocimum gratissimum L. / Aspectos da germinaÃÃo das sementes e influÃncia da luz no desenvolvimento, anatomia foliar e composiÃÃo quÃmica do Ãleo essencial em Ocimum gratissimum L.
Before the need to deepen the knowledge about medicinal flora, the species Ocimum gratissimum L., an important producer of essential oil much utilized as a phytotherapeutic, was selected. The main objectives in this work were to evaluate physiologic aspects of germination and storage of seeds as well as to investigate growth leaf anatomy and accumulation of
