13. TEMPORARY AND SPACE VARIATION OF THE MORPHOLOGIC PARAMETERS IN SEEDLINGS OF PINUS AND EUCALYPTUS / VARIAÇÃO ESPACIAL E TEMPORAL DOS PARÂMETROS MORFOLÓGICOS EM MUDAS DE PINUS E EUCALIPTO
Even whith the advanced of production of seedlings, many problems still exist and they must be solved, mainly in what refers to the expedition of seedlings of the vegetation house. So, this study has as aim to establishes periods and ways of expedition of seedlings of Pinus elliottii Engelm and Eucalyptus grandis W. Hill ex Maid, with uniformity of their mor

15. ESTUDO DOS ASPECTOS REPRODUTIVOS EM Luehea divaricata Martius (AÇOITA-CAVALO) / STUDIES OF REPRODUCTION ASPECTS IN AÇOITA-CAVALO (Luehea divaricata Martius)
The Luehea divaricata Martius (açoita-cavalo) is a tree of Tiliaceae family that is of the interest of industries due to wood the quality and also reflorestation programs. Studies about propagation are justified mainly when working with native plants, that have few research results. Two studies were conducted about specie propagation: one vegetative way and

16. Resfriamento a vacuo de alfaces hidroponicas (Lactuca sativa L.) cv. Salad bowl : avaliação do processo e da vida pos-colheita. / Vacuum cooling of the alfaces hydroponics lettuces (Lactuca sativa L.) cv. Salad bowl: process evaluation and of the life postharvest time.
The principle of vacuum cooling process is based on the evaporation of water. The water evaporation occurs under low pressure and the boiling point temperature of water is lowered. Refrigeration systems are used for the condensation of the water vapor. For the condensation of water vapor, the adsorption appears as a good technological alternative. The vacuum

18. Dinâmica de populações de cianobactérias em reservatório eutrofizado no semi-árido nordestino brasileiro.
The Armando Ribeiro Gonçalves reservoir, located in the semi-arid of the Rio Grande do Norte (06o08 S ; 37o 07 W), in Northeast Brazil, represents 68% of the total surface water accumulated in the state. The reservoir, with maximum volumetric capacity of 2.4 x 109, provides 400 thousands habitants and also is destined to irrigation, leisure and fishing. It

19. Otimização da tecnica de densitometria optica em imagens radiograficas de peças osseas : estudo "in vitro"
This experiment was designed in order to determine the sensibility and precision of radiographic optical densitometry by the characteristic curves setorization of radiographics films. We used the mathematic expression describted by PELÁ et aI. (1990), a special computer software (PELÁ et aI., 1992) adapted for to this analysis and the correction of X radia

21. A Genetic Discontinuity in a Continuously Distributed Species: Mitochondrial DNA in the American Oyster, Crassostrea Virginica
Restriction site variation in mitochondrial DNA (mtDNA) of the American oyster (Crassostrea virginica) was surveyed in continuously distributed populations sampled from the Gulf of St. Lawrence, Canada, to Brownsville, Texas. mtDNA clonal diversity was high, with 82 different haplotypes revealed among 212 oysters with 13 endonucleases. The mtDNA clones group

22. Preparation and in vitro evaluation of polystyrene-coated diltiazem-resin complex by oil-in-water emulsion solvent evaporation method
The purpose of this study was to examine the suitability of polystyrene-coated (PS-coated) microcapsules of drug-resin complex for achieving prolonged release of diltiazem-HCl, a highly water-soluble drug, in simulated gastric and intestinal fluid. The drug was bound to Indion 254, a cation-exchange resin, and the resulting resinate was microencapsulated wit
