This work aimed to study aspects related to vegetative and productive development of plants and characteristics and chemical components of bunches of six seedless grape varieties at environmental conditions of São Francisco river's valley, Northeastern Brazil. The experiment was carried out during 1997 and 1998. The varieties tested were grafted on IAC 572 ('Jales') rootstock. The experimental model utilized was totally randomized, and with parcels subdivided into different production cycles. The results showed significative differences among varieties at different pruning times. The average weight of bunches varied from 164.8 g for 'Marroo Seedless' and 203.5 g for 'Beauty Seedless'. The average diameter of berries was superior to 15.7 mm for all of the varieties. The total soluble solids varied from 14.05°Brix in 'Canner' to 19.6°Brix in 'Venus'. The total titratable acidity (ATT) was lower than 0.91 g tartaric acid/100 mL of juice. The ratio SST/ATT varied from 19.05 in 'Beauty Seedless' to 28.57 in 'Vênus'. 'Vênus' and 'Marroo Seedless' were the most productive varieties, with the average annual production of 24 ton/ha and 20 ton/ha, respectively.

Cultivars with high yield, adaptability and desirable technological characteristics are a must. The objective of this work was to evaluate agronomic and technologic characters of common bean genotypes from carioca commercial group. Genotypes were cultivated in water growing season, in 2001 and 2002. The experimental design was by randomized blocks with 29 genotypes and four replications. The IAC-Carioca, FT-Bonito, Rudá, Porto Real, CNFC 8008, CNFC 8011, CNFC 8012, CNFC 8013 and CNFC 8156 genotypes yielded above the average. The genotypes IAC-Carioca, CNFC 8012 and CNFC 8156 presented the best results with 3,000 kg ha-1 and 20 minutes cooking time.

The use of laboratory animals in conjunction with research on the human organism provides a basis for on understanding of several important physiological and pathological processes. Besides, the results of experimental studies enable technical and safety improvements to be made in surgical techniques used in the medical clinic. As living biological material is involved, we should guarantee its physical well-being, taking into account microbiological contamination and the genetics, nutrition and correct manipulation of the animals, in order to avoid incorrect conclusions from the experiments or unnecessarily large numbers of animals being used. In parallel with the concerns and legislation on the use of laboratory animals, there is also a growing preoccupation with the welfare and safety of those who handle the laboratory animals, since they run the risk of acquiring occupational diseases through contact with zoonotic pathogens or developing allergies. Prevention requires the application of modern technological advances in the design of the animal house and in the work routines. Unfortunately, few establishments in Brazil possess staff with adequate training and a basic infrastructure of research that includes the laboratory animal breeding centers, equivalent to those existing ones in the United States and Europe.
