<p style="text-align: justify;"><strong>Aims</strong>: Volatile fractions were characterized for Cabernet Sauvignon wines from four different sites in Santa Catarina State, Brazil, a new grape growing region. Soil characteristics of the different sites were also assessed.</p><p style="text-align: justify;"><strong>Methods and results</strong>: A total of 49 volatile compounds were determined in these wines by gas chromatography coupled to FID, FPD detectors and to mass spectroscopy. Principal component analysis correctly classified the wines for 2004 vintage according to their origin. a-Ionone and b-ionone were present in concentrations inversely proportional in the wines; in both vintages, furaneol® and geraniol were strongly negatively correlated.</p><p style="text-align: justify;"><strong>Conclusion</strong>: Vineyard location had a strong influence on the volatile wine fraction. The varietal volatile compounds were a key factor in differentiating wines according to the sites.</p><p style="text-align: justify;"><strong>Significance and impact of study</strong>: The importance of the volatile compounds to the overall quality of wines it's already known. Santa Catarina State is a new grape growing region in Brazil that has a varied orography and its climate strongly depends on elevation. Grapes harvested from climatically different regions produce very different wine characteristics. Therefore the need for volatile profiles of Cabernet-Sauvignon wines recently produced at Santa Catarina State had significant enological and economic importance.</p>

The objective of this study was to perform the kinetics of peach drying and to adjust the experimental data obtained to empirical and diffusive mathematical models to evaluate the effect of temperature on the physical-chemical quality of the final product. The drying experiments were performed in an air circulation dryer with a velocity of 1.5 m s-1, the drying kinetics were performed at temperatures of 60, 70 and 80 &deg;C. Among the mathematical models applied, the Page model was the one that best fit the experimental data, because it presents greater efficiency in the description of the drying process. The decrease in the drying rate from the initial time to the end of the process was observed, increasing the temperature of the air caused a reduction in the drying time. It was verified through the analytical solution of the diffusion equation with infinite wall geometry that the increase of the drying temperature caused the increase of the diffusivity and convective coefficient of heat transfer. Through the Biot number, it can be stated that the first-type boundary condition would also describe the process satisfactorily. The fresh peach slices present high water content and water activity and the drying effect caused significant differences in all physical-chemical parameters analyzed.

The objective was to evaluate the production and post-harvest quality of fruit from grafted and non-grafted tomatoes. The experiment was carried out in a randomized block design with five treatments (Jiloeiro, Berinjeleira, Jurubeba, 'Intacto' rootstock and the witness the cherry tomato without grafting) and 16 replicates. In the evaluation of physical-chemical quality, the experiment followed a randomized block design in a 5x2 factorial scheme (rootstocks and storage temperatures, 10 ºC and room temperature) four replications. For a better productive contribution of the cherry tomato, the use of rootstocks from Jurubeba and Intacto is indicated, however, the use of a rootstock did not contribute to the durability and physicochemical characteristics of the fruit. When conditioned at 10 ºC, the fruits showed a better visual and physical-chemical aspect in relation to the ambient temperature, with increased durability of the product in all treatments.

Since 1998, the Ain-Karim Vineyard has been growing different grape varieties for the production of high-altitude tropical wines in the municipality of Sutamarchan, located in the Alto Ricaurte region of Boyaca (Colombia). Pruning is used to limit the number and length of branches, generating a suitable balance between plant vigor and production; thereby, regulating fruit quantity and quality and ensuring reserves for the subsequent production. This study aimed to evaluate the effect of three pruning types (short = two buds on two spurs; long = five buds on three spurs and mixed = combination of short and long pruning types) on the fruit quality of V. vinifera, Cabernet Sauvignon and Sauvignon Blanc varieties. To accomplish this, a completely randomized two-factor design was used. Physicochemical variables of fruit quality (fresh cluster weight, water content, total soluble solids (TSS), total titratable acidity (TTA), technical maturity index (TMI), and pH) were determined at harvest. The long pruning type presented the highest values for the fresh cluster weight and TSS of the fruits from both varieties and a higher TMI in the Cabernet Sauvignon variety. These results indicate that, under the conditions of the vineyard, long pruning is the most suitable.

Fish farming activities produce large amounts of waste which is disposed to environment. It contains with ammonia and nitrite as toxic substances to aquatic biota. On the other hand, it also contains nitrate as macronutrient which is useful for vegetables. Aquaponics system provides multiple benefits, namely the production of fish and organic vegetables as by-products that potentially to be a source of income. The objectives of the research were to analyse physical-chemical quality of red tilapia aquaculture and cultivated vegetable in aquaponics system, fish farm wastewater discharge for vegetable cultivation, bioconversion of aquaculture wastewater for growing vegetable biomass, and the bioeconomic of the system. The physical-chemical quality from water body of the system were as followed pH= 7.2 7.6; Temperature = 27,4 28,0ºC ; EC = 392.0 400.0 µs/cm; TDS = 180.5 189.7 ; NO3= 3.751 5.266 mg.L-1. The total biomass of green mustard in recirculating system was 92.50 kg/tray unit and in dripping system was 138 kg/tray unit. In one harvest period of red tilapia, the production of green mustard biomass was 1,152.5 kg, with an economic value of IDR 8,643,750.00 and IDR 1,680,000.00 for the red tilapia biomass.

Abstract: The study aimed to investigate the association between changes in social relations and physical activity on the quality of life of the elderly in the city of Florianópolis, Santa Catarina state, Brazil. Data on 1,197 elderly from two waves of the population and household survey, EpiFloripa Idoso, were analyzed. Multiple linear regression was performed to estimate association of social change variables and lifestyle on quality of life score (QoL; measured by CASP-16 Brazil, score can range from 0, which represents no QoL to 48, total satisfaction in all domains of CASP). The average QoL score in the sample was 37.6 (95%CI: 37.2; 38.1). The social relations that were associated with positive QoL score were to start to work, to continue to use the Internet, to start participating in religious or lifestyle groups, to remain and to become physically active, and for those who were physically active, but became inactive in the second wave. To remain living with family had a negative effect on QoL score for the elderly. Some changes in social relations had a positive effect on QoL, and results reaffirmed the importance of physical activity to healthy aging, since to pursue it in some of the waves was better than to remain inactive.
