Qualidade de pitaias de polpa branca armazenadas em diferentes temperaturas

The aim of this paper was to evaluate the effect of storage temperature on the quality of red pitaya of pulp white, produced in Itajobi city, São Paulo state. The pitayas were stored at room temperature, (21-27 degrees C with 44-63% de UR), at 18 +/- 1 degrees C, with 86-92% RH), 13 +/- 1 degrees C, with 85-90% RH and at 8 +/- 1 degrees C, with 85-95% RH. The quality was monitored during storage time through the parameters: fresh weight loss titleble acidity; soluble solids contents; vitamin C, external appearance, pH and fruit firmness. Through the results obtained may be concluded that the temperature at 8 +/- 1 degrees C it was proportioned the small fresh weight loss; the acidity, soluble solids, pH and fruit firmness were influenced by the storage temperature and storage time, but the temperature at 8 +/- 1 degrees C it was that occasioned the small change theses parameters. In general, it can be concluded that the temperature at 8 +/- 1 degrees C it was the best to maintenance the quality of pitaya fruit.

Identificação e quantificação de resinas, cargas e pigmentos em tintas látex branca

Resins, pigments and fillers constituents in white latex paint were identified and quantified after previous treatment under both low temperature and low pressure in order to get toilet powder from emulsion samples. TG/DTA allowed, under determined conditions, to distinguish the kind of resins, fillers and pigments in commercial paints. X-ray diffractometry was used to confirm the presence of pigment in the final residue from the thermal decomposition.

Avaliação de cargas difusas e simulação de autodepuração no Córrego da Água Branca, Itirapina (SP)

According to CONAMA Resolution No. 357, the Água Branca Creek is framed in Class 2 and along its course the characteristics should be consistent with this class. Evaluation of diffuse loads and simulation of auto-purification in the Água Branca Creek allowed evaluating the alterations in the quality of the freshwater. The major contribution of diffuse loads in the basin of the White Water Creek is related to agriculture. The QUAL2K modeling identified the autopurification zones at Água Branca Creek and indicated the necessity BDO removal of 75%.

Atividade inseticida e Modos de Ação de Extratos Vegetais Sobre Mosca Branca (Bemisia tabaci)

Insecticide potential and efficaciousness of vegetal extracts concentrations from six botanic families in three different modes were analyzed on the nymphs of the silverleaf whitefly Bemisia tabaci (Genn. 1889) on a tomato plantation Lycopersicon esculentum Mill. Nymph breeding was kept in cherry tomato shrubs. Test solutions were obtained from successive extractions with ethanol and evaporation in a rotary evaporator. Tests consisted of 10 solutions in four concentrations (500; 1,000; 1,500 and 3,000 μg/mL) and control treatment (distilled water + 1% DMSO) under three different modes of activity, namely, contact, translaminar and systemic. Experimental design was totally randomized with four repetitions and eleven treatments. Means were compared by Scott-Knott test at 5% probability and lethal concentrations (CL50) were calculated by POLO. In the case of contact activity mode, all extracts had efficiency above 50% with the highest concentration (3,000 μg/mL) in which the highest efficiency for all extracts tested was verified. There was a need for dose increase in translaminar activity mode for similar results, whereas in the case of systemic activity the best performance was obtained with extracts of Nerium oleander, Derris amazonica and Ipomoea carnea. Extracts of the last two caused a higher percentage when compared with that of other extracts in all activity modes lower than CL50.
