Estudo da fotoisomerização em filmes de polímero triacrilato dopado com azocorante disperse red 1

Triacrylate resins are widely used to fabricate 3D microstructures, photonic crystals and optical devices. These resins can be doped with photosensitive materials like Disperse Red 1 (DR1), an Azo dye that changes its molecular configuration from trans to cis (photoisomerisation) with variations in their optical absorption spectrum when irradiated with ultraviolet or visible light. The reversibility of this process is thermally activated and occurs when the molecule remains at dark. In this work was prepared a 1:1 mixture of ethoxylated-6-trimethylolpropane (SR499) and tris-2-hydroxyethyl-isocyanurate (SR368) triacrylate resins, plus photoinitiator Lucirin TPOL, forming a UV curable polymeric matrix doped with DR1. Thin films were deposited onto glass slides by spin-coating technique. The films showed photochromic effect when illuminated with a low power diode laser (450 nm and 50mW/cm2). This effect is reversible after sample is left in dark. Thermochromic effect was evaluated by optical absorption measurements in the range of 40 to 140oC, heating the samples in-situ

Caracterização da contribuição da albumina para a formação do espectro de ressonância magnética nuclear (RMN) do plasma sanguíneo

The plasma represents a average of the information referring biochemists to the physiology of the organism as a whole, therefore it indirectly or directly interacts with all tissues of the body. In such a way the plasma can be considered as a metabolic “soup”. Using the Nuclear Magnetic Resonance Spectroscopy sanguineous plasma spectra had been generated and using deconvolution techniques it was possible to know the contribution of the albumin for the formation of the spectra of the sanguineous plasma

Espectro de gotas gerado por diferentes adjuvantes e pontas de pulverização

The application technology shows many parameters related to the quality of the application, one is the droplet spectrum, which is influenced by the spray nozzles and the adjuvant used. Therefore, the objective of this work was estimate the behavior of the droplet spectrum generated with different nozzles and different adjuvants. The experiment was installed containing four solutions from different type adjuvant dilution, as vegetal oil, mineral oil, surfactant and drift reduction, which were applied with two nozzle, one pre-orifice flat fan (DG 8003 VS) and other of air induction flat fan (AI 8003 VS), totaling 8 treatments with 3 repetitions. The experiment was realized in ideal weather conditions for spraying. The treatments averages were compared using Confidence Interval at 95% probability and the correlations between variables were analyzed using Pearson at 5% of probability. The analysis of droplet spectrum showed different behavior for each adjuvant and nozzle. The surfactant treatment showed VMD superior for all treatments when sprayed with AI nozzles. For the %vol.<100 µm the lowest value found was for the AI nozzle in combination with the surfactant. The significant correlations found for the nozzles AI and DG were negative between VMD and %vol.<100 µm. It can be concluded that the values of DMV and %vol.<100 µm showed that the nozzle with pre-orifice have droplet spectrum more prone to drift. The surfactant showed to be the best drift reduction technique when combined with the AI nozzle.

Influência de adjuvantes no espectro de gotas de ponta com indução de ar

This study aimed to verify the influence of adjuvants on the droplet spectrum of an air induction nozzle. The experiment used nine spray solutions, one including only water and eight containing adjuvants: Nimbus® (mineral oil), Óleo vegetal Nortox (vegetal oil), Li-700® (a mixture of lecithin and propionic acid), Agral® (nonyl phenoxy poly ethanol), In-Tec® (nonyl phenol ethoxylate), Antideriva (nonyl phenol ethoxylate), Silwet® L-77 Ag (copolymer polyester and silicon) and TA 35 (sodium lauryl ether sulfate). A flat fan air induction nozzle Hypro® Guardian Air 110 03 was used for the droplet spectrum evaluation. The study was conducted at the Laboratory for Particle Size Analysis (Lapar), at FCAV/UNESP, Jaboticabal/SP - Brazil. The determination of the droplet spectrum characteristics (Volume Median Diameter/VMD, percentage of droplets smaller than 100 micrometers and span) was carried out by a particle size analyzer by laser diffraction Mastersizer S (Malvern Instruments). For statistical analysis the mean values were compared using Confidence Interval at 95% (CI 95%). The results showed that for the Hypro® GA air induction nozzle the oil based adjuvants (Óleo Vegetal Nortox e Nimbus®) increased the VMD. The percentage of droplets smaller than 100 micrometers was lower for the Agral®, Antideriva, In-Tec® e TA 35, in comparison with the Óleo Vegetal Nortox and Li-700®. The span was higher for the oil based adjuvants (Óleo Vegetal Nortox e Nimbus®) and lower for the TA 35 (sodium lauryl ether sulfate), showing that the TA 35 adjuvant has a potential to improve the quality of the droplet spectrum of the Hypro® GA 11003 nozzle.

Produção semissólida de metarhizium anisopliae e beauveria bassiana em diferentes substratos e efeito da radiação ultravioleta e da temperatura sobre propágulos desses entomopatógenos

The present study was aimed to evaluate different (semi-solid) media for the production of Metarhizium anisopliae and Beauveria bassiana propagules, and to evaluate the tolerance of these propagules to ultraviolet radiation and temperature. The experiments were performed at the Biological Control Laboratory of the Instituto Biológico at Campinas, São Paulo, Brazil. For both fungi, 6 repetitions were performed for each of the 17 treatments: corn starch, full rice, parboiled rice, type-1 rice, type-2 rice, oat flakes, canjiquinha [grits], wheat flour, raw cassava flour, yellow corn flour, special wheat flour, corn flour, corn in grains, cassava starch, soy in grains, crushed wheat, and turf. The viability analysis was done in plastic plates containing BDA. For the bioassays involving exposure to ultraviolet light and temperature, BDA was also used for viability analysis, and each treatment was exposed to the UV radiation for 0, 25 and 50 seconds, the temperature exposure being at 20, 25, 30 and 35º C. Using a Potter tower, 2 mL of fungus suspension from each treatment was inoculated to the Diatraea saccharalis caterpillars. Regarding the sporulation, the largest concentrations of M. anisopliae and B. bassiana were found for the treatments with parboiled rice, type-1 rice, type-2 rice, yellow corn flour, corn flour and crushed wheat. The viability of all treatments was superior to 94.00%. Also, the longer the duration of the exposition to the UV, the smaller the number of fertile conidia. At 35o C, a significant loss of conidia viability was observed, and all the treatments presented some level of virulence.
