Preference and infestation level of Anastrepha fraterculus (Wiedemann, 1830) on fruits of some Psidium guajava L. cultivars and relation to their physicochemical parameters

This study aimed to verify the preference and infestation level of Anastrepha fraterculus (Diptera: Tephritidae) [South American fruit fly] in fruits of guava cultivars and to correlate them to variables such as peel coloration, soluble solids and pH of fruit cultivars. The following cultivars were used: Pedro Sato, Paluma, Casco and S,culo XXI. The infestation was evaluated in cages, considering two scenarios: no-choice and multiple choice. In both tests, evaluations of the fruit attraction to insects were conducted for a period of 1', 3', 5', 10', 20', 30', 1 h, 2 h, 6 h, 12 h and 24 h. The visit of A. fraterculus on the assayed cultivars in relation to the time was studied by logistic regression. After 10 days, the number of larvae in each fruit was recorded. In the multiple choice test, the visit proportions were significantly higher in the fruits of cvs. S,culo XXI and Pedro Sato than in those of cvs. Paluma and Casco. In the no-choice test, the visit proportions were significantly lower in the Paluma fruits. In both tests, the rate of fruit infestation by A. fraterculus did not differ among cvs. Pedro Sato, Paluma and Casco, whereas the fruits of cv. S,culo XXI were more infested. The indexes of pH did not interfere with the infestation of A. fraterculus, whereas a high rate of soluble solids and low color angle appear to be crucial for discriminating the fruits of the most susceptible cultivars. Infestation rate of S,culo XXI fruits displayed significant correlations with: A degrees Brix (r= 0.7078) and color angle (h) (r= -0.9499) of guava fruits under the multiple choice conditions.

Ácidos graxos da gordura de cobertura do contrafilé de bovinos Nelore e Canchim terminados em confinamento e alimentados com diferentes níveis de concentrado nas dietas

The objective was to evaluate fatty acids composition of the back fat in loin meat (Longissimus muscle) from Nellore and Canchim young bulls. The animals were finished at feedlot and received sugar cane diets with two concentrate levels (40 and 60% of dry matter). The concentrates were formulated with sunflower grains, corn, soybean meal, dry sugar cane yeast, urea and mineral mixture. The experimental design was a completely randomized design with a 2x2 factorial arrangement (genetic group x concentrate level), and the results were submitted to the variance analysis and means compared by Tukey test at 5% probability, when the interaction was significant. The loin backfat of Nellore bulls had higher concentration of conjugated linoleic acids than Canchim bulls (0.86 and 0.59%, respectively). On the other hand, the loin back fat of Canchim bulls had higher concentrations of estearic (17.07%) and linoleic acids (2.40%) and polyunsaturated fatty acids than Nellore bulls, that showed values of 13.47 and 1.44%, respectively. The Nellore and Canchim loin back fat presents significant amounts of beneficial fatty acids to human health. Levels of 40 and 60% of concentrate in the diet did not alter the fatty acids composition of loin backfat.

Taxa de desenvolvimento de força em diferentes contrações musculares

O objetivo deste estudo foi comparar a taxa de desenvolvimento de força (TDF) nas contrações isométrica e isocinéticas concêntrica a 60°.s-1 e 180°.s-1. Quatorze indivíduos do gênero masculino (idade = 23,1±2,8 anos; estatura = 174±31,3 cm e; massa corporal = 81±12 kg) participaram deste estudo. Na primeira visita foi realizada uma familiarização ao equipamento isocinético. Posteriormente, os indivíduos realizaram em ordem randômica 5 contrações isocinéticas máximas para os extensores do joelho em 60°.s-1 e 180°.s-1 para determinar o torque máximo concêntrico (TMC) e 2 contrações isométricas máximas de 3 s para determinar o torque máximo isométrico (TMI). O TMI (301,4±56,0 N.m) foi maior do que o TMC a 60°.s-1 (239,8±42,2 N.m) e 180°.s-1 (175,0±32,5 N.m). O TMC a 60°.s-1 foi maior do que o TMC a 180°.s-1. Para os intervalos de 0-30ms e 0-50ms, a TDF na condição isométrica (1196,6±464,6 e 1326,5±514,2 N.m.s-1, respectivamente) foi similar à TDF a 60°.s- 1 (1035,4±446,2 e 1134,3±448,4 N.m.s-1) e maior do que a 180°.s-1 (656,7±246,6 e 475,2±197,9 N.m.s-1), sendo ainda que a TDF na contração concêntrica rápida foi menor do que na lenta. No intervalo 0-100ms, a TDF da contração isométrica (1248,8±417,4 N.m.s-1) foi significantemente maior que a obtida na contração isocinética rápida (909,2±283,4 N.m.s- 1). A TDF obtida na contração isocinética lenta (1005,4±247,7 N.m.s-1) foi similar à obtida na contração isométrica e na concêntrica isocinética rápida. No intervalo 0-150ms, a TDF isométrica (1084,2±332,1 N.m.s-1) foi maior do que as concêntricas (60°.s-1 e 180°.s-1) (834,8±184,2 e 767,6±201,8 N.m.s-1, respectivamente), não existindo diferenças entre estas duas últimas. Conclui-se que a TDF é...(Resumo completo, clicar acesso eletrônico abaixo)

Utilização da HPLC (High Pressure Liquid Chromatography) para identificação do elemento antibacteriano extraído via hexano de Aristolochia gigantea

A ciência, principalmente a área da Farmacologia, vem ao longo dos anos desenvolvendo medicamentos eficazes e seguros para o tratamento médico de infecções bacterianas e seu sucesso reduz cada vez mais as mortalidades causadas por estes e outros microrganismos. Logo, a busca por novos compostos moleculares para o uso terapêutico é de grande importância para ampliar a gama de substâncias eficientes, buscando-se também menos efeitos colaterais, que podem ser disponibilizadas no mercado. Visando encontrar estes novos componentes, recorre-se às informações presentes em diversas áreas, principalmente na Etnobotânica, ciência que explora, verifica e armazena o conhecimento popular adquirido pelo homem através da sua interação com as plantas, sobre suas propriedades benéficas ou não, e usos mais comuns.

Letramento e Oralidade: Notas sobre Pontuação em um Bate-papo Virtual Infantil

Based on a heterogeneous concept of writing, this paper aims at analyzing ‘breaks’ in utterances of a virtual chat for writers between 8 and 12 years of age. The hypothesis is that the segmentation of an utterance in different lines in a short period of time characterizes the writing on the internet as nonconventional and relates it to the prosody and rhythm of the language not restricted to the phonic or graphic dimension of the verbal language.

It is also obtained an extended version of the Laplace-like equations for quaternions, now written in terms of both electric and gravitational fields.

Optical filters and resonant cavities based on di-ureasil organic–inorganic hybrids

Sol–gel derived poly(oxyethylene)/siloxane organic–inorganic di-ureasil hybrids containing different amounts (20–60% mol) of methacrylic acid (McOH) modified zirconium oxo-clusters (Zr-OMc) were processed as thin films and transparent and shape controlled monoliths. Laser direct writing was used to create channel waveguides, Bragg gratings, Fabry–Perot cavities and optical filters. The resulting Fabry–Perot optical cavity displays a free spectral range of 16.55 GHz and a fringe intensity contrast of 5.35 dB. Optical rejection values between 6.7 and 10.4 dB were obtained by varying the amount of the Zr-OMc oxo-clusters.

A gestão democrática da educação: expectativas da escola sobre a participação da família

The objective of this study was to verify the importance of family involvement as an element of democratic school management challenging legislation, intellectual discourse and the perspective of school staff. For this purpose, we analyzed the information obtained by means of instrument PDESchool applied in the public schools of a medium-sized city in the state of São Paulo. We found that the school teams identify school / family interaction as an important factor in the work to be developed, although families show little involvement in the management of school units.

Estudo comparativo da inclinação do plano oclusal de modelos para cirurgia ortognática montados em dois tipos de articuladores semi-ajustáveis

Purpose: The aim of this study was to compare occlusal plane angulation measured in two different types of semi-adjustable articulators with that obtained on the lateral cephalometric radiograph. Materials and Methods: 20 patients due to undergo orthognathic surgery had dental casts mounted in two different types of semi-adjustable articulators through face bow transfer from the position of the maxilla and occlusal recording to the mandible. After mounting, the inclination of the occlusal plane in the articulators was measured and compared with the inclination measured at on both articulators and compared with the inclination measured on the lateral cephalometric radiographs and between the articulators themselves. The results obtained werestatistically analyzed. Results: Mean angulation values for the Bio Art (7.55º) and Kavo (-5.70º) articulators differ by 13.25º, which is statistically significant (p=0.00). When individually compared to the lateral cephalometric radiograph (5.075º), the Bio Art articulator showed more similar angulation values, with a difference of 2.475º, while the Kavo articulator presented a difference of 10.775º. Conclusion: Neither of the models of semi-adjustable articulators accurately reproduced the inclination of the maxillary occlusal plane of patients with dentofacial deformities; the difference between the two articulators tested and the lateral cephalometric radiograph was lower for the Bio Art than for the Kavo articulator.
