Otimização da aplicação de Fluazifop-P-Butil em pós-emergência na cultura de soja (Glycine max)

The objective of this study was to evaluate the possibility of reducing spray concentration and volume of Fluazifop-p-butyl applications on postemergence soybeans, while maintaining weed control and growth selectivity. The study was conducted in the experimental area of the Teaching and Research Farm of FCAV/Unesp - Jaboticabal Campus, during the agricultural season of 1998/99, carried out on a crop of soybean cultivar FT 2009. The experimental setup utilized was a randomized block design with 24 treatments, 20 following a factorial scheme 2 x 2 x 5 and 4 control treatments. The factors examined were: spray volume (100 and 200 L ha-1); reduced spray concentration - 75.2 and 112.8 g of fluazifop-p-butyl/ha (40 and 60% of the recommended concentration, respectively); and application schedule (5 A.M., 9 A.M., 1 P.M., 5 P.M. and 9 P.M.). The controls were applications at the recommended concentration (188.0 g fluazifop-p-butyl/ha), using volumes of 100 and 200 L ha-1, and treatments without weed control and weeds controlled with manual hoeing. The main species of weeds that emerged in the experimental area were: Cenchrus echinatus, comprising 60% of the infested sections; Digitaria horizontalis, 10%, and Eleusine indica, 30%. All fluazifop-p-butyl applications made up to 9 A.M. and from 5 P.M. effectively controlled the three species of weeds and provided a selective growth of soybeans. Therefore, the use of fluazifop-p-butyl can be optimized by reducing both the concentration and the volume of the spray for applications times providing favorable conditions for crop dusting.

Biological aspects of Aphis gossypii Glöver, 1877 (Hemiptera: Aphididae) on colored lint cotton cultivars

This paper outlines the results of a study into the biological aspects of Aphis gossypii Glöver on colored cotton cultivars through the construction of life tables. In addition, we evaluate the influence of density of gossypol glands and trichomes of leaves on the biology of the aphid. Tests were conducted in a climate chamber at 25 ± 2°C, with relative humidity (RH) at 70 ± 10%, and a photophase of 12 hours, using the cultivars BRS Rubi, BRS Safira, and BRS Verde. Newly hatched nymphs were individually isolated in petri dishes containing leaf discs of cotton cultivars on a layer of water-agar (1%) of approximately 5 mm thick. An evaluation of the trichomes and gossypol gland densities of the cotton leaf plants was performed under a stereomicroscope, delimited to an area of 1 cm², and a count and identification of those on the surface was made. The feed substrates that were evaluated influenced the nymphal stage of A. gossypii. BRS Verde provided the shortest duration and BRS Safira was the longest during this phase. The cultivar BRS Verde, with the lowest density of trichomes, provided a large number of nymphs and led to a higher net reproductive rate (R0). Given these results, conclusions can be drawn that the colored cotton cultivars influence the duration of nymphal and adult stages of A. gossypii. The cultivar with a high density of trichomes on leaves (BRS Safira) adversely affects the fertility parameters of A. gossypii.

Revisão crítica das canções para a voz e piano de Heitor Villa-Lobos: publicadas pela Editora Max Eschig

Esta revisão crítica apresenta uma análise do conjunto de canções de Heitor Villa-Lobos (1887-1959), publicado pela editora Max Eschig de Paris. As trinta canções publicadas formam um painel importante do estilo vocal e pianístico do compositor, pontuando praticamente toda sua vida criativa. O trabalho respeitou a ordem cronológica da criação das coleções de canções: de 1919 e 1946. Além das trinta canções publicadas, incluiu-se no trabalho as três canções não publicadas que fazem parte da série Canções Típicas Brasileiras. Tais obras estão depositadas nos arquivos do Museu Villa-Lobos no Rio de Janeiro, Brasil.

Chemical composition and lipoxygenase activity in soybeans (Glycine max L. Merr.) submitted to gamma irradiation

Soybeans are an important food due to their functional and nutritional characteristics. However, consumption by western populations is limited by the astringent taste of soybeans and their derivatives which results from the action of lipoxygenase, an enzyme activated during product processing. The aim of this study was to evaluate the effect of gamma irradiation on the chemical composition and specific activity of lipoxygenase in different soybean cultivars. Soybeans were stored in plastic bags and irradiated with doses of 2.5, 5 and 10 kGy. The chemical composition (moisture, protein, lipids, ashes, crude fiber, and carbohydrates) and lipoxygenase specific activity were determined for each sample. Gamma irradiation induced a small increase of protein and lipid content in some soybean cultivars, which did not exceed the highest content of 5% and 26%, respectively, when compared to control. Lipoxygenase specific activity decreased in the three cultivars with increasing gamma irradiation dose. In conclusion, the gamma irradiation doses used are suitable to inactivate part of lipoxygenase while not causing expressive changes in the chemical composition of the cultivars studied.

Desenvolvimento e estabilidade de formulações semi-solidas contendo extratos de soja (Glycine max (L) Merr.)

Alguns vegetais, como a soja (Glycine max L. Merr), despertam interesse, pois fornecem, entre outras substâncias, as isoflavonas, que apresentam importantes propriedades estrogênicas e, também, atuam como antioxidantes, antifúngicos e anticancerígenos. A menopausa, causada pela deficiência hormonal, é acompanhada de vários transtornos metabólicos, como perda de massa óssea, fenômenos vasomotores, dislipidemia, resistência insulínica, ganho de peso, depressão e aceleração do envelhecimento cutâneo. A terapia de reposição hormonal (TRH) é eficaz, embora possa causar efeitos secundários, como câncer de mama. Nestes casos, a fitoterapia com fitormônios por via cutânea é uma alternativa importante. Dentre as preparações de uso tópico, sistemas emulsionados e géis são muito utilizados, pois favorecem a solubilidade e a estabilidade de fármacos. Para avaliar a estabilidade das formulações, foram consideradas as características organolépticas (aspecto, cor, odor) e as características físico-químicas (valor de pH, viscosidade e densidade, etc.), separação de fases e/ou coalescência. Algumas formulações apresentam-se com características desejáveis e adequadas para a veiculação de isoflavonas presentes em extrato de soja, podendo-se sugeri-las como sistemas adequados e estáveis para sua veiculação pela via dérmica

Deslizar nas ruas, entre Mário de Andrade e Max Jacob

This essay intends to point to a possible dialogue between Mário de Andrade and Max Jacob, starting from the books of poems Paulicéia desvairada (1922) and O losango cáqui (1926), Le cornet à dés (1916) and Le laboratoire central (1921). Divided into three parts, it investigates the figuration in the two poets of the harlequin’s image, through which both would operate several displacements. One of them, the resumption of a romantic mythology of the artist, as in Baudelaire, and the conscience of his staging character. Other, through the opposition between reason and madness, legitimating a lyrical state as a way to a different perception of the reality. Lastly, through the proposition of an artistic sincerity, moral of work with deep impact over the literary language.

Questões morais do Le Cabinet noir de Max Jacob

This essay aims at presenting the book Le Cabinet noir of Max Jacob, a book of fictional letters with comments, taking into consideration the moral judgment: right conduct, principles that govern modes of action. This strategy demonstrates the ambiguity of Max Jacob’s project: divided into a certain Catholicism, which he practiced, and avant-garde literature. On the other hand, this study points to the various contradictions such as a certain morality towards the family preservation or friendship, virtues or Christian attitudes and bourgeois conveniences. Finally, it establishes the dimension of desire in face of René Girard’s questionings in the essay Mensonge romantique et vérité romanesque.
