Desempenho da aplicação foliar de zinco em feijoeiro

The nutritional requirements of crops, in general, becomes more intense with the beginning of the reproductive phase, being more critical at the time of seed formation, when considerable amounts of nutrients are they translocation, this requirement should be increased to the fact that nutrients are essential to training and development of new bodies of booking. This study aimed to evaluate the agronomic efficiency of foliar application of zinc (zinc oxide Zn 700 g L-1 ) in bean plant, compared to leaf application of zinc sulphate (ZnSO4) and control (without application of Zn). The experiment was installed in the Faculty of Agricultural Sciences - UNESP / Campus de Botucatu-SP. Was placed in containers with a capacity of 20L of soil and leaf applications encompassing four schemes and two of rain, with 5 replicates per treatment, a total of 40 vessels. The results for the factorial design did not show in general, significantly different answers when evaluated on the simulation of rain or the lack of simulation. The treatment (700g L-1 of ZnO) has demonstrated agronomic efficiency as its foliar application, with results equal or exceed the application of ZnSO4 and control when applied at the same dose of Zn.

Potencial gravitacional lunar

We know that the orbit of a lunar satellite, and consequently its orbital lifetime is mainly inuenced by the gravitational field of the Moon, Earth and Sun. In this text we study the Lunar gravitational potential and its influence on the gravitational field. We adapted a program in order to map the Moon gravitational field. To that end it was necessary to develop a program that allows the simulation and mapping the lunar full potential. Our program was based on the program developed by Hélio Kuga, and adapted to our case (Moon). We used the model proposed by Konopliv et al. 2001, we proposed various degree and order expansions of spherical harmonics that served us to compare and validate our program

Dispositivo de microdescargas em gases na pressão atmosférica

This work describes the development of an electro-mechanical micro-discharges device operating at ambient condition of pressure and temperature, capable to produce plasma jets for surface finishing. The discharges are produced through a needle shape electrode hollow cathode type by which flows the helium gas. The voltage applied on the electrode is provided for an AC/AC switching voltage converter of full-bridge topology. The converter is energized by a power line of 110/220 VAC, 60 Hz and gives a 1000 V peak-to-peak from 5 kHz to 40 kHz square waveform output. The output frequency is defined by a control signal provided by an external signal generator. The equipment setup includes output acquisition of voltage and current and a photo-detector for photo-electrical measurements, which allows an optical characterization of the plasma jet

Instituições, confinamento e relações de poder: questões metodológicas no pensamento de Michel Foucault

O artigo trata de uma discussão sobre a análise de instituições a partir do pensamento de Michel Foucault. Um dos objetivos é interrogar a afirmação de que Foucault definiu os mecanismos disciplinares como restritos ao confinamento em algumas instituições. Visa-se ressaltar que as relações de poder não eram propriedade de uma instituição ou apenas restritas ao Estado. Busca-se pensar como as tecnologias biopolíticas também extrapolam o âmbito estatal e operam governos das condutas por meio de articulações e composições e não ficam apenas fixadas em uma entidade de maneira naturalizada. Outro ponto tratado é o questionamento realizado por Foucault da visão de poder apenas como repressão e massificação operada pelas instituições. Finaliza-se, apontando a preocupação central de Foucault, qual seja, a análise das práticas, e não apenas das instituições.

A genealogia em Foucault: uma trajetória

Este artigo tem o objetivo de realizar uma trajetória da genealogia enquanto modo de escrever a história como pergunta/problema, de acordo com Michel Foucault, rompendo com uma história contínua, linear, teleológica, que buscava origens e semelhanças entre os objetos e as tentativas de estabelecer relações causais entre os acontecimentos. Uma história das práticas discursivas, de poder e subjetivação era a empreitada proposta por Foucault. A análise da proveniência e da emergência rompia com toda uma tradição historiográfica que fazia dos eventos memória e monumentos construídos e interpretados por categorias de semelhança. Foucault questiona este modelo de fazer história, trabalhando com novos temas e problemas e operando com a multiplicidade de acontecimentos dispersos, raros, heterogêneos, em recortes de séries de enunciados em arquivos, sem busca de origens primeiras e sem fins utilitaristas a alcançar.

Aberrant transcript produced by a splice donor site deletion in the TECTA gene is associated with autosomal dominant deafness in a Brazilian family

We ascertained a Brazilian family with nine individuals affected by autosomal dominant nonsyndromic sensorineural hearing loss. The bilateral hearing loss affected mainly mid-high frequencies, was apparently stable with an early onset. Microsatellites close to the DFNA8/DFNA12 locus, which harbors the TECTA gene, showed significant multipoint lod scores (32) close to marker D11S4107. Sequencing of the exons and exon-intron boundaries of the TECTA gene in one affected subject revealed the deletion c.5383 + 5delGTGA in the 5' end of intron 16, that includes the last two bases of the donor splice site consensus sequence. This mutation segregates with deafness within the family. To date, 33 different TECTA mutations associated with autossomal dominant hearing loss have been described. Among them is the mutation reported herein, first described by Hildebrand et al. (2011) in a UK family. The audioprofiles from the UK and Brazilian families were similar. In order to investigate the transcripts produced by the mutated allele, we performed cDNA analysis of a lymphoblastoid cell line from an affected heterozygote with the c.5383 + 5delGTGA and a noncarrier from the same family. The analysis allowed us to identify an aberrant transcript with skipping of exon 16, without affecting the reading frame. One of the dominant TECTA mutations already described, a synonymous substitution in exon 16 (c.5331 G<A), was also shown to affect splicing resulting in an aberrant transcript lacking exon 16. Despite the difference in the DNA level, both the synonymous substitution in exon 16 (c.5331 G<A) and the mutation described herein affect splicing of exon 16, leading to its skipping. At the protein level they would have the same effect, an in-frame deletion of 37 amino-acids (p.S1758Y/G1759_N1795del) probably leading to an impaired function of the ZP domain. Thus, like the TECTA missense mutations associated with dominant hearing loss, the c5383 + 5delGTGA mutation does not have an inactivating effect on the protein. (C) 2012 Elsevier B.V.

Are patients with encephalocraniocutaneous lipomatosis at increased risk of developing low-grade gliomas?

Cancer-prone genetic disorders are responsible for brain tumors in a considerable proportion of children. Additionally, rare genetic syndromes associated to cancer development may potentially disclose genetic mechanisms related to oncogenesis. We describe two pediatric patients with encephalocraniocutaneous lipomatosis (ECCL), a very rare genetic syndrome with around 60 reported cases, which developed low-grade astrocytoma at 3 and 12 years of age. Patients with ECCL seem to be at risk of benign forms of osseous tumors such as ossifying fibromas, odontomas, and osteomas. The association between brain tumor and ECCL was previously reported only once, in a pediatric case of a mixed neuronal-glial histology. Whether ECCL may be a genetic condition of predisposing brain tumor in children strongly needs to be addressed.
