Extração e exportação de nutrientes pelo feijoeiro adubado com nitrogênio, em diferentes tempos de implantação do sistema plantio direto

Common bean grown in no-tillage (NT) systems has increased markedly in Brazil. Thus, to optimize the fertilizer recommendations, it is important to know the nutritional requirements of this crop when grown under new and established NT systems, which can change the nutrient availability and crop response to nitrogen (N) fertilization. The objective was to evaluate the extraction and exportation of nutrients by common bean as function of N fertilization on soil under new and established NT systems. The experiment was carried out in two agricultural years, on a Red Nitosol (Alfisol) in Botucatu, São Paulo State, Brazil. A randomized complete block design was used in a split-plot scheme with four replications. The plots consisted of areas under NT systems after different periods of adoption and the subplots of four forms of N application to common bean (T0: control, without nitrogen; T1: 60 kg ha-1 before sowing; T2: 60 kg ha-1 sidedressed at V4 stage; and T3: 60 kg ha-1 before sowing + 60 kg ha-1 sidedressed). The following properties were evaluated: shoot dry matter, nutrient concentration and accumulation in the shoot, grain yield, and nutrient concentration and exportation in the grains. The NT age did not affect common bean yield, nutrition and response to N management. Nitrogen application, especially before sowing, led to higher dry matter and nutrient accumulation by common bean. The nutrient concentration in grains was little influenced by N fertilization. Grain yield and nutrient exportation were highest after double N application (before sowing and sidedressed) or only sidedressed at V4.

O impacto do Método Mãe Canguru no processo de aprendizagem de prematuros de baixo peso: Revisão da literatura

Technology advances and scientific studies in Neonatal Intensive Care Units (NICU) have contributed significantly to reduce mortality and morbidity of at-risk newborns (NB). However, they are more likely to present neurological and/or developmental psychomotor delay with neurological and sensory alterations. Therefore, proposals for neonatal intervention were developed with the aim of protecting the baby and offering appropriate incentives to minimize the effects of hospital intervention. To this end, programs of protective measures such as the Kangaroo Mother Care (KMC) were developed. Given the relevance of the issue described, this systematic review critically appraises articles from the national and international literature, published in recent years (from 2000 to 2011), that describe whether the KMC can be a protective factor for the development of writing in premature infants. The textual search was conducted using the Virtual Health Library (VHL), a website that covers publications worldwide, allowing access to articles from health science, including LILACS, IBECS, MEDLINE, Cochrane Library and SciELO, as database. The findings revealed that infants who participated in the KMC program showed improvements in their development and that factors such as low-birth-weight prematurity and learning disorders have close relationship with the onset of motor impairments and changes in psychomotor development. The findings showed no articles describing the KMC as a protective factor for the incidence of dysgraphia. Thus, we emphasize the importance of conducting further studies on these topics.

Exposição neonatal a drogas ototóxicas e possíveis alterações auditivas

Introduction: Scientific evidence indicates that neonatal exposure to ototoxic drugs cause hearing loss in newborns. Objective: To characterize the use of ototoxic antibiotics in newborns (NB), treated in the Neonatal Intensive Care Unit (NICU) and evaluate possible hearing modifications. Methods: A descriptive cross-sectional quantitative approach, using data from medical records of infants who were at some time in the NICU and used antibiotics, including ototoxic, from January to June 2004 as much as 2010, and the data were compared and analyzed. Parents/guardians of infants born in 2004 were contacted and applied a questionnaire containing questions about the children’s hearing. These children were submitted to audiological evaluation. Results: There was significant reduction in the time of use, the amount of antibiotics prescribed to newborns and Vancomycin prescription in 2010 compared to 2004. The hearing tests of 13 born in 2004 showed: sensorineural hearing loss in only 2 (one with moderate hearing loss and descending configuration in pure tone audiometry and the other with bilateral cochlear impairment); audiometric thresholds within the normal range in 11 patients, and the presence of otoacoustic emissions in 9. In Evoked Auditory Brainstem Response (ABR) no changes were observed. Conclusion: The reduction in the time of use, the amount and types of antibiotics observed may be related to the adoption of a Protocol in 2008, by the service. In contrast, auditory alterations may be related to a neonatal exposure to antibiotics in 2004.

Oficinas de férias experimentando genética: avaliação e contribuições para aprendizagem de alunos do ensino médio

Podemos observar que muitos jovens estão dispostos a mudar o mundo, porém, em contraste a essa afirmação, dados demonstram que ainda é grande o número evasão dos mesmos durante o Ensino Médio. Esse fato pode ser atribuído a diferentes motivos: a violência e ingresso na criminalidade, convivência familiar conflitante, má qualidade de ensino, falta de interesse ou a necessidade de trabalhar para ajudar a família ou a si próprio. Outro fator que contribui com a evasão escolar, é a falta de estímulos aos professores que, em geral, vêm sendo desestimulados pela baixa remuneração ou salários pouco atraentes, ausência de um plano de carreira promissor e recompensador, falta de infraestrutura adequada nas escolas e a falta de valorização profissional perante a sociedade, o que, por consequência, desestimula também o ingresso de jovens recém-formados na carreira da licenciatura. Nesse sentido, a necessidade de mecanismos que resgatem a qualidade do ensino nas escolas é eminente e a Universidade pode desempenhar um papel importante, pois representa uma fonte geradora de conhecimento e tecnologia, que nem sempre chegam à população. Assim a difusão de conhecimento e tecnologia, no Ensino Médio, representa um passo promissor na popularização da ciência e o início para a busca do interesse dos jovens ao conhecimento científico e suas tecnologias, através de oficinas e exposições que tem contribuído para a divulgação científica. Este trabalho tem o objetivo de avaliar a apreciação dos alunos do Ensino Médio que participaram de oficinas de férias propostas pelo Projeto de Extensão “Difundindo e popularizando a Ciência”. A pesquisa foi realizada por meio de sistematizações das respostas coletadas junto aos alunos que expressaram suas concepções sobre as oficinas a partir de formulários específicos. Num primeiro momento, trazemos dados, de 2007 a 2012, relativos a oficina Experimentando Genética, em ...

Avaliação da política curricular paulista: perspectiva docente sobre os cadernos do professor e do aluno

The current curriculum policy of the Secretary of Education in the State of Sao Paulo introduced into the education environment the Registrar of Teacher and Student - support material to ease the teacher's work and the student's learning, in order to address all the curriculum components created as strategy of learning. The resulting guidelines that aim to transform the everyday policies of educational institutions and the individuals who compose them, are incorporated into the school experience. These decisions, however, do not transfer into life outside the learning environment nor are they translated into the work of the teachers exactly as their creators intended. Thus, in order to better understand the curriculum policies introduced by the Registrar in schools, it is essential to comprehend the viewpoint of the teachers who themselves are both the targets and agents of curriculum policy, and later the Registrar. For that was made reflexive interviews with eigth teachers that teach in São Paulo metropolitan region, than we could see that they adapt their external determinations in their own reality

Dinâmica da secreção de néctar em Zeyheria montana Mart. (Bignoniaceae) relacionada à atividade dos beija-fores polinizadores

The Cerrado is home to important biodiversity areas in the state of Sao Paulo. Therefore, research on the reproduction of species of this biome are essential to help conservation programs. Pollination is the main mechanism by which outcrossing plants perpetuate their populations, and the attractive, such as nectar, are of vital importance to many anthophilous animals and essential to the maintenance of interactions with pollinators. In this context, the objective of this study was to investigate the ecological dynamics of secretion and sugar composition of floral nectar in Zeyheria montana, an ornithophilous exclusive Cerrado species, visited preferentially by Colibri serrirostris, also exclusive to this biome. This dynamic was assessed in isolated flowers in pre-anthesis, using microsyringes to collect nectar and manual refractometer to measure the concentration. Experiments were carried out to evaluate production throughout anthesis, including the assessment of total daily production, the effect of successive removal, the rate of production during the day and night and changes in concentration and composition of sugars, which was performed in HPLC (High Performance Liquid Chromatography). The rate of nectar production was about three times greater at night with a concentration two times lower, resulting in a supply of large amounts of dilute nectar in the early morning hours, peak of visitation for hummingbirds. Moreover, the production of nectar was more pronounced before the anthesis, and is available to visitors already in newly opened flowers, which are preferentially visited by C. serrirostris. There was an increase in the nectar production of flowers in the group with successive manual removal upon the control group, suggesting that the withdrawal by visitors stimulates the production, ensuring the availability of the resource including flowers previously visited...
