Efeito de Embalagens e do tratamento com fungicida na qualidade de sementes de soja armazenadas.

Este trabalho objetivou avaliar o efeito de dois tipos de embalagens e do tratamento fungicida na qualidade de sementes de soja armazenadas. Sementes de soja das cultivares FT-Estrela e MT/BR 51 (Xingu), tratadas e não tratadas com os fungicidas tiofanato metílico, tolylfluanid, carbendazin e benomyl, foram armazenadas (em sacos de papel e em sacos de polietileno) em armazéns convencionais em Ponta Porã, MS e Rondonópolis, MT, respectivamente. Uma máquina da marca Amazone Transmix foi utilizada para fazer o tratamento. A cada 60 dias foram realizadas avaliações dos seguintes parâmetros: umidade das sementes, sanidade de sementes (blotter test), germinação padrão, vigor no tetrazólio, emergência em areia e emergência a campo. Não foi observado efeito negativo do tratamento com fungicida e do tipo de embalagem sobre a qualidade das sementes durante o período de armazenamento. De uma maneira geral, a germinação, o vigor das sementes e a emergência das plântulas foram mantidos durante o período de 180 dias de armazenamento. Observou-se melhor conservação das sementes tratadas com fungicidas durante o período em que elas ficaram armazenadas, em comparação às sementes não tratadas. Assim, ficou demonstrada a viabilidade técnica do tratamento de sementes de soja com fungicidas antes do armazenamento. Foi observada redução da germinação, emergência e vigor quando os fungicidas benzimidazóis (tiofanato metílico, carbendazin e benomyl) foram aplicados isoladamente às sementes de soja. Não foi observada variação significativa na umidade das sementes durante o período de armazenamento das mesmas.bitstream/item/69246/1/BP10-02-augusto.pd

The landscape of nonlinear structural dynamics: an introduction.

Nonlinear behaviour is ever-present in vibrations and other dynamical motions of engineering structures. Manifestations of nonlinearity include amplitude-dependent natural frequencies, buzz, squeak and rattle, self-excited oscillation and non-repeatability. This article primarily serves as an extended introduction to a theme issue in which such nonlinear phenomena are highlighted through diverse case studies. More ambitiously though, there is another goal. Both the engineering context and the mathematical techniques that can be used to identify, analyse, control or exploit these phenomena in practice are placed in the context of a mind-map, which has been created through expert elicitation. This map, which is available in software through the electronic supplementary material, attempts to provide a practitioner's guide to what hitherto might seem like a vast and complex research landscape.This project has arisen from a collaboration between the five UK universities and eight industrial collaborators on the EPSRC ‘Engineering Nonlinearity’ Programme Grant (EPSRC grant no. EP/K003836/1). T.B. is funded by an RAEng/EPSRC Research Fellowship.This is the final version of the article.

Validating Variational Bayes Linear Regression Method With Multi-Central Datasets.

PurposeTo validate the prediction accuracy of variational Bayes linear regression (VBLR) with two datasets external to the training dataset.MethodThe training dataset consisted of 7268 eyes of 4278 subjects from the University of Tokyo Hospital. The Japanese Archive of Multicentral Databases in Glaucoma (JAMDIG) dataset consisted of 271 eyes of 177 patients, and the Diagnostic Innovations in Glaucoma Study (DIGS) dataset includes 248 eyes of 173 patients, which were used for validation. Prediction accuracy was compared between the VBLR and ordinary least squared linear regression (OLSLR). First, OLSLR and VBLR were carried out using total deviation (TD) values at each of the 52 test points from the second to fourth visual fields (VFs) (VF2-4) to 2nd to 10th VF (VF2-10) of each patient in JAMDIG and DIGS datasets, and the TD values of the 11th VF test were predicted every time. The predictive accuracy of each method was compared through the root mean squared error (RMSE) statistic.ResultsOLSLR RMSEs with the JAMDIG and DIGS datasets were between 31 and 4.3 dB, and between 19.5 and 3.9 dB. On the other hand, VBLR RMSEs with JAMDIG and DIGS datasets were between 5.0 and 3.7, and between 4.6 and 3.6 dB. There was statistically significant difference between VBLR and OLSLR for both datasets at every series (VF2-4 to VF2-10) (P < 0.01 for all tests). However, there was no statistically significant difference in VBLR RMSEs between JAMDIG and DIGS datasets at any series of VFs (VF2-2 to VF2-10) (P > 0.05).ConclusionsVBLR outperformed OLSLR to predict future VF progression, and the VBLR has a potential to be a helpful tool at clinical settings

Inverse Anticipating Synchronization

We report a new type of chaos synchronization:inverse anticipating synchronization, where a time delay chaotic system can drive another system in such a way that the driven system anticipates the driver by synchronizing with its inverse future state. We extend the concept of inverse anticipating chaos synchronization to cascaded systems. We propose means for the experimental observation of inverse anticipating chaos synchronization in external cavity lasers.Comment: LaTex 6 pages, resubmitted to PR

Parameter Mismatches and Perfect Anticipating Synchronization in bi-directionally coupled external cavity laser diodes

We study perfect chaos synchronization between two bi-directionally coupled external cavity semiconductor lasers and demonstrate for the first time that mismatches in laser photon decay rates can explain the experimentally observed anticipating time in synchronization.Comment: Latex 4 page

Development and pathology of echinostoma caproni in experimentally infected mice

In the present article, several parasitological features of mice, each experimentally infected with 75 metacercariae of Echinostoma caproni (Trematoda: Echinostomatidae), were studied during the first 12 wk postinfection. Moreover, the early pathological responses also were analyzed and compared with data previously published on other host species of E. caproni to gain further insight into the factors determining worm rejection or establishment of chronic infections. The results obtained show that the pattern of E. caproni infection in mice is consistent with a highly compatible host–parasite system. This combination is characterized by a high worm establishment, high egg output, and long survival of the worms. However, some differences with respect to other highly compatible hosts have been observed, particularly in relation to the survival of the adult worms. Histological studies suggest that the kinetics of goblet cells, mucosal neutrophils, and mononuclear inflammatory cells in the mesentery seem to be essential in determining the course of E. caproni infection in mice.Sotillo Gallego, Javier, [email protected] ; Monteagudo Castro, Jose Carlos, [email protected] ; Marcilla Diaz, Antonio, [email protected]
