Avaliou-se 31 cães saudáveis, sem raça definida, sendo 10 machos e 21 fêmeas, com 8 meses a 7 anos de idade e peso de1,5-28 kg. Inicialmente foram mensurados os diâmetros fronto-occiptal (DFO) e bizigomático (DBZ) do crânio com o auxílio de um paquímetro. A ultra-sonografia transpalpebral em modo-B foi realizada para mensurar as estruturas do bulbo ocular, conforme se segue: D1- espessura da córnea; D2- distância entre o ponto central da imagem da córnea e a da cápsula anterior do cristalino (câmara anterior); D3- distância entre o ponto central da imagem da córnea e a da cápsula posterior do cristalino; D4- espessura do cristalino, que corresponde a distância entre a imagem da cápsula anterior e a cápsula posterior do cristalino; D5- diâmetro do cristalino, distância entre as imagens dos pólos do cristalino; D6– área do cristalino; D7- câmara vítrea, distância entre a imagem da cápsula posterior do cristalino e a retina; D8- distância entre a cápsula anterior do cristalino e a retina; D9- distância entre a imagem da córnea e a retina. Com exceção da D4, houve efeito dos DFO e DBZ sobre as medidas das estruturas internas do BO. A análise de regressão linear entre as medidas das estruturas do bulbo ocular e os DFO e DBZ foram significativas para D1, D2, D3, D4, D5, D6, D7, D8 e D9.

Este texto apresenta um recorte de um estudo mais amplo que teve como preocupação inicial a relação entre nominalização e transitividade em língua portuguesa. Tendo como suporte teórico a Teoria das Operações Enunciativas de A. Culioli (1990, 1999a, 1999b), caminhamos de uma análise estática e descritiva de língua, na qual essas questões têm visibilidade, para um estudo que levasse em consideração a articulação entre linguagem e línguas naturais. Esse segundo enfoque diluiu a especificidade dessas duas questões gramaticais e as direcionou para espaços de reflexão mais abstratos e comuns a qualquer problema gramatical tais como causalidade, propriedade diferencial e construção de domínios nocionais.

The objective of this study was to investigate the effect of the combined use of Azospirillum brasilense, humic acid and different levels of nitrogen on agronomic characteristics of wheat under greenhouse conditions. The experiments were installed on May 21, 2011 and proceeded to harvest on September 13, 2011. The experimental design was a randomized complete block in a 4 x 4 factorial design with four replications. The first factor relates to the combination of strain Ab-V5 of A. brasilense with humic acids, with the following treatments: control, Ab-V5, humic acid and Ab-V5 + humic acid and the second factor refers to nitrogen levels (0, 30, 60 and 90 kg ha-1 N). Most variables in the analysis had a positive linear effect of treatments depending on nitrogen fertilization, and only for variable weight of hundred grains, the negative effect was linear. There were no significant differences between the variances in grain production. It was concluded that the combined use of Ab-V5 + humic acid promotes the production mainly of dry leaves and are not responsive to nitrogen fertilizer for other productive components under study, as well as grain yield.

This text is part of a larger study that initially aimed at focusing the relation between nominalization and transitivity in the Portuguese Language. Based on A. Culioli´s Theory of the Enuntiative Operations, we started from a static and descriptive analysis of language, in which nominalization and transitivity have visibility, towards a study that takes into consideration the articulation between language and natural languages. This second approach diluted the specificity of these two grammatical questions and directed them to more abstract spaces of reflection and common to any grammatical problem, such as causality, differential propriety and the construction of notional domains.

One approach to verify the adequacy of estimation methods of reference evapotranspiration is the comparison with the Penman-Monteith method, recommended by the United Nations of Food and Agriculture Organization - FAO, as the standard method for estimating ET0. This study aimed to compare methods for estimating ET0, Makkink (MK), Hargreaves (HG) and Solar Radiation (RS), with Penman-Monteith (PM). For this purpose, we used daily data of global solar radiation, air temperature, relative humidity and wind speed for the year 2010, obtained through the automatic meteorological station, with latitude 18° 91' 66 S, longitude 48° 25' 05 W and altitude of 869m, at the National Institute of Meteorology situated in the Campus of Federal University of Uberlandia - MG, Brazil. Analysis of results for the period were carried out in daily basis, using regression analysis and considering the linear model y = ax, where the dependent variable was the method of Penman-Monteith and the independent, the estimation of ET0 by evaluated methods. Methodology was used to check the influence of standard deviation of daily ET0 in comparison of methods. The evaluation indicated that methods of Solar Radiation and Penman-Monteith cannot be compared, yet the method of Hargreaves indicates the most efficient adjustment to estimate ETo.

Performance of cyclical and discrete movements executed in Fitts’ task simulated by computer Abstract This study compared the performance of cyclical and discrete movements in Fitts’ task simulated by a computer. Twenty male adults, between 25 and 30 years old, participated as volunteers in the study. The software Discrete Aiming Task (v.2.0) simulated the Fitts’ task, in the discrete and cyclical conditions, and provided the movement time (TM). It was manipulated 4 target widths and 3 distances between the targets to provide index of difficulties (ID) from 1 to 6 bits. The ANOVA TWO WAY, 3 (Conditions) x 6 (ID), with repeated measures in the last factor, compared the TM in the different conditions. Regression analysis verified the relationship between TM x ID. There were no significant differences between the conditions; the virtual environment and the mouse were used to explain such results. All movement conditions showed a straight relationship between TM x ID with R²>0.990. Therefore, Fitts’ law showed to be consistent, independently of the movement strategy performed.
